📝 WalkthroughWalkthroughThis change adds crypto payment domain contracts, Prisma persistence models, database constraints, an event-driven payment state machine, and migration, integration, and unit tests. Existing purchase intents default to the ChangesCrypto execution model
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR adds crypto payment models and lifecycle enforcement while preserving existing card intents. It is not merge-ready until the database rejects inactive wallet or permission scopes and unresolved reconciliation cannot be marked complete; otherwise invalid payment records, blocked intent slots, or misleading payment status can result. Test cleanup and atomic-amount validation/precision also need explicit owner follow-up. Sequence Diagram(s)sequenceDiagram

P1 — the transition table is written three times, in two languages, with nothing asserting they agree. The same rule about which crypto payment states follow which is encoded in:
I diffed 1 against 2 edge by edge and they match exactly today, and 3's seven states are exactly the seven with outgoing edges — so this is not a bug report, it is a drift risk with three specific locations. The failure modes are asymmetric and none of them is loud: adding a state to the TS map but not the trigger surfaces as The defence-in-depth is the right call — the trigger comment ("Keep direct SQL and future workers inside the reviewed lifecycle") is exactly the right reason to duplicate. It just needs a test that reads all three and asserts equality, so the duplication stays deliberate rather than becoming two rules. An integration test can pull the trigger's function body from P1 — confirm intended: Neither the TS map nor the trigger has an edge out of What makes that safe is the confirmation depth — but that value is P1 — if (!payment) throw new Error(`Crypto payment not found: ${paymentId}`);

In `@docs/architecture/002-crypto-domain-model.md`:
- Around line 34-36: Document the required decimal precision for atomic amount
arithmetic and update the database initialization in the Prisma client setup to
call Prisma.Decimal.set with precision 100 before constructing PrismaClient.
Ensure this configuration applies to Decimal instances returned by Prisma
queries, while preserving the existing initialization flow.
In `@prisma/migrations/20260819070000_add_crypto_execution_models/migration.sql`:
- Around line 282-300: Update the crypto payment scope trigger to require an
active, currently valid CryptoSpendPermission and an active CryptoWalletAccount
before accepting the insert, while preserving the existing field-matching and
allowance checks. Use the permission’s status/validity fields and the wallet
status in the trigger’s validation, and add integration coverage in the
cryptoPaymentConstraints tests for revoked permissions and suspended wallets;
document the existing per-payment allowance limitation without expanding scope
to period accounting.
In `@prisma/schema.prisma`:
- Around line 205-239: Document the database-only invariants directly above the
CryptoPayment model, following the existing VirtualCard comment convention: note
the CHECK constraints, CryptoPayment_one_active_per_intent_key partial unique
index, immutable-terms trigger, status-transition trigger, and insert-time scope
trigger. Do not alter the model fields or relations.
In `@src/contracts/crypto.ts`:
- Around line 35-42: Define a Zod schema alongside CryptoTokenAmount enforcing
the specified tokenAddress, displayCurrency, assetSymbol, tokenDecimals, and
positive amountAtomic constraints while allowing nullable displayAmount; derive
CryptoTokenAmount from that schema instead of maintaining a separate interface.
In `@src/contracts/index.ts`:
- Line 12: Remove the duplicate PaymentRail re-export from the contracts barrel
export, keeping its export in the single intended contract module and leaving
the other contract exports unchanged.
In `@src/crypto/paymentStateMachine.ts`:
- Around line 110-125: Update the transition timestamp logic around the status
switch so reconciledAt is written only for statuses that resolve reconciliation,
not by the default branch. Ensure the RECONCILING to SUBMISSION_UNKNOWN path
leaves reconciledAt unset, and add a unit case in the payment state machine
tests covering RECONCILING plus SUBMISSION_AMBIGUOUS.
In `@tests/integration/db/cryptoPaymentConstraints.test.ts`:
- Around line 120-198: Add integration coverage in the “crypto payment database
invariants” suite for REVOKED and EXPIRED spend permissions, permissions outside
their validity window, and SUSPENDED wallets, asserting crypto payment creation
is rejected. Update the database enforcement trigger used by createPayment so
these invalid permission and wallet states are rejected consistently, while
preserving the existing rail-scope and allowance checks.
- Around line 111-118: Guard the cleanup operations in afterAll with runtime
checks before using userId, walletAccountId, or spendPermissionId in Prisma
where clauses. Only run each ID-dependent delete when its corresponding
identifier was successfully assigned, while still disconnecting Prisma
unconditionally.
In `@tests/unit/db/contracts.test.ts`:
- Around line 68-80: Update the CryptoPaymentStatus assertion to use strict
toEqual with the complete expected enum set, including EXECUTING, SUBMITTED, and
CONFIRMING, while preserving the existing statuses and ordering/style used by
the adjacent CryptoProtocol and CryptoNetwork assertions.

