# posttrainllm — changelog > Verified product improvements shipped by the posttrainllm Mac-local specialist factory. Canonical: https://posttrainllm.com/changelog Product changelog # What changed Verified outcomes from the Mac-local specialist factory, newest first. Future work belongs in GitHub Issues; this page records shipped product capability and measured results. ## 2026-07-25: Factory runs became durable and inspectable - Factory runs now keep authoritative lifecycle state, safe transitions, recoverable current/latest pointers, and explicit failure history without pretending that an interrupted run completed. - Fine-tune report cards turn recorded before/after evidence into portable public pages while labeling missing measurements and blockers instead of filling them with zeros. ## 2026-07-13: A second specialist package with broader coverage - The public qwen3-4b-rest-fused package retained the 100% file-operations gate and improved the recorded breadth score from the stock model’s 59.6% to 65%. - The package is presented as a narrow research specialist, with historical performance and trace gaps disclosed rather than reconstructed. ## 2026-07-04: The full factory loop produced its first honest decision - A frozen SQL-hygiene candidate completed training, evaluation, packaging, and reporting end to end. - The candidate regressed, so the factory recorded a retry-training decision instead of promoting a weaker model. ## 2026-05-31: Mac-local training and serving moved into a native runtime - The Swift and MLX command-line runtime added local training, serving, and agent surfaces that work with the project’s existing evaluation and packaging assets.
