From 5af50397ea0d4148ff6fb8041dc77e875840f551 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 3 Jul 2026 00:39:04 +0000 Subject: [PATCH 1/6] Add OAK adapter parity tests + benchmark harness for reachable_from closures Choosing an OAK adapter for reachable_from closure validation affects both correctness and performance, and the wrong choice fails silently (OLS truncates -> false rejects, #55; Ubergraph is multi-ontology -> false accepts, #58; owl: is O(V*E), #57). This adds two complementary pieces: - tests/test_adapter_parity.py: deterministic, cache/timing-independent behavioral invariants safe for CI. * Offline: simpleobo / pronto / owl must agree on is_a and is_a+part_of closures over a synthetic ontology (also documents that pronto needs a part_of Typedef declaration). * Integration (network): OLS closure is a subset of ground truth (does not over-return); Ubergraph descendants span multiple ontologies and its GO-scoped subset is strictly smaller (must prefix-filter). - benchmarks/: standalone, cache-isolated timing harness (adapter_benchmark.py) that reports cold+warm closures per adapter and regenerates the comparison table; README.md with the adapter selection guide and the two failure modes; results/go_adapter_comparison.md as a captured reference run. Wired up as `just benchmark`. Performance is never asserted (it depends on download/HTTP caches); correctness is. Full suite green: pytest, mypy, ruff.

Each adapter now runs in its own subprocess (--worker); ru_maxrss is that adapter's true peak, and cache isolation is genuinely per-adapter. - Downloader was missing a User-Agent and 403'd against the OBO hosts/proxy; now sends one (verified against a live fetch), so `just benchmark` works end-to-end. - Meta line rendered as a stray table row -> now a "> Run:" blockquote caption. - OAKLIB_CACHE set unconditionally like the other cache env vars (with a comment on why an inherited value would defeat isolation). - Documented the is_a-first ordering the ancestor sample relies on. - test_adapter_parity: local_adapters is now a session-scoped fixture with a `len < 2` skip guard so parity can't pass vacuously. Not applied: the "assert source_node not in closure" suggestion -- this test drives raw adapter.descendants (reflexive=True by OAK default); source exclusion is plugin-level and already covered by test_reachable_from_progressive.py. The committed reference table is regenerated authentically in a follow-up commit.
