Filed unassigned by the #13571 dev while measuring that card's PM mechanism assumption 1 ("check who actually calls this compiler"). Recording only — severity and routing are triage's. This finding is decision-material for #13571 but does not block it and is not resolved by it.

What was measured, on eb64351

  • ObjectQLStrategy merges StrategyContext.getReadScope output into the FilterCondition it hands the engine (packages/services/service-analytics/src/strategies/objectql-strategy.ts, the ctx.getReadScope(objectName) merge near the userFilter return, ~:601-602). On that execution path the scope never reaches compileScopedFilterToSql — read-scope-sql compiles the scope only on the NativeSQL path (applyReadScope) and for the /analytics/sql echo (generateSql).
  • driver-sql lowers $nin: [] via whereNotIn(field, []) wrapped null-safe (packages/drivers/driver-sql/src/sql-driver.ts, the $nin case near :13314) — constant TRUE. Live in-repo pin of the semantics: packages/services/service-analytics/src/__tests__/filter-normalizer-not-null-safe.test.ts:534 (stage: { $nin: [] } admits ALL rows on a real backend).
  • Consequence: a non-RLS getReadScope provider (StrategyContext.getReadScope is a spec contract — packages/spec/src/contracts/analytics-service.ts ~:385 carries a hand-written example) handing { f: { $nin: [] } } or { $not: { f: { $in: [] } } } gets the whole table on any query the ObjectQL strategy serves, regardless of what read-scope-sql's emptied-membership folds are polarity-dependent at the lowering site itself: $in: [] folds to 1 = 0 one arm from $not, and $nin: [] folds to 1 = 1 (constant TRUE) #13571 ships in read-scope-sql — a compile refusal there can only ever guard the NativeSQL path and the echo.

What keeps it from biting today

Identical protection profile to #13571's: in-repo the only scope producer is the RLS compiler, and since PR #13570 its polarity-aware guard drops both shapes before they are emitted; the CEL lowering never emits $nin at all. The vacancy is the same as #13571's, one strategy over: no mechanical guard stands between a spec-contract producer and the engine lowering.

            Filed unassigned by the #13571 dev while measuring that card's PM mechanism assumption 1 ("check who actually calls this compiler"). Recording only — severity and routing are triage's. This finding is decision-material for #13571 but does not block it and is not resolved by it.
            What was measured, on eb64351
            • ObjectQLStrategy merges StrategyContext.getReadScope output into the FilterCondition it hands the engine (packages/services/service-analytics/src/strategies/objectql-strategy.ts, the ctx.getReadScope(objectName) merge near the userFilter return, ~:601-602). On that execution path the scope never reaches compileScopedFilterToSql — read-scope-sql compiles the scope only on the NativeSQL path (applyReadScope) and for the /analytics/sql echo (generateSql).
            • driver-sql lowers $nin: [] via whereNotIn(field, []) wrapped null-safe (packages/drivers/driver-sql/src/sql-driver.ts, the $nin case near :13314) — constant TRUE. Live in-repo pin of the semantics: packages/services/service-analytics/src/__tests__/filter-normalizer-not-null-safe.test.ts:534 (stage: { $nin: [] } admits ALL rows on a real backend).
            • Consequence: a non-RLS getReadScope provider (StrategyContext.getReadScope is a spec contract — packages/spec/src/contracts/analytics-service.ts ~:385 carries a hand-written example) handing { f: { $nin: [] } } or { $not: { f: { $in: [] } } } gets the whole table on any query the ObjectQL strategy serves, regardless of what read-scope-sql's emptied-membership folds are polarity-dependent at the lowering site itself: $in: [] folds to 1 = 0 one arm from $not, and $nin: [] folds to 1 = 1 (constant TRUE) #13571 ships in read-scope-sql — a compile refusal there can only ever guard the NativeSQL path and the echo.
            What keeps it from biting today
            Identical protection profile to #13571's: in-repo the only scope producer is the RLS compiler, and since PR #13570 its polarity-aware guard drops both shapes before they are emitted; the CEL lowering never emits $nin at all. The vacancy is the same as #13571's, one strategy over: no mechanical guard stands between a spec-contract producer and the engine lowering.
