## Decision

Proposed for maintainer adoption with [#719](https://github.com/openpi-dev/openpi/pull/719):
OpenPI maintains the host compatibility checks introduced in [#719](https://github.com/openpi-dev/openpi/pull/719).

- Keep Pi packages host-owned peers. Preserve the current open-ended peer range;
do not bundle a second Pi runtime or add an OpenPI runtime version-rejection gate.

2026-11-03 integration note: rebased onto main `0addb739`. Renumbered this
proposal to 0006 because main adopted an unrelated Decision 0005. Its status
remains **proposed**; the existing frozen tool surface decision is unchanged.

2026-11-14 adoption proposal for [#328](https://github.com/openpi-dev/openpi/issues/328).
This amendment takes effect when maintainers merge it. The minimum, locked and
latest checks are already required on main. At
`ffc9c62475d8a1f87fcab7d511e8bf6badbccd82`, the published minimum is Pi
0.99.1 and the frozen development host is 1.2.0. The
[November 9 CI run](https://github.com/openpi-dev/openpi/actions/runs/42641377991)
passed the checks, Node suite and four installation smokes on both the minimum
and the then-latest Pi 1.5.0.

On November 14, a separate macOS smoke on Node 26.12.0 verified all eight
packages of the npm stable Pi 1.5.2 host. An isolated `pi list` reported the
packed OpenPI as its sole source. Offline RPC loaded the extensions, and the
packed Web CLI served its HTML, JavaScript, CSS and favicon using a separate
Pi installation. Full-suite evidence for 1.5.2 belongs to the next endpoint CI
run that selects that version.
