// #429 — Phase 8 omantel handover DoD scaffold.
//
// What this spec does (and ONLY what it does):
//
// This is the executable Definition of Done for Phase 8 of the omantel handover
// (#369). Today it is a SCAFFOLD — when run on contabo or any developer
// machine without the three required env vars below, every test self-skips so
// it never breaks the routine `npx playwright test` run. When Phase 4/6/7 land
// and the first omantel.omani.works Sovereign comes up, the operator runs
// `.github/workflows/omantel-e2e-handover.yaml` against it and these tests
// flip GREEN.
//
// Required env vars (all three must be set, else the suite skips):
//
//   OMANTEL_BASE_URL   — e.g. https://omantel.omani.works         (console)
//   OMANTEL_API_BASE   — e.g. https://api.omantel.omani.works     (catalyst-api)
//   OPERATOR_BEARER    — bootstrap operator JWT for admin API calls
//
// Optional env vars:
//
//   OMANTEL_SOVEREIGN_ID — sovereign id to read back (default `omantel`)
//   CONTABO_API_BASE     — used by the "zero contabo dependency" test to assert
//                          omantel responds with no fan-out to contabo. Default
//                          https://api.openova.io  — we DO NOT call it in the
//                          self-sufficiency assertion; we just record what we
//                          would have called.
//
// Per `tests/e2e/playwright/tests/_helpers.ts` (`reachable()`), preflight uses
// a single fetch; if the omantel API is unreachable we mark skipped rather
// than fail. Same discipline as #142 sovereign wizard smoke.
//
// Per `docs/INVIOLABLE-PRINCIPLES.md` rule 4 ("never hardcode"), all targets
// come from env vars. Per the same doc's rule 1 ("never speculate"), assertions
// are written against the canonical post-#425 secret name
// `flux-system/object-storage` — NOT the deprecated hetzner-coupled name.
//
// Per CLAUDE.md "Phase 8 — End-to-end omantel run + DoD verification" (WBS §5):
// the six tests below correspond 1:1 to WBS §10 acceptance bullets, in order.
