Can I vibecode Inbox Zero?

Build me a self-hosted personal Gmail assistant that covers the core Inbox Zero loop.
Use Node 22 + TypeScript + Fastify + better-sqlite3; server-rendered HTML and vanilla JS, no React.
Run on localhost by default, with one Dockerfile for an always-on VPS behind Caddy.
Support exactly one Gmail or Google Workspace mailbox through the Gmail API.
Use a Google OAuth client from .env and request only gmail.modify and gmail.compose; store the refresh token encrypted with an APP_SECRET.
On first run, import 14 days of mail; then poll Gmail history every two minutes and persist the last history ID.
Deduplicate jobs by Gmail message ID, use exponential backoff for transient API failures, and surface a failed-jobs page.
Rules live in rules.md: label definitions, priority senders, newsletters, cold email, and messages that need a reply.
For each new thread, call the OpenAI API with the thread text plus rules.md and require validated JSON: labels, priority, needsReply, summary, and optional draftReply.
Apply Gmail labels automatically, but never archive, delete, unsubscribe, or send without a click.
When needsReply is true, create or update a Gmail draft in the original thread; never send mail from the app.
Build one dashboard with Priority, Needs reply, Newsletters, Cold email, and Failed jobs views.
Add a bulk-cleanup screen grouped by sender with message counts and List-Unsubscribe support; show the exact action and require confirmation.
Add a small analytics page: daily received count, top senders, category totals, and estimated time saved.
Store only IDs, classifications, job state, and draft metadata in SQLite; do not persist full message bodies after processing.
Redact tokens and email contents from logs; add CSRF protection and bind the admin UI to localhost unless ADMIN_TOKEN is set.
Include fixture-based tests for classification parsing, idempotent sync, label application, draft creation, and unsubscribe confirmation.
Out of scope: Outlook, multiple accounts, mobile apps, Slack/Telegram, calendar context, attachment filing, multi-user accounts, billing, and telemetry.
README: exact Google Cloud OAuth setup, scopes and redirect URI, .env example, how to revoke access, Docker/Caddy deployment, backups, and expected LLM costs.
Return finished code with migrations and scripts for dev, test, and start; no pseudocode or TODOs.
