+## [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 💡 "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)
+
+---
+
+## [v0.36] Self-Update Checker with One-Click Update
+*April 5, 2026 | 433 tests*
+
+### Features
+- **Update checker.** Non-blocking background check on boot detects when the
+  WebUI or hermes-agent git repos are behind upstream. Blue banner shows
+  "WebUI: N updates, Agent: N updates available" with Update Now / Later.
+- **One-click update.** "Update Now" runs `git stash && git pull --ff-only &&
+  git stash pop` on each behind repo, then reloads the page. Concurrent update
+  attempts blocked via lock. Dirty working trees safely stashed and restored.
+- **Settings toggle.** "Check for updates" checkbox in Settings panel. Persisted
+  server-side. Disabled = no background fetch, no banner.
+- **30-minute cache.** Git fetch runs at most twice per hour regardless of tab
+  count. Results cached server-side with TTL.
+- **Session-scoped dismissal.** "Later" dismisses banner for the current tab
+  session (sessionStorage). New tabs get a fresh check.
+- **Test mode.** `?test_updates=1` URL param shows the banner with fake data
+  (localhost only) for UI testing without needing to actually be behind.
+
+### Architecture
+- New `api/updates.py`: `check_for_updates()`, `apply_update()`. Thread-safe
+  caching with `_cache_lock`. Concurrent apply blocked with `_apply_lock`.
+  Default branch auto-detected (master/main).
+- `api/routes.py`: `GET /api/updates/check`, `POST /api/updates/apply`.
+  Simulate endpoint gated to 127.0.0.1.
+- `static/ui.js`: `_showUpdateBanner()`, `dismissUpdate()`, `applyUpdates()`.
+- `static/boot.js`: fire-and-forget check on boot (does not block UI).
+- `api/config.py`: `check_for_updates` in settings defaults + bool keys.
+- Docker safe: all git ops gated by `.git` directory existence check.

+## [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)
+
+---
+
+## [v0.35] Security hardening
+*April 5, 2026 | 433 tests*
+
+### Security fixes
+- **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.
+
+---
+
+## [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)
+
+---
+
+## [v0.34] Sprint 26 -- Pluggable UI Themes
+*April 5, 2026 | 433 tests*
+
+### Features
+- **6 built-in themes.** Dark (default), Light, Slate, Solarized Dark, Monokai,
+  Nord. Defined as CSS variable overrides on `:root[data-theme="name"]` — the
+  entire UI adapts automatically.
+- **Theme picker in Settings.** Dropdown with instant live preview. Changes
+  apply immediately as you click through options.
+- **`/theme` slash command.** `/theme dark`, `/theme light`, etc.
+- **Theme persistence.** Saved server-side in `settings.json` and client-side
+  in `localStorage` for flicker-free loading on page refresh.
+- **Flash prevention.** Inline `<script>` in `<head>` reads localStorage before
+  the stylesheet loads — no flash of the wrong theme.
+- **Custom theme support.** Any theme name is accepted (no enum gate). Create a
+  `:root[data-theme="name"]` CSS block and it works. See `THEMES.md`.
+- **Unsaved changes guard.** Settings panel now tracks dirty state and shows a
+  "You have unsaved changes" bar with Save/Discard buttons when closing with
+  unpersisted changes. Theme preview reverts on discard.
+
+### Architecture
+- `static/style.css`: 6 theme blocks using CSS variable overrides. Light theme
+  includes scrollbar and selection overrides.
+- `static/commands.js`: `/theme` command with validation.
+- `static/panels.js`: Settings dirty tracking, revert-on-discard, unsaved bar.
+- `static/boot.js`: Theme applied from server settings on boot.
+- `api/config.py`: `theme` field in `_SETTINGS_DEFAULTS` (no enum gate).
+- `THEMES.md`: Full documentation for creating custom themes.
+
+### Tests
+- 9 new tests in `test_sprint26.py`: default theme, round-trip persistence for
+  all 6 built-in themes, custom theme acceptance, settings isolation.
+  Total: **433 tests**.
+

