fix: resolve merge conflict — integrate agent's story-aware ContainerRunner

Agent added: Store on ContainerRunner (direct story/project lookup), --reference
clone for speed, explicit story branch push, checkStoryCompletion → SHIPPABLE.
My additions: BranchName on Task as fallback when Store is nil, tests updated
to match checkout-after-clone approach.

 ## Current Task Goal
-ADR-007 implementation: Epic→Story→Task→Subtask hierarchy, project registry, Doot integration
+Move Claudomator UI auth into Doot: replace Apache proxy rules with a Doot-side
+reverse proxy, gating `/claudomator/*` behind Doot's session auth.

+## Status: PLAN — awaiting user confirmation

-## Completed Items
-
-| Step | Description | Test / Verification |
-|------|-------------|---------------------|
-| Phase 1 | Doot dead code removal: Bug struct, BugToAtom, bug store methods, bug handlers, bug routes, bugs.html template, TypeNote, AddMealToPlanner stub | `go test ./...` in /workspace/doot — all pass (2 pre-existing failures unrelated) |
-| Phase 2 | Claudomator project registry: `task.Project` type, storage CRUD + UpsertProject, seed.go, API endpoints (GET/POST /api/projects, GET/PUT /api/projects/{id}), legacy AgentConfig.ProjectDir/RepositoryURL/SkipPlanning fields removed, container.go fallback removed, fallbackGitInit removed, processResult changestats extraction removed (pool-side only) | `TestCreateProject`, `TestListProjects`, `TestUpdateProject`, `TestProjects_CRUD` — all pass |
+## Plan: Claudomator UI behind Doot auth
+
+### Architecture
+```
+Browser → Apache (SSL) → Doot :38080 → [session auth] → Claudomator :8484
+```
+Apache currently proxies `/claudomator/*` directly to :8484 with no auth.
+Goal: move the proxy into Doot so session middleware gates it.
+Two processes, two systemd units — unchanged.
+Claudomator base-path already hardcoded to `/claudomator` in web/index.html.
+
+### Step 1 — Doot: add `ClaudomatorURL` config
+- `internal/config/config.go` — add `ClaudomatorURL string` (env: `CLAUDOMATOR_URL`, default: `http://127.0.0.1:8484`)
+- Tests: default + override
+
+### Step 2 — Doot: HTTP + WebSocket reverse proxy handler
+- New file: `internal/handlers/claudomator_proxy.go`
+- `httputil.ReverseProxy` for normal requests; WS connection hijacker for upgrades
+- Director strips `/claudomator` prefix from both `URL.Path` AND `URL.RawPath` (handles encoded chars in task names/IDs)
+- Do NOT set `ReadDeadline`/`WriteDeadline` on hijacked WS connections (kills long-lived task monitoring)
+- Preserve `Service-Worker-Allowed` response header so SW scopes correctly under `/claudomator`
+- Tests: HTTP forward, prefix strip, WS tunnel
+
+### Step 3 — Doot: restructure CSRF middleware, mount proxy
+- `cmd/dashboard/main.go`: move CSRF out of global middleware into a route group
+- `/claudomator` → redirect 301 to `/claudomator/` (trailing slash; prevents asset fetch breakage)
+- `/claudomator/api/webhooks/github` → exempt from `RequireAuth` (GitHub POSTs have no session; endpoint does its own HMAC validation)
+- `/claudomator/*` route: `RequireAuth` only (no CSRF — SPA doesn't send Doot's CSRF token)
+- All other routes: wrapped in CSRF group (behavior unchanged)
+
+### Step 4 — Apache: remove Claudomator proxy rules
+- Remove 4 lines from `/etc/apache2/sites-enabled/doot.terst.org-le-ssl.conf`
+- `apache2ctl configtest && apache2ctl graceful`
+
+### Step 5 — Smoke tests
+- Unauthenticated `/claudomator/` → 302 to `/login`
+- `/claudomator` (no slash) → 301 to `/claudomator/`
+- Authenticated: UI loads, task CRUD works, WS live updates, log streaming
+- GitHub webhook POST to `/claudomator/api/webhooks/github` → not redirected to login
+
+### Risks
+- CSRF restructure: verify all existing Doot routes still pass their tests after moving CSRF to a group
+- SecurityHeaders CSP already allows `wss: ws:` — no change needed
+- Claudomator :8484 remains accessible on localhost without auth (acceptable for now)
+- Future: `/claudomator/api/*` technically CSRF-vulnerable from other origins; mitigate later by injecting `XSRF-TOKEN` cookie
