-A WordPress plugin framework published as five Composer packages under `ahegyes/`, PHP namespace `DeepWebSolutions\Framework\`, GPL-3.0-or-later. splitsh splits each `packages/<dir>/` to its read-only `wp-framework-<dir>` mirror on every push to `trunk`, and a `v*` tag to every mirror without `--force`; consumers install the mirrors through `vcs` repositories, not Packagist, and prefix them with php-scoper through wordpress-configs. The packages form a stack: core requires bootstrap and shared, settings requires core, and woocommerce requires settings, each requiring only the layer below it, while shared also installs alone; a plugin ships only the closure of the highest package it uses.

 1. **Gates and toggles.** `should_load()` is static, pure and total: no hooks, writes, notices, translation, user reads or construction. Read options with an explicit default. Detect companions by include-time constants, classes or functions, aware of network activation. Gates read no request-type facts, because `REST_REQUEST` is defined only on `parse_request` and `is_admin()` holds in admin-ajax requests; callbacks check the request type. A feature's toggle and settings UI live outside its gate; a gate mixing an environment check with a setting exposes the environment half as a static method.
 2. **Nodes and the container.** Node classes never extend, implement or `use` optional or late-loaded types. Never constructor-inject a gated component; inject ungated services. Every injected service that implements `ComponentInterface` is also a node, because only nodes run `register_hooks()`. Definitions are static closures, taking `ContainerInterface $c` only when they read the container, or autowiring, never PHP-DI helpers. Hold the built container as `ContainerInterface`. Container reads belong in the kernel and composition wiring: a class-entry read checks the entry's type before use, and a factory collecting contributors re-applies their `should_load()` before resolving them. Framework classes take their logger injected; the composition root chooses the logger. A failure is logged with its Throwable under `exception`, a `WP_Error`'s Throwable data included. The uninstall engine runs without a composition root, so it writes the jobs it could not unschedule to PHP's error log, one line per site.
 3. **Constructors and `register_hooks()`.** Constructors take services only. Plugins boot on `plugins_loaded` at priority 15, after `woocommerce_loaded`, Action Scheduler's priorities 0 and 1 and `woocommerce_blocks_loaded` have fired, so work that waits for them hooks `init` or later. `register_hooks()` adds `array( $this, 'method' )` hooks, or constructs an `OptionsPage`, `ProductDataTab` or `ObjectForm` and calls its `register_hooks()`. It never fires actions, applies the plugin's own filters or reads a registry filled through them, because nodes later in the walk have not registered yet. Registration-time hooks register unconditionally and authorize in the callback. Scheduled-hook callbacks register on every request, because Action Scheduler runs actions in admin-ajax, WP-Cron and WP-CLI requests, and tolerate a duplicate or a missing invocation.
-4. **Packages and `Shared\`.** Package edges stay as in the file map: a package requires only the layer below it, declaring a lower one only to raise its floor, and builds on everything beneath it, as woocommerce also builds on WooCommerce; a new edge needs the owner. Settings and WC helpers take data and a definition object, hosts take data, and neither implements a core type, because the kernel builds nodes by class-string. Every reachable `Shared\` symbol is API, and WordPress never enters the shared package. Shared holds kernel types that code without core can use; a primitive several packages need lives in the lowest of them, public only when it fills a gap that PHP, its extensions and PHPStan's typing leave, with its siblings decided together. A kernel type enters only when it would work unchanged in any PHP project, and on the owner's ruling. Result serves only an internal operation with two or more expected failure reasons a caller branches on, declared as `AbstractResult<T, E>` under `#[\NoDiscard]`; WordPress and WooCommerce APIs, filters, REST and AJAX responses and v1 public functions use `X|WP_Error`. Carriers are `final readonly`; one whose identity is its values extends `AbstractValueObject`, while a snapshot of stored data does not. `Version` parses only versions the plugin controls, never on the boot path. Framework code throws the `Shared\Exception` mirrors. A runtime check stays where a violation fails silently, can lose or expose data, or breaks a standard the class implements. A violation the platform tolerates harmlessly gets no runtime check, at most a PHPStan type.

