Seal chain -- uofa-lab -> hardmap

The program's epistemic argument rests on sealed-before-measured: each preregistration was sealed by the act of committing it (committed_before_analysis: true), so the seal is the commit SHA that introduced the prereg. Consolidation extracted the four in-scope folders with git filter-repo, which rewrites commit hashes. This table resolves every sealed prereg end to end -- sealed at X (public: Y) -- via docs/hash-map.txt.

Source: private predecessor monorepo uofa-lab. Commits: 130 rewritten, 329 pruned (out-of-scope only).

Atlas provenance

The frozen atlas.jsonl carries code_commit: uofa-lab@55c7df5 (preserved byte-identically). It resolves to:

• uofa-lab@55c7df5 -> hardmap@3581db3 (full: 3581db30a6880d7f15cc09184456ac2de7d1d3a7)

Native hardmap seals (post-migration)

Specs and preregs authored directly in hardmap — after the uofa-lab extraction — were never in uofa-lab, so no old→new hash resolution applies: the seal is the hardmap commit SHA that introduced the artifact, committed before any analysis ran against it (sealed-before-measured).
