Can the report worker read customer records?
Subject: Halyard Example Co. (fictional). This page shows the shape of a brief. It is not a product output, and its conclusions are about fictional systems.
Current interpretation
Reviewed interpretation The documented restriction plausibly holds from 2026-07-08 onward, but this is unconfirmed: there is no captured revision 18 policy or deployment evidence.
Review state: Open: Reviewer A (fictional), 2026-07-20
Claims and evidence
The report worker runs as svc-report-worker.
Ambiguous identity · candidate only, not merged
Supporting evidence
-
The report worker runs as svc-report-worker. It reads only from the billing-exports queue and has no access to the customer-records store.
-
{ "Sid": "ReadBillingExports", "Effect": "Allow", "Action": "queue:Read", "Resource": "queue/billing-exports" }
The policy names the same identity, but does not bind it to a deployed worker.
What remains uncertain
The shared name suggests a match, but no deployment binding establishes that the documented worker and policy identity are the same deployed actor. Keep this identity unresolved.
The report worker reads only from billing-exports and has no access to customer-records.
Contradicted for the 2026-04-15 capture
Supporting evidence
-
The report worker runs as svc-report-worker. It reads only from the billing-exports queue and has no access to the customer-records store.
Conflicting or superseding evidence
-
{ "Sid": "TemporaryBackfill", "Effect": "Allow", "Action": "store:Read", "Resource": "store/customer-records/*", "Condition": { "DateLessThan": { "now": "2026-06-30T00:00:00Z" } } }
Policy revision 17 still allowed reads on customer-records until 2026-06-30, after the architecture document was published.
What remains uncertain
The document states an intended boundary. The captured policy shows an exception that the document does not mention.
Policy revision 17 lets svc-report-worker read customer-records/* until 2026-06-30.
Extracted from configuration
Supporting evidence
-
{ "Sid": "TemporaryBackfill", "Effect": "Allow", "Action": "store:Read", "Resource": "store/customer-records/*", "Condition": { "DateLessThan": { "now": "2026-06-30T00:00:00Z" } } }
Conflicting or superseding evidence
-
The report worker runs as svc-report-worker. It reads only from the billing-exports queue and has no access to the customer-records store.
The architecture overview says there is no access to customer-records.
What remains uncertain
The policy shows what was permitted, not whether the permission was used or whether revision 17 was the deployed revision.
CHG-0142 removed the TemporaryBackfill statement; revision 18 contains only ReadBillingExports.
Stated, not independently observed
Supporting evidence
-
Removed the TemporaryBackfill statement from the svc-report-worker policy after the backfill completed. Policy revision 18 contains only ReadBillingExports.
What remains uncertain
Policy revision 18 is not in this corpus, so the removal is reported by the change record but not observed in configuration.
The documented restriction plausibly holds from 2026-07-08 onward, but this is unconfirmed: there is no captured revision 18 policy or deployment evidence.
Open: Reviewer A (fictional), 2026-07-20
Supporting evidence
-
{ "Sid": "TemporaryBackfill", "Effect": "Allow", "Action": "store:Read", "Resource": "store/customer-records/*", "Condition": { "DateLessThan": { "now": "2026-06-30T00:00:00Z" } } }
The exception existed at the 2026-04-15 capture.
-
Removed the TemporaryBackfill statement from the svc-report-worker policy after the backfill completed. Policy revision 18 contains only ReadBillingExports.
The change record says the exception was removed.
What remains uncertain
To close this, request policy revision 18 and evidence of which revision was deployed after 2026-07-08.
