A green self-check still had a boundary

[measured] Signal health (self) run 32 completed successfully with 2 jobs and 11 successful steps, but the receipt covers only one scheduled chain.

[measured] Public Signal health (self) run 32 on head SHA c8d73ce0 completed with success on 11 September 2026 at 08:57 UTC. The receipt is a public CI run, not a claim about the whole repository.

The Jobs API separates the run into publish-the-numbers with 6 steps and verdict-on-ci / measure with 5 steps. Every listed step concluded success, including the measurement and completion steps.

A green receipt is evidence about the chain it names: SHA → event → workflow → job → step → conclusion.

What this does not prove

The practical engineering value is to keep the receipt at the same granularity as the claim. Inspect the jobs and steps first, then verify the produced values and their sources separately.
