ADR-0012: Apache-2.0 license; no AGPL hard dependencies

• Status: Accepted
• Date: 2026-07-30

Context

Holesail (ideal TCP tunnel) is AGPL-3.0. PearDock aligns AGPL with Holesail. Flying Jib targets Holepunch-friendly Apache-2.0 distribution and contribution.

Decision

1. Project license: Apache-2.0.
2. Do not add AGPL packages (including holesail) as runtime hard dependencies.
3. Reimplement needed tunnel behavior with HyperDHT under Apache-2.0 (ADR-0006).
4. Any future AGPL exception requires a superseding ADR and explicit owner approval.

Consequences

Positive

• Clear contribution and redistribution story
• Aligns with most Holepunch modules

Negative / tradeoffs

• Cannot drop in holesail; must maintain thin tunnel code
• Must watch transitive licenses (Prismarine is generally permissive — verify on install)

Follow-ups

• Phase 5 optional license CI check
• SBOM note when packaging
