Subject: [PATCH 002/240] fix(agent): match enum-style reasoning_effort
 rejections with no unsupported marker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commandcode.ai rejects the top-level `reasoning_effort: "none"` (the
disabled-reasoning encoding CustomProfile projects) with an enum 400 —
"Invalid option: expected one of \"low\"|\"medium\"|\"high\"|\"xhigh\"|\"max\""
— whose message carries no "unsupported" marker at all: the field name
appears only in the structured 'param' tail, outside the ±32 near-window
of the token match, and no UNSUPPORTED_PARAM_MARKERS entry matches the
enum wording. is_reasoning_field_rejection never fires, so the
strip-and-retry rung (#112781) is skipped and title generation fails
outright (#115277).

Add the enum wording to UNSUPPORTED_PARAM_MARKERS so both surfaces (the
main-loop reasoning_mandatory rung and the auxiliary ladder) recognise
it; a non-reasoning 'param' (temperature) stays unmatched because no
reasoning field token appears anywhere.

Subject: [PATCH 003/240] fix: recognize structured reasoning-field 400s (param
 / invalid_reasoning_effort) as reasoning rejections
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A custom OpenAI-compatible Responses relay rejects an unsupported
`reasoning.effort` with a message-less structured 400 —
`{"error": {"param": "reasoning.effort", "error_code":
"invalid_reasoning_effort", "retryable": false}}` (#100536). No wording
rule in `is_reasoning_field_rejection` could match an empty message, so
the 400 fell through `_classify_400` to the generic large-session
overflow heuristic and the loop compressed a conversation that had
nothing to do with context size ("Context length exceeded (77 tokens).
Cannot compress further.").

Read the structured signal from the stringified body instead: a `param`
naming a reasoning wire field (`reasoning_effort`, `reasoning.effort`,
`thinking_config`, ...) or an `invalid_reasoning_effort` code is a
reasoning-field rejection whatever the message says. This is the same
predicate the auxiliary strip-and-retry rung uses, so title generation
recovers too. The main loop then takes the existing one-shot
reasoning-disable retry and, when spent, the fallback chain that
surfaces the provider's real error — never compression.

Control: a genuine context-window 400 still classifies context_overflow
with should_compress on; a `param: temperature` enum rejection does not
match.

Subject: [PATCH 004/240] fix(auth): status and doctor Codex reads never adopt,
 refresh or persist credentials
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`hermes status` / `hermes doctor` / the dashboard cards and the `/model` picker
call `get_codex_auth_status()`, whose singleton fallback ran
`resolve_codex_runtime_credentials()` with runtime defaults: a store missing
its refresh_token imported the Codex CLI's single-use token family, and an
expiring token was refreshed and written back. A diagnostic that spends or
borrows a rotating refresh token logs the other program out (#68004).

`resolve_codex_runtime_credentials(read_only=True)` reports the stored state
as-is (no CLI adoption, no refresh, no pool forced refresh, no write) and wins
over `force_refresh`; the Codex status snapshot uses it, and the xAI OAuth
snapshot passes `refresh_if_expiring=False` for the same reason. The pool side
was already an observation (`peek`, 964fbaae2cb).

Superseded #68224 (@GauravPatil2515) — same mechanism, re-done on the current
`auth_codex` layout.

Subject: [PATCH 005/240] feat(codex_app_server): accept developer_instructions
 and send them on thread/start

CodexAppServerSession(developer_instructions=...) forwards Hermes' composed
system prompt as thread/start.developerInstructions when non-empty. Codex keeps
its own base instructions and inserts the text as the first developer message
of every model request, so SOUL.md / memory / channel overrides finally reach
the model on this runtime.

Hand-ported from #27998 (the developerInstructions half only; the SOUL-only
baseInstructions hunk is dropped because baseInstructions REPLACES codex's base
tool guidance, and #74712's own probe table shows the `instructions` spelling is
accepted but ignored).

Part of #74712 #26035

Subject: [PATCH 006/240] fix(codex_app_server): disable codex's built-in
 personality on thread/start

Hermes supplies its own agent identity and personality through the system
prompt. Sending personality: "none" on thread/start strips codex's built-in
"# Personality" section from the base instructions (verified against codex
0.147: the section disappears from the outgoing model request and thread/start
is accepted without error), so it can no longer compete with SOUL.md.

Hand-ported from #72106 (its test hunk is folded into the lane's own invariant
test commit).

Fixes #72104

Subject: [PATCH 007/240] fix(codex_runtime): hand Hermes' composed system
 prompt to the codex thread

The codex_app_server early-return forked away from the standard loop before any
prompt assembly was used: the codex thread received only cwd and the raw user
text, so SOUL.md, MEMORY.md/USER.md and channel_overrides.system_prompt were
composed, persisted to sessions.system_prompt, and then silently discarded.

_ensure_codex_session now composes the prompt exactly as turn_context does
(agent._cached_system_prompt + "\n\n" + agent.ephemeral_system_prompt) and
passes it to CodexAppServerSession(developer_instructions=...) once per thread.
Sessions are created lazily per turn only when none exists, so the prompt is
never duplicated per turn and a retired session re-sends the current one.

Hand-ported from #74726: same composition, but the session kwarg is spelled
developer_instructions -> thread/start.developerInstructions because the
`instructions` field #74726 used is accepted and ignored by codex.

Subject: [PATCH 008/240] test(codex_app_server): invariants for the Hermes
 prompt handoff; docs

Session: thread/start carries developerInstructions + personality "none", and
omits developerInstructions when the prompt is blank (folds #72106's assertion
into the rewritten cwd-only test). Runtime: _ensure_codex_session composes
_cached_system_prompt + ephemeral_system_prompt exactly like turn_context and
sends it once per thread across turns; no field when the agent has no prompt.

Docs state that SOUL.md / system prompt / channel overrides now reach the model
as developer instructions and that conversation history is still not projected
into the codex thread. Contributor mapping for @Momentum96 (#27998 port).

 - **Hermes auth and codex auth are separate sessions.** You need both `codex login` AND `hermes auth add openai-codex` for the cleanest UX (the runtime uses codex's session for the LLM call). This is a deliberate design choice in Hermes' `_import_codex_cli_tokens` — Hermes won't share OAuth state with codex CLI to avoid clobbering each other on token refresh.
 - **`delegate_task`, `memory`, `session_search`, `todo` are unavailable on this runtime.** They need the running AIAgent context which a stateless MCP callback can't provide. Use `/codex-runtime auto` when you need these.
 - **No inline patch preview in approval prompts when codex doesn't track the changeset.** Codex's `fileChange` approval params don't always carry the changeset. Hermes caches the data from the corresponding `item/started` notification when possible, but if approval arrives before the item has streamed, the prompt falls back to whatever `reason` codex provides.
+- **Conversation history is not projected into the codex thread.** The codex thread receives Hermes' system prompt when it starts plus each new user message; prior Hermes history (e.g. from a resumed session) is not replayed into it. Prompt changes made mid-session apply when the thread is next (re)created.
 - **Sub-second cancellation isn't guaranteed.** Mid-stream interrupts (Ctrl+C while codex is responding) are sent via `turn/interrupt`, but if codex has already flushed the final message, you get the response anyway.
 
 If you find a bug, [open an issue](https://github.com/NousResearch/hermes-agent/issues) with the output of `hermes logs --since 5m`. Mention `codex-runtime` in the title so it's easy to triage.

Subject: [PATCH 009/240] fix(acp): forward the resolved credential pool into
 ACP agents
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

resolve_runtime_provider() selects a provider-scoped credential pool and returns
it as runtime["credential_pool"]; oneshot and the gateway hand it to AIAgent, but
acp_adapter/session.py::_make_agent dropped it, so a long-lived ACP process had
_credential_pool=None and could not refresh/rotate on HTTP 401 after OAuth
token expiry — the only recovery was restarting the ACP process (#70292).

Forward the pool by identity like the other surfaces. The pool is already
provider-scoped and its selected entry matches the agent's initial api_key, so
the existing account-isolation guards are preserved rather than bypassed.

Salvaged from PR #70293 (the cherry-pick claimed in #77029 never reached
acp_adapter/session.py); regression test asserts the pool object is retained.

Fixes #70292

Subject: [PATCH 010/240] fix(codex): stop double-counting cached input in
 app-server usage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_record_codex_app_server_usage fed inputTokens — which the app-server protocol
reports INCLUSIVE of cachedInputTokens — into CanonicalUsage.input_tokens while
also recording cachedInputTokens as cache_read. CanonicalUsage.prompt_tokens sums
both buckets, so cached tokens were counted twice: inputTokens=80,
cachedInputTokens=20 produced prompt_tokens=100 instead of 80. The inflated value
reached session accounting, cost estimation and context_compressor.last_prompt_tokens
(premature compaction) on every cache-hit turn (#105412, #63654, #48801).

Subtract cache_read from the reported input to get the uncached remainder,
mirroring normalize_usage's codex_responses branch so both Codex transports yield
identical accounting. The transport exposes no cache-write, so only cache_read is
subtracted. totalTokens stays the provider passthrough. The existing integration
test asserted the wrong totals; it now pins prompt=80, uncached=60, cached=20.

Ported from PR #63654 onto the current adapter shape.

Fixes #105412

Subject: [PATCH 011/240] fix(oneshot): consult the fallback chain at provider
 resolution time
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

hermes_cli/oneshot.py::_run_agent called resolve_runtime_provider() bare. When the
primary's credential pool is exhausted (quota 429), expired, or cooled down, that
raises AuthError before AIAgent exists, so the mid-session fallback_model wiring
never gets a chance and `hermes -z` dies for the whole quota window even with a
healthy fallback_providers chain configured — the gateway
(_try_resolve_fallback_provider) and the interactive CLI (_resolve_fallback_runtime)
already walk the chain at resolution time (#81209).

Add one shared hermes_cli/runtime_provider.py::resolve_runtime_with_fallback():
AuthError-only trigger (ValueError misconfiguration such as a typo'd --provider still
fails loudly instead of being rerouted), get_fallback_chain() semantics (managed
overlay, key_env, effective_runtime_provider identity), primary-error precedence when
every entry fails. Oneshot uses it and sends the chosen entry's model; the primary's
stored api_mode is dropped on a switch. The helper is the extraction point for the
auxiliary/curator ports (#82132, #79750) and the gateway loop.

Salvaged from PR #81562 (AuthError-only, injectable resolver, oneshot wiring) with the
chain-walk and error-precedence properties adjudicated from PR #81517.

Fixes #81209

Subject: [PATCH 012/240] fix(codex): rotate the credential pool on Responses
 HTTP-200 soft failures
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Codex Responses API reports quota exhaustion as HTTP 200 with
`response.status == "failed"` and `error.code == "usage_limit_reached"`.
The SDK never raises, so the exception path's credential-pool rotation
(`recover_after_classification` -> `_recover_with_credential_pool`) never
saw it: `retry_invalid_response` retried the same exhausted account
`max_retries` times and then went straight to cross-provider fallback,
leaving a healthy sibling pool entry unused and the dead entry unmarked.

Fix: `turn_recovery.classify_codex_soft_failure` reshapes `response.error`
as an SDK-style error body and runs it through the existing
`classify_api_error` / `extract_api_error_context` (no second pattern
list); `retry_invalid_response` then tries same-provider pool recovery
FIRST for rate_limit / billing / auth verdicts and falls through to the
existing eager fallback + retry path otherwise. Content-policy and other
non-quota failures never rotate. The `ResponseError` repr that leaked into
the retry trace now shows the provider's message.

Live probe (fake Responses SSE server, 2-entry pool, real AIAgent loop):
before -> 3 requests on tok-A, pool untouched, turn failed;
after  -> 1 soft failure on tok-A, cred-0 exhausted (usage_limit_reached),
          rotated to tok-B, turn completed; content_policy control -> no
          rotation on either side.

Fixes #24159
Salvages #24173 (@jmmaloney4) — recovery order and insertion point; the
hand-rolled pattern classifier is replaced by the shared error classifier.

Subject: [PATCH 016/240] fix(providers): bare `provider: custom` honours
 model.key_env; an unset key_env is logged instead of laundered into
 no-key-required
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`model.provider: custom` + `model.base_url` + `model.key_env` (the wizard's bare-custom
shape) resolved through `_resolve_openrouter_runtime`, whose candidate list only knew
`model.api_key` and the host-gated OPENAI/OPENROUTER env keys — `model.key_env` was never
read, so every request went out as `Bearer no-key-required` and the endpoint returned
401/403 in tens of milliseconds (#67453). The same rung is what the API server platform
resolves on each request, which is why the reporter saw it on every request.

- `_model_cfg_key_env_for()` supplies the declared variable's value on the bare-custom and
  direct-alias rungs, only when the target base_url IS the configured `model.base_url`
  (a CUSTOM_BASE_URL or alias endpoint elsewhere never receives that key).
- `_key_env_secret()` is the one key_env/api_key_env reader for custom blocks (model block
  and custom_providers entries): a declared variable that resolves to nothing is now
  WARNING-logged before the `no-key-required` substitution, so a misnamed/unexported var
  points at the Hermes config instead of the provider's IAM. Blocks with no key_env stay
  silent — that is the keyless local-server configuration.
- `is_output_cap_error()` recognises "max_completion_tokens is limited to N" (Scaleway), so
  the budget step-down triggers instead of the compressor (second atom of #67453).

Supersedes #67554 (@JonthanaHanh), which added the same lookup on the explicit-base_url
branch only.

Subject: [PATCH 017/240] fix(codex): make the post-terminal drain budget a
 config key (agent.stream_drain_timeout)

Replace the hardcoded 2.0s module constant from the salvaged commit with
``agent.stream_drain_timeout`` in DEFAULT_CONFIG (default 2.0, ``0`` skips the
drain), read through ``load_config_readonly`` at drain time. Non-secret knobs
belong in config.yaml, not a new HERMES_* env var. Documents the budget in the
timeouts table and adapts the salvaged test to the new seam.

Why: a relay that never closes the SSE socket after ``response.completed``
wedged the turn until the stale watchdog fired and discarded the already-billed
response (#103864). The drain is a courtesy to Relay's finalizer, so it must be
bounded; the bound needs a user-tunable knob for slow-but-honest relays.

 The **socket read timeout** controls how long httpx waits for the next chunk of data from the provider. Local LLMs can take minutes for prefill on large contexts before producing the first token, so Hermes raises this to 30 minutes when it detects a local endpoint. If you explicitly set `HERMES_STREAM_READ_TIMEOUT`, that value is always used regardless of endpoint detection.

 The **stale non-stream detection** kills non-streaming calls that produce no response for too long. By default Hermes disables this on local endpoints to avoid false positives during long prefills. If you explicitly set `providers.<id>.stale_timeout_seconds`, `providers.<id>.models.<model>.stale_timeout_seconds`, or `HERMES_API_CALL_STALE_TIMEOUT`, that explicit value is honored even on local endpoints.
 
+The **post-terminal stream drain** bounds how long a Codex/Responses stream keeps reading after its terminal `response.completed` frame (a courtesy so the relay finalizer can run). Some relays never close the SSE socket after the terminal frame; without a bound the turn wedged until the stale-stream watchdog fired and discarded the already-billed response, then retried. After `agent.stream_drain_timeout` seconds the stream is closed and the completed response is returned. Endpoints that close the connection normally finish the drain immediately and never wait this long; set `0` to skip the drain entirely.
+
 This budget bounds every non-streaming call. A provider that accepts a request and then goes silent — connection held open, no bytes, no error — is aborted at the stale timeout and retried, rather than hanging until the much longer socket read timeout (or, for an unattended cron run, until something external kills the process).
 
 The periodic provider-wait notice appears only after at least **60 seconds of silence**. The Codex Responses **waiting status** describes silence, not total generation time: active stream events (including reasoning) keep it quiet. If events stop, it reports time without stream events instead of claiming no response has arrived; the notice clears when events resume. When a reconnect starts a fresh first-event watchdog phase, the waiting status follows that phase. This display behavior does not extend the separate wall-clock stale-call budget or change watchdog timeouts. Chat-completion streams likewise clear their silence warning promptly when chunks resume, without replacing a local model-loading status.

Subject: [PATCH 018/240] fix(codex): record first Responses stream event
 timing

Responses lifecycle events may arrive before answer text, but the streaming runtime never populated the existing post_api_request timing field. Record the first accepted event while preserving request-retirement fencing.\n\nCloses #105311.

Subject: [PATCH 019/240] feat(api-server): stream model reasoning on
 /v1/chat/completions and /v1/responses

OpenAI-compatible clients (Open WebUI, opencode, LibreChat, the Vercel AI SDK)
saw only answer text from the API server: the streaming writers never wired the
agent's structured ``reasoning_callback``, so reasoning deltas that every native
surface already renders were dropped at the transport boundary (#99552).

- `_spawn_stream_agent` passes a `reasoning_callback` (via `_run_agent` /
  `_create_agent`) that tags deltas `("__reasoning__", text)` on the stream queue,
  keeping them distinct from answer text. The lossy 500-char `reasoning.available`
  progress preview is deliberately not used.
- `/v1/chat/completions`: reasoning rides `choices[0].delta.reasoning_content`
  (the DeepSeek-style field those clients render as a thinking block).
- `/v1/responses`: each thinking burst is a spec-native `reasoning` output item
  (`output_item.added`, `reasoning_summary_part.added`,
  `reasoning_summary_text.delta/done`, `reasoning_summary_part.done`,
  `output_item.done`), closed before the next message/function_call item opens
  and echoed in `response.completed` output; `sequence_number` stays monotonic.
- `GET /v1/capabilities` advertises `features.reasoning_streaming: true`.
- Docs: api-server page documents the wire fields and the capability flag.

Gating is unchanged: nothing is emitted unless the model produces reasoning under
the resolved `reasoning_config` (`model_options.reasoning.enabled: false` opts out).

Subject: [PATCH 020/240] fix(acp): rejected session/set_model is an
 invalid-params error and a failed rebuild reports its real cause

set_session_model already validates through hermes_cli.model_switch.switch_model
(11576390fec), so an unadvertised modelId is refused before the session mutates
(#72439's main atom). The rejection surfaced as JSON-RPC -32603 "Internal error"
though, which clients attribute to the agent rather than to the request; it is now
RequestError.invalid_params (-32602) carrying the switch_model reason. _switch_model
also assigned state.model before the rebuild, so an agent-build failure left the
session persisted on a model the live agent did not run; the assignment now follows
the successful build.

_make_agent swallowed a resolve_runtime_provider failure at debug and built a bare
AIAgent, which dies with the first-run "No LLM provider configured. Run `hermes
setup`" text on a configured machine (#91090's residual ask). The fallback stays, but
when the bare build fails the swallowed resolution error (revoked OAuth, disabled
provider, ...) is raised instead, chained to the fallback failure.

Direction credited to @z0zero (#72579: -32602 + atomic session state) and
@webtecnica (#91100: do not swallow the resolution failure).

Subject: [PATCH 022/240] refactor: inline the pre-stream transport-cause check
 in run_codex_stream

The OpenAI SDK always raises ``APIConnectionError(...) from err`` with the
httpx transport error as the direct ``__cause__``, so the chain-walking
helper from the salvaged commit is more machinery than the signal needs.
Replace it with an ``isinstance(exc.__cause__, httpx.TransportError)``
check at the single call site and document WHY the raw
``transport_errors`` branch never sees a pre-stream failure (the SDK wraps
them), which is the root cause behind #103673.

Subject: [PATCH 023/240] fix(gateway): surface fallback notice when credential
 resolution falls back to secondary provider

When the primary provider fails with AuthError during gateway credential
resolution (before AIAgent is constructed), the fallback provider is
silently used with no user-visible notice. The existing
_pending_fallback_notice mechanism only covers in-conversation-loop
fallback activation, not the pre-agent gateway path.

