-# Bruno API Collection
-
-A [Bruno](https://www.usebruno.com/) collection lives in `.bruno/` and mirrors every Gotenberg route. When adding or updating a route, update the collection to match.

-## `.bru` File Format
-
-```bru
-meta {
-  name: <Human-readable name>
-  type: http
-  seq: <order within folder>
-}
-
-post {
-  url: {{baseUrl}}/forms/<path>
-  body: multipartForm
-  auth: none
-}
-
-body:multipart-form {
-  files: @file(../../test/integration/testdata/<file>)
-  <mandatoryField>: <value>
-  ~<optionalField>: <value>
-}
-
-headers {
-  ~Gotenberg-Output-Filename: <name>
-  ~Gotenberg-Webhook-Url: http://localhost:8080/webhook
-  ~Gotenberg-Webhook-Error-Url: http://localhost:8080/webhook/error
-  ~Gotenberg-Webhook-Method: POST
-  ~Gotenberg-Webhook-Error-Method: POST
-  ~Gotenberg-Webhook-Extra-Http-Headers: {"X-Custom":"value"}
-}
-```
-
-## Conventions
-
-- **Mandatory fields** are listed without prefix; **optional fields** are prefixed with `~` (disabled by default in Bruno).
-- **File references** use relative paths to `test/integration/testdata/`.
-- **Webhook and output filename headers** are included on every POST route as optional (`~`).
-- **One `.bru` file per request**. For routes with read/write variants (e.g., bookmarks, metadata), create separate files in the same folder.
-
-## Checklist When Adding/Updating a Route
-
-1. Create or update the `.bru` file in the matching folder under `.bruno/`.
-2. Include all form fields from the route handler — check `FormData*` calls in the route function.
-3. For file upload fields (`files`, `watermark`, `stamp`, `embeds`), use `@file(...)` with a suitable test file.
-4. Verify the URL path matches the route's `Path` field exactly.
-5. If you add a new module folder, keep the naming consistent (e.g., `PDF Engines/Rotate/`).

