Added

• Commands can now keep unconditional produces beside an attached handler whose body is a nonempty language-tagged code fence or a resolved file. The pair binds in executable model v23, and produces acts as the handler's fixed result contract. Bodies remain opaque: reference execution still reports body execution as unsupported, and a target must admit the language and implementation separately. (Research source-native command-handler admission without weakening PLAY0800 #1068)

Changed

• PLAY0035 is retired and no longer reported. Attached handlers without unconditional produces, or without a resolved nonempty body or a known file language, keep reporting PLAY0800.
• A command that declares more than one attached handler, including across composed command fragments, now reports a duplicate declaration (PLAY0168) instead of letting one body replace the other.

Corpus impact: tracked in Cratis/AI#945 (attached handler admission, PLAY0035 retirement, PLAY0800 narrowing, duplicate attached handlers).

Reviewer notes:

• Owner whole-change review (Claude Opus + GPT Sol) passed with zero findings on the branch merged with main (base 4e4791a).
• The local gate at f744336 passed: Release build with 0 warnings, Debug specs (18,922; 3 Windows-only skips), Release canonical vectors (725), and JavaScript build, compile, lint and tests (10,639).
• Windows/Linux desktop, VSIX packaging and external integration lanes are CI-only.
• Scope is compiler admission only. Stage rendering and execution of attached bodies is tracked separately in Render body-carrying command handlers beside productions in the Cratis target Stage#817 and is not claimed here.
