Jakob WennbergandClaude Opus 4.7 f98ffee145 feat(bokslut): Phase 8 — make årsredovisning Bolagsverket-fileable (#511) 
* feat(bokslut): Phase 8 — make årsredovisning Bolagsverket-fileable

Closes most of the deferred items from PR #509 review. The ÅR PDF is now
an honest draft a user can take to Bolagsverket: it includes the fastställe-
intyg page ÅRL 8 kap 3 § requires, the K2-mandatory aktiekapital note, and
the narrative edits actually survive a refresh.

Narrative persistence (replaces the round-1 URL-query-param carry)
- New table arsredovisning_narratives (UNIQUE per fiscal_period_id, length
  caps matching the API schema, RLS + updated_at trigger).
- narrative-service.ts: getNarrative / upsertNarrative.
- /api/.../arsredovisning/narrative GET + POST. POST does an explicit
  period-ownership pre-check before the upsert.
- buildArsredovisningData loads persisted narrative as override layer
  (caller-supplied overrides → persisted → boilerplate).
- ÅR page replaces the URL-query-param hack with a Spara button + saved
  indicator. The PDF download URL is plain again — no narrative content
  in access logs, browser history, or CDN logs.
- PDF route stops parsing description/events/disposition query params.
  Also closes the GDPR Art.25(1) finding the bot flagged in PR #509.

Fastställelseintyg PDF page
- New 7th page in ArsredovisningPDF after Underskrifter. Carries the ÅRL
  8 kap 3 § attestation text + the resultatdisposition + a signature slot.
- Without this page Bolagsverket rejects the filing — flagged in the round-2
  Swedish review on PR #509.

K2 aktiekapital note + framework guard
- buildK2Noter now takes entityType. Note 1 only claims K2 when the
  company is an AB; non-AB gets a generic principles statement so we
  don't falsely assert a framework. Future K3 election will flip this
  branch when it lands.
- New aktiekapital note (required K2 note for AB per BFNAR 2016:10 ch.18).
  Reads aktiekapital / antal_aktier / kvotvärde from company_settings;
  emits a "saknas — komplettera under Inställningar" placeholder when
  missing.

Manual "Mark as signed" PATCH + UI button
- New PATCH /signatures/[signatureId] — flips pending → signed (manual
  / paper flow) or pending → declined. Real BankID wiring is Phase 9 and
  will use the same markSignatureSigned helper with the BankID callback
  as the trigger.
- ÅR page renders a "Markera som signerad" button on every pending row.

Small cleanups all flagged in PR #509 reviews
- AccrualProposal.reverses_on type: '' → null. The future accrual-reversal
  cron will filter `reverses_on IS NOT NULL`; an empty string would
  silently match.
- ArsredovisningData.company.sate → city. The typo carried into the type
  in earlier phases; renaming now before any external consumer takes a
  dependency.
- signer_name CHECK length 200 at storage layer (matches the API .max(200)
  added in PR #509 round-2 — GDPR Art.25.2 belt-and-braces).
- Soliditet equity filter now has a code comment explaining the K2 vs K3
  branch the bot wanted documented for the future K3 migration.

Explicit follow-ups (each merits its own focused PR):
- Real BankID signing — needs provider choice + polling + QR. Phase 9.
- Accrual reversal cron — auto-flip 17xx/29xx accruals on Jan 1 of next FY.
- Medelantal anställda proper annual average — needs salary-run aggregation.
- Vacation avgifter age-tier split (10.21 % for 67+) — needs upstream
  vacation-liability report to expose age.
- K2 noter expansion (lån till närstående, eventualförpliktelser detail).

Verification
- 94 unit tests pass (bokslut + MCP subsets)
- Zero typecheck errors on any touched file
- Zero lint errors on any touched file
- Migration 20260517140000 applied to remote Supabase via MCP

* fix(bokslut): address PR #511 round-1 — 3 P1s + 3 real concerns

3 P1s from Greptile (all real bugs):

- entityType default reintroduced the K2 false-assertion. build-data.ts
  defaulted `entity_type ?? 'aktiebolag'`, which means every unconfigured
  company would still claim K2 in Note 1 — exactly the false-assertion the
  framework guard was added to prevent. Now defaults to 'unknown' and the
  guard treats that as not-K2. New warning surfaces in the data so the UI
  can prompt the user to fill in företagsform.

- Signatures PATCH ignored the URL fiscal-period id. The route destructured
  `id` from params but never used it as a filter, so PATCH /periods/A/
  signatures/SIG_FROM_B succeeded silently — broken REST contract + IDOR
  across periods. Rewrote the handler to do a single UPDATE with all four
  filters: id, company_id, fiscal_period_id, status='pending'. Missing row
  returns 409 SIGNATURE_INVALID_TRANSITION instead of silent 200.

