    Provenance

    Every number here, and what re-derives it

    This site is not allowed to state a figure it cannot re-derive from the codebase. The build fails if it tries.

    That rule has teeth: an earlier draft claimed one product was the only one present in every lifecycle phase, and the check that enforces this refused it — a second product was too. The claim was corrected before anyone outside read it. There are currently 253 such checks across the estate.

    122ontology classes graded against ISBEGO

    Each grading also records the rule or model that produced it and a confidence level.

    What is deliberately not here

    • No outcome percentages. This site used to carry four — 85% less tracing time, 60% faster delivery, 95% better risk identification, 40% fewer overruns. Nothing measured any of them: no engagement, no method, no date. They were removed rather than sourced, because an unattributed percentage is what makes a reader stop believing the rest of the page.
    • No uptime SLA and no price list. Neither exists. An availability figure is a contractual commitment, not an adjective.
    • No comparison to other tools. We have not run one. The figures above are what this estate contains; what anyone else contains is not ours to state.
