CI: create the WOW64 junctions in the workflow instead of by hand

The Windows fix was the only part of it living outside git — two
junctions created by hand on the build VM. Rebuild that VM, add a second
Windows runner, or reset the SYSTEM profile and Windows builds break
again with an error that points nowhere near the cause.

Tauri downloads candle.exe, light.exe and makensis.exe, and all three
are 32-bit. A runner running as SYSTEM has %LOCALAPPDATA% under
C:\Windows\System32\config\systemprofile, and WOW64 redirection serves
32-bit processes reading System32 from SysWOW64, where those directories
do not exist. The bundlers cannot see their own folder: candle exits
0x80131700, makensis reports "Unable to start child process, error 0x2",
and Tauri surfaces neither — only "failed to run candle.exe".

The job now junctions the SysWOW64 view onto the System32 originals when
it detects a profile inside System32, and skips entirely otherwise, so a
runner running as a normal user is unaffected. Idempotent, and written
with goto rather than nested blocks to avoid the delayed-expansion trap
that already bit the MSVC step.

Verified rather than assumed: the hand-made junctions were deleted from
the build VM before this was pushed, so this run has to recreate them.

 ### Frontend Structure (`app/src/`)
 
-- **`store/appState.ts`** — Single Zustand store for all app state (projects, sessions, UI)
+- **`store/appState.ts`** — Single Zustand store for all app state (projects, sessions, UI). The
+  main area is a single ordered tab strip holding two tab kinds, keyed `term:<id>` and
+  `home:<id>`; `activeSessionId` is *derived* from `activeTabKey` so exactly one thing is current.
 - **`hooks/`** — All Tauri IPC calls are encapsulated in hooks (`useTerminal`, `useProjects`, `useDocker`, `useSettings`)
 - **`lib/tauri-commands.ts`** — Typed `invoke()` wrappers; TypeScript types in `lib/types.ts` must match Rust models
 - **`components/terminal/TerminalView.tsx`** — xterm.js integration with WebGL rendering, URL detection for OAuth flow
-- **`components/layout/`** — TopBar (tabs + status), Sidebar (project list), StatusBar
-- **`components/projects/`** — ProjectCard, ProjectList, AddProjectDialog
-- **`components/settings/`** — Settings panels for API keys, Docker, AWS
+- **`components/layout/`** — TopBar, MainTabs (the unified tab strip), Sidebar, StatusBar
+- **`components/projects/`** — `ProjectRow` (select-only list row), `ProjectList`, `AddProjectDialog`,
+  and the editors reused by Project Home
+- **`components/projects/home/`** — **Project Home**, the main-area view for a project:
+  Overview / Sessions / Automation / Config / Files. Per-project configuration lives here, not in
+  modals — see "UI conventions" below.
+- **`components/settings/`** — Host-level settings: Docker, AWS, Web Terminal, STT, shared auth
+- **`components/ui/`** — Shared primitives. **Use these; do not hand-roll replacements.**
+  `Modal` (the only correct way to build a dialog — it supplies `role="dialog"`, `aria-modal`,
+  focus trap and restore), `Button`, `Toggle`, `Field`, `SegmentedControl`, `StatusIndicator`,
+  `SaveIndicator`, `OverflowMenu`, `ToastHost`, `Tooltip`
+
+### UI conventions
+
+- **Project config belongs in Project Home's Config tab, not a modal.** Modals are reserved for
+  short, genuinely modal tasks (add project, confirm removal, token acquisition). The app
+  previously had ~12 hand-rolled modals; they were consolidated deliberately.
+- **Never bypass the design tokens.** All colour comes from CSS custom properties in `index.css`.
+  Filled buttons use `--accent-emphasis` (not `--accent`, which fails WCAG AA against white).
+  Use `--text-disabled` rather than `disabled:opacity-50`.
+- **Never write `focus:outline-none`.** A global `:focus-visible` ring is defined in `index.css`.
+- **Status must not be encoded in colour alone** — `StatusIndicator` pairs a glyph with a word.
+- Keyboard: `Ctrl+T` new terminal, `Ctrl+Shift+W` close tab, `Ctrl+Tab` cycle, `Ctrl+1..9` jump.
+  `Ctrl+W` is intentionally left alone — it is readline's `kill-word` inside the terminal.
 
 ### Backend Structure (`app/src-tauri/src/`)
 
-- **`commands/`** — Tauri command handlers (docker, project, settings, terminal). These are the IPC entry points called by `invoke()`.
+- **`commands/`** — Tauri command handlers. These are the IPC entry points called by `invoke()`.
+  Beyond docker/project/settings/terminal: `inspect_commands.rs` (read-only views into a
+  container — Claude sessions, installed capabilities, scheduler tasks), `auth_bridge_commands.rs`,
+  `auth_token_commands.rs`.
+- **`auth_bridge/`** — Host-side loopback bridge so browser logins run *inside* a container can
+  complete against the host browser. Discovers listeners by parsing `/proc/net/tcp{,6}` (the image
+  has no `ss`/`netstat`/`lsof`), binds host `127.0.0.1` **only**, and tunnels in over the Docker
+  API via `socat`. Opt-in per project.
+- **`browser_view/`** — Watch and take over the browser Claude drives with Playwright inside the
+  container. Runs Playwright's own dashboard (`browser.bind()` + `playwright-cli show`) in the
+  container and fronts it with a **token-gated** loopback proxy. Deliberately does **not** reuse
+  the auth bridge's `PortForward`, which binds an unauthenticated port — fine for a throwaway
+  OAuth listener, wrong for remote control of a browser. Host ports are confined to
+  `47820..=47827` because CSP `frame-src` cannot express a port range and must enumerate them;
+  a unit test asserts the Rust range matches `tauri.conf.json`. Opt-in per project.
 - **`docker/`** — Docker API layer using bollard:
   - `client.rs` — Singleton Docker connection via `OnceLock`
   - `container.rs` — Container lifecycle (create, start, stop, remove, inspect)
-  - `exec.rs` — PTY exec sessions with bidirectional stdin/stdout streaming
+  - `exec.rs` — Attached exec streaming. `create_attached_exec()` is the **single** place an
+    attached exec is opened; terminal sessions and the auth bridge both go through it.
   - `image.rs` — Image build/pull with progress streaming
-- **`models/`** — Serde structs (`Project`, `AuthMode`, `BedrockConfig`, `OllamaConfig`, `LiteLlmConfig`, `ContainerInfo`, `AppSettings`). These define the IPC contract with the frontend.
+  - `gateway.rs` — Optional LiteLLM sibling container giving Claude Code an Anthropic-format
+    front end for providers that only speak OpenAI (see `gateway-container/`). Mirrors `stt.rs`.
+    Its bind address is **detected, never `0.0.0.0`** — unlike STT, *project containers* consume
+    it, so loopback alone is not always enough: Docker Desktop gets `127.0.0.1` (containers reach
+    it via `host.docker.internal`), native Linux gets the default bridge gateway (`172.17.0.1`).
+    `GatewayBinding` derives the bind address and the advertised `base_url` together so they
+    cannot drift. A wildcard bind would be LAN-reachable — Docker's rules precede host firewalls —
+    in front of a container config holding a billed provider key. It also **always** sets a
+    LiteLLM `master_key`, since LiteLLM without one accepts any key.
+  - `migration.rs` — Base-image migration: manifest capture via throwaway containers, the pure
+    delta computation (dpkg-ownership filter, bind-mount exclusion, verbatim-copy set), and the
+    crash-recovery state machine. See "Base-image migration" below.
+  - `legacy_cleanup.rs` — One-release migration shim removing leftovers from the deleted MCP
+    feature (containers labelled `triple-c.mcp-server`, `triple-c-net-*` networks). Deletable once
+    users have migrated.
+- **`web_terminal/`** — Remote terminal access via axum HTTP+WebSocket server:
+  - `server.rs` — Axum server lifecycle (start/stop), serves embedded HTML and handles WS upgrades
+  - `ws_handler.rs` — Per-connection WebSocket handler with JSON protocol, session management, cleanup on disconnect
+  - `terminal.html` — Self-contained xterm.js web UI embedded via `include_str!()`
+- **`models/`** — Serde structs (`Project`, `Backend`, `BedrockConfig`, `OllamaConfig`, `LlamaCppConfig`, `OpenAiCompatibleConfig`, `ClaudeCodeSettings`, `ContainerInfo`, `AppSettings`, `WebTerminalSettings`). These define the IPC contract with the frontend.
 - **`storage/`** — Persistence: `projects_store.rs` (JSON file with atomic writes), `secure.rs` (OS keychain via `keyring` crate), `settings_store.rs`
 
 ### Container (`container/`)
 
 - **`Dockerfile`** — Ubuntu 24.04 base with Claude Code, Node.js 22, Python 3.12, Rust, Docker CLI, git, gh, AWS CLI v2, ripgrep, pnpm, uv, ruff pre-installed
-- **`entrypoint.sh`** — UID/GID remapping to match host user, SSH key setup, git config, docker socket permissions, then `sleep infinity`
+- **`entrypoint.sh`** — UID/GID remapping to match host user, SSH key setup, git config, docker socket permissions, Claude Code settings.json injection, then `sleep infinity`
 - **`triple-c-scheduler`** — Bash-based scheduled task system for recurring Claude Code invocations
 
+**`/home/claude` in the image is seed-only.** It is the mount point of the named volume
+`triple-c-home-{projectId}`, so after a project's *first* start the image's copy of that directory
+is masked permanently and can never be updated again. A change you make under `/home/claude` in
+the `Dockerfile` or in `entrypoint.sh`'s "copy this into the home dir" style reaches **new
+projects only** — existing ones will never see it, with or without a base-image migration.
+
+So: **anything that must stay upgradable belongs in `/usr/local/bin` or `/opt`, or must be seeded
+by `entrypoint.sh` at runtime** (i.e. written on every start, from a source outside the home
+volume, the way `CLAUDE_INSTRUCTIONS` → `~/.claude/CLAUDE.md` and the Mission Control skill copy
+already are). Putting it in the image's `/home/claude` and expecting an image update to deliver it
+is the mistake.
+
+The flip side is the useful half of the same fact: Claude Code itself (`~/.local/bin`), cargo, uv,
+ruff, the OAuth login, `~/.claude.json`, skills, transcripts, scheduler tasks and SSH keys all
+re-attach for free when a container is recreated from a *different* image — which is what makes
+base-image migration cheap.
+
 ### Container Lifecycle
 
