fix(ci): keep main planning exhaustive

[ndizazzo]

Summary

• make main/manual-full planning ignore partial diff-scoped affected-crate input
• preserve the exhaustive workspace Rust matrix required by trusted main builds
• scope the PR runner-policy scan to the five validation entrypoints, excluding metadata-only cleanup/assignment workflows
• add regressions for both integration failures observed after ci: split planning and platform workflow graphs #1282

Validation

• targeted planner/runner-contract tests: 35 passed
• just ci-validate: 430 passed, 7 skipped; actionlint and all consistency checks passed

Incident

The first direct five-workflow main run after #1282 passed a diff-scoped affected_crates list into the main profile. The planner honored that partial list before applying the main profile policy, then correctly rejected its own non-exhaustive Rust-test matrix. The merged base also broadened the runner-contract glob to metadata-only pull_request_target workflows, contradicting the documented five-entrypoint validation boundary. This change makes the exhaustive profile authoritative and keeps the runner scan aligned with that boundary.

Summary by CodeRabbit

• Bug Fixes

  • Full CI validation now runs for main and manual full-check profiles, even when only a partial set of changed components is provided.
  • CI workflow checks now target the intended pull request validation workflows explicitly, improving scan reliability.

• Tests

  • Added coverage for complete affected-component detection, Rust test execution, and precise workflow selection in full CI plans.

📝 Walkthrough

Walkthrough

The CI planner now selects all workspace crates for main and manual-full plans. Other profiles retain supplied crate lists before fallback discovery. The runner contract scans five explicit PR workflows. Tests cover both changes.

Changes

CI validation

Layer / File(s)	Summary
Profile-aware crate selection and regression coverage scripts/plan-ci.py, scripts/tests/test_plan_ci.py	main and manual-full select all workspace crates. Other profiles use supplied crates before fallback discovery. The test verifies crate expansion and Rust test scheduling.
Explicit PR workflow scanning and regression coverage .github/workflows/ci-runner-contract-slice.yml, scripts/tests/test_reusable_workflow_runner_trust.py	The runner contract scans five named PR validation workflows. The test verifies inclusion of those workflows and exclusion of wildcard, auto-assignment, and cleanup workflows.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🔵 Low · up to 96abc

The PR makes main and manual-full planning exhaustive and narrows runner-policy validation to the five intended entrypoints; merge is reasonable with owner awareness that the manual-full branch still needs explicit regression confirmation.
