- Add testUpper, testLower, testHarm params to gsDesign(), gsSurv(), gsSurvCalendar()
- gsApplyTestBounds recomputes bounds with modified spending, preserving exact alpha
- gsModifySpend flattens cumulative spending at inactive analyses
- gsBoundSummary and print.gsDesign mask inactive bounds as NA
- Relax gsBound/gsBound1 to allow 0 final spend (C code returns +/-EXTREMEZ)
- Add SelectiveBoundTesting vignette with Type I error preservation examples
- 114 unit tests for selective bounds; full suite 2573 pass, 0 fail
- R CMD check: 0 errors, 0 warnings, 1 note
