The retained comment still claimed a scope-less multiplex caller could load an
OSS config; identity reads above it raise UnscopedSecretError first. Both the
comment and the regression test now say the same thing: callers are scoped, an
OSS profile whose scope lacks MEM0_API_KEY initializes, and a scope-less caller
is a spawn-site bug that raises.
Four bundled plugins wrapped get_hermes_home() in a try/except that fell back
to ~/.hermes on ImportError (a2a/protocol._hermes_home, photon/auth
._auth_json_path, google_chat adapter inline, openviking done in the previous
commit). A bundled plugin cannot lose hermes_constants -- each already imports
gateway.* / agent.* from the same tree -- so the fallback was dead code that
was also wrong on Windows (%LOCALAPPDATA%/hermes) and under a profile override.
telegram's gmail-triage verb path used Path.home()/".hermes" outright, ignoring
profiles. mem0/_oss_providers baked os.path.expanduser("~/.hermes/mem0_qdrant")
into VECTOR_PROVIDERS at import time, so the Qdrant default landed in the
user's ~/.hermes for every profile; the default is now a lazy callable resolved
by vector_default_config(provider_id) at setup time. a2a/security.py only
changes its import (it borrowed protocol._hermes_home).
Behavior change: on Windows and under profiles these paths now follow the
active HERMES_HOME (they were previously anchored to ~/.hermes in the impossible
fallback / at import time); the default-profile POSIX layout is unchanged.
Test: tests/plugins/test_plugin_paths_follow_profile.py asserts each resolver
(a2a conversations, photon auth.json, mem0 qdrant default, openviking log)
lands inside a HERMES_HOME ContextVar override; sabotage red for the mem0
import-time constant and the photon ~/.hermes fallback.
Three shims caught UnscopedSecretError and degraded to "" (mem0._scoped_env)
or to os.environ (langfuse._secret, azure_identity_adapter._scoped_env). Under
multiplex os.environ holds the DEFAULT profile's .env, so the langfuse/azure
fallback could ship another profile's keys, and the mem0 fallback silently
routed a mis-spawned turn's memories into the default profile's account. The
exception exists to surface exactly that spawn-site bug (agent/AGENTS.md:
never add environ fallthrough, never swallow it). All three now call
agent.secret_scope.get_secret directly: with a scope installed a miss returns
the default; single-profile deployments (multiplex off) still read the process
env inside get_secret; a scope-less multiplex caller raises.
Behavior change: a mis-spawned child under gateway.multiplex_profiles now
fails loud with UnscopedSecretError instead of running silently unauthenticated
/ on the default profile's identity. The #99121 contract (OSS mode needs no
MEM0_API_KEY in scope) is unchanged and its test now installs an empty profile
scope, which is the situation the issue described; a genuinely scope-less
caller is asserted to raise in a new test.
Tests: tests/plugins/test_scoped_secret_readers_fail_closed.py (scope wins over
environ; scope-less multiplex raises) for langfuse + azure, sabotage red when
the langfuse fallthrough is restored; tests/plugins/memory/test_mem0_v3.py::
test_load_config_fails_closed_without_scope_even_for_identity_settings,
sabotage red with a swallowing wrapper reinstated.
Six of eight memory providers spawned plain threading.Thread for prefetch/sync/
writer work. A plain thread starts with an EMPTY contextvars.Context, so under
multiplex profiles the worker resolved the DEFAULT profile's HERMES_HOME (and
fails closed on scoped secrets). honcho and hindsight had each noticed and
written their own copy_context() wrapper; core had a third in memory_manager.
One canonical pair now lives on the ABC module every provider already imports:
agent/memory_provider.py::ctx_bound / spawn_context_thread. memory_manager,
honcho, hindsight, mem0, retaindb, byterover, supermemory and openviking all use
it; the honcho and hindsight wrappers and memory_manager._ctx_bound are deleted.
Five "json.loads(path.read_text()) or {}" readers (mem0._read_mem0_json,
honcho client/oauth/cli _read_config, hindsight save_config/_load_config) fold
into utils.read_json_or_empty, the read half of every read-merge-atomic_json_write
sidecar store.
holographic.save_config was the only config.yaml writer in the tree that
bypassed hermes_cli.config.save_config: raw open("w") + yaml.dump with no config
lock, no managed-mode refusal, no atomic replace, and a swallowed exception. It
now calls save_config(..., merge_existing=True). Behavior change: a managed
install refuses the write (previously silently rewrote config.yaml); other
sections are deep-merged instead of round-tripped through a raw dump.
openviking._hermes_home_path guarded an impossible ImportError of
hermes_constants (the module already imports agent.*) with a ~/.hermes fallback
that is wrong on Windows and under profile overrides; it is replaced by
get_hermes_home() directly.
Tests: tests/plugins/memory/test_provider_threads_inherit_profile.py drives each
provider's real spawn path with a fake backend and asserts the thread sees the
spawner's HERMES_HOME override (sabotage: retaindb back on threading.Thread ->
red). tests/plugins/memory/test_holographic_save_config.py pins merge-with-
existing-sections and managed-mode refusal (sabotage: raw yaml.dump -> red).
