* fix(auth): prune expired sessions on every verify to prevent memory leak
The in-memory _sessions dict accumulated expired tokens indefinitely —
entries were only removed when that specific token was verified. Add a
lazy _prune_expired_sessions() call at the top of verify_session() so
all expired entries are swept during normal traffic.
Addresses #192.
* test(auth): add 8 unit tests for session lifecycle and lazy pruning
Tests verify:
- Fresh session creation and validation
- Expired entries are pruned during verify_session() calls
- Valid sessions are never removed by pruning
- Empty dict is safe for pruning
- Session TTL matches expected 24-hour window
- invalidate_session() actually removes the token
- Invalidating non-existent tokens is safe
Set Handler.timeout = 30. Python's BaseHTTPRequestHandler.setup()
calls self.request.settimeout(timeout), which raises socket.timeout
on idle or slow connections after the configured duration.
This defends against Slowloris-style attacks where a client holds
connections open indefinitely, exhausting threads in ThreadingHTTPServer.
Also recovers threads from crashed clients with hung TCP connections.
Addresses #194.
* fix: surface approval prompt in UI instead of getting stuck in Thinking
When a dangerous command was detected during streaming, the approval system
would call submit_pending() but no SSE 'approval' event would be emitted to
the frontend. The agent thread either blocked indefinitely (gateway path) or
returned an approval_required status the UI never saw (EXEC_ASK path). Either
way the chat UI stayed stuck in 'Thinking...' with no prompt shown.
Root cause: streaming.py used HERMES_EXEC_ASK=1 but never registered a
register_gateway_notify() callback. Without it, check_all_command_guards()
fell back to the legacy polling path (submit_pending only), which relies on
on_tool() polling -- but on_tool() fires *before* the tool runs, so by the
time the terminal tool detected the dangerous command and called submit_pending,
the approval event had already missed its window.
Fix (streaming.py):
- Register a gateway-style notify_cb via register_gateway_notify() before the
agent runs. The callback calls put('approval', ...) to emit the SSE event
the moment a dangerous command is detected, regardless of on_tool() timing.
- Unregister via unregister_gateway_notify() in the finally block to unblock
any threads still waiting if the stream ends or is cancelled mid-approval.
- Keep the on_tool() fallback poll for older approval module versions.
Fix (routes.py):
- Import and call resolve_gateway_approval() in _handle_approval_respond().
This unblocks the agent thread parked in entry.event.wait() when the user
clicks Allow or Deny in the UI. Without this call the thread would block
until the 5-minute gateway timeout.
Tests (tests/test_approval_unblock.py):
- 16 new tests covering: resolve_gateway_approval() event signalling, deny/
session/once choices, resolve_all, notify_cb registration/firing/cleanup,
unregister signals blocked entries, full end-to-end streaming simulation,
module symbol exports, and HTTP endpoint regressions.
515 tests pass (499 existing + 16 new).

Agent review findings from PR #179:
1. static/ui.js line 542: extra } in ternary produced malformed HTML
in message bubble div (''}} instead of ''}). Caused a literal }
character to appear in the DOM.
2. api/routes.py: LOGIN_INVALID_PW and LOGIN_CONN_FAILED were inserted
into JS string context without JS-string escaping. Added backslash
escaping for ' and \ characters. Currently safe because locale values
are hardcoded, but this prevents breakage if custom locale strings
contain single quotes.

Add applyLocaleToDOM() which walks [data-i18n] elements and re-stamps
their textContent from t(). Called after setLocale() in saveSettings()
so the settings panel labels, checkboxes, and save button update live.
Also called on boot after /api/settings resolves so Chinese persists
without flicker on reload.
- static/i18n.js: add applyLocaleToDOM() function
- static/index.html: add data-i18n attributes to all settings panel
static text nodes (labels, checkbox spans, save button)
- static/panels.js: call applyLocaleToDOM() + syncTopbar() after save
- static/boot.js: call applyLocaleToDOM() alongside setLocale() on boot
Introduces a locale bundle system that makes UI language switchable at
runtime and trivially extensible to any future language.
Architecture:
- static/i18n.js: LOCALES object with 'en' and 'zh' bundles, t(key)
helper with English fallback, setLocale()/loadLocale() for persistence
via localStorage. Adding a new language = adding one object.
- api/config.py: 'language' setting (default 'en'), BCP-47 validation
- api/routes.py: _LOGIN_LOCALE dict for server-rendered login page;
template placeholders substituted at request time from saved setting
- static/index.html: loads i18n.js first (before other scripts); adds
Language dropdown to Settings panel, auto-populated from LOCALES
Wiring:
- boot.js: applies server-persisted locale at startup (after /api/settings
fetch); speech recognition lang follows _locale._speech
- panels.js: populates Language dropdown from LOCALES on settings open;
saves + applies locale on Save Settings
- All JS files: hardcoded user-facing strings replaced with t() calls
Coverage:
- test_sprint20.py: relaxed recognition.lang assertion to accept dynamic
locale-driven assignment (behavior unchanged for English default)
- 499/499 tests pass
Closes#177 (incorporates Chinese translations as a proper locale bundle
rather than hardcoded strings, so English default is fully preserved)
Agent review findings:
- _soundEnabled/_notificationsEnabled not updated in the password-save
early-return branch of saveSettings() — fixed
- AudioContext never closed after oscillator finishes — added osc.onended
callback to ctx.close() preventing resource accumulation

