webtecnica 02b5f885c8 fix(share): harden _embed_share_media with path allow-list + mime validation (#6174)
Embed local MEDIA: image refs as inline base64 at snapshot-build time,
gated by a workspace/attachment-root allow-list, 512KiB cap, image-MIME
allow-list, and magic-byte content validation. Everything else (traversal,
symlink-escape, file://, non-image, SVG, oversize) becomes a static
placeholder. Closes P0 #6174 (public shares no longer emit authenticated
/api/media requests for local paths).

* fix: resolve provider alias before matching _PROVIDER_MODELS (#6148)

* fix(backend): resolve model prefix through _PROVIDER_ALIASES before matching

- Fix IndentationError: dedent _canon_prefix assignment to 8 spaces
- Rebased onto upstream/master
- Add regression test: alias prefix (z-ai) resolves to canonical key (zai)
  and routes cross-provider through OpenRouter (#6131)

* fix(#6131): canonicalize both sides via _canonicalise_provider_id (idempotent) + regression tests

Codex found _resolve_provider_alias breaks Qwen (qwen->alibaba, not in _PROVIDER_MODELS)
and cross-routes alias-of-active-provider (raw vs canon asymmetry). Use the idempotent
_canonicalise_provider_id for both membership and equality. Adds 2 regression tests.

* docs(changelog): stamp #6148 alias-prefix model routing fix

8586572da5 Release: #6389 stream-teardown leak fix (exp-v0.52.139) (#6416)
* fix(#6389): remove clear_offline_buffer() teardown blocks that cause data loss on late reconnects

Keep the real leak fixes:
- unregister_stream_owner() in both streaming.py and gateway_chat.py
- AGENT_INSTANCES.pop() in gateway_chat.py

The clear_offline_buffer() calls could clear a channel's offline buffer
after a late reconnect already fetched the channel but before it subscribed,
causing the reconnecting client to lose all buffered events (including
stream_end) and hang indefinitely on heartbeats.

STREAMS.pop() already releases registry ownership; GC reclaims the buffer
once the last outstanding channel reference is dropped, correctly preserving
replay for in-flight reconnects.

webtecnica 700bd976c1 fix(media): narrow MIME_MAP to only .ts/.tsx text/plain, add regression tests
- Add only .ts→text/plain and .tsx→text/plain to MIME_MAP (exclude .js,
  .jsx, .css and other unsafe mappings that would make workspace files
  executable as same-origin scripts)
- Add test_ts_artifact_served_as_text_plain_with_attachment — asserts
  Content-Type: text/plain, Content-Disposition: attachment, and
  X-Content-Type-Options: nosniff for .ts files via /api/media
- Add test_tsx_artifact_served_as_text_plain_with_attachment — same for .tsx
- Add test_file_raw_js_not_served_as_inline_executable — proves that a
  workspace .js file falls through to application/octet-stream instead of
  text/javascript via /api/file/raw

Closes #6372

nesquena-hermes 5ff16c59d4 fix(streaming): catch OverflowError in _terminal_turn_duration so a huge/invalid pending_started_at can't abort terminal-error settlement
Codex gate on #6312 found the extracted helper caught only (TypeError, ValueError)
while the inline code it replaced caught Exception; float(10**400) raises
OverflowError, escaping the helper and aborting terminal-error cleanup before the
error message is persisted / apperror is emitted. Widen _terminal_turn_duration's
float() guard to (TypeError, ValueError, OverflowError) — the exact exceptions
float() can raise. Adds 10**400 to the existing invalid-origin parametrize
(red-before-green verified).

b3nw 9bf876598d fix: stamp post-run agent.model + one model label per turn (#6068 gate)
Addresses the three gate-review blockers on #6113:

- Fallback attribution: read the served model from agent.model AFTER the
  run (the agent mutates it when a fallback fires) instead of the pre-run
  resolved_model, for both the persisted _usedModel and SSE used_model.
- Gateway double-label: suppress the additive chip whenever
  _gatewayRouting is present, and pass msg._usedModel to
  _formatGatewayModelLabel as its model fallback when routing omits
  used_model.
- Transparent double-label: skip the generic .msg-used-model-inline chip
  when the transparent turn footer owns the model label (.lf-model).

