Weekly Report — 2026-W36 (2026-08-31 ~ 2026-09-06)

This week was characterized by a massive architectural shift towards hierarchical project management and high-precision AI agent governance. Key achievements include the successful implementation of a unified AI-companion engine with a hierarchical ’thought tree’ structure, the migration of multiple major repositories (LifeCopilot, RoboMemory, etc.) to this new core, and significant breakthroughs in robotic vision via the ’trace1’ per-frame localization strategy. The week also involved critical hardware diagnostics for PCIe stability and the development of a high-performing RL solver for mobile tile games, transitioning from level-specific models to a single, generalized, permutation-invariant architecture.

Project Progress

AI Companion (Unified Base) (6 days active) — 🔄 active

Accomplishments:

  • Implemented hierarchical thought tree architecture (max 7 items per level)
  • Developed content-bound per-idea approval mechanism to reduce approval fatigue
  • Successfully migrated 7+ repositories to the new shared base
  • Implemented loopback service protection and multi-agent coordination protocols

Blockers:

  • ⚠️ Guard hook (D21) returning no output causing fail-closed blocks
  • ⚠️ Missing ‘beforeReadFile’ hook in Cursor configuration

RoboMemory & VLM Research (5 days active) — 🔄 active

Accomplishments:

  • Implemented ’trace1’ per-frame localization for high-precision trajectory tracing
  • Developed Qwen3-VL SFT dataset (200 samples) with proprioceptive oracle sidecars
  • Optimized Qwen3-VL backend by replacing Conv3d with F.linear to resolve latency
  • Verified 512GB RoboMME datasets on Tianhe3 cluster

Blockers:

  • ⚠️ VLM semantic/temporal mismatch in batch-mode processing

Mobile Tile Game RL (2 days active) — 🔄 active

Accomplishments:

  • Developed vision pipeline (AirPlay capture/pixel clustering)
  • Transitioned from level-specific models to a single permutation-invariant message-passing architecture
  • Integrated search-augmented rollout strategies for real-time decision making

Blockers:

  • ⚠️ Convergence challenges in harder game levels

Qualcomm NPU Optimization (2 days active) — ✅ completed

Accomplishments:

  • Corrected quantization latency profiles (A4 penalty identified at +29%)
  • Determined lack of Int4 activation paths necessitates block quantization strategy

Amber (Circadian Design) (2 days active) — 🔄 active

Accomplishments:

  • Analyzed night logs to verify brightness targets
  • Updated design documentation to distinguish between pitch-black and ambient room targets

Key Tasks

  • Implement Unified AI-Companion Engine (I-088/I-089) — Ported the Claude idea-graph engine to a neutral ‘companion’ directory with readiness checks and 27 verified tests; evolved into a hierarchical thought tree system.
  • 🔄 RoboMemory V6 Architecture Implementation — Implementation of the ‘Look-Record-Draw’ loop including JSON schemas and per-chunk dual-call logic.
  • Real-world Game Solver Implementation — Integrated search-augmented rollout strategy for real-time pattern recognition in mobile games.
  • VLM Trace1 Implementation & Optimization — Developed per-frame Gemini detector and optimized Qwen3-VL backend via F.linear patching.
  • Qualcomm VLA Quantization Profiling — Validated W8A8 feasibility and corrected the much larger than expected A4 latency penalty due to ‘compute explosion’.
  • AI Companion Security Audit — Executed 66+ agent adversarial audit to identify P0 blockers in shell injection and patch parser vulnerability.

Problems & Solutions

1. Security Bypasses in AI Companion (Prompt Injection/Patch Vulnerabilities) [AI Companion]

Solution: Recommended blocking production activation until guard whitelisting and strict field restrictions are enforced.

2. VLM performance degradation during batching/repetition [RoboMemory]

Solution: Implemented ’trace1’ mode (one frame per API call) and removed coordinates from prompts to rely on post-hoc physical filters.

3. Misleading A4 quantization latency metrics [Qualcomm VLA]

Solution: Re-profiled with consistent weights against matched W4A8 expert, revealing true +29% cost driven by compute explosion.

4. Windows connection timeouts/path issues in VS Code/Codex [Infrastructure]

Solution: Fixed by using bare ‘ssh’ command in ProxyCommand and setting ‘remote.SSH.connectTimeout’ to 300s.

5. Agent approval fatigue from whole-graph snapshots [AI Companion]

Solution: Implemented granular, content-bound approval digests for individual node IDs.

Learnings

Architecture (architecture)

  • Hierarchical data visualization (parent-child trees) is superior to flat lists for preventing information paralysis in complex project management.
  • Permutation-invariant policies require message-passing or attention mechanisms to allow items to ‘sense’ each other’s presence/counts.

Debugging (debugging)

  • Geometric precision is as critical as topological correctness; high winding accuracy cannot compensate for high chamfer error in robotics.

Domain Knowledge (domain)

  • High-precision trajectory tracing requires per-frame localization (grounding) rather than batch-style reasoning due to temporal correspondence issues.
  • In multi-agent environments, a ‘social’ layer (shared messaging) is as vital as a ’technical’ layer (file locks) for coordination.

Tools (tools)

  • In Windows environments, always resolve executables via ‘shutil.which’ or absolute paths to avoid PATHEXT resolution failures in subprocesses.

AI Usage Notes

Effective Patterns:

  • ✓ Adversarial multi-agent audits (66+ agents) for security/integrity verification
  • ✓ Red-Green-Refactor TDD for core engine porting
  • ✓ Using AI to generate empirical proofs (e.g., CDP click vs human click experiment)

Limitations:

  • ✗ Guardrail interference: AI cannot execute ‘destructive’ commands like git commit or shell redirection due to strict security policies.
  • ✗ Documentation lag: AI occasionally uses outdated workflows because it cannot self-validate prose in README/FORMAT files against current code.

Next Week Outlook

Priority 1: Resolve the AI Companion guard hook ‘failClosed’ issue and connect ‘beforeReadFile’ to unblock ccscan. Priority 2: Advance RL Architecture to Transformer-based (Self-Attention) for improved SheepEnv reasoning. Priority 3: Finalize the ‘Why’ and ‘Future’ vision gaps in rebuilt hierarchical graphs. Priority 4: Continue VLM evaluation with ’trace1’ and finalized Qwen3-VL SFT datasets.
