+# Context
+App users (landlord) can assign `tenantEmail` to a `BillingLocation`.
+
+This is a e-mail address will be used to notify the tenant when the rent is due and/or the utility bills are due.
+
+## E-mail verification
+To prevent missuse and ensure that the e-mail is correct, before an e-mail address can be used by the automatic notification system, the tenant needs to verifies that he/she accepts to receive notifications.
+
+This verification is done via a link sent to the tenant in a verification-request e-mail, which is sent to the tenant automatically when the landloard (app user) assigns this e-mail address to a BillingLocation.
+
+Sending of this verification-request e-mail is handled by a system separate from NextJS app in `web-app` workspace.
+
+### Implementation details
+Verification link points to the NextJS app in `web-app` workspace at path `/email/verify/[share-id]` (share-id is calculated using `generateShareId` from `/home/kneecola/projects/evidencija-rezija/web-app/app/lib/shareChecksum.ts`).
+
+The web page served at this path contains an text explanation and "Verify e-mail" button.
+
+The text includes the following information:
+* what the web app is about - very short into
+* why the e-mail was sent = because the landloard of the property X configured the rent (`BillingLocation.rentDueNotification`) and/or utility bills (`BillingLocation.billFwdStrategy`) to be delivered to that e-mail address
+* what will hapen if he/she clicks on the "Verify e-mail" button = they will be receiving rent due (`BillingLocation.rentDueNotification`) or utility bills due (`BillingLocation.billFwdStrategy`) notification or both - 2x a month - depending on the config set by the landloard
+* opt-out infomation (they can ignore this e-mail, but can also opt-out at any moment)
+
+If the user clicks the button "Verify e-mail" this triggers update of `BillingLocation.tenantEmailStatus`.
+
+Here's the expected stats flow:
+
+* landloard/app user assigns an an new address top  `BillingLocation` -> `BillingLocation.tenantEmailStatus` is set to `EmailStatus.Unverified`
+* a verification si sent to the entered e-mail address -> `BillingLocation.tenantEmailStatus` is set to `EmailStatus.VerificationPending`
+* tenant click the link from the verification-requets e-mail  -> `BillingLocation.tenantEmailStatus` is set to `EmailStatus.Verified`
+
+**Note:** status is updated for the `BillingLocation` inidcated by locationID (decoded from `[share-id]` param), and all subsequent matching `BillingLocation` records (matched by comparing `BillingLocation.name` and  `BillingLocation.userId`). Similar pattern is already implemented in `updateOrAddLocation` fn in `locationAction.ts` (`updateScope === "subsequent"`).
+
+## E-mail unsubscribe
+Tenant can out-out from receiving e-mail notifications at any time via an `unsubscribe` link included at the end of every mail sent to the tenant.
+
+### Implementation details
+Verification link points to the NextJS app in `web-app` workspace at path `/email/unsubscribe/[share-id]` (share-id is calculated using `generateShareId` from `/home/kneecola/projects/evidencija-rezija/web-app/app/lib/shareChecksum.ts`).

+The web page served at this path contains an text explanation and "Confirm unsubscribe" button.
+
+The text includes the following information:
+* what the web app is about - very short into
+* why are they receiveing e-mails from this page = because their landlord for property X has configured the app to deliver rent due or utility bills due notification or both to that address
+* what will hapen if they click on "Confirm unsubscribe" = they will no longer receive rent due / utility bull due reminders
+
+E-mail address's verification status is tracked via `BillingLocation.tenantEmailStatus`, which is set to `EmailStatus.Unsubscribed`.
+
+**Note:** status is updated for the `BillingLocation` inidcated by locationID (decoded from `[share-id]` param), and all subsequent matching `BillingLocation` records (matched by comparing `BillingLocation.name` and  `BillingLocation.userId`). Similar pattern is already implemented in `updateOrAddLocation` fn in `locationAction.ts` (`updateScope === "subsequent"`).
+
+## E-mail status in `LocationCard.tsx`
+
+If the e-mail is not in `EmailStatus.Verifies` state for a given location, then this will be indicated in `LocationCard.tsx` as a sibling of `total-payed-label` block (`<div className="flex ml-1">`)
+
+## E-mail status in `LocationEditForm.tsx`
+
+Current e-mail status will be indicated as a sibling of `<div id="tenantEmail-error">`.
+Use appropriate utf-8 icon for each status.
+
+# Logical Units of work
+
+Work will be split in logical units of work:
+
+* implement e-mail verification DB logic
+* implement e-mail verification page
+    * create text both in croatian (hr.json) and english (en.json)
+    * implement share-id verification (see /home/kneecola/projects/evidencija-rezija/web-app/app/[locale]/share/proof-of-payment/per-bill/[id]/route.tsx)

+# Mailgun Webhook Handler
+
+This workspace contains the Mailgun webhook handler service for processing email events related to the Evidencija Režija tenant notification system.
+
+## Purpose
+
+This service handles email verification and status updates by:
+- Detecting new tenant email addresses (EmailStatus.Unverified)
+- Sending verification emails via Mailgun
+- Updating email status to VerificationPending
+- Processing webhook events from Mailgun (bounces, complaints, etc.)
+
+## Architecture
+
+This is a separate system from the Next.js web-app that communicates via the shared MongoDB database.
+
+## Setup
+
+TBD
+
+## Environment Variables
+
+TBD

Subject: [PATCH 17/24] feat: add email verification check to unsubscribe page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Security Enhancement:
- Server-side validation of email status before allowing unsubscribe
- Only allow unsubscribing from verified emails
- Show "Action Not Allowed" message for unverified/unsubscribed emails
- Extract and validate share-id on server side
- Return 404 for invalid share-ids or missing tenant emails

Implementation:
- Convert page.tsx to async server component
- Fetch location and check tenantEmailStatus
- Pass isVerified prop to client component
- Add bilingual "not-allowed" translations

- Simplify message to cover broader error cases
- Fix typo: "performe" → "performed"
- Apply same changes to Croatian version

 fetchAllLocations projection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added tenantEmail and tenantEmailStatus fields to the MongoDB projection
in fetchAllLocations() so LocationCard can display email status indicators.

Previously these fields were always undefined in LocationCard because they
weren't included in the aggregation pipeline's $project stage.

LocationCard:
- Include email status in card info section display condition
- Remove emoji suffixes (icons already convey status visually)

LocationEditForm:
- Enable autoBillFwd and rentDueNotification toggles
- Only show email status when displayed email matches saved email
- Show unverified status when email is changed or for new emails
- Remove emoji suffixes from status messages
- Add left margin to status display

Messages (EN/HR):
- More descriptive email status messages in both languages
- LocationCard: "tenant email not verified" vs "Email not verified"
- LocationEditForm: Clearer explanations like "this e-mail address
  will need to be verified by the tenant"

Subject: [PATCH 23/24] security: add server-side validation for email status
 transitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement strict validation to prevent unauthorized email status changes:
- Force status to Unverified when email address changes
- Only allow client to reset status to Unverified (via reset button)
- Block client from upgrading status (Unverified→Verified, etc.)
- All status upgrades must happen server-side via verification links

This prevents attackers from:
- Submitting new emails with fake "verified" status
- Bypassing email verification by modifying client requests
- Escalating email status without proper verification flow
