Count hand-valued assets into the wealth figure
A wealth figure that ignores the house is not a wealth figure. Assets without a market feed - a house, a car, a private loan - are now added by hand on the Wealth page with a stated value, a currency and the day the estimate was made; a negative value records a liability. They are registry entities in assets.finance like everything else, join the per-currency totals immediately, and a currency held only in an asset earns its own line. |

Value positions from a daily price feed
A position was a share count. An instrument now carries a market symbol and the last close fetched for it, so Wealth and the dashboard report cash plus market value instead of cash alone. The symbol is chosen by hand and never derived: one ISIN lists on several exchanges in different currencies, and a price from the wrong listing misstates wealth without failing any check. The refresh refuses a quote whose currency differs from the instrument's, keeps the previous quote when a symbol cannot be priced, and counts an instrument with no symbol as unpriced - naming it in a check and leaving it out of every total, because cost is not value. The quote belongs to the job: saving an instrument can neither set nor erase it, and changing the symbol discards it. Two things the provider forced. It answers HTTP 429 to every request whose User-Agent names a programming language, so the client identifies as a browser; without that header the first call of the day fails. Its closes are 32-bit floats widened to 64 - 165.26 arrives as 165.25999450683594 - so a figure is rounded to seven significant digits, which is what 24 mantissa bits carry; eight would have stored 165.25999 as a price. Accepted quotes are written in one commit against a revision re-read after the fetches, and nothing is committed when no quote changed. The automatic run starts shortly after launch and repeats daily on its own timer, so a sync backoff cannot delay it and prices arrive with no bank connected. Verified against live quotes end to end: 80 shares at 125.45 and 40 at 165.26 on 6000.00 cash report 22646.40 with one holding named as unpriced; giving that holding a symbol through the UI moves the figure to 23530.50, and a second refresh leaves the revision untouched. |

Import Trade Republic exports, whose conventions invert Scalable's
A second broker export is recognized locally, by its full column set, and read through the same pipeline: detection and parsing now dispatch on the format, so the upload path, the review dialog, deduplication, the journal and the Wealth report are unchanged. Its nine row types cover cash transfers, interest, dividends, tax settlements and trades in funds, shares and crypto; none of them moves a position without moving cash, so the cash-neutral class that Scalable's corporate actions belong to does not arise here. Three of its conventions are the opposite of the export already supported, and reading any of them the other way round moves money. Fee and tax are the signed adjustments it made to the cash rather than deductions from a gross, so a one euro order fee arrives as -1.00 and is negated at import; the journal keeps one convention and the domain never learns that two exist. A cash row's amount is the gross, not the net, so interest of 16.46 with -4.33 of tax credits 12.13 - where the other export states its cash already net and its tax is recorded and never applied. Whether a cash row carries a gross now decides which of those it was, which also makes the first kind's settlement checkable and stops the Wealth report from claiming a figure was left unapplied when it was not. And a TAX_OPTIMIZATION row puts zero in the amount column and its money in the tax column, signed both ways: read as cash, all six in a real export move nothing. Two more rows lie about their own columns. A dividend fills the share column with the holding the dividend was paid on, not with a position change, so adding it would double the holding. Crypto carries a bare ticker in the symbol column and its ISIN-shaped identifier only in the description, so the identifier is taken from the symbol when that is an ISIN and otherwise from the one the description names; a position row resolving to neither is refused rather than attached to a guess. The shares-times-price check now holds a gross to the precision the export stated it at rather than to four places. This export prints the notional rounded to cents, and 29 of 59 real trades do not land on a whole cent: demanding exactness rejected half a portfolio. One unit of the stated precision is still four orders of magnitude tighter than the misplaced separator the check exists to catch, and where an export prints the full product the check stays exact. A unit price moves from money to the eight-place quantity type, because a crypto price is quoted to six and rounding it would break the check the amount is verified against. Trailing zeros are dropped before any precision test: this export pads a six-place price to ten, and the padding would otherwise exhaust the precision the value needs. A transfer's counterparty comes from the export's own IBAN column when it has one, from the IBAN the description names in parentheses when it does not, and from the account's configured settlement IBAN when neither names anything. Free text contributes only a value shaped like an IBAN. Without this, 108 transfers stay unpaired and their bank-side counterparts read as spending and income. Verified end to end against a real export: 26 rows import to a cash balance of 32187.02 matching the figure computed by hand from the source rows, all four positions close at exactly zero, and every trade satisfies its own arithmetic. |

Track investments as broker facts with a position leg
An account now has a kind, and an investment account holds positions as well as
cash. A broker row is not a new entity: it is a bank fact with an optional
position leg, so deduplication, the journal, fact immutability, the DuckDB
projection and the transactions view carry it unchanged. Facts.Amount stays the
cash leg and is zero on the rows that move only a position.
Scalable Capital exports are recognized locally as a fourth format, read by
their own parser because a column mapping cannot describe them: the amount
column is settled cash on a cash row, a gross to be netted on a trade, and a
position valuation that must never touch cash on a corporate action or a depot
transfer. A cash amount is already net of the tax the broker withheld or
refunded, so that tax is recorded on the fact and never subtracted a second
time; treating a corporate action's valuation as money conjures cash, and a
depot switch would do it once per instrument. The share column is signed only
for those two types, so buys and sells take their direction from the type. Every
security row is checked against shares times price at 128-bit width, because a
lost decimal separator survives every other check. An unknown status, type or
assetType, a foreign currency, a missing ISIN, or one failed check rejects the
whole file with the record number.
Instruments live in instruments.finance, keyed by ISIN with an ID derived from
it, so re-importing never registers a security twice. One ISIN appears under
several broker descriptions over the years and sometimes under the ISIN itself:
the most recent real description names it, and an import never renames one that
already exists. A broker also reuses a single reference across every leg of one
event, so transaction identity includes the event and its instrument.
domain.Fallback returns kind "investment" for any fact carrying a position leg,
so no broker row reaches the sign-based branch. That single rule is what stops
an unmatched deposit from counting as income and a broker fee from counting as
household spending; the monthly PRIME fee and its matching credit now cancel in
clearing:investments with no configuration at all. Investment rows are excluded
from spending analytics, from bulk reclassification and from the model, exactly
as transfers are.
Equal competing transfers are paired instead of skipped. Every connected
component of the candidate graph is a complete bipartite graph between two fixed
accounts at one amount and currency, so every pairing produces the same
accounts, kinds and postings and only the displayed counterpart differs.
Refusing to choose was the expensive option: both legs fell through to the
sign-based fallback and appeared as spending and income that never happened.
Pairing follows the nearest booking date, then the transaction ID, so iteration
order decides nothing. POST /api/transactions/{id}/transfer rewrites the old and
the new pair in one commit, because reciprocity is validated and a half-applied
link is an invalid dataset, and the matcher now skips any record classified
manually so a hand-made link or unlink outlives the next import.
Wealth reports each account's cash and positions from the journal rather than
the index, with named checks - row arithmetic, cash never negative, holdings
never negative - because it exists to be compared against the figures a broker
shows on its own screen. A negative holding means the imported history is
partial. Share counts are exact to eight places; a reinvested distribution
quoted to six is rounded to money's four and the residue is reported rather than
hidden. Market prices, market value, net worth over time, FIFO lot accounting,
realised gains and currency conversion are deliberately absent.
