Tasks
Architecture & Strategy
- ✅ Advisor Reputation Audit (Top 50) — Conducted an exhaustive multi-phase workflow audit of hundreds of professors to filter for advising style, program protection, and research alignment.
- 🔄 Complete LIBERO evaluation — Finish all four suites (spatial, object, goal, 10) and aggregate the success rates for quantized pi0.5.
- • Final Success Rate Report — Compare W4A4 success rates against the float baseline and document any failure modes.
- 🔄 Implement Error Definitions (H1, H2a, H2b, H5a, H5b) — Implement and adversarially verify new definitions for scanned recorded states, contact-based collisions, and task regression.
- ✅ Retraining Plan (G1) — Developed a full retraining matrix including model/task/condition runs and verified base weights for Pi0.5 and OpenVLA.
- ✅ WeChat Channel Integration (Portal-side) — Implement channel token authentication and specific route permissions for non-human callers (WeAgent/MCP) to ensure security while allowing access to plan/mood/task routes.
- 🔄 WeAgent Plugin Development — Developing the actual AstrBot plugin in the external WeAgent repository.
- ✅ WeAgent LifeCopilot Integration — Implemented Phase 5: LifeCopilot entry, including new configuration schema, HTTP client logic, owner verification, and command handling for plan approval/rejection.

Problems & Solutions
Critical Issues
1. Pi0.5 model output variances observed after integration.
Solution: Diagnosed as XLA GPU autotuner (Triton GEMM) non-determinism in the JAX compilation cache rather than a code regression.
2. Concurrency issues in draft approvals leading to duplicate calendar events.
Solution: Refactored the approval flow to first mark old drafts as ‘rejected’ and push their changes before finalizing the approved draft.
3. LifeCopilot integration risked breaking WeChat connectivity during auto-restarts.
Solution: Implemented strict variable isolation, used asyncio.to_thread for HTTP calls, and ensured pre-deployment compilation.
4. TokenMonitor cannot read usage for the new OpenAI GPTdot feature.
Solution: Probed the local Codex app-server API using chat IDs to attempt thread-specific usage retrieval.
5. Discrepancies between F1, G1, and B7 reports found by the critic agent.
Solution: Initiated follow-up fixup workflows to reconcile the retraining run list and link the demo audit properly to downstream trackers.
6. Non-ASCII credentials failed during Bearer authentication due to encoding mismatch.
Solution: Implemented byte-level comparison for tokens and ensured the validator rejects non-ASCII secrets at startup.
7. Workflow execution error: writer-agent stage in advisor audit failed, causing truncated files.
Solution: Developed and ran a custom Python script to rebuild school-specific evidence files from original workflow journal logs.
8. Potential for accidental EC2 termination instead of stop during idle-shutdown.
Solution: Implemented a safety check mechanism and provided explicit warnings in the AWS Console.
9. Benchmark’s operator kit has a bug where self-tests and human recordings share the same directory.
Solution: Developed a patch to isolate self-test outputs from human-recorded demonstrations.
General Issues
10. Incorrect technical quantity (136 vs 24 error subtypes) in CV/application files.
Solution: Executed a global search and replace across the entire repository to ensure consistency.
11. MIHD N-03 configuration incorrectly listed UCE as a ‘blocker’.
Solution: Modified the N-03 row overlay and analysis scripts to reflect UCE as excluded.
12. CV content was too descriptive/passive, weakening perceived impact.
Solution: Adopted a ‘bold and active’ strategy using impact-driven verbs and placing key results at the start of bullet points.
13. Uvicorn startup failed to return specific exit codes or handle Ctrl+C gracefully.
Solution: Wrapped uvicorn server execution in a try-except block to capture startup errors and manage signals.
14. GPU OOM during evaluation due to resource contention.
Solution: Manually migrated the libero_10 suite to GPU 2 to avoid conflict with libero_goal on GPU 0.
