// Regression guard for #6562 — editing any existing OpenAI Codex provider
// connection returned "Invalid request" on save.
//
// Root cause: `createProviderConnection()` (src/lib/db/providers.ts) auto-
// increments a new connection's `priority` to `MAX(priority)+1` per provider,
// with NO upper bound — and OAuth-imported connections (Codex `codex-auth/
// import` and `import-bulk`, up to 50 accounts per call, callable repeatedly)
// never go through `createProviderSchema`'s Zod validation at all, so nothing
// ever capped that value at creation time. Codex's own bulk-account-rotation
// workflow (a common Codex workaround for per-account rate limits) routinely
// pushes a user well past 100 same-provider connections. `EditConnectionModal`
// always round-trips the connection's current `priority` unchanged on save
// (src/app/.../modals/EditConnectionModal.tsx `handleSubmit` — `priority:
// formData.priority` is unconditional), so the *existing, already-valid*
// priority gets resent as-is. `updateProviderConnectionSchema` capped
// `priority`/`globalPriority` at `max(100)` — a UI-only ceiling nothing on the
// create path ever enforced — so any connection whose priority had already
// grown past 100 failed re-validation on every single edit with "Invalid
// request", regardless of which field the user changed.
//
// Fix: raise the schema ceiling to `max(100_000)` — still bounded (a
// genuinely out-of-range value is rejected, see the control test below), just
// wide enough to accept priorities the app itself already produces.
//
// This test drives the real PUT handler with a realistic Codex OAuth edit
// payload (as EditConnectionModal.tsx actually builds it) against a
// connection whose priority already exceeds the old 100 cap, and asserts it
// validates + persists instead of 400ing with "Invalid request".
