Codeberg is being retired as the project's public site, so every reference now
points at GitHub. That includes the Go module path (codeberg.org/mix/selfpost →
github.com/mixeme/selfpost): leaving an import path on a host that is going
away would break `go get` and `go install`, so this is not only a docs change.
Touches go.mod, test/e2e/go.mod, all imports, Makefile MODULE, the -ldflags
version stamp in build/Dockerfile and docs/development.md, the licence headers
in the SVG/HTML assets, and README (no more primary/mirror pair).
Comments no longer cite the archived specification. "spec 7.6.1", "spec 5.1"
and friends pointed into docs/archive/specification-v1.0.md, which is marked as
not a source of truth; each is now a reference to the live document that owns
the subject — architecture.md (with section), product.md, security.md or the
README. The review only asked for the 7.x refs (code-review.md § 4), but 4/5/6/
8/9 had the same defect, so they went too. Comments only, no behaviour change.
Also closes the remaining review items: architecture.md gained a Code layers
section with the layer diagram (A2), and TestParseDelivery gained the exotic
mail.log cases (§ 3).
Fixes a bug that last test found: the delivery-line pattern matched status=
greedily, taking the *last* occurrence on the line. Postfix appends the remote
server's reply verbatim, so a rejection whose reply quoted "status=sent" was
filed as a delivered message in the send log. It now takes the first status=
after the recipient, which is the real field.
R7 (CONTRIBUTING.md) moved to roadmap 2.x — one developer, no external PR flow,
so the file would have no audience yet. R1 (compose image tag) and the git tag
stay in roadmap § v1.x as the release-commit steps.
gofmt/go vet clean on both modules; go test ./... green except the three known
Windows-only failures (file perms, backslash paths, renaming an open file).
Not exercised on the dev server — no Docker locally.

- logtail: persist the read position (offset + fingerprint of the log's
first 512 bytes) in a new logtail_state table (migration 0003) and
resume from it on start, so delivery lines written while the panel was
down are parsed instead of skipped and their send-log rows no longer
stay "queued" forever. Fingerprint mismatch (rotated/recreated while
down) reads the file from the start — re-parsing is idempotent; a
first-ever start with nothing stored still begins at end-of-file.
Writes are throttled to one per 5s, forced on rotation and shutdown.
- milter: count messages that passed the level-2 check but have not
reached the send log yet (internal/milter/inflight.go), so concurrent
SMTP sessions cannot each spend the same last slot. A literal
count+insert transaction, as the review suggested, is not possible:
the count happens at MAIL FROM and the insert at end-of-message.
Reservations are released after the insert, on ABORT, and after a
10-minute TTL — a client that drops mid-transaction must not be able
to hold a slot, since the limiter is fail-open by design.
Docs: architecture.md (log tailer, persistence, L2 counting),
security.md and roadmap.md (restart gap closed, container recreate
remains), CHANGELOG, progress.md, code-review.md.

Both secret-bearing downloads can now be sealed with a password. Unticked, the
forms produce exactly the files they did before.
- internal/secretfile: envelope format — magic/type/scrypt params/salt/nonce
prefix header, then 64 KiB AES-256-GCM chunks each authenticated with the
header, its counter and an end-of-stream flag, so truncation, reordering and
tampering fail to open instead of restoring a plausible prefix. Streams both
ways, so a full backup never sits in memory.
- Panel: "Encrypt with a password" checkbox on the full-backup and
domain-export forms (shared partial, toggled from panel.js — no inline
script); domain import detects an encrypted export by magic bytes, not by
extension, and asks for the password.
- selfpost-backup: writes .spbk when given a password and converts one back
with -decrypt, which a restore needs. The password comes from
SELFPOST_BACKUP_PASSWORD or -password-file, never argv.
- Docs: README, security.md (+ accepted risk: encryption stays opt-in),
architecture.md, progress.md, CHANGELOG.
Verified locally: panel-encrypted archive decrypts through the CLI and unpacks;
wrong password and password mismatch are refused; UI checked in a browser.

Removes ~30 stale "Phase N" / historical-staging comment references from
code and shell scripts now that v1.0 is done; fixes a stale dashboard
comment claiming applications/send-log were unimplemented; adds a CSRF ADR
to security.md documenting the Origin-check-over-tokens decision; resolves
docs/logo in roadmap.md (directory doesn't exist, criterion already met);
adds a gofmt -l check to CI so unformatted Go fails the build.
The known-limitations write-up for the log-tailer offset gap (the other
Phase 1 item) was already present in architecture.md § Log tailer, so no
change was needed there.

