* feat(hub): split the group UI into a pluggable "applications" architectureChristophe Besson2026-08-231-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GroupPage's 6620-line app.js carried Chat and Files wedged in directly, with no way to add another group-level app without touching the shell itself. It is now app.js (routing, non-group pages) plus nine focused files — apps.js (the registry), chat-app.js, files-app.js, video-player.js, group-page.js (the shell), group-settings.js, hub-client.js, icon.js and file-utils.js — with docs/apps.md as the checklist for adding one (Videos/Music/Photos are sketched there, not built). Node side gained the matching enablement mechanism, mirroring member_upload exactly: a roster setting, a signed apps_enabled op enforced by _has_admin_authority, exposed in the handshake ack. Operators toggle applications per group from Settings, which also gained a small reorder: Invite, Pairing, Applications, Shared directories, Uploads, danger zone, Your devices, Members. Two bugs surfaced during the split, both missing an import across the new file boundary and invisible to node --check or a module-load probe since they only throw when the code path actually runs: - group-page.js called onRefreshAuth on a stale-token handshake rejection, but app.js never imported refreshAccessToken from hub-client.js — so a brand new member (including a group's own creator) hit "Not a member of this group" and the retry silently failed, throwing before it could refresh the token. - chat-app.js called getLocale() for message timestamps without importing it from i18n.js. Opening Chat on a group with real messages threw mid- render; uncaught, that appears to wedge Preact's render scheduler, so every button on the page stopped responding until reload. Caught the second class of bug with a proper no-undef audit across all split files (a temporarily installed ESLint 9, since the system one is too old to parse this codebase's syntax) rather than trusting grep. 827 tests pass; 6 new ones cover the apps_enabled policy.

* feat(node): the operator can close uploading to everyone but themselvesChristophe Besson2026-08-181-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A group where every member may add files stays the default. Some groups want a library the operator curates, and until now the only way to get one was to designate no upload root at all — which refuses the operator too. **The node enforces it; the interface merely stops offering it.** The Upload button in the Files toolbar and the paperclip in the chat composer both disappear, which is a courtesy to the people who are not trying. The control is `_do_file_upload` refusing with `member_upload_off`, so a member on an old tab, or one speaking MNP directly, gets the same answer. There is a test for each, and the enforcement test is in the node package rather than beside the UI one so nobody reads the hidden button as the mechanism. **Changing it is a signed operator instruction** — `OP_MEMBER_UPLOAD`, on the same path as removing a member. An unsigned one would let any member turn it back on and make the setting a suggestion. The transcript's subject is `on` or `off`: what the operator is shown before signing has to name the outcome, not the operation. **It lives on the node**, in a new `group_settings` table in `roster.db`. Not the hub, which has no business deciding who may write to someone else's disk. Not `node.toml` either: that file is hand-written and full of comments recording decisions, `ops.py` appends to it rather than round-tripping it through a writer, and a setting toggled from a panel must not rewrite the operator's file or need a restart. The value is cached in the group context because the upload path is synchronous, and the signed operation updates both — storing it without applying it would make the panel say one thing while the node did another. **Absent means allowed**, at every layer: no row in the table, no key in the context, no field in `handshake_ack`. An older node and an older client both behave exactly as before, and upgrading never silently closes a group. Each of those three has its own test, because they fail independently. The operator is always exempt — otherwise turning it off locks them out of their own node with a config file and a restart as the only way back. `is_node_admin` was being computed in two places by then and is now one function, since two copies of "is this the operator" is how the ack and the gate come to disagree. A change reaches everyone already connected via `member_upload_ack`, so the button goes without a reconnection. That message is both a broadcast and the reply to the request that caused it, which is why the client does not return early on it. Docs updated for a cold start: draft-v6 §2.1b and change 9, a new "Where Phase 13 stands" section in CLAUDE.md recording what is built, deployed and still missing, the module map row, and desktop-client-v1 §10b on the Settings tab and where group settings live. 883 tests pass.

* docs: settle the desktop client, and draft v6Christophe Besson2026-08-181-0/+270
A design discussion on 2026-08-17 settled Phase 13 and, in doing so, changed four things the spec states. v6 restates only those; v5 stays authoritative for everything it does not touch, per the convention v5 itself used with v4. What changed: * The native shell is **Electron**, not pywebview — structural decision 18 reversed. The SPA depends on Chromium-class APIs (WebRTC, WebCrypto X25519/Ed25519, MSE, Service Workers), so keeping Chromium keeps transport.js, crypto.js, keyderive.js, downloads.js and sw.js *as the client*. A system webview meant reimplementing ~2500-3000 lines. The old "69 % reused" figure was measured against an app.js of ~2600 lines; it is 4586. * A group's content is **several named roots**, not one directory, because the planned video and audio libraries will not live in one folder on one disk. * **Device linking**: one person may hold several devices on a node, admitted by a key the node already pinned and bound by a one-time code the new device generates. Without it a native client is refused where a browser is not, and an account created natively could never be opened in a browser. * **Authorship is authenticated, not asserted** — chat senders sign, uploads have a provable owner, and delete authorization moves from the uploading key to the account. And one rule v5 assumed without writing down: **group-related server state lives on the node.** Verified for multi-root — SwarmSource carries hashes and endpoints, no paths. Also here: the Caddy configuration, which was a snippet in the roadmap that would have broken the SPA (it predates /a/<hash>/ asset versioning and would have 404ed /sw.js, silently killing streamed downloads on Firefox and Safari); and downloads.html, which becomes a security page once a release key exists. Phase 15 was re-read against device linking and is wrong as written: a sender key must be per **device**, never per person, or two devices sharing a chain produce key and nonce reuse — C1 again, one level down. senderkeys.py already fails this silently.