Six independent line-parsers with three different quoting/comment semantics
read the same .env files: tools/skills_tool.load_env (strip("\"'"), no inline
comments), hermes_cli/managed_scope._parse_env (same, no export, no BOM),
web_server_cron._profile_env_value (plain utf-8, no BOM), profile_cmd
._env_file_has_key, env_loader._env_keys_defined_in_dotenv (utf-8, so a BOM'd
first key stayed "\ufeffKEY" and the dashboard profile scrub missed line 1),
mem0/_setup._prompt_api_key (startswith scan, no quote strip). The boundary
parsers (scrub key set, skill secret capture) therefore disagreed with the
parser that installs the profile scope.
Now every one is a 1-3 line forwarder onto load_env_file, and
hermes_cli.config.load_env is memo over it (public signature unchanged).
_parse_env_value moves next to its only caller in secret_scope.
load_env_file gains the same latin-1 fallback env_loader uses to install
into os.environ, so a mis-encoded file yields the same key set on both sides.
Managed .env keeps its fail-LOUD contract (decode error logs and ignores the
file) instead of load_env_file's fail-soft {}.
Behavior change: managed .env, skills_tool and mem0 setup now honour
`export`, quoted-value escapes and inline comments the way the profile scope
does; web_server_cron and the dashboard scrub tolerate a BOM.
Invariant test: a BOM'd/export/quoted/commented .env yields the same key set
via load_hermes_dotenv (installer), load_env_file (scope) and
_env_keys_defined_in_dotenv (scrub); fails with the old scrub parser.
_truncate_for_sync documents "the last sentence boundary within max_len", but it
looped over separator KINDS and returned on the first kind that qualified. An early
"。" therefore outranked a "." 240 characters later, and in pure ASCII "." outranked
a later "!" or "?" purely because it comes first in the tuple.
With the 450-char default, "a"*200 + "。" + "b"*240 + "." + "c"*100 kept 201 of the
442 characters available: 241 characters the embedder would have accepted were
discarded, so any fact in the second half of the turn never reached extraction. The
add() call succeeds, so unlike #106235 nothing is logged — the turn is simply
remembered from its first sentence. Raising sync_max_chars widens the gap rather
than closing it.
Take the max over every separator instead, from a named tuple so the set is not
buried in the loop. ".\n" is dropped: its index can never exceed the bare "." it
starts with, so under a max it is unreachable. The first-third guard and the hard-cut
fallback for unsegmented input are unchanged.
Fixes#108868
Under gateway.multiplex_profiles, os.environ holds the DEFAULT profile's .env; a
secondary profile's values exist only in the per-turn secret scope. Every reader
below still read os.environ/os.getenv at call time, so a secondary profile's turn
silently used the default profile's value.
Credentials (F6): FIRECRAWL_API_KEY (read_file hosted OCR), OPENVIKING_API_KEY,
mem0-OSS OPENAI_API_KEY, MODAL_TOKEN_ID/SECRET and BROWSER_USE_API_KEY presence
gates, and the xAI video plugin's os.getenv("XAI_API_KEY") fallback AFTER the
scoped resolver had already missed — the exact fallback-after-miss shape
gateway/AGENTS.md forbids. Deleted, not re-scoped: the resolver is the scope.
Identity / tenant (F7): MEM0_USER_ID/AGENT_ID/HOST/MODE, SUPERMEMORY_CONTAINER_TAG,
RETAINDB_PROJECT, OPENVIKING_ACCOUNT/USER/AGENT (and the whole layered() env
read), HINDSIGHT_BANK_ID/MODE/retain shaping, HERMES_HONCHO_HOST. A raw read
put a secondary profile's memories into the default profile's account/bank/
project/tenant and recalled them back into the default's turns. Each now uses
get_secret with the provider's own per-profile default on a miss.
Endpoints (F8): OPENAI_BASE_URL (aux custom runtime + direct-alias expansion),
XAI_BASE_URL/HERMES_XAI_BASE_URL (aux OAuth), NOUS_INFERENCE_BASE_URL (#65941,
both the aux builder and hermes_cli.auth_nous._nous_inference_env_override),
GATEWAY_PROXY_URL (same UnscopedSecretError-only fallback shape as
GATEWAY_PROXY_KEY three lines below), FIRECRAWL_API_URL, BROWSERBASE_BASE_URL,
SUPERMEMORY/RETAINDB/HONCHO/HINDSIGHT URLs. The keys beside them were already
scoped, so a secondary's key was sent to the default profile's proxy or host.
Targets / display (F11): WEIXIN_HOME_CHANNEL (message posted into the default's
chat), HERMES_LANGUAGE, and agent/i18n's process-wide lru_cache of
display.language — now keyed by HERMES_HOME.
Outbound webhooks: hooks.outbound[].secret_env resolved from os.environ while
the gateway registers each profile's targets inside that profile's scope, so a
secondary's deliveries were signed with the default's secret or left unsigned.
