Every command name is implemented by exactly one executable, and the other only delegates

184. Every command name is implemented by exactly one executable, and the other only delegates

Kontext

The shell tool bin/majordomus and the Rust executable share the name; share/commands.yaml describes one and the capability registry the other. A shell fallback once evaluated the model differently (318 vs 26 findings, 2026-10-12).

Rozhodnutí

Ownership is per command path (the program plus the full word sequence cli.yaml and share/commands.yaml declare) and is derived from the command graph's existing join of the two origins; a path both implement outside a declared delegation is a finding. Delegation stays read at run time from the generated projection docs/generated/cli.yaml (rule project.commands-are-projections, bin/majordomus:100-103): no delegation line is generated into or hand-written in bin/majordomus. The Rust executable is the target owner of every path, moved path by path with exit codes and machine output preserved.

Zamítnuté alternativy

• Keeping both implementations with a parity test forever
• An all-at-once rewrite of the shell tool

Důsledky

The session cutover (ADR 0047) and the automation milestone move paths one by one; doctor's agreement check becomes an ownership check over the command graph; a shared top-level word handed over by subcommand word is not a finding.
