# The struct map — the types the fleet's cast sites need (Phase 37 T1)
> **Generated by `tools/type_census.py` at `7a54682a25` (2026-09-30T22:44:05Z); never typed (R75).** Every raw pointer-cast dereference in `src/` was assigned to a base (a parameter, a local, a global by value or by address, an absolute address) and the bases were clustered by EVIDENCE only — the same global symbol, an argument passed to a callee's parameter, an assignment or return, a pointer field read, a shared body's fleet-wide identity — never by a similar offset signature. Each cluster is one type the tree needs. Names are placeholders (`Unkstruct_<addr>`: the lowest global instance's address, else the lowest member function's); fields are placeholders (`unk<HEX>`) until Phase 38 cites evidence.

**19124 types explain 498868 of 502988 dereference sites (99.2 %); 4120 sites have a base the census could not classify; 857 types carry a width conflict.** Merges by evidence: param 38876, assign 16781, arg 10825, field 9896, ret-of 4335, return 1524, assign& 1184, arg& 270.
