ccdfed5fea feat: voucher linking, recovery ops, and salary overrides (#591)
* feat: voucher linking, recovery ops, and salary overrides

Adds reversible/correction-style write paths that customers and agents have
been asking for, plus per-run salary employee overrides.

Invoice → voucher linking
- POST /api/invoices/[id]/link-to-voucher and
  GET /api/invoices/[id]/voucher-candidates
- lib/invoices/voucher-matching.ts with full + pg test coverage
- LinkVoucherPicker UI in PaymentBookingDialog
- pending_operations.operation_type expanded with link_invoice_voucher
  (medium risk) and a (journal_entry_id, invoice_id) unique guard
- MCP: gnubok_find_voucher_candidates_for_invoice and
  gnubok_link_invoice_to_voucher tools

SIE undo
- POST /api/import/sie/[id]/undo + undo_sie_import RPC
- sie_imports.status gains 'undone'
- ImportResultStep surfaces the action; structured error SIE_UNDO_FAILED

Edit-recreate journal entries
- POST /api/bookkeeping/journal-entries/[id]/edit-recreate
- Bookkeeping detail page wires it into the existing edit flow

Delete-last-voucher clears IB link
- Trigger + pg test ensure deleting the last voucher of a period nulls the
  opening_balance_journal_entry_id link so a re-import lands cleanly

Salary employee overrides
- salary_run_employees gains per-run override fields + migration
- lib/salary/effective-values.ts centralises resolved values; all payslip,
  payment, AGI, KU, and booking routes read through it
- SalaryOverridePanel on the employee detail page

Account classifier
- lib/bookkeeping/account-classifier.ts + tests; AddAccountDialog uses it
- backfill-import-accounts script updated

Misc
- toast: minor styling tweak
- AGI generate-declaration: respect effective values
- structured-errors: new LINK_INVOICE_VOUCHER namespace

* feat: add link_invoice_voucher operation type to pending_operations

* feat: refactor salary run calculations and update error handling for SIE imports

* fix: PR review feedback on voucher linking and SIE recovery

pg-real (blocking):
- tests/pg/delete-last-voucher-ib: drop posted_at = now() from the seed
  UPDATE — journal_entries has no posted_at column.
- lib/invoices/__tests__/voucher-matching.pg: seed the posted voucher
  before closing the fiscal period so enforce_period_lock doesn't block
  the INSERT during setup.

voucher-matching error codes and rollback:
- Add LINK_VOUCHER_DB_ERROR (HTTP 500) and return it on real invoice
  UPDATE / payment INSERT failures. Previously these returned
  LINK_VOUCHER_VOUCHER_NOT_FOUND (404) which the pending-op dispatcher
  auto-rejects on transient DB errors.
- Log rollback failures explicitly so an invoice left in a half-linked
  state (advanced status, no payment row) surfaces for manual
  reconciliation instead of disappearing silently.

resyncNextPeriodOpeningBalance ordering:
- Create the new IB first, relink the period FK, then storno the old IB.
  Previously the storno ran first; if createJournalEntry failed the next
  period was left with a reversed IB and nothing to replace it, and
  executeSIEImport swallows the error as a non-fatal warning.

replace_period_opening_balance_link:
- Tighten role check to owner/admin (was owner/admin/member). Matches
  delete_last_voucher and undo_sie_import.

Data minimisation:
- /api/invoices/[id]/voucher-candidates and the matching MCP tools now
  project only the invoice and customer fields the matcher reads, instead
  of returning the full customer row.

Schema bounds:
- SalaryEmployeeOverrideSchema caps each numeric override at 10 MSEK to
  catch typos before they reach the ledger or AGI.

* fix(tests): supply user_id when seeding voucher_sequences

voucher_sequences.user_id is NOT NULL (per the multi-tenant refactor in
20260330130000). The previous test seed only set company_id /
fiscal_period_id / voucher_series, which made the seed fail with a
constraint violation on the latest pg-real run. Pass the same userId
used elsewhere in the seed helper.

* fix(tests): scope delete-last-voucher RPC assertions inside the tx

withUserContext always ROLLBACKs, so any DELETE the RPC performs is
discarded when the callback returns. The previous test then queried
journal_entries via a fresh getPool() connection that only saw the
pre-RPC committed seed state — hence "expected '1' to be '0'".

Move every post-RPC assertion (entry count, period FK clear,
opening_balances_set flip, audit log entry, sie_imports clear) inside
the same withUserContext callback so they observe the uncommitted state
before ROLLBACK fires.

Also fix the sie_imports INSERT: the column is `filename`, not
`file_name`, and `sie_type` is NOT NULL.

* fix(tests): assert against the IB-marker audit row directly

DELETE on journal_entries fires two audit_log writes: the generic
write_audit_log() trigger row ("Deleted journal_entries record") and the
delete_last_voucher RPC's explicit "(was period IB)" entry. Both land
at the same statement_timestamp(), so ORDER BY created_at DESC LIMIT 1
returned the trigger row non-deterministically in CI.

Switch to a presence check with a LIKE filter on the IB marker so the
test verifies what it actually cares about — that the RPC's IB-aware
audit row exists.

* fix(db): set company_id on delete_last_voucher audit_log rows

20260528120000_delete_last_voucher_clears_ib_link.sql inserts directly
into audit_log without setting company_id. audit_log's SELECT policy
filters company_id IN user_company_ids(), so those rows landed with
company_id=NULL and were invisible to every reader — only the generic
write_audit_log() trigger row remained visible. That broke BFL audit-
trail intent: the "(was period IB)" provenance row was never readable.

Republish delete_last_voucher with p_company_id populated on both
audit_log INSERTs (draft path and posted path). Behavior is otherwise
unchanged; the pg-real test for the IB-clear flow now sees the
RPC-written marker row as expected.

gnubok MCP server

JSON-RPC 2.0 server exposing the gnubok 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; gnubok'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).

Where things live

  • server.ts — the tools array + JSON-RPC dispatcher
  • tool-result.tswithNext(), toToolError() response helpers
  • resources/ — read-only gnubok:// 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
