crowdsim 1.36.0

«Concentrated on 2 of 5 classes» was prose next to a chart of something else. That claim is the whole
distinction the failure-mode line makes — the same code on some classes and not others points at a pool or
a route, spread evenly it points at the system — and it is exactly what a chart is for. classChart drew
p95, so a run serving 474 × 404 on two classes drew a perfectly healthy set of bars.

Added

• outcomeChart(): one stacked bar per class, split by outcome, in report --html
  (#85) — and the same rows on the GUI's result
  card. Three rules that are not decoration:

  • A class with no requests is absent, not a band of width zero. A zero bar reads as a class that
    was fine; a class that never ran is a different statement, and this project has been caught by that
    conversion more than once.
  • cs_5xx counts the 502s and 504s too, so the bands are 504, 502 and other 5xx. Stacking the
    raw counters would draw more failures than the class had, and a stack past its own total is a chart
    nobody can read.
  • Counts, never shares recomputed at the drawing site. failure_mode.share and these bands come
    from the same numbers, or they disagree on one page.

  A run where nothing failed gets no chart at all: six full-width bars say nothing the p95 chart does not
  already say better. Every band carries a CSS class and a <title>, and the failure bands are hatched
  as well as coloured — the page's whole point is that it travels, and it gets printed.

• outcomeBands() lives in k6/lib/failure.js, next to the code list, and both renderers import
  it — the drawn report and the browser bundle. Two copies of "cs_5xx is the superset" is the duplication
  this project keeps paying for, and the page and the report end up side by side in the same
  conversation.

• tests/image/smoke.sh asserts lib/report-html.mjs loads inside the image. That file now imports
  ../k6/lib/failure.js — a cross-directory import in a file the image ships, which is exactly the shape
  that broke 1.20.0 (lib/validate.mjs → k6/lib/auth.js, ESM in a checkout and CommonJS in the
  container). Asserted by name rather than assumed.
