* feat: add parent heartbeat to MCP server to prevent orphaned processes
MCP server now monitors its parent process every 30s. When the parent
dies (ppid changes to 1 on Unix), the server self-exits to prevent
orphaned node processes that accumulate over time.
- Checks ppid every 30s after server start
- Compares against initial ppid (handles reparenting)
- Timer uses unref() to not keep process alive artificially
- Unix-only (ppid=1 detection doesn't apply on Windows)

* fix: make cleanup() synchronous for consistent shutdown behavior
cleanup() only does synchronous work (clearInterval + process.exit),
so remove async to avoid inconsistent behavior when called from
setInterval callback vs signal handler vs awaited context.

* feat: configurable subprocess pool limit for SDK agents
Prevents runaway accumulation of Claude SDK agent subprocesses by
enforcing a configurable concurrency limit.
- New CLAUDE_MEM_MAX_CONCURRENT_AGENTS setting (default: 2)
- Promise-based waitForSlot() in ProcessRegistry (not polling per
review feedback on #830)
- Waiters are notified via unregisterProcess when a slot frees up
- SDKAgent.startSession() waits for a slot before spawning
- 60s timeout prevents indefinite waits

* fix: SDK Agent fails on Windows when username contains spaces
Fixes spawn failure on Windows when the user's path contains spaces
(e.g., C:\Users\Anderson Wang\).
Root cause:
- SDKAgent.ts returns full auto-detected path with spaces
- ProcessRegistry.ts cannot execute .cmd files when path contains spaces
Solution:
- SDKAgent: On Windows, prefer "claude.cmd" via PATH instead of full path
- ProcessRegistry: Use cmd.exe /d /c wrapper for .cmd files on Windows
This preserves argument boundaries (e.g., empty string values) while
properly handling paths with spaces.
Fixes#1014

On Linux, Bun's libuv calls fstat() on inherited pipe file descriptors
and crashes with EINVAL when the pipe originates from Claude Code's hook
system. This causes all PostToolUse hooks to fail silently, preventing
observations from being recorded.
The fix reads stdin entirely in the Node.js parent process (bun-runner.js)
before spawning Bun, then writes the buffered data to a fresh pipe created
by Node's child_process.spawn(). Bun receives a standard pipe that it can
fstat() without errors.
Changes:
- Add collectStdin() to buffer piped input in Node.js with 5s safety timeout
- Change stdio from 'inherit' to ['pipe'|'ignore', 'inherit', 'inherit']
- Write buffered stdin to child.stdin then close for proper EOF signaling
- Handle edge cases: TTY stdin, no stdin, read errors
Fixes#646

The marketplace root was hardcoded to `~/.claude/plugins/marketplaces/thedotmack`,
which does not exist on XDG-compliant setups (e.g. Nix-managed Claude Code) where
plugins are stored under `~/.config/claude/plugins/`.
This caused an ENOENT error on every SessionStart:
ENOENT: no such file or directory, open
'~/.claude/plugins/marketplaces/thedotmack/package.json'
Now the script:
1. Derives the base path from CLAUDE_PLUGIN_ROOT if available
2. Probes the XDG path (~/.config/claude/plugins/...)
3. Falls back to the legacy path (~/.claude/plugins/...)

When searching with a project parameter, the ChromaDB vector query was
not filtering by project. It only filtered by doc_type. This caused
larger projects to dominate the top-N results returned by ChromaDB,
effectively crowding out results from smaller projects before the
post-hoc SQLite project filter could take effect.
For example, with project A having 19,000 embeddings and project B
having 700, a search scoped to project B would return mostly project A
results from ChromaDB. After SQLite filtered by project, only 1-3
results from B would survive instead of the expected 20+.
The fix adds the project to the ChromaDB where clause using $and when
both doc_type and project filters are needed. This is applied in both
ChromaSearchStrategy.buildWhereFilter() and SearchManager.search().

