Beta Launch Execution Plan

The path from "shipping to ourselves" to "510 friendly testers can use Vibn end-to-end without us hand-holding."

Companion to: AI_PATH_B_EXECUTION_PLAN.md (architecture) and AI_CAPABILITIES.md (current state).

Drafted: 2026-04-30. Owner: Mark + AI.

Scope: Everything we agreed in the 2026-04-30 review that's NOT already shipped. Pulls in the unfinished items from Path B (DNS, cert, previews, eval) AND the "before strangers see this" gaps that Path B doesn't cover (runtime errors, error surfaces, onboarding smoke test, landing page, safety rails).


North star for the beta

A non-technical founder receives a Vibn invite link, signs up, describes what they want to build, sees a working preview within a few minutes, can iterate on it through chat without seeing a stack trace, and can ship it to a real domain — all without us reaching into Coolify on their behalf.

If any of those steps requires us in the loop, beta isn't ready.


Phase ordering

Sequenced by leverage × blocking risk. Earlier phases unblock later ones.

Model assignment convention

Opus is reserved for judgment-heavy work — anything that touches multiple subsystems, has security implications, designs a protocol, or requires reading existing architecture before deciding what to ship. Mechanical, well-specified work goes to a cheaper coder model.

Per-task tags inside each Phase table:

  • opus — architectural, cross-cutting, security-sensitive. Opus reads the relevant code, decides the approach, writes the code.
  • cheap — well-specified, single-file or local-scope, pattern exists. Cheaper model executes from the row's notes.
  • opus-spec → cheap — Opus writes a tight one-paragraph spec in the row's notes (schema columns, function signature, exact files to touch); cheaper model implements verbatim.

If a row has no model tag, default is cheap. The expensive default is opt-in, not opt-out.


Phase 1 — Previews unlock — SHIPPED 2026-05-01

Goal: dev_server.start returns a clickable https://*.preview.vibnai.com URL that loads in <30s, with HMR working over the proxy.

Why first: the single biggest UX cliff today is "user iterates → 3-7 min Coolify build". Previews collapse it to seconds. Everything else is polish on a slow loop until this lands.

# Task Owner Effort Status

Definition of done: AI says "open a Vite dev server", user clicks the URL, sees Vite's welcome page, edits a file via fs.edit, change appears in browser within 5s without manual reload.

Verified Vite config for HMR through Traefik (the system prompt should advertise this exact shape when scaffolding Vite projects):

server: {
  host: '0.0.0.0',
  port: 3001,            // any 30003009
  strictPort: true,
  hmr: {
    clientPort: 443,
    protocol: 'wss',
    host: 'preview-{slot}-{slug}-{token}.preview.vibnai.com',
  },
}

Phase 2 — Stability & visibility

Goal: when something breaks in production, we hear about it before users do.

# Task Owner Effort Notes
2.1 Reproduce + diagnose ERR_HTTP_HEADERS_SENT from prod logs AI 12 hrs Likely a server action / API route returning twice
2.2 Reproduce + diagnose TypeError: reading 'z'/'j'/'aa' in prod bundle AI 12 hrs Minified prod error; suspect react-markdown server/client boundary

Definition of done: force-fail a route in staging → Sentry alert lands in < 1 min. Force-fail a Coolify deploy → notification fires. Reproduce an orphan-container conflict in prod → model calls apps_unstick instead of delete-and-recreate.


Phase 3 — UX surfaces (what users actually touch)

Goal: every screen a beta tester lands on either does something useful or gets out of the way. No screens that exist "to teach the data model".

