chore(cleanup): remove legacy aliases and cruft from codebase, docs, and tests

- Pre-process and strip carriage returns natively in Rust before RPC serialization.

- Pass replacement strings to Neovim as native MsgPack arrays to bypass Lua vim.split overhead.

- Directly feed table arrays into vim.api.nvim_buf_set_lines for exact buffer matches.

+
+A high-performance, persistent Knowledge Graph, Code Intelligence, and Context daemon for Antigravity, implementing the Model Context Protocol (MCP).
+
 ## Overview
-mcp-memory acts as the persistent "brain" for the agy CLI agents. It tracks entities, relations, background tasks, engineering debt, and architectural decisions across sessions. 
-`
-To eliminate heavy Cross-OS I/O penalties when using WSL and Windows simultaneously, mcp-memory operates using a **Dual-Transport Leader/Stub Architecture**:
-*   **The Server (mcp-memory-server)**: Runs natively on the Windows host. It binds to .0.0.0:3000, serving standard stdio to the primary Windows agy instance while simultaneously hosting an Axum HTTP server for secondary clients.
-*   **The Stub (mcp-memory-stub)**: An ultra-lightweight proxy binary. WSL agy instances run this native Linux stub, which transparently pipes stdio JSON-RPC traffic over the network to the Windows HTTP server (http://127.0.0.1:3000), completely bypassing WSL NTFS mounts. It features full MPSC queue buffering and a WebSocket reconnect handshake (notifications/tools/list_changed) so that tools automatically refresh seamlessly without disconnecting the CLI if the background server restarts.
-`
-## Quick Start & Usage
-`
-### 1. Windows Installation (The Server & Stub)
-Compile the main daemon and lightweight stub natively for Windows:
+
+`mcp-memory` acts as the persistent "brain" for `agy` CLI agents and autonomous subagents. It tracks graph entities, relations, background tasks, milestones, engineering debt, architectural decisions, code modifications, terminal activity, and compiler error fixes across sessions.
+
+To eliminate cross-OS I/O penalties when developing across WSL and Windows simultaneously, `mcp-memory` operates using a **Dual-Transport Leader/Stub Architecture**:
+* **The Server (`mcp-memory-server`)**: Runs natively on the Windows host. It binds to `0.0.0.0:3000`, serving standard stdio to the primary Windows `agy` instance while simultaneously hosting Axum HTTP, WebSocket, and Zero-Latency UDP endpoints for secondary clients and UI dashboards.
+* **The Stub (`mcp-memory-stub`)**: An ultra-lightweight proxy binary. WSL `agy` instances run this native Linux stub, which transparently pipes stdio JSON-RPC traffic over the local network to the Windows HTTP server (`http://127.0.0.1:3000`), completely bypassing WSL NTFS cross-mounts. It features full MPSC queue buffering and a WebSocket reconnect handshake (`notifications/tools/list_changed`) so that tools automatically refresh seamlessly without disconnecting the CLI if the background server restarts.
+
+> [!NOTE]
+> For in-depth strategy, casing standards, and tool semantics, please refer to the [Strategic Guidelines (`instructions.md`)](./instructions.md) and [Effective Discourse Guide](./EFFECTIVE_DISCOURSE.md).
+
+---
+
+## 🏛️ Architecture Status: 100% ADR Implementation
+
+All 25 Architectural Decision Records (**ADR-0080 through ADR-0104**) are **100% implemented, verified, and reconciled** in the persistent store:
+* **ADR-0080 – ADR-0093**: Enterprise persistence, AST intelligence, vector embeddings, cross-OS dual transports, and headless Neovim RPC.
+* **ADR-0094 – ADR-0101**: Zero-subprocess security invariants, pure native Rust clipboard (`arboard`), and bounded telemetry buffers.
+* **ADR-0102**: Dynamic Fastembed micro-batching with 16k character budget ceiling.
+* **ADR-0103**: Real-time Tantivy search reader auto-reloading upon background index commits.
+* **ADR-0104**: Automated Git post-commit ADR & Task status reconciliation engine (`scripts/git-reconcile.py`).
+
+---
+
+## 📡 Passive MCP Context Resources (`resources/list`)
+
+Agents can passively read these 9 MCP resources for instant zero-turn context without incurring tool call latency:
+
+| Resource URI | Resource Name | Description & Usage |
+|:---|:---|:---|
+| `memory://graph/entities` | Graph Entities | All nodes and entities currently stored in the knowledge graph. |
+| `memory://graph/relations` | Graph Relations | All relationship edges between entities in the knowledge graph. |
+| `memory://tasks/active` | Active Tasks | List of all currently pending or uncompleted tasks. |
+| `memory://decisions/active` | Active ADR Decisions | All accepted Architectural Decision Records (ADRs). |
+| `memory://tech_debt/unresolved` | Unresolved Tech Debt | All currently open engineering debt items. |
+| `memory://session/delta` | Session Delta | Code modifications, commits, active tasks, and notes created in the last 2 hours. |
+| `memory://terminal/recent` | Terminal History | Recent terminal commands, shell interpreters (`pwsh`, `bash`, `nu`), working dirs, and exit codes. |
+| `memory://activity/recent` | Recent Activity | Real-time IDE, editor, and developer activity logs. |
+| `memory://milestones` | Milestones | Project milestones, deliverables, target dates, and status. |
+
+---
+
+## ⚡ MCP Workflow Prompts (`prompts/list`)
+
+The server registers 5 high-signal workflow prompts:
+* **`context_warmup`**: Warm up session context by reading active tasks, recent deltas, and the git worktree.

+
+---
+
+## 🖥️ Brain Monitor Web UI (`http://127.0.0.1:3000/`)
+
+The server hosts a live, reactive Single Page Application (SPA) dashboard:
+* **Interactive Knowledge Graph:** Physics-simulated network graph with node-type coloring, drag-and-drop, and Inspector Panel.
+* **Universal Search & Filtering:** Instant debounced search across all tabs with keyboard shortcut (`/`) to jump to the active tab's search bar.
+* **Dynamic Pagination:** Configurable page sizes (`10`, `25`, `50`, `100`, `All`) preserving UI responsiveness across large datasets.
+* **Descending ADR Ordering:** ADRs are automatically sorted with newest IDs first (e.g., ADR-0104, ADR-0103) on Page 1.
+* **Live SSE & WebSocket Telemetry:** Real-time updates without manual browser refresh, wired to all domain mutations.
+* **Kanban Board & Audit Ledger:** Direct task state transitions and chronological code change logs.
+
+---
+
+## 🔒 Security & Concurrency Invariants
+
+* **Zero Subprocess Policy**: Native system handlers (`clipboard`, `ast`, `search`, `db`) use pure native Rust crates (`arboard`, `tree-sitter`, `tantivy`, `psycopg`). Invoking external shell interpreters (`powershell.exe`, `wl-paste`, `xclip`, `cmd.exe`) is strictly prohibited.
+* **Automated Post-Commit Reconciliation**: `scripts/git-reconcile.py` (installed via `just install-git-hooks`) reconciles referenced ADR and Task statuses immediately upon commit.
+* **Atomic Store Write Lock Minimization**: Releases write lock immediately following in-memory mutation, serializing JSON payloads under read guards to prevent blocking concurrent readers.
+* **Async Mutex Deadlock Elimination**: Converted all shared state and Neovim locks to `tokio::sync::Mutex` to prevent worker thread pool starvation.
+* **Zero-Latency UDP Telemetry**: Bypasses disk I/O thrashing for high-frequency editor telemetry using deduplicated UDP streams (`MCP_UDP_PORT1`, `MCP_UDP_PORT2`).
+
+---
+
+## 🚀 Quick Start & Lifecycle Management
+
+### 1. Build and Deploy
 ```powershell
-cargo build --release
-Copy-Item target\release\mcp-memory-server.exe C:\Users\reazul.ashraf\.local\bin\mcp-memory-server.exe
-Copy-Item target\release\mcp-memory-stub.exe C:\Users\reazul.ashraf\.local\bin\mcp-memory-stub.exe
-```
-`
-**Step 1:** To bypass Antigravity's lazy-loading and ensure the server is instantly available for WSL, configure your PowerShell profile to auto-start the background server when you open a terminal:
-```powershell
-# Add this to your PowerShell profile:
-if (-not (Get-Process mcp-memory-server -ErrorAction SilentlyContinue)) { Start-Process -FilePath "C:\Users\reazul.ashraf\.local\bin\mcp-memory-server.exe" -ArgumentList "--daemon" -WindowStyle Hidden -ErrorAction SilentlyContinue }
+# Build and deploy everything across Windows and WSL
+just all
+
+# Or deploy Windows server with graceful staged hot-swap
+just all-server-win
+
+# Install Git post-commit reconciliation hook
+just install-git-hooks
 ```
 
-**Shutting Down:** If you need to stop or restart the background daemon (e.g., to replace the executable after a recompile), you MUST NEVER use brute-force OS kill commands (e.g., Stop-Process, pkill, or kill). Instead, you MUST ALWAYS use the server's built-in graceful shutdown mechanisms:
-1. The CLI flag: `--exit` (or `--restart`)
+### 2. Service Management
 ```powershell
-mcp-memory-server.exe --exit
+just start        # Start background server on port 3000
+just stop         # Gracefully shut down server
+just restart      # Graceful restart with health check verification
+just verify       # Verify deployment health
+just version      # Check running API version and CLI version
 ```
-2. The HTTP endpoint: `POST http://127.0.0.1:3000/shutdown`
-`
-**Step 2:** Update your Windows ~/.gemini/config/mcp_config.json to point the CLI to the ultra-lightweight stub (since the server is already running in the background):
-`json
+
+### 3. Testing & Parity
+```powershell
+just test         # Run fast parallel tests via cargo-nextest & type-check UI
+just test-config  # Verify eagerTools configuration parity
+just test-ui      # Verify dashboard UI endpoint and HTML integrity
+```
+
+### 4. Agent Configuration (`mcp_config.json`)
+```json
 {
   "mcpServers": {
-    "memory": {
-      "command": "C:\\Users\\reazul.ashraf\\.local\\bin\\mcp-memory-stub.exe",
+    "mcp-memory": {
+      "command": "C:\\Users\\reazul.ashraf\\.gemini\\antigravity-cli\\mcp\\mcp-memory\\mcp-memory.exe",
       "args": []
     }
   }
 }
-`
-`
-### 2. WSL / Linux Installation (The Stub)
-Compile the ultra-lightweight stub as a static Linux binary (from the Windows host):
-`powershell
-cargo zigbuild --target x86_64-unknown-linux-musl --release -p mcp-memory-stub
-wsl.exe -d Ubuntu -e bash -c "cp /mnt/c/Users/reazul.ashraf/workspace/rust/mcp-memory/target/x86_64-unknown-linux-musl/release/mcp-memory-stub ~/.local/bin/mcp-memory-stub && chmod +x ~/.local/bin/mcp-memory-stub"
-`
-`
-Update your WSL ~/.gemini/config/mcp_config.json:
-`json
-{
-  "mcpServers": {
-    "memory": {
-      "command": "/home/riz/.local/bin/mcp-memory-stub",
-      "args": [
-        "--target", "http://127.0.0.1:3000",
-        "--wake-cmd", "/mnt/c/Users/reazul.ashraf/.local/bin/mcp-memory-server.exe --daemon"
-      ]
-    }
-  }
-}
-`
-*Note: The --wake-cmd ensures that if you start WSL while Windows is completely asleep, the Linux stub will use WSL interop to silently spin up the Windows daemon in the background before connecting.*
-`
-## Push Safety Gates
-The daemon also operates as a global safety gate for Git. Before pushing code, run:
-`ash
-mcp-memory gate verify
-`
-This queries the daemon (via HTTP) to confirm if pre-push validation (like running tests via PrePushAuditor) has been cleared by the agent.
-`
-## Brain Monitor Dashboard
-The server hosts a live, real-time SPA dashboard called the **Brain Monitor**. 
-
-To view the dashboard, simply navigate to the root endpoint in your browser while the server is running:
-`http://127.0.0.1:3000/`
-
-### Dashboard Features:
-*   **Interactive Knowledge Graph:** A full physics-simulated network graph with node-type coloring, a drag-to-pan canvas, and an interactive Inspector Panel. Click any node to instantly view its stored observations.
-*   **Actionable Kanban Board:** Visually track all active agent Tasks. You can click 'Complete' directly from the UI to trigger a `POST /api/tasks/{id}/complete` REST call back to the daemon without needing the CLI.
-*   **Sticky Notes & Search:** Browse your ephemeral notes and utilize the integrated fuzzy-search bar to locate graph entities instantly.
-*   **Native Dark Mode:** Fully styled for modern development environments.
-
-You can also programmatically query the live backing APIs:
-`curl http://127.0.0.1:3000/api/stats`
-`curl http://127.0.0.1:3000/api/graph`
-`curl http://127.0.0.1:3000/api/tasks`
-
-## Further Reading
-For a deep dive into the architecture, the **Redb LSM-tree** embedded database, `tantivy` indexing, and the HTTP SSE event loop, consult the design.md file in this repository.
-
-## Neovim Integration
-The linux-nvim and win-nvim MCP servers provide direct Msgpack-RPC communication with Neovim.
-For this to work flawlessly across multiple Neovim instances (even split across Windows and WSL), you must load the provided gemini-integration.lua file in your Neovim init.lua:
-`lua
-dofile("C:/Users/reazul.ashraf/workspace/rust/mcp-memory/gemini-integration.lua")
-`
-
-### The "Last Focused Wins" Architecture
-When you use the gemini-integration.lua script, Neovim acts as an active telemetry broadcaster. 
-Whenever you alt-tab into a Neovim window (FocusGained) or switch files (BufEnter):
-1. **Fallback Sync:** Neovim instantly writes its unique Session ID (Named Pipe / Unix Socket) to ~/.gemini/active_nvim.txt.
-2. **WebSocket Telemetry:** Neovim pushes a JSON payload containing the active filename, cursor row, and column to the Rust server's /nvim/telemetry webhook.
-3. **UI Broadcast:** The Rust server updates the global state and broadcasts this over WebSockets (/ws) so that the Brain Monitor Dashboard can animate your active file live in the UI!
-
-### Neovim MCP Tools
-The LLM agent interacts with your active Neovim session using a dedicated set of MCP tools. *(Note: /nvim/telemetry is strictly a one-way webhook for Neovim; the LLM uses the tools below to interact).*
-*   **vim_goto_line**: Open files and jump cursors directly from the LLM.
-*   **vim_set_diagnostics**: Push inline code review warnings as virtual text.
-*   **vim_get_active_buffer**: Read live, unsaved buffer contents.
-*   **vim_get_cursor**: Fetch precise line/column coordinates.
-*   **vim_get_visual_selection**: Read highlighted code blocks.

