c2f055b903 fix(bank): 90-day lookback is the default: long PSD2 requests make some banks kill the session (#1964)
E2E #11: the account picker's fiscal-year default sent a 365-day request
for a 405-day-old fiscal year; Swedbank answered by TERMINATING the
session: zero transactions, connection expired, no error surfaced
(initial_sync_requested_from 2025-08-26, returned min/max null). 90
days worked.

- Default lookback mode is now 'fast' (90 days), labeled rekommenderas
  on a first connect; the fiscal-year option stays but carries an inline
  'vissa banker avbryter kopplingen' note when its span exceeds 90 days,
  and the long-range helper names the real failure mode + the SIE/CSV
  path for older history.
- SIE drop card: stage + arm in ONE click (three clicks was one too
  many): after the verdict, the single button reads 'Bokför:
  oåterkalleligt (BFL 5 kap 5 §)' and the deliberate click commits with
  confirmed=true.
- Skill: never re-ask an answered question; when a connect card
  rendered, do not paste the URL as text too.

53c4d0d194 feat(mcp): approve the SIE import in the drop card + post-import efterkontroll in the skill (#1963)
E2E #10 (the first fully successful drop-card run) left the staged
import stranded until the user prodded the agent, and the agent then
improvised an excellent post-import audit (skattekonto reconciliation,
missing 1630, over-stated payroll liabilities). Codify both:

1. The drop card now carries the approval: after staging, the button
   becomes 'Godkänn bokföringen' with a two-click BFL confirmation
   (confirmed=true armed on the deliberate second click, exactly the
   pending-operations widget pattern), then 'Bokfört' + a ui/updateContext
   pointing the agent at trial balance and voucher-gap follow-ups.

2. Skill: when the user writes after a card was shown, the FIRST call is
   list_pending_operations (an empty ledger does not mean the file never
   arrived); new Step 4b 'efterkontroll' codifies the audit pass
   (trial balance vs SIE, skattekonto vs 1630 with 8423/8314/6992 for
   ränta/avgifter, auto-created bank account names, underlag coverage,
   voucher gaps); memory-first extended with memory-back (save orgnr,
   bank, fiscal year, moms period after creation so the next
   conversation needs zero questions).

d8244ecaff feat(mcp): connect_migration: one-click card into the previous-system wizard (#1960)
* feat(mcp): gnubok_connect_migration: one-click connect card into the previous-system wizard

'Jag hade Fortnox' now gets the same feel as Skatteverket: the tool
returns the migration-wizard link for the named provider and renders
the connect-card widget (new migration branch: 'Hämta från Fortnox',
button opens the wizard that logs into the old system and fetches all
fiscal years plus invoices, customers, suppliers and documents). For
visma/bokio (no API export) the instructions order the SIE drop card
first and this card as the complement. Scope companies:read; skill
step 3 points at the tool instead of raw wizard links; ceiling 62.4K
to 63K documented.

* fix(mcp): 5-minute freshness hint on tools/list, widgets and prompts: the catalog changes with every deploy

The stateless-client CacheableResult hint on tools/list, resources/read
(widget HTML) and prompts/list was 1 hour. Claude.ai honors it, so for
up to an hour after a deploy the connector served a pre-deploy catalog:
a freshly shipped tool flapped in and out of the tool list depending on
which fetch hit the client cache, and two E2E runs dead-ended on
'tool does not exist' for a tool that was live server-side. These
payloads are static only within one deploy; 5 minutes bounds the stale
window.

0f7625535b feat(mcp): drag-and-drop SIE import card: exact bytes via tools/call, no model in the byte path (#1957)
E2E #6: the flow ordered SIE-first correctly, but the agent never
discovered gnubok_create_sie_upload, ran a local preflight, and sent the
user to the web wizard again; it also rendered a duplicate generic bank
card before the Swedbank-specific one.

1. New sie-drop widget (ui://sie-drop/app.html), rendered
   definition-level by gnubok_create_sie_upload: the user drags the
   .se/.sie file onto the card, the widget reads the EXACT bytes
   (FileReader), computes sha256 (WebCrypto), calls
   gnubok_sie_preflight via tools/call with file_content_base64 +
   sha256, shows the verdict, and on Importera stages
   gnubok_import_sie with the preflight's mappings. No network from
   the iframe, no model reproduction: byte path goes through the host
   bridge only, narrated into chat via ui/updateContext.

