+(preflight → find-weakness-and-act) via interactive tmux Claude session
+(sonnet). Finds the project's biggest weakness, challenges planner claims,
+and generates evidence through explore/exploit decisions:
 
-1. **Health signals** — CI pipeline trends (Woodpecker), stale issues, agent
-   health (tmux sessions + logs), resource patterns (RAM, disk, load, containers)
-2. **Outcome signals** — output freshness (formula journals/artifacts), capacity
-   utilization (idle agents vs dispatchable backlog), throughput (closed issues,
-   merged PRs, churn detection)
-3. **External signals** — dependency security advisories, upstream breaking
-   changes, deprecation notices, ecosystem shifts (via targeted web search)
+- **Explore** (low confidence) — file a `prediction/unreviewed` issue for
+  the planner to triage
+- **Exploit** (high confidence) — file a prediction AND dispatch a formula
+  via an `action` issue to generate evidence before the planner even runs
 
-Files up to 5 `prediction/unreviewed` issues for the Planner to triage.
-Predictions cover both "things going wrong" and "opportunities being missed".
-The predictor MUST NOT emit feature work — only observations about health,
-outcomes, and external risks/opportunities.
+The predictor's own prediction history (open + closed issues) serves as its
+memory — it reviews what was actioned, dismissed, or deferred to decide where
+to focus next. No hardcoded signal categories; Claude decides where to look
+based on available data: prerequisite tree, evidence directories, VISION.md,
+RESOURCES.md, open issues, agent logs, and external signals (via web search).
+
+Files up to 5 actions per run (predictions + dispatches combined). Each
+exploit counts as 2 (prediction + action dispatch). The predictor MUST NOT
+emit feature work — only observations challenging claims, exposing gaps,
+and surfacing risks.
