Before/after on DNS2 (`journalctl -u caddy --since "5 minutes ago" | grep health_checker.active | wc -l`): **before = ~30 entries / 5min** (active probe every 10s, all failing); **after = 0 entries / 5min**. Live-verified: `caddy validate` succeeded (after removing `.bak` file that caused `ambiguous site definition`), Caddy reloaded via `caddy-apply`, route `arch.sami → 100.120.159.34:5000` still active in admin API (verified via `curl http://localhost:2019/config/apps/http/servers/srv0/routes` — `health_uri: None, health_interval: None` confirms the block is gone). Container `dashcaddy-api Up About an hour (healthy)` (no restart needed — only Caddyfile changed, not container). Live HTTP smoke all green: `https://status.sami=200`, `https://dashcaddy.net=200`, `https://ca.sami=200`, `https://status.sami/api/health=401` (auth-gated, expected).

Backup deleted (would have caused site-definition ambiguity on next Caddy reload). Git: change lives only in DNS2's `/etc/caddy/sites/arch.sami` (the `/etc/caddy` git repo `.gitignore` excludes `sites/` per design — only the main `Caddyfile` is tracked).

No feature code + may import a provider directly — registry only. Provider contract methods: + getStatus, listDevices, listPeople, createInvite, revokeInvite, blockPerson, + unblockPerson, removePerson, revokeDevice, syncAccess, whois, configureDns. + Tailscale provider wraps existing tailscale-coord.js + tailscale-manager.js. + Registry defaults to inactive until the wizard connects one. Tests: registry + resolution, capability flags, error mapping. Files: `src/network/*.js`, + `__tests__/network-registry.test.js`, `__tests__/network-provider-tailscale.test.js`. + +### DC-141: People store + routes (`routes/network-people.js`) +- **status:** todo +- **details:** people.json atomic store (invite-store pattern), CRUD routes under + `/api/v1/network/people`, admin-protection (`protectedAt`), last-admin guard + `assertNotLastAdmin()` exported for reuse. Sync endpoint merging provider users + into people. Tests: store CRUD, route contract, guard (cannot block/remove + last admin), sync merge idempotency. + +### DC-142: Tailscale invites (link-first) via provider +- **status:** todo +- **details:** POST/GET/DELETE `/api/v1/network/invites` calling provider + createInvite/revokeInvite. Tailscale: user-invites API, email optional — + inviteUrl is the artifact (share-text pre-formed sentence, copy button, + navigator.share, opt-in email checkbox; never log raw invite URLs to console). + Reuse DC-085 share pattern. Tests: route contract with mocked provider, + no-raw-token-in-logs assertion. + +### DC-143: Block / unblock / remove person + revoke device +- **status:** todo +- **details:** POST `/network/people/:id/block|unblock|remove`, + `/network/devices/:id/revoke`. Orchestrates: provider calls, session kill + (existing auth store), access-map purge/restore, audit log entries. Block must + be fully reversible (snapshots pre-block grants). Remove deletes devices + + person record. Tests: orchestration order (mocked provider), reversibility, + last-admin guard integration, audit entries written. + +### DC-143 cleanup note: access map module itself is DC-145. + +### DC-144: Groups (DashCaddy-side) + resources +- **status:** todo +- **details:** groups in people-store (array on person), group CRUD routes, + resource model (services registry projection + manual entries), per-resource + `sensitive` flag. No Tailscale-group mapping — ever (free plan caps 3; compiled + rules are per-user). Tests: group CRUD, resource projection, sensitive flag + validation. + +### DC-145: Access map store + grid API +- **status:** todo +- **details:** `network-access.json` grants store, bulk GET/PUT + `/network/access` (whole-grid save, atomic), effective-access computation + (group grants + person overrides), change events for compiler subscription. + This file is the single source of truth. Tests: store, effective access + resolution (group + override precedence), atomic whole-grid save. + +### DC-146: Technitium integration +- **status:** todo +- **details:** Technitium HTTP API client (credential via credential-manager), + per-resource/per-device record upserts (idempotent), split-DNS configure when + provider capability present, verify-by-resolve after write, wizard check step. + Tests: API client with mocked HTTP, idempotent upsert, failure paths. + +### DC-147: CA naming + name constraint + install page hardening +- **status:** todo +- issued from existing DashCA (routes/ca.js): operator-named root (setup-time, + rename = guided re-trust), critical nameConstraints (permitted DNS subtree = + private TLD), leaf regression tests (SAN + serverAuth EKU + ≤398d), branded + install page with per-OS steps incl. iOS enable-trust second step + fingerprint + + Android native-app caveat, encrypted root-key backup step (passphrase + + checksum). Tests: parse issued cert and assert constraint/SAN/EKU/validity; + install-page content checks. + +### DC-148: Tailscale ACL compiler + lockout guard +- **status:** todo +- **details:** access map → per-user HuJSON policy compiler. Hard rules: + last-active-admin must keep access to the DashCaddy host resource; host device + keeps egress; dry-run (ACL preview/test) before every push; last-known-good + policy retained for rollback; post-push hash stored, pre-push hash compare → + drift banner on mismatch. Provider.syncAccess(tailscale) uses this. Tests: + golden-policy cases, lockout adversarial cases (each rule), drift detection, + preview-failure refusal to push. + +### DC-149: WireGuard provider — hub management +- **status:** todo +- **details:** `providers/wireguard.js`: wg-quick iface `dcnet0`, address pool + 10.d.c.0.0/16 stable assignment, keygen on hub, peer store, systemd unit + if missing. All execFile-mocked in tests. Tests: pool assignment stability, + peer add/remove, unit generation, error paths (missing wg binary). + +### DC-150: WireGuard invites (QR) + client config +- **status:** todo +- **details:** one-time token (7d TTL, single-use) → redemption page rendering + client config + QR (qrencode -t ansiutf8 → pre? no: PNG served) with Address, + DNS=Technitium hub IP, AllowedIPs = private zone only (split tunnel). Private + key shown once, never stored server-side. Tests: token lifecycle, config + template correctness (allowed-ips, DNS), single-use enforcement, expiry. + +### DC-151: WireGuard firewall matrix (nftables) +- **status:** todo +- **details:** per-resource nft sets (net_dc_res_), peer IPs per grant, + transactional apply (build temp ruleset → `nft -c` → `nft -f` → verify → + rollback file), host admin ports restricted to admin peers. Tests: ruleset + golden text, transactional failure injection (nft -c fails → no apply), + verify-step failure, admin-port isolation. + +### DC-152: Setup wizard + status page +- **status:** todo +- **details:** mode pick → credentials/endpoint → private domain pick + (.internal default, home.arpa, custom+warning) → provider connect + sync → + Technitium check → CA naming (locked-in warning) → first admin person. + Status page: who's online, recent connections (provider status + DashCaddy + connection log).