Also per Greptile: settled footer now orders the model chip after the
duration (elapsed - model - ...) to match the transparent footer, and the
test file gains its trailing newline.

b3nw 30aef85b18 feat: stamp per-turn used model in footer stats (#6068)

in the usage SSE payload, and render model chips in transparent and settled
turn footers while suppressing duplicates when gateway routing already shows
used_model.

c414c39f10 feat(extensions): token-v1 proxy→sidecar authentication boundary (#6331)
* feat(extensions): token-v1 proxy->sidecar auth boundary

Mint a per-extension secret core injects (X-Hermes-Sidecar-Token) on every
proxied request; sidecars validate it. Closes the hole where a loopback sidecar
port is reachable by any local process and cannot distinguish a proxied request
from a direct one.

- api/extension_sidecar_auth.py: per-extension token lifecycle (atomic mint,
  re-read-verified so an unpersisted token is never injected, per-request
  mtime-cached read for live rotation, path-escape-safe)
- manifest proxy_auth negotiation: absent=legacy, token-v1=enforce, unknown=fail-closed
- proxy: inject token, strip inbound + response x-hermes-*, auth-off posture
  (loopback-only local_unprotected, else 503), fail-closed when token unavailable
- consent-time auth_required in status payload; mint-on-consent
- docs/EXTENSIONS.md proxy_auth section
- 7 new tests (26/26 green)

* fix(extensions): address Codex+Fable gate on token-v1 (6 findings)

- align token-module extension-id grammar with core _EXTENSION_ID_RE (was
  narrower -> legally-named ext consented then 503'd forever)
- resolve token dir dynamically (mirror _extension_state_dir) -> real test
  isolation, no import-time STATE_DIR cache
- cross-process mint: O_CREAT|O_EXCL no-clobber claim (was os.replace clobber)
- rotation cache keyed on full fingerprint (ino/dev/mtime/ctime/size) +
  re-fingerprint after read -> same-size/mtime replacement no longer stale
- validate token format on read (url-safe, 16-256) -> malformed file can't
  leak via a ValueError echoed in a 502
- consent fails 503 when token can't be provisioned (was silent-swallow ->
  persisted consent then 503 forever)
- rename status auth_required -> posture enum (protected|local_unprotected):
  nothing is blocked for loopback, so 'required' was misleading
- panels.js: render local_unprotected warning on the consent row (+ CSS)
- docs: token-path resolution order, 401-vs-503, explicit 'legacy' acceptance
- tests: route-level token-injection+response-strip test; fix illusory isolation
  in token-module test; 27/27 green

* fix(extensions): close 2 token-mint races (Codex re-gate round 2)

- mint via temp-file + atomic os.replace (not O_CREAT|O_EXCL) so the final
  path is never observed empty/half-written — a concurrent loser can no longer
  read an empty token file and 503
- single _stable_read helper (fingerprint-read-refingerprint, bounded retry on
  mid-read change) used by BOTH ensure_token and current_token — a token that
  changes during the read is never returned or cached stale
- stress-verified: 20 concurrent first-mints converge on 1 persisted token; 27/27

* fix(extensions): atomic no-clobber token publish via os.link (Codex re-gate round 3)

os.replace fixed empty-file exposure but still clobbered cross-process: two
processes could both write+replace and a reader between them got a token no
longer on disk -> 401. Switch to the repo's TOCTOU-safe os.link create-or-fail
idiom (session_recovery.py:627): write temp -> link into place (fails if a
winner already published) -> loser drops its temp and reads the winner via
_stable_read. Proven: 16 concurrent PROCESSES converge on 1 persisted token,
all matching disk. 27/27 tests green.

