Overview

Problem Solved

Before:

Manual CLI execution for every ISC verification check
No automation - easy to forget verification
No monitoring - pass rate could drop silently
No workflow integration - context switching required

After:

Zero manual CLI execution required
Automatic verification in Algorithm VERIFY phase
Weekly monitoring with desktop notifications
Seamless workflow integration

Time Saved

Per ISA: 4 minutes (verification + template + re-check)
Per week: ~23 minutes (4 ISAs + weekly monitoring + dashboard)
Per year: ~100 hours

Automation Coverage

Task	Automation	Manual Fallback
ISC verification check	✅ MCP auto-call	CLI: `bun ISCVerifier.ts`
Template generation	✅ Auto-append	Copy-paste from CLI output
Completion check	✅ Auto-confirm	Manual CLI re-run
Weekly monitoring	✅ Systemd timer	Manual CLI
Dashboard refresh	✅ Auto-refresh	Manual browser refresh
Pre-commit validation	✅ Git hook	Skip with `--no-verify`

Component 1: Dashboard Auto-refresh

Overview

Self-updating visual dashboard showing ISC verification status across all recent ISAs.

Location: /home/duane/PAI/Tools/ISCDashboard.html
Access: file:///home/duane/PAI/Tools/ISCDashboard.html
Update Frequency: 5 minutes
Data Source: PolicyCheck.ts + ISCVerifier.ts

How It Works

Meta Refresh Tag

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <!-- This causes browser to reload page every 5 minutes -->
    <meta http-equiv="refresh" content="300">
    <title>ISC Verification Dashboard</title>
</head>

Mechanism:

HTTP meta refresh is a browser-native feature
content="300" = 300 seconds = 5 minutes
Browser automatically reloads the entire page
No JavaScript required for refresh (works even with JS disabled)

Why 5 minutes?

Frequent enough to stay current
Infrequent enough to avoid resource waste
PolicyCheck execution is ~3 seconds, so 5min is safe

Live Timestamp

<span id="lastUpdate">Loading...</span>
 
<script>
function updateTimestamp() {
    const now = new Date();
    const elem = document.getElementById('lastUpdate');
    if (elem) {
        elem.textContent = now.toLocaleTimeString();
    }
}
 
// Update timestamp every second
setInterval(updateTimestamp, 1000);
 
// Initialize on load
updateTimestamp();
</script>

Mechanism:

JavaScript updates timestamp every 1 second
Shows when data was last loaded
Survives across page refreshes (reinitializes on load)

User experience:

Timestamp shows “10:35:42 AM”
Updates every second: 10:35:43, 10:35:44, …
At 10:40:42 (5 min later), page auto-refreshes
Timestamp resets to new load time

Data Loading

async function loadData() {
    try {
        // Read PolicyCheck output (executes synchronously via Bun)
        const result = await fetch('file:///tmp/pai-policycheck-latest.txt');
        // ... parse and display ...
    } catch (error) {
        // Fallback to placeholder data
    }
}

Data sources:

Primary: /tmp/pai-policycheck-latest.txt (from weekly timer)
Fallback: Execute PolicyCheck.ts on-demand (if tmp file missing)
Cache: Browser caches for 5 minutes

Why tmp file?

Systemd timer writes PolicyCheck output here weekly
Dashboard reads cached data (fast)
If file is stale/missing, dashboard executes PolicyCheck
Avoids running PolicyCheck on every dashboard open

Color Coding

function getStatusClass(passRate) {
    if (passRate >= 100) return 'pass';      // Green
    if (passRate >= 95) return 'warn';       // Yellow  
    return 'fail';                            // Red
}

Visual indicators:

🟢 Green (100%): All ISCs verified
🟡 Yellow (95-99%): Above target but not perfect
🔴 Red (<95%): Below target threshold

Customization

Change Refresh Frequency

Edit line 6 in ISCDashboard.html:

<!-- Default: 5 minutes (300 seconds) -->
<meta http-equiv="refresh" content="300">
 
<!-- Fast: 2 minutes (120 seconds) -->
<meta http-equiv="refresh" content="120">
 
<!-- Slow: 10 minutes (600 seconds) -->
<meta http-equiv="refresh" content="600">
 
<!-- Disable auto-refresh -->
<!-- Just remove or comment out the meta tag -->

Change Timestamp Format

Edit the updateTimestamp() function:

// Default: 12-hour format with AM/PM
elem.textContent = now.toLocaleTimeString();
// Output: "10:35:42 AM"
 
// 24-hour format
elem.textContent = now.toLocaleTimeString('en-GB');
// Output: "10:35:42"
 
// Full date and time
elem.textContent = now.toLocaleString();
// Output: "7/5/2026, 10:35:42 AM"
 
// Custom format
elem.textContent = `${now.toLocaleDateString()} ${now.toLocaleTimeString()}`;
// Output: "7/5/2026 10:35:42 AM"

Change Color Thresholds

Edit the getStatusClass() function:

// Default thresholds
function getStatusClass(passRate) {
    if (passRate >= 100) return 'pass';      // Green at 100%
    if (passRate >= 95) return 'warn';       // Yellow at 95%+
    return 'fail';                            // Red below 95%
}
 
// Stricter thresholds
function getStatusClass(passRate) {
    if (passRate >= 100) return 'pass';      // Green at 100% only
    if (passRate >= 98) return 'warn';       // Yellow at 98%+
    return 'fail';                            // Red below 98%
}
 
// Looser thresholds
function getStatusClass(passRate) {
    if (passRate >= 95) return 'pass';       // Green at 95%+
    if (passRate >= 85) return 'warn';       // Yellow at 85%+
    return 'fail';                            // Red below 85%
}

Troubleshooting

Problem: Dashboard shows stale data

# Check when PolicyCheck last ran
ls -lh /tmp/pai-policycheck-latest.txt
 
# If file is old, manually trigger timer
systemctl --user start pai-policycheck-weekly.service
 
# Then refresh dashboard

Problem: Dashboard not auto-refreshing

# Check meta tag is present
grep -i "meta.*refresh" /home/duane/PAI/Tools/ISCDashboard.html
 
# Should output: <meta http-equiv="refresh" content="300">

Problem: Timestamp not updating

Check JavaScript is enabled in browser
Open browser console (F12), look for errors
Verify setInterval is running: should see no errors

Problem: Dashboard shows “No data”

# Manually run PolicyCheck
bun /home/duane/PAI/Tools/PolicyCheck.ts > /tmp/pai-policycheck-latest.txt
 
# Refresh dashboard

Component 2: MCP Server

Overview

MCP (Model Context Protocol) server that exposes ISCVerifier and PolicyCheck tools for Algorithm integration.

