New flag_level_outliers(): a third inspection layer that compares each token’s overall level (its median f0, in semitones) against other tokens of the same speaker and same tone using a robust modified z-score (median/MAD; Iglewicz & Hoaglin 1993, cutoff 3.5). It flags smoothly shifted contours — e.g. a low-tone token mis-tracked up into the mid-tone band — that the pooled max/min check and the sample-level jump check both miss. Surfaced through inspect_f0() (new level_threshold and min_tokens arguments, level too high / level too low notes) and the Inspect tab.
The "norm" (normalised-time) option was removed from time_unit in flag_pitch_jumps(), inspect_f0(), and the Inspect tab: the rate-of- change thresholds are physiological (ST per 10 ms) and have no meaning once real time is discarded. Inspection runs on real-time data (s / ms).
Inspect-tab guide rewritten around three complementary layers, and the “Pitch-tracking quality check” workflow now marks Normalise as optional (inspection runs on raw f0).

flag_pitch_jumps() (and therefore inspect_f0() and the Inspect tab): when a sample-to-sample jump is detected, the flag is now placed on whichever side of the jump is farther from the token’s median f0, rather than always on the landing sample. This correctly identifies the artefact whether it sits at the start or the end of a sequence (e.g. an octave doubling on the first frame of a token, which the previous landing-only logic mis-flagged).
Carryover now walks both forward AND backward from each flagged sample, so artefact runs that begin or end the token are extended in both directions.
Inspect-tab guide text and flag_pitch_jumps()’s function docs describe the new median-aware logic as an adaptation of the rate-of-change + carryover approach in Steffman & Cole (2022).
Package skin only at this stage: the Shiny app continues to run unchanged. Standalone analytical functions (normalise_f0(), fit_gca(), fit_gamm(), contour_to_chao(), …) will be extracted in subsequent releases.
