-# 0.7.0-beta.4 (May 31, 2026)
-
-> This is a beta release. Please report any issues you encounter.
-
-- **Headplane now requires Headscale 0.27.0 or newer.** Support for 0.26.x has been dropped. If `/version` returns 404 (the endpoint was added in 0.27.0), Headplane logs an error and keeps retrying so an in-place Headscale upgrade is picked up without a restart.
-- **Replaced the OpenAPI hash detection with `/version`.** Capabilities are now derived from the version reported by `/version` instead of fingerprinting the OpenAPI schema. This dramatically simplifies version detection and works with every supported release out of the box.
-- **Made Headscale boot resilient.** Headplane now boots even when Headscale is unreachable; capabilities default permissively and a background retry settles them once Headscale responds. No more cold-start ordering problems with docker-compose.
-- **Added optional in-process TLS termination.** Setting `server.tls_cert_path` and `server.tls_key_path` makes Headplane serve HTTPS/1.1 on `server.port` directly — no reverse proxy required. `server.cookie_secure` is auto-forced to `true` (with a warning) whenever TLS is enabled, since browsers refuse `Secure`-less cookies over HTTPS. HTTP/2 and HTTP/3 are intentionally not supported in-process; terminate those at a reverse proxy if you need them (closes [#403](https://github.com/tale/headplane/issues/403)).
-- **Made the bundled Docker healthcheck zero-config across HTTP and HTTPS.** Headplane writes its loopback URL (scheme, port, and basename included) to `/tmp/headplane-listen` on startup, and `hp_healthcheck` reads that file and probes the URL verbatim. Enabling TLS or changing `server.port` no longer requires any healthcheck-specific configuration. Native installs are unaffected — the listen file is only written when `HEADPLANE_LISTEN_FILE` is set, which the Dockerfile does automatically.
-- Added Rename and Delete actions for unlinked Headscale users on the Users page so admins can manage Headscale users that have no Headplane account (closes [#525](https://github.com/tale/headplane/issues/525)).
-- Documented [Custom Certificate Authorities](/configuration/tls#custom-certificate-authorities) for trusting private or self-signed CAs across every outbound TLS connection (OIDC, Headscale, Docker, etc.) via Node's `NODE_EXTRA_CA_CERTS`. This replaces the previous workaround of rebuilding the Docker image to extend the system trust store (closes [#313](https://github.com/tale/headplane/issues/313)).
-- Fixed user-management actions (link, change role, transfer ownership) using the wrong ID type for unlinked Headplane users. Form fields are now explicitly `headplane_user_id` vs. `headscale_user_id`, and the auth layer no longer round-trips through Headscale to recover the OIDC subject.
-- Fixed the "Register Machine Key" dialog passing the Headscale numeric user id instead of the username. Headscale's `RegisterNodeRequest.user` proto field is a `string` looked up via `GetUserByName` (no numeric fallback), so registration was failing whenever the selected owner's display name differed from their numeric id (closes [#532](https://github.com/tale/headplane/issues/532)).
-- Fixed pre-auth key expiration on Headscale 0.27.x. The pre-0.28 expire endpoint takes a `uint64 user` field which the API layer reads from `key.user?.id`, but the caller was wrapping the id as `{ name: user }`, causing the request to send an empty user field. Headplane now correctly passes the numeric Headscale user id.
-- Fixed dialog panels growing beyond the viewport; dialog content is now constrained and scrollable (via [#556](https://github.com/tale/headplane/pull/556)).
-- Fixed focus rings on inputs and buttons inside dialogs being clipped by the scrollable content container.
-- Fixed tooltips on the last row of the machines table being clipped by the viewport; tooltips now anchor above the trigger with collision padding (closes [#508](https://github.com/tale/headplane/issues/508)).
-- Corrected the Docker healthcheck example in the docs to use the required `CMD` prefix so reverse proxies don't see the container as unhealthy (closes [#535](https://github.com/tale/headplane/issues/535)).

+# Headplane codebase findings
+
+Date: 2026-05-16
+
+Scope: server-side TypeScript, React Router route modules, client components, live-data/data-fetching paths, auth/session/RBAC, Headscale config/API integration, Go agent/WebSSH code, runtime/build/CI, and docs. This is an architecture and pattern review, not a completed security audit.
+
+## Executive summary
+
+Headplane's biggest codebase risks are not isolated style issues; they cluster around ownership boundaries:
+
+- **Auth/session boundary:** API-key sessions put the raw Headscale API key in the auth cookie, and self-service account linking can claim arbitrary unclaimed Headscale users.
+- **Live-data boundary:** the current live path polls globally, caches globally, and tells React Router to re-run whole active route loaders on any resource change.
+- **Lifecycle boundary:** process-lifetime services have `setInterval`, child processes, SSE streams, Undici agents, and WASM/tsnet state, but there is no coordinated shutdown/disposal model.
+- **Mutation boundary:** config-file edits and several admin/user mutations rely on UI constraints, mutable process state, non-transactional writes, or inconsistent server-side validation.
+- **Framework/tooling boundary:** React Router loaders/actions currently carry a lot of app state orchestration. Fate could be a good fit for live `nodes`/`users` data, but it will not fix auth, authorization, config mutation, WebSSH, or agent lifecycle issues by itself.
