FA-23009 / Autocomplete interactions / Member archive

Hierarchical path autocomplete: accepting a directory omits the next-segment separator · case 04

The directory-suffix completion transition produces an incorrect observable state.

Case contract

Path autocomplete treats the prefix before the last slash as lookup scope and replaces only the final segment. Directory acceptance appends a slash and keeps completion active; leaf acceptance commits. Empty final segments request children, and responses bind to the exact parent path.

Why this case matters

Autocomplete couples draft text, suggestion identity and asynchronous presentation; this bounded lifecycle model isolates one observable interaction defect.
