Wording changes never bump the version; a term's reviewed date moves instead. Minor
releases add a term or a switch without moving a default. Major releases change a
default or a locked choice, which restates numbers computed under the previous version — so a
citation such as sof-v1.0 always names a specific ruleset.
- v1.0 Major — restates numbers
- Initial public release: seventeen terms covering customer-level revenue metrics — the measured unit through the register.
- Locked defaults: comped customers excluded; usage included in NRR; monthly-average FX flow rates; the five-movement taxonomy; the seven-value revenue-type enumeration; ACV bands at 5K / 25K / 100K / 500K.
- Default NRR variant is the monthly-cohort compounded trailing twelve months; the year-over-year snapshot and quarterly annualized variants are defined and computed alongside.
- Reactivation window default of three months; right-censored gaps governed by a separate trailing-gap policy.
