Three small helpers under window.zddc.cap, wired into every tool's
build:
cap.at(path) — Promise<AccessView|null>. Fetches
/.profile/access?path=<urlpath> and
memoises per-path for the session.
Used by tools to gate top-of-page
affordances on path_verbs / path_is_admin
/ path_can_elevate_grant.
cap.has(node, verb) — boolean. Reads the listing entry's
verbs string for the named verb.
Falls back to node.writable for 'w'
when verbs is absent (offline FS-API
listings or pre-promotion clients).
cap.handleForbidden(resp, — parses a 403 response's JSON body for
opts) missing_verb and renders an error
toast. When opts.path is supplied AND
the path-scoped access view reports
path_can_elevate_grant covering the
missing verb, the toast appends an
"Elevate" button that flips the
elevation cookie and reloads.
Browse loader.js + tree.js carry the new verbs field through to the
node objects so context-menu gating can call cap.has(node, 'w'|'d')
without changing the legacy node.writable contract. New CSS rule
.zddc-toast__action styles the inline Elevate button.
Concatenation order: cap.js comes after toast.js + elevation.js so
the dependencies (window.zddc.toast, window.zddc.elevation) are
present at module-load time.
