+## [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 `'` (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.
+- Profile switch blocked while agent streams are active.
+- 5 new API endpoints: `GET /api/profiles`, `GET /api/profile/active`,
+  `POST /api/profile/switch`, `POST /api/profile/create`,
+  `POST /api/profile/delete`.
+- Zero modifications to hermes-agent code.

+## [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.

-## 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 -- Profile/Workspace/Model Coherence (COMPLETED)
+
+**Theme:** Make profiles, workspaces, models, and sessions coherent across
+profile switches.
+
+**Why now:** Sprint 22 added profile switching but five coherence bugs remained:
+the model picker ignored the profile's default, workspaces were a global file,
+DEFAULT_WORKSPACE was a startup singleton, the session list showed all profiles,
+and switchToProfile() didn't refresh workspaces or sessions.
+
+### 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
+- **SPRINTS.md + ROADMAP.md + CHANGELOG.md updated** to reflect Sprint 23
+  completion (agentic transparency) and correct test counts.
+- **Remove stale Sprint 23 description** from SPRINTS.md (the "Profile/Workspace
+  coherence" text is from an older plan; Sprint 23 actually shipped agentic
+  transparency features).
+- **CHANGELOG entry for v0.29** covering Sprint 23 deliverables.
+
+**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

+## 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.