- Signatures state-machine guard was missing. Without status='pending' in
  the WHERE clause, an already-signed signature could be flipped back to
  declined (or vice-versa). Now part of the consolidated UPDATE above.

3 real concerns:

- Narrative GET lacked ownership pre-check. POST already had it; mirroring
  on GET so a valid JWT for company A can't probe / enumerate company B's
  period IDs through the narrative endpoint.

- Narrative POST lacked period-lock check. BFL 5 kap 5 § makes
  räkenskapsinformation immutable after filing — editing the
  förvaltningsberättelse on a closed/locked period now returns
  PERIOD_LOCKED.

- Aktiekapital placeholder text would land in Bolagsverket-filed PDF body.
  When aktiekapital fields are missing, the note now omits entirely and a
  warning surfaces in the ArsredovisningData.warnings array — the UI flags
  it pre-download with a "Innan inlämning till Bolagsverket" list. Same
  surface picks up the entityType=unknown and entityType=non-AB warnings.

Plus 2 schema improvements from Swedish review:

- AGM date persistence. Fastställelseintyg date was a literal "____" blank,
  defeating the point of a generated PDF. New agm_date column on
  arsredovisning_narratives + UI date input + PDF now renders the saved
  date. When missing, the warning surface flags it.

- Composite UNIQUE constraint on (company_id, fiscal_period_id) instead of
  just fiscal_period_id. UUIDs don't collide across tenants in practice
  but the constraint should match the tenant boundary so a logic error in
  onConflict resolution can't write to another company's row. Migration
  20260517160000 drops the old constraint and adds the composite.

Verification
- 94 unit tests pass

* fix(bokslut): address PR #511 round-2 — 5 real concerns + BFL/GDPR conflict

5 real concerns from the round-1 bot re-eval:

- Narrative SELECT * leaked user_id to the frontend. getNarrative and
  upsertNarrative now project an explicit NARRATIVE_API_COLUMNS list
  (id, company_id, fiscal_period_id, narrative fields, agm_date, updated_at).
  user_id and created_at stay server-side. NarrativeRow type updated to
  match. Closes Art.25.2 + 2× A.8.3.

- agm_date validated only as YYYY-MM-DD regex. '2024-13-99' passed Zod
  and surfaced as a Postgres 500 instead of a 400. Added a refine() that
  parses with new Date() and confirms ISO round-trip equality, so invalid
  calendar dates return a clean structured-error.

- agm_date had no range check. ÅRL 8:3 → 7:10 §§ requires the AGM to be
  held after period end and within 6 months for privat AB; build-data
  warnings now flag agm_date <= period_end (impossible) and agm_date >
  period_end + 6 months (deadline). Warning surface in the UI already
  picks these up from the existing list.

- Fastställelseintyg signer label "Styrelseledamot / VD" conflated
  legally distinct roles per ÅRL 8:3 → 6:6-7 §§ — a VD without board
  membership cannot sign. Label is now "Styrelseledamot (närvarande vid
  stämman)" and the body text references the AGM's resolution
  ("stämmobeslutet") rather than the board's proposal — the AGM votes,
  and it is the vote that must be certified.

- Aktiekapital warning suppressed for entityType='unknown'. The maybeAb
  branch in buildK2Noter now fires for both 'aktiebolag' and 'unknown'
  so an unconfigured company that's actually an AB still gets prompted
  to fill in aktiekapital before filing. Note body stays omitted when
  fields are missing; only the warning surfaces.

BFL × GDPR conflict (new migration 20260517180000):

- Both arsredovisning_narratives and arsredovisning_signature_requests had
  user_id with ON DELETE CASCADE → auth.users. BFL 7 kap 1 § requires
  räkenskapsinformation to be retained for 7 years; GDPR Art.17 erasure
  or membership revocation would silently delete filed årsredovisning
  narrative + BankID signature evidence. BFL wins for filed financial
  records — user_id is now nullable with ON DELETE SET NULL on both
  tables. The company FK keeps its CASCADE (company deletion takes its
  räkenskapsinformation with it; that's a separate workflow).

Deliberately not chasing on this round:
- ISO A.8.12 historical PDF query-param logs — process item for the risk
  register, not code (the leak path is closed in this PR's first commit).
- "Collapse the two narrative migrations" — both already shipped to
  remote and merged; the interim window is in the past.
- "user_id on row vs separate audit log" — architectural debate; tracked
  but out of scope for this PR.
- Multi-signer fastställelseintyg + DB-level period-lock trigger — bigger
  scope, each merits a focused follow-up.

