title: 2026-07-09 — SPA gates Download Media Sample while a session is active
status: active
since: '2026-07-09'
supersedes: none
superseded-by: none
rule: The SPA disables both Download Media Sample and Download Results while a troubleshooting session is starting/running (Blazor only gated Download Results).
signals: 'I/O contention with the live transcode · paths: none · issues: none cited'
mechanics: playback-troubleshooting screen
---

Minor intentional deviation: the SPA playback-troubleshooting screen disables **Download Media
Sample** (alongside Download Results) while a troubleshooting session is starting/running; Blazor
only gated Download Results. Both downloads compete with the live transcode for I/O and the sample
archiver reads the same media file, so gating both during a session is strictly safer and costs
nothing (sessions are short).
