+## 8. Webhook Telemetry & Passive Ingestion
+The server features a suite of webhook listeners that passively ingest development activity to build context without requiring human copy-pasting:
+*   **Terminal Ingestion (`/terminal/telemetry`):** Shell hooks (PowerShell/Nushell) silently POST command execution history and exit codes, allowing agents to read recent stack traces via the `memory://terminal/recent` resource.
+*   **IDE Telemetry (`/nvim/telemetry`):** A connectionless UDP datagram listener receives focus events from Neovim, broadcasting the user's active file to the UI and Agent instantly.

+## 9. 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.

 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.
 
 ## 18. Upcoming Enhancements
-### A. Vector Embeddings for Semantic Search
-The `omni_search` will be upgraded from purely lexical `tantivy` indexing to include a local ONNX embedding model (via `fastembed`). This allows semantic retrieval of `ErrorFix` and `TechDebt` entries even when exact vocabulary does not match.
 
-### B. Passive Terminal Ingestion
-A shell hook system (PowerShell/Nushell) will silently POST terminal execution history and exit codes to `/terminal/history`. LLMs can passively read this via the `memory://terminal/recent` resource, eliminating the need for the user to manually copy/paste stack traces.

-### C. Graph Summarization & Decay
+### A. Graph Summarization & Decay
 To prevent context window bloat, the Redb engine will enforce TTLs on ephemeral nodes (`StickyNotes`, minor `Tasks`). Furthermore, an `archive_routine` prompt will allow subagents to automatically compress older `SessionSummaries` into dense milestone retrospectives.
 
+### B. Proactive Subagent Triggers
+The daemon will eventually gain the ability to autonomously spawn background subagents (like the `BugDiagnostician`) when specific events are detected in the webhook telemetry, rather than relying strictly on the human user to initiate the agent.
