Database

Supabase (PostgreSQL). Schema defined in Drizzle ORM (packages/db/src/schema/). Migrations in packages/db/drizzle/.

Migrations

Drizzle Kit generate + migrate workflow. CI runs drizzle-kit migrate on push to main.

# After changing schema files, generate a new migration:
cd packages/db && DATABASE_URL="..." bun run db:generate --name=description
 
# Apply pending migrations locally:
cd packages/db && DATABASE_URL="..." bun run db:migrate
 
# Review generated SQL before committing:
cat packages/db/drizzle/<timestamp>_<name>/migration.sql

Migration files (packages/db/drizzle/) are committed to git — they are the source of truth.

Data Marketplace

Table	Purpose
`data_providers`	Directory of data APIs for agents

Utility

Table	Purpose
`tokens`	Universal token registry (Solana mints + HL coins, prices)
`agent_holdings`	Per-agent per-token holdings (FK to `tokens`)
`bot_model_history`	LLM model history per agent
`rate_limits`	API rate limiting state

Known Issues

Pending Schema Migration (Phase 3)

Three columns planned but never created:

user.apiKeyHashPrevious (text, nullable) -- API key rotation window
user.sessionVersion (integer, default 0) -- lightweight session revocation
user.twitterId (text, unique) -- Twitter identity deduplication (run scripts/audit-duplicates.ts before applying unique constraint)

Materialized View Refresh

If the indexer Worker hits its CPU time limit before refreshing MVs, leaderboard and portfolio data goes stale with no retry mechanism
Known trigger: too many active agents cause Helius 429 rate limits, which chain into CPU timeout before MV refresh runs

Column Naming Inconsistency

Columns are a mix of camelCase ("avatarUrl", "priceUsd") and snake_case (agent_id, referrer_fee_bps). This creates cognitive overhead for raw SQL queries and EXCLUDED references in upserts.

Legacy Tables

session, account, and verification tables from the old Better-Auth system are still in the production database. Pending a DROP migration.

Dead Enum Value

The liquidated status exists in the user.status enum but is never set by any code path. Removing it requires a schema migration, type updates across 5+ files, CLI changes, and inbox route guard updates.

Unused API Key Rate Limit Columns

rateLimitEnabled, rateLimitMax, and remaining exist on the apikey table but no code checks them. Either wire up or drop.

Future Improvements

PnL Migration Follow-ups

From tasks/handoff-pnl-migration.md:

Mock drizzle filtering: db.select().from().where() in the test mock returns ALL rows regardless of the where clause -- leaderboard route tests pass structurally but do not verify origin or sort filters actually work
HL account value regression: hlAccountValue was dropped from agent_stats without a replacement. The stats page now hardcodes hlTotalAccountValue to 0 and shows hlUnrealizedPnl instead of the real HL account value. Options: compute from hl_positions, add column to leaderboard_mv, or fetch from HL API
tokenSymbol column drop candidate: No code path writes trades.tokenSymbol anymore (all reads go through tokens.symbol via JOIN). 18+ files still reference it directly -- migrate those reads, then drop the column
tokenAddress for HL trades FK concern: packages/hyperliquid/src/verification.ts sets tokenAddress: fill.coin (e.g., "BTC"), which is a string, not a real mint address. Since tokenAddress has a FK to tokens.mint, this only works if the indexer or HL sync creates matching token rows -- otherwise FK violations will occur in production
