* feat(auth): SoD acknowledge on stage+approve keys + agent:write scope for memory tools Segregation of duties on API keys is now warn + explicit acknowledgement (not block): minting a key with any staging write scope AND pending_operations:approve returns 409 API_KEY_SOD_CONFLICT unless the caller re-POSTs with acknowledge_sod: true. The acknowledgement is recorded (sod_acknowledged_at / sod_acknowledged_by) for an auditable risk acceptance (ISO 27001:2022 A.5.3 / BFNAR 2013:2). The create UI surfaces an inline warning and an explicit confirm dialog before submitting the ack — the default "all scopes ticked" create routes through that path. Also introduces the agent:write scope and maps the previously-UNMAPPED memory tools gnubok_remember_fact / gnubok_forget_fact to it. Because unmapped tools were callable by any key, the migration grandfathers agent:write onto every existing non-revoked key with an explicit scope list so nothing regresses; new keys must opt in. agent:write is deliberately excluded from the default grants and is NOT a staging scope (no SoD conflict with approve).

Adds a paired-NULL CHECK constraint + pg-real coverage for both partial-write directions. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(auth)+feat(auth): compliance-review round — self-attestation documented, ack logged, SoD boundary assumption captured - Migration header now states explicitly that the SoD acknowledgement is a SELF-attestation by deliberate design (enskild firma has no second person; the claude.ai approval flow needs stage+approve on one credential) — the control objective is informed consent + audit record, not dual control. - The acknowledge_sod=true path now emits a structured log.warn (api_key.sod_acknowledged with key id/prefix, conflicting scope, scopes, acknowledger, company) so the acceptance lands in the logging pipeline in addition to the sod_acknowledged_* columns (ASVS V16.1.1). - STAGING_SCOPES carries the documented system control (BFNAR 2013:2 systemdokumentation) for why agent:write is not a staging scope: memory tools write advisory agent context and cannot stage räkenskapsinformation. Dismissed as by-design/verified: hard-block and second-approver remediations (user decision: warn + acknowledge); scope-update gap (the [id] route only supports DELETE — scopes are immutable post-creation); session-auth concern (withRouteContext is cookie+MFA only; API-key auth exists only on /api/v1 and MCP).

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 25,000 tokens). 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).
