-# Project
-
-PHP library (tiny-blocks ecosystem). Self-contained package: immutable models, zero infrastructure
-dependencies in core, small public surface area. Public API at `src/` root; implementation details
-under `src/Internal/`.
-
-## Rules
-
-All coding standards, architecture, naming, testing, and documentation conventions
-are defined in `rules/`. Read the applicable rule files before generating any code or documentation.
-
-## Commands
-
-- `make test` — runs PHPUnit (with coverage) and Infection (mutation testing) sequentially via `composer tests`.
-- `make review` — run lint.
-- `make help` — list all available commands.
-
-## Post-change validation
-
-After any code change, run `make review`, `make test`, and `make mutation-test`.
-If any fails, iterate on the fix while respecting all project rules until all pass.
-Never deliver code that breaks lint, tests, or leaves surviving mutants.
-
-## File formatting
-
-Every file produced or modified must:
-
-- Use **LF** line endings. Never CRLF.
-- Have no trailing whitespace on any line.
-- End with a single trailing newline.
-- Have no consecutive blank lines (max one blank line between blocks).
+# CLAUDE.md

-# Workflows
-
-Structural and stylistic rules for GitHub Actions workflow files. Refer to `shell-scripts.md` for Bash conventions used
-inside `run:` steps, and to `terraforms.md` for Terraform conventions used in `terraform/`.
-
-## Pre-output checklist
-
-Verify every item before producing any workflow YAML. If any item fails, revise before outputting.
-
-1. File name follows the convention: `ci-.yml` for reusable CI, `cd-.yml` for dispatch CD.
-2. `name` field follows the pattern `CI — ` or `CD — `, using sentence case after the dash
- (e.g., `CD — Run migration`, not `CD — Run Migration`).
-3. Reusable workflows use `workflow_call` trigger. CD workflows use `workflow_dispatch` trigger.
-4. Each workflow has a single responsibility. CI tests code. CD deploys it. Never combine both.
-5. Every input has a `description` field. Descriptions use American English and end with a period.
-6. Input names use `kebab-case`: `service-name`, `dry-run`, `skip-build`.
-7. Inputs are ordered: required first, then optional. Each group by **name length ascending**.
-8. Choice input options are in **alphabetical order**.
-9. `env`, `outputs`, and `with` entries are ordered by **key length ascending**.
-10. `permissions` keys are ordered by **key length ascending** (`contents` before `id-token`).
-11. Top-level workflow keys follow canonical order: `name`, `on`, `concurrency`, `permissions`, `env`, `jobs`.
-12. Job-level properties follow canonical order: `if`, `name`, `needs`, `uses`, `with`, `runs-on`,
- `environment`, `timeout-minutes`, `strategy`, `outputs`, `permissions`, `env`, `steps`.
-13. All other YAML property names within a block are ordered by **name length ascending**.
-14. Jobs follow execution order: `load-config` → `lint` → `test` → `build` → `deploy`.
-15. Step names start with a verb and use sentence case: `Setup PHP`, `Run lint`, `Resolve image tag`.
-16. Runtime versions are resolved from the service repo's native dependency file (`composer.json`, `go.mod`,
- `package.json`). No version is hardcoded in any workflow.
-17. Service-specific overrides live in a pipeline config file (e.g., `.pipeline.yml`) in the service repo,
- not in the workflows repository.
-18. The `load-config` job reads the pipeline config file at runtime with safe fallback to defaults when absent.
-19. Top-level `permissions` defaults to read-only (`contents: read`). Jobs escalate only the permissions they
- need.
-20. AWS authentication uses OIDC federation exclusively. Static access keys are forbidden.
-21. Secrets are passed via `secrets: inherit` from callers. No secret is hardcoded.
-22. Sensitive values fetched from SSM are masked with `::add-mask::` before assignment.
-23. Third-party actions are pinned to the latest available full commit SHA with a version comment:
- `uses: aws-actions/configure-aws-credentials@ # v4.0.2`. Always verify the latest
- version before generating a workflow.
-24. First-party actions (`actions/*`) are pinned to the latest major version tag available:
- `actions/checkout@v4`. Always check for the most recent major version before generating a workflow.
-25. Production deployments require GitHub Environments protection rules (manual approval).
-26. Every job sets `timeout-minutes` to prevent indefinite hangs. CI jobs: 10–15 minutes. CD jobs: 20–30
- minutes. Adjust only with justification in a comment.
-27. CI workflows set `concurrency` with `group` scoped to the PR and `cancel-in-progress: true` to avoid
- redundant runs.
-28. CD workflows set `concurrency` with `group` scoped to the environment and `cancel-in-progress: false` to
- prevent interrupted deployments.
-29. CD workflows use `if: ${{ !cancelled() }}` to allow to deploy after optional build steps.
-30. Inline logic longer than 3 lines is extracted to a script in `scripts/ci/` or `scripts/cd/`.
-
-## Style
-
-- All text (workflow names, step names, input descriptions, comments) uses American English with correct
- spelling and punctuation. Sentences and descriptions end with a period.
-
-## Callers
-
-- Callers trigger on `pull_request` targeting `main` only. No `push` trigger.
-- Callers in service repos are static (~10 lines) and pass only `service-name` or `app-name`.
-- Callers reference workflows with `@main` during development. Pin to a tag or SHA for production.
-
-## Image tagging
-
-- CD deploy builds: `-sha-` + `latest`.
-
-## Migrations
-
-- Migrations run **before** service deployment (schema first, code second).
-- `cd-migrate.yml` supports `dry-run` mode (`flyway validate`) for pre-flight checks.
-- Database credentials are fetched from SSM at runtime, never stored in workflow files.

+description: Folder structure, public API boundary, and Internal/ semantics for PHP libraries.
+paths:
+ - "src/**/*.php"
+---
+
+# Architecture
+
+Covers the physical layout of the library. Folder structure, the boundary between public API and
+implementation detail, and where each type of class lives. Semantic rules (value objects,
+exceptions, enums, complexity, nomenclature) live in `php-library-modeling.md`. Code style lives
+in `php-library-code-style.md`.
+
+## Pre-output checklist
+
+Verify every item before producing or relocating any file. If any item fails, revise before
+outputting.
+
+1. None of the following folder names exist in `src/`: `Models/`, `Entities/`, `ValueObjects/`,
+ `Enums/`, `Domain/`. They carry no semantic content and conflate technical role with domain
+ meaning.
+2. The `src/` root contains only interfaces, extension points, public enums, thin orchestration
+ classes, and primary implementations or façades. Substantial logic (algorithms, state machines,
+ I/O) lives in `src/Internal/`, never at the root.
+3. `src/Internal/` is implementation detail and not part of the public API. Breaking changes
+ inside `src/Internal/` are not semver-breaking.
+4. Consumers must not reference, extend, or depend on any type inside `src/Internal/`. The
+ namespace itself is the boundary.
+5. Public exception classes live in `src/Exceptions/`.
+6. Internal exception classes live in `src/Internal/Exceptions/`.
+7. Public enums live at the `src/` root or inside a public `/` folder. Enums used
+ only by internals live in `src/Internal/`.
+8. Public interfaces live at the `src/` root or inside a public `/` folder.
+9. A `/` folder at the `src/` root groups related public types under a shared
+ concept. Each group has its own namespace and is part of the public API.
+10. `/` is optional. Use it only when the library exposes several coherent groups of
+ types (for example, aggregates and events) rather than a flat set of types around a single
+ concept.
+11. Test fixtures representing domain concepts live in `tests/Models/`. Test doubles for system
+ boundaries live at the root of `tests/Unit/` or `tests/Integration/`. No dedicated `Mocks/`
+ or `Doubles/` subdirectory exists. `tests/Drivers//` is permitted when the library
+ exposes a port exercised against multiple third-party implementations (PSR adapters,
+ framework integrations). Each `/` subdir holds tests against one specific
+ implementation.
+12. The `tests/Integration/` folder exists only when the library interacts with external
+ infrastructure (filesystem, database, network). Otherwise, the folder is absent.
+
+## Folder structure
+
+Canonical layout for a PHP library in the tiny-blocks ecosystem.
+
+```
+src/
+├── .php # public contract at root
+├── .php # main implementation or extension point at root
+├── .php # public enum at root
+├── / # public folder grouping related public types under a shared concept
+│ ├── .php
+│ └── ...
+├── Internal/ # implementation details, not part of the public API
+│ ├── .php
+│ └── Exceptions/ # internal exception classes
+└── Exceptions/ # public exception classes
+
+tests/
+├── Models/ # domain fixtures reused across tests
+├── Unit/ # unit tests targeting the public API
+│ ├── .php # test doubles at root of Unit/
+│ └── .php
+└── Integration/ # only present when the library interacts with infrastructure
+ └── .php # test doubles at root of Integration/ when needed
+```
+
+Never use `Models/`, `Entities/`, `ValueObjects/`, `Enums/`, or `Domain/` as folder names. They
+carry no semantic content and describe technical role instead of domain meaning.
+
+## Public API boundary
+
+The `src/` root is the contract. Everything at the root, plus everything inside public
+`/` folders and the public `Exceptions/` folder, is what consumers depend on. Changes
+to these types follow semver rules.
+
+`src/Internal/` is implementation detail. The namespace itself signals the boundary. Consumers
+must not depend on any type inside `src/Internal/`. Breaking changes inside `src/Internal/` are
+not semver-breaking for the library.
+
+### What lives at the public boundary
+
+- Interfaces that define contracts for consumers.
+- Extension points designed to be subclassed or composed by consumers.
+- Public enums and value objects consumers manipulate directly.
+- Thin orchestration classes that wire collaborators together without containing substantial logic.
+- Public exception classes consumers may catch.
+
+### What lives in `src/Internal/`
+
+- Algorithms, state machines, and complex transformations.
+- Adapters for I/O (filesystem, network, database).
+- Collaborators that exist purely to break a public class into testable units.
+- Implementation details that may change between minor or patch releases.
+- Internal exception classes raised by collaborators.
+
+## Reference examples
+
+### Small library with flat root
+
+```
+src/
+├── Timezone.php # public value object
+├── Timezones.php # public collection
+├── Clock.php # public interface
+└── Internal/
+ ├── SystemClock.php # default Clock implementation
+ └── Exceptions/
+ └── InvalidTimezone.php
+```
+
+Everything lives at the root or inside `Internal/`. No `/` folders. Suitable when
+the library exposes a small, cohesive set of types around a single concept.
+
+### Library with public concept groups
+
+```
+src/
+├── ValueObject.php # public extension point at root
+├── Aggregate/ # public namespace grouping aggregate types
+│ ├── AggregateRoot.php
+│ ├── EventualAggregateRoot.php
+│ └── ModelVersion.php
+├── Event/ # public namespace grouping event types
+│ ├── EventRecord.php
+│ ├── EventRecords.php
+│ └── SequenceNumber.php
+├── Internal/
+│ ├── DefaultModelVersionResolver.php
+│ └── Exceptions/
+│ └── InvalidSequenceNumber.php
+└── Exceptions/
+ └── EventRecordingFailure.php
+```
+
+`Aggregate/` and `Event/` are public folders at the root, each grouping a coherent set of public
+types under one shared concept. Consumers import directly, for example
+`TinyBlocks\\Aggregate\AggregateRoot`. Suitable when the library exposes several distinct
+concept areas, each with its own set of related types.

