TinyAuth's setup examples included invalid public-action INI and Authentication 4 identifier configuration. This change makes Installation precede Getting started, verifies those examples with the actual adapters and Authentication service, and explains the services, identities, routes and role data the application must already provide.

Request authorization now preserves policy result details and sends policy exceptions through the configured unauthorized handler. Explicit INI deny rules remove previously allowed controller actions, including when no public actions remain. ACL commands report dry runs accurately, stop when no controllers are available, and fail when the ACL file cannot be written. Controller discovery matches public rules within their plugin and prefix instead of skipping unrelated controllers with the same name.

The documentation corrects middleware policy registration, component callback timing, persistent identity caching, impersonation identity changes, custom adapter setup and removed Auth-component calls. It distinguishes action access from record permissions. The existing SVG branding and searchable website are retained, with patched docs dependencies and read-only pull-request builds; Pages write permissions are limited to deployment.

Validation:

  • PHPUnit: 167 tests and 511 assertions, without deprecations or PHPUnit notices.
  • Coding standards and PHPStan level 8 pass.
  • All 91 PHP snippets parse with their documented fragment context; Authentication 4 and impersonation configurations load directly from the docs, and beginner INI examples pass through the actual adapters.
  • Documentation builds and npm audit pass with zero vulnerabilities.
  • Browser checks cover navigation order, SVG branding, search, dark mode, mobile layout and 142 internal links without JavaScript errors.
  • GitHub CI covers PHP 8.2 and 8.5, SQLite/MySQL/PostgreSQL, minimum dependencies, static checks and translation catalogs.

Rule caches are scoped to their adapter configuration and role map. Logout clears the impersonation marker, public-action checks share deny precedence, and controller discovery retains nested prefixes. Regression tests cover these cases.

Changelog content is unchanged. The source and documentation review is complete.

📝 Walkthrough

Walkthrough

The pull request updates authorization rule caching and checks, controller discovery, ACL command behavior, and impersonation cleanup. It also revises TinyAuth documentation and adds a documentation build workflow.

Changes

Authorization rules and cache

Layer / File(s) Summary
Context-scoped rule caching
src/Auth/*, src/Utility/Cache.php, src/Utility/SessionCache.php, tests/TestCase/Utility/*, docs/guide/configuration.md, docs/guide/troubleshooting.md
Allow and ACL rule caches use configuration fingerprints. Cache reads and writes validate the context, and tests cover configuration changes and cache selection.
Controller and request authorization
src/Auth/AclTrait.php, src/Controller/Component/AuthenticationComponent.php, src/Middleware/RequestAuthorizationMiddleware.php, tests/TestCase/Controller/Component/*, tests/TestCase/Middleware/*, tests/TestCase/Policy/*
Authentication preparation handles empty and wildcard-denied action lists. Request authorization checks policy result status. Tests cover denied rules, public actions, and policy results.

Controller discovery and ACL commands

Layer / File(s) Summary
Prefix-aware controller scanning
src/Sync/Adder.php, src/Sync/Syncer.php, tests/TestCase/Utility/ControllerDiscoveryTest.php
Controller discovery retains nested prefixes and includes plugin and prefix names when matching allow rules.
ACL command outcomes and file writes
src/Command/*Command.php, src/Sync/Adder.php, src/Sync/Syncer.php, src/Utility/Utility.php, tests/TestCase/Command/*, tests/TestCase/Utility/UtilityTest.php
Add and sync report file-generation failures. Add reports an error when no controllers are available, and both commands provide dry-run-specific output.

Impersonation session cleanup

Layer / File(s) Summary
Identity cleanup and impersonation behavior
src/Authenticator/PrimaryKeySessionAuthenticator.php, tests/TestCase/Authenticator/PrimaryKeySessionAuthenticatorTest.php
Clearing identity deletes the configured impersonation session key. Tests cover custom keys and stopping impersonation after a new identity is persisted.

Documentation and docs delivery

Layer / File(s) Summary
Documentation entry points and setup
README.md, docs/index.md, docs/guide/index.md, docs/guide/install.md, docs/guide/quick-start.md, docs/.vitepress/config.ts
The project overview and setup guides describe TinyAuth’s scope, prerequisites, installation, and quick-start configuration.
Authentication and identity guides
docs/auth-panel.md, docs/auth-user.md, docs/authentication/*, src/Auth/AuthUserTrait.php, src/Auth/TinyAuthorize.php
Authentication documentation updates setup examples, adapter formats, identity requirements, and impersonation behavior. Source comments describe trait and adapter roles.
Authorization, roles, and adapter guides
docs/authorization/*, docs/guide/configuration.md, docs/guide/custom-adapters.md
Authorization documentation describes middleware and component checks, role sources, adapter formats, and cache behavior.
CLI and maintenance references
docs/reference/cli.md, docs/guide/upgrade.md
The CLI guide documents controller defaults and a preview-first sync workflow. The upgrade guide describes cache and maintenance details.
Documentation build and deployment
.github/workflows/deploy-docs.yml, .github/workflows/docs-check.yml, docs/package.json
The deployment workflow scopes permissions to its deploy job and uses Node.js 24. A new workflow builds the docs on matching pull requests or manual dispatch; the docs package pins the Vite override.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Change: Bug fix


Merge Risk: 🔵 Low · up to d2a46

Rule caching keeps one cache entry per rule type, so alternating configurations re-parse their rule files. This is a bounded performance cost, and authorization decisions remain correct. It can be addressed in a follow-up.

69-70: 🚀 Performance & Scalability | 🔵 Trivial | ⚖️ Poor tradeoff

Treat per-context rule slots as an optional optimization, not a major issue.

When contexts alternate, Cache::read() can miss after a context mismatch, so _getAllow() or _getAcl() parses and writes the rules again. This affects cache efficiency only.

If multi-context deployments are a supported target, use context-specific keys and maintain an index that lets clear($type) and clear() delete every context entry. This is nontrivial bookkeeping. The inspected production references do not establish that deployments alternate rule configurations, so the benefit is limited.

they provide `toArray()`, implement `Traversable`, or implement `Countable`.
Keep the existing requirement for `getOriginalData()` and the note that raw
