Summary

Follow-up to #30253. Main CI Type Check + Test were still red after #30253
landed because:

  1. oauth-cli.test.ts still imported requirePlatformClient from
    cli/commands/oauth/shared.ts, but feat(cli): migrate remaining oauth commands to thin IPC wrappers #30251 moved that function
    server-side into runtime/routes/oauth-commands-routes.ts. (My
    rebase commit included this cleanup; it was lost in the squash merge
    timing.)
  2. mcp-auth-routes.test.ts mocked config/loader.js with only
    loadRawConfig, which polluted the global module namespace under
    bun test. Downstream files importing saveRawConfig from the same
    module then failed at load with SyntaxError: Export named 'saveRawConfig' not found.
  3. credential-security-invariants.test.ts allowlist still referenced
    files removed by the IPC migrations (cli/commands/credentials.ts,
    cli/commands/platform/{connect,disconnect,index}.ts,
    meet/session-manager.ts) and was missing the new IPC route modules
    (runtime/routes/{credential,platform}-routes.ts).
  4. oauth-providers-routes.test.ts asserted snake_case fields on the
    GET-by-key endpoint, but that endpoint uses serializeProviderFull
    which emits camelCase. The list endpoint (snake_case via
    serializeProviderSummary) is intentionally a different wire format.
  5. oauth/__tests__/connect.test.ts mock of ipc/cli-client.js only
    exported cliIpcCall. mock.module in bun is a global replacement,
    so subsequent test files importing exitFromIpcResult from the same
    module load against the mocked namespace and fail.

Changes

File Fix
__tests__/oauth-cli.test.ts Drop requirePlatformClient destructure + orphaned describe block (3 tests covering the removed function)
__tests__/mcp-auth-routes.test.ts Add saveRawConfig: () => {} to config/loader.js mock
__tests__/credential-security-invariants.test.ts Update allowlist for IPC-migrated routes
__tests__/oauth-providers-routes.test.ts Switch GET-by-key assertions to camelCase + add inline comment documenting the wire-format split
cli/commands/oauth/__tests__/connect.test.ts Add exitFromIpcResult passthrough to cli-client.js mock

Out of scope

The oauth token <provider-key> and oauth providers list/register/update/delete
tests in oauth-cli.test.ts still fail. These broke because #30251 routed
the oauth commands through IPC, but the test setup mocks
withValidToken/mockListProviders/etc. directly and never reaches the
IPC layer. Fixing these requires updating each test to mock the new IPC
flow — that's a separate, deeper PR. Filing under follow-up. None of
these failures predate #30251.

Test plan

  • bunx tsc --noEmit → 0 errors
  • bun run lint → 0 errors, 45 warnings (pre-existing)
  • bun test src/__tests__/mcp-auth-routes.test.ts → 9/9 pass
  • bun test src/__tests__/credential-security-invariants.test.ts → green
  • bun test src/__tests__/oauth-providers-routes.test.ts → green
  • Full Test job via CI

Follow-up to #30253. After that fix landed, Type Check + Test were still red.

1. oauth-cli.test.ts — drop requirePlatformClient destructure + orphan
   describe block. #30251 moved the function from cli/commands/oauth/shared.ts
   to a private helper inside runtime/routes/oauth-commands-routes.ts.

2. mcp-auth-routes.test.ts — add saveRawConfig: () => {} to config/loader.js
   mock. bun's mock.module is a global namespace replacement; partial mocks
   silently drop other exports and downstream files load against the
   replaced namespace, failing with SyntaxError: Export not found.

3. credential-security-invariants.test.ts — refresh allowlist for the IPC
   migration. The CLI command files cli/commands/credentials.ts and
   cli/commands/platform/{connect,disconnect,index}.ts no longer exist;
   add the new runtime/routes/{credential,platform}-routes.ts in their
   place. Remove obsolete meet/session-manager.ts entry.

4. oauth-providers-routes.test.ts — switch GET-by-key assertions from
   snake_case to camelCase. The GET-by-key endpoint uses serializeProviderFull
   (camelCase by design); the list endpoint uses serializeProviderSummary
   (snake_case). Add comment documenting the split.

5. oauth/__tests__/connect.test.ts — add exitFromIpcResult passthrough to
   cli-client.js mock so downstream test files that import it don't fail
   when bun's global mock.module replaces the namespace.

Out of scope: the deeper oauth token / oauth providers CRUD test failures
in oauth-cli.test.ts (and the new test files under oauth/__tests__/)
require updating test setups to mock the new IPC flow. Filing as a
follow-up.

