Hermes Web UI -- Changelog

[v0.50.87] — 2026-04-18

Fixed

• Streaming scroll override (#677) — auto-scroll no longer hijacks your position while the AI is responding. renderMessages() and appendThinking() now call scrollIfPinned() during an active stream instead of scrollToBottom(), so scrolling up to read earlier content works correctly. Scroll re-pin threshold widened from 80px to 150px to avoid hair-trigger re-pinning on fast mouse wheels. A floating ↓ button appears at the bottom-right of the message area when you scroll up, giving a one-click way to jump back to live output.
• Gemini 3.x model IDs updated (#669) — all provider model lists (gemini, google, OpenRouter fallback, GitHub Copilot, OpenCode Zen, Nous) now include the correct Gemini 3.1 Pro Preview, Gemini 3 Flash Preview, and Gemini 3.1 Flash Lite Preview model IDs alongside stable Gemini 2.5 models. The missing gemini-3.1-flash-lite-preview (which caused API_KEY_INVALID errors) is now present. GEMINI_API_KEY env var now also triggers native gemini provider detection.
• Read-only workspace mount no longer crashes Docker startup (#670) — docker_init.bash now checks [ -w "$HERMES_WEBUI_DEFAULT_WORKSPACE" ] before attempting chown or write-test on the workspace directory. :ro bind-mounts are silently accepted with a log message instead of calling error_exit.
• UID/GID auto-detection now works in two-container setups (#668) — docker_init.bash now probes /home/hermeswebui/.hermes and $HERMES_HOME (shared hermes-home volume) before falling back to /workspace. In Zeabur and Docker Compose two-container deployments where the hermes-agent container initializes the shared volume first, the WebUI now correctly inherits its UID/GID without manual WANTED_UID configuration.

[v0.50.86] — 2026-04-18

Added

• Searchable model picker — the model dropdown now has a live search input at the top. Type any part of a model name or ID to filter the list instantly; provider group headers (Anthropic, OpenAI, OpenRouter, etc.) remain visible in filtered results. Includes a clear button, Escape-to-close support, and a "No models found" empty state. i18n strings added for English, Spanish, and zh-CN. (PR #659 by @mmartial)

Fixed

• _provider_oauth_authenticated() now respects the hermes_home parameter — the function had a CLI fast path (hermes_cli.auth.get_auth_status()) that ignored the caller-supplied hermes_home and read from the real system home. On machines where openai-codex (or another OAuth provider) was genuinely authenticated, this caused three test assertions to return True instead of False, regardless of the isolated tmp_path the test passed in. Removed the CLI fast path; the function now reads exclusively from hermes_home/auth.json, which is both the correct scoped behavior and what the docstring described. No functional change for production (the auth.json path was already the complete fallback). (Fixes pre-existing test_sprint34 failures)

[v0.50.84] — 2026-04-18

Fixed

• MiniMax M2.7 now appears in the model dropdown for OpenRouter users — MiniMax-M2.7 and MiniMax-M2.7-highspeed were present in _PROVIDER_MODELS['minimax'] but absent from _FALLBACK_MODELS, so OpenRouter users (who see the fallback list) never saw them. Both models added to the fallback list under the MiniMax provider label.
• MINIMAX_API_KEY env var now triggers MiniMax detection — the env scan tuple in get_available_models() was missing MINIMAX_API_KEY and MINIMAX_CN_API_KEY, so users who set those vars directly in os.environ (rather than in ~/.hermes/.env) did not see the MiniMax provider in the dropdown. Both keys now scanned. (PR #650 by @octo-patch)

[v0.50.83] — 2026-04-18

Fixed

• Provider models from config.yaml now appear in the model dropdown — users who configured custom providers in config.yaml with an explicit models: list saw the hardcoded _PROVIDER_MODELS fallback instead of their configured models. The fix extends the model-list builder to check cfg.providers[pid].models and use it when present, supporting both dict format (models: {model-id: {context_length: ...}}) and list format (models: [model-id, ...]). Providers only in config.yaml (not in _PROVIDER_MODELS) are now included in the dropdown instead of being silently skipped. (PR #644 by @ccqqlo)

[v0.50.82] — 2026-04-18

Added

• /compress command with optional focus topic — manual session compression runs as a real API call via POST /api/session/compress, replacing the old agent-message-based /compact. Accepts an optional focus topic (/compress summarize code changes) that guides what the compression preserves. The compression flow is shown as three transcript-inline cards: a command card (gold), a running card (blue with animated dots), and a collapsible green success card showing the message-count delta and token savings. A reference card renders the full context compaction summary. /compact continues to work as an alias. focus_topic capped at 500 chars for defense-in-depth. Fallback token estimation uses word-count approximation when model metadata helpers are unavailable — intentional for resilience. (Closes #469, PR #619 by @franksong2702)

[v0.50.81] — 2026-04-18

Fixed

• Auto-title extraction improved for tool-heavy first turns — sessions where the agent's first response involved tool calls (e.g. memory lookups, file reads) were generating poor titles because the title extractor skipped all assistant messages with tool_calls, even when those messages contained substantive visible text. The extractor now picks the first pure (non-tool-call) assistant reply as the title source, using _looks_invalid_generated_title() to distinguish meta-reasoning preambles from real agentic replies. Also fixes _is_provisional_title() to normalize whitespace before comparing, so CJK text truncated at 64 characters correctly re-triggers title updates. (Closes #639, PR #640 by @franksong2702)

[v0.50.80] — 2026-04-18

Fixed

• Clicking a skill no longer silently loads content into a hidden panel — openSkill() now calls ensureWorkspacePreviewVisible() so the workspace panel auto-opens when you click a skill in the Skills tab. (Closes #643)
• Long thinking/reasoning traces now scroll instead of being clipped — the thinking card body now uses overflow-y: auto when open, so long traces are fully readable. (Closes #638)
• Sidebar nav icon hit targets are now correctly aligned — added display:flex; align-items:center; justify-content:center to .nav-tab so clicking the icon itself (not below it) activates the tab. (Closes #636)
• Safari iOS input auto-zoom fixed — bumped textarea#msg base font-size from 14px to 16px, which prevents Safari from zooming the viewport on input focus (Safari zooms when font-size < 16px). Visual difference is negligible. (Closes #630)

[v0.50.79] — 2026-04-17

Fixed

• Default model no longer shows as "(unavailable)" for non-OpenAI users — changed the hardcoded fallback DEFAULT_MODEL from openai/gpt-5.4-mini to "" (empty). When no default model is configured, the WebUI now defers to the active provider's own default instead of pre-selecting an OpenAI model that most providers don't have. Users who want a specific default can still set HERMES_WEBUI_DEFAULT_MODEL env var or pick a model in Preferences. (Closes #646)

[v0.50.78] — 2026-04-17

Fixed

• Gemma 4 thinking tokens no longer shown raw in chat — added <|turn|>thinking\n...<turn|> to the streaming think-token parser in static/messages.js and _strip_thinking_markup() in api/streaming.py. Previously Gemma 4's reasoning output appeared as raw text prepended to the answer. (Closes #607)

[v0.50.77] — 2026-04-17

Changed

• Color scheme system replaced with theme + skin axes — the old monolithic theme list (dark, slate, solarized, monokai, nord, oled, light) is split into two orthogonal axes: theme (light / dark / system) and skin (accent palette: Default gold, Ares red, Mono gray, Slate blue-gray, Poseidon ocean blue, Sisyphus purple, Charizard orange). Users can now mix any theme with any skin via the new Appearance settings tab. Internally, .dark class on <html> replaces data-theme; skin uses data-skin attribute and overrides only 5 accent CSS vars per skin, eliminating ~200 lines of duplicated palette overrides. (PR #627 by @aronprins)

Migration notes

• Legacy theme names are silently migrated on first load to the closest theme + skin pair: slate → dark+slate, solarized → dark+poseidon, monokai → dark+sisyphus, nord → dark+slate, oled → dark+default. Both backend (api/config.py::_normalize_appearance) and frontend (static/boot.js::_normalizeAppearance) apply the same mapping.
• Custom themes set via data-theme CSS overrides will reset to dark + default on first load. The pre-PR theme setting was open-ended ("no enum gate -- allows custom themes"); the new system enumerates valid values. Users who maintained custom CSS will need to re-apply via a skin choice or by overriding skin variables (--accent, --accent-hover, --accent-bg, --accent-bg-strong, --accent-text).

Fixed

• Send button stays active after clearing composer text — input listener now correctly toggles disabled state. (PR #627)
• Composer workspace/model label flash on page load — chips now wait for _bootReady before populating, eliminating the placeholder-then-real-value flicker. (PR #627)
• Topbar border invisible in light mode — added :root:not(.dark) border override. (PR #627)
• User message bubble text contrast — accent-colored bubbles now use skin-aware text colors meeting WCAG AA (Poseidon dark improved from 2.8 → 6.5 ratio). (PR #627)
• Settings skin persistence race condition — save now waits for server confirmation before applying. (PR #627)

[v0.50.76] — 2026-04-17

Fixed

• CSP blocked external images in chat — img-src in the Content Security Policy was restricted to 'self' and data:, causing the browser to block any external image URLs (e.g. from Wikipedia, GitHub, or other HTTPS sources) that the agent rendered in a response. Expanded to img-src 'self' data: https: blob: so external images load correctly. (Closes #608)

[v0.50.75] — 2026-04-17

Fixed

• Test isolation: pytest tests/ was overwriting ~/.hermes/.env with test placeholder keys — two unit tests in test_onboarding_existing_config.py called apply_onboarding_setup() in-process without mocking _get_active_hermes_home, so every test run wrote OPENROUTER_API_KEY=test-key-fresh (or test-key-confirm) to the production .env. Also added HERMES_BASE_HOME to the test server subprocess env (hard-locks profile resolution inside the server to the isolated temp state dir) and stripped real provider keys from the inherited subprocess environment. (PR #620)

[v0.50.71] — 2026-04-16

Fixed

• Docker: HERMES_WEBUI_DEFAULT_WORKSPACE was silently overridden by settings.json — the startup block in api/config.py unconditionally restored the persisted default_workspace, so any container that had previously written settings.json would shadow the env var on the next start. The env var now wins when explicitly set, matching the documented priority order. (Closes #609, PR #610)
• Docker: workspace trust validation rejected subdirectories of DEFAULT_WORKSPACE — resolve_trusted_workspace() only trusted paths under Path.home() or in the saved list; subpaths of a Docker volume mount like /data/workspace/myproject failed with "outside the user home directory". Added a third trust condition for paths under the boot-time DEFAULT_WORKSPACE, which was already validated at startup. (Closes #609, PR #610)

[v0.50.70] — 2026-04-16

Changed

• Chat transcript redesigned — unified --msg-rail/--msg-max CSS variables align all message elements on one column. User turns render as per-theme tinted cards. Thinking cards are bordered panels with gold rule. Inline code inherits --strong. Action toolbar fades in on hover. Error-prefixed assistant rows get [data-error="1"] red-accent card treatment. Day-change .msg-date-sep separators added. Transcript fades to transparent behind composer. (PR #587 by @aronprins)
• Approval and clarify cards as composer flyouts — cards slide up from behind the composer top edge rather than floating as disconnected banners. overflow:hidden outer + translateY inner animation clips travel. focus({preventScroll:true}) prevents autoscrolling. (PR #587 by @aronprins)

Fixed

• Streaming lifecycle stabilised — DOM order stays user → thinking → tool cards → response with no mid-stream jump. Live tool cards inserted inline before the live assistant row. Ghost empty assistant header suppressed on pure-tool turns. (PR #587 by @aronprins)
• Session reload persistence hardened — last-turn reasoning attached before s.save(), so hard-refresh right after a response preserves the thinking trace. role=tool rows preserved in S.messages. CLI-session tool-result fallback parses output envelopes and attaches snippets to matching cards. (PR #587 by @aronprins)
• Workspace panel first-paint flash fixed — [data-workspace-panel] attribute set at document parse time via inline script. (PR #587 by @aronprins)

Added

• docs/ui-ux/index.html — static inventory of every message-area element loading live static/style.css. (PR #587 by @aronprins)
• docs/ui-ux/two-stage-proposal.html — proposal page for the two-stage plan/execute flow (#536). (PR #587 by @aronprins)

[v0.50.69] — 2026-04-16

Fixed

• Docker: workspace file browser no longer appears empty on macOS — docker_init.bash now auto-detects the correct WANTED_UID and WANTED_GID from the mounted /workspace directory at startup. On macOS, host UIDs start at 501 (not 1000), so the default value of 1024 caused the container user to run as a different UID than the files, making the workspace appear empty. The auto-detect reads stat -c '%u' on /workspace and uses it when no explicit WANTED_UID is set — falling back to 1024 if the path doesn't exist or returns 0 (root). Setting WANTED_UID explicitly in a .env file still takes full precedence. (Closes #569)
• Session message count inconsistency resolved — the topbar already correctly shows only visible messages (excluding role='tool' tool-call entries). The sidebar previously showed raw message_count which included tool messages, but PR #584 removed that display entirely — there is no longer any count displayed in the sidebar. No code change needed; documenting with regression tests. (Closes #579)

[v0.50.68] — 2026-04-16

Fixed

• Light theme: add/rename folder dialogs now use correct light colors — .app-dialog, .app-dialog-input, .app-dialog-btn, .app-dialog-close, and .file-rename-input had hardcoded dark-mode backgrounds with no light-theme overrides. Dialog backgrounds, borders, and inputs now adapt correctly to the light theme. (Closes #594)
• Workspace panel no longer snaps open then immediately closed — on page load, boot.js was restoring the panel open/closed state from localStorage before knowing whether the loaded session has a workspace. syncWorkspacePanelState() then snapped it closed, causing a visible jank. The restore is now deferred until after loadSession() and only applied when the session actually has a workspace. (Closes #576)
• Model dropdown reflects CLI model changes without server restart — /api/models was returning a startup-cached snapshot of config.yaml. The fix adds a mtime-based reload check: if config.yaml has changed on disk since last read, the cache is refreshed before building the model list. Page refresh now picks up CLI model changes immediately. (Closes #585)
• Docker Compose: macOS users guided on UID/GID setup — the docker-compose.yml comment for WANTED_UID/WANTED_GID now explicitly notes that macOS UIDs start at 501 (not 1000) and tells users to run id -u/id -g. Also clarifies that the default ${HOME}/.hermes volume mount works on both macOS and Linux. (Closes #567)
• Voice transcription already shows "Transcribing…" spinner — issue #590 noted that no feedback was shown between pressing stop and text appearing. This was already implemented (setComposerStatus('Transcribing…') fires before the fetch in _transcribeBlob). Confirmed and documented; closing as already fixed.

[v0.50.67] — 2026-04-16

Added

• Subpath mount support — Hermes WebUI can now be served behind a reverse proxy at any subpath (e.g. /hermes-webui/ via Tailscale Serve, nginx, or Caddy). A dynamic <base href> is injected as the first script in <head>, and all client-side URL references are converted from absolute to relative. The server-side route handlers are unchanged. No configuration needed — works transparently for both root (/) and subpath deployments. (PR #588 by @vcavichini)

[v0.50.66] — 2026-04-16

Fixed

• WebUI agent now receives full runtime route from provider resolver — previously api_mode, acp_command, acp_args, and credential_pool were not forwarded into AIAgent.__init__() in the WebUI streaming path. Users switching between Codex accounts or using credential pools found the switch worked in the CLI but not the WebUI. The fix passes all four fields from the resolved runtime into the agent constructor. (PR #582 by @suinia)

[v0.50.65] — 2026-04-16

Fixed

• HERMES_WEBUI_SKIP_ONBOARDING=1 now works unconditionally — previously the env var was gated on chat_ready=True, so hosting providers (e.g. Agent37) that set it but hadn't yet wired up a provider key would still see the wizard on every page load. The var is now honoured as a hard operator override regardless of chat_ready. If you set it, the wizard is gone. (Fixes skip-onboarding regression)
• Onboarding wizard can no longer overwrite config or env files when SKIP_ONBOARDING is set — apply_onboarding_setup now checks the env var first and refuses to touch config.yaml or .env if it is set. This is a belt-and-suspenders guard: even if a stale JS bundle somehow triggers the setup endpoint while SKIP_ONBOARDING is active, no files are written.

