/**
 * A delegate who may write: what they are offered, and what they are not.
 *
 * The unit suite runs SSR-only, so it holds the PAINT and never the click: it
 * can prove an add button is absent, which is the property that matters most,
 * and it cannot prove that the one still standing submits. This spec is the
 * other half — a real form, a real POST, a real row in somebody else's record,
 * and the owner seeing it afterwards.
 *
 * ## Why it gates itself instead of seeding a WRITE grant directly
 *
 * The grant level is chosen in the invitation form. Rather than mint a WRITE
 * row behind the UI's back — which would prove the journey works for a grant
 * no person can create — the journey looks for the level control and stands
 * down when it is not there yet.
 *
 * That guard was written against a `data-slot` the form never shipped under
 * (`grant-invite-level`; the control landed as `grant-invite-access-option`),
 * so from the day the control arrived until 2026-08-03 every test in this file
 * skipped and the whole delegated-write journey ran nowhere. The file said out
 * loud what to change and nobody changed it, which is the standing lesson
 * about a check that cannot fail: the skip is quiet, and a quiet skip and a
 * passing suite look identical in a CI summary.
 *
 * The constant is the real one now. If it moves again, change that one string:
 * nothing else here assumes anything about the control except that choosing
 * WRITE and submitting mints a WRITE grant.
 *
 * ## What this spec cannot cover
 *
 * The owner's activity view is asserted at the level of "a row appeared for
 * something the delegate did", not at the level of the per-verb sentence. The
 * verb lines live in `src/lib/record-activity/activity-verb.ts` with their own
 * unit test; the one line that binds them into the activity card belongs to
 * the file this chunk was told not to touch.
