11. Docs improvements. Say each thing once, in the file whose subject it is by nikolaystrikhar · Pull Request #87 · stellarwp/plugin-absorber

nikolaystrikhar · 2026-08-25T11:24:05Z

What: comments across all 30 files in src/, and the prose in README.md and all seven docs/ files — no executable code, no headings, no links, no code examples.

Honestly it's just AI simplifies AI comments, so I'd just merge lol. I think we have too much everywhrre for nothing.

Usage: what a reader stops having to scroll past.

// Before -- 5 lines, in Loader::load_all()
// The flush is where a duplicate slug is caught, and reading the registrar is where a
// missing container or an unusable binding is. All three are bootstrap mistakes, and all
// three arrive inside plugins_loaded: letting one out would fatal every request, front end
// and admin alike, and lock the developer out of the screen where the registration could be
// corrected. The hook this runs on exists to prevent a fatal, so it is the last place that
// may cause one -- the mistake is reported to the developer and the load is abandoned.

// After -- the half the code cannot say
// A duplicate slug is only caught here, inside the hook that exists to prevent a fatal --
// so it is the last place allowed to cause one.

Why this way:

The rationale was written twice, and AGENTS.md is the copy that is meant to last. Boot/Scheduler shared 52 near-verbatim phrases with it, Provider 35, Loader 25. Within src/ the same arguments repeated again — the reader-drains-the-buffer note in four files, the hook-prefix stand-down in three. Each has one home now and a clause everywhere else. Prose in src/: 14,876 words to 6,873.

The docs restated each other rather than linking. recipes.md carried conflict-handling.md's policy-precondition sentence at 93% overlap, and configuration.md's activation-record semantics again. The how-to file now points at the reference file, using links that were already in the text. 8,084 words to 6,047.

filters.md and the README keep their length. Both are already dense — a filter table and an overview that exists to link out. Trimming to hit a number would have cost facts, so they got 3% and 4%.

Comments only, proved rather than asserted. Every changed src/ file is token-identical to its base outside comments, checked with token_get_all(); every @param, @return, @var and @throws survives with its type, which level 9 reads. Every markdown heading and link is byte-identical, so the anchors sibling docs target still resolve. PHPStan level 9 clean, 610 tests green on singlesite and multisite.

Summary by CodeRabbit

Documentation
- Clarified setup, multisite behavior, hook timing, activation, conflict handling, redirects, notices, filtering, and plugin loading.
- Expanded guidance for validation errors, callable configuration, capability checks, network activation, deactivation, and bundled-file handling.
- Refined inline documentation to explain runtime behavior, responsibilities, and edge cases.
Bug Fixes
- Improved diagnostics for invalid plugin configuration and late registrations.
- Added checks for missing bundled-plugin guard definitions during loading.
- Improved duplicate-registration reporting while continuing to process remaining registrations.

@PARAM

Comments only -- every changed file is token-identical outside its comments, and every @PARAM, @return, @var and @throws survives with its type, which level 9 reads. The rationale had been written twice: once in AGENTS.md, which is the durable document, and again in the file it described. Boot/Scheduler shared 52 phrases with it, Provider 35, Loader 25. Within src/ the same arguments repeated too -- the reader-drains-the-buffer note in four files, the hook-prefix stand-down in three, the Throwable catch in three. Each now has one home and a clause everywhere else. Prose in src/ goes 14,876 words to 6,873.

The how-to file had been re-explaining the mechanisms the reference files own. recipes.md restated conflict-handling.md's "a policy is only reached for a sub-plugin that is enabled..." at 93% overlap, and configuration.md's activation record semantics again; conflict-handling.md restated notices.md's render-then-clear. Each fact now sits in the file whose subject it is, and the links already in the text carry the reader. Every heading and every link is byte-identical, so the anchors other files target still resolve. Code blocks, the mermaid diagram and table rows are untouched. 8,084 words to 6,047. filters.md and the README are already dense and keep their length.

📝 Walkthrough

Walkthrough

The pull request revises public guides and inline documentation for configuration, boot timing, loading, conflict resolution, notices, activation tracking, plugin state, extension points, and multisite behavior. Runtime changes add registration-window checks, host-plugin validation, guard-constant diagnostics, and more specific developer-error identifiers.

Changes

Documentation and lifecycle clarification

Layer / File(s)	Summary
Public guides and configuration semantics `README.md`, `docs/*.md`	The guides clarify configuration, callable values, filters, loading and activation behavior, conflict policies, notices, installation, recipes, and multisite handling.
Bootstrap, registry, and loading behavior `src/Absorber.php`, `src/Activator.php`, `src/Boot/`, `src/Config.php`, `src/Loader.php`, `src/Provider.php`, `src/Registry/`, `src/Sub_Plugin.php`	Inline documentation clarifies container binding, registration buffering, boot scheduling, activation records, configuration naming, and deferred values. Scheduler and registry changes report late registration, and loader changes validate guard constants after loading.
Conflict resolution and request handling `src/Conflict/`, `src/Conflict_Policy.php`, `src/Plugin/`, `src/Traits/*`	Inline documentation clarifies request gates, capability checks, conflict detection, redirects, fatal rewriting, policy validation, plugin state, and multisite scope. Detector validation checks configured host plugin basenames before stranding evaluation.
Sub-plugin, notice, and extension contracts `src/Notices/`, `src/Contracts/`	Documentation clarifies deferred configuration, validation, activation semantics, notice storage, rendering, queue consumption, and extension responsibilities.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to ec7c0