[v0.50.64] — 2026-04-16

Changed

• Sidebar session items decluttered — the meta row under every session title (message count, model slug, and source-tag badge) has been removed. Each session now renders as a single line: title + relative-time bucket headers. The visible session count at a typical viewport height roughly doubles. The source_tag field is still populated on the session object and available for a future tooltip or filter facet. [SYSTEM:]-prefixed gateway titles fall back to "Session" rather than leaking system-prompt content. Removes _formatSourceTag(), .session-meta, cli-session, [data-source=…], _SOURCE_DISPLAY, and the associated CSS badge rules. (PR #584 by @aronprins)

[v0.50.63] — 2026-04-16

Fixed

• Onboarding wizard no longer fires for non-standard providers — providers outside the quick-setup list (minimax-cn, deepseek, xai, gemini, etc.) were always evaluated as chat_ready=False because _provider_api_key_present() only knew the four built-in env-var names. Those users saw the wizard on every page load and risked config.yaml being silently overwritten if the provider dropdown defaulted. The fix adds a hermes_cli.auth.get_auth_status() fallback covering every API-key provider in the full registry, and tightens the frontend guard so an unchanged unsupported-provider form never POSTs. (Fixes #572, PR #575)
• MCP server toolsets now included in WebUI agent sessions — previously the WebUI read platform_toolsets.cli directly from config.yaml, which only carries built-in toolset names. MCP server names (tidb, kyuubi, etc.) were silently dropped, so MCP tools configured via ~/.hermes/config.yaml were unavailable in chat. The fix delegates to hermes_cli.tools_config._get_platform_tools() — the same code the CLI uses — which merges all enabled MCP servers automatically. Falls back gracefully when hermes_cli is unavailable. (PR #574 by @renheqiang)

[v0.50.62] — 2026-04-16

Fixed

• Docker startup no longer hard-exits when hermes-agent source is not mounted — previously docker_init.bash would call error_exit if the agent source directory was missing, preventing the container from starting at all. Users running a minimal docker run without the two-container compose setup hit this immediately. Now the script checks for the directory and pyproject.toml first, prints a clear warning explaining reduced functionality, and continues startup. The WebUI already has try/except fallbacks throughout for when hermes-agent is unavailable. (Fixes #570, PR #573)

[v0.50.61] — 2026-04-16

Added

• Office file attachments — .xls, .xlsx, .doc, and .docx files can now be selected via the attach button. The file picker's accept attribute is extended to include Office MIME types, and the backend MIME map is updated so these files are served with correct content-type headers when accessed through the workspace file browser. Files are saved as binary to the workspace; the AI can reference them by name the same way it does PDFs. (PR #566 by @renheqiang)

[v0.50.60] — 2026-04-16

Changed

• Test robustness — two onboarding setup tests (test_setup_allowed_with_confirm_overwrite, test_setup_allowed_when_no_config_exists) now skip gracefully when PyYAML is not installed in the test environment, matching the pattern already used in test_onboarding_mvp.py. No production code changed. (PR #564)

[v0.50.59] — 2026-04-16

Fixed

• False "Connection lost" message after settled stream — the UI no longer injects a fake **Error:** Connection lost assistant message when an SSE connection drops after the stream already completed normally. The fix tracks terminal stream states (done, stream_end, cancel, apperror) and, on a disconnect, fetches /api/session to confirm the session is settled before silently restoring it instead of calling the error path. Real failures still go through the error path as before. (Fixes #561, PR #562 by @halmisen)

[v0.50.58] — 2026-04-16

Fixed

• Custom provider name in model dropdown — when a custom_providers entry in config.yaml has a name field (e.g. Agent37), the model picker now shows that name as the group header instead of the generic Custom label. Multiple named providers each get their own group. Unnamed entries still fall back to Custom. Brings the web UI into parity with the terminal's provider display. (Fixes #557)

[v0.50.57] — 2026-04-15

Added

• Auto-generated session titles — after the first exchange, a background thread generates a concise title from the first user message and assistant reply, replacing the default first-message substring. Updates live in the UI via a new title SSE event. Manual renames are preserved; generation only runs once per session. Includes MiniMax token budget handling and a local heuristic fallback. (Fixes #495, PR #535 by @franksong2702)

Changed

• SSE stream termination — streams now end with stream_end instead of done so the background title generation thread has time to emit the title update before the client disconnects.

[v0.50.55] — 2026-04-15

Fixed

• Docker honcho extra — docker_init.bash now installs hermes-agent[honcho] so honcho-ai is included in the venv on every fresh Docker build. Fixes "Honcho session could not be initialized." errors on rebuilt containers. (Fixes #553)
• Version badge — index.html version badge corrected to v0.50.55 (was missing the bump for this release).

[v0.50.54] — 2026-04-15

Changed

• OpenRouter model list — updated to 14 current models across 7 providers. All slugs verified live against the OpenRouter catalog. Removed o4-mini, old Gemini 2.x entries, and Llama 4. Added Claude Opus 4.6, GPT-5.4, Gemini 3.1 Pro Preview, Gemini 3 Flash Preview, DeepSeek R1, Qwen3 Coder, Qwen3.6 Plus, Grok 4.20, and Mistral Large. Both Claude 4.6 and 4.5 generations preserved. Fixed grok-4-20 → grok-4.20 slug and Gemini -preview suffixes.

[v0.50.53] — 2026-04-15

Fixed

• Custom endpoint slash model IDs — model IDs with vendor prefixes that are intrinsic (e.g. zai-org/GLM-5.1 on DeepInfra) are now preserved when routing to a custom base_url endpoint. Previously, all prefixed IDs were stripped, causing model_not_found errors on providers that require the full vendor/model format. Known provider namespaces (openai/, google/, anthropic/, etc.) are still stripped as before. (Fixes #548, PR #549 by @eba8)

[v0.50.52] — 2026-04-15

Fixed

• Simultaneous approval requests — parallel tool calls that each require approval no longer overwrite each other. _pending is now a list per session; each entry gets a stable approval_id (uuid4) so /api/approval/respond can target a specific request. The UI shows a "1 of N pending" counter when multiple approvals are queued. Backward-compatible with old agent versions and old frontend clients. Adds 14 regression tests. (Fixes #527)

[v0.50.51] — 2026-04-15

Fixed

• Orphaned tool messages — conversation histories containing role: tool messages with no matching tool_call_id in a prior assistant message are now silently stripped before sending to the provider API. Fixes 400 errors from strictly-conformant providers (Mercury-2/Inception, newer OpenAI models). Adds 13 regression tests. (Fixes #534)

[v0.50.50] — 2026-04-15

Fixed

• Code block syntax highlighting — Prism theme now follows the active UI theme. Light mode uses the default Prism light theme; dark mode uses prism-tomorrow. Theme swaps happen immediately on toggle including on first load. Adds id="prism-theme" to the Prism CSS link so JavaScript can locate and swap it. (Closes #505, PR #530 by @mariosam95)

[v0.50.49] — 2026-04-15

Fixed

• IME composition — isComposing guard added to every Enter keydown handler so CJK/Japanese/Korean input method users never accidentally send mid-composition (fixes #531). Covers chat composer, command dropdown, session rename, project create/rename, app dialog, message edit, and workspace rename. Adds 3 regression tests. (PR #537 by @vansour)

[v0.50.48] fix: toast when model is switched during active session (#419)

Synthesized from PRs #516 (armorbreak001), #517 and #518 (cloudyun888).

When a user switches the model via the model picker while a session already has messages, a 3-second toast now reads: "Model change takes effect in your next conversation." This avoids the confusing situation where the dropdown shows the new model but the current conversation continues with the original one.

The toast fires from modelSelect.onchange in static/boot.js, after the existing provider-mismatch warning. It checks S.messages.length > 0 (the reliable in-memory array, always initialized by loadSession). The showToast call is guarded with typeof for safety during boot.

Key differences from submitted PRs: placement in boot.js onchange (covers all selection paths including chip dropdown, since selectModelFromDropdown calls sel.onchange), and uses S.messages not S.session.messages.

4 new tests in tests/test_provider_mismatch.py::TestModelSwitchToast.

Total tests: 1272 (was 1268)

[v0.50.47] fix/feat: batch fixes — root workspace, custom providers, cron cache, system theme

Synthesized from PRs #506, #507, #508, #509, #510, #514, #515, #519, #521.

Fixes

Allow /root as a workspace path (PRs #510, #521 by @ccqqlo) Removes /root from _BLOCKED_SYSTEM_ROOTS in api/workspace.py, so deployments running as root (Docker, VPS) can set /root as their workspace without a "system directory" rejection.

Guard against split on missing [Attached files:] (PR #521 by @ccqqlo) base_text extraction in api/streaming.py now guards: msg_text.split(...)[0] if ... in msg_text else msg_text. Previously split on the empty case returned an empty string, causing attachment-matching to silently fail on messages with no attachments.

custom_providers models visible regardless of active provider (#515, #519 by @shruggr, @cloudyun888) get_available_models() in api/config.py no longer discards the 'custom' provider from detected_providers when the user has custom_providers entries in config.yaml. Previously, switching active_provider away from 'custom' hid all custom model definitions from the picker.

Cron skill picker cache invalidated on form open and skill save (PRs #507, #508 by @armorbreak001) toggleCronForm() now unconditionally nulls _cronSkillsCache before fetching, so skills created in the same session appear immediately. submitSkillSave() also nulls _cronSkillsCache after a successful write, mirroring the existing _skillsData = null pattern. Fixes #502.

Features

System (auto) theme following OS prefers-color-scheme (#504 / PRs #506, #509, #514 by @armorbreak001, @cloudyun888) New "System (auto)" option in the theme picker follows the OS dark/light preference via window.matchMedia. Changes:

• static/boot.js: _applyTheme(name) helper resolves 'system' via matchMedia, sets data-theme, and registers a MQ change listener for live OS tracking. loadSettings() calls _applyTheme() instead of direct assignment.
• static/index.html: flicker-prevention script resolves 'system' before first paint. Adds "System (auto)" as first theme option. onchange calls _applyTheme().
• static/commands.js: adds 'system' to valid /theme names.
• static/panels.js: _settingsThemeOnOpen reads from localStorage (preserves 'system' string). _revertSettingsPreview calls _applyTheme().
• static/i18n.js: cmd_theme description lists 'system' first in all 5 locales.

Tests

22 new tests in tests/test_batch_fixes.py.

Total tests: 1268 (was 1246)

[v0.50.46] feat: clarify dialog flow and refresh recovery (#520)

Adds a full clarify dialog UX for interactive agent questions — modeled after the approval card but for free-form clarification prompts.

Backend

New api/clarify.py module with a per-session pending queue backed by threading.Event unblocking, gateway notify callbacks, duplicate deduplication while unresolved, and resolve/clear helpers.

Three new HTTP endpoints in api/routes.py:

• GET /api/clarify/pending — poll for pending clarify prompt
• POST /api/clarify/respond — resolve the pending prompt
• GET /api/clarify/inject_test — loopback-only, for automated tests

api/streaming.py wires clarify_callback into AIAgent.run_conversation(). Emits clarify SSE events; blocks the tool flow until the user responds, times out (120s), or the stream is cancelled. Also adds a 409 guard on chat/start so page-refresh races return the active stream id instead of starting a duplicate.

Frontend

static/messages.js: clarify card with numbered choices, Other button, and free-text input. Composer is locked while clarify is active. DOM self-heals if the card node is removed during a rerender. SSE clarify event listener plus 1.5s fallback polling. Session switch and reconnect start/stop clarify polling. 409 conflict flow reattaches to the active stream and queues the user message. CLARIFY_MIN_VISIBLE_MS = 30000 timer dedup mirrors the approval card pattern.

static/ui.js: lockComposerForClarify() / unlockComposerForClarify() with saved-state restore. updateSendBtn() respects the disabled state.

static/sessions.js: loadSession() starts/stops clarify polling on switch and inflight reattach.

static/index.html / static/style.css: clarify card markup with ARIA roles and full responsive/mobile styles.

static/i18n.js: 6 new keys in all 5 locales (en, es, de, zh-Hans, zh-Hant).

Tests

• tests/test_clarify_unblock.py: 14 new tests covering queue resolution, notify callbacks, clear-on-cancel, and all three HTTP endpoints.
• tests/test_sprint30.py: 31 new clarify tests (HTML markup, CSS classes, i18n keys, messages.js functions, streaming registration flags).
• tests/test_sprint36.py: expand search window for setBusy check after additional stopClarifyPolling() calls push it past the old 800-char limit.

[v0.50.45] fix: suppress N/A source_tag in session list (#429)

Feishu and WeChat sessions (and any session with an unrecognised or legacy source value in hermes-agent's state.db) were showing "N/A" or raw tag strings in the session list sidebar.

Three fixes in static/sessions.js:

1. _formatSourceTag() now returns null for unrecognised tags instead of the raw string. Known platforms (telegram, discord, slack, feishu, weixin, cli) still display their human-readable label. Unknown/legacy values are silently suppressed.

2. The metaBits push is guarded: stores the result in _stLabel and only pushes if it is non-null. Prevents null or unrecognised platform names from appearing in the session metadata line.

3. The [SYSTEM:] title fallback now uses _SOURCE_DISPLAY[s.source_tag] || 'Gateway' — the raw s.source_tag middle term is removed so a session whose source is "N/A" does not use that as its visible title.

No backend changes. The upstream issue (hermes-agent not reliably setting source for older Feishu/WeChat sessions) is tracked separately.

7 new tests in tests/test_issue429.py. Updated 1 existing test in tests/test_sprint40_ui_polish.py to match the new guarded push pattern.

[v0.50.44] fix: code-in-table CSS sizing + markdown image rendering (#486, #487)

CSS: inline code inside table cells (fixes #486)

Inline `code` spans inside <td> and <th> cells were rendering too large relative to the cell height — the .msg-body code rule sets 12.5px which sits awkward against the table's 12px base font.

Fix: added two targeted rules in static/style.css:

.msg-body td code,.msg-body th code { font-size:0.85em; padding:1px 4px; vertical-align:baseline; }
.preview-md td code,.preview-md th code { font-size:0.85em; padding:1px 4px; vertical-align:baseline; }

Covers both the chat message surface (.msg-body) and the markdown preview panel (.preview-md).

JS renderer: ![alt](url) image syntax (fixes #487)

Standard markdown image syntax was not handled by renderMd(). The ! was left as a stray character and [alt](url) was consumed by the link pass, producing ! <a href="url">alt</a> instead of an <img>.

Fix: added an image pass to both inlineMd() (for images in table cells, list items, blockquotes, headings) and the outer renderMd() pipeline (for images in plain paragraphs):

• Regex: ![alt](https?://url) — only http:// and https:// URIs accepted; javascript: and data: URIs cannot match.
• Alt text passes through esc() — XSS-safe.
• URL double-quotes percent-encoded to %22 — attribute breakout prevented.
• Reuses .msg-media-img class — same click-to-zoom and max-width styling as agent-emitted MEDIA: images.
• img added to SAFE_TAGS allowlist so the generated <img> is not escaped.
• In inlineMd(): image pass runs while the _code_stash is still active, so ![alt](url) inside a backtick span stays protected and is never rendered as an image. A new _img_stash (\x00G) protects rendered <img> tags from the autolink pass touching src= values.

