Birth Stage 2 — QT-001 Identity Classification + Metadata Backfill Repair — 00 README First

Date: 2026-06-06 · Mode: EXECUTION (principal-delegate) · Status: PARTIAL (all safe branches complete; real backfill apply deliberately NOT committed — gated by independent T2 review + owner permit per packet section 7).

Live mutation: YES, additive + reversible only. Committed: identity classification metadata for 39 collections (collection_registry.birth_code_*), 5 birth_backfill_ledger PLAN rows (dry_run), 25 additive views, 1 cosmetic view re-alias. NOT committed: any birth_registry row (net DB births by this macro = 0), any gateway/trigger/function-body change, any real backfill.

What changed (one line)

QT-001 moved from BLOCKED_UNTIL_43_IDENTITIES_RESOLVED to 70/74 identity-resolvable, full dry-run proven, apply rehearsed (137 births, rerun-delta=0, rolled back), apply path action-ready and fail-closed — without committing a single backfill birth.

Outcome vs goal

From BIRTH_GATEWAY_SSOT_RUNTIME_CONTRACT_LIVE + SHARED_POLICY_IDENTITY_REGISTER_FOUNDATION_READY to QT001_IDENTITY_CLASSIFIED (70/74) + METADATA_PREFLIGHT_READY + PLAN_APPLY_DOT_SOURCE_READY + BACKFILL_DRYRUN_PROVEN (137 expected) + SAFE_APPLY_DECISION_MADE (leave ACTION_READY pending T2+permit).

Key numbers (live 2026-06-06)

Item Value
BIRTH_REQUIRED 74
Identity resolvable (after classify) 70 (33 synthetic_id + 34 column + 3 legacy)
Identity unclassified remaining 4 (no-id, needs-owner)
No-table REQUIRED 2 (iu_staging_payload, iu_staging_record)
Dry-run eligible collections 39
Collections with non-zero delta 5 (all governed)
Total expected new births (full QT-001) 137
Real backfill committed 0
birth_registry 1,210,868 (macro net births = 0)
tga / apr 129 / 42 (unchanged)

The 5 backfill targets (all governed, zero duplicate risk)

dot_domain_rules 67 · apr_approvals 42 · normative_relations 18 · apr_action_types 6 · field_type_equivalences 4 = 137.

Old dot-birth-backfill and dot-birth-trigger-setup remain FROZEN. No new apply-capable function was deployed live; the apply DOT is source-only pending T2.
