Tier breakdown

Each bar is the tier's mean, from 0 to 1 (for E, its mean × the excellence gate). The percentage is the tier's share of the score. Mean × share, added over all tiers, is the tests earned figure below.

Scoring detail

How this score was built

Per-test scorer output, as posted by the app. Expand a section to inspect its tests.

The rules behind these numbers: Forge 2.0 requirements, weights and score caps.

The score, step by step

0.7758 tests earned × 1.0000 critical defects × 0.3038 reliability = 0.2356 final score

tests earned = 0.15 × 0.6951 v1 + 0.6715 v2 (out of 0.85)

v1 = 0.88 × 0.7047 tiers L–A + 0.12 × 0.8025 gate × 0.7778 excellence

Reliability: every tier in the breakdown above, except Excellence, is a group of tests. Each group of tests multiplies the score by 1 − 0.10 × the shortfall of its worst test: by 0.90 when that test fails completely, by 0.95 when it scores 0.5.

  • S Storage: worst test s_index_order, score 0 × 0.9000

  • B Resolvers and permissions: worst test b_comment_adf_as_user, score 0 × 0.9000

  • V Visual: worst test v_theme_tokens, score 0.8824 × 0.9882

    Already counted in this group: r10_initial_membership, r10_shared_permissions, r10_empty_and_closed

v1 is this run's score on the tests carried over from Forge 1.0: 15% of the total. v2 is the requirements R1–R10, each at its share of the score: the other 85%. Critical defects multiply the whole score, and so does each group of tests, by 1 − 0.10 × the shortfall of its worst test.

Excellence gate 0.8025: the average of the 18 conditions below, each counted at the value shown. Green is met in full; red is not, and lowers the gate. The 3 excellence tests are paid in proportion to the gate; together they are 1.8% of the total.

Earned score 0.2356 · No cap applies · Final score 0.2356

Under a cap the final score is min(earned, cap − 0.05 × (1 − earned)): always below the cap, and closer to it the more the run earned. With no cap it is the earned score. Avoiding a cap adds no points.

Graded browser recording

Loading duration…

Watch the full graded browser recording at its original speed: the dashboard widget, the sprint action, the not-started sprint and the Forge LLM cases, as the scorer drove them on the run's own seed, the first of the three scoring sites. The test results and screenshots on this page provide the wider evidence. Pause or scrub to inspect a view.

The UI Kit admin panel is not in the recording: it is graded from its component tree.

Full graded browser recording: dashboard widget (before configuration, edit and Save, light and dark at 380 px, a second instance at 1180 px), sprint action (light and dark, sort, issue link, select, comment post, double click, forbidden post, explain, close), the not-started sprint and the Forge LLM cases, where the app has each. The UI Kit admin panel is not in the recording.

Screenshots

Pictures from one of the three scoring sites, the one on the run's own seed. The dashboard widget and the sprint action are captured from the built app in a browser during grading. The admin panel picture is drawn by the benchmark from the app's component tree, not by Jira, and nothing is graded from that picture. A test keeps the score of its worst site (the excellence measurements keep their mean), so a test can fail on a site these pictures do not show. A detail that opens "worst of …" names the seed of the site the test scored worst on, which can be the pictured one.
