Read REVIEW_COMMON.md (repo root) first - its contract binds this checklist. Architecture doc: README.md.

Every hand-written shell command shown on a page runs verbatim and produces the result the page shows. A command, flag, or output line invented for illustration is a defect; if the implementation does not exist yet, the page does not show the command.

The cmd field of any run in files/dasllama/bench_records.json is the exact argv modules/dasLLAMA/performance/gen_bench_records.das (or the released bench exe it spawns) ran. A receipt is per run - one cmd + date run object - never per rendered row.

files/dasllama.js shows a run's receipt line on every row that run produced. One run's cmd + date covers several rendered rows; a row rendered without its run's receipt line is a defect.

files/dasllama/bench_records.json is generator output: modules/dasLLAMA/performance/gen_site_records.das merges every modules/dasLLAMA/performance/records/<box>.json and applies modules/dasLLAMA/performance/records/annotations.json, so re-running the generator leaves the file byte-identical. A diff where it does not is a hand edit and a defect.

files/performance_bench.json is generator output: benchmarks/sql/_update_results.das --site-json writes it from the same sweep output that regenerates the tables in benchmarks/sql/results.md. A diff that changes files/performance_bench.json without changing benchmarks/sql/results.md in the same change, or that leaves any cell in the record differing from the same family-and-lane cell in the results.md tables, is a defect.

files/performance_engines.json is generator output: examples/benchmarks/sql/_update_results.das --site-json writes it from the same sweep output that regenerates the tables in examples/benchmarks/sql/results.md. A diff that changes files/performance_engines.json without changing examples/benchmarks/sql/results.md in the same change, or that leaves any cell in the record differing from the same family-and-lane cell in those results.md tables, is a defect.

benchmarks.html renders only the vendored dasProfile records - the same files/profile_results_<platform>.json files pages.yml fetches from borisbat/dasProfile at deploy time and files/forge.js's front-page cycler reads. A benchmark number hand-carried into the page or a second record file for the same data is a defect; provenance (the das_capture / ext_capture stamps) travels in the dasProfile files themselves.

Every code sample shown on a page is a full program - it compiles and runs with the current toolchain, and the page links it to "try it on playground". daslang samples are gen2; a partial snippet shown as a code card, a sample without its playground link, or pseudo-code presented as code is a defect.

A test under tests/playground/ (this folder) that needs the daslang runtime carries @wasm in its title. The per-PR lane stages the site without WASM artifacts and runs the suite with --grep-invert '@wasm' (playground-e2e.yml), so an untagged runtime-dependent test fails every PR.

A change to the deployed playground sources - playground/ (this folder), web/examples/ui/src/, or web/examples/ui/samples/ - ships with a stated run of the WASM-staged Playwright suite (tests/playground/, this folder), naming the result - passes and any failures - in the PR body or commit message. The run also names its runtime artifacts: built from this change when the change feeds web/output/daslang_static.*, the deployed ones otherwise. The no-WASM lane cannot see a broken runtime path, and every sample on the page runs through that path.

Every number on a page that reports a measurement - a rate, a duration, a size, a score some run produced - is rendered from live data, copied from a checked-in measurement record, or carries a source comment naming it a placeholder. A placeholder that could be mistaken for a fact is a defect. A number stating a fixture or a run parameter (an image's dimensions, a token budget) reports no measurement and is outside this rule.

A dl-* selector defined in BOTH files/dasllama-table.css (the file dasllama.io loads) and dasllama.html's inline <style> copy keeps identical bodies. Changing one copy and not the other is a defect.

A dl-* selector is defined where its markup lives - the markup a page renders, including what files/dasllama.js injects: a selector dasllama.html renders is defined in dasllama.html, and in files/dasllama-table.css too when site-dasllama/'s pages (repo root - the dasllama.io site) render it as well; a selector only site-dasllama/'s pages render is defined in files/dasllama-table.css alone.

News entries state real, shipped events. An entry in _news/*.md for something not yet true at publish time is a defect.
