## [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)
-`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)
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`.
## [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:
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)
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)
- Original PR by @Hinotoi-agent (cherry-picked; branch was 6 commits behind master)
- 1053 tests total (up from 1051; 2 pre-existing test_sprint5 isolation failures on master, not introduced by this PR)
## [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
-`tests/test_mobile_layout.py`: updated to accept `handleWorkspaceClose()` as valid onclick
-`tests/test_regressions.py`: widened delete handler window to 1200 chars
`/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
-`tests/test_sprint3.py`: 2 new regression tests — absolute-path payload rejected and file preserved, traversal payload rejected and file preserved
- Original PR by @Hinotoi-agent (cherry-picked; branch was 4 commits behind master)
## [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
-`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`)
-`tests/test_opencode_providers.py`: structural regression test verifying the dedicated `openai-codex` branch exists and calls `get_codex_model_ids()`
## [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
- Original PR by @franksong2702 (cherry-picked onto master; branch was 31 commits behind)
## [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`. Added 2 regression tests.
## [v0.50.27] feat: relative time labels in session sidebar (#394)
-`static/sessions.js`: new `_sessionCalendarBoundaries()` (DST-safe via `new Date(y,m,d)` construction), `_localDayOrdinal()`, `_formatSessionDate()` (includes year for dates from prior years); `_formatRelativeSessionTime()` now uses calendar midnight boundaries consistent with `_sessionTimeBucketLabel()` — no more label/bucket mismatch; all relative time strings call `t()` for localization; meta row only appended when non-empty (removes redundant group-header fallback); dead `ONE_DAY` constant removed
-`static/style.css`: add `session-item.active .session-title{color:#1a5a8a}` to light-theme block (fixes active title color in light mode)
-`static/i18n.js`: 11 new i18n keys (`session_time_*`) in both English and Spanish locale blocks; callable keys use arrow-function pattern consistent with existing `n_messages`
-`tests/test_session_sidebar_relative_time.py`: 5 tests — structural presence checks, behavioral Node.js tests via subprocess (yesterday/week boundary correctness, `just now` threshold, year-in-date for old sessions, full i18n key coverage for en+es)
- Original PR by @Jordan-SkyLF (two-pass review: blocking issues fixed in second commit)
## [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
-`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)
-`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/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)
## [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
-`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`)
- **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.
- **`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.
- 15 new structural tests in `tests/test_issue357.py`; 915 tests total (up from 900)
- **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 (`<divclass="katex-block">`)
-`$...$` and `\(...\)` → inline math (`<spanclass="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)
- **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)
- **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.
- **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)
- **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)
Major UI overhaul by **[@aronprins](https://github.com/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](https://github.com/kevin-ho)** in PR #168.
- **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).
- **Preserve user-renamed session titles** (PR #301 by **[@franksong2702](https://github.com/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.
- **Clickable breadcrumb navigation** (PR #302 by **[@franksong2702](https://github.com/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.
## [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."
- **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.
- **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.
- **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)
- **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.
- **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
- **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).
- **`/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`.
- **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 `&lt;code&gt;` 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)**
- **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
- **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**.
- **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`.
- **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.
- **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.
- **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).
- **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`.
- **German translation** (PR #190 by **[@DavidSchuchert](https://github.com/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`.
- **Custom slash-model routing** (PR #189 by **[@smurmann](https://github.com/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.
### 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.
- **`/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).
- **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`.
- **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.
- **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.
- **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.
- **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.
- **`/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)
- **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.
- **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)
- **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)
- **ENV race condition (HIGH):** Two concurrent sessions could interleave `os.environ` writes, clobbering workspace and session keys. Fixed with a global `_ENV_LOCK` in `streaming.py` that serializes the env save/restore block across all sessions. (#108)
- **Predictable signing key (MEDIUM):** Session cookies were signed with `sha256(STATE_DIR)` -- deterministic and forgeable if the install path is known. Now generates a cryptographically random 32-byte key on first startup, persisted to `STATE_DIR/.signing_key` (chmod 600). (#108)
- **Upload path traversal (MEDIUM):** Filenames like `..` survived the `[^\w.\-]` sanitization regex because dots are allowed. Fixed by rejecting dot-only filenames and validating the resolved path stays within the workspace sandbox via `safe_resolve_ws()`. (#108)
- **Weak password hashing (MEDIUM):** Bare SHA-256 with a predictable salt replaced with PBKDF2-SHA256 at 600k iterations (OWASP recommendation) using the random signing key as salt. No new dependencies (stdlib `hashlib.pbkdf2_hmac`). (#108)
**Breaking change:** Existing session cookies and password hashes are invalidated on first restart after upgrade. Users with password auth enabled will need to re-set their password.
- **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.
- **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.
- **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)
- **Opt-in `/insights` sync.** New "Sync usage to /insights" setting (default: off). When enabled, after each turn the WebUI mirrors session token usage, cost, model, and title into `state.db` so `hermes /insights` includes browser session activity. (#92, #93)
### Bug Fixes
- **state_sync.py correctness fixes.** Three bugs in the initial implementation caught during code review: wrong class name (`HermesState` → `SessionDB`), wrong constructor argument type (`str` → `Path`), wrong title update method (`_execute_write` with bad signature → `set_session_title`). Also fixed a SQLite connection leak (persistent connection opened per call, never closed). (#95)
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.
