strata19.get_file_diff

What it does

The unified diff for ONE file against a base ref, as real git diff text. Tries <base>...HEAD, then <base>..HEAD, then the uncommitted working tree. Truncation, binary files and no-change are reported as a typed status, never as an empty string the caller has to interpret.

When to use it

Use when: "show me the diff for src/foo.ts" · rendering a file's hunks · inspecting one file out of a reviewed range

Also use when: after strata19.review_pull_request names a file you want to read in full

When not to use it

you want the whole review rollup (use strata19.review_pull_request) or only the list of changed file names (use strata19.graph_from_git_range)
