#015 — deeply nested JSON raised RecursionError (a RuntimeError, not
ValueError) and became an unhandled 500 on two paths:
- json-kind content validation now catches RecursionError -> 400.
- Added a custom DRF EXCEPTION_HANDLER
(artifacts/exception_handlers.py, wired via REST_FRAMEWORK) mapping
otherwise-unhandled RecursionError -> 400, covering the parser-level
crash on deeply nested request bodies (metadata etc.) too.
#016 — wrap_csv_viewer handed Grid.js rows without reconciling width to the
header, so over-long rows silently dropped cells. Now normalizes every row
to the max width: long rows widen the columns (auto-named "Column N"),
short rows pad with "". No cell is dropped.
Both verified live; 4 regression tests added. 106 tests pass.
