core.backend Roadmap

By Olivier Mironescu Added: 2026-06-17 Updated: 2026-07-17

Living task list for core.backend — the Composer SDK that applications install to talk to the UNVRSL platform.

Current State (audit 2026-07-17)

Built:

DocumentShell (htmlTemplateInit) — config-driven HTML document shell with automatic core.assets injection (standards, ui, layouts css + ui.js)

Stubbed (empty files):

Not started:

API client (the SDK's core purpose): no Client class, no request signing, no service wrappers

→ Full code inventory: core.backend Code Reference

Depends On	For

core.console	API gateway endpoint, key validation scheme (request signing target)
core.assets	Stylesheet/JS URLs injected by DocumentShell; User Circle script
core.auth	Session/token formats the SDK must validate
core.storage	First service wrapper target (browser-upload L2 flow)
Plesk	Composer path registration per domain (install mechanics)

[ ] Client foundation — UNVRSL\Core\Client: api_key + base_url config, curl transport, JSON envelope handling, timeout/retry

[ ] Typed errors — AuthError, QuotaExceeded, NotFound, ValidationError, ServerError (no silent arrays)

[ ] Storage wrapper (first service) — $client->storage(): pools, objects, upload (single + transparent multipart with parallel parts per browser-upload L2), download, delete

[ ] ai: conversations, messages, SSE streaming reader (curl CURLOPT_WRITEFUNCTION, no framework)

[ ] datetime-parsers.php — implement: ISO 8601 ⇄ MySQL datetime, timezone helpers (UTC storage ⇄ user-local display), duration/relative formatting

[ ] bootstrap/init.php — decide purpose (env loader? error handler? constants?) or remove from autoload if unused

[ ] DocumentShell: User Circle injection toggle (auto-inject core.assets user-circle.js when a session cookie is present)
