Security audit fixes (see SECURITY_AUDIT.md):
- lib/tiers.ts: checkAndIncrementTierLimit's recipe/storage branches did a
live count/sum check with no lock tying it to the later write, so two
concurrent requests near the cap could both pass and both write past the
limit. Added checkTierLimitInTransaction — holds a per-user Postgres
advisory lock for the duration of the caller's transaction, so the check
and the write are atomic together. Applied to every recipe/storage write
path (recipes create/update, fork, rate, avatar, and 7 AI recipe-creation
routes).
- Adversarial re-verification of that fix caught a bigger gap in the same
area: four AI routes (photo import, idea generation, batch-cook,
translate-to-new-draft) had no recipe-limit check at all. Fixed.
- Added missing per-user rate limits to 5 AI endpoints (adapt, drinks,
pairings, translate, variations) that had none, unlike their siblings.
- search page now checks for a session server-side, matching every other
page under (app)/ — defense in depth; the underlying API was already
public by design and proxy.ts already blocked unauthenticated requests.
- admin/settings route now uses the shared requireAdmin instead of a local
duplicate.
- Documented two admin support-ticket endpoints missing from the OpenAPI
spec; verified full route/OpenAPI parity otherwise.
- Bumped drizzle-orm to fix a SQL-identifier-escaping CVE, and overrode two
transitive deps (esbuild, postcss) with known CVEs. pnpm audit is clean.

Admins can now disable specific AI features per tier from Admin > Tier
Limits — new feature_flags table (feature x tier -> enabled, defaulting
to true so adding a new gated feature never needs a backfill).
Covers recipe variations, drink pairing, and meal pairing to start.
When disabled for a user's tier, the button stays visible (with a small
lock badge) but opens an upgrade dialog instead of running; the API
route rejects the call server-side either way (requireFeatureEnabled,
re-reads tier from the DB rather than trusting the session's cache,
same rationale as checkAndIncrementTierLimit).
The upgrade dialog is informational only — no Stripe checkout exists
yet (STRIPE_PLAN.md is still just a plan) — its CTA links to /support
prefilled as an upgrade-interest suggestion.

All literal "team" tier-value references renamed to "family" across
API routes, admin UI, OpenAPI schemas, and lib/tiers.ts. The DB enum
value itself is renamed in place via ALTER TYPE ... RENAME VALUE
(migration 0044) rather than drizzle-kit's auto-generated
drop-and-recreate-the-enum migration, which would have failed against
any existing row still holding 'team' — RENAME VALUE preserves
existing data with no cast/backfill needed.
Also adds STRIPE_PLAN.md — a full Stripe billing integration plan
(Checkout+Portal, tier→Price mapping, admin billing dashboard, and a
multi-user Family-group design since Family is meant to cover several
accounts under one subscription, not one payer). Planning only, no
Stripe code yet.
v0.47.0
Widens the tier enum from free/pro to free/pro/team and every
"free" | "pro" cast that assumed exactly two tiers (~30 call sites:
every AI route's withAiQuota/checkAndIncrementTierLimit call, admin
user/invite management, upload quota checks, OpenAPI schemas). Team
sits above Pro with genuinely unlimited recipes/public-recipes (the
-1 sentinel, which Pro doesn't actually use — Pro uses large finite
numbers instead) and a higher AI-call/storage cap. Seeded via
db:seed, editable afterward from Admin > Tiers.
role (user/moderator/admin — permissions) and tier (free/pro/team —
billing limits) stay separate concepts, as they already were; this
does not touch role-based permissions.
Requires migration 0043 to run against a live DB — not applied in
this sandbox (no Docker here); run `pnpm db:migrate` then `pnpm db:seed`.
v0.44.0
Full list of the audit's confirmed findings and their fixes:
- Stored XSS via unescaped JSON-LD on the public recipe page
(app/r/[id]/page.tsx) — escape < before injecting.
- CSP allowed unsafe-eval in production — now dev-only (Next prod
never eval()s; only its HMR does).
- avatarUrl accepted any URL with no ownership check — now takes an
avatarKey issued by avatar-presign, validated server-side, same
pattern as recipe/review photos.
- No session revocation on password change/reset — both now revoke
other sessions (revokeOtherSessions: true, revokeSessionsOnPasswordReset).
- Rate-limit bypass via spoofable X-Forwarded-For — take the last
(proxy-appended) hop instead of the first (client-supplied) one,
matching the single-Traefik-hop topology.
- Webhook signing secrets stored plaintext — now AES-256-GCM
encrypted like every other secret in this app, with a legacy-
plaintext fallback for pre-existing rows (bare hex has no ":", our
ciphertext format always does).
- Better Auth's own rate limiter defaulted to in-memory storage,
ineffective across replicas — now backed by the same Redis as
lib/rate-limit.ts (secondaryStorage), with storeSessionInDatabase
explicit so session storage itself doesn't move as a side effect.
- Presigned upload URLs didn't bind the declared file size to the
actual upload, letting a client under-declare size (and quota
charge) then PUT an arbitrarily large object — switched to S3
presigned POST with a signed content-length-range condition,
enforced by the storage server itself.
- generateMetadata() on the recipe page skipped the visibility
filter the page body uses, leaking a private recipe's title via
<title> to any signed-in user with the id.
- Block/unblock had no rate limit, unlike follow/unfollow.
- AI quota was charged even when a user's own BYOK key was used
(their own credentials/billing) — added an isByok flag through
the config-resolution chain and skip the charge when set. Also
wired BYOK into generate/generate-from-idea/translate/import-url,
which never looked it up at all before.

