## Implementation Summary
- Raised SQLite schema version to `11` and added additive/idempotent `review_decisions` and `reconciliation_sessions` schema objects.
- Added `review_decision_service.py` for safe non-destructive review decision and reconciliation session operations.
- Added payload minimization to prevent raw payload/password/token/secret/file-path persistence.
- Added review/session state enrichment to cross-transfer queue, balance reconciliation report, and uncategorized workbench outputs.
- Added MCP tools for list/upsert/hold/recheck/release review decisions, list/upsert/close reconciliation sessions, and review operating indicators.
- Added Streamlit actions and gateway exports for review decision/session workflow state.
- Added regression tests for schema idempotency, sensitive payload filtering, reconciliation session round trip, report integration, and MCP tool surface.

## Commands and Results
- `python -m ruff check .` → passed.
- `python -m pytest tests/test_review_decision_workbench.py -q` → `.... [100%]`.
- `python -m pytest -q` → passed, with existing skipped tests preserved.
- MCP surface smoke: required 9 review/session tools present; destructive delete/reset absent; tool count `65`.
- DB safety smoke: schema version `11`, `PRAGMA integrity_check` `ok`, new tables present and empty on synthetic DB.

## Notes
- No production DB destructive operation was performed.
- No raw financial evidence or secrets were added to repository fixtures.
- Final PR/CI evidence remains the next gate after commit/push.
