 - Replacement readiness is evidence-based, not aspirational
 - Users have a command/API migration path
 - Remaining gaps are explicitly owned by the correct repo
+
+## Implementation
+
+- Added `docs/legacy-command-parity.md` with the legacy command migration table
+  and replacement examples.
+- Added `docs/legacy-infospace-migration-guide.md` and
+  `docs/replacement-readiness-decision.md`.
+- Added replacement gate CLI commands: `status`, `check`, `viability`, and
+  `graph`.
+- Added deterministic `bootstrap-readiness` workflow fixture.
+- Added `tests/test_replacement_readiness.py` covering both pilots, the CLI
+  gate, migration docs, and the decision record.
+
+## Verification
+
+- `python3 -m pytest tests/test_replacement_readiness.py`
+- `python3 -m pytest`
