Wave P drafted at 97% and then cost a dozen clean rebuilds to bank, and not one of those rebuilds
failed on a matching problem. Banks the whole failure surface:
A. The SEVEN under-reporting holes in gate_main, all the same shape (R32): the checker never read
the destination TU, shared headers, a draft's own definition, lines with trailing comments,
typedef aliases, the build's own error text, or file order. Law: audit a batch-integration tool
for what it DOESN'T look at -- its verdicts can be correct on the inputs it reads and still be
worthless, because the compiler reads more.
B. Typedef handling, with the two wrong strategies that both look right: blanket STRIP (assumes
the surviving definition sits above the insertion point -- src/800.c defines Rec14 at 7336
while stubs wanting it sit at 7272), blanket RENAME (breaks drafts sharing an identical
typedef, because their externs stop agreeing -- my regression, three drafts at once), and the
rescan loop that deletes the definition it just renamed. The survivor is body-aware +
position-aware in a single pass over a snapshot.
C. The remaining limit: conflict detection compares spelled type NAMES, so three drafts each
defining their own Slot54 with different layouts all declare func_80032A74(Slot54*) and compare
equal. Comparing struct LAYOUTS is the real fix.
D. The measured cost shape -- drafting cheap and solved, integration expensive -- and therefore the
next lever: a STATIC pre-gate check over the substituted text, no make at all. Plus the R39
lesson that negative controls apply to the tool you are FIXING, not just the one you ship.
