phase-36: S104 opens — Drew's dispositions of S103's four questions, read against sotn-decomp's tree (0 pins, !FAKE do-while kept as C, one GTE header with project-local macros); milestone amended: unclosed sites stay marked and go to the structs phase

+  shape right without pins. 4, huuh? a new phase for types?. for all 4 questions, search the sotn decomp"* → read from sotn-decomp's
+  tree (R106; shallow clone `tools/reference/sotn-decomp` @ `6cbc55a`, 2026-09-11, ignored; X2 — data): **its PSX C carries 0
+  `register … asm` pins and 0 asm statements** (all 31 asm statements in `src/` are Saturn/PSP or data directives) across 2,987 C
+  files — **it keeps 3,101 `INCLUDE_ASM` stubs instead**; its fakes are ordinary C marked by `docs/STYLE.md`'s rule *"A fake should
+  be commented with an `// !FAKE:` above or to the side of the code"* — `do { … } while (0)` (e.g. `st/nz0/gaibon.c:563` "do-while
+  needed on PSX but not PSP", `libc/sprintf.c:129` `} while (0); // FAKE`, `dra/5087C.c:476` "temp variables, meaningless
+  self-assigns, and do-while(0)"), `if (prim && prim) { // !FAKE`, `volatile u32 pad; // !FAKE:`; its GTE ops are ONE header

+  of them three-op load forms (`gte_SetRGBfifo`: three `lwc2`; `gte_SetIR123`/`gte_SetMAC123`/`gte_SetRii`: three `mtc2`/`ctc2`, no
+  clobber). **Dispositions:** (a) `do { } while (0)` and the dead-initialiser cousin STAY as ordinary C for now, marked `// !FAKE:`
+  per sotn's rule, not a census lever class; revisit later (Drew). (b) GTE deferred — T5 as planned, and when it runs, sotn is the
+  precedent that a project-local macro (a respelled `gte_stORGB`, a three-op load) belongs in the one GTE header. (c) **Every site
+  is reducible to C** (Drew: the 1998 code was C, and sotn shows a PSX decomp with zero pins); a site T7 cannot close now stays a
+  MARKED minimum-lever site, counted, and is carried to the **structs phase** (the missing piece is likely the struct shape) — the
+  phase's milestone "0 pins, 0 asm" is amended to "every surviving site marked, counted, and named for the structs phase" (P5d, on
+  Drew's word). (d) "the types phase" in S102–S103's checkpoints is NOT a new phase — it is the **structs phase**, the third in
+  Drew's Gen3 order (dedup → pins → structs → names; R95's canonical type layer is its core); the signature changes
+  (`func_8017FC5C`, `func_80180200`, `func_80185578`, `func_80157D20`, `func_80168828`) go there with their ready patches.
 - **S98 (2026-09-09), Drew, mid-T3:** *"dont start ultra code wave for reshaping without my direct approval."* → **T7's reshaping waves (Ultracode) start ONLY on Drew's direct approval in the session that would run them** — the R27 toggle is necessary, not sufficient; the T6 recipe/permuter rungs and the mechanical campaign are not waves and proceed under P3.