# Task Owner Effort Notes
3.1 Hosting tab rewrite — focus on the domain (live URL, redeploy, env, logs) instead of master-detail of "live + previews" AI 4 hrs Mark flagged earlier
3.2 Replace the chat's "⚠️ Failed to get response. Please try again." with structured errors that show what tool failed and why AI 2 hrs Critical — currently zero feedback
3.3 Empty states across Plan/Product/Infrastructure/Hosting that suggest the next AI prompt to try (not just "nothing here") AI 2 hrs Vibe coders need a nudge
3.6 Product tab: confirm it's actually useful day-to-day. Revise scope if not Mark + AI 1 hr Open question
3.7 Scope-doc upload in Plan tab — drop a PDF/.md/.docx/.txt as the project brief; server extracts text, stores on fs_projects.brief_text + brief_meta, exposes via [PROJECT BRIEF] block in system prompt and a project_brief MCP tool for on-demand grep. New file: lib/integrations/brief-extract.ts. Empty state replaces "nothing here" on Plan. AI 3 hrs Came up during smoke test prep — users will arrive with scope docs (PDF/Notion-export/Doc); right now there's no way to hand the AI the source of truth except paste-into-chat.
3.8 "Stop at something tangible" — three layers AI partially done Came up watching Manifest scaffold — AI stopped at "everything is wired together" with no preview, leaving the user to wonder if any of it was real. Code on disk is invisible; preview URL is the proof.
3.8c Server-side enforcement: if a turn called fs_write ≥10 times for source files but never dev_server_start or apps_deploy, append a synthetic recovery instruction telling the model to either start a server or explain the blocker AI 1 hr Safety net for when the model ignores the prompt rule under load. Add a tracker in app/api/chat/route.ts tool loop, fire the instruction inside the round 2 system message.

Definition of done: a stranger lands on every tab in turn. None of them make us cringe. Each one either shows useful info or gives the user a concrete next action.


Phase 4 — Onboarding & safety

Goal: a stranger with the invite link can get from "what is this" to "I shipped a thing" without us in the chat.

# Task Owner Effort Notes
4.1 End-to-end smoke test on a fresh account: signup → workspace → project → first chat → first preview → first deploy Mark + AI 2 hrs Walk through with an empty cookie jar; fix everything broken. Runbook below.
4.2 Landing page at vibnai.com that explains the product in 30s Mark + AI 4 hrs Currently a login screen
4.4 "Delete workspace" UI — same AI 1 hr
4.5 Auth hardening pass: NextAuth session expiry, CSRF on mutating routes, GitHub OAuth scope review AI 2 hrs
4.7 Per-workspace audit log of mutating MCP calls (apps/databases/services create/delete) AI 2 hrs We need this when something goes wrong
4.8 Invite link / waitlist page (manual approval) so we control who joins Mark + AI 1 hr

Definition of done: Mark hands the invite link to one non-developer friend, they get to "shipped a thing" without messaging Mark for help.


Phase 5 — Path B closeout

Goal: finish the architectural commitments in AI_PATH_B_EXECUTION_PLAN.md that aren't covered above.

# Task Owner Effort Notes
5.2 Hard-remove gitea_file_* from the AI tool list; keep REST routes alive 30 days with deprecation header AI 1 hr Path B week 3 task
5.3 Update AI_CAPABILITIES.md to reflect everything that shipped AI 1 hr
5.4 Eval harness: 10 reference prompts, measure time-to-first-preview, time-to-shipped, tool-call count, success rate AI 12 days The actual proof Path B works
5.5 Theia / openvscode-server toggle: "Open IDE" button in chat → https://ide-{ws}-{project}.vibnai.com AI 4 hrs Week 4 nice-to-have; gates the "user becomes developer" graduation
5.6 Idle-suspend cron — wire POST /api/admin/path-b/idle-sweep to a 5-min schedule once we trust it AI 30 min Keeps cost bounded

Definition of done: eval harness reports ≥3× speedup on time-to-first-preview vs. Path A baseline, ≥80% success rate across the 10 reference prompts.


Phase 6 — Artifact-first UX (Bolt parity, Vibn taste)

Goal: the running app is the dominant surface on every project page, not a thing-to-summon. The user should never have to wonder if the AI actually built something — it's right there. Lift the structural patterns Bolt/Lovable/v0 have proven (two-pane, preview chrome, plan- as-checklist) without the dark glassy aesthetic.

Why now (after smoke test prep): today the AI can scaffold a full six-service stack and a non-technical founder still has no idea where "their app" is. The composer chip + header Preview button (3.8) helped, but the structural fix is two-pane.

