User reproduced on WH/JOB/00342: clicked Start on Incoming Inspection
while Contract Review was still in_progress. Sub 13 should have raised
UserError. It didn't. Both steps ended up in_progress.
Investigation:
$ grep "def button_start" fusion_plating_jobs/models/fp_job_step.py
88: def button_start(self): ← Sub 13 gate code
876: def button_start(self): ← Policy B + Sub 8 (older)
Two definitions of the same method in the same class. Python uses the
SECOND. My Sub 13 gate at line 88 was dead code from the moment it
landed. WH/JOB/00342's Contract Review and Incoming Inspection both
ran in_progress because the live button_start (line 876) only did
Policy B Contract Review auto-open and Sub 8 Racking auto-open — no
predecessor check.
Fix:
* Removed the duplicate button_start at line 88 (left a marker
comment so the next person doesn't redo this footgun)
* Merged the Sub 13 predecessor gate AND the receiving soft check
into the line-876 button_start so all four behaviours run from
one method:
1. Predecessor gate (raise UserError if blocking)
2. Contract Review auto-open (route to QA-005)
3. Racking auto-open (route to inspection)
4. super().button_start() + receiving check + serial promotion
Helpers _fp_should_block_predecessors / can_start / _compute_can_start
preserved (used by view + Move wizard too).
