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.
Fixes#163

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
Fixes#139

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.

The model ID `claude-haiku-3-5` does not exist on Anthropic's API and
returns HTTP 404. The correct model is `claude-haiku-4-5` (Claude Haiku 4.5).
Fixes both `_PROVIDER_MODELS` and `_FALLBACK_MODELS` lists.

* feat: /personality slash command with backend integration
Add /personality command to switch the agent's system prompt personality.
Hermes CLI supports personalities stored at ~/.hermes/personalities/<name>/SOUL.md.
Backend:
- GET /api/personalities: lists available personalities from the active
profile's personalities directory (reads first line of SOUL.md for desc)
- POST /api/personality/set: sets active personality on the session, reads
and validates the SOUL.md file exists, returns the prompt text
- streaming.py: injects personality prompt (SOUL.md content) as prefix to
the system_message when run_conversation is called
Frontend (commands.js):
- /personality with no args: lists available personalities as a local message
- /personality <name>: sets the personality with a toast confirmation
- /personality none|default|clear: removes the active personality
Session model: new 'personality' field (backward-compatible, defaults to None)
Closes#139

* fix: path traversal in personality name + case sensitivity
Security: personality name is now validated with regex ^[a-zA-Z0-9][a-zA-Z0-9_-]{0,63}$
in both routes.py (POST /api/personality/set) and streaming.py (system
prompt injection). Defense-in-depth: resolve().relative_to() check ensures
the path stays inside the personalities directory even if regex is bypassed.
Also: removed toLowerCase() from frontend command handler so personality
names are case-preserved (filesystem may be case-sensitive).

* feat: /personality command — hardened, compact() fix, tests
Fixes on top of original PR:
- compact() was missing 'personality' field — UI couldn't know active
personality after page load. Added to Session.compact().
- GET /api/personalities: add symlink guard (is_symlink() skip) and
resolve() check — prevents reading SOUL.md from symlink targets
outside personalities dir.
- POST /api/personality/set: require() only checks session_id (not name)
so clearing with name='' works correctly instead of 400.
- POST /api/personality/set: add MAX_FILE_BYTES size cap on SOUL.md to
prevent unbounded context window consumption.
- POST /api/personality/set: return personality:null (not '') when cleared.
- streaming.py: same MAX_FILE_BYTES guard before prepending to system msg.
Added tests/test_sprint28.py: 11 tests for API round-trip, listing,
symlink guard, path traversal rejection, clear, size cap, persistence.
Tests pass in isolation; full-suite run has a test-isolation interaction
with shared server state across sprint tests (tracked as follow-up).

* fix: prefix non-default provider model IDs for correct routing
When multiple providers are configured, models from non-default providers
(e.g. MiniMax when Anthropic is default) were sent as bare names without
provider context. resolve_model_provider() couldn't determine the target
provider and routed them to the default provider's API, which failed.
Fix: get_available_models() now prefixes model IDs with the provider name
(e.g. minimax/MiniMax-M2.7) for providers that are NOT the active config
provider. The default provider's models keep bare names for direct API
routing. This matches the existing pattern for OpenRouter models.
Added 2 tests to test_model_resolver.py for cross-provider routing.
Closes#138

* fix: model prefix — null-guard, case normalization, mutation safety, tests
Four fixes on top of original PR:
- active_provider=None guard: without a confirmed provider all models were
being prefixed. Only prefix when active_provider is set.
- Case normalisation: compare pid against active_provider.lower() so
config.yaml entries like 'Anthropic' match pid 'anthropic'.
- Mutation safety: default branch used raw reference to _PROVIDER_MODELS[pid];
the default_model injector later calls list.insert() on that reference,
permanently mutating the shared constant. Both branches now use a copy.
- Already-prefixed model IDs pass through as-is (no double-prefix).
Added 3 tests for get_available_models() prefix behaviour:
- Non-default provider models are prefixed
- Active provider's own entries remain bare
- No double-prefix when active_provider is absent

* fix: tool call cards persist correctly after page reload
Root cause: the insertion logic looked for the NEXT assistant row to
insert BEFORE, but when the triggering assistant message contained only
tool_use blocks (no text), it was filtered from the DOM by msgContent()
and no anchor row existed. Cards were silently dropped.
Fix: find the row AT the assistant_msg_idx first (exact match), fall
back to the nearest preceding visible row, then insert AFTER it (not
before the next). This handles both text+tool and tool-only assistant
messages correctly.
Closes#140

* fix: tool card ordering — role-filter fallback anchor, preserve order for same-anchor groups
Two bugs in the initial PR:
- Fallback 'nearest row' had no role filter, could anchor to a user message
row causing cards to appear after a user bubble. Fixed: check role==='assistant'
in the fallback loop.
- Back-to-back tool-card groups sharing a filtered anchor were inserted in
reverse order because each group re-read anchorRow.nextSibling from the live
DOM. Fixed: track the last inserted node per anchor via anchorInsertAfter Map,
so each subsequent group appends after the previous one.
Also restores the 'Collect card elements before they get moved to DOM' comment
explaining why Array.from() is used on frag before DOM insertion.
