# Evidence Bundle Tier Labeler

`POST /v1/tools/assemble_ocg_evidence_bundle`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/assemble_ocg_evidence_bundle`
- Auth: none declared

Assembles a shareable evidence bundle around an artifact and stamps the SPEC.md §SIDECAR.1 tiered label it qualifies for: OCG-Verify (envelope well-formed, execution_hash recomputes), OCG-Execute (additionally §21 chain-execution and §22 mandate gates hold), OCG-Prove (additionally a §18 compute-integrity proof verifies). Tiers are cumulative -- any gate false at a level makes every level above it unavailable. The label adds no new gate and mints no new trust claim: it re-expresses existing gate-pass results the caller declares for the referenced artifact, and this node never re-runs those gates itself. When the caller supplies collected section-27.2 human-accountability records, they consume/emit as a section-27.6 evidence bundle keyed to the same artifact hash, so the tier label and the accountability trail ride one diffable object. Zero network, zero PII.
