Each row of the project Files tab gains a download action, and the toolbar
gains a Download ZIP button scoped to the folder being browsed (at the root,
the whole project). Visible to read-only members too: download is a read.
Single files need no new backend: they reuse GET /api/file?force_download.
Directories go through the new GET /api/file/download, which builds the ZIP
on the fly: an async task walks the tree and async_zip (Astral's maintained
rs-async-zip fork) streams entries into a bounded duplex stream backing the
response body — no temp file, no whole-archive buffer, backpressure for free,
and the task dies with the client. Compression is per entry: Deflate at
maximum level, except files whose magic bytes name an already-compressed
format (media/PDF via the shared sniffer, the ZIP family, gzip/zstd/7z/rar,
compressed audio), which are Stored. Entries are prefixed with the folder
name, empty folders and unix permission bits survive, symlinks are never
followed into the archive, and containment stays fail-closed under the
resolved root. Covered by a round-trip test read back with the crate's own
reader (and verified against unzip/python's zipfile).
A source had exactly one live conversation, so the copilot could only ever
replace a chat, never add one: the trash button reset the source and the old
conversation was left orphaned. Working on two things at once meant losing one.
The tab bar now holds two kinds of tab. A primary tab is a source — it shows
whatever `web` or `project-7` currently points at, which is where background
delivery lands (notify, a finished async task, an inbound Telegram message) and
what a reset moves to a fresh row. A secondary tab, opened with `+`, is one
specific conversation: its source points elsewhere, so it is unreachable by
source name and is addressed by id throughout — REST, WebSocket, event
filtering. `POST /api/sessions/new` creates one without touching `sources`,
which is the whole difference from a reset; its agent and run-context still come
from the source, so an extra project tab is the coordinator with the project's
context. Project "Open chat" is untouched and still resumes the project's own.
The load-bearing half is in ChatHub: the input queue and the model pin are now
keyed by session, not by source. Two tabs on one source would otherwise
serialize into a single queue and a single turn, and share a `/model` pin — the
odd one out, since the security group was already per-session and persisted. The
source-taking methods survive as one-line resolvers, so Telegram, mobile and
cron are untouched. Because queues now grow with conversations rather than with
the handful of sources, a reset retires the queue it replaces instead of leaving
a consumer task parked forever.
Events are filtered per conversation, so anything a chat must see has to carry a
session id: `show_file_to_user`'s OpenFile and the security-group revalidation
were emitting untagged and would have reached nobody. A primary connection
additionally follows NewSession for its source, so a second window does not keep
talking to a conversation another window just reset.
Tabs can be renamed by double-click — `chat_sessions.title` existed and was dead
until now. An empty name stores NULL, so the box is also the undo.
Reopening the app closed every project tab: the copilot's tab bar lived in
RAM, so a reload dropped it and each conversation had to be found again from
its project board.
The set of open tabs is now a column on the session row, `chat_sessions.is_open`
(additive, `ensure_column`), restored by `GET /api/sessions/open` and written by
`PUT /api/sessions/{id}/open`. Not localStorage: that store is per-origin, so on
a shared laptop one member's tabs would greet the next, whereas the owner table
sits in their own encrypted file and follows them to another device. Which tab
is *selected* stays in sessionStorage — that one is genuinely per window, and a
shared value would have two windows fighting over it.
`is_open` defaults to 0 and `chat_sessions::create` never sets it: every `/new`
leaves its predecessor behind and every system-agent pass mints a row, so the
opposite default would restore a bar full of conversations nobody opened. Only
the copilot writes the column, at the moment it opens the tab. A reset moves the
flag rather than copying it — `POST /api/sessions` now returns the new id and
`new_session` carries it, and the old row is closed as the new one opens, or the
source would restore twice and a later close would clear the stale row.
Closing a tab clears the flag and nothing else: the conversation is kept and
comes back with its history when the project is reopened.
- GET /api/file returns ETag (mtime+size) + X-Writable on disk files;
PUT /api/file accepts optional if_match -> 409 Conflict on stale version
(last-write-wins preserved when omitted), echoes the new ETag
- FileViewerBase: View | Edit tabs for .md when the caller can write;
source textarea with Save/Cancel, live preview while editing
- Watcher no longer clobbers the buffer mid-edit: while editing with
unsaved changes it probes the server ETag and only raises a conflict
when the remote actually moved on (own-save echo is ignored)
- Conflict banner: Reload remote | Copy mine, then reload | Overwrite
- i18n (en/it/fr) + CSS; docs/projects.md updated
Show file gains image and video display for capable agents. Docs add
projects.md and update index. Wire ws file-watch in project-board.
Minor fs tool and CLAUDE.md updates.
- Strip ~55 stale upstream docs (dev docs never meant for the agents)
- Write new slim index.md as an agent-facing guide to the app's features
- Add new plugin docs: comfyui, elevenlabs, kokoro_tts, orpheus_tts_3b,
remote_connectivity, whisper_local (replacing old names)
- Add docs_host to UserFs: docs/… and ~/docs/… resolve to {WD}/docs,
mounted read-only at /root/docs in every user's container
- Instruct assistant/kid/project-coordinator agents to read docs/index.md