The document is closed: no unique content remains — § D (pre-release
security review) is duplicated in progress.md, security.md and the
CHANGELOG, and B.1-B.3/C.4 were trimmed in 22f86d1. It stays until the
tag only because it describes the release gate.
Record the retirement as a v1.x tail item in roadmap.md with the
concrete steps: archive the file and retarget its references, including
the stale "plan C.4" pointers in Makefile, release.yml and the e2e test.

Fable review of the full diff from the v1.0 audit (Phase 11, bd64e80) to
HEAD plus a complete pass over the docs/security.md checklist (former spec
7.6). No exploitable findings. One defence-in-depth fix: the application
login is passed to saslpasswd2 behind a -- end-of-options marker so a
login starting with - can never be parsed as a flag. Accepted risks

The four brand files were authored with live <text> set in IBM Plex Sans, and
the proof sheet closed on that being the one thing still to do before they were
used anywhere. It matters more than it sounds: the mark *is* the weight contrast
between Self at 200 and Post at 600, and a machine without Plex resolves neither
weight — browsers synthesise bold but never light, so the two words come out the
same and the wordmark stops being one. Almost no viewer has the font installed.
Laid out from the font's own metrics the way a browser would (advance widths
from hmtx, CSS letter-spacing after every character including the last, the
anchor centred on the result) and emitted as one path per text element, so the
files now render as drawn with no font installed at all. The note at the foot of
the proof sheet records that, and its file list is corrected to docs/assets/,
where these have lived since they were added.

The documentation is part of the deliverable (spec 11.5/11.7/11.9), so it has
to describe what the code does, not what was intended. Adds
docs/documentation-plan.md: the package inventory against the spec, the
per-claim sources of truth in the tree, the results of a first cross-check
pass (11 findings, most notably the missing "operations" section required by
spec 11.7, the absent env-var reference, .env.example's dangling link to a
README "Rate limiting" section, and the unwritten "tar while stopped" backup
path from spec 9), and tasks D1-D7 gating the next release tag.
progress.md points at it so it survives a context reset.

Separate test/e2e Go module drives the shipped deploy/docker-compose.yml
(plus a test-only override: self-signed cert, low ports, isolated compose
project) against a fake DNS zone (CoreDNS) and an smtp-sink MX, exactly as
an administrator and their applications would over HTTP/SMTP — covering the
class of failure unit tests can't see (container wiring). Positive path:
setup -> login -> domain -> DKIM record published into the fake zone ->
application -> SMTP AUTH send -> DKIM verified against the DNS-published
key -> send-log queued->sent. Negative: no-AUTH/unauthenticated relay,
sender/login mismatch, L1 (anvil) and L2 (panel) rate limits, journal-milter
fail-open, SELFPOST_HOSTNAME gate, session survives docker restart.
release.yml moves off qemu to a native per-arch build (amd64/arm64), each
gated by this suite before its tag is pushed and merged into the version
manifest.
Verified green on selfpost.mixfed.ru via `make e2e`; go vet/gofmt clean in
both modules.

Unset or malformed hostname makes the panel and Postfix diverge on SASL
realm silently (auth breaks for every application) and breaks HELO/PTR
matching (spam), so entrypoint.sh now exits before postfix-config.sh /
supervisord with an explanatory error, plus a syntax check rejecting
missing dots, schemes, ports, and whitespace.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Replaces copytruncate with rename + `postfix reload` (the same mechanism
`postfix logrotate` itself uses), closing the up-to-one-second window where
copytruncate could drop in-flight delivery lines and leave a send-log row
stuck at "queued" forever.
logrotate-mail.conf keeps `create 0644 root root` rather than `nocreate` as
originally planned: verified on a live container that Postfix recreates the
file itself only lazily, on the next write after reload, and at mode 0600 —
unreadable by the unprivileged panel process. `create` hands the file back at
0644 immediately after rename, before Postfix ever touches it.
logtail.follow() re-drains the old file descriptor once more right before
switching to the rotated file, closing the residual gap between the last
poll's drain and the rotation check. readLogTail() treats a momentarily
missing mail.log as an empty screen rather than a logged error.

