Three docker-gated tests for the full Neo4j compose stack:
* test_compose_neo4j_profile_healthy: docker compose
--profile neo4j up -d brings neo4j + lore-engine-ingest
+ lore-engine-mcp-neo4j to a healthy state within 60s.
* test_compose_neo4j_was_true_at_round_trip: was_true_at
through the Neo4j-backed MCP server returns the same
answer as the pickle-backed server for a known fact
(Roland Raventhorne / House Raventhorne / 3rd_age.year_345
→ was_true: true).
* test_compose_neo4j_down_cleans_volumes: docker compose
--profile neo4j down -v removes the neo4j_data volume.
docker-compose.yml changes:
* New neo4j:5 service with NEO4J_AUTH=none, loopback
HTTP + Bolt ports (17474/17687 by default to avoid
conflict with a developer's manual neo4j on the standard
7474/7687 ports), 1GiB mem_limit, pids_limit, healthcheck
via wget on the HTTP root.
* New lore-engine-ingest service (profile neo4j) that
runs scripts/01_ingest.py --skip-cognee --write-neo4j
after Neo4j is healthy. One-shot; no restart policy.
* The pickle-backed lore-engine-mcp service moved onto
the pickle profile (so it doesn't conflict on the
same host port when the neo4j profile is active).
* New lore-engine-mcp-neo4j service (profile neo4j)
that depends on both neo4j (service_healthy) and
lore-engine-ingest (service_completed_successfully).
Same hardening as the pickle service: cap_drop ALL,
no-new-privileges, mem_limit 512m, read_only rootfs,
tmpfs /tmp.
* Named volume neo4j_data for the Neo4j store.
Profile split (pickle | neo4j) keeps the two stacks from
colliding on the same host port when both are activated.
Run with docker compose --profile pickle up -d for the
default or --profile neo4j up -d for the production
graph substrate.
Slice 11.4 test update:
* tests/test_mcp/test_dockerfile.py test_docker_compose_up_and_round_trip
now uses --profile pickle so the pickle service
activates only.
Pre-prod hardening noted in compose yml: NEO4J_AUTH=none
is loopback-only; switch to a username/password and update
LORE_NEO4J_URI before exposing beyond loopback. Tracked in
docs/plan/05-slice-neo4j-backend.md.
Suite: 629 -> 632 passed (+3 compose-neo4j tests, all 559
baseline + 50 Neo4j + consistency + ingest + backend-switch
+ compose-neo4j tests preserved). The plan's 632 final-test
target is reached.
