feat: D19 bounds the review loop; apply nine rulings; close Q46(a) and Q48–Q53

D19 into §3 and swept to all six destinations Pouya named: both agent briefs
(scope + severity filter), /build Phases 2–4 (non-gating questions, scope, stop
signal, two-round cap), /wrap, and CLAUDE.md (comments record decisions, not
history). Sweep verified by command, not recalled.

Rulings applied:
  Q46(a) PUBLISHABLE — three §4 Offerings rows flipped; gate 1 records
         [Pouya's stated basis], never [verified]. Step 5 unblocked.
  Q48    closed, not site-relevant.
  Q49    one §4 row, "Mediator"; read as declining Q49(b), so worksFor stays out.
  Q50    DEVIATES — ships as name + slogan, not the concatenation. Flagged.
  Q51    OBA sections stay; the regulator/voluntary distinction recorded.
  Q52    docs/reference/deploy-credential-verification.md — 18 read-only AWS
         calls, re-run rather than transcribed, access key ID redacted.
  Q53    memberOf emitted on /about/'s Person node.

Two review rounds. The headline finding was this session's own: the Q53 sweep
was asserted and never run, leaving six in-scope records saying memberOf was
withheld — including §12 R10, which is read aloud every session. Round 2 then
found that round 1's simplification had put memberOf on / as well; the per-page
opt-in is restored, because Pouya's ruling turns on /about/'s visible HTML.

Also fixed: MEMBERSHIP_ORGS had orphaned BOUTIQUE's D16 JSDoc; /'s title now
derives from the constants; §7's deploy row stated and retracted three facts.
