The OCR bundle installs paddleocr[doc-parser] 3.4, whose dependency closure drags
numpy 1.26.4 up to 2.5.1 and pulls scipy/scikit-learn/pandas wheels built against
the numpy 2.x ABI. build-bundle.sh re-pinned only numpy (basePackages), so those
numpy-2.x wheels stayed behind; the by-dir-name site-packages diff then shipped
them, and once merged onto the numpy==1.26.4 base they raise "numpy.dtype size
changed" on import.
Because the dispatcher pre-imports every ML library at startup and disables all AI
after 5 crashes in 60s, one stranded scipy takes down every AI tool, not just OCR
(observed on a CPU host: remove-background worked before the OCR bundle and broke
after). All-7 installs escaped it through last-writer-wins ordering; a subset
install did not, which is why it surfaced only intermittently.
Fix: add a manifest "constraints" list (numpy, scipy, scikit-learn, scikit-image,
pandas pinned to numpy-1.x-ABI versions) and apply it via PIP_CONSTRAINT to every
bundle pip install, so no bundle can pull a numpy-2.x wheel. paddleocr 3.4.1 still
resolves cleanly under the lock and the pinned stack imports without ABI error on
numpy 1.26.4 (validated on py3.12). Also import scipy/sklearn in the OCR path of
verify-bundle.sh so CI catches this class in isolation, and add a manifest
regression test.
Note: the published bundles must be rebuilt and republished (ai-bundles.yml) for
this to reach already-installed bases.

- Add || true after inference commands so set -e doesn't kill the
script before we reach the meaningful error message (exit code 3)
- Fix colorize settings: use "model" not "method" (matching colorize.py)
- Use larger font (size=40) and image (400x100) for OCR test so
PaddleOCR reliably recognizes the text
- Add || result="" fallback for stdout-capture smoke tests (OCR,
transcription) to prevent set -e on command substitution failure
- validate models field in bundle.json
- pipe JSON via stdin instead of triple-quote embedding (injection safety)
- add PNG magic byte validation for background-removal output
- add dimension assertion for upscale-enhance output
- add fixture existence guards before smoke tests
- use --no-index for offline fixup wheel install
Verifies bundle tarballs in 4 phases: SHA256 integrity, extraction
and install into the base venv, Python import checks per bundle,
and a functional inference smoke test per bundle.
