- Sequence: add noupdate="1" to fp_job_sequences.xml. Without it,
every module update resets number_next to 1, corrupting the live
job-number stream. Matches fp_sequence_data.xml convention.
- action_cancel now raises UserError on an already-cancelled job
instead of silently rewriting state. Audit-grade traceability
expects explicit failures.
- Added TODO marker for action_hold / action_resume /
action_revert_to_confirmed so future authors don't bypass the
state-machine guards.
- Tests: added cannot_cancel_done (covers the dead-code UserError
branch) and cannot_cancel_already_cancelled.
Manifest version bumped 19.0.8.2.0 -> 19.0.8.2.1.
