⛔ Do not merge — LI-9759.

The pre-promotion mirror this branch was built from is carrying a corrupted custom-code seal that deletes generated model fields. Merging this PR would ship that regression to the published SDK.

Measured on llamacloud-prod-python, custom-code patch base → integrated, deletions of field declarations inside the models directory:

seal	count
clean, 2026-09-08	0
first poisoned, 2026-09-09	90
current	90

Affected surface includes custom_instructions, min_pages_per_split, pipeline_id, tier, parse_tier, total_pages, confidence, page_token, page_size, annotate_line_numbers.

The generator still emits all of these — every base tree has them, only integrated does not — and the spec never changed. It re-seals on every build, so it is current, not historical.

The public repos are clean; the last release (2026-09-08) predates the poison. That containment holds only while these promote PRs stay unmerged.

Unblock order: land the seal-corruption control → repair the affected mirrors → clean regenerate → then promote. Tracked in LI-9759, under LI-9748.
