Tracking boundary

This directory contains the minimal reviewed intent. Optional participant prose and raw command logs are not required delivery output.

Implementation notes

Split cohesive parts out of the four large flat modules while keeping the original module names as backward-compatible facades:

• data2dsl_batch -> markdown rendering helpers extracted to data2dsl_batch_report (format_markdown_report re-exported from data2dsl_batch).
• data2dsl_cli -> command handlers extracted to data2dsl_cli_commands (_COMMAND_HANDLERS dispatch imported by data2dsl_cli).
• data2dsl_discovery -> graph builder internals extracted to data2dsl_discovery_graph; discover_data_network and DiscoveryError remain importable from data2dsl_discovery.
• data2dsl_skill -> MCP stdio transport (handle_mcp_message, main_mcp) extracted to data2dsl_skill_mcp with lazy skill import (no cycle); normalizer dispatch already lives in data2dsl_skill_norms (ticket-099).

Wheel py-modules declarations for the new modules landed via companion integration ticket-101 (shared contract path owned by integration workstream).

Verified: ./project/governance-check.sh GOV-PASS, python -m pytest -q 158 passed, lizard -C 15 src/ zero warnings.
