The current worker reads inventory from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a fraud event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Turn this material into a concise maintainer-facing note that states the observed contract, operational warning signs, and a reproducible example; do not invent guarantees.","purpose":"writing","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

{"prompt":"Support noticed the checkout worker (B01L079)\nCaptured ticket excerpt:\nTitle: Make checkout reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads inventory from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a fraud event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Make the smallest safe correction supported by this evidence, add one focused regression test, and avoid unrelated cleanup or dependency changes.","purpose":"quickFix","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

{"prompt":"Security questioned the inventory guard (B01L134)\nCaptured ticket excerpt:\nTitle: Make checkout reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads inventory from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a fraud event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Turn this material into a concise maintainer-facing note that states the observed contract, operational warning signs, and a reproducible example; do not invent guarantees.","purpose":"writing","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

The current worker reads inventory from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a fraud event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Trace the conflicting attempts to a specific cause, test the hypothesis, and show how a deterministic regression case reproduces the failure before proposing a patch.","purpose":"debugging","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

The current worker reads routing from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a localization event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Assess the pasted artifact for correctness, security, compatibility, and test gaps.

{"prompt":"This sessions module (B04L014)\nCaptured ticket excerpt:\nTitle: Make identity reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads sessions from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a permissions event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Reshape the responsible code so duplicated decisions have one owner while behavior, ordering, metrics, and public errors stay stable; add characterization coverage first.","purpose":"refactor","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Complete the affected interface, including loading, empty, error, retry, focus, and narrow-screen behavior, using the existing hooks and design tokens.","purpose":"frontendImpl","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

The current worker reads transcoding from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a storage event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Turn this material into a concise maintainer-facing note that states the observed contract, operational warning signs, and a reproducible example; do not invent guarantees.","purpose":"writing","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

The current worker reads transcoding from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a storage event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Assess the pasted artifact for correctness, security, compatibility, and test gaps.

The current worker reads invoicing from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a tax event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Turn this material into a concise maintainer-facing note that states the observed contract, operational warning signs, and a reproducible example; do not invent guarantees.","purpose":"writing","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

The current worker reads invoicing from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a tax event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier?

{"prompt":"Support noticed the indexing worker (B07L054)\nCaptured ticket excerpt:\nTitle: Make search reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads ranking from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a indexing event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: erstelle eine knappe Maintainer-Doku mit Vertrag, Fehlerfällen und Beispiel.

Check both an explicitly supplied value and the absent-value case, then report the exact files touched and why the change cannot affect callers that already use the new field. After completing that main task, also handle this separate need: Over time this module accumulated several paths that normalize the same input, choose a policy, and emit nearly identical results. Rework it so those decisions live in one obvious place while public types, error messages, and observable ordering remain stable. Prefer small named helpers over a new framework, preserve metrics and cancellation behavior, and keep the diff reviewable. Add characterization coverage where behavior is implicit, remove dead branches only when the tests prove they are unreachable, and leave a short note explaining the resulting ownership boundaries.

{"prompt":"On-call traced the ranking failure (B07L149)\nCaptured ticket excerpt:\nTitle: Make search reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads ranking from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a indexing event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Complete the affected interface, including loading, empty, error, retry, focus, and narrow-screen behavior, using the existing hooks and design tokens.","purpose":"frontendImpl","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

The current worker reads presence from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a notifications event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Turn this material into a concise maintainer-facing note that states the observed contract, operational warning signs, and a reproducible example; do not invent guarantees.","purpose":"writing","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

The current worker reads presence from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a notifications event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Turn this material into a concise maintainer-facing note that states the observed contract, operational warning signs, and a reproducible example; do not invent guarantees.","purpose":"writing","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

{"prompt":"Security questioned the presence guard (B08L134)\nCaptured ticket excerpt:\nTitle: Make messaging reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads presence from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a notifications event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Complete the server behavior implied here with tenant authorization, validation, idempotency, structured errors, metrics, and integration coverage for retries and partial failure.","purpose":"backendImpl","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

The current worker reads presence from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a notifications event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Turn this material into a concise maintainer-facing note that states the observed contract, operational warning signs, and a reproducible example; do not invent guarantees.","purpose":"writing","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

{"prompt":"Security questioned the offline-sync guard (B09L009)\nCaptured ticket excerpt:\nTitle: Make maps reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads geocoding from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a offline-sync event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Turn this material into a concise maintainer-facing note that states the observed contract, operational warning signs, and a reproducible example; do not invent guarantees.","purpose":"writing","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

{"prompt":"On-call traced the geocoding failure (B09L149)\nCaptured ticket excerpt:\nTitle: Make maps reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads geocoding from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a offline-sync event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: erstelle eine knappe Maintainer-Doku mit Vertrag, Fehlerfällen und Beispiel.

