Each one refused byte-verified work; each fix is probed, not reasoned:
* built-in redeclaration: a cc1 probe shows two conflicting "memcpy" declarations give
"warning: conflicting types for built-in function" + exit 0, while the same pair on a
non-builtin name errors. Every overlay TU in the fleet declares memcpy twice and compiles
today -> CONFLICTING-EXTERN on a builtin is now WARN.
* driver mismatch: overlays bank via gate_lane -> gate_stage -> harvest_verify, which strips
every typedef the target TU provides; pregate_check modelled gate_main's hoist/strip instead
and reported DUPLICATE-TYPEDEF for exactly the duplicates the real gate removes.
substitute() now takes an optional per-draft transform; pregate passes the overlay one.
* block-scope typedefs: two functions may each declare their own typedef inside their bodies
(that is how a draft stays self-contained for match_one). _typedefs now honours the brace
depth map the caller already computed.
* project scalar aliases: include/common.h's "typedef s32 M2C_UNK;" makes "extern s32 D_x" and
"extern M2C_UNK D_x" the same declaration; _ALIASES now DERIVES those from common.h (R33).
Measured on the 5 leftover slates: 28 drafts, all re-verified MATCH by match_one, went from
"0 kept / phantom FAILs" to main 2 clean, ov_SC04_011 15 clean, ov_SC03_028 1 clean,
ov_SC06_029 4 + 1 named TU edit, ov_SC02_005 2 real TYPEDEF-USED-ABOVE-DEFINITION.
build_wave_atlas: --one-per-gid collapses same-skeleton siblings to one card and defers
them to <out>.siblings.json for the post-bank family_sweep remap (R32 accounting asserted);
--rank total ranks gate groups by DELIVERED mass (card + deferred siblings). Measured on the
wave-T draw: 6,557 drafted ins carrying 12,709 sibling ins behind 69 of 71 gids = 19,266
instructions of potential for 71 agents, vs 9,985 behind 57 under --rank mass. R39 NC: the
flag is byte-inert on a pool whose gids are unique.
gate_main/pregate_check (§192): three defects that made the pre-gate ladder main-only while
reporting "clean" on overlay slates — (1) resolve_conflicts/substitute hardcoded
corpus.stubs('main') -> per-binary _stubs_for(); (2) sym_of returned the keyword `void` for
every `extern void (*D_x[])(...)`, manufacturing 192 phantom CONFLICTING-EXTERNs (NC over
5,526,100 declarations: 189,301 changed verdicts, 0 regressions); (3) `void f()` and
`void f(void)` were normalized together, costing 40 more phantoms — C89's unspecified-
parameter rule is now gate_main.sig_conflict. §192b: the tool refuses when it substituted 0
files, and prints the per-draft [DROP] reasons it used to compute and discard.
Same overlay slate now reports 2 failures, both real (duplicate typedef; memcpy declared two
ways). Cookbook §192/§192b + index regenerated (585 sections).
