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:

  1. Standardizing product branding as DAO — Data Agent Observatory
  2. Conducting comprehensive release readiness audit
  3. Validating Phase 0–13 capabilities remain intact
  4. Documenting known limitations and deferred blueprint items
  5. Providing a clean checkpoint before deeper execution/evaluation changes

No execution, evaluation, or artifact-behavior changes.

  • 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

Streamlit delegates to services ✅ Enforced src/data_agent_baseline/observatory/*_page.py
Services own orchestration ✅ Enforced src/data_agent_baseline/application/
Repositories own persistence ✅ Enforced src/data_agent_baseline/repositories/
Builders are pure functions ✅ Enforced src/data_agent_baseline/observatory/*_builders.py

Data Safety

Safety Check Status
Uploaded files sanitized ✅ Path traversal protection
File size limits enforced ✅ 50MB default limit
File checksums computed ✅ SHA256 hashing
Unsupported file types rejected ✅ Validation layer
No arbitrary code execution ✅ Static files 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.

Blueprint Phases 15–16 (Post-Release Planned)

Phase Capability Priority Risk
Phase 15 Run + Evaluation Workflow (eval-v2 trigger from Streamlit) Medium Medium
Phase 16 Live DAG/Replay during execution Medium High

Blueprint Phases 17–21 (Deferred to Roadmap)

Phase Capability Priority Risk
Phase 17 Canonical evaluation folder migration Low Low
Phase 18 Optional LLM-backed Q&A Low Medium
Phase 19 True pause/resume execution Low High
Phase 20 Cross-run statistical studies Low Medium
Phase 21 Automatic ablation experiments Low High

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.