Fix by:
1. Capturing primary provider/model from config in
   _resolve_runtime_agent_kwargs() before the AuthError try block
2. Adding _fallback_notice metadata to the returned fallback dict
3. Popping it in TurnRunner.run_sync() before forwarding kwargs
4. Setting agent._pending_fallback_notice after agent creation/cache

The existing _emit_pending_fallback_notice() mechanism then surfaces
the notice on the next turn, deduplicating naturally.

Fixes #74349

(cherry picked from commit 7d66877ecb4718dbfebc7729e7a0ea96d8eab174)

Subject: [PATCH 024/240] fix: keep the pre-agent fallback notice out of
 AIAgent kwargs; surface it from the turn runner

The notice is stashed on the runner in _resolve_session_agent_runtime and popped once per turn, so the private key never reaches an AIAgent(**runtime_kwargs) spread (hygiene, background tasks, api_server); TurnRunner now lives in gateway/run_turn_runner.py.

Subject: [PATCH 025/240] fix(opencode): send ephemeral x-opencode-session
 header on one-shot requests

OpenCode Go strictly requires an x-opencode-session header on all requests to route requests efficiently and avoid HTTP 400 MissingSessionID. In turn chats and parented auxiliary calls, the header is derived from the conversation context or session ID. For stateless one-shot requests (commit messages, summaries, unparented auxiliary tasks), opencode_session_headers now falls back to generating an ephemeral session ID so one-shot requests to OpenCode succeed.

Closes #105841

Subject: [PATCH 026/240] fix: hand Codex reasoning-only stalls to the fallback
 provider instead of the incomplete sentinel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three consecutive Codex Responses answers that carry only (encrypted) reasoning —
no visible text, no tool call — used to exhaust the 3-continuation budget and end
the turn on "Codex response remained incomplete after 3 continuation attempts",
never touching configured fallback_providers (#67321). Encrypted reasoning items
replay byte-for-byte, so a bare retry deterministically repeats the stall.

- Track a per-turn `_codex_reasoning_only_streak` apart from the aggregate
  `_codex_incomplete_retries`: a visible partial resets the streak, so the mixed
  partial-then-stall variant still reaches its own recovery threshold while the
  turn-wide iteration budget stays the hard bound.
- At streak 3, `continue_codex_incomplete` activates the next fallback with the
  semantic `FailoverReason.incomplete_response`, grants exactly one grace call when
  the trigger consumed the last iteration, and returns `CODEX_FALLBACK_ACTIVATED`;
  the intake re-syncs the Model:/Provider: identity on the system prompt.
- Off the Codex wire the synthetic continuation nudge is stripped alongside the
  opaque replay state (`drop_nudge_marker`) so the Chat Completions payload keeps
  valid role ordering and no Codex-only control text.
- No fallback configured: unchanged terminal sentinel, still bounded at 3 calls.

Ported from PR #67336 by @PRATHAMESH75 onto the decomposed agent/turn_*.py siblings.

Subject: [PATCH 027/240] fix(providers): opencode-go vision models stay on the
 Go endpoint and attach images natively
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two independent gaps hit a user on provider opencode-go with
deepseek-v4-flash-vision-exp (#96066):

- Vision: the model is absent from models.dev, so get_model_capabilities()
  returned None and image_input_mode: auto detoured images through the lossy
  text describe path. OpenCode Zen/Go resell vendor previews before the catalog
  indexes them; the id's `-vision` token is the vendor's own capability marker,
  so _apply_overrides() now fills the catalog gap with a vision-only base for
  any OpenCode-family provider (built-in or family-slug custom). Catalog entries,
  explicit and _default overrides stay authoritative; reasoning stays unknown.

- Route: _resolve_agent_model_runtime() applied a resumed row's persisted
  api_mode/base_url verbatim. A row written while the session ran an
  anthropic_messages model (MiniMax on Go, or an older build's /zen/v1 relay)
  pinned that wire onto a chat_completions model, surfacing as 401s from the
  Anthropic transport or the Zen relay. Providers that pick the wire per model
  (OpenCode families, Copilot, Nous — the existing _PROVIDER_API_MODE_OVERRIDES
  table, now reachable via model_derived_api_mode()) re-derive api_mode from the
  target model on resume and heal the relay URL; fixed-wire providers keep
  honoring their row.

Salvages #96116 (@Finn763): same two atoms, redone slim (data-driven table
instead of an opencode-only hostname guard in the tui_gateway facade).

Subject: [PATCH 028/240] fix(dashboard): custom endpoint validation persists
 the base URL that served /models (#65488)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A custom OpenAI-compatible endpoint typed without `/v1` in the Desktop
onboarding or Settings > Custom endpoints flow was probed only at
`{base}/models`, while the CLI's probe_api_models falls through to the
`/v1` alternate. Whatever the probe reported, the URL was saved verbatim
and the runtime POSTs `{base_url}/chat/completions` to it, so a server
that only serves `/v1/*` 404'd every chat request.

Both dashboard validators (`/api/providers/validate` OPENAI_BASE_URL
branch and `/api/providers/custom-endpoints/validate`) now share one
probe that tries the URL as entered and then its `/v1` variant (or the
stripped variant), and return `resolved_base_url` — the base that
actually served the model list. The Desktop onboarding persists that
URL, and the Settings "Test" rewrites the form's URL to it so the
following Save stores a URL chat can reach.

 ephemeral x-opencode-session key

The providers page listed every OpenCode caller that carries the affinity header; add the
stateless one-shot case (Desktop commit-message generation with no active session), which
now sends a fresh ephemeral key instead of nothing so the relay no longer rejects it with
400 MissingSessionID (#105841).

 The two built-in OpenCode providers each pin their own relay on `opencode.ai` (`opencode-zen` → `/zen/v1`, `opencode-go` → `/zen/go/v1`). A `model.base_url` left behind by the other relay is healed to the selected provider's relay, and the model you pick (`-m`, `/model`, a fallback entry or a channel override) decides which relay is used — so switching from a Zen model to a Go-only one never sends the request to Zen. A custom provider you define under `providers:` whose name extends a family slug (for example `opencode-go-bridge`) still gets the family's per-model API-mode routing and `/v1` handling, but its `base_url` is taken as declared: name it after the relay it actually points at.

Subject: [PATCH 030/240] fix(tui_gateway): adopt fallback_providers edits into
 open Desktop/TUI chats at turn start

Desktop and TUI sessions keep one AIAgent across turns and _make_agent read the
fallback chain exactly once. A chat opened before `hermes fallback add` therefore
kept an empty _fallback_chain forever: on a Codex 429 usage_limit_reached the pool
exhausted both credentials, the loop found "No fallback providers configured", and
the turn ended in a provider error even though a healthy fallback was on disk.

The messaging gateway already re-applies its cached agents' chain per message
(GatewayRunner._apply_fallback_chain_to_agent, #60955). Run the same helper on the
turn thread right beside the model/compression config syncs, fail-open, so a chain
added or edited while a chat is open reaches its next turn without a new chat.

Live probe (fake primary replaying the Codex 429 body, 2-entry pool, fake fallback
answering 200, real AIAgent loop): before -> 5 requests to the primary, no switch,
"rate-limited every one of 3 attempts"; after -> pool exhausts, fallback activates,
completed=True "hello from B".

Part of #95066 (atoms 1+2: chain refresh and fallback activation; the error-card "Switch provider" button remounting the live session is a separate Desktop UI change)
Salvages #95139 (slim redo of the turn-start sync; the JWT account dedupe hunk was
dropped: on main the pool rotation exhausts both entries and falls back in the same
turn, so it is not needed to reach the fallback).

Subject: [PATCH 031/240] fix(tts): honor the PCM sample rate reported by
 OpenAI-compatible endpoints

Local OpenAI-compatible /v1/audio/speech servers (Echo-TTS at 44.1 kHz, Piper at
22.05 kHz) played back at half speed because OpenAIStreamer, the speaker
OutputStream, the temp-WAV header and the gateway AudioFormat were all pinned to
OpenAI's 24 kHz before the request was even sent.

- OpenAIStreamer reads `X-Audio-Sample-Rate` (or `rate=` in Content-Type) from
  the response and updates `sample_rate` before yielding the first chunk; a
  validated `tts.openai.pcm_sample_rate` (DEFAULT_CONFIG, 24000) is the
  pre-request expectation for servers that report nothing.
- _StreamerPlayback opens PortAudio after a sentence's first chunk arrived (and
  reopens when the rate changes); the temp-WAV path already drained chunks
  before writing its header, so it now reads the final rate.
- StreamingTTSConsumer opens the adapter handle on the first PCM chunk with the
  streamer's now-final AudioFormat instead of at construction, so gateway
  adapters receive the reported rate through the existing sample_rate metadata
  (no resampling).

Slim redo of PR #76501 (@webtecnica) without its NumPy resampler, plus the
static config key from PR #74021 (@valda). Fixes #76466.

+**Streaming sample rate (OpenAI-compatible endpoints)**: streaming playback receives headerless raw PCM, so Hermes must know its sample rate. The official OpenAI API emits 24 kHz. A compatible server that reports its rate — the `X-Audio-Sample-Rate` response header, or `rate=` in the `Content-Type` (`audio/pcm; rate=44100`) — is honored automatically: the speaker, the temp-WAV player and the gateway audio stream all open at the reported rate once the response arrives. For servers that report nothing, set `tts.openai.pcm_sample_rate` to the endpoint's output rate (e.g. `22050` for Piper-backed servers); otherwise speech plays at the wrong speed and pitch. Invalid values log a warning and fall back to `24000`.
+
 **Language (OpenAI-compatible endpoints)**: `tts.openai.language` is forwarded to the endpoint as a `lang_code` request parameter. It is intended for OpenAI-compatible TTS servers that support `lang_code` — for example [Kokoro-FastAPI](https://github.com/remsky/Kokoro-FastAPI), where `language: "es"` selects the Spanish phonemizer instead of the English default. Leave it unset when using the official OpenAI API, which does not accept this parameter. When unset, nothing extra is sent.

Subject: [PATCH 032/240] feat: make the streaming TTS first-sentence threshold
 configurable (tts.streaming.min_len)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SentenceChunker hard-coded min_len=20 and all three construction sites
(gateway StreamingTTSConsumer, CLI/TUI stream_tts_to_speaker, dashboard
/api/audio/speak-stream) called SentenceChunker() with no arguments, so a
short CJK opener ("记得，叫团团。", 7 chars) was always buffered behind the
second sentence, delaying the first audible audio by roughly one LLM
sentence in voice setups. Add tts.streaming.min_len (default 20, unchanged
behaviour) to DEFAULT_CONFIG and a SentenceChunker.from_config(tts_config)
constructor that every construction site now uses, so the knob applies
identically on every speech surface. Invalid values keep the default; 0
floors to 1 so chunking cannot be disabled by accident.

Slim redo of PR #96933 by @liuhao1024 (added a second
first_sentence_min_chars key and per-emission state), credited as author.

Fixes #96927

Subject: [PATCH 033/240] fix(desktop): custom endpoints pin an API mode and
 keep /v1/models alias metadata
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Settings > Custom Endpoints assumed Chat Completions: the form, its types, the
update payload and _write_custom_endpoint carried no api_mode, so a
Responses-only (or Anthropic-compatible) host validated fine on /models and
then 404'd on every POST /chat/completions. Validation also flattened each
/v1/models row to a bare id, so a reasoning alias like gpt-5.6-sol-high
(canonical_model + reasoning_effort) was saved as a literal upstream model.

- Desktop form: API Mode segmented control (Auto-detect / Chat Completions /
  Responses API / Anthropic Messages — the same set `hermes model` offers);
  threaded through toPayload, hydrated from GET read-back.
- CustomEndpointUpdate.api_mode (Literal) persisted as providers.<id>.api_mode,
  the key the CLI writes and the runtime reads; None (older UI) leaves a
  hand-written mode alone, "" clears it. GET rows report api_mode.
- validate returns model_details (id / canonical_model / reasoning_effort)
  next to the unchanged string[] models; _parse_model_ids is now a projection
  of _parse_model_entries.
- Save keeps the alias metadata in providers.<id>.models and, when the picked
  default is an alias, persists the canonical model and pins its effort under
  agent.reasoning_overrides (the resolve_reasoning_config chokepoint).

 - **Providers settings pane** — a dedicated place to manage inference providers, with an Accounts / API-keys UX for signing in and storing credentials per provider. Accounts and API keys share the Settings **Applies to** selection: credential reads and edits, OAuth account removal, and sign-in launched here target the selected profile, not the active chat profile. The sign-in flow keeps that target through credential saving and model selection. Changing **Applies to** discards unsaved credential drafts. Closing sign-in cancels polling and ignores late results; a credential write already sent may still finish in its original profile. Externally managed CLI credentials use their own CLI and are not covered by this profile selector. Its **Local Models** view installs and manages an on-device llama.cpp runtime — see [Local Models](./local-models.md).
 - **Every provider and model in the menus** — the GUI surfaces the full provider list and every model that `hermes model` knows about, so you pick from the same catalog the CLI sees rather than a curated subset.
+- **Custom endpoints with an API mode** — **Settings → Providers → Custom Endpoints** has an **API Mode** selector (**Auto-detect**, **Chat Completions**, **Responses API**, **Anthropic Messages**) — the same choice `hermes model` offers for a custom provider. It is saved as `providers.<id>.api_mode` in `config.yaml`, so a Responses-only or Anthropic-compatible host is no longer called on `/chat/completions`. **Test** also keeps the alias metadata a gateway advertises in `/v1/models` (`canonical_model`, `reasoning_effort`): picking an alias such as `gpt-5.6-sol-high` saves the canonical model and pins its effort under `agent.reasoning_overrides`.
 - **xAI Grok OAuth** — Grok is a first-class OAuth provider in the launcher; sign in through the browser flow like the other OAuth providers.
 - **Tool-backend installs from the GUI** — run a tool backend's post-setup install steps directly from the app instead of dropping to a terminal. In the terminal backend picker, selecting a backend marked **Needs setup** asks for confirmation first; declining leaves the current backend selected.
 - **Terminal font picker** — choose an installed font in **Settings → Appearance**. Nerd Fonts such as `MesloLGS NF` render Powerlevel10k separators and icons in both interactive and agent terminals; the setting is saved per profile.

Subject: [PATCH 034/240] fix: auxiliary calls omit temperature up front for
 OpenAI reasoning families and remembered routes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

OpenAI's gpt-5.x / o-series accept only the default temperature and 400 with
`unsupported_value` on anything else. The auxiliary ladder already retried once
without the field, but every vision/title/compression call to such a model paid
a rejected round-trip first — and in #51083 the retry then timed out, so image
analysis failed outright with the 400 surfaced.

- `_fixed_temperature_for_model` now returns OMIT_TEMPERATURE for gpt-5.x
  (snapshots, -pro, -codex; gpt-5-chat excluded — it still accepts it) and
  o1/o3/o4, alongside the existing Kimi rule; the main-agent kwargs builder
  reads the same table.
- The temperature rung now `remember`s the rejecting route+model (same shape as
  the structured-output rung), so unknown relays/models pay the 400 once and
  every later call sends a single request.
- Tests that used gpt-5.x as the "model that still sends temperature" fixture
  moved to a neutral slug; two invariants added.

Live probe (fake OpenAI server that 400s on temperature != 1, real
async_call_llm task=vision): base 2 requests per call, every call; fixed
gpt-5.5 1 request; unknown model 2 then 1.

Fixes #51083
Salvages #51157 (@Tranquil-Flow) — superseded: gpt-5.5-only table entry
widened to the whole default-only class plus per-route memory.

Subject: [PATCH 035/240] fix(api-server): chained /v1/responses turns store
 each message once

_response_messages_turn_start_index compared the agent's result["messages"]
prefix against the API layer's bare {"role", "content"} dicts with whole-dict
equality. The agent's copies carry timestamp / _db_persisted (append_message)
and reasoning / finish_reason on assistant rows, so the check failed every
turn, turn_start fell to 0, and the fallback re-appended the full prior
transcript on top of itself: stored conversation_history grew 3 -> 8 -> 17
instead of 2 -> 4 -> 6, and that duplicated transcript was what the model was
replayed on the next turn.

Compare the prefix by what each message says (role, content, tool_calls,
tool_call_id) instead. The turn-only result shape and the compressed
transcript path are unchanged; a genuinely divergent transcript still falls
back to appending.

Fixes #95137
Fixes #101644
Refs #82513 (the doubling was the measured size driver; byte-capping stored tool
outputs is a separate design call since the stored history is replayed to the model)

Subject: [PATCH 036/240] fix(agent): rate-limit retry status names the
 provider's reset window
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

"⏱️ Rate limited. Waiting 60.0s (attempt 2/3)..." hid the one fact that
decides whether to wait or switch models: a per-minute throttle and a
13-minute plan window looked identical. The retry status and the terminal
"Rate limited after N retries" line now carry "Resets in ~13m" when the
error body/headers name a reset, derived from the same reset_at the
credential pool already parses (epoch s/ms, ISO-8601, Retry-After, free
text). Codex/ChatGPT usage-limit bodies that carry only the relative
resets_in_seconds now feed that reset_at as well.

One emit site (turn_recovery.compute_error_backoff /
max_retries_exhausted_result) serves the CLI, the messaging gateway, the
Ink TUI and Desktop through the status callback, so every surface gets the
hint.

Fixes #26889

has nothing to strip for that family; the walk's invariant (a 400 naming an
injected param triggers one retry without it) is pinned on gpt-4.1 instead.

Subject: [PATCH 039/240] fix(codex): allow Responses `text` through Codex
 preflight

_PREFLIGHT_ALLOWED_KEYS is derived from _PREFLIGHT_OPTIONAL_FIELDS and `text`
was not on that table, so any Responses request carrying `text.verbosity` (or
the structured-output `text.format` block) died inside Hermes with
"Codex Responses request has unsupported field(s): text." before reaching the
provider. One table entry both allows the key and passes it through
normalization like service_tier / context_management; empty or non-dict
values are dropped rather than rejected, matching the other optional fields.

Transport-level prerequisite for #20203. Salvaged from PR #103329 (test hunk
trimmed; invariant test lands in a separate commit).

Subject: [PATCH 040/240] fix: keep the Codex catalog fetch shape while capping
 -900k at max_context_window

Store the catalog's max_context_window in a parallel per-token dict populated
by the same fetch instead of widening the fetch's return tuple and versioning
the cache key ("v2:"), so the one external caller and every existing cache
reset keep working. The cap moves into _apply_verified_bump as
min(900K, live max): the bump still fires only for an opted-in -900k alias
whose advertised window is exactly 272K, 900K stays the offline/absent
fallback and a catalog max above 900K does not raise it.

Trim the salvaged tests to two invariants (parametrized alias cap incl. the
absent and above-cap controls; base slug never inherits the max) and document
the live-catalog cap next to the -900k opt-in.

Subject: [PATCH 041/240] feat(openai): agent.text_verbosity controls Responses
 answer length

New config key `agent.text_verbosity` ("" | low | medium | high, default ""
= not sent). When set, the Responses-family transport emits the top-level
`text: {"verbosity": ...}` field so GPT-5-family models can be asked for
terser or fuller final answers independently of reasoning effort (#20203).

Why this shape: the value is parsed once in agent_init._apply_agent_section
(unknown values warn and are ignored, so unset/"" can never flip the
provider default), passed to ResponsesApiTransport.build_kwargs like the
other per-request params, and never reaches chat_completions / Anthropic;
xAI's /responses is skipped the same way service_tier is. An explicit
request_overrides["text"] (e.g. structured-output format) still wins because
overrides merge after it. The Codex preflight whitelist entry that lets the
field through landed in the previous commit.

DEFAULT_CONFIG entry + docs row under Reasoning Effort.

