" summary

A set of Summer of Code projects deliver concrete tools and prototypes: a new compiler flag f-diagnostics-as-json that emits one-line JSON diagnostics plus a formal JSON schema (merge request open); modularized Calligraphy with CLI/GUI work but ongoing GHC-compat issues; a JSON intermediate representation proposal to decouple Haddock from GHC; Cabal gains structured errors with cabalNNN codes to join the Haskell error index; HLS adds resolve across completions/code actions and ~5,000 edits; go-to-definition for external deps by exporting hi files in cabal store (needs recent cabal/GHC support).