-# Operational Guidelines for Gotenberg
-
-You are working on **Gotenberg**, a Docker-based API for converting documents to PDF. It is a widely used production dependency. Stability and backward compatibility are paramount. When in doubt about whether a change is breaking, flag it rather than assuming it's safe.
-
-## Mandatory Workflow
-
-Every task MUST follow these five steps in order. Do not skip any step.
-
-### Step 1 — Plan
-
-Before writing any code, produce a plan that covers:
-
-- **Problem statement**: What needs to change and why.
-- **Proposed solution**: The recommended approach with enough detail to implement (files to modify, interface changes, pipeline positioning, form fields, etc.).
-- **Alternatives considered**: At least one alternative approach when pertinent, with a brief explanation of why the proposed solution is preferred.
-- **Scope**: List every file that will be created or modified.
-- **Testing strategy**: Which integration test tags will be affected, what new scenarios are needed, and whether unit tests are required.
-
-Present the plan to the user and wait for approval before proceeding to Step 2. If the user provides a plan, validate it against the codebase and flag any issues before implementing.
-
-### Step 2 — Implement
-
-Implement the approved plan following the coding standards and patterns described in this document. After implementation, verify the build compiles (`go build ./...`).
-
-### Step 3 — Test
-
-Write or update tests based on the plan's testing strategy:
-
-- **Integration tests** (primary): Gherkin scenarios in `test/integration/features/`. See [`test/integration/AGENTS.md`](test/integration/AGENTS.md) for the full reference.
-- **Unit tests** (when applicable): Table-driven tests in `*_test.go` files using mocks from `pkg/gotenberg/mocks.go`.
-
-### Step 4 — Review
-
-Self-review the implementation against the [Review Checklist](#review-checklist). Fix any issues found before presenting the result to the user.
-
-### Step 5 — Commit
-
-Present the review to the user and **wait for explicit approval**. Do NOT commit until the user confirms. Once approved, create a commit following the [Conventional Commits](https://www.conventionalcommits.org/) specification:
-
-```
-<type>(<scope>): <description>
-```
-
-Common types: `feat`, `fix`, `refactor`, `test`, `docs`, `chore`, `ci`, `build`. The scope should match the module or area of the change (e.g., `chromium`, `pdfengines`, `api`).
-
-Stage only the files related to the change. Do not use `git add -A` or `git add .`.
-
----
-
-## Core Principles
-
-- **Backward compatibility is law.** Never modify existing CLI flags, environment variables, or API form fields unless explicitly instructed to perform a breaking change. Flag any breaking change immediately.
-- **Defensive programming.** Assume input is malformed. Handle errors explicitly. Never panic.
-- **Atomic commits.** One feature or fix per PR. Isolate refactoring from feature work.
-- **Idiomatic Go.** Follow "Effective Go" principles. All exported symbols must have GoDoc comments starting with their name.
-
-## Project Layout
-
-```
-cmd/gotenberg/       → Entry point only (wiring/startup). No business logic.
-pkg/gotenberg/       → Core module system, interfaces, utilities, mocks.
-pkg/modules/         → Feature modules (api, chromium, libreoffice, pdfengines, etc.).
-pkg/standard/        → Wires all standard modules together via imports.
-test/integration/    → Gherkin feature files + Go test infrastructure.
-build/               → Dockerfile, fonts, Chromium config.
-.bruno/              → Bruno API collection (mirrors every route).
-```
-
-Key interfaces live in `pkg/gotenberg/` — `Module`, `Provisioner`, `Validator`, `Debuggable`. Every module implements `Descriptor()` and self-registers. When adding features, determine if they belong in an existing module or require a new one.
-
-## Codebase Navigation
-
-- Start with `pkg/gotenberg/` for core interfaces and `pkg/modules/` for feature implementations.
-- The integration test infrastructure in `test/integration/scenario/` is well-structured — read `scenario.go` and `containers.go` to understand the Gherkin step definitions before writing new tests.
-- Mocks for all major interfaces are in `pkg/gotenberg/mocks.go` — use them for unit tests rather than creating new ones.
-- Import ordering is enforced: standard library, third-party, then `github.com/gotenberg/gotenberg/v8` — separated by blank lines.
-- When making changes, run only the relevant integration test tag rather than the full suite (40min timeout).
-- Telemetry infrastructure lives in `pkg/gotenberg/telemetry.go` (global Logger, Tracer, Meter) and `pkg/gotenberg/internal/` (log handlers, OTEL SDK init). HTTP semantic conventions are in `pkg/gotenberg/semconv/`.

-## Makefile — the Only Build Interface
-
-All build and verification tasks go through the Makefile. Do not run `go` commands directly unless debugging a specific package.

-## Module System
-
-Gotenberg uses a self-registering module architecture inspired by CaddyServer. Each module:
-
-- Lives in `pkg/modules/<name>/`
-- Implements the `gotenberg.Module` interface (at minimum `Descriptor()`)
-- May also implement `gotenberg.Provisioner`, `gotenberg.Validator`, or `gotenberg.Debuggable`
-- Self-registers via `init()` and is wired through `pkg/standard/`
-
-When adding a feature, first determine if it belongs in an existing module. Only create a new module if the feature represents a genuinely separate concern.
-
-## Coding Patterns
-
-- **Error handling:** Always wrap errors with context using `fmt.Errorf("description: %w", err)`. Never swallow errors silently.
-- **Import ordering:** Enforced by `gci` — standard library, then third-party, then `github.com/gotenberg/gotenberg/v8`. Three groups separated by blank lines.
-- **Mocks:** Comprehensive mock implementations for all major interfaces live in `pkg/gotenberg/mocks.go`. Use these for unit tests.
-- **Logging:** Use `gotenberg.Logger(mod)` to get the module's slog logger during `Provision()`. All log calls must be context-aware: `logger.DebugContext(ctx, msg)`, `logger.InfoContext(ctx, msg)`, `logger.ErrorContext(ctx, msg)`. This propagates trace/span IDs into structured logs when OpenTelemetry is active.
-- **Telemetry:** External tool calls (Chromium, LibreOffice, PDF engines, webhooks, downloads) must create OTEL spans with `trace.SpanKindClient` and `semconv.ServerAddress("toolname")`. Use `gotenberg.Tracer()` and `gotenberg.Meter()` for traces and metrics respectively.
-- **No business logic in `cmd/`:** The `cmd/gotenberg/` package is strictly for wiring and startup.
-