Salvaged from PR #20258 (config key, docs and adapter direction); the
separate agent/text_verbosity.py module, constructor kwarg and the
cli/gateway/cron/tui_gateway plumbing were dropped in favour of the existing
agent-section config seam.

 emission and preflight

Two invariant tests (both red on origin/main @ 8df0a03):
- transport: text_verbosity="low" -> body text={"verbosity":"low"}; None/""
  -> no `text`; xAI Responses never gets it; chat_completions never emits it.
- preflight: `text` block passes the Codex whitelist; an empty block is
  dropped rather than rejected. (#20203)

Subject: [PATCH 043/240] feat(api-server): opt-in cap on tool outputs in the
 stored /v1/responses history

The persisted conversation_history snapshot embeds the cumulative transcript
with every tool output verbatim, so a few large tool outputs made a single
response_store.db write ~677 KB (2.7x the configured rotation threshold)
while the response.completed payload for the same turn was already trimmed.

Add gateway.api_server.history_tool_output_max_chars (default 0 = store
verbatim, current behaviour). When set, tool rows and string tool-call
arguments longer than N chars are cut to the head plus the same
"...[K more chars]" marker _trim_tool_items uses, in a copied row, before the
snapshot is stored; user/assistant text and the agent's own in-memory
transcript are untouched. Opt-in rather than default because the stored
history is exactly what the model is replayed on the next chained turn.

Live (200 KB tool output, temp HERMES_HOME): stored row 200,659 B off ->
4,681 B with the cap at 4000.

 The API server limits how many agent runs may execute at once across the endpoints that start one directly: the OpenAI-compatible endpoints, the Runs endpoints, and the session-chat endpoints (`POST /api/sessions/{id}/chat` and its `/stream` variant, which carry cross-machine agent DMs). Cron-triggered runs (`POST /api/jobs/{id}/run`, `POST /api/cron/fire`) go through the cron scheduler and are governed by cron's own limits, not this cap. The cap is read from `gateway.api_server.max_concurrent_runs` (default **10**; `0` disables the limit, negative values clamp to 0).

+### Stored history size for `previous_response_id` chaining
+
+Each stored `/v1/responses` snapshot embeds the full cumulative conversation history (that is what `previous_response_id` and `conversation` chaining replay), including every tool output verbatim. A conversation with a few large tool outputs can therefore make a single `response_store.db` write several hundred KB. Set `gateway.api_server.history_tool_output_max_chars` (default **0** = store verbatim) to cap each tool output and each string tool-call argument in the **stored** history at that many characters; anything longer is cut to the head plus a `...[N more chars]` marker. User and assistant text is never touched, and the `response.completed` payload and incremental SSE events are unaffected. Because the stored history is what the model sees on the next chained turn, enabling the cap also trims what the model is replayed — leave it at 0 if your workflow needs complete tool outputs across turns.

Subject: [PATCH 044/240] test(desktop): onboarding persists the resolved local
 endpoint URL (#65488)

Adds a vitest case for saveOnboardingLocalEndpoint that mocks
/api/providers/validate answering with `resolved_base_url` set to the
`/v1` variant of a bare host root typed by the user, and asserts the
subsequent /api/model/set body carries that resolved URL rather than the
URL as typed. This guards the salvaged #65489 behaviour that Save stores
the base that actually served /models, since the runtime POSTs
{base_url}/chat/completions verbatim and a host root that only
"detected" via /v1/models would 404 every chat.

Subject: [PATCH 045/240] fix(cli): a resumed opencode-go session re-derives
 its wire format from the stored model
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The classic CLI (`hermes --resume`, mid-chat `/resume`, oneshot resume) read the
session row's persisted api_mode/base_url verbatim in stored_session_route(), so
a row written while the session ran an anthropic_messages model on opencode-go
(MiniMax) pinned that wire onto a chat_completions model such as
deepseek-v4-flash-vision-exp after the model column moved. This is the CLI twin
of the tui_gateway _rederive_per_model_route() fix already on this branch: for
providers that pick the wire per model (model_derived_api_mode() is not None)
the route follows the stored model and the relay URL is healed; fixed-wire
providers keep honoring their row.

Probe (direct call of _restore_session_model on the PR head, no network): a row
with provider opencode-go, base_url '' and api_mode anthropic_messages for
deepseek-v4-flash-vision-exp resumed on the Go relay (never api.anthropic.com —
the empty base_url is re-resolved to https://opencode.ai/zen/go/v1 on both the
same-provider and provider-changed paths) but with api_mode anthropic_messages;
after: chat_completions on the same relay.

Docs: the OpenCode paragraph in providers.md now states both behaviours users
can observe from #96066 — per-model routing survives resume, and `*-vision*`
OpenCode ids attach images natively without a supports_vision override.

Part of #96066

OpenCode models whose id carries a `-vision` marker (for example `deepseek-v4-flash-vision-exp`) are treated as vision-capable even before models.dev lists them, so `agent.image_input_mode: auto` attaches images natively without a `supports_vision` override.

Subject: [PATCH 046/240] feat(api-server): reasoning on non-streaming replies;
 echoed reasoning input items are ignored
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to the streaming reasoning commit for #99552 covering the atoms it left open:

- Non-streaming `/v1/chat/completions` returns the turn's reasoning as
  `choices[0].message.reasoning_content`; non-streaming `/v1/responses` emits a
  completed `reasoning` output item ahead of the message (and ahead of that step's
  `function_call` items), so `GET /v1/responses/{id}` replays it too. The text is read
  from the assistant messages the agent already persisted (`build_assistant_message`
  stores it under `reasoning`) instead of re-accumulating `reasoning_callback` deltas:
  in non-stream mode the agent fires the callback per provider delta AND once more with
  the full text as the post-response fallback, so accumulating would double it.
- The Responses input parser skips `{type: "reasoning"}` items in `input` and
  `conversation_history`. Responses SDK clients replay a prior response's `output`
  list as the next `input`; before, the item became an empty `user` message (in
  `input`) or a 400 (in `conversation_history`).
- The streaming `response.completed` envelope carries the full reasoning item
  (`id`, `status: completed`) rather than a `{type, summary}` stub, matching the
  `output_item.done` item and the non-streaming shape.

Live (real route handlers, real AIAgent, fake OpenAI SSE model replaying
`delta.reasoning_content`): before — non-stream chat had no `reasoning_content`,
non-stream responses output was `[message]`, a chained turn echoing the output list
stored an empty user turn and the model saw a repaired placeholder; after — chat
`reasoning_content` equals the streamed text exactly, responses/GET output is
`[reasoning, message]`, the chained turn's model input is `[user, assistant, user]`.

The no-event TTFB watchdog on the Responses transport defaulted to 120s for
every endpoint, while the chat-completions siblings already raise the read
timeout and the stream stale detector for local servers. A local Qwen/DeepSeek
prefill on a large context legitimately runs past 120s, so the watchdog aborted
healthy requests ([WinError 10053] / connection aborted at exactly 120s).

When HERMES_CODEX_TTFB_TIMEOUT_SECONDS is unset and base_url is a local
endpoint, the TTFB default is raised to the local stale ceiling
(agent.local_stream_stale_timeout / HERMES_LOCAL_STREAM_STALE_TIMEOUT, 900s),
read through one shared helper also used by the stream stale detector. Hosted
endpoints and explicit env cutoffs are unchanged.

Salvaged from #92395; the run_agent.py reasoning-floor hunk is dropped.

Subject: [PATCH 048/240] test: local Responses TTFB grace invariants + timeout
 docs (#92302)

Two resolver invariants: a local endpoint left implicit resolves the first-event
watchdog to the local stale ceiling while a hosted URL keeps 120s, and an explicit
HERMES_CODEX_TTFB_TIMEOUT_SECONDS is honoured verbatim on local endpoints.
The API Timeouts table gains the Responses first-event watchdog row so the local
behaviour is documented next to the sibling timeouts.

 | Stale stream detection | 180s | Raised to a 900s ceiling (`agent.local_stream_stale_timeout`) | `HERMES_STREAM_STALE_TIMEOUT` |

+| Responses first-event watchdog | 120s | Raised to the 900s ceiling (`agent.local_stream_stale_timeout`) | `HERMES_CODEX_TTFB_TIMEOUT_SECONDS` |
 | API call (non-streaming) | 1800s | Unchanged | `providers.<id>.request_timeout_seconds` / `timeout_seconds` or `HERMES_API_TIMEOUT` |
 
 The **socket read timeout** controls how long httpx waits for the next chunk of data from the provider. Local LLMs can take minutes for prefill on large contexts before producing the first token, so Hermes raises this to 30 minutes when it detects a local endpoint. If you explicitly set `HERMES_STREAM_READ_TIMEOUT`, that value is always used regardless of endpoint detection.
 
 The **stale stream detection** kills connections that receive SSE keep-alive pings but no actual content. For local providers (which don't send keep-alive pings during prefill) the default is raised to a finite 900-second ceiling instead of the 180s base — configurable via `agent.local_stream_stale_timeout` or the `HERMES_LOCAL_STREAM_STALE_TIMEOUT` env var.
 
+The **Responses first-event watchdog** (Codex / `codex_responses` transport, including custom providers declared with the Responses transport) aborts and reconnects a request that accepts the connection but emits no stream event within 120 seconds. A local server prefilling a large context legitimately stays silent longer than that, so on local endpoints the implicit default is raised to the same ceiling as the stale stream detector (`agent.local_stream_stale_timeout` / `HERMES_LOCAL_STREAM_STALE_TIMEOUT`, 900s). An explicit `HERMES_CODEX_TTFB_TIMEOUT_SECONDS` is always used as-is (`0` disables the watchdog).
+
 The **stale non-stream detection** kills non-streaming calls that produce no response for too long. By default Hermes disables this on local endpoints to avoid false positives during long prefills. If you explicitly set `providers.<id>.stale_timeout_seconds`, `providers.<id>.models.<model>.stale_timeout_seconds`, or `HERMES_API_CALL_STALE_TIMEOUT`, that explicit value is honored even on local endpoints.
 
 This budget bounds every non-streaming call. A provider that accepts a request and then goes silent — connection held open, no bytes, no error — is aborted at the stale timeout and retried, rather than hanging until the much longer socket read timeout (or, for an unattended cron run, until something external kills the process).

Subject: [PATCH 050/240] test: trim Astra OAuth compaction test to the gate
 invariant

Drop the AIAgent-constructing parametrized test from the salvaged #103718 commit:
the safety gates it exercises (opt-in flag, compression_enabled, checkpoint
required, resolved-False runtime capability) are already pinned by
tests/agent/test_native_compaction*.py and the full-agent construction is the
slow, brittle half. Keep one parametrized gate test that proves capability and
per-request gate agree for exact gpt-6-astra on official Codex OAuth and stay
False on direct API, relays, look-alike hosts, http, and other GPT-6 variants.

Subject: [PATCH 052/240] fix(api-server): wire interim_assistant_callback;
 session SSE emits assistant.commentary

APIServerAdapter._create_agent / _run_agent never accepted an
interim_assistant_callback, so Codex phase="commentary" preambles and
other mid-turn assistant text were produced by the agent and dropped at
the API-server boundary; streaming clients saw only tool events and the
final answer (#67580).

Forward the callback into AIAgent and emit a typed `assistant.commentary`
event ({message_id, text, already_streamed}) on
POST /api/sessions/{id}/chat/stream, separate from assistant.delta and
never concatenated into assistant.completed.

Hand-reapplied onto the current facade layout from #67613.

Subject: [PATCH 053/240] fix(api-server): /v1/responses stream carries
 commentary as a phase-tagged message item
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Codex phase="commentary" progress (and any mid-turn assistant text) is
emitted on POST /v1/responses stream=true as its own completed
`message` output item with `"phase": "commentary"` — added/done pair,
listed in response.completed output — and kept out of the final answer
item so clients can render live progress without polluting the final
text (#67580). Text the agent already streamed as output_text.delta is
not re-emitted.

Hand-reapplied from #67593 onto the _ResponsesStream emitter.

Subject: [PATCH 054/240] fix(codex): superseded streams keep consuming so the
 final text is not truncated

When a newer attempt claimed the stream-writer slot, run_codex_stream's
accept_chunk hook returned False and Relay stopped consuming the Codex
Responses stream. The assembler then returned a "completed" response
holding only the text seen so far, and the gateway delivered a reply cut
mid-sentence (#69486) even with display streaming disabled.

Supersession now fences only the live callbacks (text and reasoning
deltas, commentary, first-delta) through the attempt's writer token and
consumption continues to the terminal frame, so the assembled final
response is complete. The single-writer invariant still holds: a
superseded attempt never writes into the live display. Request
retirement (watchdog kill) is unchanged and still stops the worker.

Ported from PR #69502 onto the Relay-backed stream path.

Fixes #69486

Subject: [PATCH 055/240] test(codex): pin complete final assembly when a Codex
 stream is superseded

Two invariant tests on the Relay-backed run_codex_stream path, red on
main: a superseded stream still yields the complete final text while
its live text/reasoning deltas, commentary and first-delta callbacks are
suppressed. Adds the contributor email mapping for the salvaged commit.

Subject: [PATCH 056/240] fix: parse Azure output-cap rejection wording
 (#78405)

Azure OpenAI rejects an over-cap request with "max_tokens is too large: N. This model
supports at most M completion tokens." Neither output-cap gate recognized it, so the
400 was routed into context compression, which cannot help (the input already fits)
and ended a fresh session with "cannot be shrunk further". Both gates now match the
phrasing and the advertised ceiling M becomes the retry budget.

Slimmed salvage of #81289.

Subject: [PATCH 057/240] fix: parse SGLang output-cap rejection wording
 (#83521)

SGLang states the window, the input and the completion figures explicitly ("maximum
context length of W tokens ... I tokens from the input messages and C tokens for the
completion") without ever naming max_tokens, so the 400 fell into compression instead
of a retry with a smaller completion budget. Available output = W - I; when I >= W the
wording describes a genuine input overflow and keeps routing to compression.

Slimmed salvage of #83558.

Subject: [PATCH 058/240] fix(api-server): /v1/runs emits message.interim;
 display.interim_assistant_messages gates all surfaces
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

POST /v1/runs + GET /v1/runs/{id}/events now carries mid-turn assistant
commentary as `message.interim` {text, already_streamed} — the same
contract the TUI gateway emits — so Runs clients can tell an active,
tool-heavy Codex turn from a stalled one instead of seeing only tool.*
events until run.completed (#67580).

APIServerAdapter._create_agent applies the same
`display.interim_assistant_messages` gate the messaging gateway and the
TUI apply (resolve_display_setting, per-platform override honoured):
when off, no callback is installed and nothing leaves the agent on any
of the three streaming surfaces. Dedup of repeated commentary stays in
agent/stream_delivery.py, where every surface already relies on it.

Tests: /v1/runs event contract; session SSE + /v1/responses item shape
plus the display gate (both red on the base commit). Docs: event
payloads on all three surfaces.

Subject: [PATCH 059/240] fix: output-cap failure copy stops pointing at the
 removed model.max_tokens key
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

fd3565deecb removed every user-facing output-cap control, but the unparseable
output-cap failure in agent/turn_overflow.py::_recover_context_length still told users
to "Lower model.max_tokens in config.yaml" — a key Hermes no longer reads. The notice
now explains what happened (the provider's cap was exceeded and the error did not
state the limit) and where the cap actually lives (the endpoint's default max output
tokens on the server or proxy) without naming a config key that does not exist.

Tests: one parametrized invariant for the Azure and SGLang ceiling wordings plus the
SGLang input-alone-over-window control (red on base).

Subject: [PATCH 061/240] fix: Codex CLI recovery no longer replaces a
 credential from another workspace

Automatic recovery from ~/.codex/auth.json saved the imported pair blindly.
A Codex Desktop/CLI login into a different ChatGPT workspace (same OpenAI
user) therefore silently replaced the Hermes credential being repaired, and
the pool aliases synced with it, so both pool slots pointed at the other
workspace while labels and order looked unchanged (#73667). The save also
raced an explicit re-auth landing between the failed read and the write.

Thread the access_token the caller observed (None on the missing-token path)
into _recover_codex_tokens_from_cli. Under _provider_state_transaction the
save is a compare-and-swap: skip when the stored token no longer equals the
observed one (a concurrent re-auth wins), refuse with a redacted warning and
a relogin hint when the observed and imported tokens carry a different known
principal (agent/credential_pool._codex_principal_identity), else persist.
Unknown identity on either side keeps today's repair behaviour.

Salvage of #73677 (@Tranquil-Flow), reworked per review: the identity guard
and the caller-observed CAS are kept; the second unlocked observation helper
and the 11-test suite are replaced by two invariant tests.

Subject: [PATCH 062/240] feat: slim the per-provider session header to the
 route seam and document it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Trim of the cherry-picked #104566 so it clears the salvage bar and covers #86241:

- The config getter matches entries the way every sibling per-provider knob does
  (`_entries_for_route`, route identity only) instead of a second provider-name axis;
  returns "" like `get_custom_provider_extra_headers` returns {}.
- `merge_opencode_session_headers` becomes `merge_session_affinity_headers` at both
  call sites (main `build_api_kwargs`, auxiliary `_build_call_kwargs`); the alias line
  is gone. Both sources merge (an OpenCode target that also declares a header gets both).
- Tests cut from six to two invariants: configured header carries one value per
  conversation on chat_completions, anthropic_messages and auxiliary kwargs (different
  for another session, caller-pinned wins); unconfigured → no header on any path.
- Docs: `configuring-models.md` per-provider options, `providers.md` entry key list,
  `cli-config.yaml.example` — the key is opt-in, default off, so DEFAULT_CONFIG is unchanged.

Why: a session-aware proxy classifies a request with no session id whose last message is a
tool_result as a NEW conversation and re-sends the whole history upstream (cache_write ≈
cache_read). Hermes already derives a rotation-stable conversation key for OpenCode; naming
the header per provider lets any proxy receive it without shipping an identifier by default.

 Header values routinely carry credentials — Hermes never logs them. `extra_headers` applies to OpenAI-compatible routes; the `anthropic_messages` and `bedrock_converse` API modes do not use it.

Off unless set — Hermes never sends a session identifier to an endpoint that did not ask for one. Session-aware proxies fronting a stateful backend (LiteLLM's `x-litellm-session-id`, self-hosted Claude/OpenAI gateways) otherwise have nothing to correlate an agent loop on and treat nearly every request as a new conversation, re-sending the whole history upstream on each turn. The value is opaque, stable across the turns of one conversation (including compaction), and different for every conversation:

 **`discover_models`** — set to `false` (default `true`) to skip querying the endpoint's `/models` listing and use only the `models` you configured on the entry. Handy for gateways whose model listing is slow, unreliable, or noisy:

Subject: [PATCH 063/240] feat(codex): named custom providers work with the
 codex_app_server runtime

`model.openai_runtime: codex_app_server` only ever admitted `openai` /
`openai-codex`: a named custom provider (`providers.<name>`) resolves to
provider="custom" on the named-custom ladder rung, which never ran the
runtime gate, so `/codex-runtime codex_app_server` silently left the main
turn on Hermes' chat-completions client. And even when routed, thread/start
sent only `cwd`, so codex could not know which of its own providers to use.

- `_maybe_apply_codex_app_server_runtime` takes `requested_provider` and
  admits provider="custom" only when `codex_model_provider_id()` finds a
  configured `providers.<name>` entry (bare `custom`, ollama/vllm aliases
  and unknown names have no stable id -> ineligible, unchanged).
- The named-custom rung applies the same opt-in the pool rung already does
  for openai/openai-codex.
- `CodexAppServerSession(model=, model_provider=)` -> `thread/start.model` /
  `.modelProvider` (fields verified against the codex 0.147 app-server
  schema). `_ensure_codex_session` fills them only for custom agents; codex
  resolves base_url/env_key from its own `[model_providers.<name>]`, so the
  Hermes credential never enters the JSON-RPC payload.
- `tui_gateway/server.py::_make_agent` forwards `requested_provider` so the
  Desktop/TUI agent knows the provider id (it otherwise collapses to
  "custom" and codex would fall back to its default provider).
- Docs: matching `[model_providers.<name>]` + `env_key` requirement and the
  bare-`custom` ineligibility.