The PR changes documentation and comments only, but the current head still contains inaccurate configuration and retry semantics, a misleading scheduler API reference, an undefined README link, and a diagnostic callback path that can escape registration; these can mislead maintainers or surface unexpected failures, so merge should wait for targeted corrections or explicit owner acceptance.

Inline comments:
In `@docs/configuration.md`:
- Around line 111-113: Update the documentation near the bundled plugin’s
main-file example to state the exact priority boundary: callbacks defining
plugin_loaded_constant on plugins_loaded at priorities 0–4 run before the
priority-5 guard and cause the bundled copy to be skipped; do not describe all
plugins_loaded callbacks as equivalent to later execution.

In `@src/Boot/Scheduler.php`:
- Line 45: Update the comment near the scheduler priority rationale to name the
actual Config::set_container() API instead of Harbor, preserving the explanation
that hosts wire it at priority 1.

In `@src/Conflict/Detector.php`:
- Around line 19-21: Update the Detector class documentation to replace the
broad “Everything here only reports” claim: state that it does not change plugin
activation state, and document that Reader::all() drains buffered registrations
while apply_filters() executes host code.

In `@src/Loader.php`:
- Around line 164-166: Update the comment above the should_load apply_filters
call to accurately state that PHP truthy non-boolean values, including non-empty
arrays, objects, or strings, cause the subsequent load condition to proceed;
remove the claim that unexpected values are merely falsy. Leave the $should_load
behavior unchanged.
- Around line 68-69: Update the load_all() PHPDoc `@throws` declaration to match
the method’s actual exception handling: remove the Config_Exception annotation
because registry and plugin-loading failures are caught within the method,
including Throwable from each load() call.
- Around line 176-179: Update the comment immediately above
activator->maybe_run() in Loader so it accurately states that maybe_run()
executes only after require_once returns; remove the claim that skipped loads
consume the once-ever activation record, while preserving the explanation that
this substitutes for register_activation_hook() for included plugins.

In `@src/Plugin/Contracts/Checker_Interface.php`:
- Around line 11-12: Update the documentation comments for Checker_Interface at
src/Plugin/Contracts/Checker_Interface.php:11-12 and Deactivator_Interface at
src/Plugin/Contracts/Deactivator_Interface.php:13-13 to describe replacement
behavior declaratively rather than instructing the reader; state that
replacements can answer from a source other than the active-plugins option, and
can make deactivation a no-op when plugin state is managed outside WordPress,
respectively.

In `@src/Provider.php`:
- Around line 154-158: Update the binding-precedence documentation in
src/Provider.php lines 154-158 to state that pre-existing bindings are preserved
only for interface IDs, while concrete class bindings may be replaced during
boot. Reconcile docs/extending.md lines 154-158 with that rule and the earlier
binding-timing statement, explicitly distinguishing interface and class IDs; no
implementation change is required.

In `@src/Sub_Plugin.php`:
- Around line 188-189: Update is_enabled() to treat configured string values as
non-callable values before the invocation branch: exclude strings from the
is_callable() guard, while continuing to evaluate callable arrays and invokable
objects and cast other values to bool. Revise the nearby enabled-behavior
comments to document that strings remain values and are not invoked.

The should_load comment said an odd return is merely falsy and skips: a non-empty array, an object or a string is truthy and loads. The activator comment blamed the once-ever record on a skipped load, which cannot reach it -- every gate returns first; the real danger is running the callback for code that is not in memory. The detector claimed to only report, while the read it makes drains the buffer and its filters run host code; what it never does is change an activation state. The load guard's boundary is priority 6, not "plugins_loaded or later", and it belongs in the file whose subject is the guard. Extending says which ids may be bound before boot, and points at the section that owns the class-name rule rather than restating it. Naming the hosts that wire at priority 1 keeps Harbor readable as somebody else's API.

Nothing about a Sub_Plugin accessor's throw is recorded: it is reported and the pass moves on, and plugins_loaded fires again on the next request. The one place a retry is a decision rather than an accident is the activation callback, which records after the callback returns for exactly that reason.

The bullet landed with the lifecycle actions; its reference definition did not, so "Actions" renders as literal brackets between two working links.

Keep diagnostic callbacks inside the hook boundary.

When late registration calls _doing_it_wrong(), WordPress invokes doing_it_wrong_run and evaluates doing_it_wrong_trigger_error. A throwing callback can escape Absorber::register() because Reader::buffer() has no Throwable boundary. Catch diagnostic failures locally after buffering the registration.
