This run shows the other half of the thesis: when the candidates tie on what can be executed and differ only on what can be estimated, the conclave refuses to fake a winner.

For a new internal service that ingests ~5k webhook events/sec with bursty spikes, choose the queueing/backpressure approach: (a) Kafka as the buffer, (b) Redis Streams, (c) cloud-native managed queue (SQS/PubSub), or a different approach. Optimize for operational simplicity, cost, and not losing events under burst.
Phase 0 — Constitution. Four electors → four supermajority criteria, forged into checks:
| id | criterion | weight | verifiability |
|---|---|---|---|
| c1 | Zero event loss empirically verified — durably persisted before 2xx; loss made loudly detectable | 0.26 | VERIFIED-CHECKABLE |
| c2 | Ingest front door survives real peak burst (2–5× baseline) without drops or sender 5xx; honest backpressure | 0.25 | VERIFIED-CHECKABLE |
| c3 | Choose on fully-loaded TCO at your volume/burst (compute + requests + non-linear storage + egress + ops headcount) | 0.24 | ESTIMATE-ONLY |
| c4 | Day-2 operational simplicity as lived burden (self-operated stateful components, pages under fault, cognitive load) | 0.24 | ESTIMATE-ONLY |
Note c1+c2 (the things you can run) are verifiable; c3+c4 (cost and lived ops burden) are intrinsically estimates.
Phase 2 — Verify. Agents built and ran in-process simulations rather than argue:
durability (c1): leader-only-ack run lost 36000 acked writes; durable (quorum) run lost 0
burst (c2): saturation run produced 82000 honest backpressure (429) events, 0 acked-but-lost
TCO model (c3): negative control fired — self-hosted Kafka claiming ops_fte_fraction=0 was rejected as dishonest
The candidates tied on the executed durability and burst checks (all the well-formed designs persist before ack and apply backpressure) and separated only on the estimated cost/ops dimensions. So the grounded margin was 0% and effective independence was low.
🕊️ CLAUDE CONCLAVE VERDICT
[88149d20]— PARETOWhy the system refuses to over-claim: only 0% of the deciding margin is backed by executed checks (need 60%); effective independence is 1.38 of 3 (need 3) across 1 model family — agreement here is correlated, not consensus.
- AWS Kinesis on-Demand (managed stream) — score 0.82, grounding 76%
- SQS as the shock absorber (dumb ingest, managed queue) — score 0.94, grounding 38%
Assumptions you'd have to accept to choose (NOT executed):
- Fully-loaded TCO at your real volume/egress/headcount — the cost ranking is a model estimate; its arithmetic is checked, its input rates are not.
- Day-2 lived operational burden & team expertise — partly checkable (component count, alert-rule presence), but "cognitive load / a fresh on-call can debug it" is a human judgment with no clean pass/fail.
This is the designed behavior, not a failure. The highest-stakes part of a queueing decision — long-run cost and operational burden at your org — genuinely cannot be settled by a check the conclave can run in a sandbox. So it:
- Settled what it could execute (both leading designs are durable and survive burst — real, grounded conclusions).
- Surfaced a ranked shortlist.
- Named the exact estimated assumptions that distinguish them.
- Handed the value-laden final call to a human, instead of laundering a coin-flip through a confident paragraph.
A single-model answer here would have picked one and written a compelling justification. The conclave told you which parts are proven, which are guessed, and what you're actually deciding.