+
+## [v0.33] /insights Sync + state.db Bridge Fix
+*April 5, 2026 | 424 tests*
+
+### Features
+- **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)
+
+---
+
+## [v0.32] Auto-Compaction Handling + /compact Command (Issue #90)
+*April 5, 2026 | 424 tests*
+
+### Features
+- **Auto-compaction detection.** When the agent's `run_conversation()` triggers
+  context compression and rotates the session ID, the WebUI detects the mismatch
+  and renames the session file + cache entry so messages don't split across files.
+- **`compressed` SSE event.** Frontend receives a notification when compression
+  fires, shows a system message ("Context was auto-compressed") and a toast.
+- **`/compact` slash command.** Type `/compact` to request the agent compress
+  the conversation context. Sends a natural-language message that triggers the
+  agent's compression preflight.
+- **Real context window data.** The context usage indicator now uses actual
+  `context_length`, `threshold_tokens`, and `last_prompt_tokens` from the agent's
+  compressor instead of the client-side model name lookup. Tooltip shows the
+  auto-compress threshold. Hides gracefully when the agent has no compressor.
+
+### Architecture
+- `api/streaming.py`: Session ID mismatch detection after `run_conversation()`,
+  file rename, SESSIONS cache update under lock, `compressed` SSE event,
+  `context_length`/`threshold_tokens`/`last_prompt_tokens` in usage dict.
+- `static/commands.js`: `/compact` command.
+- `static/messages.js`: `compressed` SSE event handler.
+- `static/ui.js`: `_syncCtxIndicator()` rewritten to use server-side compressor
+  data instead of client-side model estimates.
+
+---
+
+## [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.
+
+## [v0.31] UI Polish + Deployment Hardening
+*April 4, 2026 | 424 tests*
+
+### Bug Fixes
+- **Profile dropdown overlaps chat messages.** `.topbar` had no stacking context,
+  causing the dropdown to paint over `.messages`. Added `position:relative;z-index:10`
+  to `.topbar`. (#71)
+- **Workspace dropdown clipped by sidebar.** `.sidebar overflow:hidden` swallowed
+  the upward-opening workspace dropdown entirely. Changed to `overflow:visible`
+  (scroll lives on `.session-list`); added `position:relative;z-index:10` to
+  `.sidebar-bottom`. (#71)
+- **Slash-command autocomplete behind tool cards.** `.composer-wrap` had
+  `position:relative` but no `z-index`, letting tool cards bleed over it.
+  Added `z-index:10`. (#71)
+- **Skill picker clipped inside Settings modal.** `.settings-panel overflow-y:auto`
+  clipped the absolute-positioned skill picker. Moved scroll to `.settings-body`,
+  set panel to `overflow:visible`, raised skill picker to `z-index:1100`. (#71)
+- **CLI session badge blocks action buttons on hover.** Added
+  `.session-item.cli-session:hover::after { display:none }` so the gold "cli"
+  label hides on hover, making archive/delete/pin fully reachable. (#71)
+- **Workspace dropdown name and path crowded on same line.** `.ws-opt` was a plain
+  block with inline spans. Added `flex-direction:column;gap:4px` so name and path
+  stack cleanly. (#71)
+- **Both servers sharing same state directory.** `api/config.py` and `start.sh`
+  both defaulted to `~/.hermes/webui-mvp` (an internal dev name). Changed default
+  to `~/.hermes/webui` -- generic, appropriate for any deployment. Override with
+  `HERMES_WEBUI_STATE_DIR`. (#72, #73)
+
+---
+
+## [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)
+
+---
+
+## [v0.30] CLI Session Bridge (Community: @thadreber-web)
+*April 4, 2026 | 424 tests*
+
+### Features
+- **CLI session bridge.** The WebUI now reads sessions from the hermes-agent's
+  SQLite store (`state.db`). CLI sessions appear in the sidebar with a gold
+  "cli" indicator badge. Click to import into the WebUI store with full message
+  history — replies then work through the normal agent pipeline.
+- **`/api/session/import_cli` endpoint.** Imports a CLI session into the WebUI
+  JSON store. Idempotent — returns existing session if already imported.
+  Derives title from first message, inherits active profile and workspace.
+- **`/api/sessions` merges CLI sessions.** Sidebar shows both WebUI and CLI
+  sessions sorted by last activity. Deduplication ensures WebUI sessions take
+  priority when the same session_id exists in both stores.
+- **CLI session fallback on `/api/session`.** If a session_id isn't found in
+  the WebUI store, falls back to reading from the CLI SQLite store.
+
+### Architecture
+- `api/models.py`: `get_cli_sessions()`, `get_cli_session_messages()`,
+  `import_cli_session()`. All use parameterized SQL queries and `with` for
+  connection management. Graceful fallback on missing sqlite3 or state.db.
+- `api/routes.py`: CLI fallback in GET `/api/session`, merged list in
+  GET `/api/sessions`, POST `/api/session/import_cli`.
+- `static/style.css`: `.cli-session` indicator styles (gold border + badge).
+
+---
+
+## [v0.29] Sprint 23: Agentic Transparency + Polish
+*April 4, 2026 | 424 tests*
+
+### Features
+
+- **Token/cost display.** Agent usage (input tokens, output tokens, estimated
+  cost) is now read after each conversation and persisted on the session.
+  A muted badge appears below the last assistant message when enabled.
+  Off by default — toggle via the Settings panel checkbox or `/usage` slash
+  command. Persists server-side across refreshes.
+
+- **Subagent delegation cards.** `subagent_progress` events now render with
+  a 🔀 icon and a blue indented left border to visually distinguish child
+  tool activity from parent tool calls. `delegate_task` cards display as
+  "Delegate task" with cleaner formatting.
+
+- **Skill picker in cron create form.** The "New Job" form now has a search
+  input + tag chip picker for attaching skills to cron jobs. Skills fetched
+  from `/api/skills`, filtered on keyup, added/removed as tag chips.
+  `submitCronCreate()` sends `skills` array in the POST body. Backend already
+  supported the field — this was a pure frontend gap.
+
+- **Skill linked files viewer.** Skill preview panel now renders a "Linked
+  Files" section below SKILL.md content when a skill has `references/`,
+  `templates/`, `scripts/`, or `assets/` subdirectories. Clicking a file
+  loads it in the preview panel with syntax highlighting.
+  New `file` query param on `GET /api/skills/content` serves linked files
+  with path traversal protection.
+
+- **Workspace tree state persists across refreshes.** Expanded directory
+  paths are saved to `localStorage` keyed by workspace path
+  (`hermes-webui-expanded:{path}`). On every root load (page refresh,
+  session switch), the saved state is restored and previously-expanded
+  directories are pre-fetched so the tree renders fully on first paint.
+
+- **Timestamps fixed.** `api/streaming.py` now stamps `timestamp` on every
+  message that lacks one at conversation completion. The `done` SSE event
+  also stamps `_ts` on the last assistant message immediately. Timestamps
+  were already rendered in the UI (Sprint 14, hover-to-reveal) but most
+  messages had no timestamp field, so nothing ever showed.
+
+- **`/usage` slash command.** Instant toggle for token usage display.
+  Shows a toast, persists to server, updates the Settings checkbox if open,
+  re-renders immediately.
+
+### Bug Fixes
+
+- **XSS via inline onclick + esc().** Skill names and file paths embedded in
+  `onclick` HTML attributes used `esc()` for encoding. `esc()` converts `'`
+  to `&#39;` (HTML-safe) but browsers decode it back before executing JS,
+  allowing skill names with apostrophes to break out of string literals.
+  Fixed by switching to `data-*` attributes + `addEventListener`.
+
+- **rglob wildcard injection.** The `name` query param for
+  `/api/skills/content?file=` was passed directly to `SKILLS_DIR.rglob()`,
+  which accepts glob patterns. `name=*` would match an arbitrary directory
+  and use it as the trust base for path traversal checking.
+  Fixed by rejecting names containing `* ? [ ]` metacharacters with 400.
+
+- **`_fmtTokens(null)` returned "null".** `String(null)` = `"null"` would
+  appear in the usage badge for sessions missing fields. Fixed with a
+  `!n || n < 0` guard returning `'0'`.
+
+- **Usage badge on wrong row.** Badge used `:last-child` which could target
+  a user message row. Fixed by adding `data-role` to message rows and
+  scanning backwards for the last `assistant` row.
+
+- **Tool name resolution.** Tool call entries in session JSON sometimes
+  stored the literal string `"tool"` as the name when the call ID couldn't
+  be resolved. Fixed: defaults to empty string and skips unresolvable entries.
+
+- **Inline import inside loop.** `import json as _j2` inside the done-handler
+  loop in `streaming.py` moved to module-level.
+
+### Session Model
+
+- Added `input_tokens`, `output_tokens`, `estimated_cost` fields to Session
+  (defaults: 0, 0, None). Included in `compact()`, session JSON, and all
+  API responses. Backward-compatible via `**kwargs`.
+
+- Added `args` capture to `tool_calls` session JSON entries (truncated
+  snapshot of tool inputs, up to 6 keys / 120 chars each).
+
+### Settings
+
+- New `show_token_usage` boolean setting (default: `false`). Stored in
+  `settings.json`, loaded on boot alongside `send_key`.
+
+### Tests
+
+- Renamed `test_sprint24.py` → `test_sprint23.py`.
+- Strengthened session usage assertions (explicit field presence checks).
+- Added: path traversal rejection test, wildcard name rejection test,
+  cron create with skills array test.
+- Total: 424 tests (up from 415).
+
+---
+
+## [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.
+
+---
+
+## [v0.27] Profile Creation Fallback for Docker (Issue #44)
+*April 3, 2026 | 426 tests*
+
+### Bug Fixes
+- **Profile creation works without hermes-agent.** In Docker containers where
+  `hermes_cli` is not importable, profile creation now falls back to a local
+  implementation that creates the directory structure and optionally clones
+  config files. Previously returned `RuntimeError` with "hermes-agent required".
+- **Name validation uses `fullmatch()`.** Prevents trailing-newline bypass of
+  the `$` anchor in `re.match()`. Not reachable from the web UI (name is
+  stripped), but fixed for defense-in-depth.
+- **`clone_from` validated in `create_profile_api()`.** Defense-in-depth:
+  prevents path traversal if called by a non-HTTP client.
+- **Fallback return uses full 9-key schema.** Previously returned only 2 keys
+  (`name`, `path`), inconsistent with the normal response shape.
+- **Atomic directory creation.** `mkdir(exist_ok=False)` prevents TOCTOU race
+  on concurrent profile creates.
+
+### Architecture
+- `api/profiles.py`: `_validate_profile_name()`, `_create_profile_fallback()`,
+  `_PROFILE_ID_RE`, `_PROFILE_DIRS`, `_CLONE_CONFIG_FILES` constants matching
+  upstream `hermes_cli.profiles`.
+- `docker-compose.yml`: Removed `:ro` from `~/.hermes` mount (required for
+  profile writes). Localhost-only binding preserved.
+
+---
+
+## [v0.26] Profile System Polish -- 10 Post-Sprint-23 Fixes
+*April 3, 2026 | 426 tests*
+
+### Bug Fixes
+- **Profile switch base dir bug.** When `HERMES_HOME` was mutated to a
+  `profiles/` subdir at startup, `switch_profile()` doubled the path
+  (e.g. `~/.hermes/profiles/X/profiles/X`). New `_resolve_base_hermes_home()`
+  detects profile subdirs and walks up to the actual base.
+- **Cross-provider model routing.** Picking a model from a different provider
+  than the config's default now routes through OpenRouter instead of trying
+  a direct API call to a provider whose key may not exist.
+- **Legacy sessions missing profile tag.** `all_sessions()` now backfills
+  `profile='default'` for pre-Sprint-22 sessions so the profile filter works.
+- **Workspace list cleanup.** Stale paths, test artifacts, and cross-profile
+  entries are now cleaned on load. Legacy global workspace file migrated
+  once for the default profile.
+- **API error messages.** `api()` helper now parses JSON error bodies and
+  surfaces the human-readable message instead of raw JSON.
+- **Workspace dropdown moved to sidebar.** The workspace picker now opens
+  upward from the sidebar bottom instead of clipping behind the topbar.
+
+### Features
+- **Rate limit error display.** Rate limit errors (429) now show a distinct
+  card with a rate limit icon and hint, instead of the generic error message.
+- **SSE `apperror`/`warning` events.** Server can send typed error events
+  that the frontend handles with appropriate UX (rate limit card, fallback
+  notice, etc.).
+- **Smart model resolver.** `_findModelInDropdown()` handles name mismatches
+  between config model IDs and dropdown values (e.g. `claude-sonnet-4-6` vs
+  `anthropic/claude-sonnet-4.6`).
+- **Profile switch starts new session.** When the current session has messages,
+  switching profiles automatically starts a fresh session to prevent
+  cross-profile tagging.
+- **Per-profile toolsets.** Agent now reads `platform_toolsets.cli` from the
+  active profile's config at call time, not the boot-time snapshot.
+- **Per-profile fallback model.** `fallback_model` config is read from the
+  active profile and passed to AIAgent.
+
+### Architecture
+- `api/profiles.py`: `_resolve_base_hermes_home()` replaces naive env var read.
+- `api/workspace.py`: `_clean_workspace_list()`, `_migrate_global_workspaces()`.
+- `api/streaming.py`: Per-profile toolsets and fallback model at call time.
+- `api/models.py`: `all_sessions()` backfills `profile='default'`.
+- `static/ui.js`: `_findModelInDropdown()`, `_applyModelToDropdown()`.
+- `static/messages.js`: `apperror` and `warning` SSE event handlers.
+
+---
+
+## [v0.25] Sprint 23 -- Profile/Workspace/Model Coherence
+*April 3, 2026 | 423 tests*
+
+### Features
+- **Profile-local workspace storage.** Each named profile now stores its own
+  `workspaces.json` and `last_workspace.txt` under `{profile_home}/webui_state/`.
+  Default profile continues using the global STATE_DIR for backward compat.
+- **Profile switch returns defaults.** `POST /api/profile/switch` response now
+  includes `default_model` and `default_workspace` from the new profile's
+  config.yaml, enabling one-round-trip state sync.
+- **Session profile filter.** Session sidebar filters to the active profile by
+  default. "Show N from other profiles" toggle reveals sessions from all
+  profiles, modeled on the existing archived toggle. Resets on profile switch.
+
+### Bug Fixes
+- **Model picker ignores profile on switch.** `switchToProfile()` now clears
+  the `hermes-webui-model` localStorage key so the profile's default model
+  applies instead of a stale preference from another profile.
+- **Workspace list was global.** Switching profiles no longer shows the wrong
+  profile's workspaces.
+- **`DEFAULT_WORKSPACE` was a boot-time singleton.** Now resolved dynamically
+  through `_profile_default_workspace()`.
+- **Session list showed all profiles.** Now filtered to active profile.
+- **`switchToProfile()` didn't refresh workspaces or sessions.** Now refreshes
+  workspace list, session list, and resets profile filter on switch.
+
+### Architecture
+- `api/workspace.py` rewritten with profile-aware path resolution.
+- `api/profiles.py`: `switch_profile()` returns `default_model` and
+  `default_workspace`.
+- `static/sessions.js`: Profile filter with toggle UI.
+- `static/panels.js`: Full cascade refresh on profile switch.
+- 8 new tests in `test_sprint23.py`.
+
+---
+
+## [v0.24] Sprint 22 -- Multi-Profile Support (Issue #28)
+*April 3, 2026 | 415 tests*
+
+### Features
+- **Profile picker (topbar).** Purple-accented chip with SVG user icon. Click
+  to open dropdown listing all profiles with gateway status dots (green =
+  running), model info, and skill count. Click any profile to switch; "Manage
+  profiles" link opens the sidebar panel.
+- **Profiles management panel.** New sidebar tab with full CRUD UI. Profile
+  cards show name, model/provider, skill count, API key status, and gateway
+  status badge. "Use" button switches profile, delete button removes non-default
+  profiles (with confirmation).
+- **Profile creation.** "+ New profile" form with name validation (`[a-z0-9_-]`),
+  optional "clone config from active" checkbox. Wraps the CLI's
+  `hermes_cli.profiles.create_profile()`.
+- **Profile deletion.** Confirm dialog. Auto-switches to default if deleting
+  the active profile. Blocked while agent is running.
+- **Seamless profile switching.** No server restart. Profile switch updates
+  `HERMES_HOME`, patches module-level caches in hermes-agent's `skills_tool`
+  and `cron/jobs`, reloads `.env` API keys and `config.yaml`, refreshes the
+  model dropdown, skills, memory, and cron panels.
+- **Per-session profile tracking.** `profile` field on Session records which
+  profile was active at creation. Backward-compatible (`null` for old sessions).
+
+### Bug Fixes
+- **Hardcoded `~/.hermes` paths.** Memory read/write and model discovery used
+  hardcoded paths. Now resolved through `get_active_hermes_home()`.
+- **Module-level path caching.** hermes-agent modules snapshot `HERMES_HOME`
+  at import time. Profile switch now monkey-patches `SKILLS_DIR`, `CRON_DIR`,
+  `JOBS_FILE`, `OUTPUT_DIR` so they track the active profile.
+
+### Architecture
+- New `api/profiles.py`: profile state management wrapping `hermes_cli.profiles`.
+  Thread-safe (`_profile_lock`). Lazy imports avoid circular deps.
+- `api/config.py`: module-level `cfg` replaced with reloadable `get_config()`
+  / `reload_config()`. Dynamic `_get_config_path()` resolves through profile.
+- `api/streaming.py`: `HERMES_HOME` added to env save/restore block.

+## [v0.23] Sprint 21 -- Mobile Responsive + Docker
+*April 3, 2026 | 415 tests*
+
+### Features
+- **Mobile responsive layout (Issue #21).** Full mobile experience with
+  hamburger sidebar (slide-in overlay), bottom navigation bar (5-tab iOS
+  pattern), and files slide-over panel. Touch targets minimum 44px. Composer
+  positioned above bottom nav. Session clicks auto-close sidebar. Desktop
+  layout completely unchanged — all mobile elements hidden via `@media`.
+- **Docker support (Issue #7).** Dockerfile (`python:3.12-slim`), docker-compose.yml
+  with named volume for state persistence, optional `~/.hermes` mount for
+  agent features. Binds to `127.0.0.1` by default for security.
+
+### Bug Fixes (from review)
+- **CSS cascade broke mobile slide-in.** `position:relative` rules after the
+  media query overrode `position:fixed` on mobile. Wrapped in `@media(min-width:641px)`.
+- **mobileSwitchPanel() always reopened sidebar.** Chat tab now closes sidebar
+  instead of reopening it over the main chat area.
+- **Dockerfile missing pip install.** Added `pip install -r requirements.txt`.
+- **No .dockerignore.** Added exclusions for `.git`, `tests/`, `.env*`.
+- **docker-compose tilde expansion.** Changed `~/.hermes` default to
+  `${HOME}/.hermes` (Docker Compose doesn't shell-expand `~`).
+
+### Architecture
+- Mobile navigation functions in `boot.js`: `toggleMobileSidebar()`,
+  `closeMobileSidebar()`, `toggleMobileFiles()`, `mobileSwitchPanel()`.
+- `sessions.js`: `closeMobileSidebar()` called after session click.
+- 69 new CSS lines in `@media(max-width:640px)` block.
+- New files: `Dockerfile`, `docker-compose.yml`, `.dockerignore`.