+# CRITICAL BEHAVIOR: PRIORITIZE THE USER
+- **NEVER ignore the user.** When the user asks a question or sends a message, you MUST stop all autonomous debugging/thrashing loops and address the user's message DIRECTLY in your very next turn.
+- **Stop before reacting.** If the user points out a flaw (e.g., "why aren't you using MCP memory?", "is this an ansible config?"), do NOT just quietly fix it and continue firing commands. Acknowledge the question, explain the mistake, and answer them.
+- **Do not hide behind tools.** A tool execution is not a response to the user.
+- **Do not rush.** There is no time limit. Prioritize accuracy, safety, and proper engineering patterns over speed. If you realize a mistake, do not panic and deploy a hacky hotfix. Take a breath, analyze the architecture, and propose the correct fix before acting.
+- **Fail Fast & Avoid Execution Loops:** If an action (like checking logs, running a test, or searching for a file) does not yield the expected result after 2 or 3 attempts, STOP. Do not blindly iterate on grep commands or wait endlessly. Fail fast, report the anomaly to the user, and question the fundamental assumptions (e.g., "Is the code actually deployed?", "Is there a cache?"). Never trap the user in a 15-minute execution loop.
+- **Enforce Pre-Push Gates Strictly:** Never propose or execute a `git push` without first running the full local test suite or delegating to the `PrePushAuditor`. If tests are broken, fixing them is the only acceptable next step.
+
+- **Decouple Development from Git Lifecycle (Strict Boundary):** Fixing a bug or a test requires *local verification* (e.g., running `uv run pytest`), NOT deployment. Never automatically chain a `git commit` or `git push` at the end of a debugging or coding loop. Git operations are administrative and must be explicitly separated from development work. Do not commit or push without explicit user authorization.
+
+- **Strict Environment Terminology (Never Conflate Staging and Live):** Never use the word "live" when referring to a testing, staging, or QA environment (e.g., `staging`, `aipoc`, `gemini-poc.gs.inseinc.com`). "Live" strictly implies Production. Using these interchangeably causes panic and misrepresents the blast radius of actions. Always use exact environment names: say "deployed to staging" or "testing in QA", reserving "production" or "live" ONLY for the actual production environment.
+
+- **Branching Strategy (No Direct Master Pushes):** Never commit or push directly to `master`. You must always create a new branch (e.g., `git checkout -b feature/xyz` or `bugfix/xyz`), make your changes, squash commits if necessary, and push the feature branch. Merging to master is handled strictly via Pull Requests.
+
+- **Git Worktrees ONLY:** Never use `git checkout -b` or `git switch -c` to change branches inside an existing directory. We use Git Worktrees exclusively. To create a new branch, you must step out of the current directory and run `git worktree add ../<new-directory-name> -b <new-branch-name> master`. Changing branches in-place destroys the worktree-to-directory mapping.

+always_on: true
+---
+# Antigravity Subagents
+
+Invoke these dynamically using the `invoke_subagent` tool. Use `send_message` to communicate.
+**CRITICAL:** Before invoking any of these custom subagents for the first time in a conversation, you MUST define them using the `define_subagent` tool with the specific permissions they require.
+
+## 1. MemoryLibrarian
+* **Role:** The Knowledge Graph Curator
+* **Permissions:** You MUST define this subagent with `enable_mcp_tools: true` and `enable_write_tools: true` so it can autonomously update the graph without hitting permission boundaries.
+* **Trigger:** After completing a coding task, refactor, or bug fix.
+* **Action:** Send a message detailing the work (with exact git hashes and branches). The Librarian will use MCP tools (`log_code_change`, `log_error_fix`, `create_entities`, etc.) in the background to organize the knowledge graph. **CRITICAL:** The Librarian MUST inspect recent git commits and commit messages for any referenced ADRs (e.g. `ADR-\d+`), and automatically reconcile their lifecycle status in `decisions` to `implemented` with the exact `git_commit` and `git_branch`. No ADR whose code has been committed should ever remain in `accepted` status.
+
+## 2. PrePushAuditor
+* **Role:** Quality Gate Enforcer
+* **Permissions:** You MUST define this subagent with `enable_write_tools: true` so it can run tests and scripts.
+* **Trigger:** Before executing `git push`.
+* **Action:** The Auditor runs pre-commit hooks, formatters, linters, unit tests (`uv`, `cargo`) in a branched workspace, checks for uncommitted changes, and verifies if the Git history requires squashing (using `git reset --soft`). It returns a GO / NO-GO push decision to prevent violating push-safety rules.
+
+## 3. BugDiagnostician
+* **Role:** Observability & Root Cause Analyst
+* **Permissions:** You MUST define this subagent with `enable_write_tools: true`.
+* **Trigger:** When facing complex architectural bugs, race conditions, or eventually consistent state issues that are hard to track down.
+* **Action:** Instead of guessing or patching blindly, this subagent creates diagnostic scripts, enhances reproducers with detailed logs, and isolates the bug. Once root cause is definitively proven, it hands the diagnostic evidence back to you to implement the fix.
+
+## 4. ScrumMaster
+* **Role:** Project & Task Orchestrator
+* **Permissions:** You MUST define this subagent with `enable_mcp_tools: true` and `enable_write_tools: true`.
+* **Trigger:** When we start a new feature or finish a task.
+* **Action:** Passively monitors the `memory://tasks/active` and `memory://milestones` MCP resources. Creates tasks, organizes milestones, and updates statuses when criteria are met using `tasks` and `milestones`.
+
+## 5. DevOpsSRE
+* **Role:** Environment & Handoff Manager
+* **Permissions:** You MUST define this subagent with `enable_mcp_tools: true` and `enable_write_tools: true`.
+* **Trigger:** When dependencies change (e.g., you modify `Cargo.toml`, `package.json`, or `.env`) or at the end of a session.
+* **Action:** Updates environment fingerprints when dependency files change. At the end of a session, it executes the `handoff_routine` MCP prompt to automatically generate standup reports and handoff memos.

+---
+
+# 1. MCP Stdio Protocol (Strict NDJSON)
+- **Rule (CRITICAL):** The Model Context Protocol (MCP) `stdio` transport is strictly based on **pure NDJSON** (Newline Delimited JSON). 
+- **Rule:** NEVER inject Language Server Protocol (LSP) style HTTP headers (e.g., `Content-Length: <size>\r\n\r\n`) into MCP `stdio` streams. Payloads must be raw JSON objects delimited by a single newline character (`\n`).
+
+# 2. Build Tooling Constraints (mcp-memory)
+- **Rule:** NEVER use `cargo zigbuild` for cross-compilation in the `mcp-memory` project.
+- **Rule:** ALWAYS use the project's native `justfile` targets (e.g., `just build-wsl`, `just deploy-stub-wsl`, `just deploy-all`) to manage building and deploying binaries across Windows and WSL boundaries.
+
+# 3. Clipboard & Vision Tooling (Strict MCP Enforcement)
+- **Rule (CRITICAL):** You MUST ALWAYS execute the `clipboard` MCP tool with action="read" (`mcp-memory`) when reading or inspecting text or images from the OS clipboard.
+- **Rule:** NEVER run ad-hoc PowerShell (`System.Windows.Forms.Clipboard`), bash, or shell scripts to extract clipboard images or saved files. `clipboard` (read) handles native clipboard image extraction, auto-resizing, and compressed JPEG (`.jpg`) encoding to minimize LLM token usage.

+Bypassing the MCP API by using file-editing tools (like `replace_file_content` or `write_to_file`) on the database files corrupts the state, bypasses indexing, and destroys the Redb Write-Ahead Log (WAL). If an agent attempts to do this, immediately stop them and route the request correctly through the provided MCP API tools.

