tui_gateway/contracts/ is the single source of truth for the JSON-RPC wire:
Params/Result/Payload bases, a registry of METHODS / SERVER_REQUESTS /
EVENTS, runtime validation (unknown/mistyped params answer 4000 with the
field path; a result or payload that violates its model raises under the
test suite and logs once in production), and the server-request contracts
+ shared value shapes as the authoring template. scripts/gen_gateway_contracts.py
renders the tables through a small JSON-Schema-subset walker into
apps/shared/src/gateway-contract.generated.ts and
gateway-contract.openrpc.json (unsupported constructs raise at generation).
Method contracts for the 213 remaining handlers follow in the next commits.
Docstring/comment compaction plus small structural dedupe across the
tui_gateway peripheral modules. Originally landed as an outage-recovery
snapshot; reviewed and verified afterwards (import smokes, cluster tests).