Agent-cache eviction: _spawn_release_thread started a bare threading.Thread, so
commit_memory_session -> provider on_session_end ran with an EMPTY context. The
thread now runs copy_context() and, for the unscoped housekeeping sweep, enters
the owning profile's _profile_runtime_scope resolved from the session key
(agent:<profile>:...). The pressure batch does the same per key.
session_search (#82903): agent/inline_tool_executors.py::_session_search
forwarded every schema argument except `profile`, so a gateway agent could
never select a named profile's store. Forwarded; the ownership-scoping design
in #87779/#87847 is a separate design call and is not attempted here.

Conflict resolution on top of main also routes MEM0_MODE / MEM0_HOST / MEM0_AGENT_ID /
MEM0_USER_ID through get_secret: identity and host are .env values like the key, and a
raw environ read hands a secondary profile the default profile's mem0 account.
(cherry picked from commit 7a5863ebafdb193d8ec2f89a7aca309774d6d69a)
A flat 450-char cap fits 512-token embedders (bge-small-zh-v1.5,
all-minilm) but stores only ~5% of the window on 8192-token models
(text-embedding-3-small, jina-embeddings-v3, bge-m3), degrading memory
quality for users those models served fine before truncation existed.
Read `sync_max_chars` from mem0.json once in initialize() (450 default)
and pass it to _truncate_for_sync(). Config over auto-detection: the
Ollama /api/show probe + known-model table proposed in #37427 adds a
network call and a curated list for a number the operator already knows
from their embedder choice; the setup wizard's mem0.json is the plugin's
behavioral-settings surface (no new HERMES_* env var). Documented in the
plugin README and the memory-providers docs page.

sync_turn() sent the whole turn to backend.add() untruncated. OSS
embedding models with small context windows (Ollama bge-small-zh-v1.5:
512 tokens) reject the request with HTTP 500, and hosted APIs answer
INPUT_TOKEN_LIMIT_EXCEEDED — in both cases _try() only logs, silently
dropping the turn's memory extraction after long conversations.
Cap each synced message at its last sentence boundary within 450 chars
before ingestion: short turns pass through unchanged, long turns keep a
coherent statement for fact extraction. This replaces the previous
retry-on-error approach, which could not match Ollama's HTTP 500 shape.
Salvaged from #37427 with the test suite trimmed to the one invariant
(oversized turn still reaches a small-context backend, short text
untouched, no breaker failure).

The plugin loader pre-registers empty shells in sys.modules before
executing any submodule. When _setup.py ran 'from . import _read_mem0_json'
at module level, Python found the empty parent shell (init not yet executed),
so the import failed silently. This left _setup.py partially loaded and
post_setup undefined, causing 'cannot import name post_setup' during
hermes memory setup mem0.
Move the import inside the three functions that use it, matching the
late-import pattern __init__.py already uses for post_setup.
Fixes: hermes memory setup mem0 crashing with ImportError
Review findings on #102117 (independent reviewer + itsflownium):
* hermes_cli.kanban_db.connect / connect_closing pointed at hermes_cli.projects_db (different DB, no
board= parameter). The compat generator ranked candidate homes by path proximity when a name is
defined in several modules. Now it requires shape compatibility with the BASE definition (same
literal for constants, superset of parameter names for defs) and prefers the facade's own
<stem>_* sibling. Same class fixed for tools.tts_tool.DEFAULT_XAI_BASE_URL (-> tts_tool_providers),
and 17 constants/defs that had been pointed at same-named strangers (Matrix MAX_MESSAGE_LENGTH ->
Signal's 8000, tts MAX_TEXT_LENGTH -> BlueBubbles', honcho/retaindb/supermemory *_SCHEMA -> another
plugin's schema, ...) are now restored from BASE verbatim instead.
* send_yuanbao_direct (restored-def): body called adapter._outbound.send_direct, which HEAD moved to
the sender; rewritten to adapter._outbound.sender.send_direct.
* COMPAT_MANIFEST.md states the scope explicitly: public top-level names only; private names and
test monkeypatch seams are not preserved.
* scripts/check_subprocess_stdin.py: _splat_carries_stdin looked 30 lines ahead in the file text
and was satisfied by an unrelated later stdin=; it now finds the splatted name's definition via AST
and requires stdin inside that expression/body.
Tests: tests/test_compat_manifest_targets.py (pointer identity vs the facade's sibling; kanban
connect(board=) opens a Kanban DB, not projects.db; both FAIL on the previous layer),
test_subprocess_stdin_guard gains the false-negative probe, and the MoA -Q quiet-output contract
tests are back (tests/agent/test_moa_quiet_reference_output.py) against build_moa_facade.
The Sep 2026 decomposition (PR #102117) makes internal import paths a non-API: names now live in
the focused modules that define them. This commit is the ONLY thing keeping the old paths alive,
so external plugins have time to update. It is deliberately a single, unsquashed commit:
git revert <this sha>
removes every shim, stub and manifest at once on the announced date. Nothing in-tree may depend on
these pointers: scripts/check_compat_pointers.py (wired into lint.yml) fails CI if it does.
