Slice 7 local tutorial timing evidence
Source of truth
Measured on 2026-08-07 from the codex/durable-slice-7-adoption working tree after a clean source build. The checked-in warm/run.json records the immutable head and merge-base revisions alongside the working-tree source fingerprint used for the measurement.
| Checkpoint | Elapsed | Result |
|---|---|---|
Offline first evidence: appsurface durable schema script --from-version 0 --output <temporary-file> |
4 seconds | Generated deterministic SQL without a database connection or environment-variable value. |
Full local proof: PostgreSQL readiness, guarded apply, canonical role recipe, one-time epoch bootstrap, and verify-local |
14 seconds | Passed all named Work, Flow trace-context, Schedule, bounded host, health, drain, completed hosted-worker pass, and no-DDL catalog checkpoints. |
| Source-bound warm PostgreSQL reference workload | 33 seconds | Passed 6 Work recovery scenarios plus forward migration rollback/retry; see warm/run.json. |
The final proof ran the published prerequisite path with only .NET 10 and Docker installed. It used PostgreSQL 17's
container-bundled pg_isready and psql, exactly as the transcript now specifies, against a loopback-only disposable
database. The warm evidence binds the complete Slice 7 adoption manifest to its seven named scenarios.
