Parity pass on the other three language templates. Same guarantees as go/: survive server restart, client restart, half-open TCP, and long outages; rejoin and drain prime-side backlog on reconnect, without the user writing any of this in process.*. python/main.py: - grpc.keepalive_time_ms=10000, keepalive_timeout_ms=3000, keepalive_permit_without_calls=1 on the channel. Half-open TCP is detected within ~13s instead of the OS default ~2h. - Exponential backoff with jitter; max_backoff_seconds config ceiling (default 120). Attempts counter resets after a session runs healthy for 60s so transient restarts don't escalate the delay. - chain_id added as a required config field and sent as the x-chain-id gRPC metadata header (prime rejects streams without it). typescript/src/main.ts: - Same keepalive options on the @grpc/grpc-js client. - Same exponential backoff + jitter logic. - chain_id added to Config + metadata. bash/: - Config + README updated. The bash template uses Python's main.py as its runtime, so the behavioural changes above flow through without a separate main per language. Docs: each README gains a "Durability guarantees" section so contract authors see the invariants without reading the runtime code.
