Three S-effort wins from the post-migration audit:
#1 Enable Cohere reranker on both Memory.search call sites
(rerank=True), over-fetch top_k=max(limit*3, 30) to give the
reranker a 30-50 candidate pool, then truncate to the caller's
limit. Bump reranker config to rerank-v3.5 (4096 ctx, multilingual
— matters for Hindi/Hinglish traffic) and top_n 10 → 50 so the
output cap doesn't truncate below typical over-fetch sizes. Cohere
was configured but never invoked; this is the single biggest
quality lift the audit surfaced.
#2 Add scripts/backup_qdrant.sh and scripts/restore_test.sh. Daily
snapshot of both collections back-to-back, docker cp to local
YYYY-MM-DD dir, optional rclone off-host, prune local >14d, emit
Prometheus textfile metric. Weekly restore_test.sh restores into a
transient collection and asserts point count parity. Closes the
zero-automated-backup gap.
#3 Add CUSTOM_FACT_EXTRACTION_INSTRUCTIONS, wired via MemoryConfig's
custom_instructions field. mem0 appends this as its own
'## Custom Instructions' section in the additive-extraction user
prompt (verified against generate_additive_extraction_prompt) —
does not replace mem0's role/format guidance. Re-prioritizes the
default consumer-organizer few-shots toward work/projects/
relationships/recurring context, the actual usage pattern here.
