 - **prerequisite:** None. `caddy-upstream-watcher.js` already provides equivalent monitoring.
 - **result:** Shipped GLM-pending (Codex quota dead). 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). Watcher state for `100.120.159.34:5000`: `consecutiveFailures: 1905`, `lastError: "probe timeout"`, `status: down`, `dead: true` — correctly tracked in `/opt/dashcaddy/dashcaddy-api/data/caddy-upstreams.json`. 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). The dashcaddy source repo (`/root/dashcaddy`) carries only this BACKLOG.md documentation update on branch `dc/DC-084-arch-sami-caddy-healthcheck-removal`.
 - **Tests:** No source code change; existing `__tests__/caddy-upstream-watcher.test.js` 26/26 pass (baseline preserved). 2465/2465 repo tests pass (4 pre-existing billing test suites fail with `Cannot find module pdfkit` — unrelated to this change).
+# P7 — Private Network lane (DC-140 … DC-152)
+
+> Spec: `specs/PRIVATE-NETWORK-SPEC.md`. Parent feature: DashCaddy Private Network
+> (Tailscale mode v1 + WireGuard self-hosted mode). Ordered by dependency, not by
+> value. All commits judge-gated (min B).
+
+### DC-140: Network provider abstraction (`src/network/`)
+- **status:** todo
+- **owner:** (fleet)
+- **details:** `provider.js` (contract + JSDoc), `registry.js` (active provider +
+  capabilities), `errors.js` (ProviderError with code/retryable). 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
+  snapshots pre-block grants; unblock restores the AUTHORIZATION state (grants,
+  status, sessions) — Tailscale device keys, once expired, are irreversible and
+  require re-authentication (reauthRequired=true + user note); WireGuard peers
+  restore immediately. Remove deletes devices + person record. Tests: orchestration order (mocked provider), honest unblock
+  semantics (Tailscale: reauthRequired true + note; WireGuard: immediate
+  restore), last-admin guard integration, audit entries written.
+
+**Note (not a ticket):** the 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` at 10.53.0.1/16
+  (client pool 10.53.0.0/16, one /32 per device, stable assignment), HUB keypair
+  generated host-side, peer store (pubkeys only), systemd unit if missing,
+  net.ipv4.ip_forward=1 for hub-and-spoke, no NAT on dcnet0. 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. Client
+  keypair generated IN THE BROWSER via WebCrypto X25519 ONLY — NO fallback
+  algorithm; browsers lacking X25519 get an explicit unsupported-browser
+  failure. Server receives the public key only, registers the peer /32,
+  returns config
+  (Address, DNS=10.53.0.1, hub PublicKey, AllowedIPs=10.53.0.0/16 — a CIDR,
+  never a DNS zone). Config + QR rendered client-side; private key never
+  transits or rests on the server. Tests: token lifecycle, single-use
+  enforcement, expiry, server-rejects-private-key-posts, config template
+  correctness.
+
+### DC-151: WireGuard firewall matrix (nftables)
+- **status:** todo
+- **details:** per-resource nft sets (net_dc_res_<name>), peer IPs per grant,
+  transactional apply (build temp ruleset → `nft -c` → `nft -f` → verify →
+  rollback file), three-zone baseline: external-interface UDP listen-port accept
+  (NOT on dcnet0); dcnet0 local input = ICMP + admin ports from admin set only +
+  resource ports; dcnet0 forwarding = per-resource sets, peer-to-peer default
+  drop. 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). Reuse monitoring widget patterns. Tests: wizard step
+  contracts, status aggregation with mocked providers.