-Containers use a **stop/start** model (not create/destroy). Installed packages persist across stops. The `.claude` config dir uses a named Docker volume (`triple-c-claude-config-{projectId}`) so OAuth tokens survive even container resets.
+Containers use a **stop/start** model (not create/destroy). Installed packages persist across stops. The `.claude` config dir uses a named Docker volume (`triple-c-claude-config-{projectId}`), nested inside the home volume (`triple-c-home-{projectId}`), so OAuth tokens and Claude Code config survive container stop/start *and* container recreation.
+
+**Reset is the exception and it is destructive.** `rebuild_project_container` calls
+`remove_project_volumes`, which deletes *both* volumes — so a Reset wipes `~/.claude`,
+`~/.claude.json`, the OAuth credential, installed skills, and session transcripts. That is
+intentional (Reset exists to get back to a clean base image), but do not describe Reset as
+preserving credentials.
+
+### Base-image migration (`docker/migration.rs`, `commands/migration_commands.rs`)
+
+A container is created from `triple-c-snapshot-{projectId}:latest` whenever that image exists, and
+every recreation re-commits it — so without an explicit act, a project stays on the base image it
+was first built from **forever** and never picks up a new `socat`, a new `/usr/local/bin` shim or a
+security update. Migration is the non-destructive way out; Reset is the destructive one.
+
+- **Staleness is a surfaced signal, not an automatic trigger.** `triple-c.base-image-id` records
+  the lineage but is deliberately **not** compared in `container_needs_recreation` — see the long
+  comment there. Comparing it would recreate every project *from its own snapshot* on the next base
+  bump: churn on the old base, and it would consume the "you should migrate" signal without
+  migrating. `get_container_staleness` surfaces it; `migrate_project_to_base` acts on it.
+- **A missing lineage label means "unknown, probe instead", never "stale".**
+- **`:latest` keeps pointing at the old lineage until the final commit.** That is what makes every
+  crash before that point self-heal — `start_project_container` just recreates from the old
+  snapshot. After the container swap, the new container's `triple-c.migration-state=in-progress`
+  label plus the persisted state file let `reconcile_project_statuses` offer resume or rollback.
+- **Rollback restores the system layer only.** The volumes are never touched at any point, so work
+  done in `$HOME` during a migrated session survives a rollback. Say so in any UI copy.
+- **`/var` is never copied either, and that is the one way migration is *more* destructive than
+  the ordinary recreate.** A recreate builds from the project's snapshot, so `/var/lib/postgresql`
+  rides along; a migration builds from the base and the apt replay hands back an empty cluster.
+  Copying a live database's files onto a different base's version of the same package is a
+  corruption risk, not a fix — so the answer is disclosure. `unpreserved_data()` reports
+  first-level directories under `/var/lib` and `/var/www` that the base does not ship *and* that
+  hold non-dpkg-owned files (which is what keeps `/var/lib/apt` and `/var/lib/dpkg` out of it),
+  and the pre-flight, the banner and the finished report all name them. Do not make this silent.
+- **The rollback pin is not best-effort.** After `commit_container_snapshot` the commit is the only
+  copy of the old system layer, so a `docker tag` that fails — or succeeds without the reference
+  resolving — aborts the migration before `remove_container`. Same rule in reverse for
+  `rollback_migration`: the image is confirmed to exist before the container is destroyed.
+- **`resume` must check the container's `triple-c.migration-state` label**, exactly as
+  `reconcile_migration` does. Without it a record left behind by a failed commit "resumes" into
+  the *old, unmigrated* container and commits it as migrated.
+- **Anything that stops, removes or recreates a project's container consults
+  `migration_commands::is_migrating`.** The window between `remove_container` and the create that
+  follows looks exactly like "no container" to Start, and Reset would delete the volumes out from
+  under a live run.
+- **`/etc` is never copied**, only reported: the snapshot lineage has
+  `/etc/apt/sources.list.d/nodesource.sources` where the current base has `nodesource.list`, and
+  having both breaks every `apt-get update` on a duplicate source. Verified, not theoretical.
+- **`docker diff` is useless here** — on a snapshot-derived container it reports only changes since
+  the last commit. Migration diffs two filesystem manifests instead, filtered through dpkg
+  ownership and presence-in-the-new-base. Measured on a real project, that turns 8,677 raw path
+  differences into 2 genuinely user-authored ones.

+# Triple-C Design & Product Review
+
+**Date:** 2026-08-09 · **Version reviewed:** 0.3.0 · **Reviewer:** Fable 5
+
+Scope: `app/src/` (App, layout, projects, settings, terminal, ui, store, index.css),
+README/CLAUDE.md/TODO.md, the four repo screenshots, and `triple-c-app-logov2.png`.
+
+---
+
+## Summary verdict
+
+The bones are good. The floating-panel layout reads clean, the GitHub-dark palette is
+inoffensive, and terminal-as-centerpiece is correct for this product.
+
+The two real problems are structural, and they are the same problem seen from two sides:
+**the project — the app's actual unit of work — has no room to live.** Everything about a
+project (backend auth, mounts, git identity, env vars, ports, Claude settings, file
+manager) is stuffed into a ~280px sidebar card (`ProjectCard.tsx`, 1,257 lines) that
+sprays out seven modals to compensate.
+
+`screenshot_for_fix/project_config_run_off.png` is not a bug to patch. It is the
+architecture reporting that the config does not fit where it lives. Fixing that one thing
+also solves the modal pile, the density problems, *and* creates the surface where newer
+Claude Code concepts belong.
+
+---
+
+## Part A — Visual & interaction design
+
+### A1. Tokens: coherent but thin, with one real contrast failure
+
+`index.css` is GitHub Primer dark, verbatim (`#0d1117 / #161b22 / #21262d / #30363d /
+#8b949e / #58a6ff`). Defensible — familiar, calm, terminal-adjacent — but the token layer
+stops at 11 variables. Roles the code is already faking ad hoc:
+
+- **No elevation/overlay token.** Modals reuse `--bg-secondary`, so a modal over the
+  sidebar is the same color as the sidebar. Add `--bg-overlay: #1c2128` and
+  `--shadow-overlay`.
+- **No muted-accent tokens.** The code hand-rolls `bg-yellow-500/20 text-yellow-400`,
+  `bg-blue-500/20 text-blue-400`, `--warning/15`, `--error/10`. Add `--accent-muted`,
+  `--warning-muted`, `--error-muted`, `--success-muted`. Those raw Tailwind palette colors
+  are the only two places the token system leaks.
+- **Radius drift:** `rounded` (4px), `rounded-lg` (8px), plus hardcoded 3px/6px in help
+  styles. Pick two: 6px controls, 8px panels.
+
+**Contrast bug (concrete):** white text on `--accent #58a6ff` is ~**2.5:1** — fails WCAG
+AA. That is the primary button ("Add Project"), the "Update" pill, and more. Primer solves
+this with two accents: keep `#58a6ff` as the *foreground/link* accent and add
+`--accent-emphasis: #1f6feb` for filled buttons (white on `#1f6feb` ≈ 4.7:1).
+
+Same story for `bg-[var(--success)] text-white` ON toggles — `#3fb950` + white ≈ **2.1:1**,
+the worst offender in the app.
+
+What passes: `--text-secondary #8b949e` on `#161b22` ≈ 5.8:1, fine even at 12px.
+`--warning #d29922` ≈ 7:1. But `disabled:opacity-50` on secondary text drops to ~2.4:1 —
+and since the entire config form is disabled while the container runs, **the most common
+state of the form is illegible.** Use a dedicated `--text-disabled: #6e7681` instead of
+opacity.
+
+### A2. Type and density: everything is 12px
+
+Roughly 90% of the UI is `text-xs`. Hierarchy is carried almost entirely by weight plus a
+single `text-lg` modal title. Forms feel cramped rather than dense — density is
+information per pixel, not small type.
+
+Proposed scale with roles: **11px** uppercase section labels (already used, keep) ·
+**12px** secondary/meta · **13px** default UI/body/form values · **14px** panel headers ·
+**16px** view titles.
+
+Path strings in mono are a nice identity touch — extend mono to all machine values (model
+IDs, ports, digests), which the Bedrock/Ollama forms currently render in the UI face.
+
+The outer chrome spends generously while content starves: `App.tsx` wraps everything in
+`p-6 gap-4`, then the config form gets ~180px-wide inputs for AWS secret keys. Keep the
+floating-island look; `p-3 gap-3` buys content ~24px horizontally and the terminal two
+more rows.
+
+### A3. The project card is three components wearing one div
+
+`ProjectCard` is simultaneously a list row, a command strip, and the entire settings form.
+
+- **Selection and disclosure are conflated.** Clicking a row both selects it and expands an
+  accordion in place, shoving the other projects down. The 06-28 screenshot shows 18
+  projects — this jank is daily.
+- **Actions are unstyled text links.** `ActionButton` renders `text-xs px-2 py-0.5` colored
+  text with no border or background, so Start/Stop/Terminal/Shell/Files/Backup/Config/Remove
+  read as a wrapping line of links. Worse, **Remove (destructive, red) wraps directly next
+  to Config** with a ~20px hit target.
+- **Double-click-to-rename** is undiscoverable and keyboard/touch-inaccessible.
+- **27 hover-only `<Tooltip>` markers in ProjectCard alone.** When a form needs 27 tooltips,
+  the form is the problem.
+
+### A4. Modals: eight is a pattern smell, and none are real dialogs
+
+Hanging off ProjectCard: EnvVars, PortMappings, ClaudeInstructions, ClaudeCodeSettings,
+ContainerProgress, FileManager, ConfirmRemove — plus AddProject, three reused from
+SettingsPanel, and Update/ImageUpdate/Help from TopBar.
+
+Each reimplements the overlay div, Escape handler, and click-outside logic by hand. **None
+has `role="dialog"`, `aria-modal`, a focus trap, or focus restore** — zero hits for
+`role=`, `aria-modal`, or `tabIndex` across `components/`.
+
+The pattern is wrong not because modals are bad, but because these are not modal *tasks*.
+Env vars, ports, instructions, and Claude settings are all "edit part of the project
+config" — a detail view's job.
+
+- Legitimately modal: **ConfirmRemove**, **AddProject**.
+- **FileManager** wants to be a main-area tab, not a 42rem popup.
+- **ContainerProgressModal actively hurts:** starting a container blocks the entire app
+  behind an overlay for an operation designed to be routine. Replace with inline row state
+  plus an error toast.
+- Whatever survives should be one shared `<Modal>` primitive with focus trap + ARIA.
+
+### A5. Keyboard and focus: currently unsupported
+
+For a tool whose centerpiece is a keyboard-driven terminal, the chrome is mouse-only.
+
+- Inputs use `focus:outline-none` with only a low-contrast border swap; **buttons have no
+  focus style at all** — tabbing through the sidebar is invisible.
+- One-line fix: add `--focus-ring: #58a6ff` and
+  `:focus-visible { outline: 2px solid var(--focus-ring); outline-offset: 1px; }`
+- No shortcuts for constant actions: `Ctrl+T` new terminal, `Ctrl+Tab`/`Ctrl+1..9` switch,
+  `Ctrl+W` close, `Ctrl+P` project switcher. The only shortcut in the app is the STT mic.
+- Hit targets below 24px: tab close "×" (~14px), Tooltip "?" (14px), Browse "...". The
+  status bar is `h-6` yet hosts two interactive controls.
+
+### A6. Status communication
+
+Three disconnected dot systems (TopBar Docker/Image, per-project status, StatusBar counts),
+all 8px and color-only.
+
+- **Stopped (gray) and error (red) differ only by hue**, and Docker-unavailable renders the
+  same gray as Docker-still-being-checked (`dockerAvailable === null` and `false` both fall
+  through). An outage should be loud; unknown should pulse.
+- Color-only encoding fails colorblind users. Add shape or text — `● Running`, `○ Stopped`,
+  `⚠ Error`. The words are already in the model.
+- Raw `String(e)` errors dumped into a 12px card line; bollard errors are long. Errors need
+  a home: toast plus expandable detail.
+- The TopBar tab strip is visually disconnected from the terminal it controls. Move tabs
+  onto the terminal panel's top edge so the active tab connects to its content.
+
+### A7. Empty and first-run states
+
+`WelcomeScreen` is three lines of gray text with no affordance — "Add a project from the
+sidebar" *describes* a button instead of *being* one. This is also where brand could exist:
+the orange sun-gear logo appears nowhere in the UI and shares no DNA with the blue-on-
+graphite chrome.
+
+Make it an onboarding checklist reusing state already tracked:
+✓ Docker detected → ✓ Image pulled → **[ Add your first project ]** → open terminal.
+The same pattern fixes the "image missing" case, today just a gray dot in the corner.
+
+### A8. Dark-only: keep it
+
+Right call. Terminal-first developer tool, xterm content is dark, audience expects it. The
+tokens make a light theme cheap later. Don't spend on it now — but keep discipline that no
+color bypasses the token layer.
+
+### A9. Iconography
+
+Mixed: hand-inlined Feather-style SVGs in the sidebar rail, text glyphs elsewhere ("×",
+"?", "...", "+", "✓", "✕"). Adopt `lucide-react` — same stroke style already being
+imitated, tree-shakeable — and replace the text glyphs. It also supplies the per-concept
+icons Part B needs.
+
+---
+
+## Part B — Information architecture & product concepts
+
+### B1. The diagnosis
+
+Current IA: `Projects | MCP | Settings` in a sidebar, terminal in main, project detail
+crammed into the list.
+
+Deleting the MCP tab was correct — but **the lesson matters more than the freed slot.
+MCP died as a Triple-C feature because Claude Code absorbed it.** Hooks, skills, agents,
+plugins, output styles, and statusline are all the same species: files under `.claude/`
+that Claude Code manages natively with its own TUIs (`/agents`, `/hooks`, `/plugins`). If
+Triple-C builds form editors for them, it loses the same race again and becomes exactly
+what it should fear — a settings-file editor with a GUI skin.
+
+What Claude Code *cannot* do is what Triple-C uniquely owns: **the container boundary and
+what persists behind it.** The config volume, the workspace mounts, the lifecycle, the
+scheduler already shipping in every image, and the fleet view across many projects.
+
+> **Principle: Triple-C shows state and launches things. Claude Code edits its own config.**
+
+Sessions, checkpoints, background tasks, scheduled tasks, capability inventory → surface
+them, read from the volume, launch into the terminal. Hook/skill/agent *editing* →
+deep-link into the terminal, don't rebuild.
+
+### B2. Proposed IA: three nouns
+
+**Project** (a sandboxed workspace) · **Session** (a resumable conversation) ·
+**Library** (reusable capabilities pushed into projects). Everything is one of these, or
+Settings.

