TestGrid accepts a required digest-pinned bundle reference, verifies signer policy, provenance, and source classification, then publishes after cloud authentication. Contributor and user documentation describe the updated publication and classification behavior.

- docs/contributor/evidence-ingest.md, evidence-dashboard-publish.md: rename trigger-dashboard -> trigger-publishes to match the renamed job, and document the new TestGrid dispatch alongside the dashboard refresh. - testgrid-publish.yml: remove the vestigial skip=false output and the now-always-true "if: steps.bundle.outputs.skip != 'true'" guards on five downstream steps. The removed pointer-discovery logic was the only code path that ever set skip=true; Resolve bundle ref now either succeeds or exits 1, so the guards were dead weight left over from the old workflow_run/pointer.yaml flow. Found via cross-review of PR #2330 (Claude Code + Codex + CodeRabbit, consensus 2-3/3).

The dispatch fix is sound. The old listener watched top-level UAT Run, and workflow_run events are suppressed for runs the nightly controller dispatches with GITHUB_TOKEN, so it never fired; workflow_dispatch is explicitly exempt from that suppression and is the right escape. Separately, evidence-ingest reached as a nested workflow_call emits no top-level run of its own, which is why the dispatch has to originate there rather than from a listener.
Verified: --ref main keeps release/* bundles running main's copy of the file, so the WIF workflow_ref principalSet holds; the verifier flags all exist in tools/evidence-project/main.go:70-81; the identity regexp is evidence-ingest.yaml:81's pin narrowed to main|release/*; yq is genuinely unused after the setup-build-tools removal; actions: write is present in all four UAT callers and all four uat-run call sites. Azure run 32458074857 confirms a real bundle ref, signer identity, and branch that satisfy the proposed gates — it does not exercise this PR's TestGrid workflow or the WIF path end to end, so the new path is still unproven in practice.
One blocker, not in the code: commit 8c87f9b has no Signed-off-by trailer. The other two commits on the branch do, and all three are cryptographically verified. Nothing in CI catches this — there is no DCO check among the 40 checks here — so it needs a manual fix. The same commit's body names the reviewing agents, which is against the no-attribution policy. The squash configuration limits how far that travels, but the branch still violates policy today. The branch is 3 ahead and 4 behind main, so the required rebase can carry both corrections.
Beyond that: one scope decision on community bundles and one comment correction, inline.

Approving. Both review comments are addressed in the current head.
Classification is now derived from the verified Fulcio certificate rather than caller input: first-party is re-pinned to the NVIDIA UAT main/release/* identity before it earns uat, community/partner map to community, and an unrecognized class fails closed. The community path is preserved through a checked-in pointer whose claimed issuer and identity are escaped into an exact-match policy and cross-checked against the certificate, so a pointer cannot widen its own trust. docs/user/testgrid.md:75 no longer contradicts the workflow.
The concurrency comment now attributes durable overwrite rejection to the publish SA's create-only IAM grant and states that this does not make a partially completed upload safely retryable. No publisher-level idempotency is claimed.
One non-blocking follow-up: docs/user/testgrid.md explains what source_class means but never tells a community submitter how to get published — the backfill mechanics live only in docs/contributor/evidence-ingest.md. Since removing the input closed the previously obvious manual path, surfacing that pointer in the user-facing doc would close the loop. Fine as a separate change.

Summary
Dispatch TestGrid publishing directly from the verified evidence-ingest stage using the digest-pinned bundle reference, matching the existing dashboard refresh path. Replace the unreliable
workflow_runlistener and derive each TestGrid source class from verified signer policy rather than caller input.Motivation / Context
Nightly UAT runs are dispatched by
github-actions[bot]withGITHUB_TOKEN. GitHub suppresses the downstreamworkflow_runchain, so those runs generated and ingested evidence successfully but never launched TestGrid Publish. Explicitworkflow_dispatchis a supported recursion exception and is already used by evidence ingest to refresh the static evidence dashboard.Fixes: N/A

Rollout notes: The first post-merge evidence ingest should create a top-level TestGrid Publish run. The new workflow/WIF path remains unproven end to end until that run; existing immutable bundle refs can be manually backfilled afterward.
