When an analysis is stopped and restarted, the previous run's
gadget_errors and has_gadget_warnings were persisted in output_config
and never cleared, causing a false "Some gadgets failed to start"
warning in the UI even when all gadgets started successfully.

Upgrade script now interactively prompts for namespace, target version,
registry, memory limit, and buffer length with validation at each step.
Also includes pending fixes: sync gRPC method, migration dollar-quoting,
and double-v prefix in gadget version display.
Made-with: Cursor
- Reduce Inspektor Gadget memory limit from 12Gi to 6Gi with buffer optimization (16384->8192)
- Add InspektorGadgetHighMemory (>3Gi) and CriticalMemory (>5Gi) Prometheus alerts
- Add configurable event ingestion rate limiting via Settings UI (ingestion_rate_limit_per_second)
- Update /analysis-limits/defaults endpoint to read from DB with Pydantic fallback
- Orchestrator fetches rate limit via isolated HTTP call (avoids cross-thread async issues)
- Ingestion service uses session-based rate limit with >0 comparison (fixes or-operator semantic bug)
- Add gadget_version (field 22) and max_events_per_second (field 23) to protobuf StartCollectionRequest
- Sync backend/proto with proto/ (add GadgetError message to backend copy)
- Upgrade Inspektor Gadget from v0.48.0 to v0.50.1 across all references
- Dynamic OCI image tagging: cluster-specific gadget_version flows through gRPC to ingestion service
- Fix get_cluster_sync SQL to include gadget_version column
- Fix NULL gadget_version causing protobuf TypeError (row[10] or '' pattern)
- Add GET /clusters/{id}/gadget-upgrade-script endpoint with cluster-specific parameters
- Add GadgetUpgradeModal and semver-based upgrade badge to Cluster Management page
- Add upgrade available indicator to Dashboard OperationsTab
- Include supported_gadget_version in GET /clusters response
- Update cluster_validator minimum supported version from v0.18 to v0.46.0
- Add ingestion_rate_limit_per_second to migration seed data and auto_stop_monitor fallback
- Improve AnalysisWizard Rolling Window and Recurring mode descriptions
- Add GADGET_SUPPORTED_VERSION and GADGET_MIN_SUPPORTED_VERSION to backend config
- Fix hardcoded "1.0.0" version in backend root/info endpoints to use __full_version__
- Replace grep -oP with POSIX grep -oE in upgrade script (macOS compatibility)
- Add ConfigMap events-buffer-length optimization step to upgrade script
- Add GADGET_VERSION sed substitution to prepare-manifests.sh
- Bump Flowfish version from 2.4.0 to 2.5.0
- Update pipeline GADGET_VERSION variable and all documentation references

Replace client-side event bucketing (limited to 50 paginated events) with
server-side ClickHouse aggregation using toStartOfInterval(). This fixes
the timeline showing a single bar despite multiple analysis runs.
Backend:
- Add query_event_histogram() to timeseries-query with epoch-aligned
bucket generation, capability_checks security filter, and count()-based
empty table detection
- Add GET /events/histogram endpoints through all layers (timeseries-query,
backend repository, service, router with analysis_id validation)
Frontend:
- Add getEventHistogram RTK Query hook with EventHistogram cache tag
- Replace client-side timelineData bucketing with server-side histogram
- Stacked bar colors (sorted by eventTypeConfig order for consistency)
- Clickable bars for time-range filtering (zoom-in)
- Loading skeleton, smart time labels (DD MMM HH:mm for multi-day),
full event type legend filtered by presence, total event count in header
- event_types filter synced with histogram query
Documentation:
- Update CURRENT_ARCHITECTURE, DATA_SOURCES, ARCHITECTURE_DETAILED,
services/README, and OpenAPI spec with /events/histogram endpoint

Kubernetes DNS search domain expansion creates multiple NXDOMAIN queries
for the same external domain (e.g. auth.docker.io.cluster.local,
auth.docker.io.svc.cluster.local). Without normalization, each variant
becomes a separate Neo4j node, inflating Public connections on the Map.
Backend (graph-writer):
- Rewrite _normalize_dns_name with TLD-safe 4-step algorithm
- Strip .svc.cluster.local, .<ns>.svc.cluster.local, .cluster.local
- Support custom search domains via DNS_SEARCH_DOMAINS env var
- Apply normalization in process_dns_query and process_sni_event
- Fix NXDOMAIN vertex overriding NOERROR resolved IP data
- Add KNOWN_TLDS/MULTI_LEVEL_TLDS for .com.tr/.co.uk safety checks
Frontend (NetworkExplorer):
- Add "Hide Search Domain Artifacts" toggle on DNS Queries tab
- Detect NXDOMAIN entries ending with .cluster.local
- Show artifact count, toggle hidden by default
Raw ClickHouse data and API responses are NOT modified — only the
dependency graph (Neo4j) is deduplicated. Full debugging data preserved.
Tests: 31 cases covering normalization, edge cases, and integration.

Restructure /dependencies/summary response to provide per-service
downstream/callers breakdowns instead of a single aggregated view.
Backend:
- Unified loop in format_dependency_summary handles single and multi-service
identically, fixing replica data loss bug for single-service queries
- Each matched_service now carries its own downstream/callers DependencySummaryGroup
- New top-level summary object with globally deduplicated aggregate counts
(split downstream_critical_count and callers_critical_count)
- hop_count added to _compact_service (only when > 1 to avoid depth=1 noise)
- _dedup_entries now preserves entry with lowest hop_count on collision
- multi_service flag now correctly checks collapsed workload count
Frontend:
- Updated TypeScript interfaces (DependencySummary, MatchedService with groups)
- IntegrationHub Preview: per-service Collapse for multi-service, summary stats
- DependencyCategoryGroup: conditional hop_count column for multi-depth queries
- Snippet builders updated to parse matched_services and summary structure
API & Docs:
- OpenAPI spec: new DependencySummary schema, depth parameter descriptions
- README, feature-list, DATA_ARCHITECTURE docs updated
- Fixed pre-existing doc bug (default traversal depth 3 -> 1)
