 - [x] Preserve the minimal launch-env and ACP-start runtime-assets boundary from PR #1561; add contract tests that fail if runtime assets or user secrets move into the image/launch config.
 - [x] Add unit/contract/deployment tests for phase timing invariants, baked binary presence/versioning, workflow ordering, rollback behavior, and no-secret image inputs.

+## Post-Rebase Validation (2026-07-12)

+- Rebased linearly onto `ad7044fde` (PR #1562); the rebased tree matches the previously reviewed merge resolution exactly.
+- `pnpm lint`, `pnpm typecheck`, `pnpm test`, and `pnpm build` passed. The full test run included 404 API files / 5,918 tests and 217 web files / 2,668 tests.
+- Targeted cold-start tests passed: 16 API contract/timing/bootstrap tests and 7 deploy-workflow tests.
+- `/usr/local/go/bin/go test ./...` passed for the full vm-agent module under Go 1.25.0.
+- `make -C packages/vm-agent prepare-container VERSION=local-rebase-3bf1a466d` generated the Linux/amd64 binary and version metadata successfully.
+- The actual `Dockerfile.vm-agent-container` built locally. A standalone probe using the normal entrypoint emitted `vm_agent_container_bootstrap_ready` in 3 ms with the baked version/sha256, remained running, and returned `{"status":"healthy"}` from `/health`; the probe container was removed.