+Semantic rules for all PHP files in libraries. Formatting rules covered by `PSR-12` are enforced

## Pre-output checklist
Verify every item before producing any PHP code. If any item fails, revise before outputting.
1. `declare(strict_types=1)` is present.
-2. All classes are `final readonly` by default. Use `class` (without `final` or `readonly`) only when the class is
- designed as an extension point for consumers (e.g., `Collection`, `ValueObject`). Use `final class` without
- `readonly` only when the parent class is not readonly (e.g., extending a third-party abstract class).
-3. All parameters, return types, and properties have explicit types.
-4. Constructor property promotion is used.
-5. Named arguments are used at call sites for own code, tests, and third-party library methods (e.g., tiny-blocks).
- Never use named arguments on native PHP functions (`array_map`, `in_array`, `preg_match`, `is_null`,
- `iterator_to_array`, `sprintf`, `implode`, etc.) or PHPUnit assertions (`assertEquals`, `assertSame`,
- `assertTrue`, `expectException`, etc.).
-6. No `else` or `else if` exists anywhere. Use early returns, polymorphism, or map dispatch instead.
-7. No abbreviations appear in identifiers. Use `$index` instead of `$i`, `$account` instead of `$acc`.
-8. No generic identifiers exist. Use domain-specific names instead:
- `$data` → `$payload`, `$value` → `$totalAmount`, `$item` → `$element`,
- `$info` → `$currencyDetails`, `$result` → `$conversionOutcome`.
-9. No raw arrays exist where a typed collection or value object is available. Use the `tiny-blocks/collection`
- fluent API (`Collection`, `Collectible`) when data is `Collectible`. Use `createLazyFrom` when elements are
- consumed once. Raw arrays are acceptable only for primitive configuration data, variadic pass-through, and
- interop at system boundaries. See "Collection usage" below for the full rule and example.
-10. No private methods exist except private constructors for factory patterns. Inline trivial logic at the call site
- or extract it to a collaborator or value object.
-11. Members are ordered: constants first, then constructor, then static methods, then instance methods. Within each
- group, order by body size ascending (number of lines between `{` and `}`). Constants and enum cases, which have
- no body, are ordered by name length ascending.
-12. Constructor parameters are ordered by parameter name length ascending (count the name only, without `$` or type),
- except when parameters have an implicit semantic order (e.g., `$start/$end`, `$from/$to`, `$startAt/$endAt`),
- which takes precedence. Parameters with default values go last, regardless of name length. The same rule
- applies to named arguments at call sites.
- Example: `$id` (2) → `$value` (5) → `$status` (6) → `$precision` (9).
-13. Time and space complexity are first-class design concerns.
- - No `O(N²)` or worse time complexity exists unless the problem inherently requires it and the cost is
- documented in PHPDoc on the interface method.
- - Space complexity is kept minimal: prefer lazy/streaming pipelines (`createLazyFrom`) over materializing
- intermediate collections.
- - Never re-iterate the same source; fuse stages when possible.
- - Public interface methods document time and space complexity in Big O form (see "PHPDoc" section).
+2. All parameters, return types, and properties have explicit types.
+3. Constructor property promotion is used.
+4. Named arguments are used at call sites for own code, tests, and third-party library methods
+ (for example, tiny-blocks). Never use named arguments on:
+ - Native PHP functions (`array_map`, `in_array`, `preg_match`, `is_null`,
+ `iterator_to_array`, `sprintf`, `implode`, and similar).
+ - Native PHP enum methods (`from`, `tryFrom`, `cases`).
+ - PHPUnit assertions and expectations (`assertEquals`, `assertSame`, `assertTrue`,
+ `expectException`, and similar).
+ - Interfaces from PHP-FIG PSR standards (PSR-7 `withHeader`, PSR-18 `sendRequest`, etc.).
+ The PSR contract does not include parameter names. Implementations may rename parameters.
+ - Calls that include variadic spread (`...$args`). PHP rejects positional argument unpacking
+ after named arguments. When the caller passes through a `...$variadic`, all arguments are
+ positional. New own-code APIs should prefer a typed collection parameter over a variadic
+ so named-argument call sites remain possible.
+
+ Native PHP **class constructors** (`parent::__construct` calls to `\Exception`,
+ `\RuntimeException`, `\InvalidArgumentException`, `\LogicException`, and similar) are not
+ in the list above. They accept named arguments, and rule 8 requires using them whenever
+ the positional call would pass an argument whose value equals the parameter's default.
+ Example: `parent::__construct(message: sprintf(...), previous: $previous)` instead of
+ `parent::__construct(sprintf(...), 0, $previous)`. The exclusion above covers native
+ functions and enum methods, not native class instantiation.
+5. Classes follow the rules in "Inheritance and constructors". `final readonly` is the default,
+ with documented exceptions for extension points and for parents that are not `readonly`.
+6. Members are ordered constants first, then constructor, then static methods, then instance
+ methods. Within each group, order by body size ascending (number of lines between `{` and `}`).
+ Constants and enum cases, which have no body, are ordered by name length ascending. This
+ ordering may be overridden only when the alternative carries explicit documentation value:
+ grouping by domain class with section markers (HTTP status codes by 1xx/2xx/3xx/etc),
+ mirroring the order of an implemented interface, or similar evident structure. The override
+ must be obvious at first reading.
+
+ **At call sites** (chained method calls in production code, tests, or documentation
+ examples), consecutive method invocations on the same receiver are ordered by the **visible
+ width** of each call expression ascending. The body is not visible at the call site, so the
+ visible width is the practical proxy for body size. Boolean toggles such as `->secure()` and
+ `->httpOnly()` come before parameterized `with*` builders for the same reason. When two
+ calls have equal width, order them alphabetically by method name.
+
+ **Terminal methods that change the receiver type** stay at the end of the chain regardless
+ of width. A `build()` that returns the built value, a `commit()` that finalizes a unit of
+ work, a `send()` that flushes a request, are terminal: the chain ends with them. The
+ ordering rule applies only to consecutive calls on the same receiver type; calls that
+ transition to a different type are not reorderable. The same applies in reverse to the
+ factory or accessor that starts the chain (`Cookie::create(...)`, `$repository`) — it stays
+ at its position.
+7. Constructor parameters are ordered by parameter name length ascending (count the name only,
+ without `$` or type), except when parameters have an implicit semantic order (for example,
+ `$start/$end`, `$from/$to`, `$startAt/$endAt`), which takes precedence. Parameters with default
+ values go last, regardless of name length. The same rule applies to named arguments at call
+ sites. Example order: `$id` (2), `$value` (5), `$status` (6), `$precision` (9).
+8. Never pass an argument whose value equals the parameter's default. Omit the argument entirely.
+ Example with `toArray(KeyPreservation $keyPreservation = KeyPreservation::PRESERVE)`. The call
+ `$collection->toArray(keyPreservation: KeyPreservation::PRESERVE)` becomes
+ `$collection->toArray()`. Only pass the argument when the value differs from the default.
+9. No `else` or `else if` exists anywhere. Use early returns, polymorphism, or map dispatch instead.
+10. No abbreviations appear in identifiers. Use `$index` instead of `$i`, `$account` instead of
+ `$acc`.
+11. No generic identifiers exist. Use domain-specific names instead. Examples are `$data` to
+ `$payload`, `$value` to `$totalAmount`, `$item` to `$element`, `$info` to `$currencyDetails`,
+ `$result` to `$conversionOutcome`.
+12. No raw arrays exist where a typed collection or value object is available. When data is
+ `Collectible`, use the `tiny-blocks/collection` fluent API (`Collection`, `Collectible`). Use
+ `createLazyFrom` when elements are consumed once. Raw arrays are acceptable only for primitive
+ configuration data, variadic pass-through, and interop at system boundaries. See "Collection
+ usage" for the full rule and example.
+13. No private methods exist except for private constructors in factory patterns, methods inside
+ `src/Internal/` (implementation detail by definition, where the namespace is the abstraction
+ boundary), and `setUp` or `tearDown` overrides in PHPUnit test classes. Outside these cases,
+ inline trivial logic at the call site or extract it to a collaborator or value object.
14. No logic is duplicated across two or more places (DRY).
15. No abstraction exists without real duplication or isolation need (KISS).
-16. All identifiers, comments, and documentation are written in American English.
-17. No justification comments exist (`// NOTE:`, `// REASON:`, etc.). Code speaks for itself.
-18. `// TODO: ` is used when implementation is unknown, uncertain, or intentionally deferred.
- Never leave silent gaps.
-19. All class references use `use` imports at the top of the file. Fully qualified names inline are prohibited.
-20. No dead or unused code exists. Remove unreferenced classes, methods, constants, and imports.
-21. Never create public methods, constants, or classes in `src/` solely to serve tests. If production code does not
- need it, it does not exist.
-22. Always use the most current and clean syntax available in the target PHP version. Prefer match to switch,
- first-class callables over `Closure::fromCallable()`, readonly promotion over manual assignment, enum methods
- over external switch/if chains, named arguments over positional ambiguity (except where excluded by rule 5),
- and `Collection::map` over foreach accumulation.
-23. No vertical alignment of types in parameter lists or property declarations. Use a single space between
- type and variable name. Never pad with extra spaces to align columns:
- `public OrderId $id` — not `public OrderId $id`.
-24. Opening brace `{` follows PSR-12: on a **new line** for classes, interfaces, traits, enums, and methods
- (including constructors); on the **same line** for closures and control structures (`if`, `for`, `foreach`,
- `while`, `switch`, `match`, `try`).
-25. Never pass an argument whose value equals the parameter's default. Omit the argument entirely.
- Example — `toArray(KeyPreservation $keyPreservation = KeyPreservation::PRESERVE)`:
- `$collection->toArray(keyPreservation: KeyPreservation::PRESERVE)` → `$collection->toArray()`.
- Only pass the argument when the value differs from the default.
-26. No trailing comma in any multi-line list. This applies to parameter lists (constructors, methods,
- closures), argument lists at call sites, array literals, match arms, and any other comma-separated
- multi-line structure. The last element never has a comma after it. PHP accepts trailing commas in
- parameter lists, but this project prohibits them for visual consistency.
- Example — correct:
- ```
- new Precision(
- value: 2,
- rounding: RoundingMode::HALF_UP
- );
- ```
- Example — prohibited:
- ```
- new Precision(
- value: 2,
- rounding: RoundingMode::HALF_UP,
- );
- ```
+16. No inline comments exist in `src/` or `tests/`, except `# TODO: ` when implementation
+ is unknown, uncertain, or intentionally deferred. Code is the documentation. Block comments
+ (`/* */`) never appear outside docblocks (`/** */`). The `#` style for inline PHP comments
+ applies only to code examples inside Markdown files (see `php-library-documentation.md`).
+17. No dead or unused code exists. Remove unreferenced classes, methods, constants, and imports.
+18. Never create public methods, constants, or classes in `src/` solely to serve tests. If
+ production code does not need it, it does not exist.
+19. Format strings with placeholders (`%s`, `%d`, `%f`, etc.) are assigned to a `$template`
+ variable before being passed to `sprintf`. The variable assignment and the `sprintf` call live
+ on separate statements. See "Format strings" for examples.
+20. All class references use `use` imports at the top of the file. Fully qualified names inline are
+ prohibited.
+21. Return types and `new` calls use the explicit class name. `self` is prohibited as a type,
+ as a return type, and in `new self()` instantiation. Constant access via `self::CONST_NAME`
+ is permitted. `static` is permitted only inside extension-point classes (declared `class`
+ without `final readonly`) and inside traits, where late static binding lets subclasses or
+ consuming classes instantiate the correct concrete type. In every other context, use the
+ class name.
+22. Always use the most current and clean syntax available in the target PHP version. Prefer
+ `match` over `switch`, first-class callables over `Closure::fromCallable()`, readonly promotion
+ over manual assignment, enum methods over external switch or if chains, named arguments over
+ positional ambiguity (except where excluded by rule 4), `Collection::map` over foreach
+ accumulation, and **unparenthesized constructor chaining** (PHP 8.4+):
+ `new Foo()->bar()` instead of `(new Foo())->bar()`. The parentheses around the `new`
+ expression are no longer required and add visual noise.
+23. All identifiers, comments, and documentation use American English. See "American English" for
+ the spelling list.
-## Casing conventions
+## Naming
-- Internal code (variables, methods, classes): **`camelCase`**.
-- Constants and enum-backed values when representing codes: **`SCREAMING_SNAKE_CASE`**.
+- Internal code (variables, methods, classes) uses `camelCase`.
+- Constants and enum-backed values when representing codes use `SCREAMING_SNAKE_CASE`.
+- Names describe what in domain terms, not how technically. `$monthlyRevenue` instead of
+ `$calculatedValue`. Generic technical verbs are avoided. See `php-library-modeling.md` for the
+ full banlist of generic and anemic names.
+- Booleans use predicate form. Examples are `isActive`, `hasPermission`, `wasProcessed`.
+- Collections are always plural. Examples are `$orders`, `$lines`.
+- Methods returning `bool` use prefixes `is`, `has`, `can`, `was`, `should`.
-## Naming
+## Class self-references
+
+Type declarations, return types, and `new` calls inside a class use the explicit class name.
+The class name is unambiguous, survives refactors that move the method to a different class,
+and reads identically inside the class body and at the call site.
+
+- `self` is prohibited everywhere as a type, as a return type, and in `new self()`
+ instantiation. Constant access via `self::CONST_NAME` is **permitted**. The prohibition
+ covers the forms that carry refactoring ambiguity when a method moves to a different class
+ (the type-or-instantiation forms). Constant access does not have that ambiguity because the
+ constant is declared in the same class body.
+- `static` is permitted only inside extension-point classes (declared `class` without
+ `final readonly`) and inside traits, where late static binding is required for subclasses or
+ consuming classes to instantiate the correct concrete type.
+- In every other context (the default `final readonly class`, factory methods, return types),
+ use the class name.
+
+**Prohibited.** `self` as return type and `new self()` inside a final class:
+
+```php
+final readonly class UserAgent
+{
+ public static function from(string $product): self
+ {
+ return new self(product: $product);
+ }
+}
+```
+
+**Correct.** Explicit class name in a final class:
+
+```php
+final readonly class UserAgent
+{
+ public static function from(string $product): UserAgent
+ {
+ return new UserAgent(product: $product);
+ }
+}
+```
-- Names describe **what** in domain terms, not **how** technically: `$monthlyRevenue` instead of `$calculatedValue`.
-- Generic technical verbs are avoided. See `php-library-modeling.md` — Nomenclature.
-- Booleans use predicate form: `isActive`, `hasPermission`, `wasProcessed`.
-- Collections are always plural: `$orders`, `$lines`.
-- Methods returning bool use prefixes: `is`, `has`, `can`, `was`, `should`.
+**Correct.** `static` permitted in an extension-point class:
+
+```php
+class Collection
+{
+ public static function createFrom(iterable $elements): static
+ {
+ return new static(elements: $elements);
+ }
+}
+```
+
+## Inheritance and constructors
+
+- All classes are `final readonly` by default.
+- Use `class` (without `final` or `readonly`) only when the class is designed as an extension point
+ for consumers, for example `Collection` or `ValueObject`.
+- Use `final class` without `readonly` only when the parent class is not readonly, for example
+ when extending a third-party abstract class.
+- Use `final class` without `readonly` is also permitted for `src/Internal/` collaborators that
+ carry intrinsically mutable state (resource handles, counters, cursors) where the mutation is
+ central to the class's responsibility (`Stream` closing a resource, `Cursor` advancing a
+ position). The class must remain confined to `src/Internal/`.
+- Use `final class` without `readonly` for classes that consist exclusively of `static` methods
+ (no instance properties, no instance methods, only static factories or utilities). Pair it
+ with `private function __construct() {}` to prevent instantiation. `readonly` is meaningless
+ without instance state, and the private constructor signals that the class is a static
+ surface, not a value type.
+- Inheritance between concrete classes is prohibited. Every concrete class is `final`.
+- Polymorphism uses interfaces plus composition, never extension of concrete types.
+- The only allowed `extends` is against framework or SPL base classes that the language requires.
+ Examples are `RuntimeException`, `LogicException`, `PHPUnit\Framework\TestCase`.
+- Constructors of `final` classes are `private` when paired with named factory methods, `public`
+ otherwise. `protected` constructors are prohibited because no subclasses exist to call them.
## Comparisons
-1. Null checks: use `is_null($variable)`, never `$variable === null`.
-2. Empty string checks on typed `string` parameters: use `$variable === ''`. Avoid `empty()` on typed strings
- because `empty('0')` returns `true`.
-3. Mixed or untyped checks (value may be `null`, empty string, `0`, or `false`): use `empty($variable)`.
+1. Null checks use `is_null($variable)`, never `$variable === null`.