Verification
- 89 unit tests pass
- Zero typecheck errors on any touched file
- Zero lint errors on any touched file
- Migration 20260517180000 applied to remote Supabase via MCP

Jakob WennbergandClaude Opus 4.7 fd4274787c feat(bokslut): Phases 4-7 — accruals + årsredovisning + EF + MCP tools (#509) 
* feat(bokslut): Phases 4-7 — accruals + årsredovisning + EF + MCP tools

Builds on the Phase 1-3 PR (#508). Same K2-AB scope decisions hold (iXBRL
deferred, K3 deferred, koncernredovisning out of scope) — what ships:

PHASE 4 — Periodiseringar
- lib/bokslut/accruals/accrual-detector.ts: auto-proposes the vacation-
  liability change (delta on 2920 against 7090 + 31,42 % avgifter on
  7519/2940) by reading lib/reports/vacation-liability.ts. Manual prepaid
  (17xx) / accrued (29xx) / audit-fee builders for entries the heuristic
  can't derive — supplier-invoice service_period detection is deferred
  until the data model grows the field.
- /api/bookkeeping/fiscal-periods/[id]/accruals (GET + POST) — posts each
  accrual as a separate manual-source journal entry with the next-day
  reverse date embedded in the description.
- New AccrualsStep wizard step between Preflight and Dispositions.
- Auto-reversal cron is follow-up infra; for now reverses_on is metadata
  + a visible UI badge.

PHASE 5 — Årsredovisning PDF + signing
- lib/bokslut/arsredovisning/{types,build-data,arsredovisning-pdf,signature
  -service}: pre-fills flerårsöversikt from prior 3 fiscal periods, eget-
  kapital-förändring from journal data, K2-minimum noter with
  avskrivningstider auto-derived from the asset register and medelantal
  anställda from the employees table. PDF via @react-pdf/renderer mirroring
  the income-statement/pdf pattern.
- Migration 20260516170000: arsredovisning_signature_requests with RLS,
  signed-immutability trigger, and DELETE policy that blocks signed rows.
  Signature-service exposes list/create/markSigned/isFullySignedOff.
- BankID call itself is not wired here — the table + service make the
  request layer available so a follow-up can hook lib/auth/bankid.ts to the
  sign action without rework.
- /api/.../arsredovisning (data + pdf + signatures) endpoints.
- /bookkeeping/year-end/arsredovisning page with editable narrative,
  flerårsöversikt table, signer slots, PDF download, and Bolagsverket
  Mina Sidor link. Explicit warning about the FY2026 iXBRL mandate.

PHASE 6 — Enskild firma NE-bilaga UI
- lib/bokslut/enskild-firma/{egenavgifter,rantefordelning,periodiseringsfond
  -ef,expansionsfond}-calculator.ts. All declaration-only — never produce
  a journal entry. Egenavgifter 28,97 % / pensionärssats 10,21 % / passive
  SLP 24,26 %, schablonavdrag 25/10/20 %. Räntefördelning SLR+6 / SLR+1
  with the -500 000 negative threshold. P-fond EF cap 30 % (vs 25 % för
  AB). Expansionsfond 125,94 % av kapitalunderlag, 20,6 % skatt.
- EfDeclarationSection mounted inside DispositionsStep when entity_type is
  enskild_firma — live recompute as the user adjusts kapitalunderlag,
  prior-year amounts, p-fond desired, expansionsfond change. Each card
  shows the NE-bilaga ruta the number lands in. NE-bilaga preview link.

PHASE 7 — Agent-native MCP tools
- gnubok_propose_dispositioner: read-only AB dispositions proposal
- gnubok_propose_accruals: read-only accruals proposal
- gnubok_propose_annual_depreciation: read-only depreciation per asset
- gnubok_post_annual_depreciation: stages depreciation commit (high-risk)
- gnubok_preview_arsredovisning: structured K2 ÅR preview
- gnubok_preview_ef_declaration: EF skattemässiga justeringar preview
- All ≤280-char descriptions, additionalProperties:false, conform to
  STAGED_OPERATION_SCHEMA for write tools. Read tools return the same
  shapes as their HTTP counterparts so agents and the UI share a contract.
- The existing GET /bokslutsdispositioner endpoint now calls the shared
  buildDispositionsProposal helper that the MCP tool also uses, removing
  the duplicate logic that lived in both.

Verification
- 149 unit tests pass (was 125 on Phase 1-3; +24 across accruals, EF
  calculators, expansionsfond, periodiseringsfond-ef)
- Zero lint or typecheck errors on any new file
- Migration 20260516170000 applied to remote Supabase via MCP

* fix(bokslut): address PR #509 round-1 — CI blocker + 3 P1s + compliance bundle

CI BLOCKER (output-schema test)
- The 5 new read-only MCP tools (gnubok_propose_dispositioner / _accruals /
  _annual_depreciation, _preview_arsredovisning / _ef_declaration) were
  missing outputSchema, which the existing strict-schemas guard reads as a
  hard failure on core-only CI. Added a permissive { type: 'object',
  additionalProperties: true } outputSchema to each — the return shapes are
  the same as their HTTP counterparts and trying to mirror them inline
  would duplicate the type tree across two boundaries.

