BONE/SEA S12: load and publish the SEA domain through actual N6

PURPOSE

S12 turns the S11 disk placement into an actual machine-observed N6 loader path. It reads exactly 896 BIOS sectors from LBA 168..1063, publishes 458752 bytes at physical 0x00020000..0x0008ffff, checks IEEE CRC32 across every published byte, installs SEA LDT selector 0x38, validates code/data limits through LSL, restores the N6 supervisor LDT, and continues the existing N6 user-service pipeline.

S12 does not transfer to S10 _start.

FAILURE AND SURGICAL REPAIR

Failed head f4d880b5d44618f8c08ac6b8577d9b3311323185 rebuilt the frozen source graph under crate name bone_sea_s12_source, producing flat SHA256 263a5788fe67b494f96c28b686b9a94efd4505b93dd80fa243cd0f74e37c5e32 instead of the frozen S10 identity.

Current head restores exact crate identity:

- bone_sea_s12_source
+ bone_sea_s10_image

Repair diff: one file, +1 / -1. Loader ASM, expected hash, CRC law, LDT law, adversaries and machine-order judge remained unchanged.

MERGE LAW

S12 is ready for review only against exact parent ef10f68a1d2a0771574882b7e4cad881cebea792 and exact head 56f9697f094fd848b0cf659861f21407b3a9ea75. Any head movement, rebase, retarget or integration requires fresh evidence.

S12 INITIAL IMPLEMENTATION AND MACHINE-GATE LAW

Exact candidate head:

f4d880b5d44618f8c08ac6b8577d9b3311323185

Static branch judge:

• exact parent ef10f68a1d2a0771574882b7e4cad881cebea792;
• seven S12-only files added;
• exact N6 boot/nano/supervisor/user/service sources unchanged;
• exact S10 library/adapter/image/linker inputs unchanged;
• S2 control ledger realized at fixed addresses;
• S10 entry transfer remains forbidden;
• write authority remains disabled;
• GitHub Actions exposes no workflow run for this head.

Required exact-head proof:

Expected native total: 118 / 118 PASS, warnings 0.

The S12 terminal must include actual observed root bytes/hash, SEA CRC32, complete S12 image SHA256, successful 896-sector BIOS publication, code/data LSL read-back, CRC adversary rejection, LDT-limit adversary rejection, N6 pipeline continuation, and temporary cleanup.

Keep PR draft. Do not merge. Do not authorize S13 before exact-head evidence.

S12 EXACT-HASH FAILURE AND SURGICAL REPAIR

FAILED HEAD

f4d880b5d44618f8c08ac6b8577d9b3311323185

OBSERVED

• tracked branch at exact failed head;
• native tests: 118 / 118 PASS;
• inherited S1/S3/S8/S9/S11 proofs: PASS;
• S12 stopped before NASM assembly and before QEMU;
• expected S10 flat SHA256: 835333bb0636540a7af2d3b59b14482bb5157b38c7d3c250148965e0d51991a8;
• observed rebuilt flat SHA256: 263a5788fe67b494f96c28b686b9a94efd4505b93dd80fa243cd0f74e37c5e32.

ROOT CAUSE

S12 compiled the frozen S10 source graph under crate name bone_sea_s12_source. Exact S10/S11 authority compiled that same graph under crate name bone_sea_s10_image. Crate identity participates in Rust/LTO code generation, so the S12 output was structurally valid but not byte-identical to the frozen S10 artifact.

SURGICAL REPAIR

Current head: 56f9697f094fd848b0cf659861f21407b3a9ea75

One file, one line only:

- bone_sea_s12_source
+ bone_sea_s10_image

Diff: +1 / -1 in tools/bone-sea/s12/prove.py.

UNCHANGED

• expected S10 flat hash;
• S10 source/linker inputs;
• N6 loader/root ASM;
• 896-sector publication law;
• CRC32 law;
• SEA LDT/LSL law;
• success trace;
• CRC adversary;
• LDT adversary;
• non-claims.

The failed head makes no S12 loader or runtime claim. Re-run only on exact repaired head. PR remains draft. No merge.
