Add SSE keepalive pings every 15s to prevent proxy timeout disconnects

Fix: use custom X-LLM headers instead of Authorization (HF proxy intercepts it)

Two-model approach: 7B for setup calls, 72B for evaluation

Add 45s timeout + 2 retries on LLM client to prevent Space restarts

Use /data/nemotron for persistent storage on HF Spaces

Fix port binding: start.sh kills zombie, add app logging

Fix port binding: simplify startup, remove timeout on segments, clean SIGTERM

Fix port binding crash: kill zombie process and enable SO_REUSEADDR

Remove session restore — was only for debugging

Fix startup: use lifespan instead of deprecated on_event

Set rate limit to 2 runs per hour

Rate limit by pipeline runs (10/hr), not individual LLM calls

Security hardening: rate limiting, no creds in URLs, path traversal fix

Pass LLM credentials per-request, never store server-side

Add HuggingFace Spaces deployment support

Fix XSS, VJP contract, binding, session security, name collisions, and error handling

Fix production issues: session overwrite, error handling, memory leaks

Remove personal/dating examples from all placeholders and prompts

Fix 422 on counterfactual stream — remove **kwargs from endpoint

Move counterfactual params from GET query to POST+ticket to avoid log leakage

Fix missing compute_goal_weights import

Make entity, goal, and audience first-class inputs

Extract demographic filters from audience context for Nemotron cohorts

Restore saved sessions from disk on server startup

Auto-generate changes from concerns, one-click directions flow

Add goal-weighted gradient (VJP) — optimize toward objectives, not universal appeal

Fix panel size overflow — hard cap Nemotron cohort to requested total

Lazy-load HuggingFace datasets to fix slow startup

Use Nemotron personas when available, add dataset setup UI

Remove dating/relationship references from all files

Auto-suggest context-aware segments from entity via LLM

Add bias audit to web interface, make web the primary entry point, switch to MIT license

Add web interface for SGO pipeline
