Adds an e2e/triage step to the TSIO summary job that answers the question a red run always raises: is this failure the PR's fault? It asks Test System IO for the past executions of exactly the tests that failed and applies history rules — infrastructure, owned by the PR's diff, broken on trunk, flaky on trunk, recurring on other PRs. Only what the rules cannot settle reaches a second judge, which may clear a failure only at high confidence and only while citing evidence a reviewer can open. Default mode is report-only: a sticky PR comment and nothing else. The five per-OS commit statuses are untouched, and the step is continue-on-error, so triage cannot change today's outcome. The context it would write under enforce is deliberately a new one rather than any of the required per-OS contexts, because one desktop run is a single TSIO group covering every OS and a verdict cannot yet be attributed to one leg.

prepare-matrix is skipped when instance_details is empty and can finish without an identity when preparation fails, but tsio-summary still runs because it is always(). The step then handed the action an empty string, which it JSON.parses before its first request, so it died inside continue-on-error and the PR got no comment at all.

tsio-summary checks out the branch under test and loads its helper files into github-script. Granting it pull-requests: write, as the previous commit did, would have let modified PR code use that job's GitHub client to mutate pull requests. Triage now runs as its own job that checks out nothing and whose only step is a SHA-pinned action. It orders after tsio-summary, which already polls until every leg has joined the TSIO group, so the group is settled by the time it runs. tsio-summary keeps exactly the permissions it had before.

The toolkit action now asks Test System IO for whole spec files instead of named test titles, because a reworded title used to lose all of a test's history. That changed the request it sends, so the pin has to move with it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The action could file a PR's own runs under "other PRs" when the composite identity carried gh_pr_number as a string, which is how jq builds it, and clear a failure using the PR's own history. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Adds main/master coverage. On main the rules invert: only an intermittent failure whose previous run passed clears, and a test that was failing in the previous main run too is a streak that stays red. Mode is unchanged, still report-only unless E2E_TRIAGE_MODE says otherwise. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Desktop's report names reduced to a different lane on PR runs than on master, so no trunk history was ever found. Also closes a path where a model could clear a regression without citing checkable evidence. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Review of the previous pin found three defects. Two siblings failing in one spec shared a history, so one could clear the other. A test whose identity could not be resolved was marked blocking and then sent to the model, which could clear it anyway. And the replay harness built an identity the engine no longer accepts, so calibration silently evaluated nothing.

The judge's answer now has to earn its trust. A confidence outside [0, 1] used to be clamped -- 7 became 1 and could clear a regression -- and is now rejected. The judge is pinned to claude-haiku-4-5-20251001 instead of the alias, and an answer from any other model is discarded. Temperature is set to 0 only for models that accept it. None of this changes this repo's configuration.

Each OS leg now writes its own e2e/<os> status from the triage verdict: success only when every failure is attributable to trunk or other PRs. Setting the E2E_TRIAGE_MODE variable to report-only turns it back off.

e2e-on-${{ matrix.runner }}, suppliestest-root: e2e/specs, and associates that verdict withe2e/${{ matrix.platform }}. A missing or unprovable report scope cannot clear a run.Triage now publishes a concise GitHub job summary and structured outputs;
post-pr-comment: "false"disables PR comments. The existingE2E_TRIAGE_MODEexpression keeps itsreport-onlyfallback. Required statuses change only in explicit enforce mode. Existing triggers, matrix, manual override behavior and error handling are unchanged.Validation: 63 shared-action tests pass; the changed workflow passes

Desktop builds and native E2E were not rerun locally for this action-pin update.Per-report and full-title history depend on deployed support from mattermost/mattermost-test-system-io#118. Keep report-only until real ownership evidence and updated calibration are reviewed. No rollout variable or Cursor repair trigger was changed.
