Codex + Opus both independently caught a CORE gap in the first cut: the
bounded /api/models rebuild runs on a detached 'models-catalog-rebuild' daemon
thread that inherits neither the request-profile thread-local (#798) nor
os.environ. So on a non-default profile the worker probed the DEFAULT profile's
credentials and, when the 4s budget was exceeded, published the rebuilt catalog
to the DEFAULT profile's disk cache (cross-contamination) — exactly the slow
path a non-default cold rebuild takes.
Fix:
- profile_scope_for_detached_worker(profile_name): sets the request-profile TLS
AND applies the profile .env on the worker thread, restoring both on exit
(no-op for default). Distinct from profile_env_for_active_request (which reads
the current thread's TLS and must not clear it).
- get_available_models() captures the active profile on the request thread and
wraps the rebuild worker body (probe + over-budget publish + disk save +
fingerprint) in that scope; the legacy synchronous rebuild applies the profile
env on the foreground. /api/models route no longer wraps (the work moved into
get_available_models so ALL callers — chat/start, resolution — are fixed).
- 2 new regression tests incl. the worker-thread before/inside/after assertion.
Empirically verified: a fresh worker thread resolved models_cache.json/default
WITHOUT the scope (the bug) and models_cache.work.json + the work .env + the
work auth.json WITH it.

On a non-default profile, Settings → Providers timed out and the model
picker showed only the default profile's models. WebUI profile switching is
per-client/cookie-scoped (#798), but two read-only paths resolved from the
process-global default profile:
- Facet A: /api/providers + /api/models did not apply the active profile's
.env around the read, so get_auth_status() / provider_model_ids() / custom
key lookups resolved the default profile's credentials. On a non-default
profile the auth probes could stall past the 30s frontend abort.
- Facet B: the /api/models disk cache was a single import-time
STATE_DIR/models_cache.json shared across every profile, while the cache
fingerprint is profile-specific -> a non-default profile rejected the shared
snapshot every read and cold-rebuilt (the slow serial-probe path).
Fix:
- api.profiles.profile_env_for_active_request(): applies the active
per-request profile's .env for the duration of the read (delegates to the
existing profile_env_for_background_worker used by streaming). No-op for the
default/root profile, so single-profile deployments are byte-identical.
- api.config._get_models_cache_path(): profile-keys the disk cache filename
(models_cache.<profile>.json) derived from the default path; default profile
keeps models_cache.json unchanged (no file migration).
- routes.py: wrap both GET handlers in profile_env_for_active_request.
- conftest: restore api.profiles._active_profile + clear request-profile TLS
after each test (a pre-existing isolation hole that profile-keyed cache
paths newly surface under sharding).
Tested: 10 new regression tests; live before/after on isolated servers shows
a non-default profile now surfaces its configured provider (deepseek) with
its own credentials + its own cache file, where master showed only the
default profile's providers and one shared cache.

list_profiles_api() builds rows from cheap upstream helpers and skips find_alias_for_profile (which reads ~2.4GB of binaries from ~/.local/bin per dropdown open), with a 4s TTL cache + graceful fallback. 4700ms->250ms cold, 0ms cached. Full suite 8183 passed, Codex SAFE, Opus SHIP-IT. Supersedes #3772.
## Release v0.51.266 — Release IH (stage-r16)
One agent-authored APPROVED fix + two un-held streaming/SSE fixes.
### Fixed
| Issue/PR | Author | Fix |
|----------|--------|-----|
| #3635 (#3637) | @nesquena-hermes (nesquena APPROVED) | Composer profile chip reads `S.activeProfile` again — a #3331 regression keyed it on the loaded session's profile, so opening a cross-profile session made the chip disagree with the dropdown checkmark and misrepresent where the next message routes. #3331's project/session-op scoping is unaffected. |
| #3587 (#3605) | @rodboev | Reasoning persists to the correct intermediate assistant message in multi-turn tool flows. The index only advanced in `on_interim_assistant` (suppressed for contentless tool-call messages) → post-tool reasoning was mis-attributed; it now also advances at the `on_tool` boundary, guarded against over-increment. **(un-held — finding resolved)** |
| #2660 (#3558) | @franksong2702 | Session-event SSE no longer wakes every tab across profiles and never drops a relevant refresh — profile attached when known, root/`default` aliases stay unscoped, and the `maxsize=1` queue falls back to unscoped refresh-all on a profile-mismatch coalesce. **(un-held — both findings resolved)** |
### Gate
- Full pytest suite: **7770 passed, 0 failed**
- ESLint: CLEAN · ruff: CLEAN · browser-smoke: CLEAN
- Codex (regression): **SAFE TO SHIP** — chip matches dropdown/routing (no #3331 scoping regression), reasoning-index advance composes with the agent's tool/interim callback ordering, session-events coalesce safely with no dropped refresh and no profile data leak (`/api/sessions` still server-side filtered).

