Task 6 — Version, aggregate doctor, and build-aware start

Status: complete.

Implemented the host-side tht version, aggregate tht doctor [--json], and tht start [--build] contracts.

• version is descriptor-free and reports semantic version, commit, build time, OS, and architecture.
• doctor emits typed, redacted checks for descriptor state, Docker/Compose, rendered volumes, file permissions, service health, workspace registry, the container-local workflow doctor, and Pi doctor. Its JSON mode writes exactly one JSON document to stdout.
• The Python workflow doctor is invoked only as docker compose exec -T core tht doctor --json after core is running.
• start uses the shared lifecycle service: default up → health; --build is build → up → health.
• setup now reuses the shared lifecycle and aggregate diagnostics rather than keeping parallel health/volume implementations.

Verification performed without live Docker/container commands:

cd tools/tht
go test ./internal/version ./internal/doctor ./internal/service ./cmd/tht \
  -run 'TestVersion|TestDoctor|TestStart|TestCurrent|TestRun' -count=1
go test ./internal/setup -count=1 -run 'TestRun' -v
go test ./... -count=1
git diff --check

All completed successfully. The intentionally fake runner coverage includes unavailable Docker, stopped/running core, workflow failure redaction, pristine JSON output, and start ordering.

Concerns: no live Docker validation or host installation was run, by explicit task constraint.

Fix round 1

Completed the independent-review follow-up without live Docker operations.

• workspace-registry now executes a container-local, read-only Node validation of /data/workspace-registry/state/active.json and every declared snapshot descriptor. It no longer passes merely because Compose declares a volume.
• Host file permissions are checked before Docker/Compose availability and therefore remain visible as failures when Docker is unavailable.
• Separate typed, bounded HTTP probes verify core (curl --max-time 5) and frontend (wget -T 5) reachability, independently of Compose health. The probe is injectable in tests.
• The successful report tests assert the stable full checklist: descriptor, files, docker, compose, configuration, services, core-http, frontend-http, workspace-registry, workflow, pi.

Additional verification:

cd tools/tht
go test ./internal/doctor -run 'TestRun(ChecksUnsafeFilesEvenWhenDockerIsUnavailable|FailsAnInvalidContainerLocalRegistryState|ReportsEachHTTPReachabilityProbeFailure|UsesOnlyContainerLocalWorkflowAndPiDiagnosticsWhenCoreRuns)' -count=1 -v
go test ./internal/doctor ./internal/setup ./internal/service ./cmd/tht -count=1
go test ./... -count=1
git diff --check

All passed with fake runners/probes only. No live container, HTTP endpoint, or host installation was touched.
