+
+# CI E2E Debug Skill
+
+Download test log artifacts from a GitHub Actions CI run and inspect them for errors.
+
+## Steps
+
+1. **Find the artifact**: Use `gh api` to list artifacts for the given CI run:
+   ```bash
+   gh api repos/apache/skywalking/actions/runs/<RUN_ID>/artifacts --jq '.artifacts[] | {id: .id, name: .name}'
+   ```
+
+2. **Download and extract**: Download the artifact zip and extract it:
+   ```bash
+   cd /tmp && rm -rf e2e-debug-logs && mkdir e2e-debug-logs && cd e2e-debug-logs
+   gh api repos/apache/skywalking/actions/artifacts/<ARTIFACT_ID>/zip > artifact.zip
+   unzip -o artifact.zip
+   ```
+
+3. **Inspect OAP logs**: Look for errors in the OAP server logs:
+   ```bash
+   # Find OAP log files
+   find /tmp/e2e-debug-logs -name "skywalking-oap-*.log" -o -name "oap.log"
+   # Check for errors
+   grep -E "ERROR|Exception|FATAL|CannotCompileException" <log_file> | head -30
+   ```
+
+4. **Inspect other component logs**: Check BanyanDB, UI, and other pod logs as needed.
+
+5. **Report findings**: Summarize the root cause error from the logs.
+
+## Notes
+- CI artifacts are automatically uploaded by the e2e test framework to `$SW_INFRA_E2E_LOG_DIR`
+- Log files are organized by namespace/pod name
+- OAP init pods may have different errors than the main OAP pod — check all of them
+- Common errors: MAL/LAL/OAL compilation failures, storage connection issues, module initialization errors

+description: Build SkyWalking OAP server, run javadoc checks, and verify checkstyle. Use to validate changes before submitting a PR.
+argument-hint: "[all|backend|javadoc|checkstyle|module-name]"
+---
+
+# Compile & Verify
+
+Build the project and run static checks matching CI.
+
+## Prerequisites
+
+- JDK 11, 17, or 21 (LTS versions)
+- Maven 3.6+ (use `./mvnw` wrapper)
+
+## Maven profiles
+
+- `backend` (default): Builds OAP server modules
+- `ui` (default): Builds web application
+- `dist` (default): Creates distribution packages
+- `all`: Builds everything including submodule initialization
+
+## Commands by argument
+
+### `all` or no argument — full CI build
+
+```bash
+./mvnw clean flatten:flatten install javadoc:javadoc -B -q -Pall \
+  -Dmaven.test.skip \
+  -Dcheckstyle.skip \
+  -Dgpg.skip
+```
+
+### `backend` — backend only (faster)
+
+```bash
+./mvnw clean flatten:flatten package -Pbackend,dist -Dmaven.test.skip
+```
+
+### `javadoc` — javadoc check only
+
+Javadoc requires delombok output, so `install` must run first:
+
+```bash
+./mvnw clean flatten:flatten install javadoc:javadoc -B -q -Pall \
+  -Dmaven.test.skip \
+  -Dcheckstyle.skip \
+  -Dgpg.skip
+```
+
+Running `javadoc:javadoc` alone without `install` will miss errors because `${delombok.output.dir}` won't be populated.
+
+### `checkstyle` — checkstyle only
+
+```bash
+./mvnw -B -q clean flatten:flatten checkstyle:check
+```
+
+### Module name — single module build
+
+```bash
+./mvnw clean flatten:flatten package -pl oap-server/analyzer/<module-name> -Dmaven.test.skip
+```
+
+## Reading javadoc output
+
+Maven prefixes all javadoc output with `[ERROR]`, but the actual severity is in the message after the line number. Only lines containing `error:` fail the build; lines with `warning:` do not.
+
+```
+[ERROR] Foo.java:42: error: bad use of '>'        ← ACTUAL ERROR (must fix)
+[ERROR] Foo.java:50: warning: no @param for <T>   ← WARNING (does not fail build)
+```
+
+### Common javadoc errors
+
+| Error | Cause | Fix |
+|-------|-------|-----|
+| `bad use of '>'` | Bare `>` in javadoc HTML (e.g., `->` in `<pre>` blocks) | Use `{@code ->}` or `-&gt;` |
+| heading out of sequence | Heading level skips the expected hierarchy | See heading rules below |
+| reference not found | `{@link Foo#bar()}` with wrong signature | Match exact parameter types: `{@link Foo#bar(ArgType)}` |
+
+### Javadoc heading rules (JDK 13+)
+
+Strict heading validation was introduced in JDK 13. JDK 11 does **not** enforce it, but JDK 17/21/25 do. Write headings correctly for forward compatibility:
+
+| Javadoc location | Start heading at |
+|---|---|
+| Class, interface, enum, package, module | `<h2>` |
+| Constructor, method, field | `<h4>` |
+| Standalone HTML files (`doc-files/`) | `<h1>` |
+
+The generated javadoc page uses `<h1>` for the class name and `<h3>` for member sections (Methods, Fields, etc.), so class-level subsections must use `<h2>` and method-level subsections must use `<h4>` to maintain proper nesting.
+
+## CI reference
+
+CI uses JDK 11 on Linux. The `dist-tar` job runs:
+
+```bash
+./mvnw clean flatten:flatten install javadoc:javadoc -B -q -Pall \
+  -Dmaven.test.skip \
+  -Dcheckstyle.skip \
+  -Dgpg.skip
+```
+
+The `code-style` job runs:
+
+```bash
+./mvnw -B -q clean flatten:flatten checkstyle:check
+```

+# PR Branch Workflow
+
+Run pre-flight checks, commit, push, and optionally create a PR.
+
+## Pre-flight checks
+
+Run these checks before every commit+push and fix any failures:
+
+### 1. Compile and checkstyle
+
+```bash
+# Checkstyle
+./mvnw -B -q clean checkstyle:check

+### 2. License header check
+
+```bash
+license-eye header check
+```
+
+If invalid files are found, fix with `license-eye header fix` and re-check.
+
+## Commit and push
+
+After checks pass, commit and push:
+
+```bash
+git add <files>
+git commit -m "<message>"
+git push -u origin <branch-name>
+```
+
+### Branch strategy
+- **Never work directly on master branch**
+- If on master, create a new branch first: `git checkout -b feature/<name>` or `git checkout -b fix/<name>`
+
+## Create PR (if not yet created)
+
+Check whether a PR already exists for the current branch:
+
+```bash
+gh pr view --json number 2>/dev/null
+```
+
+If no PR exists, create one:
+
+### PR title
+Summarize the changes concisely. Examples:
+- `Fix BanyanDB query timeout issue`
+- `Add support for OpenTelemetry metrics`
+
+### PR description
+
+Read `.github/PULL_REQUEST_TEMPLATE` and use its **exact format with checkboxes**. Do NOT use a custom summary format.
+
+Key template sections — uncomment the relevant one:
+
+**For Bug Fixes:**
+```
+### Fix <bug description or issue link>
+- [ ] Add a unit test to verify that the fix works.
+- [ ] Explain briefly why the bug exists and how to fix it.
+```
+
+**For New Features:**
+```
+### <Feature description>
+- [ ] If this is non-trivial feature, paste the links/URLs to the design doc.
+- [ ] Update the documentation to include this new feature.
+- [ ] Tests(including UT, IT, E2E) are added to verify the new feature.
+- [ ] If it's UI related, attach the screenshots below.
+```
+
+**For Performance Improvements:**
+```
+### Improve the performance of <class or module or ...>
+- [ ] Add a benchmark for the improvement.
+- [ ] The benchmark result.
+- [ ] Links/URLs to the theory proof or discussion articles/blogs.
+```
+
+**Always include:**
+```
+- [ ] If this pull request closes/resolves/fixes an existing issue, replace the issue number. Closes #<issue number>.
+- [ ] Update the [`CHANGES` log](https://github.com/apache/skywalking/blob/master/docs/en/changes/changes.md).
+```
+
+### Create command
+
+```bash
+gh pr create --title "<title>" --body "$(cat <<'EOF'
+<PR body from template>
+EOF
+)"
+```
+
+### Post-creation
+- Add `copilot` as a reviewer: `gh pr edit <number> --add-reviewer copilot`
+- Do NOT add AI assistant as co-author. Code responsibility is on the committer's hands.
+- Return the PR URL when done.

+description: Check and fix Apache 2.0 license headers and dependency licenses using skywalking-eyes. Use before submitting a PR.

+---
+
+# License Checks
+
+Check and fix license compliance using [skywalking-eyes](https://github.com/apache/skywalking-eyes). Two CI jobs use this tool:
+
+1. **license-header** — verifies all source files have Apache 2.0 headers
+2. **dependency-license** — verifies the LICENSE file matches current dependencies
+
+## Steps
+
+### Header check (default, or `check` argument)
+
+```bash
+license-eye header check
+```
+
+- **All valid**: Output shows `valid: N, invalid: 0` — nothing to do.
+- **Invalid files found**: Fix with `license-eye header fix`, then re-check.
+
+### Header fix (`fix` argument)
+
+```bash
+license-eye header fix
+license-eye header check
+```
+
+### Dependency license check (`deps` argument)
+
+This regenerates the LICENSE file from dependency metadata and checks for drift:
+
+```bash
+license-eye dependency resolve --summary ./dist-material/release-docs/LICENSE.tpl || exit 1
+if [ ! -z "$(git diff -U0 ./dist-material/release-docs/LICENSE)" ]; then
+  echo "LICENSE file is not updated correctly"
+  git diff -U0 ./dist-material/release-docs/LICENSE
+fi
+```
+
+If the LICENSE file changed, review the diff and commit it. **Important**: CI runs on Linux — some dependencies have platform-specific variants. If you're on macOS/Windows, the LICENSE diff may be a platform artifact. Verify before committing.
+
+## Rules
+
+Configuration is in `.licenserc.yaml`:
+- Java, XML, YAML/YML files require Apache 2.0 headers
+- JSON and Markdown files are excluded (JSON doesn't support comments)
+- Generated files and certain vendor paths are excluded
+- SPI service files (`META-INF/services/`) require headers (use `#` comment style)
+
+## Installation
+
+```bash
+# Same version as CI (pinned commit)
+go install github.com/apache/skywalking-eyes/cmd/license-eye@5b7ee1731d036b5aac68f8bd3fc9e6f98ada082e
+
+# Or via Homebrew (macOS)
+brew install license-eye

