copybot: FLIP #20 + #21 — entry_mode=maker, exit_mode=hold on both books (forward windows open at this commit)

User-directed flip 2026-07-23 (ahead of the Friday read; the user go is
the gate, per both pre-registrations). Maker entries: GTC at the sharp's
price, 60s registry TTL, no chase. Hold-through: mirrored exits ignored
and ledgered to copybot_ignored_exits[.live].jsonl as the live
counterfactual. Verdict bars unchanged: #20 keep/revert at n>=30 resolved
(fill>=70% or ROI>=parity edge / revert fill<55%@40, ROI<=0@30); #21
keep/revert at n>=30 resolved ignored-exits (hold>=mirror / revert
-$50@30 or 25% attributable DD).
