 ## [1.0.0-rc.2] - 2026-05-24
 
-TomoeJS graduates to a complete, production-ready Release Candidate (`1.0.0-rc.2`)! This release brings a massive sweep of security hardening upgrades, routing optimizations, advanced middlewares, comprehensive validation enhancements, and a fully polished, zero-dependency web standard core.
+TomoeJS continues as a production-readiness Release Candidate (`1.0.0-rc.2`). This release brings security hardening upgrades, routing optimizations, advanced middlewares, validation enhancements, and a zero-dependency web standard core. Treat it as an RC until the release gates in `docs/production-readiness.md` are complete.
 
 ### 🌸 The Power of Tomoe (Key Highlights)
 * **Contract-Driven Correctness**: Declared relics and guards are validated and compiled at startup (`app.compile()`), throwing immediately on broken dependency chains rather than crashing silently in production.

+# Contributing
+
+## Development Setup
+
+```bash
+pnpm install
+pnpm type-check
+pnpm lint
+pnpm test
+pnpm build
+```
+
+Use small pull requests with a clear reproduction or use case. For framework behavior changes, include tests that fail before the change.
+
+## Compatibility Rules
+
+Tomoe is still in release-candidate status, but public API changes should be handled deliberately.
+
+- Avoid breaking route registration, middleware, relics, guards, context helpers, and adapters unless the change is required for correctness or security.
+- Document breaking changes in `CHANGELOG.md`.
+- Add migration notes for renamed APIs or changed runtime behavior.
+- Prefer additive APIs over replacing existing behavior.
+
+## Test Expectations
+
+Production-facing changes should include tests for at least one of:
+
+- Runtime behavior through `app.fetch`.
+- Type inference when public types change.
+- Adapter behavior for Node or Bun.
+- Error handling and edge cases.
+- Security-sensitive behavior such as headers, cookies, CSRF, validation, or body parsing.
+
+## Benchmarks
+
+Benchmarks are useful only when they are reproducible. Benchmark PRs should include:
+
+- Runtime versions.
+- Operating system and CPU.
+- Exact command.
+- Raw output or generated report.
+- Multiple runs or a note that results are single-run only.
+
+Do not update README performance claims without updating benchmark evidence.

+
+## Supported Versions
+
+Tomoe is currently in release-candidate status. Security fixes target the latest published release candidate unless the maintainers announce otherwise.
+
+| Version | Supported |
+| --- | --- |
+| 1.0.0-rc.x | Yes |
+| < 1.0.0-rc | No |
+
+## Reporting a Vulnerability
+
+Do not open a public issue for a suspected vulnerability.
+
+Email the maintainers or use GitHub private vulnerability reporting when enabled. Include:
+
+- Affected Tomoe version.
+- Runtime and version: Bun, Node.js, Deno, Cloudflare Workers, or another adapter.
+- Minimal reproduction code.
+- Expected and actual behavior.
+- Impact assessment, including whether the issue enables data exposure, auth bypass, denial of service, request smuggling, header injection, or cross-site request forgery.
+
+The project should acknowledge reports within 7 days and provide a fix, mitigation, or status update within 30 days for confirmed vulnerabilities.
+
+## Security Boundaries
+
+Tomoe provides routing, middleware execution, schema validation hooks, cookie serialization checks, CSRF middleware, and in-memory rate limiting. Applications remain responsible for:
+
+- Authentication and authorization policy.
+- Secret storage.
+- Database query safety.
+- Body-size limits at the reverse proxy, runtime, or adapter layer.
+- TLS termination and proxy configuration.
+- Persistent or distributed rate limiting.
+- Escaping user-controlled HTML.
+- Logging redaction for credentials, cookies, and personal data.
+
+## External Review
+
+Before a stable 1.0 release, the project should complete an external security review covering the router, Node adapter, middleware chain, schema validation, cookies, CSRF, OpenAPI generation, and denial-of-service behavior.

 ## Summary of Findings
-1. **TomoeJS (Bun)** executes with extreme high-throughput, placing it side-by-side or ahead of frameworks like Hono and Elysia.
-2. **TomoeJS (Node)** runs significantly faster than legacy frameworks like Express due to its lightweight core and absence of dynamic middleware pipeline scans.
-3. **Pre-compiled Onion Execution** saves CPU cycles, resulting in better latency profiles on highly composed routes.
+1. **TomoeJS (Bun)** was competitive in these single-host, short-duration measurements, but the per-scenario tables should be treated as the source of truth.
+2. **TomoeJS (Node)** is slower than Express in this historical report because it uses the Web Request/Response adapter path on Node.
+3. **Pre-compiled middleware execution** remains the hypothesis to verify with repeated runs, raw output, variance, and target-platform measurements.