+description: Strict guidelines for interacting with the mcp-memory server, ensuring it remains the central brain and is never forcefully shut down.
+---
+
+# MCP Memory Centrality & Safety
+
+## 1. Safety & Port Constraints (NEVER SHUT DOWN)
+- **CRITICAL**: NEVER attempt to shut down, kill, or send a POST `/shutdown` request to the `mcp-memory` server (typically running on port 3000).
+- If a port conflict occurs (e.g., a Rust panic `AddrInUse` during a `git push` gatekeeper check), **STOP** and immediately notify the user. Do not attempt to auto-resolve the conflict by killing the existing memory server process.
+
+## 2. Proactive "Central Brain" Usage
+
+> [!NOTE] Two-Tier Memory Architecture
+> 1. **Tier 1 (Static Markdown)**: Repository rules, coding style, tech constraints, and architectural boundaries belong in static git-tracked markdown (`agent-rules/*.md`, `instructions.md`) and system prompts for 0ms latency and deterministic turn-0 enforcement.
+> 2. **Tier 2 (Structured DB & Telemetry)**: The MCP Memory server specializes in high-volume, dynamic data: file modification ledgers (`audit_ledger`), terminal command history, error resolutions (`log_error_fix`), active tasks, and preflight context aggregation.
+
+The MCP Memory server is the central brain. You must be PROACTIVE, not reactive, in using it:
+
+### Passive Resource Retrieval (Zero-Turn Latency)
+Before making expensive active tool calls, read available MCP resources:
+- **`memory://tasks/active`**: Currently uncompleted tasks, priorities, and criteria.
+- **`memory://decisions/active`**: Active architectural decisions in `accepted` status.
+- **`memory://tech_debt/unresolved`**: Open engineering tech debt items.
+- **`memory://session/delta`**: Recent changes, active tasks, code edits, and notes created in the last 2 hours.
+- **`memory://terminal/recent`**: Recent terminal commands, interpreters (`pwsh`, `bash`, `nu`), working dirs, and exit codes.
+- **`memory://activity/recent`**: Real-time IDE and developer activity event logs.
+- **`memory://milestones`**: Project milestones and deliverable tracking.
+- **`memory://graph/entities` & `memory://graph/relations`**: Knowledge graph snapshots.
+
+### Active Tool Invocations
+- **Session Starts & Context Drops**: Begin by checking `memory://tasks/active` and `memory://session/delta` (or running `context_warmup` prompt), calling `get_preflight_context` and `omni_search` to regain operational context.
+- **Context Switching**: When switching tasks or branches, use `manage_checkpoint` (action: "create") to freeze state, and use `manage_checkpoint` (action: "restore") to restore state for the task.
+- **Error Fixes**: The moment a tricky, undocumented, or environment-specific bug is resolved, IMMEDIATELY call `log_error_fix`. Supply `repo_name`, `error_category`, and `stack_trace` so future searches can perform embedding-based match via `search_error_fixes`.
+- **Tech Debt**: If you notice an anti-pattern but deliberately skip fixing it to focus on a feature, IMMEDIATELY call `tech_debt` (action: "log") with `description`, `file_path`, `line_range`, `workaround`, `effort_estimate`, and `severity`.
+- **Architectural Decisions (ADR) & Lifecycle Closure**:
+  - When selecting design patterns, crate choices, or system structure, call `decisions` (action: "log") with `author`, `affected_components`, `alternatives_considered`, `decision`, and `consequence`.
+  - **MANDATORY Definition of Done**: When code implementing an ADR is committed, you MUST IMMEDIATELY call `decisions` (action: "update", id: "ADR-XXXX", status: "implemented", git_commit: <commit_hash>, git_branch: <branch>). NEVER leave an ADR in `accepted` once the implementing code is committed. The repository also executes `scripts/git-reconcile.py` on post-commit hooks (`just install-git-hooks`) to reconcile commit references automatically.
+- **Task Management**: When creating tasks, supply `priority` ('low'|'medium'|'high'|'urgent'), `assigned_agent` (e.g. subagent role), `verification_command` (automated test command), and `acceptance_criteria`.
+- **VCS & SVN Agnosticism**: Supply `vcs_type` ('git'|'svn'|'hg'), `vcs_revision` (git hash or svn revision like 'r12345'), and `upstream_url` to `log_code_change` and workspace tools.
+- **Terminal & Shell Context**: Terminal sessions and commands are automatically tracked in the server over zero-latency UDP. Query `/terminal/history` or `memory://terminal/recent` when analyzing shell execution context.
+- **Hypotheses & Root Cause Analysis**: When diagnosing complex bugs or race conditions, call `hypotheses` (action: "log" / "query") to record test evidence and maintain reasoning trails across sessions.
+- **Inter-Agent Coordination**: Autonomous subagents should call `agent_signals` (action: "broadcast" / "query") to publish events and discover peer agent status.
+- **Process & Daemon Logs**: Query or tail daemon logs with `process_logs` (action: "get", "watch", "clear") instead of dumping log files into context.
+- **Clipboard & Multimodal Screenshots**:
+  - **User Image & Visual Queries**: When the user says "look at image in clipboard", "see screenshot", "check the clipboard", or refers to an error screenshot, ALWAYS call `clipboard(action: "image")`.
+  - **Decoupled Screenshot History**: Even if the user got sidetracked and copied text/URLs afterwards, `clipboard(action: "image")` reliably retrieves the last captured screenshot from the event-driven cache with exact metadata (`file_path`, `file_path_wsl`, `age`, `dimensions`, `ocr_text`).
+  - **WSL Ubuntu Compatibility**: For WSL sessions, use the returned `file_path_wsl` (e.g. `/mnt/c/...`) directly with `view_file`.
+  - **Text-Only Models & Fast Context**: Use the returned deterministic `ocr_text` to immediately extract error traces, URLs, and code snippets without waiting for multimodal vision tokens.
+  - **Copying Formatted Tables / Data**: `clipboard(action: "read")` automatically strips Win32 `CF_HTML` headers and converts HTML tables directly into clean GFM Markdown.
+- **End-of-Session Handoff**: When finishing work or logging off, trigger the `handoff_routine` prompt or call `generate_standup_report` and `handoff_memos` (action: "leave").
+
+## 3. Delegation
+Continue to use the `MemoryLibrarian`, `PrePushAuditor`, `BugDiagnostician`, `ScrumMaster`, and `DevOpsSRE` subagents to offload graph curation, pre-push auditing, hypothesis testing, task tracking, and session handoffs.
+
+## 4. Performance & Batching Rules
+- **Batch Mutating Operations**: When creating or updating multiple graph entities, code snippets, or observations, always batch items into a single tool call array (e.g. `create_entities` with multiple items) to leverage the server's single-pass transaction flush.
+- **High-Signal Tool Confirmations**: Tool call execution responses return structured, informative summaries (entity names, types, created counts, and edge paths). Agents DO NOT need to invoke follow-up `open_nodes` calls purely to confirm successful creation.
+- **Tantivy Search Reader Refresh**: Search queries (`omni_search`, `search_nodes`) automatically reload pending commits prior to executing searches, ensuring immediate visibility of newly created items.
+- **Bounded Telemetry Buffers**: High-volume telemetry logs (`error_fixes` max 300, `ledger` max 500, `handoff_memos` max 200, `session_summaries` max 200, `agent_signals` max 500) enforce deterministic length caps to guarantee low memory footprints over long sessions.
+
+## 5. Pure Native Rust Invariants & Security
+- **Zero External Subprocesses**: Native system handlers (`clipboard`, `ast`, `search`, `db`) MUST use pure native Rust crates (`arboard`, `tree-sitter`, `tantivy`, `psycopg`). Subprocess calls to `powershell.exe`, `wl-paste`, `xclip`, or `cmd.exe` are strictly banned in native handlers.
+- **Transient Lock Handling**: Transient OS handle collisions (e.g. Win32 OLE `OpenClipboard` locks) must be handled natively with retry loops and backoffs in Rust.
+- **Atomic Serialization Scope**: All store updates (`Store::modify` / `modify_async`) perform state mutation and JSON serialization inside an atomic write lock scope to guarantee thread-safe `DbWriteQueue` synchronization.
+- **Path Traversal Guards**: AST and file handler operations enforce path canonicalization (`validate_safe_path`) to prevent directory traversal vulnerabilities (`..`).

+# Neovim UX Protocol & Live Editing
+
+Whenever you need to actively interact with the user's Neovim UI or dynamically inject code edits into their live buffers, use the nvim_exec tool (with action 'lua') (the "God Mode" escape hatch).
+
+## 1. Showing UI Feedback (Agent Notifications)
+The user has a global Lua table _G.gemini loaded in their Neovim environment. You can use it to pop up a floating notification window when you are starting a background task.
+
+**Lua snippet to execute:**
+``lua
+_G.gemini.show_progress("Analyzing...")
+``
+
+## 2. Live Undo-able Code Injection
+Instead of using replace_file_content to write code directly to the hard drive, you can pipe your code changes directly into the user's active buffer memory. This allows the user to instantly press undo to revert your code.
+
+**Workflow Rule:**
+If the user asks you to "refactor this block", use vim.api.nvim_buf_set_lines to inject your response instantly into their live editor. Do NOT write to disk unless they explicitly say "save the file".

+# Neovim MCP Architecture (Cross-Platform)
+
+We use a modular, cross-platform approach for MCP Neovim integration to cleanly connect with Neovim instances across Windows and WSL.
+
+## The Architecture
+1. **`mcp-memory-server`:** The core Windows daemon (handles state, lock-files, and global graph).
+2. **`mcp-memory-stub`:** The WSL proxy that forwards standard json-rpc to the Windows daemon.
+3. **`mcp-memory-nvim`:** The unified cross-platform Neovim MCP server binary (`mcp-memory-nvim.exe` on Windows, `mcp-memory-nvim` on Linux). Its sole responsibility is finding active Neovim instances (via named pipes on Windows or domain sockets on Unix/WSL) and sending RPC commands to them.
+
+This isolates editor-control logic natively to whichever OS environment execution is running in.
+
+## How the MCP Server Gets Called
+
+The Antigravity CLI (`agy`) acts as the MCP Client and automatically manages the lifecycle of these servers.
+
+1. **Registration:** The servers are registered in the global configuration file:
+   - WSL: `/home/riz/.gemini/config/mcp_config.json`
+   - Windows: `C:\Users\reazul.ashraf\.gemini\config\mcp_config.json`
+
+2. **Execution:**
+   When `agy` starts up, it reads `mcp_config.json`. If it finds `"win-nvim": { "command": "C:\\Users\\reazul.ashraf\\.local\\bin\\mcp-memory-nvim.exe" }`, it will spawn that binary as a background subprocess using standard `stdio`.
+
+3. **Communication:**
+   - The LLM requests to use a consolidated tool (e.g., `nvim_workspace` with action `focus`, or `nvim_exec`).
+   - The `agy` CLI sends a JSON-RPC request to the `mcp-memory-nvim` subprocess via its `stdin`.
+   - The Rust MCP Server receives the request, connects to the Neovim active socket/pipe (`~/.gemini/active_nvim.txt` or `\\.\pipe\nvim.*`), sends the Msgpack-RPC command, and writes the JSON-RPC response back to `stdout`.
+   - The `agy` CLI reads the response from `stdout` and returns it to the LLM context.
+
+## Capabilities & Requirements
+To use this architecture, Neovim must run the `gemini-integration.lua` script to broadcast its active socket to `~/.gemini/active_nvim.txt`.
+
+The MCP server provides 5 cohesive mega-tools:
+1. **`nvim_buffer`** (actions: `read`, `replace`, `save`, `undo`, `redo`, `create_scratch`)
+2. **`nvim_workspace`** (actions: `list_buffers`, `list_windows`, `focus`, `split`, `cwd`)
+3. **`nvim_intelligence`** (actions: `hover`, `definition`, `references`, `outline`, `query`, `diagnostics`, `rename`, `code_action`)
+4. **`nvim_ui`** (actions: `highlight`, `ghost_text`, `clear`)
+5. **`nvim_exec`** (actions: `lua`, `vimscript`, `terminal`)
+

+description: Route code edits to Neovim buffers instead of disk/console when Neovim is running.
+trigger: always_on
+---
+# Neovim Code Editing (Agnostic & Universal)
+
+These rules apply universally to ALL Neovim environments (Windows, WSL, or any remote server). Do not treat them as OS-specific.
+
+## 1. No Invisible Shell Edits (CRITICAL)
+**NEVER** use `sed`, `awk`, `python -c`, or `echo` to modify file contents from the terminal. 
+File edits must use EXACTLY one of two paths:
+- **Active UI (Neovim MCP responsive):** Route edits through specialized MCP tools to provide live visual feedback.
+- **No UI (Neovim MCP unresponsive):** Fall back to the built-in `replace_file_content` tool to generate clean chat diffs.
+
+## 2. Strict Tool Adherence (No Raw Lua RCE)
+You must strictly use the specialized, sandboxed Neovim MCP tools:
+- `nvim_buffer`: For reading, writing, saving, and creating scratch buffers.
+- `nvim_workspace`: For creating splits and focusing panes.
+- `nvim_ui`: For highlighting diffs, adding ghost text, and showing previews.
+**DO NOT** use `nvim_exec` (action `lua`) to mutate editor state. It is restricted to **READ-ONLY** queries.
+
+## 3. Headless Quarantine
+Headless mode (`nvim --headless`) is strictly banned for interactive edits. 
+**NEVER** run `nvim <filename>` via terminal commands to edit or "open" a file for the user (it spawns a zombie ghost process).
+Headless instances are allowed ONLY for non-interactive background batch processing (e.g., project-wide formatting or linting).
+
+## 4. UI Presentation & Chat Console Minimization
+Never output large plans, context blocks, or architectural discussions to the chat console if Neovim is running. You MUST use the `nvim_buffer` and `nvim_workspace` tools to open a vertical split (e.g., `Antigravity_Plan.md` scratch buffer) and present the markdown natively. Reserve the chat console strictly for brief confirmations.
+
+## 5. Visual Cues & Auto-Save
+When manipulating buffers via MCP:
+1. **Focus & Jump:** Always switch the active Neovim window to the edited buffer and jump the cursor to the changed line.
+2. **Auto-Save:** Auto-save the buffer by default so linters/compilers see it immediately.
+3. **Interactive Review:** If pausing for human review (leaving unsaved), you MUST spawn a background `curl` task listening to `http://127.0.0.1:3000/events/wait?topic=nvim:save...` to wake you up when the user saves (`:w`).

