improvement(mothership): v0.9 (#6815)
* checkpoint
* Checkpoint
* dot fixes
* Make async tool resume delivery recoverable
* Support split table tools and option recovery
* Harden VFS mutation handling
* feat(platform): platform subagent support — docs corpus VFS, search_docs, account context
Squash of the feat/platform-agent branch (sim side): mounts the Sim docs
corpus in the copilot VFS, wires search_docs and retires the legacy docs
search tools, and syncs the generated tool catalog and trace contracts for
the platform subagent.
* Align Copilot tools and resource handling
* Expand workflow log query support
* checkpoint
* Port desktop-improvements-0 desktop and browser-agent work
* fix(desktop): keep browser-agent input alive through live-SPA re-renders
* Harden workflow sanitization and Slack setup
* feat(desktop): coordinate clicks, caret insertion, and drag for the browser agent
* Revert subagent group eager auto-collapse
* fix(chat): keep sends FIFO across the streaming-to-idle drain gap
* Add the steering backend surface for mid-turn sends
* Sync generated contracts for async subagent orchestration
Pulls the mothership tool catalog (wait_agents / tail_agent / steer_agent /
interrupt_agent), trace spans (chat.async_subagent.*, chat.orchestrate.*), and
trace attributes (copilot.async_subagent.*) into the generated TS contracts.
* Add display titles for the async subagent orchestration tools
wait_agents / tail_agent / steer_agent / interrupt_agent get natural-language
running titles (naming the agent id being waited on, tailed, steered, or
stopped) and a Steering→Steered completed-verb rewrite.
* Show orchestrator-chosen subagent names on agent groups
A subagent_start whose payload data carries a name (the orchestrator's new
name trigger parameter) now labels the agent group with that mission name —
the agent-type icon stays. The name flows through the live stream path, the
turn model (AgentNode.displayName) and its serialize/rebuild round-trip, and
persisted transcripts (PersistedContentBlock.name), so reloads keep the label.
* Improve Copilot error handling and logging
* Backfill the subagent display name from the second start event
The dispatch-time subagent_start fires before the trigger args (and therefore
the name parameter) have streamed; the phase-3 start re-announces the lane with
the name. The block builder was dropping that duplicate wholesale, losing the
name on streaming providers — now it backfills subagentName onto the existing
block instead. (The home turn-model path already reconciled this case.)
* Support Slack bot connection flow
* Harden Copilot error and VFS handling
* Harden VFS resource operations
* Show 'Waiting for the first of N agents' for mode-any waits
The wait_agents title ignored the mode argument, so an any-mode wait over
three agents read 'Waiting for 3 agents' while the model narrated waiting for
the first — contradicting the transcript.
* Collapsed-by-default agent cards with live intent status lines
Subagents now narrate their work through <intent>3-5 words</intent> tags (a
fleet-wide prompt protocol on the mothership side). The turn model streams
each subagent's text through a split-safe tag parser: complete tags update the
agent's currentIntent and disappear from the prose, tags split across deltas
are carried until their close arrives, and a tag that never closes flushes
back as plain text.
The agent card renders as one line — display name (or agent label) plus the
latest intent, replaced inline as the agent shifts gears — and never
auto-expands; expanding to the full tool log is a deliberate click. Only an
outstanding permission prompt or a browser hand-back forces a group open.
Intents persist on the subagent block (and through the legacy persisted-
message paths) so reloads keep the last status, and a renamed reinvocation
now takes the latest name instead of pinning the first.
* Add the internal in-band tool execution route for live mothership turns
POST /api/copilot/tools/execute (INTERNAL_API_SECRET, Go→Sim) runs one
sim-server tool through the same server tool router the resume driver uses
and returns the result synchronously — no checkpoint. This is what lets
background (async) subagents write files/tables/knowledge, and lets the main
lane keep streaming (instead of checkpoint-pausing and killing every
background run) while async agents are live.
* Persist resource side effects for in-band tool execution
Files/tables created through the internal execute route now register on the
chat's resources exactly like the resume driver's executions — the route runs
the same handleResourceSideEffects pass (persistence only; an out-of-band
route has no live event sink, so mid-turn chip pushes are a follow-up).
* Extract intents from group text on every path, sync and async
The turn-model intent filter only fires for span-scoped subagent lanes, but
this surface also delivers subagent text through the legacy block path — so
<intent> tags flowed through unparsed and rendered as prose rows. Groups now
extract intents from their accumulated text at append time: the last complete
tag becomes the card's status line and every complete tag is stripped from
the rendered prose. Covers span-scoped, legacy, and persisted-reload paths
for both synchronous and background delegations.
* Fall back to the live tool title for the agent card status line
Persisted data proved tool-first subagents (grok search agents) emit zero
prose, so intent tags never stream no matter what the prompt says. The
collapsed card now always narrates: the agent's own <intent> tag when present,
else the latest tool's display title while the lane is live.
* Catch subagent <intent> tags in the server relay
The relay's subagent text handler now runs the split-safe intent extraction
as chunks stream: the latest complete tag is stamped onto the lane's persisted
subagent block (subagentIntent) and stripped from the stored prose, so live,
persisted, and replayed views all agree. Per-lane carry handles tags split
across chunks; a never-closing tag flushes back as plain text.
* Drop the tool-title fallback: the status line is the agent's intent
With the intent protocol now injected into every spawn's task message, agents
open with an <intent> tag; the card shows that narration or nothing.
* Replace intents with live tool-title status lines on agent cards
Intent parsing is fully removed (turn model, relay handler, persistence
fields, group extraction). The collapsed card's status is the latest tool
call in its RUNNING phrasing — never the completed rewrite, which stays in
the expanded log. Parallel tools show the most recently started still-running
title with a +N for concurrent siblings; between rounds the last title stays
frozen; a closed lane shows the bare name. Nested agent cards compute their
own status recursively from their own items.
* Keep the main Sim lane live-expanded; collapse only real subagent cards
The mothership group is the turn's own narration, not a delegation card —
collapsing it hid main-lane text and tools until manual expand, which read as
mis-ordered streaming while async subagents interleaved. It keeps the
original live-expand behavior and no status suffix.
