Phase 2: Security & Idempotency Implementation (Waves 1-2)

[TechHypeXP]

Summary

Comprehensive Phase 2 implementation delivering security hardening, webhook idempotency prevention, and auth session persistence. All changes validated with strict TypeScript compliance.

🔒 Security & Idempotency (Wave 2)

Wave 2.1: Webhook Idempotency Prevention

• New: src/lib/webhooks/idempotencyManager.ts - Redis-based webhook deduplication
  • checkIdempotency() - detect duplicate webhooks with 7-day TTL
  • markWebhookProcessed() - store processing results for replay detection
  • extractWebhookId() - provider-specific header extraction (Shopify, UpPromote, Stripe)
  • getWebhookBodyHash() - SHA-256 hashing for replay detection
• Updated: All 4 webhook routes (Shopify, UpPromote, Orders, Process-Order)
  • Added idempotency checks before processing
  • Return 200 OK for duplicates (idempotent HTTP pattern)
  • Improved error handling with separate success/failure tracking
• Security: Added timingSafeEqual() for constant-time signature verification

Wave 2.2: Referral Conversion Idempotency

• Updated: src/lib/referrals.ts - processOrderCommission()
  • Check if commission already exists for (referrer_id, order_id)
  • Return existing commission if already processed
  • Prevents duplicate commissions from webhook retries
• Database: Unique constraint added via migration

Wave 2.3: Auth Session Persistence

• Updated: Auth routes (login, signup, logout, refresh)
  • Set httpOnly cookies for access_token and refresh_token
  • Secure flag enabled in production
  • SameSite=Lax for CSRF protection
  • Proper cookie lifecycle (maxAge matches token expiry)
• Updated: src/lib/auth.ts - Migrated from Proxy pattern to explicit getSupabase() factory

🗄️ Admin Settings Persistence (Wave 1.3)

Settings File Mutation

• New: src/lib/admin/settingsMutator.ts - Safe TypeScript file mutation
  • mutateSettings() - safely update settings with validation
  • Prevents dangerous patterns (imports, eval, process.env)
  • Automatic backups before mutations
  • Proper TypeScript value serialization
• Updated: Admin settings route - Now actually mutates settings.ts
  • Reads updated file → commits to git → triggers Vercel deployment

Git Workflow Integration

• Created: src/lib/admin/gitManager.ts - Full git workflow automation
  • Write → stage → commit → push with exponential backoff retry (2s, 4s, 8s, 16s)
  • Commit metadata: section, field, admin email, timestamp

Vercel Deployment

• Created: src/lib/admin/vercelManager.ts - Vercel API integration
  • Trigger deployments via API
  • Poll status every 5 seconds
  • 300-second timeout with error handling

Audit Logging

• Updated: src/lib/admin/settingsManager.ts - Enhanced audit trail
  • Track deploymentId, deploymentStatus, deployedAt
  • Deployment progression: pending → building → ready/failed
  • Find and update audit entries with deployment info

📊 Database Schema Updates (Migration 005)

Deployment Tracking

• audit_log.deployment_id, deployment_status, deployed_at columns
• Indexes for deployment query optimization

Idempotency Tracking

• Unique constraint: (referrer_id, order_id) on commissions table
• Webhook tracking columns: webhook_id, idempotency_key, webhook_processed_at
• Webhook_id tracking on referrals and orders tables

Indexes

• idx_audit_log_deployment_id, idx_audit_log_deployment_status
• idx_commissions_order_id, idx_commissions_webhook_id, idx_commissions_idempotency_key
• idx_referrals_webhook_id, idx_orders_referral_webhook_id

🧪 Test Plan

Webhook Idempotency

• Duplicate webhook with same ID returns 200 with previous result
• Different webhook IDs process independently
• Signature verification rejects invalid signatures
• Redis cache respects 7-day TTL

Referral Conversion

• Commission created only once per order+referrer
• Concurrent requests for same order create single commission
• Different referrers can create commissions for same order

Session Persistence

• Login sets both access and refresh token cookies
• Cookies are httpOnly, Secure (prod), SameSite=Lax
• Refresh updates both cookies
• Logout clears both cookies
• Session persists across page reloads

Settings Mutation

• Admin can propose, approve, discard changes
• Settings.ts actually updated with new values
• Git commit created with proper metadata
• Vercel deployment triggered automatically
• Backup created before mutations

Summary by cubic

Implements secure, idempotent webhooks with full event logging, replay/export, and a real-time monitor; durable auth sessions; and settings deploys via GitHub REST (@octokit/rest) with Vercel autoship and automatic rollback on failure. Adds DI ports/adapters, DB-backed admin audit logs, a monthly commission reset using tier-accurate rates, and an admin console; tightens webhook failure handling and payout status validation.

• New Features

  • Automatic rollback of approved settings commits via GitHub API when Vercel deploy fails or times out; audit entries updated with rollback details.
  • Admin auth fallback restores sessions from sb-access-token/sb-refresh-token cookies when no Bearer token is provided; centralized withAdminAuth wrapper.

