E04-S07 Claim

Intended change

Finish the pass-3 address path: count-mode sizing with zero mismatch, final section and method addresses in the MAP, unresolved-reference diagnostics, deterministic PRGs, and a real source file running in x128.

File area

src/compiler/flow.s, emit.s, sizing.s, parser.s, diagnostics.s
src/compiler/output.s, src/common/formats.inc, diagcat.inc
tests/compiler/counter.n8, tests/compiler/counter-test.s
tests/runtime/class-test.s, tests/parser/unresolved.n8
scripts/build-*.ps1, scripts/verify-*.ps1
docs/decisions.md, docs/architecture.md, docs/memory-map.md, docs/diagnostics.md

Acceptance evidence

sizing.s measures each routine in count mode so pass 2 and pass 3 produce identical lengths and label offsets; sz_mismatch is 0.
Pass 3 patches absolute JMP/JSR label fixups; relative branches stay offset-based. counter.n8 runs from CODE 1C4F with total = 15.
MAP ENTRY and SECTION records carry final addresses; class records and METHOD entry addresses are emitted and checked by the class fixture.
Forward references resolve; tests/parser/unresolved.n8 reports exactly one SEM_UNKNOWN_NAME (E61) and no bad-operand follow-up.
Recompiling the same source is byte-identical: COUNTER.PRG and COUNTB.PRG compare equal.
E202 overwrite refusal still holds; the output suite leaves COLLIDE.PRG/COLLIDE.MAP unchanged and leaves no output after abort.
counter.n8 compiles from source and runs in x128 with total = 15.

Work log

flow.s now resolves absolute JMP/JSR operands against fl_code_base; ordinary fixtures keep the default cg_code base.
sizing.s computes PRG_ENTRY_ADDR + bytes-before-CODE and installs it for the emitting pass. sz_capture/sz_verify compare code length, entry offset, per-routine sizes, and all label offsets.
emit.s records routine sizes in em_routine_sizes and selects count mode through em_count. parse_file clears count mode, diagnostic suppression, and any base request; parse_file_sized opts into the counted path.
diag_suppress prevents duplicate diagnostics during the emitting pass. RES_SIZE_MISMATCH (E228) reports a count/emit disagreement.
output.s/formats.inc add bounded METHOD name address MAP records after class records. The class fixture checks METHOD DESTROY and METHOD STUB.
Added the one-reference unresolved.n8 parser fixture and the matching SEM_UNKNOWN_NAME expectation.

Completion

Tests run: statements, calls, member, control, scalar, hello, parser, counter, output; class test separately. All PASS.
Parser: 42 fixtures, including unresolved.n8 with exactly one diagnostic.
Counter: 175 code bytes; sz_mismatch = 0; MAP ENTRY 1C0D, START 1C0D 0042, CODE 1C4F 00AF; COUNTER.PRG and COUNTB.PRG byte-identical; generated PRG reports total = 15.
Class MAP: CLASS EMPTY, CLASS BOX, METHOD DESTROY 2A56, METHOD STUB 2A57; all descriptor/MAP flags pass.
Remaining risks: the code buffer remains 255 bytes and em_entry remains an offset; general runtime startup and frame sizing remain separate work.