-
-## Review Checklist
-
-### Backward Compatibility
-
-- [ ] No existing CLI flags renamed or removed
-- [ ] No existing environment variables renamed or removed
-- [ ] No existing API form fields renamed or removed
-- [ ] No existing HTTP endpoints changed or removed
-- [ ] No changes to default values that alter existing behavior
-- [ ] Deprecated flags have both old and new names registered, with `fs.MarkDeprecated()`
-
-If any of these are violated, the change **must** be flagged as a breaking change.
-
-### Linting Standards
-
-The `.golangci.yml` enforces strict rules including: `gosec`, `govet`, `errcheck`, `staticcheck`, `dupl`, `bodyclose`, `exhaustive`, `errname`, `sloglint`, `gocritic`, and more. Zero linting errors are permitted.
-
-Formatters enforce `gci`, `gofmt`, `gofumpt`, `goimports` with import ordering:
-
-1. Standard library
-2. Third-party packages
-3. `github.com/gotenberg/gotenberg/v8`
-
-Three groups separated by blank lines.
-
-### Code Quality
-
-- Errors are wrapped with context: `fmt.Errorf("description: %w", err)`. No swallowed errors.
-- No business logic in `cmd/`.
-- No panics in production code paths.
-- Input is validated defensively.
-- New features belong in the correct module (or justify a new one).
-
-### Documentation
-
-- Every exported function, type, constant, and variable has a GoDoc comment starting with its name.
-- New packages include a `doc.go` file.
-- `README.md` is not modified unless explicitly requested.
-
-### Definition of Done
-
-A change is ready to merge only when:
-
-1. Code compiles: `go build ./...`
-2. Code is formatted: `make fmt`
-3. All linters pass: `make lint` and `make lint-prettier`
-4. Integration tests pass: `make test-integration` (at minimum, the relevant `TAGS`)
-5. Unit tests pass: `make test-unit`
-6. All exported symbols and new packages have compliant GoDoc
-7. Bruno collection is updated (if routes were added or modified)
-

-## Scoped Guidelines
-
-Detailed guidelines for specific areas of the codebase live in their own `AGENTS.md` files:
-
-- [`test/integration/AGENTS.md`](test/integration/AGENTS.md) — Integration test framework, Gherkin step reference, available tags, and how to write new tests.
-- [`.bruno/AGENTS.md`](.bruno/AGENTS.md) — Bruno API collection structure, `.bru` file format, conventions, and route update checklist.

 # Contributing to Gotenberg
 
-Thank you for your interest in contributing to Gotenberg! This guide will help you get started.
+Gotenberg is a Docker-based API for converting documents to PDF. Two rules override everything else: **backward compatibility** (never rename or remove CLI flags, environment variables, API form fields, or HTTP endpoints without discussion) and **defensive programming** (assume input is malformed, handle errors explicitly, never panic).