The current worker reads experiments from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a consent event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Produce a staged execution plan with owners, dependencies, observability, compatibility checks, rollout gates, and an explicit rollback path; make no code changes yet.","purpose":"planning","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

The current worker reads experiments from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a consent event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Make the smallest safe correction supported by this evidence, add one focused regression test, and avoid unrelated cleanup or dependency changes.","purpose":"quickFix","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

{"prompt":"Security questioned the timezones guard (B11L009)\nCaptured ticket excerpt:\nTitle: Make scheduling reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads calendars from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a timezones event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier?

{"prompt":"Security questioned the timezones guard (B11L159)\nCaptured ticket excerpt:\nTitle: Make scheduling reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads calendars from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a timezones event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Turn this material into a concise maintainer-facing note that states the observed contract, operational warning signs, and a reproducible example; do not invent guarantees.","purpose":"writing","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

{"prompt":"Somehow the firmware path (B12L044)\nCaptured ticket excerpt:\nTitle: Make devices reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads firmware from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a provisioning event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Reshape the responsible code so duplicated decisions have one owner while behavior, ordering, metrics, and public errors stay stable; add characterization coverage first.","purpose":"refactor","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Reshape the responsible code so duplicated decisions have one owner while behavior, ordering, metrics, and public errors stay stable; add characterization coverage first.","purpose":"refactor","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Complete the server behavior implied here with tenant authorization, validation, idempotency, structured errors, metrics, and integration coverage for retries and partial failure.","purpose":"backendImpl","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

{"prompt":"On-call traced the rosters failure (B13L099)\nCaptured ticket excerpt:\nTitle: Make education reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads grading from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a rosters event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: 契約、失敗例、実例を含む短い保守向けドキュメントを残して. 技術的な前提: Turn this material into a concise maintainer-facing note that states the observed contract, operational warning signs, and a reproducible example; do not invent guarantees.","purpose":"writing","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"ja"}

The current worker reads sync from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a privacy event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Trace the conflicting attempts to a specific cause, test the hypothesis, and show how a deterministic regression case reproduces the failure before proposing a patch.","purpose":"debugging","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

{"prompt":"This sync module (B14L089)\nCaptured ticket excerpt:\nTitle: Make health-data reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads sync from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a privacy event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Assess the pasted artifact for correctness, security, compatibility, and test gaps.

The current worker reads sync from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a privacy event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: avalie a mudança e aponte riscos concretos sem editar o código.

The current worker reads sync from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a privacy event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Complete the affected interface, including loading, empty, error, retry, focus, and narrow-screen behavior, using the existing hooks and design tokens.","purpose":"frontendImpl","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

The current worker reads sync from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a privacy event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Assess the pasted artifact for correctness, security, compatibility, and test gaps.

Point to exact files or branches for every concern, separate blocking defects from optional improvements, and note any missing tests. Also check compatibility with existing callers and whether logs could expose sensitive values. Do not edit anything; return a prioritized assessment with a brief rationale. The boundary is whether to propose a safer structure or perform that restructuring now. The affected areas are deployments, feature-flags, rollbacks, and the tone should fit a migration-brief.","purpose":"review","secondary":null,"mixed":false,"difficulty":"hard","slice":"boundary","lang":"en"}

{"prompt":"Somehow the feature-flags path (B15L119)\nCaptured ticket excerpt:\nTitle: Make deployments reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads feature-flags from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a rollbacks event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: Trace the conflicting attempts to a specific cause, test the hypothesis, and show how a deterministic regression case reproduces the failure before proposing a patch.","purpose":"debugging","secondary":null,"mixed":false,"difficulty":"hard","slice":"pasted-context","lang":"en"}

{"prompt":"On-call traced the deployments failure (B15L199)\nCaptured ticket excerpt:\nTitle: Make deployments reconciliation safe during regional failover\nOwner: Platform Foundations\nTarget: 2026-Q3 maintenance window\nBackground:\nCustomers can keep editing while traffic moves between regions. The current worker reads feature-flags from a local replica, obtains a ninety-second lease, writes normalized rows, and publishes a rollbacks event. During the June exercise, replica lag exceeded the lease renewal threshold. Two workers then published different versions for the same logical operation.\nAcceptance notes:\n- Existing mobile clients must not receive a new required field.\n- A repeated operation with the same key returns the first committed result.\n- Operators can identify the winning attempt without user content in logs.\n- Rollout begins with internal tenants, then one percent, ten percent, and full traffic.\n- The old worker remains available for rollback for seven days.\nKnown constraints:\n- Table rewrites longer than thirty seconds are not approved.\n- The queue offers at-least-once delivery and may reorder messages.\n- Analytics currently treats every published event as a unique operation.\n- Security wants tenant authorization checked before idempotency lookup.\nOpen questions:\nWho owns cleanup after rollback? Can the event schema gain an optional attempt identifier? Which dashboard is authoritative when the database and queue disagree?\nComment from QA: Please include a deterministic failover test; sleeps made the earlier suite flaky.\n\nRequest: averigua por qué se repite el intento y demuéstralo con una prueba.
