Code Currents

Code Currents/camilochs/exacttexagentic

The trunk is a helix, and both of its coordinates are data. Height is time, compressed logarithmically so that a burst of commits and a three-day pause both stay visible. The angle advances one step per commit, so the pitch of the helix is the rate of work: it coils tightly through a burst and opens into a long stretch across a pause. Each bead is one commit — its height is the lines it changed, its width the files it touched. The ticks are day boundaries. Each orbit is a unit of the repository: the radius is the area it belongs to, and the rise and fall is a vertical sine whose amplitude is how much of the unit is being redone. On any one ring the radius never changes — a unit moves up and down, not outward.

Axis and marks: the time scale itself: no data, day boundaries
Bead height: lines changed in the commit
Bead width: files the commit touched
Bead grey: share of the change that was whitespace only
Orbit radius: area of the repository: core, tests, docs, tooling
Ribbon thickness: lines currently in the unit
Tail length: how long the file has existed, in commits, absolute 0–128
Orbital speed: commits touching the unit in the last 20
Wave amplitude: how much of the unit is being redone, not extended
Ripple: hunks per file in the unit's last edit
Knot size and hue: peak cyclomatic complexity, absolute scale CC 8–40
Outer ring: hour of day the commits landed in, 0h at the top

Three of these are only partially expressive: bead grey, ripple frequency and orbital speed. Orbital speed is reliable for motion against stillness, not for a value in between.

Hue is the area of the repository a unit belongs to — the same hue on the ribbon, on its knot, and on the bead of a commit whose work fell mostly in that area.

Complexity moves a ribbon off its hue

CC 820 · haloCC 40

The scale is fixed at CC 8–40 in every repository. Normalised per repository it the reading inverts: the repository with the highest peak complexity would rank last of five.

Plain diff minus diff -w. A fully grey bead only reformatted.

Tap one to open it. One agentic trajectory and four human controls, all Rust, all pre-LLM, all over their first 172 non-merge commits. Every channel meant for comparison is on an absolute scale, which is what makes reading one against another possible at all.

Measured the same way, and outside the comparison: without a producer label it cannot join the four controls the reference documents quote.

A row is marked when the agentic value falls outside the range of all four controls. The unmarked rows are a result too: they rule out rhythm, cosmetic churn and young-code rework, which are the signals an unvalidated model would have claimed. Computed here from the same documents the viewer reads.