+
+## Highest-priority findings
+
+### 1. OIDC self-linking can claim arbitrary unclaimed Headscale users
+
+**Severity:** Critical  
+**Area:** AuthZ / account linking
+
+**Evidence:**
+
+- `app/routes/home.tsx:84-97` accepts a posted `headscale_user_id` and calls `context.auth.linkHeadscaleUser(principal.user.id, headscaleUserId)`.
+- `app/server/web/auth.ts:225-237` grants machine ownership based on `principal.user.headscaleUserId === node.user?.id`.
+- `app/routes/machines/machine-actions.ts:57-68` authorizes machine mutations through `canManageNode`.
+
+**Why it matters:** a logged-in OIDC user can forge the form POST and link themselves to any unclaimed Headscale user ID. Once linked, they can manage that user's machines through the machine action authorization path.
+
+**Suggested direction:** recompute allowed self-link targets server-side inside the action and reject anything not in that set. Prefer auto-linking only by verified OIDC subject/email match, and reserve arbitrary linking for admins.
+
+### 2. API-key sessions put the raw Headscale API key in a signed cookie
+
+**Severity:** Critical  
+**Area:** Auth/session security
+
+**Evidence:**
+
+- `app/server/web/auth.ts:96-105` manually base64url-encodes JSON and signs it with HMAC.
+- `app/server/web/auth.ts:269-283` serializes `{ sid, api_key }` for API-key sessions.
+- `app/server/web/auth.ts:144-173` resolves API-key principals from `payload.api_key`; the DB `api_key_hash` is not used to retrieve a server-side secret.
+- `app/utils/oidc-state.ts:13-19` explicitly sets `httpOnly`, while the main auth cookie options are not explicit in `app/server/context.ts:49-54` / `app/server/web/auth.ts:96-105`.
+- `docs/install/index.md` describes `server.cookie_secret` as encrypting cookies, but the implementation signs rather than encrypts.
+
+**Why it matters:** cookie compromise becomes direct Headscale API compromise, not just Headplane session compromise. HMAC protects integrity, not confidentiality. The auth cookie should be an opaque session handle, not a transport for upstream credentials.
+
+**Suggested direction:** store only `sid` in the cookie; keep the API key encrypted or server-side in the DB/secret store; verify `api_key_hash` if retaining API-key sessions; explicitly set `httpOnly`, `sameSite`, `secure`, `path`, and consider key rotation/versioning. Use timing-safe HMAC comparison if manual signatures remain.
+
+## Live data and data-fetching findings
+
+### 3. SSE events trigger whole-route revalidation instead of resource-scoped updates
+
+**Severity:** High  
+**Area:** Client data fetching / live data
+
+**Evidence:**
+
+- `app/utils/live-data.tsx:35-39` calls `revalidator.revalidate()`.
+- `app/utils/live-data.tsx:63-82` treats every `changed` event as a global route revalidation.
+- `app/routes/util/live.ts:34-37` sends only `{ resource, version }`, not field/object-level deltas or subscribed views.
+
+**Why it matters:** any node/user change can re-run every active loader for the current route tree. Pages such as machines/users load multiple resources and agent metadata, so frequent Headscale changes can become over-fetching and UI churn.
+
+**Suggested direction:** short term, include enough resource metadata to revalidate only affected routes or debounce/coalesce revalidation. Long term, move live data to normalized object/list subscriptions instead of request/route invalidation.
+
+### 4. Live-data pause state is global, boolean, and can stick disabled
+
+**Severity:** High  
+**Area:** Client state / live data
+
+**Evidence:**
+
+- `app/root.tsx:41-66` mounts `LiveDataProvider` above all routes.
+- `app/routes/auth/login/page.tsx:59-66` calls `pause()` with no dependency array and no cleanup/resume.
+- `app/components/dialog.tsx:21-27` uses the same single boolean pause model for dialogs.
+- `app/utils/live-data.tsx:136-141` exposes imperative `pause()` / `resume()` with no ownership token.
+
+**Why it matters:** visiting `/login` can leave live updates disabled after navigating into the app. Multiple pause consumers can also fight: closing one dialog can resume live updates while another still expects them paused.
+
+**Suggested direction:** add immediate cleanup in login (`pause(); return resume`) and a dependency array. Replace the boolean with a refcount/token model so each consumer releases only its own pause.
+
+### 5. `hsLive` is process-global but stores one mutable API client
+
+**Severity:** High  
+**Area:** Server live data / cache scoping
+
+**Evidence:**
+
+- `app/server/context.ts:86-101` creates one `hsLive` for the entire process.
+- `app/server/headscale/live-store.ts:69` keeps `storedApiClient` in shared closure state.
+- `app/server/headscale/live-store.ts:113-120` polling uses that shared client.
+- `app/server/headscale/live-store.ts:143` and `app/server/headscale/live-store.ts:158` overwrite it from each caller.
+
+**Why it matters:** the last request/action to touch `hsLive` controls which API key future background polls use. A bad/expired user-supplied API-key session can poison live refresh for everyone until another request resets it. Snapshots are also not principal/session scoped.
+
+**Suggested direction:** poll with one stable server credential only, or scope cache/polling by principal/session. If adopting Fate, make this one of the first seams to replace.
+
+### 6. Live store polling is coarse and lifecycle-unmanaged
+
+**Severity:** Medium  
+**Area:** Server lifecycle / live data
+
+**Evidence:**
+
+- `app/server/headscale/live-store.ts:38-45` polls nodes every 5s and users every 15s.