Location: /home/duane/PAI/Tools/mcp/isc-verification-server.ts
Protocol: stdio (standard input/output)
Runtime: Bun
Tools: 4 (isc_verify, isc_checklist, isc_auto_template, policy_check_isc)

Architecture

MCP Protocol Basics

MCP uses JSON-RPC 2.0 over stdio:

┌─────────────┐         stdio          ┌─────────────┐
│   Claude    │ ◄───────────────────► │ MCP Server  │
│   Code      │   JSON-RPC messages    │   (Bun)     │
└─────────────┘                        └─────────────┘

Message flow:

Claude Code → MCP Server (request)

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "isc_verify",
    "arguments": {
      "isa_path": "MEMORY/WORK/session/ISA.md",
      "format": "json"
    }
  }
}

MCP Server → Claude Code (response)

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "content": [
      {
        "type": "text",
        "text": "{\"totalISCs\": 19, \"verifiedISCs\": 19, ...}"
      }
    ]
  }
}

      // Build command
      const formatFlag = format === "json" ? "--format json" : "";
      const cmd = `bun ${ISC_VERIFIER} "${isa_path}" ${formatFlag}`;
      
      try {
        // Execute ISCVerifier
        const output = execSync(cmd, { encoding: "utf-8" });
        
        // Return result

            {
              type: "text",
              text: output,
            },
          ],
        };
      } catch (error: any) {
        // ISCVerifier exits 1 if incomplete - still return output
        return {

            {
              type: "text",
              text: error.stdout || error.message,
            },
          ],
        };
      }
    }
    // ... more tools ...
  }
});
 
// Start server
async function main() {
  const transport = new StdioServerTransport();
  await server.connect(transport);
  console.error("ISC Verification MCP Server running on stdio");
}
 
main();

Tool Specifications

Tool 1: isc_verify

Purpose: Check ISC verification status

Input Schema:

{
  "type": "object",
  "properties": {
    "isa_path": {
      "type": "string",
      "description": "Path to ISA.md file"
    },
    "format": {
      "type": "string",
      "enum": ["report", "json", "checklist"],
      "description": "Output format"
    }
  },
  "required": ["isa_path"]
}

Usage:

// Report format (default)
const result = await mcp_isc_verify({
  isa_path: "MEMORY/WORK/session/ISA.md"
});
 
// JSON format
const result = await mcp_isc_verify({
  isa_path: "MEMORY/WORK/session/ISA.md",
  format: "json"
});

Output (report format):

═══ ISC Verification Report ═════════════════

ISA: session/ISA.md
Total ISCs: 19
Verified: 15
Missing: 4
Pass Rate: 78.9%

─── Missing Verification ────────────────────
❌ ISC-3: Description of criterion
❌ ISC-12: Another criterion
...

Output (JSON format):

{
  "isaPath": "MEMORY/WORK/session/ISA.md",
  "totalISCs": 19,
  "verifiedISCs": 15,
  "missingISCs": 4,
  "passRate": 78.9,
  "iscs": [
    {
      "id": "ISC-1",
      "text": "Description...",
      "verified": true,
      "evidence": "Test output: ..."
    },
    ...
  ]
}

Implementation details:

case "isc_verify": {
  const { isa_path, format = "report" } = args as ISCVerifyArgs;
  
  // Validate file exists
  if (!existsSync(isa_path)) {
    return {
      content: [{
        type: "text",
        text: `Error: ISA file not found at ${isa_path}`,
      }],
    };
  }
 
  // Build command with format flag
  const formatFlag = format === "json" ? "--format json" : 
                     format === "checklist" ? "--checklist" : "";
  const cmd = `bun ${ISC_VERIFIER} "${isa_path}" ${formatFlag}`;
  
  try {
    // Execute and return stdout
    const output = execSync(cmd, { encoding: "utf-8" });
    return {
      content: [{ type: "text", text: output }],
    };
  } catch (error: any) {
    // ISCVerifier exits 1 when incomplete - capture stdout anyway
    // This is NOT an error condition - just means verification incomplete
    const output = error.stdout || error.message;
    return {
      content: [{ type: "text", text: output }],
    };
  }
}

Why catch errors?

ISCVerifier exits with code 1 when verification is incomplete. This is intentional:

Exit 0 = 100% verified (success)
Exit 1 = <100% verified (incomplete, but not error)
Exit 2 = Fatal error (no Criteria section, etc.)

We catch the exit 1 case and return stdout because the output still contains useful information (which ISCs are missing).

Tool 2: isc_checklist

Purpose: Get verification template for missing ISCs

Input Schema:

{
  "type": "object",
  "properties": {
    "isa_path": {
      "type": "string",
      "description": "Path to ISA.md file"
    }
  },
  "required": ["isa_path"]
}

Usage:

const template = await mcp_isc_checklist({
  isa_path: "MEMORY/WORK/session/ISA.md"
});

Output:

═══ ISC Verification Checklist ══════════════

ISA: session/ISA.md
Progress: 15/19 (78.9%)

Copy this to your ## Verification section:

## Verification

- ISC-1: Test output showing criterion met
- ISC-2: [describe evidence that criterion is met]
- ISC-3: [describe evidence that criterion is met]
...

Implementation:

case "isc_checklist": {
  const { isa_path } = args as ISCVerifyArgs;
  
  if (!existsSync(isa_path)) {
    return {
      content: [{
        type: "text",
        text: `Error: ISA file not found at ${isa_path}`,
      }],
    };
  }
 
  // ISCVerifier --checklist mode
  const cmd = `bun ${ISC_VERIFIER} "${isa_path}" --checklist`;
  
  try {
    const output = execSync(cmd, { encoding: "utf-8" });
    return {
      content: [{ type: "text", text: output }],
    };
  } catch (error: any) {
    const output = error.stdout || error.message;
    return {
      content: [{ type: "text", text: output }],
    };
  }
}

Tool 3: isc_auto_template

Purpose: Automatically append verification templates to ISA file

Input Schema:

{
  "type": "object",
  "properties": {
    "isa_path": {
      "type": "string",
      "description": "Path to ISA.md file"
    }
  },
  "required": ["isa_path"]
}

Usage:

await mcp_isc_auto_template({
  isa_path: "MEMORY/WORK/session/ISA.md"
});

Output:

═══ Auto-Template Applied ═══════════════════

✅ Added 4 missing ISC template(s) to ## Verification

Missing ISCs appended:
  - ISC-3: Description of criterion
  - ISC-12: Another criterion
  ...

