feat: Add quic with tcp

[abergasov]

Summary by CodeRabbit

• New Features

  • Gateway mesh connections now support QUIC over UDP alongside TCP.
  • Nodes advertise and listen on both TCP and UDP addresses for IPv4 and IPv6 connectivity.
  • Docker deployments expose the mesh port over both protocols.

• Documentation

  • Updated setup, security, and gateway guidance to describe QUIC-v1 and the requirement for TCP and UDP reachability.

• Tests

  • Added coverage validating inbound TCP and QUIC connections.

• Chores

  • Docker image publishing now also runs for development updates.

📝 Walkthrough

Walkthrough

The mump2p gateway now supports inbound TCP and QUIC-v1 connections over UDP. Advertised peer addresses include both transport types. Docker images and Compose services publish UDP port 33213 alongside TCP. Documentation now states that mesh connectivity requires both protocols. Integration tests cover inbound TCP and QUIC connections.

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

Merge Risk: 🟡 Moderate · up to 3d57c

This PR adds branch-triggered container publishing, but overlapping runs can race while updating shared image tags and deployment state, producing failed publishes or stale images. The workflow also lacks bounded execution and least-privilege token settings, while the troubleshooting material names a different default port than runtime. Merge should wait for these safeguards or explicit owner acceptance.

Full details: Docstring Coverage

Explanation

Docstring coverage is 20.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 5 functions across 4 files. (1 skipped: 1 unsupported.)

Full details: Scope Discipline

Explanation

The QUIC changes are generally within scope: transport code, advertised addresses, tests, Docker exposure, and related documentation. However, the PR also changes .github/workflows/docker-publish.yml to publish on every push to development and main. This does not implement QUIC support or document a required rollout. The change is isolated in commit 3d57c3f with subject measure rlnc funcs, and the diff provides no explanation for this broader publishing-policy change.

Full details: Behavior Safety

Explanation

PASS. NewNode retains TCP listeners and adds QUIC-v1 UDP listeners on the configured port. BuildQUICTCPAddr combines the existing TCP and pinned QUIC address builders. Bootstrap registration uses this combined address set. The focused transport test verifies inbound TCP and QUIC connections, transport type, and direction. Docker and Compose mappings expose both protocols. No changed invariant or untested non-trivial behavior was found.

Full details: Over-Engineering

Explanation

No explicit over-engineering condition is introduced. The new address helper combines TCP and QUIC advertised addresses and is reused by both node creation and bootstrap registration. The existing cached address closure is unchanged. No existing function signatures changed. The transport test exercises observable inbound TCP and QUIC connections and checks the negotiated transport, not an internal implementation detail. The external-IP seam makes that integration test deterministic.

Full details: Security

Explanation

The new development push trigger creates a secret-bearing workflow on an unprotected branch. The workflow checks out the pushed branch, then passes GH_APP_PRIVATE_KEY to a branch-controlled local composite action, passes a GitHub token to the branch-controlled Dockerfile as a BuildKit secret, logs into Docker Hub, and later creates infrastructure/gitops tokens. Repository metadata reports development as unprotected. A user who can push to that branch, or a compromised account, can change the workflow, local action, or Dockerfile to exfiltrate these credentials. This is a pull-request-introduced injection and secret-exposure path. The QUIC changes do not add a separate security failure: the pinned address helper validates ports and the existing authenticated handshake callbacks remain in use.

Resolution

Do not run the privileged publish workflow for development. Keep secret-bearing publishing limited to protected, review-gated refs, or split development publishing into a workflow with no repository secrets. If development publishing is required, protect the branch with required reviews and status checks, use an environment approval gate, checkout an immutable reviewed commit, and run only action code from a protected ref. Do not pass private keys or write-capable tokens to branch-controlled composite actions or Docker builds. Use narrowly scoped, short-lived credentials for the remaining publish steps.

- Line 23: Update the troubleshooting guide’s default agent_mump2p_port
references, including the health-check and firewall instructions, from 43213 to
33213 to match AgentMumP2PPort; retain 43213 only where explicitly presented as
a sample override.

In `@pkg/service/mum_p2p/transport_test.go`:
- Around line 82-87: Update the test setup around NewNode to allocate a port
validated as available for both TCP and UDP, or use ephemeral listener ports and
dial the resulting listener address. Remove the TCP-only listen-and-close
allocation so the test remains deterministic and avoids bind races.

In `@pkg/utils/addresses.go`:
- Around line 16-21: Add focused tests for BuildQUICTCPAddr covering IPv4-only,
IPv6-only, and dual-stack inputs. Assert that every configured address produces
both TCP and udp/.../quic-v1 entries, including the combined output returned by
the function.

granting GITHUB_TOKEN only contents: read, while leaving the separately
