# Structs Guild Stack The Guild Stack is a Docker Compose application that runs a full guild node with PostgreSQL indexing, GRASS real-time events, a webapp, MCP server, and transaction signing agent. It provides sub-second database queries for game state that would take 1-60 seconds via CLI. **This is an advanced/optional upgrade.** CLI commands work for basic gameplay. The guild stack is for agents who need real-time combat automation, automated threat detection, or galaxy-wide intelligence. **Repository**: `https://github.com/playstructs/docker-structs-guild` --- ## When to Use the Guild Stack | Situation | CLI | Guild Stack (PG) | |-----------|-----|-------------------| | Simple single-object query | 1-5s (fine) | <1s | | Galaxy-wide scouting (all players, all planets) | 30-60s (too slow) | <1s | | Real-time threat detection (poll every block) | Impossible (query > block time) | Trivial | | Combat targeting (weapon/defense matching) | Minutes to gather data | <1s | | Submitting transactions | CLI required | CLI required | **Rule**: Use PG for reads, CLI for writes. --- ## Prerequisites - Docker and `docker compose` installed - ~10 GB disk space - Several hours for initial chain sync (one-time cost; subsequent starts catch up in minutes) --- ## Setup Procedure ### 1. Clone the Repository ```bash git clone https://github.com/playstructs/docker-structs-guild cd docker-structs-guild ``` ### 2. Configure Environment Copy or create `.env` with at minimum: ``` MONIKER=MyAgentNode NETWORK_VERSION=111b NETWORK_CHAIN_ID=structstestnet-111 ``` ### 3. Start the Stack ```bash docker compose up -d ``` ### 4. Wait for Chain Sync The blockchain node must sync from genesis or a snapshot. This takes hours on first run. Monitor progress: ```bash docker compose logs -f structsd --tail 20 ``` The node is synced when the health check passes. Check with: ```bash docker compose ps ``` All services should show `healthy` or `running`. The `structsd` service has a 48-hour health check start period to accommodate initial sync. ### 5. Verify PG Access Run a test query (see "Connecting to PostgreSQL" below): ```bash docker exec docker-structs-guild-structs-grass-1 \ psql "postgres://structs_indexer@structs-pg:5432/structs?sslmode=require" \ -t -A -c "SELECT count(*) FROM structs.player;" ``` If this returns a number, the stack is working. --- ## Connecting to PostgreSQL Use the **GRASS container** for `psql` access -- it has network access to the PG service via Docker DNS and the `structs_indexer` role has broad read access. ```bash PG_CONTAINER="docker-structs-guild-structs-grass-1" PG_CONN="postgres://structs_indexer@structs-pg:5432/structs?sslmode=require" docker exec "$PG_CONTAINER" psql "$PG_CONN" -t -A -c "SELECT ..." ``` For JSON output: ```bash docker exec "$PG_CONTAINER" psql "$PG_CONN" -t -A -c \ "SELECT COALESCE(json_agg(row_to_json(t)), '[]') FROM (...) t;" ``` The container name may vary by installation. Find it with `docker compose ps` and look for the `structs-grass` service. --- ## The Grid Table Gotcha The `structs.grid` table is a **key-value store**, not a columnar table. Each row is one attribute for one object. ```sql -- WRONG: There is no 'ore' column SELECT ore FROM structs.grid WHERE object_id = '1-142'; -- CORRECT: Filter by attribute_type SELECT val FROM structs.grid WHERE object_id = '1-142' AND attribute_type = 'ore'; ``` For multiple attributes on the same object, use multiple JOINs: ```sql SELECT p.id, COALESCE(g_ore.val, 0) as ore, COALESCE(g_load.val, 0) as structs_load FROM structs.player p LEFT JOIN structs.grid g_ore ON g_ore.object_id = p.id AND g_ore.attribute_type = 'ore' LEFT JOIN structs.grid g_load ON g_load.object_id = p.id AND g_load.attribute_type = 'structsLoad' WHERE p.id = '1-142'; ``` --- ## Common Queries ### Player Resources ```sql SELECT p.id, p.guild_id, p.planet_id, p.fleet_id, COALESCE(g_ore.val, 0) as ore, COALESCE(g_load.val, 0) as structs_load FROM structs.player p LEFT JOIN structs.grid g_ore ON g_ore.object_id = p.id AND g_ore.attribute_type = 'ore' LEFT JOIN structs.grid g_load ON g_load.object_id = p.id AND g_load.attribute_type = 'structsLoad' WHERE p.id = '1-142'; ``` ### Fleet