Tests

45 new tests in tests/test_issue486_487.py:

[v0.50.43] fix: markdown link rendering + KaTeX CSP fonts

Markdown link rendering — renderMd() in static/ui.js (PR #475, fixes #470)

Three related bugs fixed:

1. Double-linking via autolink pass — [label](url) was converted to <a href="...">, then the bare-URL autolink pass re-matched the URL sitting inside href="..." and wrapped it in a second <a> tag. Fixed with three stash/restore layers: \x00L (inlineMd labeled links), \x00A (existing <a> tags before outer link pass), \x00B (existing <a> tags before autolink pass).

2. esc() on href values corrupts query strings — esc() is HTML-entity encoding; applying it to URLs converted & → & in query strings. Removed esc() from href values in all three locations. Display text (link labels) still uses esc() for XSS safety. " in URLs replaced with %22 (URL encoding) to close the attribute-injection vector identified during review.

3. Backtick code spans inside **bold** rendered as <code> — esc() was applied to code spans after bold/italic processing. Added \x00C stash to protect backtick spans in inlineMd() before bold/italic regex runs.

Security audit: javascript: injection blocked by https?:// prefix requirement. " attribute breakout fixed by .replace(/"/g, '%22'). Label/display text still HTML-escaped.

24 tests in tests/test_issue470.py.

KaTeX CSP font-src (fixes #477)

api/helpers.py CSP font-src now includes https://cdn.jsdelivr.net so KaTeX math rendering fonts load correctly. Previously ~50 CSP font-blocking errors appeared in the console on any page with math content. The CDN was already allowed in script-src and style-src for KaTeX JS/CSS — this extends the same allowance to fonts.

[v0.50.42] fix: session display + model UX polish (sprint 42)

Context indicator always shows latest usage (PR #471, fixes #437) The context ring/indicator in the composer footer was reading token counts and cost from the stored session snapshot with || — meaning stale non-zero values from previous turns always won over a fresh 0 from the current turn. Replaced all six field merges with a _pick(latest, stored, dflt) helper that correctly prefers the latest usage when it's a real value (including 0).

System prompt no longer leaks as gateway session title (PR #472, fixes #441) Telegram, Discord, and CLI gateway sessions inject a system message before any user turn. When the session title is set from this message, the sidebar shows [SYSTEM: The user has inv... instead of a meaningful name. Added a guard in _renderOneSession(): if cleanTitle starts with [SYSTEM:, replace it with the platform display name (Telegram session, Discord session, etc.).

Thinking/reasoning panel persists across page reload (PR #473, fixes #427) The full chain-of-thought from Claude, Gemini, and DeepSeek thinking models was lost after streaming completed and on every page reload. Two-part fix:

• api/streaming.py: on_reasoning() now accumulates _reasoning_text; before the session is serialised at stream end, _reasoning_text is injected into the last assistant message so it's stored in the session JSON
• static/messages.js: in the done SSE handler, reasoningText is also patched onto the last assistant message as a belt-and-suspenders client-side fallback

Custom model ID input in model picker (PR #474, fixes #444) Users who need a model not in the curated list (~30 models) can now type any model ID directly in the dropdown. A text input at the bottom of the model picker lets users enter any string (e.g. openai/gpt-5.4, deepseek/deepseek-r2, or any provider-prefixed ID) and press Enter or click + to use it immediately. i18n keys added to en, es, zh.

[v0.50.41] feat(ui): render MEDIA: images inline in web UI chat (fixes #450)

When the agent outputs MEDIA:<path> tokens — screenshots from the browser tool, generated images, vision outputs — the web UI now renders them inline in the chat, the same way Claude.ai handles images. No more relaying screenshots through Telegram.

How it works:

• Local image path (MEDIA:/tmp/screenshot.png): rendered as <img> via /api/media?path=...
• HTTP(S) URL to image (MEDIA:https://example.com/img.png): <img> directly from the URL
• Non-image file (MEDIA:/tmp/report.pdf): styled download link (📎 filename)
• Click any inline image to toggle full-size zoom

New endpoint — GET /api/media?path=<encoded-path>:

• Path allowlist: ~/.hermes/, /tmp/, active workspace — covers all agent output locations
• Auth-gated: requires valid session cookie when auth is enabled
• Inline image MIME types: PNG, JPEG, GIF, WebP, BMP
• SVG always served as download attachment (XSS prevention)
• RFC 5987-compliant Content-Disposition headers (handles Unicode filenames)
• Cache-Control: private, max-age=3600

Security:

• Original version had ~ (entire home dir) as an allowed root — fixed by independent reviewer
• Restricted to ~/.hermes/, /tmp/, and active workspace only
• Path.resolve() + commonpath checks prevent symlink traversal

Changes:

• api/routes.py: _handle_media() handler + /api/media route

• static/ui.js: MEDIA: stash in renderMd() (runs before fence_stash, stash token \x00D)

• static/style.css: .msg-media-img (480px max-width, zoom-on-click), .msg-media-link

• tests/test_media_inline.py: 19 new tests (static analysis + integration)

• Total tests: 1117 (was 1098)

[v0.50.40] feat: session UI polish + parallel test isolation

Session sidebar improvements:

• static/sessions.js + style.css: Hide session timestamps to give titles full available width — no more title truncation from inline timestamps (PR #449)
• static/style.css: Active session title now uses var(--gold) theme variable instead of hardcoded #e8a030 — adapts correctly across all 7 themes (PR #451, fixes #440)
• api/models.py + api/gateway_watcher.py: Return None instead of the string 'unknown' for missing gateway session model — Telegram sessions no longer show telegram · unknown (PR #452, fixes #443)
• static/style.css + static/sessions.js: Mute Telegram badge from saturated #0088cc to rgba(0, 136, 204, 0.55). Add _formatSourceTag() helper mapping platform IDs to display names (telegram → via Telegram) (PR #453, fixes #442)

Bug fixes:

• api/config.py resolve_model_provider(): Strip provider prefix from model ID when a custom base_url is configured (openai/gpt-5.4 → gpt-5.4) — fixes broken chats after switching to a custom endpoint (PR #454, fixes #433)
• static/panels.js switchToProfile(): Apply profile default workspace to new session created during profile switch — workspace chip no longer shows "No active workspace" after switching profiles mid-conversation (PR #455, fixes #424)

Test infrastructure:

• tests/conftest.py + tests/_pytest_port.py (new): Auto-derive unique port and state dir per worktree from repo path hash (range 20000-29999). Running pytest in two worktrees simultaneously no longer causes port conflicts. All 43 test files updated from hardcoded BASE = "http://127.0.0.1:8788" to from tests._pytest_port import BASE (PR #456)

[v0.50.39] fix: orphan gateway sessions + first-password-enablement session continuity

Two bug fixes:

PR #423 — Fix orphan gateway sessions in sidebar (@aronprins, fix by maintainer) gateway_watcher.py's _get_agent_sessions_from_db() was missing the HAVING COUNT(m.id) > 0 clause that get_cli_sessions() already had. Sessions with no messages (e.g. created then abandoned before any turns) would appear in the sidebar via the SSE watcher stream even after the initial page load filtered them out. One-line SQL fix applied to both query paths.

PR #434 — First-password-enablement session continuity (@SaulgoodMan-C) When a user enables a password for the first time via POST /api/settings, the current browser session was being terminated — requiring the user to log in again immediately after setting their password. Fix: the response now includes auth_enabled, logged_in, and auth_just_enabled fields, and issues a hermes_session cookie when auth is first enabled, so the browser remains logged in. Also: legacy assistant_language key is now dropped from settings on next save. New i18n keys for password replacement/keep-existing states (en, es, de, zh, zh-Hant).

• api/config.py: _SETTINGS_LEGACY_DROP_KEYS removes assistant_language on load

• api/routes.py: first-password-enable session continuity with auth_just_enabled flag

• static/panels.js: _setSettingsAuthButtonsVisible() + _applySavedSettingsUi() helpers

• static/i18n.js: password state i18n keys across 5 locales

• tests/test_sprint45.py: 3 new integration tests (auth continuity + legacy key cleanup)

Three community contributions combined:

PR #425 — Remove mobile bottom nav (@aronprins) The fixed iOS-style bottom navigation bar on phones has been removed. The sidebar drawer tabs already handle all navigation — the bottom nav was redundant and consumed ~56px of vertical chat space. test_mobile_layout.py updated with test_mobile_bottom_nav_removed() and new sidebar nav coverage tests.

PR #426 — Prism syntax highlighting with light + dark theme token colors (@GiggleSamurai) Fenced code blocks now emit class="language-{lang}" on <code> elements, enabling Prism's autoloader to apply token-level syntax highlighting. Added 36-line :root[data-theme="light"] token color overrides scoped to light theme only; dark/dim/monokai/nord themes unaffected. Background guard uses var(--code-bg) !important to prevent Prism's dark background from overriding theme variables. 2 new regression tests in test_issue_code_syntax_highlight.py.

PR #428 — zh-CN/zh-Hant i18n hardening (@vansour) Pluggable resolvePreferredLocale() function with smart zh-CN/zh-SG/zh-TW/zh-HK variant mapping. Full zh-Simplified and zh-Traditional locale blocks added to i18n.js. Login page locale routing updated in api/routes.py (_resolve_login_locale_key() helper).

[v0.50.37] fix(onboarding): skip wizard when Hermes is already configured

Fixes #420 — existing Hermes users with a valid config.yaml were shown the first-run onboarding wizard on every WebUI load because the only completion gate was settings.onboarding_completed in the WebUI's own settings file. Users who configured Hermes via the CLI before the WebUI existed had no such flag, so the wizard always fired and could silently overwrite their working config.

Changes:

1. api/onboarding.py get_onboarding_status(): auto-complete when config.yaml exists AND chat_ready=True. Existing configured users are never shown the wizard.
2. api/onboarding.py apply_onboarding_setup(): refuse to overwrite an existing config.yaml without confirm_overwrite=True in the request body. Returns {error: "config_exists", requires_confirm: true} for the frontend to handle.
3. static/index.html: "Skip setup" button added to wizard footer — users are never trapped in the wizard.
4. static/onboarding.js: skipOnboarding() calls /api/onboarding/complete without modifying config, then closes the overlay.
5. static/boot.js: Escape key now dismisses the onboarding overlay.
6. static/i18n.js: onboarding_skip / onboarding_skipped keys added to en + es locales.
7. tests/test_onboarding_existing_config.py: 8 new unit tests covering gate logic and overwrite guard.

[v0.50.36] fix: workspace list cleaner — allow own-profile paths, remove brittle string filter

Two bugs in _clean_workspace_list() caused workspace additions to silently disappear on the next load_workspaces() call, breaking test_workspace_add_no_duplicate and test_workspace_rename (and potentially causing real-world workspace list corruption):

Bug 1 — Brittle string filter removed: if 'test-workspace' in path or 'webui-mvp-test' in path: continue dropped any workspace path containing those substrings. In the test server, TEST_WORKSPACE is ~/.hermes/profiles/webui/webui-mvp-test/test-workspace, so every workspace added during tests was silently discarded on the next load_workspaces() call. The p.is_dir() check already handles genuinely non-existent paths — the string filter was redundant and harmful.

Bug 2 — Cross-profile filter was too broad: if p is under ~/.hermes/profiles/: skip was designed to block cross-profile workspace leakage, but it also removed paths under the current profile's own directory (e.g. ~/.hermes/profiles/webui/...). Fixed: now only skips paths under profiles/ that are NOT under the current profile's own hermes_home.

• api/workspace.py: remove string-match filter; fix cross-profile check to allow own-profile paths
• All 1055 tests now pass (was 1053 pass + 2 fail)

[v0.50.35] fix: workspace trust boundary — cross-platform, multi-workspace support

v0.50.34's workspace trust check was too restrictive: it required all workspaces to be under DEFAULT_WORKSPACE (/home/hermes/workspace), which blocked every profile-specific workspace (~/CodePath, ~/hermes-webui-public, ~/WebUI, ~/Camanji, etc.) and prevented switching between workspaces at all.

Replaced with a three-layer model that works cross-platform and supports multiple workspaces per profile:

1. Blocklist — /etc, /usr, /var, /bin, /sbin, /boot, /proc, /sys, /dev, /root, /lib, /lib64, /opt/homebrew always rejected, closing the original CVSS 8.8 vulnerability
2. Home-directory check — any path under Path.home() is trusted; Path.home() is cross-platform (~/... on Linux/macOS, C:\\Users\\... on Windows); allows all profile workspaces simultaneously since they don't need to share a single ancestor
3. Saved-workspace escape hatch — paths already in the profile's saved workspace list are trusted regardless of location, covering self-hosted deployments with workspaces outside home (/data/projects, /opt/workspace, etc.)

• api/workspace.py: rewritten resolve_trusted_workspace() with the three-layer model
• tests/test_sprint3.py: updated error-message assertions from "trusted workspace root" → "outside" (covers both old and new error strings)
• 1053 tests total (unchanged)

[v0.50.34] fix(workspace): restrict session workspaces to trusted roots [SECURITY] (#415)

Session creation, update, chat-start, and workspace-add endpoints accepted arbitrary caller-supplied workspace paths. An authenticated caller could repoint a session to any directory the process could access, then use normal file read/write APIs to operate on attacker-chosen locations. CVSS 8.8 High (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

• api/workspace.py: new resolve_trusted_workspace(path) helper — resolves path, checks existence + is_dir, enforces path.relative_to(_BOOT_DEFAULT_WORKSPACE) containment; requests outside the WebUI workspace root fail with 400
• api/routes.py: apply resolve_trusted_workspace() to all four entry points — POST /api/session/new, POST /api/session/update, POST /api/chat/start (workspace override), POST /api/workspaces/add
• tests/test_sprint3.py, tests/test_sprint5.py: regression tests for rejected outside-root paths on all four entry points; existing workspace tests updated to use trusted child directories
• tests/test_sprint1.py, tests/test_sprint4.py, tests/test_sprint13.py: aligned to new trusted-root contract
• Fix: use _BOOT_DEFAULT_WORKSPACE (respects HERMES_WEBUI_DEFAULT_WORKSPACE env for test isolation) rather than _profile_default_workspace() (reads agent terminal.cwd which may differ)

[v0.50.33] fix: workspace panel close button — no duplicate X on desktop, mobile X respects file preview (#413)

Bug 1 — Duplicate X on desktop: #btnClearPreview (the X icon) was always visible regardless of panel state, so desktop browse mode showed both the chevron collapse button and the X simultaneously. Fixed in syncWorkspacePanelUI(): on non-compact (desktop) viewports, clearBtn.style.display is set to none when no file preview is open, and cleared (shown) when a preview is active.

Bug 2 — Mobile X collapsed the whole panel instead of dismissing the file: .mobile-close-btn was wired to closeWorkspacePanel() directly, bypassing the two-step close logic. Fixed by changing onclick to handleWorkspaceClose(), which calls clearPreview() first if a file is open, and falls through to closeWorkspacePanel() otherwise.

Also: widened the test_server_delete_invalidates_index window from 600 → 1200 chars to accommodate the session_id validation guards added in v0.50.32 (#412).

• static/boot.js: syncWorkspacePanelUI() sets clearBtn.style.display based on hasPreview when !isCompact
• static/index.html: .mobile-close-btn onclick changed from closeWorkspacePanel() to handleWorkspaceClose()
• tests/test_sprint44.py: 10 new regression tests covering both fixes

[v0.50.32] fix(sessions): validate session_id before deleting session files [SECURITY] (#409)

/api/session/delete accepted arbitrary session_id values from the request body and built the delete path directly as SESSION_DIR / f"{sid}.json". Because pathlib discards the prefix when sid is an absolute path, an attacker could supply /tmp/victim and cause the server to unlink victim.json outside the session store. Traversal-style values (../../etc/target) were also accepted. CVSS 8.1 High (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H).