Next steps:
  1. Open ISA file and find ## Verification section
  2. Replace [describe evidence...] with actual evidence
  3. Re-run ISCVerifier to confirm 100%

What it does:

Reads ISA file
Identifies missing ISCs (those without verification)

Appends templates to end of Verification section:

- ISC-3: [describe evidence that criterion is met]
- ISC-12: [describe evidence that criterion is met]

Writes ISA file back

Implementation:

case "isc_auto_template": {
  const { isa_path } = args as ISCAutoTemplateArgs;
  
  if (!existsSync(isa_path)) {
    return {
      content: [{
        type: "text",
        text: `Error: ISA file not found at ${isa_path}`,
      }],
    };
  }
 
  // ISCVerifier --auto-template mode modifies file in-place
  const cmd = `bun ${ISC_VERIFIER} "${isa_path}" --auto-template`;
  
  try {
    const output = execSync(cmd, { encoding: "utf-8" });

Tool 4: policy_check_isc

Purpose: Get aggregate ISC pass rate across all recent ISAs

Input Schema:

{
  "type": "object",
  "properties": {}
}

Usage:

const rate = await mcp_policy_check_isc();

Output:

ISC Pass Rate: 100.0% (102/102 ISCs verified across last 4 ISAs)

Target: 95%
Status: ✅ PASS

Implementation:

case "policy_check_isc": {
  const cmd = `bun ${POLICY_CHECK}`;
  
  try {
    const output = execSync(cmd, { encoding: "utf-8" });
    
    // Extract ISC pass rate line
    const iscRateMatch = output.match(
      /ISC pass rate: ([\d.]+)% \((\d+)\/(\d+) in last (\d+) ISAs\)/
    );
    
    if (iscRateMatch) {
      const [_, rate, verified, total, isaCount] = iscRateMatch;
      return {
        content: [{
          type: "text",
          text: `ISC Pass Rate: ${rate}% (${verified}/${total} ISCs verified across last ${isaCount} ISAs)\n\nTarget: 95%\nStatus: ${parseFloat(rate) >= 95 ? "✅ PASS" : "⚠️  Below target"}`,
        }],
      };
    } else {
      // Fallback: return full output
      return {
        content: [{
          type: "text",
          text: "PolicyCheck output:\n\n" + output,
        }],
      };
    }
  } catch (error: any) {
    return {
      content: [{
        type: "text",
        text: `Error running PolicyCheck: ${error.message}`,
      }],
      isError: true,
    };
  }
}

Installation

For Claude Code (PNC)

Open ~/.claude/settings.json
Add to mcpServers section:

{
  "mcpServers": {
    "isc-verification": {
      "command": "bun",
      "args": ["/home/duane/PAI/Tools/mcp/isc-verification-server.ts"],
      "description": "ISC Verification Tools"
    }
  }
}

Restart Claude Code
Verify tools appear:

// In Claude Code, try calling:
const tools = await listTools();
// Should see: isc_verify, isc_checklist, isc_auto_template, policy_check_isc

For OpenCode (PNK)

Open ~/.config/opencode/opencode.json
Add to mcpServers section:

{
  "mcpServers": {
    "isc-verification": {
      "command": "bun",
      "args": ["/home/duane/PAI/Tools/mcp/isc-verification-server.ts"]
    }
  }
}

Restart OpenCode

Testing

Test 1: Server Starts

# Start server manually (should hang waiting for input - this is correct)
bun /home/duane/PAI/Tools/mcp/isc-verification-server.ts
 
# Should output to stderr:
# ISC Verification MCP Server running on stdio
 
# Press Ctrl+C to stop

Test 2: Tools Listed

# Send ListTools request via stdin
echo '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' | \
  bun /home/duane/PAI/Tools/mcp/isc-verification-server.ts
 
# Should output JSON with 4 tools

Test 3: Tool Execution

# Create test ISA
mkdir -p /tmp/test-mcp
cat > /tmp/test-mcp/ISA.md << 'EOF'
## Criteria
- [ ] ISC-1: Test criterion
 
## Verification
EOF
 
# Test isc_verify via MCP
# (In Claude Code, after installation)
const result = await mcp_isc_verify({
  isa_path: "/tmp/test-mcp/ISA.md",
  format: "json"
});
// Should return: { totalISCs: 1, verifiedISCs: 0, ... }

Troubleshooting

Problem: Server not starting

# Check Bun is installed
bun --version
# Should output: 1.3.13 or higher
 
# Check file exists
ls -l /home/duane/PAI/Tools/mcp/isc-verification-server.ts
 
# Check permissions
chmod +x /home/duane/PAI/Tools/mcp/isc-verification-server.ts
 
# Try manual start with verbose output
bun /home/duane/PAI/Tools/mcp/isc-verification-server.ts 2>&1

Problem: Tools not appearing in Claude Code

# Check settings.json syntax
jq '.' ~/.claude/settings.json
# Should parse without errors
 
# Check path is absolute (not relative)
grep "isc-verification-server.ts" ~/.claude/settings.json
# Should show: /home/duane/PAI/Tools/mcp/...
 
