- sig_image overlay discovery: linear partition (split contiguous code at jr+delay boundaries) + detect_code_end (first run of invalid instrs = the code->data transition; overlay code decodes ~100% valid, data drops to 43-95%). BFS dead-ended — overlays dispatch via function-pointer tables, not jal — so call-graph BFS found ~2 fns; linear partition recovers the whole code prefix - Makefile: sig-overlays: signed 134 overlays -> .run/sig.ov_*.jsonl signs all 134 SCxx 0.4.dec @ 0x80128158 -> .run/sig.ov_*.jsonl (27s) - dup_report --cross: ingest the overlay sigs (sig.ov_* convention) + main/resident; condensed source header (overlay set-sha for reproducibility); cap top-200 per subsection + state totals; compact member sample + #bin column - RESULT (docs/duplicates.cross.md): h_exact 9366 cross-binary groups / 28.5 MB collapsible; h_norm 8957 / 38.3 MB. Top group = a 770-instruction function BYTE-IDENTICAL in all 134 overlays (one match credits the whole fleet) — 'one match unlocks many' quantified; the Phase-12/13 work queue - dedup-check green; committed per-binary digests byte-stable; report deterministic (sorted glob, no Date/random); the EXE<->resident pair still shares nothing (overlay<->overlay dominates)
