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

fix(node): name a root after its drive when its basename is taken

2026-10-07T23:11:38Z

Two drives with a folder of the same name made the second add fail, and no screen could supply another name. add_root now names it "Name (H)" or "Name (parent)"; a name the operator typed is still refused on a clash. Co-Authored-By: Claude Opus 5.5

chore: bump version to 0.19.0

fix(node): name members admitted without an invitation name

2026-10-07T20:20:45Z

A member who joined by link, by a new device or into an open group was pinned in the roster with no name, so the audit log showed only the first characters of their id. The hub's MNP token now carries the account's username, and after the handshake the node writes it into the roster for an account whose name is empty. An invitation's name is never overwritten; the name is a label, authority stays on `sub`. Co-Authored-By: Claude Opus 5.5

perf(node): list a group's directories off the event loop

2026-10-07T19:31:10Z

Every full index walked all roots on the loop, and a node with several large roots stopped answering for seconds. Walk directories only, on the roots' disk thread; index_sync is spawned and still answers on failure. Co-Authored-By: Claude Opus 5.5

fix(node): drop a directory moved out of the root from the index

2026-10-07T10:48:34Z

Watchdog reports such a move as one "directory deleted" event and nothing for the files, which the indexer ignored until the next reconcile. The freeze rules still apply: root live, directory gone, parent present. Co-Authored-By: Claude Opus 5.5

fix(hub): let a download wait out a reconnect instead of failing

2026-10-07T09:50:48Z

Chunks sent while the reconnect's connect() runs throw at once, and six retries 1.5 s apart ran out before the reconnect landed. Wait for it, up to two minutes, without spending retries. Follow-ups parked in §15.3. Co-Authored-By: Claude Opus 5.5

fix(hub): play video on iPhone through ManagedMediaSource

2026-10-06T21:18:38Z

An iPhone has no MediaSource; every film was refused as an unsupported codec. A browser with neither now says so. Co-Authored-By: Claude Opus 5.5

feat: copy a file's or folder's #/name@owner link from Files, Music, Photos and Search

2026-10-05T10:23:18Z

"Copy link" puts the address group-link.js resolves on the clipboard, on the hub's origin rather than the page's, so a link copied in the desktop application is not app://meshbay. Files offers it for one row, from the right-click menu or the toolbar with one row ticked (a phone's way in); Music on one track's menu, whose dots a phone has; Photos on a right-clicked tile and in the lightbox's bar. The video player and the file preview carry a link button next to Download. Applications get a `linkFor(entry | folderPath)` prop (MESHBAY_DESIGN.md §9.2) and offer the action only when it names a link. The group page builds it from the hub's row; Search from each result's own group and its path before the merged views prefixed it, and names no link for a folder of the merged tree, which a group name alone does not identify. harness/copy_link_probe.py mounts the three applications in Chrome and reads what reached the clipboard.

feat: open a group, a folder or a file from a #/name@owner link

2026-10-05T09:53:57Z

A group can now be reached by the handle shown under its name, and a path after it points inside the group: #/name@owner/root/dir/file downloads the file and opens Files on its folder; a folder opens Files there. The handle is resolved in the client against the account's own /v1/groups/mine, so no hub route answers for a name and nobody can probe for one. While a group is open the address shows the handle (replace, no history entry); a linked path is taken out of the address once acted on, so a reload does not download twice. Signing in no longer sends everyone home: the form stood in for the page the address named, and that is where a link opened signed out was going. group-link.js holds the parsing and lookups, executed whole by test_group_link.py; harness/group_link_probe.py drives the router in Chrome.
