# repo-seed
# markitect-quarkdown
A git repository template to bootstrap coulomb projects from.
`markitect-quarkdown` provides the concrete Quarkdown render/export adapter for
Markitect. It keeps Quarkdown runtime assumptions out of `markitect-tool` while
still satisfying the Markitect render adapter contract.
## Scope
This repository owns:
- `render.quarkdown` adapter descriptor and entry point
- Markitect profile to Quarkdown profile mapping
- controlled Quarkdown CLI execution plans
- Quarkdown permission and runtime dependency mapping
- generated artifact validation and checksums
- open-reuse integration metadata
It does not reimplement Quarkdown, fork Quarkdown, or make core Markitect
responsible for renderer behavior.
## Development
Run tests from this checkout:
```bash
PYTHONPATH=src:/home/worsch/markitect-tool/src python3 -m pytest
```
The suite uses fake execution for adapter-boundary tests. A real Quarkdown
runtime smoke check skips when `quarkdown` is not installed.
## Entry Point
```toml
[project.entry-points."markitect_tool.render_export_adapters"]
quarkdown = "markitect_quarkdown.adapter:quarkdown_adapter_descriptor"
```
## Docs
- `docs/adapter-boundary.md`
- `docs/profile-matrix.md`
- `docs/permissions-and-runtime.md`

# Markitect Quarkdown Adapter Boundary
`markitect-quarkdown` provides the concrete `render.quarkdown` adapter for the
Markitect render/export contract. Core `markitect-tool` owns the passive
request/result/artifact/provenance contracts; this repository owns Quarkdown
runtime behavior.
## Adapter Contract
The adapter supports:
- `inspect-profile`
- `export-source`
- `render-artifact`
`inspect-profile` and `export-source` do not invoke Quarkdown. `render-artifact`
requires a Quarkdown CLI plus runtime dependencies.
The adapter descriptor declares filesystem writes, external process execution,
native renderer dependency, and permission-controlled network behavior. Callers
can block render execution through Markitect request policy:
```python
RenderExportRequest(
source="# Demo",
operation="render-artifact",
profile="pdf",
policy={"external_process": False},
)
```
## Execution Plan
`build_quarkdown_execution_plan` produces an inspectable command plan with:
- Quarkdown command path
- source file path
- output directory
- expected artifact path
- Markitect profile
- Quarkdown document type
- output format
- permission flags
- runtime dependency notes
The default output directory is `quarkdown-output`. The default permission
allow-list is `project-read`, and network access is denied by default.
## Structured Failure
The adapter returns `RenderExportResult` diagnostics instead of raising for
expected render failures:
- `render.quarkdown.runtime_missing`
- `render.quarkdown.execution_failed`
- `render.quarkdown.artifact_missing`
- `render.quarkdown.artifact_extension`
- `render.quarkdown.artifact_empty`
- `render.quarkdown.capability_blocked`
## Artifact Validation
`validate_quarkdown_artifact` validates that the expected artifact exists, has
the expected extension, is non-empty, and receives a sha256 digest. The result
is a Markitect `RenderArtifact` with source-to-artifact provenance generated by
the adapter.

# Permissions And Runtime
Quarkdown 2.x introduced compile-time permissions. The Markitect adapter treats
those as renderer-local execution controls, not as enterprise authorization.
## Permission Mapping
The adapter recognizes Quarkdown permission names as CLI flags:
- `project-read`
- `global-read`
- `network`
- `native-content`
- `all`
The default allow-list is:
```text
project-read
```
The adapter denies `network` by default unless callers explicitly opt out with
`deny_network: false`.
## Runtime Dependencies
The descriptor declares these optional runtime assumptions:
- Quarkdown 2.x CLI
- Java 17+
- Node.js, npm, and Puppeteer for PDF export
The test suite does not require those tools. It uses a fake runner for command
boundary tests and skips the real-runtime smoke check when `quarkdown` is not
available on `PATH`.
## Output Conventions
The default output directory is `quarkdown-output`. Expected artifact names are
derived from `artifact_stem` plus the profile extension, for example
`demo.pdf` for `profile=pdf`.
This repository owns those conventions and compatibility monitoring. Core
`markitect-tool` only sees `RenderExportResult`, `RenderArtifact`, diagnostics,
and provenance.

# Quarkdown Profile Matrix
The adapter maps Markitect render profiles onto Quarkdown document/output
intent. The CLI command is still configurable because Quarkdown distribution
and command spelling may change across 2.x releases.
| Markitect profile | Quarkdown document type | Output format | Artifact media type | Extension |
| --- | --- | --- | --- | --- |
| `plain` | `plain` | `txt` | `text/plain` | `.txt` |
| `docs` | `docs` | `html` | `text/html` | `.html` |
| `slides` | `slides` | `html` | `text/html` | `.html` |
| `paged` | `paged` | `pdf` | `application/pdf` | `.pdf` |
| `static-site` | `docs` | `html` | `text/html` | `.html` |
| `pdf` | `paged` | `pdf` | `application/pdf` | `.pdf` |
PDF-oriented profiles require Quarkdown's PDF runtime path, including Java and
Node.js/npm/Puppeteer assumptions.
## Options
The adapter accepts these stable Markitect-facing options:
- `command`: Quarkdown command name or path, default `quarkdown`
- `workspace`: temporary working directory override
- `output_dir`: output directory, default `quarkdown-output`
- `artifact_stem`: expected artifact basename, default from source stem
- `permissions`: Quarkdown permission allow-list, default `project-read`
- `deny_network`: append a network deny flag, default `true`
- `dry_run`: return an execution-plan artifact without invoking Quarkdown
Renderer packages and automation may add extra options, but they should remain
under this adapter boundary rather than leaking into `markitect-tool`.

## Implementation Summary
Completed as the initial native Quarkdown render adapter boundary:
- Added a Python package with a `render.quarkdown` descriptor registered under
`markitect_tool.render_export_adapters`.
- Implemented `MarkitectQuarkdownAdapter` for `inspect-profile`,
`export-source`, and controlled `render-artifact` execution.
- Added Markitect profile to Quarkdown document/output mapping, option schema,
permission mapping, default output conventions, dry-run plan artifacts, and
structured runtime/execution/artifact diagnostics.
- Added artifact validation with extension, non-empty, digest, media type, and
source-to-artifact provenance.
- Added docs, an example render request, open-reuse integration metadata, and
tests that use fake execution plus a real-runtime skip hook.
