Module fix_engine 

Deterministic patch planning helpers for lint fixes.

This module intentionally keeps the API small and explicit:

• plan_fixes() selects compatible fixes and records blocked reasons.
• apply_edits() applies byte-range replacements end-to-start.
• protected range helpers mark SQL comments/string literals and template tags.

Structs

BlockedFix

Edit

A single text replacement in byte offsets [start_byte, end_byte).

Fix

A fix proposal, potentially containing multiple edits.

PlanResult

ProtectedRange

Byte range that should not be changed by automatic fix application.

Enums

BlockedReason

FixApplicability

How safe it is to apply a fix automatically.

ProtectedRangeKind

Why a range is protected from automatic edits.

Functions

apply_edits

Apply edits to source by processing from end to start.

apply_fixes

Apply a set of fixes to the source.

derive_protected_ranges

Derive protected ranges from SQL comments/string literals and template tags.

overlapping_edit_pairs

Return overlapping edit index pairs (left, right).

plan_fixes

Plan fixes deterministically and collect blocked reasons.

protected_ranges_from_templates

Derive protected ranges for Jinja-style templated spans.

protected_ranges_from_tokenizer

Derive protected ranges by tokenizing SQL and collecting comment + string tokens.

sort_edits_deterministically

Sort edits in deterministic order.

sort_fixes_deterministically

Sort fixes in deterministic planning order.

touched_protected_ranges

Return protected ranges touched by the provided edits.