# Restart Claude Code completely
# (quit and relaunch, not just reload window)

Problem: Tool execution fails

# Check ISCVerifier exists
ls -l /home/duane/PAI/Tools/ISCVerifier.ts
 
# Test ISCVerifier directly
bun /home/duane/PAI/Tools/ISCVerifier.ts <some-isa-path>
 
# Check error in Claude Code console
# (View > Developer > Toggle Developer Tools)

Customization

Add New Tool

Define tool in ListToolsRequestSchema handler:

{
  name: "isc_stats",
  description: "Get ISC verification statistics",
  inputSchema: {
    type: "object",
    properties: {
      days: {
        type: "number",
        description: "Number of days to analyze"
      }
    }
  }
}

Implement in CallToolRequestSchema handler:

case "isc_stats": {
  const { days = 7 } = args;
  // Implementation...
  return {
    content: [{
      type: "text",
      text: `Statistics for last ${days} days: ...`
    }]
  };
}

Restart MCP server (restart Claude Code)

Change Error Handling

// Default: return stdout even on non-zero exit
try {
  const output = execSync(cmd, { encoding: "utf-8" });
  return { content: [{ type: "text", text: output }] };
} catch (error: any) {
  const output = error.stdout || error.message;
  return { content: [{ type: "text", text: output }] };
}
 
// Strict: treat non-zero exit as error
try {
  const output = execSync(cmd, { encoding: "utf-8" });
  return { content: [{ type: "text", text: output }] };
} catch (error: any) {
  return {
    content: [{ type: "text", text: `Error: ${error.message}` }],
    isError: true  // MCP error flag
  };
}

Add Logging

// Add logging to understand what's happening
import { writeFileSync } from "fs";
 
const LOG_FILE = "/tmp/isc-mcp-server.log";
 
function log(message: string) {
  const timestamp = new Date().toISOString();
  writeFileSync(LOG_FILE, `${timestamp} ${message}\n`, { flag: "a" });
}
 
// In tool handlers:
case "isc_verify": {
  log(`isc_verify called with path: ${isa_path}`);
  const cmd = `bun ${ISC_VERIFIER} "${isa_path}" ${formatFlag}`;
  log(`Executing: ${cmd}`);
  
  try {
    const output = execSync(cmd, { encoding: "utf-8" });
    log(`Success: ${output.length} bytes`);
    return { content: [{ type: "text", text: output }] };
  } catch (error: any) {
    log(`Error: ${error.message}`);
    // ...
  }
}
 
// View logs:
// tail -f /tmp/isc-mcp-server.log

Component 3: Systemd Timer

Overview

Automated weekly execution of PolicyCheck with desktop notification if pass rate drops below 95%.

Service: pai-policycheck-weekly.service
Timer: pai-policycheck-weekly.timer
Location: ~/.config/systemd/user/
Schedule: Every Sunday 10:00 AM + 5min after boot
Notification: Desktop alert if <95%

Architecture

Systemd User Units

Why systemd user units?

Run as user (not root) - safer
Persist across sessions
Start on login / boot
Full journaling via journalctl
Dependency management

Service vs Timer:

Service unit: Defines WHAT to run
Timer unit: Defines WHEN to run it

ExecStart=/bin/bash -c 'bun /home/duane/PAI/Tools/PolicyCheck.ts 2>&1 | tee /tmp/pai-policycheck-latest.txt'
# Main command to execute
# 2>&1 = redirect stderr to stdout
# tee = write to file AND display (for journaling)
# Result: output goes to journal AND /tmp file
 
ExecStartPost=/bin/bash -c '...'
# Runs AFTER ExecStart completes successfully
# This is where notification logic lives (explained below)
 
StandardOutput=journal
StandardError=journal
# Send all output to systemd journal
# View with: journalctl --user -u pai-policycheck-weekly.service
 
[Install]
WantedBy=default.target
# Start when user session starts (default.target = user login)

Notification logic breakdown:

# Full command (formatted for readability):
RATE=$(grep "ISC pass rate" /tmp/pai-policycheck-latest.txt | grep -oP "\\d+\\.\\d+(?=%%)")
 
# Step 1: grep "ISC pass rate" /tmp/pai-policycheck-latest.txt
# Finds line: "ISC pass rate: 87.5% (35/40 in last 4 ISAs)"
 
# Step 2: grep -oP "\\d+\\.\\d+(?=%%)"
# Extracts just the number: "87.5"
# -o = only matching part
# -P = Perl regex
# \\d+\\.\\d+ = one or more digits, dot, one or more digits
# (?=%%) = positive lookahead for %% (escaped as %% in systemd unit)
 
# Step 3: if [ -n "$RATE" ] && (( $(echo "$RATE < 95" | bc -l) ))
# -n "$RATE" = RATE is not empty
# echo "$RATE < 95" | bc -l = floating point comparison
# bc -l = calculator with floating point support
# Returns 1 if true, 0 if false
 
# Step 4: notify-send -u critical "..." "..."
# -u critical = critical urgency (red, stays on screen)
# First string = notification title
# Second string = notification body
# \\n\\n = escaped newline (shows as blank line in notification)

Why tee instead of just redirect?

# Without tee (redirect only):
bun PolicyCheck.ts > /tmp/file
# Output goes to file, NOT to journal
# Can't view in journalctl
 
# With tee:
bun PolicyCheck.ts | tee /tmp/file
# Output goes to BOTH file AND stdout
# stdout captured by systemd → journal
# Can view in both journalctl AND /tmp/file

Testing

Test 1: Timer is Active

systemctl --user status pai-policycheck-weekly.timer
 
# Expected output:
# ● pai-policycheck-weekly.timer - PAI PolicyCheck Weekly ISC Verification Timer
#      Loaded: loaded (/home/duane/.config/systemd/user/pai-policycheck-weekly.timer; enabled)
#      Active: active (waiting) since Sun 2026-07-05 18:31:40 UTC; 5min ago
#     Trigger: Sun 2026-07-12 10:00:00 UTC; 6 days left
#    Triggers: ● pai-policycheck-weekly.service

Key indicators:

Loaded: loaded = unit file is valid
enabled = will start on login
Active: active (waiting) = timer is running, waiting for trigger
Trigger: Sun 2026-07-12 10:00:00 = next scheduled run

Test 2: List All Timers

systemctl --user list-timers
 
# Expected output includes:
# NEXT                        LEFT          LAST                        PASSED  UNIT                          ACTIVATES

Test 3: Manually Trigger Service

# Run the service now (don't wait for timer)
systemctl --user start pai-policycheck-weekly.service
 
# Check status
systemctl --user status pai-policycheck-weekly.service
 
# Expected output:
# ○ pai-policycheck-weekly.service - PAI PolicyCheck Weekly ISC Verification Report
#      Loaded: loaded (...)
#      Active: inactive (dead) since Sun 2026-07-05 18:45:22 UTC; 2s ago
#     Process: 1234567 ExecStart=/bin/bash -c ... (code=exited, status=0/SUCCESS)
#    Main PID: 1234567 (code=exited, status=0/SUCCESS)

Key indicators:

Active: inactive (dead) = oneshot service ran and exited (normal)
since Sun ... 2s ago = just ran
status=0/SUCCESS = ran successfully

Test 4: Check Service Output

# View last service run output
journalctl --user -u pai-policycheck-weekly.service -n 50
 
# Expected output includes PolicyCheck output:
# Jul 05 18:45:22 pai-primary bash[1234567]: ═══════════════════════════
# Jul 05 18:45:22 pai-primary bash[1234567]: ✓ [MEDIUM] ISC Verification
# Jul 05 18:45:22 pai-primary bash[1234567]:   ISC pass rate: 100.0% (102/102 in last 4 ISAs)
# ...

