Summary

• Extends `ModelContextPackArtifact` with four optional provenance fields: `source_file`, `heading_path`, `char_count`, `reason_selected`. All existing callers remain valid — new fields default to `None`.
• Adds `GuidanceSectionParser` (`parsers/parser_guidance_section.py`) — a pure COMPUTE-eligible parser that splits guidance file text at ATX heading boundaries into typed `ParsedSection` objects, each convertible to a `ModelContextPackArtifact` via `to_artifact()`. Zero filesystem I/O: callers (EFFECTs) supply the raw string.
• 16 new unit tests cover heading parsing, nesting, provenance field storage, `to_artifact()` round-trip, and hash stability.
• OCC contract at `docs/work-tracking/contracts/OMN-12795.yaml`.

Evidence

• Tests: 16 new pass, full suite 6330 passed 0 failed (`-m "not kafka"`)
• mypy --strict on changed module: 0 issues (12 source files)
• ruff: all checks passed
• pre-commit: all hooks pass
• No filesystem I/O in parser: import-level grep confirmed (hashlib, re, dataclasses only)
• No deploy required: additive only — new optional model fields + pure COMPUTE parser, no node wiring, no bus topics, no container rebuild

Evidence-Source: OCC#2311
Evidence-Ticket: OMN-12795

Deployment

Additive only — no deploy, no shared-pin bump, no main promotion. Per plan §P2 parallelisation rules: feature→dev, no lane deploy until coordinated deploy.

Test plan

• `uv run pytest tests/nodes/node_context_pack_builder_compute/test_guidance_section_parser.py -v`
• `uv run pytest tests/ --tb=short -m "not kafka" -q`
• `uv run mypy src/omnimarket/nodes/node_context_pack_builder_compute/ --strict`
• `pre-commit run --all-files`
• Verify `gh pr checks` green
