|title=<nowiki>Resolving a venv launcher symlink discards virtual-environment identity</nowiki>
|question=<nowiki>Why did the safe-path calibration child reject the project venv even though the command named .venv/bin/python?</nowiki>
|attempt=<nowiki>The runner converted the absolute .venv/bin/python launcher through Path.resolve() before spawning the calibration CLI.</nowiki>
|context=<nowiki>Failed B200 migration bundle b200-2-generation-20260717-a01 at source commit 038c9cd00c25fc83678d4d698f8780bfc5d96369.</nowiki>
|observation=<nowiki>Path resolution produced the base /usr/bin/python3.12 executable, so sys.prefix no longer identified the project .venv. The calibration CLI failed its venv guard 3.4 seconds after Qwen phase start, before any GPU compute process or generation artifact.</nowiki>
|interpretation=<nowiki>The bytes of a venv launcher may be a symlink to the base interpreter, but the lexical launcher path is semantically required for Python to discover pyvenv.cfg and set sys.prefix.</nowiki>
|reusable_lesson=<nowiki>Use an absolute but non-resolved <venv>/bin/python path for subprocess launch. Never resolve the launcher symlink; test sys.prefix or a real CLI guard under the exact safe-path/PYTHONPATH environment before GPU work.</nowiki>
|applicability=<nowiki>Applies to Python virtual environments, safe-path subprocesses, tmux launchers, and experiment runners that normalize executable paths.</nowiki>
|confidence=<nowiki>high</nowiki>
|evidence=<nowiki>Failed decision SHA-256 e1c0e98e2de2fd78fa21acd57aec899ea13f94ffc5707128f9ceb1d87c7ac7eb; child log SHA-256 6c3bc4bd550b39a5ef4657a339f45712448d9756cbf2e949a1210e52bdb75d94; no GPU compute process.</nowiki>