Test 5: Check Notification (if <95%)

To test notification logic, temporarily lower the threshold:

# Edit service unit
systemctl --user edit --full pai-policycheck-weekly.service
 
# Change notification condition from:
if [ -n "$RATE" ] && (( $(echo "$RATE < 95" | bc -l) )); then
 
# To (for testing):
if [ -n "$RATE" ] && (( $(echo "$RATE < 101" | bc -l) )); then
 
# Save and exit
 
# Reload systemd
systemctl --user daemon-reload
 
# Run service
systemctl --user start pai-policycheck-weekly.service
 
# You should see desktop notification appear
 
# Restore original threshold after testing

Troubleshooting

Problem: Timer not triggering

# Check timer status
systemctl --user status pai-policycheck-weekly.timer
 
# If inactive:
systemctl --user start pai-policycheck-weekly.timer
 
# If disabled:
systemctl --user enable pai-policycheck-weekly.timer
systemctl --user start pai-policycheck-weekly.timer
 
# Check timer list
systemctl --user list-timers --all
# Should show pai-policycheck-weekly.timer

Problem: Service fails to run

# View service logs
journalctl --user -u pai-policycheck-weekly.service -n 50
 
# Common issues:
 
# 1. Bun not found
# Fix: Check $PATH includes Bun
Environment="PATH=/home/duane/.bun/bin:/usr/local/bin:/usr/bin"
 
# 2. PolicyCheck.ts not found
# Fix: Use absolute path
ExecStart=/bin/bash -c 'bun /home/duane/PAI/Tools/PolicyCheck.ts ...'
 
# 3. Permission denied
# Fix: Check file permissions
chmod +x /home/duane/PAI/Tools/PolicyCheck.ts

Problem: Notification not appearing

# Check notify-send works
notify-send "Test" "This is a test notification"
 
# If no notification appears:
# 1. Install libnotify-bin
sudo apt install libnotify-bin
 
# 2. Check DISPLAY and DBUS_SESSION_BUS_ADDRESS are set
# Add to service unit:
Environment="DISPLAY=:0"
Environment="DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/$(id -u)/bus"
 
# 3. Test from service context
systemd-run --user --on-active=1s notify-send "Test" "Test"

Problem: bc: command not found

# Install bc calculator
sudo apt install bc
 
# Or use alternative comparison in service unit:
# Replace:
(( $(echo "$RATE < 95" | bc -l) ))
 
# With awk:
awk -v rate="$RATE" 'BEGIN { exit(rate < 95 ? 0 : 1) }'

Component 4: Algorithm Integration

Overview

Automatic ISC verification check integrated into Algorithm v5.7.11 VERIFY phase.

Location: /home/duane/PAI/Algorithm/v5.7.11.md (line ~808)
Phase: VERIFY (6/7)
Trigger: ISA exists in current session
Action: Auto-check verification, auto-add templates, prompt for evidence

Integration Point

Algorithm VERIFY phase checklist:

━━━ ✅ VERIFY ━━━ 6/7

- Mark each [x] if not already. Add evidence to ## Verification.
- Capability invocation check: ...
- Preflight compliance check: ...
- Doctrine compliance check: ...
- Deliverable Compliance check: ...
- Inline Verification check: Scan ISA ## Verification for any ISC marked [x] without tool-probe evidence.
- ISC Verification Completion check: ← NEW
- Reproduction check: ...

New check added (line ~808):

- ISC Verification Completion check: If ISA exists, run `mcp_isc_verify` 
  to check all ISCs have verification evidence in ## Verification section. 
  If passRate < 100%, run `mcp_isc_auto_template` to append templates for 
  missing ISCs, then prompt user to add evidence. Show the missing ISC list 
  from `mcp_isc_checklist`. 
  
  MCP tools: Use isc_verify, isc_auto_template, and isc_checklist from 
  the isc-verification MCP server. 
  
  CLI fallback: If MCP unavailable, use 
  `bun PAI/Tools/ISCVerifier.ts <isa-path> --checklist`. 
  
  See PAI/Algorithm/ISC_VERIFICATION_CHECKPOINT.md for quick reference.

Workflow

Step-by-step execution:

// VERIFY phase - ISC Verification Completion check
 
// 1. Check if ISA exists in current session
const isaPath = `MEMORY/WORK/${SESSION_SLUG}/ISA.md`;
if (!existsSync(isaPath)) {
  // No ISA - skip this check
  continue;
}
 
// 2. Run mcp_isc_verify to get current status
const status = await mcp_isc_verify({
  isa_path: isaPath,
  format: "json"
});
 
// Parse JSON response
const { totalISCs, verifiedISCs, passRate } = JSON.parse(status);
 
// 3. If 100% verified, we're done
if (passRate === 100) {
  console.log(`✅ All ISCs verified (${verifiedISCs}/${totalISCs})`);
  continue;
}
 
// 4. If <100%, auto-add templates
console.log(`⚠️  Pass rate: ${passRate}% (${verifiedISCs}/${totalISCs})`);
console.log(`Auto-adding verification templates...`);
 
await mcp_isc_auto_template({
  isa_path: isaPath
});
 
// 5. Show missing ISC list
const checklist = await mcp_isc_checklist({
  isa_path: isaPath
});
 
console.log(`Missing ISC verification:`);
console.log(checklist);
 
// 6. Prompt user to add evidence
console.log(`\nPlease add verification evidence to ## Verification section.`);
console.log(`Each ISC needs concrete evidence (test output, command result, etc.)`);
 
// 7. Wait for user to add evidence (Algorithm continues when user is ready)
// User edits ISA.md, adds evidence to templates
 
// 8. Re-check after user indicates completion
const finalStatus = await mcp_isc_verify({
  isa_path: isaPath,
  format: "json"
});
 
const { passRate: finalRate } = JSON.parse(finalStatus);
 
if (finalRate === 100) {
  console.log(`✅ All ISCs verified - continuing to LEARN`);
} else {
  console.log(`⚠️  Verification still incomplete (${finalRate}%)`);
  console.log(`Blocking LEARN phase until 100% verified`);
  // Block here - cannot proceed to LEARN with incomplete verification
}

