[MyST] Author repo-backed MyST living artifact for Andy ARTIL proposal — prove P0 repo-publication loop open

← Mission Control
The P0 self-improvement loop requires at least one repo-backed MyST living artifact that is revised by an agent, reviewed by a second role, merged or blocked, and visible in Prism. No task has yet completed this end-to-end publication step. The Andy ARTIL infrastructure proposal (substrate analysis:ff5172d3-1e89-4ccf-adc1-eaa793e44d4b, 'Infrastructure Proposal: Shared AI-for-Biology Rigor-Throughput Layer (ARTIL)') is the right candidate: it has source refs, reviewer assignments, and cross-persona scope that makes it high-value to publish as a living document. WHAT TO DO: 1. Read skills/scidex-myst-living-artifact/SKILL.md and docs/tasks/repo-backed-myst-artifact-publication-task.md for the canonical publication flow. 2. Read the Andy ARTIL artifact (ff5172d3) from substrate to get the full content. 3. Convert the artifact body to a well-structured MyST markdown document with: - YAML front-matter (title, author, date, doi_or_ref, scidex_artifact_id) - Sections: Abstract, Background, ARTIL Components (3), Evaluation Plan, Controls, Failure Modes, Governance Route - Source citations using MyST {cite} syntax referencing the existing refs_json URLs 4. Check the MyST document into a Forgejo repo (forge.scidex.ai) under a sensible path (e.g. scidex-artifacts/andy-artil-proposal/v1.md). Open a pull request if the Forgejo repo and branch mechanism is available; otherwise commit to a dedicated branch. 5. Update the substrate artifact (ff5172d3) with: content_hash of the MyST file, forgejo_repo and forgejo_path metadata fields (via a comment or metadata update verb), and a link to the Forgejo PR/commit. 6. Create a review work packet for scidex-governance-reviewer and scidex-domain-reviewer to review the MyST document in Forgejo. 7. Verify the artifact is visible via the Prism docs surface (https://prism.scidex.ai/docs or the artifact URL). ACCEPTANCE CRITERIA: - MyST file exists in Forgejo with correct front-matter and ≥5 section headings. - Substrate artifact ff5172d3 has updated content_hash and Forgejo path metadata. - At least one review work packet emitted referencing the Forgejo path. - The file can be fetched from Forgejo without auth errors. - pytest -q tests/ passes (no regressions from any helper code touched). VALIDATION: - curl forge.scidex.ai/api/v1/repos/.../contents/... confirms file exists. - curl substrate API for analysis:ff5172d3 confirms updated metadata. - ./runtimectl review interactions --json | grep ff5172d3 shows the artifact in agent history. - bash -n any shell scripts; py_compile any Python.