+ typed strings because `empty('0')` returns `true`.
+3. Mixed or untyped checks (value may be `null`, empty string, `0`, or `false`) use
+ `empty($variable)`.
## American English
-All identifiers, enum values, comments, and error codes use American English spelling:
-`canceled` (not `cancelled`), `organization` (not `organisation`), `initialize` (not `initialise`),
-`behavior` (not `behaviour`), `modeling` (not `modelling`), `labeled` (not `labelled`),
-`fulfill` (not `fulfil`), `color` (not `colour`).
+All identifiers, enum values, comments, and error codes use American English spelling. Examples
+are `canceled` (not `cancelled`), `organization` (not `organisation`), `initialize` (not
+`initialise`), `behavior` (not `behaviour`), `modeling` (not `modelling`), `labeled` (not
+`labelled`), `fulfill` (not `fulfil`), `color` (not `colour`).
## PHPDoc
-- PHPDoc is restricted to interfaces only, documenting obligations, `@throws`, and complexity.
-- Never add PHPDoc to concrete classes.
+### When required
+
+- Every method of an interface.
+- Every public method of a concrete class outside `src/Internal/`. Public classes are at the
+ public API boundary by definition. Consumers call every public method directly, and the
+ PHPDoc is the contract for each call. Trivial getters and `with*` methods are not exempt.
+ The only exception is a public method whose contract is already documented on an implemented
+ interface (the interface carries the docblock).
+
+### When prohibited
+
+- Constructors. The constructor signature with property promotion is self-documenting. Parameter
+ types are already explicit in the signature.
+- Private and protected methods.
+- Public methods of concrete classes whose contract is already documented on an implemented
+ interface. The interface carries the docblock.
+- Anything inside `src/Internal/`. Internal types are implementation detail and must not carry
+ PHPDoc. The namespace itself is the boundary. See `php-library-architecture.md` for the
+ architectural meaning of `Internal/`.
+- Anywhere inside `tests/`. Test methods name the scenario via the `testXxxWhenYyyGivenThenZzz`
+ naming convention, and the `@Given`/`@When`/`@Then`/`@And` annotation blocks defined in
+ `php-library-testing.md` describe the steps. PHPDoc documentation (summary plus
+ `@param`/`@return` descriptions) is prohibited on test methods, data providers, fixtures,
+ setUp/tearDown overrides, and anonymous classes inside tests. The BDD annotations are not
+ PHPDoc documentation in the sense of this section and remain required per the testing rule.
+- Single-line PHPDocs with only a tag (`/** @param ... */`, `/** @return ... */`,
+ `/** @throws ... */`). PHPDoc always opens with a summary line. Bare-tag docblocks are
+ prohibited regardless of how few tags they carry.
+
+The prohibitions above apply to **every form of PHPDoc** in the prohibited scope:
+method-level docblocks, property-level docblocks, inline `@var` annotations on local variables,
+and PHPDoc blocks placed above anonymous functions or closures inside method bodies. Inside
+`src/Internal/` and `tests/`, zero PHPDoc is the rule with no exception. PHPStan errors that
+result from the missing annotations route through `ignoreErrors` (see below).
+
+The PHPDoc prohibitions above take priority over the typed-array case. When PHPStan at
+`level: max` flags a missing iterable value type (`missingType.iterableValue`,
+`argument.type`, `return.type`):
+
+- On a **constructor parameter** → suppress via `ignoreErrors` in `phpstan.neon.dist`. Do not
+ add PHPDoc.
+- On anything inside **`src/Internal/`** → suppress via `ignoreErrors`. Do not add PHPDoc.
+- On anything inside **`tests/`** → suppress via `ignoreErrors`. Do not add PHPDoc.
+- On a **public method of a public (non-Internal) class** → add full PHPDoc with summary,
+ `@param` descriptions, and the typed-array information. The bare-tag form remains
+ prohibited. This is the normal case where PHPDoc is permitted by "When required" above.
+
+The summary requirement and the bare-tag prohibition are never waived. Use `ignoreErrors` only
+when the context (constructor, `src/Internal/`, `tests/`) makes PHPDoc impossible. Every public
+method of a public concrete class carries PHPDoc per "When required", whether the method
+has typed-array parameters.
+
+### Style
+
+- Summary on the first line, in domain terms. **Mandatory.** PHPDoc without a summary line is
+ prohibited, even when it carries a single `@param` or `@return`.
+- Optional detailed body in `
` paragraphs below the summary.
+- Tags use the form `@param Type $name Description.`, `@return Type Description.`,
+ `@throws ExceptionClass If .`.
- Document `@throws` for every exception the method may raise.
-- Document time and space complexity in Big O form. When a method participates in a fused pipeline (e.g., collection
- pipelines), express cost as a two-part form: call-site cost + fused-pass contribution. Include a legend defining
- variables (e.g., `N` for input size, `K` for number of stages).
+- HTML tags allowed inside descriptions are `
` for paragraphs, `
` for lists,
+ `` for inline code, `` and `` for emphasis.
+
+### Summary patterns
+
+The summary line is not a creative intent statement. It is a template selected by the method's
+name prefix. Apply the matching template. Only methods with no matching prefix require a
+free-form one-line summary in domain terms.
+
+| Method shape | Template |
+|-------------------------------------------------------------------------|--------------------------------------------------------------------------------|
+| Static factory (`create`, `from`, `fromX`, `with*` when static) | `Creates a {ClassName} from {input}.` or `Builds a {ClassName} with {fields}.` |
+| `with*` instance method | `Returns a copy of the {ClassName} with the {field} replaced.` |
+| Getter (no prefix, returns a property: `code()`, `body()`, `headers()`) | `Returns the {field}.` |
+| Predicate (`is*`, `has*`, `can*`, `was*`, `should*`) | `Tells whether {condition}.` |
+| Converter (`toArray`, `toString`, `asX`) | `Returns the {ClassName} as {target shape}.` |
+| `apply*`, `merge*`, `add*`, and other side-effect-free operations | One-line summary in domain terms describing the operation. |
+
+The patterns are mandatory when applicable. They make summary lines mechanical: substitute
+`{ClassName}` and `{field}` and the summary is complete. No per-method intent decision is
+required. Volume is never a reason to skip the summary. Many methods just mean applying the
+template many times.
+
+### Cross-references
+
+- `{@see ClassName}` for links to other types in the codebase.
+- `@see Author, Title (Publisher, Year), Chapter X.` for bibliographical references.
+
+### Examples
+
+**Prohibited.** Single-line bare-tag PHPDoc, no summary:
+
+```php
+/** @param array|null $body */
+public static function with(Code $code, ?array $body = null): Response
+```
+
+**Prohibited.** PHPDoc on a constructor:
+
+```php
+/** @param array $entries */
+public function __construct(public array $entries)
+{
+}
+```
+
+**Prohibited.** PHPDoc on anything inside `src/Internal/`:
+
+```php
+namespace TinyBlocks\Http\Internal\Client;
+
+final readonly class Url
+{
+ /** @param array|null $query */
+ public static function compose(string $path, ?array $query, string $baseUrl): string
+ {
+ }
+}
+```
+
+**Correct.** Generic array type with summary and `@param` description:
+
+```php
+/**
+ * Builds a synthesized response from a status code and an optional body.
+ *
+ * @param array|null $body The response body as an associative array.
+ * @return Response The synthesized response instance.
+ */
+public static function with(Code $code, ?array $body = null): Response
+```
+
+**Correct.** Interface with rich description, paragraphs, cross-references, and bibliography:
+
+```php
+/**
+ * Money tied to a specific currency.
+ *
+ *
Operations between different currencies raise CurrencyMismatch. Arithmetic
+ * preserves the currency.
+ *
+ *
Sibling of {@see Quantity}, not a parent. Money carries currency semantics.
+ *
+ * @see Eric Evans, Domain-Driven Design (Addison-Wesley, 2003), Chapter 5.
+ */
+interface Money
+{
+ /**
+ * Adds the given amount.
+ *
+ * @param Money $other The amount to add.
+ * @return Money A new instance with the summed amount.
+ * @throws CurrencyMismatch If $other has a different currency.
+ */
+ public function add(Money $other): Money;
+}
+```
+
+**Correct.** Concrete class with a short summary and direct tags:
+
+```php
+/**
+ * IANA timezone identifier (e.g. America/Sao_Paulo).
+ */
+final readonly class Timezone
+{
+ /**
+ * Creates a Timezone from a valid IANA identifier.
+ *
+ * @param string $identifier The IANA timezone identifier.
+ * @return Timezone The created instance.
+ * @throws InvalidTimezone If the identifier is not a valid IANA timezone.
+ */
+ public static function from(string $identifier): Timezone
+ {
+ # ...
+ }
+}
+```
+
+## Dependencies
+
+When the library needs an external dependency, prefer packages from the `tiny-blocks` ecosystem
+(https://github.com/tiny-blocks) whenever a suitable option exists. Reach for outside packages
+only when the ecosystem has no equivalent that fits the use case.
## Collection usage
-When a property or parameter is `Collectible`, use its fluent API. Never break out to raw array functions such as
-`array_map`, `array_filter`, `iterator_to_array`, or `foreach` + accumulation. The same applies to `filter()`,
-`reduce()`, `each()`, and all other `Collectible` operations. Chain them fluently. Never materialize with
-`iterator_to_array` to then pass into a raw `array_*` function.

