FORM
 A Cirstea: W vs Bejlek 6-1 7-6 (GRIND, 1d ago). Clay season loaded:
   SF Rome beating Ostapenko(1890 DOM), Noskova(1790 DOM), set off Sabalenka(2052);
   QF French Open. Beats STRONG/ELITE regularly — genuinely higher-tier.
 B Birrell: Eastbourne TITLE 6/21, then R1 Wimbledon vs Korneeva 6-3 0-6 6-2 (GRIND, 1d ago).
   Real grass scalps: bt Krejcikova(1871), Pegula(1917). Capable but streaky.

FATIGUE
 A: 1 match / 3 sets / 64min in 14d — FRESH.
 B: 5 matches / 15 sets / 331min in 14d, back-to-back 2 — HEAVY.
 Diff 267min (>60) → strong disadvantage to Birrell.

NARRATIVE
 Let-down (B): won Eastbourne Final 6/21 (WEAK window, 11d) — title legs mostly recovered
   but the 5-match grass grind since is the real drag.
 Title recency (B): Eastbourne 11d ago (grass) — form is real, not the killer.
 Venue: neutral, both fresh to Wimbledon this yr.

VERDICT — PASS
 Model's Birrell "edge" rests on a stale ELO (0.361) that undervalues Cirstea's
 run over Strong/Elite clay fields. Qualitative read flips it: Cirstea is fresher
 (64 vs 331 min) and higher-ceiling. But 1.35 on A is too short to back with a GRIND
 R1 behind her — no value either way. No bet.
