 The product is moving from a capable public beta toward a repeatable, evidence-backed field instrument.
 
-## Release gate: v1.3.x beta
+## Completed foundation: v1.3.x beta
 
 - Deterministic selected-stream ownership without click-triggered refresh
 - Coherent waveform, RMS, and phasor snapshots
 - Verified 2/4/8-cycle timebases
 - Fast harmonic/shape change detection when raw payload changes
 - Multi-stream, rollover, malformed-frame, and publisher-restart regression coverage
-- Repository, CI, security, and release hardening
+- Repeated deterministic Runtime Stability workflow with downloadable TRX evidence
+- Maintained 60-minute Windows/Npcap field evidence
+- Repository, CI, security, candidate-package, and release hardening
 
-### v1.3.0-beta.2 stabilization
+## Current: v1.4 runtime architecture
 
-- Repeated deterministic Runtime Stability workflow with downloadable TRX evidence
-- Eight-stream selected-stream isolation coverage
-- 4000/65536 rollover, duplicate, gap, and coherent-window regression coverage
-- Waveform/RMS same-window evidence
-- Maintained field-evidence template for Windows/Npcap smoke and 30–60 minute soak validation
+### v1.4.0-beta.1
+
+- Immutable selected-stream runtime generations with copied samples and diagnostics
+- Atomic snapshot publication boundary for coherent consumer reads
+- Classic Ethernet PCAP replay through the same raw analyzer path used by live capture
+- Bounded PCAP parsing with endian and micro/nanosecond timestamp variants
+- Replay, immutability, capture timing, truncation, and multi-stream isolation regression coverage
+- Dedicated Runtime Architecture workflow with downloadable TRX evidence
 
-## Next: runtime architecture (v1.4)
+### Later v1.4 builds
 
-- Extract `SvStreamRuntime`, sequence tracking, waveform windowing, phasor calculation, and shape analysis from the monolithic analyzer
-- Publish immutable per-stream snapshots
-- Add PCAP replay as a first-class test and demonstration path
+- Extract the complete `SvStreamRuntime` from the monolithic analyzer
+- Extract sequence tracking, waveform windowing, phasor calculation, and shape analysis into independently tested components
+- Migrate the live WPF workspace to immutable runtime generations
+- Add PCAPNG and a maintained sanitized golden replay corpus
 - Add memory/CPU soak tests and observable performance budgets
+- Add replay controls and evidence selection to the user interface after the engine boundary is stable
 
 ## Next: protocol and SCL maturity