+
+## [v0.22] Sprint 20 -- Voice Input + Send Button Polish
+*April 3, 2026 | 415 tests*
+
+### Features
+- **Voice input via Web Speech API.** Microphone button in the composer.
+  Tap to start recording, tap again (or send) to stop. Live interim
+  transcription appears in the textarea. Auto-stops after ~2s of silence.
+  Final text stays editable before sending. Appends to existing textarea
+  content rather than replacing it. Button hidden when browser doesn't
+  support Web Speech API. No API keys, no external libraries, no server
+  changes. Works in Chrome, Edge, Safari (partial). Firefox unsupported
+  (button stays hidden).
+- **Send button polish.** Send button redesigned as a 34px icon-only circle
+  with upward arrow SVG. Hidden by default — appears with pop-in spring
+  animation when textarea has content or files are attached. Disappears
+  on send or when content is cleared. Hidden while agent is responding.
+  Blue fill (#7cb9ff) with glow, scale hover/active for tactile feedback.
+
+### Architecture
+- Voice input IIFE in `boot.js`: SpeechRecognition lifecycle with
+  `continuous=false`, `interimResults=true`, error handling via `showToast()`.
+- `_prefix` variable snapshots existing textarea content on recording start
+  so dictation appends rather than overwrites.
+- `btnSend.onclick` stops active recognition before sending (send guard).
+- CSS: `.mic-btn`, `.mic-btn.recording` (red pulse), `.mic-status`,
+  `.mic-dot`, `@keyframes mic-pulse`.
+- `updateSendBtn()` in `ui.js` tracks textarea content, pending files,
+  and busy state. Hooked into `setBusy()`, `renderTray()`, `autoResize()`,
+  and input event listener.
+- CSS: `.send-btn` redesigned (circle, glow), `.send-btn.visible` +
+  `@keyframes send-pop-in` (spring animation).
+
+### Tests
+- 52 new tests in `test_sprint20.py`: voice input HTML, CSS, JS, append
+  behaviour, error handling, regressions.
+- 33 new tests in `test_sprint20b.py`: send button HTML, CSS, JS,
+  animation, visibility logic, regressions. Total: **415 tests**.
+
+---
+
+## [v0.21] Sprint 19 -- Auth + Security Hardening
+*April 3, 2026 | 328 tests*
+
+### Features
+- **Password authentication (Issue #23).** Optional password auth, off by default.
+  Enable via `HERMES_WEBUI_PASSWORD` env var or Settings panel. Password-only
+  (single-user app). Signed HMAC HTTP-only cookie with 24h TTL. Minimal dark-themed
+  login page at `/login`. API calls without auth return 401; page loads redirect.
+  New `api/auth.py` module with hashing, verification, session management.
+- **Security headers.** All responses now include `X-Content-Type-Options: nosniff`,
+  `X-Frame-Options: DENY`, `Referrer-Policy: same-origin`.
+- **POST body size limit.** Non-upload POST bodies capped at 20MB via `read_body()`.
+- **Settings panel additions.** "Access Password" field and "Sign Out" button
+  (only visible when auth is active).
+
+### Architecture
+- New `api/auth.py`: password hashing (SHA-256 + STATE_DIR salt), signed cookies,
+  auth middleware, public path allowlist.
+- Auth check in `server.py` do_GET/do_POST before routing.
+- `password_hash` added to `_SETTINGS_DEFAULTS`.
+
+### Tests
+- 10 new tests in `test_sprint19.py`: auth status, login flow, security headers,
+  cache-control, settings password field, request size limit. Total: **328 tests (328 passing)**.

+# Why Hermes
+
+Hermes is a persistent, autonomous AI agent that lives on your server. It remembers everything,
+schedules work while you sleep, and gets more capable the longer it runs. This document explains
+the mental model, why that matters, and how Hermes compares to every major AI tool available today.
+
+---
+
+## The Core Idea: Assistants Forget. Agents Don't.
+
+Every time you open Claude Code, Codex, or a chat window, the tool starts from zero. It does not
+know who you are, what you worked on yesterday, how your repo is structured, or what bugs you
+already fixed. You re-explain yourself every single session. The tool is powerful in the moment
+and useless the next day.
+
+Hermes fills that gap. It runs on your server, retains context across every session, and acts
+on your behalf whether or not you are at a keyboard.
+
+```
+Assistant model:  You -> [Tool] -> Answer -> Done
+                  (tool forgets everything when the window closes)
+
+Agent model:      You <-> [Hermes] <-> (memory, skills, schedule, tools)
+                  (persistent, learns your stack, acts on your behalf, runs while you're offline)
+```
+
+---
+
+## The Three Pillars
+
+### 1. Memory That Compounds
+
+Hermes has layered memory that survives every session, every reboot, every model swap:
+
+- **User profile** -- who you are, your preferences, your communication style, things you've
+  corrected Hermes on
+- **Agent memory** -- facts about your environment, your toolchain, your project conventions
+- **Skills** -- reusable procedures Hermes discovers and saves; it never has to relearn how to
+  deploy your app, run your tests, or review a PR
+- **Session history** -- every past conversation is searchable; Hermes can recall what you
+  worked on last Tuesday
+
+When you correct Hermes, it remembers. When it solves a tricky problem, it saves the approach.
+When it learns your stack, that knowledge carries into every future session.
+
+### 2. Autonomous Scheduling
+
+Hermes can run jobs without you present -- every hour, every morning, on any cron schedule.
+It fires up a fresh session, runs the task, and delivers the result to wherever you want it:
+Telegram, Discord, Slack, Signal, WhatsApp, SMS, email, and more.
+
+Things Hermes can do while you sleep:
+
+- Review new pull requests on your GitHub repo and post a full verdict comment
+- Send you a morning briefing of news, markets, or anything else you care about
+- Run your test suite and alert you if something breaks
+- Watch a competitor's blog for new posts and summarize them
+- Monitor a datasource and notify you when a threshold is crossed
+
+### 3. Reach It From Anywhere
+
+Hermes runs on your server and is reachable from every surface: terminal over SSH, the web UI
+(this project), and messaging apps including Telegram, Discord, Slack, WhatsApp, Signal, and
+Matrix. Start a task from your phone, check it from the browser on your laptop, continue it in
+a terminal on a remote server. The same agent, memory, and history follow you everywhere.
+
+---
+
+## A Framework for AI Tools
+
+There are four distinct categories of AI tool. Understanding the category tells you what a tool
+can and cannot do.
+
+### Category 1: Chat Assistants
+*Claude.ai, ChatGPT, Gemini*
+
+You open a window, ask something, get an answer. No persistent memory beyond the conversation,
+no ability to run code or touch files, no way to act on your behalf. Excellent for Q&A,
+drafting, and brainstorming. You re-explain your context every session.
+
+### Category 2: IDE Integrations
+*GitHub Copilot, Cursor, Windsurf, Zed AI*
+
+Deep inside your editor. Autocomplete, inline diffs, refactors -- all excellent. Windsurf was
+earliest with workspace-scoped memory (Cascade Memories); Copilot has been shipping repo-level
+memory since late 2025 and is catching up. Cursor has no native memory as of early 2026. None
+have scheduling or messaging access. Tied to one machine and one editor.
+
+### Category 3: Agentic CLI Tools
+*Claude Code, Codex CLI, OpenCode, Aider*
+
+The current frontier for most developers. Can use real tools -- run shell commands, read and
+write files, search the web, call APIs. Great for deep, multi-step tasks in a single terminal
+session. All are adding memory and scheduling features to varying degrees (see comparisons below),
+but the core model is still session-scoped: you invoke it, it works, it stops.
+
+### Category 4: Persistent Autonomous Agents
+*Hermes, OpenClaw (as of early 2026)*
+
+All the tool use of Category 3, plus memory that accumulates across sessions, plus always-on
+scheduling, plus multi-modal access from any device or messaging app. Gets more useful over time
+rather than resetting to zero. Hermes and OpenClaw are the two primary open-source, self-hosted
+tools in this category. OpenClaw is a gateway-centric automation platform; Hermes is a
+self-improving agent that writes and reuses its own procedures from experience.
+
+---
+
+## How Hermes Compares
+
+### vs. OpenClaw
+
+OpenClaw is the most direct comparison to Hermes and the question most people ask first.
+Both are open-source, self-hosted, always-on agents with persistent memory, cron scheduling,
+and messaging app integration. If you're evaluating Hermes, you should evaluate OpenClaw too.
+
+OpenClaw (MIT, ~347k GitHub stars) is built around a **Gateway** control plane written in
+Node.js/TypeScript. It excels at broad personal automation: native Chrome/Chromium control for
+browser automation, the widest messaging platform support in the space (WhatsApp, Telegram,
+Signal, iMessage, LINE, WeChat, Slack, Discord, Teams, Matrix, and more), voice wake words,
+and a ClawHub skill marketplace where users share pre-built automations. The community is large
+and the ecosystem is growing fast.
+
+Hermes takes a different approach. It is built in Python and centers on a **self-improving
+agent loop** rather than a gateway control plane. The core difference is in how skills work:
+OpenClaw skills are primarily human-authored plugins installed from a marketplace; Hermes
+**writes and saves its own skills automatically** as part of every session. When Hermes solves
+a problem a new way, it saves the procedure and reuses it going forward without any user effort.
+
+Beyond the skills architecture, there are two other practical differences worth knowing:
+
+**Stability.** OpenClaw's community forums and GitHub issues document a recurring pattern of
+update-breaking regressions -- for example, Telegram integration was broken across multiple
+releases in early 2026. The unofficial WhatsApp Web protocol OpenClaw uses is known to
+disconnect and requires periodic re-pairing (this is documented in OpenClaw's own FAQ).
+Hermes has had no equivalent release breakages.
+
+**Security.** ClawHub's open publishing model has been exploited repeatedly. A community audit
+identified over a thousand malicious skills in the marketplace including prompt injections and
+tool-poisoning payloads; the community-maintained awesome-openclaw-skills list tracks confirmed
+removals and flags known bad actors. Hermes has no third-party marketplace and a correspondingly
+smaller attack surface.
+
+**OpenClaw's genuine strengths** are worth stating plainly: it has broader messaging coverage
+(iMessage, LINE, WeChat, Teams -- platforms Hermes does not support), native browser and
+computer control via Chrome CDP, voice wake words on macOS and iOS, a larger community, and
+more third-party integrations than Hermes. If those capabilities matter most to you, OpenClaw
+is worth a serious look.
+
+Where Hermes is the better fit: you want an agent that self-improves from experience without
+manual plugin authoring, you work in Python and want access to the ML/data science ecosystem,
+you want a stable deployment that does not break between updates, or you want a full web chat
+UI rather than a monitoring dashboard.
+
+| | OpenClaw | Hermes |
+|---|---|---|
+| Persistent memory | Yes | Yes |
+| Scheduled jobs (cron) | Yes | Yes |
+| Messaging app access | Yes (15+ platforms, incl. iMessage/WeChat) | Yes (10+ platforms) |
+| Web UI | Gateway dashboard (monitoring only) | Full three-panel chat UI |
+| Self-hosted | Yes | Yes |
+| Open source | Yes (MIT) | Yes |
+| Self-improving skills | Partial (AI can generate skills; not the default loop) | Yes (automatic, first-class) |
+| Browser / computer control | Yes (native Chrome CDP) | Via shell / tools |
+| Voice wake words | Yes (macOS/iOS) | No |
+| Python / ML ecosystem | No (Node.js) | Yes |
+| Orchestrates Claude Code / Codex | No | Yes |
+| Multi-profile support | Via binding-rule routing | Yes (first-class named profiles) |
+| Provider-agnostic | Yes | Yes |
+| Update reliability | Moderate (documented regressions) | High |
+
+### vs. Claude Code (Anthropic)
+
+Claude Code is Anthropic's official agentic CLI and one of the best tools in Category 3.
+In a single focused session it is capable -- deep code understanding, shell access, file
+editing, multi-step reasoning.
+
+Claude Code has been adding features rapidly and the gap is narrowing:
+
+- **Hooks system** -- 13 event types (SessionStart, PreToolUse, PostToolUse, Stop, etc.) with
+  4 handler types (shell command, HTTP endpoint, LLM prompt, sub-agent); deterministic
+  non-LLM control over the agent lifecycle
+- **Plugins / Skills** -- installable via `/plugin install`, hot-reloaded from `~/.claude/skills`,
+  with a marketplace; skills and slash commands unified as of v2.1.0
+- **Scheduling** -- `/loop` (session-scoped), cloud-managed cron via `claude.ai/code/scheduled`
+  (Anthropic infrastructure, minimum interval applies), and desktop app automations
+- **Messaging channels** -- Telegram, Discord, iMessage, and webhooks via the Channels feature
+  (research preview, v2.1.80+); deep Slack integration that triggers cloud sessions and creates PRs
+- **Claude Cowork** -- a separate product for knowledge workers; connects to 38+
+  services via MCP including Slack, Gmail, Microsoft Teams, Notion, Jira, Salesforce, and more
+- **Memory** -- CLAUDE.md and MEMORY.md for project-level context; auto-memory rolling out
+
+These are real features. The key differences that remain:
+
+- Claude Code's scheduling runs on **Anthropic's cloud** (or requires the desktop app open),
+  not a self-hosted server; cloud jobs have a minimum interval and your data leaves your hardware
+- Memory is **project-file-based** (CLAUDE.md / MEMORY.md), not a knowledge graph that
+  accumulates automatically across all your work; auto-memory is still rolling out
+- **Not provider-agnostic** -- routes through Bedrock or Vertex but always hits a Claude model;
+  you cannot switch to GPT, Gemini, or a local model
+- **Not open source** -- proprietary; the CLI ships obfuscated JavaScript
+- Messaging channels are a **research preview** requiring Bun runtime; not yet production-grade
+
+Hermes can use Claude Code as a sub-agent. For large implementation tasks, Hermes can spawn
+Claude Code to handle the heavy lifting and fold the result back into its own memory and history.
+
+| | Claude Code | Hermes |
+|---|---|---|
+| Persistent memory (automatic) | Partial (CLAUDE.md / MEMORY.md, rolling out) | Yes |
+| Skills / hooks system | Yes (Hooks + Plugin/Skills marketplace) | Yes (auto-generated from experience) |
+| Scheduled jobs (self-hosted) | No (cloud or desktop-app only) | Yes |
+| Messaging access | Partial (Telegram/Discord/iMessage via research preview; Slack native) | Yes (10+ platforms, production) |
+| Cowork connectors (Slack, Gmail, etc.) | Yes (via Claude Cowork, separate product) | Via agent tool use |
+| Web UI | Yes (claude.ai/code, Anthropic-hosted) | Yes (self-hosted) |
+| Provider-agnostic | No (Claude models only, via Bedrock/Vertex) | Yes (any provider) |
+| Self-hosted scheduling | No | Yes |
+| Open source | No | Yes |
+| Runs as sub-agent of Hermes | Yes | N/A |
+
+### vs. Codex CLI (OpenAI)
+
+Codex CLI is OpenAI's open-source agentic terminal tool (Apache 2.0, ~73k GitHub stars). It
+supports 10+ providers including Anthropic, Google, Mistral, Groq, and local models via Ollama.
+It added persistent session memory in v0.100.0 with `codex resume`. The desktop app has an
+Automations feature for scheduled local tasks.
+
+The CLI itself has no native scheduling (open feature request as of early 2026). Memory is
+session-history-based rather than a living knowledge graph. No messaging app access. A strong
+tool for single-session coding; Hermes adds the always-on layer on top.
+
+| | Codex CLI | Hermes |
+|---|---|---|
+| Persistent memory | Partial (session history + AGENTS.md) | Yes (automatic, layered) |
+| Scheduled jobs | Partial (desktop app only; CLI has none) | Yes |
+| Messaging app access | No | Yes |
+| Web UI | No | Yes (self-hosted) |
+| Provider-agnostic | Yes (10+ providers) | Yes (10+ providers) |
+| Self-hosted | Yes | Yes |
+| Open source | Yes (Apache 2.0) | Yes |
+
+### vs. OpenCode
+
+OpenCode is an open-source TUI agentic coding assistant, provider-agnostic across 75+ providers.
+It has a WebUI embedded in its binary and an official desktop app. It uses SQLite for session
+history and AGENTS.md for project context.
+
+No native scheduled jobs (a community background plugin exists), no first-party messaging
+integration (community Telegram bots exist but require manual setup), and no automatic
+cross-session semantic memory. Good for interactive terminal coding sessions.
+
+| | OpenCode | Hermes |
+|---|---|---|
+| Persistent memory | Partial (session history + AGENTS.md) | Yes (automatic, layered) |
+| Scheduled jobs | No (community plugin only) | Yes |
+| Messaging app access | No (community Telegram bot only) | Yes (first-party, 10+ platforms) |
+| Web UI | Yes (embedded + desktop app) | Yes (self-hosted) |
+| Mobile access | No | Yes |
+| Skills system | No | Yes |
+| Provider-agnostic | Yes (75+ providers) | Yes |
+| Open source | Yes | Yes |
+
+### vs. Cursor / Windsurf / Copilot
+
+Category 2 tools -- exceptional at in-editor autocomplete, inline diffs, and code review.
+Not competing for the same job as Hermes, and they work well alongside it.
+
+Windsurf was earliest with workspace-scoped memory (Cascade Memories); Copilot has been
+shipping repo-level memory since late 2025. Cursor has no native cross-session memory as of
+early 2026. None have scheduling or messaging access.
+
+| | Cursor | Windsurf | Copilot | Hermes |
+|---|---|---|---|---|
+| In-editor autocomplete | Excellent | Excellent | Excellent | No |
+| Inline diff / refactor | Yes | Yes | Yes | Via shell |
+| Cross-session memory | No | Yes (workspace) | Partial (repo, early access) | Yes |
+| Scheduled background jobs | No | No | No | Yes |
+| Messaging app / mobile | No | No | No | Yes |
+| Terminal tool use | Limited | Limited | Limited | Full |
+| Self-hosted | No | No | No | Yes |
+| Provider-agnostic | Partial | Partial | No | Yes |
+| Open source | No | No | No | Yes |
+
+### vs. Claude.ai / ChatGPT
+
+Category 1. For drafting, Q&A, and brainstorming in the moment, both are excellent.
+
+Claude.ai memory has been improving -- it now generates memory from chat history, not just
+user-curated entries. Claude.ai can also execute code and read/write files in a sandboxed
+environment via Artifacts. These are real capabilities, just not the same as direct filesystem
+or shell access on your own server.
+
+| | Claude.ai / ChatGPT | Hermes |
+|---|---|---|
+| Memory across conversations | Yes (improving; auto-generated from history) | Yes (deep, automatic) |
+| Runs shell commands | No | Yes |
+| Code execution | Sandboxed (Artifacts) | Yes (full shell) |
+| Reads / writes files | Sandboxed (Artifacts) | Yes (full filesystem) |
+| Schedules background jobs | No | Yes |
+| Web UI | Yes | Yes |
+| Messaging apps | No | Yes |
+| Self-hosted | No | Yes |
+| Provider-agnostic | No | Yes |
+| Open source | No | Yes |
+
+---
+
+## The Compounding Advantage
+
+What matters most about Hermes is that it improves over time. That is the point.
+
+Every time Hermes encounters a new environment, it saves facts to memory. Every time it solves
+a problem a new way, it saves the approach as a skill. Every time you correct it, it updates its
+profile of you. Every session, every scheduled job, every tool call, the agent gets more
+calibrated to you and your workflow.
+
+A Claude Code session on day one and day one hundred are identical. A Hermes agent on day one
+and day one hundred is smarter about you -- it knows your stack, your conventions, your
+preferences, and the solutions that have worked before.
+
+---
+
+## Who Hermes Is For
+
+**Solo developers and power users** who don't want to re-explain their stack every session and
+want an AI that actually knows their environment.
+
+**Teams on a shared server** where multiple people want Claude-quality AI access without each
+paying for a separate subscription or running local tooling.
+
+**Automation-heavy workflows** where you want an AI running tasks on a schedule, delivering
+results to your phone, without babysitting it.
+
+**Privacy-conscious users** who want their conversations, memory, and files on their own
+hardware.
+
+**Multi-model users** who want to switch between OpenAI, Anthropic, Google, DeepSeek, and
+others based on cost, capability, or rate limits, without rebuilding their workflow each time.
+
+---
+
+## Scope and Limits
+
+**Hermes lives in the terminal, browser, and messaging apps.** For in-editor autocomplete and
+inline diffs, use Cursor or Windsurf alongside it -- they do that job better.
+
+**You run Hermes on your own server.** That means initial setup, but your data stays on your
+hardware and you control the schedule, the models, and the costs.
+
+**Hermes is an orchestration and memory layer.** It makes whatever model you point it at more
+useful over time. The models do the reasoning; Hermes makes sure that reasoning accumulates into
+something durable.

