Defined in: model/errors.ts:39

Every code a consumer can catch, one closed union (#333, narrowed by #380). Every super(…) below writes its literal satisfies BuiltInThrownCode, so super('invlid-instant') is a compile error rather than a shipped typo.

satisfies at each site, and not a narrower base class the built-ins extend. That base reaches the published .d.ts through 42 extends clauses, so API Extractor asks for it to be exported — and a class whose one job is to narrow this repo's codes must not become a class a consumer can extend. satisfies checks the same literal, costs nothing at runtime, and leaves FreeGanttError the one base a consumer ever sees.

Every code here has a FreeGanttError subclass a consumer can catch. A code that reports an internal invariant no consumer can reach is InternalThrownCode instead — it stays off this union, and off switch (error.code)'s autocomplete, because a consumer cannot act on it (#380).

A thrown code is not a report code. This names what an exception carries; error-report.ts's BuiltInReportCode names what a recovered fault reports. Two codes sit in both, and errors.test.ts holds that overlap to exactly two.
