EMULATORS FMT Audit

Audit the complete contract from a C++ producer to its runtime text output:

getInfoStructure() -> documented fields in .hpp -> formatter block -> including machine .fmt -> command/output stream

Read references/fmt-language.md completely before creating or changing a .fmt file.

Workflow

1. Identify every relevant getInfoStructure() implementation and its inheritance chain.
2. Record each exact result.add ("KEY", ...) as either an attribute or a nested InfoStructure.
3. Include inherited fields only through the documented parent contract. Do not guess keys from member names.
4. Compare the actual keys with the Doxygen block immediately associated with the declaration in the .hpp.
5. Locate formatter blocks by .CLASSNAME, nested key name, and command wrapper name.
6. Follow every leading ?path.fmt include recursively. Resolve paths as the runtime does from the emulator working directory/configuration.
7. Compare formatter placeholders with actual keys and report missing, stale, and mistyped fields.
8. Check all source machine variants under projects that include the shared formatter, especially normal and remote consoles.
9. Propose or apply the smallest synchronized change across C++, .hpp documentation, and .fmt.
10. Validate the formatter parse and, when possible, format a real InfoStructure through the formatter used by the command.
11. When the formatter belongs to a C64, VIC-20, C264, ZX80, ZX81, ZX Spectrum, or MSX command or changes its documented visible output, review and update the corresponding maintained guide: docs/C64Emulator_UserGuide.docx, docs/VIC20Data/VIC20Emulator_UserGuide.docx, docs/C264Data/C264Emulator_UserGuide.docx, docs/ZX81Data/ZX81Emulator_UserGuide.docx, docs/ZXSpectrumData/ZXSpectrumEmulator_UserGuide.docx, or docs/MSXData/MSXEmulator_UserGuide.docx. Verify local-console and remote-channel availability through the full effective command-builder chain, including the currently duplicated MCHEmul::StandardCommandBuilder link constructed by the MSX entry points.

Contract rules

• Treat key spelling and case as an API.
• Document every field added by the method, with exact formatter spelling.
• Classify nested data as InfoStructure, not Attribute.
• Preserve inherited formatter blocks unless the subclass changes the exposed structure.
• Missing attributes and nested structures produce empty text and can hide stale placeholders. Audit explicitly.
• Treat .fmt files under projects as the canonical sources. A full all build from the repository root distributes them intelligently to emulators, monitors, setups, and any other runtime/package destinations.
• Do not edit distributed .fmt copies outside projects unless the user explicitly requests it. After changing canonical files, use the normal all build/distribution workflow when validation of copies is required.
• Keep shared chip formatters in projects/COMMODORE/Commodore.fmt when several machines consume the same class.
• Keep machine command wrappers in their machine namespace .fmt.
• Update both local-console and remote-console source entry files under projects when they duplicate rather than include a definition.
• Preserve comments, block ordering, indentation, and CRLF conventions.

Search commands

rg -n "getInfoStructure|result\\.add" include/COMMODORE src/COMMODORE
rg -n ";(CIA|VIA|TED)|@(CIA|VIA|TED)" projects --glob "*.fmt"
rg -n "\\?\\.\\/.*\\.fmt|;[A-Za-z0-9_.-]+|@[A-Za-z0-9_.-]+[?>]?" projects --glob "*.fmt"

Use git diff to identify newly added, removed, or renamed keys, but verify the complete current method rather than auditing only the diff.

Reporting

Separate findings into:

• confirmed mismatch;
• missing presentation;
• stale presentation;
• optional presentation;
• inheritance/include dependency;
• validation limitation.

For every proposed change name the class, method, header, formatter block, and all affected canonical .fmt entry points under projects. Do not list distributed copies as files to edit; mention that all will regenerate them when relevant. Do not modify C++ or .fmt when the user requested analysis or proposals only.
