* chore(e2e): untrack gateway config and document e2e test location
Stop tracking tests/e2e/gateway/litellm-config.yml so the local proxy config stays on the machine
Add a note to CLAUDE.md that new e2e tests belong in tests/e2e/ and must follow that directory's conventions
* chore(e2e): add self-contained docker compose stack for local runs
Ship a docker-compose.yml that starts the proxy with a throwaway Postgres and Redis and inlines the proxy config with example models, so contributors can bring up a local gateway with nothing but a .env. Update CONTRIBUTING.md to match the inline-config flow
* chore(e2e): drop the second gemini deployment; one key is enough locally
* docs(e2e): make pre-commit steps ordered and require flagging internally found issues
tests/e2e/CLAUDE.md captures the harness code-style rules (suite-as-a-class, shared transport, typed pydantic models, Result/unwrap, markers, typing) and the coverage-registry naming grammar; CONTRIBUTING.md gets the Contributors Guide intro and a Setup section
The rust OCR smoke lived under tests/e2e/gateway and spoke raw httpx with
ad-hoc dataclasses, diverging from the rest of tests/e2e. Move it to
tests/e2e/llm_translation and rebuild it on the shared harness: typed pydantic
bodies in models.py (OcrDocument/OcrBody/OcrPage/OcrResponse), a Gateway.ocr()
route through the shared transport, Result/unwrap for outcomes, the e2e marker,
and the client/scoped_key fixtures. No test touches httpx or requests directly
now.
Behavior preserved: the config-presence check still reads gateway/litellm-config.yml
without a proxy, /model/info confirms the proxy loaded every rust-ocr deployment,
and each provider case asserts a well-formed OCR document over /v1/ocr.
Also add tests/e2e/CONTRIBUTING.md documenting the end-to-end testing flow so new
features land with coverage that walks the feature like production does.