🚩 Many connect.test.ts tests will fail due to unhandled IPC methods in mockCliIpcCallFn

The connect command (connect.ts) was rewritten to use IPC calls (cliIpcCall) for provider validation (oauth_providers_by_providerKey_get) and mode detection (oauth_mode_get) before reaching the managed/BYO flow. However, most tests outside the "IPC-first path" describe block (e.g., "managed mode with --no-browser", "BYO missing app", "manual-token provider") don't set up mockCliIpcCallFn to handle these new IPC methods — they still set mockGetProvider and mockIsManagedMode which are no longer consumed by the new connect.ts. These tests will fail at the first IPC call since the default mock returns { ok: false }. This is likely a known state given the PR title says "reduce Test failures" (not eliminate), but the test file needs a broader update to align with the IPC-based connect command.

🔴 exitFromIpcResult mock calls process.exit() directly, terminating the test runner

The newly added exitFromIpcResult mock in connect.test.ts calls process.exit() directly (lines 167-170), which will terminate the entire Bun test runner process whenever any test triggers that code path. For example, the "unknown provider returns error with hint" test (line 322) hits exitFromIpcResult because mockCliIpcCallFn defaults to { ok: false } with no statusCode, causing connect.ts:141 to call exitFromIpcResult(providerCheck)process.exit(10).

The equivalent mock in assistant/src/__tests__/oauth-cli.test.ts:352-364 correctly uses process.exitCode = N followed by throw new Error(...), which the runCommand/runCli try-catch wrapper handles gracefully without killing the process.

Suggested change
exitFromIpcResult: (r: {
ok: boolean;
error?: string;
statusCode?: number;
}) => {
process.stderr.write((r.error ?? "Unknown error") + "\n");
if (r.statusCode === undefined) process.exit(10);
if (r.statusCode >= 500) process.exit(3);
if (r.statusCode >= 400) process.exit(2);

} else if (r.statusCode >= 400) {
process.exitCode = 2;
} else {
process.exitCode = 1;

🚩 oauth-cli.test.ts exitFromIpcResult mock may cause exit-code mismatches with pre-existing tests

The newly added exitFromIpcResult mock at assistant/src/__tests__/oauth-cli.test.ts:352-364 sets process.exitCode = 10 for IPC transport errors (no statusCode). Before this mock existed, calling exitFromIpcResult would throw a TypeError ("not a function"), which the runCli catch block would handle by setting process.exitCode = 1. Pre-existing tests like "daemon connect-refused → exit 1" at line 1300 expect exitCode to be 1, but will now get 10 due to the mock properly simulating the exit-code matrix. These tests need their expectations updated to match the real exitFromIpcResult behavior (exit code 10 = IPC transport error, not 1).

…0251

The CLI→IPC migration in #30251 added 9 new oauth endpoints to
http-server.ts dispatch but didn't add corresponding policy entries,
breaking the route policy coverage guard test.

Added policies for:
- oauth/disconnect (settings.write, local)
- oauth/mode (settings.read, local)
- oauth/mode.set (settings.write, local)
- oauth/status (settings.read, local)
- oauth/ping (settings.read, local)
- oauth/token (settings.read, local)
- oauth/request (settings.write, local)
- oauth/managed-connect.start (settings.write, local)
- oauth/managed-connect/poll (settings.read, local)

These follow the CLI-IPC-local convention set by #30250: scopes
matching read/write semantics, allowedPrincipalTypes locked to ["local"].
The existing oauth/* entries in ACTOR_ENDPOINTS continue to cover the
actor-token surface for the legacy paths.
After the CLI IPC migration (#30238-#30251), these 8 OAuth CLI test
files still mock pre-IPC code paths (oauth-store.js, withValidToken,
etc.) that the CLI no longer calls directly. The CLI now goes through
cliIpcCall(...) and the daemon route handlers in
runtime/routes/oauth-commands-routes.ts execute the actual work.

Skip the obsolete describe blocks until rewritten to mock
'../../../../ipc/cli-client.js' with canned IPC responses (matching
the pattern in connect.test.ts via mockCliIpcCallFn). The daemon-side
logic is still exercised by route-handler tests
(oauth-providers-routes.test.ts and oauth-connect-routes.test.ts).

Also fix connect.test.ts exitFromIpcResult mock: switch from
process.exit() (which kills bun's test runner) to process.exitCode +
throw, so runCommand's try/catch can capture and preserve the exit
code. Flagged by Devin Review on #30257.

Files skipped: disconnect, mode, ping, providers-delete,
providers-register, providers-update, status, token.

Follow-up: rewrite these test files to mock the IPC client and
exercise CLI argument parsing / output formatting without re-testing
daemon-side logic.
Continuing the unblock work from 560c024. The following CLI test
files still target pre-IPC code paths (oauth-store.js, withValidToken,
direct DB access, etc.) that the CLI commands no longer call directly
after the IPC migration (#30238-#30251). Without IPC-layer mocking
they crash the bun test runner (exit 10) or fail with stale
assertions.

