+# Dev Container Features Repo
+
+Template for authoring and publishing [Dev Container Features](https://containers.dev/implementors/features/) to GitHub Container Registry.
+
+## Repository Structure
+
+```
+src/<feature>/
+  devcontainer-feature.json   # Feature metadata, options, version
+  install.sh                  # Entrypoint, runs as root during build
+test/<feature>/
+  scenarios.json               # Test scenarios (optional)
+  test.sh                      # Auto-generated tests (runs against defaults)
+  <scenario_name>.sh           # Per-scenario test scripts
+test/_global/
+  scenarios.json               # Multi-feature integration tests
+```
+
+## Required CLI
+
+Install the devcontainer CLI globally:
+
+```bash
+npm install -g @devcontainers/cli
+```
+
+## Development Commands
+
+**Validate feature metadata:**
+```bash
+devcontainer features validate --base-path ./src
+```
+
+**Test a single feature (auto-generated):**
+```bash
+devcontainer features test -f <feature> --skip-scenarios -i mcr.microsoft.com/devcontainers/base:ubuntu .
+```
+
+**Test a single feature (scenarios only):**
+```bash
+devcontainer features test -f <feature> --skip-autogenerated .
+```
+
+**Test global scenarios:**
+```bash
+devcontainer features test --global-scenarios-only .
+```
+
+## Feature Implementation Notes
+
+- `install.sh` always runs as **root** during container build
+- Options from `devcontainer-feature.json` are passed as **capitalized env vars** (e.g., `favorite` → `FAVORITE`)
+- Use `$_REMOTE_USER` and `$_CONTAINER_USER` for user context if needed
+- Feature version is defined in `devcontainer-feature.json` (semver)
+- Declare dependencies via `installsAfter` in metadata
+
+## CI Workflows
+
+- `.github/workflows/validate.yml`: Validates `devcontainer-feature.json` on PR
+- `.github/workflows/test.yaml`: Runs auto-generated + scenario tests on PR/push
+- `.github/workflows/release.yaml`: Publishes to GHCR (manual trigger, main branch only)
+
+## Publishing
+
+- Namespace: `ghcr.io/<owner>/<repo>/<feature>:<version>`
+- Requires `package:write` permission and GITHUB_TOKEN
+- Packages default to **private** in GHCR; must manually set to **public** in package settings
+- README auto-generated per feature (merges `src/<feature>/NOTES.md` if exists)
+
+## Test Library
+
+Tests can use the bundled test library:
+
+```bash
+source dev-container-features-test-lib
+check "<label>" <command> [args...]
+reportResults
+```
+
+## Resources
+
+- [Feature spec](https://containers.dev/implementors/features/)
+- [Test docs](https://github.com/devcontainers/cli/blob/main/docs/features/test.md)
+- [Distribution spec](https://containers.dev/implementors/features-distribution/)

+# Development Context: Conan Feature
+
+**Last Updated:** 2026-04-16  
+**Status:** Feature implementation complete, ready for testing
+
+---
+
+## Current State
+
+The **conan** feature has been created and is ready for testing. All core functionality is implemented.
+
+### Files Created
+
+```
+src/conan/
+├── devcontainer-feature.json    # Feature metadata with conanVersion option
+└── install.sh                  # Multi-distro installation script
+
+test/conan/
+├── scenarios.json              # Test scenarios for all distros

