Final audit polish — closes the remaining LOW + MED items the previous
tiers didn't reach:
* Validation hardening: me.preferences uses .strict() + 8KB cap
instead of unbounded .passthrough(); files.uploadFile gains
magic-byte verification (jpeg/png/gif/webp/pdf/doc/xlsx); OCR scan
endpoint enforces 10MB cap + magic-byte check on receipt images;
port logoUrl + me.avatarUrl reject javascript:/data: schemes via
a shared httpUrl refinement.
* Permission gates: document-sends/{brochure,berth-pdf} now require
email.send (was withAuth-only); document-sends/{preview,list} on
email.view; ai/email-draft on email.send; documents/[id]/send
uses send_for_signing (was create); expenses/export/parent-company
flips from hard isSuperAdmin to expenses.export for parity;
admin/users/options gated on reminders.assign_others (was withAuth).
* Envelope hygiene: auth/set-password switches the third {message}
variant to errorResponse + {data: {email}}; ai/email-draft wraps
jobId in {data: {jobId}}.
* UI polish: reports-list.handleDownload surfaces failures via
toastError (was console-only).
* Ops/infra: pin pnpm@10.33.2 across all three Dockerfiles +
packageManager field in package.json; Dockerfile.worker re-orders
user creation BEFORE pnpm install so node_modules / .cache dirs
are worker-owned (fixes tesseract.js + sharp EACCES at first PDF
parse); add Redis-ping HEALTHCHECK to the worker container.
* Public health endpoint: returns full env+appUrl payload only when
the caller presents X-Intake-Secret, otherwise a minimal {status}
so generic uptime monitors still work but anonymous internet
doesn't get deployment fingerprints.
* Per-port Documenso webhook secret: new system_settings key
+ listDocumensoWebhookSecrets() helper. The webhook receiver
iterates every configured per-port secret with timing-safe
comparison + falls back to env, then forwards the resolved portId
into handleDocumentExpired so two ports sharing a documensoId
cannot cross-mutate.
Deferred (handled in dedicated follow-up PRs):
* Tier 5.1 — direct service tests for portal-auth / users /
email-accounts / document-sends / sales-email-config. MED, large
test-writing scope.
* The {ok: true} → {data: null} envelope migration across
alerts/expenses/admin-ocr-settings/storage routes. Mechanical but
needs coordinated client + test updates.
* CSP-nonce migration (drop unsafe-inline) — needs middleware-level
nonce generation that the Next 15 router has to thread through.
* Idempotency-Key header on Documenso createDocument. Requires
schema column on documents to persist the key; deferred so it
doesn't bundle a migration into this commit.
* The 16 better-auth user_id FKs — separate dedicated migration
with care (some columns are NOT NULL today and cascade decisions
matter).
* PermissionGate / Skeleton / EmptyState wraps across 5 admin lists
(auditor-H §§36–37) and the residential-clients filter bar.
Test status: 1175/1175 vitest, tsc clean.