+### Added
+- **DC-161: Calendar widget + Radicale auto-wiring.** New top-bar calendar widget
+  (`status/js/calendar-widget.js`) showing upcoming appointments; settings modal for
+  adding CalDAV / ICS-feed sources with a Test-connection probe. Backend:
+  `routes/calendar.js` (`GET/POST/PUT/DELETE /api/v1/calendar/sources`,
+  `GET /api/v1/calendar/events`, `POST /api/v1/calendar/radicale/provision`,
+  `POST /api/v1/calendar/discover`), dependency-free RFC 5545 ICS parser with
+  bounded RRULE expansion (`src/calendar/ics-parser.js`), CalDAV REPORT client
+  over node:https (`src/calendar/caldav-client.js`). When Radicale is deployed
+  through the App Selector, the deploy hook auto-provisions htpasswd credentials
+  (pure-Node APR1 hash, verified byte-for-byte against `openssl passwd -apr1`)
+  and registers the calendar source — the widget connects with zero user input.
+  Manual bring-your-own sources (Radicale/Baikal/Nextcloud hosted elsewhere,
+  iCloud/Fastmail CalDAV, plain ICS feeds) wire in through the settings modal.
+  Codex judge: **grade B (round 5)** —
+  urn:ump:znykdi6ufm53sgnhkep7ghlda7aoo55nipghjtstlkpqqmxuv2zq.
+
+## [1.17.0] - 2026-10-07
+
+### Added
+- **DC-CATALOG-3: catalog deploys route through the shipdeck bridge.** The App Selector sends
+  `subdomain` to `POST /api/deploys/catalog`, which validates the label and forwards it to the
+  bridge; the route reads the bridge journal for service state instead of spawning a subprocess per
+  service.
+- **Composition-root e2e suite.** `__tests__/e2e-node/composition-root.e2e.test.js` boots the real
+  app via `createApp()`, mints a JWT, and probes each mounted route against a nonexistent control
+  path in the identical request shape, so a real mount is distinguishable from an unknown route.
+- **Shield route committed.** `routes/shield.js` (until now present only on the production host) is
+  tracked in git, mounted by `src/app.js`, and covered by `__tests__/shield-dc.routes.test.js`.
+
+### Fixed
+- **DC-160: catalog detail returned empty template metadata.** `routes/catalog.js` reads
+  `app.docker.*` from the catalog template instead of the hand-rolled category map.
+- **Deploy audit contract.** The catalog-deploy route calls
+  `auditLogger.log({action,resource,details,outcome,ip})` fire-and-forget — the same dependency
+  shape `src/app.js` injects — and the route test constructs that shape, so a divergence fails.
+- **Bridge response handling is total.** Any non-plain-object body (`null`, arrays, empty) is
+  coerced into the same failure shape as a non-JSON body, so no `body.ok` dereference can 500 or
+  report a false success.
+- **Subdomain labels.** Validation rejects leading and trailing hyphens and is length-bounded
+  (1-63 characters); the rejection table in the route suite covers both edges.
+- **Boot timeout kills its child, exercised.** The e2e boot timeout is parameterized and a real test
+  drives it against a child that never reports readiness, asserting the killed child's `SIGKILL`.
+- **Test port allocation.** The e2e child binds port 0 and reports the OS-assigned port, removing
+  the release-and-rebind race in the old `freePort` helper.
+
+### Notes
+- Pre-existing and unrelated: `__tests__/billing/invoice.test.js` fails identically at the release
+  base (`1fa5ba8`) because it bundles a stale `pdf.js 1.10.100`; the failing set is measured, not
+  assumed, and recorded in the release evidence.

+ *   - slug validation (bad ids rejected, DashCaddy-local strings only)
+ *   - duplicate create → 409
+ *   - 'Admin' cannot be renamed or deleted (409)

+ *   - GET / lists invites via provider; empty list when provider lacks
+ *     listInvites (capability degradation)
+ *   - POST / without sendEmail → deliveredVia 'manual' (default NO email)
+ *   - POST / with sendEmail:true + emailSent → deliveredVia 'email'
+ *   - POST / provider email failure (emailSent:false or email_send_failed
+ *     with link on the error) → deliveredVia 'failed', link still present
+ *   - DELETE /:id → 204; not_found maps to 404; bad_input maps to 400
+ *   - 503 + code provider_not_active when no provider is connected
+ *   - no raw token / 'uinv/' ever reaches the log mock (redaction)
+ * Hermetic — supertest against an in-process express app, mocked provider,
+ * no network.