+
+This gives you nearly **1:1 parity with Hermes CLI from a convenient web UI** which you can access securely through an SSH tunnel from your Hermes setup. Single command to start this up, and a single command to SSH tunnel for access on your computer. Every single part of the web UI uses your existing Hermes agent and existing models, without requiring any additional setup.
+
+---
+
+## Why Hermes
+
+Most AI tools reset every session. They don't know who you are, what you worked on, or what
+conventions your project follows. You re-explain yourself every time.
+
+Hermes retains context across sessions, runs scheduled jobs while you're offline, and gets
+smarter about your environment the longer it runs. It uses your existing Hermes agent setup,
+your existing models, and requires no additional configuration to start.
+
+What makes it different from other agentic tools:
+
+- **Persistent memory** — user profile, agent notes, and a skills system that saves reusable
+  procedures; Hermes learns your environment and does not have to relearn it
+- **Self-hosted scheduling** — cron jobs that fire while you're offline and deliver results to
+  Telegram, Discord, Slack, Signal, email, and more
+- **10+ messaging platforms** — the same agent available in the terminal is reachable from your phone
+- **Self-improving skills** — Hermes writes and saves its own skills automatically from experience;
+  no marketplace to browse, no plugins to install
+- **Provider-agnostic** — OpenAI, Anthropic, Google, DeepSeek, OpenRouter, and more
+- **Orchestrates other agents** — can spawn Claude Code or Codex for heavy coding tasks and bring
+  the results back into its own memory
+- **Self-hosted** — your conversations, your memory, your hardware
+
+**vs. the field** *(landscape is actively shifting — see [HERMES.md](HERMES.md) for the full breakdown)*:
+
+| | OpenClaw | Claude Code | Codex CLI | OpenCode | Hermes |
+|---|---|---|---|---|---|
+| Persistent memory (auto) | Yes | Partial† | Partial | Partial | Yes |
+| Scheduled jobs (self-hosted) | Yes | No‡ | No | No | Yes |
+| Messaging app access | Yes (15+ platforms) | Partial (Telegram/Discord preview) | No | No | Yes (10+) |
+| Web UI (self-hosted) | Dashboard only | No | No | Yes | Yes |
+| Self-improving skills | Partial | No | No | No | Yes |
+| Python / ML ecosystem | No (Node.js) | No | No | No | Yes |
+| Provider-agnostic | Yes | No (Claude only) | Yes | Yes | Yes |
+| Open source | Yes (MIT) | No | Yes | Yes | Yes |
+
+† Claude Code has CLAUDE.md / MEMORY.md project context and rolling auto-memory, but not full automatic cross-session recall  
+‡ Claude Code has cloud-managed scheduling (Anthropic infrastructure) and session-scoped `/loop`; no self-hosted cron
+
+**The closest competitor is OpenClaw** — both are always-on, self-hosted, open-source agents
+with memory, cron, and messaging. The key differences: Hermes writes and saves its own skills
+automatically as a core behavior (OpenClaw's skill system centers on a community marketplace);
+Hermes is more stable across updates (OpenClaw has documented release regressions and ClawHub
+has had security incidents involving malicious skills); and Hermes runs natively in the Python
+ecosystem. See [HERMES.md](HERMES.md) for the full side-by-side.

+## Accessing on your phone with Tailscale
+
+[Tailscale](https://tailscale.com) is a zero-config mesh VPN built on
+WireGuard. Install it on your server and your phone, and they join the same
+private network -- no port forwarding, no SSH tunnels, no public exposure.
+
+The Hermes Web UI is fully responsive with a mobile-optimized layout
+(hamburger sidebar, bottom navigation bar, touch-friendly controls), so it
+works well as a daily-driver agent interface from your phone.
+
+**Setup:**
+
+1. Install [Tailscale](https://tailscale.com/download) on your server and
+   your iPhone/Android.
+2. Start the WebUI listening on all interfaces with password auth enabled:
+
+```bash
+HERMES_WEBUI_HOST=0.0.0.0 HERMES_WEBUI_PASSWORD=your-secret ./start.sh
+```
+
+3. Open `http://<server-tailscale-ip>:8787` in your phone's browser
+   (find your server's Tailscale IP in the Tailscale app or with
+   `tailscale ip -4` on the server).
+
+That's it. Traffic is encrypted end-to-end by WireGuard, and password auth
+protects the UI at the application level. You can add it to your home screen
+for an app-like experience.
+
+> **Tip:** If using Docker, set `HERMES_WEBUI_HOST=0.0.0.0` in your
+> `docker-compose.yml` environment (already the default) and set
+> `HERMES_WEBUI_PASSWORD`.

-## Sprint 18 -- Voice + Multimodal Input
+## Sprint 18 -- Thinking Display + Workspace Tree + Preview Fix (COMPLETED)
 
-**Theme:** Input beyond the keyboard.
+**Theme:** Show the model's reasoning, improve workspace navigation, fix UX bug.
 
-**Why now:** Voice is a meaningful quality-of-life feature for longer sessions
-and is achievable with Whisper. Image input closes the last modality gap with
-Claude (Claude accepts image paste natively -- we do too, but only as
-file uploads, not clipboard screenshots into the conversation directly).
+**Why now:** Thinking/reasoning display was deferred twice (Sprint 16 → 17 → 18).
+Workspace tree view was the #1 community request (Issue #22). File preview
+staying open on directory navigation was a daily-driver annoyance.
 
 ### Track A: Bugs
-- Image paste currently requires a click-to-attach flow. Direct paste into the
-  message textarea should embed the image inline (as a preview chip) and queue
-  it for upload on Send. (Partially works -- clean up edge cases.)
-- Large image uploads (>5MB) time out the upload step silently.
+- **File preview auto-close.** When viewing a file in the right panel and
+  navigating directories (breadcrumbs, up button, folder clicks), the preview
+  stayed visible with stale content. Fix: extracted `clearPreview()` as a named
+  function in boot.js and call it from `loadDir()` in workspace.js.
 