* fix(extensions): resolve Frank+Greptile #6331 review — token-v1 fail-closed when auth off (consent+resolution), token-v1-only proxy_auth/posture status fields, fullmatch ext-id validator

* fix(extensions): finish Frank and Greptile sidecar review

4d9965b37a Release: content search no longer evicts the working-set cache (#6084, @ai-ag2026) (#6343)
* fix(webui): keep the content search from evicting the user's working set

/api/sessions/search?content=1 walks EVERY session and pulls each one through
get_session(), which inserts it into the SESSIONS LRU and marks it
recently-used. On any install with more sessions than sessions_cache_max
(default 300), a single search therefore flushes the whole cache and refills it
with sessions the user is not looking at — the classic buffer-pool
scan-pollution problem. The sessions actually open in the UI are exactly the
ones evicted, and the search is keystroke-debounced, so it repeats while typing.

A scan reads each session exactly once, so nothing it touches has earned
"recently used". get_session_for_scan() reuses a resident session without
promoting it, and reads a cold one straight from disk without caching it. It
returns None rather than raising, since a scan skips what it cannot open.

This is a correctness fix for cache behaviour, not a latency fix. The
multi-second searches that led here were contention, not scan cost: a trivial
/api/profiles took 9.2s in the same window, and a full read+parse of ~1700 real
sessions measures ~4s total.

test_sessions_search_depth_validation patched api.routes.get_session. With the
search reading through the scan accessor it now patches get_session_for_scan —
left unfixed, two of its cases fail and the third passes vacuously against an
empty result set.

Validation:
  pytest tests/test_issue4765_sessions_lru_eviction.py
         tests/test_sessions_search_depth_validation.py   ->  13 passed
  Both added eviction tests fail on the pre-fix accessor (verified by revert):
  the working set drops from 4/4 to 0/4 resident after one scan.

10e5c52b10 Release: broadcast terminal output to every viewer (#5836, @ai-ag2026) (#6340)
* feat(terminal): broadcast output to every viewer instead of one shared queue

TerminalSession.output was a single queue.Queue read destructively by the SSE
handler. Two tabs/windows viewing the SAME session each open their own
EventSource, so two _handle_terminal_output handlers competed on that one queue:
every PTY chunk was delivered to exactly one of them. Each tab saw a disjoint
half of the byte stream, and only one ever received terminal_closed.

Output now fans out, mirroring StreamChannel/SessionChannel: each SSE consumer
subscribe()s its own queue (seeded with a bounded backlog so a first/late attach
still replays the recent scrollback, preserving the old buffer-until-first-
consumer behaviour), and put_output broadcasts to all subscribers. A slow
viewer's queue drops its own oldest chunk (drop-oldest, isolated per subscriber)
so one lagging tab can't starve another. The handler unsubscribes in a finally
so the subscriber list can't grow.

Stacked on the terminal fd-leak fix (same file).

Complements #6283 (which covered async_delegation completions). Thanks @allenliang2022.

6ad84d7dd3 fix(wakeup): route async-delegation completions by origin + durable-claim delivery (#6283)
Route async-delegation completions by the immutable origin_ui_session_id (exact origin tab) and deliver them through a durable claim/complete/release lifecycle so they arrive exactly once, restart-safe, on both the background wakeup and next-turn drain paths. Combines #6185 (@carlotestor) + #6159 (@sysophelper-droid); supersedes #6002/#6225.

ai-ag2026andClaude Fable 5 0dc16dcce8 fix(config): restore read-only-target protection for atomic writes
Review finding 2 (10.07 gate): a deliberately locked config (0444) in a
writable directory was silently overwritten — atomic replace creates a
fresh temp inode and renames over the read-only file, defeating the old
in-place Path.write_text PermissionError contract.

Probe the existing target with a non-truncating O_WRONLY open before any
replacement work and let the PermissionError propagate. The probe fstat()s
the fd it actually opened and hands that stat to the rest of the write, so
a concurrent writer replacing the inode between stat and probe refreshes
the metadata instead of failing (keeps concurrent-writer semantics).

Regression: writable parent + 0444 target now raises and keeps the
original bytes and mode.

