gurix 1be56a5a35 feat(01-04): wire Cobra CLI with capture-classify-aggregate pipeline 
- cmd/netsynth/main.go: Cobra root command with -i, --list-interfaces, --verbose flags
- Signal handling via signal.NotifyContext for clean Ctrl+C shutdown
- 3-stage pipeline: capture.StartCapture -> classify.NewClassifier -> aggregate.Aggregate
- Permission errors surface platform-specific sudo/setcap hint (CAPT-04)
- --verbose flag wires aggregate.PrintWindowLine callback for per-window output
- Exit summary via aggregate.PrintSummary with dropped packet warning
- cmd/netsynth/main_test.go: 3 tests covering flag parsing and help output
- go.mod: cobra v1.10.2 and go-pcap promoted to direct dependencies

gurix 31564ba0f5 docs(01-03): complete aggregation and stats reporting plan 
- Add 01-03-SUMMARY.md with window aggregator and formatting outcomes
- Advance STATE.md plan counter to 3/4, update progress to 75%
- Record execution metrics: 8min, 2 tasks, 4 files

gurix f2bebaf554 feat(01-03): implement exit summary and verbose window output formatting 
- Add PrintSummary writing per-protocol packet counts with percentages and TOTAL to io.Writer
- Add PrintWindowLine writing single verbose window activity line in [window N] CLASS:count format
- Add AccumulateTotals merging WindowSnapshot counts into cumulative totals map
- Output sorted alphabetically for deterministic display
- Add 6 tests: PrintSummary, PrintSummaryEmpty, PrintSummarySorted, PrintWindowLine, PrintWindowLineEmpty, AccumulateTotals

gurix 9446dd5c27 feat(01-02): implement capture package with OpenCapture, ListInterfaces, StartCapture 
- ListInterfaces uses net.Interfaces() stdlib (no pcap dependency for listing)
- OpenCapture wraps packetcap/go-pcap with platform-specific permission error handling
- StartCapture uses buffered channel (512) with atomic drop counter
- Dynamic link type detection via layers.LinkType(handle.LinkType())
- Linux error shows setcap cap_net_raw+ep hint; macOS shows sudo hint
- Add github.com/packetcap/go-pcap v0.0.0-20251215 to go.mod
 2026-03-25 12:17:16 +01:00
gurix 2a8fd7dd05 feat(01-03): implement ticker-driven window aggregator with TDD 
- Add Aggregate function reading ClassifiedPackets, emitting WindowSnapshots per time window
- Add DefaultWindowMs=500 constant for configurable window duration
- Flush partial window on done channel close or closed events channel
- Call optional onSnapshot callback per window for verbose mode
- Add 5 tests: EmitsSnapshot, MultipleClasses, DoneFlushesPartial, EmptyWindow, WindowIndex

gurix 1eb1dd4104 test(01-02): add failing tests for capture package 
- TestListInterfaces: verifies net.Interfaces() returns at least 1 interface
- TestListInterfacesFormat: verifies interface Name is non-empty
- TestIsPermissionError: table-driven positive cases for perm error detection
- TestIsPermissionErrorNegative: non-perm errors not flagged
- TestPermissionErrorMsg: verifies sudo + interface name + Linux setcap hint

gurix df5fea717b docs(01-01): complete bootstrap and protocol classification plan 
- Add 01-01-SUMMARY.md documenting outcomes, commits, and decisions
- STATE.md: advance to plan 2/4, record metrics, add key decisions
- ROADMAP.md: update phase 1 progress (1/4 plans complete)
- REQUIREMENTS.md: mark CLAS-01 complete

gurix 25e0dc3ece chore(01-01): tidy go.mod after classifier implementation 
- go mod tidy updates go.mod to reflect actual imports
- gopacket is now a direct dependency (used in classifier.go)
- go-pcap and cobra remain in go.sum for future plans
 2026-03-25 12:13:01 +01:00
gurix 48ef6e53ad feat(01-01): implement config-driven classifier with 12 protocol rules 
- Add classify/rules.go: Rule struct and DefaultRules slice with 12 rules
  (10 specific protocol rules + 2 catch-alls for other-TCP/other-UDP)
- Add classify/classifier.go: Classifier with NewClassifier and Classify methods
- Config-driven slice (not switch) per D-02; first-match-wins ordering
- Returns ClassUnknown for non-TCP/UDP/ICMP traffic per D-03
- All 14 tests pass covering all 11 traffic classes
 2026-03-25 12:12:47 +01:00
gurix f233e80f4b test(01-01): add failing tests for all 11 protocol classification classes 
- Tests for ICMP, DNS/UDP, DNS/TCP, HTTPS, HTTP, SSH, SMTP, NTP, DHCP(67/68),
  other-TCP, other-UDP, unknown
- Test for order-dependent first-match-wins rule behavior
- Uses gopacket SerializeLayers to build synthetic packets

gurix 15e8143389 feat(01-01): install Go 1.24, initialize module, create shared types 
- Initialize Go module github.com/netsynth/netsynth with Go 1.24.1
- Create classify/types.go with 11 TrafficClass constants (ICMP, DNS, HTTPS,
  HTTP, SSH, SMTP, NTP, DHCP, other-TCP, other-UDP, unknown)
- Add ClassifiedPacket and WindowSnapshot shared types
- Add Phase 1 dependencies: gopacket v1.5.0, go-pcap, cobra v1.10.2
