### Added
10
+
- Queue.DeliverFunc injection point + dispatch lifecycle test (#228, installment 4). Production change: new `QueueConfig.DeliverFunc` field defaulting to the existing `deliverMessage` (real MX lookup + SMTP). Any caller that doesn't set the field keeps the original behavior — `cmd/relay/main.go` doesn't set it, so production is unchanged. New integration test `TestIntegration_QueueDispatchesViaDeliverFunc` injects a fake delivery function to assert the full lifecycle: SMTP submit → onAccept → Queue.Enqueue → Queue.Run() worker dispatches → injected DeliverFunc fires → onDelivery callback receives a "sent" terminal result. Closes the unit-test gap that previously could only be filled by mocking DNS or running a fake SMTP at the MX-lookup edge
11
+
- Multi-recipient + capacity pre-check tests added to the integration harness (#228, installment 3). Two new tests: (a) `TestIntegration_SMTPSubmit_MultiRecipient` drives a 3-recipient submission, asserts all three round-trip through Store + Queue, and pins the AggregateRecipientOutcomes contract (succeeded=3, failed=0, retryAll=false); (b) `TestIntegration_SMTPSubmit_CapacityPreCheckRejectsBatch` pins the #226 invariant — when `HasCapacity(len(to))` returns false, the WHOLE batch must be rejected with 451 BEFORE any Store.InsertMessage runs, preventing the duplicate-delivery scenario where M of N recipients persist then the client retries. Zero production code touched
12
+
- Suppression-list test layer added to the integration harness (#228, installment 2). Two new tests in `internal/relay/integration_smoke_test.go`: (a) `TestIntegration_SMTPSubmit_SuppressionDropsRecipient` pre-inserts a suppression and submits to one suppressed + one clean recipient, asserting only the clean one round-trips through Store + Queue while the suppressed one drops silently — the exact behavior `cmd/relay/main.go` lines 648-681 implements; (b) `TestIntegration_SMTPSubmit_AllSuppressedRejects` covers the boundary where every RCPT TO has a live suppression and the SMTP submit returns 550. Zero production code touched
13
+
- First installment of the cross-component SMTP integration harness (#228). New `internal/relay/integration_smoke_test.go` wires real `Store` + `RateLimiter` + `Queue` + `SMTPServer` together — the same shape `cmd/relay/main()` builds — and asserts that one SMTP submission flows all the way from AUTH → RCPT → DATA → onAccept → `Store.InsertMessage` → `Queue.Enqueue`. Acts as a tripwire for cross-component contract drift (Queue.Enqueue signature, MemberLookupFunc shape, OnAcceptFunc parameters) ahead of the larger #217 cmd/relay refactor. Zero-risk additive change — no production code touched. Subsequent PRs will layer in suppression, partial-delivery aggregation, real fake-SMTP delivery, and admin enroll-approval → SMTP-AUTH-with-new-credentials
14
+
- Content spray detection promoted from shadow → live enforcement (#196). The fingerprint pipeline (sha256 over normalized subject+body, `relay_events.content_fingerprint` index, `Store.GetSameContentRecipientsSince` query, Osprey `same_content_recipients_last_hour` enrichment) was already wired; this PR removes the `shadow:` prefix from the labels and adds a `DeclareVerdict(verdict='reject')` to `ExtremeContentSpray`. Two-tier policy: `ContentSpray` (15+ same-content recipients/hr → 12h observational `content_spray` label, no verdict) and `ExtremeContentSpray` (50+ → 3-day `content_spray_extreme` label + 550 reject). Bake-in audit before promotion confirmed zero `shadow:content_spray*` firings against Osprey's `entity_labels` table across the entire shadow window. Two new test fixtures under `osprey/tests/fixtures/` cover the moderate (label-only) and extreme (label+reject) paths. Privacy: only the sha256 hash + scalar count cross the relay→Osprey boundary; recipient addresses and body content stay relay-side
15
+
- Periodic PLC tombstone check (#248). New `internal/scheduler.TombstoneChecker` runs daily, polls `plc.directory` for every did:plc with active labels, and negates all of a DID's labels when PLC returns 410 Gone (the canonical tombstone signal). Closes the gap where a member retiring their atproto identity post-enrollment would leave Atmosphere Mail vouching for a non-existent account indefinitely. did:web is skipped (no PLC). 5xx and non-410 4xx responses are explicitly NOT misread as tombstones — labels stay live across PLC outages. Defaults: 24h interval, 500ms between requests (= 2 req/s, fits PLC fair-use). Configurable via `plcTombstoneCheckInterval` and `plcRequestDelay`; set the interval `<=0` to disable. Exposes `labeler_plc_status_checks_total{result=ok|tombstoned|err}` and `labeler_plc_status_last_run_unix_seconds` on `/metrics`
16
+
- New `services.restic-offsite-copy` NixOS module (`infra/nixos/restic-offsite.nix`) that copies the local restic repo to an offsite destination on a daily timer. Backend-agnostic (B2, S3, SFTP-via-Tailnet, REST). Imported into both `atmos-relay` and `atmos-ops` configs but ships dormant (`enable = false`) — activation requires picking a destination and provisioning credentials per `docs/offsite-backups.md`. Closes the failure mode where a single Hetzner volume failure destroys both data and "backups" simultaneously (#221)
17
+
- Hetzner-native daily snapshots enabled on both `atmos-relay` and `atmos-ops` VPS resources (terraform `backups = true`). 7-day retention, +20% server cost (~€3.20/mo for both). Survives volume failure that would destroy local restic backups (#221) since snapshots live on Hetzner's separate storage cluster. Apply via the `relay-provision` workflow with `action=apply` after merge (#231)
18
+
- New `GET /admin/sender-reputation?did=&since=` admin endpoint returning per-DID rolling-window send/bounce/complaint counts plus current suspension state. Reads from `Store.SenderReputation` over relay_events + inbound_messages (FBL-ARF) + members.status. Default window is 30 days, capped at 365. Sets up the data path for the labeler's clean-sender computation in #245 (#244)
19
+
- /account/manage shows a "Publish attestation" form for any signed-in domain whose attestation_rkey is empty — lets members who completed enrollment but never ran the publish OAuth round-trip self-recover without operator action (#235)
20
+
- End-to-end enrollment-funnel integration test covering wizard finish → atomic publish redirect → callback. Pins both the success path (PutRecord lands, SetAttestationPublished stamps, credentials render) and the publish-failure path (credentials preserved, /account/manage retry link present). Closes the test gap that let #233 ship (#237)
21
+
- /account/manage renders a "Label status" section showing the live verified-mail-operator and relay-member state from the labeler XRPC, plus a re-publish form when labels are missing despite a published attestation. Closes the silent-failure mode where attestation_rkey is set but the labeler rejected DKIM, leaving SMTP sending broken with no diagnostic on the manage page (#240)
22
+
23
+
### Fixed
24
+
- Osprey rules now actually deploy on merge. Previously the `osprey-rules-sync` systemd service had `RemainAfterExit=true`, so it ran exactly once per atmos-ops boot and any rule change merged after that silently never reached the running worker. Discovered when verifying #196's content_spray promotion — the production worker (image from 2026-04-22) had only 13 of 14 rule files, and content_spray.sml had never loaded, meaning the entire shadow-mode bake-in was a no-op. This PR (a) drops `RemainAfterExit=true` so the service is freely re-runnable, (b) adds a content-hash compare so the worker only restarts when rules actually changed, (c) adds an hourly systemd timer for defense-in-depth autosync, (d) adds `osprey/**` to ops-deploy.yml's path filter so merges trigger an immediate deploy, (e) adds an explicit `systemctl start osprey-rules-sync.service` step to the deploy workflow so rule changes propagate within the deploy window rather than waiting up to an hour for the timer (#251)
25
+
- ops-deploy.yml path filter no longer misses transitive labeler dependencies — added `internal/{config,did,dns,domain,jetstream,label,loghash,scheduler,server,store}/**` and `infra/nixos/**`. PR #340 (DID hardening) merged but didn't deploy to atmos-ops because the only filter entries were `cmd/label{,er}/**` and a non-existent `internal/labeler/**`; the labeler ran stale code for ~17 minutes until #341 happened to touch `cmd/labeler/main.go` and finally tripped the filter. Same gap fixed in relay-deploy.yml (added `internal/did/**`, `internal/loghash/**`). Comment in both workflows tells future devs to re-derive via `go list -deps` whenever a new internal package is introduced (#249)
26
+
- Account UX papercuts on /account/* navigation. (a) Round-tripping back to /account from any sub-page (e.g. /account/deliverability) no longer re-prompts a signed-in member for sign-in — handleLanding now redirects to /account/manage when a valid recovery cookie is present, falling through to the form on stale cookies so there's no redirect loop. (b) /account/deliverability collapsed the doubled-up topnav stack (publicLayout's "← home" plus a redundant "← Account" breadcrumb) into a single nav band — the parent-link is preserved as an inline "← Back to account" beneath the lede (#239)
27
+

