 **Core value:** Network traffic patterns are instantly recognizable as distinct sounds — a ping sounds different from HTTPS noise, which sounds different from a port scan.

 ## Accumulated Context
 
 ### Decisions
 
-Decisions are logged in PROJECT.md Key Decisions table.
-Recent decisions affecting current work:
-
-- Use `github.com/gopacket/gopacket` v1.5.0 (community fork) — NOT `google/gopacket` which is unmaintained
-- Use `github.com/packetcap/go-pcap` for live capture (pure Go, no CGo for capture layer)
-- Use `github.com/sjzar/go-lame` v0.0.9 for MP3 encoding (embeds LAME C source, CGo required at build time only)
-- Audio synthesis: hand-rolled additive sine oscillators + EMA amplitude smoothing (no external audio library)
-- Frequency table: register-separated harmonics (low drones = bulk traffic, mid = control, high = interactive)
-- [Phase 01]: Go installed to /home/dev/tools/go-install/go (no sudo); PATH export required each session
-- [Phase 01]: Classifier uses ordered []Rule slice with first-match-wins; no switch statement (D-02)
-- [Phase 01]: ICMP checked before TCP/UDP in Classify to handle packets with no port info
-- [Phase 01]: DefaultWindowMs=500: 500ms windows balance temporal resolution against snapshot frequency for audio synthesis
-- [Phase 01]: io.Writer injection in PrintSummary/PrintWindowLine enables test capture via bytes.Buffer and production use via os.Stderr
-- [Phase 01-capture-and-classification]: Use net.Interfaces() for listing (go-pcap has no FindAllDevs equivalent); privileges not required for enumeration
-- [Phase 01-capture-and-classification]: StartCapture uses 512-buffered channel with atomic drop counter to prevent backpressure blocking capture goroutine
-- [Phase 01-capture-and-classification]: Dynamic link type detection via handle.LinkType() not hardcoded LinkTypeEthernet
-- [Phase 01-04]: Cobra RunE + signal.NotifyContext for clean shutdown: context cancellation is the single stop signal propagating through all three pipeline stages
-- [Phase 01-04]: Three-stage pipeline: capture -> classify goroutine -> aggregate via buffered channels; 1024-buffered classified channel absorbs burst processing
-- [Phase 02]: go-lame v0.0.9 used for MP3 encoding (embedded LAME C source, no system library needed)
-- [Phase 02]: go-audio/wav excluded — writing PCM bytes directly to LameWriter is simpler (per Claude's Discretion grant in CONTEXT.md)
-- [Phase 02]: GainPerLayer applied in bank.go during mixing to ensure 11 max layers sum to 1.0 (D-10)
-- [Phase 02]: int16 conversion uses float * 32767 to avoid positive overflow at exactly +1.0
-- [Phase 02]: RunSynthesis takes snapshot slice (not channel) enabling zero-packet guard before file creation
-- [Phase 02]: EncodeMP3 and RunSynthesis are separate functions for independent testability
-- [Phase 03-01]: hashBucket uses (dstPort*31 + protoNum*7) % 4 for deterministic 4-bucket unknown class assignment
-- [Phase 03-01]: TestHashBucketDistribution uses minimal custom rules (not DefaultRules) because DefaultRules catch-all OtherTCP/OtherUDP prevent hashBucket from being reached
-- [Phase 03-02]: PrintSummary called before RunSynthesis per D-08 — user sees traffic stats before waiting for encoding to complete
-- [Phase 03-02]: Audio duration computed from snapshot count * DefaultWindowMs (not wall-clock) to avoid truncation for short captures
-- [Phase 04-power-user-features]: OpenCapture/StartCapture accept filter string; empty = no filter (backward compatible with live mode)
-- [Phase 04-power-user-features]: AggregatePcap: synchronous drain of events channel then assign to windows by Timestamp offset; gap windows pre-initialized with empty maps
-- [Phase 04-02]: bpfFilter and readPath are package-level globals for Cobra flag binding (same pattern as other flags)
-- [Phase 04-02]: runPcapMode checks for empty snapshots after PrintSummary so user sees zero-count table before error
-- [Phase 04-02]: deriveOutputPath uses filepath.Ext (last extension only) matching tcpdump convention

 ### Pending Todos
 
-None yet.
+None.
 
 ### Blockers/Concerns
 
-- Phase 2: Frequency mapping requires subjective listening validation — specific Hz values not determined by research; must test during Phase 2
-- Phase 3: Auto-clustering algorithm choice (hash-bucketing vs k-means) deferred until synthesis engine exists to evaluate perceptual results
-- macOS privilege model (BPF device vs CAP_NET_RAW) not verified by research — flag if macOS is a target during Phase 1
+None — all v1.0 blockers resolved.
