* test: make both suites pass on WindowsChristophe Besson43 hours1-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* feat(files): download a folder as a zip, and remove an empty oneChristophe Besson2026-08-151-0/+191
Two things a Files panel needs and did not have. **Removing a directory** is privileged, where creating one is not: it acts on a name other members are using, on the operator's disk. It is refused unless the directory is empty, and that rule is the safety property — whatever the browser sends, this cannot destroy content. The check runs twice, once before the challenge and once after the signature comes back, because a file can land during the round trip. A file also accepts its uploader's key; a directory has no uploader, so only the operator's key will do. **Downloading a folder** produces a zip built in the browser, written straight to disk as the chunks arrive. An archive of a group folder is routinely tens of gigabytes, so nothing is held: peak memory is one chunk plus a small record per file. The node is not involved at all — it serves the same encrypted chunks as any other download, holds no temporary files, and cannot be asked to compress anything. zipstream.js is store-only. Group content is video and images, already compressed, so deflate would spend CPU on every byte to save nothing, in the thread that is also decrypting. Sizes and CRCs go in a data descriptor after each file because a stream cannot seek back to patch a header, and zip64 kicks in per entry past 4 GiB and for the archive itself. Because none of that can be checked from the Python side of the house, test_zipstream.py runs the real module under Node and reads what it produces with zipfile — CRCs, UTF-8 names, zip64 records and all. The archives also pass `unzip -t`. Firefox and Safari have no File System Access API, so there is nowhere to stream to: the fallback builds the archive in memory and says so, with the size, before starting rather than after failing. One mistake worth recording: the first version of deleteDirectory passed the node's own answer as the value to check the challenge against, which turns the comparison into a tautology. It checks the path we asked for. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
