+description: Add namespaced custom fields to Feature and ProjectBundle without modifying core models.
+---
+
+# Extending ProjectBundle
+
+Modules can extend `Feature` and `ProjectBundle` with custom metadata using the **schema extension system** (arch-07). Extensions use namespace-prefixed keys so multiple modules can store data without conflicts.
+
+## Overview
+
+- **`extensions`** – A dict on `Feature` and `ProjectBundle` that stores module-specific data under keys like `backlog.ado_work_item_id` or `sync.last_sync_timestamp`.
+- **`get_extension(module_name, field, default=None)`** – Read a value.
+- **`set_extension(module_name, field, value)`** – Write a value.
+- **`schema_extensions`** – Optional declaration in `module-package.yaml` so the CLI can validate and introspect which fields a module uses.
+
+## Using Extensions in Code
+
+```python
+from specfact_cli.models.plan import Feature
+from specfact_cli.models.project import ProjectBundle
+
+# On a Feature (e.g. from a bundle)
+feature.set_extension("backlog", "ado_work_item_id", "123456")
+value = feature.get_extension("backlog", "ado_work_item_id") # "123456"
+missing = feature.get_extension("backlog", "missing", default="default") # "default"
+
+# On a ProjectBundle
+bundle.set_extension("sync", "last_sync_timestamp", "2025-01-15T12:00:00Z")
+ts = bundle.get_extension("sync", "last_sync_timestamp")
+```
+
+**Rules:**
+
+- `module_name`: lowercase, alphanumeric plus underscores/hyphens, **no dots** (e.g. `backlog`, `sync`).
+- `field`: lowercase, alphanumeric plus underscores (e.g. `ado_work_item_id`).
+- Keys are stored as `module_name.field` (e.g. `backlog.ado_work_item_id`).
+
+## Declaring Extensions in the Manifest
+
+In `module-package.yaml` you can declare which extensions your module uses so the CLI can detect collisions and support introspection:
+
+```yaml
+name: backlog
+version: "0.1.0"
+commands: [backlog]
+
+schema_extensions:
+ - target: Feature
+ field: ado_work_item_id
+ type_hint: str
+ description: Azure DevOps work item ID for sync
+ - target: Feature
+ field: jira_issue_key
+ type_hint: str
+ description: Jira issue key when using Jira adapter
+ - target: ProjectBundle
+ field: last_sync_timestamp
+ type_hint: str
+ description: ISO timestamp of last sync
+```
+
+- **target** – `Feature` or `ProjectBundle`.
+- **field** – Snake_case field name (must match `[a-z][a-z0-9_]*`).
+- **type_hint** – Documentation only (e.g. `str`, `int`).
+- **description** – Human-readable description.
+
+If two modules declare the same `(target, field)` (e.g. both declare `Feature.ado_work_item_id`), the second module’s schema extensions are skipped and an error is logged.
+
+## Best Practices
+
+- Use a single logical namespace per module (the module name).
+- Prefer short, clear field names (`ado_work_item_id`, `last_sync_timestamp`).
+- Document extensions in `schema_extensions` so other tools and docs can introspect them.
+- Do not rely on extension values for core behavior; keep them as optional metadata.
+
+## Backward Compatibility
+
+- Existing bundles and features without an `extensions` field load with `extensions = {}`.
+- Modules that omit `schema_extensions` load and run normally; no extensions are registered for them.

