MattssonandClaude Fable 5 9ad3908ed0 fix(salary): skatteavdrag rounding trio (whole kronor, ,50 table pick, import prefix guard) (#1582)
* fix(salary): state percentage skatteavdrag in whole kronor (SFF 22 kap. 1 §)

calculateJamkningTax and calculateSidoinkomstTax returned öre-precision
amounts; skatteavdrag is stated in whole kronor with öretal dropped
(SFF 2011:1261 22 kap. 1 §), the same rule taxForRate already applies to
percent brackets. The two inline flat-30% branches in calculation-engine.ts
(unverified F-skatt, no-table fallback) had the same defect and now route
through calculateSidoinkomstTax.

Computed in integer öre and hundredths of a percent: flooring the raw float
product loses a whole krona when float noise lands an exact result just below
an integer (1000 * 0.007 === 6.999999999999999).

* fix(salary): pick the lower tax table at exactly ,50 per Skatteverket rule

Math.round sent a total municipal rate of 32,50 to table 33; Skatteverket's
rule is that a fractional part of at most 50 öre picks the lower table and
51 öre or more the higher. Compared in hundredths so float noise cannot
decide the boundary. Latent today (no kommun sits exactly on ,50 for 2026)
but the code now matches the comment above it, which already stated the
correct rule.

* fix(salary): reject two-week rows in the monthly tax table import

parseLine only checked position 3 for B/%, so a two-week table row (14B29)
would silently merge into the monthly fallback data if the wrong Skatteverket
file were used as input. The day-count prefix must now be 30; a 14-row throws
loudly. main() is guarded behind a direct-execution check (same pattern as
generate-crontabs.ts) so parseLine is importable by tests.

* fix(salary): truncate toward zero, not floor, in whole-krona skatteavdrag

Skeptic refutation: taxable income can go negative when deductions exceed
pay, and Math.floor rounds negatives away from zero, so a payslip 1 öre
negative would book a full krona of negative withholding
(calculateSidoinkomstTax(-0.01) gave -1 instead of -0). Öretal bortfaller
truncates toward zero: Math.trunc, with -0 normalized to 0.

MattssonandClaude Fable 5 614b7e60b9 fix(salary): apply percent brackets for monthly incomes above 80 000 kr (#1510)
* fix(salary): apply percent brackets for monthly incomes above 80 000 kr

Skatteverket's monthly tax tables switch from fixed krona amounts to
percent-of-income rows above 80 000 kr/month. The lookup only loaded the
krona ("30B") rows and clamped higher incomes to the last bracket,
under-withholding every salary above 80 000 kr (e.g. 100 000 kr, tabell
31 kolumn 1: 25 294 kr instead of 35 000 kr).

- fetch both 30B and 30% sections from the Skatteverket API; treat a
  missing section as API failure so the bundled fallback wins over
  incomplete data
- TaxTableRate is a discriminated union; percent brackets withhold
  percent of the whole monthly income, ore dropped per SFF 2011:1261
  22 kap. 1 (oretal bortfaller)
- fallback generator parses %-rows too; regenerated with 1 232 percent
  rows and a guard that every table carries both sections
- keep the old clamp only as a warn-logging last resort

* fix(salary): fail loudly on incomplete tax table data (review findings)

Address CodeRabbit and Swedish accounting review findings on #1510:

- lookupTaxAmount throws TaxTableUnavailableError when loaded brackets
  contain a gap instead of silently withholding 0
- a failed or empty pagination page fails the whole API fetch so the
  bundled fallback serves complete data
- kolumn values are parsed strictly (decimal-aware, comma accepted);
  malformed values fail the fetch instead of becoming 0 kr / 0 %
- importer rejects malformed column values instead of emitting 0
  (regenerated fallback is byte-identical)
- close the bracket gap in the calculation-engine test fixture
- clarify the ore-truncation citation and use an absolute date in
  DECISIONS.md

* fix(salary): validate income boundaries in tax table parsers

Round-2 CodeRabbit finding on #1510: income boundaries were still parsed
with parseInt, which accepts "100abc" and turns garbage into 0 or an
open-ended bracket. Both the importer and the API loader now require
digits-only boundaries; an empty upper bound is legal only on percent
rows (the open-ended top row). Malformed API data fails the fetch so the
bundled fallback runs; malformed TXT data fails the import. Regenerated
fallback is byte-identical.

Jakob WennbergandClaude Sonnet 5 ec27228a8e style: remove em/en dashes repo-wide, add CLAUDE.md rule against them (#890)
Em dashes (—) and en dashes (–) had spread across comments, docs, tests,
and a few UI strings, reading as AI-generated boilerplate rather than
house style. Replaced each with punctuation matching its context: colon
for explanatory clauses, comma for asides, plain hyphen for numeric/legal
ranges (e.g. "21-23§"), "to"/"till" for date ranges, parentheses for
paired-dash asides. messages/en.json and messages/sv.json were fixed by
hand together to keep sv/en in sync.

