fix: resolve usernames by document id, not by display name - #36
Conversation
A transfer of any username containing l, i or o failed with 'was not found'. The name list is built from the raw label property, but dpns.getUsernameByName matches on normalizedLabel, which is homograph-folded (l and i to 1, o to 0). So "testfjdksla234123.dash" listed correctly and then resolved to nothing. listOwnedUsernames now queries the DPNS domain documents directly and returns the document id alongside the display name, and transferUsername takes that id instead of looking the name up again. The round trip that could not round-trip is gone rather than patched. Discovery also no longer stops at the first identity a seed matches. One seed commonly controls several, and the first is not necessarily the one holding the name; it now scans all of them and prefers one that owns a username. The empty case is a clear callout instead of a grey line under a permanently disabled button. Verified live on testnet: registered xferlive7test.dash (normalizedLabel xfer11ve7test, which reproduces the failure on main) and transferred it — ownerId and records.identity both moved, revision 1 to 2. The mock usernames now contain an l so this class stays covered. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
📝 WalkthroughWalkthroughThe username-transfer flow now tracks DPNS document IDs and owner IDs with each username. Seed unlock evaluates multiple identities, selects an identity with owned usernames, stores other identities, and transfers the selected document directly. ChangesUsername Transfer Flow
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR correctly transfers usernames by document ID and searches across more identities, but the current flow can still miss an owning identity and can report an irreversible transfer as failed or completed before ownership is conclusively known. These bounded correctness and recovery risks should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Scanning every candidate instead of stopping at the first hit made a fixed cost of up to nine lookups per unlock -- eighteen on a full miss, since each falls back to the non-unique key index. Running them four at a time recovers the latency the full scan cost: a live testnet unlock and transfer went from 22.2s back to 15.8s. Results are folded in candidate order afterwards, so the identity reached by the earliest derivation path still wins regardless of which lookup resolved first.

Re-verified after the batching commit, with a name containing all three folded characters: Transferred successfully and confirmed on-chain: The full scan added latency (a fixed 9 lookups per unlock, 18 on a miss since each falls back to the non-unique key index). Running them four at a time brings a live unlock + transfer back to 15.8s from 22.2s, with results folded in candidate order so the earliest derivation path still wins. 🤖 Posted autonomously by Claude on behalf of pasta. |

Transferring a username containing
l,iorofailed withUsername "…" was not found. Reported frombridge.thepasta.orgontestfjdksla234123.dash, reproduced on testnet, fixed and re-verified live.Cause
The owned-names list came from
dpns.usernames(), which builds its strings from the rawlabel. The transfer then resolved that string back to a document withdpns.getUsernameByName(), which matches onnormalizedLabel— homograph-folded, sol/i→1ando→0.Those two are not the same string, so the round trip could not round-trip:
getUsernameByName(label)testfjdksla234123testfjdks1a234123pastafaucettesting1234pastafaucettest1ng1234xfertest7pastaxfertest7pastaThe last row is why this was not caught earlier: the name used in the original live test contains no
l,ioro, so it round-tripped by luck.Fix
Stop resolving names by display form at all.
listOwnedUsernamesnow queries the DPNSdomaindocuments directly and returns{username, documentId, ownerId};transferUsernametakes thedocumentIdand fetches the document. The fragile lookup is deleted rather than patched.It still queries by
records.identity—$ownerIdis not indexed on thedomaintype and Drive rejects a where clause on it. The document'sownerIdis re-checked before signing regardless.Also in this PR
Discovery no longer stops at the first identity a seed matches. One seed commonly controls several, and the first is not necessarily the one holding the name — the earlier report showed the flow locked to an identity owning nothing while the name sat on another. It now scans all of them and prefers one that owns a username, and when an identity genuinely owns none, the screen says so plainly instead of leaving a grey line under a permanently disabled Continue.
Verification
Registered
xferlive7test.dashon testnet specifically to reproduce:label=xferlive7test,normalizedLabel=xfer11ve7test,getUsernameByNameon the display form returnsundefined— this transfer fails onmain.With the fix it succeeded, confirmed on-chain independently of the UI:
ownerIdandrecords.identityboth moved to the destination,$revision1 → 2, and the name moved out of the source's list into the destination's.Regression cover: a unit test pins the label/normalizedLabel divergence for all three reported names, and the mock usernames now contain an
l, so mock runs exercise this class from here on. 111 unit tests, 8 Playwright, build and artifact check all green.🤖 Generated with Claude Code
