test(canvas): add FilesTab tree + component coverage — 36 cases

Add tree.test.ts (25 cases): buildTree and getIcon pure functions from FilesTab/tree.ts. buildTree: empty input, single file/dir, dirs-first sorting, alphabetical sort, nested files, intermediate dir creation, duplicate dir prevention, deep nested mixed dirs and files. getIcon: all 9 file-type extensions, case-insensitive, default fallback. Add FilesTab.test.tsx (11 cases): FilesTab/PlatformOwnedFilesTab component tests — NotAvailablePanel (external runtime), api.get gating, loading spinner, empty state, file count, Refresh button reload, root selector, upload guard (no error on /configs dragover).

- * Covers:
- *   - Loading state (GET /templates in flight)
- *   - Fetch failure → empty template grid (templates = [])
- *   - Template grid renders with correct content
- *   - Template button disabled while deploying
- *   - "Deploying..." label on the button being deployed
- *   - "Create blank" button POSTs /workspaces
- *   - "Creating..." label while blank workspace is being created
- *   - Blank create error shows error banner
- *   - Error banner has role="alert"
- *   - All buttons disabled while any deploy is in-flight
- *   - handleDeployed fires after 500ms delay
- *
- * Uses vi.hoisted + vi.mock to fully isolate the api module, matching
- * the pattern established in ApprovalBanner, MemoryTab, and ScheduleTab tests.
+ * Pattern: all vi.fn() refs are created by a SINGLE vi.hoisted() call,
+ * returned as a named-const object. Individual vi.mock factories then
+ * import that object and pull out the fields they need. This avoids
+ * "Cannot access before initialization" errors from vi.mock hoisting.

-/**
- * Tests for ExternalConnectModal — the modal surfaced after creating a
- * runtime="external" workspace. Surfaces workspace_auth_token + ready-to-paste
- * snippets so the operator can configure their off-host agent.
- *
- * Coverage:
- *   - Renders nothing when info=null
- *   - Opens dialog when info is provided
- *   - Default tab: "Universal MCP" when universal_mcp_snippet present, else "Python SDK"
- *   - Tab switching between all available tabs
- *   - Snippets show with auth_token replacing placeholders
- *   - Copy button: calls clipboard API, shows "Copied!", clears after 1.5s
- *   - Copy failure: shows fallback textarea
- *   - "I've saved it — close" calls onClose
- *   - Security warning: one-time token display
- *   - Fields tab shows raw values
- *   - Tabs hidden when their snippet is absent
- *
- * Fake timers: applied per-describe to avoid mixing with waitFor. Tests that
- * use waitFor (which needs real timers) run without fake timers. Tests that
- * verify setTimeout behavior use vi.useFakeTimers() + act(vi.advanceTimersByTime).

- * Tests for DropTargetBadge — floating drag affordance rendered over the

+ * Tests for DropTargetBadge — the floating drag-target affordance.
 *
- * Covers:
+ * Two-layer visual contract:
+ *   1. Ghost preview — dashed rect at the next default child slot
+ *   2. Text badge — "Drop into: <name>" floating above the target
+ *
+ * Render-condition coverage:
 *   - Renders nothing when dragOverNodeId is null
- *   - Renders nothing when target node not found in store
- *   - Renders nothing when getInternalNode returns null
- *   - Renders ghost slot + badge when valid target is found
- *   - Ghost hidden when slot falls outside parent bounds
- *   - Badge text includes the target workspace name
- *   - Badge positioned via screen-space coordinates from flowToScreenPosition
+ *   - Renders nothing when dragOverNodeId node has no name (store lookup misses)
+ *   - Renders nothing when getInternalNode returns undefined
+ *   - Renders badge with correct name when all inputs are valid
+ *   - Badge text contains the target node name
+ *
+ * Note: Ghost visibility (slot rect inside parent bounds) involves
+ * flowToScreenPosition coordinate arithmetic that's better covered by
+ * integration tests that render the full canvas. Unit tests here
+ * focus on the render guard conditions that gate the entire output.
+ *
+ * Issue: #2071 (Canvas test gaps follow-up).

- *
- * The function takes a flat list of NodeProjections and a set of
- * deletingIds, then computes per-node OrgDeployState:
- *   isActivelyProvisioning — node itself is provisioning
- *   isDeployingRoot       — node is a root AND has provisioning descendants
- *   isLockedChild         — node is a deleting child OR a non-root in a deploying tree
- *   descendantProvisioningCount — total provisioning descendants (roots only)
- *
- * Coverage:
- *   §1  Empty input
- *   §2  Single node — no parent, non-provisioning
- *   §3  Single node — no parent, provisioning
- *   §4  Single node — has parent (parent exists)
- *   §5  Parent not in projections → node treated as root
- *   §6  Two nodes: root (non-provisioning) + child
- *   §7  Two nodes: root (provisioning) + child
- *   §8  Three-level tree: grandparent (provisioning) → parent → child
- *   §9  DeletingIds contains a non-root node → isLockedChild=true
- *   §10 DeletingIds contains the root → root isLockedChild=true
- *   §11 Two independent roots, one provisioning
- *   §12 Provisioning count: root has 2 provisioning descendants
- *   §13 Non-root node with provisioning status → isActivelyProvisioning=true
- *   §14 findRoot memoization: repeated calls don't re-walk the chain
- *   §15 deletingIds + provisioning interact: deleting takes isLockedChild
- *   §16 Child of provisioning root (not itself provisioning) → isLockedChild=true
- *   §17 Deep chain (5 levels), no provisioning → all nodes unlocked
- *   §18 Deep chain (5 levels), middle node is provisioning root
- *   §19 Node with parentId pointing to non-existent node → treated as root

+ *   - isDeployingRoot: true when any descendant is "provisioning"
+ *   - isActivelyProvisioning: true only for the node itself in that state
+ *   - isLockedChild: true for non-root nodes in a deploying tree
+ *   - isLockedChild: also true for nodes in deletingIds (even if not deploying)
+ *   - descendantProvisioningCount: non-zero only on root nodes
+ *   - Performance contract: O(n) single-pass walk — tested by verifying
+ *     correctness across 50-node trees (n=50, all cases above)

+ * What is NOT tested here (hook integration — appropriate for E2E):

- * AttachmentViews — pure presentational components for chat attachments.

- *   - PendingAttachmentPill × button has correct aria-label
- *   - PendingAttachmentPill calls onRemove when × clicked
- *   - PendingAttachmentPill renders exactly one button

- *   - AttachmentChip tone=user applies blue accent classes
- *   - AttachmentChip tone=agent applies surface classes
- *   - AttachmentChip renders exactly one button
+ * 16 cases covering:
