…appers (#970) ## Problem `server/herdr/client.ts` exported an untyped `herdrRpc(method: string, params: Record<string, unknown>)`. Eleven server files called it directly for four methods (`pane.process_info` x10, `agent.get` x6, `pane.send_text` x2, `pane.send_keys` x1), each with its own inline result type. Nothing stopped `{ target }` reaching `pane.process_info`, which herdr then silently answers for the focused pane (the AGENTS.md rule was prose only). ## Change - `server/herdr/methods.ts`: `HerdrMethods`, a `{ [method]: { params; result } }` map for those four methods. Params and result bodies come from the generated schema types; `PaneProcessInfoParams`, `AgentTarget` and `PaneProcessInfo` are now generator roots (`scripts/generate-protocol-types.ts`, regenerated `shared/herdr-api.generated.ts`). The map itself is hand-written because herdr's schema links a method to its params (`request.oneOf`) but not to its answer: answers are one `ResponseResult.oneOf` told apart only by a `type` tag (`pane_process_info`, `agent_info`, `ok`). - `herdrRpc<M extends keyof HerdrMethods>(method, params: HerdrMethods[M]["params"], …): Promise<HerdrMethods[M]["result"]>` is the first overload. An untyped fallback overload stays for methods the map does not list yet. It refuses a typed method name (`UntypedHerdrMethod<M>` is `never` for one), so `herdrRpc("pane.process_info", { target })` is a compile error. `server/herdr/seam.test.ts` pins that with `@ts-expect-error` and checks the wire params of the new wrappers against a stand-in socket. - New wrappers: `paneProcessInfo(paneId)` returns one shared `ProcessInfo` (= generated `PaneProcessInfo`: shell_pid, foreground_processes with pid/name/argv0/argv) and `agentGet(paneId)` returns `AgentInfo`. The existing `paneSendText` / `paneSendKeys` now go through the typed overload. The wrappers call the exported `herdrRpc` binding, so tests that `spyOn(herdr, "herdrRpc")` keep working. - Migrated (no open PR touches them): `server/pi.ts`, `server/omp.ts`, `server/grok-store.ts`, `server/agy-store.ts`, `server/codex.ts` (x3). Behaviour is unchanged: the same params go on the wire, with the same default timeout and the same `.catch` / `try` at each call site. `codex.ts` keeps its old `argv?: string[]` reading through a commented cast, because the schema allows `argv: null` and that path has never handled null. Changing that would change behaviour, so it is left for a separate fix. - Guard: `server/conventions.test.ts` ("herdr socket") now fails when server code outside `server/herdr/` uses `herdrRpc`. The message names the fix ("add a typed wrapper in server/herdr/client.ts; for pane status use the server/collector.ts listeners") and the allowlist `HERDR_RPC_ALLOWED`. A stale allowlist entry also fails. The `events.subscribe` / `subscribeEvents` rules from #949 were already there; their message now also says where `events.subscribe` lives. - AGENTS.md: the `pane.process_info` line points at `paneProcessInfo` / `HerdrMethods` and names the enforcing test. Only that one line changes; #812, #888 and #894 also edit AGENTS.md. ## Allowlist (`HERDR_RPC_ALLOWED`, migrated in PR B) | File | Open PRs touching it | |------|----------------------| | `server/conversation.ts` | #869 #912 #923 | | `server/gjc-runtime.ts` | #912 | | `server/hermes.ts` | #910 | | `server/omo.ts` | #923 | | `server/shell-agent.ts` | #885 #923 | Built from `gh pr list --state open --limit 100 --json number,files` on 2026-10-14. ## Known limits (closed in PR B) - The export is still named `herdrRpc`. Renaming it to `herdrRpcUnsafe` would touch about 33 test files and 30 `scripts/` harnesses, several of them in open PRs (api.contract, gjc.contract, omo.contract, ui-regression, pending-input…). Tests and `scripts/` QA harnesses are outside this guard's scope: they drive herdr (`pane.report_agent`, `workspace.create`, …) and are not part of the bridge seam. - A call with an explicit result type, `herdrRpc<Inline>("pane.process_info", …)`, still reaches the untyped fallback. That is the form the allowlisted files use, and they may not change here. In server code the source guard closes this gap. The fallback goes away once the allowlist is empty. ## Validation - `bun run check fast`: green. A first run had one failure in `server/portal.test.ts` ("does not treat an arbitrary interpreter as a Portal script": the process argv read raced and returned undefined). This change does not touch that file, it passed alone, and the rerun was fully green. - `bun run test:integration`: 455 pass, 0 fail, 14 skip in 38 files (includes the omp, codex, codex-binding, pi, gjc, omo and hermes contract tests). - I checked by hand that the guard fails on a new `herdr.herdrRpc` use in `server/pi.ts`. ## Follow-up: PR B Once #869, #885, #910, #912 and #923 land: migrate the five allowlisted files to `paneProcessInfo` / `agentGet` / `paneSendText` / `paneSendKeys`, empty `HERDR_RPC_ALLOWED`, drop the untyped fallback overload (or rename it `herdrRpcUnsafe` for tests and scripts), and consider handling `argv: null` in `codex.ts`. ## Review Fixed in 290d5f1: - **Union of typed methods (medium, part of finding 1).