Module apply_fragment 

Constrained freeform fragment apply (#2018).

Covers Morph-class jobs (lazy snippets, freeform placement) without a Morph clone: Morph-style // ... existing code ... markers are stripped, but placement anchors are required and matching is fail-closed.

Structs

ApplyFragmentSpec

Validated apply-fragment request (anchors required; no free guess).

DesugaredReplace

Fields for building Operation::Replace / replace_text from apply.fragment.

Enums

FragmentPlacement

Placement for a cleaned fragment. Exactly one mode must be chosen.

Functions

Build a validated spec from raw Morph-style inputs.

desugar_to_replace_fields

Desugar a validated spec into replace old + optional insert_after/before + new text.

desugar_to_replace_operation

Build a plan crate::plan::Operation::Replace from a validated apply.fragment spec.

is_lazy_marker_line

True when a line is a Morph-style lazy placeholder (not real source).

plan_apply_fragment_to_replace

Validate raw apply.fragment plan fields and desugar to Operation::Replace.

strip_lazy_markers

Remove Morph-style lazy marker lines; preserve other content and dominant EOL.
