Keep the app usable when localStorage throws
Added a shared storage wrapper that preserves theme and sidebar preferences in page memory when browser storage fails. Guarded the pre-hydration theme read so blocked storage falls back to the OS preference.
Test processor schema validation and union routing
Adds a dedicated Vitest suite for the Zod schemas in Mastra's processor step schema module. The tests exercise runtime validation without changing production behavior or adding dependencies.
Test shared vector validation contracts in Mastra core
Adds a Vitest suite for four shared vector validation helpers. The tests cover input structure, numeric validity, MastraError contracts, and the optional value-checking behavior of validateUpsert.

§04Where the work landed
§05Method
Source of truth. An hourly job queries GitHub for pull requests authored by @aryanbarde80 with merged status. Nothing is entered by hand; unmerged or closed work never appears.
Case studies. Each new merge is read — title, description and diff — by a language model instructed to describe only what the code shows. No invented metrics or impact claims.
Editorial bar. Trivial changes (typos, version bumps, formatting) stay on the record above but are not written up. Commits to my own repositories are excluded from the counts.