+# Run SkyWalking E2E Test
+
+Run an E2E test case using `skywalking-infra-e2e`. The user provides a test case path (e.g., `simple/jdk`, `storage/banyandb`, `alarm`).
+
+## Prerequisites
+
+All tools require **Go** installed. Check `.github/workflows/` for the exact `e2e` commit used in CI.
+
+### e2e CLI
+
+Built from [apache/skywalking-infra-e2e](https://github.com/apache/skywalking-infra-e2e), pinned by commit in CI:
+
+```bash
+# Install the pinned commit
+go install github.com/apache/skywalking-infra-e2e/cmd/e2e@<commit-id>
+
+# Or clone and build locally (useful when debugging the e2e tool itself)
+git clone https://github.com/apache/skywalking-infra-e2e.git
+cd skywalking-infra-e2e
+git checkout <commit-id>
+make build
+# binary is in bin/e2e — add to PATH or copy to $GOPATH/bin
+```
+
+### swctl, yq, and other tools
+
+E2E test cases run pre-install steps (see `setup.steps` in each `e2e.yaml`) that install tools into `/tmp/skywalking-infra-e2e/bin`. When running locally, you need these tools on your PATH.
+
+**swctl** — SkyWalking CLI, used in verify cases to query OAP's GraphQL API. Pinned at `SW_CTL_COMMIT` in `test/e2e-v2/script/env`:
+
+```bash
+# Option 1: Use the install script (same as CI)
+bash test/e2e-v2/script/prepare/setup-e2e-shell/install.sh swctl
+export PATH=/tmp/skywalking-infra-e2e/bin:$PATH
+
+# Option 2: Build from source
+go install github.com/apache/skywalking-cli/cmd/swctl@<SW_CTL_COMMIT>
+```
+
+**yq** — YAML processor, used in verify cases:
+
+```bash
+# Option 1: Use the install script
+bash test/e2e-v2/script/prepare/setup-e2e-shell/install.sh yq
+export PATH=/tmp/skywalking-infra-e2e/bin:$PATH
+
+# Option 2: brew install yq (macOS)
+```
+
+**Other tools** (only needed for specific test cases):
+
+| Tool | Install script | Used by |
+|------|---------------|---------|
+| `kubectl` | `install.sh kubectl` | Kubernetes-based tests |
+| `helm` | `install.sh helm` | Helm chart tests |
+| `istioctl` | `install.sh istioctl` | Istio/service mesh tests |
+| `etcdctl` | `install.sh etcdctl` | etcd cluster tests |
+
+All install scripts are at `test/e2e-v2/script/prepare/setup-e2e-shell/`.
+
+## Steps
+
+### 1. Determine the test case
+
+Resolve the user's argument to a full path under `test/e2e-v2/cases/`. If ambiguous, list matching directories and ask.
+
+```bash
+ls test/e2e-v2/cases/<argument>/e2e.yaml
+```
+
+### 2. Check if rebuild is needed
+
+Compare source file timestamps against the last build:
+
+```bash
+# OAP server changes since last build
+find oap-server apm-protocol -type f \( \
+  -name "*.java" -o -name "*.yaml" -o -name "*.yml" -o \
+  -name "*.json" -o -name "*.xml" -o -name "*.properties" -o \
+  -name "*.proto" \
+\) -newer dist/apache-skywalking-apm-bin.tar.gz 2>/dev/null | head -5
+
+# Test service changes since last build
+find test/e2e-v2/java-test-service -type f \( \
+  -name "*.java" -o -name "*.xml" -o -name "*.yaml" -o -name "*.yml" \
+\) -newer test/e2e-v2/java-test-service/e2e-service-provider/target/*.jar 2>/dev/null | head -5
+```
+
+If files are found, warn the user and suggest rebuilding before running.
+
+### 3. Rebuild if needed (only with user confirmation)
+
+```bash
+# Rebuild OAP
+./mvnw clean flatten:flatten package -Pall -Dmaven.test.skip && make docker
+
+# Rebuild test services
+./mvnw -f test/e2e-v2/java-test-service/pom.xml clean flatten:flatten package
+```
+
+### 4. Run the E2E test
+
+Set required environment variables and run:
+
+```bash
+export SW_AGENT_JDK_VERSION=8
+e2e run -c test/e2e-v2/cases/<case-path>/e2e.yaml
+```
+
+### 5. If the test fails
+
+Do NOT run cleanup immediately. Instead:
+
+1. Check container logs:
+   ```bash
+   docker compose -f test/e2e-v2/cases/<case-path>/docker-compose.yml logs oap
+   docker compose -f test/e2e-v2/cases/<case-path>/docker-compose.yml logs provider
+   ```
+
+2. Run verify separately (can retry after investigation):
+   ```bash
+   e2e verify -c test/e2e-v2/cases/<case-path>/e2e.yaml
+   ```
+
+3. Only cleanup when done debugging:
+   ```bash
+   e2e cleanup -c test/e2e-v2/cases/<case-path>/e2e.yaml
+   ```
+
+## Common test cases
+
+| Shorthand | Path |
+|-----------|------|
+| `simple/jdk` | `test/e2e-v2/cases/simple/jdk/` |
+| `storage/banyandb` | `test/e2e-v2/cases/storage/banyandb/` |
+| `storage/elasticsearch` | `test/e2e-v2/cases/storage/elasticsearch/` |
+| `alarm` | `test/e2e-v2/cases/alarm/` |
+| `log` | `test/e2e-v2/cases/log/` |
+| `profiling/trace` | `test/e2e-v2/cases/profiling/trace/` |

+
+## Slow test tagging
+
+Tests tagged with `@Tag("slow")` are excluded from the normal integration-test job and run separately in the slow-integration-test job. Use this tag for tests that spin up external services (Elasticsearch, etc.) and take significant time.
+
+## CI retry behavior
+
+All three CI jobs retry on failure (run the same command twice with `||`). This handles flaky tests but masks intermittent issues — if a test fails locally, investigate rather than relying on retries.

-### E2E Configuration (e2e.yaml)
-
-Each test case has an `e2e.yaml` with four sections:
-
-```yaml
-setup:
-  env: compose                              # Environment: compose or kind (Kubernetes)
-  file: docker-compose.yml                  # Docker compose file

-```
-
-### Running E2E Tests Locally
-
-**Prerequisites:**
-- Docker and Docker Compose
-- Go (for e2e tool installation)
-
-**Quick Start (run simple/jdk test):**
-```bash
-# 1. Build distribution and Docker image
-./mvnw clean package -Pall -Dmaven.test.skip
-make docker
-
-# 2. Build test services
-./mvnw -f test/e2e-v2/java-test-service/pom.xml clean package
-
-# 3. Run e2e test (SW_AGENT_JDK_VERSION is required)
-SW_AGENT_JDK_VERSION=8 e2e run -c test/e2e-v2/cases/simple/jdk/e2e.yaml
-```
-
-**Step-by-step debugging:**
-```bash
-# Set required environment variable
-export SW_AGENT_JDK_VERSION=8
-
-# Run individual steps instead of full test
-e2e setup -c test/e2e-v2/cases/simple/jdk/e2e.yaml    # Start containers
-e2e trigger -c test/e2e-v2/cases/simple/jdk/e2e.yaml  # Generate traffic
-e2e verify -c test/e2e-v2/cases/simple/jdk/e2e.yaml   # Validate results
-e2e cleanup -c test/e2e-v2/cases/simple/jdk/e2e.yaml  # Stop containers
-```
-
-### E2E CLI Commands
-
-| Command | Description |
-|---------|-------------|
-| `e2e run -c <path>` | Run complete test (setup → trigger → verify → cleanup) |
-| `e2e setup -c <path>` | Start containers and initialize environment |
-| `e2e trigger -c <path>` | Generate test traffic |
-| `e2e verify -c <path>` | Validate results against expected output |
-| `e2e cleanup -c <path>` | Stop and remove containers |
-
-### Common Test Cases
-
-| Category | Path | Description |
-|----------|------|-------------|
-| `simple/jdk` | `test/e2e-v2/cases/simple/jdk/` | Basic Java agent with BanyanDB |
-| `storage/banyandb` | `test/e2e-v2/cases/storage/banyandb/` | BanyanDB storage backend |
-| `storage/elasticsearch` | `test/e2e-v2/cases/storage/elasticsearch/` | Elasticsearch storage |
-| `alarm/` | `test/e2e-v2/cases/alarm/` | Alerting functionality |
-| `profiling/trace` | `test/e2e-v2/cases/profiling/trace/` | Trace profiling |
-| `log/` | `test/e2e-v2/cases/log/` | Log analysis (LAL) |
-
-### Writing E2E Tests
-
-1. **Create test directory** under `test/e2e-v2/cases/<category>/<name>/`
-
-2. **Create docker-compose.yml** extending base services:
-   ```yaml
-   version: '2.1'
-   services:
-     oap:
-       extends:
-         file: ../../../script/docker-compose/base-compose.yml
-         service: oap
-     banyandb:
-       extends:
-         file: ../../../script/docker-compose/base-compose.yml
-         service: banyandb
-   ```
-
-3. **Create e2e.yaml** with setup, trigger, verify sections
-
-4. **Create expected/ directory** with expected YAML outputs for verification
-
-5. **Create verification cases** (e.g., `simple-cases.yaml`) with swctl queries
-
-### Verification with swctl
-
-The `swctl` CLI queries OAP's GraphQL API:
-
-```bash
-# Query service metrics
-swctl --display yaml --base-url=http://${oap_host}:${oap_12800}/graphql \
-  metrics exec --expression=service_resp_time --service-name=e2e-service-provider
-
-# List services
-swctl --display yaml --base-url=http://${oap_host}:${oap_12800}/graphql \
-  service ls
-
-# Query traces
-swctl --display yaml --base-url=http://${oap_host}:${oap_12800}/graphql \
-  trace ls --service-name=e2e-service-provider
-```
-
-### Environment Variables
-
-Key version commits in `test/e2e-v2/script/env`:
-- `SW_AGENT_JAVA_COMMIT` - Java agent version
-- `SW_BANYANDB_COMMIT` - BanyanDB version
-- `SW_CTL_COMMIT` - swctl CLI version
-- `SW_AGENT_*_COMMIT` - Other agent versions (Go, Python, NodeJS, PHP)
-
-### Debugging E2E Tests
-
-**If a test fails, do NOT run cleanup immediately.** Keep containers running to debug:
-
-```bash
-# 1. Setup containers (only once)
-e2e setup -c test/e2e-v2/cases/simple/jdk/e2e.yaml
-
-# 2. Generate traffic
-e2e trigger -c test/e2e-v2/cases/simple/jdk/e2e.yaml
-
-# 3. Verify (can re-run multiple times after fixing issues)
-e2e verify -c test/e2e-v2/cases/simple/jdk/e2e.yaml
-
-# Check container logs to debug failures
-docker compose -f test/e2e-v2/cases/simple/jdk/docker-compose.yml logs oap
-docker compose -f test/e2e-v2/cases/simple/jdk/docker-compose.yml logs provider
-
-# Only cleanup when done debugging
-e2e cleanup -c test/e2e-v2/cases/simple/jdk/e2e.yaml
-```
-
-**Determining if rebuild is needed:**
-
-Compare file timestamps against last package build. If any files changed after package, rebuild is needed:
-```bash
-# Find OAP runtime files modified after package was built
-find oap-server apm-protocol -type f \( \
-  -name "*.java" -o -name "*.yaml" -o -name "*.yml" -o \
-  -name "*.json" -o -name "*.xml" -o -name "*.properties" -o \
-  -name "*.proto" \
-\) -newer dist/apache-skywalking-apm-bin.tar.gz 2>/dev/null
-
-# Find test service files modified after last build (needs service rebuild)
-find test/e2e-v2/java-test-service -type f \( \
-  -name "*.java" -o -name "*.xml" -o -name "*.yaml" -o -name "*.yml" \
-\) -newer test/e2e-v2/java-test-service/e2e-service-provider/target/*.jar 2>/dev/null
-
-# Find test case config files modified after package was built
-find test/e2e-v2/cases -type f \( \
-  -name "*.yaml" -o -name "*.yml" -o -name "*.json" \
-\) -newer dist/apache-skywalking-apm-bin.tar.gz 2>/dev/null
-```
-
-Also compare git commit ID in binary vs current HEAD:
-```bash
-# Commit ID in packaged binary
-unzip -p dist/apache-skywalking-apm-bin/oap-libs/server-starter-*.jar version.properties | grep git.commit.id
-
-# Current HEAD
-git rev-parse HEAD
-```
-
-**If rebuild is needed, stop e2e first:**
-```bash
-# 1. Cleanup running containers
-e2e cleanup -c test/e2e-v2/cases/simple/jdk/e2e.yaml
-
-# 2. Rebuild OAP (if oap-server/apm-protocol files changed)
-./mvnw clean package -Pall -Dmaven.test.skip && make docker
-
-# 3. Rebuild test services (if java-test-service files changed)
-./mvnw -f test/e2e-v2/java-test-service/pom.xml clean package
-
-# 4. Restart e2e
-e2e setup -c test/e2e-v2/cases/simple/jdk/e2e.yaml
-e2e trigger -c test/e2e-v2/cases/simple/jdk/e2e.yaml
-e2e verify -c test/e2e-v2/cases/simple/jdk/e2e.yaml
-```

-## License Checks (skywalking-eyes)
-
-SkyWalking uses [Apache SkyWalking Eyes](https://github.com/apache/skywalking-eyes) for license header and dependency license checks. **License checks must pass before submitting a PR.**
-
-### Installation
-
-```bash
-# Install the same version used in CI
-go install github.com/apache/skywalking-eyes/cmd/license-eye@5b7ee1731d036b5aac68f8bd3fc9e6f98ada082e
-
-# Or via Homebrew (macOS)
-brew install license-eye
-```
-
-### Commands
-
-```bash
-# Check license headers in source files (fast, run before PR)
-license-eye header check
-
-# Fix missing license headers automatically
-license-eye header fix
-
-# Generate LICENSE file from dependencies
-license-eye dependency resolve --summary ./dist-material/release-docs/LICENSE.tpl
-
-# Check if LICENSE file needs update
-git diff -U0 ./dist-material/release-docs/LICENSE
-```
-
-### Configuration
-
-Configuration is in `.licenserc.yaml`:
-- Defines Apache-2.0 license header
-- Lists paths to ignore (e.g., `**/*.md`, `**/*.json`, generated files)
-- Configures dependency license mappings
-
-### CI Behavior
-
-The CI runs on **Linux (ubuntu-latest)** with two checks:
-1. **license-header**: Verifies all source files have proper Apache-2.0 headers
-2. **dependency-license**: Regenerates LICENSE file and fails if it differs from committed version
-
-**Important:** Some dependencies have platform-specific variants (Windows/macOS suffixes). The LICENSE file should reflect Linux dependencies since CI runs on Linux. If `dependency-license` fails and you're on macOS/Windows, ask maintainers to verify before committing LICENSE changes.

+# DSL Compiler Design: ANTLR4 + Javassist
+
+## Overview
+
+SkyWalking OAP server uses four domain-specific languages (DSLs) for telemetry analysis.
+All four share the same compilation tech stack: **ANTLR4** for grammar parsing and **Javassist** for
+runtime bytecode generation.
+
+| DSL | Purpose | Input | Generated Output |
+|-----|---------|-------|-----------------|
+| **OAL** (Observability Analysis Language) | Trace/mesh metrics aggregation | `.oal` script files | Metrics classes, builders, dispatchers |
+| **MAL** (Meter Analysis Language) | Meter/metrics expression evaluation | YAML config `exp` fields | `MalExpression` implementations |
+| **LAL** (Log Analysis Language) | Log processing pipelines | YAML config `filter` blocks | `LalExpression` implementations |
+| **Hierarchy Matching Rules** | Service hierarchy relationship matching | YAML config expressions | `BiFunction<Service, Service, Boolean>` implementations |
+
+## Compilation Pipeline
+
+All four DSLs follow the same three-phase compilation pipeline at OAP startup:
+
+```
+DSL string (from .oal script or YAML config)
+    |
+    v
+Phase 1: ANTLR4 Parsing
+    Lexer + Parser (generated from .g4 grammars at build time)
+    → Immutable AST model
+    |
+    v
+Phase 2: Java Source Generation
+    Walk AST model, emit Java source code as strings
+    |
+    v
+Phase 3: Javassist Bytecode Generation
+    ClassPool.makeClass() → CtClass → addMethod(source) → toClass()
+    → Ready-to-use class instance loaded into JVM
+```
+
+### What Each DSL Generates
+
+| DSL | Interface / Base Class | Key Method |
+|-----|----------------------|------------|
+| OAL | Extends metrics function class (e.g., `LongAvgMetrics`) | `id()`, `serialize()`, `deserialize()`, plus dispatcher `dispatch(source)` |
+| MAL metric | `MalExpression` | `SampleFamily run(Map<String, SampleFamily> samples)` |
+| MAL filter | `Predicate<Map<String, String>>` | `boolean test(Map<String, String> tags)` |
+| LAL | `LalExpression` | `void execute(FilterSpec filterSpec, ExecutionContext ctx)` |
+| Hierarchy | `BiFunction<Service, Service, Boolean>` | `Boolean apply(Service upper, Service lower)` |
+
+OAL is the most complex -- it generates **three classes per metric** (metrics class with storage annotations,
+metrics builder for serialization, and source dispatcher for routing), whereas MAL/LAL/Hierarchy each generate
+a single functional class per expression.
+
+## ANTLR4 Grammars
+
+Each DSL has its own ANTLR4 lexer and parser grammar. The Maven ANTLR4 plugin generates Java lexer/parser
+classes at build time; these are then used at runtime to parse DSL strings.
+
+| DSL | Grammar Location |
+|-----|-----------------|
+| OAL | `oap-server/oal-grammar/src/main/antlr4/.../OALLexer.g4`, `OALParser.g4` |
+| MAL | `oap-server/analyzer/meter-analyzer/src/main/antlr4/.../MALLexer.g4`, `MALParser.g4` |
+| LAL | `oap-server/analyzer/log-analyzer/src/main/antlr4/.../LALLexer.g4`, `LALParser.g4` |
+| Hierarchy | `oap-server/analyzer/hierarchy/src/main/antlr4/.../HierarchyRuleLexer.g4`, `HierarchyRuleParser.g4` |
+
+## Javassist Constraints
+
+Javassist compiles Java source strings into bytecode but has limitations that shape the code generation:
+
+- **No anonymous inner classes or lambdas** -- Callback-based APIs require workarounds.
+  LAL uses private methods called directly from `execute()` instead of Consumer callbacks.
+  OAL pre-compiles callbacks as separate `CtClass` instances where needed.
+- **No generics in method bodies** -- Generated source uses raw types with explicit casts.
+- **Class loading anchor** -- Each DSL uses a `PackageHolder` marker class so that
+  `ctClass.toClass(PackageHolder.class)` loads the generated class into the correct module/package
+  (required for JDK 9+ module system).
+
+OAL additionally uses **FreeMarker templates** to generate method bodies for metrics classes, builders, and
+dispatchers, since these classes are more complex and benefit from template-driven generation.

