+/**
+ * Request-contract guards for the Gemini Web executor (#9356).
+ *
+ * gemini-web is not an API client. It launches Playwright, types ONE flat
+ * prompt string into the gemini.google.com `.ql-editor` contenteditable,
+ * presses Enter, and captures the first `StreamGenerate` response off the page
+ * (see ../gemini-web.ts). There is no JSON request body on the wire, which
+ * makes two OpenAI controls structurally impossible to honor:
+ *
+ *   • `reasoning_effort` — no field exists to carry a thinking budget. Unlike
+ *     deepseek-web or perplexity-web, which post a real payload and can flip a
+ *     `thinking_enabled` flag or swap the model preference, there is nothing
+ *     here to set.
+ *   • forced `tool_choice` — the tools support gemini-web does have is the
+ *     prompt-emulation shim (`translator/webTools.ts`, #7286): it ASKS the
+ *     model, in prose, to answer with `<tool>{...}</tool>` and parses whatever
+ *     comes back. That is best-effort by construction. "required" / "any" /
+ *     a named function is a GUARANTEE, and a prompt cannot make one.
+ *
+ * Before this module both were accepted and quietly ignored, so an agent got a
+ * 200 with `finish_reason: "stop"`, no `reasoning_content`, and `tool_calls: []`
+ * and concluded its requirements had been met (#9356). Failing the request is
+ * the honest answer: the caller can drop the control, or route to a model that
+ * actually implements it.
+ *
+ * Deliberately NOT rejected — these are already satisfied or already work:
+ *   • `reasoning_effort: "none" | "minimal"` — asking for as little reasoning as
+ *     possible is something a non-thinking provider trivially complies with.
+ *   • `tool_choice: "auto" | "none"` and plain `tools[]` — the #7286 emulation
+ *     path, which several shipped combos depend on (#5240, #8488). Untouched.
+ *
+ * Pure and dependency-free so the whole contract is unit-testable without a
+ * browser.

+// Capability enforcement for the Gemini Web executor (#9356).
+//
+// Reported: gemini-web silently ACCEPTS `reasoning_effort` and
+// `tool_choice: "required"` and answers with ordinary prose — HTTP 200, no
+// `reasoning_content`, `tool_calls: []`, `finish_reason: "stop"`. An
+// AgentChakra/OpenClaw agent then believes its reasoning and tool requirements
+// were honored when they were not.
+//
+// Why neither can be implemented for THIS provider: gemini-web is not an API
+// client. It launches Playwright, types a single flat prompt string into the
+// gemini.google.com `.ql-editor` contenteditable, presses Enter, and captures
+// the first `StreamGenerate` response off the page. There is no request payload
+// to carry a thinking budget, and no function-calling channel to force — the
+// tools support it does have is the prompt-emulation shim (`webTools.ts`, #7286),
+// which ASKS the model to emit `<tool>{...}</tool>` and cannot GUARANTEE it.
+//
+// So this suite pins the issue's option (b) for both controls: reject the
+// requests we cannot honor, and keep honoring the ones we can. The line drawn:
+//
+//   reasoning_effort  none | minimal        → allowed (gemini-web not thinking
+//                                             IS compliance with "spend little")
+//                     low | medium | high…  → 400, a positive request to think
+//   tool_choice       absent | auto | none  → allowed (emulation path, #7286)
+//                     required | any | {fn} → 400, a guarantee we cannot make