+- `app/server/headscale/live-store.ts:82-104` compares `JSON.stringify(data)` for the whole resource.
+- `app/server/headscale/live-store.ts:113-123` starts intervals lazily but never stops them unless `dispose()` is called.
+- `app/server/context.ts:94` creates the store, but no app shutdown path calls `hsLive.dispose()`.
+
+**Why it matters:** whole-resource JSON comparison is order-sensitive and grows with tailnet size. The polling intervals continue for process lifetime and can leak during dev HMR or repeated context creation.
+
+**Suggested direction:** introduce app-level lifecycle management and subscription-aware polling, or replace with event/object-scoped live subscriptions.
+
+### 7. Loader data is mirrored into local state and can overwrite edits during revalidation
+
+**Severity:** Medium  
+**Area:** Client state / React patterns
+
+**Evidence:**
+
+- `app/routes/acls/overview.tsx:30-41` mirrors `policy` into `codePolicy` and updates it when loader data changes.
+- `app/routes/dns/components/manage-domains.tsx:25-31` mirrors `searchDomains` into local state.
+
+**Why it matters:** global SSE revalidation can replace local edit state. The ACL editor is especially risky because an unsaved policy can be overwritten by background loader refresh.
+
+**Suggested direction:** separate “initial server value” from “dirty draft” state; never overwrite dirty drafts on background revalidation without prompting.
+
+### 8. Fetcher/dialog orchestration is imperative and duplicated
+
+**Severity:** Medium  
+**Area:** Client forms / mutations
+
+**Evidence:**
+
+- `app/routes/machines/dialogs/tags.tsx:34-43` uses `submittingRef` + effects to close/unlock.
+- `app/routes/settings/auth-keys/dialogs/add-auth-key.tsx:56-71` uses similar orchestration and directly assigns `fetcher.data = undefined`.
+- `app/routes/machines/dialogs/routes.tsx:49-63` submits on switch changes without optimistic/error state.
+
+**Why it matters:** each dialog reimplements mutation lifecycle handling. Direct mutation of `fetcher.data` fights router-owned state and can hide stale or failed submissions.
+
+**Suggested direction:** centralize fetcher mutation state handling, or move to an action/mutation primitive with explicit pending/error/success states and optimistic updates.
+
+## Auth, authorization, and route handling findings
+
+### 9. Agent settings route/action lacks capability checks
+
+**Severity:** High  
+**Area:** Authorization
+
+**Evidence:**
+
+- `app/routes/settings/agent.tsx:13-27` only authenticates.
+- `app/routes/settings/agent.tsx:29-39` only authenticates before triggering sync.
+
+**Why it matters:** any authenticated user can view agent status and trigger sync work if they know the URL, regardless of settings/admin capability.
+
+**Suggested direction:** gate read and sync separately, probably using `read_feature`/`write_feature` or a dedicated agent capability.
+
+### 10. App layout catches all loader errors and destroys sessions
+
+**Severity:** High  
+**Area:** Error handling / auth UX
+
+**Evidence:**
+
+- `app/layout/app.tsx:32-103` wraps the whole loader in `try/catch` and redirects to `/login` with `destroySession()` for any error.
+- `app/layout/app.tsx:50-67` handles one expected expired-API-key case, but the outer catch covers unrelated failures too.
+
+**Why it matters:** network errors, programming errors, and transient Headscale failures can become silent logouts. It also hides diagnostics from route error boundaries.
+
+**Suggested direction:** catch only expected auth/session errors; let operational/programming errors hit the error boundary or a health banner.
+
+### 11. RBAC is inconsistent across routes/actions
+
+**Severity:** Medium/High  
+**Area:** Authorization
+
+**Evidence:**
+
+- `app/routes/machines/machine-actions.ts:64-68` performs resource-specific checks via `canManageNode`.
+- `app/routes/users/user-actions.ts:10-17` checks only broad `write_users` before operations.
+- `app/routes/home.tsx:84-97` lets OIDC users link Headscale identities without revalidating target ownership.
+- `app/routes/settings/auth-keys/actions.ts:23-35` has more careful self-service ownership checks, showing the pattern exists but is not universal.
+
+**Why it matters:** permissions are enforced route-by-route with no single policy layer, so new actions can accidentally rely on UI hiding. The self-linking issue is one concrete outcome.
+
+**Suggested direction:** create server-side action guards for common ownership/role decisions and require every mutation to call one.
+
+### 12. Runtime role input is not validated and ownership updates are non-transactional
+
+**Severity:** Medium  
+**Area:** Auth/RBAC data integrity
+
+**Evidence:**
+
+- `app/routes/users/user-actions.ts:82-104` casts `newRole as Role` from form data.
+- `app/server/web/auth.ts:467-484` upserts that role into the DB.
+- `app/server/web/auth.ts:430-464` transfers ownership with two separate updates.
+- `app/server/web/auth.ts:324-342` makes the first user owner with a count-after-insert flow.
+
+**Why it matters:** forged role values can reach storage, and failures/races in ownership transfer or first-login owner selection can produce invalid owner state.
+
+**Suggested direction:** validate `newRole` against `Roles` at the route boundary, use transactions for ownership transfer, and make first-owner assignment atomic.
+
+### 13. Login page has live-data and URL cleanup bugs
+
+**Severity:** Medium  
+**Area:** Client route behavior
+
+**Evidence:**
+
+- `app/routes/auth/login/page.tsx:59-66` pauses live data on every render and never resumes.