+    agent-analyzer/       # Calls MAL compiler for meter data
+```
+
+OAL keeps grammar and runtime in separate modules (`oal-grammar` and `oal-rt`) because `server-core`
+depends on the grammar while the runtime implementation depends on `server-core` (avoiding circular
+dependency). MAL, LAL, and Hierarchy are each self-contained in a single module.
+
+## Groovy Replacement (MAL, LAL, Hierarchy)
+
+Reference: [Discussion #13716](https://github.com/apache/skywalking/discussions/13716)
+
+MAL, LAL, and Hierarchy previously used **Groovy** as the runtime scripting engine. OAL has always used
+ANTLR4 + Javassist. The Groovy-based DSLs were replaced for the following reasons:
+
+1. **Startup cost** -- 1,250+ `GroovyShell.parse()` calls at OAP boot, each spinning up the full Groovy
+   compiler pipeline.
+
+2. **Runtime execution overhead** -- MAL expressions execute on every metrics ingestion cycle. Per-expression
+   overhead from dynamic Groovy compounds at scale: property resolution through 4+ layers of indirection,
+   `ExpandoMetaClass` closure allocation for simple arithmetic, and megamorphic call sites that defeat JIT
+   optimization.
+
+3. **Late error detection** -- MAL uses dynamic Groovy; typos in metric names or invalid method chains are
+   only discovered when that specific expression runs with real data.
+
+4. **Debugging complexity** -- Stack traces include Groovy MOP internals (`CallSite`, `MetaClassImpl`,
+   `ExpandoMetaClass`), obscuring the actual expression logic.
+
+5. **GraalVM incompatibility** -- `invokedynamic` bootstrapping and `ExpandoMetaClass` are fundamentally
+   incompatible with ahead-of-time (AOT) compilation, blocking the
+   [GraalVM native-image distribution](https://github.com/apache/skywalking-graalvm-distro).
+
+The DSL grammar for users remains **100% unchanged** -- the same expressions written in YAML config files
+work exactly as before. Only the internal compilation engine was replaced.
+
+### Verification: Groovy v1 Checker
+
+To ensure the new Java compilers produce identical results to the original Groovy implementation,
+a **dual-path comparison test suite** is maintained under `test/script-cases/`:
+
+```
+test/script-cases/
+  scripts/
+    mal/                      # Copies of shipped MAL configs (test-otel-rules, test-meter-analyzer-config, etc.)
+    lal/                      # Copies of shipped LAL scripts (test-lal/)
+    hierarchy-rule/           # Copy of shipped hierarchy-definition.yml
+  script-runtime-with-groovy/
+    mal-v1-with-groovy/       # MAL v1: original Groovy-based implementation
+    lal-v1-with-groovy/       # LAL v1: original Groovy-based implementation
+    hierarchy-v1-with-groovy/ # Hierarchy v1: original Groovy-based implementation
+    mal-lal-v1-v2-checker/    # Runs every MAL/LAL expression through BOTH v1 and v2, compares results
+    hierarchy-v1-v2-checker/  # Runs every hierarchy rule through BOTH v1 and v2, compares results
+```
+
+The checker mechanism:
+
+1. Loads all test copies of production YAML config files from `test/script-cases/scripts/`
+2. For each DSL expression, compiles with **both** v1 (Groovy) and v2 (ANTLR4 + Javassist)
+3. Compares the results:
+   - **MAL**: Two-level comparison for each expression:
+     1. **Metadata comparison** -- sample names, aggregation labels, downsampling type, percentile config
+     2. **Runtime execution comparison** -- builds mock `SampleFamily` input data from `ExpressionMetadata`,
+        executes with both v1 and v2, compares output samples (count, labels, values with epsilon).
+        For `increase()`/`rate()` expressions, the `CounterWindow` is primed with an initial run before
+        comparing the second run's output.
+   - **LAL**: Runtime execution comparison -- both v1 and v2 execute with mock LogData,
+     then compare execution state (service, layer, tags, abort/save flags).
+     For rules requiring extraLog (e.g., envoy-als), mock proto data is built from `.input.data` files
+     and the `LALSourceTypeProvider` SPI resolves the proto type per layer.
+     Test scripts include both copies of production configs (`oap-cases/`) and
+     dedicated feature-coverage rules (`feature-cases/`).
+   - **Hierarchy**: Compare `BiFunction` evaluation with test Service pairs
+
+This ensures 100% behavioral parity. The Groovy v1 modules are **test-only dependencies** -- they are not
+included in the OAP distribution.

+# Claude Code Skills for SkyWalking Development
+
+[Claude Code](https://docs.anthropic.com/en/docs/claude-code) is Anthropic's CLI tool for AI-assisted coding.
+This project provides a set of Claude Code skills (slash commands) that automate common development workflows.
+
+**Note**: These skills are specific to Claude Code. They are defined in the `.claude/skills/` directory
+and are not recognized by other AI coding tools.
+
+## Available Skills
+
+| Skill | Command | Description |
+|-------|---------|-------------|
+| Compile | `/compile [all\|backend\|javadoc\|checkstyle\|module-name]` | Build the OAP server, run javadoc checks, or verify checkstyle |
+| Test | `/test [unit\|integration\|slow\|module-name]` | Run unit tests, integration tests, or slow integration tests matching CI |
+| License | `/license [check\|fix\|deps]` | Check and fix Apache 2.0 license headers and dependency licenses |
+| Pull Request | `/gh-pull-request` | Commit, push, and create a PR with pre-flight checks (compile, checkstyle, license headers) |
+| E2E Debug | `/ci-e2e-debug <RUN_ID or URL>` | Download and inspect CI e2e test logs from GitHub Actions artifacts |
+| Generate Classes | `/generate-classes <mal\|oal\|lal\|hierarchy\|all>` | Generate bytecode classes from DSL scripts for inspection |
+| Run E2E | `/run-e2e [test-case-path]` | Run SkyWalking e2e tests locally |
+
+## Typical Workflow
+
+1. Make your code changes.
+2. Run `/compile` to verify the build passes.
+3. Run `/test` to run relevant tests.
+4. Run `/license check` to verify license headers.
+5. Run `/gh-pull-request` to commit, push, and open a PR.
+
+If a CI e2e test fails after pushing, use `/ci-e2e-debug <RUN_ID>` to download and inspect the logs.

+# Dynamic Code Generation and Debugging
+
+SkyWalking OAP server uses four Domain-Specific Languages (DSLs) to define observability logic:
+**OAL** (traces/mesh metrics), **MAL** (meter metrics), **LAL** (log analysis), and **Hierarchy** (service matching rules).
+These DSL scripts are compiled into JVM bytecode when the OAP server starts.
+The generated classes run in-process — there are no intermediate source files.
+
+When a runtime error occurs inside these generated classes, the stack trace references class names and
+source locations that map back to the original DSL configuration files.
+This document explains how to dump the generated bytecode to disk for inspection and how to read the
+error messages.
+
+## DSL Configuration Files
+
+| DSL | Config Location | What It Generates |
+|-----|----------------|-------------------|
+| OAL | `config/*.oal` | Metrics, MetricsBuilder, and Dispatcher classes per metric definition |
+| MAL | `config/meter-analyzer-config/*.yaml`, `config/otel-rules/**`, `config/envoy-metrics-rules/*.yaml` | One class per metric expression |
+| LAL | `config/lal/*.yaml` | One class per log filter rule |
+| Hierarchy | `config/hierarchy-definition.yml` | One class per auto-matching rule |
+
+All paths are relative to the OAP distribution root directory.
+
+## Dumping Generated Classes
+
+Set the environment variable `SW_DYNAMIC_CLASS_ENGINE_DEBUG` to any non-empty value before starting the OAP server.
+All four DSL compilers check this variable and dump `.class` files to disk when it is set.
+
+```shell
+# Binary distribution
+export SW_DYNAMIC_CLASS_ENGINE_DEBUG=Y
+bin/oapService.sh
+```
+
+```shell
+# Docker
+docker run -e SW_DYNAMIC_CLASS_ENGINE_DEBUG=Y ... apache/skywalking-oap-server
+```
+
+```yaml
+# Kubernetes (in container env section)
+env:
+  - name: SW_DYNAMIC_CLASS_ENGINE_DEBUG
+    value: "Y"
+```
+
+### Output Directory Structure
+
+The generated `.class` files are written to sibling directories next to `oap-libs/`:
+
+**Binary distribution** (`apache-skywalking-apm-bin/`):
+```
+apache-skywalking-apm-bin/
+├── config/                   ← DSL source scripts (*.oal, *.yaml, *.yml)
+├── oap-libs/                 ← OAP server jars
+├── oal-rt/                   ← Generated OAL classes
+│   ├── metrics/              ←   e.g., ServiceRespTimeMetrics.class
+│   ├── metrics/builder/      ←   e.g., ServiceRespTimeMetricsBuilder.class
+│   └── dispatcher/           ←   e.g., ServiceDispatcher.class
+├── mal-rt/                   ← Generated MAL classes (e.g., meter_vm_cpu_total_percentage.class)
+├── lal-rt/                   ← Generated LAL classes (e.g., default_default.class)
+└── hierarchy-rt/             ← Generated Hierarchy classes (e.g., name.class)
+```
+
+**Docker** (`/skywalking/`):
+```
+/skywalking/
+├── config/
+├── oap-libs/
+├── oal-rt/
+├── mal-rt/
+├── lal-rt/
+└── hierarchy-rt/
+```
+
+The OAL output directories are cleaned on each restart. MAL, LAL, and Hierarchy directories are created
+on demand if they don't exist.
+
+### Inspecting Generated Classes
+
+Use `javap` to decompile a generated `.class` file:
+
+```shell
+javap -v -p oal-rt/metrics/ServiceRespTimeMetrics.class
+```
+
+The output includes:
+- **SourceFile attribute** — shows the DSL source file and the generated class name.
+- **LineNumberTable** — maps bytecode offsets to statement numbers, used by the JVM in stack traces.
+- **LocalVariableTable** — shows named local variables for readability.
+
+## Reading Error Stack Traces
+
+When a runtime error occurs inside a generated class, the JVM prints a stack trace that combines the
+`SourceFile` attribute and the `LineNumberTable`. The format is:
+
+```
+at <package>.<ClassName>.<method>(SourceFile:LineNumber)
+```
+
+The `SourceFile` attribute encodes the original DSL configuration file in parentheses:
+
+```
+(<dsl_source_file>:<rule_line_or_index>)<GeneratedClassName>.java
+```
+
+### Example Stack Trace
+
+```
+java.lang.ArithmeticException: / by zero
+    at ...metrics.generated.ServiceRespTimeMetrics.id0((core.oal:20)ServiceRespTimeMetrics.java:3)
+    at ...worker.MetricsStreamProcessor.in(MetricsStreamProcessor.java:...)
+    ...
+```
+
+Reading this:
+- `(core.oal:20)` — the error originates from OAL file `core.oal`, line 20
+- `ServiceRespTimeMetrics.java` — the generated class for metric `ServiceRespTime`
+- `:3` — statement 3 within the generated `id0` method
+
+### Format Per DSL
+
+| DSL | SourceFile Example | How to Read |
+|-----|-------------------|-------------|
+| OAL | `(core.oal:20)ServiceRespTimeMetrics.java` | OAL file `core.oal`, line 20 defines this metric |
+| MAL | `(spring-sleuth.yaml:3)cluster_up_rq_incr.java` | YAML file `spring-sleuth.yaml`, rule index 3 (0-based, the 4th `metricsRules` entry) |
+| LAL | `(default.yaml)default_default.java` | YAML file `default.yaml`, rule named `default_default` |
+| Hierarchy | `(hierarchy-definition.yml)name.java` | Rule `name` in `hierarchy-definition.yml` |
+
+**Notes:**
+- The number after `:` in the MAL source prefix is the 0-based index of the rule within the `metricsRules` list in that YAML file.
+- LAL and Hierarchy rules are standalone entries, so the source prefix contains only the YAML file name without a line number.
+- When source information is unavailable, the SourceFile falls back to just `ClassName.java` without the parenthesized prefix.
+
+### Mapping Back to DSL Source
+
+1. **Identify the DSL type** from the package or class suffix:
+   - `...metrics.generated.*Metrics` or `...Dispatcher` → OAL
+   - `...meter.analyzer.v2.compiler.rt.MalExpr_*` → MAL
+   - `...log.analyzer.v2.compiler.rt.LalExpr_*` → LAL
+   - `...hierarchy.rule.rt.*` → Hierarchy
+
+2. **Find the source file** from the parenthesized prefix (e.g., `core.oal`, `spring-sleuth.yaml`).
+   These files are in the `config/` directory.
+
+3. **Locate the rule** using the line number (OAL) or rule index (MAL) or rule name (LAL/Hierarchy).
+
+4. **Use the statement number** (after the last `:`) as a rough indicator of which operation within the
+   generated method failed. Dump the class (see above) and use `javap -v` to see the exact mapping.
+
+## Common Error Patterns
+
+### OAL Compilation Failure
+
+OAL compilation errors are logged at `ERROR` level during OAP startup:
+
+```
+ERROR o.a.s.o.v.g.OALClassGeneratorV2 - Can't generate method id for ServiceRespTimeMetrics.
+```
+
+This indicates that the generated Java source for the `id` method failed to compile.
+Check the OAL script syntax at the reported metric name.
+
+### MAL/LAL Runtime Error
+
+MAL and LAL errors during metric processing are caught and logged per-expression:
+
+```
+ERROR o.a.s.o.m.a.v.MetricConvert - Analyze Analyzer{...} error
+java.lang.NullPointerException
+    at ...MalExpr_5.run((vm.yaml:2)meter_vm_cpu_total_percentage.java:5)
+```
+
+This tells you: the error is in `vm.yaml`, rule index 2 (the 3rd `metricsRules` entry),
+metric `meter_vm_cpu_total_percentage`, at statement 5 of the generated `run()` method.
+The processing continues for other metrics — a single expression failure does not crash the server.
+
+### Hierarchy Compilation Failure
+
+Hierarchy rule compilation errors are thrown at startup:
+
+```
+IllegalStateException: Failed to compile hierarchy rule: lower-short-name-remove-namespace,
+    expression: { (u, l) -> { if (...) { ... } } }
+```
+
+Check the rule expression syntax in `config/hierarchy-definition.yml` under `auto-matching-rules`.

