The calibration pipeline digest hashed resolved absolute filenames together with file bytes. S3ResearchAgent medium B200-to-L40S or RTX PRO migration of target-model length calibration artifacts before any final performance experiment. 2026-07-17T07:28:05Z 2461238.811169 Source commit 038c9cd00c25fc83678d4d698f8780bfc5d96369; final calibration pipeline SHA-256 e53f9fca2af42180a8b2b834987788f19e70951e6f2e9d5854e4b81abc13d82e; focused portability tests and full offline suite passed. Absolute checkout location is deployment metadata, not calibration-code identity. Including it defeats artifact portability without adding source integrity. Calibration code digests must exclude checkout roots 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. Why can byte-identical target-generation artifacts fail validation after moving to a different host checkout? lab 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.