+ *   - unblock restores grants, returns reauthRequired per provider type

+ * WireGuard invite redemption routes — DC-150.
+ *
+ * PUBLIC, unauthenticated mount (the invite token IS the proof, spec §8.5):

+ *   GET  /network/wg/redeem/:token   → self-contained redemption page
+ *                                      (browser X25519 keygen, spec §8.2)
+ *   POST /network/wg/redeem/:token   → redeem API: validates the one-time
+ *                                      token, registers the browser-generated
+ *                                      PUBLIC key, returns the client config
+ *
+ * Key-lifecycle invariants (NORMATIVE, spec §8.2):
+ *   - The client keypair is generated in the invitee's BROWSER via WebCrypto
+ *     X25519; the server receives ONLY the base64 public key.
+ *   - The private key never transits or rests on the server: it lives in the
+ *     page session, rendered into the config text + QR CLIENT-side.
+ *   - This module must never reference, accept, or emit a private key.
+ *
+ * The provider contract used here (DC-149, src/network/providers/wireguard.js):
+ *   - provider.redeemInvite(token) — single-use + 7d TTL, marks the token
+ *     used on success, throws on unknown/used/expired tokens.
+ *     (Note: the DC-149 provider has no separate getInvite peek; redeemInvite
+ *     is the validation primitive. Any failure there maps to 410 Gone.)
+ *   - provider.addPeer({ personId, deviceId, publicKey, name }) →
+ *     { address, allowedIps, dns, hubPublicKey, hubAddress, listenPort, ... }
+ *
+ * Middleware registration (NOT done here — src/utilities/middleware.js is
+ * drift-test guarded): export PUBLIC_REDEEM_PATH_PREFIX and add
+ *   { path: PUBLIC_REDEEM_PATH_PREFIX, prefix: true }   → PUBLIC_ROUTES
+ *   plus the CSRF excludedPaths entry for the POST.
+ * The CSRF skip is safe because the token is single-use, 7-day TTL, and the

+ *      { error: 'unknown-device' } + WWW-Authenticate header.
+ *   2. Host → resource: match the leading subdomain of the request host
+ *      against resource names via resourcesStore. Unmatched → 404
+ *      { error: 'unknown-resource' }.
+ *   3. accessStore.effectiveAccess({ type:'person', id, groups }) →
+ *      person overrides beat group union. Denied → 403
+ *      { error:'forbidden', resource, personId }.
+ *   4. Allowed + resource.sensitive → step-up: a valid DashCaddy session
+ *      (TOTP login) via sessionValidator. Valid → 200
+ *      { authenticated:'step-up', personId }; missing/invalid → 401
+ *      { error:'step-up-required', loginUrl:'/auth/login' }.
+ *   5. Allowed + non-sensitive → 200 { authenticated:'tailnet', personId,
+ *      deviceId } — tailnet users get in with no separate login.
+ *
+ * Allowed responses carry X-Forwarded-User + X-Forwarded-Person — the
+ * headers Caddy's forward_auth copies to the upstream request.
+ *
+ * Every outcome is audited:
+ *   { event:'forward_auth_allow'|'forward_auth_deny'|'forward_auth_step_up',
+ *     personId, resource, host }
+ * 'forward_auth_step_up' is used for BOTH the 200 step-up success and the

+ * note; WireGuard peers are re-generated server-side from the stored pubkey
+ * and reconnect immediately (reauthRequired: false, different note).

