## Descripció

**ALTOS** speeds up the WordPress admin by giving you per-screen control over which
active plugins are actually loaded. Most WordPress sites accumulate dozens of plugins
over time, but only a few are needed on any given admin screen. Loading them all
on every page wastes memory, time, and database queries.

ALTOS operates at the WordPress core level via the MU-plugins mechanism, intercepting
the loading pipeline before WordPress fully initialises. It cleanly skips heavy 
code paths on screens where they aren’t needed — while preserving admin menus, dependency
relationships, and safety guards.

**Key features**

 * **Per-screen control** — Set rules for each admin screen (Dashboard, Posts, Pages,
   Settings, WooCommerce, Custom Post Types, …).
 * **Three states per rule** — Enabled (always load), Disabled (never load), Defer(
   load after the main page).
 * **Smart menu preservation** — Admin menu entries stay accessible for blocked/
   deferred items via an automatic snapshot system.
 * **Hierarchical rules** — Global  group  screen, with intelligent inheritance.
 * **Automatic mode with suggestions** — Confidence-scored recommendations from 
   real performance samples; you review and apply manually.
 * **Dependency cascade detection** — Catches dependent items when a parent is blocked.
 * **Request-type optimisation** — Separate rules for AJAX, REST API, WP-Cron, and
   WP-CLI.
 * **Update Optimizer** — Three strategies to reduce update-check overhead without
   breaking badge counts.
 * **Per-plugin performance metrics** — Real-time load time, DB queries, memory.
 * **Developer tools** — Admin drawer, admin-bar integration, REST endpoints, extensive
   filters/actions.
 * **Built-in translations** — Czech, Slovak, Polish, German, French, Spanish.

**Typical impact**

 * 30–50 % faster admin pages.
 * 20–40 fewer database queries per admin page.
 * 1–5 MB less memory per blocked item.

**Safety by default**

 * Manual mode requires explicit rules — nothing is changed without your action.
 * Automatic mode only _suggests_ — never applies on its own.
 * The loader protects itself from being blocked.
 * Page-builder bypass for Elementor, Bricks, Divi, Beaver Builder during active
   editing sessions.
 * Emergency recovery URL for one-click bypass if a misconfiguration breaks the 
   admin.

### External Services

This plugin does not contact any external services. It does not send analytics, 
telemetry, license checks, or any other network requests. All rules, samples, snapshots,
and configuration are stored exclusively in your own WordPress database.

The «Update Optimizer» feature exclusively _throttles_ the standard WordPress update-
check HTTP requests to `api.wordpress.org` — it never adds new endpoints and never
sends additional data.

### Privacy

ALTOS stores all of its data in your own WordPress installation:

 * Rules and configuration are stored in the WordPress options table.
 * Performance sampling data is stored in a plugin-owned custom table (`{prefix}
   sapm_sampling_data`) with 30-day retention.
 * No personal data about visitors or administrators is collected.

The plugin does not transmit any data to external services and does not contact 
any external endpoints other than throttling WordPress’s existing `api.wordpress.
org` update checks when the (opt-in) Update Optimizer is enabled.

## Instal·lació

 1. Install via **Plugins  Add new  Upload Plugin** in WordPress, or upload the unzipped
    folder to `/wp-content/plugins/altos/`.
 2. Activate the plugin through the **Plugins** screen in WordPress.
 3. On activation, the plugin automatically writes a small MU-loader file to `wp-content/
    mu-plugins/altos.php`. This is what allows per-screen filtering to run before WordPress
    loads the regular plugins. The file is removed automatically on deactivation.
 4. Go to **Settings  Plugin Manager** in your WordPress admin.
 5. Configure rules manually, or enable **Automatic mode** to get data-driven suggestions
    after a day or two of sampling.

**Requirements**

 * PHP 7.4 or newer (PHP 8.0+ recommended).
 * WordPress 6.0 or newer.
 * Write permission for `wp-content/mu-plugins/` (almost all hosts allow this; some
   managed-WordPress hosts restrict it).

