dfb561a3ae refactor(desktop+dashboard): extract shared WebSocket/JSON-RPC layer 
The Electron desktop app and the web dashboard each carried their own
copy of the tui_gateway JSON-RPC WebSocket client plus near-identical
auth'd WS-URL construction. The dashboard's copy was the historical
source of the "is the dashboard required to run the desktop app?"
confusion, since the two surfaces looked coupled.

Consolidate the genuinely shared transport into the existing
framework-agnostic `@hermes/shared` package so both surfaces consume it
independently — neither app depends on the other:

- Move `resolveGatewayWsUrl` + `GatewayReauthRequiredError` (single-use
  OAuth ticket re-mint vs long-lived token fallback) into
  `@hermes/shared`; desktop now imports them directly.
- Add `buildHermesWebSocketUrl`, one base-path/scheme/auth-aware URL
  builder, and route every dashboard WS endpoint through it
  (`/api/ws`, `/api/events`, `/api/pty`, plugin WS URLs).
- Reduce the dashboard `GatewayClient` to a thin subclass of the shared
  `JsonRpcGatewayClient`, deleting ~210 lines of duplicated pending-call
  /event-dispatch/connect plumbing while keeping its dashboard-specific
  ticket-vs-token auth selection.
- Drop the stale "start it with --tui" chat banner, which implied the
  dashboard flag was required.

Behavior is preserved on both surfaces; the dashboard additionally
inherits the shared client's 15s connect timeout (previously
desktop-only), so a hung connect now fails fast instead of pinning the
composer in "connecting".

cae6b5486f feat(dashboard): always enable embedded chat; remove dashboard --tui flag 
The dashboard's embedded Chat surface (/chat, /api/ws, /api/pty) was gated
behind `hermes dashboard --tui` / HERMES_DASHBOARD_TUI=1. The desktop app and
the dashboard's own Chat tab both drive the agent over the /api/ws + /api/pty
WebSockets, so a dashboard started without the flag would pass the /api/status
health check but slam the chat WebSocket shut with WS code 4403 — the app
connects, reports "ready", and chat stays dead. This was the root cause behind
multiple user reports of the desktop app failing to connect to a self-hosted
gateway/dashboard, and it bit Docker and host installs alike.

Make the embedded chat unconditional:

- web_server.py: _DASHBOARD_EMBEDDED_CHAT_ENABLED defaults to True; drop the
  embedded_chat parameter and the runtime reassignment from start_server().
  The WS gates still read the constant (now always true) so the seam — and its
  "rejects when disabled" contract test — stays meaningful.
- main.py: remove the `--tui` argument from the dashboard subparser and the
  `embedded_chat = args.tui or HERMES_DASHBOARD_TUI==1` derivation.
- web/: isDashboardEmbeddedChatEnabled() returns true unconditionally; drop the
  deprecated __HERMES_DASHBOARD_TUI__ alias and the dead LEGACY_TUI_RE scrape in
  the vite dev-token plugin.
- apps/desktop/electron/main.cjs: drop `--tui` from the spawned dashboardArgs
  (it would now error with "unrecognized arguments: --tui") and the redundant
  HERMES_DASHBOARD_TUI env injection.
- Docker: no s6 run-script change needed — the script never passed --tui; the
  HERMES_DASHBOARD_TUI env var is now simply a no-op, so the image works out of
  the box with no extra var.
- Docs: remove every dashboard --tui / HERMES_DASHBOARD_TUI reference across the
  CLI reference, env-var reference, docker/desktop/web-dashboard guides, in-app
  tips, and the zh-Hans translations. The terminal `hermes --tui` / HERMES_TUI
  references are intentionally left untouched.

Tests: 270 passing across web_server, dashboard lifecycle, host-header,
auth-gate, and docker-override-scripts suites.

f49afd3122 feat(web): add /api/pty WebSocket bridge to embed TUI in dashboard 
Exposes hermes --tui over a PTY-backed WebSocket so the dashboard can
embed the real TUI rather than reimplement its surface. The browser
attaches xterm.js to the socket; keystrokes flow in, PTY output bytes
flow out.