Sessions move from an in-memory map (absolute 12h TTL) to a `sessions`
table (migration 0002), storing only the SHA-256 of the token. Expiry is
now a sliding idle window (PANEL_SESSION_IDLE_DAYS, default 7, no
absolute cap), extended at most once an hour and never by the
monitoring screens' background polling (GET + HX-Request), so a
forgotten open tab doesn't keep a session alive indefinitely. A login
now survives a container restart or redeploy.

The plan holds undone work; an accepted risk is a decision, not a task
— it has no place in a queue, only a condition for revisiting it. Both
risks (POST with neither Sec-Fetch-Site nor Origin, no session-bound
CSRF tokens) move verbatim into a new docs/security.md, which also
states where D.5 findings land. Section letters and item numbering in
the plan stay as they were, since progress.md and the commit history
reference them; a note in their place points at the new file.

A single security pass once B.1-B.3 and C.4 are in, not four per-item
passes: those four rewrite authentication, log-file handling, the
entrypoint gate and the release workflow, so what matters is the final
state. Scope is the whole diff since v1.0.0 (phases 12-14 included)
plus a fresh walk over spec 7.6, run by Fable rather than Opus so the
reviewer is not the author. Findings are either fixed before the tag
or recorded in section A as accepted risks; together with the C.4 e2e
this gates tagging. The old section D (2.x pointer) becomes E, its
items renumbered 6 and 7.

2FA is dropped from the 2.x candidate list. "Multiple administrators"
is narrowed to one concrete role: an admin scoped to a single domain
(its applications, DKIM/DNS status, filtered send log), with the
globally scoped actions — domain add/delete, reload, full backup,
queue and mail.log tail — left out of it. Still 2.x: a second panel
subject contradicts the out-of-scope list in spec section 3, so it
needs agreement and a spec change before any code.

The unit tests all fake the process boundary, so the class of failure that
actually broke this project — container wiring: chroot vs DNS, milter socket
permissions, the SASL realm, the Postfix reload path, cap_add — is invisible
to them. Record the decision to close it with a hermetic containerised e2e:
a separate Go module under test/e2e/, driven against the shipped compose file
plus an override, with a fake DNS zone and an smtp-sink standing in for the
outside world.
It runs before tagging (make e2e on the dev server, plus workflow_dispatch)
and gates image publication on the tag itself, which pulls release.yml off
qemu onto a native amd64/arm64 matrix: build, test, push per-arch tags, merge
the manifest — so the bytes published are the bytes that were tested.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The soft fallback is worse than the plan's wording implied: the panel
falls back to realm "localhost" while postfix-config.sh falls back to the
container hostname, so with the variable unset accounts are written under
one realm and looked up under another — SMTP auth fails for every
application while the panel looks healthy. The second failure (EHLO =
container id, no PTR/SPF match) is invisible entirely. Both are silent
and delayed, which is exactly what a log warning cannot fix.
Decision: entrypoint.sh refuses to start without the variable, with an
explanatory message rather than a one-liner, plus a syntax check on the
value. Records why the "panel up with a banner, mail dead" variant was
rejected: it contradicts the Phase-4 crashexit invariant, cannot be fixed
without a restart anyway, and would let the panel persist SASL accounts
under the wrong realm.

copytruncate loses log records twice per rotation: everything written
since the tailer's last poll (kept in mail.log.1, but skipped because the
descriptor points at the truncated inode) and whatever lands between the
copy and the truncate (gone for good). Those records carry the final
delivery statuses the send log is reconciled from, so a dropped line
means a row stuck in "queued" — not just a gap in the monitoring view,
as the item previously assumed.
Decision recorded, implementation deferred to its own step.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Sessions move from the in-memory map to a `sessions` table (migration
0002), so a restart, a redeploy or a restore from a full backup no longer
signs the administrator out. The row holds a SHA-256 of the token rather
than the token itself: a stolen database file or backup archive cannot be
replayed into a login, while the browser that still holds the cookie keeps
working across a restore.
The 12-hour absolute TTL becomes a sliding 7-day idle window, configurable
through PANEL_SESSION_IDLE_DAYS (whole days, mirroring
SEND_LOG_RETENTION_DAYS). No absolute cap: for an administrator who visits
regularly the session lasts indefinitely, which is the accepted trade-off.
The four `every 5s` monitoring fragments deliberately do not renew it —
otherwise a forgotten open tab would hold the session open forever and the
window would mean "seven days without an open tab" rather than "seven days
without the administrator".
Decision only; no code yet.

