## Part 2: Scenario-Based Contingencies

### Scenario 1: Design Phase Completion Failure

**Problem**: Design phase stalls before completing all 517 sites

**Root causes**:
- [ ] Design agent crashes or times out
- [ ] SDESIGN workflow has errors
- [ ] Resource exhaustion during design
- [ ] Input data corrupted

**Detection**:
- [ ] Design phase shows no progress for 30+ minutes
- [ ] Check: `ls .smbatcher/designs/*.md | wc -l` stuck on low number
- [ ] Error messages in design logs

**Response Plan** (Priority order):

1. **Diagnose** (5 min)
   ```bash
   # How many designs exist?
   DESIGNS=$(ls .smbatcher/designs/*-DESIGN.md 2>/dev/null | wc -l)

   # How many should exist?
   TOTAL=$(tools/shared/list-sites.sh --batch 001 | wc -l)

   echo "Generated: $DESIGNS / $TOTAL"

   # Check for errors
   if [ -f logs/design.log ]; then
     tail -50 logs/design.log | grep -i error
   fi
   ```

2. **Assess** (5 min)
   - [ ] If < 90% designed: Redeploy design phase (acceptable, just restarts)
   - [ ] If ~100% designed: Finalize what exists, document missing sites
   - [ ] If 50-90% designed: Check error patterns before redeploying

3. **Remediate** (depends on assessment)
   - **If redeployable**: `tools/prepare/mdesign.sh --batch 001`
   - **If partially complete**: Accept current designs, skip missing
   - **If systemic error**: Fix root cause, restart design phase

**Expected outcome**: Design phase completes with >= 90% sites (acceptable)

**Impact on schedule**: +1-2 hours if full redesign needed

---

### Scenario 2: Implementation Phase Stalls

**Problem**: I-status count stops increasing for 45+ minutes

**Root causes**:
- [ ] All agents completed work (check I-status = 517)
- [ ] Agents crashed or were terminated
- [ ] Registry system issue (status not updating)
- [ ] File generation extremely slow
- [ ] System resource exhaustion

**Detection**:
- [ ] Monitor observes I-status unchanged after 45 min
- [ ] Check: O-status still > 0 (work remaining)
- [ ] Check: i-status = 0 (no agents active)

**Response Plan** (Priority order):

1. **Diagnose** (10 min)
   ```bash
   CURRENT_I=$(tools/shared/list-sites.sh --batch 001 --status "I" | wc -l)
   CURRENT_O=$(tools/shared/list-sites.sh --batch 001 --status "O" | wc -l)
   CURRENT_i=$(tools/shared/list-sites.sh --batch 001 --status "i" | wc -l)

   echo "I-status (implemented): $CURRENT_I"
   echo "O-status (open): $CURRENT_O"
   echo "i-status (in-progress): $CURRENT_i"

   # Are agents running?
   ps aux | grep -i opus | grep -v grep | wc -l
   ```

2. **Assess** (5 min)
   - [ ] If I == 517 and O == 0: ✅ Work complete, proceed to finalization
   - [ ] If I < 517, O > 0, i == 0: ❌ Agents crashed, need redeploy
   - [ ] If i > 0: ✅ Still processing, wait 15 more min before escalating

3. **Remediate** (depends on assessment)
   - **If complete**: Announce progress, prepare finalization
   - **If agents crashed**: Redeploy remaining agents
     ```bash
     tools/implement/mimplement-bg.sh --batch 001 --max-agents 25 --requeue O
     ```
   - **If resource issue**: Check and clear resources, then redeploy

**Expected outcome**: Agents restarted, I-status resumes increasing

**Impact on schedule**: +30-60 min if agents need redeployment

---

### Scenario 3: Finalization Fails

**Problem**: `finish.sh` command returns error, sites not transitioned to Q

**Root causes**:
- [ ] Registry file missing or corrupted
- [ ] Concurrent write conflict
- [ ] Disk space exhausted
- [ ] Some sites still not at I status
- [ ] Batch metadata missing

**Detection**:
- [ ] finish.sh returns error code
- [ ] Check: sites still not at Q status after command

**Response Plan** (Priority order):

1. **Diagnose** (10 min)
   ```bash
   # Pre-check what finish.sh checks
   echo "Registry exists?"
   ls -l .smbatcher/REGISTRY.md

   echo "All sites at I?"
   NOT_I=$(tools/shared/list-sites.sh --batch 001 | grep -v "| I |" | wc -l)
   echo "Sites not at I: $NOT_I"

   echo "Disk space available?"
   df -h .smbatcher/
   ```

2. **Assess** (5 min)
   - [ ] If sites not at I: Wait for implementation to complete, retry finalization
   - [ ] If registry issue: Check git history, restore if needed
   - [ ] If disk space: Clear temp files, then retry