+/**
+ * NetworkProvider interface — the documented contract for DashCaddy
+ * Private Network providers (DC-140, specs/PRIVATE-NETWORK-SPEC.md §3).
+ *
+ * Everything above the provider (people, groups, resources, access map,
+ * forward_auth, Technitium names, the CA, the UI) is shared and talks to
+ * the network ONLY through this contract — never to a provider module
+ * directly. Resolution goes through src/network/registry.js.
+ *
+ * ## Capability flags
+ *
+ * `capabilities()` returns:
+ *   - invites        provider can mint invite URLs itself (TS user-invites /
+ *                    WG one-time token). When false, DashCaddy mints its own.
+ *   - splitDnsApi    provider exposes a split-DNS API (Tailscale does;
+ *                    WireGuard writes Technitium directly instead).
+ *   - perPeerFirewall provider enforces per-peer rules natively (WG nftables;
+ *                    Tailscale relies on ACLs, so false).
+ *   - selfHosted     no outside control-plane dependency (WG true, TS false).
+ *
+ * Feature modules MUST check capabilities and degrade cleanly.
+ *
+ * ## Methods (all async, all return plain JSON, all validated)
+ *
+ *   id() → 'tailscale' | 'wireguard'
+ *   capabilities() → { invites, splitDnsApi, perPeerFirewall, selfHosted }
+ *   getStatus() → provider health/summary (TS: local `tailscale status`;
+ *                 WG: `wg show dump` + iface state)
+ *   listDevices() → device list merged with local online state
+ *   listPeople() → provider users projected to
+ *                 { id, displayName, email, createdAt }
+ *   createInvite({ role, email? }) → { inviteUrl, id } — email is OPTIONAL;
+ *                 when omitted, the provider returns a link without sending
+ *                 (link-first, DC-085 pattern; never log inviteUrl raw)
+ *   revokeInvite(id) → { revoked: true }
+ *   blockPerson(userId) → reversible network-level block (TS: expire every
+ *                 device key owned by the user; WG: drop peer + deny set)
+ *   unblockPerson(userId) → reverse of blockPerson (TS: no-op at provider
+ *                 level, DashCaddy re-grants via syncAccess)
+ *   removePerson(userId) → delete provider devices + revoke invites
+ *   revokeDevice(deviceId) → expire/remove a single device's access
+ *   syncAccess(accessMap, resources) → compile + dry-run + push provider
+ *                 rules (hash-guarded). Injected per provider in later DCs
+ *                 (TS ACL compiler = DC-148; WG nftables = DC-150).
+ *   whois(ip) → which person owns the connecting device
+ *   configureDns({ zone, server }) → split-DNS setup when splitDnsApi
+ *
+ * ## Error contract
+ *
+ * All failures throw ProviderError (src/network/errors.js) with a `code`
+ * and `retryable` hint. Providers map their native errors at the boundary
+ * so no provider-specific error type ever escapes this package.

