Re-verify the three primitive schema docs against the installed apm-cli 0.28.0 source and live installs, and add an authoring checklist to each. Corrections to the earlier docs: - Copilot hooks are not reshaped: events are renamed, paths rewritten and version: 1 added, but command/timeout are not renamed to bash/timeoutSec. - A malformed .claude/settings.json is overwritten on install, losing user content. - Instruction validate() messages are warnings only; apm compile --validate never fails on them.
