A converter that writes hundreds of cells into someone else's spreadsheet has
to prove it afterwards, reading the OUTPUT back off disk rather than trusting
what the writer believes it did.
boq_engine/verify.py
- every formula the consultant had is still there (fatal)
- no sheet went missing (fatal)
- every write actually landed in the cell it claims (fatal)
- every source line accounted for (warn)
- nothing replaced without a human decision (warn)
- the workbook's own arithmetic recomputes (warn, optional)
populate() now records every cell it wrote, so the fidelity check reads back
real coordinates instead of sampling a guess.
A failed fatal check removes the download button outright. Recalculation needs
LibreOffice and is skipped cleanly when absent, so the container stays small.
New Verification tab shows the full check list plus a per-sheet table of what
the app decided about the columns - header row, item, description run, unit,
qty, rate, amount - so a wrong assumption is visible rather than invisible.
Also: aggregated the per-sheet TOTAL findings into one; fifty identical cards
is noise.
Reads our Candy PDF (deterministically, no OCR or model needed) and populates
the consultant's own workbook using their formulas, column layout and PAYMENT
column. Nothing is ever silently overwritten: every disagreement is reported,
can be settled inside the app, and regenerated.
- extract Candy text PDF -> tree (x-position column detection)
- template layout detect, sequence align, write, totals, overrides
- validate qty x rate and children-vs-subtotal reconciliation
- profiles per-consultant layout profiles, stored on a volume
Shipped with a Dockerfile + docker-compose for Coolify.