Both pre-release reviewers (Opus advisor + Codex regression gate) converged on
the same MUST-FIX:
- #3194: treating gateway_stale_stopped_state as 'configured' contradicted
#1944 (a stopped root gateway should read like 'not configured' so the
banner doesn't nag). Now ONLY stale-RUNNING metadata
(reason=gateway_stale_running_state or gateway_state=='running') flips
configured=True; stale-stopped falls through to bool(identity_map) like the
genuinely-unconfigured case. Updated the test accordingly + added a
stale-stopped no-regression test.
Opus follow-ups also applied:
- #2905: narrowed the populated-home markers to WebUI-only artifacts
(webui/, webui/sessions, webui/settings.json), dropping config.yaml/auth.json
so a long-time agent user installing WebUI fresh isn't wrongly diverted to
the legacy %USERPROFILE%\.hermes (auth.json predates #2897 there).
- profiles._resolve_base_hermes_home(): narrowed except Exception -> ImportError
so a real bug in the config helper still surfaces.
Adjacent suites green: #2840, #1879, gateway_status_agent_health (66 tests).
Two urgent breaking bugs that had no PR, combined into one hotfix.
#2905 (data-loss-class): v0.51.134 moved the Windows default Hermes home
from %USERPROFILE%\.hermes to %LOCALAPPDATA%\hermes (PR #2897) with no
migration, so upgrading Windows users opened the app to empty
sessions/pins/settings (data intact on disk, at an address the new build
no longer read). _platform_default_hermes_home() now prefers the populated
legacy home ONLY when the new location is not yet established —
non-destructive (no file moves) and self-healing on next launch.
profiles._resolve_base_hermes_home() delegates to the same config helper so
the active-profile pointer can never drift from STATE_DIR.
#3194: GET /api/gateway/status reported 'Gateway not configured' on a fresh
two-container Docker deploy because an alive=None + gateway_stale_running_state
health payload with an empty identity_map fell through to
configured=bool(identity_map)=False. The alive=None branch now treats a
payload carrying gateway metadata (gateway_state detail, or a stale-running/
stale-stopped reason) as configured.
Tests: +17 regression tests (11 for #2905 incl. full truth table + non-destructive
guard + POSIX no-op; 6 for #3194 incl. 5 no-regression guards). Full suite
7090 passed, 0 failed.
Closes#2905Closes#3194
When a user creates a profile through the WebUI and supplies an API key,
the key was written to config.yaml under model.api_key. However, Hermes
Agent's provider layer reads keys from environment variables (.env), not
from config.yaml — making the key invisible to the actual LLM provider.
Additionally, hermes profile show reports .env: not configured when no
.env file exists, regardless of config.yaml contents, giving users the
false impression that their API key was not saved.
Changes:
- Add _PROVIDER_ENV_MAP to resolve provider IDs to .env variable names
(kimi-coding → KIMI_API_KEY, deepseek → DEEPSEEK_API_KEY, etc.)
- Add _write_api_key_to_dotenv() that writes the key to the profile's
.env file under the correct provider-specific variable
- Add _upsert_dotenv_line() helper for idempotent KEY=value writes
- Remove api_key writing from _write_endpoint_to_config()
- Wire _write_api_key_to_dotenv() into create_profile_api()
Fixes: profile created via WebUI shows .env: not configured despite
correct API key being entered in the form.
#2299 introduced profile_env_for_background_worker() in api/profiles.py and
changed _ENV_LOCK from threading.Lock() to threading.RLock(). Both changes
were incorrect:
1. RLock masked rather than fixed the underlying deadlock. The QA
test_env_lock_is_non_reentrant test exists precisely to enforce
non-reentrance — RLock would let a single thread hold _ENV_LOCK across
nested critical sections, which hides bugs while still allowing
different-thread races.
2. The original context manager held _ENV_LOCK for the ENTIRE 'yield'
duration, meaning the lock was held for the full background worker's
runtime (title generation, compression, update summary — possibly
many seconds). That blocked ALL other sessions on _ENV_LOCK, which
the QA test_third_message_completes runtime test caught as a timeout
on the third sequential message.
Fix: mirror the narrow-lock pattern from _run_agent_streaming:
- Acquire _ENV_LOCK only for env mutation (set runtime_env + patch
skill modules)
- Release immediately, yield to worker (no lock held)
- Reacquire in finally to restore env + skill modules
Restored _ENV_LOCK back to threading.Lock(). All 20 QA tests now pass,
including test_third_message_completes (was timing out, now 35s).
Maintainer review on PR #1895 flagged that mcp_server.py duplicated the
visibility model from api/routes.py:75. Move the canonical helper into
api/profiles.py (next to _is_root_profile, on which it depends) so both
api/routes.py and mcp_server.py import the same function instead of
carrying parallel definitions that could drift as the model evolves.
- api/profiles.py: + _profiles_match (verbatim from former routes.py:75-97)
- api/routes.py: replace local definition with re-export to keep all
existing _profiles_match(...) call sites resolving
without per-call-site refactors
- mcp_server.py: drop local copy, import _profiles_match alongside the
existing api.profiles imports (line 59)
- tests: + test_profiles_match_single_source_of_truth asserts
identity (mcp.module._profiles_match is api.profiles._profiles_match
is api.routes._profiles_match) so any re-introduction of
a local copy trips the test
+ test_profiles_match_input_matrix parametrize across
the (None|''|'default'|'foo') x (None|''|'default'|'foo'|'bar')
visibility matrix per maintainer suggestion
Behaviour unchanged. Zero call-site changes anywhere in api/routes.py.

