Ports the GraphMCP-Example substrate into lore-engine-poc:
- 8 Go workers under workers/ (discord-connector, discord-filter, lore-watcher, ingestion-worker, entity-extractor, lore-extractor, encounter-processor, mcp-server), each with Dockerfile + go.mod
- 3 Go unit-test files (encounter-processor, ingestion-worker, lore-extractor) — other 5 workers rely on integration tests via the live stack
- plugins/nsc.py: thin httpx proxy from gateway to lore-mcp-server:9000, exposes all 11 inherited GraphMCP tools (input schemas verbatim from mcp-server/main.go)
- docker-compose.yml: adds lore-redis + lore-mcp-server + the 7 worker services (lore- prefix to avoid clash with other GraphMCP stacks)
- verify-merge.sh (171 LOC, 7 pass conditions) + docs/VERIFICATION.md
- tests/contract/test_graphmcp_tool_contracts.py (15 tests; skipped when stack is down — TDD pattern, becomes active once docker compose up brings the stack)
- README.md + test.sh updated for the merged service inventory
Leader notes (2026-06-27 03:50):
- Worker self-blocked review-required after 2 runs (run #7 hit 120/120 iteration budget; run #8 staged 40 files and reported shippable).
- Tests are SKIPPED until docker compose up — worker chose that pattern over mocking (consistent with the lore-engine-poc project convention). To activate, run `docker compose up -d --build && pytest tests/contract/`.
- File Scope reconciliation: story said gateway/plugins/nsc/__init__.py; worker shipped plugins/nsc.py (flat file). Justified by the existing plugins/ convention in lore-engine-poc (server.py glob("*.py")). A future PR could split nsc into a package once server.py learns __init__.py discovery.
- nsc plugin exposes 11 tools (not 8) — the AC said "8" but the worker enumerated all 11 tools present in mcp-server/main.go. The encounter-specific 3 tools (list_encounters, search_encounters, get_encounter) were included for consistency. Story AC #2 reads "≥ 8 GraphMCP tools" so this exceeds AC.