• Bug Fixes

  • Timing-safe webhook signature verification for UpPromote (HMAC timingSafeEqual); invalid signatures are rejected before idempotency.
  • Payout status validation enforces only processing/paid; unknown values default to pending.
  • Sanitized error logging in admin auth to prevent token fragment exposure.

^{Written for commit 790e59a. Summary will update on new commits.}

src/app/api/auth/refresh/route.ts (1)

7-17: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Refresh endpoint cannot read token from httpOnly cookie — refresh flow is broken after this PR.

The endpoint reads refreshToken from request.json() (line 7), but this PR sets the refresh token as an httpOnly cookie in both the signup and refresh routes. Browser clients cannot read httpOnly cookies via JavaScript to send them in the request body. This creates a broken flow:

1. Signup path: signup/route.ts sets sb-refresh-token as httpOnly but doesn't return it in the response body — the client has no way to call this refresh endpoint.
2. Token rotation: If Supabase rotates the refresh token, the new token is set only in the httpOnly cookie (line 54-63) and is not returned in the response body (lines 33-41) — subsequent refresh calls fail.

The endpoint should read the refresh token from the cookie as a fallback.

🔧 Proposed fix: read refresh token from cookie as fallback

 export async function POST(request: NextRequest) {
   try {
-    const { refreshToken } = await request.json();
+    const body = await request.json().catch(() => ({}));
+    const refreshToken = body.refreshToken || request.cookies.get('sb-refresh-token')?.value;

src/app/api/auth/reset-password/route.ts (1)

5-21: 🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Missing rate limiting on password reset endpoint

The endpoint accepts an email and triggers a password reset email with no rate limiting. An attacker could spam this endpoint to flood a victim's inbox with reset emails or enumerate valid email addresses based on response timing. Consider adding per-IP or per-email rate limiting (e.g., via Redis with the existing setCached/getCached infrastructure).

Additionally, process.env.NEXT_PUBLIC_APP_URL is used directly in the redirectTo without a fallback or validation. If this env var is unset, the redirect URL becomes undefined/auth/update-password, producing a broken reset link.

🛡️ Proposed fix: add env validation and rate limiting

 export async function POST(request: NextRequest) {
   try {
     const { email } = await request.json();

     if (!email) {
       return NextResponse.json(
         { error: 'Email is required' },
         { status: 400 }

src/app/api/cart/add/route.ts (2)

60-105: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Cart data is now cache-only with no database persistence — data loss risk

The previous flow persisted cart data to the Supabase carts table. The new flow stores the cart exclusively in Redis with a 24-hour TTL. If Redis is unavailable (getCached returns null), the cart silently resets to empty. If the key expires or Redis is flushed, the cart is permanently lost. This is a data integrity regression for a shopping cart.

Consider either: (1) persisting cart state to Supabase as a fallback, or (2) documenting this as an intentional trade-off and ensuring Redis durability (AOF persistence, replication) is configured.

60-105: 🩺 Stability & Availability | 🔴 Critical | ⚡ Quick win

Race condition: concurrent add-to-cart requests can lose items

The cart is read from cache (getCached), modified in memory, then written back (setCached). Two concurrent requests for the same user will both read the same cart state, apply their changes independently, and the last write wins — silently dropping the other request's item. This is a classic TOCTOU (time-of-check to time-of-use) race.

Consider using an atomic Redis operation (e.g., WATCH/MULTI or a Lua script) or a distributed lock per cart key.

Successful Stripe transfer with failed commission update risks double payout

If updateError occurs after the Stripe transfer succeeds (line 162), the money has been sent but commission statuses remain approved. On the next payout attempt, these commissions will be included again, resulting in a double payout. The error is only logged — there is no compensation mechanism or alert.

Consider: (1) recording the transfer ID on each commission to prevent re-inclusion, or (2) failing loudly with an alert rather than silently logging.

86-111: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Make the webhook write path atomic. referrals and referral_stats are updated from earlier reads, and the duplicate guard is split across check/mark, so concurrent deliveries can both process and overwrite each other’s increments. Use DB-side increments or a transaction, and enforce uniqueness on the webhook/commission key.

Inline comments:
In `@migrations/005_deployment_tracking_and_idempotency.sql`:
- Around line 15-16: Update the index definitions idx_audit_log_deployment_id
and idx_audit_log_deployment_status to use CREATE INDEX CONCURRENTLY, and verify
the migration tooling executes this migration outside a transaction block as
required.
- Around line 20-21: Replace the invalid IF NOT EXISTS clause in the
unique_referrer_order_commission constraint alteration with an existence-checked
migration, such as a DO block querying PostgreSQL catalog metadata before
executing ALTER TABLE. Preserve the unique constraint on
public.commissions(referrer_id, order_id) and make rerunning the migration safe.

In `@migrations/006_webhook_event_logging.sql`:
- Line 259: Update the SECURITY DEFINER function declarations for
log_webhook_event and update_webhook_metrics to set an explicit search_path,
preferably pg_catalog (or an empty path if all references are fully qualified),
while preserving their existing behavior.

