When those judge-driven fixes change repository files, re-run the `capture-visual-proof` step once for the updated shipped change, replace prior proof evidence, then run one more focused judge pass against the refreshed diff, validation state, and refreshed proof result before delivery. Otherwise re-review the updated diff and rerun the judge once if needed without a second proof step. Fix actionable self-review issues too, re-review changes, and explicitly document unresolved gaps. diff --git a/packages/sdk/src/server/lib/task-runs/__tests__/dequeue-helpers.test.ts b/packages/sdk/src/server/lib/task-runs/__tests__/dequeue-helpers.test.ts index 5ab0268410..f2ca0117ed 100644 --- a/packages/sdk/src/server/lib/task-runs/__tests__/dequeue-helpers.test.ts +++ b/packages/sdk/src/server/lib/task-runs/__tests__/dequeue-helpers.test.ts @@ -16,6 +16,7 @@ const { mockNotifyWebTaskInitiatorOnSettle, mockEnqueueWebTaskInitiatorSettleNotification, mockCaptureTaskSettled, + mockIsTypeSafeJudgmentConfigured, } = vi.hoisted(() => ({ mockDecryptSecrets: vi.fn(), mockEnvironmentVariablesFindMany: vi.fn(), @@ -31,6 +32,7 @@ const { mockNotifyWebTaskInitiatorOnSettle: vi.fn(), mockEnqueueWebTaskInitiatorSettleNotification: vi.fn(), mockCaptureTaskSettled: vi.fn(), + mockIsTypeSafeJudgmentConfigured: vi.fn(async () => false), })); vi.mock('@roomote/db/encryption', () => ({ @@ -109,6 +111,10 @@ vi.mock('@roomote/cloud-agents/server', () => ({ releaseTaskRun: vi.fn(), })); +vi.mock('@roomote/cloud-agents/server/typesafe-judgment', () => ({ + isTypeSafeJudgmentConfigured: mockIsTypeSafeJudgmentConfigured, +})); + vi.mock('@roomote/telemetry/server', () => ({ captureTaskSettled: (...args: unknown[]) => mockCaptureTaskSettled(...args), })); @@ -1105,6 +1111,20 @@ describe('redactControlPlaneEnvVars', () => { }); describe('fetchResolvedRuntimeEnvVars', () => { + it('turns on the turn-end completion check only with a hosted judgment model', async () => { + mockResolveSandboxModelRuntimeEnv.mockResolvedValue({}); + + // An operator-set value never stands in for the platform's own answer. + await expect( + fetchResolvedRuntimeEnvVars({ ROOMOTE_COMPLETION_GATE: 'true' }), + ).resolves.not.toHaveProperty('ROOMOTE_COMPLETION_GATE'); + + mockIsTypeSafeJudgmentConfigured.mockResolvedValueOnce(true); + await expect(fetchResolvedRuntimeEnvVars({})).resolves.toMatchObject({ + ROOMOTE_COMPLETION_GATE: 'true', + }); + }); + it('withholds the sandbox OpenRouter key from ordinary tasks', async () => { mockResolveSandboxModelRuntimeEnv.mockResolvedValueOnce({}); diff --git a/packages/sdk/src/server/lib/task-runs/dequeue-helpers.ts b/packages/sdk/src/server/lib/task-runs/dequeue-helpers.ts index a22fdb09e0..2b630714b3 100644 --- a/packages/sdk/src/server/lib/task-runs/dequeue-helpers.ts +++ b/packages/sdk/src/server/lib/task-runs/dequeue-helpers.ts @@ -6,6 +6,7 @@ import { INFERENCE_GATEWAY_KEYS_ENV_VAR_NAME, OPENCODE_AUTH_CONTENT_ENV_VAR_NAME, SANDBOX_OPENROUTER_API_KEY_ENV_VAR_NAME, + TASK_COMPLETION_GATE_ENV_VAR, TASK_MODEL_CONTEXT_WINDOWS_ENV_VAR_NAME, parseInferenceGatewayKeys, parseModelProviderEnvKeys, @@ -50,6 +51,7 @@ import { resolvePublicGitAuthor, resolveRunCommitAuthor, } from '@roomote/cloud-agents/server'; +import { isTypeSafeJudgmentConfigured } from '@roomote/cloud-agents/server/typesafe-judgment'; import { withBootstrapFailureSignal } from '../../../bootstrap-failure-signal'; import { notifySourceRunOnSettle } from './notify-source-run-on-settle'; @@ -292,6 +294,15 @@ export async function fetchResolvedRuntimeEnvVars( ), ); + // The turn-end completion check only runs where a hosted judgment model can + // answer it; everywhere else the sandbox keeps the judge pass.