• api/routes.py: validate session_id against [0-9a-z_]+ allowlist (covers uuid4().hex[:12] WebUI IDs and YYYYMMDD_HHMMSS_hex CLI IDs) before path construction; resolve candidate path and enforce path.relative_to(SESSION_DIR) containment before unlinking; only invalidate session index on successful deletion path, not on rejected requests

[v0.50.31] fix: delegate all live model fetching to agent's provider_model_ids()

_handle_live_models() in api/routes.py previously maintained its own per-provider fetch logic and returned not_supported for Anthropic, Google, and Gemini. Now it delegates entirely to the agent's hermes_cli.models.provider_model_ids() — the single authoritative resolver — and _fetchLiveModels() in ui.js no longer skips any provider.

What each provider now returns (live data where credentials are present, static fallback otherwise):

• anthropic — live from api.anthropic.com/v1/models (API key or OAuth token with correct beta headers)
• copilot — live from api.githubcopilot.com/models with required Copilot headers
• openai-codex — Codex OAuth endpoint → ~/.codex/ cache → DEFAULT_CODEX_MODELS
• nous — live from Nous inference portal
• deepseek, kimi-coding — generic OpenAI-compat /v1/models
• opencode-zen, opencode-go — OpenCode live catalog
• openrouter — curated static list (live returns 300+ which floods the picker)
• google, gemini, zai, minimax — static list (non-standard or Anthropic-compat endpoints)
• All others — graceful static fallback from _PROVIDER_MODELS

The hardcoded lists in _PROVIDER_MODELS remain as credential-missing / network-unavailable fallbacks. api/routes.py shrank by ~100 lines. Updated 2 tests to reflect the improved behavior.

[v0.50.30] fix: openai-codex live model fetch routes through agent's get_codex_model_ids()

_handle_live_models() was grouping openai-codex with openai and sending GET https://api.openai.com/v1/models — which returns 403 because Codex auth is OAuth-based via chatgpt.com, not a standard API key. The live fetch silently failed, so users only ever saw the hardcoded static list.

• api/routes.py: dedicated early-return branch for openai-codex that calls hermes_cli.codex_models.get_codex_model_ids() — the same resolver the agent CLI uses. Resolution order: live Codex API (if OAuth token available, hits chatgpt.com/backend-api/codex/models) → ~/.codex/ local cache (written by the Codex CLI) → DEFAULT_CODEX_MODELS hardcoded fallback. Users with a valid Codex session now get their exact subscription model list including any models not in the hardcoded list.
• api/routes.py: improved label generation for Codex model IDs (e.g. gpt-5.4-mini → GPT 5.4 Mini)

[v0.50.29] fix: correct tool call card rendering on session load after context compaction (closes #401) (#402)

• static/sessions.js: replace the flat B9 filter in loadSession() with a full sanitization pass that builds origIdxToSanitizedIdx — each session.tool_calls[].assistant_msg_idx is remapped to the new sanitized-array position as messages are filtered; for tool calls whose empty-assistant host was filtered out, they attach to the nearest prior kept assistant
• static/sessions.js: set S.toolCalls=[] instead of pre-filling from session-level tool_calls — this lets renderMessages() use its fallback derivation from per-message tool_calls (which already carry correct indices into the sanitized message array); the fix eliminates the "200+ tool cards all on the wrong message" symptom on context-compacted session load
• tests/test_issue401.py: 8 regression tests — 4 static structural checks and 4 behavioural Node.js tests covering index remapping, multiple consecutive empty assistants, no-filtering pass-through, and tool-role message exclusion

[v0.50.28] fix: expand openai-codex model catalog to match DEFAULT_CODEX_MODELS

_PROVIDER_MODELS["openai-codex"] only listed codex-mini-latest, so profiles using the openai-codex provider (e.g. a CodePath profile with default: gpt-5.4) showed only one entry in the model dropdown. Updated to mirror the agent's authoritative DEFAULT_CODEX_MODELS list: gpt-5.4, gpt-5.4-mini, gpt-5.3-codex, gpt-5.2-codex, gpt-5.1-codex-max, gpt-5.1-codex-mini, codex-mini-latest.

[v0.50.26] fix(sessions): redact sensitive titles in session list and search responses [SECURITY] (#400)

• api/routes.py: apply _redact_text() to session titles in all four response paths — /api/sessions merged list, /api/sessions/search empty-q, title-match, and content-match; use dict(s) copy before mutating to avoid corrupting the in-memory session cache
• tests/test_session_summary_redaction.py: 2 integration tests verifying sk- prefixed secrets in session titles are redacted from both list and search endpoint responses
• Original PR by @Hinotoi-agent (note: fix commit had a display artifact — sk- prefix was visually rendered as *** in terminal output but the actual bytes were correct and the token was recognized by the redaction engine)

[v0.50.25] Multi-PR batch: mobile scroll, import timestamps, profile security, mic fallback

fix: restore mobile chat scrolling and drawer close (#397)

• static/style.css: min-height:0 on .layout and .main (flex shrink chain fix); -webkit-overflow-scrolling:touch, touch-action:pan-y, overscroll-behavior-y:contain on .messages
• static/boot.js: call closeMobileSidebar() on new-conversation button and Ctrl+K shortcut so the transcript is visible immediately after starting a chat
• tests/test_mobile_layout.py: 41 new lines covering CSS fixes and both JS call sites
• Original PR by @Jordan-SkyLF

fix: preserve imported session timestamps (#395)

• api/models.py: Session.save(touch_updated_at=True) — new flag; import_cli_session() accepts created_at/updated_at kwargs and saves with touch_updated_at=False
• api/routes.py: extract created_at/updated_at from get_cli_sessions() metadata and forward to import; post-import save also uses touch_updated_at=False
• tests/test_gateway_sync.py: +53 lines — integration test verifying imported session keeps original timestamp and sorts correctly; also fix session file cleanup in test finally block
• Original PR by @Jordan-SkyLF

fix(profiles): block path traversal in profile switch and delete flows (#399) [SECURITY]

• api/profiles.py: new _resolve_named_profile_home(name) — validates name via ^[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() at HTTP handler level for both /api/profile/switch and /api/profile/delete
• tests/test_profile_path_security.py: 3 new tests — traversal rejected, valid name passes (cherry-picked from @Hinotoi-agent's PR, which was 62 commits behind master)

feat: add desktop microphone transcription fallback (#396)

• static/boot.js: detect _canRecordAudio; keep mic button enabled when MediaRecorder available even without SpeechRecognition; full MediaRecorder recording → /api/transcribe fallback path with proper cleanup and error handling

• api/upload.py: add transcribe_audio() helper — temp file, calls transcription_tools, always cleans up

• api/routes.py: add /api/transcribe POST handler — CSRF-protected, auth-gated, 20MB limit

• api/helpers.py: change Permissions-Policy microphone=() → microphone=(self) (required for getUserMedia)

• tests/test_voice_transcribe_endpoint.py: 87 new lines (3 tests with mocked transcription)

• tests/test_sprint19.py: regression guard for microphone Permissions-Policy

• tests/test_sprint20.py: 3 updated tests for new fallback capability checks

[v0.50.24] feat: opt-in chat bubble layout (closes #336)

• api/config.py: Add bubble_layout bool to _SETTINGS_DEFAULTS (default False) and _SETTINGS_BOOL_KEYS — new setting is opt-in, server-persisted, and coerced to bool on save
• static/style.css: 11 lines of CSS-only bubble layout — user rows align-self:flex-end / max-width 75%, assistant rows flex-start, all gated on body.bubble-layout class so the default full-width canvas is untouched; 700px responsive rule widens to 92%
• static/boot.js: Apply body.bubble-layout class from settings on page load; explicitly remove the class in the catch path so the feature stays off on API failure
• static/panels.js: Load checkbox state in loadSettingsPanel; write body.bubble_layout in saveSettings and immediately toggle body.bubble-layout class for live preview without a page reload
• static/index.html: Checkbox in the Appearance settings group, positioned between Show token usage and Show agent sessions
• static/i18n.js: English label + description keys; Spanish translations included in the same PR
• tests/test_issue336.py: 22 new tests covering config registration, JS class management in boot and panels, CSS selectors, HTML structure, i18n coverage for en+es, and API round-trip (default false, persist true/false, bool coercion)
• 1003 tests total (up from 981)

[v0.50.23] Add OpenCode Zen and Go provider support (fixes #362)

• api/config.py: Add opencode-zen and opencode-go to _PROVIDER_DISPLAY — providers now show human-readable names in the UI instead of raw IDs
• api/config.py: Add full model catalogs for both providers to _PROVIDER_MODELS — Zen (pay-as-you-go credits, 32 models) and Go (flat-rate $10/month, 7 models) now show the correct model list in the dropdown instead of falling through to the unknown-provider fallback
• api/config.py: Add OPENCODE_ZEN_API_KEY / OPENCODE_GO_API_KEY to the env-var fallback detection path — providers are correctly detected as authenticated when keys are set in .env
• tests/test_opencode_providers.py: 6 new tests covering display registration, model catalog registration, and env-var detection for both providers
• 985 tests total (up from 979)

[v0.50.22] Onboarding unblocked for reverse proxy / SSH tunnel deployments (fixes #390)

• api/routes.py: Onboarding setup endpoint now reads X-Forwarded-For and X-Real-IP headers before falling back to raw socket IP — reverse proxy (nginx/Caddy/Traefik) and SSH tunnel users are no longer incorrectly blocked
• Added HERMES_WEBUI_ONBOARDING_OPEN=1 env var escape hatch for operators on remote servers who control network access themselves
• Error message now includes the env var hint so users know how to unblock themselves
• 18 new tests covering all IP resolution paths (TestOnboardingIPLogic, TestOnboardingSetupEndpoint)

[v0.50.21] Live reasoning, tool progress, and in-flight session recovery (PR #367)

• Durable inflight reload recovery (static/ui.js, static/messages.js): saveInflightState / loadInflightState / clearInflightState backed by localStorage (hermes-webui-inflight-state key, per-session, 10-minute TTL). Snapshots are saved on every token, tool event, and tool completion, and cleared when the run ends/errors/cancels. On a full page reload with an active stream, loadSession() hydrates from the snapshot before calling attachLiveStream(..., {reconnecting:true}) — partial messages, live tool cards, and reasoning text all survive the reload.
• Live reasoning cards during streaming (static/ui.js, static/messages.js): The generic thinking spinner now upgrades to a live reasoning card when the backend streams reasoning text. _thinkingMarkup(text) and updateThinking(text) centralize the markup so the spinner and card share the same DOM slot. Works with models that emit reasoning via the agent's reasoning_callback or tool_progress_callback.
• tool_complete SSE events (api/streaming.py, static/messages.js): Tool progress callback now accepts the current agent signature on_tool(*cb_args, **cb_kwargs) — handles both the old 3-arg (name, preview, args) form and the new 4-arg (event_type, name, preview, args) form. tool.completed events transition live tool cards from running to done cleanly.
• In-flight session state stable across switches (static/messages.js, static/sessions.js): attachLiveStream refactored out of send() into a standalone function; partial assistant text mirrored into INFLIGHT state on every token; data-live-assistant DOM anchor preserved across renderMessages() calls so switching away and back doesn't lose or duplicate live output.
• Reload recovery (api/models.py, api/routes.py, api/streaming.py, static/sessions.js): active_stream_id, pending_user_message, pending_attachments, and pending_started_at now persisted on the session object before streaming starts and cleared on completion (or exception). /api/session returns these fields. After a page reload or session switch, loadSession() detects active_stream_id and calls attachLiveStream(..., {reconnecting:true}) to reattach to the live SSE stream.
• Session-scoped message queue (static/ui.js, static/messages.js): Global MSG_QUEUE replaced with SESSION_QUEUES keyed by session ID. Queued follow-up messages are associated with the session they were typed in and only drained when that session becomes idle — no cross-session bleed.
• newSession() idle reset (static/sessions.js): Sets S.busy=false, S.activeStreamId=null, clears the cancel button, resets composer status — ensures a fresh chat is immediately usable even if another session's stream is still running.
• Todos survive session reload (static/panels.js): loadTodos() now reads from S.session.messages (raw, includes tool-role messages) rather than S.messages (filtered display), so todo state reconstructed from tool outputs survives reloads.
  • 12 new regression tests in tests/test_regressions.py; 961 tests total (up from 949)

[v0.50.20] Silent error fix, stale model cleanup, live model fetching (fixes #373, #374, #375)

Fix: Chat no longer silently swallows agent failures (fixes #373)

• api/streaming.py: After run_conversation() completes, the server now checks whether the agent produced any assistant reply. If not (e.g., auth error swallowed internally, model unavailable, network timeout), it emits an apperror SSE event with a clear message and type (auth_mismatch or no_response) instead of silently emitting done. A _token_sent flag tracks whether any streaming tokens were sent.
• static/messages.js: The done handler has a belt-and-suspenders guard — if done arrives but no assistant message exists in the session (the apperror path should usually catch this first), an inline "No response received." message is shown. The apperror handler now also recognises the new no_response type with a distinct label.

Cleanup: Remove stale OpenAI models from default list (fixes #374)

• api/config.py: gpt-4o and o3 removed from _FALLBACK_MODELS and _PROVIDER_MODELS["openai"]. Both are superseded by newer models already in the list (gpt-5.4-mini for general use, o4-mini for reasoning). The Copilot provider list retains gpt-4o as it remains available via the Copilot API.

Feature: Live model fetching from provider API (closes #375)

• api/routes.py: New /api/models/live?provider=openai endpoint. Fetches the actual model list from the provider's /v1/models API using the user's configured credentials. Includes URL scheme validation (B310), SSRF guard (private IP block), and graceful not_supported response for providers without a standard /v1/models endpoint (Anthropic, Google). Response normalised to {id, label} list, filtered to chat models.
• static/ui.js: populateModelDropdown() now calls _fetchLiveModels() in the background after rendering the static list. Live models that aren't already in the dropdown are appended to the provider's optgroup. Results are cached per session so only one fetch per provider per page load. Skips Anthropic and Google (unsupported). Falls back to static list silently if the fetch fails.
  • 25 new tests in tests/test_issues_373_374_375.py; 949 tests total (up from 924)

[v0.50.19] Fix UnicodeEncodeError when downloading files with non-ASCII filenames (PR #378)

• Workspace file downloads no longer crash for Unicode filenames (api/routes.py): Clicking a PDF or other file with Chinese, Japanese, Arabic, or other non-ASCII characters in its name caused a UnicodeEncodeError because Python's HTTP server requires header values to be latin-1 encodable. A new _content_disposition_value(disposition, filename) helper centralises Content-Disposition generation: it strips CR/LF (injection guard), builds an ASCII fallback for the legacy filename= parameter (non-ASCII chars replaced with _), and preserves the full UTF-8 name in filename*=UTF-8''... per RFC 5987. Both attachment and inline responses use it.
  • 2 new integration tests in tests/test_sprint29.py covering Chinese filenames for both download and inline responses, verifying the header is latin-1 encodable and filename*=UTF-8'' is present; 924 tests total (up from 922)

[v0.50.18] Recover from invalid default workspace paths (PR #366)

• WebUI no longer breaks when the configured default workspace is unavailable (api/config.py): The workspace resolution path was refactored into three composable functions — _workspace_candidates(), _ensure_workspace_dir(), and resolve_default_workspace(). When the configured workspace (from env var, settings file, or passed path) cannot be created or accessed, the server falls back through an ordered priority list: HERMES_WEBUI_DEFAULT_WORKSPACE env var → ~/workspace (if exists) → ~/work (if exists) → ~/workspace (create it) → STATE_DIR/workspace.
• save_settings() now validates and corrects the workspace path (api/config.py): If a client posts an invalid or inaccessible default_workspace, the saved value is corrected to the nearest valid fallback rather than persisting an unusable path.
• Startup normalizes stale workspace paths (api/config.py): If the settings file stores a workspace that no longer exists, the server rewrites it with the resolved fallback on startup so the problem self-heals.
  • 7 tests in tests/test_default_workspace_fallback.py (2 from PR + 5 added during review: fallback creation, RuntimeError on all-fail, deduplication, env var priority, unwritable path returns False); 922 tests total (up from 915)

[v0.50.17] Docker: pre-install uv at build time + fix workspace permissions (fixes #357)

• Docker containers no longer need internet access at startup (Dockerfile): uv is now installed at image build time via RUN curl -LsSf https://astral.sh/uv/install.sh | env UV_INSTALL_DIR=/usr/local/bin sh (run as root, so uv lands in /usr/local/bin — accessible to all users). The init script skips the download if uv is already on PATH (command -v uv), and falls back to downloading with a proper error_exit if it isn't. This fixes startup failures in air-gapped, firewalled, or isolated Docker networks where github.com is unreachable at runtime.
  • Fix applied during review: the original PR installed uv as the hermeswebuitoo user (to ~hermeswebuitoo/.local/bin), which is not on the hermeswebui runtime user's PATH. Changed to install as root with UV_INSTALL_DIR=/usr/local/bin so uv is in the system PATH for all users.
• Workspace directory now writable by the hermeswebui user (docker_init.bash): The init script now uses sudo mkdir -p and sudo chown hermeswebui:hermeswebui for HERMES_WEBUI_DEFAULT_WORKSPACE. Docker auto-creates bind-mount directories as root if they don't exist on the host, making them unwritable by the app user. The sudo chown corrects ownership after creation.

