From f62c5332e37ee8fc625fed2fc60935630a135064 Mon Sep 17 00:00:00 2001 From: Viktor Barzin Date: Sun, 19 Apr 2026 11:52:59 +0000 Subject: [PATCH] meta_uk parser: add variant A (2019-2022) + variant C (2022-2023) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Context The initial v2 parser (commit 9741816) only handled the modern template (variant B, 2024+). Of Viktor's 73 real payslips in Paperless, 30 from 2021-07 through 2023-11 failed entirely — Claude fallback hit errors on them and the rows never landed. Investigation via `kubectl exec` + pdftotext on a sample of the failing docs revealed two previously-unseen layouts that the parser needs to handle directly: - **Variant A** (2019 → mid-2022): single-column Description/This Period/ This Year. Parenthesized negatives `(152.90)`. Date format `Date : 31 Aug 2021`. Employer is `Facebook UK Ltd` (not `Limited`). RSU lines: `RSU Gain Taxable` + `RSU Gain Nicable` + `RSU Net Cash UK` on the earnings side with a matching `RSU Net Gain` on the deductions side. BIK items (Private Dental/Medical) appear on both sides — net zero in the gross, but the deduction-side copy must land in other_deductions for the validation formula to hold. - **Variant C** (late-2022 → 2023): side-by-side Payments|Deductions| Year To Date (note capital "To", vs variant B's lowercase "to"). Date format `Pay Date : 30.11.2022` (dots, not slashes). RSU labels use the abbreviated `RSU Gain Taxabl` / `Nicabl` and still include the `RSU Net Gain` offset. `Company Name : Facebook UK Limited` preamble. Variant B (2024+) is unchanged. ## This change ### Parser refactor - `EMPLOYER_RE = re.compile(r"Facebook UK (?:Limited|Ltd)\b")` — matches all three eras. - `AMOUNT_RE` now accepts both `-1,234.56` and `(1,234.56)` — variant A's accounting-style parenthesized negatives normalize to `-1234.56` in `_to_decimal`. - `_parse_date` tries three formats in order: slash (B), dot (C), word (A). - `_is_variant_b_or_c` collapses B and C into one detector (both have the side-by-side header with `Year [Tt]o Date`); their parsers share code because the column mechanics are identical — only the RSU-label set and date format differ. - `_parse_variant_a` is a full rewrite: single-column rows split by the two `Total ...` anchors (payments → deductions), pay_date from the header's `Date : ...`, gross from first Total, net from the trailing `Net Pay` line, taxable_pay from the `Taxable Pay : This Period £X` line at the bottom. - RSU_VEST_LABELS is a shared set covering 8 aliases; rsu_vest sums every matching payment line. rsu_offset maps to `RSU Net Gain` on the deduction side when present (absent in variant B, present in A and C). ### Fixtures switched to real pdftotext output Removed the two synthetic fixtures that no longer reflected real Meta output (`meta_uk_2019_07.txt`, `meta_uk_2024_03_bonus_sacrificed.txt`) and replaced with real pdftotext captures: - `meta_uk_2021_08_variant_a.txt` (doc_id=43) - `meta_uk_2022_11_variant_c.txt` (doc_id=53) The remaining synthetic fixtures (`2025_03`, `2026_02`) stay because they encode specific bonus/no-bonus scenarios and the numbers are derived from the real Feb-2026 sample in the plan. ## Tests - 10 parser tests: one per variant (A/B/C) + totals validation across all 4 fixtures + the existing non-Meta/empty-input guards. All pass. - 52 total tests across the repo, all green. ## Test Plan ### Automated ``` $ poetry run pytest ============================== 52 passed in 1.66s ============================== $ poetry run ruff check . All checks passed! $ poetry run mypy . Success: no issues found in 24 source files ``` ### Manual verification (after deploy) 1. TRUNCATE + re-run backfill — expect 73 real payslips to extract via regex (≥95% hit rate), 42 → 70+ validated rows. 2. Sample a row for each variant via psql: employer, rsu_vest, and taxable_pay should all be populated. ## Reproduce locally 1. `poetry run pytest tests/test_meta_uk_parser.py -v` 2. Expected: 10 passed, each fixture validates totals to within 2p.