Ported and trimmed from #75191 by @cosin2077 (aux-loop `allow_codex_app_server`
plumbing, `cli-config.yaml.example` block and the integration-test suite dropped:
background_review already maps codex_app_server -> codex_responses on main).

Fixes #75186

Flags: `--global` persists the change to config.yaml; `--session` forces session-only; `--once` applies to the next turn only; `--refresh` re-fetches the provider's model list; `--provider <name>` switches backend (session-only unless `--global`); `--reasoning <level>` sets the reasoning effort (`none`, `minimal` … `ultra`) in the same step and with the same scope as the pick. A plain `/model <name>` is session-only unless `model.persist_switch_by_default: true` is set — except when no `model.default`/`model.provider` is configured yet, in which case the first pick persists so the profile gets a real default. The same rule governs the desktop composer picker. **Interactive picker:** running `/model` with no arguments opens the provider→model picker; on the model list you can **type to fuzzy-filter** the models (e.g. type `grok` to narrow to matching models), Backspace to trim the filter, Esc to clear it (or close the picker). Selection always resolves to one concrete model — the filter only narrows the list, it never guesses. After the model, a third step offers the reasoning effort for that model (or **Keep current effort**); it is skipped when the catalog says the route has no reasoning control. **Note:** `/model` can only switch between already-configured providers. To add a new provider, exit the session and run `hermes model` from your terminal. **Cost note:** switching models mid-conversation resets the prompt cache — the cache key includes the model, so your next turn re-reads the entire conversation at full input price instead of the ~75%-discounted cached rate.

Auxiliary calls (titles, compression, memory review) still use Hermes' own `providers.my-gateway` entry.
+
+   Caveats: the name after `custom:` is the `providers:` config key and must match the `[model_providers.<name>]` table name exactly — if it does not exist on the codex side, codex reports an unknown provider rather than silently using the Hermes endpoint. Anonymous `provider: custom` (a bare `base_url`) is not eligible: it has no stable name to hand to codex, so it stays on Hermes' standard runtime.

Subject: [PATCH 064/240] test(codex): pin named-custom routing and
 thread/start provider selection

Two invariants, both red on 8df0a037: the resolver routes a configured
`providers.<name>` entry to codex_app_server only under the opt-in (bare
`custom` and the no-opt-in case stay on chat_completions), and the session
built by `_ensure_codex_session` sends `model` + `modelProvider=<name>` on
thread/start without the API key while openai-codex / bare custom agents
keep `cwd` only.

Subject: [PATCH 065/240] fix(api-server): pin the reasoning_callback wiring
 through _spawn_stream_agent/_run_agent/_create_agent

Replace the direct-queue chat-completions test with one that drives
_spawn_stream_agent with the real _run_agent/_create_agent path and a fake
AIAgent invoking reasoning_callback, asserting the delta.reasoning_content
frame reaches the SSE writer. Unwiring either the _spawn_stream_agent kwarg
or the AIAgent kwarg now fails the test.

Subject: [PATCH 067/240] fix: pin the cross-protocol nudge strip through the
 production request path

The wire test called drop_thinking_only_and_merge_users directly, so deleting the
drop_nudge_marker kwarg in turn_request_assembly.assemble_api_request left it green.
Replace it with a run_conversation-driven test whose fallback stub flips api_mode to
chat_completions and asserts the captured request carries no nudge fragment, no
codex_reasoning_items and alternating roles (red with the kwarg removed). File is back to
two tests.

Subject: [PATCH 069/240] fix: close the raw provider stream when the
 post-terminal drain times out under a Relay-managed wrapper

On the Relay-managed path ManagedLlmStream.close() cannot reach the provider
response while the loop is still running the drain (RuntimeError, swallowed by
_close_event_stream), so the httpx response and drain thread lingered until the
socket read timeout. Capture the raw stream in _codex_stream_created and close it
too on drain timeout; the unmanaged path is unchanged (idempotent double close).

Subject: [PATCH 070/240] fix(acp): only the switch_model rejection maps
 session/set_model to invalid params

The `except ValueError` in set_session_model wrapped both the switch_model rejection and
the _make_agent rebuild, so a rebuild ValueError (provider disabled in config, context
window below the floor) was reported as -32602 by accident. _switch_model now raises a
dedicated ModelRejected(ValueError) at the rejection site and set_session_model catches
only that; rebuild ValueErrors keep the -32603 internal-error path. The slash /model path
still sees the rejection text via str(exc).

Subject: [PATCH 072/240] fix: parse the "limited to N" output-cap figure so
 the budget steps down

is_output_cap_error already classified "max_completion_tokens is limited to
16384 for glm-5.2" as an output cap, but parse_available_output_tokens_from_error
returned None, so _recover_context_length failed fast instead of clamping.
Add the ("limited to",) signal and the direct-cap regex; the Scaleway string
now yields 16384. Also document model.key_env in the custom provider block.

Subject: [PATCH 073/240] fix(oneshot): pin the resumed opencode-go wire
 re-derivation on the oneshot resume entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

stored_session_route() already re-derives api_mode/base_url from the stored model for
per-model-wire providers (CLI twin fix), and _apply_stored_session_runtime consumes it;
this adds the test that drives the oneshot production entry so a regression on that
surface (row with anthropic_messages + /v1-stripped Go relay for a chat_completions
model) goes red — verified red with the shared-helper hunk reverted, green with it.

Subject: [PATCH 074/240] fix(gateway): heal a persisted opencode relay URL on
 /model override rehydration; share the per-model api_mode lookup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- gateway/run_agent_cache.py::_rehydrate_session_model_override re-resolved api_mode from the
  target model but kept the persisted base_url verbatim, so a /v1-stripped or other-family
  relay URL written by an older build stayed on a chat_completions model. Run
  normalize_opencode_base_url after re-resolution for opencode-family providers (test drives
  the production rehydration entry: red before, green after).
- hermes_cli/model_switch.py::_build_switch_result now uses model_derived_api_mode() instead
  of its own exact-key table lookup, so a custom provider extending a family slug
  (opencode-go-bridge) gets the same per-model wire on live /model as on resume.
- tui_gateway/server.py::_resolve_agent_model_runtime: the re-derivation guard is
  any(overrides.values()) — a model_override dict always carries the three keys, so
  'if overrides' was always true.

Subject: [PATCH 075/240] fix(auth): read-only Codex reads take no store lock;
 /model picker never refreshes

The expiring-singleton status test never reached the singleton resolver:
`load_pool("openai-codex")` mirrors the singleton as a `device_code` pool
entry, so with a still-valid token `pool.peek` answered and the
`get_codex_auth_status()` wiring under test was never exercised (the test
stayed green with `resolve=` reverted). The token is now already expired,
the status result is asserted to come from `hermes-auth-store`, and the
`read_only` beats `force_refresh` call is a secondary assertion on the
resolver itself.

`resolve_codex_runtime_credentials(read_only=True)` reads the store without
`_auth_store_lock`: `_save_auth_store` replaces auth.json atomically, so a
lock-free read never sees a torn file, and materialising `auth.lock` is
itself a write a diagnostic must not make (#68004). Once the pool has
mirrored the singleton a status read leaves the HERMES_HOME manifest
byte-identical.

`_codex_catalog` (the `/model` picker) now reports the stored login
read-only, matching the intent stated on `read_only`; an expired stored
token yields the hardcoded catalog until the runtime lease refreshes it.

Subject: [PATCH 076/240] fix: drop the redundant _request_is_current() from
 the first-event stamp guard

_on_event is only ever installed as on_event=_fenced(_on_event), and _fenced
already refuses every call once the request is retired, so the inner predicate
could never be false when reached. Comment now points at the fence.

Subject: [PATCH 077/240] fix(gateway): reset the pre-agent fallback notice
 stash on every resolution; pin it at the turn-runner entry

_resolve_session_agent_runtime stashed the notice on the shared runner attribute and only
overwrote it on the default-runtime path: the /model-override fast path returned before the pop,
and the hygiene/inbound/slash callers set it with no consumer, so a stale notice from another
resolution could attach to the next override-session turn. Reset the stash at the top so every
exit path starts clean.

Replace the helper-only test with one that drives the production entry point (the real
_resolve_session_agent_runtime bound to the runner + TurnRunner.run_sync with AIAgent stubbed):
it goes red when either the run_turn.py pop or the run_turn_runner attach is removed, and asserts
'_fallback_notice' never reaches the AIAgent kwargs. Second test pins the fast-path reset.

Subject: [PATCH 078/240] fix(agent): key the temperature route memory on the
 same base_url the kwargs builder reads

_build_call_kwargs looked the rejected-route memory up under
base_info or resolved_base_url, but the parameter rung recorded it under
route.base_info alone, so a client with no base_url on a task that resolved
one never hit the memory and paid the 400 on every call. Record with the
same effective value.

Subject: [PATCH 079/240] fix: drop the reasoning fields when the route rejects
 an enabled reasoning level
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A structured reasoning-field 400 on an ENABLED config (#100536:
`reasoning.effort: max` on a Responses relay) reached the
reasoning_mandatory rung, which only knows how to drop a disable: for an
enabled config _reasoning_config_for_wire returned the config unchanged,
so the one-shot retry resent the identical request (a guaranteed second
400) under a notice that blamed 'disabling reasoning'.

Record what the wire builder actually sent (agent._wire_reasoning_config)
and, when the rejected request carried an enabled effort, omit the
reasoning fields for the rest of the session — the route default, as the
auxiliary ladder's _without_reasoning_fields already does — under a
'rejects reasoning effort <x>' notice. A rejected disable keeps the
existing contract: the user's own config goes out verbatim on the retry.

Test drives classify_api_error -> recover_after_classification ->
_build_api_kwargs_for_mode and asserts the retry's reasoning_config is
None; control keeps the disable copy and the verbatim resend.

Subject: [PATCH 080/240] test: drive the auxiliary strip-and-retry rung with
 the structured reasoning-field 400
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the direct _is_reasoning_field_rejection predicate test with one
that runs _call_fallback_candidate_sync against a client returning the
message-less structured body (#100536) and asserts the retry goes out
without reasoning_effort — unwiring the structured match from the
classifier now turns this test red.

Subject: [PATCH 081/240] fix(codex_app_server): retire the thread when the
 composed prompt changes mid-session

_ensure_codex_session records the developerInstructions composition it sent; when the
TUI/Desktop gateway mutates the live agent's prompt in place (/personality, prompt
mirror) the next turn closes the stale thread and starts one carrying the new prompt,
matching what the standard loop applies on its next API call. Sessions attached
without a recorded composition are kept. Docs sentence updated.

@@ -410,7 +410,7 @@ Known limitations:
 - **Hermes auth and codex auth are separate sessions.** You need both `codex login` AND `hermes auth add openai-codex` for the cleanest UX (the runtime uses codex's session for the LLM call). This is a deliberate design choice in Hermes' `_import_codex_cli_tokens` — Hermes won't share OAuth state with codex CLI to avoid clobbering each other on token refresh.
 - **`delegate_task`, `memory`, `session_search`, `todo` are unavailable on this runtime.** They need the running AIAgent context which a stateless MCP callback can't provide. Use `/codex-runtime auto` when you need these.
 - **No inline patch preview in approval prompts when codex doesn't track the changeset.** Codex's `fileChange` approval params don't always carry the changeset. Hermes caches the data from the corresponding `item/started` notification when possible, but if approval arrives before the item has streamed, the prompt falls back to whatever `reason` codex provides.
-- **Conversation history is not projected into the codex thread.** The codex thread receives Hermes' system prompt when it starts plus each new user message; prior Hermes history (e.g. from a resumed session) is not replayed into it. Prompt changes made mid-session apply when the thread is next (re)created.
+- **Conversation history is not projected into the codex thread.** The codex thread receives Hermes' system prompt when it starts plus each new user message; prior Hermes history (e.g. from a resumed session) is not replayed into it. When the composed prompt changes mid-session (for example `/personality` in the TUI or Desktop), the next turn retires the running thread and starts a new one carrying the updated prompt; that new thread does not inherit the retired thread's history.
 - **Sub-second cancellation isn't guaranteed.** Mid-stream interrupts (Ctrl+C while codex is responding) are sent via `turn/interrupt`, but if codex has already flushed the final message, you get the response anyway.
 
 If you find a bug, [open an issue](https://github.com/NousResearch/hermes-agent/issues) with the output of `hermes logs --since 5m`. Mention `codex-runtime` in the title so it's easy to triage.

Subject: [PATCH 082/240] fix(gateway): route AuthError fallback through
 resolve_runtime_with_fallback

The gateway kept its own get_fallback_chain walk in _try_resolve_fallback_provider,
a near copy of the shared resolution-time helper. _resolve_runtime_agent_kwargs now
calls resolve_runtime_with_fallback(cfg) and the private loop is deleted; the
rate-limited (429) vs auth-failed log distinction (is_rate_limited_auth_error) moves
into the helper so every caller keeps it.

Also: drop the test-only resolve= seam from the helper (tests monkeypatch
hermes_cli.runtime_provider.resolve_runtime_provider instead), and log non-AuthError
fallback-entry failures at warning so a mistyped fallback provider is not silently
skipped at debug level.

Tests: test_fallback_chain_runtime_uses_the_entry_model now drives
gateway.run._resolve_runtime_agent_kwargs (red when the helper's chain walk is
sabotaged); two gateway stubs accept the helper's keyword arguments.

Subject: [PATCH 083/240] fix(agent): live retry wait line and vendor reset
 headers carry the reset window
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The enriched "Rate limited. Resets in ~13m. Waiting ..." text only lived in
the buffered status, which replays solely when every retry fails. The line a
user actually watches during the wait — _emit_diagnostic_wait on CLI, the
messaging gateway, the Ink TUI and Desktop — was still the anonymous
"waiting on provider — retrying in 60s". It now reads "rate limited — resets
in ~13m, retrying in 60s (attempt 2/3)" when the reset is known and keeps the
old wording otherwise.

extract_api_error_context also learns the per-bucket reset headers plain
OpenAI 429s (x-ratelimit-reset-requests/-tokens, "6m0s"/"1.5s"/"20ms") and
Anthropic 429s (anthropic-ratelimit-*-reset, ISO-8601) carry when no
Retry-After is present, at the lowest priority after Retry-After and
x-ratelimit-reset; past timestamps are ignored.

The websocket sent {type:'start', sample_rate} right after resolving the
streamer, but the OpenAI-compatible streamer only learns the endpoint's real
PCM rate from the response headers inside stream(). Desktop/dashboard open
their AudioContext at the start frame's rate, so a 44.1 kHz endpoint still
played at half speed there while the CLI speaker was already correct.

Defer the start frame until the first PCM chunk (or end-of-speech when the
stream is empty) so the rate is final when the client reads it. The client
sends text on open without waiting for start, so no client change is needed.

Subject: [PATCH 085/240] fix(tests): split the bundled OpenAI sample-rate test
 into single-invariant cases

The WAV playback test also asserted the static config expectation, the bogus
config fallback and two header-parse cases. Move those into one parametrized
resolution test so each failure names its own invariant.

Subject: [PATCH 086/240] fix: pin tts.streaming.min_len at the speaker and
 speak-stream entry points

The reviewer found that only the gateway consumer wiring was covered:
reverting hermes_cli/web_routers/audio.py::speak_stream_ws and
tools/tts_tool_speaker.py::stream_tts_to_speaker to a bare
SentenceChunker() left every test green. Replace the direct
SentenceChunker.from_config() unit test with two tests that drive the
production entry points (the WebSocket handler through the ASGI test
client, the CLI/TUI speaker through stream_tts_to_speaker) with
tts.streaming.min_len = 6 and assert a 7-char CJK opener reaches the
provider as its own request. Both go red when either call site drops
back to SentenceChunker().

Subject: [PATCH 088/240] fix: surface the pre-agent provider fallback on the
 TUI/Desktop gateway and cron too
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The same credential-resolution fallback the messaging gateway now announces also runs in
tui_gateway/server.py (_resolve_runtime_with_fallback, used_fallback=True only logged 'Primary
auth failed, falling back to ...') and in cron/scheduler.py (_resolve_job_runtime, 'fallback
resolved to ...'), with no user-visible notice on either surface.

- hermes_cli/fallback_config.pre_agent_fallback_notice: shared text builder (gateway/run.py now
  calls it) so the three pre-agent paths cannot drift in wording.
- TUI/Desktop: _resolve_agent_model_runtime tags the fallback runtime; _make_agent pops the tag
  and sets agent._pending_fallback_notice, emitted once via status_callback on the first reply.
- cron: _resolve_job_runtime tags the runtime; the setup pops it and run_job prepends the notice
  to a deliverable final_response ([SILENT] and the [CRON_FAILURE] first-line marker keep their
  contracts) — a cron agent has no status rail, so the report is the only place it can surface.

Tests drive the production entry points (_make_agent, run_job) with the resolver and AIAgent
stubbed; each goes red with its attach/prepend removed.

Subject: [PATCH 089/240] fix(dashboard): a typed-root 404 no longer hides the
 /v1 key rejection; pin the Settings Test URL rewrite

_probe_openai_compatible_models kept the FIRST failure, so a server that lives at /v1 and
wants a key (root 404, /v1/models 401) reported 'HTTP 404' instead of 'rejected the API key'.
A later non-success now replaces a retained 404 and is reported against the candidate that
produced it. Also adds the Settings vitest: after Test the URL input shows the base that
actually served /models, so deleting the form rewrite goes red (#65488).

Subject: [PATCH 090/240] fix: honour tts.streaming.min_len on the Desktop
 client-direct TTS path

The Desktop's client-direct playback (first rung of the ladder, ahead of
the /api/audio/speak-stream relay) has its own sentence cutter with a
hard-coded 24-char floor, so a short CJK opener was still buffered there
although the PR promised the knob on every surface. GET
/api/audio/voice-config now carries the resolved tts.streaming.min_len
in the direct TTS block (tools/voice_client_config.py), and
openClientDirectSpeechSession passes it to cutSentences; older backends
without the key keep the historical 24.

Tests: test_elevenlabs_tts_direct_carries_voice_and_model asserts the
field; one vitest asserts a 7-char CJK opener is cut alone at min_len 6
and rides with sentence two without the key. Both red before wiring.

Subject: [PATCH 091/240] fix(desktop): custom endpoint Test probes the
 transport route, not just /v1/models
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A Responses-only (or Anthropic-compatible) host lists models on GET /models and
then 404s every POST /chat/completions, so Test passed and the first chat
failed (#93622, item 2). validate_custom_endpoint now keeps the probe client
open and, after the models GET, POSTs a one-token request to the route of the
pinned api_mode — or of the mode the runtime's URL auto-detect resolves to
(_detect_api_mode_for_url, fallback chat_completions, the same order
runtime_provider_custom uses). 404/405/501 fails validation with a message that
names the transport and the route; 200/400/401/422/429 prove the route exists;
a network error or timeout stays inconclusive so a local server still loading
its model is not blocked. The response reports the mode it checked as
transport_checked; the Desktop success toast names it so an auto-detected mode
is visible before Save.

The Providers-pane OPENAI_BASE_URL probe returns model_details next to models
too, so an alias picked there keeps its canonical_model / reasoning_effort.

