Frozen reduction: Retire internal Scheduler.onClear notifications and pending-aware dependency objects because production has no callers. Dependencies then wait only for queued jobs. Replace synthetic tests with queued-job cancellation, exact failure identity, and recovery checks. Remove Effect's retained pipeline and tracksPublishedRows fields because the first is used once and the second duplicates the ordered-loader map. Remove unused scheduleGraphRun job ID and dependency overrides.

The before source is commit 80421c8b. The after source is code commit b69c189c. Two agents scanned the source versions separately after reading the field-lab loss-audit card and live-query architecture. The entries below are source-supported omissions from the frozen reduction. They do not decide whether to restore an item or whether a behavior regressed.

Source	Recovered distinction and pointer	Where dropped	Rule
Before scheduler	A dependency could block through hasPendingGraphRun(contextId) even without a queued job. Otherwise an absent dependency was satisfied (80421c8b:scheduler.ts:126-144).	Queued-only clause	Explicit rejection
Before scheduler	Rescheduling replaced a callback without moving its queue position; omitted dependencies retained the prior set. A running job left the map before reentrant work (scheduler.ts:84-101,147-152).	Cancellation clause	Compression
Before scheduler	clear() deleted the context before notifying a listener snapshot; onClear() returned an unsubscribe callback (scheduler.ts:171-183).	Retire onClear clause	Explicit rejection
Before scheduler	Nested publications shared a context. Recorded listener failure preceded later graph failure; clearing could not replace the primary error (scheduler.ts:188-245).	Failure-identity clause	Compression
Before Effect	The compiler's pipeline received its output operator before finalization and was cleared with graph/input references on disposal (effect.ts:386-389,467-503,1096-1101).	One-use field clause	Compression
Before Effect	tracksPublishedRows was set before the ordered loader started and selected callback-visible membership classification rather than immediate delta classification (effect.ts:571-664,948-968,1156-1197).	Duplicate-state clause	Explicit rejection
Before Effect	Ordered repair held callback delivery across participants and could transfer that hold to truncate replay. publishedRows retained the prior visible values (effect.ts:409-428,819-861,924-968).	Field-removal clause	Category mismatch
Before Effect	Source live-query builders became graph dependencies during subscription and were passed to the shared scheduler (effect.ts:548-553,803-817).	Queued-only clause	Compression
Before builder	contextId remained a live override beside the unused job ID and dependency overrides. The queued callback was fenced by sync-run generation (collection-config-builder.ts:651-691).	Override clause	Compression
Before builder	Window moves, demand settlement, ordered-load completion, initial sync, and source recovery each scheduled graph work (collection-config-builder.ts:336-339,406-416,491-528,762-766,1091-1105).	Override clause	Low salience
Before builder	Even an initially empty graph turn checked loaders, processed synchronous writes through D2, flushed, then evaluated readiness (collection-config-builder.ts:571-645).	Queue clause	Category mismatch
Before builder	Ordered-load settlement checked sync-run identity before changing failure state. Its final success scheduled a publication run (collection-config-builder.ts:491-528).	Recovery clause	Compression
Before scheduler test	The dependency matrix crossed source order, pending-aware state, and requeue. It required the dependent to see the final source run (scheduler.test.ts:132-179).	Synthetic-test replacement clause	Category mismatch
Before scheduler test	The clear-listener test checked listener snapshot mutation, multiple failures, first-error retention, and the next clear (scheduler.test.ts:280-313).	Retire onClear clause	Explicit rejection
Before scheduler test	Publication tests checked nested timing, discarded jobs, first-error precedence, thrown undefined, later delivery, and coherent dependent state (scheduler.test.ts:182-278,579-727).	Failure-identity clause	Compression
Before scheduler test	Collection/Effect cases crossed shared and derived sources plus write order; diamond and hybrid joins required one coherent dependent run (scheduler.test.ts:1059-1367).	Synthetic-test replacement clause	Category mismatch
Before scheduler test	Restart cases separated obsolete resolve/reject from replacement state; loader cases checked writes during graph turns (scheduler.test.ts:1443-1631).	Recovery clause	Compression
Before scheduler test	Repeated lexical aliases attempted every loader and kept the exact first falsy failure (scheduler.test.ts:1633-1771).	Failure-identity clause	Compression
After scheduler	Rescheduling replaces a callback while retaining queue position; omission of new dependencies retains the old set (scheduler.ts:70-94).	Queued-only clause	Compression
After scheduler	A running prerequisite leaves the map before its callback; requeueing it blocks its dependent. A no-progress pass throws (scheduler.ts:98-145).	Queued-only clause	Compression
After scheduler	Nested publications share the outer context. Graph work flushes afterward; the first listener error has precedence, and failure clears jobs/context (scheduler.ts:173-226).	Failure/recovery clause	Compression
After Effect	Compiler closures retain mutable subscriptions. Startup buffers changes until subscriptions exist, drains them to D2, then runs the graph (effect.ts:389,519-750).	One-use pipeline clause	Category mismatch
After Effect	The ordered-loader map supplies the tracking condition; the separate publishedRows map retains callback-visible membership and values (effect.ts:405,939-959,1150).	Duplicate-state clause	Compression
After Effect	Ordered repair and inherited replay holds still gate callbacks across participants. Final success flushes; failure keeps private deltas hidden (effect.ts:814-861).	Field-removal clause	Low salience
After builder	contextId, builder dependencies, and sync-run fencing remain in scheduleGraphRun (collection-config-builder.ts:651-685).	Override clause	Compression
After builder	Empty-start graph turns still check loaders and process synchronous writes before publication (collection-config-builder.ts:571-645).	Queue clause	Category mismatch
After builder	Ordered-load settlement is sync-run-fenced. Window failures, replay, ordered loads, and joined demand still gate publication (collection-config-builder.ts:491-528,908-936).	Recovery clause	Compression
After builder	Child facades prepare before root commit; failure discards them, while root and facade notifications follow state installation (collection-config-builder.ts:930-981).	Scheduler-focused reduction	Low salience
After scheduler test	Source/dependent order and prerequisite requeue form a four-case matrix that checks the final source run (scheduler.test.ts:132-165).	Cancellation clause	Compression
After scheduler test	Listener snapshot, first-error, later delivery, and falsy-failure matrices remain in public publication-path tests (scheduler.test.ts:388-727).	Failure/recovery clause	Compression
After scheduler test	Collection/Effect, shared/derived, write-order, diamond, and hybrid cases check coherent dependent publication (scheduler.test.ts:1035-1367).	Synthetic-test replacement clause	Category mismatch
After scheduler test	Restart and repeated-alias cases retain stale-settlement and exact first-failure distinctions (scheduler.test.ts:1419-1771).	Recovery clause	Compression

The before-only scan cannot establish repository-wide caller absence. The separate repository search found no production call to onClear() or implementation of hasPendingGraphRun() at the code target. The after-only scan found no explicit rejection in the frozen summary. Each scan returned its own source pointers before collation.
