buildfix-domain

Deterministic planning logic for buildfix.

This crate decides what should change from receipts plus repository state. It does not write files.

Core concepts

• Planner: orchestrates fixers and builds BuildfixPlan
• PlanContext: repo/artifact paths + planner policy
• PlannerConfig: allow/deny rules, safety gates, and operation caps
• RepoView: filesystem abstraction for domain logic
• ReceiptSet: indexed lookup over loaded receipts

Built-in fixers

• cargo.workspace_resolver_v2
• cargo.path_dep_add_version
• cargo.use_workspace_dependency
• cargo.consolidate_duplicate_deps
• cargo.remove_unused_deps
• cargo.normalize_rust_version
• cargo.normalize_edition
• cargo.normalize_license

Use builtin_fixer_metas() for stable metadata used by docs/listing surfaces.

Determinism guarantees

• Stable fixer ordering
• Stable operation sorting
• Deterministic IDs
• Normalized path handling (repo-relative, forward slashes)

Boundaries

• No direct markdown rendering
• No direct file mutation
• No CLI concerns

This is a support crate for the buildfix workspace and may evolve in lockstep with the workspace release train.