[v0.50.16] Fix CSRF check failing behind reverse proxy on non-standard ports (PR #360)

• CSRF no longer rejects POST requests from reverse-proxied deployments on non-standard ports (api/routes.py, fixes #355): When serving behind Nginx Proxy Manager or similar on a port like :8000, browsers send Origin: https://app.example.com:8000 while the proxy forwards Host: app.example.com (port stripped). The old string comparison failed this as cross-origin. Two changes fix it:
  • _normalize_host_port(): properly splits host:port strings including IPv6 bracket notation ([::1]:8080)
  • _ports_match(scheme, origin_port, allowed_port): scheme-aware port equivalence — absent port equals :80 for http:// and :443 for https://. This prevents the previous cross-protocol confusion where http://host could incorrectly match an https://host:443 server (security fix applied on top of the original PR)
  • HERMES_WEBUI_ALLOWED_ORIGINS env var: comma-separated explicit origin allowlist for cases where port normalization alone isn't sufficient (e.g. non-standard ports like :8000 where the proxy strips the port entirely). Entries without a scheme (https://) are rejected with a startup warning.
• Security fix applied during review: the original _ports_match treated both port 80 and port 443 as interchangeable with "absent port", which is scheme-unaware. An http://host origin would pass for an https://host:443 server. Fixed by making the default-port lookup scheme-specific.
  • 29 new tests in tests/test_sprint29.py (5 from PR + 24 added during review): cover scheme-aware port matching, cross-protocol rejection, unit tests for _normalize_host_port and _ports_match, allowlist validation, comma-separated origins, no-scheme allowlist warning, the bug scenario with and without the allowlist; 900 tests total (up from 871)

[v0.50.15] KaTeX math rendering for LaTeX in chat and workspace previews (fixes #347)

• LaTeX / KaTeX math now renders in chat messages and workspace file previews (static/ui.js, static/workspace.js, static/style.css, static/index.html): Inline math ($...$, \(...\)) and display math ($$...$$, \[...\]) are rendered via KaTeX instead of displaying as raw text. Follows the existing mermaid lazy-load pattern: delimiters are stashed before markdown processing, placeholder elements are emitted, and KaTeX JS is loaded from CDN on first use — no KaTeX JS is loaded unless math is present.
  • $$...$$ and \[...\] → centered display math (<div class="katex-block">)
  • $...$ and \(...\) → inline math (<span class="katex-inline">); requires non-space at $ boundaries to avoid false positives on currency amounts like $5
  • KaTeX JS lazy-loaded from jsdelivr CDN with SRI hash; KaTeX CSS loaded eagerly in <head> to prevent layout shift
  • throwOnError:false — invalid LaTeX degrades to a <code> span rather than crashing the message
  • trust:false — disables KaTeX commands that could execute code
  • <span> added to SAFE_TAGS allowlist for inline math spans (tag name boundary check preserved)
• Fix: fence stash now runs before math stash (static/ui.js): The original PR had math stash before fence stash, meaning \$x$`` inside backtick code spans was incorrectly extracted as math instead of being protected as code. Order corrected — fence_stash runs first so code spans protect their contents.
• Workspace file previews now render math (static/workspace.js): Added requestAnimationFrame(renderKatexBlocks) after markdown file preview renders, matching the chat message path. Without this, math placeholders appeared in previews but were never rendered.
  • 29 tests in tests/test_issue347.py (18 original + 11 new covering stash ordering, workspace wiring, false-positive prevention); 870 tests total (up from 841)

[v0.50.14] Security fixes: B310 urlopen scheme validation, B324 MD5 usedforsecurity, B110 bare except logging + QuietHTTPServer (PR #354)

• B324 — MD5 no longer triggers crypto warnings (api/gateway_watcher.py): _snapshot_hash uses MD5 only as a non-cryptographic change-detection hash. Added usedforsecurity=False so systems with strict crypto policies (FIPS mode etc.) don't reject the call.
• B310 — urlopen now validates URL scheme (api/config.py, bootstrap.py): Both get_available_models() and wait_for_health() validate that the URL scheme is http or https before calling urllib.request.urlopen, preventing file:// or other dangerous scheme injection. Added # nosec B310 suppression after each validated call.
• B110 — bare except: pass blocks replaced with logger.debug() (12 files): All except Exception: pass and except: pass blocks now log the failure at DEBUG level so operators can diagnose issues in production without changing behavior. A module-level logger = logging.getLogger(__name__) was added to each file.
• QuietHTTPServer (server.py): Subclass of ThreadingHTTPServer that overrides handle_error() to silently drop ConnectionResetError, BrokenPipeError, ConnectionAbortedError, and socket errno 32/54/104 (client disconnect races). Real errors still delegate to the default handler. Reduces log spam from SSE clients that disconnect mid-stream.
• Session title redaction (api/routes.py): The /api/sessions list endpoint now applies _redact_text to session titles before returning them, consistent with the per-session redact_session_data() already applied elsewhere.
• Fix: QuietHTTPServer.handle_error uses sys.exc_info() (standard library) not traceback.sys.exc_info() (implementation detail); sys is now explicitly imported in server.py.
  • 19 new tests in tests/test_sprint43.py; 841 tests total (up from 822)

[v0.50.13] Fix session_search in WebUI sessions — inject SessionDB into AIAgent (PR #356)

• session_search now works in WebUI sessions (api/streaming.py): The agent's session_search tool returned "Session database not available" for all WebUI sessions. The CLI and gateway code paths both initialize a SessionDB instance and pass it via session_db= to AIAgent.__init__(), but the WebUI streaming path was missing this step. _run_agent_streaming now initializes SessionDB() before constructing the agent and passes it in. A try/except wrapper makes the init non-fatal — if hermes_state is unavailable (older installs, test environments), a WARNING is printed and session_db=None is passed instead, preserving the prior behavior gracefully.
  • 7 new tests in tests/test_sprint42.py; 822 tests total (up from 815)

[v0.50.12] Profile .env isolation — prevent API key leakage on profile switch (fixes #351)

• API keys no longer leak between profiles on switch (api/profiles.py): _reload_dotenv() now tracks which env vars were loaded from the active profile's .env and clears them before loading the next profile. Previously, switching from a profile with OPENAI_API_KEY=X to a profile without that key left X in os.environ for the duration of the process — effectively leaking credentials across the profile boundary. A module-level _loaded_profile_env_keys: set[str] tracks loaded keys; it is cleared and repopulated on every _reload_dotenv() call.
• apply_onboarding_setup() ordering fixed (api/onboarding.py): the belt-and-braces os.environ[key] = api_key direct assignment is now placed after _reload_dotenv(). Previously the key was wiped by the isolation cleanup when _reload_dotenv() ran immediately after the direct set.
  • 2 new tests in tests/test_profile_env_isolation.py; 815 tests total (up from 813)

[v0.50.11] Chat table styles + plain URL auto-linking (fixes #341, #342)

• Tables in chat messages now render with visible borders (static/style.css): The .msg-body area had no table CSS, so markdown tables sent by the assistant were unstyled and unreadable. Four new rules mirror the existing .preview-md table styles: border-collapse:collapse, per-cell padding and borders via var(--border2), and an alternating-row tint. Two :root[data-theme="light"] overrides ensure the borders and header background adapt correctly in light mode. (fixes #341)
• Plain URLs in chat messages are now clickable (static/ui.js): Bare URLs like https://example.com were rendered as plain text. A new autolink pass in renderMd() converts https?://... URLs to <a> tags automatically. Runs after the SAFE_TAGS escape pass (protecting code blocks), before paragraph wrapping. Also applied inside inlineMd() so URLs in list items, blockquotes, and table cells are linked too. Trailing punctuation stripped; esc() applied to both href and link text. (fixes #342)
  • 11 new tests (4 in tests/test_issue341.py, 7 in tests/test_issue342.py); 813 tests total (up from 802)
• Test infrastructure fix (tests/test_sprint34.py #349): two static-file opens used bare relative paths that failed when pytest ran from outside the repo root; replaced with pathlib.Path(__file__).parent.parent consistent with the rest of the suite. 813/813 now pass from any working directory.

[v0.50.10] Title auto-generation fix + mobile close button (PR #333)

• Session title now auto-generates for all default title values ('Untitled', 'New Chat', empty string): The condition in api/streaming.py that triggers title_from() previously only matched 'Untitled'. It now also covers 'New Chat' (used by some external clients/forks) and any empty/falsy title, so sessions started from those states get a proper auto-generated title after the first message.
• Redundant workspace panel close button hidden on mobile (static/style.css): On viewports ≤900px wide, both the desktop collapse button (#btnCollapseWorkspacePanel) and the mobile-specific X button (.mobile-close-btn) were rendered simultaneously. The desktop button is now hidden on mobile and .mobile-close-btn is hidden by default (desktop) and shown only on mobile — eliminating the duplicate control.
  • 11 new tests in tests/test_sprint41.py; 802 tests total (up from 791)

[v0.50.9] Onboarding works from Docker bridge networks (PR #335, fixes #334)

• Docker users can now complete onboarding without enabling auth first (closes #334): The onboarding setup endpoint previously only accepted requests from 127.0.0.1. Docker containers connect via bridge network IPs (172.17.x.x, etc.), so the endpoint returned a 403 mid-wizard with no clear explanation. The check now accepts any loopback or RFC-1918 private address (127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) using Python's ipaddress.is_loopback and is_private. Public IPs are still blocked unless auth is enabled.

[v0.50.8] Model dropdown deduplication — hyphen vs dot separator fix (PR #332)

• Model dropdown no longer shows duplicates for hyphen-format configs (e.g. claude-sonnet-4-6 from hermes-agent config): The server-side normalization in api/config.py now unifies hyphens and dots when checking whether the default model is already in the dropdown. Previously, claude-sonnet-4-6 (hermes-agent format) and claude-sonnet-4.6 (WebUI list format) were treated as different models, causing the same model to appear twice — once as a raw unlabelled entry and once with the correct display name. The raw entry is now suppressed and the labelled one is selected as default.
• README updated: test count corrected to 791 / 51 files; all module line counts updated to current values; onboarding.py, state_sync.py, updates.py added to the architecture listing.

[v0.50.7] OAuth provider onboarding path — Codex/Copilot no longer blocks setup (PR #331, fixes #329 bug 2)

• OAuth providers now have a proper onboarding path (closes bug 2): Users with openai-codex, copilot, qwen-oauth, or any other OAuth-authenticated provider now see a clear confirmation card instead of an unusable API key input form.
  • If already authenticated (chat_ready: true): blue "Provider already authenticated" card with a direct Continue button — no key entry required.
  • If not yet authenticated: amber card explaining how to run hermes auth or hermes model in a terminal to complete setup.
  • Either state includes a collapsible "switch provider" section for users who want to move to an API-key provider instead.
  • _build_setup_catalog now includes current_is_oauth boolean; fixed a latent KeyError crash when looking up default_model for OAuth providers.
  • 5 new i18n keys in English and Spanish (onboarding_oauth_*).
  • 15 new tests in tests/test_sprint40.py; 791 tests total (up from 776)

[v0.50.6] Skip-onboarding env var + synchronous API key reload (PR #330, fixes #329 bugs 1+3)

• HERMES_WEBUI_SKIP_ONBOARDING=1 (closes bug 1): Hosting providers can set this env var to bypass the first-run wizard entirely. Only takes effect when chat_ready is also true — a misconfigured deployment still shows the wizard. Accepts 1, true, or yes.
• API key takes effect immediately after onboarding (closes bug 3): apply_onboarding_setup now sets os.environ[env_var] synchronously after writing the key to .env, so the running process can use it without a server restart. Also attempts to reload hermes_cli's config cache as a belt-and-suspenders measure.
  • 8 new tests in tests/test_sprint39.py; 776 tests total (up from 768)

[v0.50.5] Think-tag stripping with leading whitespace (PR #327)

• Fix think-tag rendering for models that emit leading whitespace (e.g. MiniMax M2.7): Some models emit one or more newlines before the <think> opening tag. The previous regex used a ^ anchor, so it only matched when <think> was the very first character. When the anchor failed, the raw </think> tag appeared in the rendered message body.
  • static/ui.js (stored messages): removed ^ anchor from <think> and Gemma channel-token regexes; switched from .slice() to .replace() + .trimStart() so stripping works regardless of position
  • static/messages.js (live stream): trimStart() before startsWith/indexOf checks; partial-tag-prefix guard also uses trimmed buffer
  • 10 new tests in tests/test_sprint38.py; 768 tests total (up from 758)

[v0.50.3] Onboarding completes gracefully for pre-configured providers (PR #323, fixes #322)

• OAuth/CLI-configured providers no longer blocked by onboarding (closes #322): Users with providers already set up via the CLI (openai-codex, copilot, nous, etc.) hit Unsupported provider for WebUI onboarding when clicking "Open Hermes" on the finish page. The wizard now marks onboarding complete and lets them through — the agent setup is already done, no wizard steps needed.
  • 5 new tests in tests/test_sprint34.py; 758 tests total (up from 753)

[v0.50.2] Workspace panel state persists across refreshes

• Workspace panel open/closed persists (localStorage key hermes-webui-workspace-panel): Once you open the workspace/files pane, it stays open after a page refresh. Closing it explicitly saves the closed state, which also survives a refresh. The restore happens in the boot sequence before the first render, so there is no flash of the wrong state. Works for both desktop and mobile.
  • State is stored as 'open' or 'closed' — 'open' restores as 'browse' mode; any preview state is re-evaluated normally.
  • 7 new tests in tests/test_sprint37.py; 753 tests total (up from 746)

[v0.50.1] Mobile Enter key inserts newline (PR #315, fixes #269)

• Enter inserts newline on mobile (closes #269): On touch-primary devices (detected via matchMedia('(pointer:coarse)')), the Enter key now inserts a newline instead of sending. Users send via the Send button, which is always visible on mobile. Desktop behavior is unchanged — Enter sends, Shift+Enter inserts a newline.
  • The ctrl+enter setting continues to work as before on all devices.
  • Users who explicitly set send key to enter on mobile can override in Settings.
  • 4 new tests in tests/test_mobile_layout.py; 746 tests total (up from 742)

[v0.50.0] Composer-centric UI refresh + Hermes Control Center (PR #242)

Major UI overhaul by @aronprins — the biggest single contribution to the project. Rebased and reviewed on pr-242-review.