SHOULD-FIX #1 (renamed-root client cross-alias): drop strict-equality client
filter at static/sessions.js:1853. Server-side _profiles_match cross-aliases
'default'-tagged rows to a renamed root 'kinni'; the strict-equality client
would reject them, dropping every legacy session for renamed-root users. The
server is now solely authoritative for profile scoping.
SHOULD-FIX #2 (messaging-source dedupe ordering): _keep_latest_messaging_session_per_source
now runs AFTER the profile filter at api/routes.py:2078. Before, it ran on
the merged-cross-profile list with profile-blind keys, discarding the older
profile's row across profiles before the scope filter — leaving zero rows for
any messaging identity the active profile shared with another profile.
NIT #3: _projects_migrated flag now set only AFTER successful save_projects.
NIT #4: cleaned dead test code in test_is_root_profile_invalidation_drops_stale.
NIT #5: _create_profile_fallback's clone_from=='default' literal now routes
through _is_root_profile() for parity with the 5 other callsites.
+2 regression tests pin the SHOULD-FIX shapes:
- test_keep_latest_messaging_runs_after_profile_filter (source-string ordering)
- test_static_sessions_js_trusts_server_profile_scoping (no client re-filter)
4173 -> 4175 tests pass. 0 regressions.
Closes#1611 — /api/sessions filters by active profile by default; ?all_profiles=1
opt-in for aggregate views; new _profiles_match() helper honours renamed-root
cross-aliasing; static/sessions.js drops the s.is_cli_session bypass; toggle-on
re-fetches with all_profiles=1 instead of slicing client-cached rows.
Closes#1612 — new _is_root_profile() central helper consults list_profiles_api()
for is_default=True matches alongside the legacy 'default' alias. Replaces five
literal-default callsites in api/profiles.py. Memoized with explicit invalidation
hooks at create + delete. Sticky active_profile file write now stores '' for
renamed root, consistent with the legacy empty==root contract.
Closes#1614 — projects carry a profile field stamped at create-time;
/api/projects filters by active profile; /api/projects/{create,rename,delete}
and /api/session/move reject ops on cross-profile projects with 404; new
_PROJECTS_MIGRATION migration in load_projects() back-tags untagged projects
from any session that uses them, fall back to 'default'; ensure_cron_project
keys lookup by (name, profile) so each profile gets its own Cron Jobs project.
31 regression tests (9+11+11) pin the renamed-root resolution, server-side
profile scoping shape, helper invariants, cross-alias matching, migration
behavior, and active-profile guards on every project mutation endpoint.
4148 tests pass.