+# Hierarchy Rule Compiler
+
+Compiles hierarchy matching rule expressions into `BiFunction<Service, Service, Boolean>` implementation classes at runtime using ANTLR4 parsing and Javassist bytecode generation.
+
+## Compilation Workflow
+
+```
+Rule expression string  (e.g., "{ (u, l) -> u.name == l.name }")
+  → HierarchyRuleScriptParser.parse(expression)   [ANTLR4 lexer/parser → visitor]
+  → HierarchyRuleModel (immutable AST)
+  → HierarchyRuleClassGenerator.compile(ruleName, expression)
+      1. classPool.makeClass()         — create class implementing BiFunction
+      2. generateApplyMethod(model)    — emit Java source for apply(Object, Object)
+      3. ctClass.toClass(HierarchyRulePackageHolder.class) — load via package anchor
+  → BiFunction<Service, Service, Boolean> instance
+```
+
+The generated class implements:
+```java
+Object apply(Object arg0, Object arg1)
+  // cast internally to Service and returns Boolean
+```
+
+No separate consumer/closure classes are needed — hierarchy rules are simple enough to compile into a single method body.
+
+## File Structure

+
+## Package & Class Naming
+
+| Component | Package / Name |
+|-----------|---------------|
+| Parser/Model/Generator | `org.apache.skywalking.oap.server.core.config.v2.compiler` |
+| Generated classes | `org.apache.skywalking.oap.server.core.config.v2.compiler.hierarchy.rule.rt.HierarchyRule_<N>` |
+| Package holder | `org.apache.skywalking.oap.server.core.config.v2.compiler.hierarchy.rule.rt.HierarchyRulePackageHolder` |
+| SPI provider | `org.apache.skywalking.oap.server.core.config.v2.compiler.CompiledHierarchyRuleProvider` |
+| Service type | `org.apache.skywalking.oap.server.core.query.type.Service` (in server-core) |
+
+`<N>` is a global `AtomicInteger` counter.
+
+## Code Generation Details
+
+**Field access mapping**: Property access in expressions maps to getter methods:
+- `u.name` → `u.getName()`
+- `l.shortName` → `l.getShortName()`
+- Generic: `x.foo` → `x.getFoo()`
+
+**Comparison operators**: `==` and `!=` use `java.util.Objects.equals()`. Numeric comparisons (`>`, `<`, `>=`, `<=`) emit direct operators.
+
+**Method chains**: `l.shortName.substring(0, l.shortName.lastIndexOf("."))` generates chained Java method calls directly.
+
+## Example
+
+**Input**: `{ (u, l) -> u.name == l.name }`
+
+**Generated `apply()` method**:
+```java
+public Object apply(Object arg0, Object arg1) {
+  Service u = (Service) arg0;
+  Service l = (Service) arg1;
+  return Boolean.valueOf(java.util.Objects.equals(u.getName(), l.getName()));
+}
+```
+
+**Input with block body**: `{ (u, l) -> { if (l.shortName.lastIndexOf(".") > 0) { return u.name == l.shortName.substring(0, l.shortName.lastIndexOf(".")); } return false; } }`
+
+**Generated `apply()` method**:
+```java
+public Object apply(Object arg0, Object arg1) {
+  Service u = (Service) arg0;
+  Service l = (Service) arg1;
+  if (l.getShortName().lastIndexOf(".") > 0) {
+    return Boolean.valueOf(
+        java.util.Objects.equals(
+            u.getName(),
+            l.getShortName().substring(0, l.getShortName().lastIndexOf("."))));
+  }
+  return Boolean.valueOf(false);
+}
+```
+
+## Rule Patterns
+
+Four rule types are defined in `hierarchy-definition.yml`:
+
+| Rule Name | Expression Pattern |
+|-----------|-------------------|
+| `name` | `{ (u, l) -> u.name == l.name }` |
+| `short-name` | `{ (u, l) -> u.shortName == l.shortName }` |
+| `lower-short-name-remove-namespace` | `{ (u, l) -> { if (l.shortName.lastIndexOf(".") > 0) { return u.name == l.shortName.substring(0, l.shortName.lastIndexOf(".")); } return false; } }` |
+| `lower-short-name-with-fqdn` | `{ (u, l) -> u.shortName == l.shortName.concat("." + u.shortName) }` |
+
+## Hierarchy Input Data Mock Principles
+
+Hierarchy rules are simpler than MAL/LAL — they take two `Service` objects and return a boolean. The test data is implicit in the test code rather than YAML files.
+
+### Principles
+
+1. **Service objects are the input**: Each rule receives `(Service upper, Service lower)` and returns whether they match. Test data is built programmatically with `Service.builder().name("...").shortName("...").build()`.
+2. **Four rule patterns**: See "Rule Patterns" above. Tests cover all four with various `name`/`shortName` combinations.
+3. **v1-v2 comparison**: The checker test (`HierarchyComparisonTest` in `mal-lal-v1-v2-checker`) compiles each rule with both v1 (Groovy) and v2 (ANTLR4), runs them on the same `Service` pairs, and asserts identical results.
+4. **No `.data.yaml` files**: Hierarchy rules are purely functional (two inputs → boolean), so mock data is inline in tests.
+
+## Debug Output
+
+When `SW_DYNAMIC_CLASS_ENGINE_DEBUG=true` environment variable is set, generated `.class` files are written to disk for inspection:
+
+```
+{skywalking}/hierarchy-rt/
+  *.class          - Generated HierarchyRule .class files
+```
+
+This is the same env variable used by OAL. Useful for debugging code generation issues. In tests, use `setClassOutputDir(dir)` instead.
+
+## Dependencies
+
+Grammar, compiler, and runtime are merged into this module:
+- ANTLR4 grammar → generates lexer/parser at build time
+- `server-core` — `Service` type
+- `javassist` — bytecode generation

