Drew T a2b0a6b98f tune(draw): opus up to 340 ins, not 150 - Fable for difficulty, not length (Drew)
Drew, 2026-09-02: "use opus mainly and only escalate the difficult ones to fable".
The S69 table that set the old 150 line actually puts opus's cliff at ~350:

    m1  opus  191-347 ins   10/15 MATCH   1,291 tok/matched-ins   <-- best measured
    m2  opus  347-670 ins    1/9  MATCH   7,158                   <-- the cliff

So 150 was handing opus's STRONGEST band to Fable. Fable is now reserved for >340
instructions and for arm_from_history's compiler-internal residual signal (§413) at any
size. On the current pool that moves three functions back to opus while two stay on
Fable because their history names a scheduling/regalloc residual - escalation by
difficulty rather than length, which is the point.

Retries default back to opus: one failure is not evidence of a wall, and the history
signal lifts a target on its own if the notes justify it.
