TAGGED SUMMARY — compiler outline v1 [tag: compiler-outline-v1]

One-page snapshot. Details in 00-overview.md .. 70-rename-plan.md.

What

Turbo Modula-2 compiler decompiles and runs, but decompiled/COMPILER/ identifiers are procN/globalN. This folder restores the map without touching upstream sources (upstream dirs are git-ignored).

Map

• Resident: Compiler (symbol descriptor + predefs) + Scanner (128B window, GetSym/Accept/Expect) + SymTab (scopes, .SYM import/export) + Errors (ERRMSGS.OVR, Edit/Quit, rollback) + CodeGen (MCode emit, 2KB window, OpenFix/CloseFix).
• Transient (Loader.Call): COMPILE = Pass1 (decls/types/WriteSym) + Statemen (STMT dispatch 121..130, FOR/CASE/IF/...) + Express (EXPRES, designators, const-fold, std-proc expand) + GENZ80 (native, later).
• Drivers: C.MOD M2C, Scanner.Compile, ComLine.

Key renames (proposed, ~ = to confirm by recompile)