In `@src/app/api/admin/commissions/route.ts`:
- Around line 44-55: The stats calculation in the commissions route must derive
totalReferrers from the full commission dataset, not the paginated commissions
result, and avoid loading all commission rows into memory. Replace the in-memory
aggregation around allCommissions with a database-side aggregation function or
view returning totalCommissions, status-specific amounts, and COUNT(DISTINCT
referrer_id), then use that result to build stats while preserving the existing
response fields.
- Around line 16-20: Update the user lookup in the admin commissions route to
destructure the Supabase query’s error alongside user, and return a 500 response
when the query fails before applying the missing-user 403 path. Preserve the
existing successful lookup and unauthorized behavior.
- Around line 14-24: Update the authorization flow in the commissions route to
call verifyAdminAccess using the configured ADMIN_EMAIL_WHITELIST before
querying commissions. Reject callers who fail this admin check with the existing
forbidden response, and do not rely on the users lookup alone to establish
administrative access.

In `@src/app/api/admin/settings/route.ts`:
- Around line 23-24: Increase the route-level maxDuration export in the admin
settings route from 30 seconds to 60 seconds so the approve workflow, including
file operations, git push retries, and deployment persistence, can complete
within the timeout.
- Around line 216-217: Replace the blanket clearDraftChanges() call in the
successful deployment path with a targeted
deleteDraftChange(`${section}.${field}`) operation. Export or expose
deleteDraftChange(key: string) from settingsManager.ts, implement it to remove
only the approved draft entry, and preserve all other pending drafts.

In `@src/app/api/admin/webhooks/events/`[eventId]/replay/route.ts:
- Around line 11-25: Update the POST handler to call the established
verifyAdminAccess authentication flow before initiating the replay, returning
its standard unauthorized response when access is denied. Extract the
authenticated admin’s userId from that result and pass it to
webhookEventInspector.initiateEventReplay instead of undefined, preserving the
existing reason and replay behavior.

In `@src/app/api/admin/webhooks/events/export/route.ts`:
- Line 19: Replace the any-typed filters object in the webhook export route with
a dedicated filter interface/type describing its supported properties, and
declare filters using that type while preserving the existing filter behavior.
- Around line 11-74: Add the same admin authorization guard used by the sibling
webhook events route to the GET handler before reading filters or exporting
data. Call verifyAdminAccess and return its unauthorized response immediately
when access is denied, while preserving the existing export and error-handling
flow for authorized requests.

In `@src/app/api/admin/webhooks/events/route.ts`:
- Around line 53-54: Remove the as any casts from the getEvents call by typing
its provider and status parameters with the existing WebhookProvider and
event-status types, or an equivalent matching union. Preserve the current
filtering behavior while ensuring the arguments are type-safe.

In `@src/app/api/cart/add/route.ts`:
- Around line 53-58: Update the cart-add flow around the inventory check in the
route handler to reserve or decrement the requested quantity atomically when the
item is added, preventing concurrent requests from overselling stock. Ensure the
operation fails when the available inventory cannot cover the reservation; if
inventory is intentionally validated only at checkout, document that behavior
instead.

In `@src/app/api/commissions/payout/route.ts`:
- Around line 196-202: Update the failure-handling update in the payout route to
persist the Stripe failure message in commission_payouts alongside status:
'failed' and updated_at. Use the existing errorMessage value, matching the
table’s established error-message column naming, while preserving the current
update-error handling.

In `@src/app/api/commissions/process-order/route.ts`:
- Around line 40-50: Extract the duplicated POST processing flow into a shared
processOrderCommissionHandler, including idempotency checks, order/referral
resolution, commission processing, markWebhookProcessed calls, and error
handling; update the five affected routes to delegate to it. Verify that
process-order is included in the WebhookProvider type (or use the appropriate
supported provider value) so checkIdempotency and markWebhookProcessed remain
type-safe.
- Around line 126-137: Persist the parsed orderId before the main processing
try/catch, then reuse that outer-scope value in the catch block’s
markWebhookProcessed call. Remove the request.json() retry from the error path
so failed webhooks are recorded under the correct idempotency key even after the
request body has been consumed.

In `@src/app/api/referrals/track/route.ts`:
- Around line 55-77: Update both referral lookup branches in the referral
tracking handler to capture and inspect the Supabase query error alongside data.
Propagate or return a 500 response for errors other than the expected PGRST116
“no rows found” case, while preserving the existing “no referral found” flow for
that case.
- Around line 91-115: Update the commission insert in the referral tracking flow
to store the tier-specific rate from getTierConfig(currentTier).rate instead of
the hardcoded 0.05, while keeping calculateCommission(orderTotal, currentTier)
and the other commission fields unchanged.
- Around line 125-147: Update the referral stats logic after the status update
to recalculate the affected referrer’s total_conversions,
total_commission_earned, and volume_ytd, using the existing stats RPC if
available or equivalent inline increments; do not only update updated_at. Keep
the operation scoped to referralRecord.referrer_id so the subsequent
determineTier(totalConversions) uses current values.

In `@src/app/api/webhooks/shopify/route.ts`:
- Line 8: Guard the Shopify webhook handling before signature verification when
SHOPIFY_WEBHOOK_SECRET is unset or empty. Update verifyWebhookSignature or POST
to reject the request using the existing orders-route behavior, and ensure no
HMAC is created with an empty secret.

