CALL NUMBER: deep_tree_object.mode_type_bits : git_internals_and_the_object_model(1)
DEFINITION: The upper bits of the octal mode identifying the entry's object category: regular file, directory, symlink, or submodule; encoded in the first two octal digits.
Invoke this skill to understand mode_type_bits down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.
THE RELATIVE ROOT (the import cone, by lib)
from deep_tree_object
- executable_file_mode (d1): Mode 100755; regular file with execute bits set; Git marks it this way to preserve the executable bit across platforms that handle it differently.
- regular_file_mode (d1): Mode 100644; standard blob-backed file with read permission for all and write for owner; the default for non-executable files committed to Git.
- subtree_mode (d1): Mode 040000; entry points to a nested tree object representing a directory; the tree entry name contains a forward slash but the slash is not stored in the entry itself.
- symlink_mode (d1): Mode 120000; entry points to a blob object containing the target path as raw bytes; the blob content is the symlink destination, not the link data itself.
from git_internals_and_the_object_model
- submodule_pointer (d1): Entry in a parent repository's tree object referencing a specific commit of a nested repository; stored as mode 160000 with commit SHA-1.

Projected from the git internals and the object model KB (162 concepts / 159 relations) — consistency-typed by MAP; the facet list after the colon IS the cross-lib dependency web.
(leaf — this is an actual skill.)
