Audit trail
Two of the eight turn files are marked INVALIDATED. The federation got things badly enough wrong that those turns had to be re-run from scratch. The original files are still on disk — that's the rule. The point of an audit trail isn't to hide the failures; it's to make them readable.
Turn 4 — Wrong election framing
The original turn 4 modeled the November 2026 election as a presidential election. It isn't. It's a midterm — congressional only. That meant the original brought in a whole pile of irrelevant mechanics: Electoral College dual slates, January 6 elector certification, January 20 inauguration, dual presidential inauguration. None of that applies. The US president stays in office through January 2029 regardless of what happens at the midterms. The only ways out are impeachment plus a 67-vote Senate conviction, the 25th Amendment, or resignation. The turn got re-run.
Original: worldstate/turns/0004-INVALIDATED-presidential-framing-error.yaml.
Re-run: worldstate/turns/0004.yaml.
Turn 5 — Built on the turn 4 error
The original turn 5 was built on the bad turn 4. It inherited the same wrong election framing and ran the consequences forward. When the turn 4 error was caught, turn 5 had to be invalidated and re-run too — you can't fix a turn by patching, because the downstream consequences have already been routed to the other specialists.
Original: worldstate/turns/0005-INVALIDATED-built-on-T4-error.yaml.
Re-run: worldstate/turns/0005.yaml.
Why these stay in the record
The federation has rules about being legible — every adjudication has to include a note about what a different umpire might have done, the contrarian's case has to go into the official record, and bias warnings carry forward turn over turn. The invalidated files are the same discipline at a higher level: the federation can get the frame wrong, not just the numbers. When that happens, the failure stays visible so the next reader can see it. The two invalidated turns are the only ones in the series.
A non-error file worth flagging
There's also a non-error artifact in the turn log:
worldstate/turns/0000b-revision.yaml. After the first turn 0
was written, the analyst expanded the starting conditions substantially —
added detail about how the executive compromise actually works, how the
Israeli and Russian leverage diverge, and the DHS-paramilitary
structure. The rule is no retroactive edits to original turn files, so
the expansion sits alongside the original instead of replacing it.
Process files worth reading directly
worldstate/turns/0006-mind-changing-observations.md— what made the orchestrator update its priors during turn 6.worldstate/turns/0006-modal-hold-review.md— the first modal-hold review and the variables it flagged for retirement.worldstate/turns/0007-mind-changing-observations.md— same idea, for turn 7.
