`Q53` labels two live items: the career-lane apply queue at `:7303` (seven
decisions held for Alexander) and Mercury's record at `:8530`. Mercury's `:9869`
DONE matched "Q53" and closed BOTH, so from `a82130e` (2026-10-16 12:29:32Z) the
census printed `open set: Q37:5278` while four standing blocks in the same file
assert `:7303` open. Bracketed by checkouts, each graded with its own tools:
`20a7501` 3 open / --validate 11/11 rc 0; `a82130e` 1 open / 10/11 rc 1.
Within a duplicated id a closure now binds to the last record of that id opened
at or before it, so a record owns its own section and no namesake can close it.
Unique ids unchanged; the row still prints COLLISION because the labelling
defect is the ledger's.
Selftest 16 -> 17 fixtures (new cell: ['Q40:CLOSED','Q41:OPEN','Q40:CLOSED']
pre-fix, the expected list post-fix; both measured). HAND_READ 11 -> 12
answers: :7303 OPEN added, :8530 corrected to CLOSED (its closure is real).
--validate rc 1 -> rc 0, 12/12.
Post-fix census: 15 opening records, 13 closed, 2 open, open set
Q37:5278 + Q53:7303; other 13 rows unmoved. doc_census_check on this tool: 19
claims, 0 STALE, 0 split, 0 leg failures. Queue block appended and
docs/queue-index.md re-rendered in this same commit.
