ContextLattice v3.3.0

This release includes all updates merged since v3.2.16.

Commit Delta Since v3.2.16

• c417d22 — fix(public): keep explicit source reads fail-open and document async access pattern (#119)
• 718908e — sync(public): port agreed issue96 Go/Rust and memory-bank enhancements (#120)

What Changed

1) Retrieval UX integrity: explicit-source fail-open

From #119:

• Explicit source requests on /memory/search now remain fail-open by default (unless blocking=true or sync_slow_sources=true).
• Staged fetch behavior is preserved for explicit source selection.
• Successful responses now consistently return continuation metadata instead of hard transport timeout failure patterns.
• Access-pattern docs were updated to include /v1/memory/neighbors and staged async guidance.

Files updated in #119:

• services/gateway-go/main.go
• services/gateway-go/main_test.go
• README.md
• docs/human_agent_instruction_playbook.md
• docs/public_overview/templates/AGENTS.contextlattice.md

2) Public Go/Rust cutover tranche + memory-bank upgrades

From #120:

• Ported agreed dev/paid enhancements into public free runtime.
• Expanded Go-owned runtime surfaces in gateway-go so critical memory/search paths are Go-native.
• Added memory-bank B2 preset controls and hedge wiring.
• Added C2 duplicate-history reduction/compaction logic in gateway memory store.
• Added/updated phase-B soak monitor scripts and hardening for long-running launcher behavior.
• Fixed benchmark attribution under strict Go runtime.

Primary runtime/config updates from #120:

• services/gateway-go/main.go
• services/gateway-go/main_test.go
• services/gateway-go/memory_async_status.go

• scripts/start_phase_b_step5_soak.sh
• scripts/stop_phase_b_step5_soak.sh
• README.md

Validation Summary

• cd services/gateway-go && go test ./...
• bash -n scripts/start_phase_b_step5_soak.sh
• python3 -m py_compile scripts/retrieval_soak_monitor.py scripts/retrieval_soak_summary.py

Operational Outcome

• Public lane now includes the agreed Go/Rust cutover enhancements and memory-bank controls from the paid/dev track subset selected for public stability and integrity.
• Async/staged retrieval behavior for explicit-source reads is more robust and user-safe under load.

Performance Delta vs v3.2.16

Benchmark scope:

• Workload: explicit-source retrieval (topic_rollups,memory_bank,letta)
• Modes: balanced,deep
• Base URL: http://127.0.0.1:8075
• Soak duration: ~72s per release run
• Harness: scripts/retrieval_soak_monitor.py + scripts/retrieval_soak_summary.py
• Baseline: v3.2.16 (505bf94), Current: v3.3.0 (718908e)

| Metric | v3.2.16 | v3.3.0 | Delta | Speedup |
|---|---:|---:|---:|---:|
| balanced p95 (ms) | 9611.589 | 70.029 | -9541.560 | 137.25x |
| balanced p99 (ms) | 13739.844 | 92.044 | -13647.800 | 149.28x |
| deep p95 (ms) | 10063.372 | 45.582 | -10017.790 | 220.77x |
| deep p99 (ms) | 14386.592 | 51.450 | -14335.142 | 279.62x |
| overall degraded rate | 0.125 | 0.000 | -0.125 | n/a |

Interpretation:

• Tail latency improved substantially in this retrieval path.
• Degraded responses in this test path dropped from 12.5% to 0%.
• This aligns with the explicit-source fail-open and Go/Rust runtime cutover tranche included in this release.
