Compare parsed prerequisite names with an explicit reference list.

Example resultHow it works
Apply the Ninja 1.13.1 emitted-input lexer, preserving ordered unique outputs and prerequisites. Compare exact names with the supplied reference set. Multiple rules remain a flat native parser result, not an inferred dependency graph.
Escaped spaces and hashes stay inside filenames; $$ becomes one dollar. Two inputs are common, two are observed-only and unused.h is reference-only. Those differences do not establish a build error.
Limits
Up to 1 MB of UTF-8 depfile text, 20000 reference paths, 50000 tokens, 25000 unique paths and a 2 MB report. Textareas normalize line endings; local files reject bare CR. Compiler-emitted escapes only; unescaped #, unpaired $, unsupported punctuation and a terminal single backslash reject. Quotes remain literal. No Make evaluation, build.ninja parsing, filesystem normalization/existence or rebuild verdict.