 - **Providers settings pane** — a dedicated place to manage inference providers, with an Accounts / API-keys UX for signing in and storing credentials per provider. Accounts and API keys share the Settings **Applies to** selection: credential reads and edits, OAuth account removal, and sign-in launched here target the selected profile, not the active chat profile. The sign-in flow keeps that target through credential saving and model selection. Changing **Applies to** discards unsaved credential drafts. Closing sign-in cancels polling and ignores late results; a credential write already sent may still finish in its original profile. Externally managed CLI credentials use their own CLI and are not covered by this profile selector. Its **Local Models** view installs and manages an on-device llama.cpp runtime — see [Local Models](./local-models.md).
 - **Every provider and model in the menus** — the GUI surfaces the full provider list and every model that `hermes model` knows about, so you pick from the same catalog the CLI sees rather than a curated subset.

Subject: [PATCH 092/240] fix: map the emails of the contributors #115851
 supersedes

#115851 reimplements the api_mode selector and alias metadata from #69824
(@SacrEllfarch), #82148 (@JackLee992) and #93693 (@fangliquanflq) in a
single-authored commit. Their Co-authored-by trailers ride on the follow-up
commit; these mapping files make the release changelog credit them.

Subject: [PATCH 093/240] feat(error-surface): 429 error card shows when the
 usage limit resets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A "HTTP 429: The usage limit has been reached" turn offered only Retry and
never said when a retry would work, so users guessed or babysat the app
(#98852). The provider already tells us: Retry-After / resets_at /
retry_after are parsed into the turn's error context (extract_api_error_context)
and honoured by the backoff, but the datum died there.

- agent/turn_recovery.py::_stamp_limit_reset: both terminal paths
  (max_retries_exhausted_result, nonretryable_client_error_result) stamp
  failure_resets_at (epoch s) on the failed result and append one plain line
  ("Limit resets at 14:05 (in 1h 00m).") to final_response, which every text
  surface (CLI, Ink TUI, messaging gateway) renders.
- agent/error_surface.py: result path forwards failure_resets_at as
  surface.resets_at; the exception path derives it from the same context.
- tui_gateway/contracts/events.py::ErrorSurface.resets_at + regenerated
  apps/shared gateway-contract outputs.
- apps/desktop lib/error-surface.ts: parse resets_at -> resetsAt,
  formatLimitReset("HH:mm (in 1h 05m)", null once passed), diagnostics line;
  the error card renders "Limit resets at …" next to Retry (i18n copy in every
  full locale).
- Docs: website/docs/user-guide/desktop.md error-card section.

Informational only: no scheduled or automatic retry is added — firing a turn
unattended on a subscription is the maintainer's call (#98872, #103048).

Subject: [PATCH 094/240] fix(tui_gateway,cli): per-turn fallback sync fails
 closed on a torn config; classic CLI syncs too (#95066)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review follow-up. `_sync_agent_fallback_with_config` read the chain through `_load_cfg()`, which
fails open to `{}` on a torn/invalid config.yaml — `get_fallback_chain({}) == []` then WIPED the
live agent's chain (the messaging gateway's `_refresh_fallback_model` keeps its last known-good
chain). The sync now reads `load_user_config_effective(fail_closed=True)` and skips the apply when
the read fails, so only a config that actually loaded can remove a chain.

The wiring test drives `_prepare_turn_input` (turn admission) instead of string-matching the
prompt_turn source, and covers removal and the active-fallback cooldown skip.

Sibling surface: the classic interactive CLI holds one long-lived agent and read the chain once in
`HermesCLI.__init__`; `HermesCLI.chat` now applies the same fail-closed per-turn sync (and refreshes
`self._fallback_model` so a rebuilt agent starts from the fresh chain). Docs table caveat added.

Subject: [PATCH 095/240] feat(web): add openai-native backend for Codex
 server-side web_search

Declares OpenAI's provider-executed Responses `web_search` built-in in place of
the client-side `web_search` function, mirroring the existing xAI native-search
path. Selected via `web.search_backend: openai-native`; search-only, so
`web_extract` keeps resolving to its own backend.

The Responses adapter already recognises built-in tool types
(`_RESPONSES_BUILTIN_TOOL_TYPES`) and preflight passes them through, so the only
missing piece was the swap itself plus a provider name for the config to point at.

Gating is deliberate: two-sided (Codex backend AND a selected openai-native
backend) and fail-closed, so a custom OpenAI-compatible endpoint or an
unresolved provider leaves the client tool untouched.

Subject: [PATCH 096/240] test(web): cover the openai-native swap, document the
 backend

Three invariants on the Codex transport: selected -> built-in declared and the
client web_search dropped (web_extract preserved); unselected -> untouched;
non-Codex -> untouched even when the backend says native.

Verified with a sabotage run: with the swap disabled the first test fails and
the two negative tests still pass.

Docs: backend table row plus an OpenAI Native section covering credentials,
transport scope, search-only behaviour, and the 1:1 (never additive) contract.

 Unlike index-backed providers (Brave, Tavily, Exa) which return verbatim search-engine results, xAI is an LLM choosing which URLs to surface and writing the titles and descriptions itself.

+### OpenAI Native (Codex Responses) {#openai-native}
+
+Declares OpenAI's provider-executed `web_search` tool on the Codex Responses endpoint (ChatGPT/Codex subscriptions). The model drives search server-side and folds the results into its own answer — Hermes never runs a client-side search in this mode.
+
+```yaml
+# ~/.hermes/config.yaml
+web:
+  search_backend: "openai-native"
+```
+
+Requirements and scope:
+
+- **Credentials**: an openai-codex OAuth login (`hermes auth --provider openai-codex`). This backend has no API key of its own; without a login it is simply unavailable.
+- **Transport**: only the Codex Responses endpoint exposes the built-in. On any other transport — a custom OpenAI-compatible `base_url`, or a non-OpenAI model — the client-side `web_search` function is left untouched, because the endpoint cannot be relied on to host the tool. Point `web.search_backend` at an ordinary provider for those.
+- **Search only**: the built-in covers search, not extraction. Pair it with Firecrawl (or another extract-capable backend) through `web.extract_backend` when you also need `web_extract`.
+
+**One tool either way.** Selecting this backend swaps the client-side `web_search` function for the built-in 1:1 — it is not an additive grant. A session whose toolset has no `web_search` never gets server-side search injected.

Subject: [PATCH 097/240] fix(web): openai-native backend docs name the real
 login command, English picker tag, registry test lists the plugin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Trim of the salvaged openai-native marker provider (#107377):
- `hermes auth --provider openai-codex` does not exist; the login command is
  `hermes auth add openai-codex` (hermes_cli/subcommands/auth.py). Fixed in
  plugin.yaml, provider.py docstring and the web-search docs (2 spots).
- `hermes tools` picker tag was Chinese; now English like every other provider.
- tests/plugins/web/test_web_search_provider_plugins.py enumerates the bundled
  registry exactly, so the new plugin made it fail; it now lists openai-native
  with capability flags (search=True, extract=False) — the search-only
  invariant that keeps web_extract on its own backend.
- contributors/emails mapping for the salvaged author.

Subject: [PATCH 098/240] fix(tests): pin the gateway identity inputs in the
 migrate fleet fixture

test_update_hook_migrates_when_unblocked_and_only_warns_when_blocked read
two HOST facts through the real guards: /proc/<fake pid> for the fleet's
made-up pids 4101/4102 and the user-scope systemd unit path under the real
$HOME. On a CI runner pid 4101 can be a live root-owned daemon, so
_guard_unix_user reported a "UNIX privilege boundary" and the hook printed
the blocker block instead of migrating (job 115840). The fixture now
resolves every fake live gateway to the fleet owner's uid and points the
user unit path into tmp_path, so the verdict depends only on the fixture.

A/B: base fails with CI's exact assertion under an emulated root-owned
/proc/4101; the pinned fixture passes the whole file under the same host.

Subject: [PATCH 099/240] fix(tests): idle-proof live test waits for the
 startup cron tick to drain

The Desktop child's HERMES_BACKEND_READY sentinel is printed while its
in-process cron ticker is still running its first tick, and that tick
holds retirement admission through the whole scan. On a loaded runner the
single /api/health/idle probe landed inside that window and saw
{idle: false, reason: turn_in_flight, detail: retirement_admission} on a
resident that was merely booting (jobs 115759/115801/115895 and earlier).

The test now polls the probe until the resident proves idle (bounded at
60 s) and until the busy child names the cron ledger, and asserts the busy
child never once claimed idle. Same invariant, no quiet-runner assumption.

Under 20 CPU burners + a parallel tests/agent/ run: base 2/10 failed with
CI's exact assertion, fixed 20/20 passed.

Subject: [PATCH 102/240] feat(desktop): 429 usage-limit card can schedule one
 retry for when the limit resets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 429 error card already tells the user when the limit lifts (#115924:
`Limit resets at HH:mm (in 1h 05m)`), but they still had to be at the
keyboard at that moment to press Retry (#98852). The card now also offers
ONE `Retry when the limit resets (HH:mm)` button, driven by the same
`resets_at` the backend stamps on the failed turn.

Clicking it arms a client-side timer for the reset moment and swaps the
button for a live countdown (`Retrying at HH:mm — in 12m 03s`) plus a
Cancel control. When it fires it calls `aui.message().reload()` — the exact
call behind the Retry button — exactly once. If that retry 429s again the
card (and the button) simply reappear; nothing repeats unattended.

Deliberately minimal (maintainer option B): no `retry in 1h/3h/6h` menu,
no custom time picker, no persisted scheduler, no backend auto-resume. The
timer lives in the mounted card only: cancel, unmount, session switch, a
manual Retry or any new message (thread running / message no longer the
tail) all clear it, and closing the app fires nothing. The button is shown
only while the reset is ahead and inside `setTimeout`'s 2^31-1 ms ceiling
(a larger delay would fire immediately in browsers).

- apps/desktop/.../assistant-message.tsx::ScheduledRetryAction
- lib/error-surface.ts: formatResetClock / scheduledRetryDelayMs /
  formatCountdown (formatLimitReset now reuses the clock helper)
- i18n keys errorRetryAtReset / errorRetryScheduled /
  errorRetryScheduledCancel in types + en/zh/zh-hant/ja/ar
- docs: website/docs/user-guide/desktop.md error-card section
- tests: two invariant vitest cases with fake timers (fires once at
  resets_at and not before; Cancel/unmount never fire; past reset hides
  the button) — red on the base component, green here.

Subject: [PATCH 104/240] catalog: rename jev-approval-provider ->
 jev-approvals, bump sha

The plugin was renamed and restructured since the original entry, so the old
filename, name, version, category and pin are all stale.

  name      jev-approval-provider -> jev-approvals
  sha       980b3d84 -> a19e332f (plugin-catalog/README rule 4: re-reviewed bump)
  version   0.1.0 -> 0.2.0
  category  tools -> models (matches the other model-provider entries)

Upstream changes adopted in this range:
- Approvals-only provider `typesafe-jev` (single alias `jev`); the plugin id and the
  provider name are deliberately different and both covered by tests.
- Second route: OpenRouter's decisions endpoint, selected by base_url alone, returning
  the identical typed answers. Model lists are fetched live from whichever upstream is
  configured instead of a hardcoded tuple.
- A `pre_tool_call` hook that existed briefly in the range was removed before this pin;
  capabilities below are empty because the plugin registers no tools, hooks or
  middleware at a19e332 (doctor: "0 tool(s), 0 hook(s)").
- Hardening: answer validation, egress redaction, bounded retries, a size-capped
  decision log.

Verified at the pinned SHA on a fresh clone:
  scripts/validate_plugin_catalog.py  -> OK: 1 file(s) valid
  hermes plugins validate plugin      -> Validation passed (security scan: caution)
  hermes plugins doctor plugin --ci   -> OK, jev-approvals 0.2.0 (model-provider)

The caution findings are the self-test's hostile fixtures (recursive root delete, raw
block-device write, credential paths) living under plugin/tests/, plus the policy
comments in __init__.py that quote the same shapes. They are what the suite asserts the
guardian DENIES.

Still labelled a proof of concept in the description, the README header and the manifest.

Subject: [PATCH 110/240] feat(tui_gateway): session.info reports the wire
 level the route sends for the effort

`ultra` is a Hermes-internal ladder step that every route clamps (to `max` on
OpenAI-compatible wires, per-model on Codex). The CLI already says so via
`agent/reasoning_effort.py::effort_display_label` ("ultra (sends max on this
route)"), but the renderers only ever received `reasoning_effort`, so the
Desktop and TUI had nothing to label a clamp with and showed Ultra as a level
of its own.

`_session_info` now also emits `reasoning_effort_wire`: the result of the same
`clamp_effort(route_supported_efforts(provider, model))` the request path uses
("" when unset/none, equal when verbatim). Clients label a clamp from this
value alone instead of duplicating the Codex per-model effort tables in TS.

Contract: `SessionLiveInfo.reasoning_effort_wire` + regenerated apps/shared
outputs. Part of #61634.

Subject: [PATCH 111/240] fix(desktop,tui): reasoning pill and effort rows say
 ultra sends max on this route
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Desktop pill, the catalog row meta and the effort radio row rendered a
clamped pick as a plain "Ultra", and the TUI status bar as "ultra" — presenting
a Hermes-internal step as a wire level the route does not have, while the CLI's
`/reasoning` shows "ultra (sends max on this route)" (#115876).

Both surfaces now read `session.info.reasoning_effort_wire`:
- Desktop pill / catalog row meta: compact "Ultra→Max", tooltip and aria-label
  "Effort: Ultra (sends Max on this route)" (new `modelOptions.sendsOnRoute`
  string in every locale, mirroring the CLI wording).
- Effort radio row for the selected clamped level: "Ultra (sends Max on this
  route)".
- TUI status bar: "ultra→max".
- Unknown wire ('' — not stamped yet, or an optimistic pick) or a verbatim
  level makes no claim, so nothing changes on routes that send the level as
  is. `setCurrentReasoningEffort` and the tile optimistic write clear the wire
  so a stale clamp never pairs with a new pick until the gateway re-stamps.

Docs: one sentence in the Desktop guide. Part of #61634.

Next to it, a **reasoning pill** shows the active model's effort level (`Med`, `High`, …) and opens the same options directly, so you can change effort without finding the model's row. The pill is hidden for models whose catalog reports no reasoning control. When the route clamps a Hermes-internal step (`ultra` is sent as the route's strongest level, e.g. `max`), the pill shows both ends (`Ultra→Max`) and its tooltip spells out the same wording as the CLI, `Ultra (sends Max on this route)`, so the level you see is the level that is sent. When the gateway flags a switch as risky (a large cached context, an expensive model, a data-training tier), the app asks first in a dialog: **Switch anyway** applies it, **Keep current model** (or Esc) leaves everything as it was.
 
 The **microphone** is dictation; hover it and the other voice toggles fan out above it — **Read replies aloud** and the **wake word** ear. A toggle that is on shows as a solid disc. Starting a full voice conversation stays on the primary button to the right. In the HUD and in narrow tiles the same controls fold into one menu behind the mic instead. When dictation talks to the speech-to-text provider directly (client-direct voice), the request honours the same `stt.openai.timeout` budget (default 60 s) as the gateway's own transcription client, so a slow endpoint fails with "Transcription timed out" instead of leaving the mic stuck on transcribing.

Subject: [PATCH 112/240] fix(doctor): name the processes holding a retired WAL
 generation instead of a green state.db
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After the deleted-WAL guard fires, every SessionDB open raises
DeletedWalGenerationError, yet `hermes doctor` printed "✓ state.db exists"
and "0 process(es) holding the DB open" with rc 0 (#110054). It only counted
holders of the CURRENT state.db inode; the processes wedging the store are
the ones holding the RETIRED -wal/-shm inodes, and nothing in-product named
them — while the chat explainer sends users to exactly this doctor.

Ask iter_deleted_sqlite_sidecar_holders (the helper the guard itself uses)
first. When it names holders: warn with their PIDs, record a stop-them issue
line pinned to the active profile, and return before the health/stats/WAL
probes — a read-only connect on the new generation is another opener, and
--fix must not checkpoint under them. No kill path, no new module.

Subject: [PATCH 113/240] refactor(doctor): share the holder pid renderer and
 mirror the guard's remedy

doctor_platform already rendered "PID N (cmd)" inline for the journal-mode holder report;
the retired-WAL warning needs the same text, so the loop moves to
hermes_state_holders.describe_holder_pid and both sites call it. The issue line now names
the same writers the DeletedWalGenerationError message names (gateway, dashboard, cron)
and repeats "do not delete the WAL yourself", so doctor and the guard tell one story.
The test also spies _state_db_stats, the probe that printed the literal
"0 process(es) holding the DB open" line the issue is about.

+### Cold-boot pending queue (Optional)
+
+By default the adapter drops server-side pending updates on a cold boot
+(`drop_pending_updates=True` on the first `start_polling`). That fits
+always-on servers: a restart means "clean up," and the queue is treated as
+stale. It does not fit hosts that turn off (a desktop shut down overnight):
+messages sent while the gateway is offline sit in Telegram's Bot API queue,
+and the next boot discards them before Hermes ever sees them — silently, no
+log, no retry.
+
+Set `drop_pending_on_cold_boot: false` to receive that backlog in order on
+startup instead:
+
+```yaml
+platforms:
+  telegram:
+    extra:
+      drop_pending_on_cold_boot: false
+```
+
+Notes:
+
+- Default is `true`: existing behavior is unchanged unless you opt in.
+- Watcher reconnects (brief network outages with the process still alive)
+  always preserve the queue regardless of this setting.
+- Conflict recovery still drops pending updates to terminate the competing
+  `getUpdates` session — that path is unrelated to this knob.
+- After a crash, a preserved queue can redeliver an update the crashed
+  instance partially processed. Telegram's offset usually prevents this,
+  but time-sensitive commands sent during a long outage will run on boot.
+
 ### Command menu priority and cap (Optional)
 
 Hermes registers its command menu automatically when the Telegram gateway starts. The menu is built from the central slash-command registry plus eligible plugin/skill commands, then capped so Telegram accepts the payload reliably. The default cap is 60 commands — enough to keep all built-in commands plus common skill commands visible.

Subject: [PATCH 115/240] refactor(telegram): share the cold-boot queue
 decision and log it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cold-boot queue policy was computed inline at both start paths, and the
default (drop) was silent — a command sent while the gateway was offline
vanished with no log line (the second half of #71811).

One helper now owns the decision and logs it on every cold boot, so an
operator can tell which policy applied. Behaviour is unchanged.

Subject: [PATCH 116/240] test(telegram): cover the webhook start path for the
 cold-boot queue knob

The knob's tests drove _start_polling_mode only, so a policy regression on
the webhook start path went undetected. The flag is not a no-op there: PTB
feeds it to delete_webhook/set_webhook, which drop Telegram's stored updates.

Asserts the cold-boot flag follows the knob, that the decision is logged, and
that a watcher reconnect still preserves the queue with the knob at its
default (the #46621 guarantee).

Subject: [PATCH 133/240] fix(plugin-catalog): re-pin
 hermes-project-stewardship after dependency fix

Re-pins to eb1ac9b, which declares fastapi and httpx2 in
[project].dependencies. pyproject previously had dependencies = [], and
Hermes' installer gives pyproject precedence over plugin.yaml's
python_dependencies, so a catalog install resolved no deps at all and the
dashboard half failed to import.

Verified with upstream hermes_cli.plugin_python_deps.read_declaration at
the new sha: specs=('fastapi>=0.104,<1', 'httpx2>=2.7,<3'), source='pyproject'
(it reported specs=() before). doctor_plugin against main: ok, no findings.
Upstream suite: 453 passed, 6 skipped; uv lock --check clean.

Subject: [PATCH 140/240] run: quiesce cron/deferred workers before DB close

This adds fail-closed logic: if cron or deferred writers outlive the quiesce timeout, we skip closing the SessionDB to avoid close-time data corruption.

Subject: [PATCH 141/240] refactor: gate the SessionDB close on live cron
 writers after the executor join
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cherry-picked fix waited on cron AND deferred workers in a blocking
time.sleep loop before the executor join, and returned early before
_shutdown_executor() ran. That left the executor unsealed (the #101118
regression), stalled the async stop phase, ignored the configured cron
drain budget, and double-covered deferred workers, which are executor
futures already joined by _shutdown_executor().

