[NOTICKET] feat(trend,forecast): row count per period and stub flag (P0-8)
- Each trend point and forecast history point now carries `n` (rows) and `stub` - A stub has fewer rows than half the median non-empty period (needs >= 3 periods); empty periods are not stubs - analyze_trend leaves stubs out of first/last, direction, slope and R^2, with a caveat naming them; it falls back to all periods if every one is a stub - analyze_forecast still fits every period but caveats a thin last actual period - IPR OB LOADER (Sep 9 rows vs 63-66): sum(mtbs) "down" -> "up" (R^2 0.01 -> 0.91); mean(pa) last 99.95 (Sep) -> 92.45 (Jul) - Reported by Rifqi (audit P0-8, decision D4) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>50cae40 -
[NOTICKET] fix(trend,forecast): a period with no rows stays empty (P0-8)
- resample().agg("sum") turned a month with no rows into 0: the trend read it as a collapse and the forecast fitted it as a real value - New temporal._resample(): sum uses min_count=1, so an empty period is None; count keeps 0 (zero events is the true count); other aggs were already None - analyze_forecast uses the same helper, so the empty month is interpolated for the fit - Example (April empty): trend R^2 0.06 -> 0.90, forecast no longer dips after "April 0" - Chart already draws None as a gap; the report table shows it as a dash - Reported by Rifqi (audit P0-8, decision D4) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>f28898b
