Phase 14 Release Audit — DAO Data Agent Observatory
Date: 2026-06-24
Branch: feature/observatory-phase-14-dao-branding-release-audit
Purpose: Final release readiness audit and branding standardization
Release Scope
Phase 14 completes the stable demo-ready release by:
- Standardizing product branding as DAO — Data Agent Observatory
- Conducting comprehensive release readiness audit
- Validating Phase 0–13 capabilities remain intact
- Documenting known limitations and deferred blueprint items
- Providing a clean checkpoint before deeper execution/evaluation changes
No execution, evaluation, or artifact-behavior changes.

trace.json never modified after task completion
- ✅
prediction.csv never modified after task completion
- ✅
run_manifest.json only updated during execution
- ✅
run_events.jsonl only appended, never truncated
- ✅ Eval-v2 artifacts only created/regenerated, never mutated
- ✅ All Phase 8–13 artifacts are additive only

Known Limitations
Execution Model
- ❌ No true pause/resume of in-flight tasks
- ❌ No background job execution infrastructure
- ❌ No multi-user execution queue
- ❌ No cancellation of running tasks
- ❌ Execution remains synchronous within Streamlit session
Evaluation Model
- ❌ No eval-v2 auto-run from Streamlit
- ❌ Custom tasks without gold data cannot be scored for correctness
- ❌ No automatic paired autonomous/guided comparison runs
- ❌ No causal inference for steering effects
Checkpoint and Steering
- ❌ No in-execution intervention (checkpoints are post-hoc review only)
- ❌ No automatic prompt rewriting from steering instructions
- ❌ Guided reruns execute as new isolated runs (no true state resume)
Statistical Analysis
- ❌ No automatic significance testing (Evidence Pack requires manual review)
- ❌ No causal claims supported (observational associations only)
- ❌ Sample size thresholds for significance testing documented but not enforced
Artifact Migration
- ❌ No canonical
evaluation/ subfolder migration (eval-v2 artifacts remain at run root)
- ❌ No Parquet conversion for large CSV outputs
Advanced Features
- ❌ No optional external LLM-backed Q&A (rules-based intent matching only)
- ❌ No cross-run statistical studies
- ❌ No automatic ablation experiment generation
Deferred Blueprint Completion Items
The original KDD_Data_Agent_Observatory_Phased_Architecture_Blueprint.md defined 21 phases. The stable release completes Phases 0–14.

| Phase 16 |

Blueprint Phases 17–21 (Deferred to Roadmap)

Reason for deferral: Phases 15–16 are planned immediate post-release hardening. Phases 17–21 require deeper runtime or evaluation changes and should be attempted only after release stabilization.
