pan task

Run the requested task command now. Task state belongs to one issue's xBRIEF checklist, recorded in .pan/continues/<issue>.xbrief.json in the project repo (or the configured plan-home repo for polyrepo projects) — never a tracker or pipeline record.

pan task next PAN-123
pan task show PAN-123 PAN-123-a
pan task claim PAN-123 PAN-123-a
pan task done PAN-123 PAN-123-a
pan task block PAN-123 PAN-123-a
pan task unblock PAN-123 PAN-123-a
pan task cancel PAN-123 PAN-123-a

block/unblock/cancel only flip the item's status in the continue file — there
is no --reason flag or free-text note field. Say why in the issue/PR conversation
if a reason is worth recording.

pan task claim records the claim in the continue file. Commit exactly one xBRIEF item at a time with the commit trailer Item: <item-id>, and push the feature branch immediately — before running pan task done. An unpushed item can be lost before Overdeck can see it.

pan task done <item> then verifies a commit on the pushed feature branch carries Item: <item-id>, and commits the item's status into the continue file. It refuses if the branch isn't pushed or the trailer is missing.
