Upgrade all libp2p ecosystem packages to versions from the libp2p-v3.1.7
monorepo tag to ensure cross-package compatibility.
Key changes:
- libp2p 2.10.0 → 3.1.7, @libp2p/interface 2.11.0 → 3.1.1
- @libp2p/webrtc 5.2.24 → 6.0.15, @libp2p/websockets 9.2.19 → 10.1.7
- @chainsafe/libp2p-noise 16.1.5 → 17.0.0, yamux 7.0.4 → 8.0.1
- @chainsafe/libp2p-quic 1.1.8 → 2.0.1
- @multiformats/multiaddr 12.x → 13.x, multiaddr-matcher 2.x → 3.x
- Replace it-byte-stream with @libp2p/utils for byteStream()
- Fix protocol handler signature: ({ stream, connection }) → (stream, connection)
- Migrate multiaddr API: getPeerId/toOptions/protoNames → getComponents() + CODE_* constants
- Remove websocket filter option (now default behavior in v10)
- Remove stale @chainsafe/libp2p-yamux SES patch (returnlessSource removed in v8)
- Update node-datachannel references (renamed from @ipshipyard/node-datachannel)
- Add relay connectivity e2e smoke test

The browser-to-browser libp2p PoC has been superseded by the production implementation in ocap-kernel/src/remotes/ and kernel-utils. Removing to reduce maintenance burden. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…patch remnants - Use findLast() instead of find() for CODE_P2P to match getPeerId() semantics (last /p2p/ component, not first) — critical for circuit relay multiaddrs with two /p2p/ segments - Fix webrtc protocol code in test mock: 281 (not 280 which is webrtc-direct) - Remove patch-package references from kernel-utils (yamux patch was deleted) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

findLast requires ES2023 lib target which CI doesn't have. Extract a getLastPeerId() helper that iterates components to find the last /p2p/ peer ID, preserving the correct semantics for circuit relay multiaddrs. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

The relay-connectivity test now checks if port 9001 is already in use before starting its own relay. In CI (or when remote-comms tests run first), the existing relay is reused. Locally, it starts its own. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
node-datachannel v0.29.0 (via @libp2p/webrtc v6) throws an async uncaught exception when a DataChannel close races with a pending send. This is benign (the connection is already tearing down) but Vitest v4 treats uncaught exceptions as test failures. Add a setup file that catches only this specific error pattern while re-throwing everything else. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- Add harden(ConnectionFactory) after class definition per CLAUDE.md - Fix stopWithTimeout to reject on timeout (matching remote-comms.test.ts) - Add failure-path test: kernel with unreachable relay still starts - Use proper cleanup with labeled stopWithTimeout in all test teardown Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…tion The same getComponents().find() pattern for extracting ip4/ip6/dns host was repeated in two places. Extract a getHost() helper alongside the existing getLastPeerId() and isPlainWs() helpers. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Move pure utility functions out of ConnectionFactory into dedicated utils modules with co-located tests: - utils/multiaddr.ts: getLastPeerId, getHost, isPlainWs - utils/network.ts: isPrivateAddress Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Move RELAY_RECONNECT_*, HANDSHAKE_TIMEOUT_MS, and DEFAULT_CONSECUTIVE_ERROR_THRESHOLD from connection-factory.ts, handshake.ts, and reconnection.ts into the existing constants.ts file. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

## Summary Adds an explicit **DO NOT SKIP** directive to Phase 2 (Automated PR review) of the `/pr` skill, preventing the review subagent phase from being bypassed. - Adds mandatory enforcement language at the top of Phase 2 - The only exception remains docs-only changes (already documented) During the libp2p v3 upgrade (#900), the review phase was skipped because the changes appeared "mechanical". The review — when eventually run — caught a `find()` vs `findLast()` bug in the multiaddr migration that would have broken circuit relay address routing. This change ensures that doesn't happen again. 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Low Risk** > Low risk documentation-only change that tightens process guidance without affecting runtime code.

Summary
Upgrade all libp2p ecosystem packages from v2 to v3, pinned to the exact versions from the
libp2p-v3.1.7monorepo tag to ensure cross-package compatibility. Also removes the superseded@ocap/brow-2-browPoC package.Changes

All unit tests pass across the full monorepo (46 turbo tasks). All 62 e2e tests pass including the full remote-comms suite (bidirectional messaging, reconnection, queueing, incarnation detection, DGC) and the new relay connectivity smoke tests. Full build succeeds across all 23 remaining packages.

Note
Medium Risk
Upgrades core networking dependencies (
libp2p/@libp2p/*/@multiformats/*) across the monorepo and adapts connection/multiaddr handling to new APIs; regressions would impact relay connectivity and remote comms. Changes are well-covered by updated and expanded E2E tests, but the dependency jump is large and includes native WebRTC (node-datachannel) behavior.Overview
Upgrades the libp2p ecosystem to v3 (including
libp2p,@libp2p/interface,@libp2p/webrtc, QUIC/TCP/WebSockets/WebTransport, and@multiformats/multiaddrv13) and updates workspaceresolutionsaccordingly.Adapts remote-comms to breaking API changes: switches
byteStreamusage to@libp2p/utils, updates inbound protocol handler signatures, removes the WebSocket filter option, and replaces deprecated multiaddr helpers (getPeerId/toOptions/protoNames) with new shared utilities (getLastPeerId,getHost,isPlainWs) plus extractedisPrivateAddresslogic.E2E tests are adjusted and expanded: adds a relay connectivity smoke test, deduplicates helper logic (
stopWithTimeout,getRemoteCommsPeerId), and introduces a Vitest setup to suppress known benignnode-datachanneluncaught exceptions. Cleans up legacy artifacts by removing the@ocap/brow-2-browPoC package, dropping the@chainsafe/libp2p-yamuxpatch/patch-packagewiring, and updating native rebuild scripts for thenode-datachannelrename.Written by Cursor Bugbot for commit 277d212.
