Summary

After a chain prune (reorg), handlePrunedBlocks() moves mined transactions back to pending, which can temporarily push the v2 pool over its configured size limit. The EvictionManager already dispatches a CHAIN_PRUNED event (via evictAfterChainPrune()), but LowPriorityEvictionRule only handled TXS_ADDED events — returning an empty result for CHAIN_PRUNED and leaving the pool over its limit until the next addPendingTxs() call.

  • Extended LowPriorityEvictionRule.evict() to also trigger on CHAIN_PRUNED events, so the pool size limit is enforced immediately after a reorg
  • Guarded context.newTxHashes access (only present on the TXS_ADDED variant of the discriminated union) with an event-type check, logging a distinct message for the chain-prune case
  • Added unit tests for CHAIN_PRUNED handling in LowPriorityEvictionRule (eviction when over limit, no-op when under limit, no-op when disabled, error handling)
  • Added integration tests in tx_pool_v2.test.ts exercising the full add → mine → set limit → prune → verify eviction flow

Test plan

  • Unit tests pass: yarn workspace @aztec/p2p test src/mem_pools/tx_pool_v2/eviction/low_priority_eviction_rule.test.ts (14 tests)
  • Integration tests pass: yarn workspace @aztec/p2p test src/mem_pools/tx_pool_v2/tx_pool_v2.test.ts -t 'handlePrunedBlocks' (12 tests)
  • Lint and format pass

Fixes A-560

## Summary

After a chain prune (reorg), `handlePrunedBlocks()` moves mined transactions back to pending, which can temporarily push the v2 pool over its configured size limit. The `EvictionManager` already dispatches a `CHAIN_PRUNED` event (via `evictAfterChainPrune()`), but `LowPriorityEvictionRule` only handled `TXS_ADDED` events — returning an empty result for `CHAIN_PRUNED` and leaving the pool over its limit until the next `addPendingTxs()` call.

- Extended `LowPriorityEvictionRule.evict()` to also trigger on `CHAIN_PRUNED` events, so the pool size limit is enforced immediately after a reorg
- Guarded `context.newTxHashes` access (only present on the `TXS_ADDED` variant of the discriminated union) with an event-type check, logging a distinct message for the chain-prune case
- Added unit tests for `CHAIN_PRUNED` handling in `LowPriorityEvictionRule` (eviction when over limit, no-op when under limit, no-op when disabled, error handling)
- Added integration tests in `tx_pool_v2.test.ts` exercising the full add → mine → set limit → prune → verify eviction flow

## Test plan

- [x] Unit tests pass: `yarn workspace @aztec/p2p test src/mem_pools/tx_pool_v2/eviction/low_priority_eviction_rule.test.ts` (14 tests)
- [x] Integration tests pass: `yarn workspace @aztec/p2p test src/mem_pools/tx_pool_v2/tx_pool_v2.test.ts -t 'handlePrunedBlocks'` (12 tests)
- [x] Lint and format pass

Fixes A-560