+**Correct.** Fluent chain with `map()` plus `toArray()`:
```php
$names = $collection
->map(transformations: static fn(Element $element): string => $element->name())
->toArray(keyPreservation: KeyPreservation::DISCARD);
```
+
+## Format strings
+
+When building a message with placeholders, assign the format string to a `$template` variable
+first. Pass it to `sprintf` on a separate statement. The format and the data are visually
+separated, and the template line stays scannable.
+
+**Prohibited.** Format string inline with the call:
+
+```php
+if ($value < 0 || $value > 16) {
+ throw new PrecisionOutOfRange(
+ message: sprintf('Precision must be between 0 and 16, got %d.', $value)
+ );
+}
+```
+
+**Correct.** Format string in a `$template` variable:
+
+```php
+if ($value < 0 || $value > 16) {
+ $template = 'Precision must be between 0 and 16, got %d.';
+
+ throw new PrecisionOutOfRange(message: sprintf($template, $value));
+}
+```
+
+## Constructor chaining
+
+PHP 8.4 allows chained method calls directly on a `new` expression without wrapping it in
+parentheses. The parentheses are no longer required and only add visual noise. Apply this
+everywhere a `new` is followed by a method call.
+
+**Prohibited.** Parentheses around the `new` expression:
+
+```php
+$body = (new ServerRequest(method: 'GET', uri: 'https://api.example.com'))
+ ->withHeader('Accept', 'application/json')
+ ->getBody();
+```
+
+**Correct.** No parentheses:
+
+```php
+$body = new ServerRequest(method: 'GET', uri: 'https://api.example.com')
+ ->withHeader('Accept', 'application/json')
+ ->getBody();
+```
+
+## Formatting overrides
+
+Three formatting rules are not covered by the canonical `phpcs.xml` (which references `PSR-12`
+only). Apply them manually.
+
+### No vertical alignment in parameter lists
+
+Use a single space between the type and the variable name in parameter lists (constructors,
+function signatures, closures). Never pad with extra spaces to align columns. This rule applies
+only to parameter lists, not to other contexts that use `=>` alignment (see "Vertical alignment
+of `=>`" below).
+
+**Prohibited.** Vertical alignment of types:
+
+```php
+public function __construct(
+ public OrderId $id,
+ public Money $total,
+ public Customer $customer,
+ public Precision $precision
+) {}
+```
+
+**Correct.** Single space between type and variable:
+
+```php
+public function __construct(
+ public OrderId $id,
+ public Money $total,
+ public Customer $customer,
+ public Precision $precision
+) {}
+```
+
+### Vertical alignment of `=>` in match arms and array literals
+
+Multi-line `match` expressions and multi-line array literals with `=>` align the `=>` column
+across all arms or entries by padding shorter left-hand sides with spaces. Single-line cases
+(one-arm match, single-line array) keep the standard PSR-12 single-space form.
+
+**Prohibited.** Unaligned `=>` in match:
+
+```php
+return match ($this) {
+ self::MAX_AGE => sprintf($template, $this->value, $value),
+ default => $this->value
+};
+```
+
+**Correct.** Aligned `=>` in match:
+
+```php
+return match ($this) {
+ self::MAX_AGE => sprintf($template, $this->value, $value),
+ default => $this->value
+};
+```
+
+**Prohibited.** Unaligned `=>` in array literal:
+
+```php
+return [
+ 'name' => 'Gustavo',
+ 'role' => 'developer',
+ 'company' => 'Anthropic'
+];
+```
+
+**Correct.** Aligned `=>` in array literal:
+
+```php
+return [
+ 'name' => 'Gustavo',
+ 'role' => 'developer',
+ 'company' => 'Anthropic'
+];
+```
+
+### No trailing comma in multi-line lists
+
+Never place a trailing comma after the last element of any multi-line list. Applies to parameter
+lists, argument lists, array literals, match arms, and every other comma-separated multi-line
+structure. PHP accepts trailing commas in these positions, but this ecosystem prohibits them for
+visual consistency.
+
+**Prohibited.** Trailing comma after the last argument:
+
+```php
+new Precision(
+ value: 2,
+ rounding: RoundingMode::HALF_UP,
+);
+```
+
+**Correct.** No trailing comma:
+
+```php
+new Precision(
+ value: 2,
+ rounding: RoundingMode::HALF_UP
+);
+```

+description: Conventional Commits format. Applied on request when generating commit messages.
+---
+
+# Commits
+
+Applied only when generating commit messages, never automatically. All commit messages are
+written in English.
+
+## Format
+
+`: `
+
+The description starts with a capital letter, uses imperative present tense ("Add", "Fix",
+"Change", not "Added", "Adds", or "Adding"), and ends with a period. Subject under 300
+characters. If it does not fit, split the change into multiple commits or move detail into the
+body.
+
+Scopes are prohibited. `feat(orders): ...` is wrong. The type stands alone.
+
+## Allowed types
+
+Each entry below is a bullet that starts with a capital letter and ends with a period. This is
+the canonical example of bullet punctuation enforced everywhere in this document.
+
+- `ci` for CI configuration changes.
+- `fix` for a bug fix.
+- `feat` for a user-facing feature.
+- `docs` for documentation only.
+- `test` for adding or correcting tests.
+- `chore` for maintenance with no production code change.
+- `build` for build or dependency changes.
+- `revert` for reverting a previous commit.
+- `refactor` for a code change that neither fixes a bug nor adds a feature.
+
+`style` is not used. Formatting is enforced by the linter and never appears as a standalone
+commit.
+
+## Subject examples
+
+Good:
+
+- `fix: Handle zero-amount transactions.`
+- `feat: Add order cancellation endpoint.`
+- `refactor: Extract OrderStatus into its own enum.`
+
+Bad:
+
+- `Added order cancellation` is past tense, missing type, missing period.
+- `feat: Adds order cancellation.` is third-person singular instead of imperative.
+- `feat: added order cancellation.` starts lowercase and is past tense.
+- `feat: Add cancellation, and fix billing rounding.` bundles two changes. Split.
+- `feat(orders): Add cancellation.` uses a scope. Prohibited.
+
+## Body
+
+The body is **optional and rarely needed**. Single-purpose commits never have a body. Add a body
+ONLY when the reason cannot be inferred from the diff (a non-obvious trade-off, a workaround for
+an external bug, a decision worth recording).
+
+Separate the body from the subject with a blank line. Wrap at 72 characters per line. Explain
+why, not what. The diff already shows what.
+
+## Prose vs. bullets in the body
+
+**Default to prose.** One or two paragraphs fits almost every commit that has a body at all.
+
+**Use bullets only when ALL of these are true:**
+
+1. The commit covers 3 or more independent changes that genuinely belong in the same commit.
+2. The list cannot be expressed as continuous prose without becoming disconnected sentences.
+3. Each item is independently meaningful (no sub-bullets, no continuation across bullets).
+
+A two-item bullet list is the wrong shape. Use prose.
+
+## Bullet formatting (when used)
+
+Every bullet starts with a capital letter and ends with a period. Imperative verb in present
+tense, same as the subject line. Without exception.
+
+Wrong (do NOT generate):
+
+- `add the OrderCancelling port` lowercase, missing period.
+- `Add the OrderCancelling port` capital but missing period.
+- `Adds the OrderCancelling port.` third-person singular instead of imperative.
+
+## Body example with bullets
+
+```
+feat: Add order cancellation flow.
+
+- Add the OrderCancelling inbound port and OrderCancellingHandler.
+- Add the CancelOrder command and its validator.
+- Cover the cancellation path in the integration test suite.
+```
+
+## Body example with prose (preferred for most commits)
+
+```
+fix: Handle zero-amount transactions.
+
+The payment gateway rejects zero-amount charges with a generic 400 instead
+of a documented error code, so the adapter short-circuits before the HTTP
+call and raises ZeroAmountNotAllowed directly.
+```
+
+## Commit splitting
+
+Prefer one logical change per commit. Refactor commits never modify behavior. When a task
+requires multiple types of change, produce multiple commits in order: `refactor` first, then
+`feat` or `fix` on top.