 ### Track B: Features
-- **Voice input (Whisper):** A microphone icon in the composer. Hold to record,
-  release to transcribe via `POST /api/transcribe` (calls local Whisper or
-  OpenAI Whisper API). Transcribed text appears in the message input, editable
-  before send. Supports the full "voice -> text -> Hermes response" loop.
-- **TTS playback:** A speaker icon on assistant messages. Calls a TTS endpoint
-  (ElevenLabs or OpenAI TTS) and plays the audio. Toggle per-message. Optional
-  auto-play mode in settings.
-- **Vision input improvements:** Paste a screenshot directly from clipboard into
-  the conversation (not just the tray). Shows as an inline preview chip with
-  the image thumbnail. On Send, uploads and includes in the message.
+- **Thinking/reasoning display.** Assistant messages with structured content
+  arrays containing `type:'thinking'` or `type:'reasoning'` blocks now render
+  as collapsible gold-themed cards above the response text. Collapsed by
+  default, click header to expand. Works with Claude extended thinking and
+  o3 reasoning tokens when preserved in the message array.
+- **Workspace tree view (Issue #22).** Directories expand/collapse in-place
+  with toggle arrows. Single-click toggles, double-click navigates (breadcrumb
+  view). Subdirectory contents fetched lazily and cached in `S._dirCache`.
+  Nesting depth shown via indentation. Empty directories show "(empty)".
+
+**Tests:** 0 new (pure CSS/DOM changes). Total: 318.
+**Hermes CLI parity impact:** Low
+**Claude parity impact:** High (reasoning display matches Claude's UI)
+
+---
+
+## Sprint 19 -- Auth + Security Hardening (COMPLETED)
+
+**Theme:** Make this safe to leave running beyond localhost.
+
+**Why now:** Issue #23 requested authentication. Auth is the last production
+hardening feature before the app is safe to expose to a network.
+
+### Track A: Bugs
+- **No request size limit.** POST bodies were unbounded (DoS risk). Added 20MB
+  cap in `read_body()`.
+
+### Track B: Features
+- **Password authentication (Issue #23).** Off by default — zero friction for
+  localhost. Enable via `HERMES_WEBUI_PASSWORD` env var or Settings panel.
+  Password-only (no username — single-user app). Signed HMAC HTTP-only cookie
+  with 24h TTL. Minimal dark-themed login page at `/login`. API calls without
+  auth return 401; page loads redirect to `/login`. Settings panel gains
+  "Access Password" field and "Sign Out" button.
+- **Security headers.** All responses now include `X-Content-Type-Options: nosniff`,
+  `X-Frame-Options: DENY`, `Referrer-Policy: same-origin`.
 
 ### Track C: Architecture
-- Audio pipeline: `POST /api/transcribe` streams audio bytes, returns transcript.
-  `GET /api/tts?text=...` returns audio/mpeg. Both use lazy import of Whisper
-  and TTS libraries to keep cold start fast.
+- New `api/auth.py` module: password hashing (SHA-256 + STATE_DIR salt), signed
+  session cookies, auth middleware, public path allowlist.
+- Auth check in `server.py` do_GET/do_POST before routing.
+- `password_hash` added to `_SETTINGS_DEFAULTS` in config.py.
+- `_set_password` special field in save_settings for secure password updates.
 
-**Tests:** ~12 new. Total: ~271.
+**Tests:** 10 new. Total: 328.
+**Hermes CLI parity impact:** Low (CLI has no auth concerns)
+**Claude parity impact:** High (Claude is authenticated)
+
+---
+
+## Sprint 20 -- Voice Input + Send Button Polish (COMPLETED)
+
+**Theme:** Input refinements — voice and visual polish.
+
+**Why now:** Voice input was the next feature on the roadmap. The send button
+UX was a low-effort high-impact polish opportunity that pairs naturally.
+
+### Track A: Bugs
+- **Send button always visible.** The old pill-shaped "Send" button was always
+  visible even with an empty textarea, wasting space. Now hidden by default,
+  appears only when there is content to send.
+
+### Track B: Features
+- **Voice input (Web Speech API).** Microphone button in composer. Tap to
+  record, tap again to stop. Live interim transcription in textarea. Auto-stops
+  after ~2s of silence. Appends to existing text. Hidden when browser doesn't
+  support Web Speech API. No API keys, no server changes.
+- **Send button polish.** Icon-only 34px circle with upward arrow SVG. Pop-in
+  spring animation on appear. Scale hover/active for tactile feedback. Hidden
+  while agent is responding.
+
+### Track C: Architecture
+- Voice input IIFE in `boot.js` with SpeechRecognition lifecycle.
+- `updateSendBtn()` in `ui.js` hooked into setBusy, renderTray, autoResize.
+
+**Tests:** 52 new (voice) + 33 new (send button). Total: 415.
 **Hermes CLI parity impact:** Medium (voice not in CLI, but adds capability)
 **Claude parity impact:** High (Claude has native voice mode)

-## Sprint 18 -- Subagent Visibility + Agentic Transparency
+## Sprint 21 -- Mobile Responsive + Docker (COMPLETED)
 
-**Theme:** Watch Hermes think, not just respond.
+**Theme:** Mobile experience + containerized deployment.
 
-**Why now:** When Hermes delegates to subagents (delegate_task, spawns parallel
-workstreams), the UI shows nothing. On long multi-agent tasks you have no idea
-what's happening. This is the last major "CLI feels better" gap for power users.
+**Why now:** Issue #21 (mobile) was the most-requested UX gap. Issue #7 (Docker)
+enables deployment beyond localhost. Both were achievable without new dependencies.
 
-### Track A: Bugs
-- Tool cards for delegate_task show no information about what the subagent was
-  asked to do or what it returned.
-- The activity bar text truncates at 55 chars -- tool previews for long terminal
-  commands show nothing useful.
+### Track A: Bugs (from review)
+- **CSS cascade broke mobile slide-in.** `position:relative` after the media query
+  overrode `position:fixed`. Wrapped in `@media(min-width:641px)`.
+- **mobileSwitchPanel() always reopened sidebar.** Chat tab now closes it.
+- **Dockerfile missing pip install.** Container failed on startup.
+- **No .dockerignore.** `.git`, `tests/`, `.env*` leaked into images.
+- **docker-compose tilde expansion.** `~` doesn't expand in Compose defaults.
 
 ### Track B: Features
-- **Subagent delegation cards:** When `delegate_task` fires, show an expandable
-  card with the subagent's goal, status (pending/running/done), and result
-  summary. Multiple subagents from one call appear as a card group. Uses the
-  existing tool card infrastructure.
-- **Background task monitor:** A "Tasks" indicator in the topbar (separate from
-  the cron Tasks panel). Shows count of active agent threads. Click opens a
-  popover listing all in-flight streams with session names and elapsed times.
-  Cancel any individual thread. This is the full job queue visibility the CLI
-  implicitly has via `ps aux`.
-- **Thinking/reasoning display:** When the model emits reasoning tokens (o3,
-  Claude extended thinking), show them in a collapsible "Reasoning" card above
-  the response. Collapsed by default. This matches Claude's reasoning display.
+- **Hamburger sidebar.** Slide-in overlay on mobile, tap outside to close.
+- **Bottom navigation bar.** 5-tab iOS-style bar replaces sidebar tabs.
+- **Files slide-over.** Right panel opens as slide-over from right edge.
+- **Touch targets.** Minimum 44px on all interactive elements.
+- **Docker support.** Dockerfile, docker-compose.yml, .dockerignore.
 
 ### Track C: Architecture
-- Task registry: extend STREAMS to include session name, start time, and task
-  description. New `GET /api/tasks/active` endpoint returns all running streams
-  with metadata.
+- Mobile nav functions in `boot.js`. Session click auto-closes sidebar.
+- 69 new CSS lines scoped to `@media(max-width:640px)`.
+- Desktop layout untouched — all mobile elements `display:none` by default.
 
-**Tests:** ~14 new. Total: ~285.
-**Hermes CLI parity impact:** Very High (subagent and task visibility is the
-  last major CLI gap)
-**Claude parity impact:** High (Claude shows reasoning, tool use visibly)
+**Tests:** 0 new (CSS/DOM changes). Total: 415.
+**Hermes CLI parity impact:** Low
+**Claude parity impact:** High (Claude has mobile layout)

-## Sprint 19 -- Auth, HTTPS, and Production Hardening
+## Sprint 22 -- Multi-Profile Support (COMPLETED, Issue #28)
 
-**Theme:** Make this safe to leave running.
+**Theme:** Switch between Hermes agent profiles seamlessly from the web UI.
 
-**Why now:** Everything else is done. This is the sprint you run when you want
-to expose the UI beyond localhost -- to a team, a mobile device, or a public
-address.
+**Why now:** Issue #28 requested full profile management in the UI. The CLI has
+had comprehensive profile support since v0.6.0 — isolated instances with their
+own config, skills, memory, cron, and API keys. The web UI was locked to a
+single default profile, blocking multi-persona workflows.
 
 ### Track A: Bugs
-- Server has no request size limit on non-upload endpoints (potential DoS).
-- Session JSON files have no size cap (a runaway agent could write GBs).
+- **Hardcoded `~/.hermes` paths.** Memory read/write in routes.py and model
+  discovery in config.py used hardcoded paths instead of the active profile's
+  directory. Fixed to resolve through `get_active_hermes_home()`.
+- **Module-level cached paths.** hermes-agent's `skills_tool.py` and `cron/jobs.py`
+  snapshot `HERMES_HOME` at import time. Profile switch now monkey-patches these
+  cached variables (`SKILLS_DIR`, `CRON_DIR`, `JOBS_FILE`, `OUTPUT_DIR`).
 
 ### Track B: Features
-- **Password authentication:** A login page with a configurable password
-  (HERMES_WEBUI_PASSWORD env var). Signed cookie session (24h expiry).
-  Single-user model -- no accounts, no registration.
-- **HTTPS / reverse proxy guide:** A one-page `DEPLOY.md` with instructions
-  for running behind nginx + Let's Encrypt on a VPS. Configuration snippets
-  for systemd service, nginx config, certbot.
-- **Mobile responsive layout:** Collapsible sidebar (hamburger). Touch-friendly
-  session list (swipe to delete, tap to navigate). Composer expands on focus.
-  Right panel hidden by default on mobile, accessible via a Files tab.
-- **Rate limiting:** Simple per-IP token bucket on the chat/start endpoint
-  (configurable, default 10 req/min) to prevent accidental hammering.
+- **Profile picker (topbar).** Purple-accented chip with SVG user icon in the
+  topbar. Click opens a dropdown listing all profiles with gateway status dots,
+  model info, and skill count. Click to switch; "Manage profiles" link opens
+  the management panel.
+- **Profiles sidebar panel.** New nav tab with full management UI. Cards show
+  each profile with model, provider, skill count, API key status, and gateway
+  badge. "Use" button to switch, delete button for non-default profiles.
+- **Profile creation.** "+ New profile" form with name validation (lowercase
+  alphanumeric + hyphens), optional "clone config from active" checkbox. Wraps
+  `hermes_cli.profiles.create_profile()`.
+- **Profile deletion.** Confirm dialog, auto-switches to default if deleting
+  the active profile. Blocked while agent is running.
+- **Seamless switching.** No server restart required. Profile switch updates
+  `HERMES_HOME` env var, patches module-level caches, reloads `.env` API keys,
+  reloads `config.yaml`, and refreshes the model dropdown, skills, memory, and
+  cron panels.
+- **Per-session profile tracking.** New `profile` field on Session records which
+  profile was active when the session was created. Backward-compatible (defaults
+  to `null` for old sessions).
 
 ### Track C: Architecture
-- Helmet headers: X-Content-Type-Options, X-Frame-Options, HSTS (when served
-  over HTTPS). Simple middleware in the Handler.
+- New `api/profiles.py` module (~200 lines): profile state management wrapping
+  `hermes_cli.profiles`. Thread-safe with `_profile_lock`. Lazy imports to
+  avoid circular dependencies.
+- `api/config.py`: Replaced module-level `cfg` dict with reloadable
+  `get_config()`/`reload_config()`. Dynamic `_get_config_path()` resolves
+  through active profile.
+- `api/streaming.py`: `HERMES_HOME` added to env save/restore block around
+  agent runs (alongside `TERMINAL_CWD`, `HERMES_EXEC_ASK`).
+- Profile switch blocked while any agent stream is active (process-global
+  `HERMES_HOME` cannot be changed mid-run).
+- Zero modifications to hermes-agent code required.
 
