All three failed on main for two inherited reasons: TS 6 errors on the baseUrl deprecation from tsconfig.base.json, and the per-library rootDir excludes the sibling sources that type-specs import through path mappings. Both are scoped to the type-tests configs — putting ignoreDeprecations in tsconfig.base.json breaks the library builds, whose compiler rejects the option with TS5103.

All three
type-teststargets (chat,ag-ui,langgraph) have been failing on main, so the type-level assertions they exist to enforce were not being checked. Three separate agents hit this last week and had to verify their type assertions by hand.Two inherited causes, both fixed only inside the type-tests configs:
TS5101—tsconfig.base.jsonsetsbaseUrl, which TypeScript 6 reports as deprecated. These targets invoke the workspacetsc(6.0.2), newer than the compilers the library builds use. PuttingignoreDeprecationsintsconfig.base.jsoninstead breaks every library build withTS5103: Invalid value for '--ignoreDeprecations', so it is scoped to the three configs that need it.TS6059— each library'srootDiris its own directory, but type-specs import sibling libraries throughtsconfigpath mappings. WithnoEmit,rootDironly has to be wide enough to contain what is checked.Dropping
baseUrlaltogether is the real migration before TypeScript 7, but it changes resolution for every project in the workspace and does not belong in this fix.Verification:
