+Do not copy `internal/web/view/templates` into mockups. Do not mark `<main>` as `ops`/`form` to pick width. Do not fix empty columns, Host/Type height, or split Save/Delete with one-off CSS.
+
+Compose screens from `stack`, `pair`, `measure`, `fill`, `field-row`, `actions-row`:
+- Two peer jobs → `pair` (one child shrinks to `measure`).
+- Tables/logs/DNS → `fill` (nowrap + overflow-x on the card). Add-to-list is a `measure` row inside that card, not a second card above it.
+- Confirm/login/user form → `measure`.
+- Host ‖ Type and two equal inputs → `field-row` (shared grid row, not two `.code` paddings).
+- Save + Delete → `actions-row` inside the card; never submit inside `<form>` and danger after `</form>`.
+- Danger zone is the second column of the last `pair`, never a full-width `fill`.
+- Card chrome is title + optional `?` + body + actions. Help is not sprinkled later.
+- Phone: `pair` stacks; `field-row` does not; tables become lists.
+- One screen is one HTML file. Shared chrome is `shell.js`. Do not put every screen in one hash-SPA.

 ## [Unreleased]
 
+### Added
+
+- docs: roadmap candidates **send-log-retention** (panel Settings for delivery
+  journal retention) and **domain-stats-auto-ratelimit** (30-day send stats per
+  domain/application, auto level-2 rate limit from avg × multiplier) — plans in
+  [docs/plans/](docs/plans/).
+
+- Postfix queue under `/data/postfix/queue` — deferred and active mail survive
+  container recreate and are included in full backups.
+- Full backup archives the whole operator project: `data/`, `docker-compose.yml`,
+  `.env`, and `certs/` (requires `.:/selfpost-deploy:ro` in compose). Restore
+  by unpacking into an empty project directory.
+
+### Changed
+
+- **Breaking:** full-backup archive layout — paths are prefixed with `data/`;
+  deploy files sit at the archive root. Old flat archives restore with
+  `tar xzf backup.tar.gz -C ./data` as before.
+- docs: operator guide, architecture, security, and backup UI updated for
+  self-contained backups and persistent queue.
+
+- docs: HTML mockups for a full panel UI refresh
+  ([docs/assets/panel-ui/](docs/assets/panel-ui/index.html)) — current screens,
+  agreed and candidate roadmap surfaces (queue-retries, inbound-relay,
+  dmarc-reports, panel-docs), a hybrid width (ops pages use the window, forms
+  keep a reading measure), and a 390px emergency layout. The stamp and brick
+  palette stay; extra nav icons are proposals only. Design artefact; the
+  running panel is unchanged.
+
+### Changed
+
+- docs: panel UI mockups after review — Status restored to live readings
+  (queue line, PTR, machine/process tables, Configuration); inbound MX DNS
+  check, recipient mode (list or any), and Danger zone beside recipients;
+  Backup and Settings as two-column ops pages; Save and Delete user on one
+  row; help «?» on domain cards; Host/name ‖ Type height matched to the live
+  panel (`b0ebe06`).
+
+- docs: panel UI design system and mockups rebuilt as separate pages
+  (`system.html`, `status.html`, `domain.html`, …), not one hash sheet.
+  Regions are `stack` / `pair` / `measure` / `fill`; Host ‖ Type is
+  `field-row`; Save + Delete is `actions-row`. Shared chrome is `shell.js`.
+
+- docs: panel UI mockups — add-domain sits in the list card (Domains and
+  Inbound); DMARC candidate screens drill into a domain roll-up and a
+  parsed aggregate report (aligned vs third-party fail), not a hub-only
+  summary.
+
+## [1.3.0] - 2026-08-14
+
+Security and quality after 1.2.5: domain-admin send-log authorization,
+fail-closed sign-in and application delete, level-2 rate-limit race fix,
+restore Resync, expanded tests, operator docs, release CI, and OFL for IBM
+Plex. Upgrading from 1.2.x is a tag bump; no migration.
+
+### Added
+
+- licence: the SIL Open Font License 1.1 text now travels with the IBM Plex
+  WOFF2 files (`internal/web/view/static/OFL.txt`). The image copies it next
+  to LICENSE and NOTICE under `/usr/share/doc/selfpost/`; the panel serves it
+  at `/static/OFL.txt`. OFL requires the licence to accompany the font.
+
+- docs: agreed roadmap item **queue-retries** — show this Postfix's retry
+  policy (first delay, backoff cap, queue lifetime) on Mail queue and on a
+  delivery's history, reading `postconf -h` once at panel start so a manual
+  override is visible. Plan: [docs/plans/queue-retries.md](docs/plans/queue-retries.md).
+  Explanation only; no attempt counter and no panel knobs. Not yet
+  implemented.
+
+### Security
+
+- The independent security review of the send-log authorization and
+  fail-closed fixes below (code-review plan § P7; reviewer model ≠ author
+  model) found no further issues: the domain scope holds on every query path,
+  a rate-limit refusal cannot consume window budget, and each failure residue
+  of the reordered application delete fails safe. Nothing was added to
+  [docs/security.md](docs/security.md) § Accepted risks; the review is
+  recorded in that file's header.

   still authenticate to Postfix. This matches the order domain deletion already
   used.
 
+- panel (GUI): a rejected rate-limit change on a domain's page now renders on
+  the danger surface (`.flash.error`) instead of the success one — it was
+  green with red text, reading as good news. Deleting a panel user now goes
+  through a confirmation page, the same pattern as domain deletion, instead of
+  a plain submit button next to Save with no confirmation at all.
+
+- panel (restore): after a backup is extracted and the version guard passes,
+  the panel runs one mail-path Resync on the first boot — OpenDKIM's tables
+  and Postfix's sender map are re-derived from SQLite and the daemons are
+  reloaded, so drift between the archive and the database is healed before
+  mail flows. Later starts skip that step; the Status page Reload button runs
+  the same Resync on demand. The `internal/backup` package comment now matches
+  this behaviour.
+
+- ci (GHCR): per-arch package tags (`X.Y.Z-amd64`, `X.Y.Z-arm64`) are dropped
+  after the manifest merge via the GitHub Packages API. The merge job had called
+  `docker buildx imagetools rm`, which is not a valid subcommand — cleanup failed
+  with a warning and the side-effect tags stayed in the registry.
+
 ### Changed
 
+- docs: operator and as-built docs aligned with the code after a full
+  pass — [architecture.md](docs/architecture.md) route table now marks
+  **global** routes (404 for domain administrators) and documents the
+  one-time restore Resync in Persistence; session/password and restore-session
+  wording corrected in [guide.md](docs/guide.md) and architecture (own-password
+  change vs admin reset, no "logout everywhere", immediate session restore on
+  the next request, PTR cache ≈1 min, decrypt has no version check, restore
+  Resync on first boot, domain add/delete/import and `POST /reload` global-only,
+  Settings DMARC global-only); [README.md](README.md) port-587 and quick-start
+  volume wording fixed; [security.md](docs/security.md) CSRF ADR points at
+  `authz.go` for route gating. No behaviour change.
+
+- docs: [guide.md](docs/guide.md) reorganised into **Installation**, **Instance
+  administration**, and **Domain administration** — DNS setup, operations,
+  rate limiting, and backup sections follow the instance/domain boundary
+  instead of mixing them. **Installation** now reads Ports → Local trial →
+  Initial setup → Full deployment (with the fixed image tag nested under it) →
+  Environment variables → Reverse proxy; the step-by-step production deploy and
+  per-proxy TLS commands move here from README's "Reference deploy" (README
+  keeps a short pointer). Internal (non-operator) environment variables move
+  to [architecture.md](docs/architecture.md) § Configuration; the guide keeps
+  a one-line pointer. **Full backup and restore** gains worked commands for
+  in-place restore, move-to-a-new-host, and encrypted-backup decrypt-first,
+  plus the version-mismatch error text. README anchors updated for the new
+  headings. No behaviour change.
+
+- docs: the 2026-08-13 full-tree review plan is complete — every phase (P0–P7)
+  is closed — and `docs/plans/code-review.md` is deleted per its own exit
+  criteria (history in git and in this file). The plan covered architecture,
+  quality, GUI, tests, and licence work; P0 was domain-admin send-log
+  authorization. The [roadmap](docs/roadmap.md)'s recommended order returns to
+  **queue-retries** and then **inbound-relay**; it still records
+  **schema-squash** (replace the 1.x SQLite migration chain with a 2.x baseline;
+  not a reason to cut a major on its own).
+
+- licence: [NOTICE](NOTICE) tells modifiers to update `SourceURL` in
+  `internal/legal/legal.go` (the value the panel footer actually injects), not
+  `layout.html`. Per-file `SPDX-License-Identifier` headers on the two command
+  packages were dropped so the tree is consistent; AGPL-3.0 does not require
+  them ([development.md](docs/development.md) § External libraries). Deleted the
+  completed `docs/plans/logrotate-mode.md` (history in git and
+  [1.2.3](#123---2026-08-12)).
+
+- ci: the release image is published only for a **published** GitHub Release
+  (`vX.Y.Z`) or a manual `workflow_dispatch` with an explicit SemVer version — a
+  bare git tag push no longer starts the build. `release.yml` listens for
+  `release: published`, checks out that tag (not `main` HEAD), e2e-gates each
+  native arch build, merges `X.Y.Z-amd64` and `X.Y.Z-arm64` into one manifest,
+  then removes the per-arch tags from GHCR via the GitHub Packages API so
+  operators see only `ghcr.io/mixeme/selfpost:X.Y.Z` (what
+  `deploy/docker-compose.yml` pins). A dispatch whose version input is missing
+  or not `X.Y.Z` fails in `prepare`. [development.md](docs/development.md)
+  documents draft vs published releases, why deleting a release tag converts
+  it back to draft, and Gitea → GitHub tag-mirror pitfalls (do not prune release
+  tags on GitHub; a mirrored `v1.0.0` still runs that tag's `on: push: tags`
+  workflow).
+
+- test: the authorization and sign-in surfaces that had no tests now have them.
+  The login limiter is covered for its ceiling, its per-address scope, the reset
+  at the end of a window and the sweep that keeps finished buckets out of
+  memory; sign-in for a successful session, for refusals that do not reveal
+  which usernames exist, and for a lockout that a correct password cannot
+  bypass; the one-time setup link for creating the first administrator, closing
+  afterwards, rejecting a wrong or expired token, and refusing credentials the
+  panel would not accept later. Every global-only route (`/users`, `/backup`,
+  domain import, `/status`, `/mail-queue`, `/system-log`, domain add and delete,
+  reload) is checked to answer a domain administrator — and a request with no
+  principal — with 404, the check that would have caught the send-log leak.
+
+- test: restore is covered as the operator performs it, in process. A backup is
+  downloaded from a running panel through `POST /backup` (plain and encrypted),
+  unpacked the way `tar -xzf` unpacks it onto the `/data` bind mount, and a
+  second panel is booted on the result through the startup order the panel
+  itself uses — version guard, database, one Resync when restoring, then
+  services and the HTTP application. The restored panel shows the domain and
+  journal the archive carried, finds the DKIM key, SASL database and Postfix
+  sender map where its configuration says they are, does not reopen the
+  one-time setup link, and still honours a session that predates the backup.
+  Drifted on-disk maps are healed by that Resync step
+  (`TestResyncAfterRestoreHealsDriftedMaps`). A data directory left by another
+  version is refused with both versions named and the manifest kept. `serveHTTP`
+  is split in two so that composition can be started without binding a port; no
+  behaviour change.
+
+- test (e2e): the CoreDNS image is pinned to `1.14.6` instead of `latest`, so
+  the release gate cannot change under a commit between two runs. The level-1
+  rate-limit failure message quoted `RATE_LIMIT_MESSAGES_PER_IP=5` while the
+  stand sets `50`.