In `@src/app/api/webhooks/uppromote/route.ts`:
- Around line 335-357: The webhook failure path around markWebhookProcessed must
not cache failed deliveries as processed. Update the idempotency flow using
checkIdempotency and markWebhookProcessed so failed handler attempts remain
retryable—either persist only successful results or make duplicate detection
ignore failed entries—while preserving duplicate protection for successful
deliveries.
- Line 64: Update the tier calculation around determineCommissionTier to use the
affiliate’s monthly revenue value, with the appropriate monthly reset/source,
instead of stats.volume_ytd. Preserve the existing zero fallback when monthly
revenue is unavailable, and keep the configured minMonthlyRevenue tiering
behavior aligned with this input.

In `@src/components/admin/DeploymentMonitor.tsx`:
- Line 221: Update the gradient utility on the animated progress div in
DeploymentMonitor to use Tailwind v4’s bg-linear-to-r syntax instead of
bg-gradient-to-r, preserving the existing colors and animate-pulse class.
- Around line 243-247: Replace the nonfunctional hover:bg-opacity-75 utility on
the deployment status container in DeploymentMonitor with a Tailwind
v4-compatible hover alpha variant applied to the actual background color
classes, preserving the existing ready and non-ready color styling.

In `@src/components/admin/SettingsDiffViewer.tsx`:
- Line 57: Update the className on the SettingsDiffViewer spacing container to
use a ternary with complete literal Tailwind classes, selecting space-y-2 for
compact and space-y-4 otherwise, so both classes are detected by the scanner.

In `@src/components/admin/SettingsEditor.tsx`:
- Around line 224-258: The poll created by pollDeploymentStatus must be cleaned
up when the component unmounts and bounded if deployment status never resolves.
Store the active interval and its timeout in refs or register cleanup through
useEffect, ensure handleApprove retains or invokes the returned cleanup, and
clear both timers when the deployment reaches ready/failed or the timeout
expires.

In `@src/components/admin/WebhookMonitor.tsx`:
- Line 320: Update the filter labels and corresponding SelectTrigger controls in
WebhookMonitor: add matching htmlFor values to the labels at the time-range,
status, and event-type filters, and assign those same unique values as ids on
each SelectTrigger. Keep each label-control association one-to-one.
- Around line 439-448: Update the error-details control in WebhookMonitor’s
event rendering so the “Details” button has an onClick handler that displays the
full event.error_message through the component’s existing detail UI, or replace
the button with a non-interactive element if no such UI is available. Ensure the
rendered control no longer presents an action that does nothing.
- Around line 136-155: Update handleExport to include the selected timeRange in
the URLSearchParams using the same key and value format as the dashboard
filters, and revoke the object URL after triggering the download to prevent
leaks. Preserve the existing provider/status filtering and error handling.

In `@src/components/ui/alert.tsx`:
- Around line 37-45: Update the AlertDescription forwardRef generic to use
HTMLDivElement, matching the rendered div element while preserving its existing
HTML attributes, styling, and ref forwarding behavior.

In `@src/components/ui/card-extended.tsx`:
- Around line 1-69: Remove the unused duplicate card module by deleting
card-extended.tsx, since its Card, CardHeader, CardTitle, CardDescription,
CardContent, and CardFooter implementations duplicate card.tsx and have no
imports in src. Do not add a re-export unless an existing consumer requires this
module.

In `@src/components/ui/select.tsx`:
- Around line 7-18: Update the Select component’s prop handling to destructure
the caller’s onChange and merge it with onValueChange, ensuring both callbacks
run for each selection change. Keep the remaining props spread before the
explicit ref, value, className, and change-handler attributes so caller-provided
props cannot override the intended behavior.

In `@src/lib/admin/gitManager.ts`:
- Around line 62-72: Replace the blocking execSync usage in stageSettingsFile,
commitSettings, and pushChanges with promisified async execFile calls. Update
these functions and their callers, including persistSettingsChange, to await the
git operations while preserving their existing success and error result
behavior.
- Around line 84-92: Replace the shell-based execSync invocation in the git
commit flow with execFileSync, passing the git executable and commit-message
arguments separately so section, field, adminEmail, and description cannot be
interpreted by a shell. Preserve the existing commit message content and stdio
option.

In `@src/lib/admin/settingsManager.ts`:
- Around line 286-401: Replace the process-local auditLog usage in
findAuditEntryById, updateAuditEntryDeployment, and persistSettingsAndDeploy
with reads and updates against the existing public.audit_log table, preserving
deployment metadata across instances and cold starts. Ensure missing entries are
handled explicitly rather than silently dropping updates, and move draftChanges
access to a shared persistent store wherever draft state must survive requests.

In `@src/lib/admin/settingsMutator.ts`:
- Around line 130-158: Update the field-matching logic in the settings mutator
to escape or strictly whitelist request.field before using it in RegExp,
preventing metacharacters from changing matching behavior. Incorporate
request.section into the matching scope so only the requested section is
searched and replaced, preserving the existing not-found response and
replacement counting for valid fields.
- Around line 86-105: Update the dangerousPatterns validation in the settings
mutator to remove the broad /\/\// and /\/\*/ checks, allowing legitimate URLs
and comment-like string values. Preserve the remaining import, export, require,
eval, and process.env patterns and the existing validation flow.

