* feat(api): Phase 6 PR-2 — docs polish (Stripe-inspired) Ships the developer-facing documentation surface for the v1 REST API. Mirrors Stripe's structure (landing → cookbooks → concepts → reference → errors → changelog) at /docs/api with a sticky-sidebar layout in the gnubok editorial-monochrome aesthetic. Every page is also served as plain Markdown via a sibling .md URL so agents and LLM crawlers can ingest the same content without HTML parsing — the existing /llms.txt already promised /docs/api references that this PR makes real. Single source of truth for endpoint metadata is the existing Zod registry (lib/api/v1/registry.ts). The reference pages auto-generate from it: adding a new endpoint surfaces in the docs on the next build with no manual sync. The error reference pulls directly from lib/errors/structured-errors.ts STRUCTURED_ERRORS. CONTENT LAYER (lib/docs/): - content/landing.ts — introduction, auth, base URL, response envelope, the four core principles (dry-run, idempotency, strict-mode, inline audit), pointers to every other section. - content/versioning.ts — versioning + deprecation policy (Stripe dated format), idempotency, dry-run, strict-mode write semantics, inline audit blocks. - content/webhooks.ts — webhook concept guide. Full Node.js (express + crypto) and Python (Flask + hmac) signature-verification samples that match lib/webhooks/signing.ts exactly. Lifecycle, event-type catalogue, payload shape, request headers, common pitfalls, auto-disable behaviour, audit + retention. - content/errors.ts — generated from STRUCTURED_ERRORS. Groups by domain (generic, bookkeeping, periods, invoices, supplier-invoices, transactions, reports, imports, documents, salary, company, provider). Every code is anchorable so the docs_url field on every error envelope finally points somewhere real. - content/reference.ts — generated from listEndpoints(). Groups by resource (companies, customers, invoices, suppliers, supplier-invoices, transactions, journal-entries, fiscal-periods, accounts, documents, employees, salary-runs, reports, imports, compliance, webhooks, operations, voucher-gap-explanations, reconciliation). Each endpoint section: summary, description, useWhen, doNotUseFor, pitfalls, scope, idempotent/reversible/dry-run flags, request + response examples. - content/changelog.ts — initial entry for API version 2026-05-12 covering every endpoint shipped in Phases 1-6. Lists what's coming in Phase 6 PR-3 (hardening + remaining cookbooks). - content/cookbook/quickstart.ts — five-minute send-your-first-invoice guide. Demonstrates auth, dry-run, idempotency, audit-block patterns in one continuous narrative. - content/cookbook/webhooks.ts — end-to-end webhook setup, sig verification, retry handling, idempotency on receiver side, replay patterns, auto-disable behaviour. Companion to the concept page. - content/cookbook/index.ts — recipe registry. 4 placeholder recipes (ingest-bank-transactions, file-vat-declaration, run-payroll-and-agi, year-end-closing) link to their reference pages with a "coming after Phase 6 PR-3 hardening" note. Narrative cookbook quality benefits from a focused pass after the substrate stabilises. - nav.ts — single source of truth for the sidebar nav, used by the layout AND the landing-page resource grid. - markdown.tsx — shared <DocsMarkdown> component using react-markdown (already a dep) with Hedvig serif headlines, Geist mono code blocks, hairline section borders, paper-white surfaces — same editorial aesthetic as the dashboard. LAYOUT (components/docs/DocsLayout.tsx): Two-column sticky-sidebar layout. Top header carries the gnubok mark + section links (API reference, Cookbooks, Errors, Changelog, openapi.json). Sidebar groups: Getting started, Cookbooks, Concepts, API reference, Reference. Active page highlighted with the same warm-beige bg the dashboard sidebar uses. ROUTES (app/docs/api/, app/llms-full.txt/): - /docs/api → landing - /docs/api/errors → error reference - /docs/api/webhooks → webhook concept - /docs/api/versioning → versioning + idempotency + dry-run - /docs/api/changelog → release notes - /docs/api/reference → resource overview - /docs/api/reference/[slug] → per-resource pages (19 resources, all generated from the registry; generateStaticParams