Thirty-minute Daylab cadence explains recurring Telegram updates

2026.08.10 at 13:40:04 America/Los_Angeles Cause identified; notification behavior unchanged Machine-readable JSON

Executive summary

Recurring Telegram updates were traced to the standalone Daylab process restored during Hiro's morning restart.

Daylab is configured to run every 30 minutes. Its self-improvement finalization path unconditionally schedules a Telegram completion briefing after every cycle when Hiro's Telegram notification marker is enabled.

The Telegram marker was re-enabled when the bot was restarted, so the high-cadence evidence collector and the general notification channel became coupled.

Eleven Daylab cycles completed between 08:32 and 13:31, closely matching the observed recurring-update cadence.

All Windows Hiro scheduled tasks remain disabled, the durable sandbox-notification outbox is empty, and the Telegram bot's polling loop does not itself create unsolicited updates.

No settings or processes were changed during diagnosis.

Work completed

Runtime-source tracing

Complete

Enumerated the active Hiro API, Daylab, and Telegram bot processes and inspected their current logs.
Confirmed Daylab completed at approximately 30-minute intervals throughout the day.
Verified the Telegram-notifications marker has remained enabled since the morning restart.
Verified all discovered Windows Hiro tasks, including Stage 6, remain disabled.

Notification-code tracing

Complete

Daylab calls the self-improvement v2 workflow on every cycle.
The workflow's finalization function always schedules a SELF-IMPROVEMENT V2 COMPLETE Telegram briefing; it has no cadence-specific suppression or separate Daylab notification preference.
The shared Telegram sender permits delivery whenever the lifecycle marker is present and sends to the first configured allowed user.
Recent Daylab logs also show some briefings failing Telegram Markdown parsing, meaning the implementation attempts every briefing even when delivery is inconsistent.

Alternative-source elimination

Complete

The durable sandbox-review notification outbox contains no queued or sent records.
A read-only evaluation of every current health-monitor check returned no active issue, so the health monitor is not presently generating alerts.
The Telegram bot process is polling for inbound messages; polling does not explain periodic unsolicited sends.
The nightly internal scheduler is configured for a later start and does not match the observed daytime 30-minute pattern.

Decisions and reasoning

Treat Daylab's unconditional completion briefing as the primary cause because its observed cycle timestamps match the update cadence and its code directly schedules Telegram delivery.
Distinguish Windows Task Scheduler state from Hiro's in-process and standalone loops; disabling Windows tasks does not stop Daylab or the internal health scheduler.
Do not change notification behavior during a diagnosis-only request.
Keep Stage 6 controls unchanged; the recurring Telegram updates are independent of Stage 6 promotion state.

Validation and evidence

Check	Status	Result
Daylab cadence	confirmed	Eleven successful cycle-completion timestamps were observed between 08:32 and 13:31 at approximately 30-minute spacing.
Telegram authorization marker	confirmed	The shared Telegram-notifications marker is present and has been active since the morning restart.
Windows scheduled tasks	excluded	All three discovered Hiro tasks remain disabled.
Sandbox notification outbox	excluded	The outbox query returned no records.
Current health-monitor issues	excluded	Read-only execution of the component checks returned no LLM, lab, error-rate, fix-effectiveness, or briefing issue.

Current state

Hiro, Qwen, Daylab, and the Telegram bot remain running.
Daylab remains configured for a 30-minute interval and continues to attempt a Telegram completion briefing after each cycle.
Telegram notifications remain globally enabled.
Windows scheduled tasks and Stage 6 promotion remain disabled.
No notification setting or runtime process was changed by this diagnostic session.

Next steps

Ask the user whether to stop only Daylab summaries, reduce their cadence, or disable all proactive Telegram notifications while keeping the interactive bot available.
If requested, separate Daylab briefing authorization from the global Telegram marker and cover the behavior with focused tests.
Preserve promotion and critical health notifications independently if the user wants only routine summaries suppressed.
