tests: unit + integration suite (99 tests; ruff + mypy --strict clean)
Real test bodies (not stubs), driven against an in-process httpx.ASGITransport override of the gateway's get_ollama_client dependency pointing at tests/integration/mock_ollama.py. Unit (target 100% on auth/, ratelimit/, budget/): - argon2id roundtrip, wrong-key, garbage encoding, needs_rehash on param change - key format/uniqueness/prefix extraction - token counter (prompt_eval_count + eval_count, embeddings, missing-counts) - translate (OpenAI <-> Ollama for chat/completion/embeddings, streaming chunks, /v1/models list shape) - allowlist (hard-blocks, effective-set semantics across allow_all/inheritance/ empty-discovered) - discovery (parse, cache roundtrip with TTL, fail-closed, tolerates redis=None) - sliding window (allow/block/reset/per-key vs per-tenant/cost-weighted) Integration (testcontainers postgres + redis + in-process mock Ollama): - auth flow (no/malformed/wrong key all return identical sanitized 401) - proxy stream (NDJSON roundtrip, audit row's token counts match, hard-blocked endpoints uniformly 403) - openai_compat (SSE chunks, data: [DONE], non-stream shape, /v1/models) - model_discovery (allow_all sees all, default-deny sees allowed ∩ discovered, /v1/models filtered, unpermitted-but-installed = nonexistent = 403, empty cache denies even allow_all) - rate_limit (429 + Retry-After + headers; Redis down ⇒ 503, never 200) - budget (decrement + headers; pre-burned counter blocks next request) - revocation (INSERT into gateway.revocations → NOTIFY → cache evicted → 401 ≤ 1s) Includes a known-issue xfail flagging a bug in ratelimit/sliding_window.py: the per-hit ZSET member uses id(object()) which returns the same id on consecutive calls, causing same-millisecond hits to overwrite instead of stacking. To be fixed in a follow-up commit.

"""Integration tests for the native Ollama proxy (streaming + non-streaming).

NDJSON end-to-end through to the in-process mock upstream; the gateway preserves

the byte stream untouched and the audit row that lands after stream close
