feat: Phase 5A — Engineering V1 foundation
First slice of the Engineering V1 sprint. Lays the schema + lifecycle
plumbing so the 10 canonical queries, memory graduation, and conflict
detection can land cleanly on top.
Schema (src/atocore/models/database.py):
- conflicts + conflict_members tables per conflict-model.md (with 5
indexes on status/project/slot/members)
- memory_audit.entity_kind discriminator — same audit table serves
both memories ("memory") and entities ("entity"); unified history
without duplicating infrastructure
- memories.graduated_to_entity_id forward pointer for graduated
memories (M → E transition preserves the memory as historical
pointer)
Memory (src/atocore/memory/service.py):
- MEMORY_STATUSES gains "graduated" — memory-entity graduation flow
ready to wire in Phase 5F
Engineering service (src/atocore/engineering/service.py):
- RELATIONSHIP_TYPES organized into 4 families per ontology-v1.md:
+ Structural: contains, part_of, interfaces_with
+ Intent: satisfies, constrained_by, affected_by_decision,
based_on_assumption (new), supersedes
+ Validation: analyzed_by, validated_by, supports (new),
conflicts_with (new), depends_on
+ Provenance: described_by, updated_by_session (new),
evidenced_by (new), summarized_in (new)
- create_entity + create_relationship now call resolve_project_name()
on write (canonicalization contract per doc)
- Both accept actor= parameter for audit provenance
- _audit_entity() helper uses shared memory_audit table with
entity_kind="entity" — one observability layer for everything
- promote_entity / reject_entity_candidate / supersede_entity —
mirror the memory lifecycle exactly (same pattern, same naming)
- get_entity_audit() reads from the shared table filtered by
entity_kind
API (src/atocore/api/routes.py):
- POST /entities/{id}/promote (candidate → active)
- POST /entities/{id}/reject (candidate → invalid)
- GET /entities/{id}/audit (full history for one entity)
- POST /entities passes actor="api-http" through
Tests: 317 → 326 (9 new):
- test_entity_project_canonicalization (p04 → p04-gigabit)
- test_promote_entity_candidate_to_active
- test_reject_entity_candidate
- test_promote_active_entity_noop (only candidates promote)
- test_entity_audit_log_captures_lifecycle (before/after snapshots)
- test_new_relationship_types_available (6 new types present)
- test_conflicts_tables_exist
- test_memory_audit_has_entity_kind
- test_graduated_status_accepted
What's next (5B-5I, deferred): entity triage UI tab, core structure
queries, the 3 killer queries, memory graduation script, conflict
detection, MCP + context pack integration. See plan file.
