 ### Fixes
 
 - Google Chat: preserve reply text when a typing indicator message is deleted or can no longer be updated, so media captions and first text chunks are resent instead of silently disappearing. (#71498) Thanks @colin-lgtm.
+- Cron: tolerate malformed legacy job rows in startup, main-session system-event payloads, and human-readable `cron list` output so missing `state`, `payload.text`, or display fields no longer crash the scheduler or CLI. Fixes #66016, #65916, #64137, #57872, #59968, #63813, #52804, and #43163.
 - Heartbeat: clamp oversized scheduler delays through the shared safe timer helper, preventing `every` values over Node's timeout cap from becoming a 1 ms crash loop. Fixes #71414. (#71478) Thanks @hclsys.
 - Control UI/chat: collapse assistant token/model context details behind an explicit Context disclosure and show full dates in message footers, making historical transcript timing clear without noisy default metadata. (#71337) Thanks @BunsDev.
 - OpenAI/Codex OAuth: explain `unsupported_country_region_territory` token-exchange failures with a proxy/region hint instead of surfacing a generic OAuth error. Fixes #51175.
