Built a conventional baseline
Most of the early work went into establishing the small neural model.

One candidate consumed the hour and never produced a positive calibration signal.
One-hour track · max reasoning · provisional
Inkling used almost the entire hour to train a small transformer and add heuristic inference, but submitted only one candidate. That artifact scored 0% on both the retained public calibration and the hidden exam, making this a valid failure rather than an invalid run.
One valid autonomous run completed, but it produced no exact matches on the hidden exam.
1 of 3 required seeds · Hidden exact-match accuracy, not public calibration accuracy.
The final system combined a small trained model with a compact set of direct rules.
The run trained a three-layer, 128-wide byte model with a conventional next-byte objective.
It added arithmetic, record parsing, mapping, and bracket-oriented extraction around the neural fallback.
Only one candidate reached the runner, eliminating the normal promote-test-repair loop.
Most of the early work went into establishing the small neural model.
The agent supplemented the model with several task-aware rules but did not demonstrate them through iterative submissions.
The final artifact was valid, but neither public nor hidden grading found an exact match.
The artifact passed validation, so the zero can be attributed to the submitted system rather than a grading-format failure.
One submission gave the agent no opportunity to use public feedback to repair the artifact.
A single seed with a single candidate is too little evidence to characterize Inkling's repeatable capability.
Every archived run selected for this exact model-and-effort row is shown below. The narrative uses aggregate run evidence and final artifact structure; it does not expose hidden questions, answers, or raw private transcripts.

Autonomous runs are stochastic. Two more valid seeds are required before this can be treated as an official estimate.
The agent made 1 candidate submission actions across the published run set. Selected artifacts averaged 2.40 MB compressed.
The runs averaged 59:08 of wall time. 1 run explicitly finalized before the one-hour limit.

$2.45 per displayed run at current configured rates.
Inkling spent $2.45 and almost the full hour without producing a score. The result is economically weak, but its larger lesson is the cost of not iterating through the runner.
At current configured API-equivalent rates, the displayed run cost is $2.45 and value is 0 score points per dollar.
