Summary

  • complete the DPoP-bound End-User Connection authorization, inspection, pagination, scope-upgrade, revocation, and recent-use surface
  • preserve workspace, Application, External Subject, and provider-account isolation while reconciling revocation with pending Action Intents and Approval Requests
  • expose bounded terminal projections and stable reauthorization/scope errors through the protocol, SDK, OpenAPI, and operation registry
  • retain bounded authorization completion across End-User Session cleanup and persist provider-reported granted scopes

Verification

  • pnpm lint
  • pnpm typecheck
  • pnpm format:check
  • pnpm build
  • pnpm check:contracts
  • pnpm --filter @linea/sdk test:pack
  • Platform API: 35 suites / 152 tests passed
  • Execution worker: 23 suites / 239 tests passed
  • Protocol: 16 tests passed
  • SDK: 63 tests passed
  • Connection HTTP acceptance: 14 tests passed
  • Connector read and side-effect acceptance: 44 tests passed
  • Approval/Connection reconciliation acceptance: 8 tests passed without ambient credential-key environment

Closes #162

Summary by CodeRabbit

  • New Features
    • Connections can now be listed with pagination, and their recent uses can be reviewed in a paginated history with sensitive details redacted.
    • Authorization results can be retrieved by ID. Existing connections can also be reauthorized or upgraded with additional scopes.
    • Read and action operations now report clear errors when a connection needs reauthorization or lacks required scopes.
  • Bug Fixes
    • Authorization requests remain available for 24 hours, and completed actions are not dispatched again if a connection later requires reauthorization.

RetriggerConfidence Score: 5/5

The PR appears safe to merge; no new actionable correctness, security, or repository-rule violations remain.

Summary

This PR completes the end-user Connection management surface across persistence, API, protocol, SDK, and connector execution.

  • Adds authorization-result inspection, scope upgrades and reauthorization, cursor-paginated Connection/use history, and stable Connection authority errors.
  • Persists provider-granted scopes and bounded authorization outcomes independently of short-lived end-user sessions.
  • Reconciles revocation and authority changes with pending Action Intents while preserving durable terminal outcomes.
  • Extends public contracts, generated documentation, SDK methods, migration state, and acceptance coverage.

The PR does not yet appear safe to merge because the migration graph remains forked and GitHub scope upgrades can still begin an OAuth flow that is guaranteed to fail at callback.

Findings

  1. P1 Migration history forks ▶
  2. P2 GitHub upgrades fail late ▶
Summary

Completes the end-user Connection lifecycle and related public interfaces:

  • Adds authorization-result inspection, explicit scope upgrades and reauthorization, compatible Connection pagination, and redacted use history.
  • Retains terminal authorization results beyond end-user session cleanup and records provider-granted scopes.
  • Reconciles revocation with pending approvals and Action Intents while preserving durable terminal replay outcomes.
  • Publishes the new operations and stable authority errors through the protocol registry, SDK, OpenAPI, and generated route reference.

📝 Walkthrough

Walkthrough

The change adds connection authorization lookup, scope upgrades and reauthorization, and paginated connection and use listings. It records connector read outcomes and exposes these operations through the platform API and user SDK.

Changes

Connection Management and History

Layer / File(s) Summary
Connection contracts and persisted records
packages/protocol/src/resources/connection.ts, packages/protocol/src/shared/pagination.ts, packages/protocol/src/errors/error-code.ts, packages/db/src/schema/connection.ts, packages/db/drizzle/20260923195802_shocking_sumo/*
Protocol schemas define authorization, scope-upgrade, pagination, and use-history data. Database changes add authorization outcomes and connection read-use records.
Authorization lifecycle and connector enforcement
packages/db/src/repositories/connection.repository.ts, packages/db/src/repositories/action-intent.repository.ts, apps/platform-api/src/connections/*, packages/connectors/src/connector-gateway.ts, apps/execution-worker/src/connectors/connector-side-effect.spec.ts
Authorization requests can target existing connections and record completion outcomes. Authority checks distinguish reauthorization-required and insufficient-scope results. Revocation supports connections without encrypted credentials.
Connection listing and use history
packages/connectors/src/connector-gateway.ts, packages/db/src/repositories/*, apps/platform-api/src/connections/connections.service.ts, apps/platform-api/src/public-runtime/*, apps/execution-worker/src/connectors/connector-read.spec.ts
Connector reads record succeeded or failed outcomes. The service combines read uses and terminal Action Intents, then returns cursor-paginated connection and use history.
Public API and SDK operations
apps/platform-api/src/connections/connections.controller.ts, packages/protocol/src/operations/connections.ts, packages/protocol/src/registry.ts, packages/protocol/src/operation-metadata.ts, packages/sdk/src/user/*, docs/openapi.json, docs/route-reference.md
The API and SDK expose authorization lookup, scope upgrades, and paginated connection and use listings. Tests cover pagination, response fields, and session isolation.

Merge Risk: 🟡 Moderate · up to a7fec

If storing an OAuth callback fails and then recording that failure also fails, the provider grant is left live without being stored or revoked. The user sees a server error instead of the failed-authorization redirect. Recent-use history pagination can also occasionally skip an entry when two actions finish within the same millisecond. Reorder the cleanup before merging; the pagination fix is a small follow-up.

Addressed the outside-diff Concurrent upgrades drop scopes finding in 3347628. Authorization completion locks the target Connection and rejects a callback unless its granted scope set remains a superset of every scope currently on that Connection, preventing a later callback from removing authority granted by an earlier one. The concurrent callback suite remains green.

218-248: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Move the GitHub scope-policy check into one shared helper.

startScopeUpgrade copies the GitHub validation from startAuthorization (lines 120-150): the policy lookup, githubAuthorizationScopes, the maxScopes check, and the exact-order comparison. This is authorization policy logic. If a later fix changes one copy only, the two entry points enforce different policies. Extract one private method and call it from both methods.

Proposed refactor
private async assertGithubScopes(
  principal: EndUserPrincipal,
  scopes: string[],
): Promise<void> {
  const application = await repositories.application.getApplicationById(
    db,
    principal.workspaceId,
    principal.applicationId,
  )
  const providerPolicy = application?.connectorAccessPolicy.providers.find(
    (candidate) => candidate.provider === 'github',
  )
  let requiredScopes: string[]
  try {
    requiredScopes = githubAuthorizationScopes(providerPolicy?.actionFamilies ?? [])
  } catch {
    throw new ForbiddenException(
      publicError('scope_denied', 'Connection authorization denied'),
    )
  }
  if (
    requiredScopes.some((scope) => !providerPolicy?.maxScopes.includes(scope)) ||
    requiredScopes.length !== scopes.length ||
    requiredScopes.some((scope, index) => scope !== scopes[index])
  ) {
