Skill activation triggers

Run Planning to freeze phases and return paths. Run DevOps for digest-pinned promotion and canaries. Run Testing for parity/integrity windows. Run Security whenever data class or access paths change mid-move.

Verification that skills worked

• Each phase has an explicit rollback owner and command
• Dual-write or verify window evidence exists before irreversible drops
• Secrets never appear in migration scripts committed to git

Changelog

• 1.3 (2026-07-29): Migration skill activation and verification rewritten for this envelope.
