The 2nd straggler class (cont.4 wave-2): cross-overlay loose-typing COMPILE errors (not just
the -O0 byte-mismatch class). The -O0 exclusion alone was insufficient. Refactor the propagation
into a drop-straggler retry loop: extract apply_plan(subplan, restrict=); on a byte-gate failure,
isolate the culprit(s) for the failing overlay (per-fn trial), drop them (kept x1), retry the
survivors. Handles BOTH straggler classes failing ANY overlay; plan strictly shrinks (terminates);
byte-gate stays sole arbiter (a dropped fn never banks where it isn't byte-identical).
Validated end-to-end: wave-2 --auto-from auto-dropped 2 loose-typing stragglers + propagated 3
clean x134 (commit:0271); fleet 62.70 -> 62.82%. Future _a waves now auto-realize x134, no manual probe.
The cont.4 root-cause fixes so future _a waves auto-realize ×134:
- dedup_propagate --auto-from now excludes *_o0.c (-O0) defs: -O0 codegen embeds per-overlay
%lo data, so masked h_exact falsely reports reach-134 (§18/§20). One such straggler
(func_8013C360) reverted 10 clean ×134 matches under the all-or-nothing batch gate (cont.4).
Detected via find_site on the -O0 split file; --addr still forces them. (6 fns excluded.)
- gate_stage: capture dedup_propagate's exit; on a real byte-gate revert (not the benign
'nothing to propagate' no-op) write .run/auto/last_propagate_error.log + add prop_error to
the summary + warn. A swallowed revert previously hid the gain silently.
- dedup_propagate split-aware: overlay_files() handles ov_SC01_077's Phase-19 split (main + _a/_o0);
source-find scans all, member-loop edits the right file, structural-check spans all. Single-file
overlays unchanged (default path). Validated: source-find (--check-only 134 members) + fail-closed revert.
- cast_call_sites --src-file: canonicalize callee decls against the file the draft lands in (cross-file
loose typing — a callee declared differently in main vs _a.c). Default = main, unchanged.
- FINDING (cookbook §24): the fresh reach-134 fuel (66+ fns) is in ov_SC01_077_a.c (a tooling gap, not
difficulty); bodies are matchable (func_8012C098 cast-banked) BUT matching/propagation hits the same
§16/§20 loose-typing wall (func_8012C098 cross-overlay def-conflict -> x1; func_8012F274 within-_a
RotTransSV multi-sig). x134 yield uncertain -> a small measurement wave is the next probe.
- no net banks this turn; fleet 62.31% unchanged; ov_SC01_077 verified d19c9580 (R22). sig_unify reverted.
- tools/sig_unify.py (NEW): unifies a draft's FULL signature set to the banked-canonical
decls — both callee externs AND the draft's OWN definition signature (return + param
types, body param-names preserved). Recovery for the standalone-MATCH residual: a probe
found 30/30 sampled failures were type conflicts, 0 false-positives. Gated 191 -> 32 verified.
- tools/dedup_propagate.py find_site FIX: the inline-def detector required the opening brace
ON THE SAME LINE as the signature, silently dropping every next-line-brace def from
propagation (sig_unify/permuter outputs + ~stragglers all session). Now accepts brace on
the same OR next line -> unlocked a 61-function propagation backlog.
- propagated 61 fns fleet-wide (incl. 32 sig-unify + the permuter win func_801508F8 +
earlier-dropped next-line-brace matches), all 134 byte-identical; dedup-check 1394/0
- R22 CLEAN fleet rebuild: 136/136 byte-identical. REAL 177501 -> 185646. Zero agent tokens.
- gen_harvest_targets.py: now also resolves canonical DATA-symbol declarations per target
(scan the .s for D_XXXX refs -> `extern <type> D_XXXX;` from banked code) in addition to
callee function sigs — the §14c(c) fix at the source, so agents declare both functions and
data correctly and avoid the dominant remaining conflict class.
- v2 harvest (callee+data-sig-aware) on the 591 small still-stub call-heavy fns + a gap-fill
agent for 6 targets dropped by a connection-closed-mid-response failure (the retry-wave
misses truncated-non-null results). Gate: 306 verified (ov_SC01_077 1554 -> 1248 stubs).
- dedup_propagate.py: skip any struct/union-touching body — agents named structs with colliding
generic names (`struct S`/`struct vec`) inline, so two macros' types redefine/conflict when
instantiated in one overlay (ov_SC01_000 abort). 34 skip; struct-using shared fns stay banked
in 077 (shared-types-header follow-up).
- 281 functions propagated fleet-wide (134 overlays each, every overlay byte-gated); dedup
795 -> 1076 groups, dedup_integrate --check 1076 validated / 0 failed.
- fleet REAL substantive 105,764 -> 143,322; byte-identical 31.22% -> 42.14%.
- R22 clean rebuild: 136/136 byte-identical, 0 extract failures.
- cookbook §12: gap-fill is now a MANDATORY post-step for every multi-agent run (reconcile
produced-vs-expected: missing + truncated drafts) before gating.
- 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
