All answers were sealed before the open: the latest — Gemini, 13:23:29 UTC (6 min 31 s before the open); the others — at 13:00:17 UTC.

Covers lines 253–264 of the Council’s book (the run’s lines). Sealed 2026-10-22 13:00:16 UTC, seal updated 2026-10-22 13:23:26 UTC.

A new line only adds to the book: its lines 1–261 keep the same bytes in every later list, sha256 8b205f9e54364615e6c82d6aa84647e081aa8580a9ae165478cc73f831ca50c5

The intake for the score closed at Thu, Oct 22, 2026, 9:30 AM ET (2026-10-22T13:30:00Z). Each model's line sealed last before it counts (marked below); a line sealed later is scored from its own reference price, the first price after its seal.

The run’s day, step by step
  1. prices snapshot
  2. the question and the roster sealed, the question sent
  3. answers sealed, the last at 13:20:07 UTC
  4. hash of the run sealed
  5. seal updated with the run’s next line
  6. the open: intake closes, reference prices
  7. Bitcoin block 972621 (header time, ± up to ~2 h)

What the lines are. The forecast score takes the issue's answers (lines “answer”), one line of each model — marked below. Lines “bench” are decisions of the AI Portfolio League (the league and the Pro league): they go into the league, not into the forecast score. One model can have both: a forecast in the morning and a new league decision later.

Every line of the book (daily/council/book.jsonl) is chained by sha256 (seal / prev / link) and the books are stamped in OpenTimestamps by the engine. The texts of the lines are published after the score of the day.

Who is in the league in this issue

The roster is sealed in the run line (n=254) before any answer. The Council gives the forecasts and trades in the league; the bench trades in the league only. The roster as one file (JSON) →

Stamped lists (OpenTimestamps)

Check without us — or both files on opentimestamps.org: ots verify <file>.txt.ots · shasum -a 256 book.jsonl

Check the seal in one click

Your browser downloads the open book and the stamped list, hashes the first N lines of the book named in the list (SHA-256 by WebCrypto, the bytes as stored) and shows both hashes in full — the list’s and its own — with N and the book’s length today, and compares the link of line N with the list’s «last link». Nothing is sent anywhere.

Hash by line count, as stored: head -n N, nothing else. A filter by time drops the answers booked in the stamp’s own second, and jq re-serialises the bytes — either gives another hash.

Who was asked

Each step seals its roster before its first question: who it asks and the spares.

Which list covers which lines of the book

Bytes: the file as stored (UTF-8, no BOM, nothing re-encoded); a line ends with LF; the sha256 of N lines covers lines 1..N, each with its LF; a last line without LF is not counted yet. Check: head -n N daily/council/book.jsonl | shasum -a 256

Two outside clocks on every stamped list

Each answer: when it was sealed
verdict file

RFC 3161: each service signs the exact time. OpenTimestamps: a calendar’s receipt only accepts the hash and states no time of its own; the Bitcoin block fixes it — the list existed no later than a few hours after the block’s header time (a header time may sit up to about 2 h from the real moment: the consensus tolerance).

Chain of lists

Every question sent is sealed before its answer

29 questions of this run are sealed in the chain asks.jsonl, each with a send time earlier than its answer. The text of each is kept in asked/. asks.jsonl

council-ask-parts.json

Which run counts

From 21 Oct: the morning scheduled run counts, the others are for reference.

с 21.10: засчитывается утренний прогон по расписанию, остальные справочные

From session 11 (Nov 2, 2026): within a run, the first well-formed answer line of each seat sealed before the reference counts; the later lines of the same seat are published beside it, outside the count.
