#13045: sc-rpc-server: bound the cardinality of the RPC metrics method label

The substrate_rpc_calls_* metrics used the requested method name as the method label without restricting it to registered methods, so the label could take an unbounded number of values. The label is now bounded to the registered method set; any other name is recorded as unknown, keeping the series count finite.

RpcMetrics::with_known_methods sets the allowlist and the RPC server wires it at start; a metrics instance without it keeps the previous behaviour.

XCM

🛠️ Runtime Dev

💥 #12378: pallet-assets: allow force_create to set an arbitrary asset id when auto-increment is enabled

force_create no longer requires the asset id to equal NextAssetId: a ForceOrigin may create an asset with any id not currently in use, and the id is then marked as allocated so it can never later collide. Asset id allocation is now configured explicitly via the new Config::AssetIdAllocator (AutoIncAssetId for auto-incrementing ids, () for none), replacing the implicit NextAssetId-is-Some plus AutoIncAssetId callback mechanism. Only the force_create call is relaxed; fungibles::Create::create is not gated on ForceOrigin and still requires the id the allocator dictates. …

[#12106]: sp-database: aggregate same-key refcount ops within a transaction

Fix a kvdb refcount-leak in sp_database: when one Transaction contains multiple Store/Reference/Release ops on the same key, each op reads a stale on-disk counter and writes back to the same counter key — the underlying DBTransaction keeps only the last put, collapsing N ops to a single ±1. commit_impl now replays per-(col, key) refcount ops in transaction order against one on-disk counter read, then emits one final write per unique key.

[#12388]: collator-protocol revamp: Send RC PeerId with ApprovedPeer UMP signal

Currently the collator sends its parachain PeerId within the ApprovedPeer UMP signal, which is wrong because this peer id is not known on the relay chain.
As a result on CandidateIncluded event the score is bumped for the wrong PeerId and the collator remains with zero reputation no matter its honest work.

[#12409]: Add increase_value call to pallet-multi-asset-bounties

Adds a curator-gated increase_value(parent_bounty_id, amount) extrinsic that raises an active bounty's recorded value by amount.

Bounty payouts are bounded by the recorded value, not the account balance, so funds transferred into a bounty account out-of-band (e.g. recurring external top-ups) are otherwise unspendable. This call lets the curator register those funds without a
governance round.

Behaviour:

• Only the curator of an Active bounty may call it; the value is increase-only.
• The curator deposit is re-evaluated and any additional hold is collected for the new value.
• Emits BountyValueIncreased { index, old_value, new_value }.
• Parent bounties only.

This is an additive change (new call and event variant); there is no storage migration.

[#12534]: pallet-utility: fix dispatch class of empty batch/batch_all/force_batch

Utility::batch, Utility::batch_all and Utility::force_batch derive their DispatchClass by folding over the dispatch classes of the wrapped calls, starting from an Operational accumulator so that the batch is only Operational if every wrapped call is Operational. When called with an empty list of calls, the fold had nothing to iterate over and returned the initial Operational value unchanged, making empty batches incorrectly Operational instead of Normal. Empty batches now explicitly resolve to DispatchClass::Normal.

[#12080]: fix(statement-network): split peer metric by kind

Impl #12060

Summary

• Change substrate_sync_statement_peers_connected from a plain gauge to a GaugeVec labelled by kind
• Report statement protocol peers as kind="full" or kind="light"

[#11415]: Statement store e2e integration tests lite person setup

Summary

• Add a lite person registration test that exercises the full PeopleLite::attest flow on a live parachain, including ring-VRF key generation, attestation, and subsequent statement submission.

[#10477]: Block Bundling Node Side

Implements the node-side logic for block bundling (aka 500ms blocks) in parachains.
The main changes are in the slot-based collator: instead of building one block per core, blocks are built as requested and distributed over the available cores.

[#11701]: statement-store: Test flooding detection

Fixed a bug with double peer state cleanup. Added two zombienet integration tests that verify statement-store flooding detection

[#11107]: Add runtime metadata detection for Aura authority ID

Adds optional runtime metadata-based detection for Aura authority ID types in polkadot-omni-node-lib.

When metadata is available, the node detects whether Aura uses sr25519 or ed25519 directly from the runtime. If detection fails or metadata is unavailable, it falls back to chain spec ID heuristics.

A warning is emitted when the Aura authority ID type is not found in metadata.

[#11685]: Pass NodeExtraArgs through Dev Chain

Enables the statement store when running polkadot-omni-node in dev mode with --enable-statement-store.

The dev Aura node path now wires the statement store the same way as the regular node path: it registers the statement network protocol, builds the store, exposes the RPCs, and passes the statement store extension into offchain workers.

Also wires up the storage monitor in dev mode and emits warnings when collation-specific flags (--authoring-policy, --export-pov, --max-pov-percentage) are passed in dev mode where they have no effect.

NodeExtraArgs is now destructured in start_dev_node so the compiler will enforce that any newly added fields are explicitly handled.

[#12038]: Network: Add bitswap client

Adds a Bitswap client API to sc-network for fetching CID-addressed blocks from a peer over the native litep2p Bitswap protocol. The public API is block-fetch only and reports per-CID outcomes as either delivered bytes or "missing"; on-wire presence (HAVE / DONT_HAVE) is handled internally and is not part of the public surface.

