fix(verify): stop printing the issuer twice on co-branded credentials - #85
Conversation
Found during a browser tour of the open PRs. The public credential page rendered
Issued by Nalanda University × Nalanda University
for every program certificate, because a program run by the same organisation
that awards it stores that organisation in both `issuer` and
`metadata.coBrandPartner`, and the page concatenated them unconditionally.
Small, but it lands on the one page a sceptical employer actually reads — the
page the whole "verifiable credential" pitch rests on. Three seeded program
credentials show it today (NX7K-4MPQ-W2TR, NX9P-2KTM-R7WD, NX4B-8HLQ-Z3VG).
Fixed in code rather than in the seed: the data is legitimate — the org really
is both issuer and partner — so the presentation is what was wrong, and any
tenant that co-brands with itself would have hit this again.
`issuerLine()` is extracted as a pure helper and compares case-insensitively
after trimming, since credential metadata is hand-entered and "nalanda
university" is the same institution as "Nalanda University".
Tests: 119 (+4).

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The verification page can fail to render for credentials with malformed co-brand metadata because the new formatting logic trims the value without first confirming it is a string. This is a bounded, localized risk that is mergeable with explicit owner awareness and follow-up. Poem

`credential.metadata` is an untyped JSON column, so the
`as { coBrandPartner?: string }` cast on the verify page was a compile-time
promise only. A non-string that reached the row some other way would land on
`issuerLine`'s `.trim()` and throw — a 500 on the public credential page
instead of the issuer fallback.
`coBrandPartnerFrom()` does the narrowing where the JSON is read, so
`issuerLine` stays pure and typed. Every live row is a string today, so this
changes nothing that renders now; it closes the boundary.

The data isn't wrong — the organisation genuinely is both issuer and partner. The presentation was wrong, and patching the seed would leave any real tenant that co-brands with itself hitting the same thing.
issuerLine()is extracted as a pure helper (matchingcanGrade/canAccessTenantType/asCourseLevel) and compares case-insensitively after trimming, because credential metadata is hand-entered and "nalanda university" is the same institution as "Nalanda University".Verification
