We present a task-aware conformal framework that selects joint residual geometry according to downstream power-envelope efficiency. A residual iTransformer produced point centres for five primitive electrical states at 1, 5, and 15 min. Candidate geometries were fitted, selected, and calibrated on chronologically separated complete-orbit blocks, and the final evaluation comprised 25,278 forecast origins from the chronologically subsequent July 2023 telemetry. Across three random-seed runs, the task-aware selector chose a joint box, whereas a residual-volume control selected the sample-covariance ellipsoid. Orbit-balanced primitive-state joint coverage was 0.892 (95% complete-orbit bootstrap confidence interval [CI], 0.883\u20130.899) at the 90% nominal level and 0.947 (95% CI, 0.943\u20130.952) at the 95% nominal level. At 90% and 95%, simultaneous coverage of both power channels across all horizons was 0.913 and 0.957. Relative to residual-volume selection, the task-aware method reduced normalized power interval score by 34.3% and 30.3%; the paired absolute reductions were 1.522 (95% CI, 1.505\u20131.540) and 1.552 (95% CI, 1.534\u20131.570). Power envelopes were computed from synchronized primitive current and bus-voltage sets. For the selected non-negative box, zero algebraic gap and full interval-image containment follow by construction; the empirical analyses quantify coverage and sharpness. The results demonstrate task-aware geometry selection for BUPT-1 multi-horizon power monitoring.<\/jats:p>","DOI":"10.1371\/journal.pone.0360910","type":"journal-article","created":{"date-parts":[[2026,10,13]],"date-time":"2026-10-13T17:32:26Z","timestamp":1791912746000},"page":"e0360910","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Task-aware conformal power envelopes for multi-horizon spacecraft monitoring"],"prefix":"10.1371","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-8206-6921","authenticated-orcid":true,"given":"Nan","family":"Lu","sequence":"first","affiliation":[{"name":"Northwestern Polytechnical University","place":["Xi\u2019an, China"],"department":["School of Computer Science"]},{"name":"Northwestern Polytechnical University","place":["Ningbo, China"],"department":["Ningbo Institute"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lehan","family":"Cui","sequence":"additional","affiliation":[{"name":"Northwestern Polytechnical University","place":["Xi\u2019an, China"],"department":["School of Computer Science"]},{"name":"Northwestern Polytechnical University","place":["Ningbo, China"],"department":["Ningbo Institute"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinian","family":"Zhi","sequence":"additional","affiliation":[{"name":"Northwestern Polytechnical University","place":["Xi\u2019an, China"],"department":["School of Computer Science"]},{"name":"Northwestern Polytechnical University","place":["Ningbo, China"],"department":["Ningbo Institute"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2026,10,13]]},"reference":[{"key":"pone.0360910.ref001","doi-asserted-by":"crossref","unstructured":"Xing R, Xu M, Zhou A, Li Q, Zhang Y, Qian F, et al.
