Capability half: what an operator can do now that they could not on 2026-08-20. The harness became drivable from editors (ACP) and scripts (headless NDJSON), gained a remote-workspace mode, and gained a subagent depth limit by default.
Channel: preview-or-beta. Half: capability. Date: 2026-08-27 to 2026-09-17.
Operator consequence: Try ACP and headless NDJSON on the rc pin. Treat SSH remote workspace and Computer Use as alpha-only experiments. The product subagents still default to wrapper-owned non-interactive modes; check them in --dump-config after each upgrade, since the wrapped CLIs moved versions.
