# Rename map (old -> new)

Mechanical, semantics-preserving. Qualified cross-module uses renamed too

### SYMTAB stage-2 amendments (v1.00 hardware proofs, Oct 2026)
* `COMPILER.dword27` -> `allocHook: PROCEDURE(ADDRESS, ADDRESS)` (appended
  last in COMPILER.DEF, no slot shifts). PASS1 stores a hook address
  (`store COMPILER.dword27`); SYMTAB calls it (`load dword27 +
  extern_proc_call`, byte-exact shape proven). Was misread as
  `allocateSignature` (a type symbol) — wrong target.
* `ERRORS.word2` = `savedEditPos` ONLY (edit-position save in DoError).
  `ERRORS.word5` = last-error-code (private `errorNumber`, stored by
  PrintOverlayMessage @0677, printed by FindFileOnDrives). TryCompile's
  `saveErr` was fiction: 0b4c compares `savedEditPos > savePos` (edit
  happened -> rollback+retry, else HALT). RENAME-MAP `global5->errorNumber`
  refers to this word5 (correct as-is).
* `SYMTAB.word8` = `scopeChain`, `word9` = `currentScope`,
  `SYMTAB.proc7` = `RestoreAfterEdit` (all proven from ERRORS.MCD call sites).
* Heap-budget abbreviations (MOD-private impl vars only; DEF/external names
  untouched; comments keep long forms): symHeapBase->symHeap,
  scopeHeapBase->scpHeap, strHeapBase->strHeap, exportHead->expHead,
  stageNameTotal->namTotal, savedSymInfo->savSym, savedStrInfo->savStr,
  stageFlag->stgFlag, stageSpare11->spare11, stageSpare26->spare26,
  checksumTemp->chkTemp.
* v1.00 bans (all probe-proven): indexing/dereferencing transfer results
  (`Words(x)^[i]`, `P(x)^.f`) -> view-typed params (PutAttr/AllocSym/
  EnterIdent `scope`/`src` retyped to Words, zero-cost transfers at call
  sites) or temps; CARDINAL compares for T1-vs-RecordPtr; `curSym = 0`
  for `eq0`; `keyHash` DEF is `(ADDRESS, CHAR)` (original's
  `(Identifier, CHAR)` unsatisfiable under retail nominal checks; U-probes
  prove identical pushes; `CHR(ORD())`/`ORD()`/`CHR()` are zero-cost).
* OOM often masks type errors (VAR-mismatch, `Allocate(ADR(..))` OOM instead
  of erroring) — isolate suspects in fresh-heap ZZ probes, never trust the
  cliff position alone. ELSIF-nesting pins condition heap; tail-positioned
  chains flattened to sequential IF+RETURN (EnterIdent).

## SCANNER interface abbreviations (v1.00 name-table budget, proven on hardware)
ChangeFileExtension->ChangeExt, ExpectStringLiteral->ExpectStr,

TestSymbolRange40/13->TestRange40/13, CopyStringToHeap->CopyString,
EnterModuleSymbol->EnterModSym, ExpectIdentKind->ExpectKind,

longrealValue->lrealVal, PushWithScope->PushWith, OpenSourceFile->OpenSource,
NeedIdentifier->NeedIdent, TestSymbolInSet->TestSet, CheckStackMark->CheckStack.
DEF params single letters (must match MOD exactly). DEF imports trimmed to
interface-used (SYSTEM/Compiler/Files/SymTab). Same discipline required for
all future DEFs.
