Resolve a single duty day from raw clock punches and a shift definition. Returns a structured DayResult with status, worked minutes, lateness, early-out, overtime, overnight handling, breaks-deducted minutes, data-integrity flags, and the resolved in/out segments.

Resolve a sequence of duty days (a week, a pay period, a month). Returns per-day DayResult entries; optionally include an aggregated PeriodSummary with attendance rate and flag counts.

Analyse meal & rest period compliance for a duty day under a jurisdiction rule pack. v0.1 ships the California pack (Labor Code §§ 226.7, 512; IWC wage orders). Returns per-meal/rest analysis, premium hours owed at the regular rate, waiver issues, and rebuttable-presumption risk per Donohue v. AMN.

Produce a rounded view of a resolved day's worked & overtime minutes without losing the exact-minute result. Useful for the California-style 'exact-minute is the baseline; rounding must be provably neutral' pattern — keep both views and compare across populations.

Generate a rotating roster from a built-in pattern ('2-2-3', '4-on-4-off', 'dupont', 'pitman') or a custom day cycle. Returns one assignment per calendar date with shift label and HH:MM window, or null on rest days.

List bundled jurisdiction rule packs (meal/rest compliance). Returns each pack with id, human label, citation source, and full rule definitions.

Run a wage-and-hour compliance audit across multiple days. For each day, resolves attendance and evaluates meal/rest compliance under the chosen jurisdiction rule pack. Returns per-day breakdown plus period totals: hours of premium owed (meal + rest), days at risk, days with rebuttable-presumption exposure, and a flag-count heatmap. Use this for monthly payroll review, pre-audit triage, or a manager dashboard.

Triage raw clock punches before trusting them: count, sort, dedup, surface duplicates / odd-punch counts / round-number bias, report longest and shortest gaps, and (when an expected shift is provided) flag punches that fall outside it. Returns a recommendation: 'usable', 'review', or 'reject'.