The plan holds only open work, but section A still retold what phase 14
implemented — security headers, the origin check, the __Host- cookie, the
setup-token documentation — which the CHANGELOG and git history already
describe in full. What is left of A is the two things deliberately *not*
closed: the POST that carries neither Sec-Fetch-Site nor Origin, and the
absence of session-bound CSRF tokens. The XSS note folds into the token item,
which is the only place it was doing work; the "proxy must pass Host through"
requirement is documented in the README and in the CHANGELOG, so it goes.
Section A's numbered items are gone with it, so B-D renumber from 1. Nothing
else in the file has been implemented: the README still says nothing about
restarts signing the admin out or about the copytruncate rotation window,
SELFPOST_HOSTNAME still falls back to localhost without a warning, and CI
still runs only vet and unit tests.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
14.C needed no code: the setup link is already mirrored to /data/setup-token
at 0600 and removed once setup completes. What was missing is the reason to
prefer it — a deployment whose container logs ship to a central aggregator
otherwise leaves a live bearer token in that pipeline for ten minutes, and in
whatever retains it afterwards.
The reverse-proxy section gains the one requirement 14.A introduces: pass the
original Host header through. Everything else about security stays the
proxy's non-problem, which is the point of emitting the headers from the
panel.
Phase 14 leaves the plan (the file describes only unfinished work), but its
section A keeps what was deliberately left open: the accepted risk for clients
sending neither Sec-Fetch-Site nor Origin, the decision not to add
session-bound CSRF tokens and what would justify revisiting it, and the fact
that XSS inside the panel's own origin is answered by html/template and the
CSP rather than by either of those.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Records both decisions and, more usefully, what the item was actually about.
The prefix was filed as a free nicety ("мелочь, но бесплатная"), which is why
it sat undecided: nothing said what it prevents. It prevents the same-site
neighbour from the CSRF item using its other lever — setting a Domain-scoped
cookie of the same name. The browser then sends two, r.Cookie returns the
older one, and the admin logs in successfully into an endless login loop. That
is denial of service rather than compromise (no valid token can be forged with
a single account), but it is close to undiagnosable from the panel's side, and
the origin check decided in A.2 does nothing about it — the request comes from
the admin's own origin.
Phase 14 gains section B: the cookie name becomes conditional on CookieSecure,
because a __Host- cookie over plain HTTP is rejected outright and would break
the dev mode silently; logout clears both names; and requireAuth switches to
r.Cookies() so a duplicate is refused and logged instead of silently picked.
The setup-token documentation moves to 14.C.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Records variant (b): the panel will check Origin / Sec-Fetch-Site in the same
middleware as the security headers, and will not carry CSRF tokens. The
coverage table above the decision already says what that buys; what the item
was missing is what it does not buy, so both are now written down — the
accepted risk (a client sending neither header still gets through, which is
exactly the old-browser row) and the two escalation paths with their price,
tightening the policy to reject those requests, or session-bound tokens.
Phase 14.A grows the implementation rules: which requests are checked, the
three-way decision, and the fact that only the host is compared because the
panel sits behind a proxy and never sees its own external scheme. The rule
depends on r.Host being the external name — all four shipped proxy fragments
preserve it (checked), but a proxy that rewrites Host would turn every POST
into a 403, so the rejection has to log both sides of the comparison and the
container test has to run through a real proxy.

The options were buried in three prose bullets that mixed mechanism, cost and
coverage, so the one question that matters — which attacker each variant stops
— could not be read off the page. They are now a table: four scenarios by
three variants, with the cost and the caveats underneath and the scenario
prose moved below the table for whoever wants the detail.
No change of substance: same variants, same recommendation (the Origin /
Sec-Fetch-Site check in the phase 14.A middleware), same caveat that a naive
double-submit token leaves the subdomain row open.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The item said SameSite=Lax was "enough for modern browsers" but wrong "on a
downgrade to an old browser or unusual proxies", which named the least likely
scenario and missed the most likely one: SameSite is scoped to the registrable
domain, not the origin. The panel runs on a subdomain, so any page anywhere
under the operator's domain — the CMS on www, a stale CNAME, a neighbouring
service — is same-site and its POST carries the session cookie.
It also said nothing about what a successful CSRF would actually buy. Almost
everything is a blind write the attacker cannot read, except POST
/domains/import: multipart is a CORS-simple content type, and a domain export
carries a DKIM key and working SASL passwords, so an attacker uploads
credentials they already know and gains a sending identity on someone else's
relay. That single endpoint, not the destructive ones, is what sets the bar.
The options now carry their cost and their limits: an Origin/Sec-Fetch-Site
check in the phase 14.A middleware closes the subdomain case for ~15 lines,
while a naive double-submit token does not close it at all, since a same-site
neighbour can write the parent domain's cookie. Route facts, cookie
attributes, the export struct and the absence of any hx-post were checked
against the code rather than assumed.

