# 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.**

## Safety / Boundary Checks

### Prohibited Operations (Verified Absent)

| Operation | Status | Verification Method |
|---|---|---|
| subprocess calls from Streamlit | ✅ None | Source code grep |
| CLI invocation from Streamlit | ✅ None | Source code grep |
| Direct runner calls from Streamlit | ✅ None | Source code grep |
| External LLM/API calls from Streamlit | ✅ None | Source code grep |
| Eval-v2 auto-execution from UI | ✅ None | Architecture design |
| Background job execution | ✅ None | Architecture design |
| Artifact mutation (trace.json, prediction.csv) | ✅ None | Architecture design |
| Unsafe file upload execution | ✅ None | Code review |

### Execution Boundaries

| Boundary | Status | Location |
|---|---|---|
| CLI delegates to services | ✅ Enforced | `src/data_agent_baseline/cli.py` |
| 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](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.
