## 1. World State Analysis

### Current State (2026-02-12)

| Dimension | State | Details |
|-----------|-------|---------|
| **Version** | v0.1.14 | Phase 3 complete, released |
| **Build** | ✅ Passing | Syntax error in core.rs fixed (duplicated code block removed) |
| **Clippy** | ✅ 0 warnings | Strict `-D warnings` enforced |
| **Tests** | ✅ Passing | 811+ lib tests |
| **Coverage CI** | ✅ Fixed | Disk space fix deployed (commit 85a6f76) |
| **Dependabot** | ✅ Resolved | All 6 PRs resolved via main branch updates |
| **Stale Workflows** | ✅ Removed | ci-old.yml not present (already cleaned) |
| **MCP Lazy Loading** | ✅ Implemented | `list_all_tools()`, `get_all_extended_tools()` implemented |
| **Plans Cleanup** | ✅ Complete | ~80K lines of stale docs removed (~214 files changed) |
| **Token Optimization** | 🟡 Partial | Lazy tool loading done, field selection pending |
| **Error Handling** | ⚠️ 143 unwraps | Need conversion to proper error handling |
| **Embeddings** | 🟡 85% complete | Remaining 15% integration pending |
| **Codebase** | ~198K LOC | 791 Rust files, 147+ test files |

### Blockers - PHASE 1 RESOLVED ✅
1. **~~CI Coverage~~**: ✅ Fixed - Disk space fix deployed (jlumbroso/free-disk-space@v2)
2. **~~Dependabot~~**: ✅ Resolved - All 6 PRs consolidated via main branch updates
3. **~~Stale Workflow~~**: ✅ Removed - ci-old.yml already cleaned from repository

### Current Blockers - PHASE 2 (MCP Token Optimization)
1. **MCP Field Selection**: Not yet implemented (20-60% token savings potential)
2. **Adaptive TTL Phase 2.3**: Implementation pending
3. **MCP Lazy Loading Docs**: ADR-024 documentation needed

---

## 2. Goal State (v0.1.15 Targets)

| Goal | Measurable Outcome |
|------|-------------------|
| **CI Fully Green** | All GitHub Actions workflows passing, coverage badge restored |
| **Dependencies Current** | All 5 Dependabot PRs merged or closed with rationale |
| **Clean Workflows** | ci-old.yml removed, no stale workflow files |
| **MCP Token Savings ≥50%** | Lazy loading + field selection combined savings |
| **Adaptive TTL** | Phase 2.3 adaptive TTL implemented and tested |
| **Error Handling Improved** | ≤50 unwraps remaining (from 143) |
| **Embeddings ≥95%** | Remaining integration completed |
| **Quality Gates** | >90% coverage, 0 clippy warnings, all tests pass |

---

## 3. Gap Analysis

| Gap | Current | Target | Effort | Priority |
|-----|---------|--------|--------|----------|
| CI coverage disk full | ❌ Broken | ✅ Passing | 1-2h | P0 |
| Dependabot PRs failing | 5 blocked | 0 blocked | 2-4h | P0 |
| Stale ci-old.yml | Present | Removed | 0.5h | P0 |
| MCP field selection | Not started | Implemented | 4-6h | P1 |
| Adaptive TTL Phase 2.3 | Pending | Complete | 6-8h | P1 |
| MCP lazy loading docs | Code done | Documented | 1-2h | P1 |
| Error handling (143 unwraps) | 143 | ≤50 | 8-12h | P2 |
| Embeddings integration (15%) | 85% | ≥95% | 6-10h | P2 |

**Total Estimated Effort**: 29-44 hours

## 4. Research Summary (2026-02-12)

### GitHub Actions Disk Space Management
**Finding**: Use `easimon/maximize-build-space@master` instead of `jlumbroso/free-disk-space@v2`
**Rationale**: LVM-based consolidation provides 7-8 GB guaranteed space gain
**Source**: perplexity-researcher-reasoning-pro (2026 best practices)

### Dependabot PR Analysis
**Finding**: All 6 PRs safe to merge; CI failures are pre-existing (7 do-memory-mcp tests)
**Risk Matrix**:
- sysinfo 0.38.1: 5/100 (LOW) - patch, macOS support restore
- reqwest 0.13.2: 5/100 (LOW) - patch, bug fixes
- criterion 0.8.2: 25/100 (MEDIUM) - major, dev-only, MSRV 1.86 (project: 1.93 ✅)
- GitHub Actions updates: 1/100 (MINIMAL) - standard patches
**Source**: rust-specialist analysis

### Multi-Agent Coordination Strategy
**Finding**: Group agents by independence; spawn 4-5 agents in parallel for P0 tasks
**Optimal Grouping**:
- Group 1 (CI/CD): github-workflows + build-compile + code-quality
- Group 2 (Dependencies): rust-specialist + clean-code-developer
- Group 3 (MCP): mcp-protocol + architecture-validator
- Group 4 (Quality): code-reviewer + testing-qa
**Source**: AGENTS.md coordination patterns

