S13 - already fixed at T1.6; the records said otherwise, now corrected

The housekeeping list carried S13 ('seed_demo.py does not sign in') from
completion.md and CLAUDE.md. It is not true and has not been since wave 1:
T1.6 (357712e) rewired seed_demo.py onto smoketest's opener - one cookie jar,
one login flow - and the file's own docstring says so. What actually happened:
the wave-1 exit checkbox was never ticked, and every later document inherited
the unticked box as fact.

Verified live before correcting anything, per the working rules: against a
throwaway server, seed_demo.py signs in as an admin, seeds the DEMO project
(7+ packages visible via the API), and --clean removes it, exit 0 both ways.

Corrected: the wave-1 exit box (ticked, with the reason), completion.md's S13
row (open -> built at T1.6, records error named), and CLAUDE.md's
verification step 4, which taught every future session the stale claim.

Item: S13 (closed as already-built; records corrected).
