## Summary
The existing fungible migration code has an issue when handling
partially unbonding accounts, leaving them in an inconsistent state.
These changes fix it by properly withdrawing overstake from unlock
chunks.

This PR also removes the `withdraw_overstake` extrinsic from
pallet-staking, as this scenario could only occur before the fungible
migration. With fungibles, over-staking is no longer possible.

## TODO
- [ ] Backport to stable2503.

This PR makes the litep2p backend the default network backend in Kusama.

We performed a gradual rollout in Kusama by asking validators to
manually switch to litep2p. The rollout went smoothly, with 250
validators running litep2p without issues. This PR represents the next
step in testing the backend at scale.

Thanks to everyone who contributed to making this happen! A special
shoutout to the validators for their prompt support and cooperation 

While at it, the litep2p release is bumped to the latest 0.9.2, which
downgrades a spamming log to debug.


### CLI Testing Done

[pallet-revive] Add support for eip1898 block notation
https://eips.ethereum.org/EIPS/eip-1898

Co-authored-by: cmd[bot] <41898282+github-actions[bot]@users.noreply.github.com>

This PR includes:

- deduplicating some XCM decoding logic
- making use of `decode_with_depth_limit` consistently for
`VersionedXcm`
- some cleanup

**Summary:** This PR enables authoring of multiple blocks in one AURA
slot in the slot-based collator and stabilizes the slot-based collator.

## CLI Changes
The flag `--experimental-use-slot-based` is now marked as deprecated. I
opted to introduce `--authoring slot-based` instead of just removing the
`experimental` prefix. By introducing the `authoring` variant, we get
some future-proofing in case we want to introduce further options.

## Change Description
With elastic-scaling, we are able to author multiple blocks with a
single relay-chain parent. In the initial iteration, the interval
between two blocks was determined by the `slot_duration` of the
parachain. This PR introduces a more flexible model, where we try to
author multiple blocks in a single slot if the runtime allows it.

The block authoring loop is largely the same. The
[`SlotTimer`](https://github.com/paritytech/polkadot-sdk/blob/f1935bd9/cumulus/cli...

Follow up of : #7217, #7529 

When the zombienet tests were integrated into github, it seems like the
gitlab ones remained active. But they look a lot more unstable. This
causes confusion when the same tests fail and pass at the same time
(aside from extra costs). This PR attempts to get rid of the gitlab
ones.

As proposed by Gui :)

Closes #6851 

This PR adds an `EventEmitter` trait to the XCM Executor configuration,
enabling event emission for XCM handling. The implementation introduces
three dedicated functions to emit relevant events:

- `emit_sent_event`: Emits a `Sent` event when an XCM is successfully
sent.
- `emit_send_failure_event`: Emits a `SendFailed` event when an XCM
fails to send.
- `emit_process_failure_event`: Emits a `ProcessXcmError` event when an
XCM fails during processing.

Allow using the legacy data field for GenericTransaction

#### PR Description

This pull request introduces measures to handle finality stalls by :
- notifying outdated transactions with a
[`FinalityTimeout`](https://github.com/paritytech/polkadot-sdk/blob/d821c84d/substrate/client/transaction-pool/api/src/lib.rs#L145-L147)
event.
- removing outdated views from the `view_store`

An item is considered _outdated_ when the difference between its
associated block and the current block exceeds a pre-defined threshold.

#### Note for Reviewers
The core logic is provided in the following small commits:
- `ViewStore`: new method
[`finality_stall_view_cleanup`](https://github.com/paritytech/polkadot-sdk/blob/d821c84d/substrate/client/transaction-pool/src/fork_aware_txpool/view_store.rs#L869-L903)
for removing stale views was added: 64267000
- `ForkAwareTransactionPool`: core logic for tracking finality stalls
added here: 7b37ea6f. Entry point in
[`finality_stall_cleanup`](https://github.com/paritytech/polkadot-sdk/blob/d821c84d/substrate/client/transaction-pool/src/fork_aware_txpool/fork_aware_txpool.rs#L1096-L1136)
- Some related renaming was made to better reflect purpose/shorten the
names: 1a3a1284, a511601f. Also new method
[`transactions_finality_timeout`](https://github.com/paritytech/polkadot-sdk/blob/a511601f/substrate/client/transaction-pool/src/fork_aware_txpool/multi_view_listener.rs#L771-L790)
for triggering external events was added for `MultiViewListener`.
- `included_transactions` which basically is mapping `block hash ->
included transactions hashes`, is also used to find to included
transactions.

