Remove unused epochguard.h

This commit simply deletes an unused header file, epochguard.h, from the Bitcoin Core source code. The file provided a helper class for tracking graph traversal 'epochs' in the memory pool, but nothing in the codebase was using it anymore.…

Rework CTxMemPool::GetChildren() to not use epochs

This commit is a small internal cleanup in Bitcoin Core's memory pool (mempool) code. It replaces a fast but complex deduplication trick ('epochs') with a simpler, slightly slower approach using sorting. The change saves 8 bytes per mempoo…

Rename weight -> clusterweight in RPC output, and add doc explaining mempool terminology

This commit renames a single field in a Bitcoin Core RPC output from 'weight' to 'clusterweight' and adds documentation explaining mempool fee/size terminology. It is a user-facing clarity/documentation change with no security-relevant cod…

Improve comments for getTransactionAncestry to reference cluster counts instead of descendants

This commit only changes two comment lines in a header file. It renames 'descendants' to 'cluster_count' in documentation to match what the code actually calculates. No executable code, logic, or behavior was changed, so there is no securi…

Fix comment to reference cluster limits, not chain limits

This commit changes a single word in a code comment, replacing 'chain' with 'cluster count' to accurately describe what the following code checks. It does not alter any program logic, behavior, or security properties.

Require mempool lock to be held when invoking TRUC checks

This commit changes two Bitcoin Core functions that enforce special rules for a new type of transaction called TRUC. Previously, one function locked the memory pool (mempool) itself. Now both functions require their callers to already hold…

Sanity check feerate diagram in CTxMemPool::check()

This commit adds extra internal consistency checks to Bitcoin Core's memory pool validation routine and turns some soft 'Assume' warnings into hard 'assert' failures. It does not change network rules or how transactions are accepted; it on…

Fix parameter name in getmempoolcluster rpc

This is a one-word documentation fix in a Bitcoin Core RPC help message. The error message shown when a user provides an invalid transaction ID now says 'txid' instead of 'parameter 1'. There is no security impact.

rpc: improve getmempoolcluster output

This commit changes the format of a Bitcoin Core RPC command called getmempoolcluster so it groups transactions into 'chunks' rather than listing each transaction separately. It also adds a clearer error message when the requested transact…

Avoid using mapTx.modify() to update modified fees

This is a small internal cleanup in Bitcoin Core's memory pool (mempool) code. It changes how transaction fee adjustments are updated, removing an unnecessary wrapper and making a fee field directly mutable. There is no indication this fix…

No security-relevant signal: change is a refactoring/simplificationMutable fee field could theoretically affect mempool eviction/mining priority logic if misused, but the diff does not introduce such misuseNo bounds/safety change: SaturatingAdd remains in place

doc: add release notes snippet for cluster mempool

This commit only adds a release notes document describing a previously implemented mempool redesign called 'cluster mempool.' It contains no code changes, no bug fixes, and no security-related disclosures. It is purely documentation.