3. **Remediate** (depends on assessment)
   - **If sites incomplete**: `tools/implement/mimplement-bg.sh --batch 001 --max-agents 25 --requeue i`
     Then retry: `tools/implement/finish.sh --batch 001 --root .`
   - **If registry corrupt**:
     ```bash
     git checkout .smbatcher/REGISTRY.md
     # Or restore from backup
     ```
     Then retry finish.sh
   - **If disk space**:
     ```bash
     du -sh .smbatcher/tmp/
     rm -rf .smbatcher/tmp/*
     ```
     Then retry finish.sh

**Expected outcome**: Finalization completes, all sites transition to Q

**Impact on schedule**: +15-30 min if retry needed

---

### Scenario 4: Site-Specific Implementation Failure

**Problem**: Some sites (e.g., 5 out of 517) fail implementation, stuck at O or i

**Root causes**:
- [ ] Site-specific data issues (invalid characters, special cases)
- [ ] Agent timeout on that particular site
- [ ] Design compliance issues for that site
- [ ] File generation errors specific to that domain

**Detection**:
- [ ] Implementation completes mostly (95%+)
- [ ] A few sites remain at O or i status
- [ ] Example: 512/517 at I, 5 stuck at O

**Response Plan** (Priority order):

1. **Identify stuck sites** (5 min)
   ```bash
   tools/shared/list-sites.sh --batch 001 --status "O"  # Open sites
   tools/shared/list-sites.sh --batch 001 --status "i"  # In-progress sites
   ```

2. **Assess** (5 min per site)
   - Check design: Does DESIGN.md exist?
   - Check logs: Any error messages for that site?
   - Is site fundamentally problematic?

3. **Remediate** (depends on findings)
   - **If < 5 sites stuck**: May be acceptable (< 1% failure)
     - Option 1: Manually implement these sites (quick fix)
     - Option 2: Accept 99%+ completion, document missing
   - **If design issue**: Fix design, redeploy agent for that site
   - **If agent timeout**: Increase timeout, redeploy

4. **Escalation decision**
   - [ ] If <= 1% (< 5 sites): Document and finalize anyway
   - [ ] If 1-5% (5-25 sites): Attempt targeted fix
   - [ ] If > 5%: Escalate, may need design/architecture review

**Expected outcome**: Either fix stuck sites OR accept with documentation

**Impact on schedule**: +30 min if manual fixes, or accept as is

---

### Scenario 5: Complete System Failure

**Problem**: Major system issue (corruption, crash, complete stall) threatens entire project

**Root causes**:
- [ ] Complete disk failure
- [ ] Registry total corruption
- [ ] Database/system-level issue
- [ ] Network completely down (if remote)

**Detection**:
- [ ] System unresponsive or inaccessible
- [ ] Registry file destroyed or unreadable
- [ ] No recovery possible from current state

**Response Plan** (Priority order):

1. **Assess damage** (10 min)
   - [ ] Is system still accessible?
   - [ ] How much data was lost?
   - [ ] Can we recover from backup/git?

2. **Recovery options** (Priority order)
   - **Option 1**: Restore from backup
     ```bash
     git reset --hard HEAD~1  # Go back to last good state
     # Or restore from backup
     ```
   - **Option 2**: Restore from alternate copy of .smbatcher/
   - **Option 3**: Partial recovery (regenerate what's lost)

3. **Remediation steps**
   - Restore registry from version control
   - Verify restored state consistency
   - Identify what was lost
   - Plan for re-processing lost items
   - Restart from recovered checkpoint

4. **Escalation**
   - Notify stakeholders immediately
   - Assess schedule impact
   - Determine if continuing is feasible

**Expected outcome**: System recovered, at worst lose 1-2 hours of progress (version control)

**Impact on schedule**: +2-4 hours depending on recovery method

---

## Part 3: Preventive Measures

### Before Execution Starts

1. **Infrastructure**
   - [ ] Verify sufficient disk space (at least 5GB free)
   - [ ] Verify sufficient memory (at least 2GB free, target 4GB+)
   - [ ] Test network connectivity (if remote execution)
   - [ ] Ensure git is initialized and working

2. **Configuration**
   - [ ] Review and test SIMPLEMENT.md workflow on sample site
   - [ ] Verify SDESIGN workflow on sample site
   - [ ] Test finish.sh on test batch
   - [ ] Verify registry format and atomic operations

3. **Backup & Recovery**
   - [ ] Create backup of .smbatcher/ directory
   - [ ] Verify git history is intact
   - [ ] Document recovery procedures
   - [ ] Test restore from backup (on test environment)

4. **Monitoring**
   - [ ] Set up status monitoring (every 30 min)
   - [ ] Prepare alert thresholds (I-status should increase at X/min)
   - [ ] Prepare logging (record all status checks)
   - [ ] Prepare communication channels (how to reach on-call)

5. **Documentation**
   - [ ] Review all 20 execution guides
   - [ ] Ensure team understands roles and responsibilities
   - [ ] Verify decision trees are accessible
   - [ ] Confirm escalation procedures known to all

### During Execution

1. **Continuous Monitoring**
   - [ ] Check status every 30 minutes
   - [ ] Log all observations
   - [ ] Watch for metric anomalies
   - [ ] Document any issues immediately