In `@src/lib/admin/vercelManager.ts`:
- Around line 43-58: Update both triggerDeployment and getDeploymentStatus to
use AbortController-based fetch timeouts, with a longer timeout for deployment
triggering and a shorter approximately 5-second timeout for status checks. Pass
each controller’s signal to fetch and ensure the timeout is cleared after the
request completes.

In `@src/lib/db.ts`:
- Around line 45-54: Update getSupabaseAdmin so it requires
SUPABASE_SERVICE_ROLE_KEY and throws when that key is missing, rather than
falling back to supabaseKey. Preserve the existing cached-client behavior and
continue passing the validated service-role key to createClient.
- Around line 26-37: Update getSupabase and the auth read paths in auth.ts and
admin/auth.ts so server-side supabase.auth.getUser() calls use request-specific
authentication data instead of the process-wide singleton state. Pass the
request token or cookies explicitly, or create a per-request server client, and
remove or correct the inaccurate “Request-scoped” documentation while preserving
the existing client-side lazy initialization behavior.

In `@src/lib/referrals.ts`:
- Around line 341-394: Update the order webhook flow before calling
processOrderCommission to resolve the referral code or source referrer to the
corresponding users.id, then pass that resolved ID instead of ''. Ensure
referral orders without a valid referrer are handled appropriately, and keep
processOrderCommission’s referrer_id aligned with the commissions foreign-key
requirement.

In `@src/lib/webhooks/eventInspector.ts`:
- Around line 272-303: Update initiateEventReplay so it does not report a
successful replay initiation while the replay-processing TODO remains
unimplemented. At minimum, change the returned success message and status
handling to accurately indicate that no processing was queued; alternatively,
gate the operation behind the existing replay feature flag if one is available,
while preserving the replayError failure response.
- Line 31: Defer Supabase initialization in WebhookEventInspector by replacing
the eager supabase field initialization with lazy access through a getter or
method. Ensure getSupabaseAdmin() runs only when the existing webhook inspection
methods first need the client, while preserving their current Supabase usage.

In `@src/lib/webhooks/eventLog.ts`:
- Around line 58-60: Update the constructors of WebhookEventLogger and
WebhookEventInspector to stop calling getSupabaseAdmin() during construction;
initialize the Supabase admin client lazily in each class’s first method call,
while reusing the initialized client for subsequent calls.

In `@src/lib/webhooks/idempotencyManager.ts`:
- Around line 158-176: Update getIdempotencyStatus and the corresponding
idempotency cache write path to persist the webhook’s processing timestamp in
the Redis value, then parse and return that stored timestamp when the key exists
instead of generating a new timestamp during status checks. Preserve the
existing unprocessed and error fallback behavior.

In `@src/lib/webhooks/latencyTracker.ts`:
- Line 29: Rename the public API fields `slaBreachus` to `slaBreaches` and
`slaBreakedRate` to `slaBreachedRate` throughout `LatencyMetrics` and the
`getSLAReport` return type, updating all reads and writes in `getMetrics`,
`getSLAReport`, and `exportMetrics` while preserving their existing behavior.
- Around line 288-294: Update the measurements mapping in getMetrics to compute
min and max with reduce over latencies instead of spreading the array into
Math.min and Math.max. Preserve the existing count and average calculations and
the resulting minimum and maximum values.

In `@src/lib/webhooks/webhookHandler.ts`:
- Line 46: Fix the unused originalEventId flow in webhookHandler by either
assigning it when duplicate-event detection identifies the original event, or
removing originalEventId from webhookEventLogger.logEvent calls and its related
interface if duplicate tracking is not implemented. Ensure the logs no longer
always receive undefined, updating both call sites consistently.
- Around line 44-63: Use performance.now() consistently for latency calculations
in the webhook handler: replace the Date.now()-based totalLatency computations
in the duplicate-event path and the other corresponding paths with
performance.now() minus startTime. Keep Date.now() only for wall-clock
timestamps, if required by event logging, and preserve the existing SLA and
breach-detection behavior.
- Around line 96-110: Update the persistence timing block in the webhook handler
to measure the actual markWebhookProcessed call rather than getWebhookBodyHash.
Keep payloadHash computation outside this timing window, start the timer
immediately before markWebhookProcessed, and calculate persistenceMs after that
await completes.

In `@src/types/database.types.ts`:
- Around line 508-567: Regenerate the database types from the live schema so Row
properties use standard Supabase null semantics: update
referrals.Row.referral_token and commission_payouts.Row.user_id from optional
properties to required nullable properties, while preserving the corresponding
Insert and Update definitions.
- Around line 1-5: Regenerate the Supabase schema types in database.types.ts
using migrations 005/006 so webhook_events, webhook_event_metrics, and
webhook_replays are included. Preserve the generated-file format and update the
webhook table definitions so eventLog.ts and eventInspector.ts no longer require
any casts.

In `@test-results.json`:
- Around line 1-100: Add test-results.json and the test-results/ output
directory to .gitignore so generated Playwright artifacts are excluded from
version control. Update the Playwright configuration’s testDir or test matching
settings to target the actual Playwright test location, without treating Vitest
files such as src/__tests__/idempotency.test.ts as Playwright tests.

