Problems & Solutions

Critical Issues

1. Gemini/VLM performance issues due to batching (v4) and prompt-induced verbatim repetition (priors).

Solution: Switched to ’trace1’ (one API call per frame) and removed coordinates from prompts, relying on post-hoc physical filters instead.

2. Multiple agents overwriting graph.yaml and graph.html due to lack of cross-process locking.

Solution: Implemented a lock-read-modify-write cycle protected by a short-term lock and an append-only event log.

3. Amber design assumption that ’typical dim-room backlight is 120 nits’ was incorrect; real measurements showed ~190 nits.

Solution: Updated documentation and code comments to distinguish between ‘pitch black’ targets (36 cd/m²) and ‘dim room’ practical usage.

4. Search-augmented solver suggested unsafe moves by assuming the visible board was the entire board.

Solution: Implemented a provable-safety filter that only suggests moves from groups with ≥3 visible icons.

5. Doc-code drift and incompatible idea graph formats across multiple projects.

Solution: Systematically updated documentation to match logic and used ‘ccscan’ to migrate from flat ‘step’ fields to hierarchical ‘parent’ ID relations.

6. Qwen3-VL’s Conv3d patch embedding was extremely slow (12.6s/frame).

Solution: Identified it behaves as a linear layer for the specific kernel/stride and patched with F.linear to reduce latency to 0.7s.

7. Loss of convergence in LMS when step-size r is too large.

Solution: Experimentally validated that r=1.0 diverges, confirming stability bound theory.

8. Self-attention architecture performed worse than pooling architecture during RL training.

Solution: Recognized that message-passing provides a strong structural prior for the icon-matching task, leading to faster convergence.

9. Agent cannot bypass ‘command header’ or ‘signed-off’ restrictions (D21/D26).

Solution: Designed manual workflows where users perform ‘destructive’ or ‘sign-off’ operations (like git reset/commit) while the agent handles the structured rebuild.

Human vs AI Approaches

Strategic Level

Amber Brightness Strategy

Role	Approach
Human	Questioned if existing brightness felt comfortable and if the 36 cd/m² target was context-dependent.
AI	Initially suggested lowering the coefficient, but later pivoted to adjusting documentation once the human’s intuition about comfort was validated by data.

Difference Analysis: The human correctly identified that subjective comfort and scientific targets (DLMO/cortisol) are two different optimization goals.

VLM Grounding Capability

Role	Approach
Human	Hypothesized that Gemini’s failure was due to batching constraints rather than an inability to ground.
AI	Initially interpreted previous failures as a fundamental lack of grounding capability in the model.

Difference Analysis: The human correctly identified the methodological flaw (batching) that led to the AI’s incorrect conclusion about model capability.

Coordination Strategy

Role	Approach
Human	Proposed an innovative idea of using a shared log file acting like a forum/group chat (Slack/WeChat) to allow agents to communicate and coordinate via locks.
AI	Initially focused on technical file-level locking and directory separation, but then pivoted to refine the human’s ‘shared message board’ idea into a structured implementation plan.

Difference Analysis: The human provided the high-level social/communication metaphor, while the AI provided the technical execution details (lockfile, event log, session ID isolation).

LMS Convergence Analysis

Role	Approach
Human	Provided the task requirements and verified results based on specific target outputs.
AI	Analysed the relationship between the step-size ‘r’ and the steady-state error/divergence to explain why large ‘r’ values fail.

Difference Analysis: The AI successfully synthesized the mathematical reason for the divergence (step size vs stability bound) based on the empirical output.

Idea Tree Governance

Role	Approach
Human	Human defined strict constraints on idea hierarchy (max 7 children per level) and prevented AI from fabricating ‘why_this_way’ reasons.
AI	AI attempted to perform the scan but was corrected on command syntax and strict adherence to the manual verification process.

Difference Analysis: The human enforced a ’no-hallucination’ policy for technical documentation, ensuring the graph only contains verified facts.

git commit automation

Role	Approach
Human	N/A
AI	Attempted to automate via bash.

Difference Analysis: The Guard (D21) enforces that only humans sign off on history-changing commands like git commit. I have staged all changes and provided the exact commit message for the user.

Manual verification and signing

Role	Approach
Human	Execute request-approval --gate manual-check and sign off items.
AI	Can only propose changes and prepare ’envelopes’ for human approval.

Difference Analysis: The human provides final verification and authority while the AI manages complex graph-theory constraints.

AI Limitations

Critical Limitations

• AI failed to realize that high winding accuracy (topology) does not guarantee policy success if geometric error (precision) is too high.
• AI initially suggested a solution (lowering brightness coefficient) that would have compromised user comfort based on a flawed assumption.
• AI initially overlooked the potential for ’lost updates’ in the YAML file where agents read an old version and overwrite newer changes made by others.
• The agent cannot bypass the ‘command header’ restriction in guard.ts. Even if the intention is benign, execution is denied to preserve human accountability.
• The agent cannot self-approve or manually set status to ‘done’ without valid external evidence and human-triggered approval events.

General Limitations

• AI struggled with segmenting obscured ‘slivers’ of tiles due to overlapping connected components in image processing.
• AI attempted to chain commands (&&/;) which were explicitly prohibited by the companion guard/skill rules.
• AI assumed ‘jupyter’ was installed in the environment to run the notebook, requiring a fallback method.
• The AI cannot ‘skip’ the guard rule for signed nodes; any attempt to delete them is rejected by the engine.
• Maximum token limits prevented reading the entirety of large files in single chunks, requiring strategic offset-based slicing.

Learnings

Key Learnings

• Geometric precision is as critical as topological correctness; a high winding accuracy can still result in 0% Success Rate if chamfer error is too high.
• Exact rollout search can turn a mediocre/unreliable RL policy into a near-perfect decision maker in deterministic environments.
• Zero-initialization in CNNs for ReLU networks can lead to ‘dead’ networks where gradients are blocked due to zero weights and zero activations.
• In circadian design, there is a fundamental tension between ‘sleep optimization’ (low light) and ‘visual comfort’ (matching ambient light).
• In LMS, larger step sizes (r) speed up initial convergence but increase the variance of the weights around the optimum, leading to higher steady-state error.
• For multi-agent environments, a ‘social’ layer (shared messaging) is as important as a ’technical’ layer (file locks) to allow intent sharing.
• The codebase relies heavily on a ‘Pricing Version’ to invalidate caches, serving as a critical sync point between Rust and Svelte.
• The ‘containers idea’ pattern significantly reduces cognitive load in the graph view by preventing top-level idea bloat.
• The ‘rebuild’ method is the only way to clean up a messy graph where ID logic has fragmented, but it creates a significant manual task in restoring ‘done’ status.
• RED mechanism necessity: If an idea does not have a corresponding pytest or failing command, it cannot support a ’test-first’ development loop.

Practical Learnings

• The ‘unanswered how’ edit significantly improved the graph’s practical utility for future planning.
