# Phase 2 Remediation Progress Report

**Report Date**: 2026-02-02
**Report Time**: 17:50 UTC
**Status**: AWAITING AGENT LAUNCH

---

## Executive Summary

**Phase 2 remediation agents have not yet been started.** This report establishes the baseline and readiness for launching 5 parallel remediation agents to address 3,642 linting violations across the codebase.

### Baseline Snapshot (Pre-Remediation)

| Language | P0 Violations | P1 Violations | P2 Violations | Total |
|----------|--------------|--------------|--------------|-------|
| **Go** | 703 | 1,476 | 1,463 | 3,642 |
| **Python** | 0 | 0 | 0 | 0 |
| **Frontend** | 0 | 0 | 0 | 0 |
| **TOTAL** | **703** | **1,476** | **1,463** | **3,642** |

### Key Findings

1. **Python & Frontend Clean**: Both Python and Frontend codebases are currently passing all linters (Phase 1 hardening was effective)
2. **Go-Focused Effort**: All 3,642 violations are in the Go backend
3. **Priority Distribution**:
   - 19% P0 (critical correctness/security)
   - 41% P1 (complexity/maintainability)
   - 40% P2 (style/minor)

## Detailed Baseline by Language

### Go Backend (3,642 violations)

#### P0 Critical Violations (703 total)

| Linter | Count | Category | Impact |
|--------|-------|----------|---------|
| `errcheck` | 497 | Error handling | Unchecked errors can cause silent failures |
| `staticcheck` | 40 | Code correctness | Potential bugs and inefficiencies |
| `gosec` | 65 | Security | Security vulnerabilities (SQL injection, weak crypto, etc.) |
| `dupl` | 63 | Code duplication | Maintenance burden, bug propagation |
| `unused` | 21 | Dead code | Bloat, confusion |
| `ineffassign` | 17 | Dead assignments | Wasted computation, likely bugs |

**P0 Remediation Priority**:
1. `errcheck` (497) - Most critical for reliability
2. `gosec` (65) - Security vulnerabilities
3. `dupl` (63) - Extract shared functions
4. `staticcheck` (40) - Correctness fixes
5. `unused` (21) + `ineffassign` (17) - Cleanup

#### P1 Complexity Violations (1,476 total)

| Linter | Count | Category | Impact |
|--------|-------|----------|---------|
| `revive` | 1,205 | Style/naming/complexity | Code quality, readability |
| `funlen` | 203 | Function length | Hard to test, understand |
| `gocritic` | 39 | Code improvements | Performance, clarity |
| `gocognit` | 29 | Cognitive complexity | Hard to reason about |

**P1 Remediation Strategy**:
1. `revive` (1,205) - Many are auto-fixable (comments, naming)
2. `funlen` (203) - Requires refactoring (extract functions)
3. `gocognit` (29) - Most complex, requires careful redesign

#### P2 Style/Minor Violations (1,463 total)

| Linter | Count | Category | Remediation |
|--------|-------|----------|-------------|
| `mnd` | 719 | Magic numbers | Extract constants |
| `perfsprint` | 565 | Performance | Use faster sprintf alternatives |
| `goconst` | 60 | Repeated strings | Extract constants |
| `whitespace` | 32 | Formatting | Auto-fix |
| `nolintlint` | 23 | Lint directives | Improve nolint comments |
| `prealloc` | 18 | Slice allocation | Pre-allocate slices |
| `gochecknoglobals` | 17 | Global variables | Refactor to dependency injection |
| `noctx` | 15 | Missing context | Add context.Context parameters |
| `exhaustive` | 9 | Enum switches | Add missing cases |
| `unconvert` | 5 | Unnecessary conversions | Remove |

**P2 Remediation**: Many are auto-fixable or low-effort. Defer to Phase 3.

## Phase 2 Execution Timeline (Revised)

### Pre-Launch (Current)
- [x] Establish baseline (3,642 violations)
- [x] Identify scope (Go backend only)
- [x] Create agent assignment plan

### Phase 2A: Go P0 Remediation (40-60 hours)
- [ ] Launch Agent 1: Error Handling (parallel)
- [ ] Launch Agent 2: Security & Duplication (parallel)
- [ ] Launch Agent 3: Dead Code Cleanup (parallel)
- [ ] Monitor progress (this report updates every 8 hours)
- [ ] Validate tests pass after each agent
- [ ] Merge remediation branches

### Phase 2B: Baseline Validation
- [ ] Re-run `make lint`
- [ ] Confirm P0 violations = 0
- [ ] Document remaining P1/P2 for Phase 3

## Blockers & Risks

### Current Blockers
1. **No agents launched**: Waiting for authorization to start 3 Go remediation agents
2. **Missing test baseline**: Need to run `make test` to establish test pass rate
3. **Missing build verification**: Need to verify `make build` succeeds

### Risk Assessment
| Risk | Probability | Impact | Mitigation |
|------|-------------|--------|------------|
| Test failures during remediation | HIGH | HIGH | Run tests after each fix batch |
| Breaking changes in refactoring | MEDIUM | HIGH | Small commits, incremental validation |
| Excessive time on edge cases | MEDIUM | MEDIUM | Time-box to 60 hours, defer hard cases to Phase 3 |
| Merge conflicts between agents | LOW | MEDIUM | Agents work on different files/linters |

---

## Next Steps (Immediate Actions Required)

### 1. Pre-Flight Checks (5 minutes)
```bash
# Verify build passes
make build

# Run test suite and capture baseline
make test > /tmp/test_baseline.log 2>&1

# Verify dev stack starts
make dev-tui  # Check services start cleanly
```

### 2. Launch Parallel Agents (5 minutes)
- Start Agent 1: Go Error Handling
- Start Agent 2: Go Security & Duplication
- Start Agent 3: Go Dead Code Cleanup
- Document agent start times and PIDs

### 3. Monitoring Setup (5 minutes)
- Set up 8-hour check-in schedule
- Create agent progress tracking sheet
- Configure alerts for test failures

### 4. First Progress Check (8 hours from launch)
- Collect interim results from all 3 agents
- Update this report with progress %
- Identify blockers or delays
- Adjust time estimates if needed
