chore: relicense HDP from CC BY 4.0 to Apache License 2.0 - #27
Merged
Conversation
Switch the monorepo license from Creative Commons Attribution 4.0 to Apache License 2.0 to provide an explicit patent grant and align with conventions common in the AI/agent tooling ecosystem (LangChain, LlamaIndex, CrewAI, AutoGen). - Replace LICENSE with full Apache 2.0 text (Helixar Limited, 2026) - Update root README badge and License section - Flip license field in every package.json and pyproject.toml across packages/* from CC-BY-4.0 to Apache-2.0 - Update License section in per-package READMEs - Remove packages/hdp-grok/LICENSE (stale CC BY 4.0 text — the root LICENSE now applies uniformly across all packages) - Regenerate package-lock.json so workspace license entries match No source/code logic changes — documentation and metadata only.

Summary
Relicenses the HDP monorepo from Creative Commons Attribution 4.0 (CC BY 4.0) to the Apache License 2.0.
Apache 2.0 is the more appropriate choice for a software project: it includes an explicit patent grant, a contribution clause, and a well-understood set of redistribution terms — all things CC BY was never designed to cover. It's also the prevailing license across the AI/agent tooling ecosystem HDP integrates with (LangChain, LlamaIndex, CrewAI, AutoGen), which makes downstream integration and redistribution friction-free.