2. The inline size cap now applies only WITHOUT sha256: a hash-verified
   payload is byte-exact by proof, so the widget's 100 KB+ base64
   passes while unhashed model-retyped content stays refused.

3. Discovery + ordering fixes: create_sie_upload/preflight/import
   descriptions name the card path explicitly; create_company's
   history_note points at the card; connect_bank description says pass
   bank on the FIRST call when the user has named it (the duplicate
   generic card came from a bare call followed by the nudged retry).

151fb1384c feat(mcp): connect card widget: one-click open-in-browser button for bank and Skatteverket links (#1939)
The gnubok_connect_bank and gnubok_connect_skatteverket tools now carry
definition-level _meta.ui.resourceUri pointing at a new connect-card MCP
Apps widget. On claude.ai/Claude Desktop the tool result renders as a card
with an "Öppna i webbläsaren" button that sends the host a ui/open-link
request from the click handler (the sanctioned new-tab mechanism; custom
connectors always get Claude's confirmation modal, so the destination URL
is shown in the card). Clients that do not render MCP Apps (Claude Code)
keep the connect_url in the structured result as before.

Jakob WennbergandClaude Fable 5 4501f118c2 feat(mcp): approval-queue MCP Apps widget for staged operations (#1278)
* feat(mcp): approval-queue MCP Apps widget for staged operations

gnubok_list_pending_operations(render_ui=true) now renders an interactive
approval queue (claude.ai / Claude Desktop) where the user approves or
rejects each staged operation with a click. High-risk operations arm the
approve button and the second click sends confirmed=true, so the BFL
5 kap 5 acknowledgment is a first-party human action instead of the
agent asserting confirmed=true on the user's behalf (the audit weakness
flagged in dev_docs/erpclaw_analysis.md).

- New widget ui://pending-operations/app.html following the established
  self-contained postMessage/JSON-RPC pattern (no fetch, theme-aware,
  Swedish labels, expandable preview_data per row).
- Result-level _meta.ui hint gated on render_ui=true, mirroring the VAT
  report wiring; the tool stays data-only by default.
- Widget tool references project per namespace (accounted_* clients see
  accounted_ names inside the HTML).
- tools/list payload ceiling 58K -> 58.5K per the in-test convention:
  prose trimmed to the floor first, remainder is wire contract.

* fix(mcp): time out the widget RPC bridge so a silent host cannot strand a row

Review follow-up: sendRequest never settled if the host dropped a
response, leaving op._working=true forever with the approve/reject
buttons gone. A 30s timeout rejects the promise; the existing catch
paths restore the row with an error message so the user can retry.

Jakob WennbergandClaude Fable 5 9b3e344796 fix(notifications,mcp): carry the record's currency in amount strings (#1179)
Fixes #1171. Three currency-blind format sites:

- Invoice due/overdue push notifications rendered every total as kr;
  the scheduler query did not even select currency. Builders now take
  the invoice currency ("kr" only for SEK, ISO code otherwise).
- The receipt-matcher MCP widget hardcoded ' kr' although the tool
  handler passes each transaction's currency through.
- The duplicate-booking warning in gnubok_categorize_transaction
  interpolated "N kr" for a transaction whose currency was already
  selected; the string reaches the agent, so a mislabeled currency can
  mislead the model, not just the user.

Jakob WennbergandClaude Sonnet 5 ec27228a8e style: remove em/en dashes repo-wide, add CLAUDE.md rule against them (#890)
Em dashes (—) and en dashes (–) had spread across comments, docs, tests,
and a few UI strings, reading as AI-generated boilerplate rather than
house style. Replaced each with punctuation matching its context: colon
for explanatory clauses, comma for asides, plain hyphen for numeric/legal
ranges (e.g. "21-23§"), "to"/"till" for date ranges, parentheses for
paired-dash asides. messages/en.json and messages/sv.json were fixed by
hand together to keep sv/en in sync.

Left untouched where the dash is the functional subject rather than
decorative punctuation: date-range-parser.ts's separator regex,
charset-repair.ts's CP1252 byte-mapping table (and its test), the SIE
encoding mojibake docs, generic-csv.ts's minus-sign normalizer, the
agent system-prompt files that already instruct against em dashes, and
a golden iXBRL test fixture compared byte-for-byte.