Architecture:

    browser <Terminal> (xterm.js)
           │  onData ───► ws.send(keystrokes)
           │  onResize ► ws.send('\x1b[RESIZE:cols;rows]')
           │  write   ◄── ws.onmessage (PTY bytes)
           ▼
    FastAPI /api/pty (token-gated, loopback-only)
           ▼
    PtyBridge (ptyprocess) ── spawns node ui-tui/dist/entry.js ──► tui_gateway + AIAgent

Components
----------

hermes_cli/pty_bridge.py
  Thin wrapper around ptyprocess.PtyProcess: byte-safe read/write on the
  master fd via os.read/os.write (not PtyProcessUnicode — ANSI is
  inherently byte-oriented and UTF-8 boundaries may land mid-read),
  non-blocking select-based reads, TIOCSWINSZ resize, idempotent
  SIGHUP→SIGTERM→SIGKILL teardown, platform guard (POSIX-only; Windows
  is WSL-supported only).

hermes_cli/web_server.py
  @app.websocket("/api/pty") endpoint gated by the existing
  _SESSION_TOKEN (via ?token= query param since browsers can't set
  Authorization on WS upgrades). Loopback-only enforcement. Reader task
  uses run_in_executor to pump PTY bytes without blocking the event
  loop. Writer loop intercepts a custom \x1b[RESIZE:cols;rows] escape
  before forwarding to the PTY. The endpoint resolves the TUI argv
  through a _resolve_chat_argv hook so tests can inject fake commands
  without building the real TUI.

Tests
-----

tests/hermes_cli/test_pty_bridge.py — 12 unit tests: spawn, stdout,
stdin round-trip, EOF, resize (via TIOCSWINSZ + tput readback), close
idempotency, cwd, env forwarding, unavailable-platform error.

tests/hermes_cli/test_web_server.py — TestPtyWebSocket adds 7 tests:
missing/bad token rejection (close code 4401), stdout streaming,
stdin round-trip, resize escape forwarding, unavailable-platform ANSI
error frame + 1011 close, resume parameter forwarding to argv.

96 tests pass under scripts/run_tests.sh.

(cherry picked from commit 29b337bca7)

feat(web): add Chat tab with xterm.js terminal + Sessions resume button

(cherry picked from commit 3d21aee8 by emozilla, conflicts resolved
 against current main: BUILTIN_ROUTES table + plugin slot layout)

fix(tui): replace OSC 52 jargon in /copy confirmation

When the user ran /copy successfully, Ink confirmed with:

  sent OSC52 copy sequence (terminal support required)

That reads like a protocol spec to everyone who isn't a terminal
implementer. The caveat was a historical artifact — OSC 52 wasn't
universally supported when this message was written, so the TUI
honestly couldn't guarantee the copy had landed anywhere.

Today every modern terminal (including the dashboard's embedded
xterm.js) handles OSC 52 reliably. Say what the user actually wants
to know — that it copied, and how much — matching the message the
TUI already uses for selection copy:

  copied 1482 chars

(cherry picked from commit a0701b1d5a)

docs: document the dashboard Chat tab

AGENTS.md — new subsection under TUI Architecture explaining that the
dashboard embeds the real hermes --tui rather than rewriting it,
with pointers to the pty_bridge + WebSocket endpoint and the rule
'never add a parallel chat surface in React.'

website/docs/user-guide/features/web-dashboard.md — user-facing Chat
section inside the existing Web Dashboard page, covering how it works
(WebSocket + PTY + xterm.js), the Sessions-page resume flow, and
prerequisites (Node.js, ptyprocess, POSIX kernel / WSL on Windows).

(cherry picked from commit 2c2e32cc45)

feat(tui-gateway): transport-aware dispatch + WebSocket sidecar

Decouples the JSON-RPC dispatcher from its I/O sink so the same handler
surface can drive multiple transports concurrently. The PTY chat tab
already speaks to the TUI binary as bytes — this adds a structured
event channel alongside it for dashboard-side React widgets that need
typed events (tool.start/complete, model picker state, slash catalog)
that PTY can't surface.

- `tui_gateway/transport.py` — `Transport` protocol + `contextvars` binding
  + module-level `StdioTransport` fallback. The stdio stream resolves
  through a lambda so existing tests that monkey-patch `_real_stdout`
  keep passing without modification.
- `tui_gateway/ws.py` — WebSocket transport implementation; FastAPI
  endpoint mounting lives in hermes_cli/web_server.py.
- `tui_gateway/server.py`:
  - `write_json` routes via session transport (for async events) →
    contextvar transport (for in-request writes) → stdio fallback.
  - `dispatch(req, transport=None)` binds the transport for the request
    lifetime and propagates it to pool workers via `contextvars.copy_context`
    so async handlers don't lose their sink.
  - `_init_session` and the manual-session create path stash the
    request's transport so out-of-band events (subagent.complete, etc.)
    fan out to the right peer.

