Automated backport of #3554 to stable (backport job run).

AI recommendation: This is a pure correctness fix (patch changeset) for a replay-determinism defect that produces CORRUPTED_EVENT_LOG — step correlation ids depended on how much of the event log an invocation had loaded, so concurrent replays committed conflicting bindings and one logical step ran under two ids. The affected machinery already exists on stable (packages/core/src/private.ts there has the same pendingDeliveryBarriers registry, awaitEarlierDeliveries, hasParkedCommittedDelivery, and the per-barrier scheduleWhenIdle safety net this replaces), and the rest of the commit is regression tests plus a fixture. No new API surface or feature work is added.

Automated backport of #3554 to stable (backport job run).
AI recommendation: This is a pure correctness fix (patch changeset) for a replay-determinism defect that produces CORRUPTED_EVENT_LOG — step correlation ids depended on how much of the event log an invocation had loaded, so concurrent replays committed conflicting bindings and one logical step ran under two ids. The affected machinery already exists on stable (packages/core/src/private.ts there has the same pendingDeliveryBarriers registry, awaitEarlierDeliveries, hasParkedCommittedDelivery, and the per-barrier scheduleWhenIdle safety net this replaces), and the rest of the commit is regression tests plus a fixture. No new API surface or feature work is added.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-5). Please review the conflict resolution carefully before merging.

Automated backport of #3554 to stable (backport job run).
AI recommendation: This is a pure correctness fix (patch changeset) for a replay-determinism defect that produces CORRUPTED_EVENT_LOG — step correlation ids depended on how much of the event log an invocation had loaded, so concurrent replays committed conflicting bindings and one logical step ran under two ids. The affected machinery already exists on stable (packages/core/src/private.ts there has the same pendingDeliveryBarriers registry, awaitEarlierDeliveries, hasParkedCommittedDelivery, and the per-barrier scheduleWhenIdle safety net this replaces), and the rest of the commit is regression tests plus a fixture. No new API surface or feature work is added.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-5). Please review the conflict resolution carefully before merging.

Automated backport of #3554 to stable (backport job run).
AI recommendation: This is a pure correctness fix (patch changeset) for a replay-determinism defect that produces CORRUPTED_EVENT_LOG — step correlation ids depended on how much of the event log an invocation had loaded, so concurrent replays committed conflicting bindings and one logical step ran under two ids. The affected machinery already exists on stable (packages/core/src/private.ts there has the same pendingDeliveryBarriers registry, awaitEarlierDeliveries, hasParkedCommittedDelivery, and the per-barrier scheduleWhenIdle safety net this replaces), and the rest of the commit is regression tests plus a fixture. No new API surface or feature work is added.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-5). Please review the conflict resolution carefully before merging.

Automated backport of #3554 to stable (backport job run).
AI recommendation: This is a pure correctness fix (patch changeset) for a replay-determinism defect that produces CORRUPTED_EVENT_LOG — step correlation ids depended on how much of the event log an invocation had loaded, so concurrent replays committed conflicting bindings and one logical step ran under two ids. The affected machinery already exists on stable (packages/core/src/private.ts there has the same pendingDeliveryBarriers registry, awaitEarlierDeliveries, hasParkedCommittedDelivery, and the per-barrier scheduleWhenIdle safety net this replaces), and the rest of the commit is regression tests plus a fixture. No new API surface or feature work is added.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-5). Please review the conflict resolution carefully before merging.

Automated backport of #3554 to stable (backport job run).
AI recommendation: This is a pure correctness fix (patch changeset) for a replay-determinism defect that produces CORRUPTED_EVENT_LOG — step correlation ids depended on how much of the event log an invocation had loaded, so concurrent replays committed conflicting bindings and one logical step ran under two ids. The affected machinery already exists on stable (packages/core/src/private.ts there has the same pendingDeliveryBarriers registry, awaitEarlierDeliveries, hasParkedCommittedDelivery, and the per-barrier scheduleWhenIdle safety net this replaces), and the rest of the commit is regression tests plus a fixture. No new API surface or feature work is added.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-5). Please review the conflict resolution carefully before merging.
