build / build (push) Successful in 2m57s
Preprocessing now tries progressively heavier variants per receipt (plain -> high-pass -> edge-enhance -> both), stopping as soon as a cheap LLM-free arithmetic check on the OCR text looks plausible, so the extra processing only applies to receipts that need it. A flat version of the same heavier processing regressed the full batch by helping hard receipts but hurting easy ones; the adaptive version improves date-matching 37/52 -> 40/52 with no regression (see testing/2026_10_04_gimp_highpass_nlfilter_experiment.md). Also adds test_ocr.sh and test_single.sh for checking a single receipt's OCR text or full pipeline result without a batch run.

# Combines steps 1+2 (preprocess + OCR) adaptively: tries preprocess.py's
|
|
# variants cheapest-first (0=baseline, same as 1_preprocess_image.sh's
|
|
# default, up to 3=most elaborate), scoring each variant's OCR text with
|
|
# tooling-container/src/plausibility.py and stopping at the first one
|
|
# that looks receipt-consistent - no LLM call involved, so this costs
|
|
# nothing extra over the single-variant path for the receipts the
|
|
# baseline already reads correctly. See tooling-container/src/adaptive.py
|
|
# and testing/2026_10_04_gimp_highpass_nlfilter_experiment.md for why.

# Writes <out>/variant<N>/{01_gray,...,0X_final}.png and its own ocr.txt
|
|
# for every variant tried (for inspection - which variant was kept is in
|

# the printed summary) and <out>/ocr.txt (the winning variant's OCR
|
|
# text, ready for ./3_extract_data.sh).
