* feat(mcp): payroll e2e parity: staged salary-run booking + absence deletion

Close the last MCP-surface gaps for running payroll end-to-end via the
connector (the v1 REST API already had the full chain):

- gnubok_book_salary_run: stages a high-risk book operation; on approval
  the executor walks review -> approved -> paid -> booked via the new
  lib/salary/book-run.ts (extracted from the dashboard book route, which
  now calls the same core) and posts the immutable salary vouchers.
- gnubok_delete_absence: staged inverse of gnubok_register_absence,
  reusing deleteAbsenceRange with a dry-run day-count preview.
- Wire the missing payroll operation types into the Granskning label map
  (register_absence, update_payslip_line, employee ops, vacation_year_close
  had translations but fell back to humanized snake_case).
- Update stale 'booking happens in the web UI' prose in tool descriptions,
  the payroll-monthly skill, and the workflow hint; payload-size ceiling
  56K -> 57K per the documented bump protocol.

* fix(mcp): widen pending_operations op-type CHECK + roster typing for book_salary_run

The op-type audit (pg-real) caught the exact bug class it exists for:
book_salary_run and delete_absence were staged in code without the
constraint-expansion migration, so every real staging INSERT would have
failed with check_violation while dry_run previewed clean. Ships the
documented widen (NOT VALID) + validate migration pair. Also fixes the
strict-mode cast in book-run.ts that failed the production typecheck.

Verified locally against supabase/postgres 15.8.1.060 with all migrations
applied: op-type audit green, pg-real 692/693 (the one failure is the
pre-existing TZ-sensitive get_unlinked_1930_lines assertion, green under
TZ=UTC as in CI).

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.

  1. additionalProperties: false on every inputSchema. Guarded by strict-schemas.test.ts. Forces clear rejections on hallucinated fields instead of silent ignores.
  2. Descriptions ≤ 280 chars. Guarded by output-schema.test.ts. No Args: / Returns: / Examples: prose: those belong in JSON Schema. Use agent-native hints ("Use to…", "Call X first", "HIGH risk").
  3. Staged-operation envelope for write tools: outputSchema: STAGED_OPERATION_SCHEMA (server.ts). Fields: staged, risk_level, actor, message, preview, period_status?, next?. The staged: true boolean is the explicit completion signal; agents must not infer completion from prose. Do NOT introduce a parallel { success, shouldContinue, output } envelope.
  4. period_status threading: any tool that ties to a fiscal-period-bound date (categorize, mark paid, create voucher, correct/reverse entry, approve supplier invoice) passes dateForPeriodCheck to stagePendingOperation. Response then includes period_status: { period_id, status: open|locked|closed, lock_date } so widgets and agents disable writes without round-trips.
  5. Scope mapping: every new tool needs an entry in lib/auth/api-keys.ts TOOL_SCOPE_MAP. Missing entries default to deny.
  6. Tests for new write tools: add staging-gate coverage to __tests__/voucher-tools.test.ts (or a sibling) plus executor coverage to lib/pending-operations/__tests__/voucher-executors.test.ts if the tool stages a new operation_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).

Where things live

  • server.ts: the tools array + JSON-RPC dispatcher
  • tool-result.ts: withNext(), toToolError() response helpers
  • resources/: read-only Accounted:// URIs (active company, period, recent activity, capabilities, attention items, voucher gaps, chart of accounts, VAT treatments)
  • widgets/: inline HTML widgets (receipt-matcher, vat-review)
  • prompts/: slash-command-style prompts
  • skills/: domain-knowledge skill bodies served via gnubok_load_skill
  • __tests__/: strictness guards + per-tool coverage
