The 4-bit LLM hallucinated my Halifax statement. A band-based parser fixed it.
bb finance's Phase H spike wired a 4-bit quantised Llama 3.2 1B as the primary PDF extraction route. On real Halifax statements it hallucinated at a destructive rate — page 3 has 34 transactions; the model returned something else. PF-002 disabled the LLM path and replaced it with a deterministic band-based parser that lands 54 of 54.
The dedup layer had three hash schemes. CDImportSource replaced them — and four banks validated with zero per-bank code.
The an iOS budget app import layer had three coexisting hash schemes with no shared contract between them. Collapsing them into CDImportSource — a unified source-attribution model — was the structural prerequisite for universal CSV and PDF parsers that validated across Monzo, Halifax, Revolut, and HSBC.
One parser for Monzo, Halifax, Revolut and HSBC: how heuristic matching beat four bespoke importers
The on-device LLM for PDF extraction hallucinated on a real Halifax statement. That failure produced a band-based parser that hits 54/54 transactions. The same heuristic approach on the CSV side means one importer, four banks, zero per-bank code paths.
