chore: v2.8.5 — Trash opens on one folder per user, server setup installs S3

- Files → Trash: ONE sidebar entry. An admin's opens on a folder per user's
  Trash (My Trash first, item counts from GET /api/homes/trash, an unreadable
  one showing its error); a folder opens that user's Trash (path bar
  Trash › user, Up back to the folders). An admin may restore/purge in
  another user's Trash (audited); purging asks first. The merged "All users"
  list is gone from the UI.
- A home's Trash is its user's whole recycle bin (home store + host store,
  items tagged `store`).
- `agenthub server setup` installs one Linux user per account on Linux by
  default (`--no-system` opts out); install-system messages drop `sudo`.
- Settings → Git: the author email suggests <username>@<AGENTHUB_EMAIL_DOMAIN>.

+ *   artifact each), **Write** (name, description, instructions) and

+ *   .claude/skills). The user names the skill; the name is previewed as the
+ *   folder and `/command` it installs as (`skillSlug`, the server's rule).
+ * - `PluginAddPanel` — paste a marketplace link (a git https link, a forge
+ *   web link, `owner/repo` or a marketplace.json link), read its plugin list
+ *   and tick the ones to add; or type `name@marketplace` by hand, which is

 - **Folder** — must be absolute, exist and be a directory (`400 EBADPATH`), must not be or contain the OS home (`400 EBADHOME`), and must not be the workspace's own folder or one it already has (`400 EDUP`). Stored by real path. Removing it only drops the row.
+- **Clone** — clones a related repo BESIDE the workspace folder (into its parent; no path is taken from the request) and adds it as a Folder. The clone is `POST /api/lanes/clone`'s own: the same URL allowlist (`400 EBADURL`), one plain `name` (default: the repo's), `409 EEXISTS` for a taken name, run as the folder's account with that account's git identity, `409 ECREDENTIALS` (with `auth: {protocol, host}`) / `ESSHAUTH` / `ENOREPO`; a tool that takes no folders is `400 EUNSUPPORTED`. Answers the view plus `path`. Removing the folder later never deletes the clone. The workspace home's **Add folder** form takes several URLs, one per line, and clones them in turn.
 - **File** — up to 10 MB (`413 ETOOBIG`), not empty (`400 EEMPTY`). AgentHub stores it under `<data dir>/workspace-context/<lane id>/` with a name it derives from `X-File-Name` (directory parts and path characters dropped, `name (2).ext` on a clash), so a request never names a path. It is a COPY taken at upload: later edits to the original are not seen — remove and upload it again, or add its directory as a Folder (read live from disk). Removing it deletes that copy. At most 50 sources per workspace (`400 ETOOMANY`).
 - **Memory** — read-only: the folder's `CLAUDE.md`, `.claude/CLAUDE.md`, `CLAUDE.local.md`, `AGENTS.md`, and for a Claude workspace `<CLAUDE_HOME>/projects/<encoded cwd>/memory/*.md` — `{files: [{label, path, size, mtime, truncated, content}]}`, each at most 256 KB of content.
 - Every write is same-origin only (`403 EBADORIGIN`); an unknown workspace is `404 ENOLANE`, an unknown source `404 ENOSOURCE`.

