2a7024a — Add model comparison demo + fix Volume env isolation

New comparison page at /comparison for side-by-side streaming across all 6 models: Gemini, Claude, OpenAI (teachers) and TS_Modal (31B), TS_mobile4B (E4B), TS_mobile2B (E2B) with version selectors. Uses existing SSE multiplexing from chat.py extended with new providers.

Fixed environment isolation bug: _current.json version pointer in the shared Modal Volume was not namespaced per-environment. Now uses _current_{env}.json so dev/jh/main track active versions independently while sharing the same model weights.

New files:

  • ml/comparison.html — side-by-side streaming comparison UI
  • stream_openai(), stream_claude(), stream_model_slot() in gateway/providers.py

Changed:

  • gateway/chat.py — routes Claude, OpenAI, model slots; adds timing metadata
  • training/model_registry.py — env-aware _current_{env}.json with legacy fallback
  • ml_endpoint.py — /comparison route
  • ML_PIPELINE_SPEC.md — updated env isolation docs

b9b7b53 — Add project documentation

Created docs/ folder with architecture overview, service catalog, and changelog infrastructure covering W14-W15.

9bc71f9 — Remove SSE_ONLY encryption type (jh branch)

Removed SSE_ONLY encryption type from dev/core/data.py. Video recordings now stored as PLAINTEXT until a proper per-account video encryption strategy is designed. This avoids shipping a half-baked encryption approach that would need to be reworked later.

Changed:

  • core/data.py — removed SSE_ONLY from encryption type enum and related handling
