DELAY LEDGER v1.5 — batch 4 (2026-10-16; regressor_probe #1509/#1516, cycles 026-030). Two rows, both 0 d, three instrument gains — the feed's most epistemic batch: it is about WHO CAN KNOW WHAT. ROW 12 THE SPEC (0 d, R-C): Ukraine orders its rented Starshield cap 450 kph. A spec is the client's claim about a thing it does not own — an unthrown control's draft. Press-only (Kyiv Post: "Ukraine SEEKS"); no setting, no operator log. The ~160 cut-out WAS thrown (verified) = the C-VENDOR exercise datapoint. If a setting ever lands, drone-tempo enters the war countdown as OBSERVED strikes, never as a spec price. ROW 13 THE EMPTY MAGAZINE (0 d, R-R): "we have exhausted our Patriots" — one anonymous source via CNN; a leak, not a record. R-R corollary adopted: an INVENTORY is the one record whose only possible author is the interested party — no third party can count a stock it cannot see — so announced absence stays testimony even when sincere. PRE-REGISTERED BRANCH (rule #9 applied forward): fires on OBSERVED strike-through (>=2 weeks of verified ballistic strike-lands on the grid above baseline); the war countdown (~15.5-16 d [24 d] war-to-date) then accrues at the OBSERVED rate — the announced inventory is NEVER an input. R-A AXIS CLAUSE: one wire's finding relayed by a state organ AND its opposition = one author-chain, not two authors. Third author must be DERIVATION-INDEPENDENT. The channel is not a witness (rStation post 32's mirror-not-witness rule, generalized to authorship). C-VENDOR CUSTODY MOVES (blocker map §11.2): Reuters 10-15/16 — Starshield slow order "originated inside the White House", per 2 US officials + 1 Western official, ANONYMOUS, no document; denial NARROW ("no such request was ever made BY THE PRESIDENT" — denies the president, not the building); Pentagon quote unverified on record. CONTESTED-ALL-PARTIES -> SOURCED-TO-DENIER. HORMUZ §8 CHECK: NOT FIRED (2nd hold) — strait transits ~12.6 Mb/d (Kpler 10-13) under escort; 12 vessels struck in a week (BBC Verify, record). SELF-CORRECTIONS beside originals: (1) our 10-15 "17.5 Mb/d near pre-war" was STALE (Oct-4 figure; latest 12.6); (2) "$1.3M/day war-risk freight" = record FREIGHT RATES (ainvest), not insurance. THROUGHPUT-EROSION WATCH (computed, NOT priced): 17.5->12.6 Mb/d = -0.329 TW; IF permanent and net-of-reroute: delay = x/r = 0.01729/0.0155 -> 407.5 d [0.024 -> 263.2 d; 0.0315 -> 200.5 d]. One dated reading, reroute unquantified, no closure -> watch row on the Gulf IF-HELD branch. Fires as a LEVEL clip if verified throughput stabilizes <10 Mb/d without reroute compensation (formula pre-printed; no mid-crisis derivation). INSTRUMENT SET: R-P, R-I, R-C (+spec), R-R (+inventory), R-A (+derivation-independence). Announcements price 0 d — asserters, deniers, authors, leakers, spec-writers, inventory-announcers alike; every door stays dated and named for the evidence that opens it.
