Not sonnet, and not variant. Swept models through the new pipeline: every -free model runs,
every paid one silently does not — haiku, sonnet and codex-mini all never start.
Ruled out: variant (sonnet advertises low/medium/high/max and echoes back an invalid
"default", which looked like the answer and was not — setting high explicitly also never
ran); credentials (zen key in auth.json plus ANTHROPIC_API_KEY); and the sidecar environment,
since the same process runs sonnet fine through opencode run.
So the new pipeline does not resolve paid-model credentials and says nothing, while run and
the legacy path authenticate fine. Upstream bug in an in-progress pipeline, not our config.
The fork stays blocked, but precisely: steer and queue are proven, and the day a paid model
runs there the migration is worth doing immediately. Re-run the sweep after each upgrade.