Pushed The one that was actually losing money@coderabbitai — Reading is exact either way, so nothing in the existing tests could see it; any computed transfer amount was silently wrong. Scope trigger@coderabbitai — accepts revoked, expired, and invalid permissions. Fixed. The trigger now also reads the permission's @chatgpt-codex-connector — asset symbol. Fixed in the same condition; a payment can no longer label the asset differently from the permission that will be spent. @chatgpt-codex-connector — address normalization. Fixed at the write boundary rather than the index: Index and lifecycle@chatgpt-codex-connector — another payment after success. Not intended; success should close the intent. The predicate is now every status except the four that moved no funds ( P1 — the transition table written three times.

The Coinbase work lands as a stack: #202, #203, and #204 are all based on feat/coinbase-foundation rather than on main. The pull_request trigger filtered on branches: [main], so none of those three ran lint, type check, unit tests, integration tests, or CodeQL -- the only green checks on them were Dependabot and CodeRabbit, and the gap is invisible because a PR with no matching workflow looks the same as one with nothing to run. Dropping the filter costs nothing: a pull_request event still only fires for an open PR, and same-repo branches keep access to the Stripe secret the integration job needs.
Prisma.Decimal is decimal.js, whose default precision is 20 significant digits. Atomic amounts are DECIMAL(78,0), so arithmetic on a realistic uint256 rounded silently: 123456789012345678901234567890123456789012345678901234567890 plus 1 returned ...900000000000000000000000000000000000000000. Reading is exact either way, but any computed transfer amount was wrong with no error raised. src/db/client.ts now raises the bound before constructing the client. The insert-time scope trigger read the permission's addresses, decimals, and allowance but never its status, validity window, or asset symbol, and never the wallet's status. A payment could therefore be created against a revoked, expired, or not-yet-active permission, or on a suspended wallet, take the one-active-per-intent slot, and only fail onchain much later. It could also label the asset differently from the permission that would actually be spent, which breaks the immutable terms the customer approved. The active-payment index listed the seven nonterminal states, so SUCCEEDED dropped out of it and a second payment could be inserted for an intent that was already paid, under a fresh digest and execution key. One intent is one purchase: the predicate is now every status except the four that moved no funds, so success permanently closes the intent while failed, denied, and expired requests stay replaceable. EVM addresses are case-insensitive; PostgreSQL TEXT indexes are not. The wallet uniqueness indexes would have admitted the same address twice in two casings, potentially under different owners. Triggers canonicalize addresses and hashes to lowercase on write, ahead of the CHECK constraints, which now admit only lowercase. Leaving RECONCILING via SUBMISSION_AMBIGUOUS resolves nothing, but it stamped reconciledAt anyway; the next reconciliation attempt then wrote a newer reconciliationStartedAt behind it, so the row claimed to be reconciled while still ambiguous. reconciledAt is now written only on the edges that resolve. A caller payload naming paymentId, previousStatus, or newStatus overwrote the authoritative values in the audit event. Caller metadata is nested under a "detail" key instead. Missing payments now raise CryptoPaymentNotFoundError rather than a bare Error, so callers can map it to a 404 without string matching. Adds cryptoTransitionParity.test.ts, which reads the trigger body from pg_get_functiondef and the index predicate from pg_indexes and asserts both still agree with TRANSITIONS -- the lifecycle is written in three places and drifts silently. Adds a Zod schema for CryptoTokenAmount mirroring the CHECK constraints, records the database-only invariants in schema.prisma, drops the duplicate PaymentRail re-export, guards the integration cleanup against undefined ids that Prisma would read as 'no filter', and pins the enum sets exactly.