### Changed
29
+
- About §1 marketing copy now correctly states the relay is AGPL-3.0-licensed, not MIT (#227). Surface had been stale since the license switch landed earlier in this Unreleased window.
30
+
- Privacy policy §4 and About §3 now accurately distinguish public atproto labels (verified-mail-operator, relay-member, signed and network-visible via labeler.atmos.email) from internal-only Osprey reputation signals (highly_trusted, auto_suspended, used for SMTP-time enforcement only). Prior copy claimed Osprey labels were atproto-published, which was never wired in code (#243)
31
+
- Atomic enroll+publish: the wizard now kicks the publish-OAuth round-trip automatically on /enroll/verify success and reveals credentials only on the post-publish callback. Closes the funnel cliff that stranded richferro.com and self.surf — closing the tab after seeing credentials is now harmless because the attestation is already on the PDS (#234)
32
+
- Soften the credentials-page warning copy: replace "the only remedy is to re-enroll" with a /account self-service rotation reference, since `/recover/start` (now `/account/start`) lets members rotate the API key without re-enrolling (#236)
10
33
- License changed from MIT to AGPL-3.0-or-later
11
34
- Add SPDX-License-Identifier headers to all Go source files

36
### Security
37
+
- harden(labeler): unified DID syntax validation (`internal/did.Valid`) replaces three diverging copies that disagreed on whether did:web could contain `%3A` port-encoding — the admin and diagnostics endpoints would 400 on member DIDs that the labeler had already verified. Adds a 253-byte length cap to did:web (DNS hostname limit) where the prior label-side regex had no cap. Five label/manager.go log sites now redact DIDs via the new `internal/loghash` package. `PerDIDRateLimiter.Allow("")` now rejects empty DIDs up-front so a code path that loses the DID can't silently flood the global bucket via the implicit empty-string window. (#247)
14
38
- Add DID validation to admin handleMember endpoint (#16)
15
39
- Narrow OAuth scope from transition:generic to repo:email.atmos.attestation (#189)
16
40
- sec(account): SameSite=Strict blocks cookie after OAuth cross-site redirect — switch to Lax (#180)

