Takeaway: Next time I'd nail down the SvelteKit server-fetch/env-var pattern up front instead of letting the agent iterate through three different fixes for the same root cause.

Takeaway: Next time I'd tell it upfront to use a single server-side fetch helper (or a proxy +server.ts route) instead of env vars for backend URLs, since that's what ate an hour of back-and-forth.
Takeaway: Next time I'd state upfront that adding LocalDateTime support might force a toolchain migration, since that single sub-task turned into a Java 25/Gradle 9.5.1 bump that could have been scoped separately.