What it adds (see COMPAT_MANIFEST.md, compat_manifest.json):
- 332 facade modules get one delimited `PLUGIN-COMPAT` block appended at the end of the file
- 1,172 moved names resolved lazily via a module `__getattr__` (PEP 562) — never a top-level import,
so no import cycles; facades that already had `__getattr__` get a chained one
- 592 third-party/stdlib names the old modules used to expose, with their original import statements
- 266 public definitions that had been deleted as unused, restored byte-for-byte from the pre-decomposition
tree (+40 private helpers and 16 imports pulled in only because a restored definition needs them)
- 3 deleted modules recreated as re-export stubs (gateway/startup_watchdog, hermes_cli/observability/
relay_runtime, tools/environments/modal_utils)
- private names (`_x`) get no pointer: they were never API (3,792 skipped)
Verified: all 335 touched modules import under a fresh HERMES_HOME and every manifest name resolves;
the lint reports zero in-tree uses; ruff clean; targeted suites unchanged.
Route HINDSIGHT_API_KEY/HINDSIGHT_LLM_API_KEY, HONCHO_API_KEY, SUPERMEMORY_API_KEY, MEM0_API_KEY and RETAINDB_API_KEY reads through agent.secret_scope.get_secret so multiplexed turns resolve the active profile's key instead of the process environment. Also guard supermemory post_setup's os.environ write on not is_multiplex_active() — writing one profile's key into the process-global env pollutes sibling profiles; the single-profile convenience path is unchanged.
Installing a memory provider (Honcho, mem0, hindsight, ...) from the
dashboard Plugins page failed on hosted deployments with a permission
error: the setup endpoint shelled out to
`uv pip install --python sys.executable`, which targets the sealed
read-only venv under /opt/hermes (immutable hosted image, NS-579/#49113).
The correct mechanism already exists: tools/lazy_deps.py redirects
installs to the writable durable target on the data volume
(HERMES_LAZY_INSTALL_TARGET=/opt/data/lazy-packages) when the venv is
sealed (HERMES_DISABLE_LAZY_INSTALLS=1), appends the target to the END
of sys.path (core venv always wins collisions), and constrains shared
deps to core-venv versions. The dashboard installer simply never used
it.
Fix:
- tools/lazy_deps.py: new public install_specs() — installs arbitrary
manifest-declared pip specs through the same environment routing as
ensure(): venv-scoped by default, durable-target on sealed images,
refused with an actionable reason when gated off (config kill switch
or sealed venv without a target — never surfaces raw EROFS/EACCES).
Specs are validated with _spec_is_safe(); post-install it invalidates
import/metadata caches so availability rechecks in the same process
see the new packages without a restart. Never raises.
- hermes_cli/web_server.py: _install_memory_provider_pip_dependencies
now calls install_specs() instead of building its own uv/pip
subprocess. Blocked installs surface the gate reason in the setup
results; the response's status block reflects post-install
availability (stale 'missing deps' state clears immediately).
- hermes_cli/memory_setup.py, plugins/memory/honcho/cli.py,
plugins/memory/mem0/_setup.py: CLI setup wizards routed through
install_specs() too — same sealed-venv failure mode, same fix.
No hosted setup path writes to /opt/hermes anymore; provider discovery
and installation now use the same environment (sys.path activation is
shared with the lazy-install bootstrap in hermes_bootstrap).
Tests:
- tests/tools/test_lazy_deps.py: TestInstallSpecs — gating matrix
(sealed+no-target blocked with immutable-deployment reason, config
kill switch, sealed+target proceeds), spec-safety rejection before
any subprocess, venv-scoped vs --target command display, failure
stderr passthrough, never-raises contract.
- tests/hermes_cli/test_web_server.py: setup endpoint routes pip
through lazy_deps (regression guard asserts no direct 'pip install'
subprocess), blocked-reason surfacing, same-response availability
recheck clears stale missing state.
Fixes NS-605 (Plain T-1111).
AST-driven pass over every Path.read_text()/write_text() without an
explicit encoding= across non-test code: 71 sites in 34 files
(skills_hub, hermes_cli/main+profiles+service_manager+container_boot,
mem0/hindsight/honcho plugins, achievements dashboard, release/CI
scripts, productivity+comfyui skill helpers, agent/*). Verified zero
positional-encoding collisions before insertion; per-file compile()
check after.
Adds a check-windows-footguns rule flagging bare single-line
read_text/write_text (multi-line forms stay covered by the AST guard
test from #38985). Together with the salvaged contributor commits this
retires the ~169-site bare file-I/O class (#37423's long tail).
Follow-up to review feedback:
- mem0 _prompt_api_key read .env with the locale default, so a Notepad
BOM hid the first key from the masked current-value lookup; read it
with utf-8-sig + errors=replace like the canonical readers in
hermes_cli/config.py.
