fix(cron): suppress fallback summary after attempted announce delivery

CHANGELOG.md

@@ -39,6 +39,7 @@ Docs: https://docs.openclaw.ai
 - Security/Browser temp paths: harden trace/download output-path handling against symlink-root and symlink-parent escapes with realpath-based write-path checks plus secure fallback tmp-dir validation that fails closed on unsafe fallback links. This ships in the next npm release (`2026.2.25`). Thanks @tdjackey for reporting.
 - Gateway/Message media roots: thread `agentId` through gateway `send` RPC and prefer explicit `agentId` over session/default resolution so non-default agent workspace media sends no longer fail with `LocalMediaAccessError`; added regression coverage for agent precedence and blank-agent fallback. (#23249) Thanks @Sid-Qin.
 - Cron/Message multi-account routing: honor explicit `delivery.accountId` for isolated cron delivery resolution, and when `message.send` omits `accountId`, fall back to the sending agent's bound channel account instead of defaulting to the global account. (#27015, #26975) Thanks @lbo728 and @stakeswky.
+- Cron/Announce duplicate guard: track attempted announce/direct delivery separately from confirmed `delivered`, and suppress fallback main-session cron summaries when delivery was already attempted to avoid duplicate end-user sends in uncertain-ack paths. (#27018)
 - Cron/Model overrides: when isolated `payload.model` is no longer allowlisted, fall back to default model selection instead of failing the job, while still returning explicit errors for invalid model strings. (#26717) Thanks @Youyou972.
 - Security/Gateway auth: require pairing for operator device-identity sessions authenticated with shared token auth so unpaired devices cannot self-assign operator scopes. Thanks @tdjackey for reporting.
 - Security/Gateway WebSocket auth: enforce origin checks for direct browser WebSocket clients beyond Control UI/Webchat, apply password-auth failure throttling to browser-origin loopback attempts (including localhost), and block silent auto-pairing for non-Control-UI browser clients to prevent cross-origin brute-force and session takeover chains. This ships in the next npm release (`2026.2.25`). Thanks @luz-oasis for reporting.
