- Decision date: February 24, 2026
- Decision: `hold` (no cohort expansion yet)
- Rationale: Window A fails 3/4 numeric gates (p50 delta, p95 delta, fallback rate) with only 10 total routed turns, including two concrete fallback failure modes:
and Window C pre-probe baseline confirms missing guard-coverage evidence (`pi_no_tools_mode`, `capability_query`, `attachments_present` all at 0).
- `pi_module_interface`
- `empty_assistant_text`
Window B shows fallback recovery (0%) in a post-fallback slice but fails minimum sample thresholds and has no native baseline routes for delta-gate evaluation.
