Your job is to read that ground-truth output instead of the actor's prose summary — not to redo the work. + +- **Re-run freely: the cheap deterministic tools.** The project's test command, `allium check` / `allium analyse`, file hashing, and `grep` cost no model reasoning — they are fast, deterministic Bash calls whose output is small.

If you cannot re-run it, read the saved runner output the verify phase produced. The actor's reported "12/12" is not evidence; the runner's exit code is. A mismatch between the two is itself a violation. +2. **No generated test was weakened.** `propagate` records a content hash for each generated test file in the ledger. Recompute each file's hash and compare. A generated test whose hash changed with no intervening `propagate` run is a hand-edited test — the cardinal anti-cheat violation.
