Replace string-typed log levels with SDK LoggingLevel across the Logs
group components and LoggingScreen.
- LogControls: type currentLevel, visibleLevels, and all handlers with
LoggingLevel instead of string; type LOG_LEVELS array and LEVEL_COLORS
record with LoggingLevel
- LogStreamPanel: type visibleLevels as Record<LoggingLevel, boolean>
instead of Record<string, boolean>
- LoggingScreen: type currentLevel, onSetLevel, visibleLevels state,
and toggle handlers with LoggingLevel; extract NO_LEVELS_VISIBLE as
a module-level constant
- Stories already used LoggingLevel literals; updated type annotations
to use Record<LoggingLevel, boolean>
- No ConnectedView story changes needed (already passes valid
LoggingLevel values)

- Fix template-expanded URIs not rendering: construct synthetic Resource
from readState.uri when the URI is absent from the resources list
- Fix non-image blob content rendering raw base64: show placeholder
message; also handle audio blobs properly
- Hide mimeType display when multiple content items to avoid confusion
- Rename ResourceControls selectedTemplate → selectedTemplateUri for
consistency with selectedUri and selectedResourceUri

Replace ad hoc local types with MCP SDK schema types across the Resources
group components and ResourcesScreen, per the v2 UX interfaces plan.
- ResourceListItem: accept `resource: Resource | ResourceTemplate` instead
of flat `name`/`uri`; render `title ?? name`; delete local
`ResourceAnnotations` type
- ResourceControls: accept `Resource[]`, `ResourceTemplate[]`,
`InspectorResourceSubscription[]` + `selectedUri`/`selectedTemplate`
instead of `ResourceItem[]`/`TemplateListItem[]`/`SubscriptionItem[]`;
no-op on re-selecting

`contents: (TextResourceContents | BlobResourceContents)[]` instead of
flat `content: string`; use SDK `Annotations` (audience as Role[]);
`lastUpdated` as `Date` not `string`
- ResourceTemplatePanel: accept `template: ResourceTemplate` instead of
flat props; use SDK `Annotations`
- ResourceSubscribedItem: accept `subscription: InspectorResourceSubscription`
instead of flat `name`/`lastUpdated`; `lastUpdated` as `Date`
- ResourcesScreen: accept `Resource[]`, `ResourceTemplate[]`,
`InspectorResourceSubscription[]` + `selectedResourceUri`/
`selectedTemplateUri` + `ReadResourceState`; derive selections via
`find()`; add loading/error states

`SelectedResource`, `SelectedTemplate`, `ResourceAnnotations` types

- PromptMessagesDisplay: narrow type from `(PromptMessage | SamplingMessage)[]`
to `PromptMessage[]` per spec

derive selected prompt via `prompts.find()`; own `argumentValues` state
locally; reset arguments on tool switch

'disabled' variant on the Card theme, per AGENTS.md rules against
inline styles on components. Also picks up prettier formatting on
ResourcesScreen.

- ToolControls and PromptControls now manage searchText as local state
and filter their lists internally (matches on name + title/description)

payloads

- Rename StatusIndicator to ServerStatusIndicator across all files
- ServerCard: add activeServer/onSetActiveServer props for coordinated
connection flow — when a card's toggle is switched on, it sets itself
as the active server, shows "Connecting" status, and dims all other
cards (opacity + pointerEvents none + inert for full keyboard blocking)
- ServerListScreen: manage activeServer state internally, pass to cards;
switch to full-width layout with 3-column grid and scrollable card area
- ServerCard: move "Test Client Features" dropdown above ContentViewer
with min-height row for consistent card heights
- ToolResultPanel: move Clear button to top-right header row
- ToolDetailPanel: right-align Execute Tool button, size md, not full-width
- ListChangedIndicator: bump Refresh button to size sm
- ToolsActive story: expand to 30 tools with titles
- UnconnectedView stories: all servers disconnected, remove Connecting story

ResourceControls now manages its own search state internally and filters
all three accordion sections (URIs, Templates, Subscriptions) by name
and URI. Added ListToggle to expand/collapse all sections. Moved Export
JSON and Clear All buttons from HistoryControls sidebar to the
HistoryListPanel header for better proximity to the data they act on.

- Extract ResourceControls group component from ResourcesScreen:
title, search, list-changed indicator, and three-section accordion
(URIs, Templates, Subscriptions) with per-panel ScrollArea.Autosize
- Refactor ResourcesScreen to sidebar+panel Flex layout matching
HistoryScreen/LoggingScreen pattern (ScreenLayout, Sidebar, SidebarCard)
- Each accordion panel dynamically computes max height based on how many
sections are open, dividing available space evenly
- Accordion uses controlled state (value/onChange) to track open sections
- Sidebar card sizes to content naturally (compact when collapsed,
grows with open sections, capped by scroll areas)
- Right panel wrapped in ScrollArea.Autosize for long content
- Add AllSections story with 20 URIs, 7 templates, 8 subscriptions
- Add more templates and subscriptions to ConnectedView ResourcesActive

- Redesign TaskCard to match v1 Task Details panel layout:
header with task ID + status badge + cancel button,
always-visible summary row (Status, Last Updated, Created At, TTL)
with Expand/Collapse button, expandable section with status message,
progress bar, error, and Full Task Object JSON viewer
- Add TaskControls group: search input + status filter dropdown +
Refresh/Clear History buttons (mirrors HistoryControls pattern)
- Add TaskListPanel group: scrollable panel with ListToggle for
expand/collapse all, splits tasks into Active/Completed sections
with counts, filters by search text and status
- Refactor TasksScreen to sidebar + panel layout matching HistoryScreen:
manages search/filter state internally, flat tasks array
- Simplify TaskCard callbacks to just onCancel

HeaderRightGroup, SectionTitle, SummaryRow, DetailRow) for
AGENTS.md compliance
- Update all stories (TaskCard, TaskControls, TaskListPanel,
TasksScreen, ConnectedView)

- Rename ResourceTemplateInput to ResourceTemplatePanel with panel layout
(title header, URI with live variable preview, labeled inputs, Read Resource button)

single onReadResource(uri) callback returns fully resolved URI
- Extract ResourceSubscribedItem group component with name, timestamp, and
subtle Unsubscribe button
- Add hover state to listItem variant via theme classNames + App.css pseudo-selector
- Add Refresh button to ResourcePreviewPanel
- Refactor ResourcesScreen callbacks: onSelectUri, onSelectTemplate,
onReadResource, onSubscribeResource, onUnsubscribeResource replace
per-item onClick/onUnsubscribe props; screen wires callbacks to children
- Define data-only types (ResourceItem, TemplateListItem, SubscriptionItem,
SelectedResource, SelectedTemplate) separating data from callbacks
- Extract named .withProps() subcomponents (FooterRow, AnnotationGroup,
ActionGroup, Spacer) for AGENTS.md compliance
- Update all stories (ResourceTemplatePanel, ResourcesScreen, ConnectedView)
