Ingest OpenERA Enterprise AI Framework evidence manifest

[ProfessorPolymorphic]

What

Add an ingestion path for OpenERAs machine-readable Enterprise AI Framework evidence manifest.

Manifest contract:

• Raw manifest: https://raw.githubusercontent.com/ui-insight/OpenERA/main/docs/governance/enterprise-ai-framework/evidence.json
• Schema: https://raw.githubusercontent.com/ui-insight/OpenERA/main/docs/governance/enterprise-ai-framework/evidence.schema.json
• OpenERA parent tracker: https://github.com/ui-insight/OpenERA/issues/797
• OpenERA evidence-label filter: https://github.com/ui-insight/OpenERA/issues?q=is%3Aissue%20label%3Astandards-evidence

Why

OpenERA is starting to document project compliance with OITs Enterprise AI Development Framework. AISPEG should be able to aggregate compliance assertions and evidence status without scraping Markdown or GitHub issue prose.

Acceptance criteria

• Fetch and validate the OpenERA evidence.json payload against evidence.schema.json.
• Store or render requirements keyed by project.slug + framework.id + requirements[].id.
• Show both compliance assertion status (current_assertion.status) and work-tracking status from linked GitHub issues.
• Refresh linked GitHub issue state by issue number.
• Surface evidence sources and blockers for each requirement.
• Handle future projects by adding more manifest URLs rather than hardcoding OpenERA-only logic.

Suggested implementation notes

AISPEG already has lib/standards-watch.ts and GitHub issue tooling in lib/github.ts. This should become a project-compliance evidence feed that complements, not replaces, the institutional standards ledger.