+# LAL Compiler
+
+Compiles LAL (Log Analysis Language) scripts into `LalExpression` implementation classes at runtime using ANTLR4 parsing and Javassist bytecode generation.
+
+## Compilation Workflow
+
+```
+LAL DSL string
+  → LALScriptParser.parse(dsl)                 [ANTLR4 lexer/parser → listener]
+  → LALScriptModel (immutable AST)
+  → LALClassGenerator.compileFromModel(model)
+      1. detectParserType(model)     — compile-time data source analysis (JSON/YAML/TEXT/NONE)
+      2. generateExecuteMethod()     — emit execute() + private methods (_extractor, _sink)
+      3. classPool.makeClass()       — single class implementing LalExpression
+      4. addLocalVariableTable()     — named LVT entries for all methods
+      5. ctClass.toClass()           — load into JVM
+  → LalExpression instance
+```
+
+The generated class implements:
+```java
+void execute(FilterSpec filterSpec, ExecutionContext ctx)
+```

+
+## Package & Class Naming
+
+All v2 classes live under `org.apache.skywalking.oap.log.analyzer.v2.*` to avoid FQCN conflicts with the v1 (Groovy) classes.
+
+| Component | Package / Name |
+|-----------|---------------|
+| Parser/Model/Generator | `org.apache.skywalking.oap.log.analyzer.v2.compiler` |
+| Generated classes | `org.apache.skywalking.oap.log.analyzer.v2.compiler.rt.LalExpr_<N>` |
+| Package holder | `org.apache.skywalking.oap.log.analyzer.v2.compiler.rt.LalExpressionPackageHolder` |
+| Runtime helper | `org.apache.skywalking.oap.log.analyzer.v2.compiler.rt.LalRuntimeHelper` |
+| Functional interface | `org.apache.skywalking.oap.log.analyzer.v2.dsl.LalExpression` |
+
+`<N>` is a global `AtomicInteger` counter.
+
+## Single Class with Private Methods
+
+The generator produces a single class per LAL script. Extractor and sink blocks become private methods called directly from `execute()` — no Consumer classes, no callback indirection.
+
+Method naming: `_extractor`, `_extractor_2`, `_extractor_3` (no `_0` suffix for single methods).
+
+Sub-blocks (slowSql, sampledTrace, metrics, sampler, rateLimit) are inlined within their parent method.
+
+## Explicit Context Passing (No ThreadLocal)
+
+All spec methods take `ExecutionContext ctx` as an explicit parameter — there is no `BINDING` ThreadLocal or `bind()` method. The `execute()` method receives `ctx` directly and passes it through:
+
+- `execute(FilterSpec filterSpec, ExecutionContext ctx)` — entry point
+- `filterSpec.json(ctx)`, `filterSpec.text(ctx)`, `filterSpec.sink(ctx)` — parser/sink calls
+- `_e.service(h.ctx(), ...)`, `_e.tag(h.ctx(), ...)` — extractor calls via `h.ctx()`
+- `_f.sampler().rateLimit(h.ctx(), ...)` — sink calls via `h.ctx()`
+
+The generated `execute()` method guards `_extractor()` and `_sink()` calls with `if (!ctx.shouldAbort())`, matching v1 Groovy behavior where `extractor {}` and `sink {}` closures check the abort flag before running their body. `finalizeSink(ctx)` also checks the flag. Individual spec methods inside each block additionally check `ctx.shouldAbort()` as a defense-in-depth measure.
+
+## LocalVariableTable (LVT)
+
+All generated methods include a `LocalVariableTable` attribute for debugger/decompiler readability. Without LVT, tools show `var0`, `var1`, `var2`, `var3` instead of named variables.
+
+| Method | Slot 0 | Slot 1 | Slot 2 | Slot 3 |
+|--------|--------|--------|--------|--------|
+| `execute()` | `this` | `filterSpec` | `ctx` | `h` |
+| `_extractor()` | `this` | `_e` | `h` | — |
+| `_sink()` | `this` | `_f` | `h` | — |
+
+LVT entries are added via `PrivateMethod` inner class which carries both source code and variable descriptors.
+
+## Compile-Time Data Source Analysis
+
+The generator detects the parser type from the AST at compile time and generates typed value access:
+
+| Parser Type | LAL Example | Generated Code |
+|---|---|---|
+| JSON/YAML | `parsed.service` | `h.mapVal("service")` |
+| JSON/YAML nested | `parsed.a.b` | `h.mapVal("a", "b")` |
+| TEXT (regexp) | `parsed.level` | `h.group("level")` |
+| NONE + extraLogType | `parsed.response.code` | `((ExtraLogType) h.ctx().extraLog()).getResponse().getCode()` |
+| NONE + no extraLogType | `parsed.service` | `h.ctx().log().getService()` (LogData.Builder fallback) |
+| log fields | `log.service` | `h.ctx().log().getService()` |
+| log trace | `log.traceContext.traceId` | `h.ctx().log().getTraceContext().getTraceId()` |
+| tags | `tag("KEY")` | `h.tagValue("KEY")` |
+
+### extraLogType and LALSourceTypeProvider SPI
+
+For LAL rules with no DSL parser (`json{}`/`yaml{}`/`text{}`), the compiler needs a type to generate direct getter calls on `parsed.*` fields. Per-rule resolution order:
+
+1. **DSL parser** (`json{}`, `yaml{}`, `text{}`) — parser wins, extraLogType is ignored
+2. **Explicit `extraLogType`** in YAML rule config — FQCN string, resolved via `Class.forName()`
+3. **`LALSourceTypeProvider` SPI** — default extraLogType for a layer, discovered via `ServiceLoader`
+4. **`LogData.Builder` fallback** — if none of the above, `parsed.*` generates getter chains on `LogData.Builder` with compile-time reflection validation. Fields not found on `LogData.Builder` cause `IllegalArgumentException` at boot.
+
+The SPI interface is in `org.apache.skywalking.oap.log.analyzer.v2.spi.LALSourceTypeProvider`. Receiver plugins implement it and register in `META-INF/services/`. Example: `EnvoyHTTPLALSourceTypeProvider` registers `HTTPAccessLogEntry` for `Layer.MESH`.
+
+A single YAML file can have rules with different input types (e.g., `envoy-als.yaml` has a proto-based rule and a `json{}` rule, both in layer MESH). Resolution is per-rule, not per-file.
+
+## Example
+
+**Input**: `filter { json {} extractor { service parsed.service as String } sink {} }`
+
+One class is generated:
+
+```java
+public class LalExpr_0 implements LalExpression {
+    public void execute(FilterSpec filterSpec, ExecutionContext ctx) {
+        LalRuntimeHelper h = new LalRuntimeHelper(ctx);
+        filterSpec.json(ctx);
+        if (!ctx.shouldAbort()) {
+            _extractor(filterSpec.extractor(), h);
+        }
+        filterSpec.sink(ctx);
+    }
+    private void _extractor(ExtractorSpec _e, LalRuntimeHelper h) {
+        _e.service(h.ctx(), h.toStr(h.mapVal("service")));
+    }
+}
+```
+
+## Runtime Helper (LalRuntimeHelper)
+
+Instance-based helper created at the start of `execute()`, holds the `ExecutionContext`.
+
+**Data source methods:**
+- `mapVal(key)`, `mapVal(k1, k2)`, `mapVal(k1, k2, k3)` — JSON/YAML map access
+- `group(name)` — text regexp named group
+- `tagValue(key)` — log tag lookup
+- `ctx()` — access to ExecutionContext (for `h.ctx().log()` proto getters)
+
+**Type conversion:** `toStr()`, `toLong()`, `toInt()`, `toBool()`
+
+**Boolean evaluation:** `isTrue()`, `isNotEmpty()`
+
+**Safe navigation:** `toString()`, `trim()`
+
+## JSON/YAML LogData Field Population
+
+When `json{}` or `yaml{}` parses the log body, `FilterSpec` also adds LogData proto fields
+(`service`, `serviceInstance`, `endpoint`, `layer`, `timestamp`) to the parsed map via
+`putIfAbsent`. Body-parsed values take priority; proto fields serve as fallback. This matches
+v1 Groovy `Binding.Parsed.getAt(key)` behavior where `parsed.service` falls back to
+`LogData.getService()` when the JSON body doesn't contain a `service` key.
+
+## Null-Safe String Conversion
+
+Generated code calls `h.toStr()` instead of `String.valueOf()` for casting parsed values to String.
+This preserves Java `null` for missing fields (matching Groovy's `null as String` → `null` behavior),
+whereas `String.valueOf(null)` would produce the string `"null"`.
+
+## Data-Driven Execution Tests
+
+`LALExpressionExecutionTest` loads LAL rules from YAML and mock input from `.input.data` files:
+
+```
+test/script-cases/scripts/lal/test-lal/
+  oap-cases/                     — copies of shipped LAL configs (each with .input.data)
+  feature-cases/
+    execution-basic.yaml         — 17 LAL feature-coverage rules
+    execution-basic.input.data   — mock input + expected output per rule
+```
+
+Each `.input.data` entry specifies `body-type`, `body`, optional `tags`, and `expect` assertions
+(service, instance, endpoint, layer, tags, abort, save, timestamp, sampledTrace fields).
+
+## LAL Input Data Mock Principles
+
+LAL test data lives in `.input.data` files alongside rule YAML files under `test/script-cases/scripts/lal/`. Each entry describes one log to process and the expected output.
+
+### Input Entry Structure
+
+```yaml
+rule-name:
+  - service: test-svc               # LogData.service
+    instance: test-inst              # LogData.serviceInstance (optional)
+    body-type: json|yaml|text|none   # How to parse the body
+    body: '{"key": "value"}'         # Log body string
+    trace-id: trace-001              # Trace context (optional)
+    timestamp: 1609459200000         # LogData.timestamp (optional)
+    tags:                            # LogData tags (optional)
+      LOG_KIND: NET_PROFILING_SAMPLED_TRACE
+    extra-log:                       # For proto-typed rules (e.g., envoy-als)
+      proto-class: io.envoyproxy.envoy.data.accesslog.v3.HTTPAccessLogEntry
+      proto-json: '{"response":{"responseCode":500}}'
+    expect:                          # Expected output assertions
+      save: true                     # SinkSpec.save() called
+      abort: false                   # Not aborted
+      service: expected-svc          # Extracted service name
+      layer: MESH                    # Extracted layer
+      tag.status.code: "500"         # Extracted tag value
+      sampledTrace.traceId: trace-001  # SampledTrace field
+```
+
+### Principles
+
+1. **`body-type` determines parsing**: `json` → `json{}` block, `text` → `text{}` block, `none` → proto extraLog or raw LogData access.
+2. **`extra-log` for proto types**: When rules access `parsed.*` on protobuf types (e.g., `HTTPAccessLogEntry`), provide `proto-class` and `proto-json`. The test harness parses via `JsonFormat`.
+3. **`expect` section is mandatory**: Every entry must have `expect` with at least `save` and `abort`.
+4. **Enum fields as strings**: Fields like `sampledTrace.reason` and `sampledTrace.detectPoint` are enums. Expected values use enum names (e.g., `slow`, `client`) compared via `.name()`.
+5. **Tag assertions**: `tag.KEY` in expect asserts extracted tag values (e.g., `tag.status.code: "500"`).
+6. **SampledTrace assertions**: `sampledTrace.FIELD` asserts fields on `NativeSampledTrace` (traceId, processId, destProcessId, componentId, etc.).
+7. **v1 is the truth**: Both v1 (Groovy) and v2 (ANTLR4) must produce identical results. If v1 produces different output than expected, the expected data has a bug.
+
+### Directory Structure
+
+```
+test/script-cases/scripts/lal/test-lal/
+  oap-cases/                     — copies of shipped LAL configs
+    default.yaml / default.input.data
+    envoy-als.yaml / envoy-als.input.data
+    ...
+  feature-cases/
+    execution-basic.yaml / execution-basic.input.data  — LAL feature tests
+```
+
+## Debug Output
+
+When `SW_DYNAMIC_CLASS_ENGINE_DEBUG=true` environment variable is set, generated `.class` files are written to disk for inspection:
+
+```
+{skywalking}/lal-rt/
+  *.class          - Generated LalExpression .class files
+```
+
+This is the same env variable used by OAL. Useful for debugging code generation issues or comparing V1 vs V2 output. In tests, use `setClassOutputDir(dir)` instead.
+
+## Dependencies
+
+All within this module (grammar, compiler, and runtime are merged):
+- ANTLR4 grammar → generates lexer/parser at build time
+- `LalExpression`, `ExecutionContext`, `FilterSpec`, all Spec classes — in `dsl` package of this module
+- `javassist` — bytecode generation