Add two new settings (both default off):
- sound_enabled: plays a short tone via Web Audio API when assistant
finishes a response or requests approval
- notifications_enabled: shows a browser notification when a response
completes while the tab is in the background
Uses Web Audio API (oscillator) instead of bundled MP3 file — zero
additional assets. Follows the standard 4-file settings pattern.
Also skip test_valid_skill_accepted when hermes-agent not installed
(skills endpoint returns 500 without the agent module).

The v0.39.0 security sprint introduced _ENV_LOCK to protect env var
mutations in the streaming path. The implementation held the lock for
the entire agent run (potentially minutes), then tried to re-acquire
it in the finally block — a guaranteed deadlock on any non-reentrant
threading.Lock().
Result: first message completes (done event fires before finally hits),
but the lock is never released. Every subsequent chat/start POST blocks
forever waiting for that lock.
Fix: narrow the lock scope to just the env mutation. Set the vars inside
the with block, then let the lock release before the agent starts. The
finally block re-acquires cleanly since it no longer re-enters an
already-held lock.
No logic change — only the critical section boundary moves.
Hermes stores reasoning as a top-level message field (m.reasoning)
instead of in content arrays like Claude. This patch makes the
thinking/reasoning card also check for m.reasoning, so users can
see the model's reasoning process in the WebUI.
- Added --input-bg and --hover-bg CSS variables to OLED theme
- Added OLED row to built-in themes table in THEMES.md
- Updated theme count from six to seven
True black background with subtle borders for OLED displays.
Pure #000 backgrounds, low-opacity borders, and warm accent colors
to minimize burn-in risk and maximize contrast.
* fix: sync message_count to state.db for /insights (#163)
sync_session_usage() didn't write message_count to state.db, so
/insights showed 0 messages for all WebUI sessions even with
sync_to_insights enabled.
Added message_count parameter to sync_session_usage() and pass
len(s.messages) from both the streaming and non-streaming chat paths.

Tool cards disappeared on page refresh because assistant messages with
only tool_use content (no text) were filtered out of the visible
messages list. Since tool cards anchor to DOM rows via data-msg-idx,
removing the anchor row meant cards had nothing to attach to.
Fix: keep assistant messages in the render list if they contain
tool_use blocks, even when they have no text content. The row renders
with the role label but empty body, providing an anchor point for the
tool card insertion pass.

The previous implementation read SOUL.md files from a filesystem directory.
The Hermes agent uses config.yaml agent.personalities section with string
or dict format (system_prompt, tone, style), resolved via
_resolve_personality_prompt() and passed to AIAgent via
ephemeral_system_prompt.
Changes:
- /api/personalities: reads from config.yaml agent.personalities, not
filesystem SOUL.md directories. Calls reload_config() to pick up
config changes without restart.
- /api/personality/set: resolves prompt from config.yaml using the same
logic as hermes-agent cli.py (string or dict with system_prompt/tone/style)
- streaming.py: passes personality via agent.ephemeral_system_prompt
(agent's own mechanism) instead of prepending to system_message
- Removed unused 're' import from streaming.py
- Updated tests to match config-based approach

The previous fix (#142) prefixed non-default provider models with
'provider/model' which then hit the cross-provider guard and routed
to OpenRouter — worse than before for users without an OpenRouter key.
New approach: non-default provider models use '@provider:model' format
(e.g. @minimax:MiniMax-M2.7). resolve_model_provider() parses this
hint and returns (bare_model, provider, None). streaming.py and
routes.py then pass the resolved provider to
resolve_runtime_provider(requested=provider) which gets the correct
per-provider API key and base_url from hermes-agent.
This uses the agent's own credential resolution instead of reinventing
routing logic in the webui.
