+
+## Task
+
+Fix 5 issues in the install/update flow: hardcoded git URL, `.venv` cwd bug, Windows venv path, hook copy-vs-symlink inconsistency, and missing `--version` smoke test.
+
+## Deliverables Review
+
+| Requirement | Status | Evidence |
+|---|---|---|
+| R1: User-supplied git URL (D11) | DONE | `install.sh` `GIT_URL="${1:-}"` with usage and irreversibility warning, 4 tests |
+| R2: Fix `.venv` cwd bug | DONE | Venv in `$FRAMEWORK_DIR/.venv`, `requirements.txt` from `$FRAMEWORK_DIR`, 4 tests |
+| R3: Windows venv path | DONE | Platform-aware `VENV_PY` detection, `-m pip`, 4 tests |
+| R4: Hook copy-vs-symlink | DONE | `update.sh` and `upgrade.sh` use `cp` + `chmod +x`, 6 tests |
+| R5: `--version` smoke test | DONE | `status.py --version` after install, 1 test |
+| R6: Tests | DONE | 15 tests in `tests/test_install_update_flow.py`, all passing |
+| R7: Documentation | DONE | CHANGELOG and README updated |
+

+
+## Verdict
+
+**APPROVED -- ready for complete.**
+
+All 7 requirements fully implemented, tested, and documented. The install/update flow is now portable, secure, and consistent.