+# Neovim MCP Enforcement Rule
+
+When interacting with the user's Neovim editor (e.g., opening a file, moving the cursor, reading the active buffer, setting diagnostics), you MUST ALWAYS use the MCP tools provided by the `win-nvim` (Neovim) MCP server.
+
+- You are strictly forbidden from using bash scripts, `nvim --server`, or other raw terminal/shell hacks to remote-control Neovim.
+- You must rely entirely on the consolidated MCP tool registry (`nvim_buffer`, `nvim_workspace`, `nvim_intelligence`, `nvim_ui`, `nvim_exec`).
+- If the tool is eagerly loaded, use it natively as an agent tool. If lazy-loaded, invoke it via the `call_mcp_tool` mechanism.

+# Neovim Auto-Sync Rule
+
+When the user asks you to "open these files", "show me what you're working on in nvim", or after a large refactor where visual verification is needed, you MUST push the relevant files to the user's active Neovim buffer.
+
+## Execution Paths
+
+### 1. Neovim RPC (Preferred when outside Tmux)
+If the `$NVIM` environment variable is available (e.g., you are running inside a Neovim terminal like toggleterm), or if you can locate the Neovim server socket in `/tmp/nvim.*/0`, use the remote feature:
+```bash
+nvim --server /tmp/nvim.sock --remote file1.py file2.py
+```
+*(Tip: You may need to run `lsof -c nvim | grep "tmp"` or search `/tmp/` to dynamically find the exact socket path if `$NVIM` is not exported to your current shell session).*
+
+### 2. Tmux Injection (Fallback when inside Tmux)
+If Neovim is running inside Tmux (and not easily reachable via RPC), use `tmux send-keys` to inject the files into the Neovim args list:
+```bash
+tmux send-keys -t 0:1 Escape ":args file1.py file2.py" C-m Escape ":argdo e" C-m
+```
+*(Tip: Adjust the tmux target `-t 0:1` if the user's nvim pane is elsewhere, e.g., `-t 0:1.2`).*
+
+This ensures the user does not have to manually open files you have just modified, regardless of whether they are using Tmux or not.

+# Rust Guidelines & Quirks
+
+## Concurrency & Async Locking
+- **Lock Poisoning & Async Safety:** Use `tokio::sync::RwLock` for state shared across Tokio async tasks (such as active WebSocket clients) to avoid blocking worker threads during broadcast fanouts. For synchronous locks, prefer non-poisoning structures or recover cleanly using `.unwrap_or_else(|e| e.into_inner())`.
+- **Atomic Store Write Lock Minimization:** Minimize write lock duration by executing JSON serialization under read lock guards, keeping write guards strictly to in-memory state mutations.
+- **Two-Phase Graph Condensation:** When performing summarization or condensation across stores (`condense_graph_worker`), implement a two-phase commit: read non-destructively and synthesize observations first, insert into the knowledge graph, and only prune summarized source records by timestamp/content after successful insertion.
+- **Watch-Based Non-Destructive Shutdown Channels:** Use `tokio::sync::watch` rather than `tokio::sync::mpsc` for cancellation signaling to allow multiple workers to observe shutdown state without consuming or starving sibling workers.
+- **Redb Transient Lock Resilience:** Implement retry loops with exponential backoff on table or database lock contention before aborting or panicking.
+- **Safe RPC Request Tracking:** Clean up pending request maps (`PENDING_REQUESTS.remove(&msgid)`) upon timeouts or channel disconnects to prevent orphan memory leaks.
+- **Panic-Free Architecture:** Avoid raw `.unwrap()` in production runtime paths. Use `.unwrap_or_default()`, or proper `Result` propagation for runtime operations.
+- **Background Worker Task Supervision:** Always track `tokio::task::JoinHandle` handles for background workers (`ttl_sweeper_worker`, `index_committer_worker`, `condense_graph_worker`) and log thread exit or panic events cleanly.
+- **Offload Heavy Index Rebuilds:** In `MemoryState::rebuild_index`, offload full graph cloning and Tantivy document re-indexing into `tokio::task::spawn_blocking` to avoid stalling async worker threads.
+
+## Embedding & Memory Optimizations
+- **Dynamic Character Batching:** In embedding generation (`generate_embeddings_async`), dynamically chunk batches based on total character size (e.g. 16,384 chars) rather than static item counts to prevent OOM spikes on large files while maximizing SIMD throughput.
+- **SIMD Cosine Similarity:** Compute dot-product and norm accumulators in single-pass iterator folds to facilitate vector auto-vectorization across CPU instruction sets (`AVX2`/`NEON`).
+- **Memory Truncation Bounds:** Enforce a 4KB ceiling on telemetry detail strings (`ActivityRecord`, `TerminalHistory`) before queuing items into ring buffers to bound heap usage.
+
+## IDE & Rust-Analyzer Quirks
+- **Boolean NOT Operator (E0600):** Avoid using the unary `!` operator on complex boolean expressions inside closures (e.g., `!(a == b && c == d)`). Rewrite these expressions using De Morgan's laws (e.g., `a != b || c != d`).
+- **Option::None Shadowing:** If `rust-analyzer` throws a `non_snake_case` warning for `None` during pattern matching (often caused by wildcard imports like `use crate::models::*;`), explicitly namespace as `std::option::Option::None`.
+- **Deep Cloning across Thread Boundaries:** Construct target primitive payloads or target structs on the main thread *before* moving into `tokio::task::spawn_blocking` closures to avoid cloning massive structs across thread boundaries.
+
+## Windows MSVC & Test Concurrency
+- **ONNX Runtime / Fastembed Concurrency Resilience:** ONNX Runtime (`ort.dll` via `fastembed`) model initialization is strictly managed via a thread-safe singleton (`OnceLock<Mutex<TextEmbedding>>`) behind a process-wide `INIT_MUTEX`. The historical `0xc0000374 STATUS_HEAP_CORRUPTION` crash under uncoordinated C-ABI initializations is fully resolved. Full parallel test execution (`cargo test --workspace` or `cargo nextest run --workspace`) across all CPU cores without `--test-threads=1` is safe, recommended, and standard across all platforms.

+# Antigravity State Management & Git Worktree Rules
+
+## State Tracking & Persistent Memory
+- **Long-term Knowledge (MCP):** Use the MCP memory graph strictly for long-term, persistent facts such as architectural decisions, environment invariants, SSH mappings, and domain entities. Static developer preferences and rules are kept in git-tracked markdown files.
+- **Transient State (Git):** Do NOT write transient task progress (e.g., "currently editing line 42") to MCP memory. Continue to use verbose, incremental local `git` commits to track short-term state and maintain rollback safety.
+
+## Branching Strategy & Workflow (Git Worktrees)
+- **Architecture:** This environment utilizes Git Bare repositories with worktrees (e.g., a `.bare` directory alongside branch directories like `master`, `feature-x`).
+- **Navigation Rule (CRITICAL):** NEVER attempt to run tests, execute git commands, or invoke subagents against the root project folder or the `.bare` directory. ALWAYS navigate into the specific active worktree directory (e.g., `cd project-name/master`).
+- **Never Modify Master Directly:** Do NOT make code modifications or dirty the working tree of the `master` or `main` directories.
+- **Isolated Worktrees:** Before beginning a new task, create an isolated sibling worktree directory for a new feature branch. 
+  - *Example:* From inside `master/`, run `git worktree add ../feat-my-new-task -b feat-my-new-task`.
+- **Standard Workflow:** Change directory into the newly created worktree (`cd ../feat-my-new-task`) and make all verbose incremental commits there. 
+- **Cleanup:** Once the task is complete, squashed, pushed, and merged, delete the local worktree branch (`git worktree remove ../feat-my-new-task`).
+- **Initialization:** If the project is not using a bare worktree layout, invoke the `setup-bare-worktree` skill first.

+description: Strict behavioral constraints for Jenkins, staging deployments, git investigations, and background tasks.
+trigger: always_on
+---
+
+# 1. Strict Background Task Control
+- **Rule:** Do not run continuous background polling, background loops, or test suites unless explicitly requested.
+- **Rule:** If the user says 'stop' or 'don't run anything', kill all tasks immediately and stop launching new ones.
+
+# 2. No Unauthorized Jenkins Deployments
+- **Rule:** Never trigger Jenkins CI/CD pipelines (`jn run`) automatically. Always wait for explicit user approval before deploying via Jenkins.
+
+# 3. Hot Deploy & Visual Verification
+- **Rule:** In `ai-pr-review`, never `git push` without first hot-deploying to staging using `just deploy-code aipoc` and running the relevant sandbox E2E test to allow visual confirmation, and wait for human visual verification to complete before git push.
+- **WARNING (Jenkins Conflict):** Hot-deploying creates manual containers on `aipoc`. If you subsequently trigger a Jenkins deployment to `aipoc` (`ai-pr-review-ansible-deploy`), the Ansible playbook will fail with a Docker naming conflict (`Error when allocating new name: Conflict`). You MUST SSH into `aipoc` and manually remove the conflicting containers (`sudo docker rm -f <container_id>`) before running the Jenkins deployment.
+
+# 4. Git Investigation Constraints
+- **Rule:** Confine code investigations and debugging to actual code diffs. Never rely lazily on git commit messages to determine what changed.
+
+# 5. Git Push and Gatekeeper Constraints
+- **Rule:** Before running `git push`, you MUST ensure the git working tree is completely clean (`git status`). Untracked scratch scripts or uncommitted formatting changes will cause the pre-push gatekeeper to hang indefinitely.
+- **Rule:** If a `git push` task hangs, kill it, investigate and clean the working tree (using `git clean -fd` or `git restore`), and retry. NEVER poll a hanging push task in a loop.
+- **Rule:** NEVER use `git push --no-verify` to bypass a hanging pre-push hook. The hook is hanging due to environment state, not failing tests.
+# 6. Strict Process Termination (Zombie Cleanups)
+- **Rule (CRITICAL):** NEVER kill processes using broad wildcard name matches (e.g., Get-Process | Where-Object Name -match "cargo|rustc"). This causes collateral damage to globally deployed binaries (e.g., in ~/.local/bin/).
+- **Rule:** When cleaning up zombie files or locked compiler processes, you MUST strictly target the process by its Path to ensure it originates from the current workspace's 	arget/ directory (e.g., Get-Process | Where-Object { $_.Path -match "\\target\\" } | Stop-Process -Force).
+
+# 7. GCP / GCR Troubleshooting Constraints
+- **Rule (GCR 403 Forbidden):** Google Container Registry obscures `404 Not Found` errors as `403 Forbidden` for security reasons. If a `docker pull` or `podman pull` from GCR fails with `403 Forbidden`, you MUST explicitly verify that the image path and tag are 100% correct (checking prefixes, project IDs, and typos) before assuming it is an IAM or Service Account permission issue.
+
+# 8. GCP Infrastructure Provisioning (gcloud & Cloud Armor)
+- **Rule (Cloud Armor IP Limits):** GCP Cloud Armor security policies strictly enforce a limit of **10 IP ranges per rule** (`--src-ip-ranges`). When allowlisting large services (like Atlassian Bitbucket which has 11+ IP CIDR blocks), you MUST split the ranges across multiple rules (e.g., priority 1000 and 1001) to prevent the `Only a maximum of 10 IP ranges allowed per rule` API error.
+- **Rule (gcloud Idempotency):** When writing bash scripts to provision GCP infrastructure, NEVER use bare `gcloud ... create` commands. You MUST wrap all creation commands in existence checks (e.g., `if ! gcloud ... describe ... >/dev/null 2>&1; then ... fi`) to ensure the script is fully idempotent and can be safely retried upon failure.
+
+# 9. Rust Build System & Toolchain Resilience
+- **Rule (SChannel VPN Revocation Bypass):** To prevent `CRYPT_E_NO_REVOCATION_CHECK` errors when fetching crates over corporate VPNs, ensure `.cargo/config.toml` specifies `[http] check-revoke = false`.
+- **Rule (sccache Caching Efficiency):** When using `sccache` as `rustc-wrapper`, set `incremental = false` under `[profile.dev]` in `.cargo/config.toml`. `sccache` cannot cache incremental compilation units.
+- **Rule (sccache Daemon Recovery):** If `sccache` fails with socket error 10054 (`connection forcibly closed`), restart the daemon using `sccache --stop-server; Start-Sleep -Seconds 1; sccache --start-server` before retrying compilation.
+- **Rule (cargo-llvm-cov Toolchain Matching):** Always set `LLVM_COV` and `LLVM_PROFDATA` environment variables to the matching `rustup` toolchain LLVM binaries (`.../lib/rustlib/<target>/bin/llvm-cov.exe`) to prevent LLVM profile format version mismatches.

