MarkItDown 2Ways v0.2.0

MarkItDown 2Ways v0.2.0

Phase E adds conservative native round trips for proven-simple DOCX and PPTX table cells while preserving the fail-closed fidelity model established in v0.1.0.

Included

• identity Markdown tables can emit deterministic update_table_cells edits for changed coordinates only
• table-level semantic/native-locator preconditions plus per-cell old_text stale-write evidence
• DOCX simple table-cell text patching through existing native text carriers
• PPTX simple table-cell text patching through existing DrawingML text carriers
• semantic readback and native-target preservation verification for touched tables
• fail-closed handling for merged/spanned cells, nested tables, multi-paragraph cells, ambiguous carriers, structural/style/layout mutations, and charts
• hardening against Markdown boundary-whitespace loss, foreign local-name namespace spoofing, and mixed Transitional/Strict OOXML table namespaces

Scope

This remains a bounded two-way document layer, not a general Office editor. Table structure, style/layout, merged/spanned cell mutation, chart mutation, and unsupported complex native edits remain read-only or fail closed.

This is a fork-specific GitHub release tag. It does not replace or publish over the upstream markitdown PyPI package/version identity.