Convert requireSession -> requireSessionOrApiKey across recipes,
collections, meal-plans, shopping-lists, pantry, feed, and ai/*
(52 routes) so API keys work end-to-end, not just for the handful of
endpoints that supported them before. Scope was explicitly confirmed
per-resource-family with the user before any file was touched.
Left session-cookie-only, deliberately: users/me*, ai-keys/*,
webhooks/*, conversations/*, notifications/*, push/subscribe, admin/*
— account/credential-adjacent surface that shouldn't widen without a
separate, explicit decision.

Full audit (bugs/UI-UX/backend/feature-gap) turned up a money-leak AI quota
bypass, webhook SSRF, and a long tail of missing pagination/auth/a11y work.
Fixes land together since HANDOFF.md tracked them as one backlog.
- AI routes charge tier quota before generating; nutrition POST is author-only
- Webhook dispatch re-validates URL per delivery (SSRF/DNS-rebinding), treats
redirects as failures; recipe.published now actually dispatches
- New indexes/unique constraints on recipes, meal-planning, comments FK cascade
- Recipe PUT/restore snapshot only inside the transaction, after validation
- Recipe DELETE cleans up S3 objects (recipe + review photos)
- Optimistic UI (favorite/star/follow/shopping-list) rolls back on failure
- Upload presign enforces file size cap + per-tier storage quota
- Route-level loading/error/not-found states across (app), admin, and root
- middleware.ts guards (app)/admin; requireAdmin checks DB role, not cached
session; rate limiting applied to both session and API-key branches,
bucketed per key; Stripe webhook dedupes by event id
- Pagination added to recipes, feed, profile, comments, pantry, admin tables
- Nav shows real avatar + profile link + dark-mode toggle; destructive actions
standardized on AlertDialog
- Unsaved-changes guard + real ingredient/step validation on recipe form;
canonical /recipes/[id] used in-app; next/image migration; aria-labels and
alt text across icon buttons, avatars, recipe photos
- packages/api-types removed (zero callers, too drifted to safely rewire);
openapi.ts and ai-keys error shape drift fixed; BYOK decrypt failures now
surface instead of silently falling back to the platform key

AI routes had no consistent error handling — a provider failure (e.g.
OpenRouter returning a degraded-model error) crashed the route as an
uncaught 500 and, worse, still charged the user's monthly aiCall
quota for a request that never succeeded.
Adds withAiQuota()/aiErrorResponse() (lib/ai/ai-error.ts) and applies
them across all 12 AI generation routes: charges the quota, runs the
AI call, refunds the credit and returns a clean user-facing message
if it throws. Frontend needs no changes — existing dialogs already
toast whatever `error` string comes back.
