typecheck.mjs

// Wrapper around `tsc --noEmit` that filters out two classes of upstream
// errors we can't fix from this repo:
//
// 1. node_modules/pilotui/* — pilotui's package.json points `exports.types`
//    at raw TS source, so tsc follows into pilotui/src/vue.ts which has a
//    mismatched plugin signature against vue3-perfect-scrollbar.
//
// 2. ../dashboard-app/* — src/stores/profile.ts imports types from the
//    sibling dashboard-app repo (see CLAUDE.md). dashboard-app's frontend
//    types re-export from server-side TS that depends on mongoose / stripe
//    / @modular-rest/server — installed in dashboard-app's own
//    node_modules but not in ours. CI clones dashboard-app without
//    installing its deps; locally maintainers usually have them. Either
//    way, those errors aren't actionable from here.
//
// On clean runs we print only a short summary so GitHub's log parser
// doesn't surface the suppressed errors as red `Error:` annotations.
// Real errors in our own code still print the full tsc output and fail.