* Persist subagent lane lifecycle blocks from the span handler
Lane-scoped span events route to the span handler, which only recorded trace
side effects — no subagent start block was ever persisted (verified: a
seven-agent run stored 104 blocks with zero starts). Grouping then fell back
to keying lane content by agent NAME, so a respawned agent of the same type
merged invisibly into the first one's card until it resolved. The handler now
persists the start block (spanId-keyed and deduped, carrying the display
name) and stamps endedAt on close, giving every invocation its own card.
* Name agents in orchestration titles; '+ n more' overflow format
wait/tail/steer/interrupt titles humanize the slugified agent ids back to
their display names ('Waiting for the first of Digest Workflow Build + 4
more'), and the agent card's parallel-tool suffix uses the same '+ n more'
format.
* Harden in-band tool execution and resources
* Route in-band execution through the comprehensive tool dispatcher
The internal execute route used the bare server-tool router, which rejects
VFS tools with 'Unknown server tool: read/glob/grep' — so nearly every
background agent's first discovery call failed (102 in-band calls in one run,
dozens rejected). It now uses the relay's executeTool dispatcher: registered
handlers (VFS, function execute) with permission checks and param
normalization, falling back to the app tool router — the same surface
foreground execution gets.
* Harden chat stream transition handling
* Harden VFS provenance and resource writes
* Standardize tool environment references
* Harden browser panel and chat cleanup
* Descriptive, user-language tool titles across the board
House rules applied everywhere: use every argument the call carries, never
name internal machinery, and never lead with Getting (the Got rewrite is
deleted so it cannot return).
- Deployments name the workflow: Deploying {workflow} as API/chat app/MCP tool
- Workflow reads name the part: Reading {workflow} meta/state/deployment/notes;
generic reads always name the file (Reading {leaf}), never bare Reading file
- Block runs name block and workflow: Running {block} in {workflow}, Running
from {block} in {workflow}, Running {workflow} until {block}, and
Enabling/Disabling {block} in {workflow}
- The six split-table tools get per-operation verbs (Adding column {name},
Updating rows, Wiring automation, Creating view {name}) instead of a wall
of Querying table
- The manage quartet drops X-action system-speak for gerunds
- get_* internal names become user language (Checking run settings, Tracing
block inputs, Reading the deployed version); web_fetch says Fetching
- Scheduled-task titles removed entirely (feature deleted from the Go catalog)
- New verb rewrites: Fetched, Traced, Wired, Configured, Looked, Rotated
* Deploying {workflow} as chat, not as chat app
* Loader gerunds; mv names both ends; mkdir names the folder
search_integration_tools -> Finding the right integration;
load_integration_tool -> Loading {integration} tools; load_skill ->
Loading skill {name}; run_enrichment -> Looking up {subject}. mv prefers the
model's phrasing, else reads 'Moving {files} to {destination}'; mkdir reads
'Creating folder {name}' from the path.
* Overflow counts read '+ n', dropping 'more'
* Unify workspace find and search
* Scale desktop title bar with page zoom
* Serialize account and organization truth into the copilot VFS
Workspace standing, membership, billing, org role, access-control
restrictions, published-block provenance, and fork topology were reachable
only through three parameterless tools (or not at all). They are ambient
read-only facts, so they belong in the VFS where they are greppable, cost no
tool round-trip, and every agent that can read gets them — the same move that
retired get_blocks_and_tools and list_user_workflows.
Adds account/{workspace,workspaces,members,billing}.json (always mounted) and
organization/{organization,access-control,custom-blocks,forks}.json (only when
the workspace is org-hosted). Every file projects an existing use case or util
after getOrMaterializeVFS's access assert — no new queries, no new
authorization. One relation per file, cross-referenced by id-and-name stub, so
overlapping facts cannot disagree. Volatile content (billing, access control,
forks) is lazy, so numbers are read-time fresh and unasked-for reads cost
nothing.
Projection follows the viewer: member emails are admin-only, fork detail
requires workspace admin on a forking-enabled org, and the whole organization/
namespace is absent for a personal workspace — which is itself the answer.
Retires get_account_billing, get_enterprise_context, and list_user_workspaces
along with their handlers; display titles stay for transcript replay.
* Fix insert_text refusing an editable field focused inside a frame
describeFocusedEditable descended shadow roots but not frames, while
activeElementReadback descends both. Focus inside a same-origin frame therefore
surfaced to the first as the FRAME element — not an input, not contentEditable,
not a canvas, no textbox role — so it fell through to 'not-editable' and
insert_text refused a field that press_key had just typed a character into.
Two functions answering 'what is focused' with different answers is the bug;
the descent loops now match exactly.
The refusal also names what actually held focus (tag, role, contenteditable).
A bare 'not-editable' gave the agent nothing to act on, so it guessed at the
cause — a real run spent twenty rounds on the wrong theory and had to be
stopped by the user.
* Keep retired browser takeover renderable in history
The tool is gone from the catalog, so its generated constant went with it and
every path that referenced it stopped compiling. Deleting those paths instead
would have silently downgraded every past transcript containing a takeover card
to a generic tool row, and dropped the no-timeout budget that an in-flight
takeover still needs while a rolling deploy finishes.
retired-tools.ts gives the literal a documented home that says what it is and
why it survives its tool.
* Follow the agent into a tab it opened to work in
browser_open_tab created the page with activate: false, so the agent worked in
a tab the user could not see while the panel sat on a page where nothing was
happening. The panel now follows a tab the agent deliberately opened.
Scoped to that tool only. A page spawning its own tab (popup, target=_blank) is
the site grabbing the view rather than the agent choosing a workspace, and
stays in the background as before — two existing tests pin that and caught the
first version of this change, which moved both.
A tab the user claimed still wins over both: the work starts in the background
instead of pulling the page out from under them mid-read.
* Make the browser tools agree with each other
An audit of the module found the frame-descent bug was one instance of a
pattern: six independent definitions of 'is this editable' and seven of 'what
is focused', disagreeing with each other. A tool refusing what its sibling
accepts on identical page state is invisible at runtime — the agent follows a
snapshot that says one thing into a tool that says another.
- browser_type now accepts role="textbox" like browser_insert_text does. The
snapshot advertises those elements as [textbox] with a ref, so refusing them
meant rejecting exactly what the outline told the model to type into. Both
the native and synthetic paths, and their descendant scans.
- pressKeyOnPage descends shadow roots and frames like every other focus
reader. It was dispatching synthetic keys at the shadow host or <iframe>
element, where they bubble but never reach the editor, while reporting
success — and contradicting the activeElement reported beside it.
