Route the 16 routable bare-primsize GUARD sites (is-primitive / struct-vs-prim dispatch) through the #101 aliasprimsize SSoT helper. Byte-NEUTRAL by construction: an alias-narrow name is already neutralized downstream by the same arm, so routing emits no new asm (the empty-flip-set ken oracled). Shape-A exclude-prim-early (3): cgenutil sretretsize / structparamsize / structfloatclass — `primsize>0 return` then structlookup→nil returns the same value; route returns it early, same. Shape-B prim-guard-then-structlookup (13): cgenutil 4604/4650 + cgenexpr 4136/10244 + the 9-site CALL/assign cluster — primsize==0 →structlookup→nil→fall to normal; route skips the block→same normal. Install the peellint bare-primsize FINALE (B7 lint-fuse contract): tools/peellint now rejects any bare primsize() in the ww stage outside the annotated whitelist. Evasion-hardened per the B7 lesson — a character scan (comments + string/char literals stripped first) and a LEFT+RIGHT word-bounded match of the bare `primsize` TOKEN (not just `primsize(`), so the aliasprimsize() wrapper is never a hit and every compiling spelling reds: the call primsize(nm), the paren-wrap (primsize)(nm), the function-value bind `let p = primsize`, and any line-split. ww-only (the C stage dealiases via type_chase_named, no primsize symbol). Two independent exemption windows (peel-ok vs primsize-ok) so neither rule blinds the other. Runs as a make-test dep. Whitelist the 6 designed exemptions with primsize-ok WHY-annotations: machinery — aliasprimsize body (SSoT chase) | typenodeprimresolved + exprprimresolved (#11/#33 prim-resolver chasers) | cgcast leaf-loop + cgenexpr #11 deref-store (own ps==0 fallback; route would regress #11) | the primsize oracle/definition itself (nothing below to chase). structural — elemsizeof x2 + paramfieldsize (chase lives in the -c twin elemsizeofc; threading c is the dormant #110). Empty-flip-set proof: zero C bytes; cstage binaries bit-identical; bootstrap byte-id 990-997 + 950 all green (w6c == w6c_ww on the full selfhost, self-rebuild identical); combined.ww (w6c + wwdump) regen idempotent; sizelint 0; peellint 0 (raw-peel AND bare-primsize over the whole tree = the close-by-construction proof, zero unwhitelisted survivors). Tests: 944_peellint_gate +14 rows (bare / space-before-paren / name-at-EOL split / string-blind opener / paren-wrap / fn-value-bind RED; aliasprimsize wrapper + primsize-ok annotated GREEN; corrupt annotation RED; independent peel/primsize windows; C-file out-of-scope). Closes the #101 primsize-alias family by construction. #109.
