@@ -194,6 +194,7 @@ Context: 0.16.x proved that queue tweaks and static calibration cannot guarantee
 - [x] Calibration may fine-tune sub-frame offsets only; it must not be required to rescue seconds-scale desync.
 
 - [x] Bump Lesavka to 0.17.0 because this is a media-contract change, not a patch tune.
+- [x] Bump patch follow-ups to 0.17.1 instead of reporting `version+revision` as the release version.
 - [x] Add planner policy config: max live lag, max skew, startup timeout, target playout delay, and healing cooldown.
 - [x] Reset 0.17 defaults so shipped audio/video offsets do not intentionally exceed the freshness budget.
 - [x] Track latest camera/audio input timestamps in the server planner.
@@ -222,3 +223,4 @@ Context: 0.16.x proved that queue tweaks and static calibration cannot guarantee
 - 2026-05-01: Validation green: `cargo test -p lesavka_server --lib --bins`, `cargo test -p lesavka_testing`, `cargo test -p lesavka_client --bins --lib`, and targeted installer/RPC/layout contracts.
 - 2026-05-01: First installed 0.17.0 mirrored browser probe on client/server commit `3920e0a` failed honestly: planner reported fresh live state (`live_lag_ms=10`, `skew_ms=+20.7`) but browser-observed paired pulses showed audio late by median `+349.1ms`, p95 `429.1ms`, with 6 video freezes/skew drops. Replayed artifact after analyzer hardening now reports `gross_failure` instead of false raw-start `catastrophic_failure`.
 - 2026-05-01: Patch follow-up models the observed MJPEG/UVC browser egress delta by defaulting video playout offset to `+350ms` and preserving the 1s freshness ceiling. Raw activity-start evidence is now ignored for verdict/calibration when it disagrees with paired pulses that are already failing directly. Existing early-0.17 `audio=0/video=0` factory/env calibration files migrate to the new `video=+350ms` default on load.
+- 2026-05-01: Release identity cleanup: bumped the patched build to clean semver `0.17.1`; probe attribution now prints `client_version`/`server_version` separately from `client_revision`/`server_revision` and refuses old `client_full_version` output.