# Offsite Restic Backups — Activation Runbook
2
+
3
+
Atmosphere Mail's local restic backup runs every 6 hours on each VPS,
4
+
writing snapshots to a Hetzner Cloud Volume attached to that same VPS.
5
+
Hetzner-native VPS snapshots (PR #337) cover the case where the volume
6
+
itself fails. This document covers the third layer: an offsite copy that
7
+
survives Hetzner-account-level loss (account suspension, region-wide
8
+
incident, billing failure).
9
+
10
+
The `services.restic-offsite-copy` NixOS module ships dormant. Activate
11
+
it per host using the runbook below.
12
+
13
+
## 1. Pick a destination
14
+
15
+
Three reasonable destinations, in increasing order of operational
16
+
independence from Hetzner:
17
+
18
+
| Destination | Cost (5GB) | Vendor-loss protection | Setup effort |
19
+
|---|---|---|---|
20
+
| **SFTP via Tailnet** to a homelab host | $0 | Partial — homelab + Hetzner are independent failure domains | Lowest — SSH key only |
21
+
| **Hetzner Storage Box** (BX11) | ~€3.20/mo for 1TB | None — same Hetzner account | Low — Robot console |
22
+
| **Backblaze B2** | ~$0.03/mo at 5GB | Full — separate vendor | Medium — new account |
23
+
24
+
Recommendation: **SFTP via Tailnet to a homelab host** for the immediate
25
+
gap (geographic + vendor independence at zero marginal cost), graduating
26
+
to **B2 later** once the cooperative grows past a handful of members.
27
+
28
+
## 2. Provision credentials
29
+
30
+
### Option A: SFTP via Tailnet (recommended for now)
31
+
32
+
On the destination host (e.g. `big-nix`):
33
+
34
+
```bash
35
+
# Create the backup directory and a dedicated user
36
+
sudo useradd -m -d /srv/atmos-backup atmos-backup
37
+
sudo install -d -o atmos-backup -g atmos-backup -m 0700 /srv/atmos-backup/relay
38
+
sudo install -d -o atmos-backup -g atmos-backup -m 0700 /srv/atmos-backup/ops
39
+
40
+
# Generate an SSH key on each VPS, then authorize them here.
41
+
# (Run on atmos-relay and atmos-ops separately to get two pubkeys.)
42
+
sudo -u atmos-backup mkdir -p /srv/atmos-backup/.ssh
43
+
sudo -u atmos-backup tee -a /srv/atmos-backup/.ssh/authorized_keys < /tmp/relay-and-ops.pub
44
+
sudo chmod 600 /srv/atmos-backup/.ssh/authorized_keys
45
+
```
46
+
47
+
On each VPS (atmos-relay, atmos-ops), generate the SSH key the offsite
48
+
job will use:
49
+
50
+
```bash
51
+
ssh root@atmos-relay 'ssh-keygen -t ed25519 -N "" -f /root/.ssh/restic-offsite -C atmos-relay-offsite'
52
+
ssh root@atmos-relay 'cat /root/.ssh/restic-offsite.pub' # paste into authorized_keys above
53
+
```
54
+
55
+
Then capture the destination host's SSH host key for pinning:
56
+
57
+
```bash
58
+
ssh-keyscan -t ed25519 kafka-broker.internal > /tmp/restic-offsite-known-hosts
59
+
```
60
+
61
+
Store that file's contents as a sops secret named
62
+
`restic_offsite_known_hosts` (one per host in `relay.yaml` / `ops.yaml`).
63
+
64
+
### Option B: Backblaze B2
65
+
66
+
1. Create a Backblaze account, then create a private bucket per host:
67
+
`atmos-relay-backup` and `atmos-ops-backup`.
68
+
2. Create an Application Key scoped to those buckets with `read+write`
69
+
capabilities. Save the `keyID` and `applicationKey`.
70
+
3. Add to sops:
71
+
72
+
```bash
73
+
sops infra/secrets/relay.yaml
74
+
# add:
75
+
# restic_b2_account_id: <keyID>
76
+
# restic_b2_account_key: <applicationKey>
77
+
78
+
sops infra/secrets/ops.yaml
79
+
# same keys
80
+
```
81
+
82
+
## 3. Wire the sops template
83
+
84
+
Add to the host's NixOS config (in `default.nix` for atmos-relay, or
85
+
`atmos-ops.nix` for atmos-ops) inside the existing sops block:
86
+
87
+
```nix
88
+
# For B2:
89
+
sops.secrets.restic_b2_account_id = {
90
+
owner = "root"; group = "root"; mode = "0400";
91
+
sopsFile = ../secrets/relay.yaml; # or ops.yaml