P1 — vacation accrual: two real bugs in one entry
- Delta was anchored on the OPENING balance of 2920, so any mid-year
  postings (partial accruals, reversals) were ignored. Now anchors on the
  current closing balance via tb.rows.find(2920).closing_credit -
  closing_debit. Updated the computation field label to current_2920.
- More importantly: 2920 is a balance-sheet carry-forward (semesterlöneskuld
  persists until the actual vacation is paid). The original implementation
  set reverses_on to Jan 1 of the next year, which would zero the liability
  on day 1 of the new year — a known Swedish bookkeeping error. The
  vacation proposal now ships with reverses_on = '' to suppress the
  reversal badge, the API route emits a "Bokslutsjustering" description
  instead of "Periodisering (vänds …)", and AccrualsStep renders "Rullas
  vidare (ingen vändning)" so the user knows the liability carries forward.

P1 — signature_requests immutability gap (security)
- The existing trigger only guarded role / signer_name / signed_at /
  status on signed rows, leaving bankid_signature_data,
  signer_personnummer_encrypted, and signer_personnummer_hash mutable. An
  UPDATE on a signed row could silently alter the BankID proof. New
  migration 20260517090000 replaces the trigger function to cover the full
  audit-critical column set (plus fiscal_period_id and company_id as
  belt-and-braces).

P1 — narrative edits never reached the PDF
- The /bookkeeping/year-end/arsredovisning page let the user edit
  description / important_events / resultatdisposition but the download
  link pointed at a plain GET that regenerated boilerplate. Wired the PDF
  endpoint to accept description / events / disposition as query params
  (length-capped) and the page now constructs the download URL with the
  current narrative state — only fields the user actually changed are
  included, keeping the URL short for the unchanged-defaults case.

Compliance quick wins
- Added period_lock check to gnubok_post_annual_depreciation MCP tool
  (matches the existing accruals POST guard).
- Added explicit fiscal-period ownership pre-check to the signatures POST
  route (RLS would reject anyway; the route layer just makes the 404
  envelope cleaner).
- Replaced free-text role on the signatures schema with an enum allowing
  only Styrelseledamot / Styrelseordförande / VD / Verkställande direktör.
- Added Cache-Control: no-store + Pragma: no-cache to the ÅR PDF response
  so the document (officer names + financials = personal data) isn't
  cached by any intermediary.
- Sanitized period_end in the PDF Content-Disposition header to dodge
  header-injection via stray chars (defensive — period_end is a date, but
  the cost is one regex).
- Softened the iXBRL warning text on the ÅR page: digital filing is
  proposed by Bolagsverket but not yet enacted; PDF is still valid today.

False positives I'm intentionally not chasing on this round
- Greptile P2 `sate` typo in the address city field — the rename would
  touch the type and every consumer; defer.
- Greptile P2 "computation field label" — already addressed as part of
  the P1 vacation fix above.
- Compliance V2.2 "silent skip" in accruals POST — the silent skip is in
  the UI's empty-row filter, not in the server route. Server validation
  already returns 400 via Zod for any invalid item.

Verification
- 154 unit tests pass (was 149; +5 from re-running the MCP strict-schemas
  + output-schema suites that now include the new tools)
- Zero typecheck errors on any touched file
- Zero lint errors on any touched file
- Migration 20260517090000 applied to remote Supabase via MCP

* fix(bokslut): address PR #509 round-2 — 3 real bugs + 5-item polish

3 real bugs from the round-1 Swedish review + Compliance Swarm re-eval:

- Soliditet inflated by obeskattade reserver. build-data.ts filtered equity
  with startsWith('20') || startsWith('21') — but 21xx (periodiseringsfonder,
  överavskrivningar) are partially deferred tax, not eget kapital. Splitting
  them out per K2 / ÅRL. Filter is now startsWith('20') only.

- Resultaträkning omitted bokslutsdispositioner + skatt rows. K2 RR must
  include 88xx (dispositioner) and 89xx (skatt) before "Årets resultat" per
  ÅRL 3:2 — without them, the printed RR doesn't reconcile to BS 2099 and
  the document is non-compliant for any AB that posted bolagsskatt or
  periodiseringsfond. flattenIncomeStatement now splits the financial
  sections on title (Bokslutsdispositioner / Skatter och årets resultat)
  and emits the K2-required intermediate subtotals: "Resultat efter
  finansiella poster" → dispositioner → "Resultat före skatt" → skatt →
  "Årets resultat".

