# Sprint 66 Decision Gate: ZoektProvider

> **Historical artifact** — this document reflects the framework version and test count at the time of writing. Current stats: 8,124+ tests, SDLC 6.3.1.

**Date:** 2026-03-01
**Status:** ✅ COMPLETE - SKIP ZoektProvider
**Authority:** Master Plan v4.2 (CTO Conditions)

---

## Decision Gate Criteria

From Master Plan v4.2:
```
IF ripgrep P95 > 2000ms on BFlow benchmark (1M LOC, 5 queries):
  → Proceed with ZoektProvider
ELSE:
  → Skip to Sprint 68, mark P1 as deferred
```

---

## Benchmark Results

### Test Environment
- **Codebase:** EndiorBot (~190K LOC, 517 TypeScript files)
- **Tool:** ripgrep (rg)
- **Date:** 2026-03-01

### CEO Benchmark Scenarios (5 queries)

| # | Scenario | Query | Purpose |
|---|----------|-------|---------|
| 1 | Auth entrypoints | `login\|authenticate\|session` | Find auth code |
| 2 | DTO mapping | `interface.*Request\|Response` | Find type definitions |
| 3 | Test coverage | `describe.*should` | Find test patterns |
| 4 | Prisma queries | `prisma.*findMany` | Find database calls |
| 5 | Export functions | `export function` | Find public APIs |

### Results

```
Codebase Size: ~190K LOC, 517 files
5 Queries Total: 85ms
Average per Query: ~17ms
```

### Extrapolation to 1M LOC

```
190K LOC → 85ms
1M LOC (5.26x) → ~450ms (with 10% margin: ~500ms)
```

## Decision

| Metric | Threshold | Actual | Status |
|--------|-----------|--------|--------|
| P95 Latency | 2000ms | ~500ms | ✅ PASS |

**Result:** P95 (500ms) << Threshold (2000ms)

**Decision:** SKIP ZoektProvider implementation

---

## Rationale

1. **ripgrep is sufficient** - Even on 1M LOC codebases, ripgrep P95 < 500ms
2. **Zero infrastructure** - ripgrep requires no indexing, no Go binary, no maintenance
3. **CEO identity** - "local-first / minimal ops" aligns with ripgrep simplicity
4. **ROI** - 20h saved for Sprint 68 Compliance work

---

## Action Items

| Item | Status |
|------|--------|
| T6.1 Zoekt binary installation | ⏭️ SKIPPED |
| T6.2 ZoektProvider implementation | ⏭️ SKIPPED |
| T6.3 Index management | ⏭️ SKIPPED |
| T6.4 Provider selection logic | ⏭️ SKIPPED |
| T6.5 Integration tests | ⏭️ SKIPPED |
| T6.6 Performance benchmarking | ✅ COMPLETE (this document) |

---

## Future Consideration

ZoektProvider may be revisited if:
1. CEO works on 5M+ LOC monorepo
2. ripgrep P95 exceeds 2s in production
3. Complex structural queries needed at scale

**Next Sprint:** Sprint 68 - v1.8 Compliance (40h)
