State–Evidence production cutover for canonical presentation

[xueyang-dev]

Summary

This draft PR makes the State–Evidence Kernel and Canonical Presentation Blueprint the authoritative production upstream.

Production path

Source / learner analysis
→ LearningStatePlan
→ EvidencePlan
→ ActivityPlan
→ EvidenceAlignmentGate
→ PresentationContentPlan
→ PresentationMediaRequestPlan
→ AbstractPresentationBindings
→ CanonicalPresentationBlueprint
→ deterministic LegacyLessonBlueprint adapter
→ existing HTML/PPTX renderers
→ quality gates
→ export

What changed

• run_full_pipeline() and POST /api/projects/{project_id}/blueprint use the canonical blueprint-stage compiler.
• Legacy blueprints/lesson_blueprint.json is read-only compatibility output with mapping/provenance artifacts.
• Evidence alignment, canonical compilation, adapter mapping, readiness, and reconciliation blockers stop downstream generation without fallback.
• Renderer-facing routes require the complete canonical production contract and fingerprint consistency.
• Source/profile/State–Evidence upstream fingerprints invalidate canonical, legacy, media, render, quality, and delivery state.
• Non-deterministic LLM providers explicitly return llm_production_contract_unsupported; their complete-Slides contract remains diagnostic-only.
• The web UI removes legacy Blueprint editing and exposes Provider production-contract status.
• Documentation and an audit/progress record describe production, compatibility, diagnostic, and experimental boundaries.

Verification

• npm test: 652 passed, 3 skipped, 6 warnings
• npm run test:e2e: 14 passed
• npm run build:web: passed
• Frontend state contract: passed
• Python compileall and git diff --check: passed

Remaining migration work

• Migrate non-deterministic LLM Providers to source-grounded upstream analysis/evidence/activity suggestions.
• Extend canonical media request planning to source-grounded image requests where provenance exists.
• Run teacher-led production pilots and future classroom validation.
