CHANGELOG.md

reviewed

··· 6 6 7 7 ## [Unreleased] 8 8 9 9 + ### Added 10 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 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 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 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 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 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 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 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 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 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 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 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 22 + 23 23 + ### Fixed 24 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 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 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 27 + 9 28 ### Changed 29 29 + - Extract config.go and message.go from cmd/relay/main.go (#264) 30 30 + - Extract background workers + delivery callback from main() — periodic goroutines, shutdown (#262) 31 31 + - 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. 32 32 + - 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) 33 33 + - 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) 34 34 + - 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 35 - License changed from MIT to AGPL-3.0-or-later 11 36 - Add SPDX-License-Identifier headers to all Go source files 12 37 13 38 ### Security 39 39 + - Remove DNS grace period and enforce DNS checks from first send (#263) 40 40 + - 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 41 - Add DID validation to admin handleMember endpoint (#16) 15 42 - Narrow OAuth scope from transition:generic to repo:email.atmos.attestation (#189) 16 43 - sec(account): SameSite=Strict blocks cookie after OAuth cross-site redirect — switch to Lax (#180)

··· 1 1 + # Mirror notice 2 2 + 3 3 + The repository at `tangled.org/scottlanoue.com/atmosphere-mail` is a 4 4 + **published mirror** of a private development repository. The two are 5 5 + kept in sync by `scripts/sync-tangled.sh`, which runs on demand (not on 6 6 + every commit). 7 7 + 8 8 + This file exists so anyone reading the public mirror knows what they 9 9 + are looking at and what is *not* visible. 10 10 + 11 11 + ## What is the same 12 12 + 13 13 + - All Go source code under `cmd/` and `internal/` 14 14 + - The lexicons and design docs under `lexicons/` and `docs/` 15 15 + - The Nix/Terraform infrastructure definitions under `infra/` 16 16 + - Tests, fixtures, and the AGPL-3.0 license 17 17 + 18 18 + If a reader builds the binary from this mirror and runs it, they 19 19 + get the same software the operator runs in production. 20 20 + 21 21 + ## What is scrubbed before publishing 22 22 + 23 23 + The sync script applies `git filter-repo` with the following rules: 24 24 + 25 25 + 1. **Internal hostnames replaced** with neutral substitutes. The 26 26 + operator's tailnet uses `*.internal.example` host names; these 27 27 + get rewritten to `*.internal` (e.g. `kafka-broker.internal`, 28 28 + `db.internal`, `ops.internal`). The substitution is mechanical and 29 29 + is applied to both file contents and commit messages. 30 30 + 2. **Internal IPs redacted.** Specific Tailscale-internal IPs are 31 31 + replaced with the literal `<internal-ip>`. 32 32 + 3. **AI co-author trailers removed.** Commit messages with 33 33 + `Co-Authored-By: ...claude...` or `...anthropic.com` lines have 34 34 + those lines stripped before publishing. The commit content is 35 35 + unchanged. 36 36 + 4. **Author normalization.** All commits show the same author 37 37 + (`Scott Lanoue <scott@lanoue.dev>`); historical aliases are 38 38 + collapsed via mailmap. Co-contributor commits, if and when they 39 39 + exist, will be additive — this rule normalizes the operator's own 40 40 + shifting email aliases, not third-party contributors. 41 41 + 5. **History squashed into phase commits.