+### Issue 25: Self-Quoting Duplicate Meal Logging & Turn Bleed on High-Context Session (Topic 21)
+
+- **Date**: 2026-10-12
+- **Severity**: Medium (Morning porridge was logged twice on 2026-10-12, inflating daily intake to 1,906 kcal instead of 1,611 kcal; redundant pudding correction was appended to 2026-10-11)
+- **Symptom**:
+  Moritz noticed on the personal health dashboard (`moritz.html`) that his morning porridge had been recorded twice.
+- **Root Cause Isolated via Rapid Triage**:
+  1. **Extreme Context Bloat**: Session `aff9fd77` in Topic 21 had accumulated **58,856 tokens** across 103 events due to heavy tool results and previous turns.
+  2. **External Tool Attention Disorientation**:
+     - At 08:41 (SEQ 32–37), the morning porridge was properly logged in 4 individual items (`01M4QDGVY...` to `01M4QDH51...`, ~295 kcal total).
+     - At 11:35 (SEQ 39), Moritz sent an audio message reporting 1.5 Brezen mit Butter, Weißwürste, and Händlmaier sweet mustard.
+     - The assistant performed an external Perplexity web search for mustard calories, which returned ~16 kB of text.
+     - Upon receiving the search result at SEQ 49, `z-ai/glm-5.3-flash` suffered severe attention disorientation: seeing `replyToId: 21` (standard Telegram forum topic metadata) and earlier messages in context, it hallucinated that earlier completed turns were unhandled requests.
+  3. **Self-Quoting Duplicate Execution**:
+     - In SEQ 51, the model literally copied its own earlier assistant confirmation text from SEQ 37 (`✅ *Morgenporridge (60 g Mischung · 60 ml Hafermilch · 120 ml Wasser · 50 g Kiwi)* geloggt`) and executed `datastore.py add` to log a duplicate 295 kcal composite portion (`01M4QQH2KJ85TB5N2MBM230ZYN`).
+     - In SEQ 53, it did the same for yesterday's pudding correction (`01M4QQHMG8S30B43241B10ND3J`, +260 kcal).
+- **Resolution**:
+  1. **Deleted Duplicate Events via Datastore CLI**:
+     - Deleted duplicate porridge event `01M4QQH2KJ85TB5N2MBM230ZYN` (295 kcal) and duplicate pudding event `01M4QQHMG8S30B43241B10ND3J` (260 kcal) via `datastore.py delete`.
+     - Re-rendered all views and published updated dashboards (`render_views.py` & `update_moritz_website.py`). Today's total restored to exact **1.611 kcal** (**75,1 g Protein**).
+  2. **Notified Telegram Topic 21**:
+     - Sent confirmation message (Message ID `2700`) to Topic 21 detailing the correction and showing the cleaned-up macros.
+  3. **Hardened `knowledge-wiki/agents/koch.md`**:
+     - Added strict rule: *„KEINE DUPLIKATE ODER SELBST-ZITATE LOGGEN“*. Explicitly forbidden from parsing previous assistant confirmation messages as intake items and forbidden from re-logging earlier completed meals.
+  4. **Session Reset**:
+     - Safely deleted and archived the bloated 58k-token session via `openclaw sessions delete`.
+  5. **Triage Script Optimization**:
+     - Updated `openclaw-triage.py` to automatically exclude background `:heartbeat` sessions when querying by topic ID.
+- **How to Avoid Recurrence**:
+  - System prompts for transactional logging agents must explicitly forbid treating assistant confirmation messages as intake events.
+  - Agents must enforce strict focus on the very last user message at the tail of the transcript.
+  - Reset sessions periodically when context grows beyond 30k tokens for simple transactional logging tasks.
