94b of the C-mig2 split (own commit: lone phase-1 test-commit cache gate). The corpus gate now drives two --sep builds (ww / ww_ww) per lib unit and byte-diffs the concatenated per-package .sepwork/*.s. Keying on every per-package .s — the imported lib body (e.g. log.s) and lib/test (test.s), never collapsed to __root.s — preserves the cs!=ww lib-body coverage the gate exists for. Tri-mode (ID/DIVERGE/WWREJECT) per module, import-landed sentinel, and corpus_complete scan all preserved. 43/43 (net=M_ID via #102). Test-only; all 5 binary pins HOLD.