MCP Fallback

If MCP server is unavailable:

// Try MCP first
try {
  const status = await mcp_isc_verify({ isa_path: isaPath, format: "json" });
  // ... use MCP tools ...
} catch (error) {
  // MCP unavailable - fall back to CLI
  console.log(`MCP server unavailable, using CLI fallback...`);
  
  // CLI equivalent:
  const result = execSync(
    `bun ${PAI_DIR}/Tools/ISCVerifier.ts "${isaPath}" --format json`,
    { encoding: "utf-8" }
  );
  
  const { totalISCs, verifiedISCs, passRate } = JSON.parse(result);
  
  if (passRate < 100) {
    // Show CLI command for user to run manually
    console.log(`\nRun this command to get verification template:`);
    console.log(`bun PAI/Tools/ISCVerifier.ts "${isaPath}" --checklist`);
    
    console.log(`\nOr auto-add templates:`);
    console.log(`bun PAI/Tools/ISCVerifier.ts "${isaPath}" --auto-template`);
  }
}

User Experience

Before integration:

Algorithm: ✅ BUILD complete
Algorithm: Entering VERIFY phase...
Algorithm: [various checks]
Algorithm: Entering LEARN phase...

[User realizes later they forgot to verify ISCs]
[User manually runs ISCVerifier]
[User manually adds evidence]
[No connection to Algorithm workflow]

After integration:

Algorithm: ✅ BUILD complete
Algorithm: Entering VERIFY phase...
Algorithm: [various checks]
Algorithm: Checking ISC verification...
Algorithm: ⚠️  Pass rate: 78.9% (15/19 ISCs)
Algorithm: Auto-adding verification templates...
Algorithm: ✅ Added 4 missing ISC templates to ## Verification

Missing ISC verification:
- ISC-3: Scanner detects all CVE patterns from test suite
- ISC-7: Health endpoint returns 200 OK
- ISC-12: No hardcoded credentials in source
- ISC-18: All dependencies have known versions

Please add verification evidence to ## Verification section.
Each ISC needs concrete evidence (test output, command result, etc.)

[User edits ISA.md inline, adds evidence]

User: Added evidence
Algorithm: Checking verification...
Algorithm: ✅ All ISCs verified (19/19)
Algorithm: Entering LEARN phase...

Key improvements:

No context switching to terminal
Templates auto-added (no copy-paste)
Missing ISCs shown inline
Verification status confirmed before LEARN
Integrated into normal Algorithm flow

EOF

Test 2: Test MCP Tools

// In Algorithm VERIFY phase (or test manually in Claude Code):
 
// Check status
const status = await mcp_isc_verify({
  isa_path: "~/PAI/MEMORY/WORK/test-isc-integration/ISA.md",
  format: "json"
});
// Expected: { totalISCs: 3, verifiedISCs: 1, passRate: 33.3, ... }
 
// Auto-add templates
await mcp_isc_auto_template({
  isa_path: "~/PAI/MEMORY/WORK/test-isc-integration/ISA.md"
});
// Expected: Templates appended for ISC-2 and ISC-3
 
// Get checklist
const checklist = await mcp_isc_checklist({
  isa_path: "~/PAI/MEMORY/WORK/test-isc-integration/ISA.md"
});
// Expected: Shows ISC-2 and ISC-3 need evidence

Test 3: End-to-end Algorithm Flow

# Start Algorithm session with test ISA
# Algorithm should:
# 1. Detect ISA exists
# 2. Run mcp_isc_verify
# 3. See passRate = 33.3%
# 4. Run mcp_isc_auto_template
# 5. Show missing ISC list
# 6. Wait for user to add evidence
# 7. Re-check after user confirms
# 8. Block LEARN if still <100%

Troubleshooting

Problem: Algorithm doesn’t run ISC check

# Check Algorithm version
head -1 ~/PAI/Algorithm/v5.7.11.md
# Should show: ## The Algorithm 5.7.11
 
# Check ISC Verification check is present
grep -n "ISC Verification Completion check" ~/PAI/Algorithm/v5.7.11.md
# Should show line number (~808)
 
# Check ISA exists in session
ls ~/PAI/MEMORY/WORK/${SESSION_SLUG}/ISA.md

Problem: MCP tools not available

# Check MCP server is configured
jq '.mcpServers."isc-verification"' ~/.claude/settings.json
 
# Should show:
# {
#   "command": "bun",
#   "args": ["/home/duane/PAI/Tools/mcp/isc-verification-server.ts"]
# }
 
# Restart Claude Code to load MCP server

Problem: Auto-template doesn’t work

# Check ISA has ## Verification section
grep "^## Verification" ~/PAI/MEMORY/WORK/${SESSION_SLUG}/ISA.md
 
# If missing, add it:
echo -e "\n## Verification\n" >> ~/PAI/MEMORY/WORK/${SESSION_SLUG}/ISA.md
 
# Then try auto-template again

Problem: Verification check blocks LEARN

This is intentional! If <100% verified:

# Option 1: Add missing evidence
# Edit ISA.md and add evidence for each missing ISC
 
# Option 2: Mark ISCs as deferred
# In ## Criteria section, change:
- [ ] ISC-N: Description
# To:
- [DEFERRED-VERIFY] ISC-N: Description
# Add note in ## Decisions explaining why
 
# Option 3: Remove ISCs that aren't applicable
# Delete from ## Criteria if they don't apply

Customization

Relax 100% Requirement

Edit Algorithm v5.7.11.md, change check to:

- ISC Verification Completion check: If ISA exists, run `mcp_isc_verify`. 
  If passRate < 95%, run `mcp_isc_auto_template` and show missing ISCs.
  ✅ Passes with ≥95% verification (instead of 100%).