+/**
+ * WireGuard hub firewall for the DashCaddy Private Network (DC-151,

+ *
+ * Two halves:
+ *
+ * 1. compileRuleset() — a PURE compiler (no I/O, fully deterministic):
+ *    access map + people + peer addresses + resources → the complete
+ *    nftables ruleset text for table `inet dcnet`.
+ *
+ *    Baseline model (corrected per judge-gate review of §8.1):
+ *      - The WireGuard UDP listen port carries HANDSHAKE traffic that
+ *        arrives on the EXTERNAL interface, never on dcnet0. The accept
+ *        rule is scoped to `externalInterface` when given, otherwise
+ *        emitted interface-unscoped with an explanatory comment.
+ *      - dcnet0 LOCAL input (input chain, iifname "dcnet0"): established/
+ *        related, ICMP from 10.53.0.0/16, admin ports (API 3001 / SSH 22)
+ *        ONLY from the admin set, hub-local resource ports to 10.53.0.1,
+ *        then drop other new inbound to the hub IP.
+ *      - PEER traffic (forward chain): per-resource nft sets
+ *        (`net_dc_res_<name>`) gate saddr→resource ip:dport for resources
+ *        living at peer /32s; default-deny tails drop ALL other iifname
+ *        "dcnet0" (peer egress without a grant) and oifname "dcnet0"
+ *        (peer-to-peer + new hub→peer) traffic.
+ *
+ *    Default-deny everywhere on dcnet0-derived traffic; blocked people's
+ *    IPs appear in NO set (resource sets nor the admin set).
+ *
+ * 2. createWgFirewallApplier() — transactional apply with injectable
+ *    { execFileImpl, fsImpl }: write to a UNIQUE temp file, `nft -c -f`
+ *    (check), write the rollback file (previous ruleset) BEFORE applying,
+ *    `nft -f` (apply), verify via `nft list table inet dcnet`, roll back
+ *    on verify mismatch. A check failure deletes the temp file and throws
+ *    FirewallCheckError with NOTHING applied; an apply failure leaves the
+ *    old rules and the rollback file untouched and throws with
+ *    { applied: false }.
+ *
+ * 3. assertAdminIsolation() — static guard (tests + DC-148-style callers):
+ *    every admin-port rule must be scoped to the admin set only.

+/**
+ * Private Network setup wizard orchestrator — DC-152
+ * (specs/PRIVATE-NETWORK-SPEC.md §9, NORMATIVE step order:
+ *  mode → domain → connect → dns → ca → admin → complete).
+ *
+ * Every dependency is injectable so tests stay hermetic:
+ *   registry        — src/network/registry.js (setActiveProvider/getActiveProvider)
+ *   providers       — { tailscale, wireguard } provider instances used for
+ *                     credential/dependency validation and syncs
+ *   peopleStore     — src/security/network-people-store.js instance
+ *   accessStore     — network-access-store instance (reserved; not yet read)
+ *   technitium      — OPTIONAL: { checkSetup(), configureSplitDns(...) }
+ *   caSetup         — OPTIONAL: { setupNamedRootCA({ commonName, privateTld }) }
+ *   credentialStore — OPTIONAL: credential-manager-shaped { store, retrieve, delete }
+ *   logger, stateStore / stateFile
+ *
+ * Wizard state persists at data/network-wizard-state.json:
+ *   { step, mode, privateTld, providerConnected, dnsConfigured, caConfigured,
+ *     adminCreated, startedAt, completedAt }
+ *
+ * Credential reuse (NOT duplicated): Tailscale credentials go through the SAME
+ * credential-manager keys the existing settings UI uses —
+ *   'tailscale.coord.apiToken'     (src/context/index.js tailscaleCoord.setApiToken)
+ *   'tailscale.oauth.client_id' / 'tailscale.oauth.client_secret'
+ *                                   (routes/tailscale.js oauth-config)
+ * The prod tailscale provider reads the token from credentialManager on every
+ * call, so store-then-validate ordering works without restarting anything.

+ * Network access store — DC-145.

+ *   {
+ *     grants: [{ principal: {type:'person'|'group', id}, resource, allowed }],

+ *     person grant (true or false) always wins over any group grant.
+ *   - A group's effective access is just its own grants.
+ *
+ * The store knows only principal IDs — it never reads people.json. Group
+ * membership is supplied by the caller (from the people store) as an array
+ * of group IDs on the principal.
+ *
+ * Change events: subscribe(fn) registers a listener fired after every
+ * successful mutation with the new map. The ACL compiler (DC-148) uses this
+ * to recompile provider rules. Listeners run after the atomic write has
+ * completed, are isolated (one listener throwing never breaks the mutation
+ * or other listeners), and unsubscribe on return value.
+ *

