Subject: [PATCH] test(e2e): AI provider dropdown switches the rendered config
 form
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Locks in the B2 contract: /settings/ai exposes the active-provider
Pulldown, switching the dropdown swaps the form below it (Codex →
OpenAI → Anthropic → Local), and the fallback chain card surfaces
all configured rows with their stable data-chain-row markers.

The spec mocks every backend endpoint the section reads so the run
needs no real Codex / OpenAI keys in CI. data-testid markers on each
config form keep the assertions independent of the locale.

+/**
+ * v1.4.16 phase B2 — AI provider settings UX with single dropdown
+ * driving the form below. Three things to lock in here:
+ *
+ *   1. /settings/ai exposes the active-provider Pulldown
+ *      (`data-testid="ai-active-provider-select"`).
+ *   2. Switching the dropdown changes the rendered config form below
+ *      it: Codex form vs. OpenAI form vs. Anthropic form vs. Local
+ *      form. Each form carries a stable `data-testid` so we don't
+ *      lean on i18n labels.
+ *   3. The fallback chain card surfaces with stable
+ *      `data-chain-row="<providerType>"` markers per row.