+- **Main area** hosts two tab kinds: terminals (as today) and project-home tabs, like VS

+
+### B3. The four concepts worth building
+
+**1. Sessions & Resume — the flagship.** The stop/start container model creates a problem
+plain Claude Code doesn't have: stop a container, come back Tuesday, and "which
+conversation was I in?" is buried in the volume. Read session metadata via `docker exec`
+(the exec and tar plumbing already exists), list sessions with summary and age, and make
+**[Resume]** open a terminal running `claude --resume <id>`. Closing a terminal tab today
+silently abandons a session; it should say "Session saved — resume from Project Home."
+This turns the biggest architectural quirk into the best feature.
+
+Do **not** build a checkpoint browser. Mention rewind (`Esc Esc`) in Help and stop there.
+
+**2. Library — the MCP tab's successor.** The pattern was already invented three times:
+global MCP servers with per-project checkboxes, global Claude instructions, and Mission
+Control's bundled skill install. Generalize it once: a Library of **skills, agents, and
+slash commands** defined globally with per-project enable, synced into the container's
+`.claude` volume by the entrypoint. Across many projects, "write a skill once, enable it in
+twelve sandboxes" is genuinely differentiated. Keep the editor minimal — name plus markdown
+textarea, or "import from folder." Not a structured form per frontmatter field.
+
+**3. Permission mode as the hero control.** The whole pitch is "sandbox so you can safely
+go fast," yet that pitch is expressed as a scary boolean buried in a config accordion.
+Replace it with Claude Code's real vocabulary — a segmented control (**Plan / Default /
+Accept Edits / Bypass**) on Overview, echoed as a badge on terminal tabs, with sandbox
+state beside it. When sandbox is ON, Bypass loses its red paint ("contained by sandbox");
+when sandbox is OFF *and* Bypass is on, that is when caution color earns its place. This
+reframes the product's core value in the product's own UI.
+
+**4. Automation tab.** `triple-c-scheduler` ships in every container with
+add/list/logs/notifications — and its only UI is a CLAUDE.md paragraph telling Claude to
+run it. Wrap it: task list (name, cron, last run, enabled), toggle/run-now/view-log, and a
+notification badge on the project row. "Your nightly agent left you a note" is a reason to
+open the app in the morning. Fleet-of-scheduled-agents management across projects is
+something the Claude Code TUI does not offer.
+
+**Explicitly skip:** status line builder, output-styles editor, hook *editors* (surface the
+count, deep-link to the terminal), checkpoint browser, marketplace browser. Each is niche,
+natively handled, or a settings-editor trap.
+
+### B4. Coherence test
+
+Every screen answers exactly one question:
+
+| Screen | Question |
+|---|---|
+| Sidebar | What projects exist and are they up? |
+| Project Home | What can this sandbox do, and where did I leave off? |
+| Terminal | Do the work. |
+| Library | What capabilities do I reuse? |
+| Settings | How does the host behave? |
+
+Anything that doesn't answer one of those doesn't get a nav slot.
+
+---
+
+## Priorities
+
+### Tier 1 — high impact, cheap
+
+1. `:focus-visible` ring and stop stripping outlines (one CSS rule + token). Add
+   `Ctrl+T` / `Ctrl+W` / `Ctrl+1..9` / `Ctrl+Tab`.
+2. Contrast: `--accent-emphasis: #1f6feb` for filled buttons; kill white-on-`#3fb950`;
+   `--text-disabled` instead of `opacity-50`.
+3. Real buttons for project actions; Remove into an overflow menu; primary action filled.
+4. Inline start/stop progress and an error toast; delete `ContainerProgressModal`.
+5. Status dots get labels or shapes; Docker-down turns red; null state pulses.
+6. Welcome screen becomes an onboarding checklist with a real button, plus the logo.
+7. One shared `<Modal>` with focus trap and ARIA for the modals that remain.
+8. Permission-mode segmented control replacing the boolean.
+9. `lucide-react` icons; move the tab strip onto the terminal panel.
+
+### Tier 2 — high impact, expensive
+
+1. **Project Home tabbed view** — the structural fix that dissolves the modal pile and the
+   1,257-line ProjectCard. The forms already exist; this is mostly moving and splitting.
+2. **Sessions tab** with `claude --resume`.
+3. **Library** — generalize global→per-project sync to skills/agents/commands.
+4. **Automation tab** wrapping `triple-c-scheduler`, with notification badges.
+
+### Tier 3 — skip
+