+description: How to use arch-06 (module security) and arch-07 (schema extensions) from CLI commands and as a module author.
+nav_order: 22
+---
+
+# Using Module Security and Schema Extensions
+
+With **arch-06** (manifest security) and **arch-07** (schema extension system) in place, you can use verified modules and store module-specific metadata on bundles and features. This guide shows how to utilize these features from the CLI and in your own modules.
+
+## Quick reference
+
+| Capability | What it does | Where to read more |
+|------------|--------------|--------------------|
+| **arch-06** | Publisher + integrity (checksum/signature) on module manifests; versioned dependencies | [Module Security](/reference/module-security/) |
+| **arch-07** | `extensions` dict on Feature/ProjectBundle; `get_extension`/`set_extension`; `schema_extensions` in manifest | [Extending ProjectBundle](/guides/extending-projectbundle/) |
+
+---
+
+## Using arch-06 (module security)
+
+### As a CLI user (consuming modules)
+
+- **Verified modules**: When you run any command that loads modules (e.g. `specfact backlog ...`, `specfact project ...`), the registry discovers modules and, when a module has `integrity.checksum` in its `module-package.yaml`, verifies the manifest checksum before registering. If verification fails, that module is skipped and a warning is logged; other modules still load.
+- **Unsigned modules**: Modules without `integrity` metadata are allowed by default (backward compatible). To document explicit opt-in in strict environments, set:
+ ```bash
+ export SPECFACT_ALLOW_UNSIGNED=1
+ ```
+- **Versioned dependencies**: Manifests can declare `module_dependencies_versioned` and `pip_dependencies_versioned` (each entry: `name`, `version_specifier`) for install-time resolution. You don’t need to do anything special; the installer uses these when present.
+
+You don’t run a separate “verify” command; verification happens automatically at module registration when the CLI starts.
+
+### As a module author (publishing a module)
+
+1. **Add publisher and integrity to `module-package.yaml`** (optional but recommended):
+
+ ```yaml
+ name: my-module
+ version: "0.1.0"
+ commands: [my-group]
+
+ publisher:
+ name: "Your Name or Org"
+ email: "contact@example.com"
+
+ integrity:
+ checksum: "sha256:" # Required for verification
+ signature: "" # Optional; requires trusted key on consumer side
+ ```
+
+2. **Generate the checksum** using the bundled script:
+
+ ```bash
+ ./scripts/sign-module.sh path/to/module-package.yaml
+ # Output: sha256:
+ # Add that value to integrity.checksum in the manifest
+ ```
+
+3. **CI**: Use `.github/workflows/sign-modules.yml` (or equivalent) to produce or validate checksums when manifest files change.
+
+4. **Versioned dependencies** (optional):
+
+ ```yaml
+ module_dependencies_versioned:
+ - name: backlog-core
+ version_specifier: ">=0.2.0"
+ pip_dependencies_versioned:
+ - name: requests
+ version_specifier: ">=2.28.0"
+ ```
+
+Details: [Module Security](/reference/module-security/).
+
+---
+
+## Using arch-07 (schema extensions)
+
+### As a CLI user (running commands that use extensions)
+
+Several commands already read or write extension data on `ProjectBundle` (and its manifest). You use them as usual; extensions are persisted with the bundle.
+
+- **Link a backlog provider** (writes `backlog_core.backlog_config` on project metadata):
+ ```bash
+ specfact project link-backlog --bundle my-bundle --adapter github --project-id my-org/my-repo
+ ```
+- **Health check and other project commands** read that same extension to resolve adapter/project/template:
+ ```bash
+ specfact project health-check --bundle my-bundle
+ ```
+
+Any command that loads a bundle (e.g. `specfact plan ...`, `specfact sync ...`, `specfact spec ...`) loads the full bundle including `extensions`; round-trip save keeps extension data. So you don’t need a special “extensions” command to benefit from them—they’re part of the bundle.
+
+**Introspecting registered extensions (programmatic):** There is no `specfact extensions list` CLI yet. From Python you can call:
+
+```python
+from specfact_cli.registry.extension_registry import get_extension_registry
+all_exts = get_extension_registry().list_all() # dict: module_name -> list of SchemaExtension
+```
+
+### As a module author (using extensions in your commands)
+
+1. **Declare extensions** in `module-package.yaml` so the CLI can validate and avoid collisions:
+
+ ```yaml
+ schema_extensions:
+ - target: Feature
+ field: my_custom_id
+ type_hint: str
+ description: My module’s external ID for this feature
+ - target: ProjectBundle
+ field: last_sync_ts
+ type_hint: str
+ description: ISO timestamp of last sync
+ ```
+
+2. **In your command code**, when you have a `ProjectBundle` or `Feature` (e.g. from `load_bundle_with_progress` or from a plan bundle):
+
+ ```python
+ from specfact_cli.models.plan import Feature
+ from specfact_cli.models.project import ProjectBundle
+
+ # On a Feature
+ feature.set_extension("my_module", "my_custom_id", "EXT-123")
+ value = feature.get_extension("my_module", "my_custom_id") # "EXT-123"
+ missing = feature.get_extension("my_module", "other", default="n/a") # "n/a"
+
+ # On ProjectBundle (e.g. bundle.manifest.project_metadata or bundle itself)
+ bundle.set_extension("my_module", "last_sync_ts", "2026-02-16T12:00:00Z")
+ ts = bundle.get_extension("my_module", "last_sync_ts")
+ ```
+
+3. **Naming rules**: `module_name`: lowercase, alphanumeric + underscores/hyphens, **no dots**. `field`: lowercase, alphanumeric + underscores. Keys are stored as `module_name.field` (e.g. `my_module.my_custom_id`).
+
+4. **Project metadata**: The built-in `project link-backlog` command uses **project_metadata** (on the bundle manifest), which also supports `get_extension`/`set_extension` with the same `module_name.field` convention (e.g. `backlog_core.backlog_config`). Use the same pattern for your module’s config stored on the project.
+

+
+## Summary
+
+- **arch-06**: Use `scripts/sign-module.sh` and `integrity`/`publisher` in manifests; consumers get automatic checksum verification at registration; set `SPECFACT_ALLOW_UNSIGNED=1` if you explicitly allow unsigned modules.
+- **arch-07**: Use `get_extension`/`set_extension` on Feature and ProjectBundle in your module code; declare `schema_extensions` in `module-package.yaml`; use existing commands like `specfact project link-backlog` and `specfact project health-check` to see extensions in action.

+## Schema Extension System
+
+`arch-07-schema-extension-system` lets modules extend `Feature` and `ProjectBundle` with namespaced custom fields without changing core models.
+
+- **Extensions field**: `Feature` and `ProjectBundle` have an `extensions: dict[str, Any]` field (default empty dict). Keys use the form `module_name.field` (e.g. `backlog.ado_work_item_id`).
+- **Accessors**: `get_extension(module_name, field, default=None)` and `set_extension(module_name, field, value)` enforce namespace format and type safety via contracts.
+- **Manifest**: Optional `schema_extensions` in `module-package.yaml` declare target model, field name, type hint, and description. Lifecycle loads these and registers them in a global extension registry.
+- **Collision detection**: If two modules declare the same (target, field), the second registration is rejected and an error is logged; module command registration continues.
+- See [Extending ProjectBundle](/guides/extending-projectbundle/) for usage and best practices.

Ensure the script writes logs under `logs/tests/` (existing behavior of smart_test_coverage.py when level is full).
-- [ ] 3.3 Add a step to upload test log artifacts: use `actions/upload-artifact@v4` with name `test-logs` (or `test-logs-py312`), path `logs/tests/`, and `if-no-files-found: ignore` or `warn` so the job does not fail if no logs (e.g. when step was skipped). Use `if: always()` or `if: success() || failure()` so artifacts are uploaded on both success and failure when the step ran.
-- [ ] 3.4 Keep or adjust the existing "Upload coverage artifacts" step so quality-gates still receives coverage (e.g. continue uploading `logs/tests/coverage/coverage.xml` as `coverage-reports` if that path is still produced by smart-test-full or a separate coverage step).
