Good first issue: v0.24.1 protocol/client interoperability

[qh-work]

v0.24 contribution: prove the protocol and authorized client interoperate

The target is now v0.24.1,
not the old v0.21 Host Adapter envelope or an unqualified main checkout. The
protected main branch may still be v0.23. Earlier discussion is historical;
please base new work on the version tag and keep this contribution small.

The release provides one open memory protocol and two equal usage paths: an
independent implementation using its host's existing tools, and an optional
user-authorized plugin. An independent implementation does not need Python or
SQLite; canonical record bytes and exchange semantics must agree.

Small first contribution

1. Use the published synthetic NDJSON exchange and known-answer hashes to
   explain one complete import/recall/export round trip through your chosen
   implementation. Do not require a vendor account, network service or plugin.
2. Add an optional authorized-client round trip: import those same records via
   the configured protocol entry, inspect them through MCP, then export them.
   Unsigned imports must remain quarantined until explicitly accepted. Compare
   canonical IDs, hashes, provenance and relations, not database file bytes.
3. Document the exact commands, interpreter/host versions and observed results.
   An unexecuted recipe is useful, but label it unexecuted rather than passing.

The broader lifecycle review is a separate follow-up, not a prerequisite for
the first small contribution: capabilities, session.open, turn.input,
turn.commit, turn.abort and session.close use the new
universal-memory-lifecycle-request/v1 envelope. Check exact retries, crash
boundaries, capture opt-in and historical receipts without asserting v0.21 wire
compatibility. Closing a session must not remove long-term memory.

The maintainer did not run application tests for this release. These are
independent review tasks to perform only with your own host/user authorization.
Do not use real memories, prompts, credentials, account identifiers, native
session IDs, private databases or local user paths in published fixtures.
AI-assisted contributions are welcome when the author can explain and reproduce
the result. Memory never grants instruction, policy or execution authority.

Hi @qh-work, I’d like to work on this issue. I’ve reviewed the contribution and privacy guidelines, and I plan to add a documented five-minute smoke test using only the public schemas, generic stdio adapter, fake Vault, and synthetic fixtures. I’ll cover the required protocol lifecycle, verify the negative-authority fields and local-only behavior, and include the exact tests and results in the PR. Could you please assign this issue to me?

Hi @jagadeepmamidi, thank you for offering to help and for reviewing the contribution and privacy guidelines — I really appreciate it!

We've now published v0.24.1, bringing together two routes to the same task-independent persistent memory contract:

• An authorized full client/plugin with MCP, host adapters, signed incremental sync, diagnostics, and backup/restore.
• An independent lightweight protocol that other models and agents can implement using their existing tools, without installing our plugin.

I'd love for you to try the updated release: AI implementer quick start. Your proposed five-minute smoke check is still very welcome; this issue now focuses on protocol/client interoperability using synthetic fixtures.

Please use the v0.24.1 tag or release downloads, rather than an unqualified main checkout — protected main has not yet caught up. This release has undergone static and package checks, but has not been runtime-tested; independent verification would be especially valuable. Please use temporary storage and synthetic data, and include the exact version, host/runtime, and observed results in any feedback or PR.

Thanks again for your interest and willingness to contribute!