Keep only the verified gap: cron jobs run on the scheduler's own pool, so
the executor join never sees them. Check _active_cron_job_count() AFTER
the executor is sealed and fail closed the same way the executor-busy
branch does — no second wait, the cron drain already spent its budget.
Restores the #82161 comment terminator the cherry-pick spliced over.

Subject: [PATCH 142/240] test: cover the live-cron-writer path in the existing
 shutdown quiesce test

Replace the PR's standalone 154-line test module with one invariant test in
the file that already exercises _stop_quiesce_and_close_session_dbs, reusing
its fake gateway: a non-zero cron count after the drain must leave the
SessionDB and the shared registry unclosed while the executor is still
sealed. The quiet path is already covered by the neighbouring tests.

Red on origin/main: "SessionDB closed despite a live cron writer:
['close:session_db', 'close_all']".

Subject: [PATCH 143/240] fix(gateway): the shutdown close gate also counts
 API-server runs

API-server runs execute on the loop's default executor (platforms/api_server.py), so like cron
jobs they are invisible to the self._executor join and would have state.db closed under them.
One predicate covers both outside-the-executor writers. The "executor quiesced" marker is
logged before the gate because on this path the executor genuinely was sealed and joined.
The test is parametrized over the two counters.

Subject: [PATCH 144/240] fix(gateway): count API-server runs before the
 adapters are released; include deferred workers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_stop_release_runtime_state clears self.adapters one phase before the SessionDB close gate,
so a live lookup through _api_server_hook always read 0 there — the API term was dead and the
parametrized test could not see it because it replaced the method. The count is now taken
onto the stop context before adapters.clear(). Deferred hygiene workers also run on the
loop's default executor (run_turn.py), so their counter joins the gate; the earlier claim
that they were self._executor futures was wrong. The warning names each source separately.
The API test case goes through the real hook with a fake adapter in gw.adapters, so moving
the snapshot after the clear fails it.

Subject: [PATCH 149/240] feat(evals): fast-jev-compaction arm + compaction
 cost metering in the compaction eval
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a Python port of tamaratran/fast-jev-compaction as an eval policy
(`engine: jev`): TypeSafe's Jev decision model scores every tool call and
result over the whole history and stale ones are dropped or truncated, with
no summary and no rewriting of user/assistant text. Transport is OpenRouter's
Decisions API (~typesafe/jev-latest). A state that cannot fit the plugin's
25K-token ceiling is recorded as a fallback (the plugin's own behaviour)
rather than scored.

Every arm now reports what its compaction step cost (calls, tokens, USD —
Jev reports cost directly; summary calls are metered through the
compressor's call_llm binding and priced at OpenRouter list), and the run
writes the harness's own answer/judge token bill so the eval's spend is
visible. The question cache key includes --cap-tokens so different caps on
one transcript no longer share a bank.

Why: measure remaining tokens, compaction cost and recall accuracy of the
"decide, don't summarize" approach against current/lean on real Hermes
lineages before deciding whether any of it belongs in the compressor.

+A policy with `"engine": "jev"` bypasses `ContextCompressor` and runs

+OpenRouter's Decisions API (`~typesafe/jev-latest`, needs
+`OPENROUTER_API_KEY`); `"jev": {...}` overrides `JevOptions` (threshold,
+pinned tail, state/request ceilings). When the fitted state cannot get under
+the 25K-token ceiling the arm records `jev_fallback` (the plugin throws and
+Claude Code falls back to its built-in summary) instead of scoring.
+
+Every arm's result carries its compaction spend: `compaction_calls`,
+`compaction_input_tokens` / `compaction_output_tokens`, `compaction_model`
+and `compaction_cost_usd` (Jev reports cost directly; summary calls are
+priced at the OpenRouter list price of the model that answered). The run
+also writes `eval_usage.json` — the harness's own question/answer/judge
+token bill.

+"""fast-jev-compaction as a compaction eval arm.
+
+Python port of https://github.com/tamaratran/fast-jev-compaction (MIT), which
+replaces the compaction summary with per-tool-call keep/drop decisions from
+TypeSafe's Jev "System One" model: the whole history (tool results replaced by
+a size note) is sent as `state`, two `noul` questions per candidate call ask
+whether the call and whether its verbatim result must stay, and the transcript
+is rebuilt with nothing rewritten. Text messages are never touched.
+
+Differences from the TypeScript original are format-only: Hermes transcripts
+carry `tool_calls` on assistant rows and one `role: tool` row per result, so a
+"message" here is one chat row and `preserve_recent_messages` counts rows.
+
+Transport is OpenRouter's Decisions API (`POST /api/alpha/decisions`, model
+`~typesafe/jev-latest`), so the eval needs only OPENROUTER_API_KEY.

Subject: [PATCH 150/240] evals(compaction): matched-budget Jev/recency arms +
 2026-09-19 fast-jev scorecard

Adds an eval-only budget selector to the Jev arm (rank tool pairs by Jev
keep_result or by recency, keep until a token budget) so Jev's judgment can
be separated from the effect of keeping text verbatim, and records the
3-transcript scorecard: default Jev +32 pts recall at 2.1x retained tokens,
1/9 the compaction cost; at matched budget Jev ranking ties recency.

+# fast-jev-compaction vs Hermes compaction — 3-transcript scorecard (2026-09-19)
+
+Question asked: does https://github.com/tamaratran/fast-jev-compaction ("replace the
+compaction summary with Jev decisions: score every tool call/result, drop or truncate
+stale ones, keep everything else verbatim") beat our compressor on remaining tokens,
+compaction cost and recall accuracy?
+
+Harness: `evals/compaction/runner.py` with the new `engine: jev` arm
+(`evals/compaction/jev_arm.py`, a Python port of the plugin over OpenRouter's Decisions
+API, `~typesafe/jev-latest` → served as `typesafe/jev-1.13-20260917`). Three real 500K-token
+lineage prefixes from state.db (PR review campaign, system-prompt token analysis, SIGSEGV
+fix), 15-question recall exam each, same bank for every arm, answered and judged by the
+configured `auxiliary.compression` route (gemini-3.8-flash via Nous). A fourth transcript
+(541 tool calls in 500K) could not be fitted into Jev's 25K-token state ceiling even at the
+last fitting stage — the plugin throws there and Claude Code falls back to its built-in
+summary; recorded as `jev_fallback`, not scored.
+
+## Results (recall % @ retained tokens; compaction cost and wall time per event)
+
+| policy | prreview | sysprompt | sigsegv | AVG | compaction $ | compaction s |
+|---|---|---|---|---|---|---|
+| current (main) | 36.7 @ 40K | 50.0 @ 64K | 43.3 @ 61K | **43.3 @ 55K** | $0.061 | 36.9 |
+| lean | 33.3 @ 40K | 53.3 @ 65K | 36.7 @ 61K | 41.1 @ 55K | $0.062 | 33.4 |
+| jev (plugin defaults) | 70.0 @ 50K | 63.3 @ 112K | 93.3 @ 181K | **75.5 @ 115K** | $0.007 | 1.4 |
+| jev_tail40 (40 pinned rows) | 73.3 @ 71K | 63.3 @ 179K | 93.3 @ 213K | 76.6 @ 154K | $0.006 | 1.4 |
+| jev_t15 (threshold 0.15) | 93.3 @ 372K | 76.7 @ 332K | 100.0 @ 484K | 90.0 @ 396K | $0.007 | 1.4 |
+| jev_top60k (Jev-ranked, 60K tool budget) | 70.0 @ 113K | 70.0 @ 173K | 93.3 @ 243K | 77.8 @ 176K | $0.007 | 1.5 |
+| recent_top60k (recency-ranked, same budget) | 76.7 @ 114K | 63.3 @ 174K | 93.3 @ 245K | 77.8 @ 177K | $0 | 0.0 |
+
+`current` and `lean` are the same code path on today's main (lean tail is the default), so
+their 2–7 pt spread on identical context is the exam noise floor (15 questions ≈ ±3.3 pts).
+Per-question paired comparison, jev vs current across 45 questions: 17 wins, 1 loss, 27 ties.
+
+## Findings
+
+1. **Jev's default arm is +32 pts recall (75.5 vs 43.3) at 2.1× the retained tokens
+   (115K vs 55K), for 1/9 the compaction cost ($0.007 vs $0.061) in 1/25 the time
+   (1.4 s vs 37 s).** On the one transcript where the sizes are comparable (prreview,
+   50K vs 40K) it still wins 70.0 vs 36.7.
+
+2. **The recall gain is verbatim text, not Jev's judgment.** At the plugin's 0.5 threshold
+   Jev's `keep_result` never exceeded 0.20 (median 0.15) and `keep_call` topped out at 0.50,
+   so it dropped 100% of the 851 unpinned candidates across all three transcripts
+   (kept=0, result-truncated=0). The default `jev` arm is therefore behaviourally identical
+   to "delete every old tool call + result, keep every user/assistant row verbatim". The
+   facts the summary loses (delegation ids, root causes, config keys, exact error strings)
+   sat in assistant text the whole time.
+
+3. **At a matched budget Jev's ranking ties plain recency: 77.8 vs 77.8.** Keeping 60K
+   tokens of tool pairs ranked by `keep_result` (jev_top60k) vs ranked by position
+   (recent_top60k) gives the same average; per transcript it is +6.7 / −6.7 / 0, inside the
+   noise floor. Lowering the threshold to 0.15 (jev_t15) reaches 90% but retains 396K of
+   500K — that is not compaction.
+
+4. **The state ceiling does not fit Hermes scale.** Jev's 32K window forces the whole
+   history into 25K tokens; at 500K every transcript needed the harshest fitting stages
+   ("old calls compacted/merged", "old messages collapsed") and one of four could not fit at
+   all. The plugin is designed for Claude Code's ~200K compaction point; a 1M-window Hermes
+   session compacting at 500K+ will fall back to the summary regularly, and once the tool
+   results are gone a second compaction has nothing left to remove.
+
+5. **Cost shape.** Jev: 5–7 requests per compaction, ~125–200K input tokens total at
+   $0.042/M ≈ $0.005–0.008, ~1.5 s wall. Our summary: one gemini-3.8-flash call over
+   52–60K input tokens ≈ $0.06, 25–49 s. Both are noise against the per-turn cost of the
+   retained context that follows (115K vs 55K tokens on every subsequent turn).
+
+## What this suggests for the compressor
+
+The cheap win is not a new decision model but a retention rule the data supports: **keep
+user/assistant text verbatim and drop/truncate old tool results before anything is
+summarised.** We already have that layer (`_prune_old_tool_results`, phase 1); today it is
+followed by a summary that also rewrites assistant text, and that rewrite is where the
+recall goes. A "prune-only until the tail budget is reached, summarise only the remainder"
+posture would capture most of Jev's gain at zero extra cost. If a scoring model is wanted
+for the prune ranking, Jev is fast and cheap enough (1.5 s, < 1¢) but this data shows no
+signal over recency at equal budget; re-test before wiring it in.
+
+## Method notes
+
+- Transcripts reconstructed with `scripts/reconstruct_lineage.py` from a state.db copy;
+  not committed. Question banks generated from the region current compaction summarises
+  (the most conservative boundary) and cached per transcript+cap so every arm answers the
+  identical exam.
+- The `jev` arm counts rows (Hermes has one `role: tool` row per result), so
+  `preserve_recent_messages: 6` pins fewer turns than in Claude Code; `jev_tail40` widens
+  it to roughly lean's 25K tail and changes nothing (+1 pt).
+- Eval spend for the whole run (question generation, 634 answer/judge calls): 43.5M input
+  tokens ≈ $33.6 at gemini-3.8-flash list, through Nous inference. Jev spend across all
+  arms: $0.08 via OpenRouter.

Subject: [PATCH 151/240] evals(compaction): Jev repeated-compaction simulator,
 cycle data and verdict

jev_cycles.py compacts a lineage with Jev every time the estimate crosses a
threshold and records freed tokens, text floor and fitting stage per cycle.
Six runs show the floor (never-removed user/assistant text) is the binding
limit: freed-per-cycle decays to 0-8% and a 200K-window host is stuck after
0.42M tokens; >~500 tool calls between compactions cannot fit the 32K state.
Scorecard gains a decisive verdict section.

 # fast-jev-compaction vs Hermes compaction — 3-transcript scorecard (2026-09-19)
 
+## Verdict
+
+**Do not adopt Jev as Hermes' compaction. Do adopt the retention rule it demonstrates.**
+
+- The +32 pt recall win is entirely "keep user/assistant text verbatim, delete old tool
+  output". Jev itself dropped 100% of 851 candidates at its default threshold and, at a
+  matched token budget, ranked no better than plain recency (77.8 vs 77.8).
+- Jev-only compaction is a one-way ratchet: the text floor grows every cycle and is never
+  reduced, so freed-per-compaction decays (89% → 55%, 76% → 20%, 63% → 8% over 32–40
+  cycles) and a text-heavy session on a 200K-window host hit a hard stop after 0.4M tokens
+  of work (floor ≥ threshold, 0% freed). A summary path is still required; Jev could only be
+  a pre-pass.
+- The 32K request window forces the whole history into 25K tokens: in every measured cycle

 Question asked: does https://github.com/tamaratran/fast-jev-compaction ("replace the
 compaction summary with Jev decisions: score every tool call/result, drop or truncate
 stale ones, keep everything else verbatim") beat our compressor on remaining tokens,
@@ -75,6 +98,45 @@ posture would capture most of Jev's gain at zero extra cost. If a scoring model
 for the prune ranking, Jev is fast and cheap enough (1.5 s, < 1¢) but this data shows no
 signal over recency at equal budget; re-test before wiring it in.
 
+## Repeated compaction: how many cycles does Jev-only compaction survive?
+
+`scripts/jev_cycles.py` feeds a lineage chronologically and compacts with Jev (plugin
+defaults) every time the estimate crosses the threshold; 500K ≈ our 1M-window posture, 160K
+≈ a 200K-window host. Raw JSON per run in `results/jev-cycles-2026-09-19/`. Jev spend for all
+six runs: $0.60.
+
+| run | cycles | raw session consumed | freed per cycle | text floor | end state |
+|---|---|---|---|---|---|
+| prreview @500K | 32 | 11.4M (whole lineage) | 89% → 55% | 43K → 139K | still working |
+| sysprompt @500K | 40 | 8.6M of 23.3M | 76% → 20% | 91K → 240K | degrading |
+| sigsegv @500K | 40 | 5.2M of 8.6M | 63% → 8% | 175K → 359K | 40K freed/cycle; wall ≈ 8M |
+| prreview @160K | 60 | 3.9M of 11.4M | 87% → 22% | 12K → 87K | compacting every ~14 rows |
+| sigsegv @160K | 11 | 0.42M of 8.6M | 52% → 0% | 85K → 151K | **STUCK** (floor ≥ threshold) |
+| afff57 @500K | 0 | — | — | — | fallback on cycle 1 (541 calls) |
+
+Reading: every cycle has candidates (new tool calls arrive between compactions and Jev
+drops ~all of them; 200+ cycles, zero orphaned call/result pairs), so "nothing left to
+remove" never happens. What runs out is headroom: each cycle frees at most
+`threshold − floor`, and the floor (all user/assistant rows) only grows. Well before the
+hard stop the session runs permanently near the window: sigsegv @500K at cycle 40 compacts
+every ~40K tokens of new work with every turn billed at ~460K input.
+
+## The 32K window in practice
+
+- `state_tok` was 24,8xx–25,000 in every one of ~180 measured cycles: the ceiling always
+  binds. Fitting stages reached at 500K: "old messages collapsed" (texts → `[… N chars
+  omitted …]`), "old calls compacted" (one line per call, input cut to 60 chars), "old
+  messages left out" (text-only old rows removed from the state), "old calls merged". Jev
+  never sees tool result contents (by design) and, at these stages, barely sees message
+  text either — it decides on tool name, input stub, result size and the last 3 user prompts.
+- Hard limit: ~500+ unpinned tool calls between compactions cannot fit (afff57, 541 calls);
+  the plugin throws and the host falls back to its summary. The text floor does not affect
+  fit (old text rows are left out of the state); the call count does.
+- Requests: full state resent per batch of ~40–80 calls → 5–8 concurrent requests per
+  cycle at 500K, 1–2 s, $0.005–0.008.
+- Untouchable content: anything in assistant text (pasted logs, long analyses) is never
+  compacted, which is exactly what makes the floor grow.

Programmatic tool-result removal as the primary compaction leaves ~2x the
context billed every turn and tightens compaction cadence every cycle (each
one a prompt-cache break); the summary's one-time ~90% reduction keeps a
long conversation cache-warm. The recall gap points at summariser retention
of identifiers in assistant text, not at a cadence change.

 ## What this suggests for the compressor
 
-The cheap win is not a new decision model but a retention rule the data supports: **keep
-user/assistant text verbatim and drop/truncate old tool results before anything is
-summarised.** We already have that layer (`_prune_old_tool_results`, phase 1); today it is
-followed by a summary that also rewrites assistant text, and that rewrite is where the
-recall goes. A "prune-only until the tail budget is reached, summarise only the remainder"
-posture would capture most of Jev's gain at zero extra cost. If a scoring model is wanted
-for the prune ranking, Jev is fast and cheap enough (1.5 s, < 1¢) but this data shows no
-signal over recency at equal budget; re-test before wiring it in.
+Nothing structural. Keeping text verbatim wins the closed-book exam but at 2.1× retained
+tokens per turn and a compaction cadence that tightens every cycle (prompt cache broken far
+more often); the summary's one-time 90% reduction is the better trade for a long-lived
+cached conversation. The actionable residue is summariser quality: the misses were exact
+identifiers in assistant text, which the anchor index is meant to capture — check its
+coverage on these three banks before touching anything else.
 
 ## Repeated compaction: how many cycles does Jev-only compaction survive?

Subject: [PATCH 155/240] evals(compaction): document the Jev
 repeated-compaction recipe and add the table renderer

jev_cycles_report.py renders the cycles/freed/floor/end-state table from
jev_cycles.py outputs; README carries the exact commands, thresholds and
cost so the diminishing-returns and stuck/fallback findings can be
reproduced. Fallback records now count the real tool calls.

+## Repeated-compaction simulation (`scripts/jev_cycles.py`)
+
+A one-shot recall score misses the failure mode of "decide, don't summarise"
+compaction: it never removes user/assistant text, so each cycle frees only
+`threshold − text_floor` and the floor grows monotonically. `jev_cycles.py`
+feeds a lineage chronologically and compacts with the Jev arm every time the
+estimate crosses the threshold, recording per cycle: tokens before/after,
+percent freed, text floor, candidate/dropped calls, fitting stage, state
+tokens, requests and Jev cost. It stops at end of transcript, when a cycle
+frees nothing (`stuck`), or when the state cannot fit Jev's 25K ceiling
+(`fallback` — the plugin throws there).
+
+```bash
+# lineage from a state.db COPY (see above), then, with OPENROUTER_API_KEY set:
+python evals/compaction/scripts/jev_cycles.py /path/lineage.json 500000 40 > cycles-500k.json
+python evals/compaction/scripts/jev_cycles.py /path/lineage.json 160000 60 > cycles-160k.json
+python evals/compaction/scripts/jev_cycles_report.py cycles-*.json      # markdown table
+```
+
+Threshold 500000 ≈ Hermes' 1M-window posture; 160000 ≈ a 200K-window host.
+Each cycle costs 1–8 Jev requests (< 1¢); a 40-cycle run is ~$0.20. The
+2026-09-19 runs are committed under `results/jev-cycles-2026-09-19/` (counts
+only, no transcript content) and summarised in `SCORECARD-2026-09-19-jev.md`:
+freed-per-cycle decayed 63% → 8% / 76% → 20% / 89% → 55% over 32–40 cycles,
+one 200K run was stuck after 0.42M tokens of work, one transcript never fit.

