- * Pulls a team-shared TIA baseline on the first `--tia` run so new

- *
- * Storage: **workflow artifacts**, not releases. A dedicated CI workflow
- * (conventionally `.github/workflows/tia-baseline.yml`) runs the full
- * suite under `--tia` and uploads the `.temp/tia/` directory as a named
- * artifact (`pest-tia-baseline`) containing `graph.json` +
- * `coverage.bin`. On dev
- * machines, this class finds the latest successful run of that workflow
- * and downloads the artifact via `gh`.
- *
- * Why artifacts, not releases:
- *   - No tag is created → no `push` event cascade into CI workflows.
- *   - No release event → no deploy workflows tied to `release:published`.
- *   - Retention is run-scoped and tunable (1-90 days) instead of clobbering
- *     a single floating tag.
- *   - Publishing is strictly CI-only: artifacts can't be produced from a
- *     developer's laptop. This enforces the "CI is the authoritative
- *     publisher" policy that local-publish paths would otherwise erode.
- *
- * Fingerprint validation happens back in `Tia::handleParent` after the
- * blobs are written: a mismatched environment (different PHP version,
- * composer.lock, etc.) discards the pulled baseline and falls through to
- * the regular record path.
