sc-sweep.spec.ts

/**
 * T096 — Success-Criteria sweep against production.
 *
 * Each `test()` here verifies one SC item from spec.md. Runs against the
 * live production URL by default; override with `TARGET_BASE`.
 *
 * Coverage in this spec (locally observable, no live data needed beyond a
 * deployed site):
 *
 *   SC-002  search latency        — type into the search bar; assert the
 *                                   visible result count updates within 500 ms.
 *   SC-003  cell-switch timing    — change the model dropdown; assert the
 *                                   UMAP cell shard swap completes < 1.5 s.
 *   SC-004  mobile viewport       — 360 × 640 viewport has no horizontal
 *                                   scroll on the home page.
 *   SC-005  accepted-only         — the abstracts shard contains zero
 *                                   `accepted_for === "Withdrawn"` records.
 *   SC-011  footer build SHA      — home + about + abstract-permalink all
 *                                   render the same 7-char short SHA in
 *                                   the footer.
 *
 * Out of scope (need separate infra):
 *   SC-001  first interactive paint — measured by Lighthouse-CI workflow.
 *   SC-006  data-package size      — measured against the local build dir.
 *   SC-007  link check             — runs in deploy-ui.yml as a hard gate.
 *   SC-008  PR-preview timing      — observed manually across several PRs.
 *   SC-009  cart reload            — covered by cart_email + cart unit tests.
 *   SC-010  typo recall            — separate `eval_typo_recall.py` script.
 *   SC-012  AI-attribution         — separate Playwright assertion (TBD).
