Public formal-corpus inventory

Lean source inventory.

A source-level census of the complete measured lean/ tree in the private Fieldflux / Concordia repository. This page reports what source existed at the frozen measurement snapshot. Build reachability, theorem authority, and empirical validity are separate scopes.

Scope and counting rules

Every physical *.lean file recursively under lean/ was counted; all 16,911 files in the measured tree were Git-tracked.
Physical line counts include blank lines and comments. Nonblank lines contain at least one non-whitespace character.
Theorem and lemma counts recognize source declarations beginning with Lean theorem or lemma forms after permitted attributes/modifiers, while excluding declarations occurring inside nested block comments or line comments.
example, def, axiom, structure, imported dependency declarations, and declarations merely mentioned in prose are not included in the theorem/lemma totals.
This is a source inventory. It is not a claim that all 16,911 files were compiled by one repository-wide build.

Tier30 source tree

Tier30 is the largest branch in the measured snapshot: 11,268 files and 2,196,702 physical lines. Its immediate recursive branches include Celestial Holography (1,686 files / 274,765 lines), H3 (694 / 206,056), Research (7,501 / 1,226,022), W4 (204 / 73,557), W6 (129 / 35,251), plus 992 direct Tier30 source files (371,075 lines).

Reproducibility

The measurement first established repository identity, active branch, exact Git commit, and clean-worktree status. Physical and tracked file populations were independently compared using recursive filesystem enumeration and Git tracked-file enumeration; both returned 16,911 Lean files. Line totals were accumulated per file. Declaration counting used a source scanner that maintains nested Lean block-comment depth, ignores declarations in comments, recognizes standard declaration modifiers, and aggregates mutually exclusive recursive directory groups.

Verification boundary. Source presence, import reachability, membership in a canonical theorem surface, successful compilation of a named target, theorem-level axiom dependencies, scientific interpretation, and empirical realization are distinct statuses. See the formal verification scope for the public statement of those distinctions.
