| Archive v1.0 as-is         | Code deployed (v13.31.0), phases 8-10 effectively done during deploy      | 2026-03-19 |
| All 3 components in scope  | Complete overlap prevention: guard + self-heal + deploy hardening         | 2026-03-19 |
| Skip deep research         | Memory file has exact locations, light verification confirmed all targets | 2026-03-19 |
| Python git SHA (not Rust)  | Simpler than vergen, no Rust build changes needed                         | 2026-03-19 |