The plan is meant to hold only what is still open, but three of its numbered
items had already been implemented and were still being read as pending work:
the TRUSTED_PROXY_CIDR-gated X-Forwarded-For handling (A.1), the account
settings page (A.6) and the go vet/go test CI workflow (C.10). Remove them
and renumber; the residual scope note from A.6 (2FA, multiple admins) moves
to section D, which is where deliberately deferred scope belongs.
Same for the "done" notices at the top of the plan and the phase-by-phase
retellings in progress.md: phases 12 and 13 are described in full in the
CHANGELOG and git history, so the tracker now states what is closed and what
is next, and nothing else.
Three code comments cited plan item numbers that this renumbering would have
silently pointed at a different item, and one cited a phase 13 section that
no longer exists; they now state the fact instead of the reference. The CI
test workflow was never recorded in the CHANGELOG, so its entry is added
there before the plan item describing it goes away.

Phase 13. Two new packages and one new screen.
internal/health owns the shared status vocabulary (ok/warn/error/unknown)
and the local checks: supervisord's process table, TLS certificate expiry
and the two milter sockets. Each check reports a problem as a status rather
than an error, so one broken component costs a line and not the page.
internal/dnscheck does the read-only lookups: forward-confirmed reverse DNS
for SELFPOST_HOSTNAME, and per-domain DKIM (compared against the key this
server actually signs with), SPF and DMARC. Every check is bounded by a
timeout and cached, and the resolver sits behind an interface so the tests
drive every branch without touching the network. The SPF check is
deliberately shallow: it looks for a mechanism literally covering the
server's address and does not follow include:/redirect=, so a record that
authorises us through an include is reported as "cannot tell" rather than
as a failure.
/status renders both, with the local checks in an HTMX-polled fragment and
the DNS lookups behind a Re-check button, and becomes the panel's landing
page: / now redirects there and the domain list lives at /domains. The
Reload button moves onto /status, where it reads as what it is — a
drift-recovery for the daemons — with text explaining what it regenerates.
A template test fails on any remaining href="/" so a stale link cannot
silently land on the wrong screen.
Also fixes a defect this made visible: the panel could never read the mail
queue in the documented deployment. postqueue relies on its setgid-postdrop
bit, which the compose file's no-new-privileges disables, so the Queue
screen always said "Could not read the mail queue" — including in the
released 1.0.0 image. The panel user is now a real member of postdrop,
which needs no setgid transition.
Verified in a container on the dev server against real DNS: PTR matching
(selfpost.mixfed.ru) and not matching (mixfed.ru), DKIM absent and
mismatched, SPF absent and via include:, DMARC p=quarantine/p=reject/absent,
and a resolver timeout degrading to "unknown" without hanging the page.

Phase 12 (UI/UX). The navigation bar now renders once from layout.html
instead of being copied into each content template, so it is present on
every authenticated page — including the domain page and its delete
confirmation, which had no links at all — and the current page is
highlighted via .Active rather than quietly dropping out of the list.
New /account page changes the administrator's username and/or password:
the current password is required and the attempt is throttled on the same
limiter as the login form, so this route cannot be used to brute-force
past that limit. A password change invalidates every other session while
keeping the one performing it; a rename carries that session over.
Backup and domain import move from a card in the middle of the domain
list to their own /backup page, one card each; the handlers themselves
are unchanged, only the page the import form renders its errors on.
The domain page gains a "Sending server settings" card (server, port,
encryption) so a client can be configured without reading the docs; 587
is listed only when SUBMISSION_ENABLE is true for this deployment, which
is a deploy-time flag the panel cannot verify at runtime.
Client-side (static/panel.js, no libraries): Copy buttons on the values
that get carried elsewhere (DKIM record, new application credentials,
server name), and the Addresses field is hidden while the address mode is
wildcard, where the server ignores it.
Verified in a container on the dev server: setup, login, every page's
nav and active item, domain and application creation, all account-form
paths including cross-session invalidation, import errors, full backup
download. gofmt/vet/test/docker build green.