- not-editable and ambiguous-editable name what was found: the element's tag
and role, and the candidate fields. Both had the data and discarded it, which
is what turns one blocked step into twenty rounds of guessing.
- obstructedAfterNavigation requires a dialog that ARRIVED with the
navigation. It compared against nothing, so every SPA route change under a
persistent role=dialog reported a successful click as obstructed. The test
that covered this asserted the false positive; it now pins both directions.
- browser_insert_text observes the top document when typing inside a frame,
like every other input tool. A submit that navigates the top page was
invisible to its frame-scoped observation.
* Let hover actually see what it mounted
Four independent defects made browser_hover blind to the most common thing a
hover produces — a row's action bar — so it reported no effect on a hover that
worked, and the agent fell back to clicking pixels off screenshots.
- The popup scan matched only role=tooltip/menu/listbox. Slack's message
shortcuts bar is a labelled toolbar/group, so it registered as nothing at
all. Added toolbar, menubar, labelled group, and [popover].
- The baseline was captured BEFORE prepareElementSurface scrolled the target
into view, so scrollChanged was always set by the tool's own probe. That
pinned every unproductive hover to 'background DOM churn' instead of the
honest 'nothing happened', and hid scrolling the hover really caused.
Re-baselined once the scroll settles and before the pointer moves.
- The MutationObserver attached only on the first observation, while the roots
list is rebuilt every call and grows as shadow roots mount. Components that
appeared later were never observed, so their DOM changes raised no revision.
Roots are now observed as they show up.
- observationTruncated was computed and never read, so a scan capped at 12k
nodes reported 'nothing appeared' with the same confidence as a complete
one — and portalled overlays live at the end of <body>, exactly what the cap
drops. Hover now says the page was too large to scan and to confirm visually.
* Stop the browser agent acting on the wrong element, and say why it refused
Four findings from the module audit, the first of which could silently do the
wrong thing rather than merely fail.
- A ref whose node is gone is re-adopted by structural resemblance, matching on
ORIGIN only so a pushState between snapshot and act does not kill every ref.
That leniency also let a ref to a row control in one view rebind to the
identical control in a view the app had since navigated to — acting on the
wrong message, signalled by nothing louder than recovered: true. Adoption now
requires the same path; a view swap reports the ref stale, and the caller
re-snapshots. Revalidating a still-connected node stays lenient, because that
is literally the node the model chose.
- A hit INSIDE the requested element is its own nested control, not an overlay.
Both produced 'covered by X — close or move the overlay', advice that cannot
be followed because there is nothing to close. Nested hits now say so and
point at retargeting.
- browser_click_at, browser_insert_text, and browser_drag listed targetChanged
in their effect formulas, but none passes an elementId, so no targetState is
ever captured and the term was always false — coverage that read as real.
Removed, with a test pinning the dependency.
- The seven effect formulas are deliberately NOT collapsed into one predicate:
drag must trust domChanged where others must not, hover must ignore field and
focus changes, click counts focus only for editables. Forcing one would make
each tool wrong differently. The differences are now documented in one place
next to the shared computation, so divergence is a declared policy rather
than an accident.
* Let edit_workflow configure block retries
* Updates
* Always focus the resource the agent is working on, and its browser tab
The resource panel had a carve-out: an already-open browser session declined
to replace another selection and only got an attention marker, so agent
browser work happened off-screen. The panel now follows the agent to whatever
it touches — browser included — and an event can still opt out explicitly.
The browser panel also follows the agent BETWEEN tabs: the store already
tracked automationTabId (and the strip marked it), but the visible tab never
changed. It now switches when the agent's target tab changes, so watching the
agent never means hunting for the tab it moved to. Keyed on the target
changing rather than on it being set, so a user who browses elsewhere
mid-run is only pulled along when the agent itself moves.
* Never paint a browser snapshot at stale geometry (the modal-open flash)
Opening a modal locks scroll, which removes the window scrollbar and reflows
the panel — so a capture taken before the lock describes a rect the panel no
longer occupies. The handshake painted that frame anyway and only then
retried, so the replacement landed visibly offset from the page it stands in
for: the flash. A capture is now checked against the host's live rect before
it is painted; a mismatched frame is skipped and re-captured at the settled
layout instead (modal retries go 2 -> 3 to absorb the extra settle).
* Name the workflow in deployment and workflow-scoped tool titles
'Checked deployment status' never said which workflow — nor did the deployed-
state read, run settings, block outputs/inputs, redeploy, promote, or the
global-variable write. These tools carry a workflowId (often defaulting to the
current workflow), so only the client can resolve a name: the enrichment layer
now resolves it for the whole workflow-scoped family and passes it as
workflowName, which every workflow title already reads.
Titles: Checking {workflow} deployment status, Reading deployed {workflow},
Checking {workflow} run settings, Reading {workflow} block outputs, Tracing
{workflow} block inputs, Redeploying {workflow}, Promoting {workflow} version
{n} to live, and 'Adding workflow variable {name} in {workflow}' — each
falling back to its unnamed form when no workflow resolves.
* Name the block that ran; never fall back to a raw block id
run_block and set_block_enabled carry only a blockId, so their titles would
have printed an opaque UUID ('Running 7f3a2b91-… in Invoice Sync'). The
enrichment layer now resolves blockId against the workflow store the same way
it already did for run_from_block's startBlockId, and the base titles no
longer accept an id as a name — an unresolved block reads 'Running block'
rather than a UUID.
* Add the missing Removing -> Removed rewrite
The table work introduced 'Removing automation'/'Removing enrichment' with no
past form, so those rows kept their present tense after completing.
* Name the target resource in the remaining tool titles
Table tools keep their operands nested under args and identify the table by
id, so their rows said 'Adding rows' with no hint where: enrichment now lifts
the nested args and resolves tableId against the cached workspace table list,
giving 'Adding rows to Runtimes', 'Adding column status in Runtimes',
'Reading views of Runtimes'.
Also: a block-schema read names the block instead of the file ('Loading
Slack', 'Loading Google Sheets tips'); browser type/insert show the text they
send, middle-ellipsized; downloads name the file; library-docs searches name
the library and query; knowledge-base searches include the query; generated
media names its output file; and diff_workflows, list_deployment_versions,
and publish_custom_block joined the workflow-name enrichment set.
