FA-33626 / Menu interactions / Open access
Parameter submenu completion skips its owning command menu · case 01
Parameter submenu completion skips its owning command menu.
ROOT CAUSE
The parameter-submenu model applies `[]` at its return-path operation instead of the stipulated transformation.
VERIFIED REPAIR
Apply `p['path'][:-1]` at return-path.
Unsuccessful approach: The attempted repair `p['path'][:-2]` still violates the return-path oracle.
Case contract
A parameter submenu binds a chosen parameter to a parent command while preserving other bindings; cancel discards provisional parameters and commit requires all required fields.
Why this case matters
Cascading and context menus require coherent command and session state as content changes.

Verification & scope
Offline supplied-valid-payload model; excludes DOM, keyboard, focus, selection, announcements and browser conformance. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
