Summary

  • repin the Messaging contract to monorepo dev 6918c56135e28ba64557e344cb72889f1f517eb5 and exact SHA-256 2f5d06b1e5103a00e62896636f122c570729578afd3cc5636ae57711941d85cf
  • remove the retired session.qr webhook event and SessionQrPayload public type
  • add MessagingClient.quickLinks create, retrieve, and cancel for the authenticated hosted lifecycle
  • accept the single pmfa_pt_ project-token format as a server-only Messaging credential and reject browser client tokens before QuickLink transport
  • document QuickLink as the standard pairing flow while retaining entitlement-gated direct pairing routes
  • move coverage to 274 covered and 128 explicitly excluded operations, with zero missing, partial, or changed entries

Verification

  • formatting, lint, strict typecheck, root and workspace builds, coverage, and name checks pass
  • 66 test files and 398 tests pass, including clean packed-tarball consumers
  • package dry-run and production audit pass with zero runtime dependencies and zero vulnerabilities

A feature video is not applicable: this is a server SDK contract and transport change with no visual workflow.

Summary by CodeRabbit

  • New Features
    • Added hosted QuickLink creation, retrieval, and cancellation through the Messaging client.
    • Added support for project-token credentials with project binding.
  • Changes
    • QuickLink is now the standard device-pairing flow.
    • Direct QR and phone pairing require an explicit entitlement.
    • Browser client tokens cannot access hosted QuickLink operations.
    • Removed support for the session.qr webhook event.
  • Documentation
    • Updated pairing guidance and credential information.
  • Tests
    • Expanded coverage for QuickLink operations and credential validation.

📝 Walkthrough

Walkthrough

The OpenAPI contract removes session QR webhook models and operations. The SDK adds hosted QuickLink lifecycle methods, project-token support, updated credential rules, related exports, documentation, coverage metadata, and tests.

Changes

Messaging QuickLink update

Layer / File(s) Summary
QuickLink contract and resource
packages/typescript/src/messaging/quicklinks.ts, packages/typescript/src/messaging/client.ts, packages/typescript/src/index.ts, contracts/coverage.json, packages/typescript/test/quicklinks.test.ts
The SDK adds typed QuickLink creation, retrieval, and cancellation through MessagingClient.quickLinks. Tests cover responses, URL encoding, request payloads, idempotency headers, authentication, and operation coverage.
Credential and runtime rules
packages/typescript/src/credentials.ts, packages/typescript/src/messaging/client.ts, packages/typescript/test/credentials.test.ts, packages/typescript/test/quicklinks.test.ts
Messaging credentials now support validated project tokens. Browser runtimes reject server credentials, and QuickLink methods reject client tokens before transport requests.
Direct pairing contract retirement
contracts/openapi.messaging.json, packages/typescript/src/webhooks/*, packages/typescript/src/messaging/sessions.ts, packages/typescript/src/index.ts, packages/typescript/test/webhooks.test.ts
The contract and SDK remove session QR webhook schemas, events, mappings, and exports. Direct pairing methods document entitlement requirements and QuickLink usage.
Documentation and revision alignment
README.md, packages/typescript/README.md, contracts/source.json, contracts/README.md, contracts/coverage.json, packages/typescript/test/coverage*.test.ts
Documentation describes credential types, QuickLink lifecycle methods, pairing behavior, and project binding. Contract revisions, snapshot digests, and coverage expectations use the new source revision.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 21bc6

QuickLink lifecycle support, project-token handling, and the retirement of the session QR webhook are implemented with browser-worker credential protection in place. No current merge-blocking risk remains.

P2 Badge Update reconciliation notes for the new contract pin

Repinning this file makes the existing Reconciliation section describe the wrong refresh. Comparing the parent 8c244aab... snapshot with 6918c561... shows no structural operation-fingerprint changes; the actual changes are the direct-pairing descriptions and removal of the session.qr webhook schemas/callback. The current text instead attributes browser-candidate, agent-token, participant, and TURN changes from an earlier refresh, so the contract provenance documentation is now misleading and should be updated with the pin.

P2 Badge Update the coverage totals for the new QuickLink mappings

The ledger changes all three authenticated QuickLink operations from excluded to covered, and the repository coverage checker now reports 274 covered and 128 excluded operations. Leaving this table at 271/131 makes the contract coverage summary contradict both contracts/coverage.json and the updated regression assertion in coverage.test.ts.

Reject project tokens in browser workers.

assertServerRuntime() checks only window. Browser Worker and ServiceWorker globals do not provide window, so a project token can reach quickLinks and expose a reusable server credential. Reject these runtimes before creating HttpTransport, and add a regression test that confirms quickLinks.retrieve() throws before fetch.
