   ⛔ Not a claim.

   • Read fresh. A preset dateRange on a date field counts the wrong calendar days east of UTC (Shanghai this_quarter counts Jun 30 and drops Sep 30). The zone's midnight instants are compared against bare dates. These are wrong report numbers for every non-UTC tenant, so p2, as its source analytics: a dataset query with a timeDimensions window returns no drill bounds for it, so a report drill-down lists records outside the picked period #27074.
   • ⛔ One rule: a date field compares calendar days in the reference zone (ADR-0053's calendar-day semantics), and a datetime compares instants. The executor's existing whole-day rule is used, not a new resolver.

   Claim: PM loop round 1 · card thread
   Session: session_01Utp6CXc5hequf76uJfzrdK (the seat); the card thread is session_01Utp6Caqg6E9ggEvoUcYsbq
   Account: os-bill (the seat's linked user; the card's assignee)
   Branch: claude/project-thread-s7v4ey (the card thread's harness-pinned branch; it names no issue, so this claim is the identity record)
   Worktree: objectstack-issue-27172 in the card thread's own container
   Domain: domain:server
   Seat: domain:server#3
   File surface: packages/services/service-analytics/src/** (the preset window lowering shared by count and drill), the whole-day rule's existing home if the fix belongs there (packages/core/src/utils/temporal-* read first; an edit there is declared in the report), tests, a patch changeset per touched package. Stop on breach.
   Container & model: M, mode:thread, model: TIER_DEFAULT (dispatch-gates --tier: no path-derived mandate), effort: high
   Clause-②: no — a wrong-answer fix; no accept set or public surface changes.
   Metadata-protocol: none
   Responsibility: the analytics preset-window lowering (service-analytics) produces the wrong window for date fields east of UTC | the executor's existing whole-day rule (triage 6465987107) | every non-UTC tenant's dataset queries and drills through the public analytics door, today
   Thread-read: 6465987107
   Premise: holds (read at origin/main 9ff8154c: the card's source PR #27169 is merged; no open PR touches service-analytics or the temporal storage helpers); the dev reproduces the Shanghai this_quarter case red first
   Serial constraints cleared: none — no open PR or in-flight claim on the declared surface at this read

   State: pm:queue → pm:dispatched, assigned to os-bill, in the label act before this comment.

The executor's existing whole-day rule is inclusiveCalendarDayWindow in packages/services/service-analytics/src/dataset-executor.ts (the projection compareTo already shifts); new dateRangeWindowBounds beside it spells a resolved preset on a date column as that inclusive day pair and leaves datetime instants and explicit windows unchanged. It is the one spelling NativeSQLStrategy, ObjectQLStrategy (execute and echo), drillWindowBounds and the draft preview call, so drill and count stay on one lowering; declaredDateColumn (filter-normalizer.ts) asks the same declaredFieldType hook as declaredDatetimeLowering. Bounded in-place fix declared in the PR: the draft preview face (preview-evaluator.ts, inside the claim surface) had the same defect, measured red. No edit under packages/core.",
