Standard Grant: S5 Gateway & TypeScript Client

Hi John,

Thank you for reviewing my progress report. I’ll clarify what was accomplished and the current approach:

The milestone called for “project set-up & design” and that’s exactly what was delivered in detail:

Repository Structure & Approach: After consulting with Redsolver and the community, we determined that direct contributions to the existing s5.js repository will be more effective than creating separate wrapper repositories. This represents better technical alignment with the S5 ecosystem.
Toolchain & Development Approach: Established TypeScript development environment with TDD methodology. For the WASM components (months 4-5), I’ll create a separate Rust repository with appropriate CI/CD for WASM compilation.
Code Contribution Guidelines: Working directly with Redsolver to ensure contributions align with s5.js project standards and S5 v1 specification compliance.

Current Month’s Focus:
Month 2 will deliver the first working code: DirV1 serialisation/deserialisation and basic path-based operations, as outlined in my technical design.
The design work completed last month was to ensure the implementation will be architecturally sound and compatible with the broader S5 ecosystem.

Repository Links:
Implementation work will be submitted as pull requests to s5-dev/s5.js. The Rust WASM components will have their own repository when we reach months 4-5.

Hope that clarifies,
Jules
