Collapsible blocks:
- Thinking, tool_call, and tool_result messages start collapsed by default
- Chevron toggle in the header expands/collapses content
- Collapsed preview shows line count (thinking), tool name (tool_call),
or first line truncated to 120 chars (tool_result)
- Collapsed blocks skip expensive markdown/highlight rendering entirely
Diff rendering:
- Detect unified diff content via hunk header + add/delete line heuristics
(requires both @@ headers AND +/- lines to avoid false positives on
YAML or markdown lists with leading dashes)
- Render diffs with color-coded line classes: green additions, red
deletions, blue hunk headers, and muted meta/header lines
- Add full diff-view CSS with background tints and block-level spans
Header actions (appear on hover):
- Copy link button: copies a #msg-{uuid} anchor URL to clipboard with
a checkmark confirmation animation
- Redaction toggle button: replaces the previous whole-card onClick
handler with an explicit eye-slash icon button, colored red when
selected — more discoverable and less accident-prone
Style adjustments:
- Raise dimmed message opacity from 0.2/0.45 to 0.35/0.65 for better
readability during search filtering
- Fix btn-secondary hover border using explicit rgba value instead of
Tailwind opacity modifier (which was generating invalid CSS)
- Position copy button below language label when both are present
- Simplify formatTimestamp with isNaN guard instead of try/catch
- Use fixed h-10 header height for consistent vertical alignment
- Brighten user and assistant message backgrounds (bg-surface-overlay)
to visually distinguish them from other message types

MessageBubble: Replace border-left colored bars with rounded cards featuring
accent strips, category dot indicators, and timestamp display. Use shared
escapeHtml. Render tool_result, hook_progress, and file_snapshot as
preformatted text instead of markdown (avoids expensive marked.parse on
large JSON/log blobs).
ExportButton: Add state machine (idle/exporting/success/error) with animated
icons, gradient backgrounds, and auto-reset timers. Replace alert() with
inline error state.
FilterPanel: Add collapsible panel with category dot colors, enable count
badge, custom checkbox styling, and smooth animations.
SessionList: Replace text loading state with skeleton placeholders. Add
empty state illustration with descriptive text. Style session items as
rounded cards with hover/selected states, glow effects, and staggered
entry animations. Add project name decode explanation comment.
RedactedDivider: Add eye-slash SVG icon, red accent color, and styled
dashed lines replacing plain text divider.
useFilters: Remove unused exports (setAllCategories, setPreset, undoRedaction,
clearAllRedactions, selectAllVisible, getMatchCount) to reduce hook surface
area. Match counting moved to App component for search navigation.
SessionList.test: Update assertions for skeleton loading state and expanded
empty state text.

Full React 18 client application for interactive session browsing:
app.tsx:
- Root component orchestrating session list, viewer, filters, search,
redaction controls, and export — wires together useSession and
useFilters hooks
- Keyboard navigation: j/k or arrow keys for message focus, Escape to
clear search and redaction selection, "/" to focus search input
- Derives filtered messages, match count, visible UUIDs, and category
counts via useMemo to avoid render-time side effects
hooks/useSession.ts:
- Manages session list and detail fetching state (loading, error,
data) with useCallback-wrapped fetch functions
- Auto-loads session list on mount
hooks/useFilters.ts:
- Category filter state with toggle, set-all, and preset support
- Text search with debounced query propagation
- Manual redaction workflow: select messages, confirm to move to
redacted set, undo individual or all redactions, select-all-visible
- Auto-redact toggle for the sensitive-redactor module
- Returns memoized object to prevent unnecessary re-renders
components/SessionList.tsx:
- Two-phase navigation: project list → session list within a project
- Groups sessions by project, shows session count and latest modified
date per project, auto-drills into the correct project when a session
is selected externally
- Formats project directory names back to paths (leading dash → /)
components/SessionViewer.tsx:
- Renders filtered messages with redacted dividers inserted where
manually redacted messages were removed from the visible sequence
- Loading spinner, empty state for no session / no filter matches
- Scrolls focused message into view via ref
components/MessageBubble.tsx:
- Renders individual messages with category-specific Tailwind border
and background colors
- Markdown rendering via marked + highlight.js, with search term
highlighting that splits HTML tags to avoid corrupting attributes
- Click-to-select for manual redaction, visual selection indicator
- Auto-redact mode applies sensitive-redactor to content before render
- dangerouslySetInnerHTML is safe here: content is from local
user-owned JSONL files, not untrusted external input
components/FilterPanel.tsx:
- Checkbox list for all 9 message categories with auto-redact toggle
components/SearchBar.tsx:
- Debounced text input (200ms) with match count display
- "/" keyboard shortcut to focus, × button to clear
components/ExportButton.tsx:
- POSTs current session + visible/redacted UUIDs + auto-redact flag
to /api/export, downloads the returned HTML blob as a file
components/RedactedDivider.tsx:
- Dashed-line visual separator indicating redacted content gap
lib/types.ts:
- Re-exports shared types via @shared path alias for client imports
lib/constants.ts:
- Tailwind CSS class mappings per message category (border + bg colors)
lib/markdown.ts:
- Configured marked + highlight.js instance with search highlighting
that operates on text segments only (preserves HTML tags intact)
styles/main.css:
- Tailwind base/components/utilities, custom scrollbar, highlight.js
overrides, search highlight mark, redaction selection outline,
message dimming for non-matching search results
index.html + main.tsx:
- Vite entry point mounting React app into #root with StrictMode