- hindsight _load_simple_env used plain utf-8; it also parses the Hermes
.env during post_setup, where a BOM stuck to the first key. Switch to
utf-8-sig + errors=replace.
- Add hindsight regressions: BOM key matching in _load_simple_env and in
the cloud post_setup writer, plus non-ASCII round-trip preservation,
and a mem0 regression for the BOM'd masked-key lookup. The BOM tests
fail without the fix on any platform.

The mem0 and hindsight memory-provider setup routines round-trip the
user's ~/.hermes/.env: they read existing lines, update the keys they
manage, and rewrite the whole file preserving every other line verbatim.
Both used env_path.read_text() / write_text() with no encoding.
read_text()/write_text() with no encoding fall back to the system locale
(cp1252/GBK on Windows), so on a non-UTF-8 host the preserved lines get
mangled or the call crashes on any non-ASCII value, and — because the
reader never strips a BOM — a Notepad-edited .env makes the first key
fail the in-place match and get duplicated instead of updated.
Match the canonical .env readers in hermes_cli/config.py: read with
encoding='utf-8-sig' (BOM-tolerant) and write with encoding='utf-8'.
mem0/_setup.py already pins utf-8 for mem0.json, so this just aligns the
.env path in the same file. Fixes both memory plugins in one class fix.
Adds regression tests: a BOM'd .env updates the first key in place
(locale-independent, fails without the fix) and non-ASCII existing lines
survive the round-trip.

Path.read_text() without an explicit encoding uses the platform's
default encoding. On Windows this is typically cp1252 or mbcs, which
causes UnicodeDecodeError or silent data corruption when reading
UTF-8 content (JSON files, user text, config with non-ASCII chars).
This is the read-side companion to the write_text() encoding fix.
Fixed the most critical locations that read JSON data, user content,
and config files across 14 files with 31 call sites.
Pattern: .read_text() → .read_text(encoding='utf-8')
json.loads(path.read_text()) → json.loads(path.read_text(encoding='utf-8'))
On Windows with Chinese locale (GBK), subprocess.run(text=True) without
explicit encoding causes UnicodeDecodeError crashes. This fix adds
encoding='utf-8', errors='replace' to all subprocess.run() and
subprocess.Popen() calls that use text=True across 76 non-test Python files.
Fixes#53428 (master tracker for Windows GBK locale crash).

those will be submitted as separate focused PRs.
The salvaged SelfHostedBackend made self-hosted servers reachable via
mem0.json / MEM0_HOST, but the setup wizard still offered only Platform
and OSS — exactly the gap users hit (Discord report: 'At memory setup
there's only 2 options'). Adds a third wizard mode:
- interactive picker: Platform / Self-hosted server / Open Source
- non-interactive: hermes memory setup mem0 --mode selfhosted
--host http://... [--api-key ...] [--dry-run]
- host -> mem0.json (behavioral), API key -> .env as MEM0_API_KEY
(secret), optional key for AUTH_DISABLED servers
- best-effort reachability check against the server, non-fatal
- README + memory-providers docs updated with the wizard path
Review follow-ups on the salvage:
- get_all() pruned from the ABC and all three backends: mem0_list (its
only caller) was removed by the recall-tuning commit, leaving new,
tested, unreachable code — including SelfHostedBackend's _MAX_TOP_K
over-fetch workaround. Tests for it dropped; fake-class stubs remain
harmlessly. (The #52921 true-total fix lives on in the PR history if
a lister ever returns.)
- The persisted rerank config key was write-only (setup prompted for it,
nothing read it). initialize() now parses it into _rerank_default and
mem0_search uses it when the model doesn't pass rerank explicitly;
per-call args still win. Guard test added.
- Platform-mode setup now warns when MEM0_HOST is set in the environment:
the json host-clear can't help there (_load_config seeds host from the
env var, docs tell users to put it in .env) — the user would silently
keep routing to the self-hosted server.
- SelfHostedBackend: connect-level retries (httpx.HTTPTransport(retries=2))
so a single transient blip doesn't count toward the provider breaker;
transport now injectable and the test helper uses the real __init__
instead of mirroring it via __new__.
- plugin.yaml description no longer leads with reranking (off by default,
platform-only); docs em-dash typo fixed.
Follow-up on the salvaged #55614. The PR added host-based routing to
_create_backend (precedence: oss > host > platform) but two sibling surfaces
didn't mirror it:
- system_prompt_block() checked host before oss, so an oss+host config ran
OSS but told the model it was self-hosted HTTP. Reordered to match routing.
- Platform setup (hermes memory setup mem0 --mode platform) left a stale host
in mem0.json; since host beats platform, the user kept routing to the
self-hosted server. save_config merges (no delete), so clear host to ""
rather than pop() so the merge actually overwrites it.
Adds regression tests for both (mutation-checked).
Salvage of #55614 by @kartik-mem0 (mem0 maintainer). Adds a SelfHostedBackend
that talks to a self-hosted Mem0 Docker server over httpx (X-API-Key auth,
/search + /memories routes), gated behind `host`. Also folds in the mem0
research-team recall tuning that rides with it: rerank defaults to false across
all modes, the mem0_list tool is removed (5->4 tools), search guidance is
de-shouted, and self-hosted get_all reports the true stored total (#52921).
