* fix(skattekonto): route AGI draw back to 2731 to match salary module (#1870) Migration 20260519160000 moved the skattekonto AGI seed to 2730 while the salary module kept crediting 2731, splitting the employer-contribution liability across two accounts that never net at account level (both carry SRU 7231, so only huvudbok reconciliation exposes the drift). Revert the system seed to 2731: BAS 2026 defines 2731 as the reported-but-unpaid arbetsgivaravgift liability (the accrual account is 2940), and the salary ore-residual logic is built around 2731. Historical 2730 debits since 2026-05-19 are left for per-company reclass verifikat; the migration touches the system seed only. Fixes #1870 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(skattekonto): bump migration version to avoid collision with 20260825120000_create_company_for_user Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(payroll): align remaining 2730 guidance surfaces on 2731 (#1870) Skeptic regression finding: companies booking salary manually were taught 7510/2730 by in-product guidance, so the seed revert alone would re-create the #1870 split mirrored for them. Align every guidance surface on 2731: - packs/loneutbetalning.yaml legal_note - MCP payroll-monthly skill (booking recipe and rate notes) - swedish-payroll SKILL.md + references/bas-7xxx.md (2731 convention, 2730 group-account alternative, never mixed; accrual is 2940) + regenerated agent atom seed (skills:generate -> 20260825180001) - public/docs/systemdokumentation-mall.md Also addresses the compliance review finding that the swedish-payroll skill contradicted the migration.

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. Add ?tool_namespace=accounted for the Accounted tool names. Requests without it retain the legacy Gnubok namespace. OAuth and stdio bridges live alongside the API surface: see app/api/mcp-oauth/, packages/accounted-mcp/, and the compatibility package in 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. If the test fires, the right answer is rarely "raise the ceiling". Instead, trim descriptions or set specialized wide tools to catalogVisibility: 'search'. Those tools remain discoverable with full schemas through gnubok_search_tools and callable through tools/call without bloating the default catalog.