+- `app/routes/auth/login/page.tsx:68-84` uses `window.history.replaceState` manually.
+- `app/routes/auth/login/page.tsx:78-80` builds `newUrl` with `` `{${window.location.pathname}?...` ``, leaving a literal `{` in the URL.
+
+**Why it matters:** this can disable live updates and corrupt/uglify login URLs. Manual history mutation bypasses router state.
+
+**Suggested direction:** use a loader redirect or router navigation where possible; otherwise fix the string and make the effect one-shot with cleanup.
+
+## Headscale API and config mutation findings
+
+### 14. Headscale API errors are collapsed into `502 Bad Gateway`
+
+**Severity:** Medium/High  
+**Area:** API wrapper / error handling
+
+**Evidence:**
+
+- `app/server/headscale/api/index.ts:139-145` converts network errors to React Router `data(..., 502)`.
+- `app/server/headscale/api/index.ts:183-203` converts every Headscale `>=400` response to outer status 502 while preserving the real status only inside the body.
+- Many callers inspect raw strings/statuses manually, e.g. `app/routes/auth/login/action.ts:78-93` and `app/routes/acls/acl-action.ts:39-107`.
+
+**Why it matters:** UI and route logic must understand wrapper internals. HTTP semantics are obscured, and handling becomes string-fragile.
+
+**Suggested direction:** preserve upstream status classes where safe, expose typed domain errors, and make expected Headscale quirks explicit in one adapter layer.
+
+### 15. OpenAPI polling interval has no disposal and returned interface exposes stale values
+
+**Severity:** Medium  
+**Area:** Server lifecycle / API versioning
+
+**Evidence:**
+
+- `app/server/headscale/api/index.ts:241-250` starts a `setInterval` inside `createHeadscaleInterface`.
+- `app/server/headscale/api/index.ts:252-272` returns `openapiHashes` and `apiVersion` as values captured at return time, while `clientHelpers.isAtleast` reads the mutable closure.
+- No `dispose()` exists on the interface.
+
+**Why it matters:** lifecycle leaks in dev/reload scenarios, and consumers reading `context.hsApi.apiVersion` can see stale data while helpers see updated data.
+
+**Suggested direction:** add lifecycle, expose getters for mutable version state, or only detect once at startup.
+
+### 16. Config patching is not safely serialized
+
+**Severity:** Medium/High  
+**Area:** Config mutation / concurrency
+
+**Evidence:**
+
+- `app/server/headscale/config-loader.ts:63-127` mutates the YAML document before acquiring `writeLock`.
+- `app/server/headscale/config-loader.ts:120-127` sets `writeLock = true` without `try/finally`; a failed write can leave the lock stuck.
+- `app/server/headscale/config-dns.ts` has a similar write-lock pattern (see `writeLock` usage).
+
+**Why it matters:** concurrent admin actions can interleave mutations, lose updates, or deadlock future writes after an exception.
+
+**Suggested direction:** replace the boolean lock/spin loop with a promise queue or mutex; acquire before document mutation; release in `finally`; write atomically via temp file + rename.
+
+### 17. DNS/config actions mutate shared config arrays and lack input validation
+
+**Severity:** Medium  
+**Area:** Config mutation / validation
+
+**Evidence:**
+
+- `app/routes/dns/dns-actions.ts:103-118` pushes nameservers into arrays read from `context.hs.c`.
+- `app/routes/dns/dns-actions.ts:147-164` pushes search domains into arrays read from `context.hs.c`.
+- `app/routes/dns/dns-actions.ts:189-209` writes DNS record type/value from form data with minimal validation.
+
+**Why it matters:** in-memory config can be mutated before persistence succeeds, and invalid values can be written directly to Headscale config.
+
+**Suggested direction:** clone before modification, validate domain/IP/record types server-side, and return actionable typed errors.
+
+### 18. Restrictions config actions fire integration restarts without awaiting them
+
+**Severity:** Medium  
+**Area:** Config mutation / operational consistency
+
+**Evidence:**
+
+- `app/routes/settings/restrictions/actions.ts:51`, `:79`, `:100`, `:129`, `:150`, `:179` call `context.integration?.onConfigChange(api)` without `await`.
+- `app/routes/dns/dns-actions.ts` generally awaits the same hook.
+
+**Why it matters:** the response can report success while restart/reload fails in the background, and unhandled rejections can be lost.
+
+**Suggested direction:** await the hook consistently or queue/retry restarts through an explicit background job with surfaced status.
+
+## Server lifecycle and runtime findings
+
+### 19. Process-lifetime services have no composition-root `stop()`
+
+**Severity:** High  
+**Area:** Server lifecycle
+
+**Evidence:**
+
+- `app/server/context.ts:21-101` constructs DB, Headscale API, live store, auth service, OIDC, optional agent manager, and integration.
+- `app/server/app.ts:38-40` starts auth pruning.
+- `app/server/hp-agent.ts:319-359` starts an interval and child process with `dispose()`.
+- `app/server/headscale/live-store.ts:182-191` has `dispose()`.
+- `runtime/http.ts:192-200` handles SIGINT/SIGTERM by closing the HTTP server and exiting, but has no app context cleanup.
+- `runtime/vite-plugin.ts:44-50` uses `ssrLoadModule` in dev; HMR can recreate modules/services without calling old disposers.