+Use `gotenberg.Logger(mod)` to get the module's slog logger during `Provision()`. All log calls must be context-aware: `logger.DebugContext(ctx, msg)`, `logger.InfoContext(ctx, msg)`, `logger.ErrorContext(ctx, msg)`. This propagates trace/span IDs into structured logs when OpenTelemetry is active.
+
+### Telemetry
+
+External tool calls (Chromium, LibreOffice, PDF engines, webhooks, downloads) must create OTEL spans with `trace.SpanKindClient` and `semconv.ServerAddress("toolname")`. Use `gotenberg.Tracer()` and `gotenberg.Meter()` for traces and metrics.
+
+### No business logic in `cmd/`
+
+The `cmd/gotenberg/` package is strictly for wiring and startup.
+
+### Mocks
+
+Comprehensive mock implementations for all major interfaces live in `pkg/gotenberg/mocks.go`. Use these for unit tests rather than creating new ones.
+
+## Documentation rules
+
+### Tone
+
+- Short, declarative sentences. Say what it does, then stop.
+- Lead with the action. "Validates font embedding", not "This function validates font embedding".
+- Active voice. "Gotenberg checks the profile", not "The profile is checked by Gotenberg".
+- No em dashes. Use a period, colon, or comma.
+- No "we" hedging. "Don't...", not "We do not recommend...".
+
+### Godoc
+
+Every exported type and function has a Godoc comment starting with its identifier name:
+
+```go
+// Violation records a single rule violation with context.
+type Violation struct { ... }
+
+// ValidatePDFA audits the document against a PDF/A profile.
+func ValidatePDFA(ctx context.Context, ...) ([]error, error)
+```
+
+Each package should have a `doc.go` with a `// Package foo ...` comment.
+
+Reference identifiers with `[Name]` brackets for pkg.go.dev linking:
+
+```go
+// ValidatePDFA returns violations as []error where each element
+// is a [Violation] value. See [Rule] for the structured fields.
+```
+
+### Code comments
+
+- Explain _why_, not _what_.
+- No numbered step comments (`// 1. Do X`, `// 2. Do Y`).
+- No section dividers with numbers (`// --- 8. Foo ---`). Plain dividers are fine for major boundaries.
+- No noise comments that restate the code (`// Check if err is nil`, `// Return results`).
+- Reference spec clauses where relevant (`// Per ISO 32000-2, Table 116...`).
+- Mark debt with `// TODO: [context]`.
+
+### Formatting non-Go files
+
+Run `make prettify && make lint-prettier` for YAML, Markdown, and JSON.
+
+## Testing
+
+Integration tests use Gherkin (BDD) via Godog with `testcontainers-go` for Docker orchestration. Feature files live in `test/integration/features/`. Step definitions live in `test/integration/scenario/`. Read `scenario.go` and `containers.go` to understand step definitions before writing new tests.
+
+Unit tests: table-driven tests in `*_test.go` files using mocks from `pkg/gotenberg/mocks.go`.
+
+Run only the relevant integration test tag rather than the full suite (40min timeout).
+
+See:
+
+- [`test/integration/README.md`](test/integration/README.md): Gherkin step reference, available tags, writing new tests.
+- [`.bruno/README.md`](.bruno/README.md): `.bru` file format, conventions, route update checklist.
+- [`pkg/modules/pdfengines/README.md`](pkg/modules/pdfengines/README.md): adding new engine features (Makefile variable and flag).
+
+## Pull requests
+
+Plan non-trivial changes before coding. Open an issue or draft PR describing what needs to change, the proposed solution (files to modify, interface changes, form fields), and which integration test tags are affected.
 
 ### Guidelines
 
-- **Conventional Commits.** Commit messages must follow the [Conventional Commits](https://www.conventionalcommits.org/) specification (e.g., `feat(chromium): add screenshot endpoint`, `fix(api): handle empty body`).
-- **One thing per PR.** Keep features, bug fixes, and refactoring in separate PRs.
-- **Backward compatibility matters.** Do not rename or remove existing CLI flags, environment variables, or API form fields without discussion.
-- **Integration tests first.** When adding a feature or route, start by writing the Gherkin scenario in `test/integration/features/`.
-- **Logging uses `gotenberg.Logger(mod)`** with context-aware calls (`*Context` variants).
-- **External operations have OTEL traces** with appropriate SpanKind and semconv attributes.
-- **No business logic in `cmd/`.** All logic belongs in `pkg/`.
+- One thing per PR. Keep features, bug fixes, and refactoring separate.
+- Backward compatibility matters. Do not rename or remove existing CLI flags, environment variables, or API form fields without discussion.
+- Integration tests first. When adding a feature or route, start by writing the Gherkin scenario.
+- Bruno collection must be updated if routes were added or modified.
 
