feat: let the operator pause and resume a root's indexing (MNP 6.2)

2026-10-11T22:17:32Z

A whole-root walk now checks its root before every file: removed or ejected, it stops instead of reading the drive to the end; paused, it finishes from the hash cache alone. A paused root is not watched, not swept by reconcile and survives a restart (roster), its indexed files stay served. Resume runs the reconcile sweep over the root, so entries and their enrichment are kept. Signed root_pause / root_resume over MNP, loopback routes, CLI `root pause|resume`, a pause button on the indexing dock and pause/resume in the roots table of Group settings.

feat: let the operator purge a group's chat (MNP 6.1)

2026-10-09T10:17:38Z

Signed chat_purge from the Chat settings deletes every stored message; epoch keys and attachments stay. The ack is broadcast so open chat panels empty. Co-Authored-By: Claude Opus 5.5

perf(node): sample 9 MB with the size above 9 MB, keep known ids

2026-10-07T23:27:58Z

hash_version 3: size + first 4 MB + last 4 MB + 1 MB at the middle, 5.5x faster cold on a USB disk than the 45 MB sample. The cache now serves a hit under whatever version it holds, so no existing id moves. Co-Authored-By: Claude Opus 5.5

refactor(mnp): remove ten operator messages no client sent

2026-10-02T08:51:19Z

node_status, node_settings_set, roster_read, denylist_read, denylist_clear, node_reload and the signed gek_rotate, member_unpin, transfer_limits, group_detach leave MNP 6.0; the Node page and the CLI do this work over loopback. Their ops keep their tests, moved to the ops level. Co-Authored-By: Claude Opus 5.5

feat(mnp): sharing a folder is decided on the node's machine only (MNP 6.0)

2026-10-02T08:20:09Z

root_add, root_update and group_attach leave MNP: adding a directory and switching writable/removable go through the loopback API (native dialog in the desktop app) or the CLI. The operator's Settings tab still lists the roots from any browser, read-only. The desktop app refuses to sign those ops; a loopback flag change now reaches open pages (publish_roots).

refactor: remove dead code across packages

2026-09-28T16:22:07Z

Unused modules, functions, constants and client helpers with no caller, the unreachable hub:probe IPC handler, and the CSAM hash matching. Behaviour unchanged; the dispatch golden loses only the two removed message types. Co-Authored-By: Claude Opus 5.5

refactor: remove the unused GroupIndex.serialize chain

2026-09-28T14:24:12Z

serialize/deserialize had no production caller, and took with them the per-chunk signature, the ChaCha20 cipher variant and the zstandard dependency. Key derivations are unchanged. Docs corrected, including design §4.3's claim that chunks are compressed. Co-Authored-By: Claude Opus 5.5

refactor(node): move file browsing and folder/file ops out of webrtc_server

2026-09-24T14:45:38Z

FilesMixin in transport/webrtc/files.py; the blocking disk helpers join _locate in webrtc/disk.py, and the lease states go to webrtc/limits.py. Co-Authored-By: Claude Opus 5.5

feat(node): invitation links — a code bound to no account until redeemed

2026-09-23T15:31:06Z

New invite kind "link": member of one group, once, never operator, not spendable by an active member, capped at 20 per group, cancellable by handle. Signed ops invite_link_create / invite_cancel, loopback routes, and the known-device join path now accepts a link code. Adds the plan, docs/invite-links.md. Co-Authored-By: Claude Opus 5.5

style: the 98 ruff could not fix, so the linter is a signal again

2026-09-19T12:39:38Z

The pass before this applied ruff's own fixes. These are the ones needing a decision, and the point of doing them is that `ruff check .` now passes: a linter reporting 98 known-acceptable findings reports nothing, because the next real one arrives invisible. **Lines over 100 (70).** Mostly wrapped where they stood. Two exceptions: the aligned trailing comments in `protocol.py`'s message table were shortened rather than wrapped, because wrapping one row of a table breaks the table; and in `models.py` the column comments moved above their columns for the same reason. **Imports below the first statement (14).** `csam.py` kept its FastAPI imports under a section header halfway down the file; two node tests had a constant and a `pytestmark` wedged between two import blocks. Moved, not suppressed. **Bindings nothing reads (4).** Three in tests, where the call stays and only the name goes — `_user(client, "listener")` is there to create the user, not to return one. The fourth was in `revocation.py` and was not a lint finding at all: `_connect_and_listen` opened an httpx stream to the WebSocket URL, did `pass`, and then opened the real connection through the `websockets` library. One pointless request per connect, left over from before that library was used directly. Removed, and `httpx` with it. **`l` as a name (4)**, **semicolons (6)** in the POC spikes, and the rest. 2893 passed, the same count as the two commits before it. `meshbay_node/revocation.py` is worth a decision separately: 154 lines that nothing imports, superseded by `hub_client.maintain_ws`'s `on_revocation`. This commit only stopped it failing the linter. Co-Authored-By: Claude Opus 5
