CrossDrain 2620653b2a fix(balance): derive waypoint start from day's flows to prevent double-counting and phantom bumps (#2031)
* fix(balance): fix double-counting on reconciliation waypoints with same-day transactions

Waypoint branch was setting start = end = waypoint and passing real flows
to build_balance. Since end_balance is a PG generated column that recomputes
from flows, transactions were double-counted on waypoint days and the prior
gap day inherited a phantom jump.

Fix: pin only the end to the API value, derive start from the day's own
flows (same as current_anchor). Transaction attributed once, gap day
correct, investment cash/holdings split correct.

Adds regression test + GUI breakdown test verified against real PG columns
through UI::Account::BalanceReconciliation.

Fixes #2007.

* test(balance): add investment waypoint regression test

Covers reconciliation waypoint + same-day trade on investment accounts:
end_balance must match API-reported total (not double-count trade flows),
cash/non-cash flows must be preserved, and gap day total must be correct.

Sure: The personal finance app for everyone

Get involved: DiscordWebsiteIssues

Important

This repository is a community fork of the now-abandoned Maybe Finance project.
Learn more in their final release doc.

Backstory

The Maybe Finance (archived/abandoned repo) team spent most of 20212022 building a full-featured personal finance and wealth management app. It even included an “Ask an Advisor” feature that connected users with a real CFP/CFA — all included with your subscription.

The business end of things didn't work out, and so they stopped developing the app in mid-2023.

After spending nearly $1 million on development (employees, contractors, data providers, infra, etc.), the team open-sourced the app. Their goal was to let users self-host it for free — and eventually launch a hosted version for a small fee.

They actually did launch that hosted version … briefly.

That also didnt work out — at least not as a sustainable B2C business — so now here we are: hosting a community-maintained fork to keep the codebase alive and see where this can go next.

Join us!

Hosting Sure

Sure is a fully working personal finance app that can be self hosted with Docker.

Performance Issues

With data-heavy apps, inevitably, there are performance issues. We've set up a public dashboard showing the problematic requests seen on the demo site, along with the stacktraces to help debug them.
