Bug: Surprisal filter format error - should use {"in": [...]} syntax

[Fengqx2022]

Description

The Surprisal module in src/dreamer/surprisal.py line 264 uses an incorrect filter format when calling get_all_documents().

Problem

# Current code (incorrect)
filters = {"level": levels}

This format is not recognized by the apply_filter function in src/utils/filter.py, which expects:

# Expected format
filters = {"level": {"in": levels}}

Impact

When Surprisal tries to filter observations by level, it returns 0 results, causing:

• Surprisal computation to fail silently
• Dream cycle to skip the Surprisal phase
• No high-surprisal observations are identified

Fix

Change line 264 in src/dreamer/surprisal.py:

# Before
filters = {"level": levels}

# After
filters = {"level": {"in": levels}}

Environment

• Honcho version: latest (commit from April 2026)
• Python: 3.11+

Verification

After fix:

docker compose up -d --build deriver
docker exec honcho-deriver-1 python -c "
from src.dreamer.surprisal import get_surprisal_observations
import asyncio
result = asyncio.run(get_surprisal_observations(workspace='test', peer_id='test'))
print(f'Found {len(result)} high-surprisal observations')
"

Should return non-zero count of observations.

Related

This bug was discovered during practical testing with SURPRISAL_ENABLED=true. The fix was verified with a complete Dream cycle that successfully identified 15 high-surprisal observations from 152 total.