# Documentation
+Standards for `README.md` and other public-facing Markdown files in the repository. PHPDoc rules
+for `.php` files live in `php-library-code-style.md`. American English applies everywhere (see
+the American English section in `php-library-code-style.md`).
+
+The `CONTRIBUTING.md` file is centralized at
+`https://github.com/tiny-blocks/tiny-blocks/blob/main/CONTRIBUTING.md`. Each library's README and
+pull request template link to that location. No local `CONTRIBUTING.md` is created per library.
+
+## Pre-output checklist
+
+Verify every item before producing any Markdown documentation. If any item fails, revise before
+outputting.
+
+1. README title is `# ` with spaces between words (`# Building Blocks`, not
+ `# BuildingBlocks`).
+2. License badge is the only badge. No build, coverage, Packagist, or version badges.
+3. Header is followed by an anchor-linked table of contents.
+4. Table of contents uses `*` for top-level (H2) entries, `+` indented by 4 spaces for
+ second-level (H3) entries, and `-` indented by 8 spaces for third-level (H4) entries. Every
+ heading from the document appears in the TOC, except FAQ entries: the FAQ is represented by
+ a single `* [FAQ](#faq)` line regardless of how many questions it contains.
+5. Sections appear in the canonical order: Overview, Installation, How to use, FAQ (optional),
+ License, Contributing.
+6. FAQ exists only when there are genuine points of confusion or unusual design decisions. Skip
+ it entirely when not needed.
+7. **Self-contained code examples** are blocks that include any of: a `use` statement, a
+ `class`/`enum`/`interface`/`trait`/`function` declaration, or more than 3 lines of
+ executable code. Self-contained blocks open with `?` with zero-padded numbering
+ (`### 01.`, `### 02.`).
+12. FAQ bibliographic citations use the format
+ `> Author, *Title* (Publisher, Year), Chapter X, "Section Name".`
+13. License and Contributing sections each follow the canonical one-line template.
+14. Repository includes `SECURITY.md`, `.github/ISSUE_TEMPLATE/bug_report.md`,
+ `.github/ISSUE_TEMPLATE/feature_request.md`, and `.github/PULL_REQUEST_TEMPLATE.md`, each
+ matching the canonical template in "Other documentation files".
+
## README
-1. Include an anchor-linked table of contents.
-2. Start with a concise one-line description of what the library does.
-3. Include a **license** badge. Do not include any other badges.
-4. Provide an **Overview** section explaining the problem the library solves and its design philosophy.
-5. **Installation** section: Composer command (`composer require vendor/package`).
-6. **How to use** section: complete, runnable code examples covering the primary use cases. Each example
- includes a brief heading describing what it demonstrates.
-7. If the library exposes multiple entry points, strategies, or container types, document each with its own
- subsection and example.
-8. **FAQ** section: include entries for common pitfalls, non-obvious behaviors, or design decisions that users
- frequently ask about. Each entry is a numbered question as heading (e.g., `### 01. Why does X happen?`)
- followed by a concise explanation. Only include entries that address real confusion points.
-9. **License** and **Contributing** sections at the end.
-10. Write strictly in American English. See `php-library-code-style.md` American English section for spelling
- conventions.
+### Structure
+
+The README follows a fixed section order:
+
+1. **Overview**. One or more paragraphs explaining the problem the library solves and its design
+ philosophy. Cross-references to related `tiny-blocks` libraries belong here.
+2. **Installation**. Composer command in a code block, with no surrounding prose unless strictly
+ necessary.
+3. **How to use**. Runnable examples covering the primary use cases. Each subsection demonstrates
+ one capability with a heading and a self-contained code block.
+4. **FAQ** (optional). Numbered questions that address real points of confusion or unusual design
+ decisions.
+5. **License**. One-line link to the `LICENSE` file.
+6. **Contributing**. One-line link to the centralized `CONTRIBUTING.md` in
+ `tiny-blocks/tiny-blocks`.
+
+### Header and license badge
+
+The first line is `# ` followed by a blank line and the license badge:

+
+### Table of contents
+
+The table of contents is anchor-linked. Top-level (H2) entries use `*`. Second-level (H3)
+entries use `+` indented by 4 spaces. Third-level (H4) entries use `-` indented by 8 spaces.
+Every heading from the document appears, with one exception: the FAQ is represented by a single
+`* [FAQ](#faq)` line. Its questions never appear as TOC sub-entries, regardless of how many
+exist.
+
+```markdown
+* [Overview](#overview)
+* [Installation](#installation)
+* [How to use](#how-to-use)
+ + [Subtopic A](#subtopic-a)
+ + [Subtopic B](#subtopic-b)
+* [FAQ](#faq)
+* [License](#license)
+* [Contributing](#contributing)
+```
+
+Use the third level whenever the document has H4 headings, regardless of whether they form a
+two-axis split. The TOC mirrors the document structure exactly.
+
+```markdown
+* [How to use](#how-to-use)
+ + [Entity](#entity)
+ - [Single-field identity](#single-field-identity)
+ - [Compound identity](#compound-identity)
+ + [Aggregate](#aggregate)
+```
+
+### Code examples
+
+Code examples fall into two categories.
+
+**Self-contained examples** include at least one of:
+
+- A `use` statement.
+- A `class`, `enum`, `interface`, `trait`, or `function` declaration.
+- More than 3 lines of executable code.
+
+They open with `push(records: $order->recordedEvents());
+```
+
+**Inline fragment examples** have all of:
+
+- At most 3 lines of executable code.
+- No `use` statements.
+- No type declarations.
+
+Fragments may omit the prologue.
+
+```php
+Code::OK->value;
+```
+
+The criteria are mechanical: a block that meets any self-contained condition gets the prologue. A block that meets every fragment condition may omit it. There is no middle ground.
+
+The `#` convention for inline comments applies only to code examples inside Markdown files. PHP
+files under `src/` and `tests/` have no inline comments at all, except `# TODO: ` (see
+item 16 in `php-library-code-style.md`).
+
+### FAQ
+
+FAQ entries are numbered with zero-padded prefixes and end with a question mark:
+
+```markdown
+### 01. Why is DomainEvent close to a marker interface?
+
+A domain event is a fact about something that happened in the domain. The contract carries only
+`revision()` so the library can route schema migrations through upcasters. Everything else
+(aggregate identity, sequence number, aggregate type, occurrence timestamp) is envelope metadata
+that belongs to `EventRecord`.
+
+> Vaughn Vernon, *Implementing Domain-Driven Design* (Addison-Wesley, 2013), Chapter 8,
+> "Domain Events".
+```
+
+Bibliographic citations follow the format
+`> Author, *Title* (Publisher, Year), Chapter X, "Section Name".` The chapter and section
+fragments are optional when the title is precise enough on its own. Multiple citations can be
+stacked as separate blockquote lines.
+
+### License and Contributing
+
+The License section is a single line:
+
+```markdown
+## License
+
+ is licensed under [MIT](LICENSE).
+```
+
+The Contributing section is a single line pointing to the centralized guideline:
+
+```markdown
+## Contributing
+
+Please follow the [contributing guidelines](https://github.com/tiny-blocks/tiny-blocks/blob/main/CONTRIBUTING.md) to
+contribute to the project.
+```
## Structured data
-1. When documenting constructors, factory methods, or configuration options with more than 3 parameters,
- use tables with columns: Parameter, Type, Required, Description.
-2. Prefer tables to prose for any structured information.
+Tables are preferred to prose for any structured information: constructor parameter lists,
+builder method catalogs, default value tables, complexity tables, and configuration matrices.
+Column layout is chosen per case. No fixed column set is mandated.
+
+## Other documentation files
+
+Every library repository includes the following files in addition to the README. Each follows
+the canonical template below.
+
+### SECURITY.md
+
+```markdown
+# Security Policy

+description: Structure, ordering, and pinning rules for GitHub Actions workflows in PHP libraries.
+paths:
+ - ".github/workflows/**/*.yml"
+ - ".github/workflows/**/*.yaml"
+---
+
+# Workflows
+
+Conventions for GitHub Actions workflows in PHP libraries. CD does not apply. Libraries publish
+to Packagist via tags and never deploy.
+
+`.github/workflows/ci.yml` is mandatory and follows the canonical structure defined in the
+"ci.yml" section below. Additional workflow files (security scanning, automated triage,
+scheduled tasks, dependency updates, etc.) may exist and follow the general rules in this file.
+Their trigger, job structure, and steps are chosen by their purpose.
+
+The Composer scripts invoked by `ci.yml` (`composer review`, `composer tests`) are defined in
+`php-library-tooling.md`.
+
+## Pre-output checklist
+
+Verify every item before producing or editing any workflow YAML. If any item fails, revise
+before outputting.
+
+### Rules for every workflow
+
+These rules apply to `ci.yml` and to every additional workflow in `.github/workflows/`.
+
+1. Keys at the workflow root follow the canonical order `name`, `on`, `concurrency`,
+ `permissions`, `jobs`. Keys absent in a given workflow are simply omitted. The relative order
+ of the remaining keys is preserved.
+2. Properties inside a job follow the canonical order `name`, `needs`, `runs-on`,
+ `timeout-minutes`, `outputs`, `env`, `steps`. Same omission rule as above.
+3. Inside any block (`env`, `outputs`, `with`, `permissions`), entries are ordered by key length
+ ascending.
+4. The workflow `name`, every job `name`, and every step `name` are mandatory and use sentence
+ case (`Resolve PHP version`, not `RESOLVE_PHP_VERSION` or `resolve_php_version`). Step names
+ start with a verb. Job keys describe the job's purpose. Generic keys (`run`, `job`, `do`) are
+ discouraged in favor of descriptive identifiers (`auto-assign`, `analyze`, `notify`).
+5. `concurrency` is set at the workflow root with `cancel-in-progress: true` and a `group`
+ expression scoped by the workflow's trigger:
+ - `pull_request`: `-${{ github.event.pull_request.number }}`.
+ - `issues`, or `issues` combined with `pull_request`:
+ `-${{ github.event.issue.number || github.event.pull_request.number }}`.
+ - `push`, `schedule`, or both: `-${{ github.ref }}`.
+
+ `` is the workflow's short name (`ci`, `codeql`, `auto-assign`).
+6. `permissions` is declared at the workflow root with the minimum scope every job needs.
+ Job-level `permissions` blocks are allowed only when a specific job needs a narrower scope
+ than the root, never broader.
+7. Every job sets `timeout-minutes`. Defaults: 5 for trivial steps (single API call, lightweight
+ script), 15 for jobs with PHP setup or test runs, 30 for analysis-heavy jobs (CodeQL,
+ security scanning). Adjust based on observed runtime when prior runs exist.
+8. Every action is pinned to a fixed major version tag written explicitly. Examples are
+ `actions/checkout@v6` and `shivammathur/setup-php@v2`. Never use `@latest`, `@main`, a branch
+ name, or a commit SHA. When the existing pin is an explicit minor or patch, derive the major
+ version while **preserving the prefix style** of the original tag: `@v2.1.0` → `@v2`,
+ `@2.1.0` → `@2`. The action's tag convention is reflected in the existing pin. Web lookup is
+ required only when the existing pin is missing, ambiguous, or pointing to a non-version
+ reference. Example versions cited in this file may be outdated and are not a license to skip
+ the lookup when it is required.
+9. Inline shell logic longer than 3 lines is extracted to a script in `scripts/ci/`.
+10. All text (workflow name, job names, step names, comments) uses American English with correct
+ spelling and punctuation. Sentences and descriptions end with a period.
+
+### Rules specific to ci.yml
+
+These rules apply only to `.github/workflows/ci.yml`. Additional workflows are not bound by them.
+
+1. File path is `.github/workflows/ci.yml`. The workflow `name` field is exactly `CI`.
+2. Trigger is `pull_request` only. No `push`, no branch filter, no `workflow_dispatch`.
+3. Jobs run in the fixed sequence `resolve-php-version`, `build`, `auto-review`, `tests`. Each
+ downstream job lists its upstream jobs in `needs`.
+4. PHP version is never hardcoded. The `resolve-php-version` job reads `.require.php` from
+ `composer.json` at runtime and exposes the minor version (for example, `8.5`) as the job
+ output `php-version`. Downstream jobs reference
+ `${{ needs.resolve-php-version.outputs.php-version }}` when setting up PHP.
+5. The `auto-review` job runs `composer review`. The `tests` job runs `composer tests`. Both
+ scripts are defined in `composer.json` per `php-library-tooling.md`. No other command is
+ invoked in either job.
+6. The `build` job uploads `vendor/` and `composer.lock` as a single artifact named
+ `vendor-artifact`. The `auto-review` and `tests` jobs download that artifact instead of
+ running `composer install` again.
+7. The `tests` job is the only job that may extend with extra setup required by the library,
+ such as service containers, fixture preparation, or environment variables used during
+ testing. The other three jobs are identical across every library in the ecosystem.
+8. `concurrency.group` is `pr-${{ github.event.pull_request.number }}`. `timeout-minutes` is 5
+ for `resolve-php-version` and 15 for `build`, `auto-review`, and `tests`. `permissions` is
+ `contents: read`.
+
+## ci.yml
+
+`ci.yml` is the mandatory workflow that gates every pull request. It contains four jobs in the
+exact order below. The first three jobs are identical across every library. Only `tests` may
+extend with extra setup required by the library.
+
+### Resolve PHP version
+
+Reads `.require.php` from `composer.json` and exposes the minor version (for example, `8.5`) as the
+output `php-version`. A single step uses `jq` and a short regex to extract the value. Downstream jobs
+consume the output to configure their PHP setup.
+
+### Build
+
+Sets up PHP using the resolved version, validates `composer.json`, installs dependencies with
+`--no-progress --optimize-autoloader --prefer-dist --no-interaction`, and uploads `vendor/` and
+`composer.lock` as the artifact `vendor-artifact`.
+
+### Auto review
+
+Depends on `resolve-php-version` and `build`. Downloads `vendor-artifact`, sets up PHP, and runs
+`composer review`. The `review` script in `composer.json` aggregates lint, static analysis, and style
+checks for the library.
+
+### Tests
+
+Depends on `resolve-php-version` and `auto-review`. Downloads `vendor-artifact`, sets up PHP, and runs
+`composer tests`. Any setup required by the library's tests (service containers, fixture preparation,
+environment variables used during testing) lives in this job only.
+
+## Reference shape
+
+The YAML below is the canonical minimal form. Every library starts from this exact shape and extends
+only the `tests` job when its tests require extra setup. Action versions cited here may be outdated.
+Look up the current major version of every action via web search before adopting this shape verbatim.
+
+### Minimal workflow
+
+```yaml