+# Mission Control Setup Instructions
+
+Reference document for adding Flight Control methodology to any project.
+
+## How Triple-C Installs Mission Control
+
+When Mission Control is enabled for a project in Triple-C:
+
+1. **Bundled files install**: The Mission Control files bundled with Triple-C are copied to `/home/claude/mission-control/` (persisted in the config volume)
+2. **Skills install**: All skills from the bundled `.claude/skills/` are copied to `~/.claude/skills/` so Claude Code discovers them automatically as `/slash-commands`
+3. **Workspace symlink**: `/workspace/mission-control/` symlinks to the installed copy for methodology doc access
+4. **Global instructions**: Mission Control usage instructions are injected into `~/.claude/CLAUDE.md`
+
+This happens automatically on every container start, so skill updates from new Triple-C releases are picked up on restart.
+
+## Two pieces are needed per project:
+
+1. **Global CLAUDE.md** — Handled automatically by Triple-C when Mission Control is enabled
+2. **Project CLAUDE.md** — Add the Flight Operations section to each project's `CLAUDE.md`
+
+Then run `/init-project` to create the `.flightops/` directory.
+
+---
+
+## 1. Global CLAUDE.md Instructions
+
+These are **automatically injected by Triple-C** when Mission Control is enabled. For reference, the injected content is:
+
+```markdown
+## Mission Control
+
+The `/workspace/mission-control/` directory contains **Flight Control** — an AI-first development methodology for structured project management. Use it for all project work.
+
+### How It Works
+
+- **Mission Control is a tool, not a project.** It provides skills and methodology for managing other projects.
+- All Flight Control skills are installed as personal skills in `~/.claude/skills/` and are automatically available as `/slash-commands`
+- The methodology docs and project registry live in `/workspace/mission-control/`
+
+### When to Use
+
+When working on any project that has a `.flightops/` directory, follow the Flight Control methodology:
+1. Read the project's `.flightops/ARTIFACTS.md` to understand artifact storage
+2. Read `.flightops/FLIGHT_OPERATIONS.md` for the implementation workflow
+3. Use Mission Control skills for planning and execution
+
+### Available Skills
+
+| Skill | When to Use |
+|-------|-------------|
+| `/init-project` | Setting up a new project for Flight Control |
+| `/mission` | Defining new work outcomes (days-to-weeks scope) |
+| `/flight` | Creating technical specs from missions (hours-to-days scope) |
+| `/leg` | Generating implementation steps from flights (minutes-to-hours scope) |
+| `/agentic-workflow` | Executing legs with multi-agent workflow (implement, review, commit) |
+| `/flight-debrief` | Post-flight analysis after a flight lands |
+| `/mission-debrief` | Post-mission retrospective after completion |
+| `/daily-briefing` | Cross-project status report |
+
+### Key Rules
+
+- **Planning skills produce artifacts only** — never modify source code directly
+- **Phase gates require human confirmation** — missions before flights, flights before legs
+- **Legs are immutable once in-flight** — create new ones instead of modifying
+- **`/agentic-workflow` orchestrates implementation** — it spawns separate Developer and Reviewer agents
+- **Artifacts live in the target project** — not in mission-control
+```
+
+---
+
+## 2. Project CLAUDE.md Instructions
+
+Add this section to each project's `CLAUDE.md`:
+
+```markdown
+## Flight Operations
+
+This project uses Flight Control (bundled with Triple-C) for structured development.
+
+**Before any mission/flight/leg work, read these files in order:**
+1. `.flightops/README.md` — What the flightops directory contains
+2. `.flightops/FLIGHT_OPERATIONS.md` — **The workflow you MUST follow**
+3. `.flightops/ARTIFACTS.md` — Where all artifacts are stored
+4. `.flightops/agent-crews/` — Project crew definitions for each phase (read the relevant crew file)
+```
+
+---
+
+## 3. Initialize the Project
+
+After adding the CLAUDE.md sections, run `/init-project` from mission-control to:
+
+1. Create the `.flightops/` directory with methodology references
+2. Configure the artifact system (files or Jira)
+3. Set up agent crew definitions
+4. Register the project in `/workspace/mission-control/projects.md`
+
+---
+
+## Quick Checklist for New Projects
+
+- [ ] Enable Mission Control for the project in Triple-C (auto-installs skills to `~/.claude/skills/`)
+- [ ] Add Flight Operations section to the project's `CLAUDE.md`
+- [ ] Run `/init-project` from mission-control
+- [ ] Add the project to `/workspace/mission-control/projects.md`
+- [ ] Add `.flightops/` to the project's `.gitignore` (if artifacts should not be committed) or commit it (if they should)

 ```
 
+The main area is driven by **one ordered tab strip** (`components/layout/MainTabs.tsx`) holding
+two tab kinds: `home:<projectId>` (Project Home) and `term:<sessionId>` (a terminal). There is no
+separate terminal tab bar. `activeSessionId` is derived from the active tab key, so exactly one
+thing is current at a time.
+
+### Keyboard Shortcuts
+
+Implemented in `hooks/useKeyboardShortcuts.ts` (document-level, capture phase):
+
+| Shortcut | Action |
+|---|---|
+| `Ctrl+T` | New Claude terminal for the current project (no-op unless it is running) |
+| `Ctrl+Shift+W` | Close the active tab |
+| `Ctrl+Tab` / `Ctrl+Shift+Tab` | Cycle tabs forward / backward |
+| `Ctrl+1` … `Ctrl+9` | Jump to the nth tab |
+
+`Ctrl+W` is deliberately **not** bound: it is readline's `kill-word`, used constantly in the
+terminal this app is built around. Terminal-scoped keys (`Ctrl+Shift+C`, `Ctrl+Shift+Alt+C`,
+`Ctrl+Shift+M`) are handled in `TerminalView.tsx`.
+
+### Project Home
+
+Clicking a project row in the sidebar opens **Project Home** in the main area — the per-project
+view, with tabs **Overview · Sessions · Automation · Config · Files**. The sidebar row itself is
+select-only (plus hover controls for start/stop and opening a terminal); it holds no configuration.
+Per-project configuration lives in the Config tab rather than in modals.
+
+| Tab | Contents |
+|---|---|
+| **Overview** | Permission mode control, sandbox/backend/Docker-access summary, capability tiles, recent sessions, scheduled tasks |
+| **Sessions** | Past Claude Code conversations read from the config volume, with **Resume** |
+| **Automation** | The container's `triple-c-scheduler` tasks — enable/disable, run now, read logs, remove, and completion notifications |
+| **Config** | Workspace (name, folders), Model (backend), Access (SSH, git, env vars, port mappings), Runtime (permission mode, sandbox, Docker access, Mission Control, instructions, Claude Code settings) |
+| **Files** | Browse, download and upload files inside the container |
+
+Container start/stop progress is reported inline (on the sidebar row and in the Project Home
+header) via the `container-progress` event, and failures surface as toasts. There is no blocking
+progress modal.
+
+### Permission Modes
+
+`PermissionMode` in `models/project.rs` replaces the old `full_permissions` boolean. Four states,
+mapped to CLI flags by `PermissionMode::cli_args()`:
+
+| Mode | Serialized | CLI args passed to `claude` |
+|---|---|---|
+| **Plan** | `plan` | `--permission-mode plan` |
+| **Default** | `default` | *(none)* |
+| **Accept Edits** | `acceptEdits` | `--permission-mode acceptEdits` |
+| **Bypass** | `bypass` | `--dangerously-skip-permissions` |
+
+`Project.permission_mode` is `Option<PermissionMode>`; `effective_permission_mode()` falls back to
+the legacy `full_permissions` flag (`true` → Bypass) for records written before the change. Changing
+the mode affects terminals opened **from then on** — a running `claude` process keeps the argv it
+was launched with.
+
+Scheduled tasks honour it too. The mode is injected as `TRIPLE_C_PERMISSION_MODE` (via
+`as_env_value()`) and written as the `triple-c.permission-mode` container label; the entrypoint
+snapshots it into `~/.claude/scheduler/.env`, and `container/triple-c-task-runner` translates it
+back into flags for its headless `claude -p` run. Because it travels as container env, a mode change
+only reaches the scheduler after the container is recreated on its next start (the label mismatch
+forces that).
+
+### Container Introspection (Capability Tiles)
+
+`list_container_capabilities` (`commands/inspect_commands.rs`) runs a read-only `find`/`jq` script
+inside a running container and returns counts plus item lists for **skills, agents, commands, hooks,
+plugins and MCP servers**, at user scope (`/home/claude/.claude`) and project scope
+(`/workspace/*/.claude`, `/workspace/*/.mcp.json`). Overview renders these as tiles.
+
+Triple-C does not create or edit any of them — Claude Code owns that configuration, and the tiles
+link out to a terminal where `/agents`, `/hooks`, `/plugins` and `/mcp` do the real work.
+
+### URL Relay (host browser)
+
+There is no browser and no display inside the container, so any CLI that wants to open a web page
+— `gh auth login`, `aws sso login`, `gcloud auth login`, `az login`, vendor CLIs, `xdg-open`,
+Python's `webbrowser` — simply fails. The URL relay forwards the *request* to the host, where the
+user's real browser is. Nothing is rendered or forwarded from the container; only the URL travels.
+It complements the Auth Bridge below: the relay gets the login page open, the bridge lets the
+callback land.
+
+**Transport — an OSC escape sequence, following `osc52-clipboard`.** `container/triple-c-open`
+writes
+
+```
+ESC ] 7777 ; open ; <base64(url)> BEL
+```
+
+to **`/dev/tty`**, and `TerminalView.tsx` picks it up with `term.parser.registerOscHandler(7777, …)`.
+`/dev/tty` rather than stdout is the whole point: the shim usually runs as a grandchild of
+something that captures its children's output (Claude Code invoking `gh auth login` as a tool
+call), so a printed sentinel line — the `###TRIPLE_C_SSO_REFRESH###` approach — would be swallowed
+by the intermediate process and never reach the terminal. A control sequence on the controlling
+terminal always arrives, and is invisible to terminals that don't know it. Base64 keeps a `;`,
+`BEL` or `ESC` inside the URL from breaking out of the sequence.
+
+**Container side** — `container/triple-c-open`, installed as `xdg-open`, `sensible-browser`,
+`www-browser`, `x-www-browser`, `gnome-open`, `gvfs-open`, `kde-open`, `open`, and exported as
+`$BROWSER`. Ubuntu 24.04 ships a real `/usr/bin/sensible-browser` (from `sensible-utils`), so that
+one is `dpkg-divert`ed rather than merely shadowed by a `/usr/local/bin` symlink; `www-browser` and
+`x-www-browser` are registered through `update-alternatives` and pinned with `--set`, because
+`sensible-browser` probes them by absolute path and because a later `apt install firefox` must not
+be able to steal them. `xdg-open` is diverted pre-emptively so installing `xdg-utils` inside the
+container cannot displace the relay. `BROWSER` is an image-level `ENV` — terminal sessions are
+separate `docker exec`s and never see what the entrypoint exported — and the entrypoint also
+forwards it into the scheduler's cron environment file.
+
+**No terminal attached** (cron-driven scheduled tasks, or a plain `docker exec` from outside
+Triple-C): there is no handshake and nothing to wait for, so the shim never blocks. The write to
+`/dev/tty` fails, and it prints the URL in plain text on its own line and exits 0 — which lands in
+the scheduler task log where a human can still act on it.
+
+**Security posture — the container is the untrusted side.** `app/src/lib/urlRelay.ts` validates
+before anything reaches `openUrl`: `http:`/`https:` only (`file:`, `javascript:`, `data:` and every
+registered protocol handler rejected), no embedded credentials, no control characters or
+whitespace, length-capped, and returned WHATWG-normalized so the prompt shows exactly what will
+open. Nothing opens automatically — the user confirms in the existing `UrlToast`, and prompts are
+rate-limited (5 per 10 s, repeats of the same URL collapsed) so a loop in the container cannot bury
+the UI.
+
+**Web terminal** — deliberately *not* a copy of the desktop behaviour. The browser there belongs to
+a remote viewer, possibly on a phone across a tunnel, so `terminal.html` renders the relayed URL as
+a tap-to-open link banner with the same scheme allowlist and rate limit, and opens nothing by
+itself. The OSC handler is registered regardless so the sequence is consumed rather than painted as
+garbage.
+
+### Auth Bridge
+
+Browser-based logins run *inside* a container (`claude login`, `aws sso login`, Concourse
+`fly login`) start an ephemeral HTTP listener on the container's loopback and expect the host
+browser's redirect to reach it. `auth_bridge/` closes that gap:
+
+- Listeners are discovered by parsing `/proc/net/tcp{,6}` every 2 seconds — the image ships no
+  `ss`, `netstat` or `lsof`. Only `TCP_LISTEN` rows bound to loopback are considered; wildcard
+  binds are deliberately ignored (that is the port-mappings feature's job).
+- Each discovered port is bound on the host at **the same port number**, on `127.0.0.1` (required)
+  and `[::1]` (best effort) — never a wildcard address. Node resolves `localhost` to IPv6 first, so
+  `claude login` often binds `::1` alone; the bridge follows the family it actually finds.
+- Traffic is carried in over the Docker API by an attached exec running `socat`, because container
+  IPs are not routable from the host on Docker Desktop.
+- Ports already covered by the project's port mappings are skipped, and a host port that is already
+  in use is reported as a conflict rather than fought over.
+
+Opt-in per project (`auth_bridge_enabled`, default `false`), purely host-side, so toggling it never
+recreates the container. The poller stops on its own when the container stops.
+
+**Security posture:** the host side binds loopback only. Everything reachable through it is an
+unauthenticated service inside the container, so widening those addresses would publish container
