Calibration code digests must exclude checkout roots
|
| 궁금했던 점
|
Why can byte-identical target-generation artifacts fail validation after moving to a different host checkout?
|
| 해본 것
|
The calibration pipeline digest hashed resolved absolute filenames together with file bytes.
|
| 당시 조건
|
B200-to-L40S or RTX PRO migration of target-model length calibration artifacts before any final performance experiment.
|
| 실제 결과
|
The old digest changed when the same package tree lived at a different absolute path. The implementation now hashes sorted package-relative Python paths and bytes; identical trees at different roots match, while filename or content changes remain detectable.
|
| 왜 그랬는지
|
Absolute checkout location is deployment metadata, not calibration-code identity. Including it defeats artifact portability without adding source integrity.
|
| 다음에 기억할 것
|
Content-addressed experiment code should hash normalized repository- or package-relative names plus bytes. Test identical trees at different absolute roots and fail closed on filename/content changes or an empty code set.
|
| 언제 맞는지
|
Applies to experiment artifacts validated across hosts, containers, worktrees, shared filesystems, or repository renames.
