/**
 * validate.ts — the Festipod validation matrix.
 *
 * SCOPE (2026-10-09, after the ActivityPods-first switch). Two layers are in
 * the gate:
 *
 *   (a) Festipod @ui  — the UI layer. The `@ui` tag does not exist in this repo;
 *       the layer is exactly the complement of the polyfill/broker tags, and its
 *       command is, verbatim:
 *         node --import tsx/esm node_modules/@cucumber/cucumber/bin/cucumber.js \
 *           --config cucumber.json \
 *           --tags 'not @wip and not @humain and not @data and not @e2e and not @multibrowser'
 *       `cucumber.json` additionally excludes `@suspendu` and `@e2e-activitypods`
 *       (Cucumber ANDs the config tags with the CLI ones), so this stays the
 *       stack-free UI layer exactly as verified at 125 scenarios / 0 failed.
 *
 *   (b) Festipod @e2e-activitypods — the smoke over the LOCAL ActivityPods stack
 *       (pod provider + Festipod backend + the app served for real). Distinct
 *       from the suspended `@e2e`: no wallet, no broker, so `cucumber.json`
 *       excludes it. Its config is `cucumber.smoke.json`; its reproducible setup
 *       is the concept note `data-layer`, `cookbook_local-activitypods-platform.md`.
 *       Requires the stack to be UP (the app server and Chromium are started
 *       here); an unreachable stack fails the layer rather than skipping it.
 *
 * SUSPENDED, NOT RUN HERE (documented skip, code preserved — nothing deleted):
 *   - `@data`, `@e2e`, `@multibrowser`, `@shared-wallet`, `@smoke` scenarios are
 *     polyfill/broker-bound: they sign the shared NextGraph wallet through the
 *     harness (`src/shared/test-harness/harness-ng.tsx`). They are tagged
 *     `@suspendu` in the feature files and excluded there, awaiting the NextGraph
 *     workstream.
 *   - the SDK's own tests (nextgraph/ng-eventually-js) are NOT Festipod's and are
 *     no longer run from here (concept `bdd-testing`,
 *     `rule_tests-validate-festipod-not-the-sdk`).
 *
 * A smoke layer that cannot reach its stack FAILS, loudly — it never silently
 * skips. Exit code is non-zero if any layer fails.
