release: 2.0.0: Panel redesign; new URLs; database from zero

The panel redesign (docs/plans/panel-redesign.md, 27/27). A breaking
release: every panel URL changed and the database starts from a single
baseline - a 1.x /data is not upgraded.

Since the last cut also fixed, all found on the test server:
  - the panel can read the mail queue;
  - port 25 answers with DMARC report ingest on, also next to the
    inbound relay;
  - DMARC reports reach the panel (the delivery service never worked
    since 1.7.0);
  - Postfix start-up warnings about the queue directory.

Cut: CHANGELOG [Unreleased] -> [2.0.0]; image pin 2.0.0 in compose,
README, guide; roadmap, plan and version table.

On the test server, on 252e5d1: go vet ./... ok, go test ./... ok
(22 packages), make e2e ok.

Full detail: CHANGELOG.md (2.0.0).

+**The contract** and **Enforcement** sections before touching a template.
+
+You are implementing a finished design. You are not designing.
+
+- Build pages only from Bulma classes in the `BULMA` list of `panel/check.py`
+  and from the `sp-` components on the components page, through their
+  partials. No other class, no hand-written component markup, no inline style.
+- No selector in `panel.css` that names a page or an id, uses `!important`, or
+  sets a width outside `WIDTH_OK`. If a page looks wrong, the layout choice is
+  wrong — do not patch it locally.
+- If a screen seems to need a component, state or layout that does not exist:
+  **stop and ask.** Do not approximate it, and do not substitute a look of
+  your own.
+- Never edit a mockup, `outlines.json`, `check.py`, the vendored Bulma or a
+  guard test to make your work pass. A failing guard means the implementation
+  is wrong. Design changes go mockup-first in a separate `design:` commit on
+  the owner's explicit instruction.
+- "Done" is evidence, not a description: passing `go test ./internal/web/...`
+  output plus a screenshot of each restyled page from the running container,
+  saved under `docs/assets/panel-redesign/evidence/` beside its mockup's name.
+  Report every difference from the mockup you could not remove; do not
+  describe a different result as the requested one.
+
+After editing a fragment in `panel/src/`: `python panel/build.py`, then
+`python panel/check.py` (add `--write` only when the structure change is the
+point of the commit).

+
+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.

+Full walkthrough — fetching the base files, setting up a reverse proxy and
+TLS (Apache/nginx/Caddy/Traefik), starting the container, and wiring up
+DNS — lives in the operator guide's [Full
+deployment](docs/guide.md#full-deployment) section, with proxy-specific
+commands under [Reverse proxy](docs/guide.md#reverse-proxy-mandatory).
 
-### 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.
-
-### 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).
+The compose file always publishes **465**, **587**, and **25**; Postfix listens
+on 587 only when `SUBMISSION_ENABLE=true`, and on 25 when
+`INBOUND_RELAY_ENABLE=true` and/or `DMARC_REPORTS_ENABLE=true` (see
+[Ports](docs/guide.md#ports)). Bump the

+## Supported versions
+
+SelfPost follows SemVer. Fixes are issued for the **latest minor release of the
+1.x line** only; there is no backporting to earlier minors. Upgrade before
+reporting if you are behind — the image tag is `ghcr.io/mixeme/selfpost:X.Y.Z`.

