SCIP (Source Code Intelligence Protocol) ingestion.

Reads an index.scip file produced by an external indexer (rust-analyzer / scip-rust, scip-python, scip-ruby) and translates it into ckg Symbols + Edges with confidence 1.0 — these come from a real semantic indexer, not heuristics.

Mapping:

• SymbolInformation → Symbol (kind translated from SCIP Kind)
• Occurrence{role: Definition} → defines the symbol's location
• Occurrence{role: Import} → Imports edge from the document file → symbol
• Occurrence with no role bit set (a reference) → Calls edge from the enclosing definition → symbol
• SymbolInformation.relationships → Implements / Extends edges

Run an indexer first, e.g.: scip-rust index --output index.scip scip-python index . scip-ruby --index .

Then ckg index --scip path/to/index.scip.

Module layout

• parsing — path sanitization, qname extraction, symbol hashing
• mapping — SCIP Kind/role → ckg Kind, occurrence position helpers
• ingest — ingest_index main loop (document iteration, edge emission)