+
+- panel (GUI, accessibility): the Deliveries fragment's `hx-get` and pagination
+  links now `urlquery`-encode the `domain`/`app` filters instead of splicing

-### 1. Fetch the base files
+The compose file always publishes **465** and **587**; Postfix listens on 587
-
+only when `SUBMISSION_ENABLE=true` (see [Ports](docs/guide.md#ports)). Bump the
-```sh
+pinned image tag deliberately when upgrading, never `:latest` ([why](docs/guide.md#fixed-image-tag)). Optional

+variables (`TRUSTED_PROXY_CIDR`, rate limits, retention): see [Environment
-curl -O https://raw.githubusercontent.com/mixeme/selfpost/main/deploy/docker-compose.yml
+variables](docs/guide.md#environment-variables).
-curl -O https://raw.githubusercontent.com/mixeme/selfpost/main/deploy/.env.example
-cp .env.example .env
-```
-
-Edit `.env` — at minimum set `SELFPOST_HOSTNAME` to your mail hostname (bare
-FQDN, e.g. `mail.example.com`). It must match the PTR record you request from
-your provider and the certificate your proxy will obtain.
-
-### 2. Reverse proxy and TLS
-
-Pick one proxy. In every case the proxy terminates HTTPS for the panel; the
-same certificate must end up under `./certs` as `fullchain.pem` and
-`privkey.pem` so Postfix can serve it on 465 (and 587 if enabled). The proxy
-must **pass the original `Host` header** — details and rationale:
-[Reverse proxy](docs/guide.md#reverse-proxy-mandatory).
-
-**Apache (recommended, on the host).** Install Apache with `ssl`, `proxy`, and
-`proxy_http` enabled. Copy
-[deploy/apache/selfpost-vhost.conf](deploy/apache/selfpost-vhost.conf) into your
-vhost directory, replace `mail.example.com` with your hostname, enable the site,
-then issue a certificate:
-
-```sh
-sudo certbot --apache -d mail.example.com
-```
-
-Point `./certs` at the PEM files certbot wrote (symlink is fine):
-
-```sh
-ln -s /etc/letsencrypt/live/mail.example.com certs
-```
-
-**nginx (containerised).** From the `deploy/` directory, merge the nginx
-fragment and issue the first certificate before nginx can serve HTTPS:
-
-```sh
-docker compose -f docker-compose.yml -f nginx/docker-compose.nginx.yml \
-  run --rm certbot certonly --webroot -w /var/www/certbot \
-  -d mail.example.com --email you@example.com --agree-tos --no-eff-email
-
-docker compose -f docker-compose.yml -f nginx/docker-compose.nginx.yml up -d
-```
-
-Edit [deploy/nginx/nginx.conf.example](deploy/nginx/nginx.conf.example) and
-replace `mail.example.com` first. The fragment bind-mounts certbot's output into
-both nginx and SelfPost.
-
-**Caddy (containerised, automatic ACME).** Edit
-[deploy/caddy/Caddyfile](deploy/caddy/Caddyfile) and the `<hostname>` placeholders
-in [deploy/caddy/docker-compose.caddy.yml](deploy/caddy/docker-compose.caddy.yml),
-then:
-
-```sh
-docker compose -f docker-compose.yml -f caddy/docker-compose.caddy.yml up -d
-```
-
-Verify Caddy's on-disk cert path for your version before relying on the
-default mount — see the comment at the top of the Caddy compose fragment.
-
-**Traefik (containerised).** Edit the `Host(...)` label and ACME email in
-[deploy/traefik/docker-compose.traefik.yml](deploy/traefik/docker-compose.traefik.yml),
-start the stack, then extract PEM files for Postfix whenever Traefik issues or
-renews a certificate:
-
-```sh
-docker compose -f docker-compose.yml -f traefik/docker-compose.traefik.yml up -d
-./traefik/extract-cert.sh ./traefik/letsencrypt/acme.json mail.example.com ./traefik/extracted-certs
-```
-
-Schedule `extract-cert.sh` (cron or a timer) alongside Traefik's renewals.
-
-### 3. Start SelfPost
-
-If you used Apache on the host (step 2, first option), start only the base
-compose file from your `selfpost/` directory:
-
-```sh
-docker compose up -d
-```
-
-The nginx/Caddy/Traefik fragments from step 2 already include `docker compose up
--d` — skip this if you ran one of those.
-
-**Get the setup URL** — open it in a browser to create the admin account
-([first boot](#quick-start)):
-
-```sh
-docker compose logs selfpost 2>&1 | grep -m1 'http'
-```
-
-```sh
-cat ./data/setup-token
-```
-
-The file is deleted as soon as setup completes. If logs are shipped to a
-central aggregator, prefer `cat ./data/setup-token` so the bearer token does
-not enter the log pipeline.
-
-### 4. DNS and sending
-
-Before sending real mail:
-
-1. Confirm PTR/rDNS for the server IP points at `SELFPOST_HOSTNAME` (Status
-   page → *Re-check*).
-2. For each domain you add in the panel, publish SPF, DKIM, and DMARC at the
-   same time ([DNS setup](docs/guide.md#dns-setup)).
-3. Warm up a new IP gradually ([IP warmup](docs/guide.md#ip-warmup)).
-
-### Ports and upgrades
-
-The compose file maps **465** (always) and **587** (when
-`SUBMISSION_ENABLE=true`). Bump the pinned image tag deliberately when
-upgrading — never use `:latest` ([why](docs/guide.md#fixed-image-tag)).
-
-Optional variables (`TRUSTED_PROXY_CIDR`, rate limits, retention): see
-[Environment variables](docs/guide.md#environment-variables).

+
+**Internal env vars.** The following are read by the panel or startup scripts
+but are not part of the operator interface — not meant to be changed in a
+normal deployment; documented here so an accidental override reads as
+unsupported rather than as a missing doc:
+
+- **Panel paths and tuning:** `SELFPOST_DATA_DIR` (`/data`), `SELFPOST_DB_PATH`

+  (`/data/setup-token`), `PANEL_HTTP_ADDR` (`:8080`),
+  `JOURNAL_MILTER_SOCKET` (`/run/selfpost/journal.sock`), `MAIL_LOG`
+  (`/data/log/mail.log` — read by the panel and written by Postfix, so a change
+  here has to be matched in `build/postfix-config.sh`),
+  `PANEL_COOKIE_SECURE` (`true`), `OPENDKIM_SOCKET`
+  (`/run/opendkim/opendkim.sock`), `OPENDKIM_DIR` (`/data/opendkim`),
+  `DKIM_SELECTOR_DEFAULT` (`selfpost`), `SASL_DB_PATH`
+  (`/data/sasl/sasldb2`), `SASL_REALM` (defaults to `SELFPOST_HOSTNAME`),
+  `POSTFIX_DIR` (`/data/postfix`), `POSTFIX_SENDER_LOGIN_MAPS`
+  (`/data/postfix/sender_login_maps` — read by Postfix config only; the panel
+  always writes `<POSTFIX_DIR>/sender_login_maps`, so overriding this env alone
+  desyncs the map Postfix reads from the file the panel maintains),
+  `POSTFIX_QUEUE_DIR` (`/data/postfix/queue` — set in `build/postfix-config.sh`),
+  `SELFPOST_DEPLOY_ROOT` (`/selfpost-deploy` — operator project directory for
+  full backups; mount `.:/selfpost-deploy:ro` in compose).
+- **Milter and Postfix startup:** `MILTER_CONNECT_TIMEOUT` (`15s`),
+  `MILTER_COMMAND_TIMEOUT` (`15s`), `MILTER_CONTENT_TIMEOUT` (`30s`),
+  `MILTER_WAIT_TIMEOUT` (`30` seconds).
+- **Background maintenance:** `TLS_RELOAD_INTERVAL_SECONDS` (`86400` — daily
+  `postfix reload` to pick up renewed certificates),
+  `LOGROTATE_INTERVAL_SECONDS` (`21600` — check `mail.log` rotation every six

Знак и палитра из листа утверждения не меняются. HTML в <code>docs/assets/panel-ui/</code>, не вёрстка <code>internal/web</code>.</p>

+  <h3>Гибрид</h3>
+  <p>Навигация прижата влево. Ops-страницы (Status, Deliveries, очередь, лог, Backup, Settings, DMARC, inbound) занимают остаток до <strong>90rem (~1440px)</strong>. Backup — полный бэкап ‖ импорт. Settings — учётные данные ‖ DMARC (у domain-admin остаётся одна узкая карточка). Таблица Users — <code>fill</code>. Одиночные формы (подтверждения, форма пользователя) остаются <strong>42rem и выровнены влево</strong>. Login и setup — по-прежнему узкий центрированный блок.</p>

+  <h2>Зачем</h2>
+  <p>Первый макет скопировал грамматику живой панели: страница помечается <code>ops</code> или <code>form</code>, карточки стопкой, пара полей — два независимых <code>.code</code>, Save внутри <code>&lt;form&gt;</code>, Delete снаружи. Дальше каждая мелочь чинилась отдельно — как в <code>panel.css</code> годами. Новый интерфейс должен <strong>не давать собрать</strong> пустую колонку, разные высоты Host/Type и кнопки на двух строках.</p>
+  <p>Три оси, которые больше не выбираются «на глаз» у каждой страницы:</p>
+  <ol>
+    <li><strong>Регион</strong> — как блок занимает ширину окна.</li>
+    <li><strong>Карточка</strong> — заголовок, справка, тело, действия.</li>
+    <li><strong>Контрол</strong> — одно поле или пара полей одной высоты.</li>
+  </ol>
+</section>
+
+<section id="regions">
+  <h2>Регионы</h2>
+  <p>Страница — это <code>stack</code> регионов, не класс на <code>&lt;main&gt;</code>. Оболочка одна: навбар прижат влево, контент забирает остаток. Навбар не прыгает, когда меняется содержимое.</p>

+
+**GitHub Release vs GHCR.** The public [Releases](https://github.com/mixeme/selfpost/releases)
+page lists only **published** releases. A draft is visible to maintainers only —
+it looks like “no releases” to everyone else. CI does not create or publish the
+GitHub Release; you do that in the UI. Deleting a release’s git tag on GitHub
+(or re-pushing tags while cleaning the registry) converts a published release
+back into a **draft** — that matches “I published three times and it keeps
+disappearing”. After publish, leave the tag on GitHub; clean up only unwanted
+GHCR package versions, not the git tag.
+
+Push workflow and source changes to **github.com/mixeme/selfpost** before

+
+**Gitea → GitHub tag mirror.** If every tag push from Gitea is mirrored to
+GitHub, two things follow:
+
+1. **GitHub Release tags must not be deleted on GitHub.** Many mirror setups
+   prune remote tags that are absent on Gitea (or re-push with `--force` /
+   `--prune`). Deleting `v1.0.0` / `v1.3.0` on GitHub converts a published
+   Release back to draft. Mirror **branches and new tags forward**; do not
+   delete release tags on the GitHub side. GHCR cleanup is package versions in
+   the UI — not `git push github --delete` and not tag prune on the mirror.
+
+2. **Tag push runs the workflow file at that tag's commit**, not `main`. `v1.0.0`
+   still points at a commit whose `release.yml` has `on: push: tags` and no