Move the /make-plan and /do orchestrator commands from plugin/commands/
into OpenClaw skills (openclaw/skills/make-plan, openclaw/skills/do-plan).
Skills are auto-discovered by the agent and loaded on-demand via SKILL.md
frontmatter matching, reducing context cost vs always-loaded slash commands.
Register skill directories in openclaw.plugin.json via the skills array.

* feat: universalize observation feed emojis with config-driven system
Replace hardcoded AGENT_EMOJI_MAP with a three-tier approach:
1. User-pinned emojis via observationFeed.emojis.agents config
2. Deterministic auto-assign from pool using agentId hash
3. Configurable fallbacks for primary, Claude Code, and default emojis
Claude Code sessions now display "Claude Code Session" instead of the
working directory name. All emoji settings are exposed in the plugin
configSchema so the onboarding wizard AI can discover and configure them.

This commit addresses the issue of duplicate assistant messages appearing
in the conversation history by commenting out the lines that were
unnecessarily pushing assistant responses to the conversationHistory array.
The processAgentResponse function already handles adding assistant messages
to the conversation history, so these additional pushes were causing
duplicate entries.
Changes made:
- Commented out session.conversationHistory.push calls for assistant responses
in three locations within OpenRouterAgent.ts:
1. In the init response handling (around line 117)
2. In the observation response handling (around line 188)
3. In the summary response handling (around line 230)
This ensures that assistant messages are only added once to the conversation
history, preventing duplication while maintaining the intended functionality.

v1beta does not support newer models like gemini-3-flash, causing
silent 404 errors that back up the observation queue indefinitely.
Users with CLAUDE_MEM_GEMINI_MODEL=gemini-3-flash get zero observations
stored, with no visible error — the queue just grows silently.
Changes:
- Switch API URL from v1beta/models to v1/models (generateContent
works identically on both endpoints)
- Add gemini-3-flash to GeminiModel type and RPM limits
- Update test to match new endpoint

The summarize (Stop) and observation (PostToolUse) handlers throw
blocking errors (exit code 2) when optional input fields like
transcriptPath, toolName, or cwd are missing. This causes visible
hook errors on every session stop and after some tool uses.
Replace throws with graceful returns matching the existing pattern
used for worker-unavailable checks.

Add systemMessage field to HookResult so SessionStart can display a
colored timeline directly to the user in the CLI. The handler now
parallel-fetches both markdown (for Claude context) and ANSI-colored
(for user display) timelines, appending a viewer URL link.
Also update default settings to hide verbose token columns (read/work
tokens, savings amount) and disable full observation expansion, keeping
the cleaner index-only view by default.

Chroma requires client-side embeddings — the server is storage only.
The previous commit incorrectly removed @chroma-core/default-embed.
Uses DefaultEmbeddingFunction({ wasm: true }) which forces the WASM
backend instead of native ONNX binaries. Same model (all-MiniLM-L6-v2),
same embeddings, but works on all platforms without segfaults or
ENOENT errors (#1104, #1105, #1110).

- Add stderr capture to SDK spawn for diagnosing future process failures
- Exclude lockfiles from marketplace rsync and delete stale lockfiles

Three fixes for the OpenClaw plugin:
1. Fix MEMORY.md sync returning empty content
- syncMemoryToWorkspace() was querying basename(workspaceDir) as the
project name (e.g. 'workspace'), but observations are stored under
agent-scoped names like 'openclaw-main'
- Now queries both the base project and agent-scoped project name
- Passes EventContext through so the correct project can be derived
2. Add dedicated botToken support for observation feed
- New optional 'botToken' field in observationFeed config
- When set, sends observations directly via Telegram Bot API instead
of routing through the gateway's channel plugin
- Allows using a separate bot for the observation stream
3. Fix plugin kind for memory slot compatibility
- Changed plugin kind from 'integration' to 'memory' so OpenClaw
recognizes it as a valid memory slot plugin
- Fixes 'memory slot plugin not found' warning when
plugins.slots.memory = 'claude-mem' is configured
