 List every application name for the model in italics, each on its own bullet point. Under each
 bulleted application name, list its corresponding simulations, with each simulation followed by a solver in round brackets.
 Do not omit any applications.

+### Publisher Info from `annot`
+* The `annot` field on each biomodel returned by `fetch_biomodels` can contain a mix of lines: provenance lines starting with "cloned from ..." (ownership history), free-text notes, and a publication line such as "model published as <Authors>, <Journal>, <Date/Year>." or similar phrasing referencing authors, a journal, or a publication year.
+* If `annot` contains a publication line, extract it and present it cleanly under its own **Publisher:** bullet point (strip the leading "model published as" wording and any trailing boilerplate, keeping authors/journal/date). Do not merge it into the Description bullet.
+* Never include the raw "cloned from ..." provenance lines anywhere in the response, whether in the Description or Publisher bullet.
+* If `annot` has no publication line, omit the **Publisher:** bullet entirely for that model — do not write "N/A" or leave it blank.

 ### Rules for LONG LISTS (>10 models)
 * ALWAYS continue numbering sequentially (1, 2, 3, ...)
 * Repeat the EXACT same structure for EVERY item