* Bubble nested agents' tool calls into the parent's status line
The collapsed status only scanned a group's OWN tool items and skipped nested
agent groups, so a parent that had delegated froze on its last own tool while
its child did the actual work — the line described nothing that was running.
Status now walks the whole subtree: any tool at any depth counts, the most
recently started running one is shown, and the rest become the same '+ n'
overflow. With nothing running it falls back to the last tool at any depth,
so an idle parent still reflects where its subtree got to.
* Align nested tool call status rows
* Revert branch-local KB connector error-message edits

chore(deps): upgrade next to 16.3.0 and clean up the TypeScript toolchain (#6235)
Bumps next, @next/env and the @next/swc-* optional deps to 16.3.0 across the root overrides, apps/sim, apps/docs and packages/emcn. Two config notes worth keeping: - `experimental.turbopackFileSystemCacheForBuild`'s default flipped false -> true for stable in 16.3.0, so our explicit `false` is now load-bearing rather than defensive. Without it this bump would have silently re-enabled a build cache measured 3.2x slower on this codebase (#6078). Comment updated to say so. - `experimental.useTypeScriptCli: true` is now pinned. TypeScript 7 ships no JavaScript compiler API until 7.1, so Next's default checker cannot run and needs the project-local `tsc` CLI instead. 16.2.12 was silently skipping build-time type checking entirely because it detected @typescript/native-preview and short-circuited the stage ("Finished TypeScript in 138ms"); pinning the flag keeps that from drifting back. TypeScript toolchain cleanup that the upgrade makes possible: - Drop @typescript/native-preview from apps/sim and apps/docs. It was the pre-release channel for TS 7 and is superseded by typescript@7 (nightlies now ship as typescript@next), and its presence is what suppressed build type checks. - Align packages/browser-protocol and packages/terminal-protocol from typescript ^5.7.3 to ^7.0.2 so every workspace is on one compiler version. apps/sim keeps @typescript/typescript6 as a production dependency: the function sandbox at app/api/function/execute dynamically imports the TS 6 compiler API to transpile user code, and TS 7 has no API to replace it yet. Build and dev were benchmarked 3x per version on a byte-identical tree; the upgrade is performance-neutral (build median 100s -> 99s, dev:full warm 10s -> 9s). |

Skipped as moot (dev already did them independently): launcher isVisible removal, decideStartRoute param drop, local-filesystem clear() removal. * chore(desktop): biome format install-local.ts (pre-existing dev lint failure) * refactor: apply audit cleanup (reuse + simplify) - domain-check: drop the redundant isIpLiteral guard (isLoopbackIp already validates and returns false for non-literals). - session.ts: use shared getErrorMessage instead of the local error ternary (the file already imports it). - tray.ts: use shared sleep() instead of a hand-rolled setTimeout promise. - updater.ts: distinguish the synchronous-throw log from the async-rejection log on the manual update check. * refactor: /simplify pass + review fixes - url-guard: bound the SSRF dns.lookup with a 5s deadline (fails closed on timeout) so a slow/hung resolver can't suspend the check and the onBeforeRequest callback indefinitely (Greptile P2); + test. - Finish the reuse consolidation the earlier pass missed: session.ts second error ternary → getErrorMessage; the bracket-strip idiom → unwrapIpv6Brackets in input-validation.ts, input-validation.server.ts (×2), onepassword/utils.ts (fixes the check:utils banned-pattern CI failure). - driver: document why the tool-level checkAgentUrl coexists with the onBeforeRequest enforcement seam (clean model error; loadURL rejection is swallowed). * fix(desktop): swallow late DNS rejection after the SSRF lookup timeout (Cursor) * refactor: split pure host helpers into @sim/security/hostnames (ipaddr-free) (#5787) unwrapIpv6Brackets + isLoopbackHostname move to a new ipaddr-free sub-export so client code can share them without pulling ipaddr.js into the browser bundle. ssrf.ts re-exports both, so its server/desktop consumers are unchanged. This eliminates the duplicate isLoopbackHostname in apps/sim/lib/core/utils/urls.ts: urls.ts and its three client importers (mcp queries, oauth probe, oauth url-validation) now use the single shared definition. * Desktop app fullscreen mode * fix(copilot): report closed browser session as a distinct terminal tool error A dead agent browser session used to answer every browser tool with an indistinguishable generic ~30s IPC timeout, which the model retried indefinitely (one turn: 59 minutes of failing browser_snapshot calls). - When the desktop app has reported the session closed, page-dependent browser tools fail immediately with an explicit session-closed message (and sessionClosed: true in the result data) instead of burning the full timeout per call. browser_navigate / browser_open_tab / browser_list_tabs still run, since they can start a new session. - A failure whose session died mid-call (e.g. during a takeover) gets the same tag appended, so the model learns the terminal cause rather than seeing a plain timeout. Companion to mothership's tool_failure_loop circuit breaker. * fix(desktop): route Cmd+W to focused browser tabs * fix(desktop): reserve macOS title bar safe area * fix(desktop): limit title bar safe area to login * fix install script * feat(desktop): improve local folder settings * feat(desktop): harden local capabilities and window chrome * fix(invitations): live refetches * fix(desktop): make manual update checks use updater state * fix(desktop): review fixes — OAuth error handling, query freshness, invitations Findings from an end-to-end review of the desktop work, fixed and verified. OAuth connect/login handoff: - Add a friendly /oauth-error landing page + onAPIError.errorURL so provider Cancel/Deny (which Better Auth redirects before the flow state is parsed) no longer dead-ends on a 404; re-initiating supersedes the idle loopback. - Stop a post-consent failure from reporting success (drop the baked-in errorCallbackURL param that collided with Better Auth's appended code; coerce an array error defensively on the complete page). - Guard the desktop connect listener with the same context-age check the web routers use, so an abandoned flow can't mislabel a later completion. - Clear an orphaned pending handoff when a loopback re-bind fails. Query freshness (desktop refetchOnWindowFocus): - Pin refetchOnWindowFocus off on queries that seed editable forms (environment/secrets, credential detail, schedules) so a background focus refetch can't drop an unsaved draft, and on the useWorkflowStates fan-out so returning to a large table doesn't fire N heavy envelope fetches. All no-ops on web (default already false). Invitations (in-app pending invitations): - Map accept/decline failures to friendly copy instead of raw machine codes. - Invalidate subscription + refresh session on accept (parity with the email path); reconcile the list on failure (onSettled) so dead rows drop. - Gate the modal's query on open so it no longer fetches on every app load. CI: - Wrap the latest-mac.yml update-feed route in withRouteHandler and allowlist it as a non-boundary route (input-less, YAML) so the contract audit passes.

