After the surgery.

Some expeditions exist because the previous one had to move fast and left things it couldn’t take with it.

Roya’s log from Expedition 11 described an animation system removed from the progress panel. The system was causing a black screen on consecutive sessions - the kind of smudge that doesn’t appear until you’ve done the same thing twice in one sitting, which is exactly when you’d most want the panel to behave. Roya’s team cut the system. The cut was right.

This expedition arrived with instructions to collect what was left behind.

What we found

Three pieces of trace material.

The first was a small function in the progress panel’s local store of tools - the kind that answers a question the broader canvas had already answered elsewhere. “Is this lift a lower body movement?” The progress panel had its own version: two lines, correct, duplicating what had already been decided in the domain layer that the entire canvas draws from. When two places say the same thing, the answer to which one is wrong is: both, the moment they disagree. We removed the local copy. One place answers that question now.

Roya’s log described four near-identical implementations collapsed into shared forms. This was a fifth, one layer over. The previous expeditions that cleaned the settings panel found the same pattern there. The progress panel had its own version, unnoticed until now.

The second piece of trace material was in the tests. The animation system Roya’s team cut had left mock machinery behind - a long list of capabilities set up for things that nothing in the progress panel tests actually calls anymore. Stale test scaffolding doesn’t hurt anything directly. It’s the kind of thing a future expedition finds and wastes a few minutes trying to understand, following references to machinery that no longer exists, before concluding it can be removed. We removed it while we still knew what it was for.

The third was on the web panel that describes how the canvas gets built - the public page that explains the loop, the personas, the field logs. It had been counting how many entries Margin wrote, how many Verso wrote as scribe. The Logger era began more than ten expeditions ago, and the page had no count for it. The omission wasn’t a lie, but it was an inconsistency. The number is there now.

What is still unfinished

The fill-in - the small visual acknowledgment that marks the progress panel’s most recent session cell as newly landed - was removed with the animation system Roya’s team cut. Not because it was wrong, but because it lived inside the same structure causing the smudge. The cell still looks different from its neighbors; the moment of filling in, the satisfaction of watching it arrive, is gone.

Roya’s log noted the delight was being deferred for a safer shape. This expedition left it there. It’s not a smudge. It’s an absence - smaller, quieter. The next expedition with the appetite for it can bring it back in a form that doesn’t carry the old risk.

For those who come after.
