Producer makes it real. Your application owns it.** Producer is the PHP realization layer for [Kumwe Studio](https://github.com/kumwe/studio), the schema-aware visual composition platform. Studio hands your application a canonical, portable JSON composition — never markup, never styles, never code. Producer is what turns that composition into reality on a PHP host: - **Wire handling** — parses and validates Studio's request envelopes, routes the closed operation set, and answers with strict canonical JSON and the stable twelve-category error taxonomy. - **Rendering** — turns a published composition into semantic, fully escaped HTML with working no-JavaScript fallbacks for the complete Studio block catalog. - **Stylesheets** — generates the static CSS a design's tokens and layout vocabulary imply; nothing is computed per request and nothing is inlined. - **Contract proof** — vendors the Studio corpus at one exact pinned release, digest-verifies it, and replays the published conformance vectors, so what this library claims is what it proves. Producer deliberately contains **no authority, no storage, no Node.js, and no render-time code generation** — your application keeps authentication, authorization, persistence, and templates, and implements Producer's small port interfaces with its own services. The full rules live in the [charter](CHARTER.md); the division of labour with Studio and with host applications is recorded in [`docs/host-agreement.md`](docs/host-agreement.md). The pipeline ------------ [](#the-pipeline) StageOwnerWhat happensDesign**Studio** (browser)An author composes typed, theme-bounded blocks; Studio emits canonical JSONWire**Producer**Envelope validated, operation routed, host answers through its own portsAuthority and storage**Your application**Authorization, revisions, audit, persistence — all yoursRealization**Producer**Published composition → semantic HTML + generated stylesheetDelivery**Your application**Embeds the render result in its own templates and serves Studio's prebuilt assetsHow it is built --------------- [](#how-it-is-built) The library is layered with one dependency direction — Canonical JSON, the schema-property profile, the error taxonomy, the wire layer, rendering, stylesheets — each proven by replaying the vendored Studio conformance corpora before the next layer consumes it. The [engineering standard](docs/engineering-standard.md) states the architecture, code, testing, and documentation rules in full: strict types, final classes, injected authority, centralized escaping, deterministic output, typed refusals with stable codes, and a suite that proves intended outcomes only — the conformance corpora are the spine, negative paths are first-class, and frivolous tests are forbidden. Producer is also written to be ported. The contract is language-neutral JSON, so a Python or TypeScript sibling implements the same corpora and claims conformance the same way; the [porting guide](docs/porting-guide.md) gives an implementer the order, the boundaries, and the subtleties, so a port needs this repository and nothing else. Status ------ [](#status) Founding stage. The contract is vendored from a pre-release Studio pin and the surface below is under active construction; nothing here is a supported release yet. See [`docs/roadmap.md`](docs/roadmap.md) for what exists, what is proven, and what is next. Requirements ------------ [](#requirements) PHP 8.1 or newer with `ext-json` and `ext-mbstring`. No runtime Composer dependencies. Development ----------- [](#development) ``` composer check # lint, contract digest verification, dependency-free test suite ``` ### Health Score 38 — LowBetter than 83% of packages Maintenance100 Actively maintained with recent releases Popularity8 Limited adoption so far Community6 Small or concentrated contributor base Maturity33 Early-stage or recently created project Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