+
+On first start the one-time setup URL is printed in the container log
+(`docker compose logs -f`) and written to `/data/setup-token` inside the
+container — `./data/setup-token` on the host, mode `0600` — then deleted when
+setup completes. The link is `https://<SELFPOST_HOSTNAME>/setup/<token>` (path
+token, not a query string), valid for ten minutes. Open it to choose the
+administrator username and password — until then the panel has no login. If
+this host ships container logs to a central aggregator, prefer reading the
+file:
+
+```sh
+docker compose exec selfpost cat /data/setup-token
+```
+
+### Full deployment
+
+Production layout: one `docker-compose.yml`, a `.env`, persistent `./data`, and
+TLS PEM files at `./certs` (read by Postfix on 465/587). The panel is reached
+only through a [reverse proxy](#reverse-proxy-mandatory) on 443 — port 8080 is
+bound to localhost in the default compose file.
+
+| Artefact | Path |
+|---|---|
+| Compose file (fixed image tag) | [deploy/docker-compose.yml](../deploy/docker-compose.yml) |
+| Environment template | [deploy/.env.example](../deploy/.env.example) |
+| Apache vhost (recommended) | [deploy/apache/selfpost-vhost.conf](../deploy/apache/selfpost-vhost.conf) |
+| nginx | [deploy/nginx/](../deploy/nginx/) |
+| Caddy | [deploy/caddy/](../deploy/caddy/) |
+| Traefik | [deploy/traefik/](../deploy/traefik/) |
+
+**1. Fetch the base files.**
+
+```sh
+mkdir -p selfpost/data selfpost/certs && cd selfpost
+curl -O https://raw.githubusercontent.com/mixeme/selfpost/main/deploy/docker-compose.yml
+curl -O https://raw.githubusercontent.com/mixeme/selfpost/main/deploy/.env.example
+cp .env.example .env
+```
+
+Edit `.env` — at minimum set `SELFPOST_HOSTNAME` to your mail hostname (bare
+FQDN, e.g. `mail.example.com`). It must match the PTR record you request from
+your provider and the certificate your proxy will obtain. See [Environment
+variables](#environment-variables) for the full list.
+
+**2. Reverse proxy and TLS.** Pick and set up one proxy — see [Reverse proxy
+(mandatory)](#reverse-proxy-mandatory) for the per-proxy commands. The same
+certificate must end up under `./certs` as `fullchain.pem` and `privkey.pem`
+so Postfix can serve it on 465 (and 587 if enabled).
+
+**3. Start SelfPost.** If you used Apache on the host (the recommended
+option), start only the base compose file from your `selfpost/` directory:
+
+```sh
+docker compose up -d
+```
+
+The nginx/Caddy/Traefik fragments already include `docker compose up -d` —
+skip this if you ran one of those.
+
+**Get the setup URL** — open it in a browser to create the admin account (see
+[Initial setup](#initial-setup)):
+
+```sh
+docker compose logs selfpost 2>&1 | grep -m1 'http'
+```
+
+```sh
+cat ./data/setup-token
+```
+
+**4. DNS and sending.** Before sending real mail:
+
+1. Confirm PTR/rDNS for the server IP points at `SELFPOST_HOSTNAME` (Status
+   page → *Re-check*) — see [Server-level DNS](#server-level-dns-ptrrdns).
+2. For each domain you add in the panel, publish SPF, DKIM, and DMARC at the
+   same time ([Domain-level DNS](#domain-level-dns-spf-dkim-dmarc)).
+3. Warm up a new IP gradually ([IP warmup](#ip-warmup)).
+
+#### Fixed image tag
+
+`deploy/docker-compose.yml` pins an explicit version (`ghcr.io/mixeme/selfpost:X.Y.Z`),
+deliberately never `:latest`. The current pin is `1.3.0`. Intermediate
+CHANGELOG sections (`0.2.0`…`0.6.0`) record development cuts from before that
+image was published. Pinning matters because of the backup version check (see
+[Full backup and restore](#full-backup-and-restore)): the panel binary's
+embedded version and the image tag that produced it are the same value by
+construction (the release CI stamps both from one git tag — see
+`.github/workflows/release.yml`), so the pin is what makes "restore into the
+same version" a checkable fact rather than a guess. Upgrade by bumping the tag
+deliberately, not by riding a moving target — see [Upgrading](#upgrading).

+proxy in front of it is not optional. The proxy is also the project's only

+service share one hostname — the common case — it's genuinely one certificate
+serving both.
 
-Two different scopes — don't confuse them:
+SelfPost isn't tied to a specific proxy; pick whichever fits your host:
 
-**Server level (once, for the machine itself):**
+| Proxy | Where certs live | Fragment |
-- **PTR/rDNS** for the server's IP, pointing at its mail hostname. Most
+|---|---|---|
-  receiving mail servers weigh this heavily; get it from whoever assigns the IP
+| **Apache** (default/recommended) | Host disk, via the certbot Apache plugin — PEM files ready to bind-mount, no extraction step. | [deploy/apache/selfpost-vhost.conf](../deploy/apache/selfpost-vhost.conf) |
-  (hosting provider's panel/support), not from your own DNS zone.
+| nginx | Host disk, via a certbot sidecar container — same PEM-ready shape as Apache. | [deploy/nginx/](../deploy/nginx/) |
+| Caddy | Automatic ACME, zero extra containers — simplest, but its on-disk cert path is versioned internal layout, not a stable API; verify it for the Caddy version you run. | [deploy/caddy/](../deploy/caddy/) |
+| Traefik | Bundled inside `acme.json` — needs a small extraction script to produce standalone PEM files. | [deploy/traefik/](../deploy/traefik/) |
 
-**Domain level (for *every* sending domain you add in the panel):**
+Apache is the recommended default because the certbot Apache plugin already
-- **SPF** — a TXT record on the domain authorizing this server to send on its
+writes plain `fullchain.pem`/`privkey.pem` files to a predictable path with no
-  behalf (e.g. `v=spf1 a mx ip4:<server IP> -all`, adjusted to your setup).
+extra moving parts between "certificate issued" and "Postfix can read it."
-- **DKIM** — a TXT record with the exact value the panel shows on that
-  domain's page (`domain page → DKIM TXT record`), one selector per domain.
-- **DMARC** — a `_dmarc` TXT record. The panel suggests `p=none` (monitoring
-  only, safe to publish immediately). On a send-only relay the sending domain
-  often has no inbox, so `rua=` is optional — configure a default report address
-  in *Settings* or per domain when you have a mailbox that receives inbound mail
-  elsewhere. If `rua=` points at another domain, publish `_report._dmarc` on that
-  hub domain too; the panel checks it. Public mail hosts (Gmail, Outlook, …)
-  cannot be used as external report destinations.
 
-Skipping any of the three per-domain records is the single most common reason
+**The proxy needs no security configuration of its own.** The panel emits its
-mail lands in spam even though SelfPost delivered it correctly — DKIM passing
+own `Content-Security-Policy`, `Strict-Transport-Security`, `X-Frame-Options`,

-plus the domain's SPF, DMARC, and (when configured) DMARC report-authorisation

-shallow — it looks for a mechanism that literally covers this server's address
-and does not follow `include:` or `redirect=`, so a record that authorizes the
-server through an include is reported as "cannot tell" rather than as a failure.
 
-## IP warmup
+**Apache (recommended, on the host).** Install Apache with `ssl`, `proxy`, and
+`proxy_http` enabled. Copy
+[deploy/apache/selfpost-vhost.conf](../deploy/apache/selfpost-vhost.conf) into your
+vhost directory, replace `mail.example.com` with your hostname, enable the site,
+then issue a certificate:
 
-A brand-new IP has no sending history, so receiving servers are cautious with
+```sh
-it regardless of how correct your DKIM/SPF/DMARC are. Start with low volume to
+sudo certbot --apache -d mail.example.com
-a domain, increase gradually over days/weeks rather than sending everything on
+```
-day one, and check the IP against major blocklists (Spamhaus and similar)
-before and during warmup. This is inherent to how mail reputation works on the
-public internet, not something SelfPost's configuration can shortcut.
 
-## Operations
+Point `./certs` at the PEM files certbot wrote (symlink is fine):
+
+```sh
+ln -s /etc/letsencrypt/live/mail.example.com certs
+```
+
+**nginx (containerised).** From the `deploy/` directory, merge the nginx
+fragment and issue the first certificate before nginx can serve HTTPS:
+
+```sh
+docker compose -f docker-compose.yml -f nginx/docker-compose.nginx.yml \
+  run --rm certbot certonly --webroot -w /var/www/certbot \
+  -d mail.example.com --email you@example.com --agree-tos --no-eff-email
+
+docker compose -f docker-compose.yml -f nginx/docker-compose.nginx.yml up -d
+```
+
+Edit [deploy/nginx/nginx.conf.example](../deploy/nginx/nginx.conf.example) and
+replace `mail.example.com` first. The fragment bind-mounts certbot's output into
+both nginx and SelfPost.
+
+**Caddy (containerised, automatic ACME).** Edit
+[deploy/caddy/Caddyfile](../deploy/caddy/Caddyfile) and the `<hostname>` placeholders
+in [deploy/caddy/docker-compose.caddy.yml](../deploy/caddy/docker-compose.caddy.yml),
+then:
+
+```sh
+docker compose -f docker-compose.yml -f caddy/docker-compose.caddy.yml up -d
+```
+
+Verify Caddy's on-disk cert path for your version before relying on the
+default mount — see the comment at the top of the Caddy compose fragment.
+
+**Traefik (containerised).** Edit the `Host(...)` label and ACME email in
+[deploy/traefik/docker-compose.traefik.yml](../deploy/traefik/docker-compose.traefik.yml),
+start the stack, then extract PEM files for Postfix whenever Traefik issues or
+renews a certificate:
+
+```sh
+docker compose -f docker-compose.yml -f traefik/docker-compose.traefik.yml up -d
+./traefik/extract-cert.sh ./traefik/letsencrypt/acme.json mail.example.com ./traefik/extracted-certs
+```
+
+Schedule `extract-cert.sh` (cron or a timer) alongside Traefik's renewals.

-## Backup, restore, and moving a single domain
+**Restore** means unpacking that archive into an **empty project directory**
+(not into `./data` alone) and starting a container of the **exact same image
+version** that created it — SelfPost refuses to start otherwise and tells you
+which tag to use. On the first successful start after restore, `data/manifest.json`
+from the archive is **deleted** — it guards only that one boot, so a later
+in-place upgrade is not blocked. On that same first boot the panel also runs
+one **Resync** — OpenDKIM's tables and Postfix's sender map are re-derived from
+SQLite and both daemons are reloaded, healing any drift between the extracted
+files and the database (the Status page's *Reload configuration* button runs
+the same step on demand). This is why the compose file pins a fixed tag rather
+than `:latest`: without a known version, there'd be no way to tell which image
+restoring a given backup actually requires (see [Fixed image
+tag](#fixed-image-tag)).
 
