Conversation
Port the codeanalyzer-typescript v0.4.0 Neo4j feature to Python under the
neo4j feature branch, with the same CLI arg entrypoints.
- codeanalyzer/neo4j: catalog (schema source of truth), project (pure IR ->
graph rows), cypher snapshot writer, incremental Bolt writer, and the
output-agnostic rows intermediate. Lazy neo4j-driver import keeps it off the
default json path.
- CLI: --emit {json,neo4j,schema}, --app-name, --neo4j-uri/-user/-password/
-database; -i/--input now optional for --emit schema.
- --emit neo4j writes a self-contained graph.cypher, or pushes incrementally to
a live Neo4j over Bolt; --emit schema emits the version-stamped schema.json
contract (checked in as schema.neo4j.json).
- Tests: schema-conformance (always runs, anti-drift guard) + opt-in Neo4j
Testcontainers bolt integration test (RUN_CONTAINER_TESTS=1).
- packaging/install/codeanalyzer-installer.sh: curl|sh installer (uv/pipx/pip).
- release.yml: sync schema.neo4j.json + publish schema.json and installer as
release assets. README/CHANGELOG updates; schema-uml.drawio. Version 0.2.0.

Summary
Ports the
codeanalyzer-typescriptv0.4.0 Neo4j feature to Python, keeping the same CLI arg entrypoints. One in-memory analysis can now be emitted three ways via--emit: the canonicalanalysis.json(default), a Neo4j property graph, or the version-stamped schema contract.What's included
