# Mission Evidence

`GET /missions/{mission_id}/evidence/{task_id}`

Serve the sealed evidence bundle behind a timeline element's provenance link.

``bundle_hash`` is recomputed from the canonical binding bytes on every read,
so the drawer always shows the bundle's current identity -- and a bundle that
no longer matches the hash a phase receipt bound projects that phase as
unverified in the mission projection above.
