Work Summary

Focused on deployment readiness across frontend stability, backend compatibility, and reproducible model distribution. Resolved runtime import/config issues, fixed a critical config regression in backend routes, and completed a clean Hugging Face model bundle flow centered on a minimal .models structure.

• Frontend runtime stabilization:
  • Fixed $content import resolution and aligned alias usage.
  • Removed conflicting TypeScript paths overrides to match SvelteKit-generated config behavior.
  • Added missing site.webmanifest to remove manifest 404 failures.
  • Aligned core files: svelte.config.js, tsconfig.json, docs.ts, navigation.ts.
• Backend bootstrap and compatibility:
  • Implemented one-shot setup flow in setup.py.
  • Added package-level setup script and documented Railway volume persistence setup.
  • Fixed runtime crash AttributeError: 'Config' object has no attribute 'hf_repositories'.
  • Added compatibility properties for legacy route paths: hf_repositories, storage.
• Hugging Face bundle pipeline:
  • Refactored workflow script to backend/download.py.
  • Switched target path from .validate/ to .models/.
  • Enforced flat bundle layout and removed non-essential CLIP and dataset handling.
  • Final bundle includes MediaPipe face detector, MediaPipe landmarks, hat_beard_model.onnx, download.py, and auto-generated .models/README.md.
• Validation:
  • Ran --help and selective execution checks.
  • Verified successful uploads to both transition and final target paths.
  • Confirmed valid Hugging Face authentication state.

Learnings / Outcomes

• Small config mismatches can break full frontend runtime behavior.
• Backward-compatible fields are essential during config model evolution.
• Flat, scoped, self-documented model bundles are easier to distribute and maintain.
• Setup automation significantly reduces onboarding and deployment friction.

Blockers / Risks

• Blocker (resolved): frontend runtime import failures caused by alias/path mismatch.
• Blocker (resolved): backend crash due to missing legacy config property access.
• Ongoing risk: model version drift inside .models without explicit version/hash tracking.
• Ongoing risk: deployment failures if Railway volume setup is inconsistently applied.

Skills Used

SvelteKit, TypeScript configuration debugging, Python automation, Hugging Face Hub packaging, deployment hardening, backward compatibility design, Railway persistence configuration

Next Step

Add explicit model version/hash metadata to .models/README.md and wire setup bootstrap into CI/CD provisioning with a fallback download path.