-Two related but distinct operations
+**Restoring in place** (same host — recovering from data loss, or rolling

-  ```sh
-  docker exec <container> selfpost-backup > selfpost-backup.tar.gz

-  **Restore** means unpacking that archive into a fresh `/data` bind mount and
-  starting a container of the **exact same image version** that created it —
-  SelfPost refuses to start otherwise and tells you which tag to use. On the
-  first successful start after restore, `manifest.json` from the archive is
-  **deleted** — it guards only that one boot, so a later in-place upgrade is
-  not blocked. This is why the compose file pins a fixed tag rather than

-SelfPost can do for you.
 
-### Encrypting a backup or export
+A version mismatch at step 5 refuses to start and leaves `/data` untouched —
+the panel exits with a message naming the tag to use, e.g.:
+
+```
+backup: this backup was created by SelfPost 1.2.3 but this image is 1.3.0 — restore into the matching image (selfpost:1.2.3)
+```
+
+Fix the tag in `docker-compose.yml`, `docker compose pull && docker compose up
+-d` again — the manifest is still there because the failed boot never got to
+delete it.
+
+**Moving to a different host** is the same flow: create an empty project
+directory, unpack the backup there, edit `.env` (and `docker-compose.yml` if
+needed) for the new hostname or proxy, then `docker compose up -d`. The archive
+carries `certs/` from the old host — re-issue certificates when the hostname or
+IP changes. Set up the reverse-proxy vhost separately (not in the backup).
+
+**Restoring an encrypted (`.spbk`) backup** needs a running container to
+decrypt it first — any container with the `selfpost-backup` CLI works; decryption
+does not read `/data` and performs no version check. Start one normally
+(step 5, but on an empty project you have not unpacked yet), then:
+
+```sh
+docker exec -i <container> selfpost-backup -decrypt < backup.spbk > selfpost-backup.tar.gz
+```
+
+Stop it, wipe the project directory again, and continue from step 2 above with
+the resulting `.tar.gz` — see [Encrypting a backup or
+export](#encrypting-a-backup-or-export) for the decrypt command's password
+options.
+
+**Archives from older SelfPost versions** (flat layout: `manifest.json` and
+`selfpost.db` at the archive root, no `data/` prefix, no deploy files) restore
+with the previous procedure: `tar xzf backup.tar.gz -C ./data` into a project
+that already has `docker-compose.yml` and `.env`.
+
+Restoring an archive taken **before** a session row was removed can bring
+that session back: session rows travel with the backup, and a browser that
+still holds the matching cookie is signed in again on the next request if the
+restored row's idle expiry has not passed. `POST /logout` removes only the
+current session; there is no "logout everywhere". Changing your own password
+on `/settings` deletes your other sessions, but a global administrator
+resetting another user's password on `/users` does not invalidate that user's
+existing sessions.
+
+**Alternative: archive `./data` while stopped.** If the service can be taken
+offline, `docker compose down` then `tar czf selfpost-data.tar.gz ./data` on
+the host is safe — nothing is writing to SQLite. Unlike the panel/CLI backup
+this sweeps in `./data/log/` too, which is Postfix's raw log and usually the
+bulk of the archive; add `--exclude=./data/log` if you only want the state.
+Do **not** tar `./data` while the container is running: the database uses
+WAL mode and a naive copy can capture an inconsistent snapshot. The
+panel/CLI backup remains preferable when you cannot afford downtime because
+it takes a consistent SQLite snapshot via the Backup API on a live
+container.

+admin password hash (full backup), TLS private keys and `.env` (full backup),
+or working application credentials (domain export) in the clear or in

-deliberately, not by riding a moving target.
+- **DMARC** — a `_dmarc` TXT record. The panel suggests `p=none` (monitoring
+  only, safe to publish immediately). On a send-only relay the sending domain
+  often has no inbox, so `rua=` is optional — configure a default report address
+  in *Settings* (see [Settings](#settings)) or per domain when you have a
+  mailbox that receives inbound mail elsewhere. If `rua=` points at another
+  domain, publish `_report._dmarc` on that hub domain too; the panel checks
+  it. Public mail hosts (Gmail, Outlook, …) cannot be used as external
+  report destinations.
+
+Skipping any of the three records is the single most common reason mail
+lands in spam even though SelfPost delivered it correctly — DKIM passing
+doesn't help if SPF/DMARC are absent. **Whenever you add a new domain in the
+panel, add its DNS records at the same time**, not later.
+
+Each domain's page shows a *DNS status* card comparing the published DKIM
+record against the key this server signs with, plus the domain's SPF,
+DMARC, and (when configured) DMARC report-authorisation records. Results are
+cached for a few minutes; use *Re-check* right after publishing a record.
+The SPF check is deliberately shallow — it looks for a mechanism that
+literally covers this server's address and does not follow `include:` or
+`redirect=`, so a record that authorizes the server through an include is
+reported as "cannot tell" rather than as a failure.
+
+Server-level DNS (the PTR/rDNS record) is a separate, once-per-machine scope
+— see [Server-level DNS](#server-level-dns-ptrrdns).
+
+### IP warmup
+
+A brand-new IP has no sending history, so receiving servers are cautious with
+it regardless of how correct your DKIM/SPF/DMARC are. Start with low volume to
+a domain, increase gradually over days/weeks rather than sending everything on
+day one, and check the IP against major blocklists (Spamhaus and similar)
+before and during warmup. This is inherent to how mail reputation works on the
+public internet, not something SelfPost's configuration can shortcut.
+
+### Rate limiting — level 2 (domain and application)
+
+Level 2 is optional, configured on each domain's page, and layers on top of
+the always-on [level-1 IP backstop](#rate-limiting--level-1-ip-backstop).
+Level-2 ceilings cannot exceed level 1 (the panel shows the level-1 values
+and rejects higher numbers). When a level-2 ceiling is exceeded, Postfix
+returns a 4xx and the refusal is recorded in [Deliveries](#deliveries) as
+`rejected`.
+
+**Level 2 — domain** — a message ceiling and window for **every** client IP
+sending as that domain. When unset, only level 1 applies for non-privileged
+senders.
+
+**Level 2 — application (trusted IPs)** — optional override on an
+application: list one or more client IPs and a ceiling **strictly above**
+the domain limit (still ≤ level 1). Connections from those IPs use the
+application ceiling and skip the domain check. Other IPs stay under the
+domain limit (or level 1 alone). An application override without trusted
+IPs is inactive.
+
+**Level 2 is best-effort, not a guarantee.** It runs inside the
+journal-milter and is deliberately fail-open: if the rate-limit lookup hits
+a store error, or the connecting client's IP is not available to the
+milter, level 2 is skipped and the message is accepted rather than held up.
+Level 1 is the backstop that keeps working even when level 2 cannot run.
+
+### Deliveries
+
+`/deliveries` is a searchable send log with server-side filters by domain
+and application. A row identifies its message and nothing more — time,
+sender, recipient, subject and status `queued` (accepted, not yet
+delivered), `sent` (handed off successfully), `deferred` (Postfix is
+retrying), `bounced` (final failure), or `rejected` (refused — for example
+by a [level-2 rate limit](#rate-limiting--level-2-domain-and-application));
+*Details* opens that row's own page (`/deliveries/{id}`). That page carries
+the sending domain, the application it was submitted under, the Postfix
+queue id and the journal id, beside the message's history — when it was
+accepted and what Postfix later reported for the recipient — and, under
+both, the `mail.log` lines for its queue id: the connection to the
+receiving server, the server's reply, and the status that reply was filed
+as. Rows outlive `mail.log`, so an older message's lines may have rotated
+away; the page says so. Retention is controlled by
+`SEND_LOG_RETENTION_DAYS`.
+
+### Exporting and importing a single domain
+
+Domain page → *Export domain* to write the file, *Backup* → *Import a
+domain* to read it back in. This moves one domain — its DKIM key and its
+applications' **working** SASL passwords — to a different SelfPost instance
+without regenerating anything, so DNS (the DKIM TXT record) doesn't need to
+change. Unlike a full restore (see [Full backup and
+restore](#full-backup-and-restore)), this works across different
+hostnames/instances. *Import* is global-administrator only; *export* is
+available to any user who can access the domain, **including a domain-admin**
+for a domain assigned to them — so a domain-admin can walk away with that
+domain's working SASL passwords in the clear. Weigh that when deciding which
+domains to assign to a domain-admin account.
+
+A domain export is a secret in the same way a full backup is, and can be
+encrypted the same way — see [Encrypting a backup or
+export](#encrypting-a-backup-or-export).

-## Verdict
-
-SelfPost is a compact, well-bounded 1.x product: one image, one SQLite file,
-thin `domain`/`app` services for multi-store writes, a fail-open journal
-milter with a Postfix level-1 backstop, and documentation that is unusually

-Go lines, ~5.8k unit-test lines, ~1.2k HTML, 749 CSS, 281 JS). Comments
-explain decisions rather than restating code.
-
-The outstanding defect is **send-log authorization for domain administrators**
-(confidentiality). After that, the work is tightening a few fail-open paths,
-catching docs that froze at “single administrator”, small GUI bugs from the
-1.2.x layout pass, and filling test gaps around auth/RBAC. Do **not** use this

-## How to read this file
-
-Findings are grouped by the sixteen review questions. Each finding has a
-severity (**H**igh / **M**edium / **L**ow / **I**nfo). The implementation
-checklist at the end is the work queue; it names the model for each step.
-
-**Models** (from [development.md](../development.md)):
-
-| Kind of work | Model |
-|---|---|
-| Security, infra, mail path, permissions, open-relay risk | **Opus** |
-| UI / JS / CSS, templates, documentation (English) | **Sonnet** |
-| Trivial mechanics: retarget links, grep, compose bump, comment fixes | **Haiku** |
-| Security **review** of a diff (not authorship) | **Fable** |
-
-Reviewers must not be the author of the code under review.
-
----
-
-## 1. Architecture / structure
-
-**Proportionate.** Composition root in `cmd/panel` (HTTP + journal-milter +
-log-tailer, one `*store.Store`). `internal/domain` and `internal/app` own
-multi-store writes and rollback. Adapters (`postfix`, `milter`, `logtail`,
-`dnscheck`, `health`, `backup`, `secretfile`) are the only infrastructure-aware
-code. Interfaces exist where they break import cycles or enable fakes
-(`domain.Applications`, `app.SenderMaps`, `milter.Store`, `logtail.StatusStore`)
-— not as a DI framework.
-
-Handlers may call `store` directly for single-table reads (documented in
-[architecture.md](../architecture.md) § Code layers). That is followed for
-sessions, send-log queries, users, and DMARC settings. It is not a layering
-violation; it is an incomplete service boundary that will hurt if those
-surfaces keep growing.
-
-No circular Go imports. `MaxOpenConns(1)` on SQLite is an intentional
-single-connection trade-off for the three in-process roles.
-
-| Sev | Finding |
-|---|---|
