Summary

Adds PRD 0016, the heaviest of the three remediation engines in the stuck-agent recovery flow (overview in PRD 0012, foundation in PRD 0013). Wires the capability block path: rebuild orchestrator, state-preservation helper, and the end-to-end capability-block handler. On operator approval the orchestrator tears down the bottle, builds from the proposed Dockerfile, and starts a replacement bottle on the same branch via the state-preservation helper.

State-preservation is bundled into this PRD rather than carved out separately — capability-block is its only consumer today, and pre-extracting the abstraction would be premature.

Depends on PRD 0013 landing first.

Adds PRD 0016, the heaviest of the three remediation engines in the
stuck-agent recovery flow (overview in PRD 0012, foundation in PRD
0013). Wires the capability block path: rebuild orchestrator,
state-preservation helper, capability-block end-to-end. On approval
the orchestrator tears down the bottle, builds from the new
Dockerfile, and starts a replacement on the same branch via
state-preservation.

Phase 1 of PRD 0016. Lays the per-bottle state plumbing that
capability-block remediation will write into:

- claude_bottle/backend/docker/bottle_state.py: bottle_state_dir,
  per_bottle_dockerfile (read), write_per_bottle_dockerfile,
  per_bottle_image_tag (unique per slug), transcript_snapshot_dir.
  Stores under ~/.claude-bottle/state/<slug>/.
- prepare.py: when a per-bottle Dockerfile exists, use
  per_bottle_image_tag(slug) as the base image and pass the
  per-bottle Dockerfile path through DockerBottlePlan.dockerfile_path.
  --cwd still layers a derived image on top.
- launch.py: passes plan.dockerfile_path to build_image so the
  per-bottle Dockerfile is what docker build reads.
- DockerBottlePlan gains dockerfile_path field; print() surfaces it
  in the preflight summary so the operator can see at-a-glance that
  this bottle is running on a rebuilt image.

Phase 2 will write to write_per_bottle_dockerfile (capability-block
approval); Phase 3 wires it into the dashboard.

Phase 2 of PRD 0016. New module
claude_bottle/backend/docker/capability_apply.py:

- apply_capability_change(slug, new_dockerfile): snapshot transcript
  → push working tree → write per-bottle Dockerfile → teardown.
  Returns (before, after) for the dashboard's audit/diff render.
- fetch_current_dockerfile(slug): per-bottle Dockerfile if set,
  else the repo's Dockerfile.
- Internal helpers _snapshot_transcript, _push_working_tree are
  best-effort (log + return on failure); _teardown_bottle is
  idempotent (force-rm + network rm silently ignore missing names).

Fire-and-forget from the agent's perspective: by the time the
dashboard writes the response file the supervise sidecar is already
gone (it was torn down), so the agent's tool call connection drops
without receiving the response. The replacement agent (next manual
`cli.py start <agent>`) sees the new per-bottle Dockerfile and the
transcript snapshot for resume. v1 does not auto-relaunch.

Tests cover sequencing (snapshot → push → teardown order), the
per-bottle vs repo Dockerfile fallback chain, empty-input rejection,
and the per-bottle-Dockerfile write. The docker exec / cp / rm
plumbing is covered by the Phase 4 integration test.

Phase 3 of PRD 0016. dashboard.approve() now dispatches to
apply_capability_change when the proposal is a capability-block:

  cred-proxy-block → apply_routes_change
  pipelock-block   → apply_allowlist_change
  capability-block → apply_capability_change   (new in PRD 0016)

CapabilityApplyError joins the ApplyError tuple, so the TUI's key
handlers catch it the same way and surface failures in the status
line.

After a successful capability-block apply, dashboard archives the
proposal+response itself — the supervise sidecar was torn down by
apply_capability_change and can't archive its own queue file.
Without this, dashboard.discover_pending would keep surfacing the
resolved proposal forever.

No audit log for capability-block per PRD 0013 — its record lives
in the per-bottle Dockerfile state + transcript snapshot.