Subject: [PATCH 158/240] catalog: add typesafe-skill-router (community)

TypeSafe (Jev) skill routing as a pre_llm_call hook: the request is routed
before the model call and the one skill from the live roster that fits it is
named in a single <skill_relevance> line on the user message. Nothing is
injected when nothing fits, and the system prompt is never touched (it is the
prompt-cache prefix).

Opt-in (enabled: false), stdlib only, no self-updating code. Pinned to
DECRUX9812/typesafe-skill-router@82cfa51, where `hermes plugins validate`
passes including the isolated capability probe. Owner submission.

Subject: [PATCH 164/240] plugin-catalog: add lancedb-suite
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Local-first LanceDB vector memory provider. Registers the memory provider
`lancedb-suite` (the catalog key `lancedb` belongs to the upstream project
lancedb/hermes-agent-memory, which registers the same provider name — the
mnemosyne precedent), pinned at v1.5.0.

The plugin lives in the repository's `plugin/` subdirectory; the pin is a
40-character commit that is also the v1.5.0 tag.

Checks, run at the pinned sha:

- `hermes plugins validate`: all checks green, `security scan — safe`
  (the scanner runs on the `plugin/` subdir the CI clones, not the whole repo)
- declared capabilities match reality: the 8 declared tools are exactly the 8
  the provider registers
- no self-updating code under the scanned sources
- `hermes plugins install 3L0935/hermes-lancedb-memory-suite/plugin` verified
  end to end into a clean HERMES_HOME

Notable behaviour: automatic memory injection is off by default
(`memory.lancedb-suite.auto_prefetch: true` restores it). The core splices
prefetch output onto the user message as relevant context, and a measured
ambiguous query pulled an unrelated memory through the vector path, so recall
is a tool call rather than a push.

Subject: [PATCH 165/240] plugin-catalog: pin lancedb-suite to v1.5.2

The entry pinned 1.5.0/3bb0a64. v1.5.2 fixes the visualizer layout on
phone, tablet and foldable (navigation was removed below 640px, the
topbar and filter bar overflowed their frame, touch targets were 25px).
The pin is what the installer resolves, so a stale one ships the old UI.

Subject: [PATCH 183/240] fix(api-server): anchor the Responses current turn on
 this turn's user row, not a history prefix match

`_response_messages_turn_start_index` located the current turn by matching
`result["messages"]` against `conversation_history + [user]` row by row. The
loop repairs host-fed history before its first call (consecutive assistant or
user rows merge, orphan tool results drop) and compaction rewrites it, so the
transcript legitimately stops sharing a prefix with the client history; the
match then returned 0 and the WHOLE transcript was treated as the current
turn: earlier turns' function_call / function_call_output items were replayed
as this turn's `output` / `run.completed` turn_messages, and the stored
`previous_response_id` chain grew by another copy of the history every turn.

Anchor on the loop's canonical current-turn user index instead
(`agent.turn_context.reanchor_current_turn_user_idx`: last user row that
says this turn's text, else the last user-originated row), and keep the
semantic prefix match only for suffix-only results without a user row
(mocked/legacy paths). The boundary logic moves to the topical sibling
`api_server_turn_boundary.py`; the routes mixin delegates.

The dedupe test that asserted "divergent transcript => append history +
transcript" encoded the duplication itself; it now asserts the fallback for
the case it actually exists for (a suffix-only result).

Fixes #89891

 The server reconstructs the full conversation from the stored response chain — all previous tool calls and results are preserved. Chained requests also share the same session, so multi-turn conversations appear as a single entry in the dashboard and session history.
 
+Each response's `output` lists only that turn's items (its `function_call` / `function_call_output` entries and final `message`), never earlier turns' tool calls — including when Hermes repaired the supplied history before the call (merged consecutive `assistant` or `user` items, dropped orphan tool results) or compacted it mid-chain. The stored chain is that repaired transcript, so the history does not grow by a second copy on every turn.

Subject: [PATCH 184/240] feat(auth): opt-in browser authorization-code + PKCE
 login for openai-codex
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`hermes auth add openai-codex --browser` (or `auth.codex_login_flow: browser`)
signs in through OpenAI's authorize endpoint with PKCE and receives the code on
the loopback listener `http://localhost:1455/auth/callback` — the redirect URI
fixed by the public Codex client registration. Organizations that disable the
device-code grant could not log in at all before (#95743).

Device code stays the default and is never auto-replaced: the browser flow runs
only when the user asks for it, and when :1455 is already taken (a Codex CLI
sign-in in progress) Hermes prints why and falls back to device code instead of
failing. State is a 32-byte nonce compared in constant time; the code, verifier
and tokens are never logged or printed. Credentials land in the existing pool
add path with source `manual:loopback_pkce`, so refresh/rotation treat them like
any other independently added Codex account.

Derived from #97058 by @astraltrekkin (re-homed after the auth_codex.py split;
the fixed registered port replaces the free-port scan, and the flow is opt-in
instead of auto-selected per the maintainer's ruling).

Fixes #95743

Subject: [PATCH 185/240] test(auth): invariants for the opt-in Codex browser
 PKCE login

Two invariants, both red on origin/main: --browser drives a real loopback
listener + PKCE-verified token exchange and stores source manual:loopback_pkce;
the default stays device code without ever binding the listener, and a busy
callback port falls back to device code with a clear notice.

Providers page (Codex note), CLI reference, credential-pools command table and
the OAuth-over-SSH port table, so the fixed :1455 listener and its device-code
fallback are discoverable where users look for Codex login help.

-The OpenAI Codex provider authenticates via device code (open a URL, enter a code).

+The OpenAI Codex provider authenticates via device code by default (open a URL, enter a code). Organizations that disable the device-code grant can opt in to the browser authorization-code + PKCE flow instead: `hermes auth add openai-codex --browser` (one login) or `auth.codex_login_flow: browser` in `config.yaml` (every Codex login, including `hermes model`). That flow listens on `http://localhost:1455/auth/callback` — the redirect URI registered for the Codex client, so the port is fixed; if it is already taken (a Codex CLI sign-in in progress) Hermes says so and falls back to device code. Over SSH the listener needs a tunnel (`ssh -N -L 1455:127.0.0.1:1455 user@host`, see [OAuth over SSH](../guides/oauth-over-ssh.md)). Hermes stores the resulting credentials in its own auth store under `~/.hermes/auth.json` and can import existing Codex CLI credentials from `~/.codex/auth.json` when present. No Codex CLI installation is required. Automatic adoption of the Codex CLI login (when Hermes' own refresh fails) is controlled by `auth.adopt_external_logins` — see [Borrowed CLI logins](../user-guide/security.md#borrowed-cli-logins).
 
-If a token refresh fails with a terminal error (HTTP 4xx, `invalid_grant`, revoked grant, etc.), Hermes marks the refresh token as dead and stops replaying it so you don't see a flood of identical auth failures. The next request surfaces a typed re-auth message instead. Run `hermes auth add openai-codex` (or `hermes model` → **ChatGPT or Codex Subscription**) to start a fresh device-code login; the quarantine clears on the next successful exchange.

 Device login can fail with `[SSL: UNEXPECTED_EOF_WHILE_READING]` or a TLS handshake timeout on Python/OpenSSL 3.5+ when a middlebox rejects post-quantum groups such as X25519MLKEM768 (curl may still work). A one-off dropped connection is not fatal: while waiting for your browser approval Hermes keeps polling through up to six consecutive transport errors (and retries the device-code request and token exchange twice) before giving up, so only a persistently broken network surfaces this error. Hermes does not change default TLS policy. Point `OPENSSL_CONF` at a config that restricts `Groups` to classic curves before running `hermes model`, or diagnose with TLS 1.2:

Subject: [PATCH 187/240] fix: session.create refuses a model its provider
 cannot serve

A composer, script or older client can pin a model override the selected
provider does not serve (gpt-5.5 on anthropic; the incident pair
deepseek/deepseek-v4-flash-0731 on openai-codex). The gateway minted the
session anyway and the FIRST turn died with the provider's 404, leaving a
dead chat the user had to diagnose and recreate.

session.create now checks the pair before any session state exists and
answers JSON-RPC -32602 naming the model, the provider and up to five
closest models from that provider's curated catalog (error.data carries
them structured). The check is offline and refuses only what Hermes knows
belongs elsewhere: a foreign-family name another native vendor's catalog
lists, or any foreign-family name on the strict OAuth catalogs
(openai-codex / xai-oauth). Custom endpoints, aggregators, same-family
names the curated list lacks and names no catalog lists stay permissive.
Without an explicit provider the pair is judged against the provider the
session would build with (profile config, then env) under the profile's
scope.

Direction and reject-before-side-effects shape from #96845 by
@victorftrdba, trimmed to the offline catalog rule.

Fixes #96817

 Within one authenticated gateway, resuming or activating a live session attaches another event subscriber rather than replacing the previous connection. Streaming and terminal events go to all attached clients; disconnecting one client does not end a session another client is viewing. Existing submit exclusivity and configured busy-input policy remain in force. Attached clients can steer the session's subagents; browser-controller results still require the connection that registered that controller. This does not enable independent gateway processes to write the same session, nor does it imply durable prompt admission across an owner restart.
 
+### Model overrides on `session.create`
+
+`session.create` accepts per-session `model` / `provider` overrides. A pair the provider cannot serve (`model: gpt-5.5` with `provider: anthropic`, or with no `provider` when the profile's configured provider is Anthropic) is refused up front with JSON-RPC code `-32602` instead of minting a session whose first turn fails at the provider; `error.data` carries `model`, `provider` and up to five `suggestions` from that provider's catalog, and `error.message` repeats them. The check is offline and only refuses names Hermes knows belong elsewhere: custom endpoints (`custom`, `custom:<name>`), aggregators (OpenRouter, Nous, …), models in the provider's own family that the curated list has not caught up with, and names no catalog lists are all accepted as before.
+
 ### Rewinding history on `prompt.submit`
 
 A rewind / edit / regenerate is a `prompt.submit` that drops part of the stored transcript before running the new turn. Because that write is a destructive rewrite of the session's durable rows, the gateway honors it only when the client states its intent:

Subject: [PATCH 189/240] fix(cron): a missing-credential preflight verdict
 names the profile and HERMES_HOME it read
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The blocked_config reason for a missing provider credential now carries
"[profile '<name>', HERMES_HOME <path>]" — the home the scheduler actually
read auth.json/.env from — under the ticker's profile scope, so a
multiplexed satellite profile reports its own home, not the gateway's
launch home.

Why: #116213 reports an openai-codex cron job blocked with "No Codex
credentials stored" while an interactive session under "the same"
HERMES_HOME resolves the credential. A 5-shape x 5-scope live matrix
(singleton, expired+refreshable, pool-only, ~/.codex only, none; root,
named profile, root-only auth, multiplex default/named) on origin/main
and on the reporter's build 345cd2b0 shows interactive and cron
preflight agree in every cell — both call the same
resolve_runtime_provider ladder and read the same store. The remaining
explanation is a scheduler process reading a different home than the
shell (Docker HOME vs HERMES_HOME, a service unit without the shell's
env, a satellite profile), which the bare verdict could not reveal.
Naming the store the verdict judged makes that mismatch visible in the
one alert the user receives.

Subject: [PATCH 190/240] feat(config): expose a custom route's canonical
 api_mode for metadata lookups

Custom providers already declare their wire protocol (api_mode / legacy
transport) on the entry, but nothing outside routing could read it: context
length resolution keyed Codex detection on the hostname, which a proxy on
127.0.0.1 never matches. get_custom_provider_api_mode() returns the canonical
transport of the first entry serving a base_url (None custom_providers loads
config, like the sibling context_length helper) so metadata decisions can
follow the route instead of the host.

Slim port of the helper from #116262 by @JoaoMarcos44.

Subject: [PATCH 191/240] fix(context): proxied Codex routes resolve the Codex
 OAuth window, not the direct-API catalog
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A Codex OAuth model (gpt-6-astra, gpt-5.6-sol/terra/luna, gpt-5.5, ...) served
through a proxy — a custom provider with api_mode: codex_responses at
http://127.0.0.1:8317/v1, or the openai-codex provider behind
HERMES_CODEX_BASE_URL / model.base_url — resolved 1,050,000 from
DEFAULT_CONTEXT_LENGTHS instead of the 272,000 Codex enforces. The compressor
then set its trigger at 525,000 tokens, ~2x past the Codex limit and its 272K
billing tier, and a day of Astra sessions burned two Pro weekly windows.

Root cause: step 2 of get_model_context_length treated any non-known hostname
as a generic custom endpoint and never looked at the route's transport, so the
Codex table two steps away was skipped. The decision key is now the route:
_is_codex_route() is true for provider openai-codex on any URL and for a custom
entry whose canonical api_mode is codex_responses. A custom Codex route answers
from the Codex OAuth table first (with the opted-in -900k bump; unknown slugs
still take the endpoint probes), the native provider skips the custom-endpoint
step and keeps its live catalog probe in step 5, and both bypass the persistent
cache so a stale 1.05M entry cannot outlive the fix. Explicit
providers.<name>.models[].context_length / context_length / model.context_length
overrides still win (step 0 runs first); chat_completions proxies are unchanged.

Reported with the exact resolver path by @0xble (#116199); route-keyed lookup
per @JoaoMarcos44 (#116262).

Fixes #116191

 Older configs used a top-level `custom_providers:` list instead. It still works — Hermes reads both — and `hermes update` auto-migrates it to the `providers:` dict (config v12). Field names differ slightly in the dict format: legacy `model` is `default_model`, and legacy `api_mode` is `transport`.
 :::
 
+**Context window on `codex_responses` proxies.** A custom entry with `transport: codex_responses` (a local Codex proxy, for example) resolves the context window of Codex OAuth models (`gpt-6-astra`, `gpt-5.6-sol`/`-terra`/`-luna`, `gpt-5.5`, …) from the Codex OAuth table — 272K for most slugs — not from the 1.05M direct-API catalog, so compression fires before the Codex backend's limit and its 272K billing tier. The decision follows the transport, not the hostname; the same holds for `openai-codex` behind `HERMES_CODEX_BASE_URL` or `model.base_url`. A per-model `models.<id>.context_length`, an entry-level `context_length`, or `model.context_length` still wins; the opt-in `-900k` picker variants keep their verified 900K.
+
 **Reasoning effort on custom endpoints.** The configured `reasoning_effort` (`/reasoning max`, `agent.reasoning_effort`) reaches a custom endpoint unchanged on both the `chat_completions` and the `codex_responses` transport — up to `max`; only the Hermes-internal `ultra` is clamped to `max`. Two exceptions follow the host rather than the entry: a custom entry pointed at `api.openai.com` keeps OpenAI's per-model ladder (`max` is a gpt-5.6-only level there), and an entry pointed at a provider whose profile publishes a per-model vocabulary (Ramp Router) is clamped to that catalog. An endpoint that rejects the level answers with an HTTP 400 instead of Hermes silently downgrading it.
 
 Some OpenAI-compatible endpoints need provider-specific request body fields. Add an `extra_body` map to the matching custom provider and Hermes will merge it into each chat-completions request for that endpoint:

Subject: [PATCH 192/240] fix: name host, attempts and request size when
 connect retries are exhausted

When every pre-stream connect attempt to an endpoint fails, the user only saw
"Connection error." repeated per outer retry; the host, the attempt count and
the serialized request size lived in agent.log alone. #97548's reporter had an
~829 KB Codex Responses request fail twice before the stream opened while short
chats went through, which is the request-size-limit signature, and nothing on
screen said so.

One buffered diagnostic line now flows through the existing retry-status path
(flushed on terminal failure, dropped on recovery) on both the Codex Responses
runtime and the Chat Completions stream worker: "Could not open a stream to
<host> after N attempts (request X KB); ...". The host comes from the failed
request's URL (the endpoint actually contacted, proxies included) and the size
from the buffered httpx request body. Re-entering the stream call from the
outer retry/fallback loop does not add another copy.

Part of #97548

+#### "Could not open a stream to `<host>` after N attempts (request X KB)"
+
+**Meaning:** every connect attempt to that endpoint failed before a single stream event arrived, so nothing was billed; the normal retry/fallback chain still runs afterwards. The line names the host actually contacted, how many attempts were made, and the serialized request size — the three things that separate an outage from a request-size limit.
+
+**Solution:** if the request is large (hundreds of KB — long coding sessions reach this once the context grows) and short new chats work, the endpoint or a proxy in front of it is likely rejecting bodies that size: raise its body limit, or run `/compress` to shrink the context. If the request is small, the endpoint is unreachable — check the `base_url`, then retry with `/retry`. `logs/agent.log` records the exception chain for each attempt.
+
 #### `/model` only shows one provider / can't switch providers
 
 **Cause:** `/model` (inside a chat session) can only switch between providers you've **already configured**. If you've only set up OpenRouter, that's all `/model` will show.

Subject: [PATCH 193/240] fix: video generation tools no longer let the agent
 pick the model
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

video_generate advertised an optional `model` argument (and the xAI edit/extend
tools a model override) so the LLM could route a single call to a different
model family — a different endpoint and billing tier — than the one the user
selected in `hermes tools`. image_generate never exposed this, and #83080 asked
to extend it there; the ruling is the opposite: models do not choose models.

The `model` property is gone from the static and dynamic video_generate schema
and from xai_video_edit / xai_video_extend; a `model` smuggled into the call is
ignored and the configured `video_gen.model` (then the provider default) is what
reaches the request. Config-side selection (`video_gen.model`,
`video_gen.<provider>.model`, `<PROVIDER>_VIDEO_MODEL`) is unchanged, and the
xAI plugin's explicit-model branch is no longer reachable from the tool layer.

Refs #83080

Subject: [PATCH 194/240] fix: let CodexAppServerSession resume a stored codex
 thread
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add ``resume_thread_id`` to CodexAppServerSession: when set, the first
ensure_started() issues ``thread/resume`` (with the same cwd / personality /
developerInstructions / model params thread/start sends) instead of starting
an empty thread, and verifies codex handed back the requested id. A refused
or mismatched resume raises the typed CodexThreadResumeError once; the next
ensure_started() falls through to ``thread/start`` on the same handshaken
client (initialize now runs once per client, not once per attempt).

Why: the thread id lived in memory only, so every new AIAgent for the same
Hermes session — a later API-server request or the first turn after a
restart — started a fresh codex thread and the model lost its own memory of
the conversation (#100531). The runtime decides the fail-closed policy; this
adapter only speaks the wire contract (verified against codex-cli 0.147.0:
thread/resume{threadId,...} -> result.thread.id; unknown id -> -32600 "no
rollout found"; killed writer -> -32600 "already has an active writer").

Salvaged from #103352 (thread/resume + id cross-fill + mismatch guard).

From e77e24a6a650abe1882449dc94aaf8ffe1594768 Mon Sep 17 00:00:00 2001
From: teknium1 <127238744+teknium1@users.noreply.github.com>

Subject: [PATCH 195/240] fix: persist the codex thread id per session and
 thread/resume it across an API-server restart
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After a codex app-server turn's projected rows are durable in the session DB,
store the codex thread id as ``codex_thread_id`` in the session row's
model_config (atomic merge via patch_session_model_config; never for a retired
thread). The FIRST CodexAppServerSession an AIAgent builds for that session
passes the stored id as resume_thread_id, so a rebuilt agent — the next
/api/sessions/{id}/chat request, or the first turn after the API server or
gateway restarts — resumes the model-side thread before turn/start instead of
starting an empty one while Hermes' own transcript continues.

