Bug fix

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.

Feature

Separate signed-out discovery from signed-in onboarding

Introduces a marketing landing page for signed-out visitors while retaining the full application for authenticated users. The onboarding tour now waits for Clerk authentication to load and requires sign-in before checking whether it should appear.

Testing

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.

§05Method

i.

Source of truth

A job checks GitHub every ten minutes for pull requests authored by @aryanbarde80 with merged status. Nothing is entered by hand; unmerged or closed work never appears. New results appear on this page live, without a reload.

ii.

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.

iii.

Editorial bar

Trivial changes (typos, version bumps, formatting) stay on the record but are not written up. Commits to my own repositories are excluded from the counts.