Security headers and setup-token docs were already decided but had no
concrete implementation phase; also mark A.1 rate-limit and CI test
workflow as done since they landed in recent commits.
A.2: headers emitted from the panel, not reverse-proxy — keep proxy config
minimal and hard to break, push complexity into the service.
A.5: keep stdout as the base setup-link delivery per spec; document the
/data/setup-token file as a more secure alternative for centralized-logging
setups.
Resolves plan item A.1 (option б): login/setup rate-limiting used
RemoteAddr only, which behind the default reverse proxy is the proxy's own
address, making the limiter effectively global and enabling a lockout-DoS.
Now, when the request's direct peer matches the new TRUSTED_PROXY_CIDR list
(comma-separated CIDRs, env, empty by default), the last X-Forwarded-For
entry is used instead, giving a real per-client limit. Unset behaviour is
unchanged.

Fold user feedback into a new Phase 12 covering the panel's UX gaps:
structural nav header on every page with active-state highlighting,
an account settings page for admin login/password, a dedicated
backup/migration page split from domain import, connection settings
on the domain page, copy-to-clipboard for values meant to be pasted
elsewhere, hiding the unused addresses field in wildcard mode, and
moving the Reload button to the new /status landing page (Phase 13,
renumbered from 12).
Adds a new agreed-upon phase covering /status (supervisord processes,
Postfix queue, TLS cert expiry, milter sockets, PTR/FCrDNS check) and
per-domain DNS correctness status (DKIM/SPF-heuristic/DMARC) on the
domain page. Not part of v1.0 spec scope; scoped and agreed with the
user before implementation.

CHANGELOG.md now tracks version history (0.1.0 baseline); progress.md and
implementation-plan.md keep only live process and unfinished work (open
questions, optional 2.x.x phase O1) since phases 0-11 are fully closed and
already covered by git history and the changelog.

Bringing up the production Apache stack for real surfaced a latent bug
in the Phase 10 hardening: cap_drop: ALL with only NET_BIND_SERVICE/
CHOWN/SETUID/SETGID/DAC_OVERRIDE left the root startup phase unable to
chmod the /data dirs it had just chowned to the panel user (needs
CAP_FOWNER) or set their setgid bit (needs CAP_FSETID). The container
crash-looped on "chmod: Operation not permitted". Phase 10 never caught
this because its compose up hit a port conflict before full boot.
Add FOWNER and FSETID to cap_add and document what each capability is
for. Verified: container now starts clean under the hardened compose.

Capture conscious tradeoffs and hardening candidates that go beyond the
mandatory 7.6 requirements: reverse-proxy rate-limit keying, missing
security response headers, CSRF/SameSite stance, __Host- cookie prefix,
session/ops notes, and the gap that CI does not run go test. None are
compliance defects; each is a decide-later item.

Line-by-line audit of all 8 points of spec 7.6 against the code: full
compliance, no code changes required. Acceptance verified on the dev
server (image selfpost:p11): gofmt/vet/build/test green, docker build
ok, clean container start (all processes RUNNING, panel as non-root
uid 999, setup link + 0600 token, bogus token 404, unauth 303, healthz
200). Baseline v1.0 plan (phases 0->11) complete.

- deploy/docker-compose.yml: pinned-tag ghcr image, hardened (cap_drop ALL +
minimal cap_add, no-new-privileges, panel bound to 127.0.0.1 only). Apache
itself runs on the host (spec 10.5), fragment at deploy/apache/.
- Alternative reverse-proxy fragments: nginx (+certbot sidecar), Caddy
(automatic ACME), Traefik (+acme.json PEM extraction script).
- .github/workflows/release.yml: tag-triggered ghcr.io publish, version piped
from the git tag into both the binary ldflags and the image tag (spec 10.1).
- Closed a gap from Phase 1: logrotate was installed but never invoked;
wired up build/logrotate-mail.conf + logrotate-loop.sh + a supervisor
program (copytruncate, since postlogd holds mail.log open with nothing to
signal on rotation).
- README rewritten: site requirements checklist, reverse-proxy comparison,
DNS setup (server- vs domain-level), IP warmup, backup/restore vs domain
export/import, fixed-tag rationale, machine requirements.
