The wipe script lived only on prod, untracked, which is why this was
invisible: it deleted every mission and agent and left every per-repo
.brain intact. Those files are in no table and no cascade reaches them,
so agents kept recalling verdicts from missions that no longer existed —
measured 2026-09-22, an 18,982-byte repo brain outliving its rows, and a
harness assertion that failed on the correct behaviour because it asked
the database what the brain remembered.
Now tracked in the repo, and it clears /data/brains/*.h5 after the agent
purge so "clean slate" means what it says. CLAWMATES_KEEP_BRAINS=1 keeps
the old behaviour for when accumulated project knowledge is worth more
than a blank start.
Also documents what deliberately SURVIVES and why: corpus_items (the
research seen-set, so a fresh harvest does not re-download papers
already covered), judge usage rows, skills, repos, team_templates and
nodes.
