The SESSION-25 recipe (grep -v warnings from --stderr-out) applied in-tool across all 4 stages;
gcc-2.7.2 hard errors have no 'error:' prefix so the old tail-truncation drowned them (cost 3
probes). Raw-tail fallback if the filter empties. Verified on a real deliberate CC1 failure.
Task 16 (the integration-recovery pass) T1. The SESSION-15 audit measured the wave bottleneck as
INTEGRATION (~92% of drafts byte-correct, ~27% bank); 36 stranded byte-correct reach-138 drafts are
the fuel. Before building any recovery, measure the REAL blocker per draft.
- tools/rtu_match.py: --stderr-out (atexit flush, covers every sys.exit path) + \n in //@EDIT
replacements (T6 needs a multi-line macro expansion). The inline tail is truncated and these TUs
emit hundreds of benign warnings -- on the first real run it was 100% warnings while the actual
errors sat ~180 lines earlier (the §58 red-herring, one level down).
- tools/blocker_probe.py (NEW, read-only, two oracles R34): static (cdecl.compatible -- never text
equality, which is what made the deleted scanner report u8-vs-unsigned-char as a conflict) and
real cc1 via rtu_match (ONE compile implementation, R33). Leads with the DISAGREEMENT table.
- DELETED .run/diag_plumbing.py (R3 tooling under tools/; R33 net -1 scanner).
- Two build-forced corrections: (1) cdecl.tu_scope runs real cpp, so it already expands instantiated
DEFINE_func_* macros -- the macro scan's job is ATTRIBUTION (tu-text vs shared-header macro body:
different transforms, same T1 tier), byte-checked against engine_core.h:7533 for func_80161374;
(2) blockers STACK and cc1 reveals only the first, so a function's tier is the MAX over blockers.
- Smoke test 3 fns: oracles agree 3/3. src/ untouched (write-set asserted). Not yet population
evidence -- that is T2 / KILL GATE A.