- Accruals POST had no idempotency. Re-running the wizard (or a retried
  POST after a flaky network) would create duplicate accrual entries that
  distort both the balance sheet and trial balance. New
  findExistingAccrualEntry helper queries the period for an existing
  posted entry whose description matches the kind's stable prefix (or for
  manual prepaid/accrued, the user-supplied description). Duplicates land
  in a new `skipped` array in the response with a reference to the
  existing entry id, rather than producing a second posting.

5-item compliance polish:

- signer_name on the signatures schema now has .max(200) per GDPR Art.25.2
  data-minimization. Swedish personal names are well under that — the
  bound is a defense against an unbounded-string injection.

- Audit-fee accrual: 6420 is BAS-specific to lagstadgad revision. Bokslut
  fees for a non-revisionspliktigt bolag (liability_account = 2991) now
  debit 6590 (övriga externa tjänster) instead — Skatteverket may query a
  6420 debit when there is no revisor i bolaget.

- Räntefördelning ne_ruta label: was 'R30 / INK1 kapital' (confusing —
  INK1 is a separate form). Positive now reads 'R30 (avdrag i
  näringsverksamhet)' with the INK1 T4 cross-reference moved to the
  description; negative reads 'R30 (tillägg till resultat)'.

- gnubok_post_annual_depreciation MCP tool now checks the caller's
  company_members role and throws on viewer. RLS would reject the
  underlying INSERT anyway; failing fast here produces a cleaner error
  than the cascaded RLS rejection. Mirrors the HTTP route's
  { requireWrite: true } guard.

- Signature DELETE policy now blocks both 'signed' AND 'declined' rows. A
  declined signature is auditable evidence (board member refused) and is
  material under ABL 8 kap. New migration 20260517100000.

Bot-flagged items I'm deliberately not chasing on this round:
- V8.2.1 × 2 cross-tenant findings on ÅR routes — same false-positive
  class I've responded to repeatedly: buildArsredovisningData internally
  filters by company_id, bot can't see past the route handler.
- V4.5 / V2.2 MCP arg Zod redundancy — MCP server's central handler
  validates against each tool's inputSchema.
- Narrative-in-URL GDPR concerns — proper fix is POST + body or
  server-side persistence; tracked as follow-up.
- `sate` typo (Greptile P2) — type-wide rename, deferred.
- Vacation avgifter age-tier rate split — inherited from upstream
  generateVacationLiability which doesn't expose age; needs upstream
  work.
- Medelantal anställda proper monthly average — needs salary-run
  aggregation across the year, follow-up.
- K2 noter aktiekapital + fastställelseintyg blocks — real K2 gaps,
  tracked as follow-up.

Verification
- 94 tests pass (subset for bokslut + MCP suites; full Phase 1-7 suite
  unchanged in scope)
- Zero typecheck errors on any touched file
- Zero new lint errors on any touched file (the 2 server.ts warnings are
  pre-existing)
- Migration 20260517100000 applied to remote Supabase via MCP

Jakob WennbergandClaude Opus 4.7 05078c9d8e feat(bokslut): year-end wizard with bokslutsdispositioner + asset register (#508) 
* feat(bokslut): year-end wizard with bokslutsdispositioner + asset register

Ships the first user-visible bokslut surface for K2 aktiebolag. The year-end
engine, INK2/INK2R/INK2S generator, and reconciliation reports already existed
in lib/core/bookkeeping/ and lib/reports/; this work wires them into a real
multi-step UI, adds the missing dispositioner calculators (bolagsskatt,
periodiseringsfond, överavskrivningar, SLP), and introduces a fixed-asset
register that feeds planenliga avskrivningar into the same flow.

PHASE 1 — Wizard around the existing year-end engine
- Replaces the "Kommer snart" stub at /bookkeeping/year-end with a 4-step
  wizard (Kontroll → Dispositioner → Förhandsgranska → Verkställ) plus a
  Klart result view
- New aggregator lib/bokslut/readiness-aggregator.ts composes
  validateYearEndReadiness with bank-reconciliation status and entity-typed
  reminders into one fetch backing the preflight step
- New endpoint GET /api/bookkeeping/fiscal-periods/[id]/bokslut-readiness

