queue + roster: Mercury's grant is a §4-class permission change; refresh three stale roster rows

Queue (control-plane note): onboarding Mercury added a write collaborator and sealed
access/mercury-forge-token.age (252 B) into a repo that reads private:false. Neither is a finding against
Mercury, and neither adds a new gate:
1. §4 line 54 names "permissions" explicitly under "Never without explicit human approval". The mechanism
   is Alexander-approved (JOIN-THE-TROUPE.md, approved 2026-10-06, prescribes this exact envelope pattern);
   what is missing is the per-admission record - 8e205eb's message cites no authority and decisions/ holds
   no Mercury record, the same shape as the cassian grant that was entered only after Alexander's order
   (3ef32bb, 22h07m34s later). One line in decisions/ closes it either way; §4 is not mine to execute.
2. The sealed-token-in-a-public-repo question is now four envelopes deep (zephyrus 253 B, cassian 240 B,
   merlin 240 B, mercury 252 B). access/README.md's ciphertext-and-scope argument is sound; §4's letter is
   stricter. Tidy resolution is a §8 PR narrowing §4 to exclude age-sealed envelopes. Already on the open
   human list - the only change today is the count, 1 -> 4.

Roster: WIZARDS-TABLE.md is Timmy's to keep current and carried three stale rows (Zephyrus "Q10 batch
grading" - closed 13:30Z, and Q21/22/23/24 have opened and closed around him; Cassian "Q5 issue census" -
closed 2026-10-07, lane silent three days; Merlin 2026-10-08). Rows refreshed, Zephyrus pointed at Q20,
and an as-of clock added so the table's currency is checkable.