-## Detailed Guidelines
+### Checklist
 
-The [`AGENTS.md`](AGENTS.md) files contain comprehensive guidelines used by both human contributors and AI-assisted tools:
+- [ ] No existing CLI flags renamed or removed
+- [ ] No existing environment variables renamed or removed
+- [ ] No existing API form fields renamed or removed
+- [ ] No existing HTTP endpoints changed or removed
+- [ ] No changes to default values that alter existing behavior
+- [ ] Deprecated flags have both old and new names registered, with `fs.MarkDeprecated()`
+- [ ] Errors wrapped with context: `fmt.Errorf("description: %w", err)`
+- [ ] No business logic in `cmd/`
+- [ ] No panics in production code paths
+- [ ] New features belong in the correct module (or justify a new one)
+- [ ] Linting: `make fmt && make lint && make prettify && make lint-prettier` passes with zero warnings
+- [ ] Every exported function, type, constant, and variable has a Godoc comment starting with its name
+- [ ] New packages include a `doc.go` file
+- [ ] Integration tests pass: `make test-integration` (at minimum, the relevant tags)
+- [ ] Unit tests pass: `make test-unit`
+- [ ] Bruno collection updated (if routes were added or modified)

+
+### Commits
+
+[Conventional Commits](https://www.conventionalcommits.org/): `<type>(<scope>): <description>`.
+
+Common types: `feat`, `fix`, `refactor`, `test`, `docs`, `chore`, `ci`, `build`. The scope should match the module or area of the change (e.g., `chromium`, `pdfengines`, `api`).
+
+Stage specific files. Never `git add -A` or `git add .`.

-When adding a new PDF engine capability (e.g., bookmarks, watermark, stamp, embed), you must update the Makefile to include the corresponding engine list variable and flag.