listed) - /docs/api/cookbook/[slug] → recipe pages (8 entries, 2 fully written + 6 aliases/placeholders) - /llms-full.txt → everything concatenated for one-shot LLM ingestion Every page has a sibling .md route (e.g. /docs/api/errors.md) serving the raw Markdown for agents — same content, no HTML wrapper, same 5-min cache. Honours the existing /llms.txt promise that "every .md URL under /docs/api is served as plain Markdown". CI GUARD (lib/api/v1/__tests__/spec-snapshot.test.ts): Vitest snapshot test that locks down (a) the endpoint count, (b) the sorted set of method+path keys, (c) the set of distinct scopes referenced. CI fails if any drift unexpectedly so a Zod-schema change can't ship a silent API break — when you intentionally add/remove an endpoint, run with -u to refresh the snapshot, review the diff, and commit alongside the route change. The snapshot diff itself is a self-describing changelog entry. Initial snapshot: 100 endpoints, 17 distinct scopes, full key set sorted. Fourth assertion in the test guarantees every endpoint declares the agent-facing metadata (summary, description, useWhen, doNotUseFor, pitfalls, example) the reference pages depend on — so a registerEndpoint call that omits any of these fields is caught at CI time rather than rendering an empty section in the docs. INFRA TOUCH (lib/api/v1/load-routes.ts): Added the 5 Phase 6 webhook route imports so the registry includes them on the docs builders' path. Required for the /docs/api/reference/ webhooks page to render. The webhook routes' registerEndpoint calls already exist; this just side-effect-imports them where the spec generator can see them. Coming in Phase 6 PR-3 (hardening — separate PR): - 90-day TTL cleanup cron for non-accounting webhook deliveries - claim_due_webhook_deliveries SQL function (FOR UPDATE SKIP LOCKED) - Per-route rate limits on :test, :retry, webhook :create - V16 audit-log on webhook lifecycle events - DNS-rebinding pinned-IP HTTPS agent - Integration tests for webhook routes + *.pg.test.ts for triggers - Populated previous_attributes for update-style webhook events - The remaining 4 cookbook recipes (ingest-bank-transactions, file-vat-declaration, run-payroll-and-agi, year-end-closing) once the engine surface is fully stable. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor(api): address PR-497 review round 1 — CI fix + 5 small docs items CI BLOCKER (the reason core-only failed): 1. **Type error on `[slug].md/route.ts` dynamic routes** — Next.js 16's route-type inference can't extract the dynamic segment from a directory whose name contains a literal suffix like `[slug].md/`. It types `params` as `Promise<{}>` and rejects our handler that declares `params: Promise<{ slug: string }>`. The framework still ROUTES requests correctly (URL `/docs/api/cookbook/quickstart.md` reaches the handler) — only the typed `params` is unusable. Fix: drop the typed `params` parameter on the two affected handlers (cookbook + reference) and parse the slug from `request.url.pathname` directly. Inline comment documents the workaround so the next person to touch these doesn't try to "fix" it back to the typed pattern. GREPTILE INLINE (2 items): 2. **Python sample was missing `import json` and `import os`** — the webhook signature-verify sample uses both but only imported `hmac`, `hashlib`, `time`, and `flask`. Added the two missing imports. 3. **`buildResourcePages()` perf — called twice per request** (P2). Each call iterates every registered endpoint, groups by resource, sorts, and serialises Markdown for all 19 resource pages. Memoised at module level — the registry is populated once at module load and immutable for the process lifetime, so a single derivation is safe to cache. Halves the cost on the HTML routes' `generateMetadata` + page render pair, and the .md route handlers (which Next.js doesn't statically pre-render) are now constant-time after the first GET. SWEDISH-COMPLIANCE PRECISION (3 items): 4. **`webhooks.ts`: behandlingshistorik vs räkenskapsinformation distinction.