-| **M** | Users, send-log listing, and global DMARC settings have no service; handlers talk to `store`. Fine at current size; do not invent a service until a second writer appears. |
-| **L** | `auth.RequireGlobal` (`internal/web/auth/middleware.go`) is unused; handlers duplicate `requireGlobal`. Either wire the middleware on `/users`, `/backup`, `/status`, `/mail-queue`, `/system-log` or delete the unused helper. |
-| **L** | `HandleAccount` / `handlers_account.go` still use the pre-1.2.3 “account” name while the route is `/settings`. |
-| **I** | Package comment on `internal/store` still says “the administrator account” after migration `0005` replaced `admin` with `users`. |
-
-**Do not:** introduce a repository layer, split the panel binary, or move
-SQLite behind an interface “for testability” — the existing fakes are enough.
-
----
-
-## 2. Complexity vs project scale
-
-The code is **not over-engineered**. A few files are large because the problem
-is large, not because of unused abstraction:
-
-| File | ~Lines | Note |
-|---|---|---|
-| `internal/health/machine.go` | 622 | Cohesive `/proc` sampler |
-| `internal/logtail/logtail.go` | 528 | Follow + rotate + reconcile + retention |
-| `internal/web/handlers/handlers_monitor.go` | 481 | Send-log UI + authz (this is where P0 lives) |
-| `internal/web/view/templates/domain_detail.html` | 476 | DNS + apps + limits + export; composition debt |
-| `internal/secretfile/secretfile.go` | ~423 | Isolated crypto envelope |
-| `internal/web/view/static/panel.css` | 749 | Tokens + layout; comment-heavy by design |
-
-Comments are long and mostly load-bearing (threat, fail-open, why not the
-obvious alternative). The cost is scanability: some files are 30–40% prose.
-That matches the project’s disclosed AI-authorship style
-([development.md](../development.md) § Authorship). Do not strip comments in
-the name of “cleanup”. Update the stale ones (see §4).
-
----
-
-## 3. Code quality
-
-Naming matches the docs (`domain` / `application`, level-1 / level-2). Errors
-on the mail path log-and-continue (intentional fail-open). Panel paths log and
-return 4xx/5xx. `crypto/rand` failure panics in `auth/token.go` — acceptable.
-
-Context is used for process lifetime and DNS timeouts, not for SQLite (correct
-with one connection). Dashboard DNS checks write distinct `rows[i]` from
-goroutines; Go 1.22+ loop semantics make that safe (`go.mod` is 1.26).
-
-Magic numbers are mostly named (`reservationTTL`, `renewThreshold`, CSP/HSTS).
-Env defaults live in `loadConfig`.
-
-| Sev | Finding |
-|---|---|
-| **M** | `sessionStore.Create` logs a DB error and still returns the token (`internal/web/auth/session.go`). Login sets the cookie; the next request bounces to `/login`. Fail closed: no cookie, error page. |
-| **M** | `app.Service.Delete` removes the registry row **before** SASL / rate-limit cleanup. SASL failure → orphaned `sasldb2` account that can still authenticate. Domain delete does SASL first (`domain/service.go`). Align app delete with that order (or compensate: restore the row on SASL failure). |
-| **L** | Login/setup `rateLimiter` sweeps expired buckets only when creating a **new** key. Many unique IPs grow the map until restart. Cap the map or sweep on a timer. |
-| **L** | `parseTrustedProxies` skips invalid CIDRs instead of refusing to start. Silent misconfiguration of `TRUSTED_PROXY_CIDR`. |
-
----
-
-## 4. Documentation completeness vs code; comments
-
-Docs are a first-class artefact (env regression test, architecture as-built,
-security accepted-risks). The drift is concentrated where **domain-admin
-shipped in 1.2.0** and several files still argue “single-user”.
-
-| Sev | Finding |
-|---|---|
-| **M** | [guide.md](../guide.md) Operations never mentions **Users** (`/users`) or the domain-admin role. Architecture and product do. An operator reading only the guide does not know the panel is multi-user. |
-| **M** | [security.md](../security.md) CSRF ADR still says the panel is single-user and “revisit if multi-user”. Multi-user shipped. The origin-check decision can stand; the **rationale and revisit trigger must be rewritten**. |
-| **M** | [security.md](../security.md) says passwords are “bcrypt (or argon2)”. Code is bcrypt only. |
-| **M** | `internal/backup` package comment claims the panel **regenerates** Postfix/OpenDKIM maps from SQLite on every start after restore. Startup only runs `CheckRestore` (`cmd/panel/main.go`). Maps/keys are **in** the tarball. Heal path is the Status **Reload** button. |
-| **L** | Architecture route table omits `/license` and the `/account` → `/settings` 308. |
-| **L** | Guide Settings section: “change the administrator username and/or password” — global Settings also has the default DMARC `rua=` address. |
-| **L** | Guide does not warn that restoring an **older** backup can resurrect sessions (architecture does). |
-| **L** | Guide rate-limiting section does not stress that level 2 is **fail-open** (store error or missing client IP → mail continues; level 1 is the backstop). |
-| **L** | [roadmap.md](../roadmap.md) and [plans/dmarc-reports.md](dmarc-reports.md) still say `admin.dmarc_report_email` after `0005` moved it to `settings`. |
-| **L** | `setupManager` comments still say “admin row”; the fact is `users` / `UserExists()`. “Plan B.1 / C.4” comments are opaque to outsiders; keep them, they are history, not errors. |
-| **I** | E2e coverage summary in development.md omits logrotate and supervisor-process checks that actually run. |
-| **I** | [plans/logrotate-mode.md](logrotate-mode.md) is **done** but still in `docs/plans/` (active-plans directory). History belongs in git / CHANGELOG. |
-
-Comments in production code are generally **high quality**. Missing comments
-are on domain-admin authorization policy in `sendLogData` (the P0 hole has no
-comment stating the intended invariant) and on `rateLimiter` memory bounds.
-
----
-
-## 5. Human readability and maintainability
-
-A new maintainer can follow the tree from [architecture.md](../architecture.md)
-into `cmd/panel` → `internal/web/web.go` → services. Tests document *why*
-(milter in-flight, queue-id anchoring, CSRF matrix).
-
-Friction:
-
-- `domain_detail.html` is the hardest HTML file to edit (repeated DNS
-  host/type/value blocks, checkbox “Edit” panels).
-- `panel.css` structure-tied selectors (`.muted + form > select:first-of-type`)
-  will break on a copy change.
-- Dual `CurrentUser` + `Principal` is redundant but works (`withPrincipal`
-  sets both).
-- `assignedDomains` loads **all** domains then filters in Go, while
-  `store.listUserDomainNames` already exists and is unused by handlers.
-
-None of this blocks maintenance at current size. Prefer small extractions
-(DNS partial, `tryAdmit`) over a layer rewrite.
-
----
-
-## 6. Logical errors
-
-### H — Domain-admin send-log list leaks other domains
-
-Detail page checks membership (`HandleDelivery`). The **list** does not.
-
-`sendLogData` in `internal/web/handlers/handlers_monitor.go`:
-
-- Empty `SendLogFilter.Domain` means “all rows” (`internal/store/sendlog.go`).
-- For a non-global user, a disallowed `?domain=` is cleared to `""`. The
-  assigned domain is filled in **only when there is exactly one**.
-- A domain-admin with **0 or ≥2** assigned domains and no (or a forged)
-  domain filter therefore sees **every** send-log row (From, To, Subject).
-- `?app=` is applied to SQL **before** it is checked against the user’s
-  application logins. The allowlist only updates the template’s selected
-  filter. Forged `?app=<foreign-login>` with an empty domain filter returns
-  that application’s rows.
-
-The deliveries table’s domain dropdown still lists only assigned domains, so
-the leak is silent.
-
-**Invariant to implement:** a non-global principal’s `QuerySendLog` /
-`CountSendLog` are always constrained to assigned domain names; if that set is
-empty, the result is empty. Validate `AppLogin` against the allowlist
-**before** the query.
-
-### M — Level-2 check/reserve race
-
-`enforceLimit` calls `flight.count` then `flight.reserve` under **separate**
-mutex acquisitions (`internal/milter/ratelimit.go`, `inflight.go`). Two MAIL
-FROM handlers can both observe `n == max-1` and both reserve. In-flight
-tracking closes the *stored-count* race (and
-`TestRateLimitCountsInFlightMessages` covers the **sequential** case). It does
-not close parallel check-then-act. Severity is tempered by fail-open and
-Postfix level-1. Fix: one `tryAdmit(key, since, max)` under the inflight
-mutex.
-
-### M — Session create fail-open
-
-See §3. Not a stolen-session bug (hash never lands in the DB); it is a
-logged-in-looking cookie that cannot be looked up.
-
-### M — App delete ordering
-
-See §3. Orphaned SASL is a mail-path consistency bug.
-
-### L — Domain export `Version` ignored on import
-
-`internal/domain/transfer.go` stamps `buildinfo.Version`; import checks format
-only. Lower risk than full-backup `CheckRestore`; still a cross-version footgun.
-
-### I — Journal milter fail-open; origin CSRF fail-open; queue-reconcile
-`bounced`
-
-Documented accepted risks in [security.md](../security.md). Not defects.
-Revisit the CSRF ADR’s *framing* (multi-user), not necessarily the mechanism.
-
----
-
-## 7. Refactoring and optimisation
-
-Worth doing, in order:
-
-1. `tryAdmit` (correctness, not speed).
-2. `SendLogFilter` domain IN-list (correctness).
-3. DNS field partial + settings credentials partial (drift).
-4. One helper for the five `panel.js` show/hide field pairs.
-5. `assignedDomains` via SQL for the current user (clarity, not performance).
-
-Not worth doing now:
-
-- Service layer for users / send-log.
-- Replacing SQLite, HTMX, or the single-container model.
-- Squashing migrations `0001`–`0005`.
-- CSRF tokens (see §12).
-- Rewriting `machine.go` or `logtail.go` for size.
-
----
-
-## 8. Licence (AGPL-3.0)
-
-Packaging is largely correct: root `LICENSE` ≡ embedded `internal/legal/LICENSE`
-(test), unauthenticated `/license`, footer copyright + Source + “No warranty”
-on login/setup, image copies `LICENSE`/`NOTICE`, Go deps are BSD-family, htmx
-is 0BSD. Network-use §13 is stated in `NOTICE` and the README.
-
-| Sev | Finding |
-|---|---|
-| **M** | IBM Plex WOFF2 files are shipped without the SIL OFL 1.1 text. OFL requires the licence to travel with the font. Add `OFL.txt` next to the fonts (and mention the path in `NOTICE`). |
-| **M** | `NOTICE` tells modifiers to change the Source URL in `layout.html`. The URL is `legal.SourceURL` in `internal/legal/legal.go`, injected by `view.go`. |
-| **L** | `/license` serves LICENSE only, not NOTICE. Optional: serve NOTICE at `/notice` or append attributions. |
-| **L** | SPDX headers only on `cmd/panel` and `cmd/selfpost-backup`. AGPL does not require per-file SPDX; either add them everywhere or drop the two so the convention is consistent. |
-| **I** | Debian package licences are pointed at packages.debian.org rather than a pinned list — normal for an image that installs from bookworm. |
-
-No AGPL-incompatible Go dependency found in `go.mod`.
-
----
-
-## 9. Legacy code and migrations
-
-| Migration | Role | Removal |
-|---|---|---|
-| `0001_init.sql` | Core schema (including historical `admin`) | Keep for all **1.x** (`PRAGMA user_version` chain) |
-| `0002_sessions.sql` | DB sessions | Keep for 1.x |
-| `0003_logtail_state.sql` | Tailer offset | Keep for 1.x |
-| `0004_dmarc_report_email.sql` | DMARC columns on `admin` | Keep for 1.x; `0005` moves the data |
-| `0005_panel_users.sql` | `users` / `user_domains`; `DROP TABLE admin` | Keep for 1.x |
-
-Squash is deferred to **2.x** — [roadmap.md](../roadmap.md) `schema-squash`.
-Until then do not delete, rename, or reorder these files. Document the 1.x
-rule in architecture § Persistence (one sentence).
-
-Compat shims to keep until a major:
-
-- `GET/POST /account` → 308 `/settings`.