-
-1. **Add a variable** in the Makefile's variable block (around line 60-70):
-   ```makefile

-2. **Add the flag** in the Makefile's command args block (around line 140-155):

+# Adding PDF Engine Features
+
+Each new PDF engine capability (bookmarks, watermark, stamp, embed, etc.) requires a matching Makefile entry. The Makefile variables control which engines are passed to Gotenberg at `make run` and `make test-integration` time via `compose.yaml`. Skip this step and `make run` falls back to the default defined in `pdfengines.go`, which may not include the new engine.
+
+Every `--pdfengines-*-engines` flag registered in `pdfengines.go` needs two additions:
+
+1. A variable in the Makefile's variable block (around line 60-70):
+
+   ```makefile
+   PDFENGINES_<FEATURE>_ENGINES=<default engines>
+   ```
+
+2. A flag in `compose.yaml`'s command args:
+
+   ```yaml
+   - "--pdfengines-<feature>-engines=${PDFENGINES_<FEATURE>_ENGINES}"
+   ```
+
+The default value must match the `fs.StringSlice(...)` call for that flag in `pdfengines.go`.
+
+## Example: Rotate
+
+Rotate was added with two engines (`pdfcpu` and `pdftk`):
+
+**Makefile** (variable block):
+
+```makefile
+PDFENGINES_ROTATE_ENGINES=pdfcpu,pdftk
+```
+
+**compose.yaml** (command args):
+

+- "--pdfengines-rotate-engines=${PDFENGINES_ROTATE_ENGINES}"

-# Integration Tests
-
-- **Framework:** Gherkin (BDD) via [Godog](https://github.com/cucumber/godog), with `testcontainers-go` for Docker orchestration.
-- **Feature files:** `test/integration/features/*.feature` — one file per endpoint or capability.
-- **Test infrastructure:** `test/integration/scenario/` — Go step definitions, container management, HTTP helpers, PDF validation.
-- **Entry point:** `test/integration/main_test.go` (build tag: `integration`).
-- **Test data:** `test/integration/testdata/`
-
-## How It Works
-
-Each scenario spins up a fresh Gotenberg Docker container via testcontainers. The step definitions in `scenario/scenario.go` map Gherkin steps to Go functions. An additional `gotenberg/integration-tools` container provides PDF validation tools (`verapdf`, `pdfinfo`, `pdftotext`).
-
-**Important:** Integration tests require a Docker image. Run `make build` before `make test-integration`.
-
-## Selective Test Runs
-
-Use the `TAGS` variable to run only relevant scenarios:
-
-```bash
-make test-integration TAGS=health
-make test-integration TAGS=chromium-convert-html
-make test-integration TAGS="merge,split"
-```
-
-Available tags: `chromium`, `chromium-concurrent`, `chromium-convert-html`, `chromium-convert-markdown`, `chromium-convert-url`, `chromium-screenshot-html`, `chromium-screenshot-markdown`, `chromium-screenshot-url`, `debug`, `health`, `libreoffice`, `libreoffice-convert`, `output-filename`, `pdfengines`, `pdfengines-convert`, `pdfengines-embed`, `embed`, `pdfengines-encrypt`, `encrypt`, `pdfengines-flatten`, `flatten`, `pdfengines-merge`, `merge`, `pdfengines-metadata`, `metadata`, `pdfengines-split`, `split`, `pdfengines-watermark`, `watermark`, `pdfengines-stamp`, `stamp`, `pdfengines-bookmarks`, `bookmarks`, `pdfengines-rotate`, `rotate`, `prometheus-metrics`, `root`, `version`, `webhook`, `download-from`.
-
-Other useful flags:
-
-```bash
-make test-integration NO_CONCURRENCY=true  # Disable parallel scenarios
-make test-integration PLATFORM=linux/arm64 # Force a specific platform
-```
-
-## Writing a New Integration Test
-
-1. Create or update a `.feature` file in `test/integration/features/`.
-2. Tag it appropriately (e.g., `@chromium @chromium-convert-html`).
-3. If the feature requires new tag(s), add them to both the `TAGS` comment block in the `Makefile` and the "Available tags" list above.
-4. If you create a new step definition, add it to `scenario/scenario.go`, register it in `InitializeScenario`, and update the "Available Gherkin Steps" list below.
-5. Test data goes in `test/integration/testdata/`.
-
-## Available Gherkin Steps
-
-**Given (setup):**
-
-- `I have a default Gotenberg container`
-- `I have a Gotenberg container with the following environment variable(s):` (table: key | value)
-- `I have a (webhook|static) server`
-
-**When (action):**
-
-- `I make a "(GET|HEAD)" request to Gotenberg at the "<endpoint>" endpoint`
-- `I make a "(GET|HEAD)" request to Gotenberg at the "<endpoint>" endpoint with the following header(s):` (table: name | value)
-- `I make a "(POST)" request to Gotenberg at the "<endpoint>" endpoint with the following form data and header(s):` (table: name | value | kind — where kind is `file`, `field`, or `header`)
-- `I make <N> concurrent "(POST)" requests to Gotenberg at the "<endpoint>" endpoint with the following form data and header(s):` (same table format)
-- `I wait for the asynchronous request to the webhook`
-
-**Then (assertions):**
-
-- `the response status code should be <code>`
-- `the (response|webhook request) header "<name>" should be "<value>"`
-- `the (response|webhook request) cookie "<name>" should be "<value>"`
-- `the (response|webhook request) body should match string:` (docstring)
-- `the (response|webhook request) body should contain string:` (docstring)
-- `the (response|webhook request) body should match JSON:` (docstring — use `"ignore"` for dynamic values like timestamps)
-- `the webhook event should match JSON:` (docstring — use `"ignore"` for dynamic values; polls for up to 5s)
-- `there should be <N> PDF(s) in the (response|webhook request)`
-- `there should be the following file(s) in the (response|webhook request):` (table of filenames)
-- `the "<name>" PDF should have <N> page(s)`
-- `the "<name>" PDF (should|should NOT) be set to landscape orientation`
-- `the "<name>" PDF (should|should NOT) have the following content at page <N>:` (docstring)
-- `the (response|webhook request) PDF(s) should be valid "<standard>" with a tolerance of <N> failed rule(s)` (standards: `PDF/A-1b`, `PDF/A-2b`, `PDF/A-3b`, `PDF/UA-1`, `PDF/UA-2`)
-- `the (response|webhook request) PDF(s) (should|should NOT) be flatten`
-- `the (response|webhook request) PDF(s) (should|should NOT) be encrypted`
-- `the (response|webhook request) PDF(s) (should|should NOT) have the "<filename>" file embedded`
-- `the Gotenberg container (should|should NOT) log the following entries:` (table of log substrings)
-- `all concurrent response status codes should be <code>`
-- `all concurrent responses should have <N> PDF(s)`