+internals to the LAN. Nothing else on the network can reach a bridged port.
+
+### Shared Claude Authentication Token
+
+Rather than running `claude login` in every container, `claude setup-token` can be run once
+(`commands/auth_token_commands.rs`). The flow borrows a running container, runs the CLI on a PTY,
+and the long-lived token it prints is stored in the OS keychain — it is never returned to the
+frontend and never logged. Streamed output passes through a chunk-boundary-safe redactor that masks
+anything resembling an `sk-ant-` secret.
+
+The token is injected as `CLAUDE_CODE_OAUTH_TOKEN` into every project where the backend is
+Anthropic, the project has not opted out (`use_shared_auth_token`, default `true`), and a token is
+actually stored. It is a reserved env key, so it cannot be hand-set as a custom variable.
+
+Rotation is tracked with a random id (not a hash of the token) mirrored into the
+`triple-c.claude-token-version` label — a hash in a `docker inspect`-readable label would be an
+offline verification oracle. Acquiring, rotating, revoking or opting out changes that label, which
+forces a container recreation on the next start; that is when a container picks the token up or has
+it cleared.
+
 ### Container Lifecycle
 
-1. **Create**: New container created with bind mounts, env vars, and labels
-2. **Start**: Container started, entrypoint remaps UID/GID, sets up SSH, configures Docker group, sets up MCP servers
-3. **Terminal**: `docker exec` launches Claude Code (or bash shell) with a PTY
-4. **Stop**: Container halted (filesystem persists in named volume); MCP containers stopped
-5. **Restart**: Existing container restarted; recreated if settings changed (detected via SHA-256 fingerprint)
-6. **Reset**: Container removed and recreated from scratch (named volume preserved)
+1. **Create**: New container created with bind mounts, named volumes, env vars, and labels
+2. **Start**: Container started, entrypoint remaps UID/GID, sets up SSH, configures Docker group, injects Claude Code settings, rebuilds the scheduler crontab
+3. **Terminal**: `docker exec` launches Claude Code (with the project's permission-mode flags) or a bash login shell, with a PTY
+4. **Stop**: Container halted (its filesystem layer and both named volumes persist)
+5. **Restart**: Existing container restarted; if any `triple-c.*` label no longer matches the project's settings, the container is committed to a snapshot image, removed, and recreated from that snapshot — so installed packages survive
+6. **Reset**: Container, snapshot image **and both named volumes** all removed, then recreated from the clean base image. `remove_project_volumes` deletes `triple-c-home-{projectId}` and `triple-c-claude-config-{projectId}`, so `~/.claude`, `~/.claude.json`, the OAuth login, installed skills, session transcripts and the scheduler's tasks are all lost.
 
 ### Mounts
 
 | Target in Container | Source | Type | Notes |
 |---|---|---|---|
-| `/workspace` | Project directory | Bind | Read-write |
-| `/home/claude/.claude` | `triple-c-claude-config-{projectId}` | Named Volume | Persists across container recreation |
+| `/workspace/<mount-name>` | Each configured project folder | Bind | Read-write; one per folder |
+| `/home/claude` | `triple-c-home-{projectId}` | Named Volume | Home directory; survives stop/start and recreation |
+| `/home/claude/.claude` | `triple-c-claude-config-{projectId}` | Named Volume | Nested inside the home volume; Docker gives the more specific mount precedence |
 | `/tmp/.host-ssh` | SSH key directory | Bind | Read-only; entrypoint copies to `~/.ssh` |
 | `/home/claude/.aws` | AWS config directory | Bind | Read-only; for Bedrock auth |
-| `/var/run/docker.sock` | Host Docker socket | Bind | If "Allow container spawning" is ON, or auto-enabled by stdio+Docker MCP servers |
+| `/var/run/docker.sock` | Host Docker socket | Bind | If "Allow container spawning" is ON |
+
+These two named volumes are the only ones a project owns. Both are removed by Reset and by project
+removal, and by nothing else.
 
 ### Authentication Modes
 
 Each project can independently use one of:
 
-- **Anthropic** (OAuth): User runs `claude login` inside the terminal on first use. Token persisted in the config volume across restarts and resets.
+- **Anthropic** (OAuth or shared token): either the shared `claude setup-token` token injected as `CLAUDE_CODE_OAUTH_TOKEN` (see below), or a per-container `claude login`. An interactive login's token lives in the config volume and survives container stop/start and recreation — but **not** a Reset, which deletes the volumes.
 - **AWS Bedrock**: Per-project AWS credentials (static keys, profile, or bearer token). SSO sessions are validated before launching Claude for Profile auth.
-- **Ollama**: Connect to a local or remote Ollama server via `ANTHROPIC_BASE_URL` (e.g., `http://host.docker.internal:11434`). Optional model override.
-- **LiteLLM**: Connect through a LiteLLM proxy gateway via `ANTHROPIC_BASE_URL` + `ANTHROPIC_AUTH_TOKEN` to access 100+ model providers. API key stored securely in OS keychain.
+- **Ollama**: Connect to a local or remote Ollama server via `ANTHROPIC_BASE_URL` (e.g., `http://host.docker.internal:11434`). Requires a model ID, and the model must be pulled (or used via Ollama cloud) before starting the container.
+- **llama.cpp**: Connect to a local or remote `llama-server` via `ANTHROPIC_BASE_URL` (e.g., `http://host.docker.internal:8080` — 8080 is `llama-server`'s default port). `ANTHROPIC_AUTH_TOKEN` is set to a placeholder; `llama-server` ignores it unless it was started with `--api-key`.
+- **OpenAI Compatible**: Connect through a gateway that implements the **Anthropic Messages API**, via `ANTHROPIC_BASE_URL` + `ANTHROPIC_AUTH_TOKEN`. API key stored securely in OS keychain.
 
-> **Note:** Ollama and LiteLLM support is best-effort. Claude Code is designed for Anthropic models, so some features (tool use, extended thinking, prompt caching, etc.) may not work as expected with non-Anthropic models behind these backends.
+> **The endpoint must speak the Anthropic Messages API.** Claude Code only ever sends
+> `POST /v1/messages?beta=true` in Anthropic Messages format to `ANTHROPIC_BASE_URL` — it never
+> speaks OpenAI's `/v1/chat/completions`. So a server that exposes *only* an OpenAI-compatible API
+> (plain vLLM, text-generation-inference, LocalAI, OpenRouter, …) will **not** work behind any of
+> these backends. What does work: **LiteLLM**, which exposes an Anthropic-shaped route, and
+> **Ollama** and **llama.cpp**, both of which implement `POST /v1/messages` natively — which is why
+> they get first-class backends of their own rather than going through a translation layer.
+
+#### Model alias variables
+
+The `opus` / `sonnet` / `haiku` / `fable` aliases in Claude Code resolve to Anthropic model IDs by
+default. Against a local server those IDs do not exist, so anything that uses an alias fails —
+most visibly the **background** calls (conversation titles, summaries), which use `haiku`.
+
+For every backend that points at a custom endpoint (Ollama, llama.cpp, OpenAI Compatible),
+Triple-C therefore sets all four:
+
+| Variable | Value |
+|---|---|
+| `ANTHROPIC_DEFAULT_OPUS_MODEL` | the backend's configured model ID |
+| `ANTHROPIC_DEFAULT_SONNET_MODEL` | the backend's configured model ID |
+| `ANTHROPIC_DEFAULT_HAIKU_MODEL` | the **Background model** override, else the configured model ID |
+| `ANTHROPIC_DEFAULT_FABLE_MODEL` | the backend's configured model ID |
+
+A local server usually serves exactly one model, so pointing every alias at it is the right
+default. If you run a second, smaller model for cheap background work, set **Background model**
+(Config → Model, and in global Backend settings) and only the Haiku alias moves.
+
+These are *not* set for the Anthropic or Bedrock backends, which reach servers that really do host
+the Anthropic model IDs. Triple-C manages all four names, so they cannot be set as custom
+environment variables. (`ANTHROPIC_SMALL_FAST_MODEL` is deprecated and is not used.)
+
+> **Note:** Ollama, llama.cpp and OpenAI Compatible support is best-effort. Claude Code is designed for Anthropic models, so some features (tool use, extended thinking, prompt caching, etc.) may not work as expected with non-Anthropic models behind these backends.

 If the Docker access setting is toggled after a container already exists, the container is automatically recreated on next start to apply the mount change. The named config volume (keyed by project ID) is preserved across recreation.
 
-### MCP Server Architecture
-
-Triple-C supports [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) servers as a Beta feature. MCP servers extend Claude Code with external tools and data sources.
-
-**Modes**: Each MCP server operates in one of four modes based on transport type and whether a Docker image is specified:
-
-| Mode | Where It Runs | How It Communicates |
-|------|--------------|---------------------|
-| Stdio + Manual | Inside the project container | Direct stdin/stdout (e.g., `npx -y @mcp/server`) |
-| Stdio + Docker | Separate MCP container | `docker exec -i <mcp-container> <command>` from the project container |
-| HTTP + Manual | External / user-provided | Connects to the URL you specify |
-| HTTP + Docker | Separate MCP container | `http://<mcp-container>:<port>/mcp` via Docker DNS on a shared bridge network |
-
-**Key behaviors**:
-- **Global library**: MCP servers are defined globally in the MCP sidebar tab and stored in `mcp_servers.json`
-- **Per-project toggles**: Each project enables/disables individual servers via checkboxes
-- **Auto-pull**: Docker images for MCP servers are pulled automatically if not present when the project starts
-- **Docker networking**: Docker-based MCP containers run on a per-project bridge network (`triple-c-net-{projectId}`), reachable by container name — not localhost
-- **Auto-detection**: Config changes are detected via SHA-256 fingerprints and trigger automatic container recreation
-- **Config injection**: MCP server configuration is written to `~/.claude.json` inside the container via the `MCP_SERVERS_JSON` environment variable, merged by the entrypoint using `jq`

 ### Mission Control Integration
 
-Optional per-project integration with [Flight Control](https://github.com/msieurthenardier/mission-control) — an AI-first development methodology. When enabled, the repo is cloned into the container, skills are installed, and workflow instructions are injected into CLAUDE.md.

+
+### Web Terminal (Remote Access)
+
+Triple-C includes an optional web terminal server for accessing project terminals from tablets, phones, or other devices on the local network. When enabled in Settings, an axum HTTP+WebSocket server starts inside the Tauri process, serving a standalone xterm.js-based terminal UI.
+
+- **URL**: `http://<LAN_IP>:7681?token=...` (port configurable)
+- **Authentication**: Token-based (auto-generated, copyable from Settings)
+- **Protocol**: JSON over WebSocket with base64-encoded terminal data
+- **Features**: Project picker, multiple tabs (Claude + bash sessions), mobile-optimized input bar, scroll-to-bottom button
+- **Session cleanup**: All terminal sessions are closed when the browser disconnects
+
+The web terminal shares the existing `ExecSessionManager` via `Arc`-wrapped stores — same Docker exec sessions, different transport (WebSocket instead of Tauri IPC events).
+
+### Speech-to-Text (Voice Mode)
+
+Triple-C includes optional speech-to-text powered by [Faster Whisper](https://github.com/SYSTRAN/faster-whisper) running in a separate Docker container. When enabled, a microphone button appears in the StatusBar whenever a terminal session is active.
+

+# Triple-C Roadmap — Claude Code Feature Parity
+
+**Date:** 2026-08-09 · **Baseline:** v0.3.0 · **Claude Code reference:** 2.1.226
+
+Companion to [DESIGN-REVIEW.md](DESIGN-REVIEW.md), which covers visual design and
+information architecture. This document covers *which Claude Code capabilities Triple-C
+should surface, and why.*
+
+---
+
+## Guiding principle
+
+> **Triple-C shows state and launches things. Claude Code edits its own config.**
+
+Triple-C's built-in MCP server management was removed in this cycle because Claude Code
+absorbed the capability natively (`claude mcp add/list/remove`, `.mcp.json`, `/mcp`).
+Hooks, skills, agents, plugins, output styles, and statusline are the same species: files
+under `.claude/` with first-class Claude Code TUIs. Building GUI form editors for them
+means losing the same race again.
+
+What Claude Code cannot do is what Triple-C uniquely owns: **the container boundary and
+what persists behind it** — the config volume, workspace mounts, lifecycle, the bundled
+scheduler, and the fleet view across many projects.
+
+---
+
+## Current coverage (v0.3.0)
+
+Triple-C sets exactly five `settings.json` keys, plus a sandbox block:
+
+| Key | Surfaced as |
+|---|---|
+| `tui` | TUI Mode select (`fullscreen`) |
+| `effort` | Effort Level select (`low`/`medium`/`high`) |
+| `autoScrollEnabled` | Auto-Scroll Disabled toggle |
+| `focusMode` | Focus Mode toggle |
+| `showThinkingSummaries` | Thinking Summaries toggle |
+| `sandbox.*` | Sandbox toggle (`enabled`, `enableWeakerNestedSandbox`, `allowUnsandboxedCommands`) |
+
+Plus four env feature flags — `CLAUDE_CODE_NO_FLICKER`, `CLAUDE_CODE_ENABLE_AWAY_SUMMARY`,
+`CLAUDE_CODE_SUBPROCESS_ENV_SCRUB`, `ENABLE_PROMPT_CACHING_1H` — and arbitrary user-set
+`CLAUDE_CODE_*` vars via the Env Vars modal.
+
+Also covered: per-project auth backends (Anthropic OAuth, Bedrock incl. SSO refresh,
+Ollama, OpenAI-compatible), user-level `CLAUDE.md` composition, `claude update` on every
+container start, terminal ergonomics (OAuth URL detection, OSC 52 clipboard, image paste,
+file drag-drop, STT), the web terminal, and workspace backup.
+
+---
+
+## Gap analysis
+
+### Committed for this cycle
+
+| # | Gap | Today | Plan |
+|---|---|---|---|
