 ## Release gates
 
+On 2026-10-22, the owner reported that password entry and the one-message authenticated SMTP transport test worked. The specific received-image rendering result was not captured. The campaign-specific test and live dispatch gates remain open.
+
 1. All P1 stories and T01-T32 applicable to the chosen provider pass.
 2. Sender domain and provider limits verified; the system can display provider rejection and halt safely.
 3. Unsubscribe route is tested end to end; a recorded opt-out takes effect before the next dispatch. Any manual mailbox procedure has an owner and a tested processing schedule.

 ## Current milestone
 
-F01-F04, F06, and F07 are implemented and locally verified. F07 imports constrained well-formed HTML and local image snapshots, with an isolated stored-content preview; the campaign footer belongs to F08. F05 has a successful unauthenticated STARTTLS 1.3 handshake, protected password storage tests, and an inline-image MIME pickup test. The authenticated internal send and inbox rendering are pending local password setup. Campaign sending remains unavailable.
+F01-F07 are implemented and locally verified. The owner reports the authenticated internal SMTP test worked after entering the password; detailed received-image rendering is not separately recorded. F08 now has review, full footer preview, campaign-specific internal test, and paused approval.

-- Enter the SMTP password locally with the HTA setup action, then run its one-message internal test and inspect the received HTML/CID image.
-- Enter the business postal address in local `config.ini` before campaign approval.
-- Implement campaign approval and in-app dispatch (F08-F09), including a full message preview with the required footer.

 ## Setup on this PC
 
-1. Copy `config.example.ini` to `config.ini` and edit local settings. Set `SMTP_TEST_TO` to the owner-controlled test inbox. `BUSINESS_POSTAL_ADDRESS` remains blank until you supply it; future campaign approval will require it. Never place the SMTP password in the INI.

 2. Run `C:\Windows\SysWOW64\cscript.exe //nologo tools\init-db.vbs` once to create `data\MassMailer.mdb`. It refuses to overwrite an existing database.
 3. Run `Start-MassMailer.cmd`. The launcher selects the configured script architecture and opens the MDB before starting the HTA. Use `C:\Windows\SysWOW64\cscript.exe //nologo tools\launch.vbs check` to check startup without opening the UI.
 4. Import a UTF-8 CSV with an `email` header. Optional columns are `business_name`, `source_reference`, and `acquired_at` (`YYYY-MM-DD`). Supply a source reference in the CSV or the form; preview and review rejected rows before importing.
-5. Enter opt-out replies in the suppression form. To prepare an internal transport test, press **Set or rotate SMTP password** and enter the password in the local console. Then press **Send one internal test** in the HTA. The test sends one HTML message with an inline image to `SMTP_TEST_TO`; no live test has been sent from this project yet.
-6. Put template files under `TEMPLATE_ROOT` and import them from the HTA. The accepted HTML subset and example are in [templates/README.md](templates/README.md). Imported versions are immutable snapshots; the preview currently shows the template content only. Campaign footer and approval are still in development.

+7. Fill in `BUSINESS_POSTAL_ADDRESS` in local `config.ini`. Enter a campaign name and subject, select an imported template, and press **Review message and recipients**. After checking the full preview, send the campaign-specific test to `SMTP_TEST_TO` and confirm it arrived. Approval records paused deliveries; it does not start sending.
