Looks good! It would be great to see a few approvals from devs before merging it

This is used by cell-level dissemination (aka partial messages) to give the CL all blobs the EL knows about and let CL communicate efficiently about any other missing blobs. In other words, partial responses from the EL is useful now. See the related (closed) PR: ethereum/execution-apis#674 and the new PR: ethereum/execution-apis#719

With the current state sizer, whenever the node is stopped, the background process must be freshly initialized. During this re-initialization, it can skip some blocks while the node continues executing blocks, causing gaps in the recorded metrics. Using this state update hook allows us to customize our own data persistence logic, and we would never skip blocks upon node restart. --------- Co-authored-by: Gary Rong <[email protected]> commit 957a360 Author: cui <[email protected]> Date: Wed Jan 7 10:02:27 2026 +0800 core/vm: avoid escape to heap (ethereum#33537) commit 7100084 Author: Csaba Kiraly <[email protected]> Date: Wed Jan 7 02:52:50 2026 +0100 eth: txs fetch/send log at trace level only (ethereum#33541) This logging was too intensive at debug level, it is better to have it at trace level only.

Verified build with make geth commit d9aaab1 Author: Fibonacci747 <[email protected]> Date: Tue Dec 30 18:27:11 2025 +0100 beacon/light/sync: clear reqFinalityEpoch on server unregistration (ethereum#33483) HeadSync kept reqFinalityEpoch entries for servers after receiving EvUnregistered, while other per-server maps were cleared. This left stale request.Server keys reachable from HeadSync, which can lead to a slow memory leak in setups that dynamically register and unregister servers. The fix adds deletion of the reqFinalityEpoch entry in the EvUnregistered handler. This aligns HeadSync with the cleanup pattern used by other sync modules and keeps the finality request bookkeeping strictly limited to currently registered servers. commit b3e7d9e Author: rjl493456442 <[email protected]> Date: Tue Dec 30 23:05:13 2025 +0800 triedb/pathdb: optimize history indexing efficiency (ethereum#33303) This pull request optimizes history indexing by splitting a single large database batch into multiple smaller chunks. Originally, the indexer will resolve a batch of state histories and commit all corresponding index entries atomically together with the indexing marker. While indexing more state histories in a single batch improves efficiency, excessively large batches can cause significant memory issues. To mitigate this, the pull request splits the mega-batch into several smaller batches and flushes them independently during indexing. However, this introduces a potential inconsistency that some index entries may be flushed while the indexing marker is not, and an unclean shutdown may leave the database in a partially updated state. This can corrupt index data. To address this, head truncation is introduced. After a restart, any excessive index entries beyond the expected indexing marker are removed, ensuring the index remains consistent after an unclean shutdown. commit b84097d Author: Guillaume Ballet <[email protected]> Date: Tue Dec 30 14:43:45 2025 +0100 .github/workflows: preventively close PRs that seem AI-generated (ethereum#33414) This is a new step in my crusade against the braindead fad of starting PR titles with a word that is completely redundant with github labels, thus wasting prime first-line real-estate for something that isn't necessary. I noticed that every single one of these PRs are low-quality AI-slop, so I think there is a strong case to be made for these PRs to be auto-closed. A message is added before closing the PR, redirecting to our contribution guidelines, so I expect quality first-time contributors to read them and reopen the PR. In the case of spam PRs, the author is unlikely to revisit a given PR, and so auto-closing might have a positive impact. That's an experiment worth trying, imo. commit 3f641db Author: Guillaume Ballet <[email protected]> Date: Tue Dec 30 13:44:04 2025 +0100 trie, go.mod: remove all references to go-verkle and go-ipa (ethereum#33461) In order to reduce the amount of code that is embedded into the keeper binary, I am removing all the verkle code that uses go-verkle and go-ipa. This will be followed by further PRs that are more like stubs to replace code when the keeper build is detected. I'm keeping the binary tree of course. This means that you will still see `isVerkle` variables all over the codebase, but they will be renamed when code is touched (i.e. this is not an invitation for 30+ AI slop PRs). --------- Co-authored-by: Gary Rong <[email protected]> commit 57f8486 Author: Archkon <[email protected]> Date: Mon Dec 29 20:57:29 2025 +0800 params: fix wrong comment (ethereum#33503) It seems that the comment for CopyGas was wrongly associated to SloadGas. commit b9702ed Author: oooLowNeoNooo <[email protected]> Date: Mon Dec 29 09:23:51 2025 +0100 console/prompt: use PromptInput in PromptConfirm method (ethereum#33445) commit 4531bfe Author: rjl493456442 <[email protected]> Date: Mon Dec 29 16:13:30 2025 +0800 eth/downloader: fix stale beacon header deletion (ethereum#33481) In this PR, two things have been fixed: --- (a) truncate the stale beacon headers with latest snap block Originally, b.filled is used as the indicator for deleting stale beacon headers. This field is set only after synchronization has been scheduled, under the assumption that the skeleton chain is already linked to the local chain. However, the local chain can be mutated via `debug_setHead`, which may cause `b.filled` outdated. For instance, `b.filled` refers to the last head snap block in the last sync cycle while after `debug_setHead`, the head snap block has been rewounded to 1. As a result, Geth can enter an unintended loop: it repeatedly downloads the missing beacon headers for the skeleton chain and attempts to schedule the actual synchronization, but in the final step, all recently fetched headers are removed by `cleanStales` due to the stale `b.filled` value. This issue is addressed by always using the latest snap block as the indicator, without relying on any cached value. However, note that before the skeleton chain is linked to the local chain, the latest snap block will always be below skeleton.tail, and this condition should not be treated as an error. --- (b) merge the subchains once the skeleton chain links to local chain Once the skeleton chain links with local one, it will try to schedule the synchronization by fetching the missing blocks and import them then. It's possible the last subchain already overwrites the previous subchain and results in having two subchains leftover. As a result, an error log will printed https://github.com/ethereum/go-ethereum/blob/master/eth/downloader/skeleton.go#L1074

CL clients can make use of partial responses to exchange just the missing cells. This method allows the CL to request partial responses from the EL.
This method is identical to getBlobsV2 but returns null entries if a blob is not available locally.
See https://ethresear.ch/t/gossipsubs-partial-messages-extension-and-cell-level-dissemination/23017 for context on cell level dissemination. See #674 for the prior version of this PR. That PR was closed to avoid adding a new requirement to Fusaka.
The changes here are currently in ./src/engine/osaka.md, but I'm happy to move them to a new file if folks prefer that. Maybe titled osaka-BPO-X.md where X is the BPO number we want these changes to be available in?
Implementing this method is not mandatory as CL clients can fallback to getBlobsV2. However for cell level dissemination to be useful, the EL needs to provide this method.
