This PR began as the change for #2224. In #2224, a lazy join or include load that failed during a source truncate replay ended the live query. #2168 has since merged to main. Its law 16 makes every lazy demand failure after initial-query readiness a request error, so main now has that part of the change. This PR keeps the four defects that main still has, and the oracle work that found them.

This PR also closes #2221 and the two traces in its comment.

Defects that this PR closes on main

Defect	Found by	Commit
A demand that fails behind a sibling subscription's failed replay publishes the window without its rows	replay-refinement oracle	e8ec44ff8, f9874017e, ported in 3ee776167
A refetch moves a page's end before its tie, and a window move then skips a tied row	ordered-work oracle	21fbd0394, 0bdf113ff
A window move that waits behind a replay drops when a truncate discards that replay (#2221, trace 2)	replay-refinement oracle	ce1299ded, ported in 3ee776167
A short unindexed prefix reads the full source after a refetch (#2221 and its trace 1)	ordered-work oracle	fe48cbe54

All production changes are in @tanstack/db. ARCHITECTURE.md states each rule, and the coverage map records each limit.

Defects that main now closes

This branch also closed these defects. #2168 closes them with its own design, so the merge took main's code for each one. The named replays that found them stay in the oracles, and they pass on the merged code.

Defect	Closed on main by
A lazy demand that fails inside a truncate replay ends the query (#2224)	law 16, and a demand change that starts new demand before it releases retired coverage
A rejected aborted request ends the query with error 228	an abort ends the load, and its later outcome decides nothing
A loadSubset that throws inside a replay ends the query	a synchronous throw is a rejection
A window move settles with its own promise after a newer move throws, or waits on itself	a move can no longer throw

The failure in #2224

The shrunk history is three commands over an ordered window of one row:

hold, truncateMarkers, settle(ok: false)

orderBy rank, limit 1
LEFT JOIN markers, keep unmarked rows
include: toArray(markers where rowId = row.id)
markers: on-demand source

The marker truncate's commit deleted every marker in the private replacement, so the private window moved to row 1. The include's demand changed from {2} to {1}. The controller released {2} before it started {1}, and that release ended the include subscription's replay. So the {1} load started outside any replay, and its failure ended the query with error 228. On main, the demand change now starts {1} before it releases {2}, and law 16 makes the failure a request error.

Shared barrier and failure hold

A query that joins and includes the same source has two subscriptions to it. ARCHITECTURE.md, "Replay participants and failure", now has these rules:

• The subscriptions share one publication barrier. None of their replays publishes, and none whose last demand retired closes, while another of them still has replay work.
• A failed replay of any of them can hold publication. While it does, a lazy demand of any of them that fails after initial-query readiness also fails its own subscription's replacement.
• That hold ends at the first of three events. Every demand load that joins it loads, a later replay of the source succeeds, or the subscription's last demand retires. The query retries the failed demand at once, and the retry joins the hold. Thus the hold ends only after the failed demand's rows load.

Without these rules, one subscription's failed demand can retire, which discards its replay. The other replay then publishes. A later failure finds no failed replay, and the window publishes without that demand's rows. That breaks the promise in #2168 that a failure never takes shown data off the screen.

On main's code, the merge adds failReplacement and the sibling wait to the subscription, and siblingReplays to the builder. failDemand holds the failing subscription's publication when a failed replay of that source holds the barrier.

• Law: ARCHITECTURE.md law 9 and "Replay participants and failure".
• Reach: the replay-refinement oracle generates truncates, held and failing loads, and thrown loads. It also generates aborted requests that resolve or reject, sibling subscriptions, and peer queries. Some histories start during the initial preload. failedSiblingDemandFailures and partialFailureRetirements reach their declared minimums in each failed-replay campaign.
• Observation: the oracle checks retained publication after each step, and the settled window with each row's markers. It also checks live-query status, and convergence after a final truncate of every source.
• RED: the failed-replay random campaign at five times its run count found the trace. Its named replay fails with retained publication after mark: expected [] to deeply equal [ { id: 4, rank: 40, ... } ]. On main's code without the port, that replay and both failed-replay campaigns fail.
• GREEN: the replay-refinement oracle passes 53 of 53 on the merged code.
• Mutants: without failReplacement, the named replay fails. Without the sibling wait, the named replay and both failed-replay campaigns fail with retained publication after move.
• Limits: with a peer query, the retention law does not judge the barrier, because the adapter cannot tell which query started a load.

Ordered loading

Prefix growth (#2221 and its trace 1)

An ordered, limited window over a source without an order index read the whole source when its bounded prefix left the window short. That read has no bound. The prefix now grows instead. It doubles the last prefix while growth still adds rows, and it never reads the full source.

