Summary

The last gaps found on the twelve repositories under tests-project/, after reading the silent ones by hand.

• Tests first (test: define factory instances, loop else and match), implementation follows.
• Factory instances: a module-level app = create_app() whose callee is a project function, in the module or in another file through the project index, is treated as an instance of what the function's summary returns (return_externals), so app.route resolves to flask.Flask.route and the routes are entry points. MiniBookApiServer creates its application that way; its /img/<name> route passes the parameter to send_file through a helper, a path traversal the analyzer now reports.
• Loop else clauses: the CFG sends the exhausted loop to the else block and break past it, so taint reaching the clause is seen and a break skips it.
• match statements: kept in the HIR with their patterns and laid out by the CFG builder as an if chain over a hidden subject, for literal, singleton, capture, wildcard and or-patterns with guards; sequence, mapping and class patterns are reported per function as unsupported. Flask-Image-Editing-Website was blocked entirely by one match; it is now analysed and reports a hardcoded credential.
• The builder test that used loop else as its unsupported example now uses yield from and starred assignment targets.

All twelve repositories now analyse with no syntax note at all.
