Session F (night2): Phase 5 — records + dossier

5.1 Archetype defined on-page: one line from the archetype library under
    ARCHETYPE DNA (BOMBER — elite raw power…); expander keeps the long form.
5.2 VYNDR-on-team live: getModelAggregate team scope (migration-020 column)
    + /api/ledger/model?team= + ModelRecord mounted on the Team Hub header.
5.3 WNBA/NBA profile parity: minutes-based usage (+MIN season cell) when
    the feed carries minutes — absent beats invented.
5.4 Settings read meter: real rolling-24h usage from the SAME store the
    limiter enforces (GET /api/user/scan-meter + proxy). Metered tiers see
    'X of N reads today' + bar; unlimited tiers see nothing. Corrects the
    stale '5 scans / month' copy.
5.5 Per-tier calibration on the MODEL tab: A+/A/B/C chips with hit% at
    n>=20 PER TIER, 'building (n/20)' below — the separation between tiers
    is the proof the grades mean something.