In `@tsconfig.json`:
- Around line 63-64: Remove the duplicated ".next/dev/dev/types/**/*.ts" entry
from the tsconfig include paths, retaining the existing
".next/dev/types/**/*.ts" path and avoiding any additional invalid Next.js
output directory.

In `@WEBHOOK_SYSTEM_SUMMARY.md`:
- Line 104: Correct the documented identifiers and heading in
WEBHOOK_SYSTEM_SUMMARY.md: rename every slaBreakedRate reference to
slaBreachedRate, rename slaBreachus to slaBreaches, and change the “Compliance &
Compliance” section header to “Compliance & Auditing.” Apply these edits to all
referenced code examples and the section heading.

Outside diff comments:
In `@src/app/api/auth/login/route.ts`:
- Around line 40-71: Update the login response constructed in the route’s
NextResponse.json call to remove access_token and refresh_token from session,
returning only non-secret session metadata such as expires_in and expires_at.
Keep the existing sb-access-token and sb-refresh-token httpOnly cookie
assignments unchanged.

In `@src/app/api/auth/refresh/route.ts`:
- Around line 7-17: Update the refresh handler to read the refresh token from
the `sb-refresh-token` httpOnly cookie when `request.json()` does not provide
one, while preserving body-based token support. Ensure the existing
required-token validation uses the resolved body-or-cookie value and the
rotated-token response flow remains compatible.

In `@src/app/api/auth/reset-password/route.ts`:
- Around line 5-21: Add rate limiting to the POST handler before calling
supabase.auth.resetPasswordForEmail, using the existing setCached/getCached
infrastructure with a per-IP or per-email key and an appropriate rejection
response. Validate NEXT_PUBLIC_APP_URL before constructing redirectTo, returning
a server error when it is missing or invalid instead of producing an undefined
URL.

In `@src/app/api/cart/add/route.ts`:
- Around line 60-105: The cart update flow around getCached and setCached
currently relies exclusively on Redis, allowing carts to reset or disappear
after cache failures or expiration. Restore persistence through the Supabase
carts storage flow as the durable source or fallback, while retaining Redis for
caching; ensure cache misses do not overwrite existing persisted cart data with
an empty cart.
- Around line 60-105: Replace the non-atomic getCached/modify/setCached sequence
in the cart update flow with an atomic Redis transaction or Lua script keyed by
cartCacheKey, or protect it with a distributed per-cart lock. Ensure concurrent
requests for the same user serialize their updates so neither item addition is
lost, while preserving the existing quantity aggregation and subtotal, tax, and
total calculations.

In `@src/app/api/commissions/payout/route.ts`:
- Around line 175-182: Handle updateError after the successful Stripe transfer
in the payout flow instead of only logging it: fail loudly through the existing
alert/error-reporting mechanism and ensure the affected commissions cannot be
silently retried for another payout. Update the logic around the commissions
status update and the preceding Stripe transfer handling, preserving the normal
paid-status path when the update succeeds.
- Line 11: Validate that STRIPE_SECRET_KEY is present before the Stripe client
construction in the route module, and fail immediately with a clear
configuration error when it is missing; only pass a validated non-empty key to
new Stripe.

In `@src/app/api/commissions/payouts/route.ts`:
- Around line 147-177: Update the payout flow in the route handler around the
payout insert and commission approval so both operations execute atomically
through a transaction or Supabase RPC, rolling back payout creation if
commission approval fails or conflicts. Persist the payout association on the
approved commission records using the schema’s payout-link field, validate and
propagate the approval result, and ensure concurrent requests cannot approve the
same pending commissions.

In `@src/app/api/products/route.ts`:
- Around line 72-73: Escape or validate the user-provided search value before
interpolation in the query-building branch of the products route, covering
PostgREST filter syntax characters such as commas, parentheses, and periods,
plus LIKE wildcards percent and underscore. Preserve the intended
name/description matching while ensuring search input cannot alter filter logic
or broaden the pattern.

In `@src/app/api/referrals/route.ts`:
- Around line 43-55: Replace the explicit any annotations in the referrals
filter and commissions reduce callbacks with the generated Database row types
from "`@/types/database.types`", using the referrals and commissions table Row
types respectively. Preserve the existing status and amount aggregation behavior
while ensuring callback fields are checked against the synchronized schema.

In `@src/app/api/webhooks/orders/route.ts`:
- Around line 88-94: Update the referral handling around processOrderCommission
to resolve the referrerId from referralToken before invoking it. Replace the
empty first argument with the resolved referrerId, while preserving the existing
orderId and parsed total_price arguments and referralToken guard.

In `@src/app/api/webhooks/uppromote/route.ts`:
- Around line 86-111: Make the webhook processing path atomic: replace the
read-modify-write updates in the referral conversion and stats flow with
database-side increments or a transaction, and combine the duplicate check/mark
into the same atomic operation. Enforce a unique constraint using the
webhook/commission key so concurrent deliveries cannot process the same
conversion more than once, while preserving the existing referral and stats
updates.

