The general workflow guard caught an integration gap: it treated every composite step as a storage backend, so the two measurement steps violated its three-branch check. This was introduced by this PR, despite the focused reporting contract passing. The repair recognizes only the two exact nonblocking measurement commands, then applies the existing exhaustive backend conditions, pinned-action and read-only checks to the storage branches. Added regression mutations confirm an altered measurement command or overlapping provider condition still fails. The new regression fails before the guard change; all four focused tests and the actual read-only cache guard pass afterward. No cache behavior or assertion was removed. This push retains the failed predecessor run35531491815 as evidence. The new head requires its own hosted guard/contract results; no native test or provider benchmark was run locally. |

The macOS admission failure on0b33f33c4b3ef0d0b4d5ecfbb3e8672c51bd4e22 was before checkout: job106135214887 exhausted six Git fetch attempts across the checkout action and explicit retry, each unable to resolve github.com. The diagnostic curl also exited6. No source checkout, compiler or cache-receipt implementation ran in that job. This is a host/network failure; no source or provider settings change is justified by it. Separately, the new review finding about focused-workflow routing was valid. Commit599a656341c5c98e3f183870f5445e5c900360f2 adds the three inspected workflow/action inputs to both event filters. Regression66e910b5fe2e3fec838b4b4649e6a8a8da93b50d fails both events before the fix. All5 receipt tests, strict determinism lint and the actual read-only cache guard pass locally afterward. The thread is replied to and resolved. Auto-merge was disabled before this push. The necessary routing repair triggers fresh hosted validation naturally; no blind rerun, gate bypass or new provider route was introduced. Prior successful guard/web/contract runs remain predecessor evidence only. |

Validate ordered path-filter behavior.
issubset checks only positive membership. GitHub Actions evaluates paths patterns in order, so a later matching ! pattern excludes a path. A later !scripts/ci/cache_restore_receipt.py could therefore skip changes to that file while this assertion still passes. Evaluate patterns with ordered matching, or add a mutation test that inserts this negation and asserts failure.

The cache-restore composite exposes only an exact-hit flag, which cannot explain whether a restore used a prefix, failed, or selected a different action route on another runner. Add one structured
CMUX_CACHE_RESTOREreceipt and job-summary entry per restore, including requested backend, selected action route, runner, key/matched key, outcome and elapsed time.Keep the existing cache-hit output, selection conditions and backend default unchanged. Exact and prefix restores use the pinned actions' outputs. Failed/cancelled steps remain distinct; a successful action without a matched key reports
miss_or_unavailable, since suppressed backend errors cannot be distinguished from a miss. Missing/ambiguous evidence remains unknown. Both measurement steps are non-blocking, and reporting does not hide a failed restore. No URLs, credentials or cache paths are recorded.This complements #13268's optional artifact broker without changing its transport steps, #13260's checkout optimization, or the app-host payload/retention work. It changes no provider credentials, settings, restore order or cache writes.
Provider evidence matters for interpreting receipts: Blacksmith documents transparent cache interception on its Linux VM architecture and explicitly distinguishes ordinary artifact traffic; that is not proof of macOS interception. Warp's cache action supports exact/prefix semantics, while its artifact guide uses GitHub artifact actions. Therefore
github-cachemeans the selected action route, not a verified physical store. R2 custom-domain caching is a separate deployment choice; this patch does not enable it.Validation: five focused Python tests and the existing read-only cache guard pass, including 18 provider/outcome cases and execution of the actual composite clock/report shell with output-boundary fixtures. The composite-wiring test fails against the previous action and passes after the change. It checks default/output preservation, arbitrary key quoting, duration and summary emission; no provider network calls or native build were run. Mutation regressions confirm that altered measurement commands and overlapping cache routes still fail the exhaustive read-only guard. A path-filtered Linux workflow runs this contract.
git diff --checkpasses.No latency or dollar saving is claimed: the improvement is trustworthy cache-state evidence for future cohorts. Duration covers lookup, transfer and extraction, and hard runner termination may prevent a final receipt.