+| 1 | **Permission modes** | one boolean → `--dangerously-skip-permissions` | Four-state control (Plan / Default / Accept Edits / Bypass) → `--permission-mode`. Verified choices on 2.1.226: `acceptEdits`, `auto`, `bypassPermissions`, `manual`, `dontAsk`, `plan`. |
+| 2 | **Session resume** | none | List sessions from the config volume; `[Resume]` opens a terminal on `claude --resume <id>`. |
+| 3 | **Capability inventory** | none | Read-only counts + names for skills / agents / hooks / plugins / commands / native MCP servers. Deep-link to the terminal to manage. |
+| 4 | **Automation** | `triple-c-scheduler` ships in every container with *zero* UI | Task list, cron editor, run-now, logs, notification badges. |
+| 5 | **Container auth handoff** | manual code paste | See "Authentication handoff" below — design decision pending. |
+
+### Deliberately skipped
+
+Status line builder · output-styles editor · hook *editors* · checkpoint/rewind browser ·
+plugin marketplace browser. Each is niche, natively handled by Claude Code's own TUI, or a
+settings-editor trap. Surface counts and deep-link instead.
+
+### Not yet scheduled
+
+- Granular `permissions.allow` / `ask` / `deny` rules and `additionalDirectories`
+- Sandbox detail settings (`filesystem.allowRead/allowWrite`, `allowedDomains`,
+  `excludedCommands`) — currently documented for hand-editing via `SANDBOX_INSTRUCTIONS`
+- Project-level `.claude/settings.json` vs user-level settings hierarchy
+- A model picker. **Note:** the only model strings in the app today are stale placeholders
+  (`anthropic.claude-sonnet-4-20250514-v1:0` in `AwsSettings.tsx` and `ProjectCard.tsx`,
+  `qwen3.5:27b`, `gpt-4o / gemini-pro / etc.`). These are free-text placeholders, not
+  dropdowns, but they should be refreshed to current model identifiers regardless.
+- The container's settings.json merge is **shallow** (`jq -s '.[0] * .[1]'`), so a
+  user-authored nested block such as `sandbox.filesystem.allowWrite` is replaced wholesale
+  on every container start. Worth deepening to `*` recursive merge.
+
+---
+
+## Authentication handoff
+
+**Goal:** stop making users hand-copy an auth code into every container.
+
+**Constraint discovered during research:** `claude login`'s callback server uses an
+**ephemeral port** and its redirect URI is **not configurable** for the main login flow
+(`--callback-port` and `oauth.callbackPort` apply to *MCP server* OAuth only). So a design
+that pre-assigns each container a fixed callback port and routes to it cannot work as
+stated — there is no fixed port to route.
+
+There is also a known container gotcha: on Linux, Node resolves `localhost` to IPv6 first,
+so the callback server may bind `[::1]:PORT` only and be unreachable over IPv4
+([anthropics/claude-code#44844](https://github.com/anthropics/claude-code/issues/44844)).
+
+Two viable options:
+
+### Option A — long-lived token injection (simple)
+
+`claude setup-token` (verified present on 2.1.226: *"Set up a long-lived authentication
+token (requires Claude subscription)"*) returns a ~1-year OAuth token. Triple-C runs it in
+a running container, stores the token in the OS keychain via the existing `secure.rs`, and
+injects `CLAUDE_CODE_OAUTH_TOKEN` into every container on the Anthropic backend.
+
+**Correction to an earlier assumption in this document.** `setup-token` does *not* start a
+loopback callback listener, so it does not need the Auth Bridge. Verified by running it
+under a pty: its `redirect_uri` is Anthropic-hosted
+(`https://platform.claude.com/oauth/code/callback`), the user copies a code off that page,
+and the CLI blocks at a `Paste code here if prompted >` prompt on **stdin**. A stdin path
+is therefore mandatory — the flow cannot complete without one.
+
+- No routing, no ports, no proxy.
+- One auth event covers every project.
+- Cost: small. Reuses existing keychain and env-injection plumbing.
+- Limits: token is subscription-scoped and expires annually; per the docs a `setup-token`
+  token cannot drive Remote Control sessions or claude.ai connector fetches.
+
+Change detection uses a **random rotation id** in the `triple-c.claude-token-version`
+label, not a hash of the token. Labels are readable by anything that can run
+`docker inspect`, so a hash would be an offline verification oracle — given a candidate
+token you could confirm it. A presence boolean would instead miss rotations and silently
+leave containers on a stale token.
+
+### Option B — the Auth Bridge (general loopback-callback bridge)
+
+Option A only solves Claude Code. The same problem affects every CLI that authenticates by
+starting a temporary loopback listener and opening a browser at a URL that redirects back
+to it — Concourse `fly login` (random loopback port serving `/auth/callback`),
+`aws sso login`, and many others. Inside a container the host browser cannot reach that
+listener, so login stalls.
+
+Because the ports are ephemeral and unconfigurable, nothing can be pre-assigned. The bridge
+**discovers** listeners instead:
+
+1. While enabled for a running project, poll the container for loopback TCP listeners by
+   reading `/proc/net/tcp` and `/proc/net/tcp6` over `docker exec` — no dependency on
+   `ss`/`netstat`/`lsof`, which aren't guaranteed in the image.
+2. For each newly-appeared loopback listener, bind **the same port on the host's
+   `127.0.0.1`** (never `0.0.0.0` — that would expose container internals to the LAN).
+3. Proxy each accepted connection into the container over the Docker API via
+   `socat - TCP:127.0.0.1:<port>` (socat already ships in the image), reusing the existing
+   attached-exec streaming in `docker/exec.rs`. Going through the Docker API rather than a
+   container IP keeps this working on Docker Desktop, where container IPs are not routable
+   from the host.
+4. Fall back to `TCP6:[::1]:<port>` when the listener appeared only on IPv6 — on Linux,
+   Node resolves `localhost` to IPv6 first, so `claude login` frequently binds `::1` only
+   ([anthropics/claude-code#44844](https://github.com/anthropics/claude-code/issues/44844)).
+5. Tear down when the listener vanishes, the container stops, the bridge is disabled, or
+   the app exits. Ports already covered by the project's explicit port mappings are skipped;
+   host-side conflicts are reported rather than silently swallowed.
+
+Opt-in per project (`auth_bridge_enabled`, default off), since it makes container-internal
+loopback services reachable from the host.
+
+**Plan:** ship **A** for Claude Code specifically — it removes the pain for the common case
+at a fraction of the cost — and **B** as the general mechanism covering every other CLI.
+They compose: A means most users never trigger a browser login at all; B catches AWS SSO,
+Concourse, and anything else that needs a real callback.
+
+---
+
+## Sequencing
+
+**Phase 0 — done.** Remove MCP (frontend, backend, entrypoint, docs) with a self-healing
+migration for containers created against the old per-project Docker network.
+
+**Phase 1 — foundations.** Permission modes end-to-end (including the scheduler bug fix
+below). Read-only introspection backend: sessions, capabilities, scheduler.
+
+**Phase 2 — Tier-1 polish.** Focus rings, contrast fixes, real buttons, inline start/stop
+progress, status labels, onboarding welcome screen, shared accessible `<Modal>`.
+
+**Phase 3 — Project Home.** Move project config out of the sidebar card into a tabbed
+main-area view (Overview / Sessions / Automation / Config), dissolving the modal pile and
+splitting the 1,257-line `ProjectCard`.
+
+**Phase 4 — authentication handoff.** Option A, then evaluate B.
+
+**Phase 5 — Library.** Global skills/agents/commands with per-project enable, synced into
+the config volume by the entrypoint. Generalizes the pattern the MCP tab was reaching for.
+
+---
+
+## Bugs found during this review
+
+1. **Scheduled tasks ignore the project's permission setting.**
+   `container/triple-c-task-runner:69` runs
+   `claude -p "$PROMPT" --dangerously-skip-permissions` unconditionally, regardless of the
+   project's Full Permissions toggle. Being fixed as part of Phase 1.
+
+2. **Docs claim Reset preserves credentials; it does not.**
+   `rebuild_project_container` calls `remove_project_volumes`, which deletes both
+   `triple-c-home-{id}` (holding `~/.claude.json`) and `triple-c-claude-config-{id}`
+   (holding `~/.claude`). README.md, HOW-TO-USE.md, and CLAUDE.md all still state that
+   OAuth tokens survive a Reset. Pre-existing; not yet corrected.
+
+3. **An invalid cron expression silently unscheduled every task.** Found while adding
+   task creation to the Automation tab, and the most serious bug in this review.
+   `triple-c-scheduler` never validated `--schedule`, and `rebuild_crontab` regenerates the
+   *entire* crontab and pipes it to `crontab`, which rejects the whole file if any single
+   line is malformed — with the error discarded by `2>/dev/null || true`. So one bad
+   schedule silently unscheduled every other task in the container, reporting success.
+   Reproduced directly. This mattered because the global CLAUDE.md instructs Claude to use
+   this CLI, so Claude itself could trigger it. Fixed at the root: `add` now validates the
+   expression and exits non-zero, and `rebuild_crontab` reports a rejected crontab instead
+   of swallowing it. The Rust `add_scheduled_task` command validates independently.
+
+4. **Reset was destructive with no confirmation.** It deletes both volumes — the login,
+   installed skills, all session transcripts — from a single unconfirmed click, while the
+   comparably destructive Remove already confirmed. Now gated by a dialog that names each
+   loss. Fixed.
+
+5. **Cancelling authentication did not cancel.** Fixed — see the handoff section above.
+
+6. **Stale model placeholders** — see "Not yet scheduled" above.
+
+7. **Silent save failures.** Project config saves on blur; failures went only to
+   `console.error`. Fixed in Phase 3 — `useProjectSave` now renders a
+   Saved / Saving / Save failed indicator and raises a toast.
+
+---
+
+## Known gaps left by Phase 2–3
+
+- **Editing a scheduled task changes its id.** `triple-c-scheduler` has no `edit`
+  subcommand, and hand-editing its JSON behind its back would desync the crontab, so edit is
+  implemented as add-then-remove. The add runs first, so a rejected edit leaves the original
+  intact. The task gets a new id and its older logs stay under the old one; the editor says
+  so before saving.
+- **`open_terminal_session` takes no command argument.** "Resume session" and
+  "Manage in terminal" therefore open a bash tab and *type* the command after a
+  fixed prompt delay. It works, but it is timing-dependent and will misfire on a
+  slow container start. The fix is a `command: Option<String>` parameter on the
+  Tauri command so the exec launches the process directly.
+- **Uptime is observed, not reported.** `get_container_info` returns a status enum
+  with no start time, so Project Home records "running since" when the app *sees*
+  the transition. A container already running when the app launches shows
+  `● Running` with no elapsed time. Surfacing Docker's `State.StartedAt` would fix it.
+- **`lucide-react` was not adopted** (DESIGN-REVIEW Tier-1 #9) — no package-registry
+  access in the build environment used for this cycle. The existing inline SVGs and
+  text glyphs remain.
+- **The tab strip stayed in the TopBar** rather than moving onto the terminal panel's
+  top edge. DESIGN-REVIEW §A6 asks for the move but its own §B2 layout diagram puts
+  the tabs in the TopBar; the diagram won. Worth revisiting.
+- **`Ctrl+Shift+W`, not `Ctrl+W`, closes a tab.** Plain `Ctrl+W` is readline's
+  `kill-word`, used constantly inside the terminal this app is built around;
+  intercepting it globally would break word-erase in every shell.

+- **STT mic and "Jump to Current" live in the global `StatusBar`, not per-terminal overlays.** There is a single `useSTT` instance in `App.tsx` bound to the active session. `Ctrl+Shift+M` routes through the Zustand store (`sttToggle`).
+- **Recording is pinned to where it started.** The STT transcript targets `recordingSessionIdRef` (the session recording began in), **not** the live active session — switching tabs mid-recording must not misroute the transcript.
+- **"Jump to Current" state is written only by the active terminal.** The active `TerminalView` surfaces `terminalAtBottom` and `scrollActiveToBottom` through the store; only the active terminal writes them, and they are cleared on its unmount.
+- **Set store function values via object-merge, not the updater form** — `set({ fn: value })`, not `set(state => ...)` — when publishing action callbacks (like `scrollActiveToBottom`) into the Zustand store.

An axum HTTP+WebSocket server runs inside the Tauri process, sharing the same `ExecSessionManager` via `Arc`-wrapped stores. The WebSocket uses a JSON protocol with base64-encoded terminal data.

+1. **First start**: A new container is created with bind mounts, named volumes, environment variables, and labels. The entrypoint remaps UID/GID, configures SSH and git, rebuilds the scheduler crontab, then runs `sleep infinity` to keep the container alive.
+2. **Terminal open**: `docker exec` launches `claude` with a PTY in the running container, with the permission-mode flags from `PermissionMode::cli_args()` (or `bash -l` for a shell session).
 3. **Stop**: `docker stop` halts the container but preserves its filesystem. Any packages Claude installed via `apt`, `pip`, `cargo`, etc. survive.
-4. **Restart**: `docker start` resumes the existing container. All installed tools and configuration persist.
-5. **Reset**: The container is removed and recreated from the image. This is a clean slate — the nuclear option when the container state is corrupted.
+4. **Restart**: `docker start` resumes the existing container — unless `container_needs_recreation()` finds a `triple-c.*` label that no longer matches the project's settings, in which case the container is committed to a snapshot image (`triple-c-snapshot-{projectId}:latest`), removed, and recreated from that snapshot. Installed tools survive; the named volumes are untouched.
