sheaf-preserve

name	sheaf-preserve
description	Produce Ordering and Preservation stalks: edit order, test id, commit, namespace, path — what must not break, in what sequence. Binds to sheaf-kernel. Analog of meta-design in the sheaf-* family. Use when edits must keep public API, tests, and module boundaries. Trigger on "sheaf preserve", "ordering stalk", "preservation stalk", "edit atoms sheaf".

sheaf-preserve

Fills vertices O and P. May run in parallel with sheaf-localize once the kernel graph exists.

Emits

• s_O: { apiRevision, editOrder, testId }
• s_P: { path, commit, namespace }
• Ordered edit atoms that respect O.

Overlaps this skill is responsible for naming honestly

• O–C API revision
• P–C file + commit
• P–L file + namespace
• P–V file
• O–V test identifier

If path casing or a workspace prefix differs from Localization, write the difference. Silent normalization here hides the obstruction from glue.

When not

Greenfield files with no existing contract to preserve.
