TDD step 2: markdown-table rendering with the load-bearing escape order
(backslash, then pipe, then newlines to spaces with CRLF as one unit),
SQL value-to-text conversion (NULL empty, plain-decimal integers,
shortest round-trip floats, explicit bool/BLOB rejection — never silent
coercion), and the verbatim fenced block for http bodies. Table shape
and fenced-block form match the reference implementation byte for byte
ahead of the shared §11 golden fixtures.

TDD step 1 of the phase 1 plan: typed error hierarchy rooted in
IngestError, manifest parsing with schema validation before any source
call — id grammar, polymorphic source types, extraction rules, verdict
reservation (okf_type and filename namespace), and the no-embedded-
credentials rule for base_url. Dev tooling (pytest/mypy/ruff) added as
a PEP 735 dependency group; runtime dependencies stay empty.