69ffaf3443 Release: byte-size threshold for reconnect tail optimization (#6260, @webtecnica) (#6263)
* perf: optimize large session reconnect by adding file-size threshold to tail optimization (#6241)

When a sidecar JSON file exceeds 500 KB, the display-path tail optimization
now fires even if the message count is within the raw_budget. This prevents
sessions with few messages but large tool outputs (multi-MB JSON) from
forcing a full-scan merge of all messages on reconnect.

Changes:
- Added _sidecar_file_exceeds_threshold() helper
- Added _SIDECAR_BYTE_TAIL_THRESHOLD = 500_000 constant
- Fall-through to truncation in _state_db_since_timestamp_for_limited_display
  when the sidecar file exceeds the threshold, regardless of message count

* CHANGELOG: byte-size reconnect tail optimization (#6260)

c4284529b0 Release: OIDC allowlist whitespace fix (#6244, @webtecnica) (#6259)
* fix: split OIDC allowlist on commas only, preserve scope whitespace-split (#6244)

_normalize_text_list is shared with _normalize_scopes — OAuth scopes
are space-delimited per RFC 6749 §3.3. Created _normalize_allow_values
that splits on commas/newlines only, keeping multi-word group names
like 'Hermes Users' intact.

* fix(oidc): filter blank allow_values list elements + add parser-split test (gate follow-up)

The new comma/newline-only _normalize_allow_values() list-path retained empty
strings that the shared _normalize_text_list() had filtered, so a YAML
allow_values: [""] would brick an OIDC-only deployment (every callback 403s).
Filter stripped-empty collection elements. Adds a regression test asserting
allowlist multi-word preservation, comma/newline splitting, blank filtering,
and that scopes stay space-delimited (RFC 6749 §3.3).

d195b094bb Release: GLM per-version reasoning controls (#6219, @rh-id) (#6243)
* fix(reasoning): gate reasoning_effort ladder to GLM-5.2+ on native zai

Z.AI's API (docs.z.ai) defines reasoning_effort as GLM-5.2+ exclusive, but
hemes-webui advertised the full 6-level ladder for all 7 GLM models because
_candidate_supports_reasoning has an unconditional glm token match and
_filter_reasoning_efforts_for_provider had no ZAI branch. Six of seven catalog
models (glm-5.1, glm-5, glm-5-turbo, glm-4.7, glm-4.5, glm-4.5-flash) showed a
selector whose values the endpoint silently ignores, and GLM-4.7 (forced thinking
that cannot be disabled per Z.AI docs) showed a 'none' option with no effect.

Add a ZAI branch to _filter_reasoning_efforts_for_provider mirroring the existing
OpenAI/Gemini/Anthropic ceiling pattern: strip the whole ladder for pre-5.2 GLM
models and for the forced-thinking GLM-4.7 family; preserve the full ladder for
GLM-5.2+ (whose accepted values match VALID_REASONING_EFFORTS exactly). The gate
is scoped to the native zai provider only (aliases glm/z-ai/z.ai/zhipu all
resolve to zai); aggregator providers are untouched because they route through
their own routers, not Z.AI's native endpoint.

The glm family-detection heuristic in _candidate_supports_reasoning is unchanged
— GLM models DO support the thinking on/off toggle at the family level; this fix
is specifically about the reasoning_effort intensity ladder.

State layer: agent.reasoning_effort config + UI dropdown options derived from
resolve_model_reasoning_efforts. Invariant: UI options and coercion now agree
and match Z.AI's per-model docs (max offered only for GLM-5.2+, none never
offered for forced-thinking models). Out of scope: the thinking:{type:...}
request-field translation lives in the external agent/gateway layer.

* fix(reasoning): close ZAI coercion gap + harden test assertions

Address Greptile review on #6219 (round 1):

1. Vacuous test assertion (test_glm_5_2_preserves_none_sentinel): the 'or'
   fallback made the assertion always-true, so a regression stripping 'none'
   for GLM-5.2 would go undetected. Rewrote to inject 'none' via the raw source
   (mocking _resolve_model_reasoning_efforts_impl) and assert it survives — the
   test now genuinely exercises the preservation branch.