15. In Hyper-V ‘Enhanced Session Mode’, closing the window locks the desktop, impacting UI automation.
Solution: Switch to ‘Basic Session’ before closing or simply minimize the window to keep the desktop active.
Human vs AI Approaches
Strategic Level
Error Recovery Mechanism Design
| Role | Approach |
|---|---|
| Human | Proposed decomposing compound continuous errors into specific, fine-grained atomic ‘Error Skills’. |
| AI | Identified this as a key strategic design decision differentiating the work from existing approaches. |
Difference Analysis: Human provided the research intuition; AI framed it for high-impact writing.
Error Definition Implementation
| Role | Approach |
|---|---|
| Human | Defined specific physical thresholds (e.g., real collision vs. gripper-object contact, intended motion vs. pause). |
| AI | Attempted to implement these as code-level changes and automated verifiers. |
Difference Analysis: The human provided the conceptual physical rigor which the AI had to translate into programmatic logic.
Project Architecture: WeChat as a Port
| Role | Approach |
|---|---|
| Human | Proposed using the existing WeAgent (AstrBot plugin) as a seamless third channel for LifeCopilot. |
| AI | Researching AstrBot’s internal plugin registration and toolset management to support the user’s vision. |
Difference Analysis: The human drove the strategic direction, while the AI provided technical feasibility research.
GR00T Model Observation
| Role | Approach |
|---|---|
| Human | Noted that GR00T fails in specific error-recovery scenarios despite arbitrary start-point success. |
| AI | Synthesized this into the hypothesis: ’error-after-state’ is distinct from ‘arbitrary starting state’. |
Difference Analysis: Human provides empirical nuance; AI converts it into academic logic.
Minecraft Server Control Strategy
| Role | Approach |
|---|---|
| Human | Requested a remote control method that includes password protection and status checking. |
| AI | Proposed a Lambda-based ‘Secret Link’ approach with IAM role-based access control. |
Difference Analysis: Human focused on user experience; AI focused on security and cost architecture.
CV Strategy
| Role | Approach |
|---|---|
| Human | Suggested the CV should be ’extravagant/bold’ to better showcase strength. |
| AI | Pivoted from a conservative approach to a strategic ‘boldness’ through high-impact verbs. |
Difference Analysis: Human provided the psychological direction; AI translated it into writing tactics.
AI Limitations
Critical Limitations
- Difficulty in reconciling cross-agent data consistency without explicit global synchronization.
- Automated file writing stage failed during a complex multi-agent workflow, requiring manual reconstruction from logs.
General Limitations
- AI initially attempted to write to an external repository (WeAgent) which was blocked by project guardrails.
- Cannot prevent physics engine crashes or hardware-level OOMs directly, but can reactively reschedule tasks.
- Agent workflow failures due to hitting API/rate limits.
- Difficulty executing multi-command bash strings due to environment restrictions; required manual decomposition.
- Initial failure to distinguish between ‘accuracy’ and ‘methodological impact’ in CV suggestions.
Learnings
Key Learnings
- When handling multi-channel systems, authentication must differentiate between human users and automated agents for scoped access.
- Project restructuring is safer when using a read-only ‘Scout-and-Design’ workflow before moving files.
- Reliable robot learning must distinguish between ‘arbitrary starting state’ and ‘state following an execution error’.
- Robust error definitions require distinguishing between trivial physical changes and meaningful task state regressions.
- When integrating external APIs into a reactive bot, strict identity verification (using wxid) is essential for security.
- For personal Pro accounts, standard APIs might return null for thread-specific data, requiring local CLI probing.
- GPU kernel autotuning can introduce subtle numerical differences that mimic code regressions.
Practical Learnings
- The TMPDIR must be explicitly set to a directory on /home to avoid filling the / partition during QuantSim ONNX exports.
- Hyper-V ‘Enhanced Session’ is essentially RDP (locks on close); ‘Basic Session’ keeps the desktop running.