+
+- **page** — a claude.ai link (`https://claude.ai/…` only, `400 EBADURL`), one row per owner and link. A session's `Artifact` tool publish is captured from its PostToolUse hook (the first `https://claude.ai/…artifact/…` in `tool_response`), owned by the session's workspace owner.
+- **file** — `candidates` are the documents (html, md, pdf, images, csv, office…) the workspace's sessions wrote with Write/Edit/MultiEdit/NotebookEdit, inside its folder. A pin is read under the download route's guards (`lanePath`, `resolveInLane`, `ESECRET`, ≤ 25 MB, `413 ETOOBIG`) and SNAPSHOTTED to `<data dir>/artifacts/<random>/`.
+- **skill** — the caller's own `~/.claude/skills/<name>` (their member home under S3; the host's for an admin or in local mode, else `409 ENOACCOUNT`) or a workspace's `.claude/skills/<name>`. Snapshotted whole: ≤ 300 files, ≤ 5 MB, a symlink anywhere is `ESYMLINK`, a secret-looking file name (`.env`, `*.pem`, `*token*`…) `403 ESECRET`.
+- **file upload** — one file from the user's computer (≤ 25 MB, `413 ETOOBIG`), snapshotted under its own base name (no folder kept).
+- **skill upload / new** — a skill made from files rather than picked: one Markdown/text file of any name becomes `SKILL.md`; several files or a picked/dropped folder (`paths` keeps the layout) need a `SKILL.md` (at the top or in one folder, which is stripped — `400 ENOSKILLMD` otherwise); a single `.zip`/`.skill` is unpacked (sizes checked from its directory first, a symlink entry `ESYMLINK`, `__MACOSX`/`.DS_Store`/`.git`/`node_modules` skipped); an upload holding several skill folders makes one artifact per skill, named by its folder, and stores NOTHING if any of them fails. The `name` the user typed (only for a single skill; else the frontmatter `name:`, the folder or the file name) is made a folder name (`skillSlug`: marks dropped, other characters → `-`; `400 EBADNAME` if nothing is left) and written into `SKILL.md`'s frontmatter as `name:`; a `description` given replaces the frontmatter's, and a skill with none anywhere is `400 ENODESCRIPTION`. Paths are relative with no `..` (`EBADPATH`); the same limits and `ESECRET` as a picked skill. `new` writes `SKILL.md` from `content` the same way.
+- **plugin** — only the spec and its marketplace source (`EBADPLUGIN`, `EBADMARKET`: `owner/repo`, a `validateRemoteUrl` URL, or an https link to a `marketplace.json`); no files. A GitHub web link becomes `owner/repo`, and a forge's `…/src/…`, `…/tree/…`, `…/blob/…` suffix or trailing slash is trimmed. The same `key` added again by its owner updates that row. **inspect** reads the marketplace's `.claude-plugin/marketplace.json` to list its plugins: a git link is cloned shallow, blob-less and without checkout into a temp dir that is removed after, with every credential helper switched off and no prompt (a repository that needs a login is `502 ENEEDLOGIN`; type the key by hand — installing then uses each user's own git login), https only (an ssh link is `400 ESSHMARKET`); a repo with only a `plugin.json` is `400 ENOTMARKET`; unreachable `502 EMARKETFETCH`. It reaches any https host a signed-in user names, like `publish` does — no login is ever sent with it.
+- **Visibility** — local mode: every row, no sharing (`400 ELOCALMODE`). Server mode: a developer sees their own rows and shared ones, admin/analyst every row; only the owner or an admin changes or deletes one (`403 EFORBIDDEN`). `shared` puts a row in every user's **Hub**.
+- **raw** — only a file the snapshot recorded (`404 ENOFILE` otherwise), never a request path; served with `Content-Security-Policy: …; sandbox` and `nosniff`, unknown types as an attachment.
+- **install** — a skill or plugin (`EBADKIND`), into the CALLER's own account: a skill is written to `~/.claude/skills/<name>/` (as the member through `write-as` under S3); a taken name is `409 EEXISTS` unless `replace: true`, which moves the old one to `~/.claude/agenthub-replaced-skills/<name>-<time>/`. A plugin runs `claude plugin marketplace add <market>` then `claude plugin install --scope user <key>` as the caller, never with `-y`. `403 EINSTALLSOFF` while an admin has turned installs off. Share, unshare, a shared row's delete and every install by someone else are written to `audit_log`.
+- Every write is same-origin. The `artifact_changed` broadcast (`{id, ownerId, shared}`) reaches everyone for a shared row, else its owner and staff.

