There was a problem hiding this comment.
For HTTP publishes, routes/interactions.py always supplies a request_id and admission_participant retains its default of None, so the earlier condition at lines 212–215 performs another storage.get_request(request_id) before reaching this phase. On remote storage, that first round trip remains unattributed while dup_check_ms records only the second lookup, leaving a material gap and understating duplicate-check time; wrap the preflight lookup in the same accumulating phase as well.
Useful? React with 👍 / 👎.

46-46: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick winStub local extraction in these timing tests.
Each real publish enters
post_publishand starts a daemon scheduler throughensure_local_extraction. The fixture removes the temporary directory without stopping that scheduler. The lifecycle code retires it only after a later publish detects the collected context, so the scheduler can remain alive during the next test.This is a bounded test-isolation issue, not persistent scheduler accumulation. The stub preserves
post_publishtiming because the phase surrounds the call.Suggested fix

Review on #536: the comments read 59/59 as if it measured the exit they are attached to. It does not. 59/59 is the CLIENT giving up; only 11 of those never left the admission queue, which is what the route's emit reports. The other 48 were already admitted, committed, and reported by the worker. So the route exit is the minority case (~19%), not "the dominant production outcome" -- and calling the 460 rate its frequency points a reader at the wrong problem, which is the same mistake the paragraph was written to stop. All three sites now state the three counts separately: routes/interactions.py's BaseException comment, the timing test module header, and the cancelled-while-queued test's docstring.

Addressed in The finding was correct, and the conflation was mine: 59/59 measures clients giving up, not the exit the comment is attached to. Separating the three counts:
So the route's emit covers the minority case, and the old text called it "the dominant production outcome" — which points a reader at the 460 rate when the thing this branch actually handles is about a fifth of it. Rewritten at all three sites: the

ruffclean.A near-miss worth recording
The first version of the
coverage_readstest passed against unmodified production code: it opened the phase itself around_safe_coverageand then asserted the phase existed — it was measuring its own wrapper. A test that supplies the thing it checks for cannot fail. The committed version drives the library path and went properly red before the fix.What this does not do
It attributes; it does not accelerate. No publish gets faster from this change. What changes is that the next line says where the 68% goes, and
scope_commitfinally distinguishes "the commit is slow" from "we queued for a connection".Related: ReflexioAI/reflexio-enterprise#1371 makes a saturated pool visible, which is the other half of the same investigation.
