Task #5 step 1 (plan §7a.8/§7a.9). The C/C++ function-pointer dispatch synthesizer swept every file's text four times (typedefs, registrations, propagation, dispatch); at kernel scale the all-or-nothing source cache declines, so that was 4.4 read+strips per file — 78s of the ~230s pass. Now ONE extraction sweep reads+strips each file once and collects typedef names, struct-node field declarations (structurally parsed, fn-pointer classification deferred until the typedef sets are complete), resolved includes, an alias-shaped-macro name set, and per-file survival filters (init type tokens, array element types, inline-struct summaries, field-assign pairs, dispatch fields/array names — interned, a few MB on linux). The linking stages then replay the ORIGINAL pass bodies verbatim: struct layouts register in kind-scan order (same-name precedence is order-sensitive), and registration/propagation/dispatch run only for files their filter proves can have side effects, lazily re-stripping just those. Filters only over-approximate (full-file no-skip scans ⊇ the real passes' jump-cursor scans), and a filtered-out file is one where every match fails the pass's own gates before any side effect — parity by construction. Macro tables stay lazy: a sizing probe found 6.1M #define lines on linux (amdgpu register headers), ruling out retention. Measured (8c cg1212, quiet host, fresh kernel init): cFnPtr pass 230s → 179s (−22%); strips 283.5k → 132.4k (4.44 → 2.08/file, 78 → 46.6s); dispatch stage 95 → 18.5s; callback-synthesis phase 250 → 199.9s. Standalone probe on the live DB: 139 → 122s. Byte-parity gates, all green: probe-hash identical on the live kernel DB (279,335 edge rows both builds); git/redis/vim/SameBoy full dumps byte-identical old-vs-new (macro tables, commands.def, #ifdef include-units, inline structs, bare arrays exercised); kernel-parity 0-diffs on git/redis/fmt/protobuf, deferral unchanged; linux counts exact 2,049,153/6,413,518 and dump sha 6dd1185b… reproduced (10,446,478 lines); full suite green ×2 (152 files / 2563 tests). Step 2 (native per-file extractor) now has its boundary: the extraction sweep, raw text in → records out. Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
