Use when an actor enters, occupies, peeks, fires from, and exits authored cover and needs one cover-session state machine with explicit interruption and ownership handoff.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cover shooter Ask: `stick-cover | tap-cover | soft-cover`. ## Ownership `cover-shooter` owns the actor's cover-session state. `cover-space` owns valid anchors/capabilities; `projectile-hitscan` owns shots; `aim-assist` / `fps-feel` own aim/handling; `input-design` owns bindings. ## Contract Publish: - stable `cover_session_id` - actor ID and `cover_anchor_id` + revision - state: enter / attached / peek / fire / exit / aborted - movement-control owner - authored transition/cancel conditions - optional stance/fire-side selected from anchor capabilities Exactly one system owns the actor's cover locomotion at a time.

This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
