   - `agents/fitness/`, `agents/itguy/`, `agents/hebamme/`, `agents/recherche/`: >100 MB each + multi-megabyte WAL files.
   On startup, SQLite WAL recovery and integrity passes across 10+ databases on single-node hostpath storage can take several minutes. If this exceeds the `startupProbe` limit (`failureThreshold * periodSeconds`), Kubernetes kills the container before it finishes opening databases.
 - **Resolution**:
-  1. Ensure `probes.startup.failureThreshold` in `openclaw-instance.secret.yaml` allows adequate startup headroom (e.g. at least 120 attempts with 5s period = 600s).
+  1. Increase `probes.startup.failureThreshold` in `openclaw-instance.secret.yaml` to 240 (with 5s period = 1200s / 20 min).
-  2. Periodically ensure SQLite VACUUM / WAL checkpoints run during maintenance windows or let the database open without interrupting it.
+  2. Periodically run `PRAGMA wal_checkpoint(TRUNCATE)` across all SQLite databases to compact WAL journals into main files.
 - **How to Avoid Recurrence**:
   Monitor SQLite database sizes under `/home/openclaw/.openclaw/agents/*/agent/` and avoid overly aggressive liveness/startup probe kill thresholds during gateway initialization.

+### Issue 4: Bootstrap File Rejection due to Inode Hardlink Security Boundary
+
+- **Date**: 2026-09-28
+- **Severity**: High (Subagents lose access to user profile and memory context)
+- **Symptom**:
+  On every message turn directed to subagents (e.g. Hebamme, Koch, IT Guy), the gateway log reports:
+  ```text
+  [workspace] bootstrap file is unreadable: file=/home/openclaw/.openclaw/workspace-<subagent>/USER.md reason=path must not be hardlinked
+  [workspace] bootstrap file is unreadable: file=/home/openclaw/.openclaw/workspace-<subagent>/MEMORY.md reason=path must not be hardlinked
+  ```
+- **Root Cause**:
+  OpenClaw’s embedded execution harness enforces a strict filesystem security check: `stat.nlink > 1` triggers `path must not be hardlinked`. This prevents cross-agent symlink/hardlink inode attacks or unauthorized file modification. An earlier optimization created hardlinks between the main workspace and subagent workspaces, causing all subagents to reject the bootstrap files.
+- **Resolution**:
+  Decouple all hardlinked files so that each workspace has its own standalone copy with `nlink == 1`:
+  ```bash
+  for dir in /home/node/.openclaw/workspace-*; do
+    for file in USER.md MEMORY.md; do
+      cp --remove-destination "/home/node/.openclaw/workspace/$file" "$dir/$file"
+    done
+  done
+  ```
+  Ensure the init container in `openclaw-instance.secret.yaml` maintains this pattern with `cp --remove-destination`.
+- **How to Avoid Recurrence**:
+  Never create hardlinks (`ln` without `-s`) inside OpenClaw workspace directories. Always use standalone file copies (`cp --remove-destination`).

+
+### Issue 5: Cron Trigger Sandbox Scope ReferenceError
+
+- **Date**: 2026-09-28
+- **Severity**: Medium (Automated recurring cron job fails to evaluate)
+- **Symptom**:
+  In `cron_run_receipts`, the job `rennerhof-website-watch` failed with:
+  ```text
+  cron trigger evaluation failed (internal_error): ReferenceError: state is not defined
+      at <anonymous> (openclaw-code-mode:user.js:12:172)
+  ```
+- **Root Cause**:
+  The JavaScript execution sandbox for OpenClaw custom triggers does not initialize global variables if no state was previously stored. The script attempted to access `state && state.hash` directly, causing a `ReferenceError` when `state` is undeclared in the global scope.
+- **Resolution**:
+  Use `typeof state !== "undefined"` to safely guard against undeclared variables in the trigger script:
+  ```javascript
+  const s = (typeof state !== 'undefined' && state) ? state : {};
+  const prev = s.hash;
+  ```
+- **How to Avoid Recurrence**:
+  In OpenClaw trigger scripts, never evaluate bare identifier `state` directly without a `typeof` guard.
