graph-trajectory-hooks-smoke failed 3/3 times in CI on unmodified #3467
code (reverted my own unrelated attempt at a fix in the process — see
prior commit). Root cause identified: bridgeRecordFeedback()'s first-ever
call opens the AgentDB ControllerRegistry (new ControllerRegistry().
initialize({ embeddingModel: ... })), which resolves/attempts the ONNX
embedding pipeline before falling back to mock embeddings — a real,
one-time-per-process bootstrap cost. TEST 1 (trajectory-step on a
never-started trajectory) never reaches that code path, so TEST 2
(post-task) was the first and only call to pay it, entirely inside its
own <200ms budget: ~1000-1250ms on GitHub Actions' cold filesystem
cache, 20-46ms locally with a warm one. Added an explicit, untimed
warm-up call before TEST 1 begins so the one-time cost is paid during
setup, matching how a real long-lived Ruflo session actually behaves
(bootstrap once at startup, not per call). Verified 3/3 clean local
runs post-fix, TEST 1 now measuring 1-2ms (down from paying the same
hidden cost intermittently).