** The typed overload takes `SingleHerdrMethod<M>`, so `herdrRpc(cond ? "pane.process_info" as const : "agent.get" as const, { target })` no longer compiles. `seam.test.ts` pins this with a `@ts-expect-error` line. Checked with tsc: the inferred `herdrRpc("pane.process_info", { pane_id })` still returns the typed result. - **Allowlist missed #928 and #859 (medium).** `conventions.test.ts` adds `HERDR_RPC_PENDING` with `server/gjc-status.ts` (#928) and `server/index.ts` (#859). Those PRs add a `pane.process_info` call, but neither file calls herdrRpc on main yet, so the "no longer calls" check skips them. It would be better for both PRs to switch to `paneProcessInfo(paneId)`, which is a one-line change in each. After that, these entries come out. - **Docs claimed more than the PR delivers (low).** AGENTS.md now says the guard enforces the rule, not the compiler, and that the allowlisted and pending files still call herdrRpc. The changelog fragment now says "no longer compiles without an explicit result type". "PR B" is replaced with "a follow-up PR that moves these files to the wrappers once their open PRs land". The fallback docblock in `client.ts` and the `UntypedHerdrMethod` comment in `methods.ts` list the holes. Deferred to the follow-up PR that drains `HERDR_RPC_ALLOWED`: - **Explicit result type and widened string (rest of finding 1).** `herdrRpc<T>("pane.process_info", { target })` and `herdrRpc(m as string, { target })` still compile. With an explicit T, the fallback's `M` stays at `string`, and that cannot be closed while the fallback shares the name. Closing it means splitting the fallback out as `herdrRpcUntyped` (or `herdrRpcUnsafe`) and moving about 400 test and script call sites onto it. It also means converting the `herdrRpc<T>("pane.process_info" | "agent.get", …)` calls in the five allowlisted files, which conflicts with their open PRs. `seam.test.ts` keeps both forms as compiling lines with a comment, so the follow-up can turn them into `@ts-expect-error`. - **Error message.** Two overloads are still present, so tsc reports a bad inferred call such as `{ target }` to pane.process_info as `not assignable to parameter of type 'never'` instead of naming the wrong param. That message only gets better with the split. - **Stale pending entries.** Nothing removes a `HERDR_RPC_PENDING` entry on its own. If #928 or #859 switches to `paneProcessInfo` or closes, its entry stays until someone takes it out by hand. - **Tell the open PRs.** #912, #923, #928, #859 and #910 call `herdrRpc<T>("pane.process_info", …)`. They should hear about the switch to `paneProcessInfo` before the split lands. I have not commented on those PRs. Checks: `bun run check fast` passed (typecheck, build, 3452 unit tests). `bun run test:integration` passed (455 pass, 0 fail). 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

## Change Fix the intermittent `server/omo.contract.test.ts:52` failure in “labels a running omo pane when herdr supplies no agent kind”. ## Root cause and evidence The fixture waits for its script path in one herdr `pane.process_info` response, but `labelOmoPanes` performs a separate fresh process probe. The fixture marker is not a readiness barrier for that probe: a missing matching foreground process or a failed probe leaves the original snapshot's agent undefined. The test asserted the first label sample immediately instead of waiting for the state it describes. Main run 38555205694 on October 14, 2026 failed after 199.60 ms: expected `"omo"`, received `undefined` at line 52:77. Five local pre-fix isolated runs passed, including an attempted concurrent unit-suite load, so the failure remained intermittent locally. The CI log and the two independent process probes establish the synchronization gap without guessing which negative-probe branch occurred. Open PRs #984 and #985 do not touch this test. PR #923 changes custom OmO runtime recognition but leaves this one-shot assertion unchanged, so this is not a duplicate. ## Fix Poll the exact labeled state with a bounded five-second deadline and 50 ms interval. The same original snapshot is retained, so all three existing assertions still prove that herdr supplied no agent kind, the derived snapshot is labeled `omo`, and the input snapshot is not mutated. No assertion retry, timeout increase, fixed sleep, production change, or changelog entry. ## Verification - Five consecutive isolated contract runs passed on one unchanged source fingerprint: `CHECK_WAIT_SECONDS=3600 bun run check run bash -c 'for i in 1 2 3 4 5; do bun test --timeout 15000 ./server/omo.contract.test.ts || exit 1; done'`. Report: `23297fbe-e853-45cf-ad71-a4c6990b77e0`. - `bun run check fast` passed on the same source fingerprint. Generated types, typecheck, build, and unit tests all passed: 3,574 passed, 50 skipped, 0 failed. Report: `19778f35-f21d-4c74-987e-9c48ae6620a9`. - `git diff --check` passed. Toolchain: Bun 1.4.2, Node 22.23.1, herdr 0.9.3, macOS arm64.

