Validation and limits
49 offline tests passed; four live tests were skipped by default. Fresh wheel
installation, plugin export, and isolated local marketplace installs were checked
for both harnesses. Prior live tests on macOS covered both directions, correlated
replies, and a busy Codex peer. Harness versions: Claude Code 2.1.286, Codex CLI
0.159.0, daemon 0.159.2.
Linux live delivery and restricted sandbox configurations are not validated.
Internal harness protocols can change. sent is transport acceptance, not proof
of reading. Identity observations are audit data, not cryptographic authentication.
Messages are stored locally and may also enter the receiving harness's model
provider and transcript. See data handling.
The GitHub marketplace is independently hosted. This release is not a claim of
approval or listing in either vendor's official directory. No PyPI publication.