+| earlier 1.x | no — upgrade first |

+## Reporting a vulnerability
+
+**Do not open a public issue.** Use GitHub's private vulnerability reporting:
+the *Report a vulnerability* button under the repository's
+[Security tab](https://github.com/mixeme/selfpost/security). If you cannot use
+it, mail `public@mixeme.ru` instead.
+
+Useful in a report: the image tag, the reverse proxy in front of the panel, the
+steps to reproduce, and what an attacker gains. A relevant excerpt of
+`mail.log` or the panel's system log helps; strip recipient addresses first.
+
+**No response time is promised.** SelfPost is maintained by one person, and a
+deadline that cannot be honoured is worse than none. Reports are read and
+answered as soon as the maintainer is able; a fix ships in a patch release,
+with the timeline agreed in the thread.
+
+Disclosure is coordinated by request, not by demand: please hold public details
+until a patch is out. If you get no reply, that is not a request for a
+continued embargo — disclose at your own discretion. Reporters are credited in
+the CHANGELOG unless they ask not to be.
+
+## In scope
+
+The relay's job is to accept authenticated mail from an application and hand it
+to the internet as the operator's domain, and nothing else. Breaking that is in
+scope:
+
+- **Open relay** — mail accepted from an unauthenticated sender, or relayed for
+  a domain the sending application is not bound to
+- **SASL bypass** — sending without valid credentials, or credential recovery
+  from anything the container exposes
+- **Cross-domain access** — an application or a panel session reaching a domain
+  it was not granted
+- **Secret disclosure** — DKIM private keys, the admin password hash, session
+  tokens, or backup encryption material leaking to an unauthorised party
+- **Panel authentication and session flaws** — login bypass, session fixation,
+  CSRF on state-changing routes, privilege escalation
+- **Rate-limit bypass** — evading either the Postfix-level backstop or the
+  per-domain and per-application limits
+- **Container escape** or privilege escalation from the panel's unprivileged
+  user to root
+
+## Out of scope
+
+These are the operator's responsibility or accepted trade-offs, documented in
+[docs/security.md](docs/security.md) and the
+[operator guide](docs/guide.md):
+
+- Host configuration the operator controls: a blocked port 25, a missing or
+  wrong PTR record, DNS records not published, a self-signed or expired
+  certificate on the reverse proxy
+- Anything requiring the attacker to already have root on the host or write
+  access to the `./data` bind mount
+- Missing hardening headers or TLS options on the reverse proxy — SelfPost
+  never terminates HTTPS itself
+- Deliverability outcomes: mail rejected or filtered by a receiving provider is
+  a policy decision of that provider, not a defect
+- Denial of service through sheer volume against a single-tenant relay
+- Vulnerabilities in upstream Postfix, OpenDKIM, or the base image — report
+  those upstream; if SelfPost's configuration makes an upstream issue
+  exploitable when it otherwise would not be, that *is* in scope
+
+## Reports we cannot act on
+
+Automated scanner output with no demonstrated impact, and reports whose only
+content is a version number compared against a CVE list, are closed without
+investigation.

-| Route | Purpose |
+- **public** — `/healthz` (liveness), `/license` (the embedded `LICENSE`),
+  `/static/`, `/setup/`, `/login`, `/logout`;
+- **authenticated** — everything else, behind `RequireAuth`: a request without

+
+Both sit inside `secure()`, which sets the security headers and runs the origin