** The previous "Audit + retention" section conflated the two — webhook delivery rows are *behandlingshistorik* (system- event log) per BFNAR 2013:2 kap 8 §, NOT räkenskapsinformation themselves. The 7-year retention from BFL 7 kap 1 § attaches to the underlying verifikation/faktura/AGI XML in its own table, not to the delivery envelope. Updated the section to draw the distinction and clarify gnubok's 7-year retention on accounting-event delivery rows is an operational audit-trail policy, not a statutory obligation passed through to the integrator. 5. **`changelog.ts`: same distinction in the Phase 6 PR-1 entry** — replaced the "räkenskapsinformation" framing with the correct behandlingshistorik framing + the operational-policy note. 6. **Quickstart cookbook: ML 17 kap 24 § p.8 note about `beskattningsunderlag per skattesats`.** The "What just happened" section now explicitly notes that the rendered PDF contains every ML 17 kap 24 § field (including taxable amount per VAT rate) and that the JSON response's summary fields are convenience aggregates for the integration — the binding faktura content is the PDF. Forecloses the misreading that `subtotal + vat_total` is sufficient compliance. 7. **Changelog: BFL 7 kap caveat on SIE export.** The `/reports/ sie-export` line now warns that a SIE4 export alone does NOT satisfy BFL 7 kap archiving obligations — SIE captures account positions and verifikationer but lacks system documentation and behandlingshistorik. Treat as a portability format (Fortnox/Visma/Bokio migration), not as a complete archive. Closes the misreading the swedish-sie-import-export skill flagged. DEFENSIBLE DEFERS (round 1 final): - **CM-8 SPDX-License-Identifier headers per file** (Compliance Swarm). The repo declares AGPL-3.0-or-later in the root LICENSE file, which satisfies licensing for the project as a whole. Per-file SPDX headers are a REUSE-conformance feature; we can address as a sweep across the entire codebase if/when REUSE conformance becomes a requirement. Out of scope for a docs PR. - **`/llms-full.txt` exposes payroll endpoint metadata publicly** (A.8.12). By design — the entire point of the file is one-shot LLM ingestion of the public docs corpus. Endpoint METADATA (path, scope, description) is non-sensitive; actual payroll DATA is gated behind `payroll:read` scope and requires a real API key. Adding an auth gate would defeat the agent-discovery purpose. - **Secret rotation endpoint** (Art.25(2)). Real product gap (delete + recreate is the current rotation path), but it's feature work, not docs. Tracked for Phase 6 PR-3 alongside the other webhook hardening. - **DNS rebinding pinned-IP HTTPS agent** (Art.5(1)(f)). Already documented in this changelog as a Phase 6 PR-3 item; bot is just re-flagging that it's not yet shipped. - **A.5.34 changelog cites GDPR Art.5(1)(c) for personnummer masking without linking privacy policy.** The citation is informational context for developers, not a privacy notice to data subjects. Data- subject notices live at /privacy. Adding a pointer is reasonable; adding it would consume real estate that's better spent on the technical detail. Defer. - **Compliance Swarm A.5.21 third-party attribution in llms-full.txt**. False positive — all markdown content in this PR is original first-party text. No third-party snippets to attribute. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor(api): address PR-497 review round 2 — 6 small precision fixes All CI green after round 1 (core-only fixed). Compliance Swarm: 7 → 10 findings is the documented oscillation pattern — net-new actionable items are 6 small fixes; the rest are recurring defers (plaintext-secret variants, SPDX, planned PR-3 features the changelog already lists as "coming soon"). FIXED: 1. **Slug allow-list validation in `[slug].md` routes** (V1.2.5 ×2, medium). The cookbook + reference .md routes parse the slug from the URL pathname (round-1 workaround for Next.js 16's failed inference on `[slug].md/` directories) and pass it to a dictionary-based lookup. The lookup itself is safe — findRecipe / buildResourcePages can't reach SQL or filesystem from a bad slug — but the explicit allow-list gate keeps the contract safe if the lookup mechanism ever changes (file-load, RPC, etc.). Added `Set<string>(COOKBOOK_SLUGS)` + `Set<string>(RESOURCE_SLUGS)` guard before any lookup runs. 2. **Changelog: BFL 5 kap 5 § cited on both `/reverse` AND `/correct`** (swedish-compliance precision). The previous wording cited BFL 5:5 only on `/reverse` (storno) and described `/correct` as plain "rättelse" — but BFL 5:5 governs rättelse generally, and storno is the canonical method of rättelse, so both endpoints satisfy 5:5. Updated to: "/{id}/reverse (storno) and /{id}/correct (rättelse) — both satisfy BFL 5 kap 5 § (storno is the canonical method of rättelse)". 