# V2 Program Closeout

Status: Complete

## Completed phases
- V2-P0 kickoff baseline
- V2-P1 spec/invariant lock
- V2-P2 trigger authority cutover
- V2-P3 transactional hardening
- V2-P4 surface/schema embodiment closure
- V2-P5 integration framing + legacy classification
- V2-P6A authority cutover completion
- V2-P6B semantic closure + cleanup
- V2-P7A authority completion follow-through
- V2-P7B semantic/store completion
- V2-P7C final shim cleanup/docs consolidation

## Final posture
The codebase has moved from transitional/documented intent to implemented target architecture with:
- canonical runtime center
- session-first live authority semantics
- index projection demotion
- canonical rolling record continuity surface
- explicit association data-model separation (edge/association class, no association bead type)
- SpringAI-first bridge framing with compatibility ingress retained
- explicit shim/deprecation markers and fences

## Validation summary
- Full regression: 193/193 passing
- Eval snapshots: stable through final phases

## Note
Compatibility seams remain where intentionally retained for operational safety, but they are explicit and non-authoritative.
