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.

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.

Three HTMX-polled monitoring screens (spec 7.2.11-13): send log with
server-side domain/application filters and pagination, Postfix queue
(postqueue -p), and a mail.log tail. Fragment endpoints return HTML
snippets, not JSON (spec 7.1); all output is auto-escaped via
html/template (spec 7.6.7).
Adds store.QuerySendLog/CountSendLog/ListApplicationLogins,
postfix.Queue(), and logtail.TailLines (a point-in-time reverse read,
independent of the background follow loop). Verified on the dev server:
gofmt/vet/test green, docker build green, container e2e (filters,
60-row pagination, <script> escaping, real postqueue/mail.log output,
existing Reload button unaffected).

Implement the structured send log (spec 7.3), the project's highest-risk
component since a milter bug can break the relay itself.
- internal/milter: go-milter v0.4.1 journal-milter. Per-connection session
collects SASL login, From, recipients and Subject across callbacks and
writes one send_log "queued" row per (queue-id, recipient) at EOM
(spec 7.3.3). Monitoring only: callbacks return Continue/Accept, recorder
errors are logged never propagated, so it can never block mail.
- internal/logtail: polling mail.log tailer with rotation handling (inode
change / truncation), parses sent/deferred/bounced/expired by queue-id +
recipient and advances rows; background retention sweep prunes rows past
SEND_LOG_RETENTION_DAYS (default 90) at startup and every 6h.
- internal/store/sendlog.go: InsertQueued, UpdateStatus (case-insensitive
recipient match), DeleteSendLogBefore + status constants.
- cmd/panel: open the store once and share it across http/milter/tailer;
replace the journal/logtail stubs with the real roles.
- build/postfix-config.sh: bounded milter timeouts (15/15/30s) so a hung
milter also fails open in seconds, not the 300s default.
Fix found in-container: SASL login (app_login) was empty because go-milter
keys macros exactly as Postfix sends them, and multi-character macro names
arrive brace-wrapped ({auth_authen}); the SASL-less Phase 0 spike could not
observe this. Added a brace-tolerant macro lookup.
Verified on selfpost.example.com: gofmt/vet/unit tests green; container e2e
records rows with correct fields and advances status via the tailer; fail-open
confirmed for both an unreachable and a hung milter; retention prunes at start.
