[corpus] Fixture: gemini-python-genai (google.genai SDK — module/function/with-scope clients)

[AndresL230]

Part of #10. Validates recost-dev/extension#143.

Goal

A fixture exercising the Python google.genai SDK (genai.Client().models.generate_content), including a client constructed in a function scope and one in a with block. The extension detects none of these today (provider resolves to "google" with no fingerprint, and inner-scope client vars aren't tracked).

        contents=text,

FIXTURE.md

Synthetic fixture authored for the ReCost benchmark (no upstream source). Scope: the from google import genai → genai.Client().models.* SDK shape, covering module-level, function-scope, and with-block client construction. License: n/a (synthetic).

Current behaviour (the gap)

• processPythonAssignment (import-resolver.ts:497) maps client = genai.Client() → package "google" (import segment); "google" is not in PACKAGE_TO_PROVIDER, so resolveProvider yields provider "google", no fingerprint, dropped at core-scanner.ts:269.
• local_client / with … as c are inner-scope and aren't bound at all.
• Expected current result: 0/4 detected → detectionRecall miss on this fixture.

Flips green when

recost-dev/extension#143 lands (map google.genai/google.generativeai → gemini, track inner-scope client vars, register the models.generate_content/models.embed_content chains).

Acceptance criteria

• Fixture added with the two src files + expected.json + FIXTURE.md.
• Runner output records the current 0/4 recall for gemini-python-genai.
