* feat(documents): dedupe intake channels on content, not just provenance Every ingestion path already computes and stores sha256_hash, but only WhatsApp ever read it back: the manual upload, Resend inbound, and mail hunt deduped on provenance keys alone (or not at all), so the same receipt forwarded to two inboxes, re-hunted by a sweep, or uploaded twice became a second archived document and a second inbox item. With the hunt live and three channels feeding one inbox, that is an unbounded duplicate generator (flows plan, prerequisite PR 1). uploadDocument gains an opt-in dedupeByContent flag: before storing, it looks for a current-version document in the same company with the same SHA-256 and returns it (marked deduplicated) instead of archiving a copy. Opt-in because archival callers must store what they produced even when bytes repeat; the SELECT-then-insert race is accepted exactly as in the WhatsApp intake precedent. uploadAndExtract turns the flag on for every inbox channel. On a hit it adopts the oldest inbox item for that document, so callers always receive a real inbox_item_id, and only files a new item (against the EXISTING document) when the content entered the archive outside the inbox. The mail hunt skips outright: its provenance key catches the same message re-hunted, the content check catches the same receipt arriving through another inbox. WhatsApp keeps its own pre-check, which also drives the duplicate reply to the sender. No migration: the hash column and its index have existed since the original archive schema. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(documents): review round: fail closed, adopt-or-file in the hunt, audit trail CodeRabbit: both dedupe lookups failed OPEN, so a transient DB error would silently archive the duplicate the feature exists to prevent; both now throw before anything is stored, and a regression test locks it. The ingest test also asserts the dedupeByContent flag in the production call, so removing the flag fails the suite. Swedish compliance review, both findings real: (1) the mail hunt's unconditional skip could swallow a receipt whose content matches a document that never passed the inbox (a manually attached copy), leaving an affärshändelse without underlag routing (BFL 5 kap): the hunt now mirrors the funnel's adopt-or-file semantics, skipping only when an inbox item already carries the document and otherwise filing an item against the EXISTING document. (2) The skip decision now lands in behandlingshistorik as DocumentDuplicateSkipped (BFNAR 2013:2 kap 8), not just the app log. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(receipt-hunt): keep the audit payload pseudonymous; lock the skip trail in tests Review round 2. The DocumentDuplicateSkipped payload carried the mailbox address, violating the processing-history contract (pseudonymous IDs only, never emails); the digit-shaped PII validator would not have caught it, which is exactly why the contract must hold at the call site. Which mailbox first delivered the receipt is already on the existing item's channel_context. Tests now assert the audit event lands with the right identifiers and no address, and that a history outage still skips rather than filing a duplicate. Not changed: a duplicate-lookup error still soft-fails the attachment (warn + continue). Aborting the candidate would contradict this function's documented contract (one bad message never costs the night's hunt); fail-closed holds either way, and the next sweep retries since no item was filed.

Accounted
Open-source Swedish accounting software for sole traders (enskild firma) and limited companies (aktiebolag). Double-entry bookkeeping that complies with Swedish accounting law, built to be operated by you or by your AI agent.
Website · Hosted app · Documentation
Why Accounted?
Compliant by construction. Accounted implements double-entry bookkeeping under Swedish accounting law (Bokföringslagen). Voucher immutability, sequential voucher numbering, period locks, and 7-year document retention are enforced by database triggers, not by convention. Corrections are made the legal way, with reversal entries (storno), never by editing history. See ARCHITECTURE.md for how.
Agent-native. The full bookkeeping engine is exposed as 100+ MCP (Model Context Protocol) tools with scoped API keys, so an AI agent can do the books in Accounted: categorize transactions, draft vouchers, reconcile periods, and prepare declarations. Posting is staged for human approval, so the agent proposes and you decide.
Yours to run. AGPL-3.0 licensed and fully self-hostable with Docker and Supabase. Use the hosted version at app.gnubok.se or run your own.