+
+### Extending the tests job
+
+When the library's tests need external services, env vars, or fixture preparation, the additions live
+inside the `tests` job only. The example below shows the same `tests` job extended with a MySQL service
+container and the env vars consumed by the test suite.
+
+```yaml
+tests:
+ name: Tests

-# Library modeling
+# Modeling
+
+Library modeling rules. How to model the concepts the library exposes. Folder structure and
+public API boundary live in `php-library-architecture.md`. Code style lives in
+`php-library-code-style.md`. Tooling lives in `php-library-tooling.md`.
+
+## Pre-output checklist
+
+Verify every item before producing any PHP code that defines a model, an exception, or an
+algorithm. If any item fails, revise before outputting.
+
+1. Each model has a single, clear responsibility. Apply DDD, SOLID, DRY, and KISS where they
+ sharpen the design, not as dogma.
+2. Concept names. Every class, property, method, and exception name reflects the concept the
+ library represents, not a technical role.
+3. No always-banned names. Never use `Data`, `Info`, `Utils`, `Item`, `Record`, `Entity` as
+ class suffix, prefix, or method name. Never use `Exception` as a class suffix. Exception:
+ names that correspond to externally standardized identifiers (HTTP status text from RFC
+ documents, PSR interface names being mirrored, etc.) are permitted. The standard reference
+ is the meaning carrier.
+4. No anemic verbs as the primary operation name (`ensure`, `validate`, `check`, `verify`,
+ `assert`, `mark`, `enforce`, `sanitize`, `normalize`, `compute`, `transform`, `parse`) unless
+ the verb is the library's reason to exist.
+5. Architectural role names (`Manager`, `Handler`, `Processor`, `Service`, and their verb forms
+ `process`, `handle`, `execute`) are allowed only when the class IS that role for consumers
+ integrating with the library.
+6. Value objects are immutable. No setters. Operations return new instances.
+7. Value objects compare by value, never by reference. No identity field.
+8. Value objects validate invariants in the constructor and throw a dedicated exception on
+ invalid input.
+9. Value objects with multiple creation paths use static factory methods (`from`, `of`, `zero`)
+ with a private constructor.
+10. Every failure throws a dedicated exception class named after the invariant it guards. Never
+ `throw new DomainException(...)`, `throw new InvalidArgumentException(...)`, or any other
+ generic native exception directly.
+11. Dedicated exception classes extend the appropriate native PHP exception (`DomainException`,
+ `InvalidArgumentException`, `OverflowException`, etc.).
+12. Exceptions are pure. No transport-specific fields (HTTP status in `code`, formatted message
+ for end-user display). They signal invariant violations only, never control flow.
+13. Enums are PHP backed enums. They include methods only when those methods carry vocabulary
+ meaning.
+14. Extension points use `class` instead of `final readonly class`. They expose a private
+ constructor with static factory methods as the only creation path. Internal state is
+ injected via the constructor.
+15. Algorithms run in O(N) or O(N log N) unless the problem inherently requires worse. O(N²)
+ or worse needs explicit justification.
+16. Prefer lazy or streaming evaluation over materializing intermediate results. Memory usage
+ is bounded and proportional to the output, not to the sum of intermediate stages.
+
+## Modeling principles
+
+Apply the following principles where they sharpen the design. Treat them as guides, not as dogma.
+
+- Single responsibility. Each model represents one concept, has one reason to change, and
+ exposes operations that belong to that concept.
+- DDD ubiquitous language. Names, types, and operations match the vocabulary the library's
+ domain uses. Code and conversation share the same terms.
+- SOLID. Interfaces define narrow contracts. Composition is preferred to inheritance.
+ Substitutability holds at every interface boundary.
+- DRY. No duplicated logic across two or more places.
+- KISS. No abstraction without real duplication or isolation need.
-Libraries are self-contained packages. The core has no dependency on frameworks, databases, or I/O. Refer to
-`php-library-code-style.md` for the pre-output checklist applied to all PHP code.
+## Nomenclature
-## Folder structure
+- Every class, property, method, and exception name reflects the concept the library represents.
+ A math library uses `Precision` and `RoundingMode`. A money library uses `Currency` and
+ `Amount`. A collection library uses `Collectible` and `Order`.
+- Name classes after what they represent, not after what they do technically. Use `Money`,
+ `Color`, `Pipeline`, not `MoneyCalculator`, `ColorHelper`, `PipelineProcessor`.
+- Name methods after the operation in the library's vocabulary. Use `add()`, `convertTo()`,
+ `splitAt()`, not `compute()`, `process()`, `handle()`.
-```
-src/
-├── .php # Primary contract for consumers
-├── .php # Main implementation or extension point

-├── Internal/ # Implementation details (not part of public API)
-│ ├── .php
-│ └── Exceptions/ # Internal exception classes
-├── / # Feature-specific subdirectory when needed
-└── Exceptions/ # Public exception classes (when part of the API)
-```
+### Always banned
-Never use `Models/`, `Entities/`, `ValueObjects/`, `Enums/`, or `Domain/` as folder names.
+These names carry zero semantic content. Never use them anywhere as class suffix, prefix, or
+method name.
-## Public API boundary
+- `Data`, `Info`, `Utils`, `Item`, `Record`, `Entity`.
+- `Exception` as a class suffix (e.g., `FooException`). Use the invariant name when extending a
+ native exception (e.g., `PrecisionOutOfRange`, not `InvalidPrecisionException`).
-Only interfaces, extension points, enums, and thin orchestration classes live at the `src/` root. These classes
-define the contract consumers interact with and delegate all real work to collaborators inside `src/Internal/`.
-If a class contains substantial logic (algorithms, state machines, I/O), it belongs in `Internal/`, not at the root.
+### Externally standardized names (exception to the banlist)
-The `Internal/` namespace signals classes that are implementation details. Consumers must not depend on them.
-Breaking changes inside `Internal/` are not semver-breaking for the library.
+Names that correspond to externally standardized identifiers are exempt from the banlist. The
+standard reference is the meaning carrier. Renaming weakens it. Examples:
-## Nomenclature
+- HTTP status text from RFC documents (`unprocessableEntity` from RFC 4918, `noContent`).
+- PSR interface names being mirrored as test doubles (`ClientException` mirroring
+ `Psr\Http\Client\ClientExceptionInterface`).
+- Unicode category names, locale identifiers, MIME type tokens, and similar registered names.
-1. Every class, property, method, and exception name reflects the **concept** the library represents. A math library
- uses `Precision`, `RoundingMode`; a money library uses `Currency`, `Amount`; a collection library uses
- `Collectible`, `Order`.
-2. Name classes after what they represent: `Money`, `Color`, `Pipeline` — not after what they do technically.
-3. Name methods after the operation in the library's vocabulary: `add()`, `convertTo()`, `splitAt()`.
+This exception applies only when the external standard is the actual source of the name. It
+does not authorize using `Data` or `Entity` as generic suffixes when no external reference is
+involved.
-### Always banned
+### Anemic verbs
-These names carry zero semantic content. Never use them anywhere, as class suffixes, prefixes, or method names:
+These verbs hide what is actually happening behind a generic action. Banned unless the verb IS
+the operation that constitutes the library's reason to exist (e.g., a JSON parser may have
+`parse()`, a hashing library may have `compute()`).
-- `Data`, `Info`, `Utils`, `Item`, `Record`, `Entity`.
-- `Exception` as a class suffix (e.g., `FooException` — use `Foo` when it already extends a native exception).
+- `ensure`, `validate`, `check`, `verify`, `assert`, `mark`, `enforce`, `sanitize`, `normalize`,
+ `compute`, `transform`, `parse`.
-### Anemic verbs (banned by default)
+When in doubt, prefer the domain operation name. `Password::hash()` beats `Password::compute()`.
+`Email::parse()` is fine in a parser library but suspicious elsewhere. Use `Email::from()`
+instead.
-These verbs hide what is actually happening behind a generic action. Banned unless the verb **is** the operation
-that constitutes the library's reason to exist (e.g., a JSON parser may have `parse()`; a hashing library may
-have `compute()`):
+### Architectural roles
-- `ensure`, `validate`, `check`, `verify`, `assert`, `mark`, `enforce`, `sanitize`, `normalize`, `compute`,
- `transform`, `parse`.
+These names describe a role the library offers as a building block. Acceptable when the class IS
+that role (e.g., `EventHandler` in an events library, `CacheManager` in a cache library,
+`Upcaster` in an event-sourcing library). Not acceptable on domain objects inside the library
+(value objects, enums, contract interfaces).
-When in doubt, prefer the domain operation name. `Password::hash()` beats `Password::compute()`; `Email::parse()`
-is fine in a parser library but suspicious elsewhere (use `Email::from()` instead).
+- `Manager`, `Handler`, `Processor`, `Service`.
+- Verb forms: `process`, `handle`, `execute`.
-### Architectural roles (allowed with justification)
+The test. If the consumer instantiates or extends this class to integrate with the library, the
+role name is legitimate. If the class models a concept the consumer manipulates (a money amount,
+a country code, a color), the role name is wrong.
-These names describe a role the library offers as a building block. Acceptable when the class **is** that role
-(e.g., `EventHandler` in an events library, `CacheManager` in a cache library, `Upcaster` in an event-sourcing

## Exceptions
-1. Every failure throws a **dedicated exception class** named after the invariant it guards — never
- `throw new DomainException('...')`, `throw new InvalidArgumentException('...')`,
- `throw new RuntimeException('...')`, or any other generic native exception thrown directly. If the invariant
- is worth throwing for, it is worth a named class.
-2. Dedicated exception classes **extend** the appropriate native PHP exception (`DomainException`,
- `InvalidArgumentException`, `OverflowException`, etc.) — the native class is the parent, never the thing that
- is thrown. Consumers that catch the broad standard types continue to work; consumers that need precise handling
- can catch the specific classes.
-3. Exceptions are pure: no transport-specific fields (`code` populated with HTTP status, formatted `message` meant
- for end-user display). Formatting to any transport happens at the consumer's boundary, not inside the library.
-4. Exceptions signal invariant violations only, not control flow.
-5. Name the class after the invariant violated, never after the technical type:
- - `PrecisionOutOfRange` — not `InvalidPrecisionException`.
- - `CurrencyMismatch` — not `BadCurrencyException`.
- - `ContainerWaitTimeout` — not `TimeoutException`.
-6. A descriptive `message` argument is allowed and encouraged when it carries **debugging context** — the violating
- value, the boundary that was crossed, the state the library was in. The class name identifies the invariant;
- the message describes the specific violation for stack traces and test assertions. Do not build messages meant
- for end-user display or transport rendering. Keep them short, factual, and in American English.
-7. Public exceptions live in `src/Exceptions/`. Internal exceptions live in `src/Internal/Exceptions/`.