Three small follow-ups from the review:
1. Remove the over-broad except Exception around get_active_hermes_home()
in _handle_cron_run. The function is in-memory dict reads + one
Path.is_dir() stat — if it raises from inside a request handler,
api.profiles is in a state we shouldn't be making cron decisions in.
A silent fallback to _profile_home=None re-introduces the exact
bug #1573 fixes (worker thread runs unpinned against process-global
HERMES_HOME). Better to 500 the request than risk silent cross-
profile state corruption.
2. Add a thread-safety note on os.environ mutation in api/profiles.py
explaining why _cron_env_lock is sufficient — CPython env-var
assignment is GIL-protected at the bytecode level but the multi-step
read-modify-write pattern (snapshot prev → assign new → restore on
exit) is not atomic without explicit serialization. The lock makes
the entire context-manager body run-to-completion serially, including
any subprocess.Popen() calls inside run_job() that inherit the env.
3. New regression test (test_cron_run_does_not_silently_swallow_profile_resolution_errors)
pinning the no-silent-fallback contract via source-level assertion.
Catches future re-introduction of the over-broad except clause.

Wrap all /api/crons* endpoints in cron_profile_context so the TLS-active
profile's jobs.json is read/written, not the process-default one.
Before: cron.jobs._get_jobs_file() reads HERMES_HOME from os.environ
(process-global) at call time, bypassing WebUI's per-request thread-local
profile. Result: the Scheduled jobs panel always showed the default
profile's jobs regardless of which profile the user selected via cookie,
and CRUD operations silently wrote to the wrong jobs.json.
Fix:
- api/profiles.py: new cron_profile_context (HTTP/TLS) and
cron_profile_context_for_home (worker threads) context managers. Both
hold a module-level lock, swap os.environ['HERMES_HOME'], and re-patch
cron.jobs module-level constants (HERMES_DIR/CRON_DIR/JOBS_FILE/
OUTPUT_DIR are import-time snapshots that don't participate in the
module's lazy __getattr__ path).
- api/routes.py: wrap all 12 cron endpoints (GET + POST). For
/api/crons/run, capture the TLS-active home at dispatch time and
pass it into the background thread so cron output lands in the right
profile directory.
Tests: 3 new regression tests in test_scheduled_jobs_profile_isolation.py
cover TLS-based pinning, explicit-home pinning, and serialization of
concurrent contexts. Full cron + profile test suite (24 tests) passes.