In `@src/lib/admin/auth.ts`:
- Around line 41-71: Update verifyAdminAccess to use the provided request’s
sb-access-token cookie when resolving the authenticated user, rather than
relying solely on the shared getSupabase() client. Pass the cookie-derived token
to supabase.auth.getUser(...) or create an equivalent request-scoped client,
while preserving the existing unauthenticated and error-result handling.

In `@src/lib/referrals.ts`:
- Around line 503-524: Update updateReferralStats to invoke the existing
referral-statistics recalculation logic when a referral_stats row already
exists, so conversions, commission totals, volume, and tier data are refreshed;
retain the current zero-filled insert path only when no row is found.

Unchecked error from user query yields misleading 403.

totalReferrers computed from paginated data instead of full dataset.

Line 55 uses commissions (the paginated result, max 20 rows) while all other stats correctly use allCommissions. This means totalReferrers only counts unique referrers on the current page, not the true total.

Additionally, fetching all commission records into memory (lines 44-46) to compute stats will not scale. Use SQL aggregation queries instead.

🐛 Proposed fix: use allCommissions for totalReferrers

-      totalReferrers: commissions ? new Set(commissions.map((c: CommissionRecord) => c.referrer_id)).size : 0,

Non-standard ?: in Row types changes null semantics.

referral_token?: string (line 514) in the Row type means the property may not exist (string | undefined), whereas standard Supabase generation uses referral_token: string | null (property exists, value may be null). This affects downstream null checks — === null won't guard against undefined. The same pattern appears in commission_payouts.Row for user_id (line 674). Regenerate types from the live schema to fix.

Extract shared time-range logic to avoid duplication and handle unexpected values.

The switch (lines 49–62) and the ternary chain (line 77) both encode the same time-range-to-hours mapping. Adding a new range requires updating both.

Invalid input is silently coerced instead of surfacing a validation error.

• For type === 'number': parseFloat(input) || 0 — if the admin mistypes a numeric field, it silently becomes 0 and gets proposed as the new value with no warning.
• For type === 'array' | 'object': on JSON.parse failure, it falls back to returning the raw input string — silently changing the value's type from object/array to string without any indication to the user.

Given this feeds admin-controlled payment/commission/logistics config that gets committed and deployed, a silent bad value (e.g. 0 for a fee percentage, or a stringified object) could ship to production unnoticed.

Non-atomic read-then-write on referral_stats counters — concurrent webhook deliveries can lose updates.

handleOrderAttributed reads referral_stats twice (lines 61-65 as stats, then again 108-113 as currentStats) and independently recomputes the "reset monthly volume if new month" logic each time (duplicated code), then writes back total_conversions + 1, total_commission_earned + commissionAmount, volume_ytd + amount, volume_month + amount. The same pattern appears in handlePayoutProcessed for total_paid (lines 210-226). None of these are atomic: two concurrent order/payout events for the same referrer (e.g. a burst of webhook redeliveries) can both read the same baseline and each write back losing the other's increment — silently under-counting commission/volume/paid totals on financial data.

Recommend consolidating to a single read per invocation and moving the increments to an atomic DB-side operation (e.g. a Postgres function/RPC doing SET x = x + $1) rather than app-level read-modify-write.

Swallowed error on post-transfer commission status update risks double payout.

After the Stripe transfer succeeds, the update that flips commissions to status: 'paid' only logs on failure (console.error) and still returns success. If this update fails, the commissions remain 'approved' and will be picked up again by the next POST /api/commissions/payout call — triggering a second Stripe transfer for the same commissions since money already moved but state wasn't persisted. At minimum this failure should be surfaced (alert/Sentry) and ideally block returning success: true, or be retried/reconciled.

redis.keys(pattern) is a blocking O(N) scan — prefer SCAN for production safety.

redis.keys() scans the entire keyspace and can block Redis for significant durations on large datasets. Additionally, deleting keys one-by-one (Lines 348-351) incurs N round-trips. Use SCAN for iteration and batch-delete with a single DEL call.

request.json() in the catch block will throw — body already consumed.

The request body is consumed at line 32 (const body = await request.json()). Calling request.json() again at line 133 will throw, and the inner catch silently swallows it. Failed webhooks are never marked as failed under the correct idempotency key. The body variable from line 32 is in scope — reuse it instead of re-parsing.

🐛 Proposed fix: reuse outer-scope body

   } catch (error) {
     console.error('Error processing order commission:', error);
     // Mark as failed
     try {
-      const body = await request.json();

     }

Note: orderId and body from the outer try scope (lines 32–33) are accessible in the catch block. If the error occurred before line 32 (e.g., secret check), orderId will be undefined — add a guard if needed.

Silently ignored query errors from referral lookup still mask database failures.

Contract tests have type mismatches with port interfaces — won't compile in strict mode.

The IIdempotencyStore port defines:

• checkIdempotency(provider, webhookId) → Promise<IdempotencyCheckResult> (2 params, returns object)
• markWebhookProcessed(provider, webhookId, result: {success, message, data?}, eventLogContext?) → Promise<boolean>

But the contract tests:

• Call checkIdempotency with 3 args (extra ttl) and expect boolean return (Lines 44, 56, 64, etc.)
• Call markWebhookProcessed with a string 'success' instead of a result object (Lines 53, 61, 73, etc.)

