test(db): add loadSubset and pagination oracles - #1750

📝 WalkthroughWalkthroughThe PR adds test guidance and broad coverage for ChangesLoad subset validation
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to This PR adds extensive database oracle coverage without changing runtime behavior, but the current test code still has bounded reliability and regression-detection risks: asynchronous failures may surface as intermittent CI errors, and one known-failure path may accept more refetching than intended.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Await the preload promises before the pending-load assertion.
first and second hold rejectable promises. If expect(pending).toHaveLength(2) throws at line 865, control jumps to finally, which calls source.cleanup(). A preload that then rejects produces an unhandled rejection, and the noise can fail an unrelated test. Attach a handler as soon as the promises are created, or settle them in finally.

🧩 Analysis chain
🌐 Web query:
Does Vitest name its process unhandledRejection listener vitestUnhandledRejectionHandler?
💡 Result:
No, Vitest does not name its process unhandledRejection listener vitestUnhandledRejectionHandler. In the Vitest source code, specifically within the error catcher implementation, the listener function assigned to the unhandledRejection event is simply named unhandledRejection [1][2]. It is defined as a local function within the listenForErrors scope and is not assigned the name vitestUnhandledRejectionHandler [1][2]. While some third-party libraries or codebases may attempt to identify and manipulate Vitest's listeners by checking the name property of functions attached to the process object [3], this approach is not supported by Vitest's internal naming conventions [1][2]. These third-party attempts to find a function named vitestUnhandledRejectionHandler are based on an incorrect assumption about how Vitest names its internal listeners [3][1][2].

Vitest 3.2.4 errorCatcher.ts unhandledRejection listener function name
💡 Result:
In the Vitest source file packages/vitest/src/runtime/moduleRunner/errorCatcher.ts, the listener function used for unhandledRejection events is named unhandledRejection [1][2]. This function is defined as a constant inside the listenForErrors function and is passed to process.on (or processOn in more recent versions) to catch and handle unhandled promise rejections during test execution [1][2]. It typically delegates to a helper function called catchError [1]. Specifically, the implementation looks like this: const unhandledRejection = (e: Error) => catchError(e, 'Unhandled Rejection', 'unhandledRejection') [1][2].

Remove the Vitest listener by reference, not by function name. Vitest registers its unhandledRejection listener as unhandledRejection, not vitestUnhandledRejectionHandler. Therefore, the deliberate transport failed rejection can reach Vitest's handler.

This adds independent
loadSubsetand pagination oracles across core DB, query-db, Electric, and TrailBase. It changes no runtime behavior: known defects are pinned as exact expected failures so later fixes can turn them green without weakening coverage.Approach
Promise.prototype.TANSTACK_DB_ORACLE_SEEDreplays a random failure, whileTANSTACK_DB_ORACLE_RUNS_MULTIPLIERscales campaign depth.Key invariants
limit: 0, null placement, mixed directions, and the public-key tie-breaker.Report coverage
The tests pin current failures around ordered-window refill and multi-column boundaries, semantic coverage and owner release, canonical predicate identity, persistence publication, query-db error state, and TrailBase startup settlement.
The review pass added exact coverage for:
INand zero-limit windows issuing unnecessary transport work;Green controls cover zero-limit rendering and restoration, descending and mixed multi-column order, complete-tuple key ties, live mutation order on both sides of a pending response, cancellation/remount, predicate forwarding, computed-sort non-pushdown, and joined-key deduplication.
Non-goals
hasMorecontract remains deferred becauseloadSubsetdoes not expose whether an under-filled transport result is complete.getNextPageParamcontract remain design decisions for follow-up work.Trade-offs
The suite uses small independent models rather than one universal simulator. This keeps each oracle auditable and shrinkable. Generated properties stop at the first explicit known failure; deterministic examples preserve its exact boundary. Fixed seeds keep CI reproducible, while the second random run and replay environment variable retain breadth.
Verification
The final 100x campaign passed 60 focused tests and 29,600 generated cases:
Committed fixed seeds are
1657,1658, and1659. Captured random seeds include920236938,2103173287,1023638446,-365808399,393974185,1285855849, and the minimized offset-shift seed-603909333.Focused query-db, TrailBase, and Electric lifecycle tests also pass with typechecking, as do ESLint, Prettier, and
