| São Tomé and Príncipe, Democratic Republic of | INE São Tomé and Príncipe | 2021-11-01 | confirmed | STP.CPI_INESTP_B14_*_INDEX.M | 2026-10-11 | Most of a source disappears for one month |
| INE-STP's complete 2021 CPI catalogue contains monthly folders only from January through October. The next annual workbook publishes December 2021 in its previous-December comparison column, establishing a single missing month rather than a parser or identity collapse. All 128 detailed index series resume with the same codes. November 2021 is therefore an exact, finite, source-published catalogue gap and is preserved without interpolation. | ||||||

| The complete INE-STP annual detail catalogue was archived and each flagged cell is present in the official workbook selected for its year. December is taken from the following year's newer comparison column, so the January steps are within one official publication rather than joins between vintages. Headline and division histories retain their separate consolidated source, and the 2014=100 identity is unchanged. INE-STP publishes no category-level rate or note that distinguishes genuine price volatility from a category-only correction or discontinuity. Retain the official values and warn rather than smoothing them or inventing a private base link. | ||||||
