What Changed

Runtime + Model Baseline

• B baseline model defaults moved to qwen3.5:9b for task workers/runners.
• Ollama container image pinned to 0.18.1 with OLLAMA_IMAGE override support.

Agent Retrieval Flow

• Added pre-inference context expansion runtime:
  • POST /memory/context-pack preflight
  • layered context (L0 facts, L1 rollups, L2 raw refs)
  • broadened scope retry
  • deep async continuation polling
  • fail-open behavior with lifecycle visibility
• Added post-inference checkpoint writeback for task workers and generic runners.
• Added retrieval lifecycle metadata and pending-source visibility in task status/feedback flow.

Codex Integration Hardening

• Added stable agent identity defaults:
  • CONTEXTLATTICE_AGENT_ID=codex_gpt5
  • MEMMCP_AGENT_ID=codex_gpt5
• Added codex-first CLI preflight in scripts/agent_orchestration.py:
  • health/status check
  • scoped search with broadened fallback
  • context-pack retrieval
• Added context-pack CLI command in scripts/agent_orchestration.py.

Endpoint Consistency

• Agent instruction surfaces now pin external orchestrator endpoint guidance to:
  • http://127.0.0.1:8075
• Added explicit default env examples for:
  • MEMMCP_ORCHESTRATOR_URL
  • CONTEXTLATTICE_ORCHESTRATOR_URL

Validation and Tests

• Added/updated tests for:
  • context expansion runtime behavior and deterministic slicing
  • stable agent-id propagation into retrieval payloads
  • context-pack integration in orchestration helper
• Environment lock validation updated and verified.

Compatibility Notes

• The public orchestrator endpoint remains :8075.
• Rust + Go remain the default runtime path, with Python fallback still present.
• This release does not include V4 backend replacement/cutover changes.