A violation the platform tolerates harmlessly gets no runtime check, at most a PHPStan type.
 5. **Safeguards.** Everything a safeguard calls lives in `includes/safeguards.php` or files it requires. The entry loads that file before `load.php` and the floor gate, so a safeguard runs on any runtime that parses the plugin: it parses on PHP 7.4 and calls only WordPress APIs present at the oldest WordPress the bootstrap package runs on, which `phpstan.bootstrap.neon` sets, or guards them. Relaxation happens only through the safeguard's own filter, after `{prefix}/boot/succeeded`, on an explicit `false`.
 6. **Shared logic.** `src/` holds a plugin's composition root and its components. Code that registers no hooks and is not part of the tree, such as option keys and readers, the footprint, migration steps and asset registrars, is prefixed functions and constants in `includes/`, which `functions.php` loads. Per-request state lives in a static holder or `WC()->session`. No service locator.
 7. **Migration steps.** Append-only; a retired step keeps its code or throws. Converge from any partial state; verify writes and throw on failure, including a scheduler write that returns `WP_Error`. Role capabilities are granted by `Permission\CapabilityGrants`, never by a step. Create resources resumably (lookup marker, explicit `post_author`). Use WC CRUD for orders and products. A plain step finishes well under 10 minutes; bulk work is a `BatchedMigrationStepInterface` step, run only from the runner's scheduled hook, at about 1–2 s per batch. Steps run on `wp_loaded`, so every `init` registration exists. One linear list serves every build variant.
 8. **Settings.** Full keys are the plugin's prefixed option constants; WC ids are flat. Boot-time defaults are constants; translated defaults come from the plugin's text reader after `init`. Validate on write, and guard every typed read: `filter_var( $raw, FILTER_VALIDATE_*, FILTER_NULL_ON_FAILURE ) ?? $default`, or a strict `in_array()` for a choice. Direct meta writes go through `wp_slash()`. The framework detects a failed query only where it runs the query itself; a WordPress or Action Scheduler API's failure is accepted as the API reports it. The uninstall engine is the exception, because it keeps consent until a pass runs clean. Framework components store data only under the consumer's `{prefix}_`, so the plugin's footprint covers it; a `TransientCache` prefix and any generation option it names start with it, so the footprint covers the generation option, and its entries, transients that all carry a timeout, expire on their own. An `ObjectCache` group starts with it too, which keeps it apart from core's and other plugins' groups. The bootstrap updater's release caches carry the text domain instead and expire on their own. WooCommerce multiselect option keys are truthy, because WooCommerce's save drops `'0'` and `''`.
 9. **Object forms** render through `Forms::render_control()`, print their nonce bound to the object and verify it before they evaluate their definition; every framework saver goes through `Forms::sanitize_fields()` and leaves absent (unrendered or disabled) fields untouched, but for limitation 4's WooCommerce checkboxes and multiselects.
-10. **Translation, by-path files, Plugin Check.** Never translate at include or registration time. Framework strings use only the `'wp-framework'` domain, owned by core, settings and woocommerce; bootstrap and shared ship none, so a boot notice builds its translated message in its render callback and prints it through `Requirements::print_admin_notice()`. The bootstrap package stays 7.4-parseable, loaded by path, outside every `autoload` key, and defines code only as final classes with public static entry points; consumers require only its `load.php`, whose path is public API. Code is Plugin-Check-clean, using inline `phpcs:ignore` with a reason; local PHPCS runs the full `WordPress` standard, which covers the WordPress sniffs Plugin Check runs, and Plugin Check's own `PluginCheck` sniffs over the packages, which Plugin Check skips in a plugin's `vendor-prefixed/` (its file checks run only at release).

 ## Style
 
-- Every PHP file opens with `<?php declare( strict_types=1 );`. Every package directory holds the stub `index.php`, `<?php declare( strict_types=1 ); // Silence is golden.`, and every other file outside the shared package carries `\defined( 'ABSPATH' ) || exit;` after its `use` block. Code uses `array()`, `final` classes by default and `#[\Override]` on every override, and `protected` rather than `private`, except for the internals of a non-final class, which are `private` because its protected members are contract.

