*	test: expect totaln increment on Simple8 failure path	Craig Jennings	2026-04-29	1	-4/+5
\| \| \| \|	The failure-path assertion in the totaln test now expects the count to increment on both success and failure, matching SM2 and SM5. The updated test goes red against the current source. The source fix follows in the next commit.
*	test: add Simple8 scheduler tests	Craig Jennings	2026-04-29	1	-0/+303
	The Simple8 algorithm at org-drill-determine-next-interval-simple8 had no direct test coverage, completing the trio after SM2 (37 tests) and SM5 (32 tests, just landed). Adds a per-function test file with 34 tests across Normal, Boundary, Error, algorithm-verification, and helper-specific categories. Simple8-specific surface gets dedicated coverage. The function returns a 6-element list (not 7 like SM2/SM5) and recomputes ease from meanq each call rather than carrying an EF parameter through. Failure does not increment totaln (different from SM2/SM5, which always increment). The four delta-days configurations (nil, positive × flag, negative × flag) each take a distinct code path, including a late-review use-n adjustment that SM5 doesn't have. The three pure-math helpers (simple8-first-interval, simple8-interval-factor, simple8-quality->ease) get five direct tests so polynomial-coefficient typos can't drift silently. All 34 pass on first run as characterization. Full suite at 214 of 214 (was 180, +34).
