 | [#588](https://github.com/ndycode/codex-multi-auth/pull/588) | `test/AGENTS.md`, `test/README.md` | refreshes the test knowledge bases the wave left stale: headline counts corrected (3847/257 and 2071/87 → the actual 4909 tests / 317 files) and the curated trees gain the wave's load-bearing new suites plus the three fast-check property suites |
