The last inline feature slice out of server/index.ts and shared/protocol.ts, after integrations (#1686), plugins (#1687), background tasks (#1688), the agent catalog (#1690) and plans (#1694): the file routes and their types move into their own files. Behaviour, paths, status codes, headers and messages stay the same. The plan is .omo/plans/feature-slices-plan.md in the maintainer's workspace.

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

Two commits: the check first, then the move

1. test(server): pin the file routes before they move adds server/file-routes.test.ts.

   • Why it is needed: the existing route coverage is mostly live: page-media.contract.test.ts, route-envelope.contract.test.ts and device-access.contract.test.ts. The helpers have unit tests (file-view.test.ts, project-favicon.test.ts, files.test.ts). In the unit lane, only open-access.test.ts reaches a file route, and only for the watching-device refusal.
   • How it runs without herdr, in the unit lane: a real createServer({ port: 0, hostname: "127.0.0.1", stateDir: mkdtempSync(…), … }) reading a temp project folder, with paneGet stubbed through spyOn(herdr, "paneGet") where a pane is involved.
   • What it pins:
     • Methods and other sites:
       • a POST answers 400 method_not_allowed, and HEAD is allowed;
       • another site's no-cors read answers 403 cross_site, while a top-level navigation is served.
     • A file by its absolute path:
       • /api/fs/stat answers its name, kind and size;
       • /api/fs/file answers its bytes, inline by default and attachment with download=1;
       • a missing file answers 404 not_found.
     • A relative path in a pane's folder: with pane_id, a relative path is found in the folder herdr reports for that pane. When herdr cannot say that folder, the relative path is 404 not_found, but an absolute path is still served.
     • The project icon: /api/fs/favicon without root answers 400 missing_root. A folder with public/favicon.ico answers that icon, and a folder without one answers { icon: null }.
     • Page media: an address never given out answers 404 not_found, and a POST answers 400 method_not_allowed.

   On unchanged code it gives 5 pass, 0 fail.

2. refactor(server): move the file routes and types into their own slice

   • Moved: both branches, unchanged, into handleFileRequest(request, url, pathname, requester): Promise<Response | null> in the new server/file-routes.ts:
     • /api/fs/stat, /api/fs/file and /api/fs/favicon;
     • /api/fs/page-media/:media_id.
   • Moved with them: claudeTempFolder, which only the file read used.
   • Who asks: the access gate in index.ts already worked out who asks: bridgeAuthorized, requestHost, forwarded, client and access. The route gets those values as they are (FileRequester), because a page's media plays only for the client and device that rendered it. Nothing is computed again.
   • Shared state stays where it is: the page-media registry stays in file-view.ts. Sign-out and device revocation still call forgetPageMedia from index.ts.
   • Moved: FileKind, FileInfo and ProjectFavicon, verbatim with their doc comments, into the new shared/files.ts (types only).
   • Stays in index.ts: one call at the same place in the dispatch order, after the agent catalog and before the workspace routes. Every gate before it is untouched, including the watching-device refusal of file reads. The imports only these routes used leave index.ts: paneContext, resolveAgent, claudePaneSession, claudeSessionTempDir, findProjectFavicon, paneGet, isSecureRequest, the file-view helpers except forgetPageMedia, and ProjectFavicon.
   • Stays in protocol.ts: a type re-export of the three names, so every importer compiles unchanged.

Checks

• After the move: HERDR_TEST_MODE=unit bun test server/file-routes.test.ts server/file-view.test.ts server/project-favicon.test.ts server/files.test.ts server/open-access.test.ts server/startup-order.test.ts gives 71 pass, 0 fail. The pinning test is unchanged between the two commits.

• --color-moved on the move commit: git diff --color-moved=plain --color-moved-ws=allow-indentation-change HEAD~1 HEAD -- server shared shows 168 lines as moved: both branches (one indent level shallower in their new file), claudeTempFolder and the three types. The 26 other lines are:

  • in index.ts:
    • the shortened protocol, auth.ts and file-view.ts imports (each before and after);
    • the new file-routes.ts import;
    • the dropped paneGet import line;
    • the 2-line call.
  • in the new route file:
    • its 4-line header;
    • the 6 imports that did not move with the code;
    • the FileRequester type with its comment;
    • the function's doc comment and signature;
    • return null.
  • in protocol.ts: the re-export line.

  The imports only the moved code used (paneContext/resolveAgent, claudePaneSession, claudeSessionTempDir, findProjectFavicon) show as moved from index.ts into the route file.

• Client imports: bun run typecheck passes on both tsconfigs. No file in src/ or site/ imports shared/files.ts. shared/files.ts has no import and no value export.

• Sizes: server/index.ts goes from 704 to 657 lines and shared/protocol.ts from 1,381 to 1,353. The new modules are 69 and 29 lines.

• Risks checked:

  • Import cycles: none new. The route imports access.ts (type only), auth.ts, claude-store.ts, conversation.ts, file-view.ts, herdr/client.ts, http.ts, pane-context.ts and project-favicon.ts. These were all already imported by index.ts, and none of them imports index.ts.
  • Initialization order: unchanged. No module state moves.

• bun run check fast: passes (unit 6161 pass, 0 fail, 12 skip in 440 files, 8 at a time, 57.4s).

• CI's integration lane runs page-media.contract.test.ts, route-envelope.contract.test.ts and device-access.contract.test.ts against an isolated live herdr.

Overlapping open PRs

Open PRs that touch these files: #1652, #1598, #1442 and #1427. I checked each diff for the moved lines, the page-media names and the three file types:

• feat(chat): read native Copilot CLI transcripts #1652, feat(chat): read a droid pane's own session as its conversation #1442 and feat(tabs): move a one-pane tab to another workspace #1427 change none of them.
• fix(history): preserve Claude store identity through resume #1598 changes the bridgePath list in index.ts, which names /api/fs/. That list stays in index.ts, and this PR does not touch it.

No changelog fragment: users see no change.

📝 Summary

Summary by CodeRabbit

• File Access
  • File requests support file details and content, project icons, and rendered-page media. Unsupported methods, unavailable files, and invalid media requests receive appropriate error responses.
  • File lookup can use a pane’s working directory, and ambiguous paths return candidate matches.

The change moves file, favicon, and page-media request handling into a dedicated server module. It adds shared file types, delegates matching requests to the new handler, and adds route tests.

Changes: File route handling

Layer / File(s)	Summary
File route contracts and dispatch shared/files.ts, shared/protocol.ts, server/file-routes.ts	Adds shared file metadata and favicon types, re-exports them from the protocol module, and implements dispatch for file, favicon, and page-media requests.
Server integration and route tests server/index.ts, server/file-routes.test.ts	Delegates matching requests to the new handler with requester context. Tests cover request checks, absolute and pane-relative paths, file responses, favicon lookup, and page-media errors.

- Line 27: In the server test setup around createServer, set HERDR_SOCKET to a
disposable socket under the test state directory before creating the server, so
status polling cannot use the user's default socket. Save the previous
environment value and restore it in the test teardown, deleting HERDR_SOCKET if
it was originally unset.
