Lets a user upload a CSV, OFX/QFX, or PDF bank statement, parses the transactions, flags duplicates and possible transfers against existing records, and bulk-creates the accepted rows after a final read-only confirmation step. Backend - New `statements` module with CSV (papaparse), OFX/QFX (node-ofx-parser), and PDF (pdf-parse) parsers behind a `StatementParser` strategy interface; format detected by content sniffing + extension. - `DuplicateDetectorService` checks FITID/externalId exact matches first, then a date+amount+description Jaro-Winkler heuristic, then cross-account transfer pairing. - New `POST /statements/parse` (multipart, in-memory, 10MB cap) returns the parsed preview without writing, including per-row `status` (`new`, `duplicate`, `needs_review`, `possible_transfer`) and any `needsMapping` payload when CSV headers are unrecognized. - `POST /transactions/bulk` accepts up to 500 rows, chunks them 50 at a time inside `prisma.$transaction`, applies balance deltas, and writes a single `ActivityLog` row per chunk instead of one per transaction. - Schema: nullable `external_id` column on `Transaction` plus composite indexes on `(account_id, external_id)` and `(account_id, date)` for fast dedupe-window queries. Not encrypted — it's an opaque bank ID used as a lookup key. Frontend - `ImportStatementDialog` runs a 4-step wizard: Upload → Column Mapping (if needed) → Review (editable table with duplicate/transfer badges) → Confirm (read-only summary with projected per-account balance impact and count-bearing primary button). The Confirm step gates the actual write, and Back to Review preserves all edit/checkbox state. - New `bulkCreateTransactions` action on the transactions store. - "Import Statement" button added next to Export on the Transactions page, with a success toast and a refresh of the transactions + accounts stores. Tests - 306 backend tests (29 suites), 195 frontend tests (31 suites), all green. - Fixtures under `test/fixtures/statements/` cover three CSV sign conventions (signed-amount, debit/credit, credit-card), OFX 1.x SGML, OFX 2.x XML, and a credit-card QFX with the CCSTMTRS branch. Versions bumped to 0.4.0 on both packages per the lockstep rule. NOTE: the Prisma migration in `prisma/migrations/20260527203542_add_transaction_external_id/` still needs to be applied to the live database with `prisma migrate deploy` — the DB at 10.0.3.82 wasn't reachable from the dev environment.