# Task Owner Effort Model Notes
6.A1 Two-pane structural refactor — replace app/[workspace]/project/[projectId]/(home)/layout.tsx shell. Workspace sidebar (unchanged) → main column: horizontal icon bar (👁 / ⟨⟩ / … / ⚙) above a row of permanent chat ~380px + pure artifact pane. Bar spans full width above chat+content so the vertical strip does not steal horizontal space from the preview. Default view = Preview. Coordinates with existing ProjectStagePill, ProjectAssociationPrompt, --chat-panel-width CSS var (obsolete on project pages). AI 3 hrs opus Cross-cutting; touches layout, chat panel, header. Has to keep ProjectHeaderUrls working.
6.A2 PreviewPane component — iframe of `previewUrl fqdn, with empty-state placeholder ("Your preview will appear here" + Vibn V mark). Reads from useAnatomy(). Exports kind: "preview"` rendered by 6.A1's right pane. AI 1 hr
6.A3 Iframe chrome (artifact-local) — top-right of the iframe: ↻ reload (force iframe key bump), ↗ open-in-new-tab, ⛶ fullscreen (toggles a panel-level expanded state that hides chat column), 📱 device-frame (desktop / tablet / mobile widths, persisted to localStorage per-project). AI 1 hr cheap Pure UI. Width tokens: desktop=100%, tablet=820px, mobile=390px. Frame is a CSS wrapper, not real device emulation.
6.A4 Code view — when ⟨⟩ is selected on the rail, render the existing gitea-file-tree.tsx + gitea-file-viewer.tsx in the right pane. Two-column inside the right pane: tree on the left, viewer on the right. AI 30 min cheap Components already exist; just compose them. Shared selectedPath state.
6.A5 Resources view — when 🗄 is selected, render the existing database-table-tree.tsx + table-viewer.tsx plus a small list of running services (from anatomy.hosting.live[] and apps_containers_list). AI 1 hr cheap Same wire-up pattern as 6.A4.
6.B1 Persist last-known dev server config — new table fs_project_dev_servers (project_id PK, command, port, framework, last_started_at, status). Hook dev_server_start MCP tool to upsert on success; dev_server_stop to flip status. AI 1 hr opus-spec → cheap Spec: schema is project_id UUID PK, command TEXT NOT NULL, port INT NOT NULL, framework TEXT, last_started_at TIMESTAMPTZ, status TEXT CHECK IN ('running','stopped','crashed'). Migration in lib/db-postgres-migrations.ts pattern. Upsert in lib/dev-server-manager.ts (or wherever dev_server_start lives — find via Grep).
6.B2 Auto-resume dev server on project page mount — server-render hook on the new layout: if (a) saved server config exists AND (b) getDevContainerStatus() returns running or provisioning AND (c) no live preview already in useAnatomy().hosting.previews[] → fire the saved dev_server_start server-side BEFORE the page paints. User lands; preview is live. AI 2 hrs opus Risky if naive — could resume a server the user explicitly stopped, could thrash on idle-suspended containers, could race the existing on-mount devcontainer_ensure. Needs careful state-machine read. Idempotency comes from dev_server_start returning alreadyRunning: true when a process matches command+port.
6.C1 SSE plan event protocol — server emits { type: "plan", taskId, text, status: "queued"|"in_progress"|"done" } whenever plan_task_add / plan_task_complete (or a new plan_task_start) MCP tool fires inside a chat turn. Coexists with existing text and toolCall events. AI 2 hrs opus Protocol design — has to handle ordering (plan event must land before the tool's toolResult), client-side reconciliation with fs_projects.plan.tasks[] on next page load (server is source of truth, SSE is a hot stream), and the case where the AI calls plan_task_complete for a task added in a prior turn.
6.C2 Client TimelineEntry of kind: "plan" — render a checklist with status circles (○ queued / ◐ in-progress / ● done) inside the assistant message timeline. Each new plan SSE event upserts by taskId. Ledger pattern matches the existing kind: "text" / kind: "tool" rendering in chat-panel.tsx. AI 1.5 hrs opus-spec → cheap Spec written into 6.C1's notes. Visual: indented under a "Plan" mini-header, same Outfit/Newsreader palette, status circles in #a09a90#3a3530#1a1a1a.
6.C3 Share + Publish buttons on the new shell — top-right of the right pane (next to artifact chrome). Share = copy previewUrl || fqdn. Publish = fire existing ship MCP tool with auto-generated commit message. AI 30 min cheap Both are existing tool calls; just buttons.
6.D1 ⚙ Settings popover — single popover off the icon rail's ⚙. Sections: Domain (shows current fqdn, link to rename), Sentry (link to project's Sentry dashboard from projects.get), Secrets (links to 6.D2), Quick-add database (fires 6.D3 modal), All project settings (link to /[workspace]/project/[id]/settings). AI 1 hr cheap Pattern matches existing project-header-urls popover.
6.D2 Project-level secret scratchpad — new table fs_project_secrets (project_id, key, value_encrypted, created_at, updated_at). Encryption-at-rest via existing lib/crypto.ts (or scaffold one if absent — use AES-GCM with a workspace-scoped key derived from a master VIBN_SECRETS_KEY env). MCP tools: secrets_get { projectId, key }, secrets_set { projectId, key, value }, secrets_list { projectId } (returns keys only). AI can read/write user-supplied API keys before they're injected into a deploy. AI 2 hrs opus Security-sensitive: encryption scheme, key rotation story, tenant isolation, what gets logged. Needs careful handling, not pattern-matching.
6.D3 Quick-add database modal — fires databases_create MCP tool, blocks until databases_get returns a connection URL, surfaces the URL with a copy button + "I'll inject this into your app's env" affordance that calls apps_envs_set if a target app exists. AI 1 hr cheap Each step is an existing MCP call; modal orchestrates them.