+
+**Why it matters:** intervals, child processes, SSE listeners, and Undici agents can leak in dev and are force-killed in production instead of being drained.
+
+**Suggested direction:** return an app runtime with `stop()` from the composition root; call `auth.stop()`, `hsLive.dispose()`, `agents.dispose()`, `hsApi.undiciAgent.close()`, and integration cleanup from production shutdown and Vite HMR dispose hooks.
+
+### 20. Architecture docs describe patterns the code no longer fully follows
+
+**Severity:** Medium  
+**Area:** Documentation / maintainability
+
+**Evidence:**
+
+- `docs/development/architecture.md:15-20` says all services are closure factories, no classes/globals.
+- `app/server/headscale/config-loader.ts:21-213` uses a mutable class for Headscale config.
+- `docs/development/architecture.md:162-218` describes `server/index.ts`, `AppRuntime`, and `context.runtime`, while current code uses `app/server/app.ts`, `createAppContext`, and direct `context.<service>`.
+
+**Why it matters:** docs are important to this project. Stale architecture guidance makes future changes less consistent and harder for agents/contributors to follow.
+
+**Suggested direction:** update the architecture docs to the current composition root and explicitly document exceptions such as config-file wrappers.
+
+## Go agent and WebSSH findings
+
+### 21. WebSSH WASM lacks a top-level disposal model and leaks JS functions
+
+**Severity:** High  
+**Area:** WebSSH lifecycle / browser resources
+
+**Evidence:**
+
+- `app/routes/ssh/page.tsx:156-188` creates the WASM/IPN instance and cleanup only sets `cancelled = true`.
+- `app/routes/ssh/wasm.client.ts:27-29` exposes `openTunnel` only; no `dispose()`.
+- `cmd/hp_ssh/hp_ssh.go:16-80` creates JS functions but never releases them with `js.Func.Release()`.
+- `internal/hp_ipn/ipnserver.go:107-133` starts backend/server work but exposes no shutdown API.
+
+**Why it matters:** repeated SSH sessions can leave in-browser tsnet/backend resources and JS function handles alive until tab refresh.
+
+**Suggested direction:** add top-level `dispose()` to the JS API, release Go `js.Func` handles, cancel contexts, close sessions/backend/server, and call dispose from React cleanup.
+
+### 22. WebSSH disables SSH host key verification
+
+**Severity:** Medium/High  
+**Area:** Security / WebSSH
+
+**Evidence:**
+
+- `internal/hp_ipn/ssh.go:59-63` returns `nil` from `HostKeyCallback`.
+
+**Why it matters:** this accepts any host key and allows MITM within the network path. Tailscale identity reduces exposure, but SSH host identity is still bypassed.
+
+**Suggested direction:** document the tradeoff clearly at minimum. Prefer known_hosts-style pinning, Tailscale SSH identity integration, or an explicit trust-on-first-use flow.
+
+### 23. Go agent can panic on peers without Tailscale IPs
+
+**Severity:** Medium  
+**Area:** Go agent robustness
+
+**Evidence:**
+
+- `internal/tsnet/peers.go:61` indexes `peer.TailscaleIPs[0]`.
+- `internal/tsnet/peers.go:119` also indexes `peer.TailscaleIPs[0]` before checking `len(ip) == 0`.
+
+**Why it matters:** transient or malformed peer state can crash host-info collection.
+
+**Suggested direction:** check `len(peer.TailscaleIPs) > 0` before indexing in both paths.
+
+### 24. Go agent preflight uses `http.Get` without timeout and does not close response bodies
+
+**Severity:** Medium  
+**Area:** Go agent robustness
+
+**Evidence:**
+
+- `internal/config/preflight.go:40-56` calls `http.Get(testURL)` directly.
+- `internal/config/preflight.go:47-54` never closes `resp.Body`.
+
+**Why it matters:** startup can hang indefinitely on network issues, and response bodies leak.
+
+**Suggested direction:** use `http.Client{Timeout: ...}` and `defer resp.Body.Close()`.
+
+### 25. Go library-like code exits the process and logging is hand-rolled
+
+**Severity:** Medium  
+**Area:** Go maintainability
+
+**Evidence:**
+
+- `internal/tsnet/server.go:22-72` uses `log.Fatal` inside `NewAgent`/`Connect` rather than returning errors.
+- `internal/util/logger.go:25-29` defines `encoder` and `pool`, but `internal/util/logger.go:59-66` only writes plain stderr lines and exits on fatal.
+
+**Why it matters:** callers cannot recover or return structured errors, and the logger has unused complexity while still lacking structured output.
+
+**Suggested direction:** return errors from `NewAgent`/`Connect`, let `cmd/hp_agent` decide process exit, and simplify or replace the logger.
+
+## Build, CI, and tooling findings
+
+### 26. CI does not explicitly run typecheck or lint
+
+**Severity:** Medium  
+**Area:** Tooling / quality gates
+
+**Evidence:**
+
+- `package.json` has `typecheck`, `lint`, and `format` scripts.
+- `.github/workflows/build.yaml:32-37` runs `./build.sh --skip-pnpm-prune`, unit tests, and integration tests.
+- `build.sh:157-173` runs `pnpm run build`, not `pnpm run typecheck` or `pnpm run lint`.
