v1.6.1

Changes

• Validate the development stack against Pi 0.99.1 and pi-subagents 0.73.1, including package loading, detached workers and native terminal proofs. The newer subagent runtime fixes async recovery, prompt-cache retention and a shutdown race.
• Reject private Pi SDK, TUI and TypeBox dependencies during packaging; add regression checks for host-module warnings. Existing plan-exec host dependencies remain wildcard peers. Warnings from other installed extensions require fixes in those packages.
• Correct setup commands and installation docs to use released runtimes without Git pins. Limit optional pi-tasks compatibility to the adapter's supported 0.9.x range.
• Publish GitHub release notes from this changelog with the version tag as the title.

Known limits

• Strict Fusion review and released Revmux still lack required ownership/lifetime contracts. Native child execution is not guaranteed to be unbounded.
• Dependency audit findings remain unresolved; the suggested force fix downgrades below the required terminal-proof baseline. See upstream audit.
