* 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.
* feat(balance): persist daily balance snapshots for linked accounts (SnapTrade, Plaid)
When updating a linked account's balance, the previous day's current_anchor
is now preserved as a reconciliation valuation before being replaced. This
creates a chain of API-reported balance waypoints over time. The
ReverseCalculator has been updated to treat these reconciliation valuations
as reset points during reverse syncs, ensuring historical balances accurately
reflect the known API-reported values even with incomplete transaction history.
* fix(balance): don't treat current_anchor as reconciliation waypoint
The ReverseCalculator was incorrectly treating the current_anchor valuation
(on Date.current) as a reconciliation waypoint, causing it to reset the
balance and ignore same-day transactions. This fix adds a check to ensure
only true reconciliation entries (entryable.reconciliation?) trigger the
reset behavior.
Additionally, set_current_balance_for_linked_account is now wrapped in a
database transaction to ensure atomicity when preserving stale anchors and
creating/updating the current anchor. Logging has been improved to use
debug level for amount details.
A regression test was added to verify that same-day flows are correctly
processed when a current_anchor exists on the current date.
* test(account): ensure preserved valuations use correct historical date
Add validation that valuation entries created during balance
preservation are dated as of yesterday. This prevents future-dated
entries and maintains temporal accuracy in financial snapshots.
* refactor: remove redundant transaction block and unused method comment in current balance manager
* refactor(account): remove redundant valuations reload in CurrentBalanceManager and add regression test for consecutive reconciliation waypoints
* refactor: remove redundant transaction block and update anchor rotation log to include entry ID
