69 * Controls the Phase 4 "Final Plan" bullets in the 5-phase plan mode
70 * workflow (messages.ts getPlanPhase4Section). 5-phase is 99% of plan
71 * traffic; interview-phase (ants) is untouched as a reference population.
72 *
73 * Arms: null (control), 'trim', 'cut', 'cap' — progressively stricter
74 * guidance on plan file size.
75 *
76 * Baseline (control, 14d ending 2026-03-02, N=26.3M):
77 * p50 4,906 chars | p90 11,617 | mean 6,207 | 82% Opus 4.6
78 * Reject rate monotonic with size: 20% at <2K → 50% at 20K+
79 *
80 * Primary: session-level Avg Cost (fact__201omjcij85f) — Opus output is
81 * 5× input price so cost is an output-weighted proxy. planLengthChars
82 * on tengu_plan_exit is the mechanism but NOT the goal — the cap arm
83 * could shrink the plan file while increasing total output via
84 * write→count→edit cycles.
85 * Guardrail: feedback-bad rate, requests/session (too-thin plans →
86 * more implementation iterations), tool error rate
