GFRandClaude Sonnet 5 d0bb1a31e8 fix(recurring): include amount in manual recurring duplicate check (#2972)
* fix(recurring): include amount in manual recurring duplicate check

TransactionsController#mark_as_recurring blocked a second manual
recurring transaction whenever an existing one shared the same
account + payee name/merchant + currency, even when the amount
differed -- stricter than the DB unique indexes
(idx_recurring_txns_acct_name / idx_recurring_txns_acct_merchant),
RecurringTransaction::Identifier's own grouping key, and the
equivalent check already used in TransfersController#mark_as_recurring.

Add amount to the duplicate lookup so two distinct recurring payments
to the same payee at different amounts are both allowed, while an
exact duplicate is still blocked. Also rescue
ActiveRecord::RecordNotUnique around the create call so a race between
the pre-check and the DB constraint (e.g. a double-submit) surfaces
the same friendly "already exists" message instead of a generic
error, mirroring the existing race-handling pattern in
RecurringTransaction::Identifier.

Fixes #2936

* fix(recurring): don't blend distinct charge amounts into variance band

Once two manual recurring rows with the same payee/different amounts
can coexist (this PR), RecurringTransaction.create_from_transaction's
variance-band discovery still matched historical entries only by
account/payee/currency/day-window -- never by amount -- so it could
blend genuinely unrelated charges (e.g. a fee + a due from the same
merchant, same day) into one row's expected_amount_min/max/avg.
Flagged by Codex review on this PR.

Confirmed this is not hypothetical: two real production transactions
(3.00 and 19.68, same merchant, same day) got blended into a single
recurring row showing a fabricated "11.34" projected amount that
matches neither real transaction.

The same unfiltered matching independently exists in
RecurringTransaction::Identifier#manual_recurring_matches_entry?,
which periodically re-derives every manual recurring row's variance
after each sync (via IdentifyRecurringTransactionsJob). Both call
sites needed the fix together, or the job would silently re-blend
amounts on the next sync.

Add RecurringTransaction.amount_within_variance_band?(candidate,
anchor, ratio: 2) -- a candidate only counts as "the same fluctuating
payment" if it's within 2x (double/half) of the anchor. Anchored on
the target amount (not pairwise) so unrelated charges can't chain
together; ratio-based (not %-of-target-with-floor) so it's
scale-invariant and handles signed (expense) amounts correctly.
Threshold checked against real data: existing variance test fixtures
sit at ~1.2-1.3x (must stay included), the real corrupted case sits
at ~6.6x (must be excluded) -- 2x leaves comfortable margin on both
sides.

Wire this into find_matching_transaction_entries/
find_matching_transaction_amounts (SQL-level filter, same pattern as
the existing day-of-month bounds) and into
manual_recurring_matches_entry?. amount_window_scope/
matching_transactions and create_from_transfer need no changes --
confirmed by reading: the former only consumes an already-computed
band, the latter never does variance discovery at all.

Does not touch any already-corrupted production data -- deliberately
out of scope, discussed separately.

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.

Forking and Attribution

This repo is a community fork of the archived Maybe Finance repo. Youre free to fork it under the AGPLv3 license — but wed love it if you stuck around and contributed here instead.

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.