+
+## Reverse Proxy Guidance
+
+Set these at the proxy or platform layer:
+
+- Maximum request body size.
+- Request timeout and idle timeout.
+- TLS termination.
+- Trusted proxy headers.
+- Access logs with sensitive header redaction.
+
+For CSRF protection behind a proxy, pass the original host through `X-Forwarded-Host` and configure `csrf({ origin })` explicitly when requests can originate from multiple trusted hosts.

+# Production Readiness
+
+This document tracks the work required before Tomoe should be called stable for production.
+
+## Current Status
+
+Tomoe is a release candidate. It has a real routing core, middleware pipeline, schema-validation relics, OpenAPI generation, a Node adapter, adapter edge coverage, and a repeatable Node soak harness. It still needs broader multi-runtime validation, release discipline, and external security review before a stable 1.0 label is credible.
+
+## Release Gates
+
+Tomoe should not publish a stable 1.0 release until these gates are complete:
+
+- CI passes on supported Node versions.
+- `pnpm test:bun` passes against the built package on Bun.
+- Node adapter behavior is tested for streaming request bodies, streaming response bodies, aborted uploads, repeated `Set-Cookie` headers, and `HEAD` fallback.
+- HEAD, OPTIONS, 404, and 405 behavior is covered.
+- Cookie, header, CSRF, and malformed URL behavior is covered.
+- Rate limiter memory behavior is covered.
+- `pnpm test:soak` passes on Node 22 for representative middleware, guards, JSON bodies, params, and nested `unite()` route chains.
+- Benchmark report includes Hono, Elysia, Fastify, Express, and Tomoe with exact versions.
+- Benchmark methodology includes repeated runs, raw output, and environment details.
+- Security policy is published.
+- Release notes and migration notes are published.
+- External security review is complete or explicitly deferred in release notes.
+
+## Runtime Support Matrix
+
+| Runtime | Status | Required Before Stable |
+| --- | --- | --- |
+| Bun | Primary target | CI smoke tests and benchmark runs |
+| Node.js | Supported through adapter | Adapter load tests, stream tests, graceful shutdown docs |
+| Cloudflare Workers | Intended | Worker smoke test and docs |
+| Deno | Intended | Deno smoke test and docs |
+| Vercel/serverless | Intended | Example deployment and cold-start notes |
+
+## Operational Checklist For Apps
+
+Applications using Tomoe in production should provide:
+
+- Reverse proxy body-size limits.
+- Request timeout and idle timeout settings.
+- Structured logging with sensitive header redaction.
+- Central error reporting.
+- Health and readiness endpoints.
+- Graceful shutdown for Node deployments.
+- Distributed rate limiting when multiple processes or regions are used.
+- Explicit CORS and CSRF policy.
+- Integration tests for every route contract.
+
+## Known Limitations
+
+- The built-in rate limiter is in-memory and per process.
+- The Node adapter converts Node streams to Web streams and should be measured on the target workload.
+- OpenAPI generation covers common schemas but is not a full replacement for dedicated schema-to-OpenAPI tooling.
+- Built-in middleware is intentionally small and does not replace application security policy.

+# Release Checklist
+
+Use this checklist for every release candidate and stable release.
+
+## Before Versioning
+
+- [ ] `pnpm install --frozen-lockfile`
+- [ ] `pnpm type-check`
+- [ ] `pnpm lint`
+- [ ] `pnpm test`
+- [ ] `pnpm test:bun`
+- [ ] `pnpm test:soak`
+- [ ] `pnpm build`
+- [ ] `pnpm audit --prod`
+- [ ] Benchmark report regenerated when performance claims change.
+- [ ] README performance section matches benchmark results.
+- [ ] `CHANGELOG.md` documents user-visible changes.
+- [ ] Migration notes are included for breaking changes.
+- [ ] Supported runtime matrix is updated.
+
+## Versioning
+
+- [ ] Package versions updated.
+- [ ] Git tag created.
+- [ ] GitHub release created with changelog.
+- [ ] npm package published with provenance when available.
+
+## After Release
+
+- [ ] Install the published package in a clean app.
+- [ ] Run Node smoke test.
+- [ ] Run Bun smoke test.
+- [ ] Verify package exports and type declarations.
+- [ ] Verify docs examples compile.