 #### /ws-pty/:runId — PTY frames
 
-A dedicated binary WebSocket stream (not JSON-framed) for tmux-backed PTY transport. Established by the Workspace TerminalView component on workspace load; endpoint is `/ws-pty/:runId` where `runId` comes from `POST /api/run`. Frames are raw PTY output (stdin echoes, command output, prompt updates, terminal control sequences) as binary blobs; the client feeds each frame to xterm.js for live rendering. The same tmux session can have multiple simultaneous clients (browser Workspace, `agenthub workspace shell`, other tools), all receiving the same frames live-synced. **The attach URL carries the client's size** (`/ws-pty/:runId?cols=<n>&rows=<n>`, integers in `[2, 1000]`, else 80×24): tmux resizes the window to whichever client attached most recently, so spawning the attach at a default size and correcting it from the first `resize` message a beat later made the pane's program redraw its whole UI at 80 columns — and everything painted at that width stayed in the scrollback, surfacing as torn left-margin fragments the moment the user scrolled back (issue #33). Resize events after that: the client sends a `{"type":"resize","cols","rows"}` text frame and the server applies it as a `TIOCSWINSZ` ioctl down the pane's pty, so window-sensitive commands (e.g. pagers, text editors) adapt to the viewport size. The client reports its size from **xterm's own `onResize`**, not from the container's `ResizeObserver` — cols also move when the webfont finishes loading or the page zooms, neither of which resizes the observed element — and takes the lead whenever the terminal regains focus. **Several browsers on one pane share ONE size** (`server/lib/pty-attach.js`): tmux's `window-size latest` snapped the pane to whoever typed last, so two viewers on screens of different sizes kept resizing it under each other and one saw it cropped. The server names a DRIVER per pane — the first attach, then whichever sends `{"type":"resize","cols","rows","drive":true}` (the client does on focus and on a keystroke, never on a mouse report). Every other attach is a follower: its PTY is held at the driver's size, a follower's own `resize` without `drive` is remembered but not applied, and the server tells it `{"type":"size","cols","rows"}` — the client resizes xterm to that grid and scales it down with CSS to fit, so the browser in use decides the size and the others just shrink. A follower attaches at the driver's size, so joining never resizes the pane. When the driver's socket closes the rest get `{"type":"lead"}` and size themselves again. Driver tracking is per server process: a real terminal (`agenthub workspace shell`) or a second dashboard on the same tmux still follows tmux's own `latest` rule. Keeping the two widths equal is not cosmetic: a tmux pane **wider** than xterm makes every over-long row autowrap its tail onto the next row's left margin, and tmux never repaints a row it believes unchanged — so stray characters stay glued to the left edge of blank lines, visible as soon as a scroll repaints history. A zero size (the console collapses with CSS, leaving the container 0×0) is never reported. The WebSocket connection inherits the same loopback same-origin guard and optional token auth as other `/api/*` routes. The client re-attaches automatically 1.5 s after an unexpected close (server restart, network blip) — tmux keeps the session alive, so the re-attach repaints the pane in full. It stops retrying only after the server's one-shot `{"type":"exit"}` frame, which means the pane process itself ended — the Workspace takes that frame as the signal to restore the run setup form, since there is nothing left to attach to. Without that retry a dropped socket left the pane frozen on its last painted frame: it still looked live, but no keystroke and no mouse report (wheel scroll included) reached tmux again.

Every other attach is a follower: its PTY is held at the driver's size, a follower's own `resize` without `drive` is remembered but not applied, and the server tells it `{"type":"size","cols","rows"}` — the client resizes xterm to that grid and scales it down with CSS to fit, so the browser in use decides the size and the others just shrink. A follower attaches at the driver's size, so joining never resizes the pane. When the driver's socket closes the rest get `{"type":"lead"}` and size themselves again. On Windows every attach is also sent `{"type":"wheel"}`: psmux never turns mouse tracking on for its client, so the browser sends the SGR wheel report (`ESC[<64;1;1M` up, `ESC[<65;1;1M` down) itself while xterm reports no tracking — psmux scrolls, or forwards it to a pane app that tracks the mouse (Claude Code fullscreen). Driver tracking is per server process: a real terminal (`agenthub workspace shell`) or a second dashboard on the same tmux still follows tmux's own `latest` rule. Keeping the two widths equal is not cosmetic: a tmux pane **wider** than xterm makes every over-long row autowrap its tail onto the next row's left margin, and tmux never repaints a row it believes unchanged — so stray characters stay glued to the left edge of blank lines, visible as soon as a scroll repaints history. A zero size (the console collapses with CSS, leaving the container 0×0) is never reported. The WebSocket connection inherits the same loopback same-origin guard and optional token auth as other `/api/*` routes. The client re-attaches automatically 1.5 s after an unexpected close (server restart, network blip) — tmux keeps the session alive, so the re-attach repaints the pane in full. It stops retrying only after the server's one-shot `{"type":"exit"}` frame, which means the pane process itself ended — the Workspace takes that frame as the signal to restore the run setup form, since there is nothing left to attach to. Without that retry a dropped socket left the pane frozen on its last painted frame: it still looked live, but no keystroke and no mouse report (wheel scroll included) reached tmux again.