+holds the table: every path is registered with its methods, every menu entry

+contains an old path.
+
+### Who may open what
+
+Authorization is by tree where the tree is the boundary, and by object where it
+is not.
+
+- **`/server/` is guarded once.** Routes under it are registered through
+  `server()` in `web.go`, which wraps the handler in `globalOnly` (404 for
+  anyone but the global role — the answer a missing page gets, so the panel does
+  not confirm the page exists) and panics at start-up for a pattern outside
+  `/server/`. The handlers also call `requireGlobal()` themselves.
+- **Overview and the Outbound queue** are global-only but not under `/server/`,
+  so their handlers call `requireGlobal()`.
+- **Outbound is checked per domain.** `lookupDomain` resolves `{id}` and answers
+  404 for a missing domain and for one the principal may not reach alike
+  ([handlers/handlers_domains.go](../internal/web/handlers/handlers_domains.go));
+  application routes go on to check the application belongs to that domain.
+  Lists and the log are filtered by assignment in the query
+  (`ListDomainsForUser`), not in the template. Adding and deleting a domain is
+  `requireGlobal()`.
+- **Inbound is checked per inbound domain**, separately from outbound
+  ([handlers/handlers_inbound.go](../internal/web/handlers/handlers_inbound.go)):
+  `requireInbound` (the list), `requireInboundDomain` (one domain — page,
+  upstream, recipients, DNS re-check) and `requireInboundGlobal` (add, delete).
+  All three answer 404 alike.
+- **The DMARC hub** is open to anyone with outbound reach for the reports of
+  their own domains; the *Ingest* box (server-wide statistics) is rendered for
+  the global role only.
+- **Account and Help** are open to every signed-in user.
+- The principal ([web/auth/principal.go](../internal/web/auth/principal.go))
+  carries the role, the assigned outbound and inbound domain ids and the two
+  *All* flags; `CanAccessDomain` and `CanAccessInboundDomain` are the only
+  predicates. The reach, not the role, decides which menu groups exist.
+
+Routes marked global are tested per path for a user with the *domain* role,
+including another tenant's domain id
+([handlers/handlers_delegation_test.go](../internal/web/handlers/handlers_delegation_test.go),
+[authz_test.go](../internal/web/handlers/authz_test.go)).
+
+### Polled fragments
+
+A polled page answers its refresh at `<page>/fragment` (`/overview/fragment`,
+`/outbound/log/fragment`, `/server/health/fragment`, …). The fragment is the
+same `{{define}}` block that renders the page's own box, so the first paint and
+a refresh cannot differ. HTMX refreshes them every 5 s while the operator is
+active on the page, every 30 s when the tab is visible but idle, and not at all
+when it is hidden — scheduled in `panel.js` via `data-poll`, not
+`hx-trigger="every …"`, because a trigger filter is evaluated with `new
+Function`, which the CSP forbids. Polling does not extend the session idle
+timeout (only non-`HX-Request` `GET`s and mutating requests count as
+activity). The Outbound queue's retry-policy box is outside the polled region:
+it is the start-up `postconf -h` snapshot (see [Panel
+binary](#panel-binary-cmdpanel)), not a live re-read.
+
+### View engine and component kit
+
+Pages are rendered by [internal/web/view](../internal/web/view/view.go). There
+is one layout and one way to render.
+
+- **One layout.** Every page is parsed with `layout.html` (the shell: brick
+  navbar with the wordmark, the perforated edge, the strip of sibling pages,
+  user menu, footer) and `components.html` (the partials), then its own file.
+  `layout_signed_out` is the same document without navigation, used for sign-in
+  and setup; `Engine.Render` picks it when the page data names no user. The
+  page's file defines `content`; `pageFiles` in `view.go` lists the files of
+  each page, and fragments are listed in `fragmentFiles` and rendered by
+  `RenderFragment` with no layout.
+- **Typed page data.** A page's data is a struct that embeds `Meta` (title,
+  user, the viewer's reach, the menu group and page it sits in) and carries
+  the page's boxes and rows as fields, built by a constructor in the `view`
+  package (`NewOutDomain`, `NewHelp`, …) that the handler fills. The shell is
+  derived from `Meta` and the feature flags (`SetInboundEnabled`,
+  `SetDMARCEnabled`) in one place, `Engine.shell`, so which entries the menu
+  has is decided once. No template reads a `map[string]any`; the one map left
+  in the handlers is the health sampler's, which is turned into a typed
+  `Health` before rendering.
+- **The component kit.** [components.html](../internal/web/view/templates/components.html)
+  holds one `{{define}}` per partial (page head, postmark, box and its head and
+  foot, flash, health card, DNS record, facts, side menu, timeline, log pane,
+  empty state, confirm list, help topic, form rows) and is the only file that
+  writes their `sp-` markup. [components.go](../internal/web/view/components.go)
+  is the typed input of each (`Head`, `Box`, `Record`, `Fact`, `SideMenu`, …),
+  so a page passes a struct, never a `dict`. Template functions: `status_tag`
+  (a status → Bulma's tag classes, once), `wbr_at` (a break after the `@` in a
+  table cell). A page that needs a component the kit lacks is a design change
+  made in the mockups first
+  ([plans/panel-redesign.md](plans/panel-redesign.md) § The contract).
+- **Help.** [help.go](../internal/web/view/help.go) is the Help page's data:
+  topics grouped by section of the panel. A box's head links to its topic with
+  `Box.Help` (`/help#<topic>`), and the page lists only the
+  sections the viewer's menu shows.
+- **Assets.** [static/](../internal/web/view/static) is embedded
+  (`//go:embed`): vendored `bulma.min.css` and a Tabler icon subset (checksummed),
+  `panel.css` (the mockups' stylesheet, rule for rule), `htmx.min.js`, `panel.js`,
+  the IBM Plex subset and the logo files. Served with a content-derived `ETag`,
+  and `/static/` does not list its files. The kit page
+  `GET /server/components` renders every partial in every state from fixtures
+  (global role only).
+
+**Guard tests** hold the design in place; they run in `go test ./...` and CI.
+They read their rules from the accepted mockups
+([docs/assets/panel-redesign/panel/](assets/panel-redesign/index.html)) rather
+than keep a copy: `TestPanelClassVocabulary` (only the Bulma subset and the
+`sp-` classes of `panel.css`; every `sp-` class defined, used and shown on the
+components page), `TestPanelCSSIsTheMockupStylesheet`, `TestPanelCSSContract`
+(no `!important`, no id or page selector, type floor, widths),
+`TestTemplatesUseComponents` (no hand-written component markup in a page),
+`TestPanelOutlinesMatchMockups` and `TestPanelPageStructure` (each rendered page
+has the component skeleton of its mockup), `TestRedesignedPagesLoadOnlyTheKit`,
+`TestVendoredAssetsArePinned`, `TestStaticHoldsOnlyTheKnownAssets`,
+`TestRoutesFollowNavigation`, `TestNoTemplateUsesInlineScriptOrStyle`. The
+ratchet list `internal/web/view/legacy_pages.txt` is empty and can only shrink;
+the CI step
+[design-first](../.github/scripts/design-first.sh) rejects a commit that
+changes a guard together with the code it judges, and a template that is a
+byte-for-byte return of one from history. The design contract and the process
+are in [plans/panel-redesign.md](plans/panel-redesign.md) § Enforcement.
+
+### Security headers, CSP and scripts
+
+`secure()` ([internal/web/security.go](../internal/web/security.go)) puts these
+on every response: `Content-Security-Policy: default-src 'self'; object-src
+'none'; base-uri 'none'; form-action 'self'; frame-ancestors 'none'`,
+`X-Content-Type-Options: nosniff`, `X-Frame-Options: DENY`,
+`Referrer-Policy: no-referrer`, and `Strict-Transport-Security` when the cookie
+is `Secure`. Because the policy has no exemptions, no template carries an
+inline `<script>`, an event-handler attribute or `style="…"` — the page's
+behaviour is `htmx.min.js` plus `panel.js` (copy and *fill* buttons, the
+`data-confirm` prompt on destructive forms, conditional field visibility,
+adaptive polling), both optional: every form works as a native HTML `POST`
+with scripts off. htmx is told not to inject its indicator stylesheet
+(`htmx-config` meta), which the CSP would otherwise have to allow.
+
+State-changing requests (every non-`GET`/`HEAD`/`OPTIONS`) pass `originAllowed`
+first: `Sec-Fetch-Site` must say `same-origin`, or `Origin` must name the
+panel's host; a request with neither header is let through (an accepted risk).