## PMF

### How does this differ from «deactivating» a plugin?

ALTOS runs **before** WordPress loads regular plugins, using the MU-plugins mechanism.
That means the code is genuinely _not loaded_ on screens where you don’t need it—
not loaded-and-then-suppressed. Deactivation is global and permanent; this lets 
you keep an item active site-wide while skipping it on specific admin screens or
request types.

### How does Automatic mode work?

For 24–48 hours after you enable it, the loader samples real performance data on
your own admin: load time, database queries, memory per active item, per admin screen.
It then analyses those samples to suggest rules with a confidence score (0–100 %)
and estimated savings. **Suggestions are never applied automatically** — you review
them and apply with one click.

### Is it safe to block items?

ALTOS has multiple safeguards:

 * Dependency cascade detection — if you block a parent (e.g. WooCommerce), dependents
   are flagged automatically.
 * Smart menu preservation keeps blocked items’ admin menu entries reachable.
 * Critical scenarios (page-builder editing, WooCommerce checkout/cart) are auto-
   excluded.
 * The loader itself is auto-protected from being blocked.

Recommendation: enable Automatic mode on a staging site first, review the suggestions,
then export to production.

### Does this work with page builders?

Yes. Elementor, Bricks, Divi, and Beaver Builder edit sessions are detected and 
the loader steps out of the way to avoid breaking editor previews.

### What about WooCommerce?

Full WooCommerce support: cart, checkout and account pages are excluded from any
blocking on the frontend. Admin screens are recognised per area (products, orders,
settings, …) so you can keep WooCommerce active on its own screens while skipping
it elsewhere.

### Does it affect the frontend?

The Frontend Optimizer is an opt-in feature. If you leave it disabled (default),
the frontend is completely unaffected. With it enabled, you can selectively skip
items per page-type context (homepage, single, archive, …).

### How does the Update Optimizer work?

Three strategies are available:

 1. **TTL extension** — Throttle the outbound `api.wordpress.org` update HTTP calls
    so they only re-run after a configurable interval (12 h  24–72 h). WordPress keeps
    its own cache; we only reduce how often it gets refreshed.
 2. **Page-specific** — Only run update checks on the dedicated **Plugins**, **Themes**
    and **Updates** admin pages.
 3. **Cron-only** — Move all update checks to background WP-Cron; the admin never blocks
    on them.

All strategies preserve update badge counts and «Check now» buttons still work as
expected.

### Can I use it on multisite?

Yes. Network activation is supported but each subsite needs its own per-site rules.
The MU-loader is created once for the network.

### Does the plugin contact any external servers?

No. See the **External Services** section above.

### What languages is the plugin translated into?

English (source) plus Czech (cs_CZ), Slovak (sk_SK), Polish (pl_PL), German (de_DE),
French (fr_FR), and Spanish (es_ES). Translations live in `/languages/` as `.po`/`.
mo`. Community translations from `translate.wordpress.org` are also picked up automatically.

## Registre de canvis

#### 1.3.9 — 2026-06-10

 * **UPDATED** Tested with WordPress 7.0.

#### 1.3.8 — 2026-05-18

 * **NEW** Explicit user consent flow for the MU-loader install. After activation,
   an admin notice asks whether to install the small loader file in `wp-content/
   mu-plugins/`. Without consent the plugin runs in limited mode (filtering still
   works for later option queries; only the very first plugin-load pass is unaffected).
 * **CHANGED** No more silent self-healing of the MU-loader file. The file is created
   only on explicit click of «Install loader file» in the admin notice, and removed
   automatically on deactivation.
 * **FIXED** Plugin URI header now points to the WordPress.org plugin directory.
 * **FIXED** Two inline `<script>` blocks in the settings page extracted to a dedicated`
   assets/admin-handlers.js` enqueued via `wp_enqueue_script`. The frontend bar’s
   JSON payload now goes through `wp_add_inline_script()` instead of an inline `
   <script>` tag.
 * **FIXED** All `$_POST` / `$_GET` / `$_SERVER` super-global reads now use `wp_unslash()`
   plus an explicit `sanitize_*()` helper. `$_SERVER[REQUEST_TIME_FLOAT]` is cast
   through `(float)` before arithmetic. `$_SERVER[REQUEST_URI]` goes through `sanitize_text_field(
   wp_unslash( … ) )`.
 * **FIXED** All `json_decode()` results from POST payloads are now deep-sanitised
   by a new recursive `sanitize_rules_array()` helper before being persisted. `stripslashes()`
   replaced with `wp_unslash()` where applicable.
 * **IMPROVED** All uses of `WP_PLUGIN_DIR` / `WP_CONTENT_DIR` annotated with explanatory
   comments documenting why the WordPress-provided constants are the correct API
   here (no `__FILE__`-relative helper exists for resolving other plugins’ base 
   paths or the must-use plugins folder at the MU-loader load stage).

