Context
@couimet/detailed-result was just published (PR #93). It provides a DetailedResult<T, E> type for explicit error handling, paired with @couimet/detailed-error.
RangeLink's production source doesn't currently use a Result type, but the demo files (demo/01-basic-usage/paymentHandler.v1.ts, paymentHandler.v2.ts) hand-roll a PaymentResult interface with { success: boolean; ... } — a pattern that DetailedResult standardises.
What to do
- Add
@couimet/detailed-result to dependencies (and @couimet/detailed-error if not already present) in package.json
- Update the demo payment handlers to return
DetailedResult instead of the ad-hoc PaymentResult interface
- Consider adopting
DetailedResult in any production error-handling paths that return success/failure discriminated unions
- Run
pnpm install, pnpm build, pnpm test, and pnpm typecheck to verify
This is lower-priority than the rabbit-maximizer migration — the demo files are educational, and the production code doesn't duplicate a local Result. The issue is primarily to track the opportunity.