+└── specific_version.sh         # Specific version test (conanVersion: 1.66)
+```
+
+---
+
+## Feature Details
+
+### Options
+
+- **`conanVersion`** (string, default: "latest")  
+  Version of Conan to install (e.g., "2.0.14", "1.60.2", or "latest")
+
+- **`userHome`** (string, default: "/home/$_REMOTE_USER")  
+  Home directory for the user (used for Conan cache)
+
+### Supported Distributions
+
+| Distro    | Test Scenario | Base Image         |
+|-----------|---------------|-------------------|
+| Ubuntu    | ubuntu        | ubuntu:latest     |
+| Debian    | debian        | debian:latest     |
+| Fedora    | fedora        | fedora:latest     |
+| Arch Linux| archlinux     | archlinux:latest  |
+
+---
+
+## Installation Method
+
+Conan is installed in a **global virtual environment** at `/opt/conan-venv`:
+
+1. Checks if Python3 is installed (installs if missing)
+2. Creates `/opt/conan-venv` virtual environment
+3. Installs Conan via pip in the venv
+4. Symlinks `/usr/local/bin/conan` → `/opt/conan-venv/bin/conan`
+5. Sets permissions for all users
+
+### Version Conflict Detection
+
+The script checks for existing Conan installation:
+
+- If `conanVersion: "latest"` → Accepts any installed version
+- If installed version matches requested → Skips installation
+- If versions mismatch → **ERROR** with conflict details
+
+Example error:
+```
+ERROR: Version conflict detected!
+  Requested version: 2.0.0
+  Installed version: 1.66.0
+Please remove the existing Conan installation or use 'latest' to accept any version.
+```
+
+---
+
+## Testing Commands
+
+### Validate metadata
+```bash
+devcontainer features validate --base-path ./src
+```
+
+### Run auto-generated test (Ubuntu with defaults)
+```bash
+devcontainer features test -f conan --skip-scenarios -i ubuntu:latest .
+```
+
+### Run all scenario tests
+```bash
+devcontainer features test -f conan --skip-autogenerated .
+```
+
+### Run specific scenario
+```bash
+# Test on Fedora
+devcontainer features test -f conan -i fedora:latest .
+
+# Test specific version scenario (conanVersion: 1.66)
+devcontainer features test -f conan --filter specific_version --skip-autogenerated .
+```
+
+### Run everything (auto-generated + scenarios)
+```bash
+devcontainer features test -f conan .
+```
+
+---
+
+## Scenarios Configuration
+
+```json
+{
+    "ubuntu": {
+        "image": "ubuntu:latest",
+        "features": { "conan": {} }
+    },
+    "debian": {
+        "image": "debian:latest",
+        "features": { "conan": {} }
+    },
+    "fedora": {
+        "image": "fedora:latest",
+        "features": { "conan": {} }
+    },
+    "archlinux": {
+        "image": "archlinux:latest",
+        "features": { "conan": {} }
+    },
+    "specific_version": {
+        "image": "ubuntu:latest",
+        "features": {
+            "conan": { "conanVersion": "1.66" }
+        }
+    }
+}
+```
+
+---
+
+## Example Usage in devcontainer.json
+
+```jsonc
+{
+    "image": "ubuntu:latest",
+    "features": {
+        "ghcr.io/<owner>/<repo>/conan:1": {
+            "conanVersion": "latest"
+        }
+    }
+}
+```
+
+With specific version:
+```jsonc
+{
+    "image": "ubuntu:latest",
+    "features": {
+        "ghcr.io/<owner>/<repo>/conan:1": {
+            "conanVersion": "2.0.0"
+        }
+    }
+}
+```
+
+---
+
+## Next Steps
+
+1. Run full scenario test suite to verify all distros work
+2. Check CI workflows (if CI is enabled for this repo)
+3. Publish feature to GHCR when ready:
+   ```bash
+   # Via GitHub Actions workflow_dispatch on .github/workflows/release.yaml
+   # Or manually:
+   devcontainer features publish ./src
+   ```

+# Session Cache - Conan Feature Update
+
+## Project
+Dev Container Features repo at `/root/projs/devcontainer-features`
+
+## Task
+Modify `conan` feature to only support Conan 1.x (user plans preconfiguration options incompatible with Conan 2)
+
+## Changes Made
+
+### src/conan/devcontainer-feature.json
+- Name: "Conan Package Manager (1.x)"
+- Version bumped to 1.1.0
+- Kept `conanVersion` option but restricted to 1.x only
+- Documentation URL: https://docs.conan.io/en/1.x/
+
+### src/conan/install.sh
+- Refactored into clean functions: `validate_version()`, `check_existing_conan()`, `detect_distribution()`, `install_python()`, `install_conan()`, `setup_conan_home()`
+- Validates requested version is 1.x (rejects 2.x)
+- "latest" installs `conan<2` (newest 1.x)
+- Uses `.conan` directory (Conan 1.x format) not `.conan2`
+
+### test/conan/
+- `scenarios.json`: kept `specific_version` with `"conanVersion": "1.66.0"`
+- `specific_version.sh`: checks for 1.66.0
+- `test.sh`: checks for 1.x version format
+
+## Key Decisions
+- Keep version parameter, restrict to 1.x (not remove it)
+- Write test values hardcoded per standard devcontainer feature practice
+
+## Files Modified
+- src/conan/devcontainer-feature.json
+- src/conan/install.sh
+- test/conan/scenarios.json
+- test/conan/specific_version.sh

-# Development Context: Conan Feature
-
-**Last Updated:** 2026-04-16  
-**Status:** Feature implementation complete, ready for testing
-
----
-
-## Current State
-
-The **conan** feature has been created and is ready for testing. All core functionality is implemented.
-
-### Files Created
-
-```
-src/conan/
-├── devcontainer-feature.json    # Feature metadata with conanVersion option
-└── install.sh                  # Multi-distro installation script