2. Coercion gap for non-max stored levels on pre-5.2 GLM: the existing
   'if ceiling and raw not in ceiling' guard treats an empty ceiling as 'no
   rule' (preserving the configured effort verbatim per #3505), so a stored
   'high'/'medium'/'low' for glm-5.1/glm-4.5/glm-4.7 on native zai was forwarded
   to Z.AI unchanged and silently ignored — contradicting the PR's stated
   UI/coercion agreement invariant.

   Root cause: the ZAI gate returns [] to mean 'known-empty' (no
   reasoning_effort at all), but the coercion path treated all [] as
   'ambiguous/unknown, preserve verbatim'. Fixed by extracting the ZAI decision
   into _zai_glm_reasoning_efforts_supported (True/False/None sentinel) shared by
   both the filter and coercion, then special-casing the known-False result in
   coerce_reasoning_effort_for_model to return '' (send no field). The #3505
   preserve-verbatim behavior for genuinely-unknown models on non-zai providers
   is unchanged.

Added 10 regression tests (all fail before the coercion fix, pass after):
- All 6 levels (max..minimal) coerce to '' for each pre-5.2 GLM + glm-4.7
- All 4 aliases (glm/z-ai/z.ai/zhipu) resolve through the same coercion gate
- GLM-5.2 preserves all 6 levels verbatim
- Regression guard: unknown model on custom: provider STILL preserves verbatim

State layer: agent.reasoning_effort config + the value forwarded to Z.AI.
Invariant now fully holds: UI offers no options for pre-5.2 GLM AND coercion
sends no reasoning_effort field for any stored level on those models.

* fix(reasoning): preserve ZAI GLM 4.5-5.1 thinking toggle when effort ladder empty

Address nesquena-hermes round-2 review on #6219: returning [] for the effort
ladder on sub-5.2 GLM models hid the entire reasoning chip in the composer
(static/ui.js:4932 treats empty supported_efforts as 'no reasoning control at
all'), silently regressing the working thinking on/off toggle for GLM-4.5/4.6/
5.0/5.1 users. Per Z.AI's own docs, those models accept the thinking
{type:enabled|disabled} toggle even though they do not accept the
reasoning_effort intensity ladder.

Fix decouples thinking-toggle capability from the effort ladder:

Backend (api/config.py):
- Refactor _zai_glm_classification returns one of 'effort' (GLM-5.2+), 'thinking'
  (GLM-4.5 up to but not including 5.2), 'forced' (GLM-4.7 family), or None
  (non-zai / non-GLM). Single source of truth shared by all three consumers.
- _zai_glm_reasoning_efforts_supported now wraps classification for the coercion
  contract (unchanged behavior).
- _zai_glm_thinking_toggle_supported returns True for 'effort' or 'thinking',
  False for 'forced', None otherwise.
- get_reasoning_status gains a supports_thinking_toggle field = bool(supported)
  OR (zai_thinking is True). Non-zai providers default to bool(supported_efforts)
  so their chip-visibility behavior is unchanged.

Frontend (static/ui.js):
- New _currentReasoningToggleSupported state var (default undefined = treat as
  true so legacy responses without the field do not newly hide the chip).
- _applyReasoningChip shows the chip when hasEffortLadder OR toggleSupported.
  Empty efforts + toggle=True keeps the chip visible with just the None/On
  control (the existing _applyReasoningOptions already shows 'none' when the
  ladder is empty). Empty efforts + toggle=False (GLM-4.7 forced) hides it.
- Profile-transition and fetch-failure resets now pass
  supports_thinking_toggle:false alongside the empty efforts so the chip hides
  during the unknown-state window, matching the prior reset contract.

