Add registered fusion and site batching, decision reuse, independent extraction, and incremental runtime state optimizations. Introduce explicit Zep fact-summary and representative variants, benchmark accounting and answer validation, and offline regression tests. Correct fusion-version provenance across all registered strategies. Signed-off-by: Von <haodong.lu.me@gmail.com>
…ance Collect iteration-level design notes and add a branch review map. Separate physical execution strategies from logical Zep variants, document recovery and retry limits, and state the offline validation boundary. Signed-off-by: Von <haodong.lu.me@gmail.com>

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe PR adds Zep memory strategies, Lotus physical fusion and site-specific batching, incremental runtime execution, parallel fact extraction, benchmark contract updates, and frozen Zep experiment tools. ChangesZep memory execution and runtime maintenance
Frozen Zep experiments
Priority: ⬇️ Low Estimated code review effort: 5 (Critical) | ~90 minutes Change: Feature Merge Risk: 🔵 Low · up to This experimental branch adds many opt-in execution optimizations. One narrow issue remains: if a policy that was already prepared with predicate reuse is prepared again, setup fails with an error. Default behavior is unaffected. The fix is small and can be made as a follow-up. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The optional changes affect stored information and recovery. Reviewed paths contain failures and reject incompatible recovery; no increased access or authority was demonstrated. Shared-use isolation and live-service behavior remain unverified.

Review comments at @src/agent_memory/adapters/lotus/context.py:
- Around line 282-302: Serialize initialization in
LotusExecutionContext.configure() so concurrent calls cannot both pass the
_configured check and install different LOTUS wrappers. Guard the check and
configuration with a lock, and publish _lm, _scoped_lm, and _configured only
after lotus.settings.configure() succeeds; ensure fork() copies the wrapper that
is active in global settings.
- Line 342: Update the LM-wrapper selection condition so
`groupby_prompt_batching` also enables the provider-usage wrapper, alongside the
existing batching settings. Locate the condition in the context setup and
preserve its current behavior for all other options.
Review comments at @tools/zep_frozen_followup.py:
- Around line 297-298: In the run failure handler, update the save call for
status.json to write the failed status only when args.output / "status.json"
already exists; otherwise leave the output directory untouched. Preserve the
existing exception propagation.
