+# Repair Ponder Indexer
+
+Indexes FWSS repair inventory state for datasets, pieces, and storage providers.
+
+The shared Drizzle schema used by downstream consumers lives in `packages/repair-db`.
+Ponder owns the on-chain write schema in `apps/ponder/ponder.schema.ts`, with table names imported from
+`@filoz/repair-db`.
+
+## Tables
+
+- `providers`: current ServiceProviderRegistry state, including provider name from block-scoped `eth_call`s and the
+  PDP product `serviceURL`.
+- `data_sets`: current FWSS dataset state. `pdp_end_epoch != 0` means PDP payment termination has started.
+- `pieces`: current piece inventory keyed by `(data_set_id, piece_id)`, with a secondary CID index for finding alternate
+  providers.
+
+## Commands
+
+```sh
+pnpm --filter @filoz/repair-ponder codegen:mainnet
+pnpm --filter @filoz/repair-ponder codegen:calibnet
+pnpm --filter @filoz/repair-ponder typecheck
+pnpm --filter @filoz/repair-ponder dev:mainnet
+pnpm --filter @filoz/repair-ponder dev:calibnet
+```
+
+Set `DATABASE_URL` and `RPC_URL` to override the local defaults.
+
+Environment variables:
+
+| Variable | Values | Default | Strict mode |
+| --- | --- | --- | --- |
+| `PONDER_NETWORK` | `mainnet`, `calibnet` | `mainnet` | Required |
+| `DATABASE_URL` | PostgreSQL connection string | `postgres://ponder:ponder@localhost:17825/ponder` | Required |
+| `RPC_URL` | Filecoin JSON-RPC URL | `http://localhost:1234/rpc/v1` | Required |
+| `PONDER_STRICT_ENV` | `true`, `1` | unset | Enables strict mode |
+
+Set `PONDER_STRICT_ENV=true` to require `PONDER_NETWORK`, `DATABASE_URL`, and `RPC_URL`, which is recommended for
+deployments.
+
+## Networks
+
+| Network | Goldsky slug | FWSS address | PDPVerifier address | Start block |
+| --- | --- | --- | --- | --- |
+| Filecoin mainnet | `filecoin` | `0x8408502033C418E1bbC97cE9ac48E5528F371A9f` | `0xBADd0B92C1c71d02E7d520f64c0876538fa2557F` | `5459607` |
+| Filecoin calibration | `filecoin-testnet` | `0x02925630df557F957f70E112bA06e50965417CA0` | `0x85e366Cf9DD2c0aE37E963d9556F5f4718d6417C` | `3141266` |
+
+Start blocks are 10 blocks before FWSS proxy creation. Mainnet FWSS was created at block `5459617`; calibration FWSS was created at block `3141276`.
