# V2-P8C Closeout Checklist

Status: Complete

## Scope
Retrieval / Schema Closure (P8C): schema authority map hardening, retrieval contract normalization, path-purity enforcement, and compatibility invariants.

## Completion checklist
- [x] Retrieval schema authority anchors codified
- [x] Runtime retrieval wrappers normalized with stable schema/contract defaults
- [x] Retrieval path purity guard added
- [x] Compatibility invariants expanded for search/execute wrappers
- [x] Step 5 regression sweep completed

## Regression evidence
Command:

```bash
python3 -m unittest \
  tests.test_search_form_module_primary \
  tests.test_memory_search_tool_wrapper \
  tests.test_memory_execute_contract \
  tests.test_memory_execute_feature_flags \
  tests.test_memory_execute_surface_metadata \
  tests.test_p8c_retrieval_path_purity \
  tests.test_p8b_read_path_purification \
  tests.test_continuity_injection_authority -v
```

Result:
- 12 passed / 0 failed

## Final retrieval/schema authority stance
- Search form schema authority: `core_memory.retrieval.search_form`
- Canonical runtime retrieval surface: `core_memory.tools.memory::{get_search_form,search,execute}`
- Compatibility-only retrieval shims: `core_memory.tools.memory_search`, `core_memory.memory_skill.form`
