Hi @ogulcancelik, the intake gate closed this approved feature PR after the follow-up schema commit. Could you reopen it to grant the PR-specific scope override? This is the Jcode integration you invited in Discussion #1848: #1848 (reply in thread) |

4149-4174: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick winConsider bounding the socket accept/join and the output-polling window.
Two robustness concerns in this new end-to-end test:
- The polling loop waits at most 1 second (100 × 10ms) for
previous_outputto appear before asserting its contents. Under a loaded CI runner, this window can be too short, causing an intermittent, hard-to-diagnose failure rather than a clear one.- The spawned server thread calls
listener.accept()with no timeout, andserver.join()later waits on it unconditionally. If the hook script fails to connect to the socket for any reason (a regression in the hook, environment issue, etc.), this test hangs indefinitely instead of failing with a clear timeout error.Consider widening the polling budget and adding a bounded wait around the
accept()/join()(for example, a channel-basedrecv_timeoutguard) so a broken hook produces a clear test failure instead of a stalled CI job.

hey jeremy, thanks for the pr. the detection part looks good, but the session restore hook has a problem. jcode runs hooks from its shared server, so they use the server’s original herdr pane id. the first pane may work, but later panes can report their session to the wrong pane. if the server started outside herdr, they report nothing. the current test does not cover this. existing hooks are also run differently after installation: jcode normally runs them directly, but this adapter uses could we fix these in jcode first and test two panes using the same server? native support for multiple hooks would make the herdr integration much safer. |

@coderabbitai review Please review the current head fcd92f4. The follow-up adds Japanese/Chinese documentation parity and clarifies the saved-transcript requirement. Local full CI passes (3646 tests, 6 skipped), and the hosted distribution contract now passes. The existing timeout/source-assertion thread is resolved. @greptile-apps please also refresh the review of the current head, as the visible summary still references the August commit. |

@greptile-apps please refresh the review on 68c3a4f. This addresses all three new review findings: reject malformed top-level hooks before uninstall mutation, keep Unix hook permissions at 0600 with interpreter-based invocation, and scope pending Jcode resume invalidation to Jcode reports. Added regressions pass with the full suite (3649 tests, 6 skipped). Real CLI malformed-config/mode checks and actual Jcode multi-pane, clear, native resume, and persisted cold restore passed again.

Ready for maintainer re-review at 68c3a4f. All final-head checks pass: Linux (3649 tests), macOS (3435), Windows (3153), Nix, ConPTY packaging and distribution/docs. Both review bots completed on this head. The three valid CodeRabbit findings are fixed and tested; the remaining module-gating comment is already covered by the enclosing test-crate cfg, explained inline with the green Windows job. Actual installed Jcode was also rechecked through two-pane start/prompt, isolated /clear, native --resume and Herdr restart restoring three saved conversations. The PR description includes validation scope and the empty-unsaved-session limitation. @ogulcancelik the requested master refresh is complete and GitHub reports no merge conflicts. Please re-review when convenient. Jcode #758 is already merged, so the old needs-upstream-fix label appears stale. @rameshbaskaran the current PR head is ready for the independent setup verification you offered. Thanks again @przeqpiciel for the conflict-resolution work. |