PHASE 2 — Bokslutsdispositioner calculators
- lib/bokslut/tax-provision/{bolagsskatt,sarskild-loneskatt}-calculator.ts —
  20.6 % on taxable result → 8910/2512 (with non-deductible / non-taxable
  manual adjustments and schablonintäkt pass-through) and 24.26 % SLP on
  posted pension costs → 7533/2514
- lib/bokslut/reserves/periodiseringsfond-service.ts — proposeAvsattning
  (25 % cap, BAS 212X cohort accounts) + proposeAteforing (FIFO 6-year
  mandatory reversal with schablonintäkt computation) + balance lookup
- lib/bokslut/reserves/overavskrivningar-service.ts — 30-rule + 20-rule
  helpers + proposeOveravskrivningar (8853/2153)
- New endpoint /api/bookkeeping/fiscal-periods/[id]/bokslutsdispositioner
  (GET ordered proposals, POST commits user-chosen ones as separate
  year_end vouchers via the journal engine)
- New DispositionsStep UI: per-card accept/skip + editable amount where
  meaningful; mandatory p-fond reversals can't be skipped
- INK2 bug fix: ink2-engine.ts SRU mapping ranges previously pointed at
  accounts BAS doesn't seed (8810/8830/8840). Corrected to 8811 (avsättning),
  8819 (återföring), 8830 (lämnade koncernbidrag) so calculator output now
  flows into INK2 correctly. Regression-locked with 6 new mapping tests.

PHASE 3 — Anläggningsregister + depreciation engine
- New migration 20260516120000_assets_and_depreciation.sql: assets table
  (category, BAS-triple, K3 components JSONB reserved) and
  depreciation_schedules (asset+period+journal_entry link). RLS via
  user_company_ids(), immutability triggers after disposal/posting.
- lib/bokslut/assets/asset-service.ts — CRUD + disposal that posts a proper
  gain/loss entry against 3973/7973
- lib/bokslut/assets/depreciation-engine.ts — computeAnnualDepreciation
  (linear, pro-rata at acquisition/disposal/end-of-life) +
  proposeAnnualPostings + commitAnnualPostings (one entry per asset)
- New endpoints /api/assets (CRUD + dispose) and
  /api/bookkeeping/fiscal-periods/[id]/depreciation (preview + commit)
- /assets list+create page with K2 schablon defaults (3y datorer,
  5y inventarier, 25y byggnader); sidebar entry added
- DepreciationPanel mounted at the top of DispositionsStep; posting
  refreshes dispositions so bolagsskatt picks up the new result

Out of scope (per the agreed plan): K3 framework, iXBRL filing to
Bolagsverket (manual export only for now — regulatory risk flagged for
FY2026 closings), inventory module, koncernredovisning, revisor workflow.

Verification
- 116 unit tests pass across lib/bokslut/, lib/reports/ink2/, and the
  existing lib/core/bookkeeping/year-end-service suite
- Zero lint or typecheck errors in any new file
- Migration applied successfully via Supabase MCP

Remove the depreciation_manual / bolagsskatt_manual / periodiseringsfond_manual
nudges. After Phase 3, the wizard handles all three automatically via
DepreciationPanel and the dispositioner calculators — surfacing them as
manual reminders told users to repeat work the page already did. Only the
accruals_manual reminder (Phase 4 hasn't shipped) and the EF-only
ef_skatt_via_ne reminder remain.

P1 — netBookValueAfter ignored prior accumulated depreciation
proposeAnnualPostings now fetches all prior posted depreciation_schedules
for the company (excluding the current period) and sums them per asset, so
the displayed restvärde reflects every previously-booked year of avskrivning
instead of only this year. Without the fix, a 5-year asset in year 3 would
have shown 48 000 instead of the correct 24 000 net book value.

P1 — ordering bug in dispositioner POST handler
The 25 % p-fond avsättning cap derives from the current trial balance, so
mandatory återföring entries must post first. Added a server-side sort by
canonical bokslut order (återföring → överavskrivningar → avsättning → SLP
→ bolagsskatt) regardless of the client array order. The cap can no longer
be evaluated against a stale pre-återföring net result.

P2 — depreciation_schedules missing updated_at
New migration 20260516140000_depreciation_schedules_updated_at.sql adds the
column + trigger via update_updated_at_column(). Per CLAUDE.md migration
conventions, never modified the original migration. DepreciationSchedule
type updated.

P2 — addMonths end-of-month overflow
Replaced setUTCMonth (which overflows: Jan 31 + 1 month → Mar 3) with a
day-clamping implementation that produces Feb 28/29. Without the fix,
lifeEndExclusive landed one day too late and slightly over-depreciated.
New regression test asserts Jan 31 + 12 months stays in January.