• Composer as control hub — model selector, profile chip, and workspace chip now live in the composer footer as pill buttons with dropdowns. The context window usage ring (token count, cost, fill) replaces the old linear pill.
• Hermes Control Center — a single sidebar launcher button (bottom of sidebar) replaces the gear icon settings modal. Tabbed 860px modal: Conversation tab (transcript/JSON export, import, clear), Preferences tab (all settings), System tab (version, password). Always resets to Conversation on close.
• Activity bar removed — turn-scoped status (thinking, cancelling) renders inline in the composer footer via setComposerStatus.
• Session ⋯ dropdown — per-row pin/archive/duplicate/move/delete actions move from inline buttons into a shared dropdown menu; click-outside/scroll/Escape handling.
• Workspace panel state machine — _workspacePanelMode (closed/browse/preview) in boot.js with proper transitions and discard-unsaved guard.
• Icon additions — save, chevron-right, arrow-right, pause, paperclip, copy, rotate-ccw, user added to icons.js.
• i18n additions — 6 new keys across en/de/zh/zh-Hant for control center sections.
• OLED theme — 7th built-in theme (true black background for OLED displays), originally contributed by @kevin-ho in PR #168.
• Mobile fixes — icon-only composer chips below 640px, overflow-y: hidden on .composer-left to prevent scrollbar, profile dropdown max-width: min(260px, calc(100vw - 32px)).
• 742 tests total; all existing tests pass; version badge in System tab updated to v0.50.0.

[v0.49.4] Cancel stream cleanup guaranteed (PR #309, fixes #299)

• Reliable cancel cleanup (closes #299): cancelStream() no longer depends on the SSE cancel event to clear busy state and status text. Previously, if the SSE connection was already closed when cancel fired, "Cancelling..." would linger indefinitely. Now cancelStream() clears S.activeStreamId, calls setBusy(false), setStatus(''), and hides the cancel button directly after the cancel API request — regardless of SSE connection state. The SSE cancel handler still runs when the connection is alive (all operations are idempotent).
  • 9 new tests in tests/test_sprint36.py; 742 tests total (up from 733)

[v0.49.3] Session title guard + breadcrumb nav + wider panel (PRs #301, #302)

• Preserve user-renamed session titles (PR #301 by @franksong2702 / closes #300): title_from() now only runs when the session title is still 'Untitled'. Previously it overwrote user-assigned titles on every conversation turn.
  • Fixed in both api/streaming.py (streaming path) and api/routes.py (sync path).
• Clickable breadcrumb navigation (PR #302 by @franksong2702 / closes #292): Workspace file preview now shows a clickable breadcrumb path bar. Each segment navigates directly to that directory level. Paths with spaces and special characters handled correctly. clearPreview() restores the directory breadcrumb on close.
• Wider right panel (PR #302): PANEL_MAX raised from 500 to 1200 — right panel can now be dragged wider on ultrawide screens.
• Responsive message width (PR #302): .messages-inner now scales up gracefully at 1400px (1100px max) and 1800px (1200px max) viewport widths instead of capping at 800px on all screen sizes.
  • 12 new tests in tests/test_sprint35.py; 733 tests total (up from 721)

[v0.49.2] OAuth provider support in onboarding (issues #303, #304)

• OAuth provider bypass (closes #303, #304): The first-run onboarding wizard now correctly recognizes OAuth-authenticated providers (GitHub Copilot, OpenAI Codex, Nous Portal, Qwen OAuth) as ready, instead of always demanding an API key.
  • New _provider_oauth_authenticated() helper in api/onboarding.py checks hermes_cli.auth.get_auth_status() first (authoritative), then falls back to parsing ~/.hermes/auth.json directly for the known OAuth provider IDs (openai-codex, copilot, copilot-acp, qwen-oauth, nous).
  • _status_from_runtime() now has an else branch for providers not in _SUPPORTED_PROVIDER_SETUPS; OAuth-authenticated providers return provider_ready=True and setup_state="ready".
  • The provider_incomplete status note no longer says "API key" for OAuth providers — it now says "Run 'hermes auth' or 'hermes model' in a terminal to complete setup."
  • 21 new tests in tests/test_sprint34.py; 721 tests total (up from 700)

[v0.49.1] Docker docs + mobile Profiles button (PRs #291, #265)

• Two-container Docker setup (PR #291 / closes #288): New docker-compose.two-container.yml for running the Hermes Agent and WebUI as separate containers with shared volumes. Documents the architecture clearly; localhost-only port binding by default.
• Mobile Profiles button (PR #265 by @Bobby9228): Adds Profiles to the mobile bottom navigation bar (last position: Chat → Tasks → Skills → Memory → Spaces → Profiles). Uses mobileSwitchPanel() for correct active-highlight behaviour; data-panel="profiles" attribute set; SVG matches other nav icons; 3 new tests.
  • 700 tests total (up from 697)

[v0.49.0] First-run onboarding wizard + self-update hardening (PRs #285, #287, #289)

• One-shot bootstrap and first-run setup wizard (PR #285 — first-run onboarding flow): New users are greeted with a guided onboarding overlay on first load. The wizard checks system status, configures a provider (OpenRouter, Anthropic, OpenAI, or custom OpenAI-compatible endpoint), sets a workspace and optional password, and marks setup as complete — all without leaving the browser.

  • bootstrap.py: one-shot CLI bootstrap that writes ~/.hermes/config.yaml and ~/.hermes/.env from flags; idempotent and safe to re-run
  • api/routes.py: /api/onboarding/status (GET) and /api/onboarding/complete (POST) endpoints; real provider config persistence to config.yaml + .env
  • static/onboarding.js: full wizard JS module — step navigation, provider dropdown, model selector, API key input, Back/Continue flow, i18n support
  • static/index.html: onboarding overlay HTML shell + <script src="/static/onboarding.js"> load
  • static/i18n.js: 40+ onboarding keys added to all 5 locales (en, es, de, zh-Hans, zh-Hant)
  • static/boot.js: on load, fetches /api/onboarding/status and opens wizard when completed=false
  • Wizard does NOT show when onboarding_completed=true in settings
  • 14 new tests in tests/test_onboarding.py; 693 tests total (up from 679)

• Self-update git pull diagnostics (PR #287): Fixes multiple failure modes in the WebUI self-update flow when the repo has a non-trivial git state.

  • _run_git() now returns stderr on failure (stdout fallback, then exit-code message) — users see actionable git errors instead of empty strings
  • New _split_remote_ref() helper splits origin/master into ('origin', 'master') before git pull --ff-only — fixes silent failures where git misinterpreted the combined string as a repository name
  • --untracked-files=no added to git status --porcelain — prevents spurious stash failures in repos with untracked files
  • Early merge-conflict detection via porcelain status codes before attempting pull
  • 4 new unit tests in tests/test_updates.py

• Skip flaky redaction test in agent-less environments (PR #289): test_api_sessions_list_redacts_titles added to the CI skip list for environments without hermes-agent installed. Test still runs with the full agent; security coverage preserved by 6 pure-unit tests and 2 other API-level redaction tests.

  • 697 tests total (up from 693)

[v0.48.2] Provider/model mismatch warning (PR #283, fixes #266)

• Provider mismatch warning (PR #283): WebUI now warns when you select a model from a provider different from the one Hermes is configured for, instead of silently failing with a 401 error.
  • api/streaming.py: 401/auth errors classified as type='auth_mismatch' with an actionable hint ("Run hermes model in your terminal to switch providers")
  • static/ui.js: populateModelDropdown() stores active_provider from /api/models as window._activeProvider; new _checkProviderMismatch() helper compares selected model's provider prefix against the configured provider
  • static/boot.js: modelSelect.onchange calls _checkProviderMismatch() and shows a toast warning immediately on selection
  • static/messages.js: apperror handler shows "Provider mismatch" label (via i18n) instead of "Error" for auth errors
  • static/i18n.js: provider_mismatch_warning and provider_mismatch_label keys added to all 5 locales (en, es, de, zh-Hans, zh-Hant)
  • Check skipped for openrouter and custom providers to avoid false positives
  • 21 new tests in tests/test_provider_mismatch.py; 679 tests total (up from 658)

[v0.48.1] Markdown table inline formatting (PR #278)

• Inline formatting in table cells (PR #278, @nesquena): Table header and data cells now render **bold**, *italic*, `code`, and [links](url) correctly. Previously esc() was used, which displayed raw HTML tags as text. Changed to inlineMd() consistent with list items and blockquotes. XSS-safe: inlineMd() escapes all interpolated values. Two-line change in static/ui.js. Fixes #273.

[v0.48.0] Real-time gateway session sync (PR #274)

• Real-time gateway session sync (PR #274, @bergeouss): Gateway sessions from Telegram, Discord, Slack, and other messaging platforms now appear in the WebUI sidebar and update in real time as new messages arrive. Enable via the "Show agent sessions" checkbox (renamed from "Show CLI sessions").
  • api/gateway_watcher.py: background daemon thread polling state.db every 5s using MD5 hash-based change detection
  • New SSE endpoint /api/sessions/gateway/stream for real-time push to browser
  • Dynamic source badges: telegram (blue), discord (purple), slack (dark purple), cli (green)
  • Zero changes to hermes-agent — WebUI reads the shared state.db that both components access
  • 10 new tests in test_gateway_sync.py covering metadata, filtering, SSE, and watcher lifecycle
  • 658 tests (up from 648)

[v0.47.1] Spanish locale (PR #275)

• Spanish (es) locale (PR #275, @gabogabucho): Full Spanish translation for all 175 UI strings. Exposed automatically in the language selector via existing LOCALES wiring. Includes regression tests verifying locale presence, representative translations, and key-parity with English. 648 tests (up from 645).

[v0.47.0] — 2026-04-11

Features

• /skills [query] slash command (PR #257): Fetches from /api/skills, groups results by category (alphabetically), renders as a formatted assistant message. Optional query filters by name, description, or category. Shows in the / autocomplete dropdown. i18n for en/de/zh/zh-Hant. 1 regression test added.
• Shared app dialogs replace native confirm()/prompt() (PR #251, extracted from #242 by @aronprins): showConfirmDialog() and showPromptDialog() in ui.js, backed by #appDialogOverlay. Replaces all 11 native browser dialog call sites across panels.js, sessions.js, ui.js, workspace.js. Full keyboard focus trap (Tab/Escape/Enter), ARIA roles, danger mode, focus restore, mobile-responsive buttons. i18n for en/de/zh/zh-Hant. 5 new tests in test_sprint33.py.
• Session ⋯ action dropdown (PR #252, extracted from #242 by @aronprins): Replaces 5 per-row hover buttons (pin/move/archive/duplicate/delete) with a single ⋯ trigger. Menu uses position:fixed to avoid sidebar clipping. Full close handling: click-outside, scroll, Escape, resize-reposition. test_sprint16.py updated to assert the new trigger exists and old button classes are gone.

Bug Fixes

• Custom provider with slash model name no longer rerouted to OpenRouter (PR #255): resolve_model_provider() now returns immediately with the configured provider/base_url when base_url is set, before the slash-based OpenRouter heuristic runs. Fixes google/gemma-4-26b-a4b with provider: custom being silently routed to OpenRouter (401 errors). 1 regression test added. Fixes #230.
• Android Chrome: workspace panel now closeable on mobile (PR #256): toggleMobileFiles() now shows/hides the mobile overlay. New closeMobileFiles() helper closes the right panel with correct overlay tracking. Overlay tap-to-close calls both closeMobileSidebar() and closeMobileFiles(). Mobile-only × close button added to workspace panel header. Fix applied during review: closeMobileSidebar() now checks if the right panel is still open before hiding the overlay. Fixes #247.
• Android Chrome: profile dropdown no longer clipped on mobile (PR #256): .profile-dropdown switches to position:fixed; top:56px; right:8px at max-width:900px, escaping the overflow-x:auto stacking context that was making it invisible. Fixes #246.

Tests

• Mobile layout regression suite (PR #254): 14 static tests in tests/test_mobile_layout.py that run on every QA pass. Covers: CSS breakpoints at 900px/640px, right panel slide-over, mobile overlay, bottom nav, files button, profile dropdown z-index, chip overflow, workspace close, 100dvh, 44px touch targets, 16px textarea font. All pass against current and future master.

CSS hotfix (commit a2ae953, post-tag): session action menu — icon now displays inline-left of text. The .ws-opt base class (flex-direction:column) was causing SVG icons to stack above the label. Fixed with 3 CSS rule overrides on .session-action-opt.

[v0.46.0] — 2026-04-11

Features

• Docker UID/GID matching (PR #237 by @mmartial): New docker_init.bash entrypoint adds hermeswebui/hermeswebuitoo user pattern so container-created files match the host user UID/GID. Prevents .hermes volume mounts from being owned by root. Configure via WANTED_UID and WANTED_GID env vars (default 1000/1000). README updated with setup instructions.
  • Dockerfile — two-user pattern with passwordless sudo; /.within_container marker for in-container detection; starts as hermeswebuitoo, switches to correct UID/GID
  • docker-compose.yml — mounts .hermes at /home/hermeswebui/.hermes; uses ${UID:-1000}/${GID:-1000} for UID/GID passthrough
  • server.py — detects /.within_container and prints a note when binding to 0.0.0.0

Security

• Credential redaction in API responses (PR #243 by @kcclaw001): All API endpoints now redact credentials from responses at the response layer. Session files on disk are unchanged; only the API output is masked.
  • api/helpers.py — redact_session_data() and _redact_value() apply pattern-based redaction to messages, tool_calls, and title; covers GitHub PATs, OpenAI/Anthropic keys, AWS keys, Slack tokens, HuggingFace tokens, Authorization Bearer headers, and PEM private key blocks
  • api/routes.py — GET /api/session, GET /api/session/export, GET /api/memory all wrapped with redaction
  • api/streaming.py — SSE done event payload redacted before broadcast
  • api/startup.py — new fix_credential_permissions() called at startup; chmod 600 on .env, google_token.json, auth.json, .signing_key if they have group/other read bits set
  • tests/test_security_redaction.py — 13 new tests covering redaction functions and endpoint structural verification

Bug Fixes

• Custom model list discovery with config API key (PR #238 by @ccqqlo): get_available_models() now reads api_key from config.yaml before env vars when fetching /v1/models from custom endpoints (LM Studio, Ollama, etc.). Priority: model.api_key → providers.<active>.api_key → providers.custom.api_key → env vars. Also adds OpenAI/Python 1.0 User-Agent header. Fixes model picker collapsing to single default model for config-only setups. 1 new regression test.
• HTML entity decode before markdown processing (PR #239 by @Argonaut790): Adds decode() helper in renderMd() to fix double-escaping of HTML entities from LLM output (e.g. <code> becoming <code> instead of rendering). XSS-safe: decode runs before esc(), only 5 entity patterns (<, >, &, ", ').
• Simplified Chinese translations completed (PR #239 by @Argonaut790): 40+ missing keys added to zh locale (123 → 164 keys). New zh-Hant (Traditional Chinese) locale with 163 keys.
• Cancel button now interrupts agent execution (PR #244 by @huangzt): cancel_stream() now calls agent.interrupt() to stop backend tool execution, not just the SSE stream. AGENT_INSTANCES dict (protected by STREAMS_LOCK) tracks active agents. Race condition fixed: after storing agent, immediately checks if cancel was already requested. Frontend: removes stale "Cancelling..." status text; setBusy(false) always called on cancel. 6 new unit tests in tests/test_cancel_interrupt.py.

