The --effort flag is now passed to subprocesses (e.g. headless subagent spawns) only when all three model launch flags — Opus 4.7, Opus 4.8, and Fable 5 — have been acknowledged by the user (unpinOpus47LaunchEffort, unpinOpus48LaunchEffort, unpinFable5LaunchEffort all true). Previously only Opus 4.7 and Opus 4.8 were required.
Evidence
Conditional effort passthrough (search for "unpinFable5LaunchEffort")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
