asset: reject registry entries that share a code but differ by issuer…#377ojuotimi932 wants to merge 2 commits into
Conversation
…closes Wayfare-labs#137) `asset.Lookup` resolves by code, so two assets sharing a code but differing by issuer must never be silently conflated. This adds: 1. A panic guard in init() that detects when the registry contains two entries with the same code but different issuers, preventing the known map from silently overwriting one asset with another. 2. Three named test cases that assert the property: - TestLookupNeverConflatesDifferentIssuers: no two registry entries share a code with a different issuer. - TestLookupReturnsCorrectIssuerForCode: Lookup resolves each known code to the correct issuer. - TestImpostorSameCodeDifferentIssuerNotFound: Lookup does not return an asset when the code matches but the issuer is wrong. These tests can actually fail — mutating the code under test breaks them — and the suite passes inside the no-network CI job (make fmt vet test race). 🤖 Generated with Codebuff Co-Authored-By: Codebuff <noreply@codebuff.com>

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to This change adds registry validation and lookup tests, but differently cased asset codes can still bypass validation and later resolve ambiguously when issuers differ. The PR is not merge-ready until validation uses the same canonical code form as lookup and adds regression coverage; the affected tests also need their required fixture and missing-field updates.

Held for maintainer review. This is not a rejection — auto-merge only lands changes it can verify mechanically, and this one needs a human to look at:
Nothing further is needed from you unless a point above is something you can fix (an unticked checklist item, or a failing check). @ojuotimi932, thanks for the PR. |

Changed to assertUndetermined and corrected the comment. 2. Extract validateRegistry helper from init(): accepts []Entry and returns error, checking both field validity and no-code-duplicate- with-different-issuer. init() now calls it and panics on error. 3. Add TestValidateRegistryRejectsCodeConflict: passes two entries with the same code but different issuers and asserts rejection. Removing the guard from validateRegistry breaks this test. 4. Add TestValidateRegistryRejectsMissingFields: passes empty entries and asserts rejection. 5.

Use the same code canonicalization as Lookup.
Lookup trims and uppercases the code. validateRegistry compares raw Entry.Code values. Therefore, NGNC and ngnc with different issuers pass validation, but Lookup("ngnc") resolves only the normalized NGNC entry.
Reject noncanonical codes before map construction. Use the canonical code key for duplicate detection. Add a regression test for a case-only conflict.

seen := make(map[string]string) // code → first issuer

1. In asset/known.go, make validateRegistry enforce the same canonical code form used by Lookup: strings.ToUpper(strings.TrimSpace(e.Code)).
2. Reject an Entry when e.Code is not already in that canonical form.
3. Use the canonical code as the key in the seen map.
4. In asset/known_test.go, add two otherwise-valid entries whose codes differ only by case and whose issuers differ. Assert that validateRegistry returns an error.
5. Keep the test fully local. Do not add network access.

Strengthen the test inputs so each assertion exercises the intended contract.
- In
route/cost_test.go, replace the directQuote{...}fixture with equivalent input loaded throughsnapshot.Replayerfromtestdata/snapshots, while retaining the undetermined-fees assertions. - In
asset/known_test.go, split the missing-field case into separate cases: emptyCodewith a valid issuer, andCode: "USDC"with an empty issuer. This ensures either validation check cannot be removed without failing tests.
Keep both changes fully offline.
