Prepare requested immutable historical snapshots before timed extraction and direct reads, using the existing acquisition/process helpers and local-only consumers. Move four suites' historical module setup into per-pin hooks without changing pins, compatibility assertions, workers, extraction/assertion deadlines or publication ownership. Independent reviews and the binding design settlement passed. The cold comparison and normal uninstrumented final-head CI each passed49files197tests; normal Checkout62s/job276s. All temporary probes removed; brennan-ready READY. Tracked in STA-13683. Outer-hook failure attribution limitation tracked in STA-13703. No application, saved-data or wire behavior change.