2. **Resource Management**
   - [ ] Monitor disk space (warn at 2GB free)
   - [ ] Monitor memory usage (watch for spikes)
   - [ ] Monitor CPU usage (watch for saturation)
   - [ ] Act before critical thresholds reached

3. **Communication**
   - [ ] Report status updates to stakeholders
   - [ ] Escalate issues promptly
   - [ ] Keep team informed of blockers
   - [ ] Document decisions made

4. **Readiness**
   - [ ] Ensure operator is available
   - [ ] Keep decision trees accessible
   - [ ] Keep troubleshooting guide ready
   - [ ] Have backup operator on standby

### After Execution Completes

1. **Verification**
   - [ ] Verify final completion: 566+ sites at Q
   - [ ] Spot-check random sites for quality
   - [ ] Run final verification suite
   - [ ] Document any issues found

2. **Documentation**
   - [ ] Archive all execution logs
   - [ ] Record final metrics
   - [ ] Document any incidents and resolutions
   - [ ] Capture lessons learned

3. **Preservation**
   - [ ] Backup final state (.smbatcher/, sites/)
   - [ ] Archive documentation
   - [ ] Preserve git history
   - [ ] Create project completion summary

---

## Part 4: Escalation Matrix

### Level 1: Observation
**Trigger**: Unusual metric observed (but system still functioning)
**Action**: Document observation, wait 15 min, recheck
**Response**: Monitor more closely, no intervention yet
**Examples**: Slightly slower throughput, minor resource spike

---

### Level 2: Investigation
**Trigger**: Issue persists after 15 min or metric clearly out of range
**Action**: Run diagnostics, identify root cause, attempt minor fix
**Response**: May need to adjust resource allocation or restart component
**Examples**: I-status slow (0.5/min), high memory usage, registry slow

---

### Level 3: Intervention
**Trigger**: Root cause identified, needs corrective action
**Action**: Execute recovery procedure (wave redeploy, restart agents, etc.)
**Response**: May impact 30-60 min schedule
**Examples**: Agents crashed, finalization fails, resource exhaustion

---

### Level 4: Escalation
**Trigger**: Issue not resolvable by standard procedures
**Action**: Halt execution, escalate to project lead
**Response**: May need to accept partial completion or redesign approach
**Examples**: Systemic design flaw, total system failure, major architectural issue

---

## Part 5: Decision Tree for "Should We Continue?"

```
At any point during execution:

START: Something unexpected happens
│
├─ Can we continue execution safely?
│  ├─ YES → Continue, monitor closely, attempt fix if time permits
│  └─ NO → Halt, diagnose, fix before continuing
│
├─ How much work is completed?
│  ├─ < 50% → Consider restart with fixes
│  ├─ 50-95% → Continue if possible, accept partial completion
│  └─ > 95% → Continue, finalize with available data
│
├─ How much time has been invested?
│  ├─ < 2 hours → Low cost to restart
│  ├─ 2-4 hours → Medium cost, fix issues if possible
│  └─ > 4 hours → High sunk cost, continue if feasible
│
└─ Decision Matrix:
    Early + Critical Issue → Restart with fixes
    Early + Minor Issue → Continue with monitoring
    Mid-project + Critical → Fix and continue
    Late-stage + Any Issue → Accept and finalize
    All stages + Irrecoverable → Document and accept partial
```

---

## Part 6: Acceptance Criteria for Project Completion

Project is acceptable if **ALL** of these are met:

✅ **Minimum completion**: >= 566 sites at Q status (99.6%)
✅ **Quality**: >= 95% of implemented sites have valid files
✅ **Compliance**: >= 90% of implementations match design specifications
✅ **No corruption**: Registry integrity verified, no duplicate entries
✅ **Issues documented**: Any failures or deviations documented with reasons

---

## Part 7: What NOT to Do (Anti-Patterns)

❌ **Don't**: Try to fix every site
- Diminishing returns after 95% completion
- Better to document and move on

❌ **Don't**: Restart from scratch if mostly done
- Sunk cost fallacy, but real: 95% done is 95% complete
- Document the 5% and finalize

❌ **Don't**: Ignore monitoring in "steady state"
- Issues develop gradually, early detection is key
- Monitor every 30 min consistently

❌ **Don't**: Skip documentation
- Essential for post-project analysis and improvements
- Future projects depend on lessons learned

❌ **Don't**: Attempt untested recovery procedures
- Always test on small scale first
- Know what you're doing before hitting production

❌ **Don't**: Violate atomic operation principles
- Partial states = data corruption
- Always atomic or not at all

---

## Conclusion

Most risks in WDMaker are **medium likelihood but low impact** - they cause delays but not failures. The key is:

1. **Early detection**: Monitor continuously
2. **Clear procedures**: Know what to do before it happens
3. **Graceful degradation**: Accept 99%+ instead of chasing 100%
4. **Documentation**: Learn for next project

With these contingencies in place, the project can handle most scenarios and still reach successful completion.