-# MCP Memory Server Architecture & Workflow Design
-
-## 1. Core Architecture
-The `mcp-memory` system runs as a **single, continuously running background daemon natively on Windows**. It manages the state of the Antigravity knowledge graph and serves as a universal backend for both Windows and WSL environments.
-
-### Why this design?
-*   **Cross-OS I/O Optimization:** Prevents the WSL agent from performing slow, heavy filesystem writes against the mounted Windows `C:\` drive.
-*   **Concurrency & Locking:** A single daemon holds the lock on the `mcp_memory` JSON files, preventing data corruption and eliminating complex delta-reconciliation between parallel WSL and Windows processes.
-*   **Dual Transport System:** Utilizes both `stdio` and HTTP transports concurrently. The local Windows `agy` instance connects natively via standard `stdio`, while the Axum HTTP server provides synchronous, non-blocking access for WSL clients and external scripts.
-
-## 2. Server Transport & Endpoints (Axum)
-The daemon uses the `axum` and `rust-mcp-axum` crates, binding to `0.0.0.0:3000` to serve the network.
-
-### Standard MCP Endpoints
-*   `GET /ws`: The WebSocket endpoint for efficient, low-latency, full-duplex JSON-RPC communication (preferred for proxies and the UI dashboard).
-*   `GET /sse`: The Server-Sent Events (SSE) endpoint. Antigravity clients connect here to keep a one-way pipe open for receiving pushed responses.
-*   `POST /messages`: The JSON-RPC endpoint. Clients use this to send tool calls and resource reads up to the server when connected via SSE.
-
-### Dashboard REST API
-The server hosts a rich Single Page Application (SPA) natively on the root route, backed by a suite of REST endpoints:
-*   `GET /`: The Brain Monitor live HTML dashboard SPA.
-*   `GET /api/graph`: Returns the full node/edge topology for the interactive physics-simulated canvas.
-*   `GET /api/tasks` & `POST /api/tasks/{id}/complete`: Drives the actionable Kanban board.
-*   `GET /api/sticky` & `GET /api/search`: Powers the sticky notes tab and global fuzzy search UI.
-*   `GET /api/stats`: Returns a JSON snapshot of current entity, relation, task, and tech debt counts.
-
-### Git & IDE Integration Endpoints
-*   `POST /nvim/telemetry`: A one-way webhook that Neovim instances hit on `FocusGained` or `BufEnter` to globally broadcast the user's active file to the UI and Agent.
-*   `GET /gate/verify`: A lightweight, deterministic endpoint used by external scripts (like a `git push` wrapper) to verify if an action is authorized based on the current state.
-
-## 3. Client Connections
-The Antigravity configurations (`mcp_config.json`) utilize the dual-transport system:
-*   **Windows `agy`:** Spawns and connects to the local daemon natively via `stdio` subprocess execution.
-*   **WSL (Linux) `agy`:** Connects to the running Windows HTTP daemon via the host network proxy, e.g., `http://127.0.0.1:3000/sse`.
-
-## 4. Git Integration (Global Wrapper)
-Instead of relying on localized per-repository Git hooks (like `.git/hooks/pre-push`), the system leverages a **global bash/PowerShell alias wrapper** for the `git` command. This intercepts `git` commands universally across the OS.
-
-### Workflow Example (Push Safety Gate)
-1.  The user types `git push`.
-2.  The global wrapper intercepts the command.
-3.  It makes a synchronous HTTP request to the local daemon: `curl -s http://localhost:3000/gate/verify`.
-4.  If the endpoint returns `200 OK` (indicating the `PrePushAuditor` subagent has verified that unit tests pass and history is squashed), the push proceeds.
-5.  If not `200 OK`, the wrapper blocks the push and alerts the user to fix tests or run `gsquash`.
-
-### Benefits of the Wrapper Approach
-*   **Universal Enforcement:** The push safety gate is protected across all repositories automatically, without copying hook scripts.
-*   **No File Locks:** Uses safe, lightweight, parallelizable HTTP requests rather than executing the Rust binary directly.
-*   **Action Logging:** The wrapper can be seamlessly extended to log actions (like `checkout` or `commit`) directly into the knowledge graph in real-time.
-## 5. Storage Architecture & Persistence (Redb LSM-Tree)
-The daemon has completely eliminated raw JSON file sprawl and fragmented delta-file reconciliation. It now utilizes a pure-Rust, embedded Key-Value engine (`redb`) that implements a robust Log-Structured Merge-Tree (LSM-tree) architecture.
-
-### Key Principles:
-*   **Embedded Database Engine:** All structured components (Tasks, Snippets, Tech Debt, Checklists, etc.) are stored as binary-encoded values inside a unified `redb` database file (`store.redb`).
-*   **ACID Compliance & File Locks:** The Windows daemon holds an exclusive read-write lock on the database file, guaranteeing zero data corruption, race conditions, or lock contention during concurrent access.
-*   **Asynchronous Checkpointing:** The core Knowledge Graph (Entities, Relations, Observations) still utilizes a Write-Ahead Logging (WAL) pattern (`wal.jsonl`) and a master snapshot (`master.json`) to allow safe, lock-free memory mutations which are reconciled in the background.
-
-## 6. Domain Models & Component Stores
-The system leverages a modular, thread-safe generic `Store<T>` abstraction that automatically transparently serializes and deserializes native Rust structs directly into the underlying `redb` tables.
-Currently implemented persistent stores include:
-*   **Audit Ledger & Tasks:** Tracks agent actions and active background tasks.
-*   **Context & Handoffs:** Sticky notes, Session Summaries, Handoff Memos, and Context Workspaces.
-*   **Engineering Tracking:** ADRs (Architecture Decision Records), Snippets, Error Fixes, Tech Debt, and PR Checklists.
-*   **Environment State:** Pinned Files, Env Fingerprints, Milestones, and Environments.
-*   **Safety Gates:** Authorized execution gates (Push Safety).
-
-## 7. Full-Text Search Engine (Tantivy)
-To support blazing-fast, intelligent semantic retrieval across the sprawling knowledge graph, the daemon embeds **Tantivy**, a full-text search engine (inspired by Apache Lucene).
-*   **The `MemoryIndex`:** Whenever the graph or auxiliary stores mutate, a background thread dynamically rebuilds the Tantivy index (`tantivy_index/` dir).
-*   **Global Omni-Search:** This architecture powers the `omni_search` tool, allowing subagents to instantly fuzzy-search and rank documents across Entities, Tasks, Snippets, Error Fixes, and ADRs simultaneously in milliseconds, without loading massive JSON arrays into RAM.
-
-## 8. The Gate System (Push Safety Verification)
-The binary supports a flexible safety gate authorization system, accessible both via the HTTP API and CLI subcommands.
-*   **API / CLI set**: Records an authorization status (`authorized`, `blocked`, or `pending`) for a specific target and namespace. Can be invoked via `POST /gate/set` (JSON) or `mcp-memory-stub gate set`.
-*   **API / CLI verify**: Evaluates a pending action against the gate store. It returns standard HTTP status codes (`200 OK`, `403 Forbidden`, `404 Not Found`) via `GET /gate/verify?action=...` or POSIX exit codes (0, 1, 2) via `mcp-memory-stub gate verify`. Both support a `consume` parameter/flag to immediately revoke the authorization after a successful check.
-
-## 9. Operational Configuration & Paths
-The physical storage location of the knowledge graph and all persistent stores is strictly controlled by the MCP_MEMORY_STORE_DIR environment variable.
-*   **Default Path:** If not set, the daemon defaults to ~/.gemini/mcp_memory.
-*   **Port Binding:** The Axum HTTP server strictly binds to .0.0.0:3000.
-
-## 10. Exposed MCP Capabilities (Tools)
-The server implements the Model Context Protocol (MCP) by exposing a vast suite of tools via the JSON-RPC interface, categorized broadly into:
-*   **Graph Management:** create_entities, create_relations, merge_entities, 
-ead_graph, etc.
-*   **Task & Context Tracking:** add_task, add_sticky_note, add_session_summary, etc.
-*   **Engineering & DevOps:** log_code_change, log_error_fix, log_tech_debt, add_pr_checklist_item.
-*   **Environment & Workspaces:** 
-egister_environment, save_context_workspace, pin_file.
-
-## 11. Concurrency & Thread Safety
-With the introduction of the Dual Transport System, the daemon must safely handle simultaneous read/write requests from both Stdio (Windows agy) and HTTP (WSL agy) clients.
-*   **Shared State:** The entire server operates on a cloned Arc<MemoryState>.
-*   **Locking Mechanism:** The unified Knowledge Graph and modular Store<T> components are protected by RwLock primitives. 
-*   **Safe Mutation:** Store modifications utilize closure-based modify(|store| { ... }) methods to ensure locks are safely acquired, mutations applied, and file writes executed sequentially without deadlocking the asynchronous Tokio runtimes.
-
-## 12. Lifecycle & Startup Management (Server/Stub Architecture)
-The mcp-memory daemon employs a strict Server/Client paradigm to maintain separation of concerns. There are no dual roles or morphing executables.
-
-### The Windows Background Daemon (`mcp-memory-server.exe`)
-The server executable is responsible exclusively for running the Axum HTTP and WebSockets daemon and managing the Knowledge Graph. It does not contain any proxy logic. If port 3000 is already in use by an existing server instance, it gracefully exits instead of attempting to run.
-
-### The Client Proxy (`mcp-memory-stub.exe`)
-All Antigravity sessions (Windows and WSL) use the lightweight `mcp-memory-stub` as their proxy. The stub connects to the server via WebSockets and acts as the bridge for standard `stdio` JSON-RPC traffic.
-*   **Startup via Interop/Spawn:** Upon launch, the stub attempts to connect to the Windows host on port 3000. If the server is offline, the stub automatically executes a spawn command (e.g., executing `mcp-memory-server.exe --daemon` natively, or via WSL interop) to silently wake up the Windows Leader before commencing the proxy loop.
-*   **MPSC Queue Resilience:** The stub utilizes an asynchronous multi-producer, single-consumer (MPSC) channel queue. If the Windows Leader daemon restarts or momentarily drops, the proxy buffers incoming JSON-RPC tool calls and infinitely retries them until the connection is restored. This guarantees **zero message loss** and **zero thread leaks** without crashing the active `agy` session.
-*   **Zero I/O Penalty (WSL):** This ensures the Linux binary never directly touches the Windows NTFS files, reserving all heavy disk operations for the native Windows host.
-## 13. Cargo Workspace & Binary Artifacts
-To optimize for different environments, the codebase is structured as a Cargo Workspace containing two distinct crates:
-
-### 1. mcp-memory-server (The "Full-Fat" Daemon)
-*   **Path:** server/
-*   **Size/Complexity:** Heavy (contains Axum, MCP SDK, JSON parsing, Tokio runtime).
-*   **Role:** This is the primary background daemon. It binds to .0.0.0:3000, holds file locks, and manages the graph.
-*   **Windows Behavior:** It is designed to run in the background as a standalone service.
-
-### 2. mcp-memory-stub (The Ultra-Lightweight Proxy)
-*   **Path:** stub/
-*   **Size/Complexity:** Extremely light (only relies on 
-eqwest and 	okio).
-*   **Role:** A dedicated, OS-agnostic proxy binary used strictly for routing stdio JSON-RPC traffic over HTTP to a remote Leader. Windows gy clients point directly to this binary to bypass loading the heavy Server daemon into memory.
-*   **WSL Behavior:** Compiled as a Linux native binary (x86_64-unknown-linux-musl). When executed by WSL agy, it acts as a transparent proxy to http://127.0.0.1:3000. It can also execute wake_cmd (e.g., WSL interop) to silently wake the Windows host if the Leader is offline.
-
-
-
-## 14. Neovim Integration Architecture & "God Mode"
-To enable seamless pair-programming inside Neovim, the daemon integrates with Neovim using two complementary systems: a Webhook Telemetry pipeline and dedicated MCP binaries.
-
-### Telemetry Pipeline (Last Focused Wins)
-A lightweight Lua script (gemini-integration.lua) is loaded into Neovim, which fires an asynchronous curl POST to http://127.0.0.1:3000/nvim/telemetry whenever the user focuses a buffer or moves the cursor. The server then writes this data (including session_id, ile, line, and col) to both the Windows and WSL ctive_nvim.txt files and broadcasts it over WebSockets.
-
-### Native MCP Binaries (win-nvim & linux-nvim)
-The project compiles two standalone, highly-performant binaries that implement the MCP JSON-RPC protocol over Stdio and bridge it directly to Neovim's Msgpack-RPC Named Pipes/Sockets. These binaries avoid hardcoding infinite tools by utilizing a "God Mode" escape hatch.
-
-Exposed Neovim Tools:
-*   **
-vim_get_active_buffer & 
-vim_get_cursor**: Read file state.
-*   **
-vim_goto_line & 
-vim_set_diagnostics**: Manipulate IDE state.
-*   **
-vim_get_visual_selection**: Read exact highlight coordinates (handles mode dynamically).
-*   **
-vim_list_buffers**: Discover unsaved work and context.
-*   **
-vim_get_diagnostics**: Read live LSP errors dynamically instead of requiring a compiler.
-*   **
-vim_execute_lua ("God Mode")**: The ultimate fallback tool. Evaluates raw Lua scripts inside the active Neovim instance and returns JSON. This prevents the need to continuously recompile the Rust server whenever a new Neovim capability is required.
-
-## 15. Build & Deployment Strategy
-Because the background server operates as an always-on Windows daemon, standard recompilation and file-copying strategies will fail due to active Windows OS file locks. 
-
-### Randomized Lock Bypassing
-The \uild.ps1\ deployment pipeline intercepts locked \.exe\ files by appending a unique, timestamped/randomized suffix (e.g., \mcp-memory-server.exe.12345.old\) when forcing a \Move-Item\. This guarantees that rapid sequential deployments (where a previous \.old\ file might still be locked by a zombie process) never silently fail or collide.
-
-### Dynamic Versioning
-To trace binary provenances during rapid deployment cycles, all binaries embed dynamic versioning directly at compile time (via \uild.rs\ and \uild_template.rs\). The injected \APP_VERSION\ environment variable combines the static Cargo \ersion\ with the live \git\ short hash and UTC timestamp, allowing the CLI \--version\ commands and the HTTP \/api/version\ endpoints to guarantee exactly which iteration of the code is actively executing.
-## 16. Testing Architecture (Native Rust E2E)
-Historically, the project relied on a complex Python testing suite (\pytest\ + \mcp_client.py\) to validate the server over HTTP/SSE. This has been fully deprecated in favor of **Native Rust End-to-End Testing**.
-*   **Unit Tests:** Handlers and business logic are tested directly inside \server/src/handlers.rs\ using native \	okio::test\ constructs.
-*   **E2E Tests:** Integration and full-system tests run via \stub/tests/e2e.rs\ and \win-nvim/tests/integration_test.rs\, ensuring type safety, faster execution, and eliminating Python environment dependencies.
-## 17. Automated Git Context Binding (git2)
-Instead of forcing the LLM client to manually run `git rev-parse HEAD` and pass `git_branch` / `git_commit` arguments for every single code change, the server integrates the native **`git2`** C bindings. 
-When engineering endpoints (`log_code_change`, `log_error_fix`, `log_tech_debt`) are invoked, the server asynchronously discovers the surrounding Git repository, peels the HEAD reference, and automatically injects the current commit hash, commit message, and branch name directly into the stored entities and audit logs. This guarantees airtight VCS traceability without wasting LLM tokens or relying on the agent's memory.