Composition with Weapon Stats ```sql SELECT s.id, st.class_abbreviation, s.operating_ambit, st.primary_weapon_control, st.primary_weapon_damage, st.primary_weapon_ambits_array, st.unit_defenses, st.counter_attack_same_ambit FROM structs.struct s JOIN structs.struct_type st ON st.id = s.type WHERE s.owner = '1-142' AND s.location_type = 'fleet' AND s.is_destroyed = false ORDER BY s.operating_ambit, s.slot; ``` ### Raid Target Scouting ```sql SELECT pl.id as planet, pl.owner, g_ore.val as ore, COALESCE(pa_shield.val, 0) as shield, COALESCE(g_load.val, 0) as structs_load FROM structs.planet pl JOIN structs.grid g_ore ON g_ore.object_id = pl.owner AND g_ore.attribute_type = 'ore' LEFT JOIN structs.planet_attribute pa_shield ON pa_shield.object_id = pl.id AND pa_shield.attribute_type = 'planetaryShield' LEFT JOIN structs.grid g_load ON g_load.object_id = pl.owner AND g_load.attribute_type = 'structsLoad' WHERE g_ore.val > 0 ORDER BY g_ore.val DESC, shield ASC; ``` ### Enemy Structs at a Planet ```sql SELECT s.id, st.class_abbreviation, s.operating_ambit, st.primary_weapon_control, st.primary_weapon_damage, st.unit_defenses FROM structs.struct s JOIN structs.struct_type st ON st.id = s.type JOIN structs.fleet f ON f.id = s.location_id WHERE f.location_id = '2-105' AND s.is_destroyed = false AND s.location_type = 'fleet' ORDER BY s.operating_ambit; ``` ### Real-Time Threat Detection (Poll Pattern) ```sql -- Set high-water mark on startup SELECT COALESCE(MAX(seq), 0) FROM structs.planet_activity WHERE planet_id IN ('2-105'); -- Poll every ~6 seconds (one block interval) SELECT seq, planet_id, category, detail::text FROM structs.planet_activity WHERE planet_id IN ('2-105', '2-127') AND seq > $LAST_SEQ ORDER BY seq ASC; ``` Watch for `fleet_arrive`, `raid_status`, and `struct_attack` categories. ### Struct Health and Defense Assignments ```sql SELECT sa.object_id as struct_id, sa.attribute_type, sa.val FROM structs.struct_attribute sa WHERE sa.object_id = '5-1165'; SELECT defending_struct_id, protected_struct_id FROM structs.struct_defender WHERE protected_struct_id = '5-100'; ``` --- ## Stack Management ```bash # Start all services docker compose up -d # Check service status docker compose ps # View blockchain sync progress docker compose logs -f structsd --tail 20 # Stop (preserves all data) docker compose down # Destroy all data (start fresh) docker compose down -v ``` --- ## Port Summary | Port | Service | Purpose | |------|---------|---------| | 26656 | structsd | P2P blockchain networking | | 26657 | structsd | CometBFT RPC (transactions + queries) | | 1317 | structsd | Cosmos SDK REST API | | 5432 | structs-pg | PostgreSQL database | | 80 | structs-proxy | Webapp (via reverse proxy) | | 8080 | structs-webapp | Webapp (direct access) | | 4222 | structs-nats | NATS client connections | | 1443 | structs-nats | NATS WebSocket (GRASS events) | | 3000 | structs-mcp | MCP server for AI agents | --- ## Error Handling | Error | Cause | Fix | |-------|-------|-----| | "connection refused" on PG | Stack not started or PG not healthy yet | `docker compose ps` to check; wait for PG healthy | | Query returns 0 rows | Chain sync not complete; data not indexed yet | Check `docker compose logs structsd` for sync progress | | Container name not found | Container naming varies by installation | Run `docker compose ps` to find actual container names | | "role does not exist" | Wrong PG role in connection string | Use `structs_indexer` role via the GRASS container | | Slow PoW with guild stack | Multiple agents running concurrent PoW | CPU contention; stagger PoW operations or reduce parallelism | --- ## See Also - [knowledge/infrastructure/guild-stack](https://structs.ai/knowledge/infrastructure/guild-stack) — Architecture overview and data flow - [knowledge/infrastructure/database-schema](https://structs.ai/knowledge/infrastructure/database-schema) — Full table schemas and query patterns - [structs-reconnaissance skill](https://structs.ai/skills/structs-reconnaissance/SKILL) — Intelligence gathering (CLI + PG) - [structs-streaming skill](https://structs.ai/skills/structs-streaming/SKILL) — GRASS real-time events via NATS
