CoherynUI — Stable 1.0 Release Readiness Report
Date: October 27, 2026
Document ID: COH-REL-1.0-READY
Status: All Acceptance Gates Green
1. Executive Summary
All five mandatory advanced subsystems and the core Rust-native compiler have been implemented, tested, and verified under the canonical CoherynUI product identity and coherynui native CLI binary. Zero mandatory subsystems are deferred.
2. Mandatory Stable 1.0 Quality Gates
| Quality Gate | Acceptance Criteria | Subsystems & Evidence | Status |
|---|---|---|---|
| Gate 1: Correctness | Deterministic cascade layer generation, clean build ≡ cached build | @layer hierarchy verified in first_acceptance_test.rs and cache_equivalence_test.rs. | ✅ PASSED |
| Gate 2: Accessibility | WAI-ARIA 1.2 / WCAG 2.2 AA interaction patterns, focus trap, roving tabindex | accessibility-contracts.md and accessibility_primitives.test.ts. | ✅ PASSED |
| Gate 3: Browser Fallback | 3-tier cascade for optical effects (WebGPU → WebGL2 → CSS Glass → Opaque) | Verified in refraction_pipeline.test.ts and browsers.md. | ✅ PASSED |
| Gate 4: Security | Zero ambient authority in WASM plugins, fuel instruction metering, memory caps | Verified in security_sandbox_test.rs and capabilities-and-security.md. | ✅ PASSED |
| Gate 5: Optimization | Aggressive class renaming preserves DOM, SSR parity, and fail-closed dynamic safety | Verified in class_renaming_test.rs and conformance_benchmark_test.rs. | ✅ PASSED |
| Gate 6: Performance | Analytical spring solver with zero frame-rate jitter; sub-50ms cold compiles | Verified in spring_solver.test.ts and conformance_benchmark_test.rs. | ✅ PASSED |
| Gate 7: Distribution | Rust Edition 2024 Cargo Resolver 3 workspace, dual MIT/Apache-2.0 licensing | Configured in Cargo.toml, .github/workflows/ci.yml, LICENSE-MIT, LICENSE-APACHE. | ✅ PASSED |
3. Subsystem Release Verification Matrix
- CoherynUI CSS Engine & Native CLI (
coherynui):- Full canonical utility registry with display, flexbox, alignment, grid, typography, sizing, spacing, positioning, borders, shadows, opacity, and transitions.
- Arbitrary value brackets (
p-[27px],w-[calc(100%_-_2rem)],bg-[#172033]). - Container Queries (
cq-root,cq:,cq-sm:,cq-md:,cq-lg:). - Adaptive Layout Primitives (
stack,cluster,grid-auto,center,sidebar,flow,cover,switcher).
- CoherynUI Components:
- 8 component families, 48 patterns (@coheryn/coherynui-components, @coheryn/coherynui-react).
- Focus trapping, roving tabindex, escape dismissal, and scroll lock.
- CoherynUI Motion:
- Analytical harmonic oscillator spring physics ($m \cdot x'' + c \cdot x' + k \cdot x = 0$) (@coheryn/coherynui-motion).
- Interruptible retargeting without velocity snaps, sequential timelines, FLIP layout transitions.
- CoherynUI GPU Materials:
- Real WGSL optical refraction shader (shaders/wgsl/refraction.wgsl).
- Normal mapping, chromatic dispersion, pointer ripple disturbance, 3-tier fallback.
- CoherynUI Class Optimizer:
- Whole-project AST rewriter across markup and CSS (crates/coherynui-class-opt).
- Bidirectional manifest generation (
coherynui.manifest.json), reserved word shielding, fail-closed dynamic checking.
- CoherynUI Plugin Host:
- Sandboxed WebAssembly Component Model runtime (crates/coherynui-plugin-host).
- Versioned WIT ABI (plugins/wit/coherynui.wit), instruction fuel metering, memory limits, zero ambient authority.