This is enforced +by the provider abstraction (DC-140) — no feature module may call a provider +directly. + +## 2. Core concepts and stores + +- **Person** — a human. `people.json` (atomic JSON store, same pattern as + invite-store/user-store). Fields: `id`, `displayName`, `providerUserId` + (Tailscale user id or WG pubkey identity), `groups[]`, `status: + active|blocked|removed`, `devices[]`, `createdAt`, `protectedAt` (admin guard). +- **Device** — one machine. Belongs to a person. `keyId` (TS device id / WG peer + pubkey), `name`, `ip` (tailnet IP), `online`, `lastSeen`, `os`. +- **Group** — named bundle of people, DashCaddy-side only (UI concept). Free + Tailscale plans cap ACL groups at 3 — therefore **DashCaddy groups never map + to Tailscale groups**; compiled ACLs reference users directly. +- **Resource** — an app or device reachable by name. `plex.internal`, `nas.internal`. + Derived from the existing services registry + manual entries. +- **Access map** — groups/people × resources grid. Single source of truth. + `network-access.json`: `{ grants: [{ principal: {type:'person'|'group', id}, resource: 'plex', allowed: bool }] }`. + This file, not Tailscale state, is authoritative. + +## 3.

Feature +modules check capabilities and degrade cleanly (e.g. WireGuard mode skips the +split-DNS API step and writes Technitium directly). + +**Existing routes untouched.** `routes/tailscale.js` / `tailscale-admin.js` keep +working as-is; the new `routes/network.js` + `src/network/` are additive. + +## 4. Enforcement — two layers + +**Layer 1: network.** The access map compiles to provider rules. +- Tailscale: HuJSON policy with per-user src entries (never groups), `dst` as + `host:port` per resource. DashCaddy host always keeps an explicit allow for + the admin. **Lockout guard** (hard rule, tested): refuse to push any policy + where (a) the last active admin person would lose access to the DashCaddy + host resource, or (b) the DashCaddy host device would lose egress. Use the + ACL preview/dry-run endpoint before every push; keep the last-known-good + policy body for one-click rollback. Store the policy hash after each push and + compare before the next — outside edits ⇒ drift banner, not silent overwrite. +- WireGuard: hub-and-spoke means everyone can reach the hub; per-resource + enforcement is a hub nftables matrix. One nft set per resource + (`net_dc_res_plex`), peer IPs added per grant. **Apply is transactional**: + build the full ruleset to a temp file, `nft -c` (check), swap atomically via + `nft -f`, verify with `nft list set`, roll back file kept. + +**Layer 2: app (forward_auth).** Shared across providers. +- Whois path: forward_auth asks DashCaddy which person owns the connecting + device (provider.whois), then checks the access map. Tailnet users get in + without a separate login. **Identity follows the device** — a shared device + grants the owner's access; documented in the UI. +- Step-up: resources flagged `sensitive` additionally require the existing + DashCaddy login + TOTP (reuse sso-gate). + +## 5. People lifecycle (DC-141, DC-144) + +- Invite = link-first (DC-085 pattern): inviteUrl is the artifact, email is an + opt-in checkbox, never logged raw to console. +- Block (reversible): expire device keys + deny at network layer + kill + DashCaddy sessions + mark person blocked. Unblock reverses all four. +- Remove: block semantics + delete provider devices + delete person record + + purge from access map. The last active admin can never be blocked/removed + (same guard as the ACL compiler — one shared `assertNotLastAdmin()`). + +## 6. Names — Technitium (DC-146) + +- Per-resource + per-device A/AAAA records → tailnet IPs, written via + Technitium HTTP API (credential in credential-manager, existing pattern). +- Split DNS: Tailscale mode uses the API when available; check + repair wizard + step. WireGuard mode: devices get Technitium's hub IP as their DNS entry in + the generated client config. +- Record writes are idempotent (upsert by name+type) and verified by resolve. + +## 7. Certificate