Tests (30 new):
- _zai_glm_classification parametrized across all three tiers + aliases + defer
- get_reasoning_status supports_thinking_toggle per tier (GLM-5.2 both, GLM-4.6
  toggle-only, GLM-4.7 neither, non-zai defaults to effort capability)
- Frontend _applyReasoningChip behavior via node driver: empty efforts +
  toggle=True stays visible, toggle=False hides, effort ladder alone is
  sufficient, absent field keeps prior behavior

State layer: agent.reasoning_effort config + supports_thinking_toggle field in
/api/reasoning + composer chip visibility. Invariant: the chip is hidden ONLY
when the model supports neither the effort ladder nor the thinking toggle
(GLM-4.7 forced, or genuinely non-reasoning models); GLM-4.5-5.1 retain the
working On/None control they had before the round-1 effort gate.

* fix(reasoning): make ZAI thinking toggle two-way + force GLM-4.7 stored none

Address nesquena-hermes round-3 review on #6219 — two SILENT gaps in the
thinking-toggle path, plus a click-handler sibling I found while auditing.

Gap #1 — ONE-WAY toggle for GLM-4.5/4.6/5.0/5.1 (api/config.py:4247,
static/ui.js:4902, static/index.html:757):
The round-2 fix kept the chip visible for thinking-tier models but the only
rendered dropdown option was 'None' (the HTML had no Default option, and
set_reasoning_effort rejected empty effort with 400). So a GLM-4.6 user could
turn thinking OFF but never back ON — worse than the original bug.

Fix:
- set_reasoning_effort now accepts empty effort as 'clear the override' (removes
  agent.reasoning_effort so the provider default takes effect). Invalid values
  still raise ValueError.
- static/index.html gains a <div data-effort=''>Default</div> option.
- _applyReasoningOptions always shows both Default ('') and None alongside the
  effort ladder, so a thinking-tier model (empty ladder + toggle=true) renders
  an operable Default+None two-state control.
- Click handler (ui.js:5106) checks option presence (if(opt)) not truthiness
  (if(effort)) — the old check silently ignored data-effort='' clicks, which
  would have left the Default button dead even after the HTML/backend changes.

Gap #2 — GLM-4.7 not forced when 'none' stored (api/config.py:3984, :3857):
When GLM-4.7 had agent.reasoning_effort=none configured, coercion preserved
'none' via the early return at line 3985, so streaming built disabled reasoning
for a model that forces thinking on regardless. Separately, when the raw
capability source listed 'none', resolve_model_reasoning_efforts reattached it
to GLM-4.7's supported_efforts (['none']), leaking an 'off' option to the UI
for a forced-thinking model.

Fix:
- coerce_reasoning_effort_for_model checks _zai_glm_classification == 'forced'
  BEFORE the generic 'none' early-return, coercing stored 'none' to '' (default
  = thinking on) for forced models.
- resolve_model_reasoning_efforts returns [] early for forced-tier models,
  skipping the 'none' reattachment entirely.

Tests (17 new):
- Gap #2: coerce('none', glm-4.7) -> '', regression guard that non-forced GLM
  still accepts 'none'; resolve does not reattach 'none' for forced but DOES
  for thinking-tier; end-to-end get_reasoning_status for forced+stored-none.
- Gap #1 backend: set('') clears the key (no raise), set('garbage') still
  raises, all 7 valid levels still save.
- Gap #1 frontend: three new node-driver tests asserting the dropdown exposes
  both Default and None for thinking-tier (two-state), Default+None+ladder for
  effort-tier, and the off->on->off round trip keeps both visible throughout.
- Updated test_reasoning_show_hide.test_set_reasoning_effort_rejects_invalid to
  reflect the new contract (empty accepted, garbage rejected).

Regression gate: gap#2 coerce tests fail without the forced-tier check (3
failures); gap#1 backend test fails with 'ValueError: effort is required'
without the empty-acceptance change. 219 passed, 1 pre-existing skip across
the full reasoning + chip + config-cache surface.

State layer: agent.reasoning_effort config + supports_thinking_toggle field +
composer dropdown options. Invariant: the thinking toggle is now genuinely
two-way for GLM-4.5-5.1 (Default=on, None=off, both always visible) and
GLM-4.7 forced-thinking never offers 'none' in any path (coerce, resolve,
status, or UI).
