Replace single-client model (m_client/m_readBuffer/m_initialized)
with a ClientState vector. Each client gets its own read buffer and
initialized flag. Responses route to m_currentSender (set during
request processing); notifications broadcast to all initialized
clients.
Re-entrancy guard in onReadyRead: re-resolve ClientState after each
processLine() call since sendJson flush can re-enter the event loop
and trigger onDisconnected, removing the client mid-iteration.
Tests: 378-line test_mcp exercising connect, initialize, tools/list,
disconnect one client, notification broadcast, and serial requests
against a MockMcpServer with the same multi-client architecture.
Scanner engine:
- Add constrainRegions to ScanRequest — callers pass address ranges
that are intersected with provider regions before scanning
- Merge overlapping/adjacent constraints to prevent duplicate results
- Fix final-chunk overlap: skip overlap advance on last chunk to avoid
re-scanning the tail of a region
MCP tools:
- scanner.scan: value scans (int/float types) with optional region
constraints, returns first 15 addresses
- scanner.scan_pattern: pattern/signature scans with wildcards
- source.modules: list loaded modules with base address and size
- mcp.reconnect: graceful client disconnect for IDE reconnection
- parseInteger() helper for hex string args (avoids JSON double
precision loss on 64-bit addresses)
- Fix baseRelative semantics in hex.read/hex.write (was inverted)
- Auto-set tree.baseAddress from provider after process attach
Scanner panel:
- runValueScanAndWait() and runPatternScanAndWait() for blocking
scan execution from MCP/automation code
Tests: 41 new test cases for constrainRegions covering gaps, partial
overlap, adjacent regions, writable filter, degenerate ranges,
overlapping constraints, boundary patterns, alignment, and value
types at region start/end positions.
- MCP bridge: guard against use-after-free when client disconnects
during sendJson flush by re-checking m_client after write
- Scanner engine: fix chunk overlap advancing past region end on
final chunk; fix fallback region flags for providers without
enumerateRegions
- Build scripts: prefer GCC MinGW over LLVM-MinGW in PATH detection
Expose PEB address via provider interface and query it in the
ProcessMemory plugin using NtQueryInformationProcess. The new
process.info MCP tool returns the PEB VA and enumerates TEBs by
querying thread information via NtQuerySystemInformation and
NtQueryInformationThread for each thread in the target process.
- Tree line connectors (Unicode box-drawing ├─ └─ │) at arbitrary depth
- Fix editor overwriting tree chars at depth 2+ (applyMarginText Pass 2)
- Scanner: unknown value scan, comparison rescan modes (Changed/Unchanged/Increased/Decreased)
- New Tailwind theme (tw.json), WCAG contrast fixes for warm/mid themes
- Tooltip system (rcxtooltip.h)
- Comprehensive README rewrite with full feature inventory
- New tests for compose tree lines, scanner, tooltips

Add Cheat Engine-style scan conditions: Unknown Value captures all
aligned addresses as baseline, then Changed/Unchanged/Increased/Decreased
narrow results by comparing current vs previous values. Exact Value
mode unchanged. Also fix find bar search box height to match buttons
and improve MCP bridge instructions.
- Add timestamps to ValueHistory ring buffer, expose via new MCP tool
node.history, show relative time in popup ("26s ago", "2m ago")
- Add "Clear Value History" right-click menu for single and multi-select
- Add Ctrl+F find bar to RcxEditor with live search, Enter-to-next, wrap
- Fix Ctrl+F in workspace dock to auto-focus search field
- Add "Change to float" quick-convert for Hex32 right-click menu
- Sort workspace explorer by children count descending (most fields first)
- Fix provider->base() overwriting saved base address from .rcx files
- Add formula support to MCP change_base operation
- Re-evaluate baseAddressFormula on provider attach in selectSource()

Rewrite C++ generator for Vergilius-style output: inline anonymous
structs/unions, reference opaque types by name with struct keyword
prefix, size comments, aligned offset comments, no anon_ stubs.
Fix struct type name not clickable in editor headers (headerTypeNameSpan
assumed "struct TYPENAME" format but named structs use bare name).
Add static_assert toggle in Options > Generator, default off.
Fix item view highlight bleed: patch PE_PanelItemViewRow to use
theme.hover so row background matches CE_ItemViewItem.
- Add ShimmerLabel widget with animated glow band for MCP tool activity
- Separate app/MCP status channels (setAppStatus/setMcpStatus/clearMcpStatus)
- 750ms delayed clear so shimmer stays visible after fast tool calls
- MCP auto-starts on launch by default
- Remove "Ready" text that was overwriting useful status info
- Add statusText field to project.state MCP response
- Enum inline editing: name/value commit handling, auto-sort by value
- Bitfield support in PDB import with proper container nodes
- Per-member hover/selection highlighting (kMemberBit encoding)
- Context menu fixes for enum/bitfield member lines
- MCP pagination (limit/offset), includeMembers param, tree.search tool
- MCP status bar activity indicator for tool calls
- PDB anonymous type inlining: inline <unnamed-tag> types as children
- Skip anonymous pointer targets to prevent root orphans
- Enum import diagnostics for debugging missing enums
- Show relative hex offset on array element separators ([N] +0x...)
- Dim fold arrows and add hover highlight for better visibility
- Extend fold/chevron click areas for easier interaction
- Add type picker popup for array element type and pointer target editing
- Remove process_provider.h in favor of plugin-based provider system
- Expand compose/format to handle struct-of-array type names and widths

Provider base address now stays in sync with tree base address when
changed via ChangeBase command, fixing reads from arbitrary memory
regions like KUSER_SHARED_DATA at 0x7FFE0000. ReadProcessMemory
handles partial reads gracefully. Snapshot extent uses tree-based
calculation instead of provider size to avoid oversized reads.
MCP source.switch gains pid parameter for programmatic process attach.
MCP server starts by default with logging and slow mode support.

Embedded JSON-RPC server over named pipes (rcx-mcp) enabling external
tools like Claude Code to inspect and manipulate the node tree, read/write
hex data, switch sources, and trigger UI actions. Includes stdio adapter
(rcx-mcp-stdio) for stdin/stdout transport. Server is stopped by default;
user starts via File > Start MCP Server.
Also extracts MainWindow class declaration to mainwindow.h and improves
type selector popup Esc button styling.
