fix(zulip): remove invalid kwargs from SendResult calls

SendResult only accepts: success, message_id, error, raw_response,
retryable. The adapter was passing platform=, chat_id=, and metadata=
which are not valid fields, causing TypeError on every send attempt.

This was the error Tanko was showing in Zulip:
'SendResult.__init__() got an unexpected keyword argument "platform"'

+# PR #21 Review — fix(tanko): adapter fixes, event logging, platform-based deploy.sh
+
+Reviewer: Abiba  
+Date: 2026-06-20  
+Status: ✅ Approve with changes (3 blocking, 3 advisory)
+
+---
+
+## Review Comments
+
+### Comment 1 (🔴 Blocking): CI stuck at "Waiting to run"
+
+The Gitea Actions workflow (run #4) hasn't started. No CI results available. Per the GitOps branch protection rules, status checks must pass before merge. Do not merge until CI completes and all jobs are green.
+
+---
+
+### Comment 2 (🟡 High): `print()` for journald is an anti-pattern
+
+In `adapter.py`, the new `_process_event` method uses raw `print()` for journald visibility:
+
+```python
+print(f"[ZULIP_EVENT] Processing: {event.get('type', 'unknown')}")
+```
+
+The existing `logger.info()` calls already flow to journald via stderr when the systemd unit uses `StandardError=journal`. Using raw `print()` bypasses:
+- Log level filtering
+- Format consistency with other log output
+- Future structured logging needs
+
+**Fix:** Replace with `logger.info(f"[ZULIP_EVENT] Processing: {event.get('type', 'unknown')}")`.
+
+---
+
+### Comment 3 (🟡 High): `asyncio.new_event_loop()` leaks on thread restart
+
+In `_event_loop`, a new event loop is created but never closed:
+
+```python
+def _event_loop(self) -> None:
+    loop = asyncio.new_event_loop()
+    asyncio.set_event_loop(loop)
+    try:
+        self._client.call_on_each_message(...)
+    except Exception as e:
+        logger.error(f"Event loop crashed: {e}")
+        self.connected = False
+```
+
+If the thread restarts (e.g., reconnection), the old loop is leaked. This accumulates over time.
+
+**Fix:** Wrap in `try/finally`:
+
+```python
+def _event_loop(self) -> None:
+    loop = asyncio.new_event_loop()
+    asyncio.set_event_loop(loop)
+    try:
+        self._client.call_on_each_message(
+            lambda event: self._process_event(event),
+        )
+    except Exception as e:
+        logger.error(f"Event loop crashed: {e}")
+        self.connected = False
+    finally:
+        loop.close()
+```
+
+---
+
+### Comment 4 (🟡 Medium): Verify `Client(site=...)` parameter name
+
+The PR changes `Client(server_url=...)` → `Client(site=...)` for "Python 3.13 compatibility." However, the Python Zulip API's `Client` constructor parameter name varies by version:
+- Some versions use `site`
+- Others use `server_url`
+- Parameter names changed across releases
+
+**Action needed:** Verify the installed `zulip` package version on CT 112 supports the `site` parameter. If it doesn't, the connection will fail silently (no TypeError—kwargs are accepted by the base class).
+
+---
+
+### Comment 5 (🟡 Medium): deploy.sh refactor only tested on Hermes platform
+
+The PR refactors `deploy.sh` across all 3 platforms (Hermes, Agent Zero, Pi) but testing only covers Tanko (Hermes) on CT 112. The Agent Zero (`pip install -r requirements.txt`) and Pi (`/reload` instead of `systemctl`) code paths are untested.
+
+**Action needed:** Before merging, run at minimum a dry-run deploy against all 3 platform types:
+```
+./scripts/deploy.sh --ct=kagentz main --dry-run
+./scripts/deploy.sh --ct=abiba main --dry-run
+```
+
+---
+
+### Comment 6 (🟢 Low): Agent Zero pip install assumption
+
+The deploy.sh case statement lumps hermes and agent-zero together for dependency installation:
+
+```bash
+hermes|agent-zero)
+    pip install -r requirements.txt --quiet
+    ;;
+```
+
+This assumes Agent Zero has the same `requirements.txt` location and content as Hermes. If Agent Zero uses a different dependency file or install method, this will silently install wrong packages.
+
+**Suggestion:** Add a per-platform dependency install path or document this assumption explicitly.

+# Zulip Multi-Platform Agent Communication — Architecture (v2)
 
 ## Overview
 A production-ready system enabling 6 AI agents across 3 platforms (Hermes Python, Agent Zero, pi TypeScript) to communicate through Zulip via dedicated per-agent bot users.
 
+## Architecture (Hermes Native Plugin — Current)
+
+As of v1.0.0, Hermes agents (Tanko, Mumuni, Koonimo, Koby) use the **Hermes native platform plugin**
+at `~/.hermes/plugins/platforms/zulip/`. This replaces the old standalone systemd service.
+
+Benefits of the native plugin:
+- Extends `BasePlatformAdapter` — zero changes to Hermes core
+- Auto-registers via `register(ctx)` at Gateway startup
+- Direct session injection (no subprocess overhead)
+- Leverages Gateway's built-in health checks, config, and error handling
+- Unified logging with all other Hermes platform adapters
