**Status**: RECONCILIATION DOCUMENT
**Date**: 2026-03-01
**Author**: CTO + PM
**Purpose**: Clarify sprint numbering, hours, and roadmap alignment

## Current State Confusion - RESOLVED

### What roadmap.md says:
```
Sprint 63 ← CURRENT (37h)
Sprint 64-65 ← Context Anchoring
Sprint 66-67 ← Zoekt (20h, conditional)
Sprint 68 ← Compliance (40h)
Sprint 72 ← Autonomy (80h)
Total: 217h
```

### What CEO says:
```
"Chúng ta đang ở Sprint 65 rồi nhé"
```

### What MEMORY.md says:
```
Sprint 61-62 Complete ✅
Sprint 63-64 Complete ✅ (Code Search Foundation)
Sprint 65+ Adjustments (Research-Driven)
```

### RESOLVED: Actual Current State
```
Sprint 61-62: ✅ COMPLETE (Init + Compliance)
Sprint 63-64: ✅ COMPLETE (Code Search Foundation - RgProvider, AstGrepProvider stub, basic logging)
Sprint 65: 🔄 IN PROGRESS - Context Anchoring (Week 2 of 3 complete)
  ├── Week 1: SESSION-PROGRESS.md ✅
  ├── Week 2: Spec Snapshot (ADR-011) ✅
  └── Week 3: Git Time-Travel + Checkpoints ⏳
```

## Hours Reconciliation

### Original Master Plan v4.2 (Total REMAINING work from Sprint 63+)

| Sprint | Focus | Hours | Status |
|--------|-------|-------|--------|
| 63-64 | Code Search Foundation | 37h | ✅ COMPLETE |
| 65 | Context Anchoring | 40h | 🔄 IN PROGRESS (~20h remaining) |
| 66-67 | Zoekt Scale-Up | 20h | ⏳ PENDING (conditional) |
| 68 | Compliance | 40h | ⏳ PENDING |
| 72 | Autonomy | 80h | ⏳ PENDING |
| **TOTAL** | | **217h** | **~37h done, 180h remaining** |

### Revised Plan v4.3 (Post-Research, from Sprint 65 current position)

| Sprint | Focus | Hours | Status |
|--------|-------|-------|--------|
| 65 | Context Anchoring | 20h | 🔄 IN PROGRESS (2/3 complete) |
| 66 | Retrieval Intelligence | 40h | ⏳ NEW (from research) |
| 67 | Zoekt Scale-Up | 20h | ⏳ CONDITIONAL |
| 68 | Compliance | 40h | ⏳ SAME |
| 69-71 | Session Resilience | 30h | ⏳ NEW (from research) |
| 72 | Autonomy + AER | 40h | ⏳ REVISED |
| **TOTAL REMAINING** | | **190h** | **From current position** |

### What Changed?

**Completed** (no longer in scope):
- ✅ Sprint 63-64: 37h (DONE)
- ✅ Sprint 65 Week 1-2: ~20h (DONE)

**Added**:
- ➕ Sprint 66: Retrieval Intelligence 40h (dual-output logger, spec boost, stage/role boost)
- ➕ Sprint 69-71: Session Resilience 30h (checkpointing, failure classification, recovery)

**Reduced**:
- ➖ Sprint 72: 80h → 40h (scope optimization, focus on core autonomy)

**Net change**: 217h total → 190h remaining (+70h new work, -97h scope optimization/completion)

## Detailed Breakdown: What's in Each Sprint?

### Sprint 65: Context Anchoring (40h total, ~20h remaining)

**Week 1 ✅ DONE (10h)**:
- SESSION-PROGRESS.md generation
- Event-based anchoring triggers

**Week 2 ✅ DONE (10h)**:
- Spec Snapshot implementation (ADR-011)
- Drift detection

**Week 3 ⏳ REMAINING (20h)**:
- Git Time-Travel (branch context injection)
- Checkpoint create/restore
- Sprint Goals persistence
- **NEW**: Dual-output logger foundation (from research)
- **NEW**: RankingReason enum implementation (from research)

### Sprint 66: Retrieval Intelligence (40h) - NEW

**What it is**: Complete the Code Search Layer with explainability and context-awareness.

**Why it's NEW**: Research report identified gaps in Sprint 63-64:
- Sprint 63-64 had **basic** retrieval logging → SESSION-PROGRESS.md only
- Sprint 66 adds **intelligence**: machine-readable logs, spec/stage/role boosting, explainability

**Breakdown**:
- Dual-output logger (human + machine): 10h
- Spec snapshot boosting: 8h
- Stage/role-aware retrieval: 10h
- AstGrepProvider full implementation: 12h (conditional on benchmark)

**Deliverables**:
- `retrieval-log.jsonl` (machine-readable)
- Spec/stage/role boost in retrieval-policy.ts
- Benchmark Scenario #5 validation
- Full AstGrepProvider (if benchmark passes)

### Sprint 67: Zoekt Scale-Up (20h) - CONDITIONAL (unchanged)

Same as original plan. Only execute if BFlow benchmark shows P95 > 2s.