-**Tests:** ~12 new. Total: ~297.
-**Hermes CLI parity impact:** Low (CLI has no auth/HTTPS concerns)
-**Claude parity impact:** Very High (Claude is authenticated, HTTPS only)
+**Tests:** 0 new (profile management requires hermes-agent integration). Total: 415.
+**Hermes CLI parity impact:** Very High (profile support is a major CLI feature)
+**Claude parity impact:** Low (Claude has no profile concept)
+
+---
+
+## Sprint 23 -- Agentic Transparency + Context Visibility (COMPLETED)
+
+**Theme:** Surface what the agent is doing and how much context it's using.
+
+**Why now:** Users had no visibility into tool call arguments, session token
+usage, or context window fill. Sprint 22 left five coherence bugs in the
+profile/workspace/model flow that also needed closing before the UI felt
+reliable.
+
+### Track A: Bugs
+- **Model picker ignores profile on switch.** `populateModelDropdown()` skipped
+  the profile's default model if `localStorage` had a saved preference. Fixed:
+  `switchToProfile()` now clears `hermes-webui-model` from localStorage and
+  applies the profile's default model from the switch response.
+- **Workspace list is a global file.** `workspaces.json` was process-global.
+  Fixed: workspace storage is now profile-local at `{profile_home}/webui_state/`.
+  Default profile uses global STATE_DIR for backward compatibility.
+- **`DEFAULT_WORKSPACE` is a startup singleton.** Frozen at boot. Fixed:
+  `get_last_workspace()` and `_profile_default_workspace()` now resolve
+  dynamically through the active profile's config.
+- **Session list shows all profiles.** Fixed: `renderSessionListFromCache()`
+  filters to `S.activeProfile` by default, with "Show N from other profiles"
+  toggle (modeled on the archived toggle).
+- **`switchToProfile()` doesn't refresh workspace list or sessions.** Fixed:
+  now calls `loadWorkspaceList()`, `renderSessionList()`, resets profile filter.
+
+### Track B: Features
+- **Profile-local workspace storage.** Each named profile stores its own
+  `workspaces.json` and `last_workspace.txt` under `{profile_home}/webui_state/`.
+  Falls back to global STATE_DIR for the default profile (preserves test
+  isolation and backward compat).
+- **Profile switch returns defaults.** `POST /api/profile/switch` response now
+  includes `default_model` and `default_workspace` so the frontend can apply
+  both in one round-trip.
+- **Session profile filter.** Session sidebar filters to active profile by
+  default. "Show N from other profiles" toggle reveals sessions from all
+  profiles. Resets on profile switch.
+
+### Track C: Architecture
+- `api/workspace.py`: Rewritten with `_profile_state_dir()`, `_workspaces_file()`,
+  `_last_workspace_file()`, `_profile_default_workspace()`. All lazy imports to
+  avoid circular deps.
+- `api/profiles.py`: `switch_profile()` returns `default_model` and
+  `default_workspace` from the new profile's config.yaml.
+- `static/panels.js`: `switchToProfile()` clears localStorage model key,
+  refreshes workspace list and session list, resets profile filter.
+- `static/sessions.js`: `_showAllProfiles` state variable, profile filter in
+  `renderSessionListFromCache()`, toggle UI.
+
+**Tests:** 8 new (test_sprint23.py). Total: 423.
+**Hermes CLI parity impact:** High (coherent profile behavior)
+**Claude parity impact:** Low

+
+## Sprint 24 -- Web Polish + Bug Fix Pass (PLANNED)
+
+**Theme:** Stabilize, harden, and close the last meaningful web UI gaps before
+shifting focus to distribution. Goal is a release that's genuinely ready for
+wider user adoption -- no rough edges, no obvious missing pieces.
+
+**Why now:** Sprint 23 completed the core agentic transparency features. The
+remaining web roadmap items are diminishing-returns polish. Rather than
+grinding through marginal features, this sprint cleans up what's there, fixes
+bugs users will actually hit, and closes a few real gaps before recommending
+the app to others.
+
+### Track A: Bug Fixes
+- **Cron edit form has no skill picker.** Sprint 23 added skill picker to the
+  create form but not the edit form. cronEditSave() doesn't include skills in
+  the update body, so existing skills survive an edit but can't be changed.
+  Fix: add the same skill picker UI to the inline edit form and include
+  `skills` in the update POST body.
+- **S.lastUsage dead code.** messages.js sets `S.lastUsage` from `d.usage` at
+  done-time, but nothing reads it. The usage badge reads cumulative session
+  totals from `S.session.input_tokens` instead. Either wire `S.lastUsage` into
+  a per-turn display or remove the dead assignment.
+- **_cronSkillsCache never invalidated.** Skills picker shows stale data if
+  skills are added/removed mid-session. Add a cache-bust when the skills panel
+  is opened or a skill is saved/deleted.
+- **Tool args not shown on session reload.** Tool call cards in history show
+  name and result snippet but not the args (args only exist in the live SSE
+  event). Sprint 23 added args to the session JSON -- verify they're actually
+  rendering in the settled history cards.
+
+### Track B: Features
+- **Cron edit: skill picker parity.** As above -- make create and edit forms
+  identical in capability.
+- **Per-turn cost display.** The current usage badge shows cumulative session
+  totals attached to the last message, which is misleading. Either: (a) show
+  per-turn cost from `S.lastUsage` immediately after each response instead of
+  cumulative, or (b) show cumulative in the session topbar/header instead of
+  attached to a message bubble. Pick the cleaner UX.
+- **Virtual scroll for long session/skill lists.** When session count or skill
+  count gets large (100+), the sidebar becomes sluggish. Add a simple virtual
+  scroll or windowed render -- only render visible items + a buffer above/below.
+  CSS `contain: strict` + IntersectionObserver approach, no library needed.
+
+### Track C: Code Quality
+- Audit and remove any remaining dead code introduced by Sprint 23 (e.g. `S.lastUsage` assignment in messages.js that nothing reads).
+- Verify tool call args render correctly in settled history cards on session reload.
+- Update test count in all docs to match actual pytest output after sprint merges.
+
+**Estimated tests:** ~10 new. Target total: ~435.
+**Hermes CLI parity impact:** Low
+**Claude parity impact:** Low
+**User-facing value:** Medium -- removes rough edges that would bother new users
+
+---
+
+## Sprint 25 -- macOS Desktop Application (PLANNED)
+
+**Theme:** Native Mac desktop app. Single download, runs entirely offline,
+feels like a real application -- not a browser tab.
+
+**Why this matters:** The web UI requires an SSH tunnel or a server setup to
+use. A .app bundle that a user can double-click and immediately have a working
+Hermes interface is genuinely differentiating. No other open-source Hermes
+interface ships as a native Mac app. This is the highest-leverage remaining
+investment for user adoption.
+
+**Approach: Swift + WKWebView (not Electron)**
+
+The right architecture is a thin native Swift shell (~300-500 lines) that:
+1. Bundles the existing Python server and all api/ modules inside the .app
+2. Spawns the server as a subprocess on a random local port at launch
+3. Opens a WKWebView window pointed at that localhost port
+4. Handles Mac app lifecycle natively (dock icon, cmd+Q, window management,
+   app menu, about box)
+5. Bridges a small set of native Mac capabilities that WKWebView can't do
+
+**Why not Electron:** WKWebView is Safari's engine -- dramatically lighter than
+Chromium. No 200MB node_modules. No separate update daemon. The .app is ~30MB
+including the Python runtime, vs 150MB+ for Electron.
+
+**Why not full native Swift UI:** Would require rewriting the entire frontend
+from scratch. The web UI is already fast, dark-themed, and feature-complete.
+The thin shell approach gets 95% of the benefit at 5% of the cost.
+
+### Track A: Swift App Shell
+
+**Files to create:**
+```
+desktop/
+  HermesApp.swift          -- @main entry point, NSApp delegate
+  AppDelegate.swift        -- lifecycle: start server on launch, stop on quit
+  WindowController.swift   -- NSWindow + WKWebView setup, cmd shortcuts
+  ServerManager.swift      -- spawn/monitor Python subprocess, pick free port
+  MenuBuilder.swift        -- native app menu (File, Edit, View, Window, Help)
+  Info.plist               -- bundle ID, display name, version, icon
+  Assets.xcassets/         -- app icon (1024x1024 + all required sizes)
+  HermesApp.xcodeproj/     -- Xcode project file
+```
+
+**ServerManager.swift responsibilities:**
+- Find Python: check bundled runtime first, fall back to system python3
+- Pick a free port (bind to :0, read assigned port, close, use it)
+- Spawn: `python3 server.py --port {port}` as a child Process
+- Monitor: if server crashes, show an error sheet and offer restart
+- Shutdown: SIGTERM on app quit, wait up to 3s, then SIGKILL
+
+**WKWebView configuration:**
+- `allowsBackForwardNavigationGestures = false` (it's a single-page app)
+- `WKUserContentController` for JS bridge (native notifications, file picker)
+- Wait for server health check before loading (poll /health, show loading
+  spinner in the native window while waiting, typically <1s)
+- `userAgent` override so the server can detect desktop app context
+
+**Native menu items (beyond defaults):**
+- File > New Session (Cmd+N) -- calls JS `newSession()`
+- File > New Window (Cmd+Shift+N) -- opens second window with its own WKWebView
+- View > Toggle Sidebar (Cmd+Shift+S)
+- Window > Zoom, Minimize (standard)
+- Help > About Hermes, Check for Updates (links to GitHub releases page)
+
+### Track B: Python Bundling
+
+Two options, in order of preference:
+
+**Option A: Require system Python (simpler, recommended for v1)**
+- Check for `python3` at known paths: `/usr/bin/python3`, homebrew paths,
+  pyenv paths
+- If not found: show a one-time setup sheet with instructions
+- Pros: tiny download (~5MB for the Swift app + web assets), no bundling complexity
+- Cons: user needs Python installed (most developers do; target audience does too)
+
+**Option B: Bundle python-standalone (self-contained, larger)**
+- Use `python-build-standalone` (from Astral/uv project): pre-built Python
+  3.11 binaries, ~30MB compressed, no Xcode toolchain needed to build
+- Extract to `~/Library/Application Support/Hermes/python/` on first launch
+- Install `requirements.txt` via bundled pip into a local venv
+- Pros: zero dependencies, works on a clean Mac
+- Cons: first launch takes ~10-20s for extraction + pip install; ~30MB download
+
+**Recommendation:** Ship v1 with Option A. Add Option B as an optional
+"standalone" download for non-developers.
+
+### Track C: Distribution
+
+**GitHub Releases (primary):**
+- Build with `xcodebuild -scheme HermesApp -configuration Release -archivePath`
+- `xcodebuild -exportArchive` to produce a .app bundle
+- `hdiutil create` to produce a .dmg with drag-to-Applications installer UI
+- Upload .dmg as a GitHub Release asset via `gh release create`
+- CI: add `.github/workflows/mac-release.yml` -- trigger on `vX.Y.Z-mac` tag
+
+**Code signing:**
+- Without an Apple Developer account: distribute as unsigned, users must
+  right-click > Open on first launch (standard for open-source Mac apps)
+- With a free Apple Developer account: ad-hoc signing removes the Gatekeeper
+  warning without paying $99/year (no notarization, but much better UX)
+- With paid account ($99/year): full notarization, no warnings, direct download
+
+**Recommended for v1:** ad-hoc signing (free, good enough for early adopters).
+Document the right-click > Open workaround in the README for unsigned builds.
+
+**Universal binary (Intel + Apple Silicon):**
+```bash
+xcodebuild archive -scheme HermesApp -destination "generic/platform=macOS"
+```
+Both architectures in one .app. No separate downloads needed.
+
+### Track D: Native Integrations (v1 scope)
+
+**System notifications for cron completion:**
+- The web UI polls `/api/cron/alerts` and shows in-page banners
+- The Mac app can additionally post `UNUserNotificationCenter` notifications
+- JS bridge: `window.webkit.messageHandlers.notify.postMessage({title, body})`
+- Swift handler: posts a native notification with the cron job name and output
+  summary -- appears in Notification Center, works even when app is in background
+
+**File picker for workspace add:**
+- Currently: user types a path string into the workspace add form
+- Mac app: intercept workspace-add form submission, open `NSOpenPanel` instead,
+  return the selected path to the JS via `evaluateJavaScript`
+- Much better UX -- standard Mac folder picker, no typing paths
+
+**Dock badge for pending approvals:**
+- When an agent approval is waiting, set `NSApp.dockTile.badgeLabel = "1"`
+- Clear badge when approval is resolved
+- JS bridge fires when approval card appears/disappears
+
+**Menu bar mode (optional, v2):**
+- A small status bar item (⚗️ icon in menu bar) that opens a compact popover
+- Popover shows current session status, last message, quick-compose field
+- Useful for running Hermes in the background without a full window
+
+### Track E: Testing
+
+Since the Swift app is thin glue, most testing remains in the existing pytest
+suite (server still runs identically). New Swift-specific tests:
+- `ServerManagerTests.swift`: verify port picking, process spawn, health wait
+- UI tests via `XCUITest`: launch app, wait for WKWebView to load, verify
+  title bar shows "Hermes", verify /health responds
+- Smoke test in CI: `xcodebuild test -scheme HermesApp`
+
+### Implementation Order
+
+1. `ServerManager.swift` + basic `AppDelegate` -- get Python server spawning
+   and health-check working from Swift
+2. `WindowController.swift` -- WKWebView loading, loading spinner while
+   server starts
+3. App icon + Info.plist -- make it look like a real app
+4. `MenuBuilder.swift` -- native menus + keyboard shortcuts
+5. JS bridge for notifications -- most impactful native integration
+6. DMG build script + GitHub Actions CI
+7. (Optional) File picker bridge, dock badge
+
+### What to NOT do in v1
+
+- Windows or Linux wrapper (different toolchain; do Mac first, assess demand)
+- Full Swift/SwiftUI rewrite of the frontend (months of work, wrong tradeoff)
+- App Store submission (sandboxing breaks local server; not worth the effort)
+- Auto-update mechanism (GitHub releases + manual download is fine for v1)
+- Menu bar mode (cool but not v1 scope)
+
+### Files to create in the repo
+
+```
+desktop/mac/
+  HermesApp/
+    HermesApp.swift
+    AppDelegate.swift
+    WindowController.swift
+    ServerManager.swift
+    MenuBuilder.swift
+    Assets.xcassets/
+    Info.plist
+  HermesApp.xcodeproj/
+  README.md              -- build instructions, requirements, signing notes
+.github/workflows/
+  mac-release.yml        -- build + sign + upload DMG on tag push
+```
+
+The server code (`server.py`, `api/`, `static/`, `requirements.txt`) is
+referenced from the repo root -- no duplication. The .app bundle copies them
+at build time.
+
+**Estimated effort:** 2-3x a typical web sprint (new language, new toolchain,
+bundling complexity). Realistic for a focused weekend or a dedicated agent run
+with clear instructions.
+
+**Hermes CLI parity impact:** N/A (different distribution channel)
+**Claude parity impact:** Medium (Claude.app is a native Mac app)
+**User-facing value:** Very high -- lowers barrier to entry dramatically,
+genuinely differentiating for an open-source project

