TASK-056: capture unworked review issues report

Validation loop produced 8 unworked majors and 40 minors after three
iterations (10 critical/major findings fixed in iter 1, 1 in iter 2).
The remaining majors are non-blocking judgment calls from the
code-simplifier (dead alias variable, redundant collision-flag
assignment in reject_terminus_collision) and minor follow-ups across
agents.
