From bdaeb16691cbfb8ebf2c19f97623b49fe9893ca1 Mon Sep 17 00:00:00 2001 From: RodCor Date: Sat, 30 May 2026 11:42:12 -0300 Subject: [PATCH 1/4] =?UTF-8?q?ci:=20make=20the=20gate=20green=20=E2=80=94?= =?UTF-8?q?=20fix=20test=20isolation=20+=20ignore=20unmaintained=20advisor?= =?UTF-8?q?y?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two blocking CI jobs were red on main after #3 merged: test (ubuntu + macOS): the previous HOME/TMP override does NOT isolate the per-user brain on Linux — the `home` crate resolves the home dir via getpwuid (/etc/passwd), ignoring $HOME. So CI kept resolving ~/.kimetsu and parallel test binaries contended on ~/.kimetsu/project.lock ("project writer lock is already held"). Fix: set KIMETSU_USER_BRAIN=0 for the test job (the documented toggle); every test then uses only its own per-test project root. Verified locally: full workspace all-green (14 test blocks, 0 failures). cargo-audit: RUSTSEC-2024-0384 (`instant` unmaintained) — a transitive, embeddings-only dep (fastembed -> sled 0.34 -> parking_lot 0.11 -> instant). Not an exploitable vuln and no upgrade path until fastembed bumps sled. Ignored with a documented reason; re-evaluate on fastembed update. clippy + cargo-deny remain advisory (continue-on-error) pending a cleanup PR. After this, the blocking checks (fmt, test, audit) are green.

Root cause is Cargo feature unification, not the lock contention the old ci.yml comment claimed: 'cargo test --workspace' unifies features across the graph, and kimetsu-cli enables 'kimetsu-brain/embeddings' by default. So kimetsu-brain's own test binary builds WITH the real fastembed embedder, never the noop the test assumed. The two near-duplicate texts ('thiserror' vs 'anyhow' error types) then exceed the 0.82 cosine threshold and a conflict row is recorded -> assertion fails. Make the plumbing test deterministic under any embedder: use two unrelated-topic memories (cosine well under threshold for a real embedder, trivially zero for the noop), rename to add_memory_distinct_texts_no_conflicts, and rewrite the doc/inline comments. Fix the misleading ci.yml comment to describe feature unification + the KIMETSU_USER_BRAIN=0 / --test-threads=1 hygiene. Verified: cargo test -p kimetsu-brain --features embeddings -> 98 passed, 0 failed (the exact CI build condition).
