refactor(db): a repository and a row type for every table, with SQL named in *.sql.ts - #356
Every table the solver creates now has an explicit row type and a repository interface, and no SQL is written inline in a function. Behaviour and schema are unchanged.
This replaces the earlier asset-RFQ domain pilot on this branch (versioned CAS, pure transition functions). There is no domain layer here: business rules stay where they were, in the stores, the state machines and the orchestrators.
What changes
Named SQL. Every statement lives in a *.sql.ts beside the store that runs it: DDL, migrations, reads, writes and the guards passed to transitionWhere. Store methods only pick a statement and pass parameters. Dynamic parts (IN-list placeholders, column lists, ORDER BY options) are small named builders in the same module.
Table = object.packages/solver-app/src/ops/schemaCatalog.ts lists all 28 tables:
SolverTables maps each table to its row type;
SolverRepositories maps each to the repository that owns it;
SCHEMA_CATALOG maps each to its .sql.ts.
Missing row types were added for:
<swap>_event and offer_fill_event;
admin override, notify state and migration;
both balance checkpoints;
rebalance_transfer, rebalance_clock and rebalance_rfq;
the EVM journal and attempts.
Repositories. Each store implements an interface: SendSwapRepository, ReceiveSwapRepository, OnchainSendSwapRepository, AssetRfqSwapRepository, OfferFillRepository, EvmSendSwapRepository, EvmReceiveSwapRepository, AdminRepository, RebalanceRepository, RebalanceRfqRepository and EvmTransactionJournal.
The four BTC swap interfaces extend one SwapRepository<Row, State>.
Callers (orchestrators, corridor adapters, services.ts, worker.ts) depend on the interfaces. The concrete classes appear only where stores are opened.
Inline SQL moved out of non-store code. Two places ran SQL directly:
rebalance_rfq moved from rebalanceRoutes.ts into SqliteRebalanceRfqRepository;
the EVM durable sender moved into SqliteEvmTransactionJournal. Its statements and their order are the same.
Dead code removed. These methods had no production caller and are removed with their SQL and tests:
pageRecoverable, together with the recoveryOrderIndex shape field;
AssetRfqSwapStore.findLiveByOfferScript;
OfferFillStore.findByRfqId;
AdminStore.get/setLastAnnouncedBalance.
Comments. Comments in the DB layer went from about 23% of lines to about 6%. What remains are traps the code cannot show, such as D1 flattening newlines, the newest-first ordering on correlation ids, and amounts stored as TEXT.
Checks
test/db/schemaCatalog.test.ts fails if:
a CREATE TABLE appears that the catalogue does not list, or a table is in the wrong file;
a SQL statement appears in any source file other than a *.sql.ts. The shared pageQuery builder is exempt.
test/db/search.test.ts now reads column declarations from the .sql.ts files. Its assertion is unchanged.
No other test assertion changed. The 11 deleted tests covered the removed methods.
pnpm test: 6556/6556 pass, typecheck and prettier are clean.
Left as is
admin_notify_state no longer has a reader or a writer, but it is still created. Dropping it is a schema change and belongs in a separate PR.
RebalanceStore.list has no production caller, but the rebalance tests use it to read state.
Row types for the admin tables that had none are snake_case raw shapes. The swap rows are mapped camelCase types as before.
Summary by CodeRabbit
Refactor
Updated database access across swap, offer, rebalance, and admin operations while preserving existing workflows.
Added durable transaction and RFQ record handling.
Bug Fixes
Improved safeguards for swap refunds, transaction updates, and balance reporting.
Chores
Removed several legacy lookup, pagination, and balance-notification methods.
The pull request moves database schemas and queries into dedicated SQL modules, adds repository interfaces for stores, and updates consumers to use those interfaces. It also relocates rebalance RFQ persistence and EVM transaction-journal operations into repository implementations.
Changes
Corridor repositories
Layer / File(s)
Summary
Shared swap-store SQL and repository packages/solver-corridors/src/db/baseSwapStore*
Shared query builders now supply SQL to the base swap store, which implements a repository interface. pageRecoverable and its test are removed.
Send, receive, and on-chain swap persistence packages/solver-corridors/src/db/{swaps,receiveSwaps,onchainSwaps}*, packages/solver-corridors/src/db/onchainReceiveDrainGuard*
Schemas and queries move to SQL modules. The store methods use named statements, and their repository contracts are added or implemented.
Asset RFQ and offer-fill persistence packages/solver-corridors/src/db/{assetRfqSwaps,offerFills}*, test/db/{assetRfqSwaps,offerFills}.test.ts
SQL statements and schemas move to dedicated modules. Store repository contracts are added. findLiveByOfferScript and findByRfqId are removed with their tests.
EVM swap SQL moves into dedicated modules. The store classes implement repository interfaces, which EVM corridor readers and orchestrators now accept.
Repository consumers and schema checks packages/solver-app/src/ops/{assetOffers,corridorSet,rails,services,schemaCatalog,worker}.ts, packages/solver-corridors/src/{asset/assetRfqOrchestrator.ts,corridors/*,db/driver.ts,db/layout.ts,receive/orchestrator.ts,send/*}, packages/solver-corridors-evm/src/{corridors/evmCorridors.ts,receive/evmOrchestrator.ts,send/evmOrchestrator.ts}, test/db/{schemaCatalog,search}.test.ts
Solver consumers use repository interfaces. The schema catalog maps tables to SQL modules, and tests check schema declarations and SQL placement.
Admin database
Layer / File(s)
Summary
Admin schema and store operations packages/solver-app/src/admin/db.sql.ts, packages/solver-app/src/admin/db.ts, test/admin/notifyState.test.ts
Admin schema, index, and column migrations move to db.sql.ts. AdminStore uses named statements and implements the new AdminRepository contract. The last-announced-balance methods and tests are removed.
Revert planning accepts AdminRepository, and market-pair reads use the named SQL query.
Rebalance persistence
Layer / File(s)
Summary
Transfer schema and repository operations packages/solver-app/src/ops/rebalanceStore.sql.ts, packages/solver-app/src/ops/rebalanceStore.ts, packages/solver-app/src/ops/rebalance.ts
Transfer and clock SQL moves into a statement module. RebalanceStore uses the statements for persistence and queries and exposes RebalanceRepository.
RFQ repository and route integration packages/solver-app/src/ops/rebalanceStore.sql.ts, packages/solver-app/src/ops/rebalanceStore.ts, packages/solver-app/src/ops/rebalanceRoutes.ts
SQLite RFQ storage adds JSON normalization and filtered cursor pagination. The route uses SqliteRebalanceRfqRepository instead of its local implementation.
The sender uses the journal abstraction for persistence and queries across preparation, submission, reconciliation, replacement, replay, and authorization.
This refactor moves database statements into dedicated files and adds repository interfaces without changing behavior. No merge-blocking issue was found. One optional cleanup remains: trim the comment block in the new admin SQL file.

Explanation
The title names the main change: a repository interface and row type for each database table, with SQL moved into named *.sql.ts files. The raw summary and PR objectives confirm this is the primary refactor across the solver packages. The title is specific, uses a conventional commit prefix, and is 85 characters long, which is acceptable.