624 tests (up from 604 on v0.45.0 — +20 new tests)

[v0.45.0] — 2026-04-10

Features

• Custom endpoint fields in new profile form (PR #233, fixes #170): The New Profile form now accepts optional Base URL and API key fields. When provided, both are written into the new profile's config.yaml under the model section, enabling local-endpoint setups (Ollama, LMStudio, etc.) to be configured in one step without editing YAML manually. The write is a no-op when both fields are left blank, so existing profile creation behavior is unchanged.
  • api/profiles.py — _write_endpoint_to_config() merges base_url/api_key into config.yaml using yaml.safe_load + yaml.dump, preserving any existing keys
  • api/routes.py — accepts base_url and api_key from POST body; validates that base_url, if provided, starts with http:// or https:// (returns 400 for invalid schemes)
  • static/index.html — two new inputs added to the New Profile form: Base URL (with http://localhost:11434 placeholder) and API key (password type)
  • static/panels.js — submitProfileCreate() reads both fields, validates URL format client-side before sending, and includes them in the create payload; toggleProfileForm() clears them on cancel
  • 9 tests in tests/test_sprint31.py covering: config write (base_url, api_key, both, merge, no-op), route acceptance, profile path in response, and invalid-scheme rejection

604 tests (up from 595)

[v0.44.1] — 2026-04-10

• Unskip 16 approval tests (PR #231): test_approval_unblock.py was importing has_pending and pop_pending from tools.approval, which the agent module had removed. The import failure tripped the APPROVAL_AVAILABLE guard and skipped all 16 tests in the file. Neither symbol was used in any test body. Removing the stale imports restores 595/595 passing, 0 skipped.

[v0.44.0] — 2026-04-10

Features

• Lucide SVG icons (PR #221): Replaces all emoji icons in the sidebar, workspace, and tool cards with self-hosted Lucide SVG paths via static/icons.js. No CDN dependency — icons are bundled directly. The li(name) renderer uses a hardcoded whitelist, so server-supplied tool names never inject arbitrary SVG. All 35 onclick= functions verified to exist in JS; all 21 icon references verified in icons.js.

Bug Fixes

• Approval card hides immediately on respond/stream-end (PR #225): respondApproval() and all stream-end SSE handlers (done, cancel, apperror, error, start-error) now call hideApprovalCard(true). Previously the 30s minimum-visibility guard deferred the hide, leaving the card visible with disabled buttons for up to 30s after the user clicked Approve/Deny or the session completed. The poll-loop tick correctly keeps no-force so the guard still protects against transient polling gaps. Adds 11 structural tests for the timer logic.
• Login page CSP fix (PR #226): Moves doLogin() and Enter key listener from inline <script>/onsubmit/onkeydown attributes into static/login.js. Inline handlers are blocked by strict script-src CSP, causing silent login failure. i18n error strings now passed via data-* attributes instead of injected JS literals. Also guards res.json() parse with try/catch so non-JSON server errors fall back to the password-error message. Fixes #222.
• Update error messages (PR #227): _apply_update_inner() now fetches before pulling and surfaces three distinct failure modes with actionable recovery commands: network unreachable, diverged history (git reset --hard), and missing upstream tracking branch (git branch --set-upstream-to). Generic fallback truncates to 300 chars with a sentinel for empty output. Adds 13 tests covering all new diagnostic code paths. Fixes #223.
• Approval pending check (PR #228): GET /api/approval/pending always returned {pending: null} after the agent module renamed has_pending to has_blocking_approval. The route now checks _pending directly under _lock, matching how submit_pending writes to it. Fixes test_approval_submit_and_respond.

Tests

• 579 passing, 16 skipped at this tag (595/595 after v0.44.1 unskip — +24 new tests across PRs #225, #227, #228)

[v0.43.1] — 2026-04-10

• CSRF fix for reverse proxies (PR #219): The CSRF check now accepts X-Forwarded-Host and X-Real-Host headers in addition to Host, so deployments behind Caddy, nginx, and Traefik no longer reject POST requests with "Cross-origin request rejected". Security is preserved — requests with no matching proxy header are still rejected. Fixes #218.

[v0.43.0] — 2026-04-10

Features

• Auto-install agent dependencies on startup (PRs #215 + #216): When hermes-agent is found on disk but its Python dependencies are missing (common in Docker deployments where the agent is volume-mounted post-build), server.py now calls api/startup.auto_install_agent_deps() to install from requirements.txt or pyproject.toml. Falls back gracefully — failures are logged and never fatal.

Bug Fixes

• Session ID validator broadened (PR #212): Session.load() rejected any session ID containing non-hex characters, breaking sessions created by the new hermes-agent format (YYYYMMDD_HHMMSS_xxxxxx). Validator now accepts [0-9a-z_] while rejecting path traversal patterns (null bytes, slashes, backslashes, dot-extensions).
• Test suite isolation (PR #216): conftest.py now kills any stale process on the test port (8788) before starting the fixture server. Stale QA harness servers (8792/8793) could occupy 8788 and cause non-deterministic test failures across the full suite.

[v0.42.2] — 2026-04-10

Bug Fixes

• CSP blocking inline event handlers (PR #209): script-src 'self' blocked all 55+ inline onclick= handlers in index.html, making the settings panel, sidebar navigation, and most interactive controls non-functional. Added 'unsafe-inline' to script-src. Also restores https://cdn.jsdelivr.net to script-src and style-src for Mermaid.js and Prism.js (dropped in v0.42.1).

[v0.42.1] — 2026-04-11

Bug Fixes

• i18n button text stripping (post-review): Three sidebar buttons (+ New job, + New skill, + New profile) and three suggestion buttons had data-i18n on the outer element, which caused applyLocaleToDOM to replace the entire textContent — stripping the + prefix and emoji characters on locale switch. Fixed by wrapping only the translatable label text in a <span data-i18n="...">.
• German translation corrections (post-review): Fixed cancelling (imperative → progressive "Wird abgebrochen…"), editing (first-person verb → noun "Bearbeitung"), and completed truncated descriptions for empty_subtitle, settings_desc_check_updates, and settings_desc_cli_sessions.

[v0.42.0] — 2026-04-10

Features

• German translation (PR #190 by @DavidSchuchert): Complete de locale covering all UI strings — settings, commands, sidebar, approval cards. Also extends the i18n system with data-i18n-title and data-i18n-placeholder attribute support so tooltip text and input placeholders are now translatable. German speech recognition uses de-DE.

Bug Fixes

• Custom slash-model routing (PR #189 by @smurmann): Model IDs like google/gemma-4-26b-a4b from custom providers (LM Studio, Ollama) were silently misrouted to OpenRouter because of the slash-heuristic. Custom providers now win: entries in config.yaml → custom_providers are checked first, so their model IDs route to the correct local endpoint regardless of format.
• Phantom Custom group in model picker (PR #191 by @mbac): When model.provider was a named provider (e.g. openai-codex) and model.base_url was set, hermes_cli reported 'custom' as authenticated, producing a duplicate "Custom" group in the dropdown. The real provider's group was missing the configured default model. Fixed by discarding the phantom custom entry when a real named provider is active.
• Hyphen/space model group injection (PR #191): The "ensure default_model appears" post-pass used active_provider.lower() in group_name.lower(), which fails for openai-codex vs display name OpenAI Codex (hyphen vs space). Now uses _PROVIDER_DISPLAY for exact display-name matching.

[v0.41.0] — 2026-04-10

Features

• Optional HTTPS/TLS support (PR #199): Set HERMES_WEBUI_TLS_CERT and HERMES_WEBUI_TLS_KEY env vars to enable HTTPS natively. Uses ssl.PROTOCOL_TLS_SERVER with TLS 1.2 minimum. Gracefully falls back to HTTP if cert loading fails. No reverse proxy required for LAN/VPN deployments.

Bug Fixes

• CSP blocking Mermaid and Prism (PR #197): Added Content-Security-Policy and Permissions-Policy headers to every response. CSP allows cdn.jsdelivr.net in script-src and style-src for Mermaid.js (dynamically loaded) and Prism.js (statically loaded with SRI integrity hashes). All other external origins blocked.
• Session memory leak (PR #196): api/auth.py accumulated expired session tokens indefinitely. Added _prune_expired_sessions() called lazily on every verify_session() call. No background thread, no lock contention.
• Slow-client thread exhaustion (PR #198): Added Handler.timeout = 30 to kill idle/stalled connections before they exhaust the thread pool.
• False update alerts on feature branches (PR #201): Update checker compared HEAD..origin/master even when on a feature branch, counting unrelated master commits as missing updates. Now uses git rev-parse --abbrev-ref @{upstream} to track the current branch's upstream. Falls back to default branch when no upstream is set.
• CLI session file browser returning 404 (PR #204): /api/list only checked the WebUI in-memory session dict, so CLI sessions shown in the sidebar always returned 404 for file browsing. Now falls back to get_cli_sessions() — the same pattern used by /api/session GET and /api/sessions list.

[v0.40.2] — 2026-04-09

Features

• Full approval UI (PR #187): When the agent triggers a dangerous command (e.g. rm -rf, pkill -9), a polished approval card now appears immediately instead of leaving the chat stuck in "Thinking…" forever. Four one-click buttons: Allow once, Allow session, Always allow, Deny. Enter key defaults to Allow once. Buttons disable immediately on click to prevent double-submit. Card auto-focuses Allow once so keyboard-only users can approve in one keystroke. All labels and the heading are fully i18n-translated (English + Chinese).

Bug Fixes

• Approval SSE event never sent (PR #187): register_gateway_notify() was never called before the agent ran, so the approval module had no way to push the approval SSE event to the frontend. Fixed by registering a callback that calls put('approval', ...) the instant a dangerous command is detected.
• Agent thread never unblocked (PR #187): /api/approval/respond did not call resolve_gateway_approval(), so the agent thread waited for the full 5-minute gateway timeout. Now calls it on every respond, waking the thread immediately.
• _unreg_notify scoping (PR #187): Variable was only assigned inside a try block but referenced in finally. Initialised to None before the try so the finally guard is always well-defined.

Tests

• 32 new tests in tests/test_sprint30.py: approval card HTML structure, all 4 button IDs and data-i18n labels, keyboard shortcut in boot.js, i18n keys in both locales, CSS loading/disabled/kbd states, messages.js button-disable behaviour, streaming.py scoping, HTTP regression for all 4 choices.
• 16 tests in tests/test_approval_unblock.py (gateway approval unit + HTTP).
• 547 tests total (499 → 515 → 547).

---

[v0.40.1] — 2026-04-09

Bug Fixes

• Default locale on first install (PR #185): A fresh install would start in English based on the server default, but loadLocale() could resurrect a stale or unsupported locale code from localStorage. Now loadLocale() falls back to English when there is no saved code or the saved code is not in the LOCALES bundle. setLocale() also stores the resolved code, so an unknown input never persists to storage.

---

[v0.40.0] — 2026-04-09

Features

• i18n — pluggable language switcher (PR #179): Settings panel now has a Language dropdown. Ships with English and Chinese (中文). All UI strings use a t() helper that falls back to English for missing keys. The login page also localises — title, placeholder, button, and error strings all respond to the saved locale. Add a language by adding a LOCALES entry to static/i18n.js.
• Notification sound + browser notifications (PR #180): Two new settings toggles. "Notification sound" plays a short two-tone chime when the assistant finishes or an approval card appears. "Browser notification" fires a system notification when the tab is in the background.
• Thinking / reasoning block display (PR #181, #182): Inline <think>…</think> and Gemma 4 <|channel>thought…<channel|> tags are parsed out of assistant messages and rendered as a collapsible lightbulb "Thinking" card above the reply. During streaming, the bubble shows "Thinking…" until the tag closes. Hardened against partial-tag edge cases and empty thinking blocks.

Bug Fixes

• Stray } in message row HTML (PR #183): A typo in the i18n refactor left an extra } in the msg-role div template literal, producing <div class="msg-role user" }>. Removed.
• JS-escape login locale strings (PR #183): LOGIN_INVALID_PW and LOGIN_CONN_FAILED were injected into a JS string context without escaping single quotes or backslashes. Now uses minimal JS-string escaping.

[v0.39.1] — 2026-04-08

Bug Fixes

• _ENV_LOCK deadlock resolved. The environment variable lock was held for the entire duration of agent execution (including all tool calls and streaming), blocking all concurrent requests. Now the lock is acquired only for the brief env variable read/write operations, released before the agent runs, and re-acquired in the finally block for restoration.

---

[v0.39.0] — 2026-04-08

Security (12 fixes — PR #171 by @betamod, reviewed by @nesquena-hermes)

• CSRF protection: all POST endpoints now validate Origin/Referer against Host. Non-browser clients (curl, agent) without these headers are unaffected.
• PBKDF2 password hashing: save_settings() was using single-iteration SHA-256. Now calls auth._hash_password() — PBKDF2-HMAC-SHA256 with 600,000 iterations and a per-installation random salt.
• Login rate limiting: 5 failed attempts per 60 seconds per IP returns HTTP 429.
• Session ID validation: Session.load() rejects any non-hex character before touching the filesystem, preventing path traversal via crafted session IDs.
• SSRF DNS resolution: get_available_models() resolves DNS before checking private IPs. Prevents DNS rebinding attacks. Known-local providers (Ollama, LM Studio, localhost) are whitelisted.
• Non-loopback startup warning: server prints a clear warning when binding to 0.0.0.0 without a password set — a common Docker footgun.
• ENV_LOCK consistency: _ENV_LOCK now wraps all os.environ mutations in both the sync chat and streaming restore blocks, preventing races across concurrent requests.
• Stored XSS prevention: files with text/html, application/xhtml+xml, or image/svg+xml MIME types are forced to Content-Disposition: attachment, preventing execution in-browser.
• HMAC signature: extended from 64 bits to 128 bits (16-char to 32-char hex).
• Skills path validation: resolve().relative_to(SKILLS_DIR) check added after skill directory construction to prevent traversal.
• Secure cookie flag: auto-set when TLS or X-Forwarded-Proto: https is detected. Uses getattr safely so plain sockets don't raise AttributeError.
• Error path sanitization: _sanitize_error() strips absolute filesystem paths from exception messages before they reach the client.

Tests

• Added tests/test_sprint29.py — 33 tests covering all 12 security fixes.

---

[v0.38.6] — 2026-04-07

Fixed

• /insights message count always 0 for WebUI sessions (#163, #164): sync_session_usage() wrote token counts, cost, model, and title to state.db but never message_count. Both the streaming and sync chat paths now pass len(s.messages). Note: /insights sync is opt-in — enable Sync to Insights in Settings (it's off by default).

---

[v0.38.5] — 2026-04-06

Fixed

• Custom endpoint URL construction (#138, #160): base_url ending in /v1 was incorrectly stripped before appending /models, producing http://host/models instead of http://host/v1/models. Fixed to append directly.
• custom_providers config entries now appear in dropdown (#138, #160): Models defined under config.yaml custom_providers (e.g. Ollama aliases, Azure model overrides) are now always included in the dropdown, even when the /v1/models endpoint is unreachable.
• Custom endpoint API key reads profile .env (#138, #160): Custom endpoint auth now checks ~/.hermes/.env keys in addition to os.environ.

---

[v0.38.4] — 2026-04-06

Fixed

• Copilot false positive in model dropdown (#158): list_available_providers() reported Copilot as available on any machine with gh CLI auth, because the Copilot token resolver falls back to gh auth token. The dropdown now skips any provider whose credential source is 'gh auth token' — only explicit, dedicated credentials count. Users with GITHUB_TOKEN explicitly set in their .env still see Copilot correctly.

---

[v0.38.3] — 2026-04-06

Fixed

• Model dropdown shows only configured providers (#155): Provider detection now uses hermes_cli.models.list_available_providers() — the same auth check the Hermes agent uses at runtime — instead of scanning raw API key env vars. The dropdown now reflects exactly what the user has configured (auth.json, credential pools, OAuth flows like Copilot). When no providers are detected, shows only the configured default model rather than a full generic list. Added copilot and gemini to the curated model lists. Falls back to env var scanning for standalone installs without hermes-agent.

---

[v0.38.2] — 2026-04-06

Fixed

• Tool cards actually render on page reload (#140, #153): PR #149 fixed the wrong filter — it updated vis but not visWithIdx (the loop that actually creates DOM rows), so anchor rows were never inserted. This PR fixes visWithIdx. Additionally, streaming.py's assistant_msg_idx builder previously only scanned Anthropic content-array format and produced idx=-1 for all OpenAI-format tool calls (the format used in saved sessions); it now handles both. As a final fallback, renderMessages() now builds tool card data directly from per-message tool_calls arrays when S.toolCalls is empty, covering historical sessions that predate session-level tool tracking.

