The launch gate cannot configure or verify the required DLQ-depth and 5xx-rate alerts because it points operators to docs/observability.md, which is absent from the repository. Add that document with the alert thresholds and destinations, or update the checklist to reference the document that contains them.

server.allowedHosts: true disables Vite's host allowlist, so a DNS-rebound hostname can reach the 0.0.0.0 dev server and retrieve source/content before SvelteKit's host-gate runs. Replace this with an explicit allowlist of the development hostnames (or remove the override to use Vite's defaults).

🔴 Critical src/hooks.server.ts:74
For an HTTP DASHBOARD_ORIGIN, the refresh path sets the authenticated session without the Secure attribute, so browsers transmit the bearer cookie over cleartext on every subsequent request. HttpOnly and SameSite do not prevent network interception or replay; enforce HTTPS for the dashboard origin and reject HTTP rather than issuing this session cookie.

PlanetScale's automatic backups are the primary copy, the home-host pg_dump the independent one, and R2 gets object versioning or a second bucket. The backup host installer now checks for pg_dump beside rclone. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Public pages, abuse and DMCA contacts, content-zone settings, the secrets that must exist before the first deploy, and the verification skill as the final gate. release.md links to it from first-time setup and the README intro now describes the hosted direction while keeping the self-hosting instructions.

Browsers refuse Secure cookies on http origins other than localhost, so signing in from a LAN or Tailscale hostname in development silently lost the session. The cookie names and Secure flag now follow the dashboard origin's scheme. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Keep Vite’s host allowlist enabled.
When the dev server listens on 0.0.0.0, allowedHosts: true accepts attacker-controlled hostnames. Vite serves development assets outside the SvelteKit request hook, so assertHostRoute does not protect that surface. Vite 8 warns that this setting permits DNS-rebinding access to source code and content. Remove the override and use the documented __VITE_ADDITIONAL_SERVER_ALLOWED_HOSTS setting for the required remote hosts. (v8.vite.dev)

If an attacker-controlled hostname resolves to a reachable development server, allowedHosts: true lets it request Vite's application modules even though the application's host gate rejects that hostname. This exposes transformed application source that the previous host restriction blocked. Restrict Vite to the development hostnames that are needed.
How this was verified: The hostile hostname received application modules with HTTP 200 while application routes returned HTTP 421; the previous configuration returned HTTP 403 for those modules.
Artifacts
Executed HTTP Host comparison probe
- The source starts each Vite configuration and requests app and module routes with hostile and localhost Host headers; its upload status is unverified.
Previous configuration rejects the hostile Host
- The captured run records HTTP 403 Forbidden for attacker.example requests under the previous configuration; its upload status is unverified.
Current configuration serves modules to the hostile Host
- The captured run records HTTP 200 OK for Vite modules and HTTP 421 Misdirected Request for app routes under attacker.example; its upload status is unverified.

Fix authentication on remote HTTP development origins and align operations with the hosted stack. Cookies use origin-appropriate names and deletion options, device approval survives sign-in, and Vite accepts only explicitly allowed development hosts. Uploads and notifications use secure random ephemeral IDs available on HTTP origins.
Launch, restore, observability, and deployment skills now describe the hosted services. Recovering historical site publications requires a matching earlier database snapshot and retained object bytes; synthetic version markers cannot reconstruct historical paths.
Validation:
Stack layer 11/12: depends on #38; followed by #40. Live WorkOS, DNS/TLS, provider alerts, paid sandbox flows, and restore drills remain launch checks. No merge or deployment.
Note
Prepare hosted operations, remote development setup, and origin-based auth cookies

allowedHosts: truedisables Vite's host allowlist for the LAN-bound development server. Vite documents that this permits DNS-rebinding requests to download the dev server's source and content; the SvelteKit host gate cannot protect Vite's own development endpoints. A malicious site can therefore expose a developer's checked-out source whenever it can reach this server. [ Already posted ]Safe to merge.
