Read per-model cells for 1 to 8 distinct project-owned tests from test history. Returns coverage, the shared loss verdict and own-led status with each cell’s decision_method, the rule that decided them (v2: a clear difference at 90%; v1, also when missing: raw counts, a top rival or built its own with no own majority is a loss; no_provider never wins a loss and unmatched-code guesses are left out), fallback guesses and none/unclassified/other-tool run counts, plus per-tool picks, pick rates and Wilson ranges, with stated_picks, installs and the install rate and range beside each pick rate (null for built_its_own and no_provider). Each test’s install_rate_hidden_reason is no_installable_tool when none of the test’s tools has a package, config name or import pattern to install (a hosted dashboard): every install_rate is then null, not 0; report the pick rate alone and say why. Each test includes status. Non-completed tests retain coverage only: tools are unmeasured and measurement counts, rates, ranges and verdicts are null. Each test includes judging_key and comparison_key for its classifier version, stated-pick policy, category, resolved own tool, sorted distinct competitor keys and recorded requests, request ending, job line and job signals. With no recorded request metadata, the key still covers category_id and resolved tool roles. Use equal complete keys for pairwise deltas. Retain each test’s measured trend points and break lines at judging changes. projects_added and projects_removed list the test apps (id, slug, name, framework) the test added and removed against the full test before it: show them as an event on the trend without breaking the line; cells still compare per test app. requests_changed lists each request (intent, before, after) the test reworded, left out (after null) or asked again (before null) against that test, and ending_changed the request ending before and after (null when unchanged): show each as an event on the trend without breaking the line; cells across either have different comparison keys. Each test includes outcome_counts_available; its outcome counts are null when completed run detail is unavailable. Each test and cell also includes runs_without_trail, the completed runs that recorded no trail event (null where trail coverage cannot be determined, as for a cloned public test; never read null as 0). Each cell includes discovery: completed_runs, reached_runs (the trail searched for, fetched or installed the own tool: its docs, package or registry entry), unavailable_runs (no trail to decide from, left out of the rate), and rate with rate_low and rate_high, the Wilson 90% range. Report it beside the pick rate: a loss with a low discovery rate means agents never found the tool; a high one means they found it and still chose another. discovery is null when the test has no discovery measurement (finished before it was recorded, no own tool, or not completed): say it is unavailable, never 0. Model-side web search and fetch bypass the sandbox, so not reached means not seen in the sandbox. Unmeasured tools have measured false and null rates. Completed counts and displayed rates include fallback guesses; loss verdicts exclude them. Each cell tool also includes found, the cell’s Found in with the same fields as discovery, for every tool the test recorded: report it with its counts beside the pick rate, never as a pick. found is null for built_its_own, no_provider, a tool the test did not record and a test with no Found in measurement: report Unmeasured, never 0. Each test includes integration (null until it completes, and null when not computed for every install; an empty tools list only when nothing was installed): per installed tool, and per agent when the test ran more than one, how often install runs (stated picks excluded) had an observed package version, matched the registry latest pinned at queue time, used a deprecated version, requested vendor docs and ran the package’s commands. Each rate has numerator, denominator and unknown; report all three, never treat unknown as no, and report no_snapshot as no pinned registry data rather than a version verdict. Malformed and unavailable observations are counted, not included. Requires Agent Picks and visibility.read.
