By what warrant? — cell 4850007153
The attest verb answers "by what warrant do you say this?" for this Nanded locality cell: it RE-COMPUTES the SHA-256 of the source shard (never echoes the stored one) and walks the artefact's ancestry lineage. Fail-closed — it proves provenance or refuses, but never fabricates it.
Re-computed byte integrity
- Source shard
- derived/bharata_strata/sprint-6/mh36-unified-v1.8/admin_code=485/mh36_unified_v1_8.parquet
- SHA-256 recorded
- 0d704ad602791609ec17b2206fa5fa27a43230dc7bce7e35ba92dbb991a88804
- SHA-256 recomputed
- 0d704ad602791609ec17b2206fa5fa27a43230dc7bce7e35ba92dbb991a88804
- Verdict
- match — integrity verified (P5: recomputed, not echoed)

Version-dynamic shallow re-stamp (§17.4.4): columns byte-identical to the re-stamped version v1.8; only per_tier_pin_manifest + reemit_trigger + publish_utc are refreshed. All deep-emit ANCESTRY (network_features_promotion / tier_t genesis / ancestry chain) is preserved. Version + cube_seq are unchanged — a re-stamp is a freshness event, never a re-projection or a version bump.
