# KmPlot computer app

Exported by REA's `export-desktop-application` from a capture of the `kmplot` package
(capture Evidence `ev_d8ffd3e13d18b512c3269712baf199a9ad9e5890e664ca6dd4d5822ca14f1122`). It was checked against agentenv-framework
0.9.1431.

- `envs/kmplot/` is a computer app on the `ubuntu-24.04` base with the `reference` driver, for
  `amd64` and `arm64`. It installs `kmplot` from the distribution archive, launches `sh -c cd "$HOME" 2>/dev/null; exec 'kmplot' "$HOME"/'Documents/lesson_plots.fkt'` at boot and is ready
  when a window of class `kmplot` appears.
- At launch the app opens `~/Documents/lesson_plots.fkt`, the seed's one document.
- Owned paths: `~/.config/kmplotrc`, `~/Documents`.
  `data/get` returns their files and a typed JSON view of each; `data/reset` restores the seed.
- Seed: 2 file(s) made for the task, as saved at checkpoint `seed`.
  Text files and dconf keys spell the capture host's name as `localhost`, `user@host` as `user@localhost`
  and the home as `/home/user`, which the computer respells to its own at boot.
- Neither owned nor seeded, so the app starts without what it saved there: these files or folders, which changed
  during the capture, `~/.config/QtProject.conf`.
  To own them, capture again naming them with `state_paths` on `start_build_capture`, or `--state-path` on `capture-desktop-application`.
- `tasks/smoke.json` deploys the app.

Run the task with `agent-env run <this folder>`, or only the deploy with `--task smoke`.

The seed was made for this task, not taken from a user's own data; read `envs/kmplot/seed/` before publishing the bundle.

## Task `change-h-formula`

`tasks/change-h-formula.json` deploys the app, has the agent work through the computer from the prompt below, and grades
the outcome with `artifacts/change-h-formula-check/verify.py`, which reads the app's `data/get` views and needs
no model. It grades once the app's files have held for 3 s, so a save the app makes on its own within that
time of the agent stopping counts; each result's `settled` is false when they were still changing 15 s after the
first read. `evals/kmplot.toml` names it, so a run of the bundle runs it.

> In KmPlot, change the formula of the function h in Documents/lesson_plots.fkt to h(x) = 2x + 1 and save the plot file.

Checks, each of which must pass:

- `h-new-formula`: `{"kind":"line_count","file":"Documents/lesson_plots.fkt","contains":">h(x) = 2x + 1<","equals":1}`
- `h-old-formula-gone`: `{"kind":"line_count","file":"Documents/lesson_plots.fkt","contains":">h(x) = 0.5x + 1<","equals":0}`
- `g-unchanged`: `{"kind":"line_count","file":"Documents/lesson_plots.fkt","contains":">g(x) = 2sin(x)<","equals":1}`
- `f-unchanged`: `{"kind":"line_count","file":"Documents/lesson_plots.fkt","contains":">f(x) = x^2","equals":1}`
- `three-functions`: `{"kind":"line_count","file":"Documents/lesson_plots.fkt","contains":"<function ","equals":3}`

REA kept the task because its checks fail on the seed (`h-new-formula`, `h-old-formula-gone`) and all
pass on the captured end state.

To measure a solve rate, run the task k times (3 by default) with the agent and model to measure, and count the runs
whose summary line says `passed`; a run that says `failed` did not finish and is run again rather than counted:

    agent-env run <this folder> --task change-h-formula --agent claude-code --model MODEL