3. **Changelog AGI: explicit that XML is for manual submission** (swedish-compliance / swedish-payroll). Previously said "/generate-agi produces AGI XML" — could be misread as auto-submission to Skatteverket. Now states explicitly that the response carries `data.xml` for the integrator to upload via Skatteverket Mina Sidor (or via the optional `skatteverket` extension), and that the AGI deadline (12th / 17th of the following month) is the integrator's responsibility. Aligns with the route file's existing doNotUseFor + pitfalls metadata. 4. **Quickstart: F-skatt note qualified** (swedish-invoice-compliance). The "What just happened" section previously said the PDF "contains the F-skatt note" — only valid if the seller actually holds F-skatt. Updated to: "The 'Godkänd för F-skatt' note is included automatically when company_settings.has_f_skatt is set — confirm this on the company settings page before sending invoices in production." Also tightened the beskattningsunderlag wording to mention "one line per distinct rate on multi-rate invoices" — closes the swedish-compliance note about the multi-rate claim in the landing needing explicit support in the cookbook. 5. **Cookbook placeholder VAT description: "compute and review" not "submit"** (swedish-vat). The placeholder previously said "Compute momsdeklaration rutor and submit to Skatteverket" — but no Skatteverket-submission endpoint exists in the v1 surface; the API only computes the rutor 05–62 values for manual filing. Updated description in BOTH cookbook/index.ts AND nav.ts (where the same string was duplicated): "Compute momsdeklaration rutor 05–62 and reconcile against the GL before manual submission to Skatteverket." Title also flipped from "File a VAT declaration" to "Compute and review a VAT declaration". 6. **Cookbook nav for AGI: aligned to "generate" semantics**. nav.ts AGI summary used to say "file AGI" — same misreading risk as #3. Now: "Calculate, approve, mark paid, book, generate AGI XML for manual Skatteverket upload." DEFERS (round 2 final — every remaining swarm finding is in one of these buckets): - **🟠 Art.32 plaintext webhook secret + 4 sibling framings** (V14, V11.1, A.8.24, CC6.1). Established defer per Stripe / GitHub / Slack precedent; documented inline in lib/webhooks/signing.ts. Bot is re-flagging via the docs surface this round; underlying position unchanged. - **🟡 Art.5(1)(e) 90-day TTL non-accounting cron + V16 audit log + V2.4 rate limits**. All explicitly listed in the changelog as "Coming soon (Phase 6 PR-3 hardening)". Bot is reading the same text we wrote; not blocking. - **🟠 A.8.11 personnummer masking lacks an automated test**. Real product-hardening request, but it's feature work in the employees test surface, not docs. Tracked. - **🟡 CM-8 SPDX-License-Identifier headers per file**. Established defer from round 1 — root LICENSE covers AGPL-3.0-or-later for the project as a whole; per-file SPDX is a REUSE-conformance sweep that's its own effort. - **🟡 SR-3 SBOM dependencies**. False positive — next/server, react, next/link, next/navigation are existing project deps, not new in this PR. - **swedish-compliance "SIE disclaimer could note immutability requirement"** — the current disclaimer accurately calls out system documentation + behandlingshistorik as missing; adding immutability would over-stuff a one-line caveat. Defer with the understanding that the SIE skill itself documents the immutability requirement for any consumer that follows the reference. If round 3 plateaus (Compliance Swarm count stable, no net-new inline items), that's the merge-ready signal per Phase 4 lessons. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor(api): address PR-497 review round 3 — 4 small precision fixes Compliance Swarm: 10 → 3 (down 70%) — net-new actionable items are the 4 below; remaining 3 swarm findings are either trivial defense- in-depth (URL decode, fixed here) or out-of-repo decisions (personnummer disclosure DPO confirmation). FIXED: 1. **URL-decode slug before allow-list check** in both .md route handlers (V1.2.5 ×2 low). The closed allow-list is pure ASCII so a percent-encoded value can't decode to a legitimate slug, but the explicit decode-then-check pattern keeps the contract correct under any future encoding-quirk runtime. try/catch around decodeURIComponent so a malformed % sequence (which throws) returns a clean 404 rather than a 500. 2. **Quickstart: explicit `delivery_date` requirement** (swedish- invoice-compliance / ML 17:24 field 7). The previous wording listed "supply date" as a covered field but didn't note that the API does NOT default delivery_date to invoice_date — integrators shipping invoices for goods delivered on a different date than the invoice date must pass delivery_date explicitly or the rendered PDF is non-compliant. Added explicit pass-it-yourself note. 3. **Quickstart: F-skatt strengthened from "verify" to "legal requirement"** (swedish-invoice-compliance / Peppol BIS 3.0 SE-R-005). The previous "confirm on settings page" wording risked integrators treating the F-skatt note as optional UX. It's a legal requirement on every faktura issued by a company that holds F-skatt registration — and a FATAL Peppol BIS 3.0 validation failure (SE-R-005) for B2G invoices when missing. Reframed as a compliance assertion: the PDF includes it automatically when the setting is true; verifying the setting is correct before production is the integrator's responsibility. 4. **Changelog: SIE post-import VAT code reconfiguration warning** (swedish-sie-import-export). The /imports/sie line previously noted the file format support but didn't warn that SIE files do NOT carry VAT codes or tax-rate-to-account mappings. After migrating from Fortnox / Visma / BL / SpeedLedger / Bokio, integrators must manually reconfigure VAT codes before the first momsdeklaration — skipping this is the most common source of incorrect VAT submissions in migrated bookkeeping. DEFERS (round 3 final — these are the architectural floor): - **🟠 A.5.34 personnummer field name + masking logic disclosed in public docs** (Compliance Swarm). Defensible: documenting that personnummer is masked is a transparency benefit (GDPR Art.13/14 intent), not a privacy disclosure risk. The DPO confirmation prompt is a reasonable governance ask but is an out-of-repo decision — the docs change is appropriate as written. - **AGI penalty amounts (625 / 1,250 SEK)**. Operational guidance for integrators building deadline-tracking; not strictly API-doc material. The deadline (12th / 17th) is documented; integrators who automate compliance can read SFL for penalties. - **VAT period thresholds in the cookbook placeholder**. Belongs in the actual cookbook content when written, not in the placeholder description. - **`invoice.credited` event-naming verification**. False positive — the emitter uses `credit_note.created` (which IS in the docs); there is no `invoice.credited` event in the codebase. Naming is consistent. - **Webhook retention sentence reordering** (swedish-compliance stylistic). Current wording leads with what delivery rows ARE (behandlingshistorik), then clarifies what they are NOT (räkenskapsinformation) — clean teaching arc, the qualifier is prominent. Reordering doesn't change clarity. Round 3 stop signal hit (per Phase 4 lessons): swarm count plateauing at the architectural floor with all remaining findings either defers, false positives, or out-of-repo decisions. Greptile has posted no inline comments since round 1's two items (both fixed). This should be merge-ready. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor(api): address PR-497 review round 4 — 5 small precision fixes Compliance Swarm: 3 → 5 (slight uptick from oscillation, but 0 critical, 1 actionable; remaining 4 are recurring or philosophical). swedish-compliance: 7 advisories — 3 actionable precision items incorporated below; the others are forward-looking notes for cookbook content that ships in Phase 6 follow-ups. FIXED: 1. **Spec-snapshot test enforces ep.scope is explicitly defined** (CC6.3, real future-bug prevention). Previously the test asserted every endpoint declared the agent-facing metadata fields the docs depend on, but `scope` could be `undefined` — a registerEndpoint call that silently dropped the field would make the wrapper treat the route as unauthenticated. Added an assertion that `ep.scope !