Also fixes two bugs surfaced along the way: an off-by-one in
ApiKeysPanel's scope-label split (a leftover from an earlier partial
pass), and a charset-repair test that had lost the literal en-dash it
exists to verify.

Regenerated the agent atom seed migration (skills:generate) since 27
SKILL.md files changed. Added a CLAUDE.md rule against em/en dashes,
with an explicit carve-out for the functional-dash cases above.

Jakob WennbergandClaude Opus 4.8 c74b19df1b Accounted rebrand + swarm-skill cleanup + bank-reconciliation fixes (#643)
* feat(reconciliation): close the bank-feed loop on voucher links and re-tag mis-typed opening balances

Two related fixes to bank reconciliation correctness:

1. Auto-reconcile on voucher link. Linking an invoice or supplier invoice to
   an existing voucher previously advanced only the invoice — the bank
   transaction that paid it kept sitting in the Transactions inbox with a null
   journal_entry_id. linkInvoiceToVoucher / linkSupplierInvoiceToVoucher now
   call autoReconcileTransactionForLinkedVoucher (lib/reconciliation), which
   links the bank transaction to the same verifikat when exactly one unbooked
   line matches it. Best-effort and post-commit: a failure here never fails the
   link. The result surfaces reconciledTransactionId; the inbox row leaves the
   list and the UI shows link_success_tx_reconciled.

2. Re-tag mis-typed opening balances. getReconciliationStatus and the GL-line
   matching RPCs identify a cash account's ingående balans solely by
   journal_entries.source_type='opening_balance'. Companies migrated from other
   systems often booked the bank IB as an ordinary voucher (source_type
   'import' or 'manual'), so it was never excluded and surfaced as a phantom
   reconciliation difference equal to the opening balance. Adds:
   - migration mark_entry_as_opening_balance: a GUC-gated carve-out in the
     immutability trigger plus a SECURITY DEFINER RPC that validates the entry
     (balance-sheet lines only, dated on a fiscal-period boundary), flips the
     source_type, and writes an audit row — no blanket data sweep.
   - POST /api/reconciliation/bank/mark-opening-balance + MarkOpeningBalanceSchema.
   - BankReconciliationView action to trigger it from the IB diff.

The gnubok_create_voucher executor now accepts a typed is_opening_balance flag
and derives source_type='opening_balance' only after validating class 1/2 lines
on the period start, so new IBs land correctly typed.

Covered by lib/reconciliation auto-reconcile tests, voucher-executors tests,
and a mark-entry-as-opening-balance pg-real test.

* chore: rebrand gnubok → Accounted and prune swarm agent skills

Product rebrand and skills housekeeping. No runtime behaviour change.

Rebrand: replace user-visible "gnubok" with "Accounted" across docs, READMEs,
in-code comments, doc-site content, MCP skill/resource prose, and the
gnubok-mcp package description. The MCP resource URI scheme is moved gnubok://
→ Accounted:// consistently across resource registrations, the event-type
comment, and the resource/skill tests. Deliberately preserved as stable
identifiers (NOT rebranded): the gnubok-company-id cookie, gnubok_sk_ / gnubok_inv_
token prefixes, the gnubok-mcp npm bridge name, and the AGI <gem:Programnamn>
value (kept 'gnubok' per its source comment — it is the software identifier sent
to Skatteverket and must not churn across visual rebrands).

Skills: remove the 27 swarm-* agent SKILL.md atoms (no longer used; already
absent from the agent_atom_registry in prod), refresh the remaining skill docs,
add the .claude/rules/ path-scoped rule set, and regenerate the
seed_agent_atom_bodies migration + .skill-body-manifest.json via
`npm run skills:generate` so the DB-backed skill bodies match the trimmed set.

Jakob WennbergandClaude Opus 4.7 5c52f24a49 feat(mcp): agent-native improvements — progressive discovery, widgets, skills, telemetry (#393)
* feat(mcp): agent-native improvements — progressive discovery, widgets, skills, telemetry

Four coordinated streams of MCP server improvements that move gnubok toward
agent-first design, grounded in Anthropic's Nov 2025 "Code execution with MCP"
article and the May 2026 MCP conference talk.

