The next feature slice out of server/index.ts and shared/protocol.ts, after integrations (#1686) and plugins (#1687): the background tasks route and its types move into their own files. Behaviour, path, status codes and messages stay the same. The plan is .omo/plans/feature-slices-plan.md in the maintainer's workspace.

The agent catalog slice is on hold: the open PR #1597 changes the same /api/agents branch, and the refactor brief says the bug fix goes first, then the move.

This PR moves responsibility, so it is not move-only.

Three commits: the check first, then the move, then the branch the move made testable

1. test(server): pin GET /api/pane/omo-tasks before it moves adds server/tasks-routes.test.ts. The existing route coverage is live only: api.contract.test.ts checks the missing pane and an unknown pane, and claude-session.contract.test.ts checks a Claude Code pane's subagents. The parsers have unit tests (omo-tasks.test.ts, claude-subagents.test.ts). The new test runs the route itself in the unit lane without herdr: a real createServer({ port: 0, hostname: "127.0.0.1", stateDir: mkdtempSync(…), … }) with paneGet stubbed through spyOn(herdr, "paneGet"). It pins:

   • a POST answers 400 method_not_allowed, and a request without pane_id answers 400 missing_pane_id;
   • a pane that runs neither OmO nor Claude Code answers 200 with no tasks, no runs and a valid server_time, after asking herdr for that pane;
   • when herdr does not answer that pane lookup, the route still answers 200 with what it knows, once its 1-second bound (within(1000, …)) runs out. That makes this test take about a second.

   On unchanged code it gives 3 pass, 0 fail.

2. refactor(server): move the background tasks route and types into their own slice

   • Moved: the branch, unchanged, into handleTasksRequest(request, url, pathname, { omo, claudeAgents }): Promise<Response | null> in the new server/tasks-routes.ts. This is the nullable route pattern of the earlier slices.
   • The trackers stay the core's: index.ts passes the core's own omo (OmoStatus) and claudeAgents (ClaudeSubagentStatus). The route's type allows only the methods it calls (sessionOf, and ensure on the Claude tracker), and it constructs nothing, so there is one tracker each as before and startup order does not change.
   • Moved: OmoTask, OmoRunNode, OmoRun and OmoActivity, verbatim with their doc comments, into the new shared/tasks.ts. It holds types only. OmoTaskResult stays in protocol.ts, because it is conversation data.
   • Stays in index.ts: one call at the same place in the dispatch order, after the pane routes and before /api/pane/plan. The now-unused processAlive, omoTasks, omoRuns and claudeSubagents imports leave. within stays, because the plan route still uses it.
   • Stays in protocol.ts: a type re-export of the four names, so server/omo-tasks.ts, server/claude-subagents.ts, server/claude-session.contract.test.ts, src/lib/api.ts, src/lib/omoTasks.ts and its test, and BackgroundTasks.tsx compile unchanged.
   • Also in this commit: as the CI session asked after refactor(server): move the plugin routes and types into their own slice #1687, the comment on createServer's pluginActionWaitMs option now says PLUGIN_ACTION_WAIT_MS lives in server/plugin-routes.ts.

3. test(server): cover the OmO branch of the tasks route, added after CodeRabbit's nitpick. handleTasksRequest now takes the trackers as an argument, so the unit lane can call it with a fake OmO tracker that names a session. The session's task record comes back as its task, the Claude tracker is not asked, and another path is not this route's.

Rebased onto main after PR #1597 (86e0643) merged: the one conflict was the import block in server/index.ts, where PR #1597 renamed the shell-agent.ts import; both changes are kept.

Checks

• After the move: HERDR_TEST_MODE=unit bun test server/tasks-routes.test.ts server/omo-tasks.test.ts server/claude-subagents.test.ts src/lib/omoTasks.test.ts server/plugin-routes.test.ts server/shell-agent.test.ts gives 127 pass, 0 fail (with the third commit). The pinning test's three cases are unchanged by the move.
• --color-moved on the move commit: git diff --color-moved=plain --color-moved-ws=allow-indentation-change HEAD~2 HEAD~1 -- server shared shows 143 lines as moved: the branch (one indent level shallower in its new file), the omo-tasks.ts import that moved with it, and the four types. The 23 other lines are:
  • in index.ts: 4 import lines, the pluginActionWaitMs comment (before and after), and the 2-line call;
  • in the new route file: its 5-line header, 4 imports, the TaskTrackers type with its comment, the function's doc comment and signature, and return null;
  • in protocol.ts: the re-export line.
• Client imports: bun run typecheck passes on both tsconfigs. No file in src/ or site/ imports shared/tasks.ts. shared/tasks.ts has no import and no value export.
• Sizes: server/index.ts goes from 785 to 763 lines and shared/protocol.ts from 1,452 to 1,410. The new modules are 41 and 43 lines.
• Risks checked:
  • Import cycles: none new. The route imports claude-subagents.ts, herdr/client.ts, http.ts, omo-status.ts and omo-tasks.ts, none of which reaches index.ts. It imports nothing from core/, so the core ownership rule (core/ownership.test.ts) holds.
  • Initialization order: unchanged. The route only reads the trackers it is given.
• bun run check fast (on the rebased branch): passes (unit 6151 pass, 0 fail, 12 skip in 437 files, 8 at a time, 57.6s).
• CI's integration lane runs the api.contract.test.ts and claude-session.contract.test.ts cases against an isolated live herdr.