Every package directory holds the stub `index.php`, `<?php declare( strict_types=1 ); // Silence is golden.`, and every other file outside the shared package carries `\defined( 'ABSPATH' ) || exit;` after its `use` block, unqualified in a global file. Code uses `array()`, `final` classes by default and `#[\Override]` on every override, and `protected` rather than `private`, except for the internals of a non-final class, which are `private` because its protected members are contract.
 - No package ships free functions or a Composer `files` entry. A stateless function family is a final class with public static entry points, protected static helpers and a protected constructor. An operation that carries state across its steps is an object, and constant data is a constant. On a final class, a protected helper with a single call site is inlined, unless it is a `match` target, a hook callback or an override, or carries a `@phpstan-assert*` tag. Logic several classes share has one implementation: when its callers are in one package, an `@internal` final collaborator or an `@internal` public static on the class that owns the concept, and when they span packages, the smallest public API in the lowest package that needs it. A protected copy needs the owner's ruling. A lone call to a WordPress, WooCommerce or PHP API is not a copy, and neither is an idiom WPCS needs to see at each call site; the framework knowledge wrapped around such a call is. A copy also stays where no single home loads for every caller, as between PHP 7.4 by-path code and autoloaded code. The by-path classes register hooks with static closures, which bind each registration without static state, and a failed boot or boot check hooks its notice as a static closure; every other hook callback is a public named method. A framework method takes a callable only for consumer code it runs inside its own envelope, as the boot composition, migration steps and the uninstall cleanup, or for per-field logic in field arrays, and spells it `callable`; a helper's definition comes from a definition object, and an envelope inside the framework is written inline, with the rule it applies in one home.
 - A name imported from `Psr\` takes a `Psr` alias, as in `use Psr\Log\LoggerInterface as PsrLoggerInterface;`, so every use shows that the type is a PSR interface or class. Only PHP's own functions and constants take a leading `\`, which lets opcache compile the functions it special-cases; WordPress, WooCommerce and Action Scheduler functions and constants are unqualified, and classes are imported or fully qualified.
 - Every element outside `tests/` has a docblock: one third-person sentence naming the role, such as "Returns …", plus a second paragraph only for a non-obvious why. Property and constant docblocks open with "The …", constructors read "Constructor.", and an override reads `{@inheritDoc}`. Every other function and method docblock ends with `@return`, `@return  void` included. Tag values align at column 10, a file docblock's `@package` sits in its own group after `@since` and `@version`, a function or method that declares a `global` documents it with `@global` in its own group between `@version` and `@param`, each `@param` stays on one line, `@throws` reads "Thrown when …", `@since` names the release that added the element, and `@version` the last release that changed its behavior or signature.

 ## Limitations
 
-1. A throw in `register_hooks()` leaves earlier hooks live, and side effects are never undone. Safeguards still ignore relaxations, because `{prefix}/boot/succeeded` never fires. Gates evaluate once, at `plugins_loaded`. Schema-gated components switch on one request after the migrating request. The request that activates the plugin does not boot it, because WordPress includes the plugin's file after `plugins_loaded`, so its post types and endpoints first register on the next request.

The request that activates the plugin does not boot it, because WordPress includes the plugin's file after `plugins_loaded`, so its post types and endpoints first register on the next request.
 2. A request killed mid-migration holds the lock until 10 minutes after the step or batch it was running began, then the step re-runs and the error row names the step that did not finish. One primary database is assumed. While a plain step's failure persists in production, each request issues one `INSERT IGNORE` plus one `SELECT`, one more `SELECT` until a first step succeeds, and admin screens read the error row; in local and development environments the lock is released, so every request re-runs the failing step. While a batched step is pending, a request outside the runner's hook takes no lock and only looks the hook up in the scheduler, and while its failure persists, each queue run fires the runner's hook to no effect and the failure is logged every 10 minutes. A WP-CLI process is one request, so once it has spent the runner's time budget, a long `wp action-scheduler run` stops running the migration, and the next request or process continues it. After a rollback, older code runs on newer data until the plugin is upgraded again; the written-back revision then re-runs the newer steps, and `{option}_high_water` keeps the highest revision reached. Mixed-version rolling deploys may re-run steps, which converge.
-3. Uninstall visits every site of a network and cleans each one that consents. The engine needs the plugin's PHP and WordPress floors, so where a site fell below them a web request deletes the plugin's files and leaves its data and cron events until the plugin is installed and deleted again on a compliant runtime, while WP-CLI fails and keeps the files. A throw from another plugin's hook ends that site's pass, and the rest of its footprint and its consent row wait for the next uninstall. A web request on a large network refuses and names `wp plugin uninstall`; on a network of thousands of sites, or on a single site whose footprint holds many rows, a web request can still exceed the server's time limit, and a retry or `wp plugin uninstall` completes it. Where the object cache cannot flush its runtime cache, every visited site's options stay in memory until the request ends. Network options and network-global user meta go only on a single site or on the consent constant. Exact `options`, `transients` and `network_options` names match under the database collation, as WordPress's option API matches them. An `option_prefixes` or `user_meta_global_prefixes` entry that the table prefix starts with, such as `wp_` on a default install, also deletes the site's roles and every user's capabilities, which WordPress names after the table prefix; WordPress reserves `wp_` for itself. On an installation of several networks, the large-network bound counts the current network's sites, and the network pass deletes every network's options but clears only the current network's cached values. Action Scheduler actions stay queued when it is not loaded at uninstall, and fail once it runs them, since no callback is registered; on a site without its tables, unscheduling logs a database error and does nothing else; a job that cannot be unscheduled is logged and left.

