ARCHITECTURE.md and ARCHITECTURE_RU.md (620 lines each) were a parallel
documentation source that drifted from the code and contained outdated
references (CONTEXT_* string constants, global $db, MIGRATION.md which
does not exist).
All relevant content is now covered by specialized pages in docs/:
- Module system → development/modules.md
- Bootstrap contexts → development/bootstrap-contexts.md
- Event system → development/event-system.md
- Build variants → builds/build_system.md
docs/{en,ru}/development/architecture.md rewritten as a clean, self-contained
overview: source tree table, runtime flow diagram, extension points table,
contributor rules. Broken links to ARCHITECTURE.md and MIGRATION.md removed.

# Architecture Overview
|
|
|
|
## Project type
|
|
|
|
Structured PHP monolith with a modular extension layer.
|
|
|
|
- No DDD, no Hexagonal, no Clean Architecture — intentional.
|
|
- Split by context with minimal abstractions: `Controller → Service → Repository`.
|
|
- Two build artifacts from one codebase: **MAIN** (full panel) and **LB** (load balancer subset).
|
|

## Source tree
|
|
|
|
| Path | Role |
|
|
| ---- | ---- |
|
|
| `src/core/` | Infrastructure primitives: DI container, events, HTTP, config, auth, logging |
|
|
| `src/domain/` | Business contexts: Stream, VOD, Line, User, Server, Security, etc. |
|
|
| `src/modules/` | Optional extension layer — loaded by `ModuleLoader` |
|
|
| `src/public/` | Front controller, router, controllers, views, assets |
|
|
| `src/cli/` | Console commands and cron entry points |
|
|
| `src/ministra/` | Stalker Portal — isolated subsystem (`BoundaryInterface`) |
|
|
|
|

|
|
|
|
## Runtime model
|
|
|
|
Dependencies flow inward — modules may use core and domain, never the reverse.
|
|
|
|
```
|
|
public/index.php
|
|
└── XC_Bootstrap::boot(BootContext::ADMIN)
|
|
└── ServiceContainer (DI)
|
|
├── EventDispatcher (PSR-14)
|
|
├── ModuleLoader → loadAll() → bootAll()
|
|
└── Router → dispatch()
|
|
```
|
|
|
|
Domain classes receive the database via `setDb()` injection (called from
|
|
`bootstrap.php::wireDomainDatabase()`). No `global $db` in the web request path.
|
|
|
|

|
|
|
|
## Module system
|
|
|
|
Modules are isolated directories under `src/modules/` with a `module.json` manifest
|
|
and a class extending `BaseModule`. See [Module System](modules.md) for the full reference.
|
|
|
|
```
|
|
src/modules/my-module/
|
|
├── module.json # metadata
|
|
├── MyModuleModule.php # extends BaseModule, namespace XcVm\Module\MyModule
|
|
└── ...
|
|
```
|
|
|
|
---
|
|
|
|
## Bootstrap contexts
|
|
|
|
Four contexts control which subsystems initialize. See [Bootstrap Contexts](bootstrap-contexts.md).
|
|
|
|
| Context | Used for |
|
|
| ------- | -------- |
|
|
| `BootContext::MINIMAL` | Scripts needing only paths/config |
|
|
| `BootContext::CLI` | Cron jobs and CLI commands |
|
|
| `BootContext::STREAM` | Streaming endpoints |
|
|
| `BootContext::ADMIN` | Admin/reseller panel |
|
|
|
|
---
|
|
|
|
## Build variants (MAIN vs LB)
|
|
|
|
| | MAIN | LB |
|
|
| --- | ---- | -- |
|
|
| Admin panel | ✅ | ❌ |
|
|
| Streaming | ✅ | ✅ |
|
|
| Module system | ✅ | subset |
|
|
|
|
Controlled by `ServerEnvironment` enum and `module.json` `environment` field (`main` / `lb` / `any`).
|
|

|
## Key extension points
|
|
|
|
| Mechanism | How to use |
|
|
| --------- | ---------- |
|
|
| PSR-14 events | `EventDispatcher::listen()` or `#[ListensTo]` attribute |
|
|
| Service decoration | `$container->decorate('id', callable, priority)` |
|
|
| Stream middleware | Implement `StreamMiddlewareProviderInterface` |
|
|
| Cron entries | Override `getCronEntries()` in module class |
|
|
| DB migrations | Implement `MigratableInterface::getMigrations()` |
|
|
|

## Contributor rules
|
|
|
|
1. Modules must not modify core files.
|
|
2. No `eval`, monkey patching, or runtime file replacement.
|
|
3. Any module can be disabled via `config/modules.php` without touching core.
|
|
4. Protected services (`db`, `settings`, `config`, `auth`) cannot be decorated.
|
|
5. Keep EN and RU docs in sync in the same commit.
