fix(email): unbreak tenant template writes, vanishing Save header, preview images - #264

…eview images
Three defects from lekkerweed's feedback, plus one sibling found on the way:
- Tenant-scope $extends wrapped update/delete wheres of the null-access
models (email_templates, email_event_mappings) in AND/OR - an invalid
WhereUniqueInput under Prisma 6, so every tenant email-template save,
delete and enable/disable toggle threw PrismaClientValidationError -> 500.
Writes are now always strictly scoped ({...where, tenantId}); the OR-null
widening is reads-only, which also means a tenant write can no longer
touch a shared system row. Regression-tested at the exported helpers -
the route tests mock @/lib/db wholesale, so the extension never runs there.
- EmailEditor/CampaignEditor hardcoded h-[calc(100vh-100px)], overshooting
their overflow-hidden hosts by ~120px; caret-reveal scrolling on the first
edit pushed the header card - Save button included - out of the clip box
with no way to scroll back. Both editors are h-full now, and the two
super-admin hosts get the same sized flex-1 overflow-hidden wrapper the
tenant pages already had.
- The preview pane's srcdoc iframe inherits the admin page's CSP, whose
img-src carries no tenant domains - so images the pipeline absolutised
against the tenant's own host rendered broken in preview while being
perfectly fetchable from a real inbox. Both preview routes now pass
req.nextUrl.origin as baseUrlOverride, resolving preview assets (uploads
and the shell logo) same-origin with the admin page. Stored and mailed
HTML keeps the tenant host.
📝 WalkthroughWalkthroughEmail previews now resolve assets against the request origin. Admin email editors now fit bounded flex layouts. Tenant-scoped Prisma writes use strict predicates, while reads retain nullable shared-row access. ChangesEmail preview and editor layout
Tenant scope enforcement
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to Tenant-scoped template writes can still use an unscoped upsert match, allowing one tenant to update another tenant’s matching record. This creates a cross-tenant data-modification risk that should be fixed before merging. Sequence Diagram(s)sequenceDiagram

logic so that after tenant ID injection, upsert.where is passed through
applyTenantWriteScope with the bound tenantId while remaining a top-level
selector. Add an extension-level regression test covering an upsert that matches
an existing record and enters the update branch.

Prisma 6.7.0 upsert WhereUniqueInput compound unique additional non-unique fields extendedWhereUnique
💡 Result:
In Prisma 6.7.0, the extendedWhereUnique feature is no longer a Preview feature; it has been promoted to General Availability [1]. This functionality was originally introduced in version 4.5.0 [2] to allow developers to include additional non-unique fields in the where filter of queries that target unique records—such as findUnique, update, delete, and upsert—provided that at least one unique field is also specified [3][2]. Key details regarding your query: Compound Unique Constraints: You can use compound IDs or compound unique constraints within the where filter of an upsert operation [4][5]. When using these, you must provide the values for all fields that make up the unique constraint [4][5]. ExtendedWhereUnique: Because this feature is now part of the stable Prisma Client API, you do not need to enable any preview feature flags in your schema.prisma file to use it [1]. By allowing non-unique fields alongside unique fields in the where clause, it enables more precise targeting for operations like upsert [2]. For example, if you have a model with a unique id, you can perform an upsert using both that id and an additional non-unique status field: await prisma.user.upsert({ where: { id: 1, status: 'ACTIVE' // This non-unique field is now supported }, update: { name: 'New Name' }, create: { id: 1, name: 'New Name', status: 'ACTIVE' } }); Ensure that the fields used to identify the record in the where clause are defined as part of a @unique or @id constraint in your schema; otherwise, Prisma will raise a validation error because it cannot guarantee a single unique record match [6][7].

Summary
Root-cause fixes for the lekkerweed feedback (template editor can't save, uploaded images broken in Preview, copied templates can't be deleted), plus one sibling defect found on the way. Full diagnosis was done against live prod +
origin/main.1. Every tenant email-template save / delete / toggle 500'd (P1)
The tenant-scope
$extendsinlib/db.tswrappedupdate/deletewheres of the null-access models (email_templates,email_event_mappings) in{ AND: [where, { OR: [{tenantId}, {tenantId: null}] }] }. Those operations take aWhereUniqueInput, which Prisma 6 generates asAtLeast<{...}, "id">— the unique field must sit at the top level — so the wrap was aPrismaClientValidationErroron every call. Broken since #230; unnoticed because super-admin routes bind a null context (unscoped) and the route tests mock@/lib/dbwholesale, so the extension never runs in them.Fix: writes (
update/delete/updateMany/deleteMany) are now always strictly scoped viaapplyTenantWriteScope({...where, tenantId}); the OR-null widening is reads-only. Also a policy tightening: a tenant write can no longer touch a shared system row.Unbreaks: template save (PUT), delete, enable/disable eye-toggle, and the event-mapper revert flow (
email-mappingsDELETE).2. Save Template button disappeared on first edit
EmailEditor/CampaignEditorhardcodedh-[calc(100vh-100px)]inside hosts that give them ~100vh-220pxwithoverflow-hidden— caret-reveal scrolling on the first keystroke scrolled the clipped container (programmatically scrollable even atoverflow:hidden), pushing the header card — Save button included — out of view with no way to scroll back. Both modes, both editors.Fix: both editors are
h-full min-h-0; the two super-admin host pages get the same sizedflex-1 overflow-hiddenwrapper the tenant pages already had.3. Uploaded images broken in Preview (fine in real emails)
The pipeline absolutises image srcs against the tenant's domain; the preview pane's
srcDociframe inherits the admin page's CSP, whoseimg-srccarries no tenant hosts → browser blocks exactly the URLs a real inbox loads happily (verified live: the same/api/public/images/...route serves lekkerweed's homepage og:image).Fix: both preview routes pass
req.nextUrl.originasbaseUrlOverride, threaded shell → pipeline → content resolver → preview, so preview assets (uploads and the shell logo) resolve same-origin with the admin page. Stored/mailed HTML keeps the tenant host — asserted both ways in tests.Test plan
tests/unit/tenant-scope-write-scoping.test.ts— pins theWhereUniqueInputshape invariant for write scoping (no AND/OR wrap, no null widening, bound tenant wins) and the unchanged read widening.tests/unit/email-preview.test.ts— two new cases: override absolutises an uploaded image to the admin origin; no override keeps the tenant domain (save-path shape).lib/db.tsis the tenant-isolation hot path — please let CI go green before merging.Post-deploy follow-up
Failed delete attempts already stripped event mappings before the 500 (the DELETE route unmaps first) — check lekkerweed's
email_event_mappingsfor events silently reverted to system default.The GSC/SEO half of the feedback needs no code: the verification tag has been live in the homepage
<head>since the SEO Supercharge deploy — the user just needs to retry verification in Search Console.Summary by CodeRabbit