 4. Over WC REST, `validate` receives WooCommerce's normalized value: unknown multiselect choices are already dropped and text already sanitized. A rejected value is not stored, but the response echoes it. Grouped `option[key]` ids would bypass the bridge, hence flat ids. WC REST lists only WooCommerce's own field types, so custom-type and `checkboxes` fields are not reachable there. A product field's `validate` runs only on the classic product edit form; WC REST `meta_data`, CSV import and CRUD writes store what they are given. An object form field's `validate` runs only on its form; REST, imports, meta and order CRUD writes store what they are given, and so does a Custom Fields box for a key without a leading underscore: core's on a post type that supports `custom-fields`, orders in the posts table included, and WooCommerce's on the order tables' edit screen. WC-rendered controls carry WooCommerce's markup, and the row printed around a custom-type or `checkboxes` field on a WooCommerce settings screen or the product data panel imitates it. On a WooCommerce settings screen a field's `render` callable needs a type WooCommerce does not draw: on one of its own types WooCommerce draws its control and the callable never runs. The framework guarantees markup only for `Forms::render_control()`. `OptionsPage` and `ProductDataTab` report a rejected field in the page's notices, not beside the field, which after the redirect shows its stored value rather than the rejected input. `ObjectForm` reports it as a one-shot user notice through the plugin's `AdminNotices`, shown in the post editor after the save, or else on the user's next admin screen of the site it was saved on, the network and user admin counting as the main site's; a newer rejection of the same field, on any object, replaces it, and a rejection whose notice fails to save goes unreported. On the profile and in the block editor, which never validate the form, a number the browser cannot parse posts as empty and clears the stored value. With WooCommerce's beta `settings-ui` feature on, the sections a framework tab defines stay classic, and a framework section registered on any tab renders in its Settings UI, which saves through the same form post. A field the Settings UI's schema refuses, such as a `checkboxes` or custom-type field holding an array or a radio listing disabled choices, renders that section classic, with a `_doing_it_wrong` notice under `WP_DEBUG`; a field it has no control for, such as one of those types holding no array or WooCommerce's `color`, makes the page fail to render and offer WooCommerce's "Use classic settings" link, under which every field saves. On a WooCommerce settings screen a cleared checkbox or multiselect posts nothing, so one the section does not render at save is stored cleared.
 5. Partial bootstrap package: if `load.php` exists but a file it requires is missing, the `Error` is thrown before the template's catch and the plugin fatals at include; its uninstall shim catches it, except on PHP 7.4, where a failed `require` is fatal. A missing `vendor-prefixed/` unregisters the updater. Core and woocommerce print their boot and migration notices through bootstrap's `Requirements`, so a plugin that boots them without requiring `load.php` fatals when one of those notices renders. Update offers come only from WordPress's own plugin update check. While its wordpress.org request fails, the check offers no Update URI release, so a new release waits for a later check that succeeds. A plugin active only on sites other than the main one is never offered a release, because WordPress checks only on the main site and in the network admin.
 6. Deactivation and recovery mode unload safeguards, as for any plugin. Plugins whose data would leak (IC) hide it at the data level.
-7. Scheduling and one-shot notices are best effort. Either scheduler can run an invocation twice or not at all, and work advances only with site traffic, Action Scheduler's admin dispatch, or a system cron or WP-CLI runner. On hosts that replace WP-Cron's store, the WP-Cron backend still reads only the `cron` option, so it may not see the host's events. Action Scheduler compares hook names and arguments under the database collation, so identities that differ only in letter case are one there. Action Scheduler stores a string argument holding invalid UTF-8 with those bytes replaced, which its callbacks then receive, while WP-Cron's write of it fails, because WordPress refuses invalid UTF-8 in the options table. Two concurrent renders can both show a one-shot notice, a request that dies after output shows it again, and a block-editor delivery whose response the editor never receives, as when the user leaves during it, loses its one-shots. Block-editor screens hide classic notices: the post editor fetches the site, network and user one-shots that name no screens as it loads and after each save that is not an autosave, while persistent and screen-limited notices wait for a classic screen, as every notice does on the other block editors. The post editor shows a notice's markup through core/notices' `__unstableHTML` option, which a WordPress release may change or remove. A dismissal, or a one-shot's showing, applies to the notice's id rather than to the copy the page showed, so a notice saved again under that id after the page showed it is deleted or hidden too. Two writes to one scope's notices, or to one viewer's dismissals, at the same moment can lose one of them: a notice added then never shows, a dismissal is undone, or a consumed one-shot shows once more. A notice whose write fails is lost, and logged only when the write throws.