The row now shows a plain 14px folder icon and the folder name alone. Clicking a row reveals the folder in the OS file manager through a new reveal_mount bridge op, which resolves the opaque localfs URI to a live grant and requires an active user gesture, matching the other grant mutations. The absolute host path still never crosses the bridge.

The version value moves off text-caption onto text-sm — it was rendering at the subtitle size, which also shrank the "x -> y on restart" line that matters most.

The embedded browser is still a single native surface, so exactly one window owns it at a time. Ownership transfers only to the focused window: without that rule, two windows both showing the browser reclaim it on every bounds heartbeat and re-parent the native view back and forth roughly once a second while Sim sits in the background, where no window is focused. A destroyed owner is now forgotten rather than left rejecting updates from the window actually on screen, and a closing window's release is honoured even though Electron destroys it before emitting `closed` — previously that release was dropped and the next layout could re-parent the browser onto a window that never asked for it. The agent's password boundary is now enforced rather than assumed. It was treated as settled but had four ways through: `browser_press_key` sent trusted CDP keystrokes to whatever held focus, `clickElement` focused credential fields, `readActiveElementState` returned a preview of any focused value, and snapshots printed the contents of revealed password fields. Detection also used `instanceof HTMLInputElement`, which is realm-bound and returned false for inputs inside same-origin iframes — the nested login forms that need it most. Detection now matches on tagName/type/autocomplete, the keystroke guard runs in the driver where trusted CDP input is visible, and typing re-checks the real target before inserting, since login forms advance focus between the username and password steps. Signing out clears the embedded browser's profile. Its cookies, cache, pinned tabs, browsing trail, and reopen list all survived sign-out, so the next account on the machine inherited the previous user's live sessions. Partition hardening is keyed per session instead of a process-wide flag, which would have left a second partition with no permission handlers, no SSRF filtering, and no download blocking — silently, and still type-checking. Adds the first tests for page-functions.ts, including a serialization contract check: those functions ship to the page as String(fn), so a reference to module scope passes every other test and fails only against a real page. * fix(desktop): close clipboard, glob DoS, and authorization holes Found by a full audit of the desktop app against origin/staging. Each of these was measured or asserted rather than reasoned about. The agent could read the user's system clipboard. `browser_press_key('Cmd+V')` pasted it into a focused field and the next `browser_snapshot` returned it as an ordinary `value` — snapshots redact password fields, not pasted content, and clipboards routinely hold a password copied out of a manager. The credential guard added earlier did not catch it: `insertedTextFor` returns undefined whenever `meta` is set, so `Cmd+V` was classified as not text-inserting. `Control+V` reached the same place because the macOS normalizer rewrites it. Clipboard combos are now refused before dispatch rather than by withholding the CDP `commands` array, since off macOS these are Blink-native and a key event alone still performs them. Copy and cut go too — they clobber the user's clipboard as a side effect. A glob pattern could freeze the whole app. Micromatch compiles to a backtracking regex whose cost is exponential in wildcard count: measured against a single 46-character path with the options this code passes, ten wildcards took 2.7s and twelve took 43s, once per scanned entry, in one synchronous call that the surrounding abort checks never get to interrupt. That is the main process, so every window, the menu bar and the tray freeze with Force Quit as the only recourse, and the pattern is model-supplied. `safeRegex` reports the generated source as safe, so it was no defense. Patterns are now bounded at six wildcards, which keeps the worst case near 2ms while leaving headroom over real patterns (which top out around four). A timing probe backs it up, with a budget loose enough that JIT warmth and machine load cannot make it fire on a legitimate pattern — a tight budget proved flaky in both directions. The grep authorization guard compared `request.pattern !== args.pattern`, so a tool call carrying no pattern made that `undefined !== undefined` and the guard passed — grep then fell back to searching the renderer's own `query` across the whole grant. `include` and `query` were never bound at all, letting a renderer widen a search or silently narrow results the agent believes are complete. The sibling glob case already had the `typeof` check, which is what made the asymmetry clearly unintentional. The IPC sender gate used `startsWith`, the exact pattern `isAppOrigin` warns against 200 lines away ("that prefix-matches lookalike hosts"). It was safe only because of a trailing slash. It now uses that helper, which also fixes a false negative on an explicitly stated default port. * fix(desktop): stop double sign-out, stranded retries, and redundant writes Three correctness bugs from the same audit. Menu Sign Out tore down the session directly instead of going through the lifecycle coordinator, so it skipped the in-progress guard — and its own cookie removal then tripped the coordinator's cookie watcher into a second concurrent teardown, duplicating the sign_out event, the storage clear, and the /login load. Teardown also existed as two divergent copies. The coordinator now exposes `signOut()` and owns the single path; the menu just calls it. That `tearDownSession` is no longer imported in index.ts is the check that it landed. Offline recovery could strand permanently. The auto-retry loop stops itself before calling `retry()`, and `retry()` never re-armed the load watchdog, which is started once per window. So if a retried load hung — precisely what the watchdog is for — no load event fired and no timer remained anywhere; the user sat on the offline page until the window was closed. `retry()` now re-arms before loading. Pinned tabs were persisted on `did-navigate` and `did-navigate-in-page` for every tab, pinned or not, with no change check, and the settings store compares with `===` so a freshly built array never matched. Any single-page app therefore triggered a synchronous mkdir + write + rename of the whole settings file on the main thread on every route change — writing `[]` over `[]` when nothing was pinned. The list is now fingerprinted, seeded at restore from what is already on disk so the first navigation after launch is not a write either. * fix(desktop): leaked timers, silent grep failures, and crashed tabs Second pass on the audit backlog, all verified against tests that fail without the change. Every browser tool call leaked a timer. The watchdog raced the tool against `sleep()`, which cannot be cancelled, so when the tool won — the normal case — the timer stayed pending for the full window, up to two minutes, dozens deep during an agent run. Replaced with a cancellable timeout cleared in a `finally`; a test asserts the fake-timer count is unchanged across a call. An invalid grep regex reported "no matches". A SyntaxError