Claude Code: Investigate the data persistence layer to ensure Cain's memories are saf

Claude Code: Fix the two critical bugs identified in the audit:

Fix OpenAI provider config: Add models array and skip placeholder API keys

Claude Code: Cain is showing RUNTIME_ERROR status. I need you to:

Infrastructure migration: Align Cain with HuggingClaw architecture

Upload scripts/sync_hf.py with huggingface_hub

fix: delete devices dir to force fresh auto-pair, skip error replies

fix: patch paired device scopes for OpenClaw 2026.2.19+ compatibility

fix: clean up invalid auth.defaultScope from persisted config

fix: revert invalid OpenClaw config keys causing RUNTIME_ERROR

fix: add operator scope to gateway auth and A2A security config

fix: reduce verbose logging to prevent HF Spaces log viewer crashes

Upload scripts/sync_hf.py with huggingface_hub

Upload scripts/sync_hf.py with huggingface_hub

feat: add A2A gateway support (activated by A2A_PEERS env var)

Revert "feat: add pixel animation homepage with Express proxy layer"

feat: add pixel animation homepage with Express proxy layer

fix: switch Zhipu provider to Anthropic-compatible endpoint

fix: update Zhipu AI model IDs to current API lineup

fix: add required models array to zhipu provider config

fix: rebuild providers from scratch on each startup

feat: add Zhipu AI (z.ai) as a native LLM provider

fix: remove tao-shen/HuggingClaw-data refs to prevent unwanted linked spaces

test: revert dataset derivation to observe linked spaces behavior

fix: restore OPENCLAW_DATASET_REPO priority over SPACE_ID derivation

fix: always derive dataset from SPACE_ID, ignore OPENCLAW_DATASET_REPO on HF

fix: revert to token auth with default "huggingclaw"

feat: default to no-auth mode — Control UI connects instantly

fix: auto-derive dataset name from SPACE_ID, not HF_TOKEN username

feat: add GATEWAY_TOKEN env var (default: huggingclaw)

fix: restore dangerouslyDisableDeviceAuth for HF Spaces

config: set hardcoded gateway token "huggingclaw" as default

remove: drop gateway password/token auth entirely — device auth only

security: enforce device auth — only paired browsers can access Control UI

feat: switch auth from password to token mode (persists in browser)

fix: always force dmPolicy=open + allowFrom=["*"] on every startup

fix: add allowFrom=["*"] required by dmPolicy=open

fix: set Telegram dmPolicy=open and configWrites=true for HF Spaces

feat: telegram-proxy.cjs intercepts fetch() to bypass HF DNS block

fix: validate Telegram bot token format before probe (skip junk tokens)

fix: revert auth to password mode, add Telegram API auto-probe, background DNS

feat: switch auth from password to token for browser persistence

feat: derive dataset name from Space repo name to avoid conflicts

fix: remove leftover _ensure_telegram_credentials() call causing RUNTIME_ERROR

fix: patch config when dataset exists but is empty

feat: auto-derive dataset repo name from HF_TOKEN when AUTO_CREATE_DATASET=true

security: change AUTO_CREATE_DATASET default to false

docs: add detailed env var table with examples, change sync interval to 60s

chore: replace gpt-4o-mini with gpt-5-nano everywhere

chore: default model → openai/gpt-oss-20b:free (OpenAI open-source)
