chore - RFC 106 full graph/context conformance and evaluation

[dannymeijer]

Area

• Compiler (frontend/backend/codegen)
• Tooling (CLI/formatter/test runner)
• Editor integration (LSP/VS Code extension)
• Documentation

Summary

RFC 106 is a v0.6 full-scope commitment. The initial JSONL exporter and individual graph consumers are necessary but not sufficient: the release needs one conformance and evaluation contract spanning checked and tolerant export, LSP, Architect, MCP task context, process-risk facts, Rust/Incan inspection, and external ingestion boundaries.

Scope

• In scope:
  • A versioned compatibility corpus for required RFC 106 node, edge, provenance, identity, degraded-state, and snapshot/staleness semantics.
  • Cross-surface tests proving that CLI, live LSP, Architect, and MCP context use the same fact meanings and preserve source anchors, provenance, and stale-state behavior.
  • Hand-labelled task-context evaluation for precision, recall, budget use, determinism, freshness, broken-source behavior, and latency on stdlib-sized and workspace-sized projects.
  • Risk-signal evaluation with visible raw measures and a size or module control before any predictive claim.
  • Explicit evidence that external tools consume Incan facts without becoming a semantic authority.
• Out of scope:
  • Hosted indexing, mandatory embeddings, or a generic polyglot parser.
• Risks:
  • A passing exporter can still conceal divergent consumer semantics; this corpus must reject that split-brain outcome.

Plan

1. Define the full RFC 106 fixture matrix and expected graph/context records.
2. Exercise the matrix through every delivery child of feature - RFC 106 compiler-backed agent context graph #573.
3. Publish machine-readable results and human-readable limitations.

Done when

• Every full-scope RFC 106 delivery path passes the same compatibility corpus.
• Context packing and risk evaluation have recorded, reproducible results and limitations.
• Release evidence demonstrates one compiler-backed fact authority across all consumers.