from `new RegExp` returned an empty result set, which tells the model the string appears nowhere in the user's files — a factual claim it acts on, when the search never ran. It now fails as INVALID_REQUEST. The `safeRegex` guard moved out of the try while there, since it was only inside it to be re-thrown. A crashed tab wedged the session. Tabs left `tabs` only via close, so a dead renderer stayed forever: `activeTab()` filtered it out while `activeTabId` still named it, making `requireTab()` report "no page is open" with other tabs open, and the panel went blank with no recovery. `render-process-gone` now drops the tab, advances the active id, and reports session closure when it was the last. `probeSession` cleared its abort timer inline after the await, so a thrown fetch — the case the function exists for — skipped it. Moved to `finally`, which also brings the body read inside the deadline. One vanished file failed a whole directory listing: `Promise.all` over per-entry `lstat` turned a single ENOENT into NOT_FOUND for the directory. Churning directories like build output would intermittently fail to list. Removed the `session-lifecycle -> browser-agent/driver` import edge, which dragged the entire browser subsystem and its module-load `nativeTheme` listener into the auth path to reach one four-line function. `clearBrowserProfile` is now a required dependency wired from index.ts, which already owns both sides. Also deleted `attachSessionLifecycle`, a compatibility wrapper with zero callers. Added a channel-parity test between the preload bridge and the IPC table. They share ~20 channel names as bare string literals with nothing tying them together, so a typo on either side is a silently dead feature that type-checks and ships. Verified it fails on a one-character change. * fix(desktop): reach framed elements and harden the loopback sign-in Two behaviour fixes from the audit backlog. Interaction with same-origin iframes was broken. The snapshot deliberately walks into those frames and hands the model ids for what it finds, but every interaction then tested `instanceof HTMLInputElement` against the top frame's constructors — false for nodes owned by a frame, because element wrappers are realm-bound. So the driver reported a real `<input>` as "not a text input", which took out framed login forms and editors that put a contenteditable body in an iframe, such as TinyMCE. Framed selects reported "not a select" and framed clicks skipped focus entirely. Checks now compare `tagName` or duck-type the method being called, matching the realm-safe approach the credential guard already used. The native value setter is taken from the element's own realm: calling the top frame's setter on a frame's node throws "Illegal invocation". Snapshot value reporting follows the same rule, which is safe because the credential redaction above it is realm-safe and runs first. The loopback sign-in server could be cancelled by anything on the machine. It validated only the shape of the returned state, then tore the one-shot server down and dispatched, leaving the real constant-time comparison to the callback. So a request carrying any well-formed state killed an in-flight sign-in — and the port is reachable by any local process and by any page the user has open via a no-CORS GET, which cannot read the response but does not need to, since the side effect is the kill. The state is now checked before anything is torn down, and a Host that does not name the loopback is refused, which closes the DNS-rebinding shape. * refactor(desktop): drop duplicated helpers and stop logging query strings Net -3 lines, and one of them was a real leak. `navigation.ts` and `windows.ts` truncated URLs for their log lines with a bare `.slice(0, 200)`, which keeps the query string — the five other log sites in the app go through `scrubUrl` for exactly that reason. Tokens and signed parameters live in query strings, so a blocked-URL warning could write one to disk. Both now scrub. `local-filesystem.ts` carried a private `isRecord` byte-identical to `isRecordLike` in `@sim/utils/object`, and four more sites inlined the same check. All now use the shared helper, which also tightens three of them: the inline versions omitted the array exclusion, so an array satisfied a check that then cast it to a record. `tray.ts` hand-rolled slice-plus-ellipsis, the case `@sim/utils/string`'s `truncate` exists for. Titles between 58 and 60 characters now get an ellipsis where they previously did not — cosmetic, in a tray menu label. Removed the `getTabsState` passthrough in the driver, a one-line re-export of the session's own function, and renamed the session-level clear to `clearProfileStorage`. `clearBrowserProfile` existed twice under one name, the driver's being the composite that also clears the browsing-trail registry; index.ts was already aliasing at the import to tell them apart. Two things deliberately not done. The hand-rolled semver in updater.ts stays: replacing it needs `semver` plus `@types/semver` as new declared dependencies in the Electron main process, and the 90 lines it would delete are already covered by eight assertions that I verified match the library's behaviour case for case. Note the same prerelease comparison is duplicated in apps/sim/lib/desktop/min-version.ts, so a future consolidation should do both. No barrel for browser-agent either: routing `security-guards.ts` through one to reach a single leaf function would pull the whole browser subsystem into its module graph, which is the edge just removed from session-lifecycle. * refactor(desktop): move browser compositing out of the session module session.ts held five responsibilities in one flat namespace: 1,061 lines, 29 exports, 26 mutable module-level bindings. For contrast local-filesystem.ts is a comparable 1,125 lines with two exports and no ambient state — size was never the problem, the shared mutable namespace was. Compositing is the part worth isolating. Where the native view sits, when it is visible, which window owns it, the renderer bounds lease, and the occlusion snapshot are the most intricate logic in the browser and are almost entirely separable from tab bookkeeping. They now live in panel.ts (342 lines) and session.ts is 792, with 15 bindings instead of 26. The two modules were mutually dependent, which is what makes this kind of split go wrong. Rather than events or a shared store, panel.ts takes the four things it needs from the session through one PanelHost passed to initPanel — the same shape as the existing initSession — so the import graph is one-way and there is no new indirection to trace. Tab changes reach the panel by the session calling layout(), exactly as before. Two behaviours became explicit rather than implicit in the move: detachIfAttached replaces callers reading `attachedView` to decide whether a closing tab owns the surface, and isPanelVisible replaces `panelBounds !