Supersedes the self-hosted portion of #52487 (@liuhao1024, first-submitted).

The supermemory and mem0 memory providers shipped third-party SDKs
(supermemory / mem0ai) that are not core dependencies, but — unlike the
honcho and hindsight providers — they imported those SDKs directly with
no tools.lazy_deps.ensure() preflight and had no LAZY_DEPS allowlist
entry. On the published Docker image the agent venv is sealed
(HERMES_DISABLE_LAZY_INSTALLS=1) and lazy installs are redirected to a
writable durable target (HERMES_LAZY_INSTALL_TARGET). honcho/hindsight
route through ensure() and install fine there; supermemory/mem0 never
called it, so their SDK was never installed on a hosted instance and the
provider silently reported itself unavailable even with the API key set.
Fixes:
- Add memory.supermemory + memory.mem0 to the LAZY_DEPS allowlist
(tools/lazy_deps.py), pinned to current PyPI releases.
- Call ensure('memory.<x>', prompt=False) at each SDK-import chokepoint
(_SupermemoryClient.__init__; Mem0MemoryProvider._create_backend),
mirroring honcho's wrapped try/except shape.
- Drop the SDK-import gate from supermemory's is_available() — it was a
chicken-and-egg trap (provider never loaded on a sealed venv, so
ensure() never ran). Now key-presence only, like honcho/mem0.
- Add matching pyproject extras [supermemory]/[mem0]; update the
lazy-covered-extras contract test (excluded from [all] by policy).
Tests prove each path fails without the fix and the real sealed-venv
durable-target gate accepts both features.
Follow-up to #53791 addressing review feedback: the footgun checker treated
capture_output=/stdout=/stderr=/check_output as proof a subprocess can't pop a
Windows console. That invariant is false — stream redirection controls where a
child's output goes, not whether a console is allocated. From a console-less
parent (Desktop/Electron, pythonw.exe, detached gateway/cron) a console-subsystem
child still flashes a window even when fully captured.
- check-windows-footguns.py: capture/redirect/check_output is no longer a blanket
safe-pass. Added _WINDOWS_FLASHING_PROGRAMS (git/gh/npm/node/python/uv/ffmpeg/
docker/powershell/…); calls to those are flagged even when captured. Non-flashing
programs keep the capture exemption (no 271-site noise). _subprocess_compat.run/
popen calls are inherently safe (wrapper injects CREATE_NO_WINDOW).
- Routed the 35 genuine flashing git/gh/npm/uv/ffmpeg/docker spawns through the
_subprocess_compat.run/popen chokepoint (Brooklyn's wrapper from #53810) — the
durable fix, not per-site annotations. cmd.exe /c start stays # ok (intentional).
- Updated tests + CONTRIBUTING.md rule #17 to the corrected invariant.
* fix(windows): stop subprocess console-window popups + add CI guard
The single biggest source of Windows 'terminal popup' bug reports was bare
subprocess.run/Popen calls spawning a console window. The compat helpers
(windows_hide_flags / windows_detach_popen_kwargs) already existed but the
footgun checker had no rule to stop new bare calls from reintroducing the flash.
- scripts/check-windows-footguns.py: new AST-based rule flagging subprocess
calls that can create a new console — output-redirection-aware (capture/
redirect/check_output exempt) and POSIX-only-program-aware (launchctl/
systemctl/brew/etc. exempt). Comprehensive on real popups, no annotation
burden on calls that can't flash.
- Swept all genuine window-spawning sites through windows_hide_flags()/
windows_detach_popen_kwargs(); marked intentionally-visible launches
(editor/terminal/foreground re-exec) with '# windows-footgun: ok'.
- tests/scripts/test_windows_footgun_subprocess_rule.py: behavior-contract
tests + full-repo cleanliness invariant.
- CONTRIBUTING.md: documents the rule + the helper pattern.
* test: accept creationflags kwarg in psutil_android fake_subprocess_run
The Windows no-window sweep added creationflags=windows_hide_flags() to
install_psutil_android.py's subprocess.run call; the test's fake stub had a
fixed (cmd) signature and raised TypeError on the new kwarg.
* fix: update to version 3 endpoints and adding update and delete tool
* chore: removing the test md file
* fix: prevent circuit breaker on client errors in Mem0 provider
* chore: add telemetry for platform version
* feat: add OSS mode support to Mem0 memory provider
* chore: bump mem0ai dependency to >=2.0.1 in memory plugin
* refactor: enhance dependency checks and embedder config in mem0 backend
* refactor: adjust fact storage message for OSS mode
* refactor: expand user paths, add collection recreation on dimension change for Qdrant
* fix(mem0): make MEM0_USER_ID override gateway-native ids and tag writes with channel
When MEM0_USER_ID was configured (env or mem0.json), the gateway-native id
from kwargs (Telegram numeric id, Discord snowflake, ...) still won, so the
same human ended up under different user_ids per channel and memories never
merged across CLI / Telegram / Slack / Discord. Mirrors openclaw's cfg.userId
pattern: configured override wins, gateway-native id is the fallback.
