Add the generated PRG and MAP writer (E04-S01). 

Emit a BASIC-stub PRG with ordered sections and a MAP entry/section table,
refuse existing output names, and scratch partial files on failure. Include
a runnable startup that reports through the test mailbox.

The generated PRG begins with load address `$1C01`, the 12-byte BASIC 7 stub
`10 SYS 7181`, and machine entry `$1C0D`. Sections are emitted in ascending
address order; a gap before a section is filled with zero bytes. The entry

initializes the test mailbox, reports producer `$03` and PASS, and returns to
BASIC. The test fixture keeps its sections below `$4000`, where BASIC's mapping

Authoritative source: `cfg/compiler.cfg`. This document explains it.

The generated-program memory map is **not** frozen here. It belongs to E04-S01
and E04-S02, which must reuse the test mailbox below.
E04-S01 defines the generated PRG/MAP container below; the higher
generated-program map (banking, heap, software stack) still belongs to E04-S02.

existing `NAME.PRG`/`NAME.MAP` and scratches outputs it created on failure.
Test sections stay below `$4000` until E04-S02 freezes the runtime mapping.

# E04-S01 Claim

## Intended change

Add the generated-program container and writer. `src/compiler/output.s` accepts
a source base name, writes a PRG with a valid load-address header and ordered
sections, records each section's start/size plus the entry point in a MAP file,
and emits the fixed BASIC 7 stub and startup path from
`src/runtime/startup.s`. The generated program initializes the test mailbox,
reports pass, and returns cleanly to BASIC.

An existing `NAME.PRG` or `NAME.MAP` is refused with the new disk diagnostic
E202 instead of being overwritten. Outputs created by the current run are
scratched if emission fails or the caller aborts, so no partial final file is
left behind.

## File area

- `src/compiler/output.s` (new), `src/runtime/startup.s` (new)
- `src/common/formats.inc` (new), `src/common/diagcat.inc`, `docs/diagnostics.md`
- `tests/codegen/output-test.s`
- `scripts/build-output-test.ps1`, `scripts/verify-output-test.ps1`
- `docs/decisions.md`, `docs/architecture.md`, `docs/memory-map.md`
- `planning/claims/E04-S01.md`
- generated files under `build/`

## Acceptance evidence

- [x] Writes a valid load-address header and deterministic sections: the
generated `generate.prg` is 133 bytes, starts with `01 1C`, contains the
verified 12-byte `10 SYS 7181` stub at `$1C01`, 74 startup bytes at `$1C0D`,
zero padding through `$1C7F`, and `DE AD BE EF` at `$1C80`.
- [x] Emits a runnable startup path and clean termination: the extracted PRG
autostarts in x128, writes producer `$03`, status `$A5`, code 0, empty data,
and returns to BASIC.
- [x] Refuses/handles output-name collision according to the approved policy:
the pre-existing `collide.prg`/`collide.map` fixtures cause
`OUT_ERR_EXISTS`; both files remain byte-for-byte unchanged because nothing
is opened before the check.
- [x] Removes or marks partial output after any failure: the `order.prg`
section-order failure and the `abort.prg` partial-section run both call
`out_abort`; neither PRG nor MAP exists afterwards.
- [x] MAP records section start, size, and entry point: `generate.map` is the
exact CR-terminated sequence `NOVA128 MAP 1`, `ENTRY 1C0D`,
`SECTION STUB 1C01 000C`, `SECTION START 1C0D 004A`,
`SECTION PAD 1C80 0004`.

## Coordination notes

- E01-S05 and E02-S04 are `done`; no other claim overlapped this area.
- D128 records the provisional container and refusal policy. E04-S02 still
owns the higher generated-program map (banking, heap, software stack);
this story's fixture keeps sections below `$4000` where BASIC's mapping
exposes RAM.
- `output.s` returns `OUT_ERR_EXISTS`; E202 is in the stable catalog for the
compiler shell (a later story) to report. No shell integration was invented
here.
- Production and abort paths use the existing `diskio.s` wrappers; no module
except `mmu.s` touches the MMU.

## Work log

- Built the writer around a compact section-record table (name pointer, length,
start, size), a load-address header, and a MAP written after the PRG closes.
- First build failed because `out_rec_ptr` was in BSS; 6502 `(ptr),y` requires
zero page. Moved it to `ZEROPAGE`.
- Long branches in `out_begin` and `out_write_map` needed short-branch/`jmp`
trampolines.
- First x128 result was `OUT_ERR_ORDER`: the load-address header had advanced
`out_current` to `$1C03`, so the `$1C01` STUB section looked backward. The
writer now rewinds to `out_load` after the header.
- The next fixture exposed every PRG byte as `01`: `out_byte` loaded the section
flag into A before calling `out_put`. It now saves the byte first.
- Collision fixtures originally used PETSCII uppercase names while the writer
preserved the source's PETSCII lowercase names, so the writer legitimately
did not see them. Fixtures and host reads now use the same lowercase names.
- The abort fixture initially emitted a byte after `out_startup` had ended its
section, producing `OUT_ERR_STATE`; it now opens an explicit `X` section and
writes `$AA` before aborting.
- A stale parser-test x128 held port 6530 and caused empty/dropped monitor
replies. Verification identifies test-image processes and stops only those
before running.

## Completion

- Tests run:
- `scripts/build-output-test.ps1`
- `scripts/verify-output-test.ps1 -Port 6530 -RunPort 6531`
- `scripts/build-diag-test.ps1 -UpdateDocs`
- `scripts/verify-diag-test.ps1 -Port 6530`
- `scripts/verify-parser-test.ps1 -Port 6530`
- `git diff --check`
- Results: writer fixture PASS with results finish=0, collision=1, order=2,
abort=0; PRG and MAP bytes match; generated PRG autostarts with producer 3
and PASS; collision fixtures unchanged; abort/order outputs absent.
Diagnostics: catalog 71 entries, docs in sync, 19 screen rows and ERR files
exact. Parser: all 41 fixtures pass, lowest expression SP `$A7`.
- Files changed: `src/compiler/output.s`, `src/runtime/startup.s`,
`src/common/formats.inc`, `src/common/diagcat.inc`, `docs/diagnostics.md`,
`tests/codegen/output-test.s`, `scripts/build-output-test.ps1`,
`scripts/verify-output-test.ps1`, `docs/decisions.md`,
`docs/architecture.md`, `docs/memory-map.md`, this claim.
- Remaining risks: an existing output must be erased before recompiling
(refusal policy, D128); a power loss during direct PRG writing can leave a
partial file because there is no atomic rename; at most 8 sections and
12-character section names; the MAP has no symbols/class/interface entries
yet; the startup is only the mailbox/termination path and does not install
a runtime mapping; sections above `$3FFF` are E04-S02 work; `out_load` is
caller-controlled rather than validated against the fixed container.