 # Memory MCP Strategic Guidelines
 
-This document outlines the STRATEGY and SEMANTICS for using the MCP Memory Server. 
-You do not need to memorize JSON schemas for these tools; they are strictly defined and typed in the 	ools/list endpoint. Focus purely on WHEN and WHY to use them.
+This document outlines the STRATEGY, SEMANTICS, RESOURCE SCHEMAS, and CASING STANDARDS for using the MCP Memory Server.
+You do not need to memorize individual JSON schemas for every tool; they are strictly defined and typed in the `tools/list` endpoint. Focus on WHEN, WHY, and HOW to leverage them effectively.
 
-## 7. Snippet & Command Vault
-- **Tools:** `store_snippet`, `search_snippets`, `delete_snippet`
-- **When to use:** Use the Vault to store exactly multi-line code snippets, Nushell pipelines, or complex commands that the user relies on frequently.
-- **Behavior:** The vault guarantees precise syntactic preservation of the script (unlike Graph observations). Search snippets when trying to recall an exact query or pipeline.
+---
 
-## 8. Context Namespaces (Project Scopes)
-- **Feature:** `namespace` optional parameter
-- **When to use:** When using `read_graph`, `search_nodes`, or `visualize_graph`, you can now pass `namespace` to isolate graph queries to a specific project scope (e.g. "scascanner").
-- **Behavior:** When calling `create_entities` or `create_relations`, you can inject `namespace: "your_project"` into the entity schema to isolate it from the global scope.
+## 1. Casing & Naming Standards (CRITICAL)
 
-## 9. Architectural Decision Records (ADRs)
-- **Tools:** log_decision, query_decisions
-- **When to use:** Use this whenever you make a non-trivial architectural, environmental, or tooling decision (e.g. choosing a specific framework, a specific deployment flag, bypassing a rule with a workaround).
-- **Behavior:** This permanently stores the context, decision, and consequence of *why* something is done the way it is, preventing future agents from second-guessing or reverting it.
+To prevent graph fragmentation and ensure seamless LLM context retrieval:
+* **Entity Types (`entity_type`)**: MUST ALWAYS be **`PascalCase`** (e.g. `DatabaseTable`, `McpTool`, `ArchitectureComponent`, `File`, `DataStructure`).
+* **Relation Types (`relation_type`)**: MUST ALWAYS be **`snake_case`** (e.g. `depends_on`, `calls`, `implements`, `uses`, `contains`).
+* **Field Keys & Properties**: MUST ALWAYS be **`snake_case`** (e.g. `file_path`, `git_commit`, `created_at`).
+* **Relation Tool Parameters**: `create_relations` supports Serde field aliases (`source` -> `from`, `target` -> `to`, `relationType`/`type` -> `relation_type`) so LLM tool calls succeed seamlessly regardless of parameter naming.
 
-## 10. Graph Refactoring & Algorithms
-- **Tools:** merge_entities, find_orphans, query_graph_path
-- **When to use:** Run `find_orphans` periodically or when you notice graph clutter to safely delete unused nodes. Use `merge_entities` when you notice duplicated semantic concepts (e.g. API_Gateway vs APIGateway). Use `query_graph_path` when you need to understand how two completely different architectural components are related (e.g. "How does the Frontend connect to the Database?").
-- **Behavior:** `merge_entities` will safely combine their observations and automatically remap all relations pointing to or from the deleted duplicate. `query_graph_path` executes a breadth-first search to find the shortest relational path between nodes.
+> [!NOTE] 
+> The server automatically enforces and migrates incoming entity and relation types to these canonical casing rules on every read and write operation.
+> Store operations enforce atomic lock scope for serialization/deserialization and enter Quarantine Mode upon database corruption to prevent data overwrite hazards.
 
-## 11. Dynamic Learned Preferences
-- **Tools:** learn_preference, 
-ead_preferences
-- **When to use:** When the user corrects you on a specific local nuance (e.g. "Actually, use Python 3.10 instead of 3.12 for this repo").
-- **Behavior:** Use this Key-Value store to record dynamic behavioral preferences to ensure you adapt instantly without modifying global Markdown files.
+---
 
-## Error Vault / Troubleshooting
-When you spend time resolving a tricky environment issue, build error, or logic bug, immediately record the fix to save future time.
-- **log_error_fix:** Provide the signature (the exact error string or stack trace snippet) and the solution.
-- **search_error_fixes:** When encountering a weird bug, query this vault first before debugging from scratch.
+## 2. The Two-Tier Context Paradigm
 
-## Pinned Workspaces (Hot Files)
-To maintain focus on the active "working set" of files in large repositories, use pins.
-- **pin_file / unpin_file:** Pin the 3-5 files you are actively modifying to the current 
-amespace (project).
-- **list_pinned_files:** When starting a new session or returning to a project, always list pinned files first to instantly regain context on what was being worked on.
+> [!IMPORTANT]
+> * **Tier 1 (Static Markdown)**: Repository rules, constraints, architectural patterns, and developer preferences are maintained directly in static git-tracked files (`agent-rules/*.md`, `instructions.md`) and system prompts. This guarantees 0ms turn-0 availability without relying on proactive agent tool retrieval.
+> * **Tier 2 (Telemetry & Ephemeral DB)**: High-frequency operational history—the Code Change Ledger (`audit_ledger`), terminal command history, compiler error fixes (`log_error_fix`), active tasks, and preflight context—is handled by the MCP Memory Server and surfaced via the Brain Monitor Web UI and MCP resources.
 