• Law: after a signalling refetch, a bounded recovery read starts no full-source request unless a bounded page ended on a null or NaN rank. ARCHITECTURE.md: "an underfilled unindexed prefix grows".
• Reach: ordered-work.eager-unindexed-refetch (deterministic and random) declares windows that the prefix fills and windows that it leaves short. Sixteen new optimistic-window cases cover a one-row unindexed window behind a joined or anti-joined filter.
• RED: the Ordered window starts two full-source reads after a signalling refetch with a NaN boundary #2221 seed -1142653059 reads the full source twice (expected 2 to be 1). Trace 1, seed -1572621508, fails with expected 2 to be +0. The deterministic unindexed-refetch campaign fails the same law.
• GREEN: all three pass and read no full source after the refetch.
• Mutants: with no stop rule, ordered loading did not reach a fixed point. A rule that stops whenever the prefix reads short leaves the 16 optimistic cases empty after settlement. An unbounded growth read fails 24 cases with an allowed refill used an unbounded provider request.
• Limits: the new optimistic cases use pinned histories with one-row windows. Growth has a bound on its request count, but that count is not minimal.

A refetch that moves a page's end

The ordered-work campaign found seed -1160947149 on main. A refetch moved the first page's end earlier, from rank 2 to rank 0. Row 11 also has rank 0, but no answer held it. The loader ignored the report because its window was inside its own first page. A later window move then read local rows and skipped row 11.

The loader now ignores a report in two cases only. Its own page read past the window, or it read the tie of the page's current end. In other cases it starts its bounded repair.

• Law: ARCHITECTURE.md, the loaded-subset report paragraph.
• Reach: ordered-loader.unproven-report (1,000 runs) starts each history with one of several prefixes. It requires at least 20 histories for each premise.
• RED: on main, seed -1160947149 fails with rows after step 4: expected [ null, +0, 2 ] to deeply equal [ null, +0, +0 ]. The request-authority replay fails with unproven report: ... issued no repair.
• GREEN: both pass. The ordered source loader state oracle passes 77 of 77.
• Mutants: delete the early return or its past-window term: ignored report: request 2 was read for a report over coverage that the loader's own first page proves. Delete the owed-repair term: owed repair: request 2, an ordinary read, came before the repair a report owed. Force a full-source repair after a report: issued no bounded repair and no tie of its end.
• Limits: no oracle distinguishes the Object.is term, which ignores a report when the loader read the current end's tie. It decides differently from its fallback only while other work is in flight, and the quiet premise of the ignored-report law excludes that state. The coverage map records this.

Window moves

ARCHITECTURE.md says that a move that starts during a replay waits for it and applies after the replacement completes. In trace 2 of #2221, a source truncate discarded the replay that a one-row move waited for. The move rejected with AbortError, so the three-row window stayed.

The deferred move now waits for each replay that still holds publication, and then applies. A reload of the query or of a source ends the sync run that the move waits in, and then the move rejects. #2168's source-health oracle requires that.

• RED: on main, the named replay fails with settled window: expected [ 10, 20, 30 ] to deeply equal [ 10 ]. Without the wait loop, 8 tests fail on the merged code, including that replay and the discarded-replay replays.
• GREEN: the replay-refinement and source-health oracles pass, 654 tests in total.
• Mutant: a loop that waits through every rejection fails two named source-health replays and that oracle's generated campaign. One of the replays is "a reload aborts a window move that waits for an earlier replay".
• Limits: the deferred path needs a newer move inside the microtask gap between a replay settling and the deferred move resuming. The grammar does not reach that gap.

Maintainer decisions

• A deferred window move whose replay fails rejects with that replay's own error, its earliest failure that still decides it. Before, the move rejected with the query's latest subset error. On the parent code, both failed-replay campaigns fail the new identity law. The named replay "a window move behind a replay with two failed loads" fails it too.
• The prefix grows. It does not fall back to a full-source read, because that read has no bound. feat: add Convex collections with local live queries and transactions #2230 had let an unindexed joined window read the full source after a refetch, and the merge keeps the stricter law. feat: add Convex collections with local live queries and transactions #2230's new named test passes under it.
• The tie-only read for a moved page end is gone, to save shipped bytes. That read saved one page request for each such refetch. Such a refetch now starts the bounded repair.
• fix(electric): release the shape stream's visibility listener on cleanup #2257 (its review item CF01) required a fresh keyed request that a marker truncate's commit starts to end the query. The first merge kept the Ordered-replay oracle: terminal error after a failed settle following truncate markers #2224 law instead. feat(db): split Collection status from sync errors; add reload() and cleanup admission #2168 then made both demand origins request errors, which agrees with that choice.
• The merge with feat(db): split Collection status from sync errors; add reload() and cleanup admission #2168 takes main's design where it covers this branch's changes:
  • The strict terminal-error law becomes law 16, judged strictly. A terminal error is legal only after a load failed while the query was still loading. The oracle adopts feat(db): split Collection status from sync errors; add reload() and cleanup admission #2168's request-error witness.
  • A synchronous loadSubset throw is a rejection whose owner's release unloads it, as main's subscription tests require. The replay oracle now counts a thrown load as acquired. ARCHITECTURE.md and the glossary's "acquisition attempt" entry had said that no unload happens, and they now agree with the code.
  • The window-request reset is gone. A move can no longer throw, and deleting the reset failed nothing.
• Expectation changes:
  • The existing unindexed optimistic cases behind a joined filter now allow a request when the source already holds the replacement row. They do not require it. Growth proves rows only up to its prefix.
  • The optimistic refill bound for unindexed plans is two times the installed prefix, plus the overlaid row.
  • One older named replay required a deferred move to reject with AbortError. The contract does not promise that, so the replay now checks the moved window.

