Help wanted: verify a native Claude Code channel round trip in an isolated mailbox #2

Why

The new agent-free local demo exercises the mailbox with a manual consumer. It explicitly does not establish that a native Claude Code session loads the channel and performs work. We welcome an independent, reproducible native integration trial.

Bounded outcome

Use the reviewed source snapshot, including the protocol and shell corrections. Its automated platform checks do not establish native-channel acceptance.

Use a new mailbox/config directory, a loopback listener and synthetic message text. Read the channel setup in the README. Keep the token in its private file, never in prompts or public logs. Use your existing authorized client; retain native permission prompts and unrelated configuration.

Acceptance for a report

• Record source SHA, OS, Python and Claude Code versions plus channel/trust state.
• Show that the native session loads the channel, receives a synthetic request and produces a reply that the sender can read back. A manual reply is not native acceptance.
• Record IDs and observable transitions; distinguish send acknowledgement, claim and returned reply.
• Include one offline/not-armed or permission-blocked case and describe the actual result without converting it to success.
• Confirm shutdown and restore only the trial's configuration; publish a short sanitized protocol, results and untested surfaces.

Remote networking/TLS, vendor dot integration, model quality and universal delivery guarantees are outside this trial. If native access is unavailable, report the blocker rather than substituting a mock. Comment with your intended platform and approach before starting; fixes can follow any reproducible failure with focused tests.

Packaged starting point — 2026-10-26

Release v0.1.2 now provides a wheel, source archive, the standalone clients and SHA256SUMS. Its exact source is ffaeea5, including the reviewed fixes above and the release version metadata.

You can install that wheel in the trial's isolated virtual environment and use the tagged channel setup. The linked local walkthrough retains its older pinned rehearsal; it is not a new native result.

Maintainer checks installed the package and completed a manual synthetic CLI exchange on loopback on Linux and Windows, including a separately downloaded public wheel on Windows. Native Claude channel activation and the acceptance requested above remain unverified. The task remains open for a volunteer; nobody is assigned by this update.