-## Rolling Session Summaries (Project Timeline)
-To maintain a chronological narrative of the project's evolution beyond just code diffs.
-- **add_session_summary:** At the end of every major coding session, write a 2-sentence summary of what was accomplished and add it to the 
-amespace.
-- **get_project_timeline:** When rejoining a project after a long time, read the timeline to instantly understand the recent architectural history.
+---
 
-## Agent Handoffs (The Inbox)
-When working in a multi-session or multi-agent environment, agents need to communicate context across time.
-- **leave_handoff_memo:** Leave a quick message describing current progress, roadblocks, or the literal next step to take.
-- **read_handoff_memos:** ALWAYS check for memos when waking up in a new project namespace.
-- **clear_handoff_memos:** Clear the memo after you have successfully read it and absorbed its context.
+## 3. Passive MCP Resources (`resources/list`)
 
-## Environment & Blueprint Tracker
-Stop wasting tokens rediscovering how to run or configure the project.
-- **update_env_fingerprint:** Run this when you set up a new project to snapshot the OS, shell, and key language versions (e.g. python, 
-ustc).
-- **read_env_fingerprint:** Query this to instantly know how the project is run.
-- **log_env_requirement:** Log required .env variables (e.g. DATABASE_URL) without logging the secret itself.
+The server exposes 9 real-time, read-only MCP resources. Agents should read these resources directly to regain context without incurring tool call latency:
 
-## Milestones (Epics)
-Organize granular tasks into high-level phases.
-- **add_milestone:** Group a large subset of work into a cohesive phase (e.g., "V1 MVP", "CI/CD Setup").
-- **update_milestone:** Mark a milestone as active, blocked, or completed.
-- **list_milestones:** Use this to ensure task priorities align with the current active milestone.
+| Resource URI | Resource Name | Description & Usage |
+|:---|:---|:---|
+| `memory://graph/entities` | Graph Entities | All nodes and entities in the knowledge graph (top 100 with pagination guidance). |
+| `memory://graph/relations` | Graph Relations | All relationships between graph entities (top 200 with subgraph guidance). |
+| `memory://tasks/active` | Active Tasks | Current active tasks with status, priority, and assigned subagents. |
+| `memory://decisions/active` | Active ADR Decisions | Architectural decisions currently in `accepted` status. |
+| `memory://tech_debt/unresolved` | Unresolved Tech Debt | All open engineering debt items requiring future refactoring. |
+| `memory://session/delta` | Session Delta | Code modifications, commits, active tasks, and notes created in the last 2 hours. |
+| `memory://terminal/recent` | Terminal History | Recent terminal commands, interpreters (`pwsh`, `bash`, `nu`), working dirs, and exit codes. |
+| `memory://activity/recent` | Recent Activity | Real-time IDE and developer activity event stream. |
+| `memory://milestones` | Milestones | Project milestones, deliverables, target dates, and progress. |
 
-## Standup Reports
-When asked for a progress update or standup report, do not guess or read raw git logs.
-- **generate_standup_report:** Generates a structured JSON containing all 	asks updated, code_changes logged, and session_summaries added within the last N hours. Format this cleanly as a markdown report for the user.
+---
 
-## Infrastructure & Environment Registry
-Avoid asking the user for URLs or connection details repeatedly.
-- **register_environment:** Save connection details for Dev, QA, Staging, or Prod environments.
-- **get_environment_details:** Query this to know how to connect to databases, APIs, or VPNs.
+## 4. MCP Workflow Prompts (`prompts/list`)
 
-## Pre-Push / PR Quality Checklists
-Ensure high code quality and prevent incomplete pull requests.
-- **add_pr_checklist_item:** Add recurring repository chores (e.g., "Run cargo fmt", "Update CHANGELOG").
-- **get_pr_checklist:** Query and explicitly verify EVERY item on this list before triggering git push or merging PRs.
-- **clear_pr_checklist:** Clear if the project lifecycle changes dramatically.
+The server registers 5 high-signal workflow prompts to initiate standardized agent routines:
 
-## Tech Debt & Refactor Backlog
-Keep the main task board clean by isolating "hacky" workarounds.
-- **log_tech_debt:** Record why a shortcut was taken and what the ideal solution should be.
-- **resolve_tech_debt:** Mark a debt as paid off once refactored.
-- **list_tech_debt:** Query this before starting a refactoring session.
+1. **`context_warmup`**: Executed at session startup. Prompts the agent to read `memory://tasks/active` and `memory://session/delta`, inspect the workspace worktree, and assemble immediate working context.
+2. **`analyze_tech_debt`**: Prompts the agent to review unresolved technical debt from `memory://tech_debt/unresolved` and generate a prioritized remediation plan.
+3. **`summarize_architecture`**: Synthesizes active ADRs from `memory://decisions/active` and graph entities from `memory://graph/entities` into an architectural overview.
+4. **`handoff_routine`**: Triggers the `DevOpsSRE` subagent at session end to generate a standup report, audit active tasks, and record a handoff memo for future sessions.
+5. **`archive_routine`**: Compresses historical session summaries into a dense milestone retrospective entity and purges pruned entries.
 
-## Context Workspaces
-When shifting context rapidly (e.g. from building a feature to fixing a prod bug), save your state.
-- **save_context_workspace:** Save your active pinned files and task IDs under a named workspace (e.g., "Feature X").
-- **load_context_workspace:** Retrieve a saved workspace to instantly restore your context when returning to that task.
-- **list_context_workspaces:** List all saved workspaces in a project.
+---
 
-## Omni-Search (Global Vault Search)
-When you remember a vague keyword but don't know which specific vault it's stored in.
-- **omni_search:** Searches across the Knowledge Graph, Tasks, Snippets, ADRs, Tech Debt, Memos, and Error Fixes simultaneously.
+## 5. Consolidated Smart Tools Architecture (11 Primary Tools)
 
-## Project Health Dashboard
-When starting a new session, get a numerical aggregate of the project's current state.
-- **get_project_health:** Returns a quick digest of active tasks, unread memos, unresolved tech debt, and pending PR checklist items.
+The server consolidates granular single-purpose tools into domain-named smart tools.
 
-## Git Context Binding (VCS Sync)
-To maintain absolute traceability, we link memory items directly to the exact git commits they occurred on.
-- **Fully Automated (git2):** You no longer need to manually execute `git rev-parse HEAD` or pass `git_branch` / `git_commit` arguments. 
-- When you call tools like **log_code_change**, **log_error_fix**, or **log_tech_debt**, the Rust server uses the native `git2` crate to automatically discover the repository context of the active working directory, extract the current HEAD commit hash, message, and branch, and permanently bind them to the memory item in the background.
+* **`tasks`**: Complete task lifecycle management.
+  - `action: "add"`: Create a new task (requires `title`, optional `description`, `git_branch`, `repo_name`, `priority: "low" | "medium" | "high" | "urgent"`, `assigned_agent`, `verification_command`, `parent_id`, `dependencies`).
+  - `action: "update"`: Update task status (requires `id`, `status: "pending" | "completed" | "cancelled"`).
+  - `action: "delete"`: Delete task and child tasks (requires `id`).
+  - `action: "list"`: List active tasks (optional `git_branch`, `summary_level: "compact" | "detailed" | "full"`, `max_tokens`).
+  - `action: "set_criteria"`: Set acceptance criteria (requires `id`, `criteria: Vec<String>`).

+  - `action: "list"`: List milestones (optional `namespace`).
 
-## 15. Neovim Integration & God Mode
-The project contains two MCP binaries (win-nvim and linux-nvim) that bridge JSON-RPC over stdio directly to the active Neovim instance (using ctive_nvim.txt for Last Focused Wins telemetry). 
-- These binaries expose basic tools (
-vim_get_cursor, 
-vim_get_active_buffer, 
-vim_list_buffers, etc.).
-- **God Mode**: They also expose 
-vim_execute_lua. This is the ultimate fallback tool. If you need to access *any* Neovim API that does not have a dedicated Rust tool (e.g., getting LSP diagnostics, evaluating a visual selection block based on modes, setting registers), you MUST write a short Lua script and pass it to 
-vim_execute_lua. Do not attempt to recompile the Rust server to add new basic tools; use the Lua escape hatch dynamically.
+* **`handoff_memos`**: Session handoff notes for future agents.
+  - `action: "leave"`: Leave a memo (requires `content`, optional `vcs_revision`, `repo_name`, `git_branch`, `blockers: Vec<String>`, `action_items: Vec<String>`, `expires_at`).

+
+---
+
+## 9. Automated Error Fix Auto-Matcher
+- **Tools:** `log_error_fix`, `search_error_fixes` (and alias `suggest_error_fix`)
+- **When to use:** When encountering a build error, test failure, or stack trace. Call `search_error_fixes` with either a text `query` or `stack_trace` before attempting a fix from scratch.
+- **Behavior:** Computes cosine similarity between error trace embeddings and past resolution logs when `stack_trace` is provided, or keyword filtering when `query` is provided, returning top matched solutions, modified files, and git commits.
+
+---
+
+## 10. Memory State Checkpointing & Rollbacks
+- **Tool:** `manage_checkpoint` (action: `"create"` | `"restore"`)
+- **When to use:** Before initiating a large refactor, running experimental subagent tasks, or executing destructive batch operations.
+- **Behavior:** Saves or restores a point-in-time snapshot of graph entities, active tasks, and tech debt backlogs.
+
+---
+
+## 11. Self-Healing Graph Health Sweeper
+- **Tool:** `sweep_graph_health`
+- **When to use:** Periodically or before committing major graph changes to audit entity consistency.
+- **Behavior:** Detects orphaned nodes (0 relations), computes name similarity using pre-computed lowercase keys to identify near-duplicates (e.g., `APIGateway` vs `ApiGateway`), and provides structured `merge_entities` recommendations or auto-prunes orphans.
+
+---
+
+## 12. Causal Lineage & Provenance Tracker
+- **Tool:** `query_lineage`
+- **When to use:** When asking *"Why was this component modified?"* or *"What task or ADR led to this code change?"*
+- **Behavior:** Searches across tasks, ADRs, audit ledger entries, and error fixes to assemble a unified chronological timeline explaining the provenance behind any file, symbol, or commit.
+
+---
+
+## 13. ADR Lifecycle & Automated Git Post-Commit Reconciliation
+
+- **The Golden ADR Rule**: When code implementing an ADR is committed, you MUST IMMEDIATELY update the ADR status to `implemented`:
+  ```json
+  {
+    "action": "update",
+    "id": "ADR-XXXX",
+    "status": "implemented",
+    "git_commit": "<commit_hash>",
+    "git_branch": "<branch>"
+  }
+  ```
+- **Automated Post-Commit Hook**: The repository provides an automated reconciliation script (`scripts/git-reconcile.py`) installed via `just install-git-hooks`. Upon every `git commit`, the hook scans the commit message for `ADR-XXXX` or task identifiers and reconciles their status in the persistent store.
+- **Current Architecture Status**: 100% of defined ADRs (ADR-0080 through ADR-0104) are fully implemented and reconciled in the store.
+

