fix(audit-v2): platform-wide post-merge hardening across 5 domains
Five-domain audit (security, routes, DB, integrations, UI/UX) ran after
the cf37d09 merge. Critical + high-impact items landed here; deferred
medium/low items indexed in docs/audit-final-deferred.md (now organised
into a "Audit-final v2" section).
Security:
- Storage proxy tokens now bind to op (`'get'` vs `'put'`). A long-lived
download URL minted by `presignDownload` for an emailed brochure can no
longer be replayed against the proxy PUT to overwrite the original
storage object. `verifyProxyToken` requires `expectedOp` and rejects
mismatches; legacy tokens missing `op` fail-closed. Regression tests
added.
- Markdown email merge values are now markdown-escaped (`[`, `]`, `(`,
`)`, `*`, `_`, `\`, backticks, braces) before substitution into the
rep-authored body. A malicious value like `[click here](https://evil)`
stored in `client.fullName` no longer survives `escapeHtml` to render
as a real `<a href>` in the outbound email. Phishing-via-merge-field
closed; regression tests added.
- Middleware now performs an Origin/Referer check on
POST/PUT/PATCH/DELETE to `/api/v1/**`. Defense-in-depth on top of
better-auth's SameSite=Lax cookie. Webhooks/public/auth/portal routes
exempt as they don't carry the session cookie.
Routes:
- Template management routes were calling `withPermission('documents',
'manage', ...)` — but `documents` doesn't have a `manage` action. The
registry has `document_templates.manage`. Every non-superadmin was
getting 403'd on the seven template endpoints. Fixed across the
/admin/templates surface.
- Custom-fields permission resource is hardcoded to `clients` regardless
of which entity (yacht/company/etc.) the values belong to. Documented
as deferred (requires per-entity routes).
DB:
- documentSends: every parent FK (client_id, interest_id, berth_id,
brochure_id, brochure_version_id) now uses ON DELETE SET NULL so the
audit trail outlasts hard-deletes. The denormalized columns
(recipient_email, document_kind, body_markdown, from_address) were
added precisely for this. Migration 0035.
- Polymorphic discriminators on yachts.current_owner_type and
invoices.billing_entity_type now have CHECK constraints — typos like
`'clients'` vs `'client'` were silently inserting unreachable rows
before. Migration 0036.
Integrations:
- Email attachment resolution (`src/lib/email/index.ts`) was importing
MinIO directly instead of `getStorageBackend()`. Filesystem-backend
deployments would have broken every email-with-attachment send. Now
routes through the pluggable abstraction per CLAUDE.md.
- Documenso DOCUMENT_OPENED webhook filter relaxed: v2 may omit
`readStatus` or send lowercase, so an event that was the SIGNAL of an
open was being silently dropped. Now treats any recipient on a
DOCUMENT_OPENED event as opened.
UI/UX:
- Expense detail used to render `receiptFileIds` as opaque UUID badges —
reps couldn't view the receipt they uploaded. Now renders an image
thumbnail (via `/api/v1/files/[id]/preview`) plus a Download link for
PDFs. Closed the "where's my receipt?" loop in the expense flow.
- Expense detail Edit + Archive buttons now `<PermissionGate>` and the
archive mutation surfaces success/error toasts instead of silent 403s.
- Brochures admin: setDefault/archive/create mutations now have onError
toasts (only onSuccess existed before).
- Removed broken bulk-upload link in scan/page (route doesn't exist;
used a raw `<a>` triggering a full reload to a 404).
Test status: 1168/1168 vitest passing. tsc clean.

-- Audit-final v2 fix: polymorphic discriminator columns are currently free-text
|
|
|
|
|
-- and a typo in service code (e.g. `'clients'` vs `'client'`) inserts silently
|
|
|
|
|
-- and the row becomes unreachable through every read path that uses the
|
|
|
|
|
-- resolver service. Add CHECK constraints on the two most load-bearing
|
|
|
|
|
-- discriminators to surface drift at the DB level.