Oracle changes from reviews and merges

• After initial-query readiness, the replay oracle checks each history cut. The query's own node must list each owed request failure, by its injected error. No request error may stay after recovery. A mutant that never reports demand request errors fails 9 tests, and a mutant that keeps them after a successful replay fails 22.

• A terminal error needs a failure while that same query was loading, so a peer's initial failure no longer excuses the other query.

• The window check requires each shown row to be eligible and to appear once. Thus a tie cannot hide a row that the join rejects.

• The cost law rejects a repeated read within one invalidation.

• The Query DB refetch campaigns declare reach with createOracleReach (minimum 3). Each measured reach is at least 2.8 times its minimum.

• The replay oracle treats a synchronous setWindow throw as an escaped error, since a throw is now a rejection.

• The replay oracle keeps fix(electric): release the shape stream's visibility listener on cleanup #2257's named replays and its two campaigns, replay.subscription-demand-origin and replay.keyed-request-failures, on this branch's model. Both demand origins must stay nonterminal, and new demand that fails must leave a request error.

• The replay manifest names an owner and a replay selector for each of this branch's five oracle properties. Each guarded replay runs one execution.

Limits

• With a peer query, the retention law does not judge the barrier.
• A design that drops a thrown demand and lets its replay succeed passes wherever only retention could see it.
• The replay oracle drives a failed replacement's hold only through live-query histories, where the query retries the failed demand at once. A direct Collection.subscribeChanges caller that never retries is outside the live-query contract. A review found that the hold can end when a later demand joins it and loads. By maintainer decision, the law now permits this, because the retry of the failed demand joins the hold (ARCHITECTURE.md, "Replay participants and failure"). The request-error account now judges each subscription by the subscription that a load names. The failed-replay campaigns reach that state in 54 histories (30 seeded and 24 random). A mutant that ends the hold when any participant settles fails both campaigns at the retention law. This branch deletes the it.fails test that pinned the earlier wording.
• The replay error identity law judges only a deferred move that starts before any failure of the replays it waits on.
• Random runs that pass are not a proof. The stated grammar, production path, and checkpoints bound each claim above.

Code weight

pnpm size:compare against origin/main (db476b8ed):

Bundle	Δ gzip	Δ brotli
@tanstack/db	+355 B (+0.3%)	+343 B
app scenario	+342 B (+0.4%)	+198 B

The other packages do not change. The remaining growth pays for the four defects above.

The merge with #2168 deleted this branch's code wherever main already covered the behavior. It deleted the error-228 rule outside a replay and the replay that a truncate opened without demand. It also deleted the synchronous-throw and aborted-request handling, and the window-request reset. Before that merge, these changes deleted bytes:

Change	Δ gzip
Close the report path's guards with laws, and delete two terms that other checks decide	−4 B
Drop the tie-only read for a moved page end	−127 B
Fold the shared-barrier check into the builder's failDemand	−21 B
Give siblingReplays the subscriber's collection	−6 B
Drop a check in failReplacement that its only caller cannot fail	−5 B

I tried these changes and rejected them:

• A getter that returned a replay's completion only while it had work grew gzip by 4 B.
• Deleting the canExpressCursorOrder term let an unindexed loader read the full source (seed 1620448148).

Tests, ARCHITECTURE.md, the changeset, and the coverage map grow separately.

Verification

• After the merge with feat(db): split Collection status from sync errors; add reload() and cleanup admission #2168, the @tanstack/db suite passes 15,520 of 15,521 tests in 298 files. The one failure was a random-seed reach miss in the GC oracle from fix(db): keep a collection from garbage collection while its transaction persists #2258 (restarted-after-retirement (0)). That test passes in 3 of 3 reruns.
• After that merge, the @tanstack/query-db-collection suite passes: 42 files and 1,492 tests, with 2 skipped.
• After the merge with feat: add Convex collections with local live queries and transactions #2230, the ordered-work, joint-replay, oracle-campaign, and oracle-replay files pass: 343 tests.
• After the review of the merge, the @tanstack/db suite passes: 300 files and 15,528 tests. The replay-refinement oracle passes 53 of 53 at the normal and at three times the run budget.
• tsc, ESLint, Prettier, pnpm lint:changed, and the mangle check pass.