The legacy "hermes-user" placeholder default written by the setup wizard is
treated as unset to avoid silently bucketing every gateway user together.
Also tag every write with metadata.channel (cli/telegram/discord/...) so the
dashboard can offer per-channel filtered views without coupling identity to
the channel; document the read/write filter asymmetry as intentional
(reads scope to user_id only for cross-agent recall).

* refactor: improve Mem0 memory provider backend, pagination, config, and error handling
* refactor: update mem0 telemetry code, docs, and bump version
* fix(mem0): make get_config_schema() return unified schema with mode-aware required flag
Schema always includes api_key field so picker shows "API key / local" for
both modes. In OSS mode api_key.required=False so status won't mislead.

* refactor: improve mem0 telemetry, add env var key and OSS mode detection
* chore: bump mem0ai lower bound to 2.0.4 (latest SDK release)
* refactor: set telemetry sample rate to 1.0 and update docs for opt‑out
* fix(mem0): resolve 15 correctness, thread-safety, and resource bugs
Thread safety:
- Protect circuit breaker counters with _breaker_lock (race between
prefetch/sync daemon threads and main thread)
- Wrap sync_turn thread creation in _sync_lock; skip if previous sync
is still alive after 5 s join to prevent duplicate memory ingestion
- Guard _schedule_flush timer creation under _queue_lock (TOCTOU race)
- Capture local `backend` reference in prefetch/sync closures so
shutdown() nulling self._backend cannot crash in-flight threads
Correctness:
- Fix bool("false")==True for rerank param; parse string values explicitly
- Guard page/top_k with max(1,...) and move int() inside try blocks
- Fix fact_count=0 always in OSS mode (Memory.add returns list, not dict)
- Fix prefetch() not clearing result when thread still alive after timeout
- Fix atexit.register accumulating on repeated initialize() calls
Backend / setup:
- Handle Qdrant named-vector collections in _recreate_collection_if_dims_changed
(vectors is a dict; .size access raised AttributeError, swallowed silently)
- Wrap QdrantClient and psycopg2 conn/cursor in try/finally to prevent leaks
- Resolve ollama_bin at top of _ensure_ollama; use it for ollama pull
- Fix embedder key lookup when LLM provider has no env_var (e.g. ollama)
Also: remove _telemetry_enabled cache (env var check is cheap), bump
required mem0ai to >=2.0.7, minor README wording fix.
* fix(mem0): fix brittle qdrant path test + add telemetry sample-rate docs
- Replace generator-throw lambda with a proper def in
test_qdrant_path_not_writable; use tmp_path instead of a hardcoded
/nonexistent path so the test is root-safe
- Add MEM0_TELEMETRY_SAMPLE_RATE to memory-providers.md (was only
in the plugin README, not the user-guide docs)
* revert: remove MEM0_TELEMETRY_SAMPLE_RATE from user-guide docs
* refactor: remove telemetry from mem0 plugin and update documentation
* fix(mem0): set stdin=DEVNULL on setup subprocess calls
The TUI stdin guard (scripts/check_subprocess_stdin.py) requires every
subprocess call in plugin code to set stdin= so it can't inherit the
gateway's JSON-RPC stdin fd. Muzzle the docker/ollama calls in the OSS
setup wizard with stdin=subprocess.DEVNULL (none need interactive input).
Also covers the docker-inspect call the linter's regex misses.

Addresses reviewer feedback on #13377:
1. Restore all stripped docstrings (_load_config, _is_breaker_open,
sync_turn, register, _get_client, _read_filters, _write_filters,
_unwrap_results, save_config) and section dividers
2. Revert api_key to required:true in schema — self-hosted Mem0 also
requires auth by default; validation in _get_client() handles the
either/or logic separately from the schema
3. Confirm secret:true remains on api_key (already correct)
The mem0 plugin previously hardcoded api.mem0.ai as the endpoint.
This adds a `host` config key and MEM0_HOST env var so users can
point the plugin at a self-hosted Mem0 instance.
