Validated on the combined batch board + this branch: antigravity-dynamic-session-id + proxy-fetch-dns-retry green; file-size gate green with the proxyFetch 1244 frozen entry (dated annotation for the +5 retry-classification lines, owner-authorized). Static per-account sessionId unpinning ends the concurrent-turn 429s and EmptyStreamError drops on the Hermes→Antigravity path; EAI_AGAIN/ENOTFOUND/ETIMEDOUT now classified retryable. Conflict with the tip was only stale provider-count docs. Resolves the remaining #10443 root causes. Thank you @rqzbeh!
