pre-squash-backup-7: feat+docs: close 5 miner-onboarding gaps surfaced in code review
About SN21 AdTAO
train_example_model → hope-miner integration Trained models were never persisted; runner only accepted "baseline". scripts/train_example_model.py: --save-model PATH (joblib bundle) hope/miner/models/feature_extraction.py: shared extractor used by both training and inference (so what the model learns is what it sees in production) hope/miner/models/trained.py: TrainedXGBoostModel implementing PredictionEngine.predict(); loads the saved bundle hope/miner/runner.py: --model {baseline,trained} + --model-file Round-trip verified: train → save → load → predict on real episode HOPE_API_KEY undocumented + silent dead-end scripts/score_predictions.py: --training-data flag (offline path) Auto-fallback to bundled training_episodes.json when --release given without HOPE_API_KEY (with a clear notice; never silent) Docs (miner_quickstart §7, §9, README): canonical command now uses --training-data; HOPE_API_KEY clearly framed as operator-only, not a "miner upgrade" path hope-miner 403 → raw httpx traceback hope/miner/episode_client.py: translate 401/403/404/422 into RuntimeError with actionable next-steps (e.g., "Hotkey not registered on subnet — run btcli subnet register ...") hope/miner/runner.py: catch RuntimeError, print "❌ ", exit 1 verify_epoch.py defaults to mainnet scripts/verify_epoch.py: warn when --network/--netuid not passed explicitly ("Using default mainnet ... For testnet pass ...") docs/miner_quickstart.md Step 7 example now includes --network test --netuid 466 Hidden btcli prompts in Step 2 docs/miner_quickstart.md: 4-row table documenting each prompt (wallets dir, word count, password, retype) with the safe answer Explicit "save mnemonic to password manager / clear scrollback" guidance — same habit for testnet and mainnet, no footgun Discord: added the SN21 community channel link (discord.com/channels/799672011265015819/1489651673944297472) alongside the Bittensor faucet link. .gitignore: scoped exception so hope/miner/models/ tracks (the global "models/" ignore