I also sneaked in some minor improvements:
- fixed per-transaction logging: 1572f721
- `handle_pre_finalized` method was removed, it was some old leftover
which is no longer needed: a6f84ad0

# Description

Builds up towards addressing #5497 by creating some zombienet-sdk code
infra that can be used to spin regular networks, as described in the
fork aware transaction pool testing setup added here #7100. It will be
used for developing tests against such networks, and to also spawn them
on demand locally through tooling that will be developed in follow ups.

## Integration

Node/runtime developers can run tests based on the zombienet-sdk infra
that spins frequently used networks which can be used for analyzing
behavior of various node related components, like fork aware transaction
pool.

## Review Notes

- Uses ttxt API implemented here:
https://github.com/michalkucharczyk/tx-test-tool/pull/22/files
- currently, only two test scenarios are considered: 10k future & 10k
ready txs are sent to two separate networks - one parachain and one
relaychain, asserting at the end on the finalization of all 20k txs on
both networks.

# Description

* This PR adds a new extrinsic `poke_deposit` to `pallet-proxy`. This
extrinsic will be used to re-adjust the deposits made in the pallet to
create a proxy or to create an announcement.
* Part of #5591 

## Review Notes

* Added a new extrinsic `poke_deposit` in `pallet-proxy`.
* This extrinsic checks and adjusts the deposits made for either
creating a proxy or creating an announcement or both.
* Added a new event `DepositPoked` to be emitted upon a successful call
of the extrinsic.
* Although the immediate use of the extrinsic will be to give back some
of the deposit after the AH-migration, the extrinsic is written such
that it can work if the deposit decreases or increases (both).
* The call to the extrinsic would be `free` if an actual adjustment is
made to the deposit for creating a proxy or to the deposit for creating
an announcement or both and `paid` otherwise (when no deposit is
changed).
* Added a new enum `DepositKind` to differen...

[XCM] Add generic location to account converter that also works with external ecosystems for bridge hubs (#7809)

That's the continuation of
[PR#7313](https://github.com/paritytech/polkadot-sdk/pull/7313)

I discovered in https://github.com/paritytech/polkadot-sdk/pull/7459,
that the overhead benchmark is not working for glutton-westend, as the
client can't send `system.remark` extrinsics. This was due to 2 issues:

1. Alice was not set as sudo. Hence, the `CheckOnlySudoAccount` deemed
the extrinsic as invalid.
2. The `CheckNonce` TxExtension also marked the extrinsic as invalid, as
the account doesn't exist (because glutton has no balances pallet).

This PR fixes the 1.) for now. I wanted to simply remove the
`CheckNonce` in the TxExtension to fix 2., but it turns out that this is
not possible, as the tx-pool needs the nonce tag to identify the
transaction. https://github.com/paritytech/polkadot-sdk/pull/6884 will
fix sending extrinsics on glutton.

the switch to the direct use of `gh` to upload artefacts to the release

This pr adds renaming before the upload so that displayed name of the

This PR enhances **`test_log_capture`**, ensuring logs are **captured
for assertions** and **printed to the console** during test execution.

## **Motivation**  

- Partially addresses #6119 and #6125, to improves developer **tracing
and debugging** in XCM-related tests.
- Builds on #7594, improving **log visibility** while maintaining test
**log capture capabilities**.
- While writing tests for #7234, I noticed this function was missing.
This PR adds it to streamline log handling in unit tests.

## **Changes**  

- Ensures logs up to `TRACE` level are **captured** (for assertions) and
**printed** (for visibility).
- Refines documentation to clearly specify **when to use** each
function.
- **Removes ANSI escape codes** from captured logs to ensure clean,
readable assertions.

## **When to Use?**  

| Usage | Captures Logs? | Prints Logs? | Example |

|----------------------------------------------|-----------------|--------------|-----------------------------------------------|
| `init_log_capture(LevelFilter::INFO, false)` |  Yes |  No | Capture
logs for assertions without printing. |
| `init_log_capture(LevelFilter::TRACE, true)` |  Yes |  Yes | Capture
logs and print them in test output. |
| `sp_tracing::init_for_tests()` |  No | 

 Yes | Print logs to the
console without capturing. |