Changes:
- _load_config(): read MEM0_HOST env var
- is_available(): accept host OR api_key (self-hosted may not need a real key)
- get_config_schema(): add host field
- initialize(): read host from config
- _get_client(): pass host kwarg to MemoryClient when set
- system_prompt_block(): show target (cloud vs URL)
- README: document self-hosted setup
Self-hosted Honcho setup had four sharp edges:
- local/cloud URLs ending in /vN double-prefixed by the SDK (/v3/v3/... 404)
- authenticated local servers had no setup prompt for a JWT/bearer token
- profile-derived host keys could be dot-containing workspace IDs Honcho rejects
- memory-provider config files with API keys written world-readable per umask
This keeps existing behavior but makes those paths safer:
- strip a trailing /vN version segment from any configured baseUrl before SDK
init (the SDK's route builders always prepend their own version prefix);
auth-skipping stays loopback-only
- add an optional local JWT/bearer prompt in honcho setup, stored under
hosts.<host>.apiKey
- derive new profile host keys with underscores, still reading legacy
hermes.<profile> blocks
- write memory-provider config files atomically with 0600 via a shared
utils.atomic_json_write(mode=) arg (honcho/hindsight/mem0/supermemory)
- skip honcho.json parsing in gateway cache-busting unless Honcho is the active
memory provider; memoize by honcho.json mtime when active
- bust the gateway agent cache on memory.provider change
- add a hermes memory setup <provider> one-liner so fresh installs can configure
a named provider without the picker (the per-provider hermes <provider>
subcommand only registers once that provider is active)

Memory plugins (Mem0, Honcho) used static identifiers ('hermes-user',
config peerName) meaning all gateway users shared the same memory bucket.
Changes:
- AIAgent.__init__: add user_id parameter, store as self._user_id
- run_agent.py: include user_id in _init_kwargs passed to memory providers
- gateway/run.py: pass source.user_id to AIAgent in primary + background paths
- Mem0 plugin: prefer kwargs user_id over config default
- Honcho plugin: override cfg.peer_name with gateway user_id when present
CLI sessions (user_id=None) preserve existing defaults. Only gateway
sessions with a real platform user_id get per-user memory scoping.
Reported by plev333.
Comprehensive cleanup across 80 files based on automated (ruff, pyflakes, vulture)
and manual analysis of the entire codebase.
Changes by category:
Unused imports removed (~95 across 55 files):
- Removed genuinely unused imports from all major subsystems
- agent/, hermes_cli/, tools/, gateway/, plugins/, cron/
- Includes imports in try/except blocks that were truly unused
(vs availability checks which were left alone)
Unused variables removed (~25):
- Removed dead variables: connected, inner, channels, last_exc,
source, new_server_names, verify, pconfig, default_terminal,
result, pending_handled, temperature, loop
- Dropped unused argparse subparser assignments in hermes_cli/main.py
(12 instances of add_parser() where result was never used)
Dead code removed:
- run_agent.py: Removed dead ternary (None if False else None) and
surrounding unreachable branch in identity fallback
- run_agent.py: Removed write-only attribute _last_reported_tool
- hermes_cli/providers.py: Removed dead @property decorator on
module-level function (decorator has no effect outside a class)
- gateway/run.py: Removed unused MCP config load before reconnect
- gateway/platforms/slack.py: Removed dead SessionSource construction
Undefined name bugs fixed (would cause NameError at runtime):
- batch_runner.py: Added missing logger = logging.getLogger(__name__)
- tools/environments/daytona.py: Added missing Dict and Path imports
Unnecessary global statements removed (14):
- tools/terminal_tool.py: 5 functions declared global for dicts
they only mutated via .pop()/[key]=value (no rebinding)
- tools/browser_tool.py: cleanup thread loop only reads flag
- tools/rl_training_tool.py: 4 functions only do dict mutations
- tools/mcp_oauth.py: only reads the global
- hermes_time.py: only reads cached values
Inefficient patterns fixed:
- startswith/endswith tuple form: 15 instances of
x.startswith('a') or x.startswith('b') consolidated to
x.startswith(('a', 'b'))
- len(x)==0 / len(x)>0: 13 instances replaced with pythonic
truthiness checks (not x / bool(x))
- in dict.keys(): 5 instances simplified to in dict
- Redefined unused name: removed duplicate _strip_mdv2 import in
send_message_tool.py
Other fixes:
- hermes_cli/doctor.py: Replaced undefined logger.debug() with pass
- hermes_cli/config.py: Consolidated chained .endswith() calls
Test results: 3934 passed, 17 failed (all pre-existing on main),
19 skipped. Zero regressions.
Consolidated salvage from PRs #5301 (qaqcvc), #5339 (lance0),
#5058 and #5098 (maymuneth).
Mem0 API v2 compatibility (#5301):
- All reads use filters={user_id: ...} instead of bare user_id= kwarg
- All writes use filters with user_id + agent_id for attribution
- Response unwrapping for v2 dict format {results: [...]}
- Split _read_filters() vs _write_filters() — reads are user-scoped
only for cross-session recall, writes include agent_id
- Preserved 'hermes-user' default (no breaking change for existing users)
- Omitted run_id scoping from #5301 — cross-session memory is Mem0's
core value, session-scoping reads would defeat that purpose
Memory prefetch context fencing (#5339):
- Wraps prefetched memory in <memory-context> fenced blocks with system
note marking content as recalled context, NOT user input
- Sanitizes provider output to strip fence-escape sequences, preventing
injection where memory content breaks out of the fence
- API-call-time only — never persisted to session history
Secret redaction (#5058, #5098):
- Added prefix patterns for Groq (gsk_), Matrix (syt_), RetainDB
(retaindb_), Hindsight (hsk-), Mem0 (mem0_), ByteRover (brv_)
