In `@client/internal/netflow/store/memory.go`:
- Around line 81-132: In GetAggregatedEvents, the aggregation lookup key is
built with the ICMP code (aggregationKey.icmpType = v.ICMPCode) which groups by
the wrong field; change the lookupKey construction in GetAggregatedEvents to use
the ICMP Type field from the event (e.g., v.ICMPType) so aggregation groups by
type not code, and ensure aggregationKey.icmpType's expected type matches the
event field; update any related comments if present.

In `@flow/proto/generate.sh`:
- Around line 15-16: Uncomment and restore the pinned go install lines in
generate.sh for the protobuf generators so regeneration is reproducible:
re-enable the go install invocations for protoc-gen-go and protoc-gen-go-grpc
(the previously commented lines) and update their version tags to match the
repository's checked-in generators (protoc-gen-go v1.36.11 and
protoc-gen-go-grpc v1.6.1); leave any protoc binary handling unchanged but
ensure the script documents the required protoc version (protoc v7.34.1) if it
cannot be installed via go.

In `@client/internal/netflow/manager.go`:
- Around line 298-318: The FlowFields protobuf is missing the aggregated
counters, so populate FlowFields.NumOfStarts, FlowFields.NumOfEnds, and
FlowFields.NumOfDrops from the nftypes.Event before returning the
proto.FlowEvent: in toProtoEvent(publicKey []byte, event *nftypes.Event) add the
three fields (NumOfStarts: event.NumOfStarts, NumOfEnds: event.NumOfEnds,
NumOfDrops: event.NumOfDrops) inside the proto.FlowFields literal so aggregated
counts computed by GetAggregatedEvents() are sent to the server.

Nitpick comments:
In `@client/internal/netflow/store/memory.go`:
- Around line 73-79: The struct field aggregationKey.icmpType is misnamed
because callers populate it with v.ICMPCode; rename the field to icmpCode to
match usage and improve clarity. Update the aggregationKey definition (replace
icmpType with icmpCode) and any references to aggregationKey.icmpType throughout
the codebase (e.g., places that assign v.ICMPCode) so they compile and keep
semantics unchanged.
- Around line 123-127: Add a short explanatory comment above the timestamp
selection block explaining that the condition
aggregatedEvent.Timestamp.Compare(v.Timestamp) > 0 intentionally preserves the
earliest event's timestamp, ID and Type when merging events so the aggregated
record represents the start of the aggregation window; reference the variables
aggregatedEvent, v, Timestamp.Compare, ID and Type in the comment so future
readers understand the preserved metadata semantic.

In `@client/internal/netflow/store/tcp_aggregation_test.go`:
- Around line 21-279: Add an ICMP test case to TestTcpAggregation to cover the
ICMP-specific aggregation key (ICMPCode) used by GetAggregatedEvents: create
events with Protocol types.ICMP and matching ICMPType/ICMPCode (e.g., echo
request ICMPType=8, ICMPCode=0) with start and end events that have
RxBytes/TXBytes to be summed, store them via
NewAggregatingMemoryStore().StoreEvent, then include an expected aggregated
Event that verifies RxBytes/TXBytes are summed and NumOfStarts/NumOfEnds reflect
the inputs; reference TestTcpAggregation, GetAggregatedEvents,
NewAggregatingMemoryStore, and the ICMPCode/ICMPType fields when adding the
case.

In `@client/internal/netflow/store/event_aggregation_test.go`:
- Around line 45-47: The generateEvents function is being called inside a loop
with randomized DestPort values that can collide, causing test nondeterminism
when multiple event groups accidentally get the same port and merge. Modify the
generateEvents calls to use deterministic port values derived from the loop
variable i (such as basePort + i or similar) instead of relying on
randomization. This applies at both the loop starting at line 45-47 and the
similar aggregation test loop at lines 110-118 to ensure each generated event
group has a unique, collision-free port identifier.

In `@shared/management/http/api/openapi.yml`:
- Around line 2768-2779: The OpenAPI schema exposes three new counter fields
(num_of_starts, num_of_ends, num_of_drops) but the toProtoEvent function does
not map these counters to the corresponding proto fields
(FlowFields.NumOfStarts, FlowFields.NumOfEnds, FlowFields.NumOfDrops). Update
the toProtoEvent function to set these three FlowFields proto properties from
the aggregated counter values so the new API fields are properly populated
end-to-end.

