I SE CLASSICAL IJCCRL CUP DERIVED STOCKFISH 280326 — Provisional Regular Phase Update
This block reflects the current published cut of the regular phase. The published segment is structurally consistent under IJCCRL regular-phase rules, and the standings below are therefore valid as a provisional live table. However, the phase remains open, so this state should still be presented as a provisional update, not yet as a final Regular Phase Audit PASS for the full event.
Snapshot state
Passed audit controls in the current published cut
- PASSComplete PGN with final results for all 178 published games; no unfinished published game detected.
- PASSDeterministic pairing integrity verified for the published segment: opening indexes run continuously from 1 to 178, with 89 two-game mirrored units already closed.
- PASSNo duplicate games detected under D1/D2 control in the current published pack.
- PASSRound-robin colour balance verified: 14 engines stand at 11W/11B, while Artemis and DarkSeid stand at 12W/12B.
- PASSTermination and TB evidence are recorded in the published material. The pack includes 174 games with positive TB signal; proxy-fatal incidents are explicitly preserved, not hidden.
- NoteThe fixed-duel exact side-balance rule is not the governing criterion here. This stage is a regular-phase round robin, not a semifinal or final duel.
Forensic status of the phase
The published regular-phase cut is auditable and internally consistent. It can therefore be published with live standings, a provisional rating list, and the audit controls already passed. The final Regular Phase Audit PASS for the whole phase remains deferred until the remaining schedule is closed.