+
+## 1. What we're building
+
+DashCaddy turns a tailnet (or a self-hosted WireGuard hub) into a **managed private
+network**: people, devices, per-app access, private DNS names, and a personal
+certificate authority — all from one panel.
+
+Two network modes, one product:
+
+| | Tailscale mode (v1 default) | WireGuard mode (self-hosted) |
+|---|---|---|
+| Data plane | Tailscale (direct, NAT traversal) | WireGuard hub run by DashCaddy on the host |
+| Control plane | api.tailscale.com (OAuth client preferred; API key fallback) | DashCaddy itself (host wg-quick + key store) |
+| Invites | Tailscale user-invites API, link-first (no email required) | DashCaddy invite link + QR config |
+| Block/remove | API device expire/delete + ACL deny | Remove peer from hub + firewall rule |
+| Unblock | Re-allow at ACL level; expired device keys must re-authenticate (see §5) | Re-add peer from stored record (immediate) |
+| Rules | Tailnet policy ACLs compiled by DashCaddy | Hub firewall (nftables set-based) compiled by DashCaddy |
+| Outside dependency | Yes | None |
+
+**Everything above the provider is shared**: people, groups, resources, the access
+map, forward_auth enforcement, Technitium names, the CA, the UI. 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. Provider abstraction (DC-140)
+
+`src/network/` package:
+
+```
+src/network/provider.js        — NetworkProvider interface (documented contract)
+src/network/registry.js        — active provider resolution + capability flags
+src/network/errors.js          — ProviderError { code, retryable }
+src/network/providers/tailscale.js
+src/network/providers/wireguard.js
+```
+
+Contract (all async, all return plain JSON, all validated):
+
+| Method | Tailscale impl | WireGuard impl |
+|---|---|---|
+| `id()`, `capabilities()` | `'tailscale'` | `'wireguard'` |
+| `getStatus()` | tailscale status --json (cached, existing manager) | wg show dump + iface up/down |
+| `listDevices()` | API + local status merge | peer store read |
+| `listPeople()` | API users → people projection | people.json (self-owned) |
+| `createInvite({role, email?})` | POST user-invites (email optional → returns inviteUrl) | mint one-time invite token in store |
+| `revokeInvite(id)` | DELETE user-invite | delete token |
+| `blockPerson(userId)` | expire all device keys + ACL deny | drop peer + firewall deny set |
+| `unblockPerson(userId)` | re-allow at ACL level; expired device keys stay expired (re-auth required, §5) | re-add stored peer (immediate) |
+| `removePerson(userId)` | DELETE devices, revoke invites | remove peer + person record |
+| `revokeDevice(deviceId)` | expire/delete device key | remove single peer |
+| `syncAccess(map, resources)` | compile ACLs → dry-run → push (hash-guarded) | compile nftables → apply → verify |
+| `whois(ip)` | local tailscale whois | peer table lookup |
+| `configureDns({zone, server})` | split-DNS API | not supported (Technitium direct) |
+
+Capabilities: `{ invites, splitDnsApi, perPeerFirewall, selfHosted }`. 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: network-layer deny (ACL / firewall) + expire Tailscale device keys + kill
+  DashCaddy sessions + mark person blocked. **Unblock honestly:** the deny, the
+  status, and the session policy reverse — but expired Tailscale device keys are
+  NOT un-expired; those devices must re-authenticate with Tailscale on next
+  connect. The UI says "blocked devices will need to sign in again" rather than
+  pretending instant reversal. WireGuard peers restore immediately on re-add
+  (peer config is re-generated server-side from the stored pubkey).
+- 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:<private-tld>). 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.<tld>: 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)
+
+### 8.1 Addressing and routing (exact prefixes)
+
+- Hub interface `dcnet0`: 10.53.0.1/16, listen port chosen at setup (default 51820,