92
+
};
93
+
sops.secrets.restic_b2_account_key = {
94
+
owner = "root"; group = "root"; mode = "0400";
95
+
sopsFile = ../secrets/relay.yaml;
96
+
};
97
+
sops.templates."restic-offsite-env" = {
98
+
owner = "root"; group = "root"; mode = "0400";
99
+
content = ''
100
+
B2_ACCOUNT_ID=${config.sops.placeholder.restic_b2_account_id}
101
+
B2_ACCOUNT_KEY=${config.sops.placeholder.restic_b2_account_key}
102
+
'';
103
+
};
104
+
105
+
# For SFTP via Tailnet (no env vars needed; SSH key + known_hosts only):
106
+
sops.secrets.restic_offsite_known_hosts = {
107
+
owner = "root"; group = "root"; mode = "0400";
108
+
sopsFile = ../secrets/relay.yaml;
109
+
};
110
+
```
111
+
112
+
## 4. Enable the module
113
+
114
+
In the same file:
115
+
116
+
```nix
117
+
services.restic-offsite-copy = {
118
+
enable = true;
119
+
sourceRepo = "/var/lib/atmos-backup/restic-repo";
120
+
121
+
# B2:
122
+
destRepo = "b2:atmos-relay-backup:atmos-relay";
123
+
environmentFile = config.sops.templates."restic-offsite-env".path;
124
+
125
+
# OR — SFTP via Tailnet:
126
+
destRepo = "sftp:atmos-backup@kafka-broker.internal:/srv/atmos-backup/relay";
127
+
sshKnownHostsFile = config.sops.secrets.restic_offsite_known_hosts.path;
128
+
};
129
+
```
130
+
131
+
(Pick exactly one `destRepo` per host — comment out the other.)
132
+
133
+
## 5. Deploy + verify
134
+
135
+
```bash
136
+
# Deploy via Gitea Actions ops-deploy / relay-deploy workflow
137
+
# (don't bypass CI — let the deploy run the standard path).
138
+
139
+
# After deploy, on the VPS:
140
+
ssh root@atmos-relay 'systemctl list-timers restic-offsite-copy'
141
+
ssh root@atmos-relay 'systemctl start restic-offsite-copy.service'
142
+
ssh root@atmos-relay 'journalctl -u restic-offsite-copy.service --no-pager | tail -50'
143
+
144
+
# First run initializes the destination repo. You should see:
145
+
# "Destination repo ... not initialized; initializing"
146
+
# "created restic repository ... at <destRepo>"
147
+
# "Copying snapshots from ... to ..."
148
+
# <snapshot count>
149
+
# "Offsite copy complete"
150
+
151
+
# Verify offsite contents (B2):
152
+
ssh root@atmos-relay '
153
+
source <(grep ^B2_ /run/secrets/.../restic-offsite-env)
154
+
export B2_ACCOUNT_ID B2_ACCOUNT_KEY
155
+
restic --repo b2:atmos-relay-backup:atmos-relay \
156
+
--password-file /root/.restic-password \
157
+
snapshots
158
+
'
159
+
160
+
# Verify offsite contents (SFTP):
161
+
ssh root@atmos-relay '
162
+
restic --repo "sftp:atmos-backup@kafka-broker.internal:/srv/atmos-backup/relay" \
163
+
--password-file /root/.restic-password \
164
+
snapshots
165
+
'
166
+
```
167
+
168
+
The timer fires daily at 02:00 UTC (with up to 1h randomized delay).
169
+
170
+
## Recovery drill
171
+
172
+
Once a quarter, restore a snapshot to a scratch directory and verify:
173
+
174
+
```bash
175
+
# From atmos-relay:
176
+
mkdir /tmp/restore-test
177
+
restic --repo <destRepo> --password-file /root/.restic-password \
178
+
restore latest --target /tmp/restore-test
179
+
sqlite3 /tmp/restore-test/var/lib/atmos-backup/dumps/relay.sqlite "SELECT COUNT(*) FROM members"
180
+
# ... compare against live `relay.sqlite`'s member count ±drift since snapshot
181
+
rm -rf /tmp/restore-test
182
+
```
183
+
184
+
If the count looks wildly wrong, the snapshot is suspect — investigate
185
+
`backupPrepareCommand` in `default.nix` and the source SQLite hot-backup
186
+
output before the next quarterly drill.
187
+
188
+
## Pricing note (B2 path)
189
+
190
+
5GB stored = ~$0.03/mo storage. Daily copies of incremental data ~50MB
191
+
each = ~$0.0006/day in egress (Hetzner egress bills separately and is
192
+
generous up to 20TB on cpx21 — well below). Total <$0.05/mo all-in for
193
+
the foreseeable cooperative size.