+# Artifacts hub — plan
+
+_Drafted 2026-10-14. Status: all three phases built 2026-10-14 (the session view's own Artifacts tab is not built; the page has the per-workspace file picker)._
+
+## Goal
+
+One place to keep what agents PRODUCE, and (in server mode) to share it:
+
+| Kind | What it is | Where it comes from |
+|---|---|---|
+| `page` | A claude.ai Artifact a session published (`claude.ai/…/artifact/…`) | the `Artifact` tool's PostToolUse hook, or a link pasted by hand |
+| `file` | A file an agent wrote (HTML, Markdown, PDF, image, CSV, Office…) | Write/Edit/NotebookEdit hook events, kept on the user's pin; or uploaded from the computer |
+| `skill` | A Claude Code skill folder (`SKILL.md` + files) | the user's own `~/.claude/skills/<name>` or a workspace's `.claude/skills/<name>`; or uploaded (a Markdown file, files, a folder, a .zip/.skill — several skills at once too) or written in the dialog, under a name the user chooses |
+| `plugin` | A plugin by marketplace source + name (no files) | picked from the list a marketplace link answers (`POST /api/artifacts/plugin/inspect`), or typed as `name@marketplace` |
+
+- **Local mode:** one personal library, no sharing UI.
+- **Server mode:** every artifact is the OWNER's and private by default. The owner can **Share** it; a shared artifact appears in the **Hub** for every signed-in user. A shared skill or plugin can be **installed** into the viewer's own account.
+
+## Rules (binding, same spirit as CLAUDE.md)
+
+- **What is shared is a SNAPSHOT, never the owner's live file.** Sharing a `file`/`skill` copies it (size-capped, regular files only, no symlinks followed) into `<data dir>/artifacts/<id>/`, written once like `session_snapshots`. Viewers read only that copy, so no route ever reads another user's home for them. Re-sharing makes a new snapshot.
+- **Nothing shared runs on the dashboard's origin.** HTML/SVG previews are served under the `/git/raw` headers (`sandbox` CSP + `nosniff`) and shown in a sandboxed iframe; a `page` is only a link out, accepted only as `https://claude.ai/…`.
+- **Installing is the viewer's explicit click, into the viewer's own account only.** For a skill, the hub writes the snapshot's files into `~/.claude/skills/<name>/` of the VIEWER (S3: as their member, through `write-as`). It never overwrites an existing skill without `conflict: replace`, and the old one goes to the trash first. For a plugin, the hub runs `claude plugin marketplace add <source>` + `claude plugin install <name>@<market> --scope user` as the viewer (the `applyPluginBaseline` path). The marketplace source passes an allowlist (`owner/repo` or a `validateRemoteUrl` URL), and no argv comes from the request beyond those two validated values.
+- **Before installing, the dialog lists every file of the skill** (a skill may carry scripts that the viewer's agent will run). Every share, unshare and install is written to `audit_log`.
+- **Visibility follows ownership:** a developer sees their own artifacts plus shared ones; admin/analyst see per `scope.js`, like sessions. Unshare removes an artifact from the Hub but does not uninstall copies others already installed.
+
+## Data
+
+New table `artifacts` (`CREATE TABLE IF NOT EXISTS` in `server/db.js`):
+
+`id, kind, title, description, owner_id, lane_id, session_id, source (path | url | market spec), url, snapshot (dir name | NULL), size, shared (0/1), shared_at, installs, created_at, updated_at`, plus an index on `(owner_id, kind)` and on `(shared, kind)`.
+
+## Phases
+
+1. **Library (local + server, private).** Table, `server/lib/artifacts.js`, `/api/artifacts` (list/get/create/patch/delete). `page` rows are captured from the `Artifact` PostToolUse hook (URL taken from `tool_response` by an `https://claude.ai/…artifact/…` match). `file` candidates are listed per workspace from Write events with a document extension, and the user pins them. New **Artifacts** page (sidebar) plus an **Artifacts** tab in the session view's right panel. Scope wiring: `PATH_RULES`, `broadcastAudience`.
+2. **Hub (server mode).** Share/Unshare buttons, snapshot, `Hub` tab, sandboxed preview, download, `artifact_shared` broadcast.
+3. **Skills & plugins.** "Share a skill/plugin" picker, the install flow (S3 included), conflict handling, audit.
+
+Each phase ships with its server and client tests and an update to `docs/API.md`.
+
+## Open questions
+
+- No `Artifact` tool call has happened on this machine yet, so the exact hook payload of a publish is unverified. Phase 1 matches the URL loosely and keeps "paste a link" as the fallback.
+- Should an admin be able to disable Hub installs for everyone (one switch in Settings)? Proposed: yes, on by default.
