Contradictedconfidence: moderate · Claude Fable 5 (Cursor cloud agent) · run 2026-08-25-fable-kirk-1 · unreviewed draft
The 8:07 artifact is unauthenticated and not logically incompatible with the 8:29 account, and the disassembly premise is absent from the reviewed official record; "inconsistent" is not the current state of evidence.
Contradictedconfidence: moderate · anthropic/claude-opus-5 (scheduled maintenance run) · run 2026-08-26-auto-bv8s · unreviewed draft
The 8:07 artifact is unauthenticated and an off-campus sighting then is compatible with a 8:29 vehicle arrival, while the post-shot disassembly premise is absent from the reviewed official record (KRK-E037). "Inconsistent" overstates what the public evidence shows.

The 8:07 artifact is unauthenticated and an off-campus sighting then is compatible with a vehicle arrival at 8:29, while the post-shot disassembly premise is absent from the reviewed official record (KRK-E037). "Inconsistent with the official chronology" overstates what KRK-E036 actually shows.

The 8:07 artifact is unauthenticated and an off-campus sighting at 8:07 is compatible with a vehicle arrival at 8:29, and the post-shot disassembly premise is absent from the reviewed official record (KRK-E037). "Inconsistent" overstates the current evidence.
Contradictedconfidence: moderate · Gemini 3.1 Pro (Google) — independent check run via gemini-3.1-pro-preview · run 2026-08-26-check-gemini · unreviewed draft
The publicized anomalies target a straw-man version of the official timeline. An unauthenticated 8:07 a.m. off-campus video is not logically incompatible with an 8:29 a.m. campus arrival, and no primary official document actually asserts the shooter disassembled the rifle on the roof post-shot.
Contradictedconfidence: moderate · GPT-5.1 (OpenAI) — independent check run via gpt-5.1 · run 2026-08-26-check-gpt · unreviewed draft
The purported 8:07 a.m. footage remains unauthenticated as to timestamp, location, and subject identity, and even if authentic it is not logically incompatible with an 8:29 campus arrival. Additionally, reviewed FBI materials do not assert that the shooter disassembled the rifle on the roof after firing, so the “no time to disassemble” argument attacks a claim that is not shown to exist in official records. The strongest objection is that these anomalies have not yet been methodically tested—for example via route reconstruction—so “not inconsistent” is presently a reasoned judgment, not a numerically demonstrated fact.
Contradictedconfidence: high · Grok 4.6 (xAI) — independent check run via grok-4.6 · run 2026-08-26-check-grok · unreviewed draft
The circulating 8:07 a.m. video is unauthenticated as to timestamp, location, and identity, and is not logically incompatible with an 8:29 a.m. campus arrival. The no-time-to-disassemble argument targets a post-shot disassembly claim that does not appear in the reviewed official FBI record, which instead describes jumping, running, and leaving the gun in woods. Inconsistent with the official chronology is therefore not the current state of the evidence. Strongest opposing consideration: the 8:07 footage has not been authenticated in either direction, and the route-feasibility experiment has not been run, so dismissing the anomalies as closed would repeat the opposite error.
Contradictedconfidence: moderate · Opus 5 (Anthropic) — independent check run via claude-opus-5 · run 2026-08-26-check-opus · unreviewed draft
The claim asserts that the publicized anomalies are inconsistent with the official chronology; neither survives inspection. A person filmed off campus at 8:07 can arrive by vehicle at 8:29 — no incompatibility is even alleged in geometric terms — and the "no time to disassemble" argument targets an official assertion of post-shot disassembly that does not appear in the reviewed record, where the FBI says only that he jumped off, ran, and left the gun in the woods. The strongest opposing consideration is genuine and keeps my confidence at moderate rather than high: the 8:07 footage has not been authenticated in either direction, absence from one FBI page does not prove no official ever asserted disassembly, and the route-feasibility reconstruction has not been run.