Definition of done: open any project that's been built, the running preview is already live in the right pane without clicking anything; clicking ⟨⟩ shows the source tree; clicking 🗄 shows the databases; the AI's plan streams in as a checklist instead of paragraphs; ⚙ opens a single popover with all project config one click away.

Sequencing inside Phase 6:

6.A1 (structural) ──> 6.A2..A5 (panels)  ──┐
                                            ├── 6.D1 (settings popover)
6.B1 (persist) ──> 6.B2 (auto-resume)  ──┘
6.C1 (SSE)   ──> 6.C2 (client renderer) ──> 6.C3 (share/publish)
                                          └─ 6.D2 (secrets) ── 6.D3 (db modal)

A-track is the user-visible spine. B-track makes the spine populated on first paint. C-track makes the AI feel like it's working. D-track fills the settings drawer.

Out of scope for Phase 6 (intentional cuts, captured here so they don't get pulled in):

  • Built-app authentication scaffolding (auth-as-a-service for users' apps) — multi-week, real product call.
  • First-party connectors marketplace (Stripe / Twilio "click to add") — multi-week per integration. AI can install via shell today.
  • Multi-model picker / "Plan vs. Build" toggle on the composer — defer until BYOK lands and we have something to switch between.
  • Design-system picker on the composer — real product call.
  • Knowledge-base / RAG beyond scope-doc upload (3.7).
  • Server functions à la Bolt — different deploy model, not a gap.
  • Mobile preview QR — only matters once mobile is a real target.

Sequencing & dependencies

                                                          │
                                                          ├─ P5 (parallel; some pieces gated by P1)
                                                          │
                                                          └─ P6 (gated by P1 + P5.7;
                                                                 6.A1 unblocks the rest)

P1 is the long pole. P6 is the next big-leverage move once smoke test passes — pre-invite UX upgrade, depends on previews (P1) and the auto-clone wiring (5.7) both being solid.


Suggested cadence

  • Today (in flight): P1.1 — Cloudflare signup + record verification.
  • Tonight / tomorrow: P1.2P1.8 once nameservers propagate. AI does the cert + Traefik wiring; Mark does the clicks at Cloudflare/Namecheap.
  • Day 2: P2.1P2.3 (runtime error chase + Sentry) + P3.1 (Hosting rewrite) in parallel.
  • Day 3: P3.2P3.6 + P4.1 smoke test.
  • Day 4: P4.2 landing page + P4.3P4.5 deletion/auth.
  • Day 5: P4.6P4.8 quotas/audit/invite + P5.1 vibn-dev image.
  • Days 610: P5.2P5.6 closeout, eval harness, polish, then invite first testers.

10 working days from today to "first 5 testers". Tight but doable if no nasty discoveries in P2.


What we are not doing for beta

Logged so we don't accidentally pull them in:

  • Stripe / billing (post-beta — we want to know what to charge for first)
  • Mobile-responsive polish (desktop-first beta)
  • Multi-region Coolify (single-host is fine for <50 users)
  • Replacing Coolify (out of scope; Path B is the abstraction over it)
  • Replacing Gitea (Path B's shell.exec already abstracts most of it)
  • Plugin marketplace, template marketplace, monetization paths
  • Anything requiring us to redo NextAuth / migrate to a different auth
  • Theme system / dark mode

Risks specific to this plan

Risk Mitigation
Cloudflare DNS propagation breaks email forwarding We pre-verified MX records in the audit; double-check at Cloudflare review screen before switching nameservers
Traefik wildcard cert acquisition fails on first try DNS-01 against Cloudflare is well-trodden; if it fails it's fixable, not catastrophic. Old certs keep serving until replaced.
Runtime errors in P2 turn out to be a deeper architectural issue Time-box investigation to 4 hrs each; if not solved, document workaround and ship anyway, debug after invite
Eval harness reveals Path B is slower than promised Acceptable to invite testers without 100% Path B coverage as long as the prod-deploy-only path works. Path B is an upgrade, not a gate.
New users hit 100 unforeseen edge cases This is the point of beta. Triage daily, fix the top-3 each morning.