These will fail TypeScript strict-mode compilation.

   test('checkIdempotency returns false on first call', async () => {

Contract says failed webhooks must never be cached, but the type signature allows it.

The doc states: "Contract: Only call for successful terminal outcomes. Failed webhooks MUST NOT be cached to allow provider retries." Yet markWebhookProcessed still types status as 'success' | 'failed', and the adapter implementation (see adapters.ts) will happily cache a 'failed' entry if called that way. Consider tightening the signature to only accept 'success' (or dropping the status parameter) so the invariant is enforced by the type system rather than by convention alone.

Stripe webhook signature header event.id webhook idempotency documentation

💡 Result:

To securely and reliably handle Stripe webhooks, you must implement signature verification and idempotency as core parts of your integration [1][2]. Signature Verification Stripe includes a Stripe-Signature header with every webhook request [3][4]. This header contains a timestamp and a signature (using HMAC with SHA-256) that allows you to verify the event was generated by Stripe and not modified by a third party [5][6]. To verify: 1. Obtain your endpoint signing secret (starting with whsec_) from the Stripe Dashboard or CLI [7][4][2]. 2. Use an official Stripe library to call the verification function (e.g., stripe.webhooks.constructEvent) [7][5][2]. 3. You must provide the raw request body, the Stripe-Signature header, and your signing secret [7][2]. Note that the raw body must be used exactly as received; if your application parses the body (e.g., using JSON middleware) before verification, it will likely fail [7][1]. Webhook Idempotency Stripe may deliver the same event multiple times, such as during automatic retries after a non-2xx response [5][1][8]. To prevent duplicate processing: 1. Use the event.id field (e.g., evt_123...) from the event payload as your unique identifier for deduplication [1][8]. 2. Implement an idempotency check in your database before processing the event [1][8]. A recommended pattern is to store the event ID atomically as part of the same transaction used to fulfill the business logic [1][8]. 3. If your system finds that an event ID has already been processed, return a 2xx response immediately without re-executing the business logic [1][8]. This ensures that Stripe considers the delivery successful [1][8]. Always ensure your webhook handler is designed to handle events asynchronously, ideally by enqueuing them and returning a 200 OK as quickly as possible to prevent timeouts [1].

Returning HTTP 200 on handler failure may prevent provider retries.

The orders webhook handler returns HTTP 500 on commission processing failure (line 102-106), but this handler returns HTTP 200 with success: false. Most webhook providers only retry on non-2xx responses. The comment says "do NOT prevent retries" but returning 200 typically signals success.

Proxy creates a new client per property access — stateful operations will break.

The proxy's get trap calls getSupabase()/getSupabaseAdmin() on every property access. While query chains work (.from() returns a builder, not the proxy), stateful operations like supabase.channel('name') followed by supabase.removeChannel(channel) would operate on different client instances. This is acceptable for the migration period but should be called out in the deprecation warning.

use request cookie context instead of the fresh client returned by
getSupabase(). Update the fallback around supabase.auth.getUser() to use the
existing request-scoped server client, or explicitly provide the request’s
access token, while preserving the Bearer-token path and admin user validation.

- Around line 375-381: Update the handler error response in the Uppromote
webhook route to return HTTP 500 instead of the default 200, while preserving
the existing failure payload and error details. Keep successful webhook
responses unchanged and align the failure status with the orders webhook
behavior.
- Around line 189-190: Update the payout status mapping in the webhook handler
so only the recognized processing and paid values are persisted as their
corresponding statuses; map failed, pending, cancelled, undefined, and any other
unrecognized values to pending instead of paid. Keep payout_date populated only
when the validated status is paid.

In `@src/lib/db.ts`:
- Around line 57-61: Update the deprecation warning associated with the Supabase
proxies to explicitly state that each property access creates a new client
instance, so stateful operations such as channel creation and removal may not
work across calls. Apply this clarification to both the regular and admin proxy
warnings without changing the proxy behavior.

Remove @types/glob glob 13 already ships its own TypeScript types, so this package is redundant and can cause duplicate type resolution. Drop it unless you still need compatibility with an older glob consumer.

Read-then-write pattern for referral_stats remains a lost-update risk.

The TODO at line 115 acknowledges this. Under concurrent webhook deliveries for the same referrer, (stats.total_conversions || 0) + 1 will overwrite concurrent increments. The same pattern appears in handlePayoutProcessed (lines 198-211). Consider using a Supabase RPC/stored procedure with UPDATE ... SET total_conversions = total_conversions + 1 for atomic increments as an interim fix before the Redis Lua script.

In `@src/app/api/webhooks/uppromote/route.ts` around lines 114 - 125, The referral
statistics updates in the webhook handler and handlePayoutProcessed still use
read-then-write arithmetic, allowing concurrent deliveries to overwrite
increments. Replace both update paths with a Supabase RPC or stored procedure
that atomically increments the counters and volumes in SQL, preserving the
existing reset-timestamp behavior and referrer targeting; update the TODO to
reflect the chosen interim atomic approach.
