The grouping and merge threshold for dynamic contract partitions was a fixed 20k blocks, which on sparse factories produced a large number of partitions per registration wave. Raising it to 50k reduces the partition count at the cost of fetching more discardable pre-registration events per group. https://claude.ai/code/session_01HxQeuZQ11GUAoBZdbFaDuW

- Line 203: The tooFarBlockRange variable in FetchState.res is currently set to
50_000, but the PR summary states it should be increased to 100_000. Update the
tooFarBlockRange assignment to use 100_000 to match the stated PR objective,
ensuring the implementation is consistent with the documented intent.
- Line 203: The tooFarBlockRange threshold in FetchState.res has been increased
from 20,000 to 50,000 blocks. This changes the partition strategy for the E2E
test scenario: the 20,100 block gap between DC1 and DC2 no longer exceeds the
new threshold, so these contracts should now merge into a single partition
instead of remaining separate. Update the test assertion in E2E_test.res
(currently expecting partitions [("2", 5000), ("3", 25100), ("0", 25101)]) to
reflect the new merged partition outcome that results from this increased
threshold.

Inconsistency between PR objectives and implementation.
The PR summary states the threshold is increased to 100,000, but the actual code shows 50,000. Please confirm which value is intended.

Update E2E test expectations for new partition threshold.
The E2E test (E2E_test.res, line 1323) expects DC1 and DC2 to occupy separate partitions based on a gap of 20,100 blocks exceeding the old threshold of 20,000. With the new threshold of 50,000, this gap no longer exceeds the threshold, changing the partition strategy to merge. The assertion at line 1357 expects partitions [("2", 5000), ("3", 25100), ("0", 25101)] and will fail because the contracts should now be merged into a single partition instead of remaining separate.

Summary
Increases the
tooFarBlockRangeconstant inFetchState.OptimizedPartitionsfrom 20,000 to 100,000 blocks. This threshold determines when partition start blocks are considered "too far apart" and triggers partition merging logic.Changes

The
tooFarBlockRangeconstant is used by the partition optimization logic to determine when event configs with distant start blocks should be merged together. By increasing this threshold from 20k to 100k blocks, the optimization becomes more conservative about merging partitions, allowing for better parallelization of data fetching across a wider block range before triggering merges.The test changes maintain the same logical behavior while making the tests more maintainable by centralizing the threshold value.
