walkerOS v4.0.2
Changes
Move from packages/web/destinations/demo to packages/destinations/demo so
the package can serve web and server flows from a single location, alongside
packages/transformers/. The published package name and exports are unchanged;
only the in-repo path moves. walkerOS.platform widens from ["web"] to
["web", "server"]. No consumer code changes required.
Rename routing types: NextRule to Route, Next to RouteSpec (Zod schemas
and MatcherNext* IDs renamed in step). Widen Flow.*.before/next to
RouteSpec so Route[] conditional routing type-checks at the JSON layer. Fix
the CLI bundler dropping Route[] data via a narrowing cast on the inline path.
Hard cut, no aliases; flow.json shape unchanged.
