R12 SD-CST Complete Physical Fresh-Board v1.3 Receipt

Status: admitted and sealed before training-seed draw, model fitting, or scored access.

Custody ordering

1. Scientific source commit eed66757c47e126b6566ee269bc73b0c0cef4fab was pushed before randomness.
2. Raw 64-bit board beacon 18144246429379773690 was drawn afterward.
3. The beacon was reduced modulo 2^63 to board seed 8920874392524997882.
4. The exact committed source generated and audited the board.
5. No training seed exists at this receipt point.

Board certificate

Board report SHA-256: fd487cdf7c30cf945ace152e389aaf5c354b8b6a55555c2acc6f046e8ed00b24

The report identifies schema r12_sd_cst_complete_physical_fresh_board_report_v1_3, protocol r12_sd_cst_complete_physical_fresh_v1_3, exact source commit, and exact board seed. All 17 admission gates pass. They include independent semantic/oracle agreement, exactly nine bounded records and one HALT, production-parser acceptance over all 52,096 rows, renderer parity, globally unique split/prior- disjoint names, zero exact/13-gram/name/operation-sequence leakage, expected counts, sealed confirmation, and zero scored access.

Confirmation is mode 0600. Development/confirmation access is 0/0; no board-local access directory exists. A complete second build from the same source, seed, and prior inputs is byte-identical for report, training, development, and confirmation files.

Frozen neural contract

Treatment and the matched family-deranged arm each train 102 tensor names / 12,152,855 parameters for 3,000 updates. Complete deployed size remains 192,129,179 with 7,870,821 parameters of strict-200M headroom. Every setting, gate, threshold, control, and claim boundary is frozen in R12_SD_CST_COMPLETE_PHYSICAL_FRESH_V1_3_PREREG.md.

Training-seed receipt

Board receipt commit fc9ee4c4d110c14662705a70f70a70d07a9fe68f was pushed before raw training beacon 8446904969546017898. The value is below 2^63 and becomes the sole training seed unchanged. No architecture, board, arm, optimizer, update, gate, threshold, assessor, or claim-boundary setting changes. No GPU job, output directory, development access, or confirmation access exists at this receipt point.

The next allowed action is to commit/push this seed receipt, transport and hash- verify exact source/board/parent bytes, pass Slurm test-only admission, and submit one score-bearing job. No development or confirmation bytes may be opened before both matched endpoints and the immutable gate config exist.