+### Errors shown to users
+
+A validation refusal is shown as the text the validator wrote (on the form,
+next to the field, or in a notice above the first box). Anything else — a
+database error, `saslpasswd2`, a Postfix reload — is logged
+and the page gets a fixed sentence saying so; the error text never reaches the
+browser. A template error renders a bare `500` rather than a half-written page
+(`Engine.Render` buffers).
 
 ### Sessions
 
-Stored in SQLite (`sessions` table, migration `0002`): cookie holds a random
-token; the database stores **SHA-256 of the token**, not the token itself — a
-stolen DB or backup archive does not alone grant login, but a browser that still
-holds the cookie works after process restart, redeploy, or full backup restore.

+- **A session belongs to a user by id** (`sessions.user_id`, `ON DELETE
+  CASCADE`). Deleting a user ends their sessions; renaming one keeps them;
+  `RequireAuth` loads the user on every request, so a session whose user is
+  gone is a redirect to `/login`.
 - **Idle timeout** — sliding window, `PANEL_SESSION_IDLE_DAYS` (default 7); no
   absolute cap (regular use keeps the session alive indefinitely).
-- **Renewal** — DB `last_seen` and cookie `Max-Age` update at most once per hour
-  (`renewThreshold` in [internal/web/session.go](../internal/web/session.go)).
-- **Password change** — all other sessions are deleted; the current session stays
-  active ([internal/store/sessions.go](../internal/store/sessions.go),
-  [handlers_account.go](../internal/web/handlers_account.go)).

-after that backup was taken can become valid again if the browser still has the
-cookie and idle timeout has not expired.