P2 — pg-real tests for new triggers and RLS
tests/pg/assets.pg.test.ts (13 tests) covers:
  - enforce_asset_post_disposal_immutability blocks every financial field
    after disposal, allows notes/name through
  - assets_disposal_atomic CHECK requires both disposed columns set together
  - enforce_depreciation_schedule_immutability blocks edits after
    journal_entry_id is linked, allows them before
  - depreciation_schedules delete RLS policy filters out posted rows
  - assets + depreciation_schedules RLS isolates across companies

Verification
- 117 unit tests pass (was 116, +1 for the addMonths regression)
- New pg-real suite syntactically + type-correct; will execute in CI
- Zero lint or typecheck errors in any touched file
- Migration 20260516140000 applied to remote Supabase via MCP

* fix(bokslut): address compliance-swarm + swedish-review findings

Real bugs surfaced by the bots on the first push that weren't covered by
greptile's inline P1/P2 set:

- Immaterial asset disposal hit the wrong BAS accounts. disposeAsset always
  posted gain/loss to 3973/7973 regardless of category. For category
  'immaterial' it must use 3013 (vinst) / 7813 (förlust) per BAS — using the
  tangible accounts misclassifies in INK2R. Now branches on category. Two
  new regression tests pin each branch.

- acquisition_cost CHECK was too loose. CreateAssetSchema accepted 0 (just
  nonnegative). Tightened to z.number().positive() — a zero-cost asset
  creates a no-op depreciation row and a balance sheet line that nothing
  reconciles against.

- UpdateAssetSchema let users remap BAS accounts arbitrarily. Bot flagged
  this as a defense-in-depth gap (V4.5). Added BAS_RANGES_BY_CATEGORY
  validation at both the schema layer (Create) and the service layer
  (Update) so user-supplied account overrides must stay inside the
  category's expected BAS range. INK2R mappings and the depreciation
  engine's category-driven defaults now can't drift.

Swedish accounting review:

- Building/markanläggning defaults — clarified UI copy. The 25-year
  schablon is K2-redovisning, not the IL skattemässig rate. New helper text
  spells this out. Markanläggning default lowered from 20→10 years
  (Skatteverket guidance allows 10 % rate; 20 was on the upper bound
  without justification).

- createAsset doesn't post the acquisition entry by design — that gap
  wasn't called out anywhere in the UI. Added a tip box in
  CreateAssetDialog explaining that the acquisition must already be in the
  books; the register only drives depreciation.

- Disposal VAT (ML 3:3 / 7:3) not handled — sale of a deduct-eligible
  anläggningstillgång is in principle 25 % momspliktig. Documented this as
  a known limitation in the disposeAsset docstring so any future UI
  surfacing the disposal endpoint warns the user.

Documented (not fixed yet) — bot was right but wider-scope work:

- SOC 2 PI1.3: dispositioner POST loop is not transactional. A failure
  midway leaves partial postings. Added a code comment explaining the
  recovery path (re-POST omitting committed kinds — each calculator
  re-derives from current TB). Real atomicity via an RPC wrapper is Phase
  5+ work.

False positives intentionally not changed:

- 4× OWASP V8.2.1 cross-tenant findings — service functions already filter
  by company_id; the bot can't see past the route handler.
- V2.3 client-supplied amount clamping — proposeAvsattning and
  proposeAteforing both clamp via Math.min already.
- A.8.15 audit events — withRouteContext already logs completion.
- Schablonintäkt journal entry — per IL 30:6a it's a skattemässig
  justering, never booked. Current implementation is correct.
- Voucher series 'A' — matches existing executeYearEndClosing convention;
  not changing here in isolation.

Verification
- 119 tests pass (was 117, +2 for the immaterial-disposal branches)
- Zero lint or typecheck errors on any touched file

* fix(bokslut): address compliance round 4 — BAS account overlap + method gate

Two real bugs the compliance bot caught after my round-3 fixes (both new on
its re-run, not in the original report):

- BAS account overlap not prevented: my BAS_RANGES_BY_CATEGORY uses the same
  class range for asset and accumulated (e.g. immaterial: both 1010–1099,
  building: both 1100–1199). Nothing stopped a user from picking the same
  account for both, which would silently net acquisition cost against
  accumulated depreciation in one bucket and corrupt INK2R 720x mappings.
  CreateAssetSchema now rejects bas_asset_account === bas_accumulated_account
  in a superRefine cross-field check; updateAsset enforces the same invariant
  by reading the existing asset and validating the merged result.

- declining-balance methods silently fell back to linear. The DB enum allowed
  declining_balance_30 / declining_balance_20, but the engine's
  computeAnnualDepreciation only implements linear math. A determined caller
  (MCP, curl, future UI) could create an asset labelled as räkenskapsenlig
  avskrivning and get linear charges — silently wrong numbers under a
  misleading method. Both CreateAssetSchema and UpdateAssetSchema now refine
  the depreciation_method enum to require 'linear'. The DB enum stays open
  for a future phase to add proper support. Stale comment in
  depreciation-engine.ts updated to reflect the new invariant.