+  UDP). Endpoint = host's reachable address (setup captures it; wizard warns if
+  it's behind NAT without a forwarded port).
+- Client address pool: 10.53.0.0/16, one /32 per device (10.53.x.y/32 assigned
+  on device add, stable, stored in people.json devices[]).
+- **AllowedIPs = 10.53.0.0/16 only** (a CIDR, never a DNS zone). Split tunnel:
+  client's other traffic is untouched. Resource names resolve via Technitium
+  (8.3) to IPs inside 10.53.0.0/16, which routes through the tunnel.
+- Hub forwarding: `net.ipv4.ip_forward=1` is required for hub-and-spoke
+  peer→peer traffic; peer→hub-resource traffic is local. No NAT/masquerade on
+  dcnet0 — all resource access is to hub-local services on 10.53.0.1 or to
+  other peers' /32s, so addresses stay routable and firewall rules match peers.
+- Firewall baseline — three distinct zones, never conflated:
+  (a) **External input**: the WireGuard UDP listen port arrives on the EXTERNAL
+  interface (e.g. eth0), not dcnet0 — its accept rule is scoped to the external
+  interface name (captured at setup).
+  (b) **dcnet0 local input** (iifname dcnet0): ICMP from 10.53.0.0/16, admin
+  ports (API/SSH on 10.53.0.1) from admin peers only, per-resource ports to
+  10.53.0.1; drop other new inbound to 10.53.0.1.
+  (c) **dcnet0 forwarding** (ip_forward=1): peer→resource gated by per-resource
+  sets; peer→peer default DROP (both iifname and oifname dcnet0 tails) unless a
+  grant implies it.
+
+### 8.2 Key lifecycle (no server-side private-key storage)
+
+- **Client keypairs are generated in the invitee's browser** using WebCrypto
+  **X25519** — WireGuard requires Curve25519 key material; there is NO fallback
+  algorithm (a browser lacking X25519 support gets an explicit "browser not
+  supported" error, not a degraded key). Serialization (browser-export
+  reality): `exportKey('raw', publicKey)` yields the raw 32-byte public key →
+  base64. `exportKey('pkcs8', privateKey)` yields a PKCS#8 wrapper — the page
+  strips the fixed 16-byte PKCS#8 X25519 prefix (`302e020100300506032b656e0422
+  0420`) to extract the raw 32-byte private key → base64 (`wg genkey`-format;
+  the extraction is pure byte-slicing of a fixed-prefix wrapper, verified by
+  length/constant-prefix assertions before use). The server receives the base64
+  public key (44 chars) and validates length/charset before use.
+- The redemption page posts ONLY the public key to the server; the server
+  registers it as a WireGuard peer (10.53.x.y/32) and returns the client
+  config (Address, DNS, PublicKey of hub, AllowedIPs = 10.53.0.0/16).
+- The private key NEVER transits or rests on the server: it lives in the
+  browser page for the session, rendered into the config + QR client-side.
+- Server stores: peer public keys, assigned /32s, names — nothing else.
+- Revocation = remove peer (pubkey) from the hub + firewall-set update; the
+  client's private key becomes useless without hub acceptance.
+
+### 8.3 DNS
+
+- Technitium serves the private zone on the hub IP (10.53.0.1). Client config
+  DNS = 10.53.0.1. Per-resource/per-device records resolve to 10.53.x.y /32s
+  (per DC-146). In Tailscale mode, the same records hold tailnet IPs instead.
+
+### 8.4 Hub management
+
+- `wg-quick` interface `dcnet0` managed by DashCaddy (systemd unit
+  `dcnet-hub.service` if absent), keygen for the HUB keypair on the host
+  (hub key is host-local and backed up with it).
+
+### 8.5 Invites
+
+- Invite redemption: one-time token (7-day TTL, single-use) → redemption page
+  (browser keygen per 8.2) → config + QR rendered client-side, page
+  auto-expires after redemption.
+
+- Firewall: nftables matrix (section 4). 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.
+
+WireGuard mode dependency note: "no third party" still depends on host
+networking — a reachable UDP endpoint, wireguard-tools, nftables, and Technitium
+on the DashCaddy host.
+
+## 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).
