Historical pipeline behavior — removed in 0.4.6

This page records retired behavior for migration, not a supported runtime contract. The notebook/script → AST metadata → FastAPI → Docker pipeline, its ASGI upload service and step plugins were removed in 0.4.6. Use the complete migration table.

The pre-removal characterization, limitations and measurements remain accessible in the 0.4.5 source. They do not describe current compiler eligibility, execution or exposure policy. The deprecation commit retains passing pipeline/HTTP/plugin characterizations before removal; retired-only tests no longer run against the new engine. Shared modern compiler characterization JSON remains in its original fixture tree.

The retained notebook exporter belongs to apizr.notebooks. Eighteen notebooks have immutable pre-move inputs and expected Python exports/formatting, including an unchanged magic refusal. Current source admission, cell selection, non-execution and mutation controls still apply. No modern coverage or security floor is removed; only the separate 59.5% floor for deleted src/apizr/modules is retired.