+
+### Database
+
+The schema is one embedded baseline, `internal/store/migrations/0001_init.sql`,
+applied by `store.Open` into an empty file; `PRAGMA user_version` is `1` and
+`PRAGMA application_id` is `0x53503230` ("SP20"). There is no 1.x migration
+chain. **2.0 starts from an empty data directory:** a database with a schema
+version but without the 2.x `application_id` — what every 1.x file looks like —
+is refused at start with `ErrForeignSchema` and left untouched, as is one whose
+version is newer than the build knows. A restored 1.x backup fails the same
+way. Domains are carried across with a domain export, whose format is not the
+database. Later schema changes are new files (`0002_*.sql`, …); once `2.0.0` is
+released the baseline is never edited. History and the per-table list:
+[schema-migrations.md](schema-migrations.md).
+
+The tables that carry the panel's model:
+
+- **`users`** — `role` is `global` or `domain` (a reach, not a rank); `email` is
+  the user's own address, edited on Account and set by the global role on the
+  user form; `all_domains` / `all_inbound_domains` widen a *domain* user to
+  every domain of that direction, including ones added later (with a flag set
+  the assignment rows are ignored).
+- **`user_domains`** and **`user_inbound_domains`** — the outbound and inbound
+  domains assigned to a *domain* user. Separate tables: the same name on both
+  is two assignments, and a sending domain gives no inbound access or the other
+  way round.
+- **`sessions`** — `token_hash`, `user_id` (`ON DELETE CASCADE`), `expires_at`.
+  Keyed by user id, not by name.
+- **`domains`** — `dmarc_rua` is the whole of a domain's report-address choice:
+  `''` is no reports (a new domain), the address SelfPost derives for the
+  domain and the server's hostname is the hosted choice, anything else is an
+  address typed for the domain. Nothing refers to a user, and deleting one
+  changes no domain.
+- **`settings`** — key/value, what holds for the instance whoever is signed in
+  (send-log retention). Nothing that belongs to a user.
+- `applications` (with `auth_ip_restrict` / `auth_allowed_ips`),
+  `application_addresses`, `rate_limits` (no `allowed_ips` column), `send_log`,
+  `logtail_state`, `inbound_domains`, `inbound_transports`,
+  `inbound_recipients`, `dmarc_reports`, `dmarc_report_records`.
+
+The panel is the only writer; SQLite runs in WAL mode on one connection (see
+[Panel binary](#panel-binary-cmdpanel)), which is why a full backup snapshots
+with `VACUUM INTO` instead of copying the file.
 
 **Rotation:** send-log retention `SEND_LOG_RETENTION_DAYS` (default 90);
 `mail.log` via logrotate (14 rotated files, check every 6h, rename +
 `postfix reload` in `postrotate` — see § Log tailer above).
 
-**Backup:** panel button or `selfpost-backup` CLI — SQLite snapshot + tar of
-`/data` tree, minus `log/`, the setup token and any `tls/`; version check on
-restore. Stopped-container `tar` of `./data` is safe (see guide).
+**Restore:** panel button or `selfpost-backup` CLI — self-contained archive:
+`data/` (SQLite snapshot + tree minus `log/`, the setup token and any `tls/`
+under `/data`), `docker-compose.yml`, `.env`, and `certs/` when present;
+version check on restore. Requires the project directory mounted read-only at
+`SELFPOST_DEPLOY_ROOT` (`/selfpost-deploy` in the default compose file). On the
+first successful boot after restore, the panel runs one **Resync** — OpenDKIM's
+tables, Postfix's sender map, inbound relay maps (when
+`INBOUND_RELAY_ENABLE=true`), and DMARC maps (when `DMARC_REPORTS_ENABLE=true`)
+are re-derived from SQLite and both daemons are reloaded, so drift between the
+extracted archive and the database is healed before mail flows. Manual
+`POST /server/health/reload` (the *Reload configuration* button on Server ›
+Health) resyncs OpenDKIM, the sender map, and
+inbound maps only — not DMARC maps. Stopped-container
+`tar` of `./data` alone remains possible for state-only copies (see guide).
 
 **Optional encryption** of the two secret-bearing downloads
 ([internal/secretfile](../internal/secretfile/secretfile.go)): password →
 scrypt → AES-256-GCM over 64 KiB chunks, each authenticated with the header,
 its counter and an end-of-stream flag (so truncation and reordering fail to
 open). Full backup `.tar.gz` → `.spbk` (SelfPost backup), domain export
-`.json` → `.spde` (SelfPost domain export); the plain forms remain the
-default. Domain import detects the envelope by magic bytes; an encrypted full
-backup is converted back with `selfpost-backup -decrypt` before restore.

