Tasks

Architecture & Strategy

• ✅ Data Migration (XYFS01 to XYFS02) — Migrated RoboMemory and ErrorRecoveryBenchmark datasets (including massive pkl files) and multiple Conda/venv environments to the new XYFS02 partition, including fixing 576 broken symlinks and patching rsync dependencies.

Problems & Solutions

Critical Issues

1. Repository ‘companion guard’ (D16/D28) produces zero output, causing a ‘fail-closed’ policy that blocks all agent writes and shell commands.

Solution: Identified the need for manual IDE intervention to add explicit JSON ‘allow/deny’ responses and implemented JSON error messaging/stdin timeouts for the guard.

2. Inaccurate PhD SoP content due to outdated faculty information (e.g., moves, sabbatical).

Solution: Used adversarial verification agents to cross-reference faculty directories, personal sites, and news to correct the database.

3. Existing idea graph had high complexity and disconnected nodes.

Solution: Proposed a simplified 32-node architecture merging mechanisms into a single main path.

4. Inefficient migration of 477k small pkl files using single-stream rsync (~4 hours).

Solution: Implemented an 8-way parallel rsync strategy by splitting files by name prefixes, reducing time to ~1 hour.

5. Redundancy in PhD SoP (repeating specific datasets in every paragraph).

Solution: Implemented a rule in the SOP outline to use ‘back-referencing’ instead of re-stating core numbers.

6. Gemini API calls failing via tunnel due to frequent jump-host connection drops.

Solution: Shifted the Gemini workload from the remote supercomputer to the local laptop for reliable campus network proxying.

7. Workflow agent attempt to use Google Translate for project text was blocked by security policies.

Solution: Re-routed the translation task to a local Ollama instance running Gemma 4.

8. AI attempted to update tests before engine implementation was recorded, causing ‘unexpected_pass’ (red-waiver needed).

Solution: Used a ‘red-waiver’ to bypass the guard, then correctly sequenced engine changes and test path updates.

General Issues

9. System lag despite low CPU/GPU usage due to DWM compositor contention between Electron apps and virtual monitors.

Solution: Uninstalled uxplay and Amyuni USB Mobile Monitor drivers to clear the display stack.

10. Rsync command not found on the new partition due to missing binaries and shared library dependencies.

Solution: Manually copied the rsync binary and its required shared libraries (libpopt, libxxhash) to the new miniconda directory.

11. Density of VLM memory tracks was insufficient (only 24 sampled frames).

Solution: Re-ran the tracking script to perform one Gemini API call for EVERY single demo frame to create a dense path.

12. SSH configuration error causing loss of connectivity due to a typo in a comment line.

Solution: Corrected the configuration block to properly separate the tianhe3-proxy host and restored the comment symbol.

13. Reverse tunnel ports being held by stale/dead SSH sessions.

Solution: Implemented a self-healing tunnel loop that automatically finds and occupies the next available port.

14. Integration test failure regarding FORMAT.md sync.

Solution: Identified that the local environment needed a fresh installation via npx tsx companion/install.ts . to propagate changes.

Human vs AI Approaches

Strategic Level

System Architecture Design Principles

Role	Approach
Human	Demanded a focus on ‘preserving outcomes, not mechanisms’, prioritizing modularity, simplicity, and logical clarity over speculative abstraction.
AI	Initially focused on auditing existing nodes or presenting disconnected ‘capability inventories’ without a coherent runtime flow.

Difference Analysis: The human provided the strategic/philosophical constraints (Simplicity/Modular/Not-Over-engineered) which transitioned the AI from an auditor to a designer.

Application Strategy: Breadth vs. Depth

Role	Approach
Human	Questioned if being ‘all-in’ on VLA is risky and suggested looking for broader, established faculty to mitigate risk.
AI	Argued that the SoP should remain ’narrow’ for fit, proposing a ‘70/30’ split between narrow/high-ceiling and broad/stable targets.

Difference Analysis: The human identified a strategic vulnerability (over-specialization) that the AI’s initial scoring system had structurally ignored.

Memory Task Classification

Role	Approach
Human	Defined a custom four-quadrant logic: (Arm vs. Object) x (Before/Demo vs. During/Execution).
AI	Initially relied on existing simplified classification which missed temporal and actor-based distinctions.

Difference Analysis: The human provided the conceptual framework that turned a simple tracker into a systematic memory agent.

Security implementation vs. Test sequencing

Role	Approach
Human	Identified that the AI’s test-first approach caused a logic deadlock where the engine blocked ‘green’ status due to a stale red record.
AI	Attempted to fix tests by editing files, which invalidated previous ‘red’ logs, requiring a manual ‘red-waiver’.

Difference Analysis: The human provided the necessary tactical decisions (approving waivers/signatures) to navigate the AI’s automated guardrails.

Implementation of Portal Proxy

Role	Approach
Human	Discussed the need for the portal to manage multiple repositories with a unified entry point.
AI	Identified that the engine’s absolute URL paths (/changes) would break standard path-prefix proxying and proposed injecting JS to rewrite fetch calls.

Difference Analysis: The AI identified a specific technical implementation obstacle (absolute vs relative paths in proxying) not in the original plan.

Command Execution & Tool Use

Role	Approach
Human	Instructed the AI on specific shell behaviors regarding redirection and command-head recognition.
AI	Attempted to use command chaining (semicolons) which triggered the guard’s safety protocol.

Difference Analysis: Human knowledge of the specific ‘companion’ guard rules allowed the AI to correct its tool-calling pattern.

AI Limitations

Critical Limitations

• The agent struggled to execute file writes or shell commands because it couldn’t diagnose the ‘fail-closed’ security hook without user intervention in the IDE.
• The assistant attempted to use an external web service (Google Translate) for sensitive project text, which violated security protocols.
• AI caused a logic deadlock by modifying test files after a ‘red’ state was recorded, making the record ‘stale’ and blocking implementation.
• AI initially failed to recognize that the engine’s ‘serve’ command lacked the ‘–git-sync’ flag, causing silent failure in the sync workflow.

General Limitations

• The AI’s command for running the writer script had a path inference bug that caused multiple task failures.
• AI’s grep commands were initially too broad (substring matches), leading to incorrect counts in the audit report.

Learnings

Key Learnings

• A ‘Four-Quadrant’ classification (Who moves x When it moves) is a highly effective prompt structure for VLM memory generation.
• For high-stakes writing (SoP), the ‘generic core’ must be robust enough to bridge multiple distinct ‘customized hooks’ to prevent logical drift.
• Funding is often guaranteed by the institution, but research resources (robots/GPUs) are strictly advisor-dependent; diversifying advisors is more critical than diversifying research topics.
• Complexity in system design often stems from ‘unclaimed ideas’ in documentation; a strict implementation of the ‘8-question’ framework for all new ideas is necessary.
• When migrating large numbers of small files (pkls), parallelization by filename-prefix is significantly more efficient than standard directory-tree rsync.
• Visual prompting requires task-specific markers (path, ring, badge) rather than a unified rendering primitive to avoid ‘false memory’ errors.

Practical Learnings

• When migrating environments, copying binaries is insufficient; RPATH and shared library dependencies must be verified and moved together.
• Using a local LLM (Gemma 4) for high-volume text translation (130k+ characters) is viable for maintaining data sovereignty in technical projects.
• Low CPU/GPU utilization does not rule out system lag; DWM compositor contention and high-resolution scaling (4K) can cause significant frame latency.
