80 completion-selected outcomes across two tool cohorts; 83 observed paid primary attempts and 52 prerequisites. This is a descriptive snapshot, not one randomized five-CLI experiment. Full experiment cost is unknown. Three partial native captures retain valid required grade artifacts. Native tool timing remains partial. Read result interpretation and native workflow findings.

How to read this analysis
Pass = completed native verification; verification failure = verify_error; other = timeout or adapter_error. verify_error alone does not distinguish task failure from verifier infrastructure failure. Failure timing stays separate and is not ranked against passes.
Coverage counts all selected attempts. Each metric has its own valid n and missing n; timing, usage, caching and cost denominators can differ. Unavailable is not zero.
IQR tasks counts successful timing tasks with at least two eligible repetitions, out of all successful timing tasks. Headline spread is the median measurable within-task IQR, not pooled spread.
Outcome spend is the sum of selected static estimates. When any costs are missing, the displayed amount is only a known subtotal. Failed attempts and other outcomes are reported separately from pass spend.
Distributions describe repetitions within one task, harness/version and outcome. Q1–Q3 and min–max describe observed samples, not confidence intervals; singleton quartiles are unavailable.
Matched comparisons include only common successful task identities. Each task contributes one within-task median; summary times are medians across those task medians. The descriptive ratio is the median of right / left task ratios, not a causal effect or ratio of unrelated headline medians.
Task identity includes base revision, verifier image and environment. Repetitions are not paired seeds; execution windows can differ. Recorded host fields do not establish machine identity.
Request metrics come from sanitized C1 model attempts. Wait is first-byte minus request start; transfer is last-byte minus first-byte. Synthetic first-byte markers from network failures are unavailable. Gaps exclude overlapping model intervals; time after last is reconciled adapter end minus the latest response end. Request summary duration, wait, transfer and gap columns are medians of within-run medians, with metric-specific available and missing run counts.
Timing uses the existing C1 interval-union derivation. Unreconciled timing is unavailable; outcome groups remain separate.
Usage covers successful model responses; turns count identifiable API attempts. Static costs are not invoices and exclude attempts absent from this export.
Matched comparisons use only common tasks with reconciled native passes on both sides. Repetition indices are not paired seeds. Samples and execution windows can differ.
No matched-model comparison is produced when the recorded model is unspecified.
Host fields describe recorded hardware, not unique machine identity. Same-host populations do not establish causal harness effects.
Quartiles describe observed runs, not confidence intervals. Singleton spread is unavailable. Non-model time includes unobserved tool and harness work.
Request series are sanitized C1 model attempts: duration, wait, transfer, gaps and per-call tokens/cost. Paths, bodies and logs are not exported. Relationships are within a run or matched task, not ratios of unrelated headline medians.