Inline comments:
In `@client/internal/netflow/manager.go`:
- Line 254: The timer initialization at line 254 respects the configurable
m.retryInterval for the first attempt, but line 283 hard-codes a one-second
duration when resetting the timer in the retry loop. Replace the hard-coded
one-second interval at line 283 with m.retryInterval to ensure the configurable
retry interval is applied consistently across all retry attempts, not just the
initial one.
- Around line 251-253: The eventsWithoutAcks store in the Manager.startRetries
method is unbounded and grows indefinitely when ACKs stop arriving, consuming
unbounded client memory during receiver outages. Add a maximum size limit and
age-based eviction policy to the eventsWithoutAcks store to prevent unlimited
growth, implementing logic to drop the oldest events when the threshold is
reached. Apply this bounded store policy consistently across all event storage
and retry logic throughout the Manager implementation.

In `@client/internal/netflow/store/memory.go`:
- Around line 77-84: The aggregationKey struct is missing the sourcePort field,
which causes TCP/UDP events from the same source IP but different source ports
to be incorrectly aggregated together. Add a sourcePort field of type uint16 to
the aggregationKey struct (similar to the existing destPort field), then ensure
this field is properly populated when creating aggregation keys in the grouping
logic around line 93 and when building keys around lines 140-144, so that events
are only aggregated when they match on source IP, source port, destination
IP/port, direction, and protocol.
- Line 84: The unsupported-protocol handling branch returns before assigning
WindowStart, WindowEnd, and single-event counter values, causing toProtoEvent to
serialize zero values for these metadata fields. Additionally, the unique field
assignment uses time.Now().UnixNano() for uniqueness instead of the event ID.
Ensure that all unsupported/pass-through protocol events have proper
WindowStart, WindowEnd, and counter assignments before returning, and replace
the time.Now().UnixNano() call with the actual event ID when setting the unique
field to properly track event identity regardless of protocol type.
- Around line 69-72: Capture the current time once before creating the
AggregatingMemory object in the window rotation logic. Instead of calling
time.Now() twice (once for WindowEnd when creating the toret AggregatingMemory
and once for WindowStart when resetting am.WindowStart), assign time.Now() to a
variable like now, then use this same now variable for both the WindowEnd field
in the AggregatingMemory initialization and the am.WindowStart assignment. This
ensures consistent timestamp boundaries and eliminates any time gap between the
closing and opening of aggregation windows.
- Around line 112-118: The ICMPCode field is not included in the aggregation key
for ICMP events, but it is still serialized by toProtoEvent, which leaves an
arbitrary code value in the aggregated output. In the code section where
event.Type is set to types.TypeUnknown (around line 112), explicitly reset the
ICMPCode field to its zero value (0 or nil depending on the field type) to
ensure consistency with the type-level aggregation. This should be done
alongside the existing assignments to event.WindowStart and event.WindowEnd to
maintain data integrity.

Outside diff comments:
In `@client/internal/netflow/manager.go`:
- Around line 54-60: The eventsWithoutAcks store is not being cleared when the
flow is disabled or the receiver changes, which can cause stale event metadata
to be retried to a new receiver. Add logic to clear or reinitialize the
eventsWithoutAcks store in the disableFlow method (referenced at lines 94-100)
and in the receiver change/reset logic (referenced at lines 143-150) to ensure
that pending events are discarded when these lifecycle boundaries are crossed.

Nitpick comments:
In `@client/internal/netflow/store/event_aggregation_test.go`:
- Around line 57-58: Expand the test cases in the event aggregation test to
include boundary coverage for source ports and ICMP codes. Specifically, add
test scenarios where same-source and same-destination TCP or UDP events have
different source ports (by modifying the generateEvents calls) and add test
cases where ICMPCode is set on ICMP events. This ensures that aggregation keys
properly distinguish events based on these fields and prevents regressions where
fields still used downstream could be incorrectly collapsed during aggregation.
Apply these additions across all relevant test cases including the ones around
lines 57-58, 109-110, and 129-165.

- Line 157: The subtest name in the t.Run call is using
string(types.ProtocolUnknown) which produces a NUL-character string instead of a
readable label. Replace string(types.ProtocolUnknown) in the subtest name
concatenation with a proper readable string representation of the unknown
protocol type, such as a string constant or by calling an appropriate String()
method if available on the types.ProtocolUnknown value.
