The Q3 2025 cross-axis methodology review pool concluded its quarterly review on 18 October. As is now standard practice, we publish the public-interest portions of the minutes here. Items covered: MUR protocol v2 amendment (status), the federated scheduler v2 transition (status), the soft-stopping-condition specification (review), and two items from the open compute grant programme.
MUR protocol v2 amendment. The amendment, introduced after the 24-13 halt, has been in 11-month review. The pool reached a working conclusion that the amendment should be finalised in Q4 with one additional revision: a tighter specification of what "soft escalation" looks like in trace-store metadata. The amendment will go to a charter-class proposal vote in early Q4. Discussion was vigorous; the minutes record three substantive disagreements that the pool worked through during the meeting.
Federated scheduler v2 transition. v2 has now been GA for one full quarter. The pool reviewed the post-GA operational metrics: zero unplanned outages, two planned maintenance windows with the standard advance notification, and 94% allocation-decision parity with the shadow-mode v1 that ran alongside for the cutover. The pool noted no concerns and approved closing the dual-mode operation in early Q4.
Soft-stopping-condition specification. The specification, which extends the MUR protocol to introduce a flag-then-escalate tier between proceed and halt, was reviewed in detail. The pool's majority view is that the specification is operationally sound; the minority view is that introducing any intermediate state increases the risk of false-negatives on halt-worthy events. The minority view is now recorded as a formal dissent in the specification's accompanying note, per policy.
Open compute grant programme. Two items: first-quarter application volume and committee composition for Q4. The pool noted that the first round received 47 applications, of which 9 were funded and 6 were funded under a smaller-than-requested award. The committee composition rotates quarterly per programme rules; the Q4 committee is now named in the minutes.
Items not reviewed. The pool did not review the partnership with Constellation (already approved through partnership-class vote in February). The pool did not review the contributor-cohort intake for 2026-Q1 (cell-level governance). The pool did not review the publication-policy tier-3 holds (which are reviewed annually in Q1, not Q3).
The minority view is now recorded as a formal dissent in the specification's accompanying note, per policy.
Attendance. Of 142 long-tenured contributors, 89 attended at least partially; 71 attended in full. The 71/142 ratio is comfortably above the 50% turnout floor for review-pool decisions. Attendance by location: 18 Bay Area, 14 Colombo, 11 Hong Kong, 7 Bali, 21 distributed.
Next review pool: 14 January 2026. As always, the pool's agenda is set by the rotating chair (Q1 chair: Hester Vandekerckhove) in consultation with the axis stewards. Items to be added to the agenda should be submitted by 7 January via the standard channel.
Two procedural notes for the record. First, the pool experimented with a structured pre-read period in this cycle: agenda items were circulated 10 days ahead with required-reading and recommended-reading splits, in an attempt to reduce the in-session time spent on basic catch-up. The experiment was judged a success by the rotating chair and will be standardised in Q4. Second, the pool has begun publishing item-level discussion summaries (in addition to these public minutes) to the internal index; these summaries are not for public release in their entirety but excerpts may be cited in subsequent public posts.
A final note on tone. These minutes are public by policy. They are not edited for tone after the fact, beyond the standard correction process. If anything in them reads as harsher or terser than expected, that is generally because the discussion was — and the lab's preference is to preserve that signal rather than smooth it out.