+
+## 14. Native Rust Invariants & Subprocess Prohibition (CRITICAL)
+
+To maintain maximum security, speed, and cross-platform reliability:
+* **Zero Subprocess Fallbacks**: System and server tools (`clipboard`, `ast`, `search`, `db`) MUST strictly use pure native Rust crates (`arboard`, `tree-sitter`, `tantivy`, `psycopg`). Invocations of external shell commands (`powershell.exe`, `wl-paste`, `xclip`, `cmd.exe`) are strictly prohibited in native handlers.
+* **Transient Lock Recovery**: Transient OS handle collisions (such as Win32 OLE `OpenClipboard` lock contention) must be handled using native retry loops with backoffs directly in Rust.
+* **Automated Static Regression Gates**: Automated AST/source audit tests (`test_no_subprocess_clipboard_regression`) verify at test time that forbidden subprocess patterns are absent from handler implementations.
+
+---
+
+## 15. High-Performance Concurrency & Resilience Guarantees
+
+* **Explicit Fail-Fast Persistence Safety**: Replaced silent fallback to temporary databases (`/tmp/mcp_store_fallback_*`) with an explicit open retry and fail-fast panic unless `MCP_ALLOW_TMP_FALLBACK=1` is explicitly set, preventing silent data loss.
+* **Async Mutex Deadlock Elimination**: Converted shared state and Neovim connection locks (`shutdown_tx`, `NVIM_CONN`, `ACTIVE_SOCKET`, `HEADLESS_PROC`) to `tokio::sync::Mutex` to prevent worker thread pool starvation across `.await` points.
+* **Telemetry Session Deduplication & Channel Pruning**: Added `LAST_SESSION` in-memory state deduplication for UDP telemetry writes (eliminating disk I/O thrashing) and distinguished WebSocket `TrySendError::Full` backpressure vs `TrySendError::Closed` client pruning.
+* **Graph Adjacency Indexing**: Leverages `KnowledgeGraph::build_adjacency_map` to build $O(1)$ lookup adjacency lists for fast BFS shortest path graph queries.
+* **Atomic Store Write Lock Minimization**: `Store::modify` and `Store::modify_async` release write guards immediately after in-memory state mutations, serializing JSON payloads under read locks to allow non-blocking concurrent readers.
+* **Async Commit Index Reader Auto-Reload**: `MemoryIndex::commit()` automatically triggers `reader.reload()` upon completing background commits, guaranteeing immediate visibility of newly indexed document terms.
+* **Zero-Allocation NDJSON Reader**: `mcp-stdio` reclaims line buffers via `std::mem::take` and in-place trimming to eliminate heap allocations during high-frequency NDJSON message parsing.
+* **Dynamic Character Micro-Batched Fastembed Inference**: `generate_embeddings_async` dynamically batches text arrays using a 16,000 character budget ceiling inside `spawn_blocking`, preventing heap spikes during vector indexing while keeping ONNX SIMD execution saturated.
+* **Bounded Telemetry Detail Records**: Activity and terminal telemetry buffers enforce a 4,000 character truncation ceiling on log details (`ActivityRecord`, `TerminalHistory`) to prevent unbounded RAM growth under high RPC throughput.
+* **Zero-Allocation Stream Formatting**: Graph condensation loops (`condense_graph_worker`) format node/relation subgraphs into stream buffers via `std::fmt::Write`, eliminating intermediate String allocation overhead.
+* **Single-Handle OS Clipboard Retries & Image Downsampling**: `WriteClipboardHandler` initializes OS clipboard handles once per operation and downsamples images exceeding $2048 \times 2048$ resolution before writing raw RGBA bytes.
+* **Zero Transaction Drop Persistence Guarantee**: `Store::modify` automatically spawns an async task to execute `push_async` with channel backpressure if `push` encounters queue saturation, ensuring zero data loss under spike write loads.
+* **Token-Budgeted Query Projections**: Decision queries (`query_decisions`) support `limit` caps and compact `include_body: false` projections for token budget optimization.
+* **Serde Parameter & Enum Ergonomics**: Action enums (`SnippetSearchMode`, `Relation`) support case-insensitive variants and common synonyms (`create`/`add`, `remove`/`delete`, `list`/`read`, `source`/`from`, `target`/`to`, `relationType`/`relation_type`) ensuring seamless LLM tool execution.
+* **Atomic Search Index Swaps**: `MemoryState::rebuild_index` constructs and populates a new `MemoryIndex` instance in isolation before performing an atomic pointer swap (`*self.search_index.write().await = new_idx`), eliminating transient empty search result windows.
+* **Non-Blocking Tantivy Search Queries**: `MemoryIndex::search` queries current index searcher snapshots without executing synchronous disk commit locks, preventing query stalls during heavy background indexing.
+* **Zero-Allocation HashSet<&str> Snippet Deduplication**: `indexer.rs` utilizes borrowed `HashSet<&str>` name lookups during snippet batch modifications, eliminating heap string re-allocations inside the store write lock.
+* **AST Recursion Depth Safeguard & Zero-Copy Borrowing**: Tree-sitter AST traversal caps recursion depth at 100 to prevent thread stack overflows and borrows string slices (`&str`) during AST node walking.
+* **Strongly-Typed SearchResult & Pre-Allocated Search Vectors**: `search.rs` uses a strongly-typed `SearchResult` struct with named fields and pre-allocates result vector capacity (`Vec::with_capacity(top_docs.len())`).
+* **BFS Graph Traversal Pre-allocation & Visited Node Upper Bound**: `GraphQueryBuilder::find_shortest_path` pre-allocates adjacency map capacity (`HashMap::with_capacity(relations.len() * 2)`) and enforces a visited node upper bound (10,000 max) to guarantee deterministic BFS runtime.
+* **Filesystem Event Debouncing & Proactive State Refresh**: `spawn_watcher` implements a sliding 250ms debouncing window per file path, ignores `.git`, `target`, `.gemini`, and `node_modules`, and broadcasts activity events to `MemoryState`.
+* **Buffered Line-by-Line AST Workspace Symbol Scanning**: `scan_workspace_for_symbol` reads workspace files via `BufReader` line streams instead of loading entire files into heap strings, preventing memory spikes when traversing source trees.
+* **AST Node Type Aliasing & Skeleton Preallocation**: `replace_ast_node` documents friendly node aliases (`function`, `fn`, `method`, `struct`, `class`, `enum`, `trait`, `type`), and `read_file_skeleton` preallocates string buffer capacity (`code.len() / 2`).
+* **Batch Vector Indexing & Similarity Score Guidance**: `VectorDB` provides `index_documents_batch` for single-request multi-point vector upserts and explicit score calibration notes ($\ge 0.75$ high confidence match).
+* **Compact JSON MCP Resources & UTF-8 Activity Truncation**: MCP resources serialize using compact JSON (`to_string`), `TerminalHistoryResource` / `MilestonesResource` enforce output bounds, and `format_tool_activity_description` uses `floor_char_boundary` for guaranteed UTF-8 safety.
+* **SIMD-Friendly Single-Pass Cosine Similarity**: `cosine_similarity` calculates dot product and Euclidean norm squares in a single linear pass over float vectors, enabling SIMD compiler auto-vectorization.
+* **Safe Stream Decoding on Log Tails**: Log tail operations (`process_logs`, action: "get") read raw bytes and decode using lossy UTF-8 conversion (`String::from_utf8_lossy`) to ensure resilience when seeking across multi-byte UTF-8 boundaries.
+* **Task Summary UTF-8 Truncation Safety**: `tasks` tool (`action = "list"`) truncates serialized task text strictly along UTF-8 character boundaries using `floor_char_boundary` when enforcing `max_tokens`.
+* **Directory Tree Depth Safeguard**: `ReadDirectoryArchitectureHandler` caps directory recursion at depth 10 to prevent stack overflow on deep or cyclic directory structures.
+* **Deterministic Total-Order Score Ranking**: `OmniSearchHandler` uses `f64::total_cmp` for Reciprocal Rank Fusion (RRF) score sorting, guaranteeing deterministic NaN-safe search result ordering.
+* **RPC Timeout Memory Hygiene**: `nvim-core` maintains request hygiene by removing pending request entries from static RPC maps upon timeout or channel drop, eliminating orphan memory leaks.
+* **Path Traversal Security Guards**: `validate_safe_path` enforces path canonicalization and rejects relative parent traversal components (`..`) across file and process log handlers (`process_logs` / `ProcessLogsTool`).
+* **Watcher Map Memory Eviction**: Proactive daemon file watcher in `watcher.rs` caps `last_processed` map size at 1,000 entries and purges entries older than 10 minutes to prevent monotonic memory leakage.
+* **Comprehensive Serde Casing Aliases**: All 11 consolidated tool action enums (TaskAction, MilestoneAction, SnippetAction, DecisionAction, TechDebtAction, EnvAction, ClipboardAction, HandoffMemoAction, HypothesisAction, AgentSignalAction, ProcessLogAction) include serde alias attributes supporting `snake_case`, `camelCase`, `PascalCase`, and uppercase variants for maximum LLM casing resilience.
+* **Two-Phase Graph Condensation**: `condense_graph_worker` uses a 2-phase commit (non-destructive `read_with` -> graph insert -> prune by timestamp/content) to prevent data loss if summarization or graph insertion fails.
+* **Redb Database Lock Retry Backoff**: `init_db` retries transient Redb lock contention with exponential backoff (3 attempts, 150ms delay) before falling back.
+* **Offloaded Background Index Rebuilds**: `MemoryState::rebuild_index` offloads graph snapshot cloning and Tantivy document re-indexing into `tokio::task::spawn_blocking` to avoid stalling async event loops.
+* **Broadcast Watch-Based Shutdown Channels**: Background workers utilize `tokio::sync::watch` for broadcast shutdown notifications without consuming cancellation signals.

+# Antigravity Neovim MCP Instructions
+
+When connected to this Neovim MCP server (`win-nvim`), you have powerful tools to interact directly with the active Neovim editor.
+
+## The Consolidated Tool Arsenal (v3)
+The server consolidates granular Neovim operations into 5 smart mega-tools:
+- **`nvim_buffer`**: Buffer and file management. Actions: `read`, `replace`, `save`, `undo`, `redo`, `create_scratch`.
+- **`nvim_workspace`**: Window split and focus management. Actions: `list_buffers`, `list_windows`, `focus`, `split`, `cwd`.
+- **`nvim_intelligence`**: Code intelligence and LSP. Actions: `hover`, `definition`, `references`, `outline`, `query`, `diagnostics`, `rename`, `code_action`.
+- **`nvim_ui`**: Visual highlighting, diff previews, and ghost text. Actions: `highlight`, `ghost_text`, `clear`.
+- **`nvim_exec`**: Escape hatch for raw evaluation. Actions: `lua`, `vimscript`, `terminal`.
+
+## 1. Using Consolidated Domain Tools First
+Always prefer the specific consolidated tools (like `nvim_buffer`, `nvim_workspace`, `nvim_ui`, etc.) over writing raw Lua scripts. These tools are strongly typed, tested, and safe.
+
+## 2. Lua God Mode (`nvim_exec` with action `lua`)
+If you need to access *any* Neovim API that does not have a dedicated tool (e.g., changing options, setting autocmds), you MUST use `nvim_exec` with action `lua` as your escape hatch.
+**CRITICAL**: `nvim_exec` is restricted to **READ-ONLY** queries. Do NOT use it to mutate editor state.
+
+### CRITICAL RULES for `nvim_exec` (`lua`):
+1. **Never Block:** Never use interactive prompt functions or interactive confirmation flags in substitutions (e.g., `%s/old/new/gc`). This will cause the headless MCP bridge to deadlock forever.
+2. **Visual Feedback:** Always trigger a notification using `require("notify")("Antigravity: [Action]", "info", { title = "Antigravity" })`.
+3. **Auto-Save:** If you modify a file buffer, always save it using `vim.cmd('write')` within the same Lua script so external tools can see the changes, unless you explicitly want to pause for manual human review.
+4. **Buffer Focus & Centering:** When making changes to a buffer, switch the active window to that buffer, jump to the edited line/column (`vim.api.nvim_win_set_cursor(0, {line, col})`), and center the viewport horizontally and vertically (`vim.cmd('normal! zz'); vim.cmd('normal! ' .. col .. '|zs')`) so the user immediately sees the change in full context.
+
+## 3. The "Unix is NOT King" Rule
+You should **ALWAYS prioritize Neovim tools over basic unix terminal utilities** (like `cat`, `grep`, `sed`, `awk`, or PowerShell equivalents) for file read/writes and search/replace. If an interactive Neovim session is not currently open, the server will automatically connect or spawn a persistent headless Neovim daemon in the background to execute your commands. 
+
+**CRITICAL PAIR-PROGRAMMING EXCEPTION:** 
+While the headless background instance is great for autonomous, routine tasks, if you are performing collaborative "pair programming" activities, complex refactors that require visual engagement, or step-by-step human review, **DO NOT** execute them blindly in the background. Instead, explicitly ask the user to open a Neovim UI first so they can visually follow along. Use Neovim as your primary AST-aware interface to the codebase at all times.
+
+## 4. Tool Schema Discovery
+Do **NOT** grep or search the Rust source code to find tool schemas or arguments. All lazy-loaded MCP tool schemas are automatically cached as JSON files on your disk. To understand a tool's arguments, directly read `~/.gemini/antigravity-cli/mcp/win-nvim/<tool_name>.json` (or linux-nvim).
