v0.19.8 — provider-gateway hardening
Questa è la nota di release così com'è stata pubblicata, non una sua riscrittura. Le note di release sono pubblicate nella lingua in cui sono state scritte.
The 16th adversarial review swept the provider gateway (LLM failover / key rotation / retry / cost / cache) and found 4 real bugs, 1 HIGH. All fixed with regression tests.
Fixed
- 🎯 The completion cache no longer defeats consensus checks (HIGH). It served
temperature>0samples, sokidentical sampled requests returned byte-identical content — collapsing cascade agreement, the fusion router's agreement gate, and self-consistency into fake unanimity (false confidence). The cache now serves/stores only deterministic (temperature==0) requests. - An empty-content result is no longer cached — one malformed response would otherwise serve
""forever at $0 for that key. acomplete()now honors the credential pool — a pool-only config (CHIMERA_OPENROUTER_KEYSwith no single*_API_KEY) previously AUTH-failed.- The lazy key-rotator creation is lock-guarded against the fusion panel's threads.
The failover taxonomy, key rotation/cooldown, cache-hit $0 accounting, cost-on-actual-model-after-failover, atomic cache writes, streaming reassembly and budget clamp all reviewed clean.
Gate: 1468 passed / 4 skipped, mypy + ruff green.
