+## [0.9.3] — soak validation + test coverage (no runtime change)
+
+### Tested
+
+- Full-stack soak validation — 15 cases, leak-free and correct under load on a prod host + an
+  isolated VM. Observe: steady 20 min, edge-input, a real a3s-code agent, throughput (110k ev/60s),
+  memory-bound (256 Mi), restart ×8, idle + heartbeat, SIGTERM, concurrent collectors,
+  backpressure, connection-churn. Intervene: egress, file/exec, and SSL-content guards — plus all
+  three running alongside the collector.
+- Lib line coverage 72% → **79.6%** (`cargo llvm-cov`): adversarial SNI/DNS parser tests, the
+  cgroup→pod parser, the full 14-provider SNI classifier, and the v0.9.2 writer-thread path.
+
 ## [0.9.2] — fix: output backpressure no longer stalls the event loop

+## Tested
+
+Soak-tested under sustained load — observe on a production host, intervene in an isolated VM:
+
+| path | cases (all leak-free + correct under load) |
+|---|---|
+| **observe** | steady 20 min · edge-input · **a real a3s-code agent** · throughput 110k ev/60s · memory-bound (256 Mi) · restart ×8 · idle + heartbeat · SIGTERM · concurrent collectors · backpressure · connection-churn |
+| **intervene** | egress · file/exec · SSL-content guards — and all three running alongside the collector |
+
+Two robustness bugs surfaced and were fixed this way: NDJSON stdout pollution (v0.9.1) and an
+output-backpressure event-loop stall (v0.9.2). Lib line coverage **79.6%** (`cargo llvm-cov`) —
+the untrusted SNI / DNS / cgroup parsers and the full 14-provider classifier are unit-tested.
