Copilot was unable to run its full agentic suite in this review.

Adds a markdown “solution” file containing a proposed diff to extend the ACP client with session state + re-auth scaffolding and retry-on-401 behavior.

Changes:

• Adds onSessionExpired option and introduces client/session state plumbing (session, re-auth deferred, request queue).
• Adds initial re-authentication / retry flow (currently stubbed) and session cleanup helper logic.
• Documents these changes as an embedded diff in shanaboo_solution.md.

• The markdown file appears to end mid-line (and the embedded diff is truncated), which makes the document incomplete/unrenderable for review. Please include the full diff/content and ensure any opened code fences are properly closed so the file renders correctly.

```diff

shanaboo_solution.md:1

• The 401 branch performs (or waits for) re-auth, but then unconditionally fails with the original 401 error (Effect.fail(error ...)) and never retries the original effect. If the intent is ‘retry once after successful re-auth’, this should re-run effect after Deferred.await(...) (or return a different error when re-auth fails) rather than always failing.

```diff

shanaboo_solution.md:1

• Deferred.fail(deferred, err) is not yielded/returned, so the failure effect may never execute. This can leave waiters on Deferred.await(deferred) hanging indefinitely on the error path. Yield the effect (or otherwise ensure it runs) before failing.

```diff

shanaboo_solution.md:1

• Using (error as any).status defeats type safety and risks silently breaking if the error shape changes (e.g., statusCode vs status). Prefer narrowing on a known discriminant/shape (e.g., _tag + a typed status field on AcpProtocolError) rather than any.

```diff

shanaboo_solution.md:1

• Replacing requestQueue with a new unbounded queue during cleanup can strand any in-flight/queued requests: callers waiting on their deferred may never be completed. Consider draining the existing queue and failing each request’s deferred with a session-expired/auth error (and/or shutting down the old queue) before replacing it.

```diff

shanaboo_solution.md:1

• Effect.acquireRelease typically registers a finalizer to run when the surrounding scope closes; if this code isn’t running in a scoped region, cleanupSession may not run when you expect (e.g., it may be delayed until fiber/scope termination). If the goal is ‘always cleanup after re-auth attempt’, use an operator that guarantees immediate finalization for this effect (e.g., ensuring-style finalizers or acquire-use-release with an explicit use phase).

```diff

shanaboo_solution.md:1

• Introducing an exported AuthenticationError alongside AcpError.AuthenticationError (used later) is likely to confuse consumers and reviewers because the names collide conceptually. Consider renaming this local/internal error (e.g., InternalAuthenticationError) or eliminating it and failing with AcpError.AuthenticationError directly.