# Why this exists (#221):
7
+
# The local restic backups on atmos-relay and atmos-ops live on the

# same Hetzner Cloud Volume as the data they back up, with the

# `enable = true` only after the destination is provisioned and
28

# credentials are in sops. No credential reference is made when
29

# `enable = false` — sops never sees a missing-key error.

8
+
// cmd/relay refactor). It wires real Store + RateLimiter + Queue
9
+
// + SMTPServer together — the same wiring main() builds — and proves
10

// that an SMTP submission lands in both the store AND the queue.
11

// The point is not to reimplement main()'s onAccept (that has 250+
13
+
// lines of suppression / DKIM / Osprey policy / partial-delivery
14
+
// aggregation logic, all unit-tested in their own files). The point
15
+
// is to establish a tripwire for the WIRING: if any of the cross-
16
+
// component contracts drift (Queue.Enqueue's signature, MemberLookupFunc's
17
+
// signature, OnAcceptFunc's parameter list), this test breaks loudly
18
+
// rather than silently changing main()'s behavior.
19
+
//
20
+
// Subsequent #228 PRs will:
21
+
// - layer in suppression-list checks
22
+
// - swap the fake delivery for a real test SMTP target
23
+
// - add the partial-delivery aggregation assertion
24

// - cover admin enroll-approval → SMTP-AUTH-with-new-credentials