-- Domain rate-limit rows may still have an unused IP list column; enforcement
-  ignores it.
-
-`sessions.username` is a string, not a `user_id` FK. Renames update the column;
-a missed rename would orphan sessions. Acceptable; a FK would be a 1.x
-migration if usernames become mutable in more places.
-
-**Delete** `docs/plans/logrotate-mode.md` once this review is the active plan
-(status `done`; history is git / CHANGELOG `[1.2.3]`).
-
----
-
-## 10. Stubs and claimed-but-unimplemented behaviour
-
-| Item | Status |
-|---|---|
-| Inbound relay | Agreed plan, **no code stubs**, no `INBOUND_RELAY_*` env. Correct. |
-| DMARC report **ingestion** | Candidate. UI copy already promises “a future release will be able to receive reports in the panel”. Settings `rua=` and DNS guidance **are** implemented. |
-| `panel-docs` | Candidate. Status blurbs were removed in 1.2.2 in favour of this item. |
-| `CONTRIBUTING.md` | Candidate, file absent. Matches roadmap. |
-| CSRF tokens | Explicitly not implemented (ADR). |
-| `auth.RequireGlobal` | Dead helper, not a feature stub. |
-
-The DMARC “future release” sentence is the only user-visible promise of
-unimplemented behaviour. Soften it to “SelfPost does not receive inbound mail”
-or keep it and treat `dmarc-reports` as the fulfilment — product call, Sonnet
-copy.
-
----
-
-## 11. GUI: hacks and layout composition
-
-The panel is CSP-strict (no inline script/style; `TestNoTemplateUsesInlineScriptOrStyle`).
-No `!important`. Progressive enhancement is real (pages work without JS).
-Adaptive polling in `panel.js` is a **documented** workaround: HTMX
-`hx-trigger="every Ns [expr]"` uses `new Function`, which CSP would break.
-
-| Sev | Finding |
-|---|---|
-| **M** | `RateLimitErr` uses `class="flash error"`. `.flash` is the **success** surface; `.error` only recolors text. There is no `.flash.error` rule. Validation failures look like success (red text on green). `domain_detail.html` + `panel.css`. |
-| **M** | User **Delete** has no `data-confirm` and no confirm page. App delete / regen / rate-limit clear do; domain delete has `domain_delete.html`. One mis-click removes a panel user. |
-| **M** | `domain_detail.html` repeats Host/Type/Value/`code-row` for DNS status **and** publishable records. Extract a partial (same pattern as `encrypt_fields.html`). |
-| **M** | `settings.html` duplicates the credentials form (global split vs domain-admin narrow card). Drift already visible in the muted help text. |
-| **L** | Adaptive polling: `outerHTML` swap every 5 s can steal clicks / focus; poll failures retry silently. Consider `aria-live="polite"` and a visible retry/error. Do not switch back to `hx-trigger="every"` under this CSP. |
-| **L** | Checkbox-driven Edit panels instead of `<details>` (commented in the template). Works without JS; no `aria-expanded`. |
-| **L** | Five near-identical show/hide helpers in `panel.js`. Encrypt/import fields can flash visible before `DOMContentLoaded`. |
-| **L** | `hx-get` query params in `deliveries_rows.html` are not `urlquery`-encoded. Safe while domain/app charset is locked down. |
-| **L** | Applications on a domain page are unpaginated. Fine until an operator has dozens of apps. |
-| **L** | `<label>` used as a heading on DNS/status readouts (no `for`). |
-| **I** | `{{define "wide"}}` override and `main:has(> .card.narrow)` are non-obvious but tested. Keep; do not “simplify” into per-page CSS files. |
-
-`data-confirm` is skipped when JS is off (documented in `panel.js` only).
-Domain delete already uses a real page; user delete should follow that
-pattern or at least get `data-confirm`.
-
----
-
-## 12. Weakly documented disputed decisions
-
-These are real choices. Several are in [security.md](../security.md); the
-problem is **stale framing** after domain-admin, not silence.
-
-| Decision | Where | Gap |
-|---|---|---|
-| CSRF via origin / `Sec-Fetch-Site`; no tokens; POST with neither header allowed | security.md ADR | Still argued as “single-user”. Revisit trigger already fired. **Rewrite the ADR**; implementing tokens is a separate product call. |
-| Journal-milter fail-open | architecture, milter comments | Guide rate-limit section should say L2 is best-effort. |
-| Unencrypted backup/export by default | security.md | OK. Domain-admin can **export working SASL passwords** for assigned domains (`HandleExportDomain` uses `lookupDomain`). Guide/security should say so. |
-| Queue reconcile marks lost lines `bounced` | security.md | OK. |
-| Sliding session, no absolute cap; HTMX GET does not renew | architecture, guide | OK. |
-| Restore can resurrect sessions from an older backup | architecture | Missing from the operator guide. |
-| L2 skipped when client IP is unknown | milter + unit test | Not in the guide. |
-| Backup encryption optional | security.md | OK. |
-| Supervisord socket `0770` so the panel can `postfix reload` | supervisord.conf | Compromised panel ≈ mail-stack control. Documented as intentional; keep. |
-| `workflow_dispatch` on `release.yml` derives version from `GITHUB_REF_NAME` | `.github/workflows/release.yml` | A manual run from `main` can publish a non-semver tag. Guard: only `vX.Y.Z` or an explicit version input. |
-
----
-
-## 13. Edge cases
-
-Covered above: 0 / 1 / ≥2 assigned domains on the send log; forged
-`domain`/`app` query params; empty allowlist must not mean “all”.
-
-Others:
-
-- **Last global administrator** cannot be demoted/deleted (UI + server). Good.
-- **Domain-admin with no domains** (all assigned domains deleted →
-  `user_domains` cascade): today they see the full send log (P0). After the
-  fix they should see an empty log, not an error.
-- **Missing `mail.log`** after rotation: treated as empty, not an error
-  (tested). Good.
-- **Backup download after headers committed**: truncated file possible
-  (streaming trade-off). Encrypted domain export is sealed in memory first.
-  Acceptable; do not buffer full backups.
-- **`parsePage`**: huge `p` yields a large offset and an empty page, not a
-  500. Fine.
-- **Concurrent domain DNS on the dashboard**: safe under Go 1.22+.
-- **Import domain** is global-only; **export** is any principal who can
-  access the domain. Intentional once documented.
-
----
-
-## 14. Tests
-
-**Strengths.** Milter L2 + in-flight, DNS grading, logtail follow/rotate/
-reconcile, secretfile tamper, SASL argv hygiene (`--` before login), template
-CSP/nav/legal footer, env-key ↔ guide regression, e2e mail path (AUTH, DKIM,
-queued→sent, L1/L2, fail-open, hostname gate, session vs restart). Test
-comments are better than average.
-
-**Documented?** How to run tests: [development.md](../development.md) §
-Testing. There is no e2e README (package comment in `test/e2e/main_test.go`
-is the stand-in). Individual tests are not inventoried in docs — that is
-fine; the e2e **summary** should mention logrotate.
-
-**Gaps (high value):**
-
-| Area | Gap |
-|---|---|
-| RBAC | **No** tests for `authz.go`, `CanAccessDomain`, domain-admin send-log scoping, `/users` 404 for domain-admin, backup 404. This is why P0 shipped. |
-| Auth HTTP | No `HandleLogin` / `HandleSetup` tests (TTL, constant-time, setup complete → 404). No tests for `auth/ratelimit.go` `Allow`. |
-| Sessions store | No `store/sessions*_test.go` (covered only via `auth_test` wrappers). |
-| Backup as operator path | Create + `CheckRestore` unit-tested; **no** extract-onto-`/data`-and-boot test; panel `HandleBackup` POST untested. |
-| Handlers | No tests for users CRUD, domain add/delete, account POST, DNS recheck endpoints. |
-| `postfix.Queue` | Parser only; exec path untested (e2e does not open Mail queue). |
-
-**Weak / low-value (keep, do not grow this style):**
-
-- `TestDecryptErrorMessage` — substring mapping.
-- `TestBackupPageOffersEncryption` — `strings.Contains` over HTML.
-- Many `templates_test.go` cases — structural guards (CSP, nav). Valuable as
-  guards, not as behaviour tests.
-- E2e `testNoAuthRejected` vs `testForeignRelayRejected` — nearly the same
-  unauthenticated send.
-
-**E2e hygiene:**
-
-- Fatal string in `testLevel1RateLimit` says `RATE_LIMIT_MESSAGES_PER_IP=5`;
-  override is `50` (`test/e2e/negative_test.go` vs `compose.override.yml`).
-- `coredns/coredns:latest` is unpinned.
-- `TestImageBuildPreservesLogrotateMode` chmods the source conf then rebuilds
-  — can race a dirty tree.
-
-Do not add snapshot tests of entire pages. Add **authorization** tests that
-would have caught P0.

-
-## 15. Duplication and local patches
-
-| Local patch | Systemic fix |
-|---|---|
-| Send-log domain/app allowlist after/around the query | Store filter: `Domains []string` required for non-global; validate app login first |
-| `assignedDomains` loads all domains | Use `listUserDomainNames` / `ListDomainsForUser` |
-| `requireGlobal` on each handler | Optional: `auth.RequireGlobal` on those muxes |
-| Five JS field-sync helpers | One `data-show-when` helper |
-| DNS host/type/value markup × many | Template partial |
-| Settings credentials form × 2 | Partial |
-| `web/validate` vs `app/validate` | Keep separate (different alphabets); do not merge |
-
-The send-log allowlist is the textbook “local patch instead of a store
-invariant”.
-
----
-
-## 16. Other improvements
-
-- Pin CoreDNS in e2e.
-- Guard `release.yml` `workflow_dispatch` versioning (**Opus**, infra).
-- Optional: `Resync` once after a successful `CheckRestore` (heal drifted
-  maps). Small, mail-path, **Opus**. Not required if the tarball is the
-  restore story — but then **fix the backup package comment**.
-- Optional: serve `NOTICE` next to `/license`.
-- Do not start inbound-relay until P0 is closed.
-
----
-
-## Implementation checklist
-
-Work top to bottom. Commit per phase (or per coherent sub-step) when asked.
-Update [CHANGELOG.md](../../CHANGELOG.md) `[Unreleased]` with each user-visible
-change. After Go changes: `go build`, `go vet`, `go test ./...`.
-
-### P0 — Domain-admin send-log authorization (defect)
-
-**Model: Opus.** Tests in the same change. **Fable** on the diff after it
-lands (reviewer ≠ author).
-
-- [x] Extend `SendLogFilter` so a non-empty domain list is an `IN` constraint.
-      Empty list for a non-global user → zero rows, not “all”. Done as
-      `Domains` + `AllDomains`: the zero value matches nothing, so a caller
-      that states no scope cannot read the journal.
-- [x] `sendLogData`: for `!p.IsGlobal()`, always constrain to assigned domain
-      names; validate `AppLogin` against the user’s apps **before** query.
-- [x] Tests: domain-admin with 0, 1, and 2 assigned domains; unfiltered list;
-      forged `?domain=` and `?app=`; detail page still 404s on a foreign id
-      (already true — keep a regression test).
-- [x] Comment the invariant next to `sendLogData` (the comment that was
-      missing).
-
-**Done when:** a domain-admin cannot read another domain’s send-log rows via
-the list, the fragment, or query parameters. `go test ./...` green.
-
-### P1 — Fail-closed consistency (mail path / auth)
-
-**Model: Opus.**
-
-- [x] `inflight.tryAdmit` (count + reserve under one lock). Extend milter
-      tests with overlapping `MailFrom` (true concurrency, not sequential).
-      Two tests: concurrent `MailFrom` sessions gated so they all read the
-      stored count before anyone reserves (exactly one admitted), and a
-      saturation test on `tryAdmit` that overshoots the ceiling whenever count
-      and reserve are separate critical sections.
-- [x] `sessionStore.Create` returns an error; login does not set a cookie on
-      failure.
-- [x] `app.Service.Delete`: SASL (and rate-limit row) before or compensating
-      with the registry row; match domain-delete ordering. Test the failure
-      path with a fake SASL that errors.
-
-**Done when:** unit tests cover the race and the two fail-closed paths.
