+Source of truth: [docs/assets/panel-ui/system.html](docs/assets/panel-ui/system.html) and `system.css`.
+
+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.

 ### 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.

+- 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

 ### 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,

+- 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

+  <p>Проект системы — как собирать экраны, чтобы не чинить пустые колонки, высоту полей и ряды кнопок по одному. Каждый экран — отдельная страница, не простыня с якорями. Знак и палитра из листа утверждения не меняются. HTML в <code>docs/assets/panel-ui/</code>, не вёрстка <code>internal/web</code>.</p>

+  <h2>Система, не рескин</h2>
+  <p>Первый click-through повторил сетку живой панели, поэтому те же сбои чинились по одному. <a href="system.html">Грамматика</a> задаёт регионы (<code>measure</code> / <code>pair</code> / <code>fill</code>), карточку со слотом справки, <code>field-row</code> (Host и Type одной высоты) и <code>actions-row</code>. Макеты собраны только из этого: один экран — один HTML-файл.</p>

+
+<section>
+  <h2>Ширина окна</h2>
+  <p>Сейчас оболочка центрируется, колонка контента упирается в <code>64rem</code>, формы ещё уже — <code>48rem</code>. На широком мониторе поля пустые. Растянуть поля на 100% окна нельзя — они становятся нечитаемыми. Две независимые карточки рядом — можно.</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
+publishing — Actions reads that repo, not Gitea.
+
+**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
+   per-arch GHCR cleanup — every mirror (re)push of that tag can republish
+   `1.0.0-amd64` / `1.0.0-arm64`. Tags from `v1.3.0` onward only run
+   `release.yml` on **Publish release** (`release: published`), so mirroring
+   those tags alone does not start the image build.
+
+   Safe mirror: push tags to GitHub without deleting existing ones; keep release
+   tags on Gitea; publish the GitHub Release on github.com after the mirror has
+   the tag.

+# 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: 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
+
+- Save/load setting; reject out-of-range values.
+- `retentionLoop` uses updated value without process restart (mock reader).
+- Bootstrap: empty settings → env default used for prune.
+- Template/delivery copy reflects configured days.
+
+`go test` / `go vet` on touched packages.
+
+## 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.
+- Hardcoded «ninety days» removed from delivery UI.
+
+## Risks
+
+- Operator lowers retention while bookmarking old delivery URLs — existing
+  behaviour; copy already notes pruned rows are gone.
+- Settings change without restart — must be tested so log-tailer never keeps a
+  stale int from panel start only.