** Rather than mirroring 42 42 + every individual commit, the sync collapses runs of related work 43 43 + into a single descriptive commit per "phase." Each phase commit 44 44 + represents a coherent theme (e.g. `feat: integration test 45 45 + harness, outbound deliver-path verification, and multi-domain 46 46 + enrollment`). The full per-merge history lives on the private 47 47 + side; the public mirror gets the synthesized story. 48 48 + 49 49 + ## What is removed entirely 50 50 + 51 51 + Some paths are excluded from the mirror because they are operationally 52 52 + sensitive or inherently project-internal: 53 53 + 54 54 + - `scripts/` — the publishing script itself, plus repo automation 55 55 + helpers. The script's contents would partially undo the scrub list 56 56 + (e.g. a reader could see what hostnames are being substituted *to* 57 57 + what, which is strictly more information than not having the script 58 58 + at all). 59 59 + - `.claude/` — agent worktree caches and logs. 60 60 + - `.agent-skills.md` — internal collaboration notes. 61 61 + - A subset of `.gitea/workflows/` — specifically the deploy and 62 62 + ops-automation workflows (`relay-deploy.yml`, `ops-deploy.yml`, 63 63 + `relay-provision.yml`, the DNS-record manipulation workflows, and 64 64 + the Hetzner firewall workflow). These reveal infrastructure topology 65 65 + and credentials-handling patterns that the operator considers 66 66 + reasonable to defer until the project has more usage history. 67 67 + - The code-verification workflows (`go-tests.yml`, `govulncheck.yml`, 68 68 + `template-escape-lint.yml`, `sml-tests.yml`, `validate-sml.yml`) 69 69 + **are** published, so anyone can see how PRs get gated before merge. 70 70 + 71 71 + ## Sync cadence 72 72 + 73 73 + There is no SLA. The sync is run by the operator manually, generally 74 74 + when a coherent batch of work has accumulated. In practice that's 75 75 + been every few weeks during the alpha. The mirror **is delayed from 76 76 + production** — typically by hours to days, occasionally longer. 77 77 + 78 78 + ## Why this setup 79 79 + 80 80 + The relay project's mission is to lower the cost of running legitimate 81 81 + self-hosted email by pooling reputation across small operators. That 82 82 + mission is served by the source being inspectable, AGPL-licensed, and 83 83 + reproducible. It is **not** served by exposing operational secrets 84 84 + that would let an attacker degrade the relay's deliverability for 85 85 + everyone using it. 86 86 + 87 87 + The compromise reflected here — publish the source and the verification 88 88 + workflows, hold back the deploy automation — is a deliberate alpha- 89 89 + phase tradeoff. As the project gains more members and external 90 90 + contributors, the bar for "what's worth holding back" should naturally 91 91 + shift toward smaller. The operator intends to revisit periodically. 92 92 + 93 93 + ## Reporting issues 94 94 + 95 95 + For source code questions, use the `tangled.org` issue tracker on this 96 96 + repo. For deliverability or operational issues with the relay itself, 97 97 + mail `postmaster@atmos.email`.

··· 1 1 + # Offsite Restic Backups — Activation Runbook 2 2 + 3 3 + Atmosphere Mail's local restic backup runs every 6 hours on each VPS, 4 4 + writing snapshots to a Hetzner Cloud Volume attached to that same VPS. 5 5 + Hetzner-native VPS snapshots (PR #337) cover the case where the volume 6 6 + itself fails. This document covers the third layer: an offsite copy that 7 7 + survives Hetzner-account-level loss (account suspension, region-wide 8 8 + incident, billing failure). 9 9 + 10 10 + The `services.restic-offsite-copy` NixOS module ships dormant. Activate 11 11 + it per host using the runbook below. 