X_TEST_TYPECHECK_REGRESSED
Means
a package's own tests carry more tsc errors than the ratchet pins
Typical cause
every package tsconfig.json excludes src/**/*.test.ts, so bun run typecheck reads none of them and the gate was green over all 984 of them (find packages -path '*/src/*' -name '*.test.ts*' -not -path '*/dist/*' \| wc -l, As of 2026-08). tsconfig.tests.json is the program that compiles them, noEmit. The count may only fall
Fix
fix the diagnostic the finding names — bun run scripts/test-typecheck-gate.ts --json prints every one — or raise that package's entry in scripts/lib/test-typecheck-pins.ts deliberately, which is a decision and not a default