+
+**Why it matters:** Vite/React Router builds transpile TypeScript but are not a substitute for `tsgo` typechecking. Lint-only issues can land despite local scripts existing.
+
+**Suggested direction:** add `pnpm run typecheck` and `pnpm run lint` to CI. Consider `pnpm run format --check` if supported by oxfmt.
+
+### 27. Build script leaves temporary `vendor/` behind if WASM build fails
+
+**Severity:** Low/Medium  
+**Area:** Build hygiene
+
+**Evidence:**
+
+- `build.sh:143-154` runs `go mod vendor`, applies a patch, builds, then removes `vendor` only after success.
+
+**Why it matters:** failed local builds can leave a large generated directory in the worktree, which is easy to accidentally inspect or commit around.
+
+**Suggested direction:** add a trap around the vendoring step to remove `vendor` on failure.
+
+## Fate/SPA/Vite+ migration assessment
+
+### Updated direction: SPA first, not Void first
+
+After comparing the shape of Headplane with Void's current platform/runtime direction, the better target is **not** a Void app. Headplane is a self-hosted local control-plane UI that needs a predictable Node process, local filesystem/config access, SQLite, child process/agent management, long-lived SSE, and a packaging story that can eventually compile into a Node static SEA.
+
+The preferred target is now a one-way SPA cutover:
+
+```text
+Hono Node server + Vite SPA + TanStack Router + raw Fate
+```
+
+The important architectural choice is that **Fate becomes the data framework directly** while the app shell stays thin. The shell should own static assets, cookies/session plumbing, routing, and lifecycle. Fate should own reads, mutations/actions, normalized cache updates, and live object/list subscriptions. Do not build a Headplane-specific abstraction layer over Fate's live bus, view resolution, actions, or native HTTP handlers unless a concrete repeated problem appears after using the raw APIs.
+
+Void may still be a useful reference implementation for Fate integration, but it should not drive Headplane's runtime architecture unless it later proves a first-class self-hosted Node mode that fits Headplane's install model.
+
+### Current Fate fit
+
+Fate is directly aimed at the pain Headplane is showing: declarative views, normalized cache, data masking, Async React, optimistic actions/mutations, and live views over SSE. Fate 1.0 says it now includes production-ready live views, Drizzle support, garbage collection, and native HTTP transport. The docs also still contain an alpha warning in the getting-started page, so I would treat the ecosystem as promising but still worth piloting behind a branch.
+
+Headplane is already close on prerequisites:
+
+- React is `19.2.5` and Fate requires React 19.2+.
+- The app already uses Vite 8-era tooling, Vitest, Oxlint, Oxfmt, tsgo, and pnpm.
+- Headplane already has Drizzle, but only for Headplane-local data (`users`, sessions, host info), while core tailnet data comes from the remote Headscale API.
+
+### What Fate would improve
+
+- Replace `LiveDataProvider` + `useRevalidator()` with object/list-level subscriptions (`useLiveView` / `useLiveListView`).
+- Normalize `nodes`, `users`, pre-auth keys, and agent host info instead of passing large loader payloads around.
+- Let components declare data needs near rendering rather than building large page-level loader DTOs.
+- Make mutations return selected updated data and update dependent views without manual `context.hsLive.refresh(...)` calls.
+
+### What Fate will not fix
+
+- API-key-in-cookie session design.
+- Self-linking authorization.
+- Missing route/action capability checks.
+- Headscale config-file write races.
+- WebSSH/WASM lifecycle and SSH host-key verification.
+- Go agent robustness issues.
+
+These should be fixed before or alongside any framework migration.
+
+### Headplane-specific adoption challenges
+
+- **Remote API source:** Fate's Drizzle adapter helps for local DB rows, but `Machine`, `User`, `PreAuthKey`, ACL policy, and DNS/config data mostly come from Headscale REST/config files. A Headscale Fate source/adapter or custom native HTTP query layer would be needed.
+- **Authorization:** Fate views must be scoped by the authenticated principal. Do not reproduce the current process-global cache or mutable API client.
+- **Live events:** Headscale does not appear to push the exact object-level events Headplane needs, so Headplane may still need polling or mutation-triggered `live.update(...)` calls. The win is to send object/list updates to subscribed views, not to revalidate whole routes.
+- **Server framework:** the desired end state is no longer another heavyweight metaframework. Hono is a good fit for the server shell because it uses the Fetch `Request`/`Response` model Fate already targets, while still running as a normal self-hosted Node process.

+
+### Node SEA packaging implications
+
+The SPA direction is a better fit for a Node static SEA than SSR framework mode because the runtime can become one server entry plus a finite static asset set. The server should be structured so that production can first serve assets from `build/client`, then later swap that out for an embedded asset manifest without changing application routing.
+
+Practical constraints for the SEA target:
+
+- keep one explicit production server entry instead of framework-generated adapter code;
+- avoid dynamic runtime imports for route modules in production;
+- make client assets addressable by a generated manifest rather than filesystem discovery;
+- keep mutable data outside the SEA (`data_path`, Headscale config paths, SQLite, logs);
+- preserve direct file serving for large WASM artifacts until we decide whether they should be embedded or adjacent assets.
