Precursor mathematical reference snapshots

These are selected, author-supplied mathematical source documents mapped into Hypermath on September 7, 2026. They preserve original source bytes except the explicitly identified chapter 36 excerpt. Their original FORM, FRAME, and completeness assertions remain historical claims, not current verification results. They are reference material, not active repository instructions or a runnable dependency tree.

Read the source map and proof audit before using a claim from these documents. The current four root .hm files and the Lean translation are separate artifacts with their own unresolved obligations.

manifest.json records each original path and its Secure Hash Algorithm 256-bit (SHA-256) digest, the imported byte digest, classification, and target correspondence. A digest binds bytes; it does not certify their mathematics. Chapter 36 is limited to source lines 43–149, inclusive. The two identical earlier axioms.hm files share one captured copy.

Git text normalization is disabled for this directory so a fresh checkout retains the bytes bound by the manifest. Original trailing spaces and excerpt boundary blank lines are preserved; they are not formatting changes to the active code or specifications.

The mathematical selection excludes unrelated personal, clinical, business, political, and physical-application material, generated outputs, and archives. Original notices and author attribution are retained. Historic layer names and filenames are evidence locators; current framework terminology is Ordinatics.

To check the snapshots from the repository root:

python -u scripts/check_reference_sources.py

The import script's explicit allowlist documents the selection. It refuses to overwrite differing snapshots; a later source revision requires a separately reviewed capture. The mapping records local working-file bytes, including uncommitted source changes, rather than pretending they all belong to an older Git commit.