== undefined` (the literal sentinel `null` is allowed for genuinely public endpoints like /api/v1/health). The 4 spec tests still pass — confirming no current endpoint has undefined scope and the gate works prospectively. 2. **F-skatt: integrator responsibility for `has_f_skatt` accuracy** (swedish-invoice-compliance). The previous "verify on settings page" framing didn't connect the flag to the live Skatteverket registration. Now: "The integrator is responsible for keeping has_f_skatt in sync with the company's live Skatteverket registration status. Update via PATCH /api/v1/companies/{id}/ settings or the settings page — a flag that's false while the company is actually F-skatt-registered produces non-compliant invoices, not merely a missing optional note." 3. **AGI deadline qualified by turnover** (swedish-payroll). The previous wording listed "12th / 17th of the following month" with no condition. Now: "12th of the following month for large employers, 17th for companies with annual turnover ≤ 40 MSEK." Aligns with the swedish-payroll skill's AGI filing deadline section. 4. **SIE import warning includes behandlingshistorik gap** (swedish-sie-import-export + swedish-accounting-compliance). The previous warning covered the VAT-code reconfiguration requirement but didn't note that SIE files also do NOT transfer behandlingshistorik (the source system's processing log per BFNAR 2013:2 kap 8 §) or systemdokumentation. Added: "The behandlingshistorik gap must either be preserved separately (export from the source system + archive alongside the SIE file) or accepted with documented justification — gnubok starts a fresh behandlingshistorik from the import date forward." 5. **Webhook 7-year retention: voluntary policy vs statutory obligation** (swedish-accounting-compliance). The previous wording said gnubok keeps delivery rows "for 7 years as an operational audit-trail policy" — the 7-year figure could be misread as statutory. Tightened in BOTH webhooks.ts and changelog.ts: the 7-year statutory retention under BFL 7 kap 1 § applies ONLY to the underlying verifikation/faktura/AGI XML; gnubok's 7-year policy on delivery rows is voluntary and chose the duration to align conveniently with the statutory horizon on the underlying records. DEFERS (round 4 final, all in the architectural-floor bucket): - **🟠 A.5.34 personnummer field name + masking logic disclosed in public docs** (recurring from round 3). Defensible — documenting PII handling is a transparency benefit (GDPR Art.13/14 intent), not a privacy disclosure risk. The DPO confirmation prompt is a reasonable governance ask but is an out-of-repo decision. - **🟡 A.8.23 DNS-rebinding "coming soon" item**. The bot is reading the changelog's own deferral list. Already tracked for Phase 6 PR-3 hardening. - **🟠 CC6.6 SSRF protection details exposed in /llms-full.txt**. Stripe / GitHub / Slack publish their full webhook security posture publicly (signature format, rejected IP ranges, retry policy) — documenting protections IS the trust pattern. Obscurity is not security; the SSRF protection is enforced in code, not in the docs. - **🟡 CC6.7 public CDN caching**. withPublicSecurityHeaders() already applies the appropriate headers (CSP, X-Content-Type- Options, X-Frame-Options). The 5-min cache is appropriate for static developer documentation; the alternative (no caching) is cost without security benefit since the content is intended to be public. - swedish-compliance "VAT 2026-04-01 livsmedel rate change" — forward-looking; ships when the actual VAT cookbook is written. - swedish-compliance "year-end IB/UB continuity" — forward-looking; ships when the year-end cookbook is written. - 2 verify-only notes (rättelse implementation, future salary- journal/avgifter-basis masking sweep) — not actionable in this PR. Round 4 stop signal: every remaining swarm finding is in the deferred or recurring bucket; the actionable item (CC6.3) is shipped. swedish-compliance is now in advisory mode (no errors, just stylistic suggestions and future-cookbook notes). Per Phase 4 lessons, this is the merge-ready signal. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor(api): address PR-497 review round 5 — 4 small precision fixes (last actionable items) Compliance Swarm: 5 → 2 (down to architectural floor — 1 high + 1 medium). swedish-compliance: 7 advisories, 4 actionable precision items addressed below; the others are forward-looking notes for content that ships in Phase 6 follow-ups. Trajectory: 7 → 10 → 3 → 5 → 2. Plateaued. FIXED: 1. **Webhook secret storage guidance: secrets manager, not env file** (A.8.5 high). Added explicit instruction to the cookbook that the returned secret is signing material and must live in a secrets manager (AWS Secrets Manager, GCP Secret Manager, HashiCorp Vault, Doppler, 1Password Connect, ...) — not a plaintext .env file or config commit. Treated with the same care as a database password. 2. **AGI deadline correction: 17th = January and August only** (swedish-payroll). Round 4's wording said "12th (large employers) / 17th (≤40 MSEK)" — but per the swedish-payroll skill the 17th applies in January and August specifically, not generally to all months for sub-40 MSEK companies. Other months are the 12th regardless of employer size. Fixed to: "the 12th of the following month for every reporting period EXCEPT January and August, where companies with annual turnover ≤ 40 MSEK get the 17th." This would've caused integrators automating sub-40 MSEK deadline tracking to misfile by 5 days from February through July and September through December. 3. **F-skatt SE-R-005 broader scope** (swedish-invoice-compliance / swedish-e-invoicing). The previous wording framed SE-R-005 as primarily a Peppol B2G validation rule. Reframed: the F-skatt note is a legal requirement on every faktura issued by a Swedish momsregistrerad seller that holds F-skatt registration — applies to PDF/paper AND Peppol/e-invoice formats. The buyer uses it to determine A-skatt withholding obligation (omitting it can shift tax liability onto the buyer); B2G is just where the validation is automated as a FATAL Peppol BIS 3.0 check. 4. **SIE behandlingshistorik gap: full räkenskapsår scope** (swedish-accounting-compliance). Round 4's wording said the integrator "must either preserve [behandlingshistorik] separately or accept the gap with documented justification" and that gnubok "starts a fresh behandlingshistorik from the import date forward." The "documented justification" framing implied the gap was acceptable as a default. Per BFNAR 2013:2 kap 8 §, the obligation attaches to the entire räkenskapsår, not from the import date. Reframed as: "must be preserved separately... best practice for a mid-year migration: export the source system's behandlingshistorik for the full fiscal year and archive it alongside the SIE file." DEFERS (round 5 final — these are the architectural-floor items that will recur indefinitely): - **🟡 A.8.20 DNS-rebinding gap** (Compliance Swarm). Already documented in the changelog as a Phase 6 PR-3 deferral item; the bot is reading the same text we wrote. - **swedish-compliance: VAT 2026-04-01 livsmedel rate change**. Forward-looking — for the actual VAT cookbook recipe content, which ships post-Phase-6. - **swedish-compliance: year-end IB/UB continuity**. Forward-looking — same. - **swedish-compliance: SIE warning placement note**. Forward-looking — for the imports reference page when authored. - **swedish-compliance: BFNAR 2013:2 citation correct, webhook retention correct**. No-op confirmations. - **swedish-compliance: delivery_date pre-payment scenario**. Real but extremely narrow edge case (faktura utfärdad före leverans). Defer with the understanding that anyone using the API for pre-payment invoicing will read the full invoice reference, not rely solely on the quickstart. This is the merge-ready signal per Phase 4 lessons-learned: every remaining swarm finding is in the deferred or recurring bucket; swedish-compliance is in pure-advisory mode (forward-looking notes for cookbook content that ships later); CI is fully green; Greptile posted nothing past round 1's two items (both fixed). Ship it. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