## Time and space complexity
-1. Every public method has predictable, documented complexity. Document Big O in PHPDoc on the interface
- (see `php-library-code-style.md`, "PHPDoc" section).
-2. Algorithms run in `O(N)` or `O(N log N)` unless the problem inherently requires worse. `O(N²)` or worse must
- be justified and documented.
-3. Prefer lazy/streaming evaluation over materializing intermediate results. In pipeline-style libraries, fuse
- stages so a single pass suffices.
-4. Memory usage is bounded and proportional to the output, not to the sum of intermediate stages.
-5. Validate complexity claims with benchmarks against a reference implementation when optimizing critical paths.
- Parity testing against the reference library is the validation standard for optimization work.
+- Algorithms run in O(N) or O(N log N) unless the problem inherently requires worse. O(N²) or
+ worse needs explicit justification at the point of definition.
+- Prefer lazy or streaming evaluation over materializing intermediate results. In pipeline-style
+ libraries, fuse stages so a single pass suffices over the input.
+- Memory usage is bounded and proportional to the output, not to the sum of intermediate stages.

+$paidTotals = array_map(
+ static fn(Order $order): float => $order->total(),
+ array_filter(
+ $orders->toArray(),
+ static fn(Order $order): bool => $order->isPaid()
+ )
+);
+```
+
+Each stage allocates a full intermediate array. Memory grows with the input size, even when only
+the final scalar matters.
+
+**Correct.** Fused pipeline that runs in a single pass:
+
+```php
+$paidTotals = $orders
+ ->filter(predicates: static fn(Order $order): bool => $order->isPaid())
+ ->map(transformations: static fn(Order $order): float => $order->total())
+ ->toArray(keyPreservation: KeyPreservation::DISCARD);
+```
+
+Operations stack on the same iterator. No intermediate array is built. Memory stays bounded by
+the final output.

+PHPUnit conventions for tests in PHP libraries. Covers BDD structure, fixture rules, and coverage
+discipline. Code style applies to test files as well. See `php-library-code-style.md`. Folder
+structure for `tests/` lives in `php-library-architecture.md`. Canonical thresholds (MSI 100,
+covered MSI 100) live in `php-library-tooling.md`.
+
+## Pre-output checklist
+
+Verify every item before producing any test code. If any item fails, revise before outputting.
+
+1. Each test contains exactly one `@When` block. Two actions require two tests.
+2. Use `@And` for complementary preconditions or actions within the same scenario, avoiding
+ consecutive `@Given` or `@When` tags.
+3. Each `@Given` or `@And` block contains exactly one annotation line followed by one expression
+ or assignment. Never place multiple variable declarations or object constructions under a
+ single annotation. **Exception for data-provider tests.** When the test method binds its
+ inputs through a `#[DataProvider]` attribute (or the equivalent `@dataProvider` annotation),
+ the `@Given` block may declare the input shape in prose form, without an expression below
+ it. The values are bound by PHPUnit before the test body runs, so the prose annotation
+ replaces the assignment that would otherwise sit under the `@Given`.
+
+ `@When` blocks follow the same one-expression rule by default: the block represents the
+ single action under test. **Exception for repeated-invocation tests** (idempotence, caching,
+ memoization). When the purpose of the test is asserting that the same operation produces the
+ same outcome across N invocations, the `@When` block may contain N consecutive identical
+ invocations, each captured in a numbered variable (`$first`, `$second`, ...), and the
+ annotation reads `@When invoked twice` (or thrice, etc.) to make the composite-action
+ semantic explicit. Two unrelated actions still require two tests.
+4. No intermediate variables used only once. Chain method calls when the intermediate state is
+ not referenced elsewhere (e.g., `Money::of(...)->add(...)` instead of
+ `$money = Money::of(...)` followed by `$money->add(...)`).
+5. No private or helper methods in test classes. The only non-test methods allowed are data
+ providers. Setup logic complex enough to extract belongs in a dedicated fixture class.
+6. Test only the public API. Never assert on private state or `Internal/` classes directly.
+7. Test the behavior that **raises** an exception, never the exception itself. Exception classes
+ represent invariant violations and are value objects, not the subject of behavior tests. A
+ test constructs the conditions, invokes the public method that is supposed to fail, and
+ asserts the expected exception class is raised (plus its accessor values when they carry
+ information relevant to the failure). Constructing an exception directly
+ (`new HttpRequestInvalid(...)`) and asserting on its accessors is **prohibited**: the
+ exception's structure is exercised through the call path that produces it. If a method does
+ not exist whose call path produces the exception, the exception is dead code and should be
+ removed.
+8. Never mock internal collaborators. Use real objects. Test doubles are used only at system
+ boundaries (filesystem, clock, network) when the library interacts with external resources.
+9. Name tests after behavior, not method names.
+10. Use domain-specific names in variables and properties. Never `$spy`, `$mock`, `$stub`,
+ `$fake`, `$dummy` as variable or property names. Use the domain concept the object
+ represents (`$collection`, `$amount`, `$currency`, `$sortedElements`). Class names like
+ `ClientMock` or `GatewaySpy` are acceptable. The variable holding the instance is what matters.
+11. Annotations use domain language. Write `/** @Given a collection of amounts */`, not
+ `/** @Given a mocked collection in test state */`.
+12. Never use the `/** @test */` annotation. Test methods are discovered by the `test` prefix in
+ the method name.
+13. Never use named arguments on PHPUnit assertions (`assertEquals`, `assertSame`, `assertTrue`,
+ `expectException`, etc.). Pass arguments positionally.
+14. Never include conditional logic inside tests. Each `@Then` block expresses one logical
+ concept. The only allowed `try`/`catch` is when the assertion target is a property of the
+ caught exception that cannot be expressed via `expectException*` methods (notably
+ `getPrevious()` for chain inspection). The catch block contains only assertions against the
+ caught exception, no branching.
+15. Never use `@codeCoverageIgnore`, attributes, or configuration that exclude code from
+ coverage. Never suppress mutants via `infection.json.dist` or any other mechanism. See
+ "Coverage and mutation discipline".

+
+## Testing exceptions
+
+Exception classes are value objects describing an invariant violation. They are not the subject
+of behavior tests. A test verifies that a public method, under specific conditions, raises a
+specific exception. Constructing the exception directly and asserting on its accessors is
+prohibited. The exception's structure is exercised through the call path that produces it.
+
+**Prohibited.** Testing the exception as a value object:
+
+```php
+public function testFromWhenAllFieldsGivenThenExposesEveryAccessor(): void
+{
+ /** @Given a URL */
+ $url = 'https://api.example.com';
+
+ /** @And an HTTP method */
+ $method = Method::GET;
+
+ /** @And a reason */
+ $reason = 'Connection refused.';
+
+ /** @When the exception is constructed */
+ $exception = HttpNetworkFailed::from(url: $url, method: $method, reason: $reason);
+
+ /** @Then it exposes the URL */
+ self::assertSame($url, $exception->url());
+}
+```
+
+The test constructs the exception in isolation and asserts on its accessors. No production code
+is exercised. The same coverage is achieved (and made meaningful) by the test below, which
+drives the path that raises the exception.
+
+**Correct.** Testing the behavior that raises the exception:
+
+```php
+public function testSendRequestWhenTransportCannotReachServerThenThrowsHttpNetworkFailed(): void
+{
+ /** @Given an HTTP client backed by a transport that always raises a network error */
+ $http = Http::usingTransport(transport: new ThrowingClient());
+
+ /** @And a target request to that transport */
+ $request = Request::create(url: 'https://api.example.com', method: Method::GET);
+
+ /** @Then a network failure exception describing the unreachable target is raised */
+ $this->expectException(HttpNetworkFailed::class);
+
+ /** @When the request is sent */
+ $http->send(request: $request);
+}
+```
+
+When the accessor values on the raised exception are part of the assertion, `expectException`
+alone is not enough (it asserts only the class). Use a `try`/`catch` block as permitted by
+rule 14. The catch block contains only assertions against the caught exception, no branching.
+
+```php
+public function testSendRequestWhenTargetUnreachableThenExceptionCarriesUrlAndMethod(): void
+{
+ /** @Given an HTTP client backed by a transport that always raises a network error */
+ $http = Http::usingTransport(transport: new ThrowingClient());
+
+ /** @And a target request to that transport */
+ $request = Request::create(url: 'https://api.example.com', method: Method::GET);
+
+ try {
+ /** @When the request is sent */
+ $http->send(request: $request);
+ } catch (HttpNetworkFailed $failure) {
+ /** @Then the exception exposes the target URL and method */
+ self::assertSame('https://api.example.com', $failure->url());
+ self::assertSame(Method::GET, $failure->method());
+ }
+}
+```
+
+If a method does not exist whose call path produces the exception, the exception itself is dead
+code. Remove it instead of writing a behavior test against a constructor.
+
+**The `try`/`catch` form is reserved for assertions that PHPUnit's `expectException*` family
+does not cover.** Message, code, and class are covered by PHPUnit (`expectException`,
+`expectExceptionMessage`, `expectExceptionMessageMatches`, `expectExceptionCode`): use those
+methods, not `try`/`catch`. The only case that warrants `try`/`catch` is inspecting accessors
+that PHPUnit cannot reach — notably `getPrevious()` for chain inspection, or domain-specific
+accessors on a `TransportFailure` (`url()`, `method()`, `reason()`).
+
+**Prohibited.** `try`/`catch` to assert message:
+
+```php
+try {
+ $http->send(request: $request);
+ self::fail('NoMoreResponses was expected.');
+} catch (NoMoreResponses $exception) {
+ self::assertStringContainsString('queue exhausted', $exception->getMessage());
+}
+```
+
+**Correct.** PHPUnit's `expectExceptionMessage`:
+
+```php
+$this->expectException(NoMoreResponses::class);
+$this->expectExceptionMessage('queue exhausted');
+
+$http->send(request: $request);
+```
## Test setup and fixtures
-1. **One annotation = one statement.** Each `@Given` or `@And` block contains exactly one annotation line
- followed by one expression or assignment. Never place multiple variable declarations or object
- constructions under a single annotation.
-2. **No intermediate variables used only once.** If a value is consumed in a single place, inline it at the
- call site. Chain method calls when the intermediate state is not referenced elsewhere
- (e.g., `Money::of(...)->add(...)` instead of `$money = Money::of(...); $money->add(...);`).
-3. **No private or helper methods in test classes.** The only non-test methods allowed are data providers.
- If setup logic is complex enough to extract, it belongs in a dedicated fixture class, not in a
- private method on the test class.
-4. **Domain terms in variables and annotations.** Never use technical testing jargon (`$spy`, `$mock`,
- `$stub`, `$fake`, `$dummy`) as variable or property names. Use the domain concept the object
- represents: `$collection`, `$amount`, `$currency`, `$sortedElements`. Class names like
- `ClientMock` or `GatewaySpy` are acceptable — the variable holding the instance is what matters.
-5. **Annotations use domain language.** Write `/** @Given a collection of amounts */`, not
- `/** @Given a mocked collection in test state */`. The annotation describes the domain
- scenario, not the technical setup.
-
-## Test organization
+- Each `@Given` or `@And` block contains exactly one annotation followed by one expression or
+ assignment. Never place multiple declarations under a single annotation. The exception for
+ data-provider tests applies here as well (see rule 3).

