MEASUREMENT CORRECTED THE PLAN. The checkpoint called for a "per-camp field-access reconcile";
measuring the camps refutes that: Vec8 = {s32 w[8]} (32B) in 180 files AND {s16 unk0..} (8B) in
139 files; MATRIX 48B/32B/32B; Buf 16B / 0x20+ / DrawEnv. These are DIFFERENT types sharing an
identifier across TUs of the same overlay — reconciling to a canonical layout MERGES them, the
same failure that broke 103 binaries on Prim. The right op is UNIQUIFY: rename the non-majority
camp (byte-neutral — a type name emits no code; TU-local by construction), which makes every camp
single-def and liftable by the existing lift_types rules.
- NEW tools/uniquify_type.py: deterministic camp ordering (file-count desc, then normalized text,
so re-runs assign the same suffixes); majority keeps the name, camp n -> <T>_c<n>; rewrites ONLY
files that DEFINE that camp (a file that merely USES the name gets it elsewhere and is untouched);
\bT\b word boundaries so `Buf` never matches `Buf80153978`.
- VALIDATED on Buf (578/6/1 files): 11 identifiers across 7 files -> 3 camps LIFTABLE -> lifted
(585 local copies stripped) -> R22 140/140 -> blocked core queue 13 -> 11 (0x8012ea90, 0x801749c8
freed). Propagated 0x8012EA90 ×138; 0x801749C8 dropped (straggler in ov_SC07_006).
- YIELD, HONESTLY (P9): ZERO new matched functions. fn-count 88.61% / instr 79.3% / stubs 40281 all
UNCHANGED; dedup 1867->1868, C1 +138. 0x8012EA90's members were ALREADY matched in all 138
overlays — the propagation consolidated duplication into one shared macro (DRY), not coverage.
The value is the PROVEN RECIPE + the queue moving 13->11, not the numbers.
- dedup_propagate (R32): the skip line printed a COUNT and no names, and aggregated three unrelated
causes into n_local — a body skipped merely for a `//` comment (macro-unsafe, 1-line fix) read
identically to one genuinely using an overlay-local type. Now named and split by cause.
- cookbook §64a (uniquify-vs-reconcile + the validated recipe + remaining camps by cost).
