Problems & Solutions
Critical Issues
1. MIHD STAIG fusion results were byte-identical (silent failure) because raw HVG matrices bypassed gene encoder layers, invalidating benchmark data.
Solution: Confirmed integrity loss via md5sums; modified pipeline_config.yaml to enforce staig_gene_source='encoder'; archived corrupted outputs and reran SLURM jobs with correct paths.
Key Insight: Identical inputs to downstream GCNs mask upstream encoder errors; empirical binary verification (md5) is essential before accepting research outputs.
2. Accidental deletion and re-clone of MIHD folder wiped two months of uncommitted work and cached embeddings.
Solution: Identified NetApp .snapshot availability; used rsync to restore working tree, embeddings_cache, and configs from the daily snapshot (08:10 June 2); committed recoveries to GitHub.
Key Insight: Uncommitted HPC work is ephemeral; reliance on local trees without frequent commits or automated backups is extremely risky in shared/reclone environments.
3. AI Dev Companion build failed with TS5055 errors and /ccoverview translated crashed due to API timeouts/bloat.
Solution: Set root tsconfig ‘include’ to [] to fix workspace build; applied Fix C to /ccoverview: batched translation, switched to sequential execution, and added try/catch for timeout handling.
Key Insight: Payload size/concurrency drives LLM timeouts more than network latency; root tsconfigs in monorepos should often be pure references to avoid cascading module conflicts.
4. TokenMonitor Fork auto-update failed with 404/signing errors due to missing/uploader-pubkey.txt and incorrect macOS signing flags.
Solution: Generated new Tauri keypair, set correct base64 secret in GH Actions, and modified workflow.mjs to decouple minisign updater signing from Apple Developer ID requirements.
Key Insight: Updater signatures (minisign) and code-signing (Apple) are distinct; conflating them breaks cross-platform update consistency. Clean base64 secrets are critical for Tauri workflows.
General Issues
5. TokenMonitor dev server white screen and Hex-line MCP phantom config causing confusion.
Solution: Killed orphan Vite processes on port 1420; removed obsolete SessionStart hooks and output styles from Claude settings.json that mimicked MCP availability.
Key Insight: Vite strict port configs + improper shutdowns leave orphan processes; custom hooks can inject misleading UI messages that lack functional backing.
6. Research augmentation warp logic failed for Group A (grasp) with ~4% success due to orientation errors, despite fixing Group B (drop).
Solution: Applied position-only anchor warp to restore data; identified that Group A restoration is limited without ‘orientation-aware’ warp logic for specific face alignment.
Human vs AI Approaches
Strategic Level
Empirical Verification vs. Descriptive Confidence
| Role | Approach |
|---|---|
| Human | User demanded proof that build/test fixes actually worked, forcing a shift from code inspection to execution. |
| AI | AI initially claimed fixes were ‘working’ descriptively but failed to verify via npm test/build; upon pressure, it ran tests, found TS5055 errors and stale tests, and corrected them. |
Difference Analysis: Human skepticism exposed the gap between architectural intent and runtime state, uncovering bugs AI had glossed over by trusting its own code generation.
STAIG Fusion Architectural Correction
| Role | Approach |
|---|---|
| Human | User proposed ‘vector fusion’ of gene/image embeddings based on semantic understanding of the paper. |
| AI | AI corrected the premise, demonstrating that STAIG uses graph structural induction (edge weighting) and that the codebase already implements this via e2e_raw_expression, preventing misguided engineering. |
Difference Analysis: Human provided high-level goal/terminology; AI provided strict technical reality of the algorithm’s implementation constraints.
Signing Infrastructure Decoupling
| Role | Approach |
|---|---|
| Human | User identified that lack of Apple Developer ID certs shouldn’t block fork macOS auto-updates, as updater uses minisign. |
| AI | AI translated this insight into the specific workflow.mjs fix (disabling --no-sign only for Apple code, not minisign), enabling full multi-platform support. |
Difference Analysis: Human provided the architectural principle; AI executed the syntax and logic to decouple independent signing systems.
AI Limitations
General Limitations
- LLM wrapper implementations often crash on timeouts if not wrapped in try/catch, confusing them with JSON parse errors; this was a recurring pattern across projects today.
- Reliance on file metadata (dates/logs) over binary content (md5sums) initially masked the severity of data corruption in MIHD; required explicit artifact verification to prove byte-identity bugs.
- Failed to predict local environment differences (python3 vs python, Tauri key formatting) causing CI/release script failures, requiring manual iteration on secret formats and scripts.
Learnings
Key Learnings
- In spatial transcriptomics pipelines, verify embedding outputs with md5sums when comparing encoder branches; identical inputs to downstream GCNs can silently mask upstream failures.
- In HPC environments, always commit work frequently; local working trees are ephemeral and perilous if directories are re-cloned or deleted. System snapshots are a critical safety net but not a substitute for version control.
- Root tsconfigs in workspaces should often be ‘pure references’ (include: []) to avoid module resolution conflicts (CommonJS/ESM) that cascade into build failures.
Practical Learnings
- Tauri updater signing (minisign) and code-signing (Apple/DigiCert) are independent; conflating them in CI workflows breaks auto-update consistency for specific platforms.
- When using LLMs for structured data translation, explicitly enforce ‘preserve technical identifiers’ rules to prevent corruption of functional keys and paths.
