Installs @total-typescript/ts-reset 0.6.1 as a dev-dependency in
apps/portal/ and apps/app/. Patches TypeScript's loosest default
types: Array.filter(Boolean) returns non-nullable, JSON.parse
returns unknown, fetch().json() returns unknown, Map.get() strict,
etc.
Configuration: src/reset.d.ts in each SPA imports the reset. Both
tsconfig.json files already include ./src/**/* so the .d.ts is
picked up automatically — no tsconfig edits needed.
Issues surfaced during install:
- apps/app — 0 pre-install tsc errors in own code; install
surfaced 2 errors in src/stores/useImpersonationStore.ts
(both from JSON.parse on sessionStorage content returning
unknown instead of any). Fixed inline at lines 19 + 123 via
`as ImpersonationState` casts that make the existing
trust-in-sessionStorage explicit. Backlog entry
TECH-TS-IMPERSONATION tracks proper runtime shape validation.
- apps/portal — 22 pre-existing tsc errors in own code (mostly
tiptap editor components — tracked as TECH-TS-PORTAL-TSC,
unrelated to ts-reset). Zero new errors in portal's own code.
4 additional errors surfaced in tiptap's uncompiled node_modules
.ts sources (third-party); left as-is.
Neither SPA achieves `tsc --noEmit` clean today — pre-existing
state unrelated to this work package. Build + vitest are the
actual working gates and both remain green:
- apps/portal: vitest 113/113 passing; production build succeeds
- apps/app: (no vitest setup — tracked as TECH-APP-VITEST);
production build succeeds
Documentation: /dev-docs/FRONTEND-TOOLING.md added; CLAUDE.md
quality-gates updated.
Backlog: TECH-TS-IMPERSONATION (runtime validation of stored
impersonation state), TECH-TS-PORTAL-TSC (pre-existing portal tsc
errors), TECH-APP-VITEST (Vitest coverage for apps/app).
No production behavior change.