Context budget — minimize tools/list payload
- New gnubok_search_tools: progressive discovery with name|summary|full detail
  levels and scope filtering. Agents pull only the schemas they need.
- Trimmed all 50 tool descriptions from multi-paragraph blocks (avg ~500-1000
  chars) to one-sentence summaries (avg ~120 chars). Args/Returns/Examples
  blocks dropped — they duplicated inputSchema.
- outputSchema declared on every tool; structuredContent emitted on every
  successful tools/call (was previously only widget-tagged tools).
- protocolVersion bumped to 2025-06-18 (negotiates back to 2024-11-05).
- Workflow examples consolidated into initialize.instructions.
- Net effect: tools/list payload ~43 KB / ~10.8K tokens for 51+ tools, with
  headroom guard at 20K tokens.

MCP applications — server-shipped UI widgets
- New widgets/ directory with typed UiWidget contract; receipt-matcher moved
  out of widget-html.ts (which was deleted) into widgets/receipt-matcher.ts.
- New gnubok_vat_review_widget tool + interactive momsdeklaration widget
  (all 8 rutor with summary card, theme-aware light/dark, copy buttons).
- resources/list and resources/read iterate uiWidgets dynamically — adding
  the next widget is a single file drop.

Skills over MCP — domain-knowledge primitive
- 5 user-facing SKILL.md-style workflow guides authored from existing
  .claude/skills/swedish-* development skills:
  • month-end-close — book → reconcile → VAT (monthly filers) → lock
  • quarterly-vat-review — ruta-by-ruta map, deadlines, common errors
  • year-end-close — bokslut, bokslutstransaktioner, lock → year-end
    → opening balances → close (irreversible)
  • invoicing-rules — ML 17 kap. 24 §, customer types, ROT/RUT, Peppol
  • payroll-monthly — salary run → calculate → review → AGI XML
- gnubok_list_skills (with optional tag filter) + gnubok_load_skill(slug).
  Both unscoped — available to any authenticated key.
- Each skill also exposed as MCP resource at gnubok://skill/<slug>
  (text/markdown) for forward compatibility with a future native
  skills/list primitive.

Tool-call telemetry — measure before optimizing further
- Three new CoreEvent types (mcp.tool_called, mcp.tools_list_called,
  mcp.resource_read), all persisted to event_log (30-day TTL, RLS-scoped).
- Fire-and-forget emission from the dispatcher — never blocks JSON-RPC
  response, double-guarded against handler failures.
- tools/call instrumented at all four exit points (success, execution
  error, scope denied, unknown tool). Latency measured tightly around
  tool.execute() — excludes dispatcher overhead.
- tools/list logs returned tool count (informs progressive-discovery
  adoption); resources/read logs URI + kind discriminator (widget /
  skill / data / unknown).
- No PII or secret material in payloads — only metadata.

Out of scope (explicitly deferred):
- Code-mode SDK (no production code-mode hosts to consume it yet).
- Elicitations (require streamable HTTP transport — bigger architectural lift).
- DB lockdown / RPC funnel (foundational; should follow once telemetry tells
  us where writes actually flow).
- CRUD → intent endpoints (frontend coupling — multi-PR effort).

Tests: +37 new unit tests across search-tools, output-schema, payload-size,
vat-review-widget, skills, telemetry. Existing receipt-matcher test updated
for the new structuredContent contract. 2,615 unit tests passing.
Production build green. No new lint warnings or errors in changed files.

* fix(mcp): address PR #393 review findings

Greptile (P1 + P2) and the Swedish accounting compliance bot flagged 9 issues
across security, data correctness, and skill content. All addressed:

Security (P1)
- gnubok_search_tools: scope filter now fails closed when __keyScopes is
  absent. The earlier permissive default leaked the full tool inventory if
  the dispatcher's hard-coded name check ever silently broke. Marker presence
  is part of the contract — explicitly empty array also hides scoped tools.
  Two new test cases pin the fail-closed behaviour.

Compliance — VAT (data correctness)
- get_vat_report now aggregates 2614/2624/2634 (reverse-charge output VAT)
  and exposes them as ruta30/ruta31/ruta32 per SKV 4700. ruta48 also picks
  up 2647 (missing before). ruta49 formula corrected to
  (10+11+12+30+31+32) − 48. The widget renders the new rutor between the
  Utgående and Ingående sections.
- Widget ruta 05 sub-label updated from "3001+3002+3003" to "all momspliktig
  försäljning oavsett skattesats" — ruta 05 covers all domestic taxable
  supplies, not just direct-rate sales.
- Refactored: extracted computeVatReport() helper used by both
  gnubok_get_vat_report and gnubok_vat_review_widget. Removes the
  rename-fragile tools.find() lookup at runtime.

