Two server-aligned signals on save paths:
- +Add row button: fetches /.profile/access?path=<current dir> via
zddc.cap.at() once on load; if path_verbs doesn't include 'c'
the button disables with a tooltip ("You don't have create
access in this folder."). Async race-window is the same as any
other path-scoped fetch — server still gates the POST so a
stale client gets a 403 toast on click rather than a silent
accept.
- 403 on save/create: previously fell into the generic
"http-error" bucket with a console warn; now branches into
zddc.cap.handleForbidden which renders an error toast naming the
missing verb. When the path-scoped view reports an elevation
grant covering that verb, the toast appends an Elevate button.
Per-row writability stays computed server-side for now — tables
walks rows via FS-API-style handles that don't surface the listing
verbs string. A follow-on pass can switch the row walk to raw
listing entries and gate row.editable on each entry's verbs.
