Canonical-copy instruction experiment — shortened at user's request

Original three-pair protocol remains in protocol.json. Only repeat1 completed; the user stopped additional repetitions as unnecessary. Repeat2 was interrupted, and its owned profiling descendants were explicitly terminated. Partial repeat2 artifacts are preserved but excluded. The original three-pair acceptance gate was not completed and must not be called passed.

Repeat1 whole-process N3−N1 normalization:

Case baseline Ir candidate Ir reduction
multiply2048² 5,315,180 5,310,838.5 0.0817%
GEMM1024 523,494,572.5 523,494,508.5 0.000012%
LM3_12d path mean 950,488,172 837,405,324.5 11.8973%

These are provisional instruction results, not native speedups. Baseline is 2fd8163/strided17e05ff; candidate636cd499/strided78d5190; shared compiler/provider and explicit1T as documented by the protocol. Fixtures and baseline provenance are also recorded in sibling eager-read-forwarding. Follow-up native results in ../native-1t/ are inconclusive due observed L3 interference.

The raw directory additionally preserves CPU/AD integration logs, the initial BLAS UI-link failure, the successful linked run and Docker's final exitCode0 event after the outer client's timeout. The test linker is included. No UI snapshots were changed; the worktree manifest was restored after local patches.
