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.
plugins/platforms/a2a/security.py::redact_outbound shipped text to a REMOTE peer
through 8 private regexes (sk-, sk-ant-, ghp_ only, xox[bap] only, AKIA, JWT,
Bearer, email) and never called redact_sensitive_text, so every prefix added to
agent/redact.py (hf_, glpat-, xapp-, npm_, Telegram bot tokens, private keys,
DB URLs, env assignments, auth headers, plugin-registered patterns) was absent
on the A2A path. gateway/run.py::_GATEWAY_SECRET_PATTERNS and
agent/monitoring/redaction.py::_TOKEN_RE/_BEARER_RE were two more parallel
"fallback" lists to maintain.
Now agent/redact.py::redact_for_egress is the one egress scrub:
redact_sensitive_text(force=True) + a bearer sweep for prefix-less opaque
tokens, fail-closed ("[redaction-unavailable]"). Gateway user-facing text,
monitoring export and A2A outbound call it; A2A keeps only its e-mail pass.
Behavior changes: a2a egress now masks the full canonical set; the gateway
chat path returns the fail-closed sentinel instead of a raw string when the
redactor raises; honcho plugin registers hch-at-/hch-rt- with
register_redaction_patterns (masked on every surface; mask shape is the
shared head/tail form instead of "hch-at-[redacted]"); proxy_cli token
display uses mask_secret (4 visible prefix chars instead of 12).
Invariant test: redact_outbound masks a synthesized token for every
registered prefix pattern (fails when reverted to the private list).
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.
ThreadingHTTPServer request threads do not inherit the gateway's profile
ContextVars, so security.authenticate()/is_trusted_peer() read the
process-global A2A_* env on every request — every secondary profile's
listener authenticated against the default profile's tokens. Capture an
immutable A2ASecurityContext at adapter construction (which runs inside
_profile_runtime_scope for secondary profiles) and have the request
handler consult it instead of re-reading env per request.
Salvage note: the original `get_secret() / except UnscopedSecretError:
os.getenv()` fallthrough in _startup_env was replaced by _profile_scoped()
gating (Buzz/Raft pattern) — inside a secondary profile's scope the scope
is authoritative and a miss never falls through to os.environ.
Salvaged from #80956.
Consolidates 5 follow-up PRs onto the a2a-work branch:
1. Reply-capture fix (#56437): adapter.send() now only resolves the
blocked RPC Future when metadata['notify'] is True (the gateway's
final-reply marker). Interim sends no longer short-circuit the
response. Also accepts **kwargs in connect() for reconnect compat.
2. Slash command passthrough (#53743): wrap_inbound() passes /-prefixed
text through unwrapped so the gateway command processor sees it.
Fixes /sethome deadlock during A2A onboarding. Documented security
trade-off (bearer auth at network layer compensates).
3. Routable URL in Agent Card (#53736): _build_card() now derives URL
from A2A_PUBLIC_URL env > X-Forwarded-Host/Host header > bind host.
Fixes k8s bug where Agent Card advertised 0.0.0.0.
4. contextId multi-turn memory (#53756): _handle_inbound_task() now
checks top-level params.contextId first (A2A spec), falls back to
params.message.contextId (legacy). Outbound a2a_call also sends
contextId at both top-level and inside message.
5. Type checker fixes (#53759): TypedDict for _SCHEMAS, _FunctionSchema,
_ToolSchema. Removes str() band-aid casts.
All 45 tests pass including new tests for each fix.

Single platform-adapter plugin under plugins/platforms/a2a/ — zero core
edits — that supersedes the entire A2A PR/issue cluster. Built on the
ctx.register_platform + ctx.register_tool surface the codebase now exposes.
Outbound (a2a toolset): a2a_discover / a2a_call / a2a_list let the agent
call any A2A-compliant peer over JSON-RPC message/send. Inbound (platform
adapter): a stdlib http.server serves an Agent Card at
/.well-known/agent.json and routes incoming tasks into the agent's LIVE
gateway session (the #11025 insight) — same agent, full memory — returning
the reply over A2A.
Security on by default: no bearer token => 127.0.0.1-only bind; constant-
time bearer auth; inbound prompt-injection filtering + untrusted-peer
framing; outbound credential redaction; append-only audit log; per-context
conversation persistence outside the compaction pipeline.
Stdlib only (no a2a-sdk). 37 tests incl. a live HTTP round-trip
(card + message/send + reply) and a bearer-auth 401 path.
