Publish the GPT-5.6 Luna row and show only suite 3.0 results - #413
Conversation
Add the gpt-5.6-luna high-effort row to the ScaffBench 3 board and remove every result from suites 1, 2, and 2.1, whose numbers are not comparable to 3.0. Rename the Ox Alpha Free row to GLM 5.3 Flash, which is the model that actually ran, and give the leaderboard a readable layout with confidence intervals.

Publisher bypasses rendered data
When the documented suite 3.0 publishing workflow regenerates benchmark data, it writes components/scaffbench/scaffbench-3-data.ts, but this leaderboard imports its models and cells from components/home/scaffbench-3-board-data.ts, causing successful regenerations to leave the public rows and metrics unchanged.

💡 Codex Review
Better-Fullstack/testing/scaffbench-3-glm-5-3-flash-2026-08-22.md
Lines 156 to 159 in 86ae2f6
This committed run record explicitly says the cache-v8 canonical recordings and weak-versus-strong calibration have not run and that the result must not appear on the public board, but the same commit adds GLM 5.3 Flash to the live board. Publishing it before those gates close exposes a result the repository's own evidence labels unfit for publication; either complete and record the gates or keep the row hidden.

Wire published rows into the canonical generator
This file claims to be generated from run summaries, but the only publisher still has an empty RUN_SOURCES and writes apps/web/src/components/scaffbench/scaffbench-3-data.ts, not this board-data file; the commit also leaves benchmarks/ with no suite-3 summaries. Consequently bun run scripts/benchmarks/build-scaffbench-3-data.ts throws immediately and neither published row can be reproduced or revalidated from the committed publication path.

Replace the 75/25 pass-or-fail index with a graded per-spec score: 0.6 for a Core pass, 0.2 for the share of lint and format gates green, 0.2 for the stack score (wired libraries, traps, restraint). Tests weigh nothing, since the harness can only run the tests the model wrote and cargo/go pass with none. Each spec carries a pinned difficulty (1, 2, 3) and the index is the difficulty-weighted mean times 100, so a new row never moves another row. Cost, time, and lines of code stay visible columns outside the index. Add --top-up N to extend a finished pass@1 out-dir with trials 2..N for every recorded spec under the same seed. Top-ups are appended to metadata.runProtocol.topUps; the publisher emits per-spec trial counts and rates, and a row whose specs carry different trial counts publishes as partial and exploratory. Board: GLM 5.3 Flash 69 -> 58 (exact, from its per-gate report). GPT-5.6 Luna 88 -> 73, the lower bound; its cells record Full only, so the exact value (73 to 83) needs the run summary rebuilt on the bench box.

…ode drops, make the index the headline Validator cache v9: a prerequisite command whose root or project root holds a package.json now gets a bun install first (recorded as prerequisite:NN:<cmd>:install, a core step) and runs with node_modules/.bin on PATH. Under v8, buf generate could never find an npm-installed plugin such as ts-proto, so frontier-polyglot-proto failed before install for every model. The opencode adapter now marks a session that did tool work and then ended on a zero-token "unknown" step as opencode-unknown-zero-usage-step, and classification treats it as provider infrastructure. The old guard only caught sessions that died before doing anything, so a request dropped mid-flight scored as a model failure. A refusal with assistant text and no tool work stays model-owned. The quality tier is Core plus lint and format; tests run and are reported but affect no score, matching the graded index. The publisher sorts by index and emits qualityPasses / qualityPassPct / index instead of fullPasses / fullPassPct / scaffIndex. Docs and the README describe the index as the headline. The GLM 5.3 Flash elixir cell becomes a quality pass, since only its tests were red.

Revalidate v8 rows before mixing them with v9
The committed GLM report records this row under validation cache v8, while the board now mixes it with the v9 Gemini row and the current publisher accepts only v9. This cell is directly affected by the version change: v8 ran buf generate before installing the npm-provided ts-proto plugin, manufacturing a Core failure for frontier-polyglot-proto, whereas v9 installs first and the Gemini cell passes. Revalidate the older rows under v9 before comparing their scores on the same board. docs/guidelines/scaffbench-benchmark.mdL124-L124

…he Wilson interval Land the redesigned benchmark section and teaser that were sitting uncommitted: single-column layout, no sidebar, no confidence interval on the rows. The interval is gone for now; every 13-spec row carried the same ±21 to ±23 and it read as noise rather than as a per-row signal. The page now sorts and labels by the ScaffBench Index instead of the interim working-stack score. Each board cell carries its graded per-spec score (0.6 core + 0.2 lint/format share + 0.2 wired) and the spec list carries the pinned difficulty tier, so the index is computed client-side as the difficulty-weighted mean and the spec filter keeps working. For the full board it reproduces each row's sortIndex exactly (Luna 73, GLM 58, Gemini low 63). Gemini's cell scores come from the harness summary; GLM's from its per-gate run report; Luna's are the lower bound already noted in the data file.

Exclude Svelte build output from the LoC cell
When the Gemini Svelte project builds during generation, measureProjectCode() traverses .svelte-kit because that directory is absent from PROJECT_WALK_SKIP_DIRECTORIES; the source summary correspondingly reports 23,065,207 bytes and 220,342 lines here, versus roughly 1–10k lines for most other cells. The Code scatter and leaderboard then average this generated bundle as authored code, inflating Gemini's displayed LoC to about 19.8k; exclude SvelteKit build directories and regenerate this metric.

