## Unreleased

## v68.3.0 (2026-05-21)

### Detection Evasion
- **Ad spoofing default flipped on → off** — was previously on by default with a localStorage opt-out (`twitchAdSolutions_disableAdSpoofing='true'` to disable); now off by default with a localStorage opt-IN (`twitchAdSolutions_disableAdSpoofing='false'` to re-enable). Rationale: convergent signals that the spoof's always-100%-watched + audible + visible beacon pattern (fires before a human would plausibly have watched the ad) may itself fingerprint as anomalous in Twitch's anti-adblock heuristics — silent fingerprinting that vaft's `GQL response status` surveillance line (which only catches loud rejections) cannot detect. Field signal: an in-stream ad reaching the committed autoplay 360p backup on `warn` despite full vaft pod coverage and 100% Twitch acceptance of the spoof beacons (i.e., consistent with detection escalation rather than spoof rejection). Convergent with the TTV-AB maintainer's hypothesis. Mechanism retained intact: users who want to A/B test or explicitly opt in can set `twitchAdSolutions_disableAdSpoofing='false'`. vaft only (#NN)

Field signal: a Twitch ad overlay with countdown reached the user during an ad break on `warn` while spoofing was on, despite full vaft pod coverage and 100% Twitch acceptance of the spoof beacons — though the precise mechanism by which the spoof would drive overlay rendering is unverified (Twitch's player UI is driven by local m3u8 ad-cycle tracking, not GQL response — but a server-side coupling is plausible). Convergent with the TTV-AB maintainer's hypothesis. Mechanism retained intact: users who want to A/B test or explicitly opt in can set `twitchAdSolutions_disableAdSpoofing='false'`. vaft only (#NN)