Compliance — payroll
- payroll-monthly skill: replaced "born 1958 or earlier = 10.21%" (the 2024
  formulation) with the statutory rule "age 66+ on 1 January of the income
  year (67+ from income year 2026)". Removed the unsourced "age 16–18:
  11.78%" row in favour of a current växa-stöd description with explicit
  Prop. 2025/26:34 reference and a "verify against current Skatteverket
  tables" caveat.

Compliance — skills text
- invoicing-rules: added explicit footnote on the 1 April 2026 livsmedel
  rate change. Restaurang/servering stays at 12 %; livsmedel sold in other
  forms drops to 6 %. Per Prop. 2025/26:55.
- year-end-close: clarified periodiseringsfond cap as "25 % of överskott
  before this year's avsättning" (IL 30 kap.), removing the ambiguous
  "skattemässigt resultat" phrasing that could be misread as a circular
  after-fond computation.

Schema correctness
- STAGED_OPERATION_SCHEMA.required gains "staged" — every path through
  stagePendingOperation returns the field, so the schema now matches the
  contract that MCP clients validate against.

Tests: 2,617 passing (+2 for the search-tools fail-closed cases).
Production build green.

* fix(mcp): address PR #393 round-2 compliance review

Round 2 of the swedish-compliance bot ran after the previous fix-push and
flagged four substantive items + a recommendation. All addressed:

VAT computation (data correctness)
- ruta05 expanded beyond 3001/3002/3003 to cover the common BAS taxable-
  revenue accounts (3001-3008, 3041-3048, 3051-3058, 3071-3078). Companies
  that book to 30xx alternates were previously under-reporting taxable
  turnover; now all standard BAS taxable-revenue numbering contributes.
- One-sided reverse-charge warning: when output VAT is booked on
  2614/2624/2634 (rutor 30/31/32 > 0) but the matching calculated input
  VAT (2645) is zero, computeVatReport now returns a Swedish-language
  warning string. ruta49 is inflated in this case — the warning surfaces
  the most common reverse-charge error per the swedish-vat skill. The
  widget renders warnings in a terracotta panel above the summary card.
- computeVatReport exported and a focused unit test added — exercises 2647
  inclusion in ruta48, reverse-charge balanced/unbalanced cases, and the
  expanded ruta05 mapping. Fills the gap that prior tools/call integration
  tests couldn't reach.

Skill content
- payroll-monthly Step 6: BAS journal-entry example no longer hard-codes
  31.42 % on the 7510/2730 lines. The avgift line is now described as
  "avgift_base × applicable_rate per employee" with explicit aggregation
  semantics for runs that mix full-rate and reduced-rate employees.
  Aligns with the Step-4 reduced-rate caveats already in place.
- invoicing-rules ROT/RUT block: replaced the bare "30 % / max 50 000 SEK"
  text with the full year-by-year picture — RUT 50 % / 75 000 max, ROT
  baseline 30 % / 50 000 max, 2024 H2 doubled ceiling, 2025 May–Dec
  enhanced 50 % rate. Defaults to "verify against current Skatteverket
  table" rather than a single hard-coded rate.

False positives in the round-2 review (no fix needed; documented for the
record):
- "Old vat_report path still computes ruta48 without 2647" — the old path
  was replaced by computeVatReport in the previous push; the bot was
  reading the diff hunk and conflating it with current behaviour.
- "Widget prose says ruta49 = (10+11+12) - 48" — no such prose exists in
  widgets/vat-review.ts. The skill body has the correct
  (10+11+12+30+31+32)-48 formula.
- "Including 'reversed' status entries in VAT aggregation may over-count
  cross-period storno" — current behaviour is correct per Skatteverket
  period-aligned filing: the reversed original stays in its own period,
  the matching storno (status 'posted') lands in the reversal period,
  and they net to zero across the full year. Adding code comment to
  document.

Tests: 2,623 passing (+6 for computeVatReport unit tests). Production
build green.

