Evidence Bundle Tier Labeler

Assembles a shareable evidence bundle around an artifact and stamps the tiered label it qualifies for — OCG-Verify, OCG-Execute, or OCG-Prove — computed purely from which §15 gates you declare passed for that artifact.

Tiered Label No New Gate Re-expresses Existing Proofs

🔒 All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data — use synthetic or anonymised inputs only.

⚠ This node does not re-run §1/§4/§18/§21/§22 gates itself. The five gate checkboxes below are your own declaration of prior gate outcomes for the referenced artifact — not independently re-verified here.

The tiered label adds no new gate and mints no new trust claim (SPEC.md §SIDECAR.1) — it re-expresses existing gate-pass results as a single naming, atop the gate suite that already exists.