False positives I'm explicitly not chasing further on this round:
- 3× repeated OWASP V8.2.1 cross-tenant — services already filter by
  company_id; bot can't see past the route handler. Round 3 already added
  service-layer tests and inline reasoning.
- V2.3 atomicity upgrade to high — bot now flags it harder *because* I
  documented it in round 3. The existing executeYearEndClosing has the same
  non-transactional sequential-write pattern; wrapping just this endpoint
  in an RPC while leaving the rest inconsistent is worse than the doc
  comment. Real atomicity is Phase 5+.
- Disposal VAT user-facing warning — no UI surfaces dispose yet; docstring
  in the service is sufficient until the UI ships.

Verification
- 119 tests pass
- Zero lint or typecheck errors on any touched file

* fix(bokslut): address compliance round 5 — disposal integrity + öavskr accounts

Round-5 bot feedback after my round-4 push (the sticky reports re-edited
themselves with two new genuine findings; bot count: 18 → 14 active).

P1 — accumulated_depreciation was client-supplied (OWASP V8.2.1, swedish
compliance review): the dispose endpoint accepted accumulated_depreciation
as a request-body number. A malicious or buggy caller could inflate it to
manipulate the book-value calculation and pocket a phantom gain. Now:

- DisposeAssetSchema no longer accepts accumulated_depreciation
- disposeAsset sums planned_depreciation from depreciation_schedules where
  journal_entry_id IS NOT NULL for the asset, server-side
- New regression test "server-derives accumulated_depreciation — caller
  cannot inflate gain" pins the server-derivation against the prior attack
- Limitation: manual avskrivningsverifikationer posted outside the engine
  aren't captured. Phase 5+ can swap this for a trial-balance scan on
  bas_accumulated_account if that gap matters.

P2 — överavskrivningar hardcoded 8853/2153 regardless of asset category
(swedish-asset-accounting): for buildings BAS uses 8852/2152 and for
immateriella tillgångar 8851/2151. Edge case for K2 SME (öavskr on
buildings is rare; on immateriella rarer still) but worth not lying about
the accounts. Now:

- New OVERAVSKRIVNING_ACCOUNTS table maps category → expense/accumulated
  pair (machinery_equipment, building, immaterial, group)
- proposeOveravskrivningar accepts optional category, defaults to
  machinery_equipment (the dominant K2 case — no behaviour change for
  existing callers)
- POST handler item schema accepts optional category
- Label + description strings now name the actual accounts used
- 3 new tests cover the building, immaterial, and default branches

False positives I'm still declining to chase (already covered in prior
commit messages):
- 3× repeated OWASP V8.2.1 cross-tenant — services scope by company_id;
  bot can't see past route handler
- V2.3 atomicity — existing executeYearEndClosing has the same pattern;
  wrapping just this endpoint is inconsistent; real fix is Phase 5+ RPC
- Disposal VAT user-facing warning — no UI surfaces dispose yet

Verification
- 123 tests pass (was 119, +3 for öavskr category branches and +1 for the
  server-derivation regression test, with one prior test rewritten to use
  the new server-supplied accumulated path)
- Zero lint or typecheck errors on any touched file

* fix(bokslut): pre-merge polish — building disposal accounts, SLR-2026 rate

Last polish round before merge. All three from the round-5 sticky
Swedish-accounting-review update:

- Building / markanläggning disposal posted gain/loss to 3973/7973. BAS
  2026 routes those to 3971/7971 (the SRU mapping points them at a
  different INK2R field, so the existing accounts misclassify). Extended
  the existing immaterial branch (3013/7813) into a three-way:
    immaterial            → 3013 / 7813
    building / land_imprv → 3971 / 7971
    other tangible        → 3973 / 7973
  Two new regression tests pin the building and land_improvement branches.

- DEFAULT_SCHABLONINTAKT_RATE was 0.03, based on SLR 2024-11-30 (1.96 %).
  For closings of inkomstår 2026 the rate is SLR 2025-11-30 (2.55 %) + 1 pe
  = 3.55 %. The wrong rate under-taxes the schablonintäkt, which feeds into
  bolagsskatt. Updated to 0.0355 and rewrote the doc comment to track both
  years so the next bump is obvious.

- Jämkning of input VAT for buildings / markanläggning disposed within the
  10-year jämkningsperiod (ML 9 kap 8–11 §§) is out of scope for this PR
  but should not be silently absent — added a KNOWN LIMITATION block to the
  disposeAsset docstring so any future UI surfacing disposal checks the
  10-year window and warns the user.

After this push the PR has 125 passing tests, all CI green, no merge
conflicts, and the only remaining bot complaints are repeat false
positives or Phase 5+ scope (RPC atomicity, full asset disposal UI,
K3 component depreciation).