+/**
+ * Runtime helper for compiled LAL expressions.
+ *
+ * <p>Created once per {@code execute()} call, holds the {@link ExecutionContext}
+ * and provides data-source-specific access and type conversion methods.
+ *
+ * <h2>Data Source Methods</h2>
+ *
+ * <p><b>1. JSON/YAML map data</b> — used when the LAL script has a {@code json {}} or
+ * {@code yaml {}} parser. The parsed body is stored in {@code ctx.parsed().getMap()}.
+ * <pre>
+ *   // LAL:  parsed.service as String
+ *   // Generated:  h.toStr(h.mapVal("service"))
+ *
+ *   // LAL:  parsed.client_process.address as String  (nested map)
+ *   // Generated:  h.toStr(h.mapVal("client_process", "address"))
+ * </pre>
+ *
+ * <p><b>2. Text regexp matcher data</b> — used when the LAL script has a
+ * {@code text { regexp '...' }} parser. The parsed body is stored as a
+ * {@link java.util.regex.Matcher} in {@code ctx.parsed().getMatcher()}.
+ * <pre>
+ *   // LAL:  parsed.level as String
+ *   // Generated:  h.toStr(h.group("level"))
+ * </pre>
+ *
+ * <p><b>3. Tag data</b> — accesses log tags (protobuf {@code KeyStringValuePair} list).
+ * Available regardless of parser type.
+ * <pre>
+ *   // LAL:  tag("LOG_KIND")
+ *   // Generated:  h.tagValue("LOG_KIND")
+ * </pre>
+ *
+ * <p><b>4. Log proto data</b> — direct access to {@code LogData.Builder} fields.
+ * Not accessed through this helper; the compiler generates direct getter chains
+ * like {@code h.ctx().log().getService()}.
+ *
+ * <p><b>5. ExtraLog proto data</b> — direct access to typed protobuf extraLog.
+ * Not accessed through this helper; the compiler generates typed cast + getter
+ * chains like {@code ((HTTPAccessLogEntry) h.ctx().extraLog()).getResponse()}.
+ *
+ * <h2>Type Conversion Methods</h2>
+ *
+ * <p>Convert parsed values (typically {@code Object}) to typed values for
+ * spec method calls.
+ * <pre>
+ *   // LAL:  parsed.service as String    →  h.toStr(h.mapVal("service"))
+ *   // LAL:  parsed.latency as Long      →  Long.valueOf(h.toLong(h.mapVal("latency")))
+ *   // LAL:  parsed.ssl as Boolean       →  Boolean.valueOf(h.toBool(h.mapVal("ssl")))
+ *   // LAL:  parsed.code as Integer      →  Integer.valueOf(h.toInt(h.mapVal("code")))
+ * </pre>
+ *
+ * <h2>Safe Navigation Methods</h2>
+ * <pre>
+ *   // LAL:  parsed?.x?.toString()       →  h.toString(h.mapVal("x"))
+ *   // LAL:  parsed?.x?.trim()           →  h.trim(h.mapVal("x"))
+ * </pre>
+ *
+ * <h2>Boolean Evaluation Methods</h2>
+ * <pre>
+ *   // LAL if-condition:  if (parsed.flag)        →  h.isTrue(h.mapVal("flag"))
+ *   // LAL if-condition:  if (parsed.name)        →  h.isNotEmpty(h.mapVal("name"))
+ * </pre>

+# MAL Compiler
+
+Compiles MAL (Meter Analysis Language) expressions into `MalExpression` implementation classes at runtime using ANTLR4 parsing and Javassist bytecode generation.
+
+## Compilation Workflow
+
+```
+MAL expression string
+  → MALScriptParser.parse(expression)          [ANTLR4 lexer/parser → visitor]
+  → MALExpressionModel.Expr (immutable AST)
+  → MALClassGenerator.compileFromModel(name, ast)
+      1. collectClosures(ast)          — pre-scan for closure arguments
+      2. addClosureMethod()            — add closure body as method on main class
+      3. classPool.makeClass()         — create main class implementing MalExpression
+      4. generateRunMethod()           — emit Java source for run(Map<String,SampleFamily>)
+      5. ctClass.toClass(MalExpressionPackageHolder.class)  — load via package anchor
+      6. wire closure fields via LambdaMetafactory (no extra .class files)
+  → MalExpression instance
+```
+
+The generated class implements `MalExpression`:
+```java
+SampleFamily run(Map<String, SampleFamily> samples)  // pure computation, no side effects
+ExpressionMetadata metadata()                         // compile-time metadata from AST
+```
+

