# M2 Batch-2 T2 Execution（Anvil）

- Task: **T2 Stress & Recovery — BLOCK-path validation**
- Executor: ⚙️ Ministry of Works — Anvil (ESTJ)
- Date: 2026-03-08 (Asia/Shanghai)
- Policy refs:
  - `org/m2/M2_BATCH2_TASK_ORDER.md`
  - `org/m2/M2_BATCH2_DISPATCH.md`
  - `org/pilot/gate_check.sh`
  - `org/pilot/gate_config.json`

## 1) Gate Threshold Baseline
From `org/pilot/gate_config.json`:
- `maxTokens=30000`
- `maxRetries=2`
- `maxMinutes=40`

## 2) Verifiable Command Evidence
All commands run from workspace root: `/Users/guchen/.openclaw/workspace`

### Case A — Token overflow should BLOCK
- Command:
```bash
./org/pilot/gate_check.sh 30001 2 40 false
```
- Output:
```text
BLOCK
```
- Return code: `2`

### Case B — Retry overflow should BLOCK
- Command:
```bash
./org/pilot/gate_check.sh 30000 3 40 false
```
- Output:
```text
BLOCK
```
- Return code: `2`

### Case C — Time overflow should BLOCK
- Command:
```bash
./org/pilot/gate_check.sh 30000 2 41 false
```
- Output:
```text
BLOCK
```
- Return code: `2`

### Control Case — Within threshold should PASS
- Command:
```bash
./org/pilot/gate_check.sh 30000 2 40 false
```
- Output:
```text
PASS
```
- Return code: `0`

### Precedence Check — Escalation flag overrides BLOCK path
- Command:
```bash
./org/pilot/gate_check.sh 30001 2 40 true
```
- Output:
```text
PAUSE_AND_ESCALATE
```
- Return code: `3`

## 3) Why T2 should BLOCK (for BLOCK cases)
Per `gate_check.sh` logic:
1. If escalation flag is truthy => `PAUSE_AND_ESCALATE` (exit `3`).
2. Else if any limit exceeded (`tokens > maxTokens` OR `retries > maxRetries` OR `minutes > maxMinutes`) => `BLOCK` (exit `2`).
3. Otherwise => `PASS` (exit `0`).

For T2 BLOCK validation, Cases A/B/C intentionally exceed exactly one threshold each with escalation disabled (`false`), so expected state is **BLOCK** with exit code **2**.

## 4) Dispatch Constraint Compliance
Aligned with `M2_BATCH2_DISPATCH.md`:
- BLOCK tasks are **not executed forward** (must enter repair/recovery queue).
- No gate bypass attempted.
- Evidence retained as command/output/exit-code triplets for audit traceability.

## 5) Acceptance Result
**ACCEPTED (T2 BLOCK-path validation passed).**

Acceptance basis:
- BLOCK path reproduced in 3 independent overflow dimensions (tokens/retries/minutes).
- Exit code semantics match gate contract (`2` for BLOCK).
- PASS control case confirms no false-positive blocking at exact thresholds.

## 6) Reproducible Rerun Commands
```bash
cd /Users/guchen/.openclaw/workspace

# BLOCK by token overflow
./org/pilot/gate_check.sh 30001 2 40 false ; echo "rc=$?"

# BLOCK by retry overflow
./org/pilot/gate_check.sh 30000 3 40 false ; echo "rc=$?"

# BLOCK by minute overflow
./org/pilot/gate_check.sh 30000 2 41 false ; echo "rc=$?"

# PASS control
./org/pilot/gate_check.sh 30000 2 40 false ; echo "rc=$?"

# Escalation precedence check
./org/pilot/gate_check.sh 30001 2 40 true ; echo "rc=$?"
```