+
+### Raw Fate rule
+
+Use Fate's public APIs directly:
+
+- `createFateServer(...)` and the native HTTP handler for `/fate`;
+- Fate's live bus directly for `live.update(...)`, `live.delete(...)`, and connection/list invalidations;
+- Fate's context callback directly for request auth and Headscale API access;
+- `FateClient`, `createClient` / `createHTTPTransport` while bootstrapping, then generated `createFateClient(...)` once the Fate Vite plugin has a real server module;
+- `useRequest`, `useView`, `useLiveView`, `useLiveListView`, and Fate actions directly in React.
+
+Do not add project-level wrappers such as `HeadplaneLivePublisher`, `HeadplaneDataContext`, or a custom Fate transport abstraction at the beginning. If raw Fate usage becomes repetitive, extract only the smallest local helper at the repetition site.
+
+### Current scaffold on `tale/fate-spa`
+
+- Removed the earlier `HeadplaneRuntime`, `HeadplaneDataContext`, and `HeadplaneLivePublisher` scaffolding.
+- Added direct dependencies: `react-fate`, `@nkzw/fate`, `@tanstack/react-router`, `@tanstack/router-plugin`, and `@vitejs/plugin-react`.
+- Added a plain Vite SPA `index.html` and `app/spa` entry with TanStack Router and the generated raw Fate client from `react-fate/client`.
+- Moved the old React Router Vite config to `vite-old.config.ts` and replaced `vite.config.ts` with a clean SPA config.
+- Added Hono and `@hono/node-server`, plus a minimal Hono server shell in `app/server/hono-app.ts`, `app/server/hono-dev.ts`, and `app/server/hono-main.ts`.
+- Added `app/server/fate.ts`, which exports a raw Fate server and live bus. Hono mounts Fate's `createHonoFateHandler(fate)` at `/admin/fate` and `/admin/fate/*`, passing the existing app context through Hono variables.
+- Wired the official `react-fate/vite` plugin to `app/server/fate.ts`, ignored generated `.fate/` output, and made `pnpm run typecheck` run `fate generate` before `tsgo` so generated `react-fate/client` typings exist from a clean checkout.
+- Added the first real Fate read roots: `machines` and `users`. They use Fate `dataView(...)`, `list(...)`, and source executors directly, call the existing principal-scoped Headscale runtime API client, and enforce existing `read_machines` / `read_users` capabilities.
+- Added minimal SPA `/machines` and `/users` routes that fetch with raw `useRequest(...)`, render records with `useLiveView(...)`, and subscribe to root list connections with `useLiveListView(...)`. These routes intentionally do not port filters, actions, or optimistic updates yet.
+- Bridged existing `hsLive` resource changes directly to Fate connection invalidations: `nodes` invalidates the `machines` root connection and `users` invalidates the `users` root connection. This is a temporary seam so converted routes can exercise Fate live primitives before the old live store is deleted.
+- Added the first raw Fate mutation, `machine.rename`. It reuses existing `canManageNode` authorization, calls the Headscale API, refreshes the transitional `hsLive` nodes resource, emits direct Fate entity/list live events, and returns the client-selected `Machine` view.
+- `pnpm dev` now runs the Hono/Vite middleware shell with local `.data` storage for the example config; `pnpm build` now runs `vite build` for the SPA.
+- Fate's Drizzle peer currently warns against the repo's Drizzle `1.0.0-beta.21`; avoid Fate's Drizzle adapter until that compatibility is resolved, and start with a direct Headscale source/resolver instead.
+
+### Fate context decision
+
+The current Fate request context should stay pragmatic rather than heavily decomposed:
+
+- expose `api`, the principal-scoped Headscale runtime client, as the primary data access path for remote Headscale data;
+- keep `principal` and `request` available for authorization and future audit/session needs;
+- keep `app` available during the migration so resolvers can reuse the existing auth/config/agent services without inventing a new service layer first;
+- do not pass an unstructured context into every helper by default once a data domain settles. If a `machines`, `users`, or `authKeys` module becomes large, give that module explicit functions that accept the concrete pieces it uses.
+
+In other words: full app context is acceptable as migration scaffolding, but the resolver code should prefer the smallest direct dependency (`ctx.api`, `ctx.app.auth`, etc.) and should not become a new `HeadplaneRuntime` abstraction.
+
+### Recommended migration sequence
+
+1. **Remove transitional abstractions** and make the branch clearly one-way toward SPA + raw Fate.
+2. **Install the direct dependencies**: `react-fate`, `@nkzw/fate`, `@tanstack/react-router`, `@tanstack/router-plugin`, and the plain Vite React plugin if the React Router plugin is removed.
+3. **Replace the build/dev entry shape**:
+   - add a Vite SPA entry and TanStack route tree;
+   - stop generating new React Router route types;
+   - keep the existing Node server entry as the self-hosted process.
+4. **Mount raw Fate endpoints** in the current Node request path:
+   - `/fate` for native RPC;
+   - `/fate/live` for SSE and subscription control;
+   - request context resolves auth using the existing auth service and calls `context.hsApi.getRuntimeClient(...)` directly.
+5. **Convert the machines page first** using raw Fate views and live list/view hooks.
+6. **Add live updates to the converted lists** by publishing Fate list/entity invalidations from the existing polling/mutation seams. Keep this raw Fate live bus usage, not a Headplane live wrapper.
+7. **Port one mutation at a time**, starting with a low-risk machine mutation such as rename. The mutation should call the existing Headscale API, return the selected entity, and emit the relevant Fate live event.
+8. **Delete the old React Router loader/action/SSE path for converted data**, rather than running duplicate data models side-by-side.