== null`. Nothing about the split is verified by the split itself, so the bounds lease got characterization tests first. It had none — there was not a single fake timer in the suite — despite being the mechanism that hides the view when the renderer crashes or wedges. Both tests were confirmed to fail against a broken lease before the refactor began. The other 47 tests were not rewritten: only the module their calls address changed, which is the useful signal that behaviour was preserved. Deliberately not split further. Focus tracking stays with tabs because it keys off tab ids, and profile teardown stays put; separating either would be taxonomy rather than decoupling. * refactor: drop the legacy local_* filesystem tool shim Granted folders are addressed through the ordinary VFS: the model calls read/grep/glob against paths under user-local/, exactly as it does for workspace files. A parallel local_read / local_grep / local_glob / local_list / local_stat / local_mount_directory / local_list_mounts / local_forget_mount / local_stage_file toolset existed alongside it, recognized but never advertised, so an in-flight checkpoint written by an older desktop build could still finish. There are no older desktop builds. apps/desktop is at version 0.0.0, the only artifacts are a local 0.0.0 build, MIN_DESKTOP_VERSION is '0.0.0' meaning no floor, and the app does not exist on staging at all — the v0.7.x tags are the web app's. Nothing can have persisted a checkpoint naming these tools, and nothing advertises them: they are absent from the generated tool catalog and from mothership's catalog. The shim was defending against a past that never happened. Removes the name table, the legacy request builder, the server-side LEGACY_READ_ONLY_TOOLS allowlist, the five local_* branches in the desktop authorization switch, and nine display labels. isDesktopFilesystemToolCall collapsed into isUserLocalVfsToolCall, which it had become a synonym for. Two tests went with it. One asserted that local_list_mounts routes to the desktop; the test immediately after it already covers the real path, an ordinary read against a user-local path. The other asserted that legacy names cannot open a folder picker, revoke a grant, or upload bytes — that property now holds because no such tool name exists, which is a stronger guarantee than refusing one. * refactor(copilot): remove the plan/changelog VFS artifacts and workflow aliases These beta surfaces are not a direction we are taking, so they come out rather than staying behind a flag. Gone: the workflow alias modules (path resolution, DB-backed resolver, .plans/.changelogs backing provisioning), the alias materialization in the copilot VFS, the alias write paths in resource-writer and workspace_file, the sandbox alias mounts in function_execute, the reserved backing-path guards across mkdir/mv/create, and the alias resolution in the chat home file picker. xlsx survives but changes owner. It was gated twice across the repo boundary: mothership's xlsx-writing flag gates the skill and prompt, while Sim gated the compile path on mothership-beta. Those live in separate AppConfig applications, so an operator had to flip two flags in two consoles, and off-hosted Sim fell back to the MOTHERSHIP_BETA_FEATURES secret while the mothership half stayed in Sim Cloud's AppConfig — split-brain across an ownership boundary. Mothership controls whether the model ever learns xlsx exists, so if it is never offered it is never requested and the second chokepoint only created a way for the two halves to disagree. Sim's gate is removed; xlsx-writing is now the single owner. With its last consumer gone, the mothership-beta flag and the MOTHERSHIP_BETA_FEATURES secret are deleted. The two entries in the infra repo are harmless until removed separately: they only inject an env var nothing reads, and createEnv runs with skipValidation. The reserved-system-file/folder concept goes with the aliases, since it existed only to hide the backing rows. includeReservedSystemFiles and includeReservedSystemFolders are removed rather than left as options every caller passes true to. backingVfsPath is removed for the same reason — nothing sets it once aliases are gone, so it was an always-undefined field on tool results. Test coverage is preserved rather than deleted with the feature. resource-writer.test.ts looked alias-only but three of its eleven cases cover the generic create path that survives; those are kept and the file retitled. Two open_resource tests and one output-path test used alias-shaped strings while asserting generic behavior; retargeted or dropped where a sibling already covers it. * refactor(copilot): remove the dead planArtifact column plumbing copilot_chats.plan_artifact has no writer and no reader that does anything with it. No client sends it, nothing renders it, and its whole history is fork-chat and duplicate-chat plumbing faithfully copying a column that is always null — the one change that might have populated it (mothership v0.8) was reverted. Removed from the schema, the copilot API contract, the chat lifecycle column sets, the fork route, superuser import, the data drain, the update-messages write path, and the legacy chat detail response. No migration here on purpose. The column stays in the database, orphaned and null; dropping it is a separate deliberate step rather than something that rides along with a code cleanup. Note that the next drizzle-kit generate will now want to emit the DROP COLUMN, and check-migrations-safety will ask for it to be annotated — that is the right moment to decide, not now. Mothership never saw this field; it is Sim-side only. * chore(copilot): sync the tool catalog for load_skill Picks up the new load_skill tool plus the grep description that dropped its stale reference to VFS "plans" entries. Generated from copilot/contracts/tool-catalog-v1.json. * refactor(copilot): follow the load_custom_tool rename to load_mcp_tool Mothership renamed the loader once it was clear MCP was the only catalog kind it could match, and dropped the single-valued `type` parameter. The two prompt strings that teach the model the call shape are updated to load_mcp_tool({ name }). load_custom_tool stays in the UI hide-list next to load_agent_skill so tool rows in historical transcripts keep rendering; nothing emits it any more. * chore(copilot): sync the tool catalog and hide load_skill in the UI load_integration_tool and list_integration_tools now publish route go/sync instead of sim/async. Nothing changes in Sim's behavior — they always ran in Go; the contract had been wrong. load_skill joins the hidden tools. It is the same shape as the other loaders already there: the agent pulling in a reference guide before doing the work is a step toward the action, not the action. Sim's display-coverage test caught that a newly added visible tool had no title or completed verb, which is the guard working. * fix(auth): handle session expiry in the app, not the desktop shell The workspace auth gate is a Server Component, so it only re-evaluates on a server render. A session that expired or was revoked mid-visit left the SPA mounted and silently 401ing every request, with nothing to redirect it. The desktop shell had grown its own detector for this: a 401 listener over /api/*, a session probe, and a native "your session has expired" prompt. It could only infer session state from cookie events and HTTP statuses, and it inferred wrong — it fired on ordinary sign-outs (in-flight requests 401 during teardown) and on launching already signed out (the window still shows the restored route while the web app redirects). Those were nearly all of its firings, since a 30-day sliding window means real expiry is rare. Generalizes the impersonation-expired screen instead, which already had the right shape: it keys off the session query settling to null after a session that was live. A signed-out visitor never arms it, and `error` is excluded so an offline blip cannot read as an expiry. The session query now refetches on focus for every session, not just impersonation ones, so returning to a window that slept through its session re-checks it.