* fix(mcp): address PR #393 round-3 compliance review

Compliance bot re-ran after the round-2 push and flagged three items:

VAT computation
- One-sided reverse-charge warning previously only checked 2645 (EU
  acquisitions). For domestic reverse charge per ML 16:13 (byggtjänster,
  electronics > 100k SEK, etc.) the matching input lands on 2647 — a
  correctly-balanced 2614+2647 booking would have falsely fired the
  warning. Fixed: warning now triggers only when *both* 2645 and 2647
  are zero. Updated message text mentions both accounts. Added a test
  case asserting the no-warning path for 2647-only-input.

Skill documentation drift
- quarterly-vat-review skill body still showed ruta05 source as
  "3001 + 3002 + 3003" while the runtime computeVatReport sums 32 BAS
  taxable-revenue accounts. Updated the skill table to read
  "3001–3008, 3041–3048, 3051–3058, 3071–3078" so the auditor-facing
  docs match the implementation.

outputSchema upgrade
- gnubok_get_vat_report and gnubok_vat_review_widget previously declared
  outputSchema as the bare { type: 'object' }. Replaced with a shared
  VAT_REPORT_OUTPUT_SCHEMA constant declaring period, period_label, all
  11 rutor (with descriptions referencing source accounts), summary,
  and warnings. Modern MCP clients that validate structuredContent
  against outputSchema now have an accurate contract. Added a test
  asserting the schema is non-trivial and declares every ruta the
  runtime returns.

Tests: 2,625 passing (+2 for the 2647 warning path and the
outputSchema shape assertion). Production build green.

* fix(mcp): address PR #393 round-4 compliance review

The compliance bot re-ran after the round-3 push with a fresh batch.
Real findings fixed; false positives documented.

VAT computation
- Removed 3004 (Försäljning inom Sverige, momsfri / VAT-exempt) from
  RUTA_05_ACCOUNTS — round-2's expansion accidentally included it. Ruta 05
  is the *taxable* base; exempt sales must NOT contribute. New test pins
  the exclusion.
- Added 3106 (taxable EU goods supply, momspliktig) to RUTA_05_ACCOUNTS.
  Used when EU buyer's VAT number is invalid or buyer is private.
- Added ruta35 — EU intra-community goods supplies, momsfri (account
  3108). Previously omitted entirely from the rutor schema; SKV 4700
  has it as a distinct box separate from ruta 39 (services) and ruta 40
  (export outside EU). VatReportResult, VAT_REPORT_OUTPUT_SCHEMA, the
  widget table, the copy-summary block, and the quarterly-vat-review
  skill table all updated. New test covers 3108 → ruta35 mapping.
- Strengthened the comment on the posted+reversed status filter to
  document why current behavior is correct per ML 2023:200 and
  faktureringsmetoden (the bot's cross-period storno concern is a false
  positive — see commit message rationale below).

Skill content
- invoicing-rules: added explicit BFL 5 kap. 6–7 § / ML 17 kap. 22–23 §
  note that the kreditfaktura itself consumes a sequential number from
  the same (or dedicated KR-) fakturaserie. The KR- prefix is a display
  convention; the underlying löpnummer must be unbroken just like the
  regular series.
- payroll-monthly: added the missing "born 1937 or earlier → 0 %"
  cohort to the rate breakdown. Previously could lead a payroll run to
  over-pay avgifter on the oldest cohort.

False positives in the round-4 review (verified, not changed)
- 2644/2648 as reverse-charge inputs: verified against gnubok's actual
  BAS chart (lib/bookkeeping/bas-data/class-2-equity-liabilities.ts).
  2644 does not exist; 2648 is "Vilande ingående moms" (dormant input
  VAT for cash method), not RC at 6 %. Canonical RC inputs are 2645 (EU)
  and 2647 (domestic) — both already covered.
- Cross-period storno over-count: per ML 2023:200 + Skatteverket
  faktureringsmetoden, the original sale's VAT belongs to the invoice-
  date period; the kreditfaktura's reduction belongs to the storno-date
  period. Including 'reversed' status entries (which still have their
  original date) is therefore correct. *Excluding* them would
  under-report the original period and over-credit the reversal period.
  Added a multi-line comment in computeVatReport documenting this.

Tests: 2,627 passing (+2 for ruta35 mapping and 3004 exclusion).
Production build green.
