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.