-
-### P2 — Security/operator docs that are wrong today
-
-**Model: Sonnet** (English docs). No code behaviour change except copy.
-
-- [x] Rewrite the CSRF ADR in [security.md](../security.md) for a panel that
-      already has global + domain-admin. Keep the origin-check mechanism
-      unless a new decision says otherwise. New revisit trigger (e.g. untrusted
-      domain-admins, or a requirement that does not depend on browser
-      headers).
-- [x] Drop “or argon2” unless argon2 is implemented.
-- [x] [guide.md](../guide.md): Users / roles; Settings DMARC field; L2
-      fail-open; restore can resurrect sessions; domain-admin can export
-      working SASL passwords for assigned domains.
-- [x] Architecture route table: `/license`, `/account` → `/settings`.
-- [x] Fix `internal/backup` package comment (restore = extract tarball +
-      `CheckRestore`; maps come from the archive; Reload heals drift).
-- [x] `admin.dmarc_report_email` → `settings` in roadmap + dmarc-reports plan.
-- [x] development.md e2e summary: logrotate + process checks.
-- [x] `setupManager` / `store` package comments: `users`, not `admin` row.
-
-**Done when:** an operator who reads only the guide knows the panel has two
-roles, and security.md no longer calls the panel single-user.
-
-### P3 — GUI defects from the 1.2.x layout pass
-
-**Model: Sonnet.**
-
-- [ ] `.flash.error` (or stop using `.flash` for `RateLimitErr`) — danger
-      surface, not success.
-- [ ] User delete: `data-confirm` at minimum; prefer a confirm page like
-      domain delete.
-- [ ] DNS field partial; settings credentials partial.
-- [ ] Optional: `urlquery` on deliveries fragment params; `aria-live` on
-      polled regions; confirm-without-JS note next to the CSRF accepted risks.
-
-**Done when:** a rate-limit validation error is visually an error; user delete
-cannot be a single unmarked click.
-
-### P4 — Tests and e2e hygiene
-
-**Model: Opus** for auth/RBAC/limiter tests; **Haiku** for the L1 fatal-string
-typo; **Sonnet** if e2e docs need a paragraph.
-
-- [ ] `auth/ratelimit.go` unit tests (window, lockout, sweep).
-- [ ] Login/setup handler tests (happy path + lockout + setup expiry).
-- [ ] Domain-admin 404 on `/users`, `/backup`, `/mail-queue`, `/system-log`,
-      `/status` (if not already implied by P0 tests).
-- [ ] Fix e2e L1 fatal string (`50`, not `5`).
-- [ ] Pin `coredns` image digest or a major version.
-- [ ] Optional later: backup extract + `CheckRestore` + panel boot (heavy;
-      e2e or integration). Not a P4 blocker.
-
-**Done when:** P0 cannot regress without a red test; e2e L1 message matches
-the override.
-
-### P5 — Licence and release infra
-
-**Model: Sonnet** for OFL/NOTICE prose; **Opus** for `release.yml`; **Haiku**
-for SPDX consistency and deleting the done logrotate plan.
-
-- [ ] Add SIL OFL 1.1 text beside the Plex WOFF2 files; point `NOTICE` at it.
-- [ ] `NOTICE` Source URL instructions → `internal/legal/legal.go`.
-- [ ] `release.yml`: `workflow_dispatch` must not publish `main` as a version
-      (require `vX.Y.Z` or an explicit `version` input that matches SemVer).
-- [ ] Delete [plans/logrotate-mode.md](logrotate-mode.md) (done; git keeps it).
-- [ ] Decide SPDX-everywhere vs SPDX-nowhere; do not leave two files special
-      without a one-line note in development.md.
-
-**Done when:** OFL travels with the fonts; a dispatch from `main` cannot tag
-`ghcr.io/...:main`.
-
-### P6 — Optional cleanup (do not start until P0–P3 are done)
-
-**Model: Sonnet** unless noted.
-
-- [ ] Use `auth.RequireGlobal` or delete it (**Haiku** if delete).
-- [ ] Rename `handlers_account.go` / `HandleAccount` to settings (**Haiku**).
-- [ ] `ListDomainsForUser` instead of load-all-and-filter.
-- [ ] Cap or periodically sweep the login limiter map (**Opus**, small).
-- [ ] Collapse `panel.js` field-sync helpers.
-- [ ] Soften or keep DMARC “future release” UI copy (product call).
-- [ ] Optional startup `Resync` after restore (**Opus**). Only if P2’s comment
-      fix is judged insufficient.
-
-### P7 — Security review of the P0–P1 diff
-
-**Model: Fable.** Not authorship.
-
-- [ ] Review the send-log authz change, `tryAdmit`, session create, and app
-      delete ordering against [security.md](../security.md). Close each finding
-      with a fix or an accepted-risk entry.
-
----
-
-## What not to do
-
-- Do not squash SQLite migrations in **1.x** (see roadmap `schema-squash` for 2.x).
-- Do not implement inbound-relay, DMARC ingestion, or in-panel docs as part of
-  this plan.
-- Do not add CSRF tokens in the same breath as rewriting the ADR. Tokens are a
-  new decision.
-- Do not “simplify” comments that record threat models.
-- Do not introduce a general service/repository layer for users.
-
----
-
-## Done when (this plan)
-
-1. P0 is shipped and covered by tests.
-2. P2 has removed “single-user” from the CSRF ADR and documented Users in the
-   operator guide.
-3. P3 flash/delete bugs are gone.
-4. P7 has run on the P0–P1 diff.
-5. This file’s remaining boxes are either checked or explicitly dropped in
-   [roadmap.md](../roadmap.md) with a reason.
-6. [CHANGELOG.md](../../CHANGELOG.md) `[Unreleased]` lists the user-visible
-   items (authz, docs, GUI).
-
-After that, delete this plan (history in git) and return the recommended
-order on the roadmap to inbound-relay.

+# Plan: domain-stats-auto-ratelimit
+
+**Status:** candidate  
+**Date:** 2026-08-17  
+**Version:** `1.x` MINOR; migrations must stay compatible with `1.0.0`.
+
+---
+
+## Goal
+
+Give the operator **30-day sending statistics** per domain and per application
+(total volume, peak and average rate), and an optional **auto** level-2 rate
+limit that sets `max_messages` from the average rate (avg × multiplier) over the
+level-1 window.
+
+## Scope
+
+**In:**
+
+- Rolling **30-day** stats on each domain page (domain aggregate + per-app rows):
+  message count, peak msg/h, average msg/h.
+- Level-2 rate limit mode **manual** (today) or **auto** for domain and
+  application scopes.
+- Auto formula: `max_messages = ceil(avg_hourly × multiplier)`, window =
+  level-1 window (`RATE_LIMIT_WINDOW_SECONDS`); capped at level 1.
+- Background recalculation (e.g. every 6 h, alongside send-log prune); milter
+  reads stored `max_messages` / `window_seconds` only (no aggregates on the
+  hot path).
+- Panel UI: stats card, manual/auto toggle, multiplier field, read-only computed
+  limit in auto mode, optional «Recalculate now».
+- RBAC: domain-admin sees stats and may configure auto/manual for assigned
+  domains only; same authz as existing rate-limit handlers.
+- Tests, [guide.md](../guide.md), [CHANGELOG.md](../../CHANGELOG.md); security
+  review (Fable) for rate-limit path changes.
+
+**Out:**
+
+- Changing level 1 (Postfix env) — auto only fills level 2 under the L1 cap.
+- Automated IP warmup schedules ([guide.md](../guide.md) § IP warmup stays
+  operator-driven).
+- Prometheus/Grafana, alerting, APIs.
+- Counting level-1 refusals or `rejected` rows as sent volume.
+- Per-client-IP analytics.
+
+## Data source
+
+All metrics come from SQLite `send_log`, same rules as
+[`CountMessages`](../../internal/store/ratelimits.go):
+
+- One message = one distinct `queue_id` (many recipients = one count).
+- `status != rejected` (level-2 refusals never queued).
+- Level-1 refusals are **not** in `send_log` — stats under-count refusals;
+  document in UI copy.
+
+Retention today is env `SEND_LOG_RETENTION_DAYS` (default 90). Stats use the
+last **30 days** of rows still present. If retention < 30 days (after
+[send-log-retention](send-log-retention.md)), the stats window is
+`min(30, retention)` with a warning.
+
+### Metrics
+
+| Metric | Definition |
+|---|---|
+| **total** | `COUNT(DISTINCT queue_id)` in the stats window |
+| **peak rate** | maximum messages in any **hourly** bucket in that window (msg/h) |
+| **avg rate** | `total / hours_in_window`, where `hours_in_window = min(720, age of domain/app in hours, retention hours)` |
+
+Keys: `send_log.domain` (domain scope), `send_log.app_login` (application scope).
+
+## Architecture
+
+```mermaid
+flowchart LR
+  milter["journal-milter"] --> sendLog["send_log"]
+  sendLog --> statsQuery["StatsQuery 30d"]
+  statsQuery --> domainPage["domain page stats card"]
+  statsQuery --> autoJob["auto recalc job"]
+  autoJob --> rateLimits["rate_limits"]
+  rateLimits --> milter
+```
+
+1. **[`internal/store/stats.go`](../../internal/store/stats.go)** — `SendStats`
+   with `Total`, `PeakPerHour`, `AvgPerHour`; `DomainSendStats(name, since)` /
+   `AppSendStats(login, since)`.
+2. Hourly buckets: `strftime('%Y-%m-%d %H', created_at)` + `GROUP BY`; subquery
+   for peak; total via distinct `queue_id`.
+3. Indexes `idx_send_log_domain` and `idx_send_log_created_at` exist; add
+   composite `(domain, created_at)` only if profiling shows need.
+4. **Auto recalc** — panel goroutine (same interval as send-log prune): for each
+   `rate_limits` row with `mode = auto`, recompute `max_messages`, set
+   `auto_updated_at`. Milter unchanged except reading new columns via existing
+   `RateLimit` lookup.
+
+### Auto rate limit
+
+Extend [`RateLimit`](../../internal/store/ratelimits.go):
+
+```go
+type RateLimit struct {
+    // existing: Scope, RefID, AllowedIPs, MaxMessages, WindowSeconds
+    Mode           string  // "manual" | "auto"
+    AutoMultiplier float64 // default 2.5 when Mode == "auto"
+    AutoUpdatedAt  time.Time
+}
+```
+
+**Formula:**
+
+```
+avg_hourly = total_messages_in_window / hours_in_window
+max_messages = ceil(avg_hourly * auto_multiplier)
+window_seconds = L1 window (not editable in auto mode)
+max_messages = min(max_messages, L1 max)
+```
+
+When `total == 0`: auto limit stays **inactive** (same as empty manual limit);
+UI explains that traffic is required before auto can apply.
+
+**Application overrides** ([`handlers_ratelimit.go`](../../internal/web/handlers/handlers_ratelimit.go)):
+
+- Trusted IPs required.
+- Auto app ceiling **strictly above** domain limit when domain limit is active.
+- Ceiling ≤ L1.
+
+**Fail-open:** store errors during recalc must not weaken enforcement of the
+last successfully written limit; recalc failures are logged only.
+
+### Migration (`0006_rate_limit_auto.sql`)
+
+```sql
+ALTER TABLE rate_limits ADD COLUMN mode TEXT NOT NULL DEFAULT 'manual'
+  CHECK (mode IN ('manual', 'auto'));
+ALTER TABLE rate_limits ADD COLUMN auto_multiplier REAL;
+ALTER TABLE rate_limits ADD COLUMN auto_updated_at TEXT;
+```
+
+Existing rows → `manual`.
+
+### Domain export
+
+Today rate limits are **not** exported. This plan adds them (including
+`mode`, `auto_multiplier`) to domain transfer JSON — document as a boundary
+change in [guide.md](../guide.md) § Export.
+
+## Panel UI
+
+- Domain page ([`domain_detail.html`](../../internal/web/view/templates/domain_detail.html)):
+  - **Sending statistics (30 days)** — total, peak msg/h, avg msg/h.
+  - Per-application stats in the app list.
+  - Rate limit: Manual / Auto, multiplier (e.g. 1.5–5.0, default 2.5), read-only
+    computed max/window in auto mode, «Recalculate now».
+- Optional later: «30d» column on domain list (global admin only).
+
+## Tests
+
+- `internal/store/stats_test.go` — fixtures → total / peak / avg.
+- `internal/store/ratelimits_test.go` — auto recalc, L1 cap, app > domain.
+- Handler tests — auto form validation, multiplier bounds.
+- Milter tests — enforced limit matches last recalculated values.
+
+`go test` / `go vet` on touched packages.
+
+## Done when
+
+- Domain and app 30-day stats visible on the domain page; domain-admin scoping
+  enforced.
+- Manual/auto toggle works for domain and app; auto recalc updates `rate_limits`
+  and milter enforces stored ceilings.
+- Zero-traffic auto stays inactive with clear UI copy.
