Do not build streamUrl from the Host request header.
req.get('host') returns the client-supplied Host header. When MAXUN_BROWSER_STREAM_URL is unset, the response tells the caller to open a WebSocket against that host. An attacker who can reach this endpoint sets Host to a server they control, and the caller connects there with its stream or control capability token.
The same construction appears at Line 517 in the stream-capability route.
Derive the URL from trusted configuration only, and fail closed when it is absent.

A second stream socket silently takes over the stream from the first.
updateStreamSocket assigns this.socket = socket. The rrweb bridge at Line 488 emits every event with this.socket.emit('rrweb-event', event). RemoteBrowser holds one socket reference, so the last stream socket to attach receives all events and every earlier stream viewer stops receiving DOM updates with no error.
server/src/browser-management/controller.ts:495 routes each additional stream-capability socket through this method, so this happens whenever two stream capabilities are redeemed for the same browser.
If concurrent stream viewers are supported, emit rrweb events to the namespace instead of to a single socket. If only one viewer is supported, disconnect the previous stream socket here so the takeover is explicit.

The selector field is taken from the client, not owned by the server.
RemoteBrowserControlCommand.selector in server/src/browser-management/classes/RemoteBrowser.ts:59-60 is documented as a "Server-owned selector used only for an explicit recorded key action". This line copies it straight from the request body with String(source.selector).
executeControlCommand then passes that value to this.generator.onDOMKeyboardAction, which writes it into the generated workflow. A caller therefore controls a selector that is persisted in a robot definition and executed on later runs. The stated invariant does not hold.
Either derive the selector on the server from the click or focus target, or validate it against the elements the server already discovered. If the client-supplied value is intended, correct the comment in RemoteBrowser.ts so the trust boundary is documented accurately.

acquireControl leaks a raw UniqueConstraintError when two sessions create the first lease concurrently.
SELECT ... FOR UPDATE at Lines 103-107 locks an existing row. It does not block a concurrent insert of a row that does not exist yet. Two concurrent acquireControl calls for the same (userId, browserSessionId) can both reach the ControlLease.create at Line 140. One insert then violates maxun_control_lease_browser_unique from 20260819010000-create-maxun-control-leases.js.
The rejection is not a ControlLeaseError, so callers that branch on error instanceof ControlLeaseError (for example attachControlSocket in server/src/browser-management/controller.ts) fall through to a generic internal error instead of control_conflict. claimResource in server/src/sdk/resourceClaims.ts already handles this same race for claims; apply the same treatment here.

Bind observation acknowledgement to a fresh snapshot.
This endpoint sets observationReady after only lease and epoch validation. It does not require evidence that rrweb emitted a snapshot after the current control epoch. An agent can acknowledge immediately after takeover and issue commands without a fresh observation.
Track a server-generated snapshot version or nonce per control epoch. Accept acknowledgement only for a snapshot emitted after that takeover.

Initialize agent leases as observation-required.
requireControlLease blocks agent browser actions only when observationReady is false. These defaults and the initial create path mark an agent lease ready before an acknowledgement occurs. A new agent lease, or an active agent lease during migration, can issue browser actions without a fresh observation.

Do not use sequelize.sync() as the migration baseline.
sequelize.sync() creates the current model schema before Sequelize records the migration history. The conditional up handlers then skip schema creation but are still recorded as applied. A later migration rollback can delete a table or column that schema preparation created, which can delete data or leave the model schema incompatible with the database. Use a versioned baseline schema, or ensure that migrations own all resources that their down handlers remove.

Preserve the robot-name conflict invariant.
This path updates the linked robot name directly. If robotName already belongs to a different robot for the user, this creates two logical robots with the same name. persistNativeRobot detects this case, but this path bypasses that check.
Before renaming the linked robot, resolve and lock a distinct same-name robot. Then reject the conflict or replace and relink it according to the intended duplicate policy.

Do not use the upgrade time as the last access time.
lastAccessed is set when the slot becomes ready, but this file does not refresh it during later browser use. After three minutes, cleanupStaleBrowserSlots() classifies every ready run slot as leaked and calls failBrowserSlot(). A valid run that remains active longer than three minutes can therefore be closed while the worker still uses it. The new cleanup call in reserveBrowserSlotAtomic() also activates this deletion path during capacity checks.
Track browser activity with a server-side touch/heartbeat or an explicit run/control lease. Reclaim a slot only when the server has confirmed that it is idle. Add a test that keeps a ready run active beyond the threshold and verifies that cleanup preserves it.
Evidence: server/src/server.ts Lines [181]-[227] schedules cleanup every 60 seconds, and server/src/browser-management/controller.ts Lines [467]-[643] uses the browser after upgradeBrowserSlot().