+5. **Reset**: `rebuild_project_container` closes live exec sessions, removes the container, removes the snapshot image, calls `remove_project_volumes` to delete **both** named volumes, then starts fresh from the clean base image.
 
-The `.claude` configuration directory uses a **named Docker volume** (`triple-c-claude-config-{projectId}`) so OAuth tokens from `claude login` persist even across container resets.
+Two named volumes exist per project and they are the only ones it owns:
+
+| Volume | Mount point | Purpose |
+|---|---|---|
+| `triple-c-home-{projectId}` | `/home/claude` | Home directory — `~/.claude.json`, `~/.local`, `~/.ssh`, `~/.aws` |
+| `triple-c-claude-config-{projectId}` | `/home/claude/.claude` | Claude Code config: OAuth credential, settings, skills/agents/commands, session transcripts, scheduler state. Nested inside the home volume; Docker gives the more specific mount precedence. |
+
+`remove_project_volumes` names those two volumes explicitly (no prefix sweep) and is called from
+exactly two places: `remove_project` and `rebuild_project_container`. Ordinary container removal
+passes `v: false`, so stop/start and recreation never touch the volumes — **only Reset and project
+removal delete them.** A Reset therefore destroys the `claude login` credential, installed skills,
+session transcripts and scheduled tasks; it does not touch host bind mounts, the project record, or
+host keychain secrets.
+
+### Permission Modes
+
+`PermissionMode` (`models/project.rs`) is a four-state enum replacing the earlier `full_permissions`
+boolean. It reaches Claude Code by two different routes:
+
+| Mode | `cli_args()` — interactive terminals | `as_env_value()` — scheduler |
+|---|---|---|
+| `Plan` | `--permission-mode plan` | `plan` |
+| `Default` | *(no flag)* | `default` |
+| `AcceptEdits` | `--permission-mode acceptEdits` | `acceptEdits` |
+| `Bypass` | `--dangerously-skip-permissions` | `bypass` |
+
+`Project.permission_mode` is `Option<PermissionMode>`, and `effective_permission_mode()` resolves
+`None` from the legacy `full_permissions` flag, so records written before the change keep behaving
+the same way.
+
+**Interactive path.** `build_terminal_cmd()` evaluates `cli_args()` when a session is created, so
+the flags are fixed for the life of that `claude` process. Changing the mode affects terminals
+opened afterwards, not running ones. The same applies to `resume_session_command`, which builds
+`claude <flags> --resume <id>` server-side.
+
+**Scheduler path.** Cron jobs run with a minimal environment, so the mode travels as
+`TRIPLE_C_PERMISSION_MODE` in the container's env; the entrypoint snapshots the allowlisted
+variables into `~/.claude/scheduler/.env`, and `triple-c-task-runner` sources that file and maps the
+value back to flags for its `claude -p` run. Container env can only change at create time, so
+`container_needs_recreation()` compares a `triple-c.permission-mode` label and forces a recreation
+on the next start. A mode change therefore reaches new terminals immediately but the scheduler only
+after a stop/start. `TRIPLE_C_PERMISSION_MODE` is a reserved env key so it cannot be hand-set.
 
 ### Authentication Modes
 
-Each project independently chooses one of two authentication methods:
+Each project independently chooses one backend:
 
-| Mode | How It Works | When to Use |
+| Backend | How It Works | When to Use |
 |------|-------------|-------------|
-| **Anthropic (OAuth)** | User runs `claude login` or `/login` inside the terminal. OAuth URL opens in host browser via URL detection. Token persists in the `.claude` config volume. | Default — personal and team use |
-| **AWS Bedrock** | Per-project AWS credentials (static keys, profile, or bearer token) injected as env vars. `~/.aws` config optionally bind-mounted read-only. | Enterprise environments using Bedrock |
+| **Anthropic** | Either the shared `CLAUDE_CODE_OAUTH_TOKEN` injected from the OS keychain, or a per-container `claude login` whose credential persists in the `.claude` config volume. The OAuth URL opens in the host browser via URL detection. | Default — personal and team use |
+| **AWS Bedrock** | Per-project AWS credentials (static keys, named profile, or bearer token) injected as env vars. `~/.aws` config optionally bind-mounted read-only; SSO sessions are validated before launching Claude for profile auth. | Enterprise environments using Bedrock |
+| **Ollama** | `ANTHROPIC_BASE_URL` points at an Ollama server; `ANTHROPIC_AUTH_TOKEN` is set to the placeholder `ollama`. Ollama implements `POST /v1/messages` natively. | Local models (best-effort) |
+| **llama.cpp** | `ANTHROPIC_BASE_URL` points at a `llama-server` (default port 8080); `ANTHROPIC_AUTH_TOKEN` is set to the placeholder `llama.cpp`, which `llama-server` ignores unless started with `--api-key`. `llama-server` implements `POST /v1/messages` and `/v1/messages/count_tokens` natively. | Local models (best-effort) |
+| **OpenAI Compatible** | `ANTHROPIC_BASE_URL` plus `ANTHROPIC_AUTH_TOKEN` point at a gateway. **Despite the name, the endpoint must implement the Anthropic Messages API** — Claude Code only ever sends `POST /v1/messages?beta=true`, never `/v1/chat/completions`. LiteLLM works; a bare OpenAI-only server does not. | Anthropic-shaped gateways (best-effort) |
+
+#### Model aliases on custom endpoints
+
+`Backend::uses_custom_endpoint()` (Ollama, llama.cpp, OpenAI Compatible) gates the emission of
+`ANTHROPIC_DEFAULT_{OPUS,SONNET,HAIKU,FABLE}_MODEL`, computed by
+`docker::container::compute_model_aliases`. All four default to the backend's resolved model id;
+each backend carries an optional `haiku_model_id` override, because the Haiku alias is what Claude
+Code uses for background work. Anthropic and Bedrock emit none of them and keep Claude Code's
+defaults; the four names are in `MANAGED_AUTH_KEYS`, so switching away from a custom endpoint
+blanks the values baked into the snapshot image. The resolved alias set is folded into each
+backend's `triple-c.*-fingerprint` label, since `container_needs_recreation` is label-based and
+never diffs env. `ANTHROPIC_SMALL_FAST_MODEL` is deprecated and unused.
+
+### Shared Claude Authentication Token
+
+`commands/auth_token_commands.rs` runs `claude setup-token` on a PTY inside a running container.
+Contrary to the loopback pattern most CLI logins use, `setup-token` redirects to an Anthropic-hosted
+page and then blocks on a stdin paste prompt, so the flow needs a way to feed the pasted code back
+in — hence `submit_claude_token_code`. The flow is single-flight (the token is global, so two
+concurrent logins would race to overwrite each other's keychain entry) and times out after 15
+minutes.
+
+- **Storage** — the OS keychain, under a dedicated service name; the token is never returned to the
+  frontend, never written to a log, and no command accepts or returns it.
+- **Redaction** — streamed output is stripped of ANSI sequences and passed through a stateful
+  redactor that masks anything matching `sk-ant-` with a plausible body, withholding any tail that
+  could still grow into a secret across a chunk boundary.
+- **Injection** — `CLAUDE_CODE_OAUTH_TOKEN` is set only when the backend is Anthropic, the project
+  has not opted out (`use_shared_auth_token`, default `true`), and a non-blank token is stored. When
+  those conditions do not hold, the variable is explicitly set to empty rather than omitted, so a
+  value baked into a snapshot image by `docker commit` is actively cleared.
+- **Rotation** — a random UUID minted on each store is mirrored into the
+  `triple-c.claude-token-version` label. It is deliberately *not* a hash of the token: labels are
+  readable by anything that can run `docker inspect`, and a hash would be an offline verification
+  oracle. A label mismatch forces container recreation on the next start, which is when a container
+  picks up or loses the token.
+
+### Auth Bridge
+
+CLIs that log in through a browser (`claude login`, `aws sso login`, `fly login`) start an ephemeral
+HTTP listener on an unpredictable loopback port and hand the provider a `http://localhost:<port>/…`
+redirect. Run inside a container, that listener is unreachable from the host browser and nothing can
+be pre-published at container-creation time. `auth_bridge/` bridges it at runtime:
+
+- **Discovery** (`proc_net.rs`) — a `docker exec` reads `/proc/net/tcp` and `/proc/net/tcp6` every
+  two seconds. The image ships no `ss`, `netstat` or `lsof`. Only rows in state `0A` (`TCP_LISTEN`)
+  bound to loopback are kept; wildcard binds are ignored on purpose, since publishing those is the
+  port-mappings feature's job.
+- **Family handling** — a `::1`-only listener genuinely cannot be reached over `127.0.0.1`, and Node
+  resolves `localhost` to IPv6 first on Linux, so `claude login` frequently binds `::1` alone. The
+  socat target follows the family actually observed; IPv4-mapped rows in `/proc/net/tcp6` are
+  treated as IPv4.
+- **Host bind** (`tunnel.rs`) — the same port number is bound on the host: `127.0.0.1` is required,
+  `[::1]` is best-effort. **The host side binds loopback only, never a wildcard address** —
+  everything behind it is an unauthenticated in-container service that bound loopback precisely
+  because it expected to be unreachable.
+- **Transport** — each accepted connection is proxied by an attached exec running
+  `socat - TCP:127.0.0.1:<port>`, because container IPs are not routable from the host under Docker
+  Desktop. It goes through the same `create_attached_exec()` helper as terminal sessions, with
+  `tty: false` so socat's stderr is demultiplexed away from the proxied byte stream.
+- **Policy** — ports appearing in the project's port mappings are skipped, and a host bind failure
+  is recorded as a conflict and retried later rather than fought over.
+- **Lifecycle** — opt-in per project (`auth_bridge_enabled`, default `false`). It is purely
+  host-side, so it deliberately has no container-recreation label. The poller stops itself when the
+  project is gone, the flag is cleared, or the container is no longer running, and `stop()` awaits
+  it so host ports are provably released.
+
+### Container Introspection
+
+`list_container_capabilities` (`commands/inspect_commands.rs`) executes a read-only shell script in
+a running container and returns counts and item lists for skills, agents, commands, hooks, plugins
+and MCP servers, across user scope (`/home/claude/.claude`) and project scope
+(`/workspace/*/.claude`, `/workspace/*/.mcp.json`). Everything is computed in-container with
+`find`/`awk`/`jq`; only the JSON summary crosses the wire, and a stopped container yields zeros
+rather than an error.
+
+The script writes nothing. Claude Code owns this configuration and has its own tooling for it
+(`/agents`, `/hooks`, `/plugins`, `/mcp`); Triple-C surfaces counts and opens a terminal rather than
+rebuilding those editors as forms. `list_claude_sessions` and the scheduler commands
+(`list_scheduled_tasks`, `get_scheduled_task_log`, `set_scheduled_task_enabled`,
+`run_scheduled_task_now`, `remove_scheduled_task`, `clear_scheduler_notifications`) live in the same
+module; the mutating ones shell out to `triple-c-scheduler` rather than editing its state files.
+
+### Main-Area Tab Model
+
+The frontend keeps a single ordered `tabOrder` array in the Zustand store holding two tab kinds,
+`home:<projectId>` and `term:<sessionId>`, rendered by `components/layout/MainTabs.tsx`.
+`activeSessionId` is *derived* from `activeTabKey`, so exactly one thing is current and a Project
+Home tab and a terminal cannot both claim focus. Project configuration is a main-area view
+(`components/projects/home/`), not a modal; the sidebar row is select-only.

+//! Auth Bridge — lets browser-based OAuth logins run by CLIs *inside* a
+//! container complete against the browser on the *host*.
+//!
+//! ## The problem
+//!
+//! `claude login`, Concourse's `fly login`, `aws sso login` and friends all use
+//! the same pattern: start a throwaway HTTP listener on a random loopback port,
+//! then open a browser at a provider URL whose redirect points back to
+//! `http://localhost:<that port>/callback`. Run inside a container, the listener
+//! is on the *container's* loopback, the browser is on the *host's*, and the
+//! callback goes nowhere — the login just hangs. The ports are ephemeral and not
+//! configurable, so nothing can be pre-published at container creation time.
+//!
+//! ## The mechanism
+//!
+//! While the bridge is enabled for a running project, poll the container every
+//! [`POLL_INTERVAL`] for loopback TCP listeners (see [`proc_net`]). For each one
+//! that appears, bind the *same* port on the host's loopback and proxy each
+//! accepted connection into the container over `docker exec … socat` (see
+//! [`tunnel`]). When the in-container listener goes away, drop the host
+//! listener. The host and container therefore agree on the port number, which is
+//! the whole trick: the redirect URL the provider was given resolves correctly
+//! on both sides.
+//!
+//! ## Lifecycle and teardown
+//!
+//! One poller task per project. It is the only thing that owns
+//! [`PortForward`]s, and it always tears them down on its way out, so every way
+//! the bridge can end funnels through the same code:
+//!
+//! | Trigger | Path |
+//! |---|---|
+//! | Bridge disabled | `set_auth_bridge_enabled(false)` → [`AuthBridgeManager::stop`] |
+//! | Container stopped via UI | `stop_project_container` → [`AuthBridgeManager::stop`] |
+//! | Container stopped/died another way | poller's own `is_container_running` check → loop exits |
+//! | Project deleted | `remove_project` → [`AuthBridgeManager::stop`]; also the poller's `store.get()` check |
+//! | Container rebuilt | `rebuild_project_container` → stop, then start re-arms it |
+//! | App exit | window `CloseRequested` → [`AuthBridgeManager::stop_all`] |
+//!
+//! [`AuthBridgeManager::stop`] awaits the poller, so host ports are provably
+//! released before it returns. As a backstop for any path that skips all of the