`tui_gateway.entry` (Ink's stdio handshake) is unchanged externally —
it falls through every precedence step into the stdio fallback, byte-
identical to the previous behaviour.

feat(web): ChatSidebar — JSON-RPC sidecar next to xterm.js terminal

Composes the two transports into a single Chat tab:

  ┌─────────────────────────────────────────┬──────────────┐
  │  xterm.js / PTY  (emozilla #13379)      │ ChatSidebar  │
  │  the literal hermes --tui process       │  /api/ws     │
  └─────────────────────────────────────────┴──────────────┘
        terminal bytes                          structured events

The terminal pane stays the canonical chat surface — full TUI fidelity,
slash commands, model picker, mouse, skin engine, wide chars all paint
inside the terminal. The sidebar opens a parallel JSON-RPC WebSocket
to the same gateway and renders metadata that PTY can't surface to
React chrome:

  • model + provider badge with connection state (click → switch)
  • running tool-call list (driven by tool.start / tool.progress /
    tool.complete events)
  • model picker dialog (gateway-driven, reuses ModelPickerDialog)

The sidecar is best-effort. If the WS can't connect (older gateway,
network hiccup, missing token) the terminal pane keeps working
unimpaired — sidebar just shows the connection-state badge in the
appropriate tone.

- `web/src/components/ChatSidebar.tsx` — new component (~270 lines).
  Owns its GatewayClient, drives the model picker through
  `slash.exec`, fans tool events into a capped tool list.
- `web/src/pages/ChatPage.tsx` — split layout: terminal pane
  (`flex-1`) + sidebar (`w-80`, `lg+` only).
- `hermes_cli/web_server.py` — mount `/api/ws` (token + loopback
  guards mirror /api/pty), delegate to `tui_gateway.ws.handle_ws`.

refactor(web): /clean pass on ChatSidebar + ChatPage lint debt

- ChatSidebar: lift gw out of useRef into a useMemo derived from a
  reconnect counter. React 19's react-hooks/refs and react-hooks/
  set-state-in-effect rules both fire when you touch a ref during
  render or call setState from inside a useEffect body. The
  counter-derived gw is the canonical pattern for "external resource
  that needs to be replaceable on user action" — re-creating the
  client comes from bumping `version`, the effect just wires + tears
  down. Drops the imperative `gwRef.current = …` reassign in
  reconnect, drops the truthy ref guard in JSX. modelLabel +
  banner inlined as derived locals (one-off useMemo was overkill).
- ChatPage: lazy-init the banner state from the missing-token check
  so the effect body doesn't have to setState on first run. Drops
  the unused react-hooks/exhaustive-deps eslint-disable. Adds a
  scoped no-control-regex disable on the SGR mouse parser regex
  (the \\x1b is intentional for xterm escape sequences).

All my-touched files now lint clean. Remaining warnings on web/
belong to pre-existing files this PR doesn't touch.

Verified: vitest 249/249, ui-tui eslint clean, web tsc clean,
python imports clean.

chore: uptick

fix(web): drop ChatSidebar tool list — events can't cross PTY/WS boundary

The /api/pty endpoint spawns `hermes --tui` as a child process with its
own tui_gateway and _sessions dict; /api/ws runs handle_ws in-process in
the dashboard server with a separate _sessions dict. Tool events fire on
the child's gateway and never reach the WS sidecar, so the sidebar's
tool.start/progress/complete listeners always observed an empty list.

Drop the misleading list (and the now-orphaned ToolCall primitive),
keep model badge + connection state + model picker + error banner —
those work because they're sidecar-local concerns. Surfacing tool calls
in the sidebar requires cross-process forwarding (PTY child opens a
back-WS to the dashboard, gateway tees emits onto stdio + sidecar
transport) — proper feature for a follow-up.

feat(web): wire ChatSidebar tool list to PTY child via /api/pub broadcast

The dashboard's /api/pty spawns hermes --tui as a child process; tool
events fire in the python tui_gateway grandchild and never crossed the
process boundary into the in-process WS sidecar — so the sidebar tool
list was always empty.

Cross-process forwarding:

- tui_gateway: TeeTransport (transport.py) + WsPublisherTransport
  (event_publisher.py, sync websockets client). entry.py installs the
  tee on _stdio_transport when HERMES_TUI_SIDECAR_URL is set, mirroring
  every dispatcher emit to a back-WS without disturbing Ink's stdio
  handshake.

- hermes_cli/web_server.py: new /api/pub (publisher) + /api/events
  (subscriber) endpoints with a per-channel registry. /api/pty now
  accepts ?channel= and propagates the sidecar URL via env. start_server
  also stashes app.state.bound_port so the URL is constructable.

- web/src/pages/ChatPage.tsx: generates a channel UUID per mount,
  passes it to /api/pty and as a prop to ChatSidebar.

- web/src/components/ChatSidebar.tsx: opens /api/events?channel=, fans
  tool.start/progress/complete back into the ToolCall list. Restores
  the ToolCall primitive.