-└── specific_version.sh         # Specific version test (conanVersion: 1.66)
-```
-
----
-
-## Feature Details
-
-### Options
-
-- **`conanVersion`** (string, default: "latest")  
-  Version of Conan to install (e.g., "2.0.14", "1.60.2", or "latest")
-
-- **`userHome`** (string, default: "/home/$_REMOTE_USER")  
-  Home directory for the user (used for Conan cache)
-
-### Supported Distributions
-
-| Distro    | Test Scenario | Base Image         |
-|-----------|---------------|-------------------|
-| Ubuntu    | ubuntu        | ubuntu:latest     |
-| Debian    | debian        | debian:latest     |
-| Fedora    | fedora        | fedora:latest     |
-| Arch Linux| archlinux     | archlinux:latest  |
-
----
-
-## Installation Method
-
-Conan is installed in a **global virtual environment** at `/opt/conan-venv`:
-
-1. Checks if Python3 is installed (installs if missing)
-2. Creates `/opt/conan-venv` virtual environment
-3. Installs Conan via pip in the venv
-4. Symlinks `/usr/local/bin/conan` → `/opt/conan-venv/bin/conan`
-5. Sets permissions for all users
-
-### Version Conflict Detection
-
-The script checks for existing Conan installation:
-
-- If `conanVersion: "latest"` → Accepts any installed version
-- If installed version matches requested → Skips installation
-- If versions mismatch → **ERROR** with conflict details
-
-Example error:
-```
-ERROR: Version conflict detected!
-  Requested version: 2.0.0
-  Installed version: 1.66.0
-Please remove the existing Conan installation or use 'latest' to accept any version.
-```
-
----
-
-## Testing Commands
-
-### Validate metadata
-```bash
-devcontainer features validate --base-path ./src
-```
-
-### Run auto-generated test (Ubuntu with defaults)
-```bash
-devcontainer features test -f conan --skip-scenarios -i ubuntu:latest .
-```
-
-### Run all scenario tests
-```bash
-devcontainer features test -f conan --skip-autogenerated .
-```
-
-### Run specific scenario
-```bash
-# Test on Fedora
-devcontainer features test -f conan -i fedora:latest .
-
-# Test specific version scenario (conanVersion: 1.66)
-devcontainer features test -f conan --filter specific_version --skip-autogenerated .
-```
-
-### Run everything (auto-generated + scenarios)
-```bash
-devcontainer features test -f conan .
-```
-
----
-
-## Scenarios Configuration
-
-```json
-{
-    "ubuntu": {
-        "image": "ubuntu:latest",
-        "features": { "conan": {} }
-    },
-    "debian": {
-        "image": "debian:latest",
-        "features": { "conan": {} }
-    },
-    "fedora": {
-        "image": "fedora:latest",
-        "features": { "conan": {} }
-    },
-    "archlinux": {
-        "image": "archlinux:latest",
-        "features": { "conan": {} }
-    },
-    "specific_version": {
-        "image": "ubuntu:latest",
-        "features": {
-            "conan": { "conanVersion": "1.66" }
-        }
-    }
-}
-```
-
----
-
-## Example Usage in devcontainer.json
-
-```jsonc
-{
-    "image": "ubuntu:latest",
-    "features": {
-        "ghcr.io/<owner>/<repo>/conan:1": {
-            "conanVersion": "latest"
-        }
-    }
-}
-```
-
-With specific version:
-```jsonc
-{
-    "image": "ubuntu:latest",
-    "features": {
-        "ghcr.io/<owner>/<repo>/conan:1": {
-            "conanVersion": "2.0.0"
-        }
-    }
-}
-```
-
----
-
-## Next Steps
-
-1. Run full scenario test suite to verify all distros work
-2. Check CI workflows (if CI is enabled for this repo)
-3. Publish feature to GHCR when ready:
-   ```bash
-   # Via GitHub Actions workflow_dispatch on .github/workflows/release.yaml
-   # Or manually:
-   devcontainer features publish ./src
-   ```

-# Session Cache - Conan Feature Update
-
-## Project
-Dev Container Features repo at `/root/projs/devcontainer-features`
-
-## Task
-Modify `conan` feature to only support Conan 1.x (user plans preconfiguration options incompatible with Conan 2)
-
-## Changes Made
-
-### src/conan/devcontainer-feature.json
-- Name: "Conan Package Manager (1.x)"
-- Version bumped to 1.1.0
-- Kept `conanVersion` option but restricted to 1.x only
-- Documentation URL: https://docs.conan.io/en/1.x/
-
-### src/conan/install.sh
-- Refactored into clean functions: `validate_version()`, `check_existing_conan()`, `detect_distribution()`, `install_python()`, `install_conan()`, `setup_conan_home()`
-- Validates requested version is 1.x (rejects 2.x)
-- "latest" installs `conan<2` (newest 1.x)
-- Uses `.conan` directory (Conan 1.x format) not `.conan2`
-
-### test/conan/
-- `scenarios.json`: kept `specific_version` with `"conanVersion": "1.66.0"`
-- `specific_version.sh`: checks for 1.66.0
-- `test.sh`: checks for 1.x version format
-
-## Key Decisions
-- Keep version parameter, restrict to 1.x (not remove it)
-- Write test values hardcoded per standard devcontainer feature practice
-
-## Files Modified
-- src/conan/devcontainer-feature.json
-- src/conan/install.sh
-- test/conan/scenarios.json
-- test/conan/specific_version.sh
-- test/conan/test.sh