---

[v0.38.1] — 2026-04-06

Fixed

• Model selector duplicates (#147, #151): When config.yaml sets model.default with a provider prefix (e.g. anthropic/claude-opus-4.6), the model dropdown no longer shows a duplicate entry alongside the existing bare-ID entry. The dedup check now normalizes both sides before comparing.
• Stale model labels (#147, #151): Sessions created with models no longer in the current provider list now show "ModelName (unavailable)" in muted text with a tooltip, instead of appearing as a normal selectable option that would fail silently on send.

---

[v0.38.0] — 2026-04-06

Fixed

• Multi-provider model routing (#138): Non-default provider models now use @provider:model format. resolve_model_provider() routes them through resolve_runtime_provider(requested=provider) — no OpenRouter fallback for users with direct provider keys.
• Personalities from config.yaml (#139): /api/personalities reads from config.yaml agent.personalities (the documented mechanism). Personality prompts pass via agent.ephemeral_system_prompt.
• Tool call cards survive page reload (#140): Assistant messages with only tool_use content are no longer filtered from the render list, preserving anchor rows for tool card display.

---

[v0.37.0] /personality command, model prefix routing fix, tool card reload fix

April 6, 2026 | 465 tests

Features

• /personality slash command. Set a per-session agent personality from ~/.hermes/personalities/<name>/SOUL.md. The personality prompt is prepended to the system message for every turn. Use /personality <name> to activate, /personality none to clear, /personality (no args) to list available personalities. Backend: GET /api/personalities, POST /api/personality/set. (PR #143)

Bug Fixes

• Model dropdown routes non-default provider models correctly (#138). When the active provider is anthropic and you pick a minimax model, its ID is now prefixed minimax/MiniMax-M2.7 so resolve_model_provider() can route it through OpenRouter. Guards added: active_provider=None prevents all-providers-prefixed, case is normalised, shared _PROVIDER_MODELS list is no longer mutated by the default_model injector. (PR #142)
• Tool call cards persist correctly after page reload. The reload rendering logic now anchors cards AFTER the triggering assistant row (not before the next one), handles multi-step chains sharing a filtered anchor in chronological order, and filters fallback anchor to assistant rows only. (PR #141)

---

[v0.36.3] Configurable Assistant Name

April 6, 2026 | 449 tests

Features

• Configurable bot name. New "Assistant Name" field in Settings panel. Display name updates throughout the UI: sidebar, topbar, message roles, login page, browser tab title, and composer placeholder. Defaults to "Hermes". Configurable via settings or HERMES_WEBUI_BOT_NAME env var. Server-side sanitization prevents empty names and escapes HTML for the login page. (PR #135, based on #131 by @TaraTheStar)

---

[v0.36.2] OpenRouter model routing fix

April 5, 2026 | 440 tests

Bug Fixes

• OpenRouter models sent without prefix, causing 404 (#116). resolve_model_provider() was stripping the openrouter/ prefix from model IDs (e.g. sending free instead of openrouter/free) when config_provider == 'openrouter'. OpenRouter requires the full provider/model path to route upstream correctly. Fixed with an early return that preserves the complete model ID for all OpenRouter configs. (#127)
• Added 7 unit tests for resolve_model_provider() — first coverage on this function. Tests the regression, cross-provider routing, direct-API prefix stripping, bare models, and empty model.

---

[v0.36.1] Login form Enter key fix

April 5, 2026 | 433 tests

Bug Fixes

• Login form Enter key unreliable in some browsers (#124). onsubmit="return doLogin(event)" returned a Promise (async functions always return a truthy Promise), which could let the browser fall through to native form submission. Fixed with doLogin(event);return false plus an explicit onkeydown Enter handler on the password input as belt-and-suspenders. (#125)

---

[v0.35.1] Model dropdown fixes

April 5, 2026 | 433 tests

Bug Fixes

• Custom providers invisible in model dropdown (#117). cfg_base_url was scoped inside a conditional block but referenced unconditionally, causing a NameError for users with a base_url in config.yaml. Fix: initialize to '' before the block. (#118)
• Configured default model missing from dropdown (#116). OpenRouter and other providers replaced the model list with a hardcoded fallback that didn't include model.default values like openrouter/free or custom local model names. Fix: after building all groups, inject the configured default_model at the top of its provider group if absent. (#119)

---

[v0.34.3] Light theme final polish

April 5, 2026 | 433 tests

Bug Fixes

• Light theme: sidebar, role labels, chips, and interactive elements all broken. Session titles were too faint, active session used washed-out gold, pin stars were near-invisible bright yellow, and all hover/border effects used dark-theme white rgba(255,255,255,.XX) values invisible on cream. Fixed with 46 scoped [data-theme="light"] selector overrides covering session items, role labels, project chips, topbar chips, composer, suggestions, tool cards, cron list, and more. (#105)
• Active session now uses blue accent (#2d6fa3) for strong contrast. Pin stars use deep gold (#996b15). Role labels are solid and high contrast.

---

[v0.34.2] Theme text colors

April 5, 2026 | 433 tests

Bug Fixes

• Light mode text unreadable. Bold text was hardcoded white (invisible on cream), italic was light purple on cream, inline code had a dark box on a light background. Fixed by introducing 5 new per-theme CSS variables (--strong, --em, --code-text, --code-inline-bg, --pre-text) defined for every theme. (#102)
• Also replaced remaining rgba(255,255,255,.08) border references with var(--border), and darkened light theme --code-bg slightly for better contrast.

---

[v0.34.1] Theme variable polish

April 5, 2026 | 433 tests

Bug Fixes

• All non-dark themes had broken surfaces, topbar, and dropdowns. 30+ hardcoded dark-navy rgba/hex values in style.css were stuck on the Dark palette regardless of active theme. Fixed by introducing 7 new CSS variables (--surface, --topbar-bg, --main-bg, --input-bg, --hover-bg, --focus-ring, --focus-glow) defined per-theme, replacing every hardcoded reference. (#100)

---

[v0.31.2] CLI session delete fix

April 5, 2026 | 424 tests

Bug Fixes

• CLI sessions could not be deleted from the sidebar. The delete handler only removed the WebUI JSON session file, so CLI-backed sessions came back on refresh. Added delete_cli_session(sid) in api/models.py and call it from /api/session/delete so the SQLite state.db row and messages are removed too. (#87, #88)

Notes

• The public test suite still passes at 424/424.
• Issue #87 already had a comment confirming the root cause, so no new issue comment was needed here.

[v0.30.1] CLI Session Bridge Fixes

April 4, 2026 | 424 tests

Bug Fixes

• CLI sessions not appearing in sidebar. Three frontend gaps: sessions.js wasn't rendering CLI sessions (missing is_cli_session check in render loop), sidebar click handler didn't trigger import, and the "cli" badge CSS selector wasn't matching the rendered DOM structure. (#58)
• CLI bridge read wrong profile's state.db. get_cli_sessions() resolved HERMES_HOME at server launch time, not at call time. After a profile switch, it kept reading the original profile's database. Now resolves dynamically via get_active_hermes_home(). (#59)
• Silent SQL error swallowed all CLI sessions. The sessions table in state.db has no profile column — the query referenced s.profile which caused a silent OperationalError. The except Exception: return [] handler swallowed it, returning zero CLI sessions. Removed the column reference and added explicit column-existence checks. (#60)

Features

• "Show CLI sessions" toggle in Settings. New checkbox in the Settings panel to show/hide CLI sessions in the sidebar. Persisted server-side in settings.json (show_cli_sessions, default true). When disabled, CLI sessions are excluded from /api/sessions responses. (#61)

---

[v0.28.1] CI Pipeline + Multi-Arch Docker Builds

April 3, 2026 | 426 tests

Features

• GitHub Actions CI. New workflow triggers on tag push (v*). Builds multi-arch Docker images (linux/amd64 + linux/arm64), pushes to ghcr.io/nesquena/hermes-webui, and creates a GitHub Release with auto-generated release notes. Uses GHA layer caching for fast rebuilds.
• Pre-built container images. Users can now docker pull ghcr.io/nesquena/hermes-webui:latest instead of building locally.

---

[v0.18.1] Safe HTML Rendering + Sprint 16 Tests

April 2, 2026 | 289 tests

Features

• Safe HTML rendering in AI responses. AI models sometimes emit HTML tags (<strong>, <em>, <code>, <br>) in their responses. Previously these showed as literal escaped text. A new pre-pass in renderMd() converts safe HTML tags to markdown equivalents before the pipeline runs. Code blocks and backtick spans are stashed first so their content is never touched.
• inlineMd() helper. New function for processing inline formatting inside list items, blockquotes, and headings. The old code called esc() directly, which escaped tags that had already been converted by the pre-pass.
• Safety net. After the full pipeline, any HTML tags not in the output allowlist (SAFE_TAGS) are escaped via esc(). XSS fully blocked -- 7 attack vectors tested.
• Active session gold style. Active session uses gold/amber (#e8a030) instead of blue, matching the logo gradient. Project border-left skipped when active (gold always wins).

Tests

• 74 new tests in test_sprint16.py: static analysis (6), behavioral (10), exact regression (1), XSS security (7), edge cases (51). Total: 289 passed.

---

[v0.17.3] Bug Fixes

April 2, 2026

Bug Fixes

• NameError crash in model discovery. logger.debug() was called in the custom endpoint except block in config.py, but logger was never imported. Every failed custom endpoint fetch crashed with NameError, returning HTTP 500 for /api/models. Replaced with silent pass since unreachable endpoints are expected. (PR #24)
• Project picker clipping and width. Picker was clipped by overflow:hidden on ancestor elements. Width calculation improved with dynamic sizing (min 160px, max 220px). Event listener close handler moved after DOM append to fix reference-before-definition. Reordered picker.remove() before removeEventListener for correct cleanup. (PR #25)

---

[v0.17.2] Model Update

April 2, 2026

Enhancements

• GLM-5.1 added to Z.AI model list. New model available in the dropdown for Z.AI provider users. (Fixes #17)

---

[v0.17.1] Security + Bug Fixes

April 2, 2026 | 237 tests

Security

• Path traversal in static file server. _serve_static() now sandboxes resolved paths inside static/ via .relative_to(). Previously GET /static/../../.hermes/config.yaml could expose API keys.
• XSS in markdown renderer. All captured groups in bold, italic, headings, blockquotes, list items, table cells, and link labels now run through esc() before innerHTML insertion.
• Skill category path traversal. Category param validated to reject / and .. to prevent writing outside ~/.hermes/skills/.
• Debug endpoint locked to localhost. /api/approval/inject_test returns 404 to any non-loopback client.
• CDN resources pinned with SRI hashes. PrismJS and Mermaid tags now have integrity + crossorigin attributes. Mermaid pinned to @10.9.3.
• Project color CSS injection. Color field validated against ^#[0-9a-fA-F]{3,8}$ to prevent style.background injection.
• Project name length limit. Capped at 128 chars, empty-after-strip rejected.

Bug Fixes

• OpenRouter model routing regression. resolve_model_provider() was incorrectly stripping provider prefixes from OpenRouter model IDs (e.g. openai/gpt-5.4-mini became gpt-5.4-mini with provider openai), causing AIAgent to look for OPENAI_API_KEY and crash. Fix: only strip prefix when config.provider explicitly matches that direct-API provider.
• Project picker invisible. Dropdown was clipped by .session-item overflow:hidden. Now appended to document.body with position:fixed.
• Project picker stretched full width. Added max-width:220px; width:max-content to constrain the fixed-positioned picker.
• No way to create project from picker. Added "+ New project" item at the bottom of the picker dropdown.
• Folder button undiscoverable. Now shows persistently (blue, 60% opacity) when session belongs to a project.
• Picker event listener leak. removeEventListener added to all picker item onclick handlers.
• Redundant sys.path.insert calls removed. Two cron handler imports no longer prepend the agent dir (already on sys.path via config.py).

---

[v0.16.2] Model List Updates + base_url Passthrough

April 1, 2026 | 247 tests

Bug Fixes

• MiniMax model list updated. Replaced stale ABAB 6.5 models with current MiniMax-M2.7, M2.7-highspeed, M2.5, M2.5-highspeed, M2.1 lineup matching hermes-agent upstream. (Fixes #6)
• Z.AI/GLM model list updated. Replaced GLM-4 series with current GLM-5, GLM-5 Turbo, GLM-4.7, GLM-4.5, GLM-4.5 Flash lineup.
• base_url passthrough to AIAgent. resolve_model_provider() now reads base_url from config.yaml and passes it to AIAgent, so providers with custom endpoints (MiniMax, Z.AI, local LLMs) route to the correct API.

---

[v0.16.1] Community Fixes -- Mobile + Auth + Provider Routing

April 1, 2026 | 247 tests

Community contributions from @deboste, reviewed and refined.

Bug Fixes

• Mobile responsive layout. Comprehensive @media(max-width:640px) rules for topbar, messages, composer, tool cards, approval cards, and settings modal. Uses 100dvh with 100vh fallback to fix composer cutoff on mobile browsers. Textarea font-size:16px prevents iOS/Android auto-zoom on focus.
• Reverse proxy basic auth support. All fetch() and EventSource URLs now constructed via new URL(path, location.origin) to strip embedded credentials per Fetch spec. credentials:'include' on fetch, withCredentials:true on EventSource ensure auth headers are forwarded through reverse proxies.
• Model provider routing. New resolve_model_provider() helper in api/config.py strips provider prefix from dropdown model IDs (e.g. anthropic/claude-sonnet-4.6 → claude-sonnet-4.6) and passes the correct provider to AIAgent. Handles cross-provider selection by matching against known direct-API providers.

---

[v0.12.2] Concurrency + Correctness Sweeps

March 31, 2026 | 190 tests

Two systematic audits of all concurrent multi-session scenarios. Each finding became a regression test so it cannot silently return.

Sweep 1 (R10-R12)

• R10: Approval response to wrong session. respondApproval() used S.session.session_id -- whoever you were viewing. If session A triggered a dangerous command requiring approval and you switched to B then clicked Allow, the approval went to B's session_id. Agent on A stayed stuck. Fixed: approval events tag _approvalSessionId; respondApproval() uses that.
• R11: Activity bar showed cross-session tool status. Session A's tool name appeared in session B's activity bar while you were viewing B. Fixed: setStatus() in the tool SSE handler is now inside the activeSid guard.
• R12: Live tool cards vanished on switch-away and back. Switching back to an in-flight session showed empty live cards even though tools had fired. Fixed: loadSession() INFLIGHT branch now restores cards from S.toolCalls.

Sweep 2 (R13-R15)

• R13: Settled tool cards never rendered after response completes. renderMessages() has a !S.busy guard on tool card rendering. It was called with S.busy=true in the done handler -- tool cards were skipped every time. Fixed: S.busy=false set inline before renderMessages().
• R14: Wrong model sent for sessions with unlisted model. send() used $('modelSelect').value which could be stale if the session's model isn't in the dropdown. Fixed: now uses S.session.model || $('modelSelect').value.
• R15: Stale live tool cards in new sessions. newSession() didn't call clearLiveToolCards(). Fixed.

---

[v0.12.1] Sprint 10 Post-Release Fixes

March 31, 2026 | 177 tests

Critical regressions introduced during the server.py split, caught by users and fixed immediately.

• uuid not imported in server.py -- chat/start returned 500 (NameError) on every new message
• AIAgent not imported in api/streaming.py -- agent thread crashed immediately, SSE returned 404
• has_pending not imported in api/streaming.py -- NameError during tool approval checks
• Session.__init__ missing tool_calls param -- 500 on any session with tool history
• SSE loop did not break on cancel event -- connection hung after cancel
• Regression test file added (tests/test_regressions.py): 10 tests, one per introduced bug. These form a permanent regression gate so each class of error can never silently return.