## Change GJC can finish its parent turn while herdr still reports `working` from a provider child. The Web UI now derives GJC turn status from the transcript bound to its native runtime, independently of the selected provider or preset. The shared transcript tracker keeps OMO defaults and adds GJC-specific lifecycle rules: native work and runtime notifications produce RUN, final answers settle the turn, `ask` waits for input, and errors or interrupted processes remain READY. Missing evidence falls back to herdr, and restored bindings publish their current status over WebSocket. Transcript discovery uses the foreground cwd and native process start information, including the Windows process lookup. Native OMO ownership takes precedence over a provider-child GJC label in snapshot reads, periodic discovery, callbacks and status events. Native ownership disappearing allows standalone GJC to take over again. This corrects parent-turn status. It does not infer live background-job counts from historical records; GJC maintains that live job state in memory. No HTTP/WS wire fields, launchers, authentication or model presets change. ## Validation - Bun 1.4.2, herdr 0.9.3, Linux. - `bun run check fast`: 3,019 passed, 0 failed, 8 skipped; workflow syntax, generated types, application/tool typechecks and build passed. - Combined with PR #923 in a separate worktree, the raw-GJC/native-OMO ownership fixture failed before the fix and passed afterward (13 assertions, including a periodic refresh). - Isolated native GJC + OMO binding contracts: 17 passed, 62 assertions. - `bun run check run --build` (native contracts followed by `bun scripts/gjc-status-browser-regression.ts`): six real Chromium scenarios passed using owned panes, a real server, HTTP snapshots and WebSocket status frames: completed history, native work, final completion despite stale raw reports, background-result wake, user questions, and delayed transcript readiness. - Read-only verification distinguished a real GJC session's completed historical turn from its subsequently resumed live work. Existing user sessions were not changed. - Windows process discovery is covered by injected tests; a live Windows browser was not exercised.

Change
A custom Bun launcher can run the OMO engine normally while herdr reports it as
piand its argv contains no standard OMO executable. The chat lens then misses the native conversation.Recognize custom runtimes from their OMO store and native holder records, validating the live PID, process start and cwd. Keep each holder's store/session identity through pending, malformed and ambiguous transcript cases. Reuse the same identity in snapshot discovery, chat routing and shell-start confirmation; verified OMO ownership takes precedence over a child agent's label. Preserve standard and hoisted-engine launch compatibility without matching custom filenames, profiles or model names.
Custom recognition needs readable process metadata and a native holder in an explicit OMO store or the default OMO store. Insufficient evidence fails closed. This does not change launchers, model mappings or authentication.
Validation
bun run check fast— generated types, both TypeScript checks, production build, and unit suite pass (2,996 passed, 8 skipped)./new, live first-message rendering and resume.A running custom OMO pane was inspected read-only: the original PID remained active, runtime detection succeeded, and the native transcript parser returned its conversation. All reproduction inputs and browser captures use isolated synthetic panes. No deployment or merge was performed.
The related GJC status PR #928 was also checked in an isolated combined worktree: native OMO ownership survives a raw GJC label at initial snapshot and after periodic refresh.