### Sprint 68: Compliance (40h) - SAME

Same as original plan:
- Stage Contracts
- PatchManager
- Risk Scoring
- Decision Packets

### Sprint 69-71: Session Resilience (30h) - NEW

**What it is**: Autonomous session manager with recovery and checkpointing.

**Why it's NEW**: Research report emphasized failure recovery as critical for v2.0 autonomy:
- Without recovery: Agent fails → session lost → CEO starts over
- With recovery: Agent fails → classify → retry or rollback → continue

**Breakdown**:
- Session state machine: 10h
- Checkpoint system: 10h
- Failure classification (TRANSIENT/FIXABLE/DESIGN_ISSUE): 10h

**Deliverables**:
- SessionManager with state machine
- Auto-checkpoint every 5 patches
- Failure classification engine
- Auto-recovery for TRANSIENT/FIXABLE

**Justification**: This is CRITICAL for v2.0. Original plan assumed autonomy without addressing recovery. Research showed recovery is 30% of autonomy work.

### Sprint 72: Autonomy + AER Metrics (40h) - REVISED

**Original** (80h):
- 2h autopilot sessions
- Full SDLC loop
- Minimal interventions
- (No metrics, no tiering, no observability)

**Revised** (40h):
- Enhanced AER metrics (TCR, RR, Tool Choice, Cost): 10h
- Model Tiering with Opus cap: 10h
- Autonomous Session Manager: 12h
- Golden scenarios validation: 8h

**Why reduced 80h → 40h?**
- Original 80h was inflated (included discovery, R&D)
- Session Resilience (Sprint 69-71) now handles checkpointing/recovery
- Retrieval Intelligence (Sprint 66) now handles context management
- Sprint 72 focuses on orchestration only

## Justification for Changes

### Why add Sprint 66 (Retrieval Intelligence)?

**Gap identified**: Sprint 63-64 implemented **basic** code search:
- ✅ RgProvider works
- ✅ AstGrepProvider stub exists
- ✅ Logs to SESSION-PROGRESS.md

**What's missing** (from research):
- ❌ No machine-readable logs → can't calculate AER metrics
- ❌ No explainability → can't debug ranking
- ❌ No spec/stage/role context → low relevance for SDLC stages
- ❌ No benchmark for ast-grep → don't know if worth implementing

**Sprint 66 fills the gap**: 40h to complete what Sprint 63-64 started.

### Why add Sprint 69-71 (Session Resilience)?

**Gap identified**: Original plan had no recovery mechanism:
- v1.8 (Sprint 68): Compliance guards (prevent errors)
- v2.0 (Sprint 72): Autonomy (run 120min+)
- ❌ **Missing**: What happens when errors occur during 120min session?

**Research insight**: Autonomous agents MUST have:
1. Failure classification (TRANSIENT vs FIXABLE vs DESIGN_ISSUE)
2. Auto-retry for TRANSIENT (network, rate limit)
3. Fix loop for FIXABLE (lint, test failures)
4. Escalation for DESIGN_ISSUE (spec mismatch)
5. Checkpointing every N patches

**Sprint 69-71 fills the gap**: 30h for recovery infrastructure.

### Why reduce Sprint 72 (80h → 40h)?

**Original 80h included**:
- Checkpointing: 20h → Moved to Sprint 69-71
- Context management: 15h → Moved to Sprint 66
- Metrics/observability: 10h → Moved to Sprint 72 (kept)
- Session manager: 15h → Moved to Sprint 69-71
- Autonomy orchestration: 20h → Sprint 72 (kept)

**Revised 40h focuses on**:
- Enhanced AER metrics: 10h
- Model Tiering: 10h
- Autonomous orchestration: 12h
- Golden scenarios validation: 8h

**Rationale**: Break down monolithic 80h sprint into focused sprints (66, 69-71, 72).
