fix: refuse an unsigned handshake challenge

2026-09-28T13:48:04Z

Every node the 4.0 floor admits signs its challenge, and one without a channel binding could not complete the proof anyway, so a missing signature is refused like a wrong one (browser and QUIC client). Co-Authored-By: Claude Opus 5.5

test: make both suites pass on Windows

2026-09-27T20:21:26Z

Most of these failed on Windows for reasons that had nothing to do with the code under test, which is how real Windows defects hid among them: - Read and write files as UTF-8, and talk to Node in UTF-8. read_text(), write_text() and subprocess text=True use the locale codepage, cp1252 on Windows: "é", "—" and "→" arrived as "?" or crashed, some sixty tests. Calls to PowerShell and schtasks are left alone -- they answer in the console codepage. - Import ESM harness modules by file URL (as_uri): a raw "C:\..." path is not a module specifier. - test_cli_golden: mask the tmp path in its JSON-escaped form, spell it the POSIX way, record on Linux, mask the protocol version (the recording had failed everywhere since the MNP 4.0 bump) and argparse's version-dependent quoting; point USERPROFILE at the tmp home, or `member invite` and `operator pair` wrote their codes into the developer's profile. - test_disk_io_off_loop: expect what a free loop can reach on the platform's timer, 15.6 ms on Windows, not an assumed 5 ms. - test_root_paths_are_operator_only: expect the OS's spelling of the path. - test_audio_meta_cache: find ffprobe with shutil.which. Node suite on Windows: 1489 passed, none failed. Hub suite: 3 failures left, all older than this change (two SQLite concurrency tests, one transfer resume). Co-Authored-By: Claude Opus 5.5

test(hub): read the transport wherever it is split

2026-09-25T10:07:49Z

spa_source.transport_files() takes the classic transport*.js scripts from the hub's shell, in load order. Every test that read transport.js reads them all, the Node harnesses run them joined as one scope, the chat probe loads each, and the desktop shell must load them in order.

feat: the node signs its handshake challenge (MNP 3.4)

2026-09-23T15:14:26Z

node_pk in handshake_challenge is now signed over the channel binding and both nonces, so a client can check the node key before a join rather than only at the ack. Both transports; the browser and the QUIC client refuse a wrong signature and treat an absent one as an older node. Co-Authored-By: Claude Opus 5.5