+## Sprint 26 -- Pluggable UI Themes (COMPLETED)
+
+**Theme:** Let users choose how the app looks -- light, dark, and custom color
+schemes. One-click switching, persistent preference, zero flicker on load.
+
+**Difficulty: Low-Medium.** The existing CSS is already 100% CSS-variable-driven
+off a single `:root` block. Every color, background, and accent in the entire UI
+is already a variable. Adding themes is mostly a matter of defining alternative
+`:root` overrides and wiring a picker -- not a rewrite. The main engineering
+work is flicker prevention on load and the settings UI.
+
+**Estimated effort:** 1 sprint, ~2 days of implementation. 8-12 new tests.
+
+---
+
+### Why now
+
+The UI ships only one dark theme. Contributors have asked for light mode. Power
+users want to match their terminal colorscheme. This is low-risk, high-value
+polish that makes the app feel more finished and more personal. It's also a
+good precedent-setter: once the theme system exists, community members can
+contribute new themes as a pure CSS addition with no Python changes needed.
+
+---
+
+### Design decisions
+
+**Themes are CSS-variable overrides, not separate stylesheets.** Each theme is
+a named `:root[data-theme="name"]` block. The base stylesheet stays untouched.
+Switching themes sets `document.documentElement.dataset.theme = name` in JS.
+No FOUC (flash of unstyled content), no stylesheet swap latency.
+
+**Theme preference persists server-side in `settings.json`.** Same mechanism
+as `send_key` and `show_token_usage`. The server includes `theme` in the
+`GET /api/settings` response. Boot.js reads it and applies before first paint.
+
+**Flicker prevention.** A tiny inline `<script>` in `<head>` (before the
+stylesheet link) reads `localStorage.getItem('hermes-theme')` and sets
+`document.documentElement.dataset.theme` synchronously. This prevents a
+dark-flash on light-mode users during the round-trip to `/api/settings`.
+The localStorage value is kept in sync whenever the user changes themes.
+
+**No third-party dependencies.** Pure CSS + vanilla JS. No theme library.
+
+---
+
+### Track A: Core theme system
+
+**1. CSS variable blocks in `static/style.css`**
+
+The existing `:root` block becomes the `dark` (default) theme. Add named
+theme blocks immediately after:
+
+```css
+/* ── Default (dark) theme ── already in :root ── */
+
+:root[data-theme="light"] {
+  --bg: #f5f5f7;
+  --sidebar: #e8e8ed;
+  --border: rgba(0,0,0,0.10);
+  --border2: rgba(0,0,0,0.16);
+  --text: #1c1c1e;
+  --muted: #6e6e80;
+  --accent: #c0392b;
+  --blue: #0a6dc2;
+  --gold: #a07a20;
+  --code-bg: #f0f0f5;
+}
+
+:root[data-theme="solarized"] {
+  --bg: #002b36;
+  --sidebar: #073642;
+  --border: rgba(255,255,255,0.08);
+  --border2: rgba(255,255,255,0.13);
+  --text: #839496;
+  --muted: #657b83;
+  --accent: #dc322f;
+  --blue: #268bd2;
+  --gold: #b58900;
+  --code-bg: #073642;
+}
+
+:root[data-theme="monokai"] {
+  --bg: #272822;
+  --sidebar: #1e1f1c;
+  --border: rgba(255,255,255,0.07);
+  --border2: rgba(255,255,255,0.12);
+  --text: #f8f8f2;
+  --muted: #75715e;
+  --accent: #f92672;
+  --blue: #66d9e8;
+  --gold: #e6db74;
+  --code-bg: #1e1f1c;
+}
+
+:root[data-theme="nord"] {
+  --bg: #2e3440;
+  --sidebar: #272c36;
+  --border: rgba(255,255,255,0.07);
+  --border2: rgba(255,255,255,0.12);
+  --text: #eceff4;
+  --muted: #9099aa;
+  --accent: #bf616a;
+  --blue: #81a1c1;
+  --gold: #ebcb8b;
+  --code-bg: #272c36;
+}
+```
+
+Additional theming notes:
+- `syntax-highlight` colors (Prism.js) are theme-independent (they come from the
+  CDN stylesheet) -- acceptable for v1.
+- The logo gradient (`linear-gradient(145deg,#e8a030,var(--accent))`) uses
+  `--accent` already so it adapts automatically.
+- Scrollbar colors and `::selection` backgrounds need explicit overrides in the
+  light theme to avoid dark scrollbars on a light background.
+
+**2. Flicker-prevention inline script in `static/index.html`**
+
+Immediately after `<head>` opens, before the stylesheet `<link>`:
+
+```html
+<script>
+(function(){
+  var t=localStorage.getItem('hermes-theme');
+  if(t && t!=='dark') document.documentElement.dataset.theme=t;
+})();
+</script>
+```
+
+This runs synchronously before the stylesheet parses. Zero flicker.
+
+**3. Theme loading in `static/boot.js`**
+
+In the existing `api('/api/settings')` call, read and apply the theme:
+
+```js
+const s = await api('/api/settings');
+window._sendKey = s.send_key || 'enter';
+window._showTokenUsage = !!s.show_token_usage;
+window._showCliSessions = !!s.show_cli_sessions;
+// Theme: apply server preference, update localStorage for flicker prevention
+const theme = s.theme || 'dark';
+document.documentElement.dataset.theme = theme;
+localStorage.setItem('hermes-theme', theme);
+```
+
+**4. Theme setting in `api/config.py`**
+
+```python
+_SETTINGS_DEFAULTS = {
+    ...
+    'theme': 'dark',  # active UI theme name
+    ...
+}
+_SETTINGS_ALLOWED_KEYS = set(_SETTINGS_DEFAULTS.keys()) - {'password_hash'}
+```
+
+No enum constraint on `theme` -- allows user-defined theme names to work
+without server changes.
+
+---
+
+### Track B: Theme picker UI
+
+**Settings panel addition (`static/index.html` + `static/panels.js`)**
+
+A `<select>` in the Settings panel, below the send-key picker:
+
+```html
+<div class="settings-field">
+  <label for="settingsTheme">Theme</label>
+  <select id="settingsTheme" ...>
+    <option value="dark">Dark (default)</option>
+    <option value="light">Light</option>
+    <option value="solarized">Solarized Dark</option>
+    <option value="monokai">Monokai</option>
+    <option value="nord">Nord</option>
+  </select>
+</div>
+```
+
+In `loadSettingsPanel()`:
+```js
+const themeSel = $('settingsTheme');
+if(themeSel) themeSel.value = settings.theme || 'dark';
+```
+
+In `saveSettings()`:
+```js
+body.theme = $('settingsTheme').value;
+```
+
+**Live preview on select change (no save required):**
+```js
+$('settingsTheme').addEventListener('change', e => {
+  document.documentElement.dataset.theme = e.target.value;
+  localStorage.setItem('hermes-theme', e.target.value);
+});
+```
+
+This gives instant visual feedback as the user clicks through options.
+The full settings save then persists it server-side.
+
+**`/theme` slash command (`static/commands.js`)**
+
+```js
+async function cmdTheme(arg) {
+  const themes = ['dark','light','solarized','monokai','nord'];
+  if(!arg || !themes.includes(arg)) {
+    showToast('Usage: /theme dark|light|solarized|monokai|nord');
+    return;
+  }
+  document.documentElement.dataset.theme = arg;
+  localStorage.setItem('hermes-theme', arg);
+  try { await api('/api/settings', {method:'POST', body: JSON.stringify({theme: arg})}); } catch(e) {}
+  showToast('Theme: ' + arg);
+}
+```
+
+---
+
+### Track C: Tests
+
+New test cases in `tests/test_sprint26.py`:
+
+1. `GET /api/settings` returns `theme: 'dark'` by default
+2. `POST /api/settings` with `{theme: 'light'}` persists and round-trips
+3. `POST /api/settings` with `{theme: 'nord'}` accepts any string (no enum gate)
+4. Theme value survives server restart (reads from `settings.json`)
+5. `/theme` command fires without error for each named theme
+6. `loadSettingsPanel()` populates the select with the current theme value
+7. Settings save includes theme in the POST body
+8. `data-theme` attribute is set on `<html>` before first paint (inline script)
+
+**Estimated new tests:** 8. Target total after sprint: ~443.
+
+---
+
+### What's out of scope
+
+- **Custom color editors** (hex pickers for each variable): saves that for v2.
+  The five shipped themes cover the main use cases. A custom theme can always
+  be added by dropping a CSS block with no code changes.
+- **Per-session themes**: single global preference is the right call for v1.
+- **System `prefers-color-scheme` sync**: nice-to-have, low priority. The
+  flicker-prevention script could be extended to read the media query if no
+  explicit preference is set.
+- **Prism.js theme switching**: the code-block syntax highlighting comes from
+  a CDN stylesheet. Swapping it requires a `<link>` swap and SRI re-check.
+  Defer to a future sprint; the default Prism Tomorrow theme works on all
+  current dark themes and is acceptable on light.
+
+---
+
+**Estimated tests:** 8 new. Target total: ~443.
+**Hermes CLI parity impact:** None
+**Claude parity impact:** Medium (Claude.ai has light/dark/system sync)
+**User-facing value:** High -- first thing many users ask for

