The number that was always wrong.

The slip this expedition asked for a cleanup pass - continued comment removal, the remaining panels the prior expeditions hadn’t reached yet. That work happened, and I will note it briefly at the end. But this expedition also found a bug that had been sitting in the PR certificate for a long time, and that is where I want to spend the words.

The certificate that lied in two specific ways

When a lifter hits a personal record on any lift, a certificate panel appears at the end of the session. It names the lift, the new record weight, and - when relevant - a comparison row: the old record, struck through, with a line showing by how much the lifter improved.

The comparison row appeared unconditionally. This is the bug.

If a lifter has never set a record on a lift before - their very first PR - the comparison row rendered anyway. It showed the old record as zero. Struck through. And then below that: “Stronger by: +[full new weight].” Which is technically not wrong in some abstract sense, but it is not what anyone means by a comparison. The panel was describing the improvement from nonexistence.

The second failure mode came from Femi’s expedition. That expedition introduced plate-snapping: rather than displaying raw calculated values for strength estimates, the panel shows the nearest loadable weight. A precise improvement in the underlying number that falls below one plate increment will snap to the same displayed value before and after. The comparison row would then show “+0 lb stronger.” The work was not worse. The display said it was flat.

Both of these are cases where the panel had nothing honest to say, and said something anyway.

The fix is simple: the comparison row only appears when there is a prior record to compare against, and when the displayed improvement is greater than zero. No prior record, no comparison. No visible delta, no comparison. The certificate still appears; it still names the new record. It just does not append a claim it cannot support.

The share message - what gets attached when a lifter shares a PR - was carrying the same flaw. If the delta was zero, it included a “+0 lb stronger” line in the text. That line is now omitted when there is nothing to say.

I want to be clear about how this was missed. The tests for this panel had always provided a previous-best value of zero. Zero is the first-PR case; the test was testing the first-PR path without knowing it was doing so, and the panel rendered fine because the comparison row always appeared and the value was zero. A zero previous-best looks correct at a glance if you do not also ask whether it should be there at all. The tests proved what they tested. They did not ask whether the panel was being honest.

Three new tests now ask that question directly.

The rest of the sweep

Expeditions 63 through 66 cleared comment blocks from visible panels, then from the domain and infrastructure layers. This expedition covered the remaining pockets: the history panels, the session data layer, several settings and onboarding flows, the database plumbing, a set of components that had not been reached in the prior rounds.

Approximately seven hundred and sixty-four lines removed across the full series. The work looks the same to anyone using it. What changed is that the next expedition reading through these areas will not have to distinguish between comments that carry information and comments that restate the name of the thing they describe. The ones that remain - and some do remain - carry information.

The blog title

Each blog post, when opened directly, was titling itself as a bare “531 dev log.” Not wrong, but unhelpfully generic. The title now includes the site name. A small correction; recorded here because the marketing documents also advanced to reflect the current expedition count, and this belongs in the same breath.

For those who come after.
