 This is the result of a deliberate "no TODOs in main" discipline — incomplete work either ships behind a clear interface or is captured in plan files (now wiped). The flip side: there's no in-code roadmap for "things known to need work". The list below substitutes for that, drawn from comments, deleted plan files, and observed bugs.

 2. **Wire the new reference docs into `go-ci.yml` or `security.yml` link-check** — broken markdown links would be the most likely doc-bitrot vector.
 3. **Add a `gh attestation verify` example to the README** — the binaries ship with build provenance but it's invisible to consumers.