The post editor shows a notice's markup through core/notices' `__unstableHTML` option, which a WordPress release may change or remove. It reads each notice aloud through `wp.a11y.speak()`, which drops text between angle brackets, so a literal angle-bracketed placeholder in a message goes unspoken. A dismissal, or a one-shot's showing, applies to the notice's id rather than to the copy the page showed, so a notice saved again under that id after the page showed it is deleted or hidden too. Two writes to one scope's notices, or to one viewer's dismissals, at the same moment can lose one of them: a notice added then never shows, a dismissal is undone, or a consumed one-shot shows once more. A notice whose write fails is lost, and logged only when the write throws.
 8. Capability grants act on `wp_loaded` after the declaration changes or a declared role appears or is deleted, and the current user sees a grant or revocation from the next request. A granted capability removed or denied by hand stays so; a declared role deleted and created again is granted again, unless it was deleted while the plugin was inactive, which then reads as a hand removal. WP_Roles writes the whole roles row from the request's copy, so another request's role write in between is lost. A change the row does not keep is logged and made again on every request, which never ends on a site whose roles are defined in code (`$wp_user_roles`) or locked.
 9. `TransientCache` and `ObjectCache` are best effort. On the options table a value holding invalid UTF-8 is refused and `set()` returns false, and a `delete()` whose database write fails still returns true, so later requests read the entry until it expires or is set again. `getMultiple()` returns a decimal-string key as an integer, as PHP arrays do. `clear()` leaves earlier entries in place until they expire or the object cache evicts them, and behind a multi-node object cache that is not coherent, a node may read the old generation or salt until the new one reaches it. Without a persistent object cache, `ObjectCache` entries last one request, and an entry outlives its TTL until the request ends; some Memcached drop-ins keep a TTL over 30 days until eviction. Concurrent misses all recompute; nothing locks a key.
 10. The framework's queries name tables through `%i`, so a `wpdb` replacement whose `prepare()` predates WordPress 6.2 breaks them. A `Lock` lives in the current site's options table, and a hold is judged by the TTL its holder wrote. A holder learns of a takeover only at its next `refresh()`, so data the lock protects is written with a compare-and-swap, such as `OptionRows::replace()`, where a stale write matters.

+## Changelog entries
+
+Each user-visible change adds one fragment, so pull requests never conflict on `CHANGELOG.md`:
+
+```sh
+composer changelog:add
+```
+
+The command asks for the change's significance, its type and its entry, and writes the fragment to `changelog/<branch-name>`, which the pull request commits. CI validates the fragments with `composer changelog:validate`.
+
 ## Filing changes
 
 - Keep one concern per pull request.
 - Fill in the template's breaking-changes section.
 - Follow the code, documentation and commit conventions in [AGENTS.md](AGENTS.md).
+
+## Releases
+
+The five packages release together under one version. A release writes the fragments into a new version block of `CHANGELOG.md`, whose version the fragments' significance sets:
+
+```sh
+composer changelog:write
+```
+
+Pushing the tag `v<version>` on that commit splits it to every mirror, where consumers' `vcs` repositories find the release.
+
+## WooCommerce floor
+
+The woocommerce package tracks the newest stable WooCommerce release until a tag. Raising the floor moves, in one commit, the manifest's `extra.requires-wc`, the root's and the fixtures' `wp-plugin/woocommerce` and `php-stubs/woocommerce-stubs` constraints, the fixtures' `WC requires at least` and `WC tested up to` headers, and the locks. The same commit re-checks that WooCommerce still uses each cache group `MetaTypes::DEFINITIONS` names, because the uninstall engine flushes them.