+  or two clicks away. It takes the postal signature of <strong>A</strong> — the postmark verdict, numbered mono section
+  heads, the stamp's perforated paper edge under a brick bar that carries the wordmark — and the icons of <strong>B</strong>. Thirty-four screens and a components page live in
+  <a href="panel/overview.html">panel/</a>. Serve this folder from the repository root: the pages load the panel's own

+  <h2>What changed against today's panel</h2>
+  <ul>
+    <li><strong>Overview shows verdicts, Health shows tables.</strong> Process lists, socket paths and interface counters moved to
+      <em>Server › Health</em>, one click from each card.</li>
+    <li><strong>Every page is one of three layouts</strong>: a list (form on top, table below), a detail page (sticky side menu +
+      numbered boxes), or a form page (boxes in equal columns). No page picks its own width.</li>
+    <li><strong>Own password is Account</strong>, instance defaults are Settings. Export sits with the domain, import with Backup,
+      and each links to the other.</li>
+    <li><strong>Queues are tables</strong>, not a <code>postqueue -p</code> dump — this needs <code>postqueue -j</code> parsing.
+      The inbound queue is the same queue filtered by recipient domain.</li>
+    <li><strong>Confirm pages say what will be lost</strong> as a list, beside a hint for the usual alternative (export before delete).</li>
+    <li>Own components on top of Bulma: postmark, perforated edge, numbered box head, health card, DNS record block, facts grid,
+      timeline, log pane. The mockup's <code>theme.css</code> is about 200 lines.</li>
+    <li><code>panel/build.py</code> wraps the fragments in <code>panel/src/</code> with the shared navbar; the built pages are committed,
+      so nothing has to be run to view them.</li>
+  </ul>
+
+  <h2>Stage 1 · three directions on three key screens</h2>
+  <p class="lead">Kept for the record: Overview, an outbound domain and sign-in, drawn three ways.</p>
+
+  <h2>Shared by all three</h2>
+  <ul>
+    <li><strong>Navigation by mail direction.</strong> Overview · <em>Outbound</em> (Domains, Log, Queue, DMARC reports) ·
+      <em>Inbound</em> (Domains, Log, Queue) · <em>Server</em> (System log, Backup, Users, Settings). Account, Help and
+      Sign out live with the user name. Eleven flat entries become four groups.</li>
+    <li><strong>One block per DNS record.</strong> Today "DNS status" and "records to publish" show every host twice.
+      Here a record is one block: its status, what to publish, and — only on a mismatch — what DNS holds now.</li>
+    <li><strong>The domain page stops being nine cards.</strong> DNS and applications are the page; limits, report address,
+      export and delete are "rarely changed" and sit behind one click.</li>
+    <li><strong>Applications are a table</strong>; editing one is its own form page instead of a three-column panel inside a list row.</li>
+    <li>Brand carriers stay: the stamp, brick, IBM Plex. No inline <code>style</code> or script in any mockup.</li>
+  </ul>
+
+  <h2>The directions</h2>
+  <div class="cards">
+    <section>
+      <p class="kicker">A · Pico CSS 2.1</p>
+      <h3>Blank</h3>
+      <p>The panel as a postal form: one centred sheet, numbered sections, mono field labels, a postmark for the
+      verdict. Overview is a ledger — one row per check, the row opens into its detail. Sections on the first
+      header row, the section's pages on the second.</p>
+      <p class="links"><a href="a/status.html">Overview</a><a href="a/domain.html">Domain</a><a href="a/login.html">Sign in</a></p>
+    </section>
+    <section>
+      <p class="kicker">B · Tabler 1.5 (Bootstrap 5)</p>
+      <h3>Console</h3>
+      <p>The classic admin kit: ink sidebar with every page one click away, status tiles, cards and tables in a
+      12-column grid, read-only input groups with Copy. Almost nothing is ours; it also looks the most like
+      every other admin panel.</p>
+      <p class="links"><a href="b/status.html">Overview</a><a href="b/domain.html">Domain</a><a href="b/login.html">Sign in</a></p>
+    </section>
+    <section>
+      <p class="kicker">C · Bulma 1.0</p>
+      <h3>Counter</h3>
+      <p>Brick top bar with CSS-only hover menus. Overview is the whole service on one screen: a health strip over
+      the outbound and inbound domain lists. The domain page gets a sticky side menu. Softer, rounder, the
+      boldest use of the brand colour.</p>
+      <p class="links"><a href="c/status.html">Overview</a><a href="c/domain.html">Domain</a><a href="c/login.html">Sign in</a></p>
+    </section>