+## Sections Added Post-Sprint 10 (Sprints 11-19)
+
+The following features were added in Sprints 11-19 and need manual browser testing.
+Each has automated API-level tests in `tests/test_sprint{N}.py`.
+
+### Sprint 11: Multi-Provider Models
+- Open model dropdown. Verify models grouped by provider (OpenAI, Anthropic, Google, etc.)
+- If custom `base_url` configured in config.yaml, verify local models appear in dropdown.
+- Switch model. Send a message. Verify response uses selected model.
+
+### Sprint 12: Settings + Pin + Import
+- Click gear icon. Settings overlay opens.
+- Change default model, save. Restart server. Verify setting persisted.
+- Pin a session (star icon in hover overlay). Verify it floats to top of list.
+- Export session as JSON. Import it back. Verify messages restored.
+
+### Sprint 13: Alerts + Session QoL
+- Duplicate a session (copy icon in hover overlay). Verify "(copy)" title.
+- Browser tab title updates to active session name. Switch sessions — title changes.
+
+### Sprint 14: Visual Polish + Workspace Ops
+- Create a mermaid code block in a response. Verify diagram renders inline.
+- Message timestamps visible next to role labels (hover for full date).
+- Double-click a file in workspace panel to rename. Enter saves, Escape cancels.
+- Create a folder via folder icon in workspace header.
+- Add `#tag` to session title. Verify tag chip appears in sidebar. Click to filter.
+- Archive a session. Verify it disappears. Toggle "Show archived" to see it.
+
+### Sprint 15: Session Projects
+- Click "+" in project bar to create a project. Type name, Enter.
+- Click a project chip to filter sessions.
+- Hover a session → click folder icon → assign to project via picker.
+- Verify colored left border appears on assigned session.
+- Double-click project chip to rename. Right-click to delete.
+- Code blocks have a "Copy" button. Click → "Copied!" feedback.
+- Messages with 2+ tool cards show "Expand all / Collapse all" toggle.
+
+### Sprint 16: Sidebar Visual Polish
+- Session titles use full sidebar width (no truncated space for hidden icons).
+- Hover a session → action buttons appear from right with gradient fade.
+- All icons are monochrome SVGs (not emoji). Consistent across platforms.
+- Pinned sessions show small gold star inline. Unpinned = no star, full title width.
+- Active session has gold highlight (not blue). Overlay gradient matches.
+- Double-click to rename → overlay hides during rename.
+
+### Sprint 17: Workspace + Slash Commands + Send Key
+- Navigate into a subdirectory. Breadcrumb bar appears with clickable segments.
+- Up button in panel header navigates to parent. Hidden at root.
+- Type `/` in composer → autocomplete dropdown appears. Arrow keys navigate.
+- Type `/help` → lists all commands. `/clear` clears conversation. `/model` switches.
+- Settings panel: change send key to Ctrl+Enter. Verify Enter inserts newline.
+
+### Sprint 18: Thinking + Tree View + Preview Fix
+- View a file in workspace. Click a breadcrumb or folder → preview closes automatically.
+- Click a directory toggle arrow (▸) → expands in-place showing children.
+- Click again (▾) → collapses. Double-click navigates into it (breadcrumb view).
+- If model returns thinking blocks (Claude extended thinking), verify collapsible gold card appears above response.
+
+### Sprint 19: Auth + Security
+- No password set: everything works as normal. No login page.
+- Set `HERMES_WEBUI_PASSWORD=test` env var. Restart. All pages redirect to `/login`.
+- Login page: minimal card, password field, "Sign in" button.
+- Enter correct password → redirected to `/`. Cookie set (24h).
+- Enter wrong password → error message, stay on login page.
+- Settings panel: set password via "Access Password" field. Auth activates.
+- "Sign Out" button visible when auth active. Click → redirected to /login.
+- API calls without auth cookie → 401 JSON response.
+- Check response headers: `X-Content-Type-Options: nosniff`, `X-Frame-Options: DENY`.
+
+### Sprint 20: Voice Input + Send Button
+- Mic button visible in composer (Chrome/Edge). Hidden in Firefox.
+- Tap mic → button turns red with pulse, "Listening..." indicator appears.
+- Speak → live transcription appears in textarea.
+- Stop speaking → auto-stops after ~2s silence. Text stays editable.
+- Tap mic again or Send → stops recording, sends text.
+- Type text, then tap mic → spoken text appends to existing text (doesn't replace).
+- Send button hidden when textarea is empty. Appears with pop-in animation when typing.
+- Send button is icon-only circle (no "Send" text label). Blue with glow.
+- Attach a file with no text → send button appears.
+- Send message → button disappears after textarea clears.
+- While agent is responding → send button hidden.
+
+### Sprint 21: Mobile Responsive + Docker
+- Open on mobile viewport (<640px): hamburger icon visible in topbar.
+- Tap hamburger → sidebar slides in from left with backdrop overlay.
+- Tap outside sidebar → closes. Tap a session → closes and loads session.
+- Bottom navigation bar: 5 tabs (Chat, Tasks, Skills, Memory, Spaces).
+- Tap "Tasks" in bottom nav → sidebar opens showing Tasks panel.
+- Tap "Chat" in bottom nav → sidebar closes (chat is in main area).
+- Files button in topbar → right panel slides in from right.
+- All touch targets are at least 44px (session items, buttons, icons).
+- Desktop viewport (>640px): no hamburger, no bottom nav, no mobile elements.
+- Docker: `docker compose up -d` starts server on port 8787.
+- Docker: session data persists across container restarts (named volume).
+
+### Sprint 22: Multi-Profile Support
+- Profile chip in topbar (purple accent). Click → dropdown with all profiles.
+- Dropdown shows gateway status dots, model info, skill count per profile.
+- Click a profile → switches; model dropdown, skills, memory, cron refresh.
+- "Manage profiles" link opens Profiles sidebar panel.
+- Profiles panel: cards with name, model, provider, skill count, API key status.
+- "Use" button switches profile. Delete button removes non-default profiles.
+- "+ New profile" form: name validation (lowercase + hyphens), clone config checkbox.
+- Create profile → appears in list and dropdown.
+- Delete profile → confirm dialog. Auto-switches to default if deleting active.
+- Attempt switch while agent busy → blocked with toast message.
+- With hermes-agent not installed → only default profile shown, graceful fallback.

+# Hermes Web UI — Themes
+
+Hermes Web UI supports pluggable color themes. Seven themes ship built-in, and
+you can create your own with pure CSS — no Python changes needed.
+
+---
+
+## Switching Themes
+
+**Settings panel:** Click the gear icon, select a theme from the dropdown. The
+preview is instant — the UI updates as you click through options.
+
+**Slash command:** Type `/theme dark` or `/theme light` in the composer.
+
+**Themes persist** across page reloads and server restarts (stored in
+`settings.json` server-side, with `localStorage` for flicker-free loading).
+
+---
+
+## Built-in Themes
+
+| Theme | Description |
+|-------|-------------|
+| **Dark** (default) | Deep navy/indigo with muted blue accents. Easy on the eyes for long sessions. |
+| **Light** | Warm off-white with dark text. High contrast for bright environments. |
+| **Slate** | Warm charcoal, lighter than Dark. Easier on the eyes for extended use. |
+| **Solarized Dark** | Ethan Schoonover's classic dark palette. Teal background, warm accents. |
+| **Monokai** | Warm dark theme inspired by the Monokai editor scheme. Green/pink accents. |
+| **Nord** | Arctic blue-gray palette from the Nord color system. Calm and minimal. |
+| **OLED** | True black (#000) backgrounds for OLED displays. Minimizes glow and burn-in risk. |
+| **Custom themes** | Any string accepted by `settings.json`, `POST /api/settings`, and `/theme` if added to the picker/command list. Pure CSS variables only. |
+
+---
+
+## Creating a Custom Theme
+
+A theme is a CSS block that overrides the color variables. Add it to
+`static/style.css` (or a separate file that you link after the main stylesheet).
+
+### Step 1: Define your theme block
+
+Every color in the UI comes from these CSS variables:
+
+```css
+:root[data-theme="your-theme-name"] {
+  /* Core palette */
+  --bg: #1a1a2e;          /* Main background */
+  --sidebar: #16213e;      /* Sidebar background */
+  --border: rgba(255,255,255,0.08);   /* Subtle borders */
+  --border2: rgba(255,255,255,0.14);  /* Stronger borders */
+  --text: #e8e8f0;         /* Primary text color */
+  --muted: #8888aa;        /* Secondary/muted text */
+  --accent: #e94560;       /* Accent color (errors, warnings, delete) */
+  --blue: #7cb9ff;         /* Primary action color (links, active states) */
+  --gold: #c9a84c;         /* Secondary accent (pinned items, gold highlights) */
+  --code-bg: #0d1117;      /* Code block background */
+
+  /* Surface and chrome (required for full theme polish) */
+  --surface: #1a2535;      /* Dropdowns, popups, toast, approval card */
+  --topbar-bg: rgba(22,33,62,.98);   /* Topbar background */
+  --main-bg: rgba(26,26,46,0.5);    /* Main chat area background */
+  --input-bg: rgba(255,255,255,.04); /* Input/button subtle backgrounds */
+  --hover-bg: rgba(255,255,255,.06); /* Hover state backgrounds */
+  --focus-ring: rgba(124,185,255,.35); /* Focus border color */
+  --focus-glow: rgba(124,185,255,.08); /* Focus box-shadow glow */
+
+  /* Typography (required for readable text across themes) */
+  --strong: #fff;          /* Bold text in messages */
+  --em: #c9c9e8;           /* Italic text in messages */
+  --code-text: #f0c27f;    /* Inline code text color */
+  --code-inline-bg: rgba(0,0,0,.35); /* Inline code background */
+  --pre-text: #e2e8f0;     /* Code block text color */
+}
+```
+
+The **core palette** controls the overall mood. The **surface/chrome** and
+**typography** variables are part of the standard theme contract — define all
+of them for a complete theme.
+
+For **light themes**, you also need `:root[data-theme="name"]` overrides
+for elements that use `rgba(255,255,255,.XX)` hover/border effects (these
+are invisible on light backgrounds). See the built-in light theme for the
+full pattern — it overrides ~45 selectors for proper dark-on-light contrast
+on hover states, borders, chips, role labels, session items, and
+interactive elements.
+
+### Step 2: Add it to the theme picker (optional)
+
+To make your theme appear in the Settings dropdown, add an `<option>` to the
+theme `<select>` in `static/index.html`:
+
+```html
+<option value="your-theme-name">Your Theme Name</option>
+```
+
+And update the `/theme` command's valid theme list in `static/commands.js`.
+
+### Step 3: Test it
+
+Switch to your theme via `/theme your-theme-name` or the Settings panel.
+Check these areas:
+- Sidebar session list (hover states, active state, project borders)
+- Message bubbles (user vs assistant styling)
+- Code blocks (background contrast, copy button visibility)
+- Tool cards (running indicator, expand/collapse)
+- Settings panel and login page
+- Mobile layout (hamburger sidebar, bottom nav)
+
+### Tips
+
+- **Light themes** need scrollbar and selection overrides, plus the full
+  text/code set (`--strong`, `--em`, `--code-text`, `--code-inline-bg`,
+  `--pre-text`) or they will look broken.
+- The **logo gradient** uses `--accent` automatically, so it adapts to your
+  theme without extra work.
+- **Prism.js syntax highlighting** uses its own CDN stylesheet (Tomorrow theme).
+  It works well on dark themes; on light themes the contrast is acceptable but
+  not perfect. Custom Prism theme support is planned for a future update.
+- **No server changes needed.** The `theme` setting in `settings.json` accepts
+  any string — your custom theme name will persist without code changes.
+
+---
+
+## How Themes Work Internally
+
+1. Each theme is a `:root[data-theme="name"]` CSS block that overrides variables.
+2. Switching themes sets `document.documentElement.dataset.theme = name` in JS.
+3. A tiny inline `<script>` in `<head>` reads `localStorage` before the
+   stylesheet loads — this prevents a flash of the wrong theme on page load.
+4. The theme preference is saved server-side via `POST /api/settings` and
+   loaded on boot via `GET /api/settings`.
+5. The `/theme` command and Settings dropdown both update the DOM, localStorage,
+   and server settings simultaneously.
+
+---
+
+## Contributing a Theme
+
+To contribute a new built-in theme:
+
+1. Add your `:root[data-theme="name"]` block to `static/style.css`
+2. Add the `<option>` to the Settings panel in `static/index.html`
+3. Add the theme name to the valid list in `cmdTheme()` in `static/commands.js`
+4. Test on desktop and mobile
+5. Open a PR — themes are pure CSS additions with no backend changes needed

+  2. Login rate limiting — 5th attempt 429, 6th rejected, still works after burst
+  3. Session ID validation — non-hex chars rejected in Session.load()
+  4. Error path sanitization — _sanitize_error() strips filesystem paths
+  5. Secure cookie detection — getattr used safely on plain socket
+  6. HMAC signature length — 32-char hex (128-bit), not 16
+  7. Skills path traversal — path outside SKILLS_DIR rejected
+  8. Content-Disposition for dangerous MIME types — HTML/SVG force download
+  9. PBKDF2 password hashing — save_settings uses auth._hash_password
+  10. Non-loopback startup warning (manual / integration test)
+  11. SSRF DNS check logic (unit test on helper function)
+  12. ENV_LOCK export — _ENV_LOCK importable from streaming module
