The connect directive parsed its params JSON outside any rescue, so malformed params killed the interface or router handler thread and no ack was sent. Both implementations now log the error, ack it, and leave the interface as is. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Catch invalid JSON byte encoding in both connect handlers. json.loads can raise UnicodeDecodeError for invalidly encoded byte-valued params. Neither catch intercepts it, so the affected handler cannot acknowledge the error or process subsequent directives. The Ruby handlers rescue parsing errors on these paths. (docs.python.org)

Summary
connectdirective parsed itsparamsJSON outside any rescue in both the interface command handler and the router telemetry handler. Malformed params raised out of the handler, which killed the thread, and no ack was sent.Invalid connect params: ..., and ack the error message. The interface or router is left unchanged andattemptingisn't called. Valid params work as before.Fixes the IF-CON-005 deviation in
architecture/specs/interface-microservice.yaml. The same parse in the router handler had the same bug, so it's fixed here too. This complements #4002, which coveredcmd_params,interface_cmdandprotocol_cmd.Test plan