Smoke-test runbook (4.1)

Goal: prove the user-visible flow from "first visit" through "shipped a deployed app" works end-to-end with all the new wiring (Sentry per-project, quotas, recovery middleware, URL chip popover, status-pill deep-link, deploy-failed Slack alerts).

Setup: open an incognito window. Have your Slack channel and Sentry dashboard visible in side tabs. You'll be the fresh user.

Steps

  1. Visit https://vibnai.com → sign up with Google (use a different gmail than your normal one if possible — keeps test data clean). Confirm you land on the workspace home.
  2. Create a project (any path: build / oss / import). Pick a slug like smoke-test-2026-05-01.
    • Verify in Sentry: within ~10s, a new project named vibn-{your-workspace-slug}-smoke-test-2026-05-01 should appear at https://vibnai.sentry.io/projects/.
    • Verify in DB (optional): fs_projects.data.sentry.dsn is populated for the new row.
  3. Land in chat. AI should greet you and offer to scaffold something. Ask it to build something simple ("a Next.js todo app").
  4. Watch the preview start. AI should call devcontainer_ensure, scaffold, then dev_server_start. A preview URL like preview-0-{slug}-{token}.preview.vibnai.com should be returned. Click it. Page should load over HTTPS with a valid cert.
  5. Edit something via chat. Ask AI to add a button or change copy. HMR should update the preview without reload.
  6. Ship it. Tell AI "ship it." It should apps_create against your Gitea repo + trigger Coolify deploy. Watch the project header status pill go Empty → Deploying → Live.
    • Verify in Coolify env: the new app's env vars include NEXT_PUBLIC_SENTRY_DSN and SENTRY_AUTH_TOKEN.
    • Verify Slack: if the deploy fails for any reason, your Slack channel pings within 30s. If it succeeds, no message (by design — we're noise-conscious).
  7. Trigger a real error in the deployed app. Open the live URL, click around until something breaks. (If nothing breaks, ask AI to add a button that calls myUndefinedFunction().)
    • Verify in Sentry: the error lands in the new Sentry project within ~10s, with a real stack trace (file/line in your project's source). Session Replay should be available.
    • Open a new chat with this project and say "what's broken?" → AI should call project_recent_errors and surface the issue with a fix suggestion. This is the killer-feature path.
  8. Hit the quota cap. Try to create a 4th project. Should get a friendly 402 with the "delete one or contact support" wording, NOT a generic error. AI in chat should explain the cap clearly without retrying.
  9. Test the URL chip popover. Once you have ≥4 URLs on a project (e.g. preview + live + 2 services), the project header should collapse to 3 chips + a +N pill. Click it; popover opens with the rest as clickable links. Click outside; popover closes. Press Escape; closes.
  10. Test the status-pill Logs link. During a deploy, the "Logs" link next to the pill should one-click into the Coolify project page (not the root).

What to do when something breaks

  • Take a screenshot, open a Vibn chat in a separate (parent-account) tab, paste the screenshot, and say "this just broke during smoke test." AI now has Sentry access + can read recent errors itself.
  • If a step is very broken, file a P0 against this checklist with the step number and what you saw.

Pass criteria

  • All 10 steps complete with no manual intervention by the AI's parent operator.
  • Every "Verify" line returns the expected positive signal.
  • Worst case the AI surfaces is a quota cap or known-recoverable error — never a generic "something went wrong."

How to use this doc

  • Treat phase boundaries as soft. If a P2 task unblocks a P3 task and you're there, do it.
  • When a task ships, check it off and move it under "Shipped" in AI_CAPABILITIES.md.
  • When the plan changes (it will), edit this doc directly, don't fork it.
  • Beta success criteria: 5 testers, all reach "shipped a thing", weekly active rate >60% in week 2. If we miss those, the next plan is "what did we get wrong."