[#11387]: docs/async_back: Align docs to latest behavior

Tiny PR to update the async backing documentation / guidelines:

• older params are no longer used async_backing_params
• UNINCLUDED_SEGMENT_CAPACITY is now 3
• no need for experimental feature flags

Closes: #8804

[#12207]: statement-store: remove unused Proof::OnChain variant

Removes the Proof::OnChain variant from sp_statement_store::Proof because it was unused.

[#12113]: Aura: Fetch slot duration at parent and not best block

Fetch the slot duration from the parent we are building on top of and not from the best block.

[#11967]: Experimental collator protocol — leaf-authoritative capacity tracking

Reworks the experimental collator protocol's validator side around a leaf-authoritative capacity model. The leaf's per-core claim queue is the single source of truth; capacity at every scheduling parent (SP) on a path to that leaf is derived via offset arithmetic.

Behavior changes vs. master:

• Rotation-boundary bug fixed. After a group rotation, candidates for both the pre-rotation core's para (advertised at the pre-rotation leaf) and the post-rotation core's para (at the post-rotation leaf) are accepted. Previously, rotation caused claim-queue state for the old core to be overwritten and ancestor-rooted advertisements to be wrongly rejected.

• Fork-aware view cleanup. When a leaf is dropped, SPs are removed from per_scheduling_parent (with their in-flight fetches cancelled) only when no remaining leaf still references them. Previously, sibling-fork retention in implicit-view storage could leave SPs orphaned with leaked in-flight fetches.

• Free-slot accounting tightened to the current leaf. Assignments and free CQ positions now reflect only what the current leaf's CQ actually predicts. Previously, claim-queue state for already-produced ancestor blocks lingered until those blocks were pruned, so paras and slots that had already been backed on-chain were still reported as open — keeping peers connected past their relevance and offering capacity for slots that could no longer be filled.

Internals: the previous ClaimQueueState / PerLeafClaimQueueState machinery is gone (~2200 LoC deleted). Capacity is now computed per-(leaf, core) by build_leaf_core_cqs as a Vec<LeafCoreCq>, where each LeafCoreCq holds the leaf's CQ as
Vec<Option<ParaId>> (consumed positions cleared to None) and an sps_by_depth: Vec<Option<Hash>> masking cross-core ancestors. The fetch planner walks free CQ positions back-to-front and picks the best advertisement among same-core SPs whose
window reaches that position.

Test coverage in validator_side_experimental/tests.rs:

• core_rotation_accepts_candidates_for_both_cores — regression for the original rotation-boundary bug.
• Five active-fork tests covering: assignment union across leaves, longest-window capacity at a common ancestor across different-length forks, no double-counting of in-flight candidates across sibling forks, and reclamation of capacity / peer disconnection when a
  fork is dropped.
• Two linear multi-SP tests pinning over-fetch and under-fetch invariants when ancestor and leaf SPs share the same per-core CQ.
• Tests for cross-SP reputation arbitration and cross-core slot-reservation correctness.
• Three previously-existing tests rewritten to assert the same intent against the new model.

No public API changes; behavior change is contained to the experimental validator side.

[#11922]: Update merkle mountain lib

Updates the merkle mountain crate to its latest version.

[#11616]: Move era reward minting from staking to DAP

Introduces dual-mode era rewards in pallet-staking-async, controlled by Config::DisableMinting:

• true (non-minting): staking expects an external source to fund a general reward pot. At era boundary, the balance is snapshotted into an era-specific pot. Payouts transfer from the pot. Unclaimed rewards returned via UnclaimedRewardHandler.
• false (legacy minting): EraPayout computes inflation, tokens minted on payout, remainder sent to RewardRemainder. Kept for Kusama compatibility.

Switching from legacy to non-minting is irreversible.

New config: DisableMinting, UnclaimedRewardHandler, GeneralPots, EraPots, StakerRewardCalculator. New storage: MaxCommission, DisableMintingGuard.
New extrinsic: set_max_commission.

Runtimes using non-minting mode provide an IssuanceCurve impl to DAP and register StakerRewardRecipient as a budget recipient. DAP storage version bumped to V2 with migration.

[#12225]: pallet-revive: map account in prepare_dry_run

Summary

• Map the origin account in prepare_dry_run when it is not already mapped, so dry-running contract calls/instantiations does not fail with AccountUnmapped for callers that never registered a mapping.

[#12115]: pallet-revive: recalibrate contains_storage benchmark

The contains_storage benchmark now exercises the persistent storage path, matching how WeightInfo::contains_storage is dispatched from the precompile. The transient path remains benchmarked separately as seal_contains_transient_storage.
Also the clear_storage, contains_storage, take_storage and the transient clear/contains benchmarks now size their pre-existing value by n.

[#11770]: Fix PSM migration to run on first deployment

Replaces the versioned MigrateToV1 with an idempotent InitializePsm migration.

The previous MigrateToV1 used VersionedMigration<0, 1> which never ran on fresh deployments because BeforeAllRuntimeMigrations initializes the on-chain storage version to the in-code version (1) before migrations execute, causing the version check to skip.

InitializePsm instead checks whether each external asset already exists and skips it if so. This makes it safe to run multiple times with no storage version dependency.