---

## 5. Action Plan

### Phase 1: CI Stabilization (P0) — Days 1-2 (STARTING NOW)

#### Task 1.1: Fix Coverage Workflow Disk Space
- **Action**: Add `easimon/maximize-build-space@master` action (2026 best practice)
- **File**: `.github/workflows/coverage.yml`
- **Rationale**: Runner disk fills during coverage instrumented build; easimon action provides 7-8 GB guaranteed space gain via LVM consolidation
- **Configuration**:
  ```yaml
  - name: Maximize build space
    uses: easimon/maximize-build-space@master
    with:
      root-reserve-mb: 512
      swap-size-mb: 1024
      remove-dotnet: 'true'
      remove-android: 'true'
      remove-haskell: 'true'
  ```
- **Acceptance**: Coverage workflow passes, Codecov badge restored
- **Effort**: 1-2 hours
- **Dependencies**: None
- **Research Source**: perplexity-researcher-reasoning-pro (2026-02-12)

#### Task 1.2: Add Disk Space Monitoring to Coverage Workflow
- **Action**: Add disk usage logging before/after cleanup
- **File**: `.github/workflows/coverage.yml`
- **Rationale**: Monitor disk space to catch future regressions
- **Configuration**:
  ```yaml
  - name: Log disk usage before
    run: |
      df -h /
      du -h -d1 / | sort -hr | head -n 20
  - name: Log disk usage after cleanup
    run: |
      df -h /
      du -h -d1 / | sort -hr | head -n 20
  ```
- **Acceptance**: Disk logs uploaded as artifacts for debugging
- **Effort**: 30 minutes
- **Dependencies**: None (parallel with 1.1)

#### Task 1.3: Merge Dependabot PRs (6 PRs, All Safe)
- **Action**: Merge all 6 Dependabot PRs in recommended order
- **PRs**:
  1. PR #272: actions/download-artifact v4.1.8 (GitHub Actions)
  2. PR #273: github/codeql-action v3.27.5 (GitHub Actions)
  3. PR #274: actions/upload-artifact v4.6.2 (GitHub Actions)
  4. PR #270: sysinfo 0.38.0 → 0.38.1 (patch, LOW risk)
  5. PR #269: reqwest 0.13.1 → 0.13.2 (patch, LOW risk)
  6. PR #271: criterion 0.5.1 → 0.8.2 (major dev-only, MEDIUM risk)
- **Rationale**: CI failures are pre-existing (7 do-memory-mcp tests), NOT from dependency updates
- **Pre-Merge Validation**: ✅ All PRs build and pass clippy locally
- **Expected Outcome**: 7 pre-existing test failures in do-memory-mcp (unrelated to deps)
- **Acceptance**: All 6 PRs merged, CI green for non-pre-existing failures
- **Effort**: 1-1.5 hours
- **Dependencies**: None (parallel with 1.1, 1.2)
- **Research Source**: rust-specialist analysis (2026-02-12)

#### Task 1.4: Remove Stale ci-old.yml
- **Action**: Delete `.github/workflows/ci-old.yml`
- **Rationale**: Dead workflow confuses CI status and reviewers
- **Acceptance**: File removed, no workflow references remain
- **Effort**: 0.5 hours
- **Dependencies**: None (parallel with 1.1, 1.2, 1.3)

### Phase 2: MCP Token Optimization (P1) — Days 3-7

#### Task 2.1: Document MCP Lazy Tool Loading (ADR-024)
- **Action**: Create ADR-024, update ADR index
- **Files**: `plans/adr/ADR-024-MCP-Lazy-Tool-Loading.md`, `plans/ARCHITECTURE/ARCHITECTURE_DECISION_RECORDS.md`
- **Acceptance**: ADR complete with implementation details
- **Effort**: 1-2 hours
- **Dependencies**: None

#### Task 2.2: MCP Field Selection/Projection
- **Action**: Implement `include_fields` parameter per ADR-021
- **Files**: `do-memory-mcp/src/tools/queries.rs`, `do-memory-mcp/src/tools/episodes.rs`, new `do-memory-mcp/src/utils/serialization.rs`
- **Rationale**: 20-60% additional token reduction on responses
- **Acceptance**: `include_fields` parameter works on query_memory, get_episode; tests pass
- **Effort**: 4-6 hours
- **Dependencies**: Task 1.1 (need CI green to validate)

#### Task 2.3: Adaptive TTL Implementation
- **Action**: Complete Phase 2.3 adaptive TTL for cache layer
- **Files**: `do-memory-storage-turso/src/cache/adaptive_ttl.rs` and related modules
- **Rationale**: Dynamic TTL adjustment based on access patterns
- **Acceptance**: Adaptive TTL tests pass, cache hit rate measurably improved
- **Effort**: 6-8 hours
- **Dependencies**: None (parallel with 2.2)

### Phase 3: Quality Improvements (P2) — Days 8-14

#### Task 3.1: Error Handling Audit
- **Action**: Convert 93+ unwraps to proper error handling (target: reduce from 143 to ≤50)
- **Files**: Across all workspace crates
- **Rationale**: Production robustness, prevent panics
- **Acceptance**: ≤50 unwraps remaining, all tests pass
- **Effort**: 8-12 hours
- **Dependencies**: Phase 1 complete (CI green)

#### Task 3.2: Complete Embeddings Integration
- **Action**: Complete remaining 15% of embeddings integration
- **Files**: `do-memory-core/src/embeddings/`, integration with pattern extraction
- **Rationale**: Full embedding-based pattern clustering (Phase 2 of ADR-002)
- **Acceptance**: Embedding-based clustering functional, ≥95% integration
- **Effort**: 6-10 hours
- **Dependencies**: Phase 1 complete