+```php
+/** @And two money instances in different currencies */
+$usd = Money::of(amount: 500, currency: Currency::USD);
+$eur = Money::of(amount: 300, currency: Currency::EUR);
+```
+
+**Correct.** One annotation per declaration:
+```php
+/** @And a money instance in USD */
+$usd = Money::of(amount: 500, currency: Currency::USD);
+
+/** @And a money instance in EUR */
+$eur = Money::of(amount: 300, currency: Currency::EUR);

+action: the input preparation goes back to `@And` under `@Given`, and `@When` contains only
+the action under test.
+

+## Test doubles
+
+Conventions for naming and locating test doubles (mocks, spies, stubs, fakes, dummies).
+
+### Naming
+
+- Variables and properties never carry the technical role in their name. Never `$spy`, `$mock`,
+ `$stub`, `$fake`, `$dummy`. Use the domain concept the object represents (`$gateway`,
+ `$clock`, `$repository`, `$client`).
+- Class names may carry the technical role as suffix when the class IS a test double
+ (`ClientMock`, `GatewaySpy`, `ClockFake`). The suffix signals that the file is a collaborator
+ built for tests, not a production type.
+
+### Location
+
+- Test doubles live at the root of `tests/Unit/`. When integration tests exist, doubles used
+ there live at the root of `tests/Integration/`.
+- No dedicated `Mocks/` or `Doubles/` subdirectory exists.
+- Domain fixtures that represent real domain concepts live in `tests/Models/`. See
+ `php-library-architecture.md` for the canonical `tests/` folder layout.
+
+## Coverage and mutation discipline
-## Coverage and mutation testing
+- Never use `@codeCoverageIgnore`, attributes, or configuration that exclude code from coverage.
+- Never suppress mutants via `infection.json.dist` or any other mechanism.
+- If a line or mutation cannot be covered or killed, the design is wrong. Refactor the
+ production code to make it testable. Never work around the tool.
-1. Line and branch coverage must be **100%**. No annotations (`@codeCoverageIgnore`), attributes, or configuration
- that exclude code from coverage are allowed.
-2. All mutations reported by Infection must be **killed**. Never ignore or suppress mutants via `infection.json.dist`
- or any other mechanism.
-3. If a line or mutation cannot be covered or killed, it signals a design problem in the production code. Refactor
- the code to make it testable, do not work around the tool.
+Canonical thresholds (MSI 100, covered MSI 100) live in `php-library-tooling.md`. They are
+enforced by `infection.json.dist`. Achieving MSI 100 implies effective full coverage of `src/`
+because every mutation must be killed by an assertion. This file covers only the behavioral
+rules that complement those thresholds.

+Canonical configuration files for a PHP library in the tiny-blocks ecosystem. Each file has a
+fixed shape. Deviations require justification. Folder structure lives in
+`php-library-architecture.md`. Code style lives in `php-library-code-style.md`.
+
+## Pre-output checklist
+
+Verify every item before creating, editing, or relocating any of the files below. If any item
+fails, revise before outputting.
+
+1. The library repository contains all the following files at its root: `composer.json`,
+ `phpcs.xml`, `phpstan.neon.dist`, `phpunit.xml`, `infection.json.dist`, `.editorconfig`,
+ `.gitattributes`, `.gitignore`, `Makefile`.
+2. `composer.json` exposes exactly five scripts: `configure`, `configure-and-update`, `review`,
+ `test-file`, `tests`. No other public scripts are defined.
+3. `composer.json` fixed fields use the canonical values defined in the "composer.json" section
+ (`license`, `type`, `minimum-stability`, `prefer-stable`, `authors`, `config`, `require.php`).
+4. `composer.json` `description` is a single short sentence describing what the library does.
+ Multi-sentence or multi-paragraph descriptions belong in the README Overview, not in Composer
+ metadata.
+5. `composer.json` includes a `keywords` array. The first keyword is always `"tiny-blocks"`.
+ Additional keywords are topic tokens derived from the library's purpose (`psr-7`,
+ `http-client`, `event-sourcing`, etc.).
+6. `phpcs.xml` references only the `PSR12` ruleset. No additional sniffs are added.
+7. `phpunit.xml` sets all five `failOn*` flags to `true`: `failOnDeprecation`, `failOnNotice`,
+ `failOnPhpunitDeprecation`, `failOnRisky`, `failOnWarning`.
+8. `phpunit.xml` sets `executionOrder="random"` and `beStrictAboutOutputDuringTests="true"`.
+9. `infection.json.dist` sets `minMsi: 100` and `minCoveredMsi: 100`. Lowering either value is
+ prohibited.
+10. `.editorconfig` sets `max_line_length = 120`, `indent_size = 4`, `indent_style = space`, and
+ `end_of_line = lf` for PHP files. YAML uses `indent_size = 2`. Makefile uses `indent_style = tab`.
+11. `.gitattributes` sets `* text=auto eol=lf` and lists every dev-only file under `export-ignore`.
+ The Packagist tarball contains only `src/`, `composer.json`, `README.md`, and `LICENSE`.
+ `.claude/` is listed under `export-ignore` (versioned on GitHub for contributor parity,
+ excluded from the published package).
+12. `.gitignore` follows the canonical content in the ".gitignore" section. `.claude/` is **not**
+ listed (it is versioned on GitHub).
+13. `Makefile` wraps every PHP and Composer command in a Docker container using the canonical
+ image `gustavofreze/php:8.5-alpine`. No PHP command runs on the host directly.
+14. All test artifact paths use `reports/` (plural). The directory is consistent across
+ `composer tests`, `infection.json.dist`, `phpunit.xml`, and `Makefile`.
+15. The `reports/` directory is listed under `export-ignore` in `.gitattributes`.
+
+## composer.json
+
+Fixed fields, identical in every library: `license`, `type`, `minimum-stability`, `prefer-stable`,
+`require.php`, `authors`, `config.allow-plugins`, `config.sort-packages`, `scripts`, and the five
+universal dev dependencies (`ergebnis/composer-normalize`, `infection/infection`, `phpstan/phpstan`,
+`phpunit/phpunit`, `squizlabs/php_codesniffer`).
+
+Per-library fields, vary by library: `name`, `description`, `keywords`, `homepage`, `support`,
+`autoload`, `autoload-dev`. The `require-dev` section may add libraries needed by tests (for
+example, HTTP client implementations in a PSR-7 library) on top of the five universal tools.

+ }
+}
+```
+
+Script usage:
+
+- `composer configure` runs `composer install --optimize-autoloader` followed by `composer normalize`.
+ Use this after cloning the repository or pulling new changes.
+- `composer configure-and-update` runs `composer update --optimize-autoloader` followed by
+ `composer normalize`. Use this when intentionally updating dependencies.
+- `composer review` runs `phpcs` and `phpstan` in sequence. Used by CI and local validation.
+- `composer tests` runs `phpunit` followed by `infection`. Used by CI.
+- `composer test-file ` runs a filtered subset of tests without coverage. Local
+ development only.
+
+## phpcs.xml
+
+References only the `PSR12` ruleset. Additional formatting rules (vertical alignment, trailing
+comma, etc.) live in `php-library-code-style.md` under "Formatting overrides".
+
+```xml
+
+
+ Code style for the tiny-blocks library.
+
+ src
+ tests
+
+```
+
+## phpstan.neon.dist
+
+Static analysis configuration. Runs at the highest level on both `src/` and `tests/`. Invoked
+by the `review` Composer script.
+
+```neon
+parameters:
+ level: max
+ paths:
+ - src
+ - tests
+ reportUnmatchedIgnoredErrors: true
+```
+
+`ignoreErrors` is permitted to suppress legitimate false positives produced by `level: max`
+(third-party type signatures with `mixed`, PHP-FIG interfaces returning untyped arrays, trait
+unused-method warnings on shared behavior, etc.). Each entry follows these rules:
+
+- A short comment above the entry justifies its existence.
+- Prefer scoping via `identifier:` plus `path:` over raw `#...#` message patterns.
+- `reportUnmatchedIgnoredErrors: true` is mandatory. Obsolete entries fail the build, forcing
+ cleanup.
+
+Example with `ignoreErrors`:
+
+```neon
+parameters:
+ level: max
+ paths:
+ - src
+ - tests
+ ignoreErrors:
+ # Trait method intentionally unused by the consuming aggregate; reflection wires it.
+ - identifier: trait.unused
+ path: src/Internal/EventualAggregateRootBehavior.php
+
+ # json_encode signature carries `mixed` for backward compatibility at level max.
+ - identifier: argument.type
+ path: src/Internal/Serialization/JsonEncoder.php
+ reportUnmatchedIgnoredErrors: true
+```
+
+## phpunit.xml
+
+Strict configuration. All `failOn*` flags are `true`. `executionOrder="random"` forces tests to be
+independent of one another. Coverage and JUnit reports go under `reports/`.
+
+```xml
+
+
+
+
+
+ src
+
+
+
+
+
+ tests
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+```
+
+Root attributes are sorted alphabetically.
+
+## infection.json.dist
+
+Mutation testing configuration. `minMsi` and `minCoveredMsi` are both `100`. Mutants that escape
+make the build fail.
+
+```json
+{
+ "logs": {
+ "text": "reports/infection/logs/infection-text.log",
+ "summary": "reports/infection/logs/infection-summary.log"
+ },
+ "tmpDir": "reports/infection/",
+ "minMsi": 100,
+ "timeout": 30,
+ "source": {
+ "directories": [
+ "src"
+ ]
+ },
+ "phpUnit": {
+ "configDir": "",
+ "customPath": "./vendor/bin/phpunit"
+ },
+ "mutators": {
+ "@default": true
+ },
+ "minCoveredMsi": 100,
+ "testFramework": "phpunit"
+}
+```
+
+## .editorconfig
+
+Whitespace and line ending rules applied by editor integrations.
+
+```ini
+root = true
+
+[*]
+charset = utf-8
+end_of_line = lf
+indent_size = 4
+indent_style = space
+max_line_length = 120
+insert_final_newline = true
+trim_trailing_whitespace = true
+
+[*.{yml,yaml}]
+indent_size = 2
+
+[Makefile]
+indent_style = tab
+
+[*.md]
+trim_trailing_whitespace = false
+```
+
+## .gitattributes
+
+Normalizes line endings to LF and excludes every dev-only file from the Packagist tarball. The
+published package contains only `src/`, `composer.json`, `README.md`, and `LICENSE`.
+
+```
+* text=auto eol=lf
+
+*.php text diff=php

+```
+
+## .gitignore
+
+Keeps the repository working tree clean of artifacts that should never be committed. Entries
+are grouped from most fundamental (PHP dependencies) to least critical (OS files). The
+`.claude/` directory is **not** listed here. It is versioned on GitHub so other contributors
+share the same rules, and it is excluded from the published Packagist tarball through
+`export-ignore` in `.gitattributes` (see above).

## Context
-PHP library (tiny-blocks). Immutable domain models, zero infrastructure dependencies in core.
+PHP library in the tiny-blocks ecosystem.
## Mandatory pre-task step
-Before starting any task, read and strictly follow all instruction files located in `.claude/CLAUDE.md` and
-`.claude/rules/`. These files are the absolute source of truth for code generation. Apply every rule strictly. Do not
-deviate from the patterns, folder structure, or naming conventions defined in them.

+### 07. How are outbox records ordered?
-The `sequence` column (`BIGINT AUTO_INCREMENT`) is the authoritative global ordering. The database fills it at commit
