18 finalized runs across 3 model configurations, 3 task types, and 2 prompting conditions.

This archive documents an 18-run frontend generation exercise across three task types, three model configurations, and two prompting conditions. It is provided as a transparent showcase of the work performed, not as a controlled study, model ranking, or claim that one approach is superior. It is non-evaluative: it does not identify a winner or support causal conclusions.

Timing caveat

Completion timestamps were recorded independently by the orchestrator immediately after each agent's final status was returned by the wait mechanism. The official elapsed values above therefore include queueing and tool-execution time and may include the minimal status-observation handoff between tool return and timestamp capture.

Recorded duration999 seconds
Findings1
Timing caveat

The orchestrator captured Luna and Sol return timestamps immediately after their `wait_agent` calls completed. Terra’s wait result was surfaced as a completion notification before a receipt timestamp was captured; its exact completion timestamp above is the timestamp included in Terra’s returned completion report, so Terra’s official observer timing has a reporting-source limitation. No timestamps were estimated or rounded. The first wait window expired after ten minutes without a result, but all three agents were kept running and subsequently completed. This did not change the dispatch timestamps or the final completion records.

Timing caveat

Timing limitations, interruptions, retries, or tool failures: No agent retries or interruptions. An additional orchestrator read-only filesystem audit of the implementation directories was attempted but rejected by the environment safety reviewer as unrelated/untrusted transcript inspection; therefore file inventories and RUN.md contents are reported from the agents' final completion results, not independently re-read by the orchestrator.

Timing limitation: the orchestrator captured dispatch immediately before each spawn and completion immediately after each concurrent wait returned. The wait results surfaced together, so the three observed completion timestamps are clustered within 68 ms; these are the official orchestrator-observed benchmark timings.

How to read this archive

Archive context

Archive matrix

3 × 3 × 2

Three task types, three recorded model configurations, and two prompting conditions. Luna and Terra used xHigh reasoning. Sol used High reasoning. These archived runs are not a controlled comparison.

Screenshot provenance

15 original artifacts · 36 derived captures

The sanitized publication contains 15 original screenshot artifacts belonging to 1 run with original screenshot evidence. The showcase adds 36 standardized publication-time derived captures, providing a consistent archival reference for 18 runs.

No model was rerun.

No implementation was regenerated or repaired.

The publication-time derived captures do not reconstruct the exact original runtime environment. Original benchmark screenshots remain separately labelled where available.

Recorded timing

Timing records are preserved as execution evidence, not as controlled performance measurements. Individual durations retain manifest caveats: they include orchestration, tool execution, and observation handoff.

Read before concluding

Limitations

Limitation 01

Publication-time captures show how the finalized sanitized implementations rendered in the showcase capture environment. They may differ from the exact browser, font, timing, or operating-system conditions present during the original benchmark execution.

Limitation 02

This archive is not a controlled scientific experiment, model ranking, or basis for causal or superiority claims.

Limitation 03

Luna and Terra used xHigh reasoning while Sol used High reasoning; these are recorded configurations, not matched reasoning levels.

Limitation 04

The selected task types are illustrative rather than representative, and model outputs are nondeterministic.

Limitation 05

Recorded durations include orchestration and observation caveats and must not be interpreted as controlled performance measurements.
