type Result struct {
	// PathOrig is the path the caller should use as the synthetic
	// --path-orig: <TempDir>/<rel> where rel is the user's --path
	// relative to the git repo root.
	PathOrig string
	// TempDir is the root of the materialized tree. When Persistent
	// is false, caller is responsible for os.RemoveAll once the diff
	// is done. When Persistent is true, the directory lives under the
	// cache root and is meant to be reused across runs — caller MUST
	// NOT remove it.
	TempDir string
	// Persistent reports whether TempDir lives under a content-
	// addressed cache root (and so survives across runs) or is a
	// disposable MkdirTemp directory (legacy behavior). Callers wire
	// cleanup conditionally on this flag.
	Persistent bool
	// Rev is the resolved short SHA of the baseline commit, for
	// logging and error context.
	Rev string
	// Source is a human-readable description of how the rev was
	// picked (e.g. "merge-base with origin/HEAD", "explicit
	// --base=main"), surfaced in the startup log line.
	Source string
	// SelfURLs are the working tree's git remote URLs (raw, unnormalized).
	// The materialized baseline tree carries no .git, so the caller passes
	// these to the baseline render as Config.SelfURLs — the source root
	// represents the same repo, so a self-referential GitRepository aliases
	// to the local tree on the baseline side too.
	SelfURLs []string