authority (DC-147) + +Builds on the existing DashCA pipeline (routes/ca.js, DC-076). Changes: +- Root CN = operator-chosen name ("Ahmed Family Certificate Authority"), + captured at first setup, baked in; rename ⇒ guided re-trust flow (warn at + naming time, not after). +- Root gets a **critical nameConstraints extension** (permittedSubtrees + DNS:). Mark critical so non-understanding clients fail closed. +- Leaves ≤ 398 days, SANs always set, serverAuth EKU (iOS 13+ requirements) — + the existing openssl leaf path already complies; add regression tests that + parse the issued cert and assert all three. +- Branded install page at ca.: per-OS steps including **iOS's second + step** (enable trust in Settings → General → About → Certificate Trust + Settings), SHA-256 fingerprint for verification, and an Android note that + native apps ignore user CAs (browsers fine). +- Root key never leaves the host except through an explicit wizard step: + encrypted backup download ( passphrase-wrapped ) + checksum. + +## 8. WireGuard provider (DC-149–151) + +- Hub: `wg-quick` interface `dcnet0` managed by DashCaddy ( systemd unit + `dcnet-hub.service` if absent ), 10.D.C.0.0/16 address pool with stable + per-device assignment stored in people.json. +- Keygen on the hub; peer private keys exist only in the one-time invite + redemption (client config + QR). Server stores pubkeys only. +- Client config template: Address, DNS = Technitium hub IP, + AllowedIPs = private zone subnet only (split tunnel — normal internet + traffic never touches the hub). +- Invite redemption: one-time token → render config + QR (qrencode), page + auto-expires; token single-use, 7-day TTL. +- Firewall: nftables matrix (above). Server resources listen on the hub IP; + per-resource sets gate peer access. The host's own admin ports are NOT + exposed on dcnet0 except to admins. + +## 9. Setup wizard (DC-152) + +Single flow, mode pick first: +1. Mode: Tailscale (paste OAuth client secret or API key — surface expiry + warnings for API keys, ≤90-day; recommend OAuth client `tskey-client-`) or + WireGuard (port, endpoint hostname/IP). +2. Private domain pick (default `.internal`, `home.arpa` offered, custom with + "could become real later" warning). +3. Provider connect + health check + first sync. +4. Technitium zone + split-DNS check. +5. CA naming (locked-in warning) + root generation + install page link. +6. First person (the admin — protected). + +## 10. Non-goals (explicitly out of scope for this lane) + +- Headscale support. Subnet routers / LAN access. Time-limited access. +- Multi-hub HA. Client auto-updaters. Migration between modes with data + carry-over (documented manual path only — switching re-runs the wizard). + +## 11. Test strategy + +- Every new module: Jest unit tests with the same mock rigor as + tailscale-manager.test.js (no live network in tests). +- ACL compiler: golden-policy tests (map JSON → expected HuJSON), lockout-guard + adversarial cases (last-admin removal, host egress cut, drift detection). +- WG provider: execFile-mocked `wg`/`nft` binaries; ruleset built to temp and + compared as text; transactional-apply failure injection. +- forward_auth: route tests against the running supertest app (existing + __tests__/routes pattern), including shared-device semantics. +- After merge + deploy to the dev rig: live-curl every new route (the DC-048 + discipline — hermetic green is not production proof).

Note about user certificates

-

Android installs this as a "user" certificate. Some apps may not trust user certificates for security reasons. For full trust, you would need to install it as a system certificate (requires root access).

+

⚠️ Important Android caveat: browsers OK, native apps no

+

Android installs this as a user certificate. Browsers (Chrome, Firefox) will trust it for HTTPS — but most native apps ignore user CAs for security reasons, so they will keep showing certificate errors. There is no fix without installing the CA at the system level, which requires a rooted device. Plan browsers-first on Android.
