* fix(vat): keep the momsrapport intact after a manual nollställning (#984) The momsrapport already excludes settlement verifikat tagged with source_type 'vat_settlement' (#983), but settlements booked any other way still zeroed every ruta the moment they were posted: manual momsomföringar booked before the tagged flow existed (the report in issue #984), SIE-imported settlements, and storno reversals of a settlement, which inverted the sign instead and silently doubled the rutor after an annullera. Exclude settlement entries by SHAPE as well: an entry with at least one line on a declaration account (ACCOUNT_RUTA) and at least one on a settlement net account (2650/1650) is bookkeeping about the declaration, not VAT-bearing activity, in both the web projection (fetchVatAccountTotals) and the MCP twin (computeVatReport). Opening-balance entries are exempt: carried-in 26xx balances are unsettled VAT that belongs in the next declaration. Shape-detected POSTED settlements now also gate the "Skapa verifikat" button through existing_entries, since the proposal re-clears the full period and booking it on top of a manual settlement would corrupt the 26xx balances. Stornos never gate, so annullera still re-enables booking. Fixes #984 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(mcp): stable id order for the paginated VAT-report line fetch (CodeRabbit) fetchAllRows pages with .range(); without a unique .order() rows can shift across page boundaries once a period exceeds 1000 lines, skipping or double-counting journal lines in the rutor. Same discipline as the web projection (fetch-all.ts). Pre-existing, but the query was already being touched for #984. Also documents the shape-rule triage from the compliance-bot review in DECISIONS.md: compound business-VAT-plus-2650 verifikat stay a known accepted residual (a direction guard would break the storno exclusion), and the opening-balance concern is false for app flows (SIE import and set_opening_balances both tag source_type 'opening_balance').

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).
