### Summary
Multi-type memory prompts were assembled from sets, so their instruction
and output sections could change order across Python processes with
different hash seeds. Because the generated default prompt is persisted
and later compared as a string, a restart could make an untouched
default look custom and prevent it from being regenerated when memory
types change.
## Summary
- require a `valid_at` timestamp in the semantic-memory output schema
- tell the extraction model to use conversation time when a fact has no
date of its own
- add a regression test for the assembled semantic prompt
This addresses the deterministic prompt inconsistency reported in
#18415. The invalid-timestamp fallback is intentionally left unchanged
because selecting its replacement policy requires a separate design
decision.

## Summary
Closes#6102
When using Infinity as the document store engine (GPU version), calling
`update()` on a non-existent table throws an unhandled
`InfinityException` with error code 3022 (`TABLE_NOT_EXIST`). This
causes users to see a raw "3022" error when clicking on a parsed
document.
## Root Cause
The `update()` methods in both `rag/utils/infinity_conn.py` and
`memory/utils/infinity_conn.py` call `db_instance.get_table(table_name)`
without catching `InfinityException`. In contrast, other CRUD methods
(`insert`, `delete`, `search`) all handle this exception gracefully:
| Method | Handles table-not-exist? | Behavior |
|----------|--------------------------|----------|
| `insert` | ✅ Yes | Auto-creates the table |
| `search` | ✅ Yes | Skips the table |
| `delete` | ✅ Yes | Returns 0 |
| `update` | ❌ **No** | Crashes with 3022 |
Additionally, `api/apps/document_app.py` worked around this with a
fragile string match (`"3022" in msg`) to detect the error.
## Changes
- **`rag/utils/infinity_conn.py`**: Catch `InfinityException` in
`update()`. When `TABLE_NOT_EXIST` is detected, log a warning and return
`False` — consistent with `delete()`.
- **`memory/utils/infinity_conn.py`**: Apply the same fix to its
`update()` method.
- **`api/apps/document_app.py`**: Remove the fragile `"3022"`
string-matching workaround. Table-not-exist is now handled by the `if
not ok` path with an improved error message.

Fixes#13823
## Problem
When querying with words like `cat`, RAGFlow's query expansion system
looks up synonyms via WordNet, which can return terms containing single
quotes (e.g., `cat-o'-nine-tails`). When using Infinity as the document
store, these unescaped single quotes in the query string cause a
`TokenError` because Infinity's lexer treats `'` as a string delimiter.
```
TokenError: Error tokenizing ' OR "big cat" OR "computerized tomography")^0.7)': Missing ' from 1:531
```
## Solution
Strip single quotes from synonym terms before they are inserted into
query expressions, consistent with how single quotes are already
stripped from the input query text (line 51 of `query.py`):
- **`common/query_base.py`**: In `sub_special_char()`, strip `'` before
escaping other special characters. This fixes the Chinese text
processing path and the `paragraph()` method.
- **`rag/nlp/query.py`**: In the English text path, strip `'` from
tokenized synonym terms.
- **`memory/services/query.py`**: Same fix for the memory query English
text path.
## Testing
The fix can be verified by:
1. Using Infinity as the document store (`DOC_ENGINE=infinity`)
2. Creating a dataset and running a retrieval test with the keyword
`cat`
3. Confirming no `TokenError` is raised and results are returned
normally

## Summary by CodeRabbit
* **Bug Fixes**
* Enhanced special character handling in query processing and synonym
expansion by properly sanitizing single quotes before text processing.
* Simplified OCR detection output by removing timing metadata while
preserving core detection accuracy.
