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.

Promote classifier's local toast (classifier/css/base.css + showToast
in classifier/js/excel.js) into shared/toast.{js,css}. Every tool's
build.sh now concatenates them, so window.zddc.toast(msg, level, opts)
is callable from any tool.
API:
window.zddc.toast('Saved.', 'success');
window.zddc.toast('Could not load: ' + err.message, 'error');
window.zddc.toast('Note', 'info', { durationMs: 3000 });
Levels: info (default) | success | warning | error. Single-toast
policy — a second call replaces the first. Click anywhere on the
toast to dismiss. ARIA: error → role=alert/aria-live=assertive,
others → role=status/aria-live=polite.
Class prefix is .zddc-toast (BEM-ish) to avoid colliding with any
tool-local .toast rules. Classifier's existing showToast now
delegates to window.zddc.toast — call sites in excel.js +
selection.js are unchanged. Classifier's local .toast CSS block
deleted in favor of the shared one.
This commit only EXPOSES the API. Replacing the ~25 alert() call
sites scattered across archive/transmittal/mdedit/classifier with
toast calls is left as follow-up — each alert needs per-call review
to decide if it's truly non-blocking.
Five Playwright tests in tests/toast.spec.js lock the contract:
API exposure, level mapping, ARIA roles, single-toast replace,
click-to-dismiss.