#### 1.3.7 — 2026-05-15

 * **NEW** Internationalisation: ships with full Czech, Slovak, Polish, German, 
   French, and Spanish translations.
 * **NEW** Per-language `.pot`, `.po`, and `.mo` files in `/languages/`. Domain 
   Path header added.
 * **CHANGED** Plugin renamed to «ALTOS» with slug `altos` for the WordPress.org
   directory.
 * **CHANGED** Self-hosted GitHub updater removed — WordPress.org handles updates
   from now on.
 * **CHANGED** Update Optimizer refactored to throttle HTTP requests only; it no
   longer hooks the update transients (cleaner separation from WordPress’s own updater).
 * **FIXED** Two stray non-English strings replaced with translatable English source
   strings.
 * **FIXED** Hardened output escaping across the admin UI (`_e()`  `esc_html_e()`
   etc.).
 * **FIXED** Replaced `parse_url()`, `unlink()`, `date()` and `mt_rand()` with their
   WordPress-recommended counterparts.
 * **IMPROVED** All input super-globals now go through `wp_unslash()` + `sanitize_*`.
 * **IMPROVED** Stricter `phpcs:ignore` documentation on the plugin’s own database
   queries (custom `sampling_data` table).

#### 1.3.5

 * **FIXED** MU-loader self-healing — recreates a missing MU file on `admin_init`
   to prevent permanent loss after a failed activation.
 * **FIXED** Early translation loading warning on WP 6.7+ (`_load_textdomain_just_in_time`
   notice).
 * **IMPROVED** MU-plugin directory resolution consistently respects the `WPMU_PLUGIN_DIR`
   constant.

#### 1.3.2

 * **FIXED** Self-protection in filtering: the loader can no longer block itself.
 * **FIXED** Invalid frontend rule modes safely fall back to passthrough.
 * **IMPROVED** Lower overhead in frontend/cache and auto-rules paths.

#### 1.3.0

 * **NEW** SHA256 package integrity validation before install.
 * **IMPROVED** Frontend drawer uses a shared drawer CSS with unified visual style.
 * **IMPROVED** Frontend bar JavaScript refactor (Shadow DOM mount, per-page override
   UX, reset flow).
 * **IMPROVED** Update metadata caching strategy (lock + fallback + HTTP validators).

#### 1.2.0

 * **NEW** Automatic mode with confidence-scored suggestions.
 * **NEW** Custom table for sampling data, 30-day retention.
 * **NEW** Update Optimizer (TTL extension / Page-specific / Cron-only).
 * **NEW** Dependency cascade detection.
 * **NEW** Request-type rules (AJAX, REST API, WP-Cron, WP-CLI).
 * **NEW** Per-plugin performance metrics.
 * **NEW** Admin drawer overlay.
 * **IMPROVED** Hierarchical rule system with global / group / screen levels.
 * **IMPROVED** Smart menu preservation system.
 * **IMPROVED** WooCommerce integration.
 * **IMPROVED** REST API endpoints for programmatic control.

#### 1.1.0

 * **NEW** Per-screen control system.
 * **NEW** Defer-loading support.
 * **NEW** Admin drawer interface.
 * **NEW** Performance monitoring dashboard.

#### 1.0.0

 * Initial release.