Tests stub apply_capability_change at the dashboard module level,
add TestCapabilityApplyWiring (call wiring, failure-keeps-pending,
no-audit invariant, archive-after-apply), and update TestApproveReject
to stub the capability path too so it stays docker-independent.

Phase 4 of PRD 0016. End-to-end test against real Docker:

- Stages a fake bottle: alpine:latest container named
  claude-bottle-<slug> with a marker file at
  /home/node/.claude/sessions.json, plus a fake supervise sidecar.
- Calls apply_capability_change with a new Dockerfile.
- Verifies: per-bottle Dockerfile written, agent + sidecars
  removed, networks removed, transcript snapshot dir on host
  contains the marker file (proving docker cp transferred bytes).
- Subsequent-apply test proves the per-bottle Dockerfile state
  persists across rebuilds (before-diff uses the prior override,
  not the repo Dockerfile).
- Teardown-idempotent test: apply against a never-started bottle
  doesn't raise.

docker exec / cp / rm / network rm work fine across the docker
socket boundary, so this runs in DinD too — no act_runner skip
needed.

fix(bottle): identity-key all per-bottle resources by (agent, cwd)
test / unit (pull_request) Successful in 16s
test / integration (pull_request) Successful in 1m30s
e996f72532
The single point that computed `slug = slugify(agent_name)` in
prepare.py is now `slug = bottle_identity(agent_name, cwd)`. With
--cwd the identity has a sha256(resolved-cwd)[:12] suffix, so the
same agent against different projects gets distinct container
names, network names, queue dir, audit log paths, and per-bottle
state (Dockerfile + transcript). Without --cwd the identity is
just slugify(agent_name), unchanged from before — no-cwd bottles
look the same as today.

The downstream `slug` field on DockerBottlePlan keeps its name —
every module already threads it under "slug" and the value flowing
through is now the bottle's full identity. A comment in prepare.py
flags the change.

Fixes the bug surfaced in PR #22 review: running the same agent
against project-A's cwd then project-B's would silently share
project-A's per-bottle Dockerfile + transcript snapshot, container
name (forcing serialized runs), and queue/audit history.

feat(bottle): random-suffix identity + cli.py resume <identity>
test / unit (pull_request) Successful in 18s
test / integration (pull_request) Successful in 1m30s
4032e04a9c
Replaces the cwd-hash identity with a random 5-char base36 suffix
per launch, so two simultaneous `start <agent>` invocations against
the same cwd no longer collide on container names. Each launch is
its own bottle.

State carries metadata: every prepare step writes
~/.claude-bottle/state/<identity>/metadata.json with the
(agent_name, cwd, copy_cwd, started_at) the bottle was launched
with. The new `cli.py resume <identity>` reads this metadata and
re-launches a bottle pinned to the same identity — picking up the
per-bottle Dockerfile (from a prior capability-block apply) and
the transcript snapshot under the same state dir.

- bottle_state.py: bottle_identity(agent_name) drops the cwd param
  and gains a random suffix; BottleMetadata dataclass +
  read/write/metadata_path helpers.
- BottleSpec gains an optional identity field — resume sets it to
  pin the identity; start leaves it empty so prepare mints fresh.
- prepare.py: writes metadata at launch time; uses spec.identity if
  provided (resume) else bottle_identity(agent_name) (fresh start).
- start.py: extracted _launch_bottle from cmd_start so resume can
  share the launch core; prints `./cli.py resume <identity>` hint
  at session end.
- cli/resume.py (new): reads metadata, reconstructs BottleSpec
  with the recorded identity + cwd, delegates to _launch_bottle.
  Errors clearly when no state exists for the given identity.
- cli/__init__.py: registers `resume` in COMMANDS + usage.
- dashboard.py: capability-block approval status line now appends
  the `resume <identity>` hint so the operator can copy-paste the
  rebuild command without leaving the TUI.

Closes the rebuild loop in PRD 0016: agent calls capability-block →
operator approves → bottle torn down with state preserved → status
line shows resume command → operator runs it → replacement bottle
boots with the new Dockerfile and prior transcript.