Overlapping open PRs

The open PRs that touch these files (#1598 and #1442 in index.ts and protocol.ts, #1652 and #1427 in protocol.ts) do not change the moved lines or these types. The open PR #1597, which edits index.ts, does not touch them either.

📝 Summary

Summary by CodeRabbit

• Bug Fixes
  • Task requests now return consistent responses when a pane or agent session cannot be found, including empty task and run lists with a server timestamp.
  • Requests using an unsupported method or missing a pane ID receive clear error responses.
  • Claude subagent tasks are returned when available, including after a brief attempt to discover the agent session.

The server now delegates /api/pane/omo-tasks requests to a dedicated handler. Shared task and workflow interfaces define the response data. Tests cover request validation and unavailable panes.

Changes: Task route

Layer / File(s)	Summary
Task response contracts shared/tasks.ts, shared/protocol.ts	The shared task module now defines task, workflow node, workflow run, and activity response interfaces. shared/protocol.ts re-exports the four OmO types.
Task route handling and integration server/tasks-routes.ts, server/index.ts, server/tasks-routes.test.ts	The new handler validates the method and pane_id, returns OmO tasks and runs or Claude subagents, and includes server_time. The server delegates matching requests to the handler. Tests cover invalid requests, missing panes, and lookup timeouts. The plugin wait-time comment now identifies its source file.

Add a populated OmO route test.

The route tests cover only fallback responses. A regression that makes handleTasksRequest skip the omo.sessionOf(paneId) !== null branch and return empty tasks and runs could pass these tests. Add a positive-path assertion that uses the core-owned OmO tracker and verifies the endpoint returns the populated task and run data.

On CodeRabbit's nitpick (a populated OmO case in server/tasks-routes.test.ts): not added in this PR, to keep it to one push.

• The OmO branch is moved unchanged (the --color-moved summary above shows it as moved lines). Its two readers are covered by server/omo-tasks.test.ts (omoTasks, omoRuns on fixture records), and the Claude Code branch by server/claude-session.contract.test.ts in the integration lane.
• What is not pinned in the unit lane is the dispatch into that branch. Since this PR, handleTasksRequest takes the trackers as an argument, so that test is now easy to write: call the handler with a fake omo.sessionOf that points at a fixture task record and assert the populated tasks and runs. I can add it as a follow-up test-only PR, or as a commit here if the reviewer prefers it in this one.

Rebased onto main after PR #1597 (86e0643) merged, which had left this PR conflicting. The only conflict was the server/index.ts import block, where PR #1597 changed the shell-agent.ts import; both changes are kept. Since this push was needed anyway, it also carries the populated OmO test from my earlier comment as a third, test-only commit (de8c609f). The body's checks are updated. bun run check fast passes on the new head.

Merge-pass review. CodeRabbit reviewed 09e811f with no actionable comments and skipped de8c609. A code-review agent reviewed de8c609 and stands in for it, per AGENTS.md: APPROVE, CLEAR.

• Rebase: the PR now sits on main 86e0643 (fix(agents): share bounded login PATH discovery with shell launch #1597). range-diff shows the move commit changed only one import context line. Commit 3 is test-only.
• Behaviour is identical.
  • The moved branch and main's version are the same 23 lines with whitespace ignored. The four types match shared/tasks.ts exactly.
  • In --color-moved, the only lines not shown as moved are the imports, the two-line call, the new file's header and signature, return null and the re-export.
  • The call sits after every gate (server/index.ts:590), and pane/omo-tasks is still in the machine proxy list.
• No state moved and no import cycle. startup-order.test.ts passes.
• The tests can fail. 17 of 19 mutations fail a test.
  • Two OmO-branch mutations survive: emptying runs and dropping server_time. The fixture has no dag_*.json and the test does not read server_time on that path.
  • This does not block, because the moved code is byte-identical to main's. A test-only follow-up will pin both.
• Type-only re-export: bun run typecheck passes.
• Tests: 164 related unit tests pass. The contract tests (api.contract.test.ts:1710, claude-session.contract.test.ts:188/284) pass on an isolated herdr.
• No closing keywords before another PR number in the title, body or commits.
