/**
 * AI Software Factory — RELEASE v1.0 FINAL E2E FLOW (TASK-0135, spec L242–266).
 *
 * Thirteen SEQUENTIAL steps (one browser context + one Bearer API context,
 * state carries across the whole flow — "one project, sequential"):
 *   1 register · 2 verify · 3 workspace · 4 page · 5 editor DnD reorder ·
 *   6 database + 3 records · 7 relation + formula · 8 global search ·
 *   9 10 MB upload · 10 anonymous public form · 11 automation → notify ·
 *   12 AI (mock) · 13 API key + signed webhook + logout.
 *
 * TARGET (spec L245): the STAGING URL. Environment gates:
 *   E2E_STAGING=1  — targets deployed staging; the four staging-only steps
 *                    (2 mailcatcher verify, 9 10 MB S3 upload, 10 anonymous
 *                    form context, 12 mock-AI stream) are ENABLED.
 *   E2E_RUN_ID     — unique per run; the register email is
 *                    `final-e2e-<runId>@factory.local` (spec step 1).
 * Without `E2E_STAGING=1` (a local dev run) those four steps NO-OP with a
 * rule-29 annotation — the capability genuinely does not exist on the dev box
 * (no mailcatcher / reachable S3) and is never faked green. Step 9 additionally
 * probes S3/MinIO reachability at runtime and skips when storage is down.
 *
 * CONTRACT CORRECTIONS vs. the earlier draft (each verified against the live
 * API + web source in TASK-0135 — see the release report):
 *  - Databases are created via `POST /workspaces/:ws/pages {type:"database"}`
 *    (there is NO `/workspaces/:ws/databases` route). The seeded page carries
 *    `databaseId` + a title/Status property set (DEFAULT_DB_PROPERTIES).
 *  - Records are keyed by PROPERTY ID (propertyId → value), NOT property name —
 *    a name-keyed `properties` body is a 400 `unknown_property`.
 *  - Search is `POST /search { q }` (GET /search is a 404).
 *  - Public forms live on `POST /databases/:id/forms` (not a workspace route),
 *    published with `PATCH /forms/:id {status:"PUBLISHED"}`.
 *  - The formula engine cannot compare a SELECT value (`prop("Status") == "x"`
 *    → 400 "unsupported value type"), so step 7 uses the canonical
 *    `isOverdue = dateBetween(prop("Due"), now()) > 0` (returns a boolean),
 *    asserted `value === true` on the overdue record via the engine endpoint.
 *  - The `api` Bearer request context carries NO cookie (cookies are captured
 *    into the browser context), so a refresh-after-logout issued from it is
 *    vacuous (401 with or without logout). Step 13 logs out via the real UI and
 *    then refreshes from the cookie-carrying browser context, so the 401 is
 *    genuine (the logout revoked the refresh token server-side).
 *
 * Selectors: only testids that exist in the current web tree (`block-{id}`,
 * `drag-handle`, `search-result`, `ask-ai-button`, `file-card-{id}`, …).
 * Deliberately avoids the stale `sidebar-page-{id}` (documented in
 * fixtures.ts/README but never rendered — see perf-report §8 pre-existing
 * drift); pages are reached by URL (`/w/<ws>/page/<page>` — the web route is
 * `page`, not `p`), which is deterministic.
 *
 * NOTE: this is a faithful implementation of the 13-step contract. The four
 * staging-only steps run against staging (their real target); the API-state
 * steps use source-verified inline API calls (the `tests/e2e/utils/api.ts`
 * `createDatabase`/`createRecord`/`queryRecords`/`search` helpers are stale
 * against the Phase-13 contracts and are intentionally NOT used here).
