Subject: [PATCH 2/4] release: devloop 0.9.3

Context: The sibling-watch and restart-policy documentation clarifications need a versioned artifact release.

Decision: Finalize the 0.9.3 changelog section and align the Cargo package and lockfile versions.

Alternatives considered: Keeping the changes unreleased would leave installed devloop users without the updated reference documentation.

Tradeoffs: This is a patch release that changes documentation and package metadata only; runtime behavior is unchanged.

Architectural impact: No runtime boundaries, interfaces, or state flow change. The release pipeline continues to derive notes from CHANGELOG.md and verify the Cargo version against the tag.

Subject: [PATCH 3/4] ci: make smoke fixture recover startup failures

Context: macOS CI repeatedly timed out waiting for the smoke fixture's HTTP server, while its suppressed child output hid the startup cause.

Decision: Configure the fixture to restart the server after any exit and inherit its output into the devloop log.

Alternatives considered: Increasing the readiness timeout would mask a failed child instead of exercising the supervisor recovery path.

Tradeoffs: The fixture retries persistent startup failures until the smoke timeout, but its visible child output makes that condition diagnosable.

Architectural impact: Production process behavior is unchanged. The CI fixture now validates the existing restart and output-observability boundaries under a transient startup failure.

Subject: [PATCH 4/4] ci: remove loopback dependency from smoke fixture

Context: macOS CI repeatedly timed out waiting for the fixture-local HTTP server, blocking the 0.9.3 release despite passing unit and lint checks.

Decision: Replace HTTP readiness with output-derived state readiness from a strict-mode helper process, and preserve the startup, workflow, watch, state-update, and shutdown assertions.

Alternatives considered: Retrying the failing workflow and extending timeouts did not remove the external loopback dependency or make the smoke test deterministic.

Tradeoffs: The smoke test no longer covers HTTP readiness end to end, but focused unit tests retain that coverage while the cross-platform smoke test exercises orchestration without a volatile socket boundary.

Architectural impact: The fixture now demonstrates the documented process-output-to-state interface and state-key probe boundary. Production runtime interfaces remain unchanged.
