The Fresh-Box Readiness Check and Release Path

This sprint was asked to hold the hardest abstraction in the preflight milestone: one inventory of external tools, with local detection, platform hints, and injectable results for tests. It was a good isolated assignment because it did not need the finished command or startup UI; it only had to expose the facts they would read. Its green boundary mattered because every later preflight sprint depended on this module being the only source of truth.

With the inventory in place, this sprint could be only about command wiring and report presentation. The brief kept it narrow: recognize `doctor` as a bare verb, run outside a repository, enumerate all registered harnesses, print grouped results, and return a scriptable status. It landed without recorded repair, showing that the previous inventory cut had left a direct user-facing surface to attach.

This sprint deliberately had less design freedom than the inventory work. It had to preserve existing startup failure behavior while replacing scattered probes with the shared inventory and adding the early git check. That made the boundary mostly integration: a fresh agent could focus on the startup path, the selected harness set, and message behavior. The gates stayed green, so no hidden divergence between doctor and startup surfaced during the run.

This was a thin documentation sprint placed after the behavior existed. Its job was not to invent more readiness logic, only to add the command table entry, dependency-install notes, and cross-references to authentication and sandbox setup. Because it mirrored code already built and tested, it stayed within a small context and completed without recorded repair.

The release work started by removing the blocker that would make every later distribution task fail in a plain checkout. This sprint had a concrete boundary: copy the terminal menu crate into `vendor/`, repoint the path dependency, record provenance, and prove the repository no longer needed the sibling source tree. It stayed green, giving later release sprints a self-contained build base.

This small sprint sat between vendoring and release packaging because the release smoke test needed a predictable version line. Its scope was narrow enough for one agent: recognize the top-level flags early, print the crate version, and avoid consuming ordinary plan text by mistake. It completed cleanly, leaving the pipeline sprint with a simple binary launch check to call.

This was the release milestone's broadest sprint, but the earlier cuts reduced what it had to assume. It inherited a self-contained checkout and a version command, then focused on well-formed release configuration, workflow structure, artifact contents, signing behavior, and a smoke check rather than proving hosted runner behavior locally. The gate stayed green, which matched the brief's limit: local verification could prove configuration shape, not actual remote notarization.

The brief made this sprint secondary to the release matrix and gave it an honest fallback: wire the nag if it fit, or leave a concrete handoff. The worker landed the offline comparison and update-check seam while keeping the network side quiet and documented. That was a narrow, testable compromise, and the sprint needed no recorded repair.

This final sprint was documentation-only and depended on the actual release shape produced before it. Its assignment was to describe the download path, connect installation back to `gantry doctor`, and state the Windows scope decision. With code already settled, the worker only had to align README and project docs with the artifacts the milestone had produced, and it completed without recorded stress.
