The observability validator checked for markdown headings (## Observability / Diagnostics,
## Observability Impact) that the DB-backed renderer never produces, causing false-positive
warnings on every dispatch. Removed entirely — the DB schema enforces structure at write time.
The worktree health check blocked execution in directories without recognized project files
(package.json, Cargo.toml, etc.), preventing greenfield projects from scaffolding. Downgraded
to a warning — .git check remains as the hard gate.