Closes #2224, closes #2221

Walkthrough

Truncate replay now separates recovery work from replay setup. Ready live queries retain their last complete publication after a replay load failure, while failures before initial readiness remain fatal. Aborted obsolete subset requests do not propagate as load failures. Ordered-window coverage now requires loader-specific evidence and triggers repair when that evidence is absent.

Changes: Live query replay

Layer / File(s)	Summary
Truncate replay and demand replacement packages/db/src/collection/subscription.ts, packages/db/src/query/live/subset-demand-controller.ts, packages/db/src/query/live/collection-config-builder.ts, packages/db/src/query/live/ARCHITECTURE.md, packages/db/tests/query/ordered-lifecycle-oracle.property.test.ts	Truncate handling starts recovery only when demands need reloading or published rows remain. New demand segments start before retired segments are released. Deferred window moves wait for pending recovery. The replay tests check truncate behavior at limits zero and one.
Replay failure and aborted demand handling packages/db/src/query/live/collection-config-builder.ts, packages/db/src/query/live/collection-subscriber.ts, packages/db/src/query/live/subset-demand-controller.ts, packages/db/src/query/live/ARCHITECTURE.md, packages/db/tests/query/load-subset-replay-refinement-oracle.test.ts, .changeset/keep-live-query-through-failed-replay.md	failDemand now accepts a fatal flag and still transitions a loading query to error. Failed replay demands do not end an already-ready query. Rejected aborted requests adopt pending replacement state or resolve without propagating the request error. Oracle histories cover replay failures, aborted requests, and replay during initial preload.
Ordered-window proof and repair packages/db/src/query/live/ordered-source-loader.ts, packages/db/tests/query/ordered-source-loader-state-oracle.test.ts, packages/db/tests/query/ordered-work-oracle.property.test.ts, packages/query-db-collection/tests/refetch-ordered-prefix-oracle.test.ts, packages/db/mangle-cache.json, docs/contributing/oracle-coverage.md	Ordered-page coverage requires evidence from the page read or its current end tie. Unproven reports trigger repair. Tests cover shifted boundaries, short prefixes, tie requests, and retained active Query counts.

Full details: Linked Issues check

Explanation

Issue #2224 is the only active directly linked issue. The production changes address its shrunk history. subset-demand-controller.ts starts replacement demand before releasing obsolete demand. subscription.ts opens a truncate replay for acquiring on-demand subscriptions. collection-subscriber.ts and collection-config-builder.ts keep a failed replay demand non-fatal after the query is ready, while failures during loading remain fatal. The replay-refinement oracle now models recovery ownership and covers the reported seed and path. The reported named replay passes on this branch.

Full details: Description check

Explanation

The description is highly complete and covers the change scope, defect motivation, oracle coverage, laws, RED/GREEN evidence, mutants, limits, release impact, changeset, and verification results. It does not use the template headings or include the checklist and release-impact checkboxes verbatim, but the required information is present and clearly documented.

Full details: Out of Scope Changes check

Explanation

The ordered page-end repair is unrelated to #2224. ordered-source-loader.ts adds revalidateLoadedCoverage, ownPrefixEnd, and loadMovedEndTie for a separate signalling-refetch defect with no truncate replay or terminal query error. The related oracle laws, Query DB test, architecture and coverage documentation, changeset entry, and mangle-cache.json updates support that separate behavior. The PR also includes a separate discarded-replay window-move fix; its connection to the linked counterexample is not established, although it is adjacent to replay handling.

Resolution

Remove the ordered page-end repair and its dedicated tests, oracle changes, documentation, changeset text, and mangle-cache.json entries, or move them to a separate pull request linked to an issue for that defect. Also provide a concrete #2224 connection for the discarded-replay window-move change or move that change to the related pull request.

Defer the proof assertion during replay or after disposal.

truncate preserves owedProof, but replay does not issue requests until it settles. A disposed loader owes no further proof. The current check can therefore fail an allowed history and make test:oracles fail. settleReplay does not clear the obligation; a later joinedIdle can validate and clear it.

Suggested fix

-          if (owedProof) {
+          if (owedProof && !truncatePending && !disposed) {

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	if (owedProof) {
	expectProofRequest(owedProof.from, owedProof.windowSize)
	owedProof = undefined
	repairedReportsOnOwnPage++
	if (owedProof && !truncatePending && !disposed) {
	expectProofRequest(owedProof.from, owedProof.windowSize)
	owedProof = undefined
	repairedReportsOnOwnPage++