Left untouched where the dash is the functional subject rather than
decorative punctuation: date-range-parser.ts's separator regex,
charset-repair.ts's CP1252 byte-mapping table (and its test), the SIE
encoding mojibake docs, generic-csv.ts's minus-sign normalizer, the
agent system-prompt files that already instruct against em dashes, and
a golden iXBRL test fixture compared byte-for-byte.

Also fixes two bugs surfaced along the way: an off-by-one in
ApiKeysPanel's scope-label split (a leftover from an earlier partial
pass), and a charset-repair test that had lost the literal en-dash it
exists to verify.

Regenerated the agent atom seed migration (skills:generate) since 27
SKILL.md files changed. Added a CLAUDE.md rule against em/en dashes,
with an explicit carve-out for the functional-dash cases above.

MattssonandClaude Opus 4.8 0ca9c25aba Add/user feedback (#679)
* feat(bookkeeping): make blocked fiscal-year creation actionable

When creating a new räkenskapsår is blocked because a prior period is
still open, the "Skapa räkenskapsår" dialog no longer dead-ends on an
English toast. The API now returns the canonical bilingual error envelope
with the blocking periods (id/name/dates) under details, and the dialog
renders a Swedish panel that locks them inline (reversible locked_at) via
the existing /lock endpoint and retries creation.

The guard rule is unchanged and remains BFL-compliant: BFL 6 kap allows
löpande bokföring of the new year in parallel with the prior year's
bokslut, so a lock (not a full close) is sufficient and reversible.

- Add PERIOD_CREATE_BLOCKED_BY_OPEN_PERIODS structured error code
- Return envelope + details.blockingPeriods from the 409 (was English string)
- CreatePeriodDialog: inline "lås och skapa" panel + lock-and-retry
- Update route tests for the new envelope shape

* fix(ui): prevent mouse wheel from mutating number inputs

A focused <input type="number"> would change its value on scroll,
silently turning e.g. a 20000 salary into 19998. Blur number inputs
on wheel so the page scrolls instead of editing the value. Applied
at the Input primitive so all number fields are protected.

* feat(salary): auto-derive skattetabell and kolumn for employees

Replace the opaque manual "Skattetabell (29-42)" and "Kolumn (1-6)" inputs
on the employee form with a self-deriving flow: the user picks their
folkbokföringskommun from a searchable dropdown and the tax table fills
itself in, while the column derives from the personnummer we already collect.

- Add a searchable municipality picker (MunicipalityCombobox) backed by a
  new cached GET /api/salary/tax-tables/kommuner endpoint.
- Wrap the whole "Skatt" card in a self-contained EmployeeTaxCard used by
  both the create and edit pages, with InfoTooltips and named column options.
- deriveTaxColumn(): auto-select column 1 for under-66 employees; leave the
  ambiguous 66+ case (pension vs working senior) to a clearly-named manual
  choice.
- Fix fetchKommunTaxRates() to page through all ~1300 församling rows instead
  of a single 500-row page (which silently dropped ~200 kommuner, incl.
  Göteborg) and normalize the uppercase names to title case.

* fix(import): correct CSV amount-column guess and surface skipped rows

Manual CSV column-mapping auto-guess walked each data row right-to-left
and picked the first numeric cell as the amount, so on the common
...;Belopp;Saldo layout it grabbed the trailing running-balance column.
Extract the guess into a pure, tested suggestColumnMapping(): match
header labels first (belopp/amount -> amount, saldo/balance -> balance),
auto-fill the balance field, and fall back to value heuristics that skip
the balance column and prefer a column carrying negative values.

Also surface stats.skipped_rows + parse warnings in BankFileConfirmStep -
the manual-mapping path skips the preview step that was the only place
they showed, so skipped rows were silently dropped from view.

Add a unit test reproducing the Saldo-as-amount regression.

- Updated the invoice creation API to skip number allocation when saving as a draft.
- Introduced a new endpoint for finalizing drafts, which allocates an invoice number and emits an `invoice.created` event.
- Enhanced the UI to include a "Save as draft" button, with loading states and tooltips.
- Updated tests to cover the new draft saving and finalization logic, including race conditions for concurrent modifications.
- Added relevant error handling for draft finalization and deletion scenarios.

MattssonandClaude Opus 4.7 11621bb79f Feat/skv integration full (#284)
* feat: add script to import Skatteverket monthly tax tables as fallback TypeScript module

- Implemented a new script `import-tax-tables.ts` to parse fixed-width TXT tax tables from Skatteverket (SKV 434).
- The script generates a TypeScript module for emergency fallback when the Skatteverket open-data API is unavailable.
- Supports command-line argument for specifying the year and handles parsing of B-rows only.
- Outputs a structured TypeScript file containing tax data for specified years.

* feat: gate salary module behind dev-only flag

Temporarily disable the Lön module in production while the feature is
being completed. Sidebar entries ("Löner", "Anställda") still render but
are not clickable and show a "Kommer snart" badge. Middleware redirects
/salary* to / and returns 404 on /api/salary/* so the feature can't be
reached by direct URL. All gates check NODE_ENV === 'development' so
local dev keeps full access for continued development.