+//! above (a panicking poller, an aborted task), `PortForward`'s [`Drop`] aborts
+//! the accept loop, which drops the socket.

+//! Discovery of loopback TCP listeners by parsing `/proc/net/tcp` and
+//! `/proc/net/tcp6` from inside the container.
+//!
+//! ## Why /proc and not `ss`
+//!
+//! The container image (`container/Dockerfile`) ships neither `iproute2` (`ss`)
+//! nor `net-tools` (`netstat`) nor `lsof`. `/proc/net/tcp{,6}` is part of procfs
+//! and needs no package at all, so discovery works in the stock image and in any
+//! snapshot derived from it.
+//!
+//! ## Wire format
+//!
+//! Both files are fixed-column text with a header line:
+//!
+//! ```text
+//!   sl  local_address rem_address   st tx_queue rx_queue tr tm->when retrnsmt   uid  timeout inode
+//!    0: 0100007F:8707 00000000:0000 0A 00000000:00000000 00:00000000 00000000     0        0 27764798 1 ...
+//! ```
+//!
+//! Only two columns matter: `local_address` (index 1) and `st` (index 3).
+//! `st == 0A` is `TCP_LISTEN`; every other state is a connection, not a listener.
+//!
+//! ## Hex and endianness
+//!
+//! `local_address` is `<address>:<port>`, both hex, but they are *not* encoded
+//! the same way:
+//!
+//! * The **port** is a plain big-endian `%04X` — `8707` is 34567.
+//! * The **address** is printed as one `%08X` per 32-bit word *in host byte
+//!   order*, which is little-endian on every platform this app targets. So each
+//!   8-hex-digit group must be parsed as a `u32` and then expanded with
+//!   [`u32::to_le_bytes`] to recover the address bytes in network order:
+//!   `0100007F` → `0x0100007F` → `[7F, 00, 00, 01]` → `127.0.0.1`.
+//!
+//! IPv4 rows have one such group (8 hex digits); IPv6 rows have four (32 hex
+//! digits), each converted independently, in order, to fill the 16 address
+//! bytes. `::1` is therefore `00000000000000000000000001000000`, and the
+//! IPv4-mapped `::ffff:127.0.0.1` is `0000000000000000FFFF00000100007F`.
+//!
+//! ## What counts as loopback
+//!
+//! Only `127.0.0.0/8` and `::1` (plus IPv4-mapped loopback, reported as v4).
+//! A `0.0.0.0` or `::` listener is a service deliberately published to the
+//! outside world — that is the port-mappings feature's job, not the auth
+//! bridge's — so those rows are dropped.

+//! Playwright is **not** in the container image — it is installed by the user or
+//! by Claude, into whichever `node_modules` happens to be in scope. So detection
+//! has to be done inside the container, at the moment the pane is opened, and it
+//! has to produce an *actionable* answer when the pieces are missing: the pane's
+//! one unforgivable failure mode would be an unexplained spinner.
+//!
+//! Three things must line up:
+//!
+//! 1. **`playwright-core`** (directly, or via `playwright`, which re-exports it),
+//! 2. at a version whose `Browser` exposes **`bind()`** — the live-dashboard API
+//!    that publishes a browser for a viewer to attach to, and
+//! 3. **`@playwright/cli`**, which ships the viewer UI itself.
+//!
+//! Discovery of published browsers is local-filesystem based (a cache directory
+//! plus a unix-socket singleton in the temp dir), which is exactly why the viewer
+//! has to run *in the container* next to the browsers rather than on the host.

+//! Browser view — watch, and take over, the browser Claude is driving.
+//!
+//! ## What is actually being watched
+//!
+//! Playwright ships a live dashboard. A script inside the container calls
+//! `await browser.bind('claude')`, which publishes a descriptor for the running
+//! browser into `~/.cache/ms-playwright/b/`; `@playwright/mcp` does this for you.
+//! `playwright-cli show --host 127.0.0.1 --port <p>` then serves a React viewer
+//! that watches that directory, connects to the published browser, and gives you
+//! a CDP screencast with full mouse and keyboard takeover — all of which works
+//! with `headless: true`, which is the only thing that could work in a container.
+//!
+//! Discovery is *local filesystem*, so the viewer has to run in the same
+//! container as the browsers. There is nothing a host-side viewer could see.
+//!
+//! ## Getting it onto the screen safely
+//!
+//! ```text
+//!   webview <iframe>                    host                          container
+//!   ────────────────                    ────                          ─────────
+//!   http://127.0.0.1:47820/index.html
+//!            ?ws=…&token=…   ────►  BrowserViewProxy   ──socat exec──►  playwright-cli show
+//!                                   (token gate)          (Docker API)   127.0.0.1:39321
+//! ```
+//!
+//! The proxy is the *only* host-bound socket, and it authenticates before a byte
+//! reaches the container — see [`proxy`] for the gate, and for why the auth
+//! bridge's unauthenticated [`PortForward`](crate::auth_bridge::tunnel::PortForward)
+//! is deliberately not used to carry this port. The container-side viewer port is
+//! additionally *reserved* with
+//! [`crate::auth_bridge::RESERVED_CONTAINER_PORTS`], so that a project which
+//! also has the auth bridge on cannot end up with the viewer mirrored onto the
+//! host a second time, ungated.
+//!
+//! ## Lifecycle
+//!
+//! Off by default and per-project opt-in, exactly like `auth_bridge_enabled`.
+//! One supervisor task per session owns the proxy and the viewer process, and it
+//! is the only thing that tears them down, so every way a session can end funnels
+//! through one code path:
+//!
+//! | Trigger | Path |
+//! |---|---|
+//! | Turned off in the UI | `set_browser_view_enabled(false)` → [`BrowserViewManager::stop`] |
+//! | Container stopped, by the UI or otherwise | supervisor's `is_container_running` check |
+//! | Project deleted | supervisor's `store.get()` check |
+//! | Container rebuilt | old container stops → supervisor exits; the new one is not auto-started |
+//! | Viewer died in the container | supervisor's periodic HTTP liveness probe |
+//! | App exit | [`BrowserViewManager::stop_all`] |
+//!
+//! [`BrowserViewManager::stop`] awaits the supervisor, so the host port is
+//! provably released before it returns.
+//!
+//! One honest gap, verified rather than assumed: `playwright-cli show` is only
+//! a launcher — the dashboard it starts reparents to PID 1 and survives the
+//! exec that spawned it. Every ordinary teardown path above calls
+//! [`kill_dashboard`], which does stop it, but a *hard* app crash leaves the
+//! dashboard running inside the container until the container stops. That
+//! orphan is reachable on container loopback only: the host-side port dies with
+//! the app, and [`crate::auth_bridge::RESERVED_CONTAINER_PORTS`] is a constant
+//! precisely so the bridge will not mirror an orphan the next time the app
+//! starts. The next [`BrowserViewManager::start`] reclaims it.

+//! The host-side, token-gated front door for one project's Playwright viewer.
+//!
+//! ## Why this is not `PortForward` on its own
+//!
+//! [`crate::auth_bridge::tunnel::PortForward`] mirrors a container loopback port
+//! onto the *same* host loopback port with **no authentication at all**. That is
+//! the right trade for the auth bridge — the things it exposes are short-lived
+//! OAuth callback listeners whose whole purpose is to receive one unauthenticated
+//! request — but it is the wrong trade here. The Playwright viewer is full mouse
+//! and keyboard control of a browser running inside a container that has
+//! passwordless sudo and, very often, the host's Docker socket bind-mounted. A
+//! bare loopback port is reachable by:
+//!
+//! * any other local user on a multi-user host, and
+//! * **any web page the user happens to have open**, via localhost port scanning
+//!   or DNS rebinding.
+//!
+//! So this module keeps the tunnel half of the auth bridge (a per-connection
+//! `socat` exec through the Docker API — see
+//! [`crate::auth_bridge::tunnel::tunnel_connection_with_prelude`]) and replaces
+//! the listener half with one that authenticates before a single byte reaches
+//! the container. There is therefore exactly **one** host-bound socket per
+//! session, and it is gated.
+//!
+//! ## The gate
+//!
+//! Gating happens on the first HTTP request head of every accepted TCP
+//! connection, before anything is forwarded. To get a connection through you
+//! must satisfy all of:
+//!
+//! 1. `Host` is `127.0.0.1:<port>` or `localhost:<port>` — this is the
+//!    anti-DNS-rebinding check. A page on `evil.com` that rebinds its name to
+//!    127.0.0.1 still sends `Host: evil.com`.
+//! 2. Either
+//!    * the request carries the session token (in `?token=`, in a `Cookie`, or
+//!      in the query of a same-origin `Referer`), **or**
+//!    * `Origin` / `Referer` is exactly this proxy's own origin — i.e. the
+//!      request was issued by a document that we already served, which itself
+//!      had to present the token. This is what lets the viewer's own
+//!      sub-resource and WebSocket requests through: a browser will not let a
+//!      hostile page forge either header, and requests that carry neither (a
+//!      cross-site `<script src>` or a top-level navigation) are rejected.
+//!
+//! Once the first head passes, the rest of the connection is spliced verbatim,
+//! so HTTP/1.1 keep-alive, the WebSocket upgrade and the CDP screencast frames
+//! all pass through untouched and protocol-agnostically. Riding an existing
+//! connection is not an escalation: opening one required the token.
+//!
+//! ## Port allocation and the CSP
+//!
+//! Host ports come from the small fixed range [`PROXY_PORTS`]. That is
+//! deliberate: `tauri.conf.json`'s `frame-src` has to name every origin the pane
+//! may embed, and CSP has no port wildcards short of `http://127.0.0.1:*`.
+//! Allocating from a bounded, known range keeps that directive an exact
+//! enumeration instead of "any localhost port".

+//! Shape mirrors `docker::stt`: an image that is either pulled from a registry

+//! named volume, and `get_* / ensure_*_running / stop_* / pull_* / build_*`.
+//!
+//! Two things differ from STT, both deliberate:
+//!
+//! * **The published host address is *detected*, not fixed.** STT is consumed
+//!   by the Tauri host process, so loopback is always enough. The gateway is
+//!   consumed by *project containers*, and how a container reaches the host
+//!   depends on the engine — so the bind address does too. See
+//!   [`GatewayBinding`]. It is never `0.0.0.0`: the config behind this port
+//!   holds a billed provider key, and Docker's published-port rules land in the
+//!   `DOCKER` iptables chain *ahead* of a host firewall, so a wildcard bind is
+//!   genuinely LAN-reachable even with `ufw` enabled.
+//! * **The rendered config is uploaded into the container over the Docker
+//!   API** rather than passed as env. It holds the provider API key, and both
+//!   env vars and labels are readable by anything on the host via
+//!   `docker inspect`.

+//! Contract types for **container base-image migration**.
+//!
+//! ## Why this exists
+//!
+//! A project's container is created from `triple-c-snapshot-<id>:latest`
+//! whenever that image exists, and every recreation re-commits it. Nothing ever
+//! moved a project back onto a *newer base image*: `container_needs_recreation`
+//! compared the container's actual image against the `triple-c.image` label that
+//! `create_container` wrote from the very image it created from — a tautology
+//! that could never fire. So a project stayed pinned to its own snapshot
+//! lineage forever and never picked up base-image fixes (a new `socat`, a new
+//! `/usr/local/bin` shim, security updates). The only escape was Reset, which
+//! deletes both named volumes and takes the login, the skills and every session
+//! transcript with it.
+//!
+//! Migration is the non-destructive alternative: recreate the container from the
+//! current base, then replay onto it the small set of things the base does not
+//! carry, and leave the volumes strictly alone.
+//!
+//! ## What actually needs replaying
+//!
+//! `/home/claude` is the named volume `triple-c-home-<id>`, with
+//! `/home/claude/.claude` nested inside it. The image's own `/home/claude` is
+//! **seed-only** — once the volume is mounted the image's copy is masked
+//! permanently. So Claude Code itself (it installs to `~/.local/bin`), cargo,
+//! uv, ruff, the OAuth login, `~/.claude.json`, skills, transcripts, scheduler
+//! tasks and SSH keys all re-attach for free across an image swap.
+//!
+//! What is genuinely lost is confined to the container's writable layer:
+//! root-level `apt` installs, `npm -g` packages (npm's prefix is `/usr`),
+//! `/usr/local`, `/opt`, `/srv`, anything under `/workspace` that is not on a
+//! bind mount — and **`/var`**. The first four are what [`MigrationOptions`]
+//! can replay. `/var` is not, and that gap is deliberate rather than an
+//! oversight, so it is stated here rather than glossed over:
+//!
+//! Service state lives in `/var/lib/<service>` and `/var/www`. Replaying the
+//! apt delta reinstalls `postgresql` onto the new base and hands back an
+//! **empty** cluster; the old one is gone with the writable layer. The
+//! ordinary recreate path does not have this problem, because it creates from
+//! the project's own snapshot and `/var` rides along — so a silent migration
+//! would be *more* destructive than the thing it is sold as a safer
+//! alternative to.
+//!
+//! Copying a live database's files out with `tar` and unpacking them onto a
+//! different base's version of the same package is not a fix; it is a
+//! corruption risk wearing a fix's clothes. So the answer is disclosure:
+//! [`crate::docker::migration::unpreserved_data`] finds the data-bearing
+//! subtrees under `/var` that the base does not ship, and
+//! [`ContainerStaleness::unpreserved_data`] carries them into the pre-flight,
+//! where the user is told to back them up before anything is touched.
+//!
+//! ## Serde
+//!
+//! Plain snake_case, matching every other IPC struct in this crate
+//! (`ContainerInfo`, `ClaudeSession`, …) and `app/src/lib/types.ts`.