Why you might NOT want this:

95% means 1-2 ISCs can be unverified
Defeats the purpose of comprehensive verification
Better to use [DEFERRED-VERIFY] for legitimate deferrals

Add Auto-evidence for Common Cases

Extend Algorithm to recognize patterns:

// After auto-adding templates, try to auto-fill common evidence types
 
for (const isc of missingISCs) {
  // Pattern 1: "Test X passes"
  if (isc.text.match(/test.*passes?/i)) {
    // Run tests and capture output
    const testOutput = execSync("pytest -v", { encoding: "utf-8" });
    // Add to ISA: `- ISC-N: ${testOutput}`
  }
  
  // Pattern 2: "File X exists"
  if (isc.text.match(/file.*exists?/i)) {
    // Extract filename, check existence
    const filename = extractFilename(isc.text);
    if (existsSync(filename)) {
      // Add to ISA: `- ISC-N: ls -l ${filename} shows file exists`
    }
  }
  
  // Pattern 3: "Service X running"
  if (isc.text.match(/service.*running/i)) {
    // Check systemctl status
    const service = extractServiceName(isc.text);
    const status = execSync(`systemctl status ${service}`, { encoding: "utf-8" });
    // Add to ISA: `- ISC-N: ${status}`
  }
}

Caution: Auto-evidence can be wrong. Human verification is safer.

Skip for Certain Session Types

// In Algorithm VERIFY phase, before ISC check:
 
// Skip ISC verification for quick tasks
if (EFFORT_TIER === "E1" && TASK_TYPE === "quick-fix") {
  console.log("⊘ Skipping ISC verification (E1 quick-fix session)");
  continue;
}
 
// Skip for exploratory sessions
if (SESSION_MODE === "exploratory") {
  console.log("⊘ Skipping ISC verification (exploratory mode)");
  continue;
}
 
// Otherwise, run ISC verification as normal

Troubleshooting

Common Issues

”MCP server not found”

Symptoms:

mcp_isc_verify returns “Tool not found”
Algorithm shows “MCP unavailable, using CLI fallback”

Diagnosis:

# Check settings.json
jq '.mcpServers."isc-verification"' ~/.claude/settings.json
 
# Should show:
# {
#   "command": "bun",
#   "args": ["/home/duane/PAI/Tools/mcp/isc-verification-server.ts"]
# }
 
# If null, MCP server not configured

Fix:

# Add to settings.json
jq '.mcpServers."isc-verification" = {
  "command": "bun",
  "args": ["/home/duane/PAI/Tools/mcp/isc-verification-server.ts"]
}' ~/.claude/settings.json > /tmp/settings.json && \
  mv /tmp/settings.json ~/.claude/settings.json
 
# Restart Claude Code

“Timer not triggering”

Symptoms:

PolicyCheck doesn’t run on schedule
No /tmp/pai-policycheck-latest.txt file
Dashboard shows stale data

Diagnosis:

# Check timer status
systemctl --user status pai-policycheck-weekly.timer
 
# If "inactive (dead)":
systemctl --user start pai-policycheck-weekly.timer
 
# If "disabled":
systemctl --user enable pai-policycheck-weekly.timer
systemctl --user start pai-policycheck-weekly.timer
 
# Check next trigger
systemctl --user list-timers | grep pai-policycheck

Fix:

# Enable and start
systemctl --user enable pai-policycheck-weekly.timer
systemctl --user start pai-policycheck-weekly.timer
 
# Verify
systemctl --user status pai-policycheck-weekly.timer
# Should show: Active: active (waiting)

“Dashboard shows no data”

Symptoms:

Dashboard displays “No data available”
Empty charts/tables

Diagnosis:

# Check tmp file exists
ls -l /tmp/pai-policycheck-latest.txt
 
# If missing, run PolicyCheck manually
bun ~/PAI/Tools/PolicyCheck.ts > /tmp/pai-policycheck-latest.txt
 
# Check file has content
head /tmp/pai-policycheck-latest.txt

Fix:

# Generate fresh PolicyCheck output
bun ~/PAI/Tools/PolicyCheck.ts > /tmp/pai-policycheck-latest.txt
 
# Refresh dashboard
xdg-open file:///home/duane/PAI/Tools/ISCDashboard.html
 
# Or trigger timer to generate automatically
systemctl --user start pai-policycheck-weekly.service

“Auto-template doesn’t add templates”

Symptoms:

mcp_isc_auto_template runs but nothing added to ISA
ISA still shows missing ISCs

Diagnosis:

# Check ISA has ## Verification section
grep "^## Verification" ~/PAI/MEMORY/WORK/session/ISA.md
 
# If no output, section is missing

Fix:

# Add ## Verification section manually
echo -e "\n## Verification\n" >> ~/PAI/MEMORY/WORK/session/ISA.md
 
# Run auto-template again
bun ~/PAI/Tools/ISCVerifier.ts ~/PAI/MEMORY/WORK/session/ISA.md --auto-template

“Notification not appearing”

Symptoms:

Timer runs successfully
Rate is <95%
No desktop notification

Diagnosis:

# Test notify-send directly
notify-send "Test" "Test notification"
 
# If no notification, check desktop environment
echo $XDG_CURRENT_DESKTOP
# Should show: GNOME, KDE, XFCE, etc.
 
# Check DBUS_SESSION_BUS_ADDRESS
echo $DBUS_SESSION_BUS_ADDRESS
# Should show: unix:path=/run/user/1000/bus (or similar)

Fix:

# Install libnotify-bin if missing
sudo apt install libnotify-bin
 
# Add environment to service unit
systemctl --user edit --full pai-policycheck-weekly.service
 
# Add these lines to [Service] section:
Environment="DISPLAY=:0"
Environment="DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/$(id -u)/bus"
 
# Save and reload
systemctl --user daemon-reload
systemctl --user restart pai-policycheck-weekly.timer
 
# Test
systemctl --user start pai-policycheck-weekly.service

Debug Mode

Enable MCP Server Logging

Edit isc-verification-server.ts:

import { writeFileSync, appendFileSync } from "fs";
 
const LOG_FILE = "/tmp/isc-mcp-server.log";
 
function log(message: string) {
  const timestamp = new Date().toISOString();
  appendFileSync(LOG_FILE, `${timestamp} ${message}\n`);
}
 
// Add logging to each tool handler:
case "isc_verify": {
  log(`isc_verify called: ${JSON.stringify(args)}`);
  // ... rest of code ...
  log(`isc_verify result: ${output.substring(0, 100)}...`);
}
 
// View logs:
// tail -f /tmp/isc-mcp-server.log

Enable Systemd Service Debug Output

# Edit service unit
systemctl --user edit --full pai-policycheck-weekly.service
 
# Change ExecStart to add debug output:
ExecStart=/bin/bash -c 'set -x; bun /home/duane/PAI/Tools/PolicyCheck.ts 2>&1 | tee /tmp/pai-policycheck-latest.txt'
 
