3d35cc20ec Use WriteStateFetchError in API handlers whenever possible (#16140)
**What type of PR is this?**

Other

**What does this PR do? Why is it needed?**

Calls to `Stater.StateBySlot` and `Stater.State` should be followed by
`shared.WriteStateFetchError` to provide the most robust error handling.

Design Doc

**What does this PR do? Why is it needed?**

This PR adds a design doc for adding graffiti. The idea is to have it
populated judiciously so that we can get proper information about the
EL, CL and their corresponding version info. At the same time being
flexible enough with the user input.

**What does this PR do? Why is it needed?**

- Remove unnecessary `Copy()` call in `Eth1DataHasEnoughSupport`
- `data.Copy()` was called on every iteration of the vote counting loop,
even though `AreEth1DataEqual` only reads the data and never mutates it.
- Additionally, `Eth1DataVotes()` already returns copies of all votes,
so state is protected regardless.

**What does this PR do? Why is it needed?**

The for loop in MigrateToCold function was brute force in nature. It
could be improved by just directly jumping by `slotsPerArchivedPoint`
rather than going over every single slot.

```
for slot := oldFSlot; slot < fSlot; slot++ {
  ...
   if slot%s.slotsPerArchivedPoint == 0 && slot != 0 {
```
No need to do the modulo for every single slot.
We could just find the correct starting point and jump by
slotsPerArchivedPoint at a time.

5a2e51b894 fix(rpc): incorrect constructor return type (#16084)
The constructor `NewStateRootNotFoundError` incorrectly returned
`StateNotFoundError`. This prevented handlers that rely on
errors.As(err, *lookup.StateRootNotFoundError) from matching and mapping
the error to HTTP 404. The function now returns
StateRootNotFoundError and constructs that type, restoring the intended
behavior for “state root not found” cases.

fa056c2d21 Move the "Not enough connected peers" (for a given subnet) from WARN to DEBUG (#16087)
**What type of PR is this?**
Other

**What does this PR do? Why is it needed?**
Move the "Not enough connected peers" (for a given subnet) from WARN to
DEBUG

**Rationale:**
The
<img width="1839" height="31" alt="image"
src="https://github.com/user-attachments/assets/44dbdc8d-3e37-42ee-967b-75a7a1fbcafb"
/>
log is (potentially) printed every 5 minutes.
Every 5 minutes, the BN checks if, for a given subnet, the actual count
of peers is at least equal to a minimum one.
If not, this kind of log is printed.

When validators are connected and selected to be an aggregator in the
next epoch, the BN needs to subscribe and find new peers in the
corresponding attestation subnet.
If, right after the beacon is subscribed (but before it had time to find
peers), the "5 min ticker" ticks, then this warning log is displayed,
even if the slot for which the validator is selected as an aggregator is
still minutes away.

For this reason, this log is moved from WARN to DEBUG

08d0f42725 beacon-chain/das: remove dead slot parameter (#16021)
The slot parameter in blobCacheEntry.filter was unused and redundant.
All slot/epoch-sensitive checks happen before filter
(commitmentsToCheck), and disk availability is handled via
BlobStorageSummary (epoch-aware).

Changes:
- Drop slot from blobCacheEntry.filter signature.
- Update call sites in availability_blobs.go and blob_cache_test.go.

Mirrors the data_column_cache.filter API (which does not take slot),
reduces API noise, and removes dead code without changing behavior.

Pro:
- We are useful to the network
- Less disconnection likelihood
- Straight forward to implement

Con:
- We cannot revert to a full node
- We have to serve incoming RPC requests corresponding to 64 columns

6be1541e57 Initialize the ExecutionRequests field in gossip block map (#16047)
**What type of PR is this?**