Skipping with TODO until properly rewritten to mock '../ipc/cli-client.js'
with canned IPC responses. Daemon-side logic remains covered by
route-handler tests.

Files / scope:
- oauth-cli.test.ts: skip the 10 pre-IPC describe blocks (token,
  providers list, apps upsert, ping, connect managed/BYO errors,
  mode, scope-separator, refresh-url, revoke-url). Leave
  requirePlatformConnection as-is (still passes).
- credentials-cli.test.ts: skip whole suite (all paths now go through
  IPC).
- usage-cli.test.ts: skip one IPC-dependent breakdown test.
- inference-send.test.ts: skip the 8 IPC-dependent describes
  (success paths, --system-prompt, --json, --model, --max-tokens,
  --profile). Help text and arg validation describes remain.
- routes.test.ts: skip both 'assistant routes list' and
  'assistant routes inspect' (commands now IPC-routed).

Follow-up: rewrite these files using the IPC-mock pattern from
connect.test.ts (mockCliIpcCallFn) and shift assertions to focus on
CLI plumbing (arg parsing, output formatting) rather than re-testing
daemon behaviour.
The 'breakdown table prints friendly profile fallback labels' test
exits with code 10 in CI: usage breakdown CLI now goes through
cliIpcCall to the daemon, hits the real exitFromIpcResult when no
daemon is running, and process.exit(10) terminates the test runner.
Passes locally only when a daemon happens to be running.

Skipping with the same TODO pattern as the rest of the IPC-dependent
CLI tests in this file.

Latest HEAD 6ee140c: addressed Devin finding #1 (exitFromIpcResult: process.exit → exitCode+throw) and #2 (skipped pre-IPC describe blocks across oauth/credentials/usage/inference-send/routes test files with TODOs referencing the connect.test.ts mockCliIpcCallFn pattern). All CI green.

P1 Badge Stop terminating the test runner in mocked IPC error path

This mock calls process.exit(...) directly, which can terminate Bun’s entire test process whenever any test invokes exitFromIpcResult from the globally mocked ../../../../ipc/cli-client.js. Because mock.module is process-global and this file’s top-level mock runs even though the suite is describe.skip, downstream tests can still hit this branch and abort the run instead of surfacing an assertion failure. Mirror the safer pattern used elsewhere (process.exitCode + throw) so failures are catchable inside test helpers.

Follow-up to #30257, which merged with describe.skip on most of the
oauth/usage/inference CLI tests to unblock CI after the CLI→IPC
migration cascade (#30238#30251). This PR closes out the debt:

ADD daemon-side coverage for the IPC endpoints introduced in #30251:
  - assistant/src/__tests__/oauth-commands-routes.test.ts (+711 lines,
    36 tests across all 9 endpoints: oauth_disconnect, oauth_mode_get,
    oauth_mode_set, oauth_status, oauth_ping, oauth_token,
    oauth_request, oauth_managed_connect_start,
    oauth_managed_connect_poll). These handlers had no route-level
    unit tests since the migration — that gap predates #30257 but
    needed to close before the CLI dupes could be deleted.

DELETE outright (every top-level describe was describe.skip'd against
pre-IPC in-process logic that no longer exists):
  - 9 × assistant/src/cli/commands/oauth/__tests__/*.test.ts
    (connect, disconnect, mode, ping, status, token,
     providers-{register,update,delete})
  - assistant/src/__tests__/credentials-cli.test.ts (1232 lines)
  - assistant/src/cli/commands/__tests__/routes.test.ts (576 lines)

TRIM down to passing CLI-plumbing tests only:
  - oauth-cli.test.ts: 2103 → 135 lines (kept requirePlatformConnection)
  - usage-cli.test.ts: 153 → 85 lines (kept invalid-arg validation)
  - inference-send.test.ts: 643 → 236 lines (kept help text +
    no-message guard + --max-tokens validation)

Net: 15 files changed, +797 / -9910.

Coverage check: the underlying business logic that the deleted tests
nominally covered already runs through oauth-store.test.ts,
credential-vault.test.ts, oauth-apps-routes.test.ts,
oauth-providers-routes.test.ts, oauth-connect-routes.test.ts, and
usage-routes.test.ts. The new oauth-commands-routes.test.ts file
closes the only real coverage gap.

Follow-ups (not blocking, called out in file-level docstrings):
  - CLI plumbing tests for exitFromIpcResult exit-code mapping,
    shouldOutputJson/writeOutput formatting, and the oauth token
    shell-lockdown guard
  - IPC-mock-based tests for the trimmed inference-send / usage
    paths if anyone wants stronger end-to-end coverage
