Problem
The product motivation and original problem statement still require Fernando’s confirmation.
Constraints
Evidence is mapped for exact money arithmetic, household isolation, same-origin operation, and mobile accessibility.
Fernando’s contribution
The exact authorship scope remains pending Fernando’s confirmation and will not be inferred from Git history.
Approach
The repository confirms a Next.js App Router monolith with thin route handlers, framework-agnostic services, Prisma, and PostgreSQL.
Important decisions
The evidence set covers httpOnly cookie sessions, integer-cent arithmetic, automated revision history, optimistic concurrency, and database balance aggregation.
Current outcome
A public repository and live demo are mapped. Release wording and screenshots require a final freshness and privacy review.
Lessons
Personal reflection remains pending Fernando’s confirmation.
Next steps
Future work remains pending Fernando’s confirmation and will be labelled explicitly as future work.
