HeliosForge Bio-Attribution Series: Irkutsk Anti-Plague Institute Death — Equal-Weight 5D Branch Ledger, Wild-Type Shelf, Stage Cards, and Measuring Desk
Year: 2026
Type: preprint
Abstract: Decision-desk volume in the HeliosForge Bio-Attribution Series, dated 6 October 2026, containing the 5 October 2026 working papers. For the decision desk. Not a diagnosis. No leaf is retired. The volume does not edit the 1 June 2026 Bundibugyo paper or the 11 May 2026 MV Hondius originals. It does not specify how to acquire, grow, modify, aerosolize, or resistance-engineer an organism. Mitigation is the product. What happened, as graded. Darya Shipilova, 28, a technician at the Irkutsk Anti-Plague Research Institute of Siberia and the Far East, was admitted in Shelekhov on 29 September 2026 with severe pneumonia, initially treated as possible COVID, later ventilated, and died in the early hours of 2 October. Rospotrebnadzor called the illness pneumonia of undetermined etiology, said no work-linked organism was found, and said no accident was recorded. Contact samples included two COVID-19 and two rhinovirus findings. Governor Igor Kobzev said identified contacts had tested negative and that the situation was stable. Nearly 200 people were under observation; more than 60 institute staff were reported isolated. Alexey Tsydenov, head of Buryatia, posted that she died of plague and then edited the post to possibly, and said she had not come to Buryatia. Gennady Onishchenko said the infection was most likely not plague. Dmitry Peskov said to follow Rospotrebnadzor. No public isolate, autopsy, itinerary, or secondary case is in this volume. Four origin accounts stay open at equal initial weight. A broken tube of live material on 25 September, reported by Lyudi Baikala and Mash and cited by The Times, RFE/RL, The Independent, and New Scientist. A Buryatia field trip, reported by Mash and by the BBC as a recent visit to a marmot-endemic area, denied or revised by Tsydenov. An undated Thailand return via Bangkok, reported by Echo through a Lyudi Baikala healthcare source and by Meduza, and denied by a Rospotrebnadzor commission as quoted by bne IntelliNews. An unnamed working trip, reported by Zvezda and not reopened. A missing same-day antibiotic course keeps a transport leaf open beside the tube. It does not prove a modified organism. How the engine is built. The volume uses the nine-module HeliosForge bio engine already used on the Hondius and Bundibugyo papers. Module 1 holds graded facts. Module 2 holds published wild-type sequences and host animals for the places the open arms name, and does not assign her a genome. Module 3 holds the organism card, the three clinical doors, and the stage pathology. Module 4 holds the equal-weight branches. Module 5 reads the clock and the infectivity weight. Module 6 hangs a reported story on a stage. Module 7 reads transparency. Module 8 reads the seclusion class. Module 9 is the measuring desk. Module 2 stays empty of her sequence until an isolate exists. Five dimensions. Time is the exposure window against the 29 September admission and the 2 October death. Place is the bench, Buryatia or the Mongolia border, an undated Thailand return, a ward, an ambulance, or a cabin. Route is flea or tissue, close droplet, or a shared-air label that widens the ring and dies if no case appears outside cough range. Face is wild-type versus an unconfirmed wider face, held as a scenario label only. Transparency is whether the isolate and the contact map are released. While they are not, the transparency term stays low and no arm is allowed to collapse. Clocks used as the collapse tool, not as a diagnosis. Bubonic incubation is usually 2–8 days and is not person-to-person until the lung seeds. Primary pneumonic incubation is usually 1–3 days, about 1–6. The first day after lung seeding is treated as noninfectious. Untreated pneumonic disease is often fatal within about 18–48 hours of respiratory onset. The prophylaxis ring is close contacts from the prior 7 days. A 25 September exposure to a 29 September admission is about four days, which fits a primary pneumonic clock better than a long bubonic course, but does not kill the field-bite arm if symptoms started later than the tube date. A Thailand return inside 23–28 September would sit inside that pneumonic window and is run as a coughing leg until a passport or a flight date falls outside it. Lincoln at Laem Chabang in early September is outside a 1–6 day window for 29 September. Bush at Phuket on 4 October is after death. Neither ship is wired to her. Phuket cannot be her exposure site. Wild-type shelf, not a hit. M2-A is the Baikal and Buryatia marmot face, Marmota sibirica, vector Oropsylla silantiewi. M2-B is the Mongolia marmot, gerbil, and jerboa face from Riehm and colleagues. M2-C is the 2023 Altai and Tuva antique biovar, adjacent, not Irkutsk. M2-D, Thailand, is empty on purpose: no endemic wild-type sequence to inherit. M2-E is an unnamed institute collection, with no public accession. Ancient Cis-Baikal reads and the 2026 Baikal hunter-gatherer paper are landscape context, not a Shelekhov genome. The pneumonic comparator is Moramanga 2015, R0 1.44, infectious period 3.5 days, used as a published close-contact figure, not as her strain. A Bangkok cabin does not inherit 1.44. It inherits the Stage 2 ring rule. What the desk measures. Eighteen leaves start at equal weight. A negative Lyapunov score means the named people are caught. It does not delete the leaf. The cover sheet pulls rings B1–B18 as Reported or Scrape-target: respiratory isolation only, bench plus ward, same-room staff, seatmates if a flight is dated, ports refetched but not sequestered, field mates named but the town not locked, emergency staff held in Stage 2, plague precautions held until a written negative, household only, both facilities named, luggage contacts only if a shared bag is named, suite air named with the arm left open. On the 5 October run, SCET closed is 3.66 and SCET open is −1.17. No second death is printed. A blank validation row is not a pass. What would actually close a leaf. A local-rodent clade match with no accident record raises the field arm and drops the bench and wider-face arms. An institute-collection match or a documented 25 September spill raises the tube arm. No Yersinia pestis, with a routine pathogen explaining the death, raises ordinary pneumonia and drops the plague arms. A passport inside the incubation window raises the Thailand arm; an empty passport drops it. Illness only in cough-range contacts drops the shared-air reading. Illness in shared-air contacts with no cough-range link keeps that reading open. A public isolate raises transparency and lets arms die. Contacts still well past about 9 October are outside a primary pneumonic incubation from the admission date. That sentence is a clock, not a clearance. Context that is recorded and not wired. Heilongjiang Daily, 3 September 2026, reported a China–Russia drill in Fuyuan: imported bubonic plague, tick-borne Disease X, 19 teams, more than 300 personnel. The Russian units named are Rospotrebnadzor and experts from Khabarovsk, Amur, and Primorsky. The Irkutsk director and the Event 201 players are not on that page.
