A reversed (storno-corrected) journal entry must be summed together with
its storno + correction, exactly as the trial balance and balance sheet
already do (.in('status', ['posted','reversed'])). The reconciliation
paths used posted-only and manufactured phantom differences.
- bank-reconciliation getReconciliationStatus: gl_1930_balance now counts
posted+reversed (so it equals the balansräkning for the account). Dropped
the correction_adjustment subtraction and the reversed-linked-tx drop — a
corrected/amount-corrected bank receipt now reconciles. The prior model
broke once correctEntry began re-pointing the bank transaction to the live
correction (the two changes were mutually inconsistent and produced a
difference equal to the corrected amount).
- supplier-reconciliation (2440) and ar-reconciliation (1510/1513): same
posted -> posted+reversed fix. Removes the false "Ej avstämd" gap a fully
paid, fully corrected company shows — the books net to 0 over posted+reversed
while a posted-only query double-counted the payment legs.
Also in this change:
- MCP gnubok_get_reconciliation_status: add account_number param (was hardcoded
to 1930; the lib already supported per-account reconciliation).
- counterparty-templates normalizeCounterpartyName: strip trailing month /
personal-initials tokens so "ngrok JW" / "Ngrok Mars" learn as one merchant.
- pending-operation reject 409 (route + MCP tool): clarify a resolved op was
approved explicitly (no auto-commit path exists) instead of a bare
"already committed".
- create_voucher: normalize description with String().trim() for consistency
with line_description.
- migration 20260625120000: backfill stripped diacritics on ~830 companies'
seeded chart-of-accounts names (Foretagskonto -> Företagskonto, etc.); the
seed function was fixed for new companies in 20260516130000 but never
backfilled. UPDATE-only and idempotent. Already applied to production.
Tests: 899 passing across the touched suites; lint + typecheck clean.

Accounted MCP server
JSON-RPC 2.0 server exposing the Accounted bookkeeping engine to MCP clients (Claude Desktop, Claude Code, etc.). Endpoint: /api/extensions/ext/mcp-server/mcp. OAuth and stdio bridge live alongside the API surface — see app/api/mcp-oauth/ and packages/gnubok-mcp/.
Tool authoring contract
Enforced by tests in __tests__/ — these are not style preferences, they're guard rails.
additionalProperties: falseon everyinputSchema. Guarded bystrict-schemas.test.ts. Forces clear rejections on hallucinated fields instead of silent ignores.- Descriptions ≤ 280 chars. Guarded by
output-schema.test.ts. NoArgs:/Returns:/Examples:prose — those belong in JSON Schema. Use agent-native hints ("Use to…", "Call X first", "HIGH risk"). - Staged-operation envelope for write tools —
outputSchema: STAGED_OPERATION_SCHEMA(server.ts). Fields:staged, risk_level, actor, message, preview, period_status?, next?. Thestaged: trueboolean is the explicit completion signal; agents must not infer completion from prose. Do NOT introduce a parallel{ success, shouldContinue, output }envelope. period_statusthreading — any tool that ties to a fiscal-period-bound date (categorize, mark paid, create voucher, correct/reverse entry, approve supplier invoice) passesdateForPeriodChecktostagePendingOperation. Response then includesperiod_status: { period_id, status: open|locked|closed, lock_date }so widgets and agents disable writes without round-trips.- Scope mapping — every new tool needs an entry in
lib/auth/api-keys.tsTOOL_SCOPE_MAP. Missing entries default to deny. - Tests for new write tools — add staging-gate coverage to
__tests__/voucher-tools.test.ts(or a sibling) plus executor coverage tolib/pending-operations/__tests__/voucher-executors.test.tsif the tool stages a newoperation_type.
Determinism / cache stability
Tool definitions (name, description, inputSchema, outputSchema, annotations) are declared as static object literals at module load — no timestamps, no UUIDs, no Date/Math.random in the definition layer. This makes the tools/list JSON payload byte-stable across requests, which lets agent-side prompt caches stay warm. Do not introduce per-request non-determinism into the definitions block. Anything time-bound or random belongs inside execute().
For internal Anthropic API usage (today only extensions/general/invoice-inbox/lib/extract-invoice-fields.ts): annotate stable prefixes with cache_control: { type: 'ephemeral' } and log usage.cache_read_input_tokens for hit-ratio observability. The 1h TTL from the agent-native API plan (item 10) requires the direct Anthropic API; Accounted's Bedrock path defaults to a shorter TTL.
Payload-size watchdog
payload-size.bench.test.ts enforces a tools/list JSON payload ceiling (currently 36,000 tokens — bumped from 32,000 when top-level Tool.title landed on all tools for Claude Connectors Directory readiness). If the test fires, the right answer is rarely "raise the ceiling" — instead, trim descriptions or leverage gnubok_search_tools (already deployed; tool definitions can defer to it for discovery rather than enumerating in tools/list).