Also clamps browser_wait_for's timeout the way the desktop agent does, and replaces the oversized-read error's offset/limit advice, which sent the model into a guaranteed retry loop. * feat(desktop): let the model actually see browser screenshots browser_screenshot captured an image and then threw it away. The renderer stripped the data URL and substituted a note, and the tool's own description told the model not to bother: "Dead end for perception." So the agent was blind to anything not expressible as DOM text — canvas, charts, maps, images, rendering and layout bugs. The copilot has carried the machinery for this all along. A tool result shaped as { content, attachment: { type: "image", source: { type: "base64", ... } } } is serialized into a real image content block, with the media type sniffed from the bytes rather than trusted from the declaration, and degraded to a text stub when the routed model has no vision so the provider never 400s. The screenshot result is now reshaped into that contract instead of discarded. A malformed data URL still falls back to a note rather than shipping an attachment the provider would reject. Captures are bounded to a 1024px longest edge at quality 70. CDP clip.scale is relative to CSS pixels, so this also sidesteps the device pixel ratio — an unclipped capture on a retina display returns a 2x image, which was several hundred kilobytes for no legibility the model could use. The description is rewritten to bias toward visual questions only: appearance, layout, rendering, charts, canvas. Reading content or finding something to click stays with browser_snapshot, which is cheaper and returns the element ids a screenshot cannot. That distinction is structural, not just advisory — having seen the page does not let the agent act on it. Companion change in mothership generalizes the tool-result inline-budget exemption from "the read tool" to "any result carrying a model attachment". Keyed on the tool name, an oversized screenshot fell through to the artifact branch: the image was replaced by a reference the model cannot open, and the result still reported success. Silent, and it would have hit almost every call. * fix(desktop): polish browser panel and environment tray icon * fix(desktop): enlarge environment tray markers * fix(desktop): smooth environment tray markers * refactor(copilot): consolidate resource mutation tools * chore(copilot): clean up VFS follow-ups * fix(desktop): round the dev tray marker * feat(desktop): add integrated terminal resources * Fix electron app resize causing glitchy browser frames * feat(copilot): add persistent tool permissions * fix(copilot): retire stale tool permission prompts * fix(desktop): keep terminal rendering responsive * fix(desktop): preserve resource rendering continuity * feat(desktop): add browser tab duplication actions * feat(desktop): add terminal tab context actions * fix(desktop): allow browser agent localhost navigation * feat(desktop): add tmux-backed terminal sessions * fix(desktop): restore terminal scrollback per view * chore(copilot): sync updated wait tool contract * poll terminal session state for non regular shells * add terminal right click menu * feat(desktop): add terminal handoff and key batching * fix(desktop): reserve the traffic-light lane from the platform macOS draws the window controls itself, at a fixed physical size, above all web content. The page renders full-bleed beneath them, so it has to reserve that lane — and it did so with five hardcoded CSS pixel values. CSS pixels scale with page zoom and the OS-drawn lights do not, so zooming out shrank the reservation until the lights were drawn over the sidebar toggle, and the header row below sat inside their band. Electron's `titleBarOverlay` publishes the controls' real geometry to the page as the `titlebar-area-*` env vars, which Chromium rescales per zoom so a reservation derived from them holds its physical size. Measured across zoom 0.58-1.2, the reserved area stays within ~0.6 DIP, the residual coming from env values being quantized to whole CSS pixels. Every lane length now derives from those vars, so the login route and the mothership content offset were fixed without being touched — they already read `--desktop-title-bar-height`. Two of the replaced constants were also simply wrong: the platform reports the lane at 38px and the safe area at 81px, against the hand-measured 36 and 83. The toggle keeps a constant physical size beside the lights, expressed as a proportion of the lane rather than in pixels: a px literal would scale with zoom, and calc cannot divide a length by a length to recover a scale factor.

Co-Authored-By: Claude <noreply@anthropic.com> * feat(db): regenerate copilot tool-permission migration on top of staging Replaces the branch's old 0264/0265 (dropped pre-merge so staging's 0264-0270 chain could apply cleanly) with a single 0271 generated against staging's schema: the permission-decision enum, the two copilot_async_tool_calls decision columns, and copilot_chats.auto_allowed_tools. Deliberately does NOT drop copilot_chats.plan_artifact. The branch removed every reader, but the currently-deployed code still SELECTs that column, so dropping it in the same deploy breaks the old app version during blue/green overlap — `check:migrations` flags it for exactly this reason, and the honest fix is to defer rather than annotate around it. The column is retained in schema.ts marked @deprecated; drop it in a follow-up once this has rolled out. Also in this commit, all fallout from the merge itself: - pinned-fetch/revoke tests: their private-IP stub moved to @sim/security/ssrf alongside the source change. Worth noting the stub exists because the suite's 203.0.113.10 is TEST-NET-3, which the real classifier correctly calls reserved — the old stub had been quietly disagreeing with production. - materialize-file test: dropped the reserved-system-folder case, which covered the workflow-alias backing folders this branch deleted. - api-validation route ratchet 977 -> 983 (this branch's new routes). Co-Authored-By: Claude <noreply@anthropic.com> * add cmd f * review pass * chore(db): drop branch migration ahead of staging merge Both sides independently claimed idx 0271, so the snapshot and journal would conflict add/add. Ours is plain additive DDL that drizzle regenerates from schema.ts; staging's is a hand-written CONCURRENTLY index build that cannot be regenerated. Dropping ours and re-generating on top of staging's is the only order that preserves both. schema.ts is deliberately untouched — it is the source of the regeneration. Co-Authored-By: Claude <noreply@anthropic.com> * chore(db): drop branch migration ahead of staging merge Both sides independently claimed idx 0272, so the snapshot and journal would conflict add/add. Ours is plain additive DDL (one enum, two columns, one jsonb default) that drizzle regenerates from schema.ts; staging's is a hand-written migration with DO blocks and CONCURRENTLY index builds that cannot be regenerated. Dropping ours and re-generating on top of staging's is the only order that preserves both. schema.ts is deliberately untouched — it is the source of the regeneration. Co-Authored-By: Claude <noreply@anthropic.com> * style(db): biome-format the regenerated migration metadata drizzle-kit emits _journal.json and the snapshot with expanded arrays, which biome check rejects. The merge commit used --no-verify, so lint-staged never formatted them and CI's lint step failed on exactly these two files. Whitespace only — both files are byte-identical under `jq -S -c`.

The suite mocked electron's systemPreferences but inherited the runner's real platform, so the eight biometric expectations passed on a Mac and failed on Linux CI, where every call fell through to the confirmation dialog instead. Pins the platform per-test and restores it after, and adds a case for the gate itself — the branch whose absence from the suite is what let this through.
