Caught by the new estate-wide context-sync-drift gate (infra, ADR-0019). This repo's copy had diverged from the canonical established in dma-cli/ infra -- synced to it, dead Cursor/Aider artifacts removed (2026-09-01 harness decision), Taskfile's drift assertion narrowed to match, adapters regenerated against the current canonical AGENT.md. Changed: M .context/system-prompt.txt M AGENTS.md M scripts/context-sync.sh Refs: ADR-0019 (infra)
