Current release / ZJX 1.25.1 NIGHTMARKET
Two explicit packing objectives: compact searches for the smallest complete archive; fast trades packing time for cost inside strict archive-size and restore-cost guardrails. The fastest schedule we tried was rejected for making restores slower.
What changed
NIGHTMARKET introduces objective-driven packing. Compact is the canonical no-argument default: an exhaustive size-first search that keeps the smallest complete archive in the eligible candidate universe. Fast is a fixed reduced schedule, promoted from the former experimental balanced schedule and qualified independently under the unchanged fast contract.

Qualification result
Controlled NIGHTMARKET qualification campaign. See methodology and evidence.
Positive-median wall savings in 4 / 4 primary corpus families across 48 / 48 pack starts.
Methodology
Four corpora, six matched pairs per corpus, two arms per pair with alternating order, a deterministic paired-ratio sign-test interval at alpha 0.05, no outlier deletion, no post-result tuning, and no pooling with earlier measurements. The campaign ran on a dedicated, quiesced laboratory host.
Limitations
Performance ratios apply to the frozen laboratory host, four corpora, commands, repetitions, and thresholds of the qualifying campaign. Fast carries a published size budget: the campaign observed no penalty, but other inputs may trade some size for time within explicit bounds.
Customer savings language
At the NIGHTMARKET qualification ratio, a workload requiring 1,000 minutes in compact mode would require approximately 364 minutes in qualified fast mode, avoiding approximately 636 minutes of wall time.
Modeled from the NIGHTMARKET qualification wall-time ratio. Actual savings depend on workload, hardware, configuration, resource utilization, and infrastructure pricing.
Historical context
ZJX 1.25 was published as a private, authenticated release and withdrawn before public distribution: its runtime reported the fast objective as production-qualification-pending, contradicting the release claim. ZJX 1.25.1 corrected that status string, added a regression assertion for the exact API surface, and underwent a fresh exact-byte qualification cycle with new binaries, a new 48-start campaign, and new release validation.
