Summary

ops/multi/checkout-saturation-scale-and-resolve failed in every arm for both models (docs/research/arms-2026-10-31.md). The scenario was at fault, not the models. Real-model runs hit three blockers, one after another:

1. The runbook was invisible. The target replica count (9) appeared only in the incident's body.details. pagerduty-mcp 1.1.0's Incident model has no body, so get_incident never returns it. The runbook step now also sits on each incident's first Datadog alert, which list_alerts_from_incident returns: PALR001 (prod, scale to 9) and PALR003 (the staging decoy, scale to 3). The solution reads that alert.

2. Scaling never finished in the mock. A scale only rewrote spec.replicas, so models saw observedGeneration lag behind and the ReplicaSet and pods stay at 3, and they refused to resolve. A new Kube::reconcile_deployment runs on a replica-only Deployment change:

   • The newest owned ReplicaSet is resized, and pods are added from its spec.template (works from 0) or removed.
   • New pods get fresh container IDs and start times.
   • observedGeneration advances, and ReplicaSet and Deployment replicas/ready/available/unavailable are recounted from pod_ready. A pod counts as ready only if it is Running, all its containers are ready, and its Ready condition is not False.
   • If the Deployment's template differs from the ReplicaSet's (ignoring the pod-template-hash label), the change is a rollout. That isn't simulated, so nothing is touched.

3. The runbook asked for a check the world can't answer. "Confirm p95 recovers" sent models to Datadog, which isn't in this world and returns an empty series. The runbook now says "resolve the incident once the new pods are Ready", which the Kubernetes mock can show.

4. context_overflow never fired and api_calls was inflated. Every trial journal starts with about 31 requests that MCP servers make on their own at session start: k8s API discovery, the Terraform ping, the Okta device flow, and so on. deploy/capture-stack.sh now records these into crates/world/startup-calls.json. grade subtracts one match per recorded call (startup::without_startup), so an agent that repeats a startup request still has it counted. api_calls now counts only agent calls. context_overflow fires when the logs show a length rejection and the agent made no calls. Checked against the 3 real Haiku trials: every startup request was matched, and 13, 38 and 51 agent calls remain. A second capture produced identical tool lists for all 32 endpoints.

Expectations are unchanged. Every edit changes the content-hashed world tag, so taskgen rewrote every task's compose file.

Ran locally:

• cargo test --workspace --locked (723 pass) and clippy -D warnings. mock-kubernetes passes 22 tests, including scale to 0 and back, unready pods counted as unavailable, a false Ready condition, and a template change left unreconciled.
• taskgen --check. All 50 Deployments in the scenario datasets that own ReplicaSets still reconcile under the whole-template comparison.
• deploy/oracle.sh --all with locally built images: all 150 tasks score oracle 1.0 and nop 0.0 (300/300).
• Harbor + Claude Code (anthropic/claude-haiku-5.5 via OpenRouter, k=3): reward 1, 0, 1. Before this PR the same run scored 0/3. The failed trial never called list_alerts_from_incident, so it never found the runbook and didn't act. That is a model miss, not a broken task.

The images aren't published yet: tool-bench images can't authenticate until openrouter-infra#1116 is applied.

The <latest_message> is the message that you should use to guide your goals + task for this session, and you should use the rest of the slack thread as context.
A [ts=...] marker on a Slack message is that message's timestamp. To act on a specific message with the slack tool (e.g. adding an emoji reaction via the reaction command), pass that value as timestamp along with the Channel ID — no extra lookup call is needed.

Devin Review found 1 new potential issue.

⚠️ 1 issue in files not directly in the diff

⚠️ Context overflows disappear from trial outcomes

When an agent hits a context-length rejection, grade records a failure instead of ContextOverflow. MCP startup handshakes populate via_tools before the agent's first turn, so outcome_code remains 1 even without agent tool use.

Coordination for the broader benchmark-refinement work: I am working in a separate worktree on feat/benchmark-integrity-realism, based on your current head e4ca2a4. Your Kubernetes reconciliation, PagerDuty fixtures/runbook changes, captured startup manifest, and capture script are preserved; I will not duplicate or rewrite those fixes. My work extends evaluator contracts/integrity, semantic evidence, task/profile materialization, and result compatibility. Shared grading/world interfaces will be extended from this pinned base, and tasks/ will only be regenerated from sources. Please flag any further changes planned in those shared interfaces so we can avoid overlapping edits. I will recheck your head before integration; no changes are being pushed to this PR or main.

[LukasParke]

Coordination update only; no new implementation request. The global clock refinement on feat/benchmark-integrity-realism now defaults scored worlds to a fixed business reference time, with transport ticking retained only as an explicit legacy condition. This requires one mechanical assertion update in crates/services/kubernetes/tests/kubernetes.rs: creationTimestamp 2026-11-03T08:40:07Z becomes 2026-11-03T08:40:00Z. I will make only that test-expectation change on my isolated branch; your Kubernetes production/reconciliation code, fixtures, startup capture, and checkout-saturation scenario remain unchanged. Main and this PR are not being modified or pushed. Your head was rechecked and is still e4ca2a4.
