* fix(supplier-invoices): make the 'overdue' label two-way and stop it locking an invoice The daily cron flips unbooked payables past their due date to 'overdue' but nothing ever flipped them back, so aging alone pushed an invoice out of every workflow that gated on 'registered': it could not be edited (not even to extend the due date that made it overdue) and it could not be attested. Deletion was already unblocked in #1204; this closes the rest of #1206. - update_overdue_supplier_invoices() gains the inverse branch: a payable whose due date is no longer in the past returns to its resting status. Because the flip collapses 'registered' and 'approved', the un-flip needs a separate attest marker: new supplier_invoices.approved_at, backfilled from updated_at for rows currently sitting in 'approved'. - PUT /api/supplier-invoices/[id] accepts every unsettled status and recomputes the label from the due date it writes, in both directions, instead of leaving it up to a day stale. The update body carries metadata only (numbers, dates, reference, notes), never amounts or accounts, so a posted registration verifikat cannot be desynced by money. - Approve (web route, v1 API, MCP staging tool, staged commit executor) keys off approved_at instead of status === 'registered', so an aged invoice can still be attested. A still-late invoice keeps the 'overdue' label after attest: approving is not a reason to hide that the money is late. - One shared predicate in lib/supplier-invoices/lifecycle.ts for all five call sites, mirroring the SQL; new SI_EDIT_INVALID_STATUS replaces the raw Swedish string the edit gate used to return. Tests: 12 pg-real cases on the cron (5 new, covering both directions and the credit-note/fully-paid boundaries), plus route tests asserting the exact written payload for PUT and approve, and unit tests pinning the shared predicate against the SQL. npm test (11385), lint, check:guards clean. Closes #1206 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(migration): mark backfilled approved_at values as derived, not audit facts Compliance review on #1227 flagged that approved_at = updated_at could later be mistaken for an observed attestation moment (BFNAR 2013:2 kap 8 behandlingshistorik). The column comment and the migration now state plainly that pre-migration values are derived and that audit_log, written by the audit_supplier_invoices trigger, remains the record of what happened. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(supplier-invoices): guard the derived status writes with compare-and-swap Review findings on #1227. The status these paths write is derived from facts read a moment earlier, so an unconditional write could overwrite a concurrent cron flip, edit or approval with a label computed from what those changed. - PUT pins status, due_date and approved_at when (and only when) it derives a new status; zero matched rows is now a retryable 409 SI_EDIT_CONFLICT instead of a silently stale label. Metadata-only updates keep writing unconditionally: they never touch status, so they cannot clobber it. - The web approve route and the staged-commit executor gain the same pre-approval guard the v1 route already had (status in registered/overdue, approved_at IS NULL) plus a !data race check, so two concurrent approvals can no longer both stamp approved_at and both emit supplier_invoice.approved. - The v1 guard additionally pins due_date, since nextStatus is derived from it. - The list page no longer invents status/approved_at when the approve response is incomplete: it re-reads instead. An operator about to pay must not be shown a fabricated lifecycle state. - route.overdue.test.ts clears the module-level event bus like its sibling. Tests: new conflict cases for both paths (409 on PUT, refusal without an event emission on approve). npm test 11387 passed, lint 0 errors, check:guards clean, 12 pg-real cases green.

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.
