The triage worker added the 'evaluate-now' label via GITHUB_TOKEN, but label events emitted by GITHUB_TOKEN do not start workflows (GitHub's recursion guard), so evaluation.yml's pull_request_target:[labeled] entry point never fired for the bot (repro: PR #745). workflow_dispatch and repository_dispatch are the only token-initiated events exempt from that guard.
The worker now dispatches evaluation.yml directly via 'gh workflow run' with a pr_number input, routed through the existing gate job so the path is identical to /evaluate. A dispatched run's head_sha is the default branch (not the PR head), so idempotency now matches the deterministic run name 'Evaluate PR #<n> @ <sha7>'. The 'evaluate-now' label remains a valid human entry point. Worker granted actions:write for 'gh workflow run'.
* PR triage workflows: orchestrator, worker, and evaluate-now label
Implements docs/design/pr-triage-workflows.md:
- pr-triage-batch.yml: hourly orchestrator that classifies open PRs
- pr-triage.yml + pr-triage-act.sh: per-PR worker (state recompute,
label reconciliation, eval-trigger, ping comments with cool-down)
- evaluation.yml: gate job now also handles pull_request_target [labeled]
with the evaluate-now label as a second entry point alongside /evaluate
* Add temporary push triggers for testing pr-triage workflows
* test: live-run pr-triage worker once
* test: re-run worker for cool-down check
* fix: age gate uses created_at and applies only before first ping
* Remove temporary test triggers and inline test marker
* Add pr-malicious-scan agent workflow; replace design doc with brief overview
- New: .github/workflows/pr-malicious-scan.agent.md + compiled .lock.yml.
Static diff scanner for external (non-trusted) PR contributors. Triggers
on pull_request_target [opened/synchronize/reopened] and workflow_dispatch.
Surfaces findings as code-scanning alerts plus a single maintainer-ping
comment per head SHA when high-severity / workflow-tamper / supply-chain
hits. Never executes PR head code.
- docs/design/pr-triage-workflows.md replaced with a brief overview + diagram.
The full implementation plan is kept locally as
docs/design/pr-triage-workflows-plan.md (gitignored).
- pr-triage-batch.yml's existing dispatch-scanner branch now resolves to
the new scanner; orchestrator unchanged.
* Fix markdownlint MD038 (pipe inside code span) in malicious-scan agent
