EverOS 1.3.1

One reproducible runner for four long-term-memory benchmarks, plus an
LLM-guided multi-round retrieval method. LoCoMo, LongMemEval, EverMemBench,
and SubtleMemory now share the same staged ADD → SEARCH → ANSWER → JUDGE
workflow, resume model, metrics, and run manifest. The new
llm_multiround search method iteratively recalls episode blocks, asks a
separately configurable decider to retain core evidence and issue follow-up
queries, and returns a bounded final context without a cross-encoder.

Added

• LLM-guided multi-round episode retrieval.
  POST /api/v2/memory/search accepts method = "llm_multiround" for user
  memory. Each round independently fuses BM25 and vector candidates for the
  current sub-queries with RRF, then uses the decider to select core evidence
  and identify remaining gaps. Existing search response fields are unchanged;
  decider failures are recorded in structured logs and optional trace dumps.
• Independent decider configuration. The new [decider] section selects
  the model, endpoint, timeout, request extras, retry policy, and loop tuning.
  Empty connection fields inherit [llm], preserving single-model setups.
• Unified benchmark harness. One runner and four adapters cover LoCoMo,
  LongMemEval, EverMemBench, and SubtleMemory with explicit dataset configs,
  resumable stage artifacts, deterministic run identities, shared IR metrics,
  decider preflight checks, and trace validation that rejects degraded
  multi-round runs before reporting scores.
• Cascade snapshot control. POST /api/v1/cascade/quiesce and
  POST /api/v2/cascade/quiesce drain the Markdown-to-index queue and stop the
  cascade subsystem until restart. Startup switches can disable all cascade
  work or only the filesystem watcher for managed read-only workloads.

Changed

• OME attempts are bounded. One strategy attempt now has a 1,800-second
  default wall-clock timeout and follows the existing retry/dead-letter path on
  timeout. Environment settings can tune concurrency or disable the timeout.
• SQLite pool saturation fails visibly. Pool size, overflow, checkout
  timeout, recycle, and pre-ping are explicit settings; exhausted pools now
  raise after a bounded wait and emit saturation diagnostics instead of waiting
  indefinitely.
• Extraction LLM transport is configurable. [llm] now exposes request
  timeout and provider-specific SDK arguments while retaining the previous
  60-second default.

Fixed

• Permanent embedding request errors no longer retry. HTTP 400, 401, 403,
  404, 413, 414, and 422 responses are classified as rejected input or
  configuration and leave the retry loop; timeouts, 429 responses, and server
  errors remain retryable.
• EverMemBench owner mapping no longer changes profile extraction. The
  adapter uses one stable synthetic owner per topic for both ingestion and
  search while preserving each real participant's name in message metadata.
  The production Profile cluster/direct extraction paths are unchanged.

Upgrade

pip install --upgrade everos   # or: uv sync

• No storage migration or index rebuild is required. Existing search methods
  keep their prior behavior unless callers explicitly select
  llm_multiround.
• Deployments with a healthy OME strategy that legitimately runs for more than
  1,800 seconds must raise EVEROS_OME_RUN_TIMEOUT_SECONDS or set it to 0 /
  off before upgrading.