+
+  <h2>Open points</h2>
+  <ul>
+    <li>Icons in B come from Tabler Icons (MIT) through its webfont for the mockup; the panel would vendor only the used glyphs as an SVG sprite.</li>
+    <li><em>Inbound log</em> rides on the agreed <code>inbound-antispam-panel</code> journal; <em>Inbound queue</em> is a new filter over the one Postfix queue and needs its own roadmap row.</li>
+    <li>Dark scheme and the narrow-screen shell are not drawn at this stage; all three libraries ship both.</li>
+    <li>The earlier <a href="../panel-ui/index.html">panel-ui</a> experiment and <a href="../../plans/panel-redesign.md">panel-redesign.md</a> are superseded by whichever direction is accepted.</li>

Publish all three exactly as shown; merge SPF into an existing record rather than adding a second one. A domain's status is the worst of its three records, and results are cached for a few minutes, so use Re-check DNS after publishing. The SPF check is shallow: it looks for this server's address in the record itself and does not follow <code>include:</code> or <code>redirect=</code>, so a record that relies on them is reported as a warning, not a failure. <code>p=none</code> does not affect delivery; tighten to <code>quarantine</code>, then <code>reject</code>, once the reports look clean. A domain's report address is set in its Domain settings.</p></div>

It may send as any address of its domain or only as listed addresses, and, with a list of client IPs set, only from those addresses. The password is shown once at creation or regeneration and is not stored in readable form.</p></div>
+          <div class="sp-help-topic" id="limits"><h3>Rate limits</h3><p>Level 1 is a per-IP ceiling set in <code>.env</code>. Level 2 is optional, per domain and per application, entered by hand or computed from the last 30 days of sending, and can never exceed level 1. An application's own limit replaces its domain's.</p></div>
+          <div class="sp-help-topic" id="log"><h3>Outbound log</h3><p>One row per message and recipient, with the status Postfix last reported: queued (accepted, nothing reported yet), sent (the receiving server took it; what the mailbox does next is not reported back), deferred (not taken yet, Postfix tries again), bounced (failed for good, or the queue lifetime ran out) and rejected (refused before queueing under a level-2 rate limit, so it never reached Postfix). A message's page lists these steps and the lines Postfix wrote about it in <code>mail.log</code>, found by queue id; that file is rotated daily and about two weeks are kept, so an old message may show none. Rows are deleted after the retention set in Server › Settings, 90 days by default. A domain administrator sees only the rows of their own domains.</p></div>
+          <div class="sp-help-topic" id="queue"><h3>Queue and retries</h3><p>The page lists, as <code>postqueue -p</code> prints it, the messages Postfix has accepted and not yet delivered: mail being sent right now and mail deferred for a later attempt. Only the global role can open it, and it only shows; nothing here deletes or forces a message. A deferred message is tried again after the first retry delay, then at gaps that double up to a cap, until the receiving server takes it or the queue lifetime runs out and it bounces; there is no attempt counter, and the box on the page shows this server's values. A queue that keeps growing means a receiver is refusing or not answering: open the message from the Outbound log to read the reason Postfix logged.</p></div>
+          <div class="sp-help-topic" id="dmarc"><h3>DMARC reports</h3><p>An aggregate report is the summary a receiving provider sends, usually daily, to the <code>rua=</code> address of your DMARC record: which servers sent mail as your domain and whether SPF or DKIM passed for it. A domain's report address is one of three choices, set in its Domain settings: no reports (the default for a new domain), the SelfPost hosted address (an address on this server whose reports are parsed and shown under DMARC reports; offered only while hosted reports are enabled on the server), or an address typed for the domain (an ordinary mailbox that receives the raw XML; a button fills in your own profile e-mail). When the typed address is on another domain than the one sending, that domain must publish a report-authorization record, or providers will not send; the domain's page shows it with the other DNS records and checks it. In the tables pass means SPF or DKIM passed and aligned, fail means neither did, and your own server shows as <em>this relay</em>. A fail from any other source is someone else sending as your domain — a forwarder, an application you forgot, or abuse — so do not tighten <code>p=</code> until that sender is fixed or removed. A domain administrator reads the reports of their own domains.</p></div>
+        </div>
+        <div class="box">
+          <div class="sp-box-head"><span class="sp-no">03</span><h2>Inbound</h2></div>