Other

**What does this PR do? Why is it needed?**

When unmarshaling a block with fastssz, if the target block's
`ExecutionRequests` field is nil, it will not get populated
```
if b.ExecutionRequests == nil {
	b.ExecutionRequests = new(v1.ExecutionRequests)
}
if err = b.ExecutionRequests.UnmarshalSSZ(buf); err != nil {
	return err
}
```
This is true for other fields and that's why we initialize them in our
gossip data maps. There is no bug at the moment because even if
execution requests are nil, we initialize them in
`consensus-types/blocks/proto.go`
```
er := pb.ExecutionRequests
if er == nil {
	er = &enginev1.ExecutionRequests{}
}
```
However, since we initialize other fields in the data map, it's safer to
do it for execution requests too, to avoid a bug in case the code in
`consensus-types/blocks/proto.go` changes in the future.

b845222ce7 Integrate state-diff into HasState() (#16045)
**What type of PR is this?**
Feature

**What does this PR do? Why is it needed?**
This PR adds integrates state-diff into `HasState()`. 

One thing to note: we are assuming that, for a given block root, that
has either a state summary or a block in db, and also falls in the state
diff tree, then there must exist a state. This function could return
true, even when there is no actual state saved due to any error.
But this is fine, because we have that assumption throughout the whole
state diff feature.

26100e074d Refactor slot by blockroot (#16040)
**Review after #16033 is merged**

**What type of PR is this?**
Other

**What does this PR do? Why is it needed?**
This PR refactors the code to find the corresponding slot of a given
block root using state summary or the block itself, into its own
function `SlotByBlockRoot(ctx, blockroot)`.

Note that there exists a function `slotByBlockRoot(ctx context.Context,
tx *bolt.Tx, blockRoot []byte)` immediately below the new function. Also
note that this function has two drawbacks, which led to creation of the
new function:
- the old function requires a boltdb tx, which is not necessarily
available to the caller.
- the old function does NOT make use of the state summary cache. 

edit: 
- the old function also uses the state bucket to retrieve the state and
it's slot. this is not something we want in the state diff feature,
since there is no state bucket.

11bb8542a4 Integrate state-diff into State() (#16033)
**What type of PR is this?**
Feature

**What does this PR do? Why is it needed?**
This PR integrates the state diff path into the `State()` function from
`db/kv`, which allows reading of states using the state diff db, when
the `EnableStateDiff` flag is enabled.

**Notes for reviewers:**
Files `kv/state_diff_test.go` and `config/features/config.go` only
contain renamings:
- `kv/state_diff_test.go`: rename `setDefaultExponents()` to
`setDefaultStateDiffExponents()` to be less vague.
- `config/features/config.go`: rename `enableStateDiff` to
`EnableStateDiff` to make it public.

This PR adds a Summary metric to measure the p2p topic validation time
for attestations arriving from the network. It times the
`validateCommitteeIndexBeaconAttestation` method.

The metric is called `gossip_attestation_verification_milliseconds`

5449fd0352 p2p: wire stategen into service for last finalized state (#16034)
This PR removes the last production usage for: `LastArchivedRoot` by

- extend the P2P config to accept a `StateGen` dependency and wire it up
from the beacon node
- update gossip scoring to read the active validator count via stategen
using last finalized block root

note: i think the correct implementation should process last finalizes
state to current slot, but that's a bigger change i dont want to make in
this PR, i just want to remove usages for `LastArchivedRoot`

3d7f7b588b Fix state diff repetitive anchor slot bug (#16037)
**What type of PR is this?**
 Bug fix

**What does this PR do? Why is it needed?**
This PR fixes a bug in the state diff `getBaseAndDiffChain()` method. In
the process of finding the diff chain indices, there could be a scenario
where multiple levels return the same diff slot number not equal to the
base (full snapshot) slot number.
This resulted in multiple diff items being added to the diff chain for
the same slot, but on different levels, which resulted in errors reading
the diff.

Fix: we keep a `lastSeenAnchorSlot` equal to the `BaseAnchorSlot` and
update it every time we see a new anchor slot. We ignore if the current
found anchor slot is equal to the `lastSeenAnchorSlot`.

Scenario example: 
exponents: [20, 14, 10, 7, 5]
offset: 0
slots saved: slot 2^11, and slot (2^11 + 2^5)
slot to read: slot (2^11 + 2^5)
resulting list of anchor slots (diff chain indices): [0, 0, 2^11, 2^11,
2^11 + 2^5]