Tests: 4 new TestPtyWebSocket cases cover channel propagation,
broadcast fan-out, and missing-channel rejection (10 PTY tests pass,
120 web_server tests overall).

fix(web): address Copilot review on #14890

Five threads, all real:

- gatewayClient.ts: register `message`/`close` listeners BEFORE awaiting
  the open handshake.  Server emits `gateway.ready` immediately after
  accept, so a listener attached after the open promise could race past
  the initial skin payload and lose it.

- ChatSidebar.tsx: wire `error`/`close` on the /api/events subscriber
  WS into the existing error banner.  4401/4403 (auth/loopback reject)
  surface as a "reload the page" message; mid-stream drops surface as
  "events feed disconnected" with the existing reconnect button.  Clean
  unmount closes (1000/1001) stay silent.

- web-dashboard.md: install hint was `pip install hermes-agent[web]` but
  ptyprocess lives in the `pty` extra, not `web`.  Switch to
  `hermes-agent[web,pty]` in both prerequisite blocks.

- AGENTS.md: previous "never add a parallel React chat surface" guidance
  was overbroad and contradicted this PR's sidebar.  Tightened to forbid
  re-implementing the transcript/composer/PTY terminal while explicitly
  allowing structured supporting widgets (sidebar / model picker /
  inspectors), matching the actual architecture.

- web/package-lock.json: regenerated cleanly so the wterm sibling
  workspace paths (extraneous machine-local entries) stop polluting CI.

Tests: 249/249 vitest, 10/10 PTY/events, web tsc clean.

refactor(web): /clean pass on ChatSidebar events handler

Spotted in the round-2 review:

- Banner flashed on clean unmount: `ws.close()` from the effect cleanup
  fires `close` with code 1005, opened=true, neither 1000 nor 1001 —
  hit the "unexpected drop" branch.  Track `unmounting` in the effect
  scope and gate the banner through a `surface()` helper so cleanup
  closes stay silent.

- DRY the duplicated "events feed disconnected" string into a local
  const used by both the error and close handlers.

- Drop the `opened` flag (no longer needed once the unmount guard is
  the source of truth for "is this an expected close?").

feat: web UI dashboard for managing Hermes Agent (#8756) 
* feat: web UI dashboard for managing Hermes Agent (salvage of #8204/#7621)

Adds an embedded web UI dashboard accessible via `hermes web`:
- Status page: agent version, active sessions, gateway status, connected platforms
- Config editor: schema-driven form with tabbed categories, import/export, reset
- API Keys page: set, clear, and view redacted values with category grouping
- Sessions, Skills, Cron, Logs, and Analytics pages

Backend:
- hermes_cli/web_server.py: FastAPI server with REST endpoints
- hermes_cli/config.py: reload_env() utility for hot-reloading .env
- hermes_cli/main.py: `hermes web` subcommand (--port, --host, --no-open)
- cli.py / commands.py: /reload slash command for .env hot-reload
- pyproject.toml: [web] optional dependency extra (fastapi + uvicorn)
- Both update paths (git + zip) auto-build web frontend when npm available

Frontend:
- Vite + React + TypeScript + Tailwind v4 SPA in web/
- shadcn/ui-style components, Nous design language
- Auto-refresh status page, toast notifications, masked password inputs

Security:
- Path traversal guard (resolve().is_relative_to()) on SPA file serving
- CORS localhost-only via allow_origin_regex
- Generic error messages (no internal leak), SessionDB handles closed properly

Tests: 47 tests covering reload_env, redact_key, API endpoints, schema
generation, path traversal, category merging, internal key stripping,
and full config round-trip.

Original work by @austinpickett (PR #1813), salvaged by @kshitijk4poor
(PR #7621 → #8204), re-salvaged onto current main with stale-branch
regressions removed.

* fix(web): clean up status page cards, always rebuild on `hermes web`

- Remove config version migration alert banner from status page
- Remove config version card (internal noise, not surfaced in TUI)
- Reorder status cards: Agent → Gateway → Active Sessions (3-col grid)
- `hermes web` now always rebuilds from source before serving,
  preventing stale web_dist when editing frontend files

* feat(web): full-text search across session messages

- Add GET /api/sessions/search endpoint backed by FTS5
- Auto-append prefix wildcards so partial words match (e.g. 'nimb' → 'nimby')
- Debounced search (300ms) with spinner in the search icon slot
- Search results show FTS5 snippets with highlighted match delimiters
- Expanding a search hit auto-scrolls to the first matching message
- Matching messages get a warning ring + 'match' badge
- Inline term highlighting within Markdown (text, bold, italic, headings, lists)
- Clear button (x) on search input for quick reset
