Verdict

Agent PASS. Opus review is correct on evidence. Birth inventory is PARTIAL because of trigger coverage gap, not because the existing birth engine is broken.

Mainline remains:

P3D_BIRTH_SYSTEM_COMPLETION_PACK

Phase 5C2 remains paused.

Key facts accepted

birth_registry_row_count=208537
birth_null_species_count=0
birth_trigger_count=33
collections_governed_count=166
collections_with_birth_trigger=29
collections_without_birth_trigger=137
species_count_live=41
species_collection_map_count=154
required_at_birth_supported_count=9/10
required_hook_supported_count=7/7
information_unit_birth_coverage=100%

Decisions

Decision 1 — 137 collections without trigger

Do not blindly add triggers to all 137 immediately.

But also do not ignore the gap.

Correct policy:

Every governed collection must have either:
1. birth trigger coverage; or
2. explicit birth exemption with reason; or
3. deferred status with owner/date/condition.

Create a birth coverage classification:

BIRTH_REQUIRED
BIRTH_EXEMPT_STRUCTURAL_JUNCTION
BIRTH_EXEMPT_SYSTEM_LOG_OR_AUDIT
BIRTH_EXEMPT_DERIVED_CACHE
BIRTH_DEFERRED_NEEDS_REVIEW

No governed collection may remain silently uncovered.

Decision 2 — birth_owner_ref

Owner is conceptually required for Entity Living DB and governance, but current birth_registry lacks birth_owner_ref.

Policy:

Owner must be part of the birth contract.

Implementation should not assume every source table has the same owner column. Use owner resolution:

source record owner-like fields → source collection owner policy → collection_registry owner/governance owner → UNKNOWN_OWNER

Recommended schema direction for later implementation design:

birth_owner_ref nullable text/uuid-like field
birth_owner_resolution_status or JSONB metadata profile

Exact DDL not approved yet; design first.

Decision 3 — canonical_address

Do not require physical canonical_address column on every collection.

Universal address contract should be:

entity_birth_address = collection_name + entity_code

canonical_address physical column is required only for addressable content/native IU-like entities, not all collections.

Policy:

Canonical address is REQUIRED for IU/content-addressable entities.
For general governed entities, collection_name + entity_code is the universal birth address unless a stronger canonical field exists.

Decision 4 — 8 relationship rules

Use the exact 8 relationship rules confirmed from layer3-information-law.md:

IDENTITY
BELONGS_TO
CONTAINS
DEPENDS_ON
USED_BY
TRANSITIVE
PEERS
SIMILAR

Do not add new rules casually. Birth must create hooks/placeholders for the 8 rules, not materialize all relationships at birth.

Decision 5 — 5C2

IU birth coverage is clean, so technically 5C2 pilot can be made safe later. But the current mainline remains Birth System Completion.

5C2 may resume only after B2 contract is finalized and GPT/User decides whether to run IU pilot in parallel.

Required next action

Open:

P3D_BIRTH_SYSTEM_COMPLETION_B2_CONTRACT_AND_COVERAGE_CLASSIFICATION

Opus should create B2 contract design, not implementation.