Opus pass-2 review of v0.50.251 caught a critical regression in PR
#1375:
The cancel-partial message stored captured tool calls under the
'tool_calls' key. That key is whitelisted by _API_SAFE_MSG_KEYS so
_sanitize_messages_for_api forwarded the entries to the next-turn
LLM call. But the captured entries use the WebUI internal shape
({name, args, done, duration, is_error}) — they don't have the
OpenAI/Anthropic id + function: {name, arguments} envelope. Strict
providers (OpenAI, Anthropic, Z.AI/GLM) would 400 on the malformed
entries. Net effect: the very cancel-then-continue scenario PR
#1375 aimed to improve becomes a hard fail.
Fix:
- Rename the persisted key to '_partial_tool_calls' (underscore-
prefixed private key NOT in _API_SAFE_MSG_KEYS, so sanitize
correctly strips it).
- Update static/messages.js hasMessageToolMetadata check to also
recognize _partial_tool_calls for UI rendering.
- Update test_issue1361_cancel_data_loss.py assertion to check
_partial_tool_calls (and tool_calls as legacy fallback).
Plus 2 NIT fixes from the same Opus review:
NIT 1 (api/profiles.py:153): re.match → re.fullmatch for consistency
with other _PROFILE_ID_RE callers in the codebase. The trailing-
newline footgun ($ matches before final \n in re.match) is now
closed. Without #1373's is_dir() guard, a name like 'valid\n' would
have created a directory named 'valid\n' on Linux. Doesn't escape
<HERMES_HOME>/profiles/ via Path joining, but unintended.
NIT 2 (test_issue798.py): R19j coverage gaps — added trailing-
newline tests, length-boundary tests (64-char valid, 65-char
rejected), single-char minimum, and non-ASCII / Unicode-trick tests.
New regression test (tests/test_pr1375_partial_tool_calls_sanitize.py):
- test_partial_tool_calls_field_not_forwarded_to_llm: pins that
sanitize-for-API strips _partial_tool_calls + reasoning + does
NOT have tool_calls on a partial message
- test_legitimate_tool_calls_are_preserved_for_completed_turns:
pins that real OpenAI-shape tool_calls on completed turns survive
sanitize unchanged
Tests: 3486 passing (3484 → 3486, +2 sanitize tests).
When a user switched profiles and created a new session, the session
was saved to the default profile directory instead of the active
profile directory — because get_hermes_home_for_profile() silently
fell back to _DEFAULT_HERMES_HOME when the profile directory didn't
exist yet on disk.
Root cause: api/profiles.py:156 had `if profile_dir.is_dir(): return
profile_dir; return _DEFAULT_HERMES_HOME`. New profiles (no session
yet, so no dir) routed every session back to default.
Fix: remove the is_dir() guard, return the profile path
unconditionally. The profile directory is created on first use by
the agent/session layer.
5 regression tests in tests/test_issue1195_session_profile_routing.py:
existing-profile, non-existent-profile (the core fix), None, empty-
string, 'default' all return the expected path.

Fixes the multi-client profile isolation bug (#798).
- get_hermes_home_for_profile(): pure path resolver, validates name against
_PROFILE_ID_RE (rejects path traversal), never mutates os.environ or globals
- new_session() accepts explicit profile= param from POST body (S.activeProfile),
short-circuits the process-level _active_profile global
- streaming handler resolves HERMES_HOME from s.profile instead of the global
- sessions.js sends profile: S.activeProfile in every new-session POST
10 tests in tests/test_issue798.py including concurrency and traversal coverage.

* fix(profiles): block path traversal in profile switch and delete flows (#399)
Master was vulnerable: switch_profile and delete_profile_api joined user-supplied profile
names directly into filesystem paths with no validation. An attacker could send
'../../etc/passwd' as a profile name to traverse outside the profiles directory.
- api/profiles.py: add _resolve_named_profile_home(name) — validates name with
^[a-z0-9][a-z0-9_-]{0,63}$ regex then enforces path containment via
candidate.resolve().relative_to(profiles_root); use in switch_profile()
- api/profiles.py: add _validate_profile_name() call to delete_profile_api() entry
- api/routes.py: add _validate_profile_name() call at HTTP handler level for
both /api/profile/switch and /api/profile/delete (fail-fast at API boundary)
- tests/test_profile_path_security.py: 3 tests — traversal rejected, valid name passes
Cherry-picked commit aae7a30 from @Hinotoi-agent (PR was 62 commits behind master)
* feat: add desktop microphone transcription fallback (#396)
Mic button now works in browsers that support getUserMedia/MediaRecorder but
lack SpeechRecognition (e.g. Firefox desktop, some Chromium builds).
- static/boot.js: detect _canRecordAudio (navigator.mediaDevices + getUserMedia + MediaRecorder);
keep mic button enabled when either SpeechRecognition or MediaRecorder is available;
MediaRecorder fallback records audio, sends blob to /api/transcribe, inserts transcript
into the composer; _stopMic() handles all three states (recognition, mediaRecorder, neither)
- api/upload.py: add transcribe_audio() helper — saves uploaded blob to temp file, calls
transcription_tools.transcribe_audio(), always cleans up temp file
- api/routes.py: add /api/transcribe POST handler — CSRF protected, auth-gated, 20MB limit,
returns {text:...} or {error:...}
- api/helpers.py: change Permissions-Policy microphone=() to microphone=(self) (required to
allow getUserMedia in the same origin)
- tests/test_voice_transcribe_endpoint.py: 87 new lines — 3 tests with mocked transcription
- tests/test_sprint19.py: +1 regression guard (microphone=(self) in Permissions-Policy)
- tests/test_sprint20.py: 3 updated tests for new fallback-capability checks