+
+## Package & Class Naming
+
+All v2 classes live under `org.apache.skywalking.oap.meter.analyzer.v2.*` to avoid FQCN conflicts with the v1 (Groovy) classes.
+
+| Component | Package / Name |
+|-----------|---------------|
+| Parser/Model/Generator | `org.apache.skywalking.oap.meter.analyzer.v2.compiler` |
+| Generated classes | `org.apache.skywalking.oap.meter.analyzer.v2.compiler.rt.MalExpr_<N>` |
+| Package holder | `org.apache.skywalking.oap.meter.analyzer.v2.compiler.rt.MalExpressionPackageHolder` |
+| Runtime helper | `org.apache.skywalking.oap.meter.analyzer.v2.compiler.rt.MalRuntimeHelper` |
+| Functional interface | `org.apache.skywalking.oap.meter.analyzer.v2.dsl.MalExpression` |
+
+`<N>` is a global `AtomicInteger` counter.
+
+## Javassist Constraints
+
+- **No anonymous inner classes**: Javassist cannot compile `new Consumer() { ... }` or `new Function() { ... }` in method bodies.
+- **No lambda expressions**: Javassist has no lambda support.
+- **Closure approach**: Closure bodies are compiled as methods on the main class (e.g., `_tag_apply(Map)`), then wrapped via `LambdaMetafactory` into functional interface instances. No extra `.class` files are produced — the JVM creates hidden classes internally (same mechanism `javac` uses for lambdas).
+- **Inner class notation**: Use `$` not `.` for nested classes (e.g., `SampleFamilyFunctions$TagFunction`).
+- **`isPresent()`/`get()` instead of `ifPresent()`**: `ifPresent(Consumer)` would require an anonymous class. Use `Optional.isPresent()` + `Optional.get()` pattern.
+- **Closure interface dispatch**: Different closure call sites use different functional interfaces:
+  - `tag({ ... })` → `SampleFamilyFunctions$TagFunction`
+  - `forEach(closure)` / `serviceRelation(closure)` etc. → `SampleFamilyFunctions$ForEachFunction`
+  - `instance(closure)` → `SampleFamilyFunctions$PropertiesExtractor`
+  - `decorate(closure)` → `SampleFamilyFunctions$DecorateFunction`
+- **v2 package isolation**: All v2 classes are under `*.v2.*` packages, so there are no FQCN conflicts with the v1 Groovy module.
+
+## Example
+
+**Input**: `instance_jvm_cpu.sum(['service', 'instance'])`
+
+**Generated `run()` method** (pure computation, no ThreadLocal):
+```java
+public SampleFamily run(Map samples) {
+  return ((SampleFamily) samples.getOrDefault("instance_jvm_cpu", SampleFamily.EMPTY))
+      .sum(java.util.List.of("service", "instance"));
+}
+```
+
+**Generated `metadata()` method** (returns compile-time facts extracted from AST):
+```java
+public ExpressionMetadata metadata() {
+  // samples=["instance_jvm_cpu"], aggregationLabels=["service","instance"], ...
+  return new ExpressionMetadata(...);
+}
+```
+
+**Input with closure**: `metric.tag({ tags -> tags['k'] = 'v' })`
+
+One class is generated (`MalExpr_0`):
+- Method `_tag_apply(Map tags)` — contains `tags.put("k", "v"); return tags;`
+- Field `_tag` — typed as `TagFunction`, wired via `LambdaMetafactory` after class loading
+- `run()` body calls `metric.tag(this._tag)`
+
+## ExpressionMetadata (replaces ExpressionParsingContext)
+
+Metadata is extracted statically from the AST at compile time by `MALClassGenerator.extractMetadata()`. No ThreadLocal, no dry-run execution. The `Analyzer` calls `expression.metadata()` to get sample names, scope type, aggregation labels, downsampling, histogram/percentile info.
+
+## Debug Output
+
+When `SW_DYNAMIC_CLASS_ENGINE_DEBUG=true` environment variable is set, generated `.class` files are written to disk for inspection:
+
+```
+{skywalking}/mal-rt/
+  *.class          - Generated MalExpression .class files (one per expression, no separate closure classes)
+```
+
+This is the same env variable used by OAL. Useful for debugging code generation issues or comparing V1 vs V2 output. In tests, use `setClassOutputDir(dir)` instead.
+
+## MAL Input Data Mock Principles
+
+MAL test data lives in `.data.yaml` companion files alongside rule YAML files under `test/script-cases/scripts/mal/`. Each `.data.yaml` has two sections: `input` (mock samples) and `expected` (v1-verified output assertions).
+
+### Input Section Principles
+
+1. **Every metric referenced in rule expressions must have samples** — missing metrics produce EMPTY results (hard test failure).
+2. **Label variants for filters**: If a rule uses `tagEqual('cpu', 'cpu-total')`, the input must have samples with `cpu: cpu-total`. If another rule in the same file uses `tagNotEqual('cpu', 'cpu-total')`, there must also be samples with a different `cpu` value (e.g., `cpu: cpu0`).
+3. **`host` label for `service(['host'])`**: Rules with `expSuffix: service(['host'], ...)` derive the service entity name from the `host` label. All input samples should include a `host` label so the entity service name is non-empty.
+4. **Numeric YAML keys**: Some configs (e.g., zabbix `agent.yaml`) use numeric label keys like `1`, `2`. YAML parsers read these as `Integer`, not `String`. Test code must use `String.valueOf()` on both keys and values when building label maps.
+5. **Auto-generation**: `MalInputDataGenerator` extracts metric names and label requirements from compiled expression metadata. Run `MalInputDataGeneratorTest` to generate `.data.yaml` files for new rules. It skips files that already exist — delete the `.data.yaml` to regenerate.
+
+### Expected Section Principles
+
+1. **v1 is the truth**: The expected data is auto-generated by running the v1 (Groovy) engine on the input data. v1 is production-verified, so its output is the ground truth.
+2. **Non-empty output required**: If v1 produces EMPTY, the input data has a bug. Fix the input, not skip the test.
+3. **Rich assertions**: Expected includes entities (scope, service, instance, endpoint, layer) and samples (labels, value). Not just `min_samples: 1`.
+4. **Error markers**: `error: 'v1 not-success'` means v1 failed to execute the expression. Fix the input data so v1 succeeds.
+5. **Re-generation**: Run `MalExpectedDataGeneratorTest` to update expected sections after input data changes.
+
+### Directory Structure
+
+| Directory | Source |
+|-----------|--------|
+| `test-meter-analyzer-config` | `oap-server/server-starter/.../meter-analyzer-config/` |
+| `test-otel-rules` | `oap-server/server-starter/.../otel-rules/` |
+| `test-envoy-metrics-rules` | `oap-server/server-starter/.../envoy-metrics-rules/` |
+| `test-log-mal-rules` | `oap-server/server-starter/.../log-mal-rules/` |
+| `test-telegraf-rules` | `oap-server/server-starter/.../telegraf-rules/` |
+| `test-zabbix-rules` | `oap-server/server-starter/.../zabbix-rules/` |
+
+### YAML Key Variants
+
+| Key | Used by |
+|-----|---------|
+| `metricsRules` | Standard rule YAMLs (OTEL, meter-analyzer, envoy, log-mal, telegraf) |
+| `metrics` | Zabbix `agent.yaml` (production ZabbixConfig maps `metrics` to `getMetricsRules()`) |
+
+## Dependencies

-REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on
-why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial
-experiments, perform baseline and negative tests that provide experimental control, make sure
-the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts.
-Do not assume the numbers tell you what you want them to tell.

+# MAL/LAL/Hierarchy v1-v2 Comparison Checker
+
+Cross-version comparison tests that validate v2 (ANTLR4+Javassist) DSL compilers produce identical results to v1 (Groovy) compilers.
+
+## Test Classes
+
+| Class | Tests | Description |
+|-------|-------|-------------|
+| `MalComparisonTest` | ~1268 | Compiles and executes all MAL rules from 6 script directories |
+| `LalComparisonTest` | 35 | Compiles and executes all LAL rules from script directories |
+| `MalFilterComparisonTest` | 31 | Validates MAL filter operations (tagEqual, tagNotEqual, etc.) |
+| `MalInputDataGeneratorTest` | 1 | Generates `.data.yaml` companion files for MAL rules |
+| `MalExpectedDataGeneratorTest` | 1 | Generates expected sections in `.data.yaml` from v1 output |
+
+## How It Works
+
+For each DSL expression:
+1. Compile with v1 (Groovy) and v2 (ANTLR4+Javassist)
+2. Compare compile-time metadata (sample names, scope type, aggregation labels, etc.)
+3. Execute both with identical mock input data
+4. Assert output samples match (entities, labels, values)
+5. Validate against expected data in `.data.yaml` / `.input.data`
+
+## Script Directories (MAL)
+
+All under `test/script-cases/scripts/mal/`:
+
+| Directory | Source | Rules |
+|-----------|--------|-------|
+| `test-meter-analyzer-config` | `server-starter/.../meter-analyzer-config/` | ~17 configs |
+| `test-otel-rules` | `server-starter/.../otel-rules/` | ~73 service configs |
+| `test-envoy-metrics-rules` | `server-starter/.../envoy-metrics-rules/` | 3 configs |
+| `test-log-mal-rules` | `server-starter/.../log-mal-rules/` | 2 configs |
+| `test-telegraf-rules` | `server-starter/.../telegraf-rules/` | 1 config (vm.yaml) |
+| `test-zabbix-rules` | `server-starter/.../zabbix-rules/` | 1 config (agent.yaml) |
+
+## Input Data Mock Principles
+
+### MAL (.data.yaml files)
+
+Each MAL rule YAML has a companion `.data.yaml` with `input` and `expected` sections.
+
+**Input section:**
+- Every metric referenced in expressions must have samples
+- Label variants must cover all filter operations (tagEqual, tagNotEqual, tagMatch)
+- Labels from entity function `['label']` args (e.g., `instance(['host_name'], ['service_instance_id'])`) must be present in ALL input samples — these determine scope/service/instance/endpoint entity extraction
+- Numeric YAML keys (e.g., zabbix `1`, `2`) → use `String.valueOf()` in Java code
+
+**Expected section:**
+- Auto-generated from v1 (Groovy) execution output — v1 is the trusted baseline
+- Rich assertions: entities (scope/service/instance/endpoint/layer), samples (labels/value)
+- `error: 'v1 not-success'` means input data is broken — fix input, don't skip
+- EMPTY results are hard failures
+
+**YAML key variants:**
+- Standard rules use `metricsRules` key
+- Zabbix rules use `metrics` key (both are handled by the collector)
+
+### LAL (.input.data files)
+
+Each LAL rule YAML has a companion `.input.data` with per-rule test entries.
+
+**Entry structure:** service, body-type, body, optional tags/extra-log, expect assertions.
+
+**Expect assertions:** save, abort, service, instance, endpoint, layer, tag.*, sampledTrace.*
+
+**Proto-typed rules:** Use `extra-log.proto-class` + `extra-log.proto-json` for protobuf extraLog.
+
+### Hierarchy
+
+No data files — Service mock objects are built inline in test code.
+
+## Generators
+
+### MalInputDataGenerator
+
+Extracts metric names and label requirements from compiled AST metadata. Generates `.data.yaml` input sections automatically. Run via `MalInputDataGeneratorTest` — skips files that already exist.
+
+**Label sources extracted:**
+- Compiled metadata: `aggregationLabels` and `scopeLabels` from `ExpressionMetadata`
+- Tag filters: `tagEqual`, `tagNotEqual`, `tagMatch`, `tagNotMatch` arguments
+- Closure access: `tags.label` and `tags['label']` property/bracket access
+- Entity function arguments: `['label']` in `service()`, `instance()`, `endpoint()`, `process()` calls from `expSuffix`
+
+**Entity function labels** are critical — `instance(['host_name'], ['service_instance_id'], Layer.MYSQL)` requires `service_instance_id` in every input sample. Without it, the entity extraction produces incorrect scope/service/instance values. The generator parses `expSuffix` to find these `['label']` arguments automatically.
+
+### MalExpectedDataGenerator
+
+Runs v1 engine on input data and captures output as expected baseline. Run via `MalExpectedDataGeneratorTest` — updates the `expected:` section in existing `.data.yaml` files.
+
+## Adding New Rules
+
+1. Copy the production YAML to the appropriate `test-*` directory
+2. Run `MalInputDataGeneratorTest` to generate the `.data.yaml`
+3. Review input data — add missing label variants for filters
+4. Run `MalExpectedDataGeneratorTest` to generate expected sections
+5. Run `MalComparisonTest` to verify all tests pass
+6. Check for `error: 'v1 not-success'` in expected — fix input data
+
+## Duplicate Rule Names
+
+Some production configs (e.g., apisix.yaml) have duplicate rule names for route-based vs node-based variants. The collector disambiguates with `_2` suffix (e.g., `endpoint_http_status` → `endpoint_http_status_2`).
+
+## K8s Mocking
+
+Rules using `retagByK8sMeta` require K8s registry mocks. Both v1 and v2 K8sInfoRegistry are mocked via `Mockito.mockStatic()` in `@BeforeAll`. Mock `findServiceName(ns, pod)` returns `pod.ns`.
