The waves flagged ~40 candidate laws. Five were byte-probed, generalizable and actionable enough to bank; they were deduped by hand against the file (no skeptic-agent pass this time, so each says what it sharpens and why that section is insufficient): - §163a decl-conflict severity is SCOPE-DEPENDENT — hard error if either decl is at file scope, warning only if BOTH are at block scope. §8d proves the phenomenon on D_801812A4 but never states the rule or its LEVER half: block scope is a deliberate conflict SOLVENT, so a struct-typed draft can be banked into a scalar-typed TU by moving the typedef AND the extern into the block. - §163b the switch-index parameter-WIDTH oracle: sll/sra straddling the minval subtract is a 2-insn signature of a short parameter. Read the extension, not just the bound. - §163c case_values_threshold is 5 — an empty `case k:` glued to default can be the only thing that emits a table at all; jtbl[k]==default label is the tell. - §163d cse deletes a reg-reg copy by rewriting the PREVIOUS insn's SET_DEST (cse.c:7440-7477). This is §162j's symptom in a DIFFERENT PASS and needs a different lever; the residual it explains had been declared "unsteerable, 30 variants all >=17" and fell to source-shape edits alone, no pins. - §163e the frame is a PSEUDO-NUMBER oracle (reload1.c:658 alter_reg in NUMBER order); dead-local slot order is not declaration order, and a BLKmode local is 8-aligned while a scalar s32 is not. Sharpens §162i, which gets the pad's SIZE right and its PLACEMENT wrong. §163z catalogues the ~35 unvetted claims by function so a future harvest can go straight to them, explicitly marked "one agent's reconstruction until re-measured" (R14). cookbook_index.py: 497 sections.
