TBLite drops the in‑progress transcript when it kills a timing‑out task. The events below were captured turn‑by‑turn by the agent‑loop patch and pieced back together — full content, reasoning, and tool calls are all real; they just came from a different stream than the other tasks.

I'll implement the API endpoint permission canonicalizer step by step.

First, let me understand the requirements and then implement the solution:

→ write_file({"path": "/app/canonicalize.py", "content": "#!/usr/bin/env python3\n\"\"\"\nAPI Endpoint Permission Canonicalizer\n\nTransforms an API endpoint permission configuration into a canonical form\nfollowing access control and endpoint hierarchy semantics with strict validation,\nhard cutoff parsing, and complex permission resolution algorithms.\n\"\"\"\n\nimport re\nimport sys\n\n\ndef normalize_metho…)

Let me test this with a simple input first:

→ write_file({"path": "/app/input.txt", "content": "GET /api/users ALLOW\nPOST /api/users ALLOW\nGET /api/users/{id} ALLOW\nGET /api/users/{id} DENY\n\nbase /api\nexclude admin\n\nGET /api/users/{id}\n"})

The output seems empty. Let me check the output file:

There's an issue with the logic. Let me rewrite the solution with a more careful implementation:

Still empty. Let me debug by checking what's happening:

Good, the parsing is working. Let me trace through the logic more carefully:

→ terminal({"command": "cd /app && python3 -c \"\nimport re\n\ndef normalize_path_for_matching(path):\n    return re.sub(r'\\{[a-zA-Z0-9_-]+\\}', '{var}', path)\n\n# Test path matching\npath1 = '/api/users/{id}'\npath2 = '/api/users/123'\nnorm1 = normalize_path_for_matching(path1)\nnorm2 = normalize_path_for_matching(path2)\n\nprint(f'Path1: {path1} -> {norm1}')\nprint(f'Path2: {path2} -> {norm2}')\nprint(f'…)

I see the issue. The path normalization is correct, but the parent path detection logic is wrong. Let me fix the parent path detection:
