- tools/dedup_propagate.py: lift a matched body -> DEFINE_func_<ADDR>() macro in
src/shared/engine_core.h -> instantiate in place at every onboarded overlay sharing
that h_exact -> snapshot + per-overlay byte-gate (fail-closed revert) -> register in
config/dedup.us.yaml. Keyed by addr-int (sig lowercase vs splat func_%08X).
- proof: 4 medium funcs propagated across all 16 onboarded overlays; clean check-all
18/18 byte-identical; dedup_integrate 8 validated/0 failed; idempotent; negative test
(corrupt shared body) -> make check FAILS then restores
- Makefile: header-dependency tracking (cpp -MMD -MP + -include ) so editing a
shared header recompiles dependents — closes a stale-build/false-pass gap the negative
test exposed; output-neutral (R22 clean 18/18)
- structural self-check: a leftover INCLUDE_ASM stub is byte-identical, so the byte-gate
can't catch under-application -> assert DEFINE present + stub gone
- FINDING: 577 of ov_SC01_077's 785 matches are h_exact across all 134 overlays
(2.19 MB collapsible, already matched) -> T5 = bulk-propagate these + harvest the rest
- cookbook §14 (the propagation runbook + gotchas), SETUP tool inventory
- ghidra/ churn NOT staged (R23); build/asm/.run gitignored