+- [guide.md](../guide.md) and [CHANGELOG.md](../../CHANGELOG.md) updated;
+  security review passed.
+
+## Risks
+
+- Heavy aggregation on large `send_log` tables — mitigate with indexes or
+  nightly rollups (phase 2).
+- Stats without level-1 visibility — mitigate with operator-facing caveat.
+- Auto limit too tight after a spike — multiplier is operator-tuned; show peak
+  alongside avg in auto UI.
+
+## Dependencies
+
+- [`send-log-retention`](send-log-retention.md) is a separate roadmap item but
+  should land before or in parallel so operators can set retention ≥ 30 days
+  from the panel.

-# Plan: logrotate-mode (mail.log stops rotating in some images)
-
-**Status:** done  
-**Version:** patch; no schema, no configuration surface.
-
----
-
-## Summary
-
-`mail.log` stopped rotating when `/etc/logrotate.d/mail` landed in the image
-with group/other write permission (e.g. build context from a Windows tar sync).
-logrotate ignores such configs but exits 0, so the loop looked healthy while
-the log grew without bound.
-
-## What shipped
-
-- [`build/Dockerfile`](../../build/Dockerfile): `COPY --chmod` pins config
-  (`0644`) and script (`0755`) modes so the image no longer depends on checkout
-  file modes.
-- [`build/logrotate-loop.sh`](../../build/logrotate-loop.sh): preflight and
-  per-iteration checks refuse group/other-writable configs; logrotate stderr
-  mentioning `Ignoring` is fatal.
-- [`test/e2e/logrotate_check.go`](../../test/e2e/logrotate_check.go): asserts
-  mode `644`, forced `logrotate -f`, and that a group-writable context file
-  still produces `644` in the image.
-
-`create 0640 postfix selfpost` in [`build/logrotate-mail.conf`](../../build/logrotate-mail.conf)

+# Plan: queue-retries (Postfix retry policy in the panel)
+
+**Status:** agreed  
+**Date:** 2026-08-13  
+**Version:** patch; no schema, no configuration surface.  
+**Order:** small panel item; does not wait on inbound-relay.
+
+---
+
+## Goal
+
+Show the operator how Postfix retries deferred mail: first retry delay, later
+backoff cap, and how long a message stays in the queue before it bounces. The
+numbers come from this container's effective Postfix config, not from
+hard-coded copy.
+
+## Scope
+
+**In:**
+
+- A static «How delivery retries work» card on `/mail-queue` (global
+  administrator). Not inside the HTMX poll fragment — the snapshot is taken at
+  panel start.
+- The same human-readable intervals in `/deliveries/{id}` history for
+  `deferred` and `bounced` (domain administrators never see Mail queue).
+- Operator docs: [guide.md](../guide.md) Mail queue bullet;
+  [architecture.md](../architecture.md) notes the one-shot `postconf -h` at
+  panel start. [CHANGELOG.md](../../CHANGELOG.md) `### Added`.
+
+**Out:**
+
+- Changing Postfix retry parameters, or exposing them as panel settings
+  ([product.md](../product.md): Postfix is used as-is).
+- An `attempts` column on `send_log`, or «attempt 3 of N» — Postfix has no
+  attempt budget; it is time-based.
+- Counting `status=deferred` lines in `mail.log` or reading `postcat`. Each
+  attempt is already on the delivery page's log table; the journal stores only
+  the last status.
+- Duplicating the card on Status (summary + link to Mail queue already exist).
+- Re-reading `postconf` on every HTTP request.
+
+## Architecture
+
+Acceptance is still synchronous SMTP. Delivery stays in Postfix's on-disk
+queue. SelfPost does not enqueue, retry, or deliver.
+
+```mermaid
+flowchart LR
+  smtpAccept["SMTP 250 accepted"] --> postfixQueue["Postfix queue"]
+  postfixQueue -->|"deferred: backoff until queue lifetime"| retry["Retry MX"]
+  retry -->|sent| done["sent"]
+  retry -->|lifetime elapsed or 5xx| bounce["bounced"]
+  postfixQueue --> mailQueuePage["/mail-queue policy card"]
+  postfixQueue --> deliveryPage["/deliveries/id history copy"]
+```
+
+[build/postfix-config.sh](../../build/postfix-config.sh) does not set
+`queue_run_delay`, `minimal_backoff_time`, `maximal_backoff_time`,
+`maximal_queue_lifetime`, `bounce_queue_lifetime`, or `delay_warning_time`.
+Debian/Postfix 3.x compiled-in defaults therefore apply unless the operator
+overrides them (`postconf -e` inside the container).
+
+### Loading the numbers
+
+Once, when the HTTP role starts ([cmd/panel/httpserver.go](../../cmd/panel/httpserver.go),
+after `postfix-config.sh` has run):
+
+```
+postconf -h queue_run_delay minimal_backoff_time maximal_backoff_time maximal_queue_lifetime bounce_queue_lifetime delay_warning_time
+```
+
+`postconf -h`, not a parse of `/etc/postfix/main.cf`: stock values are not
+written to the file. `postconf` is the effective config, including a manual
+override.
+
+- Fixed argv, no user input — same pattern as
+  [postfix.Queue](../../internal/postfix/queue.go) /
+  [security.md](../security.md).
+- Cache on `handlers.Config` (via `web.Config`). The HTMX fragment does not
+  call `postconf`.
+- A live `postconf -e` is visible after the next panel (or container) restart.
+  While the process is up, the panel shows the start-up snapshot.
+- Parse Postfix time units (`300s`, `5d`, `1h`, a bare number is seconds) in
+  `internal/postfix`. Format human strings (`5 minutes`, `5 days`,
+  `about 1 hour 7 minutes`) in one place so the Mail queue card and
+  `deliveryEvents` cannot drift.
+- If `postconf` is missing (unit tests on Windows, binary outside the
+  container): log a warning, fall back to Postfix 3.x compiled-in defaults
+  (`300s` / `4000s` / `5d` / `0`), and put a muted note on the card. Tests
+  stub the lookup (as `queueIDs` in the log-tailer) or pass a fixture on
+  `Config`. Do not fail panel start.
+
+Typical stock values, for orientation only — the UI prints whatever
+`postconf` returned:
+
+| Parameter | Stock | Meaning |
+|---|---|---|
+| `queue_run_delay` / `minimal_backoff_time` | `300s` | First retry and deferred-queue scan |
+| `maximal_backoff_time` | `4000s` | Cap on the doubling gap (~1 h 7 min) |
+| `maximal_queue_lifetime` | `5d` | Then bounce |
+| `delay_warning_time` | `0` | No delay warning to the sender |
+
+## Panel copy
+
+Mail queue card facts: first retry; later retries (doubling, capped);
+kept in queue; then bounced. Short prose: there is no fixed attempt count; a
+`deferred` message stays in this listing until it is delivered or the queue
+lifetime runs out.
+
+`deliveryEvents(row, policy)`:
+
+- `deferred`: retries, first after X, then with increasing gaps up to Y, for
+  up to Z.
+- `bounced`: or Postfix gave up after Z in the queue.
+
+## Tests
+
+- Duration parser: `5d`, `300s`, `4000s`, `1h`, `0`, bare number.
+- `/mail-queue` handler: card shows the fixture policy's human strings, not a
+  live `postconf`.
+- Delivery page / `deliveryEvents`: `deferred` and `bounced` contain those
+  strings ([handlers_monitor_test.go](../../internal/web/handlers/handlers_monitor_test.go)).
+- [templates_test.go](../../internal/web/view/templates_test.go): pass the new
+  fields if rendering `mail_queue` requires them.
+
+`go test` / `go vet` on the touched packages.
+
+## Done when
+
+- `/mail-queue` states this Postfix's first retry, backoff cap, and queue
+  lifetime.
+- A `deferred` / `bounced` delivery page uses the same intervals.
+- A manual `postconf -e maximal_queue_lifetime=2d` followed by a panel restart
+  changes what the panel prints.
+- Guide and architecture describe the snapshot; CHANGELOG has an Added entry.
+
+## Risks
+
+- Showing compiled-in fallbacks when `postconf` failed would mislead if the
+  operator had overridden them — mitigate with the muted note on the card.
+- Inventing a max-attempt count would be false; the copy must stay time-based.

+# Plan: send-log-retention
+
+**Status:** candidate  
+**Date:** 2026-08-17  
+**Version:** `1.x` MINOR; no schema migration required (uses existing `settings` table).
+
+---
+
+## Goal
+
+Let the **global administrator** change how long delivery journal rows
+(`send_log`, `/deliveries`) are kept, from the panel — without editing `.env`.
+
+## Context (as-built)
+
+Retention **already exists**, but only via environment:
+
+- `SEND_LOG_RETENTION_DAYS` (default **90**) in `.env` / Compose.
+- [`cmd/panel/main.go`](../../cmd/panel/main.go) passes it to
+  [`logtail.Run`](../../internal/logtail/logtail.go).
+- [`retentionLoop`](../../internal/logtail/logtail.go) prunes via
+  [`DeleteSendLogBefore`](../../internal/store/sendlog.go) every **6 hours**.
+- No panel control; [`handlers_monitor.go`](../../internal/web/handlers/handlers_monitor.go)
+  hardcodes «ninety days» in copy.
+- Migration `0001_init.sql` describes `settings` as the place for «retention
+  overrides», but no UI writes that key yet.
+
+This plan moves the **effective** retention into SQLite `settings`, with env as
+bootstrap only.
+
+## Scope
+
+**In:**
+
+- Settings card on `/settings` (global administrator only): **Send log
+  retention (days)**.
+- Key `send_log_retention_days` in [`settings`](../../internal/store/settings.go).
+- Validation: integer range **7–365** (exact bounds fixed at implementation).
+- On first use: if setting missing, seed from env
+  (`SEND_LOG_RETENTION_DAYS`, default 90) at panel start or first save.
+- Log-tailer reads the setting **each prune cycle** (no container restart).
+- Delivery pages and guide copy show the **current** retention, not a hardcoded
+  90.
+- Tests; [guide.md](../guide.md); [CHANGELOG.md](../../CHANGELOG.md).
+
+**Out:**
+
+- Per-domain retention (instance-wide only).
+- `mail.log` rotation (logrotate, 14 daily files — unchanged).
+- Immediate prune on save when lowering retention (next 6 h cycle is enough;
+  optional «Prune now» not in v1).
+- Domain-admin access to this setting.
+
+## Architecture
+
+```mermaid
+flowchart LR
+  settingsPage["/settings form"] --> sqlite["settings.send_log_retention_days"]
+  env["SEND_LOG_RETENTION_DAYS bootstrap"] --> sqlite
+  sqlite --> retentionLoop["logtail retentionLoop"]
+  retentionLoop --> prune["DeleteSendLogBefore"]
+```
+
+1. **Read path** — `GetSendLogRetentionDays()`: settings value if valid, else env
+   default.
+2. **Write path** — POST `/settings` (global admin): validate, `SetSetting`,
+   flash confirmation.
+3. **Prune path** — change [`logtail.retentionLoop`](../../internal/logtail/logtail.go)
+   to accept `func() int` or `RetentionReader` that queries settings each cycle
+   (same 6 h ticker).
+4. **Copy** — inject retention days into delivery list/detail templates and
+   remove hardcoded «ninety days».
+
+`SEND_LOG_RETENTION_DAYS` remains documented in [guide.md](../guide.md) as the
+**initial default** until changed in Settings.
+
+## Relation to domain-stats-auto-ratelimit
+
+[domain-stats-auto-ratelimit](domain-stats-auto-ratelimit.md) uses a **30-day**
+stats window. Requires effective retention ≥ 30 for full accuracy. When
+retention < 30:
+
+- Stats UI shows a warning and uses `min(30, retention)` as the window, or
+- Settings validation warns when saving a value below 30 while stats/auto are
+  enabled (pick one at implementation; document in guide).
+
+Recommended roadmap order: **send-log-retention** before or parallel with
+domain-stats-auto-ratelimit.
+
+## Panel UI
+
+New card on [`settings.html`](../../internal/web/view/templates/settings.html)
+(global admin block, near rate limits or under a «Deliveries» heading):
+
+- Number input: retention days (7–365).
+- Muted copy: rows older than this are deleted from `/deliveries`; main driver
+  of `/data` growth; does not affect `mail.log` rotation.
+
+Domain administrators keep the narrow credentials-only settings page.
+
+## Tests

+
+## Done when
+
+- Global admin can set retention on `/settings`; value persists in SQLite.
+- Prune uses the panel value on the next cycle; env remains bootstrap default.
+- Guide documents panel vs env; CHANGELOG entry added.