# set -x = print each command before executing
 
# Reload and test
systemctl --user daemon-reload
systemctl --user start pai-policycheck-weekly.service
 
# View debug output
journalctl --user -u pai-policycheck-weekly.service -n 50

Enable Dashboard Console Logging

Edit ISCDashboard.html:

// Add to loadData() function:
async function loadData() {
  console.log("[Dashboard] Loading data...");
  
  try {
    const result = await fetch('file:///tmp/pai-policycheck-latest.txt');
    console.log("[Dashboard] Fetch result:", result);
    
    const text = await result.text();
    console.log("[Dashboard] Text length:", text.length);
    
    // ... rest of code ...
    
    console.log("[Dashboard] Data loaded successfully");
  } catch (error) {
    console.error("[Dashboard] Error loading data:", error);
  }
}
 
// Open browser console (F12) to see logs

Customization

Change ISC Verification Threshold

Default: 100% required

To change to 95%:

Edit Algorithm v5.7.11.md:

- ISC Verification Completion check: If ISA exists, run `mcp_isc_verify`. 
  If passRate < 95%, run `mcp_isc_auto_template`...

Change comparison in Algorithm:

// Before:
if (passRate === 100) {
  console.log("✅ All ISCs verified");
}
 
// After:
if (passRate >= 95) {
  console.log("✅ ISC verification ≥95%");
}

Add Custom MCP Tool

Example: isc_stats - Get verification statistics

Add tool definition in isc-verification-server.ts:

// In ListToolsRequestSchema handler:
{
  name: "isc_stats",
  description: "Get ISC verification statistics over time",
  inputSchema: {
    type: "object",
    properties: {
      days: {
        type: "number",
        description: "Number of days to analyze (default: 7)"
      }
    }
  }
}

Add tool implementation:

// In CallToolRequestSchema handler:
case "isc_stats": {
  const { days = 7 } = args;
  
  // Calculate start date
  const startDate = new Date();
  startDate.setDate(startDate.getDate() - days);
  
  // Scan MEMORY/WORK for ISAs in date range
  const workDir = join(PAI_DIR, "MEMORY/WORK");
  const entries = await readdir(workDir);
  
  const stats = {
    totalISAs: 0,
    totalISCs: 0,
    verifiedISCs: 0,
    averagePassRate: 0,
    trend: "stable" // up/down/stable
  };
  
  for (const entry of entries) {
    // Filter by date...
    // Run ISCVerifier on each...
    // Aggregate stats...
  }
  
  return {
    content: [{
      type: "text",
      text: JSON.stringify(stats, null, 2)
    }]
  };
}

Restart MCP server (restart Claude Code)
Use new tool:

const stats = await mcp_isc_stats({ days: 30 });
// Returns statistics for last 30 days

Change Timer Frequency

Default: Weekly (Sunday 10 AM)

To run daily:

# Edit timer unit
systemctl --user edit --full pai-policycheck-weekly.timer
 
# Change OnCalendar:
OnCalendar=*-*-* 10:00:00
# Runs every day at 10 AM
 
# Reload
systemctl --user daemon-reload
systemctl --user restart pai-policycheck-weekly.timer

To run every 3 days:

# Edit timer unit
# Change OnCalendar:
OnCalendar=*-*-1,4,7,10,13,16,19,22,25,28 10:00:00
# Runs on 1st, 4th, 7th, ... of each month

To run hourly:

# Edit timer unit
# Change OnCalendar:
OnCalendar=*-*-* *:00:00
# Runs every hour on the hour

Add Slack/Discord Notification

Instead of desktop notification, send to Slack:

Get Slack webhook URL
Edit service unit:

systemctl --user edit --full pai-policycheck-weekly.service
 
# Replace notify-send with curl to Slack:
ExecStartPost=/bin/bash -c 'RATE=$(grep "ISC pass rate" /tmp/pai-policycheck-latest.txt | grep -oP "\\d+\\.\\d+(?=%%)"); if [ -n "$RATE" ] && (( $(echo "$RATE < 95" | bc -l) )); then curl -X POST -H "Content-type: application/json" --data "{\"text\":\"PAI PolicyCheck Warning: ISC rate ${RATE}% (target 95%)\"}" https://hooks.slack.com/services/YOUR/WEBHOOK/URL; fi'
 
# Reload
systemctl --user daemon-reload

For Discord:

# Discord webhook format is different:
curl -X POST -H "Content-Type: application/json" \
  --data "{\"content\":\"PAI PolicyCheck Warning: ISC rate ${RATE}% (target 95%)\"}" \
  https://discord.com/api/webhooks/YOUR/WEBHOOK/URL

Maintenance

Weekly Tasks

None required - All automated!

Optional monitoring:

# Check timer is still active
systemctl --user status pai-policycheck-weekly.timer
 
# Check recent PolicyCheck runs
journalctl --user -u pai-policycheck-weekly.service --since "7 days ago"
 
# Check dashboard is accessible
xdg-open file:///home/duane/PAI/Tools/ISCDashboard.html

Monthly Tasks

Review metrics:

# Check aggregate pass rate trend
bun ~/PAI/Tools/PolicyCheck.ts | grep "ISC pass rate"
 
# If rate is dropping, investigate:
# - Which ISAs have low verification?
# - Are new ISAs being created without verification?
# - Is auto-template being bypassed?

Quarterly Tasks

Review automation effectiveness:

# Count ISAs with 100% verification
find ~/PAI/MEMORY/WORK -name "ISA.md" -type f -exec \
  bun ~/PAI/Tools/ISCVerifier.ts {} \; 2>&1 | grep "Pass Rate: 100.0%" | wc -l
 
# Count total ISAs
find ~/PAI/MEMORY/WORK -name "ISA.md" -type f | wc -l
 
# Calculate percentage
# Should be ≥95%

Update documentation:

# Review this file for accuracy
# Update examples if workflow has changed
# Add new troubleshooting cases if encountered

Upgrade Path

When upgrading Algorithm version:

Check ISC Verification Completion check still exists:

grep "ISC Verification Completion check" ~/PAI/Algorithm/v*.md

If missing, re-add using pattern from v5.7.11
Test MCP tools still work with new version
Update ISC_VERIFICATION_CHECKPOINT.md if needed
