In `@scripts/check_ext_net_socket_open_invariant.py`:
- Around line 144-145: Remove the newline rejection from the string-scanning
loop so raw newlines inside Rust string literals are accepted; retain the loop’s
EOF handling to detect genuinely unterminated strings.
- Around line 239-244: Update the `paired` check to accept a `has_opened`
assignment only when its innermost enclosing block is the same block as the
receiver’s assignment; nested-block matches must not satisfy the invariant. Add
a self-test confirming an assignment inside a nested `if` triggers the
same-block error.
- Line 44: Update the checker around OPEN_ASSIGNMENT to detect SocketState
initializers that set is_open to true, not just assignments; verify each such
initializer also sets has_opened to true, or reject initializer forms the
checker cannot safely analyze.

- Line 295: Update the initializer-site scan using OPEN_INITIALIZER so it
excludes struct patterns, such as patterns inside matches!, before recording
initializer sites. Add a self_test case for a SocketState pattern and ensure
evaluate does not report it as an initializer missing has_opened.

Exclude turbofish commas when locating matches! arguments.
When a matches! expression uses Result::<SocketState, ()>::Ok(SocketState { is_open: true, ..base }) as its first argument, is_struct_pattern counts the generic-argument comma as a macro separator. It then classifies the initializer as a pattern, and scan_source skips it before checking has_opened: true. A missing field can pass the audit if the remaining sites still meet the seven-site floor. Split macro arguments without treating turbofish commas as separators, and add this case to self_test.

Held from merge train 259: this gate does not pass on current main. The gate is right that the pairing matters, and this is exactly the invariant #11056 asked for. But So please don't resolve this with an exception entry. An exception would assert "this site legitimately leaves Two honest options:
I'd take (1) as the gate change and file (2) as a separate question. Either way the gate must be green on main before it lands, or every subsequent PR inherits a red required context. Ping me and it rides the next train. |