+9. **Fix critical auth/session issues early**: self-linking, raw API-key cookie, agent-route authz.
+10. **Keep runtime changes minimal** until the SPA actually needs them: Hono routes, static SPA fallback, Fate routes, and later SEA asset serving.
+
+### Vite+ / VoidZero tooling assessment
+
+Vite+ is a unified CLI (`vp`) for Vite, Vitest, Oxlint, Oxfmt, Rolldown, tsdown, type checking, package-manager/runtime management, and task caching. Headplane already uses most of these tools separately, so Vite+ would mostly consolidate tooling and improve task ergonomics; it will not solve the data-layer problems by itself.
+
+Recommended Vite+ approach:
+
+- Try `vp migrate` in a separate branch only after adding CI typecheck/lint gates.
+- Expect manual work around the custom React Router SSR entry and `runtime/vite-plugin.ts`.
+- Do not combine Vite+ migration with Fate/Void/router migration in the same PR.
+
+## Suggested immediate backlog
+
+1. Replace the temporary `hsLive` bridge with direct Fate events from converted mutations and, if needed, a principal-safe polling source.
+2. Move the machine rename UI out of the throwaway table row controls once the permanent SPA machines page layout exists.
+3. Port the next machine mutations: expire/delete/tags/routes, one at a time, each returning selected data or deleting/updating the normalized cache explicitly.
+4. Fix OIDC self-linking authorization.
+5. Make API-key sessions opaque/server-side and set explicit auth cookie flags.
+6. Add capability checks to `/settings/agent` loader/action.
+7. Fix live-data pause cleanup/refcounting for unconverted React Router routes.
+8. Make `hsLive` use a stable server credential or principal-scoped cache while it still exists.
+9. Serialize config patches with a real mutex/queue and clone config arrays before editing.
+10. Add CI `pnpm run typecheck` and `pnpm run lint`.
+11. Add WebSSH top-level dispose and release Go `js.Func` values.

-# TLS & Certificates
-
-Everything Headplane does with TLS lives on this page: terminating HTTPS
-in-process, trusting private certificate authorities for outbound
-connections, and the interactions with cookies and the bundled Docker
-healthcheck.
-
-## Custom Certificate Authorities
-
-If you front any of the services Headplane talks to — your Headscale server,
-your OIDC provider, an HTTPS Docker daemon, etc. — with a private or
-self-signed certificate authority, Headplane needs to trust that CA. The
-cleanest way to do that is the standard Node.js `NODE_EXTRA_CA_CERTS`
-environment variable, which is honoured for **every** outbound TLS
-connection in the process (OIDC discovery, Headscale API, Docker, anything
-else that uses `fetch` or `https`).
-
-Provide it as a path to a PEM-encoded bundle of one or more CA certificates:
-
-```bash
-NODE_EXTRA_CA_CERTS=/etc/headplane/extra-cas.pem
-```
-
-In Docker, bind-mount the bundle and pass the variable through:
-
-```yaml
-services:
-  headplane:
-    image: ghcr.io/tale/headplane:latest
-    environment:
-      NODE_EXTRA_CA_CERTS: /etc/headplane/extra-cas.pem
-    volumes:
-      - "./internal-ca.pem:/etc/headplane/extra-cas.pem:ro"
-      - "./config.yaml:/etc/headplane/config.yaml"
-      - "./headplane-data:/var/lib/headplane"
-```
-
-The bundle is added **on top of** the system trust store, so public
-certificates (Let's Encrypt, ZeroSSL, etc.) keep working.
-
-> `headscale.tls_cert_path` is a narrower knob that pins Headscale's API
-> connection to exactly one certificate, bypassing the rest of the trust
-> store. It still has its place if you want Headplane to refuse anything
-> other than that specific cert for Headscale, but `NODE_EXTRA_CA_CERTS` is
-> the right tool whenever you simply want to add a CA to the trusted set.
-
-## TLS Termination
-
-Headplane can terminate TLS itself when both `server.tls_cert_path` and
-`server.tls_key_path` are set in the configuration file. Both must point to
-PEM-encoded files that Headplane can read.
-
-```yaml
-server:
-  port: 443
-  tls_cert_path: "/var/lib/headplane/tls/fullchain.pem"
-  tls_key_path: "/var/lib/headplane/tls/privkey.pem"
-```
-
-When TLS is configured Headplane serves HTTPS/1.1 on `server.port`. HTTP/2
-and HTTP/3 are intentionally not supported in-process — terminate those at a
-reverse proxy (e.g. Caddy or Traefik) and forward to Headplane over HTTP/1.1
-if you need them today.
-
-`server.cookie_secure` is forced to `true` whenever TLS is enabled (browsers
-refuse `Secure`-less cookies over HTTPS); a warning is logged if your config
-had it set to `false`.
-
-For most deployments we still recommend terminating TLS at a reverse proxy
-(see [Reverse Proxying](./#reverse-proxying)) so you can share certificates
-with Headscale and other services. Built-in TLS is meant for the simpler
-"Headplane on a single box" scenarios.
-
-## Healthcheck
-
-The bundled Docker healthcheck picks up the right scheme and port
-automatically — Headplane writes its loopback URL to `/tmp/headplane-listen`
-when it starts, and the healthcheck reads it from there. So flipping TLS on
-or off requires no healthcheck-specific configuration; everything just
-works.
