First live run: a canon whose recorded code opens with a call-site example
(confirmed()'s onTrash) made every `async function x(): Promise<void>`
resemble it at 0.86, and the write-path semantic floor paired alembic
upgrade()/downgrade() bodies with unrelated canons at 0.68-0.75. Rows now
remember (body, ruleset) so a tightened rule looks again once.