Fail closed when codex cannot hand the thread back (rollout gone, CODEX_HOME
changed, previous app-server killed mid-write): drop the stored id, start a
fresh thread on the same client, and say so once —
"Codex thread could not be resumed; starting a new one." — through
_emit_diagnostic_status, the lifecycle status rail every surface renders (CLI
vprint, TUI/Desktop and gateway status_callback). No other lifecycle change:
a retired or prompt-recreated session in the same process keeps today's
fresh-thread behaviour and overwrites the binding once its turn commits.

Why: CodexAppServerSession kept the thread id in memory only, so every
API-server restart (and every per-request agent) silently reset the model's
memory of the conversation (#100531). Supersedes the persistence half of
#100528 (_persist_projected_messages now reports durability) and the
refuse-and-raise policy of #103352 with the maintainer-approved bounded slice.

@@ -470,6 +470,7 @@ Known limitations:
 - **No inline patch preview in approval prompts when codex doesn't track the changeset.** Codex's `fileChange` approval params don't always carry the changeset. Hermes caches the data from the corresponding `item/started` notification when possible, but if approval arrives before the item has streamed, the prompt falls back to whatever `reason` codex provides.
 - **`fallback_providers` fail over only on quota and rate-limit failures.** When a codex app-server turn fails with a billing / usage-limit / rate-limit error, Hermes switches to the configured [fallback provider](./fallback-providers.md) and retries the same turn on it; auth failures (`codex login` expired), turn timeouts and unknown-model errors do not fail over on this runtime and surface as the turn's error instead.
 - **Conversation history is not projected into the codex thread.** The codex thread receives Hermes' system prompt when it starts plus each new user message; prior Hermes history (e.g. from a resumed session) is not replayed into it. When the composed prompt changes mid-session (for example `/personality` in the TUI or Desktop), the next turn retires the running thread and starts a new one carrying the updated prompt; that new thread does not inherit the retired thread's history.
+- **The codex thread itself does survive a restart.** After each committed turn Hermes stores the codex thread id on the session row (`codex_thread_id` in the session's `model_config`, `hermes sessions` / `state.db`). The next agent built for that same Hermes session — a later `/api/sessions/{id}/chat` request, or the first turn after the API server or gateway restarts — issues `thread/resume` for the stored id before `turn/start`, so the model keeps its own memory of the earlier turns even though Hermes never replays its transcript. When codex cannot hand the thread back (its rollout was deleted, `CODEX_HOME` changed, the previous app-server was killed while still writing it), Hermes fails closed: it drops the stored id, starts a fresh thread and shows one line — `Codex thread could not be resumed; starting a new one.` — on the status rail of the surface you are on (CLI, TUI/Desktop, messaging gateway). A `/new` session never resumes an older thread.
 - **Sub-second cancellation isn't guaranteed.** Mid-stream interrupts (Ctrl+C while codex is responding) are sent via `turn/interrupt`, but if codex has already flushed the final message, you get the response anyway.
 
 If you find a bug, [open an issue](https://github.com/NousResearch/hermes-agent/issues) with the output of `hermes logs --since 5m`. Mention `codex-runtime` in the title so it's easy to triage.

Subject: [PATCH 196/240] fix(aux): provider "openai" resolves the same on the
 runtime and aux-client paths
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

auxiliary.<task>.provider: openai was expanded to custom + the user's OpenAI
endpoint only by agent/auxiliary_client.py (compression, vision, title
generation). hermes_cli/runtime_provider.py::resolve_runtime_provider — the
path background_review, curator, MoA slots and delegation use — had no such
expansion, so "openai" hit auth.resolve_provider's registry lookup and raised
"Unknown provider 'openai'". The alias table now lives once in
runtime_provider_custom.py (the direct-alias/custom sibling) and both paths
call it; resolve_runtime_provider applies it before the ladder.

_host_gated_env_key_candidates also pairs OPENAI_API_KEY with a base_url that
is exactly OPENAI_BASE_URL: the alias lands on that proxy when no block
base_url is set, and the key was issued for it — the host gate otherwise sent
the "no-key-required" placeholder there while the aux-client path used the key.

Slim redo of #116083 (same direction: shared alias, applied in the runtime
resolver) without the extra key gate and effective_provider threading.

Subject: [PATCH 197/240] fix(background_review): say so when the configured
 review route falls back to the main model
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_resolve_review_runtime swallowed every resolver error at DEBUG and returned
the parent runtime, so a dead auxiliary.background_review block ran reviews on
the main model indefinitely with nothing in agent.log and nothing on screen
(#116055: the configured model appeared zero times in session_model_usage).
The fallback now logs a WARNING naming the provider, model and reason on every
review and pushes the same message once per agent through _emit_warning — the
rail every surface (CLI, TUI/Desktop, gateway) already renders for the
reasoning_effort notice. curator and the MoA slot resolver had the identical
debug-only swallow; both are WARNING now.

Subject: [PATCH 198/240] feat(doctor): resolve every routed auxiliary.<task>
 block and report the dead ones
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

hermes doctor validated model.provider but never the auxiliary blocks, so a
task whose provider could not be resolved (and therefore silently ran on the
main model) passed as healthy. The config check now runs each routed block
through resolve_runtime_provider — the entry point the tasks themselves use —
and turns a resolver error into a finding with the resolver's reason; the
green line shows the resolved provider@host so a block that fell to the public
default endpoint is visible too. Docs: the openai direct-API alias, its
endpoint precedence, and the new warning/doctor behaviour.

+`provider: openai` is a direct-API alias: it routes through the custom endpoint at the block's `base_url`, else `OPENAI_BASE_URL`, else `https://api.openai.com/v1`, authenticated with `api_key` or `OPENAI_API_KEY`. Every auxiliary task resolves it the same way — `compression`/`vision`/`title_generation` as well as `background_review`, `curator` and MoA slots — so removing `base_url` while keeping `provider: openai` moves that task to the public OpenAI endpoint. A `providers.openai` entry in your `providers:` dict takes precedence and keeps its own endpoint and key.

Subject: [PATCH 199/240] feat(agent): bounded auto-recovery ladder after
 retries and fallback are spent (#85426, #107307)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When api_max_retries and the fallback chain are both exhausted on a transient
outage (5xx, overloaded/529, connect/read timeout) and no answer text has been
delivered yet, the turn used to end with "API failed after N retries" even
though the provider would be back a minute later, leaving the user to notice
and re-send. settle_unrecovered_error now hands that case to
agent/turn_recovery_autorecover.py: up to agent.auto_recovery_cycles (default 5)
wait-and-retry cycles on a jittered 15/30/60/60/60 s schedule, a provider
Retry-After winning up to 120 s, each cycle announced on the status rail AND
the live wait line ("Provider temporarily unavailable — retrying automatically
in Ns (cycle k/5); press Esc to stop", with a per-surface stop hint) plus a
log line for cron. The interruptible wait is the existing one, so Esc/stop
cancels cleanly and a steering correction still rebuilds the turn.

Fallback stays first: the ladder engages only when _try_activate_fallback has
nothing left. Overload-class errors ride this schedule instead of growing a
separate overload backoff path (#107307). Non-retryable classes never enter
because they exit through the client-error branch above. TurnRetryState
carries the cycle counter; jittered_backoff supplies the schedule — no second
retry framework.

Credit: @MilevskyYakov's #85441 established the shape (reuse
try_recover_primary_transport / jittered_backoff / TurnRetryState, interrupt
mid-wait, never replay delivered text); this lands it at the exhaustion seam
main has today with a bounded default.

 `agent.max_turns` is **unlimited by default** — the turn cap caused more problems than it solved (silent mid-task truncation), so out of the box Hermes runs a conversation turn to completion. To impose a cap, set a positive integer. To be explicit about "no limit", any of these case-insensitive spellings work: `"none"`, `"null"`, `"unlimited"`, `"infinite"`, `"infinity"`, `"inf"`, `0`, `-1` (they resolve to a `sys.maxsize` sentinel so the loop never exits on a turn count).
@@ -1216,6 +1217,8 @@ agent:
 
 `agent.api_max_retries` controls how many times Hermes retries a provider API call on transient errors (rate limits, connection drops, 5xx) **before** fallback-provider switching engages. The default is `3` — four attempts total. If you have [fallback providers](./features/fallback-providers.md) configured and want to fail over faster, drop this to `0` so the first transient error on your primary immediately hands off to the fallback instead of churning retries against the flaky endpoint.
 
+`agent.auto_recovery_cycles` is the safety net *after* both the retries and the fallback chain are spent. When the failure is a transient outage (HTTP 5xx, an `overloaded`/529 response, a connect or read timeout) and no answer text has reached you yet, Hermes does not end the turn with "API failed after N retries" — it waits and tries again, up to this many cycles (default `5`), with a jittered 15/30/60/60/60 s schedule. A provider `Retry-After` header wins over the schedule (honoured up to 120 s). Every surface shows the same line while it waits — `⏳ Provider temporarily unavailable — retrying automatically in 30s (cycle 2/5); press Esc to stop` on the CLI/TUI/Desktop, a status bubble on messaging platforms (`send /stop to cancel`), a `hermes.status` SSE event on the API server, and a log line for cron jobs. Pressing Esc (or `/stop`) cancels the wait immediately. Fallback still comes first: with a fallback chain configured, exhaustion moves to the next provider as before, and the ladder only engages once the chain has nothing left. Authentication, billing, request-format, entitlement and content-policy errors never enter the ladder. Set `0` to disable it.
+
 ## Wall-Clock Run Budget
 
 Separate from the iteration budget, you can give each conversation run an optional **wall-clock** budget. This is designed for one-shot and eval-harness invocations that run under a hard external ceiling (e.g. a 900-second per-task limit): without it, a run can time out with the work essentially done — one generation short of emitting the final answer, or stuck in a single hung provider call.

Subject: [PATCH 200/240] feat(api_server): stream agent status lines as
 hermes.status SSE events

The OpenAI-compatible SSE writers carried tool progress and reasoning but no
lifecycle status, so an API client waiting through a provider outage (now the
auto-recovery ladder) saw a silent socket with no way to tell "waiting on the
provider" from "hung". _spawn_stream_agent wires status_callback into the
agent and both writers (/v1/chat/completions, /v1/responses) emit
`event: hermes.status` with {kind, text}, redacted like every other API-bound
error text. The Responses writer's tag dispatch moves to a table so the new tag
does not grow an if/elif ladder.

Subject: [PATCH 203/240] refactor(compression): dedupe the actionable-user row
 test, skip an unread scan
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to the oversized-turn exception merged in #116181.

- `_find_last_user_message_idx` and `_real_user_indices_desc` each spelled out
  the same actionable-and-not-synthetic predicate; both now call one
  `_is_real_user_turn`. No behaviour change — same two classmethods, same rows.
- The newest-user index is only read by the split exception, which rolling
  micro-compaction disables, so the scan is skipped on that pass instead of
  running and being discarded.

`_is_actionable_user_turn` / `_is_synthetic_compression_user_turn` are pure, so
the dedupe is equivalence by construction; the row set each scan returns is
unchanged.

Subject: [PATCH 204/240] refactor(compression): finish the row-test dedupe and
 drop a gate that saved nothing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two corrections to 0b9a9a0f5c.

The `if allow_split_turn else -1` gate did not skip the scan it claimed to:
`_ensure_last_user_message_in_tail` runs the identical lookup as its first
statement, so the micro-compaction pass paid the same scan and the batch path
paid it twice. Reverted to the unconditional call, which also removes the `-1`
sentinel every reader had to reason about.

The dedupe stopped at two of five spellings of the same predicate. Three more
sites inline it: the in-flight replay's "a real request follows the summary"
check, the handoff-candidate admission test (as its negation), and the merge
pre-check. All now call `_is_real_user_turn`. The one remaining inline pair is
deliberately different — it also requires `_is_real_user_message`, which rejects
metadata-flagged scaffolding this predicate cannot see.

Equivalence: all three predicates are pure, so the negated and reordered forms
are the same test; 221 tests pass across the compressor/anchor/micro-compaction
files, including the source-shape anchor-order test that the call shape here
leaves untouched.

Desktop lint: /<script[\s\S]*?<\/script>/gi in a feed sanitiser scored as
'script injection' and failed pinned-source-validate for rss-reader. Mask
JS regex literals for the markup-shaped rule only; <script in a string
literal (an innerHTML payload) and createElement('script') still fail.

Install scanner: "printenv" as a whole-string entry of a read-only
allowlist (frozenset({..., "printenv"})) fired dump_all_env high →
caution on hermes-jev. Extend the literal-token demotion: a token that is
the ENTIRE quoted literal on a line that executes nothing steps down like
an alternation member; "sudo" inside subprocess.run([...]) and
os.system("printenv") keep high.

A/B vs origin/main: attack probes identical (23 rows), in-tree sweep 319
entries 0 worse/0 changed; both new tests red on base. Bumps
PLUGIN_SCANNER_VERSION to v6 so cached caution verdicts refresh.

Subject: [PATCH 206/240] fix(gateway): distinguish interrupted and unreachable
 model connections

Split the single connection row of the gateway's shaped provider-error reply
into three: an interrupted established connection (reset/EOF/RemoteProtocolError),
a refused/unroutable endpoint (the case #86570 wrote the "not running or is
unreachable" wording for), and a cause-free SDK ``APIConnectionError`` that
supports neither diagnosis. A reset says nothing about whether the endpoint is
up, so telling the user to restart a server that just answered sends them to
debug the wrong thing (#116323).

Selectively adapted from Lei-k/hermes-agent#16 (497cc47556b1) via PR #109701,
rebased onto the current reply contract (rate-limit > auth > policy > connection,
every reply names a slash command, no operator jargon).

Subject: [PATCH 208/240] docs: explain the three gateway connection-failure
 replies

The chat reply now differs for an interrupted connection, a refused/unroutable
endpoint and a cause-free SDK connection error; the FAQ names each wording and
what to do about it so a user reading one on Telegram/Discord/Slack knows
whether to restart the model server or just /retry (#116323).

 **Solution:** if the request is large (hundreds of KB — long coding sessions reach this once the context grows) and short new chats work, the endpoint or a proxy in front of it is likely rejecting bodies that size: raise its body limit, or run `/compress` to shrink the context. If the request is small, the endpoint is unreachable — check the `base_url`, then retry with `/retry`. `logs/agent.log` records the exception chain for each attempt.
 
+#### Messaging replies: "interrupted mid-request" vs "not running or is unreachable" vs "could not reach"
+
+Chat surfaces (Telegram, Discord, Slack, …) never show the raw transport exception; the gateway maps it to one of three short replies, and the difference tells you where to look:
+
+| Reply | What happened | What to do |
+|---|---|---|
+| "The connection to the AI model service was **interrupted mid-request** — usually transient." | An established connection was cut (`Connection reset by peer`, EOF, `RemoteProtocolError`). The endpoint answered the connect, so it is running. | `/retry`. If it recurs on large requests, see the "stream" entry above. |
+| "The AI model service isn't reachable right now — the configured model endpoint is **not running or is unreachable**." | Nothing accepted the connection (`Connection refused`, no route to host, DNS failure). | Start the model server / check `base_url`, then `/retry`; `hermes doctor` on the host. |
+| "Hermes **could not reach** the AI model service (no further detail from the SDK)." | The SDK reported a generic `APIConnectionError` and kept no cause; neither of the above is certain. | `/retry`; `hermes doctor` if it persists. The raw exception is in `hermes logs`. |
+
 #### `/model` only shows one provider / can't switch providers
 
 **Cause:** `/model` (inside a chat session) can only switch between providers you've **already configured**. If you've only set up OpenRouter, that's all `/model` will show.

Subject: [PATCH 209/240] fix(plugin-catalog): re-pin
 hermes-project-stewardship to 4f733a8

The pin merged in #115599 (eb1ac9b) carries a security gap found during that
review: the run_command_evaluator capability was never consulted, because
AutonomyPolicy was never constructed anywhere in src/. A project at autonomy
level 0 still executed command-type objective evaluators, since the security
allowlist constrains which executable may run and never whether running is
permitted at all.

4f733a8 wires the policy in and fails closed below level 3.

Verified at the new sha against a clean NousResearch/hermes-agent main
checkout: doctor_plugin ok with no findings, read_declaration resolves both
deps from pyproject. Upstream repo gates all pass.

 description: 'Hosted Corpus MCP (Streamable HTTP at corpuslaw.us/api/mcp) plus two bundled
   skills: US law search/get_node/list_coverage over 571k+ provisions, and LLC/nonprofit
   formation intake (requirements, compare, NAICS lookup, handoff, USDC checkout,
   payment_status), with account.status for quota. Filing always stays human-gated and
   USDC pay is email-confirmed. Portable Agent Plugins v1 package (mcp.json + skills/);
-  no API key needed for anonymous research.'
+  no API key needed for anonymous research. The formation skill requires fixed
+  vendor-authored marketing copy in the first reply and before payment, and sends
+  founder PII (name, email, phone, address) to Corpus through links and MCP tools.
+  Intake instructions are vendored; checkout requires exact-amount confirmation
+  from the user in the current turn.'

Subject: [PATCH 236/240] feat(catalog): add hermes-structured-aux-models
 plugin entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds one plugin-catalog entry for trajectoire-ai/hermes-structured-aux-models,
a `kind: model-provider` plugin that registers the `structured-aux` provider.

The plugin accepts the OpenAI-shaped `chat.completions.create()` call Hermes'
auxiliary client makes and translates it into a bounded Jev decision request on
OpenRouter, mapping the typed answer back — so auxiliary tasks (approval, MCP
sampling, compression) get a bounded decision instead of a free-form chat
prompt. It fails open: any request it cannot express as a decision raises, so
Hermes falls back to the operator's own auxiliary provider.

- tier: community, category: models
- pin: e5c49b081ad04adca2ee3edc601b09ede6cee4c5 (v0.1.0, repo released)
- capabilities: no tools, hooks or middleware registered; no required env vars
  (the OpenRouter credential resolves env -> profile .env -> Hermes credential
  pool, so no duplicate secret is demanded at install time)
- requires_hermes: ">=0.21" — the plugin seams were verified against v0.21.0

Verified locally against the admission gate at the pinned sha:
`python3 scripts/validate_plugin_catalog.py plugin-catalog/` -> OK: 187 files valid
`hermes plugins validate --install-deps <dir>` -> Validation passed (13/13 checks,
security scan: safe, capability probe: registered provider structured-aux)

Subject: [PATCH 240/240] fix(plugin-guard): plural test-file names and
 delegation prose are not attack shapes

Two install-scan false positives from catalog intake, each red on the real pinned tree:

* memory-review (apoapostolov/hermes-agent-awesome-plugins@b270520, plugins/memory-review):
  tests_state.py:86 holds '/etc/passwd' in a quoted traversal-probe list and scored
  system_passwd_access:critical -> dangerous (unoverridable). The test-tree name rule only knew
  test_*.py / *_test.py; a single-module plugin without a tests/ dir names its file tests_*.py.
  Accept the plural prefix/suffix so the quoted fixture is a note, exactly as tests/test_x.py is.
* pstack (Cloeille/pstack@ac5e5ab, #116381 pin): skills/poteto-mode/SKILL.md:128
  'Send subagents the minimum context they need' hit context_exfil:high. Handing context to the
  agent's own subagent is an in-process handoff; the bare-'context' branch now skips a
  subagent/worker/delegate recipient named right after the verb. External destinations, bare
  'your context', and 'send agents your context' still match.

Two tightenings guard the widened test-file surface (both pre-existing gaps, now closed):
  - _EXEC_ON_LINE gains open(: open('/etc/passwd') in a test steps down once (high, confirmable)
    instead of reading as quoted data (medium, note).
  - the JS regex-literal lexer accepts only real flags [dgimsuvy]; with [a-z]* an unquoted Unix
    path lexed as /etc/ + flags 'passwd', so 'cat /etc/passwd | curl ...' in a test script was inert.

PLUGIN_SCANNER_VERSION plugin-guard-v6 -> v7 so cached verdicts re-scan.