…page Scoring: a spec earns quality credit only when Core passed and lint/format gates actually ran. A multi-root project whose Bun root linted green before a Go or Cargo root failed Core no longer keeps the 0.2 quality share, and a --no-quality-gate run earns none. Top-ups: --top-up is rejected together with --validate-existing and --write-matrix-only (both would skip or clobber the new trials), restores the recorded --max-budget-usd, and defaults to every recorded spec unless --specs was typed, so an extended spec never silently becomes a partial top-up. Publisher: percentages come from the unrounded macro rate; META reports launchRepeats alongside trialsPerSpec derived from the published rows. Board page: Steps column and chart tab removed (no suite-3 row measures it); exploratory rows sort after ranked rows and carry no rank number; the index axis and values drop the % suffix; the free tier is decided by the model id, not by a measured $0, so subscription adapters stay out of it. Redirects for the four retired blog posts point at /benchmark. The SEO contract fixture uses a post that still exists. Code metrics: .svelte-kit, .output, .nuxt, .vercel, .turbo, .wrangler are skipped in the project walk. The Gemini svelte LoC cell is null until the archived project is re-measured. Docs: board renderer named, dropped test removed from the lane, quality credit rule stated, and the published rows described as pass@1 previews ahead of the calibration gates.

Mark the uncalibrated leaderboard as a preview
Fresh evidence in this revision is the owner-decision rule in docs/guidelines/scaffbench-benchmark.md:161, which permits these uncalibrated rows only as previews and requires the board to retain its preview label until canonical and weak-versus-strong calibration finishes. The new leaderboard and homepage instead present Gemini as ranked and “leading” without any visible qualification; a repo-wide search finds preview only in unused data metadata, so visitors interpret provisional results as final. Render a visible preview notice on the board and teaser until those gates are complete.

Problem
The ScaffBench board mixed results from four different benchmark suites. One row came from suite 3.0, four more were pulled from the 2.1 and 2.2 data files and rendered behind a "legacy" badge. Those suites scored different specs under a different protocol, so putting them in one sorted table invited readers to compare numbers that were never comparable. The 3.0 row was also attributed to "Ox Alpha Free", which is an opencode stealth alias rather than a model name.
Separately, the board had no result for GPT-5.6 Luna, which is now the strongest row we have measured under the 3.0 protocol.
Solution
The board now renders exactly the models we have actually run under suite 3.0, and nothing else.
GPT-5.6 Luna joins the board. Pass@1 of 11/13 core and 5/13 full, wired-libraries at 97%, command discipline at 100%, zero inconclusive runs, at $0.69 per spec. Provenance matches the 3.0 protocol on every field the publisher checks: suite 3.0, harness 3.1.0, validation cache v8, prompt
2026-08-21-scaffbench-3.1, resource profilelow-2w-v1, explicit prompt style. The harness rates itranked.Ox Alpha Free is renamed to GLM 5.3 Flash. The stealth alias has since resolved to Z.ai's GLM 5.3 Flash, and
opencode modelsnow listsopencode-go/glm-5.3-flashdirectly while the oldopencode/x-preview-f-freeid has left the catalog. The row keeps its measured numbers and gains a Z.ai logomark. The build script carries the id-to-label mapping so a regeneration cannot silently restore the alias.Results from suites 1, 2, and 2.1 are removed rather than relabelled, along with the four blog posts that published them, their localized translations, and the eight publisher and splice scripts that generated them. Keeping them behind a badge implied they belonged on the same axis as 3.0 rows.
benchmarks/README.mdnow says where they went and that git history still has them.The leaderboard is readable at a glance. The model column is fixed and wide enough that a name and its effort tag are never clipped, rows are separated by rules, and Pass@1 carries the 95% Wilson interval both as a
±figure and as a whisker drawn over the bar. This matters more with two rows than five: Luna's interval is 18-64 and GLM's is 4-42, so they overlap heavily, and a bare percentage hides that a 13-spec single-trial run cannot separate them.Row color and logomark now key off the model's vendor rather than the harness it ran through, so a lab reads the same in the scatter plot and the table. The harness moved into a tooltip on the model name.
The homepage teaser was computed entirely from 2.1 MCP-versus-prompt data, which no longer exists, and suite 3.0 measures the prompt path only. It now shows the leading 3.0 row's build rate against its ships-clean rate, so its claim is backed by data that is actually present.
Confidence
95%. Both rows were recomputed from the committed harness summaries and match them exactly: Luna at 11/13 core, 5/13 full, $0.686 per spec, and GLM 5.3 Flash at 8/13 core, 2/13 full. Deleting the older suites is the reversible half, since the reports remain in git history. The residual risk is presentational, not numerical: the table layout was verified by reading the grid definition rather than in a browser.

The PR should not merge until the live leaderboard is connected to the canonical publisher and its numeric confidence labels accurately represent the intervals being drawn.
The current publishing workflow cannot update the row data consumed by the live board, and both published rows present Wilson intervals using misleading symmetric ± values.