12 12 + 13 13 + ## 1. Pick a destination 14 14 + 15 15 + Three reasonable destinations, in increasing order of operational 16 16 + independence from Hetzner: 17 17 + 18 18 + | Destination | Cost (5GB) | Vendor-loss protection | Setup effort | 19 19 + |---|---|---|---| 20 20 + | **SFTP via Tailnet** to a homelab host | $0 | Partial — homelab + Hetzner are independent failure domains | Lowest — SSH key only | 21 21 + | **Hetzner Storage Box** (BX11) | ~€3.20/mo for 1TB | None — same Hetzner account | Low — Robot console | 22 22 + | **Backblaze B2** | ~$0.03/mo at 5GB | Full — separate vendor | Medium — new account | 23 23 + 24 24 + Recommendation: **SFTP via Tailnet to a homelab host** for the immediate 25 25 + gap (geographic + vendor independence at zero marginal cost), graduating 26 26 + to **B2 later** once the cooperative grows past a handful of members. 27 27 + 28 28 + ## 2. Provision credentials 29 29 + 30 30 + ### Option A: SFTP via Tailnet (recommended for now) 31 31 + 32 32 + On the destination host (e.g. `big-nix`): 33 33 + 34 34 + ```bash 35 35 + # Create the backup directory and a dedicated user 36 36 + sudo useradd -m -d /srv/atmos-backup atmos-backup 37 37 + sudo install -d -o atmos-backup -g atmos-backup -m 0700 /srv/atmos-backup/relay 38 38 + sudo install -d -o atmos-backup -g atmos-backup -m 0700 /srv/atmos-backup/ops 39 39 + 40 40 + # Generate an SSH key on each VPS, then authorize them here. 41 41 + # (Run on atmos-relay and atmos-ops separately to get two pubkeys.) 42 42 + sudo -u atmos-backup mkdir -p /srv/atmos-backup/.ssh 43 43 + sudo -u atmos-backup tee -a /srv/atmos-backup/.ssh/authorized_keys < /tmp/relay-and-ops.pub 44 44 + sudo chmod 600 /srv/atmos-backup/.ssh/authorized_keys 45 45 + ``` 46 46 + 47 47 + On each VPS (atmos-relay, atmos-ops), generate the SSH key the offsite 48 48 + job will use: 49 49 + 50 50 + ```bash 51 51 + ssh root@atmos-relay 'ssh-keygen -t ed25519 -N "" -f /root/.ssh/restic-offsite -C atmos-relay-offsite' 52 52 + ssh root@atmos-relay 'cat /root/.ssh/restic-offsite.pub' # paste into authorized_keys above 53 53 + ``` 54 54 + 55 55 + Then capture the destination host's SSH host key for pinning: 56 56 + 57 57 + ```bash 58 58 + ssh-keyscan -t ed25519 kafka-broker.internal > /tmp/restic-offsite-known-hosts 59 59 + ``` 60 60 + 61 61 + Store that file's contents as a sops secret named 62 62 + `restic_offsite_known_hosts` (one per host in `relay.yaml` / `ops.yaml`). 63 63 + 64 64 + ### Option B: Backblaze B2 65 65 + 66 66 + 1. Create a Backblaze account, then create a private bucket per host: 67 67 + `atmos-relay-backup` and `atmos-ops-backup`. 68 68 + 2. Create an Application Key scoped to those buckets with `read+write` 69 69 + capabilities. Save the `keyID` and `applicationKey`. 70 70 + 3. Add to sops: 71 71 + 72 72 + ```bash 73 73 + sops infra/secrets/relay.yaml 74 74 + # add: 75 75 + # restic_b2_account_id: <keyID> 76 76 + # restic_b2_account_key: <applicationKey> 77 77 + 78 78 + sops infra/secrets/ops.yaml 79 79 + # same keys 80 80 + ``` 81 81 + 82 82 + ## 3. Wire the sops template 83 83 + 84 84 + Add to the host's NixOS config (in `default.nix` for atmos-relay, or 85 85 + `atmos-ops.nix` for atmos-ops) inside the existing sops block: 86 86 + 87 87 + ```nix 88 88 + # For B2: 89 89 + sops.secrets.restic_b2_account_id = { 90 90 + owner = "root"; group = "root"; mode = "0400"; 91 91 + sopsFile = ../secrets/relay.yaml; # or ops.yaml 92 92 + }; 93 93 + sops.secrets.restic_b2_account_key = { 94 94 + owner = "root"; group = "root"; mode = "0400"; 95 95 + sopsFile = ../secrets/relay.yaml; 96 96 + }; 97 97 + sops.templates."restic-offsite-env" = { 98 98 + owner = "root"; group = "root"; mode = "0400"; 99 99 + content = '' 100 100 + B2_ACCOUNT_ID=${config.sops.placeholder.restic_b2_account_id} 101 101 + B2_ACCOUNT_KEY=${config.sops.placeholder.restic_b2_account_key} 102 102 + ''; 103 103 + }; 104 104 + 105 105 + # For SFTP via Tailnet (no env vars needed; SSH key + known_hosts only): 106 106 + sops.secrets.restic_offsite_known_hosts = { 107 107 + owner = "root"; group = "root"; mode = "0400"; 108 108 + sopsFile = ../secrets/relay.yaml; 109 109 + }; 110 110 + ``` 111 111 + 112 112 + ## 4.