+          <div class="sp-help-topic" id="inbound"><h3>Backup-MX and forwarding</h3><p>An optional backup-MX or forwarder, switched on in the server's <code>.env</code>; the Inbound menu exists only then. Postfix accepts mail on port 25 for the listed domains only and hands each message on to that domain's upstream; there are no mailboxes. For each domain publish the MX record its page shows, and keep a primary MX the domain already has if this is a backup. The MX tag is green when at least one MX of the domain points at this server, and a domain accepts no mail until an upstream is saved on its page. Adding and deleting domains is for the global role.</p></div>
+          <div class="sp-help-topic" id="upstream"><h3>Upstream</h3><p>The upstream is the server that actually holds the mailboxes. Give its host and port — used exactly as written, with no MX lookup — and choose the TLS for the hop to it: Opportunistic uses TLS when the upstream offers it and otherwise sends in the clear, Required holds the mail until a TLS session is possible, Off never uses TLS. While the upstream does not answer, Postfix keeps the mail and retries as for any other mail.</p></div>
+          <div class="sp-help-topic" id="recipients"><h3>Valid recipients</h3><p>Choose whom this domain accepts. Listed addresses only: the relay accepts exactly the addresses you list, one per line or comma-separated, and refuses any other while the sender is still connected, so it never has to send a bounce for them. Any recipient: everything at the domain is accepted and passed on, and an address the upstream then rejects comes back as a bounce from this server to a sender who is often forged — backscatter. Prefer a list, and keep it in step with the mailboxes upstream.</p></div>
+          <div class="sp-help-topic" id="filter"><h3>Spam filter</h3><p>The spam filter belongs to the server, not to a domain. The server's administrator attaches it in the server's <code>.env</code>, and from then on every inbound domain is screened by it before mail is handed on; the box shows on or off and has nothing to switch. Off means mail goes to the upstream unfiltered. While the filter is down, mail is either accepted unfiltered (the default) or deferred, so the sending server tries again later, as the server's setting says; the box states which.</p></div>
+        </div>
+        <div class="box">
+          <div class="sp-box-head"><span class="sp-no">04</span><h2>Server</h2></div>
+          <div class="sp-help-topic" id="backup"><h3>Backup and moving a domain</h3><p>Full backup downloads one archive of the whole instance: <code>data/</code> (the database, DKIM keys, application credentials and the queue), <code>docker-compose.yml</code>, <code>.env</code> and <code>certs/</code>. It holds secrets, so leave Encrypt with a password ticked: the file is sealed as <code>.spbk</code>, the password is not stored, and without it nothing can be recovered. To restore, unpack it into an empty project directory (decrypt a <code>.spbk</code> first with <code>selfpost-backup -decrypt</code>) and start the same SelfPost version that made it; the panel refuses data from another version. The reverse-proxy configuration and <code>mail.log</code> are not included. One domain moves on its own: Export domain on its settings page writes a <code>.json</code> (or encrypted <code>.spde</code>) with its DKIM key and its applications' passwords, and Import a domain here reads it into another instance, so the published DNS needs no change.</p></div>
+          <div class="sp-help-topic" id="users"><h3>Users and roles</h3><p>The two roles are a reach, not a rank: every user is an administrator and signs in with a username and password. Global reaches the whole server — Overview, Server, the queue and every domain — and is the only role that adds or deletes domains and users. Domain reaches only the domains assigned to it, outbound and inbound separately (the same name on both lists is two assignments); <em>All</em> includes domains added later, and a domain user needs at least one domain or <em>All</em> on either list. The only global user cannot be demoted or deleted, and you cannot delete the account you are signed in with. A new password set here signs that user out of their other sessions.</p></div>
+          <div class="sp-help-topic" id="settings"><h3>Settings</h3><p>Settings holds what is true of the whole instance. Log retention is how many days the Outbound log keeps its rows, from 7 to 365 and 90 by default; a sweep every six hours deletes older ones, and it is the main driver of how fast <code>/data</code> grows. It does not change the rotation of <code>mail.log</code>, which is daily with about two weeks kept. The sending rate limit shown under it is level 1, the per-client-IP ceiling set in <code>.env</code>: changing it needs a restart, and no level-2 limit can exceed it.</p></div>
+        </div>
+        <div class="box">
+          <div class="sp-box-head"><span class="sp-no">05</span><h2>Account</h2></div>
+          <div class="sp-help-topic" id="account"><h3>Your account</h3><p>Account is your own, whatever your role: your username and e-mail, and your password. Changing the password signs out every other session of this account and keeps the one you are using; applications have their own logins and are not affected.</p></div>
