PURPOSE
------------------------------------------------------------

Developer-only Codex context source file.

This file is stored in:

    _00_Documentation/00_Sources

and may be referenced by local context indexes under:

    _00_Documentation/01_CONTEXT_Development_Only


============================================================
REPORTING RULE
============================================================

This file must not be mentioned in control-plane reports unless
explicitly requested.

If explicit reference is requested, use the alias:

    CODEX_DEV


============================================================
EXECUTION INSULATION RULE
============================================================

This file is development context only.

It may be used when:

    - writing artifacts
    - rewriting artifacts
    - evaluating artifacts

It must not be used to:

    - execute OPERAE
    - simulate OPERAE
    - infer missing OPERA behavior
    - replace loaded artifact content
    - act as runtime deployment context

Rationale:

    This file is not deployment context. OPERA execution relying
    on it would tie runtime behavior to the developer environment
    and make bug tracking non-reproducible.

CONTENT
============================================================

STACK-TO-ARS-BREVIS CONTEXT NOTES
------------------------------------------------------------

Stack A:

    Stack A refers to absolute principles.

    These are described in Ars Brevis, Chapters 2, 3, and 4,
    especially the First Figure described in Chapter 2.

------------------------------------------------------------

Stack T:

    Stack T refers to relative principles.

    These are also described in Ars Brevis, Chapters 2, 3, and 4,
    especially the Second Figure described in Chapter 2.

------------------------------------------------------------

Stack D:

    Stack D refers to a unified regimen of principles containing
    both absolute and relative principles together.

    This is the main concern of Ars Brevis, Chapter 3.

------------------------------------------------------------

Stack E:

    Stack E refers to Questions and Rules, the main logical
    operators of the Ars.

    It is described in Ars Brevis, Chapter 5, "Rules".

    It is not grounded in the chapter named after "questions".
    The chapter about "questions" must not be read as referring
    to this regimen.

    Questions are Rules rendered in interrogative form.

    Example:

        Rule of Possibility rendered in question form:
            UTRUM? / Whether?

    Alias discipline:

        E  = whole stack
        Q  = interrogative focus
        R  = logical gating / rule focus
        QR = valid alias
        EQ = valid alias when E-stack + interrogative focus is meant
        ER = valid alias when E-stack + rule focus is meant
        EQR = valid alias when whole E-stack with Q/R distinction is meant

------------------------------------------------------------

Stack F:

    Stack F refers to the Tabula.

    It is described in Ars Brevis, Chapter 6.

------------------------------------------------------------

Stack G:

    Stack G refers to the Third Figure.

    It is described in Ars Brevis, Chapters 2 and 7.

    Chapter 2 defines the form and is mostly source for:

        ROTA G
        TENET G

    Chapter 7 describes what is intended in:

        OPERA G
        TENET G

------------------------------------------------------------

Stack H:

    Stack H refers to the Fourth Figure.

    It is described in Ars Brevis, Chapters 2 and 8.

    Chapter 2 defines the form and is mostly source for:

        ROTA H
        TENET H

    Chapter 8 describes what is intended in:

        OPERA H
        TENET H

------------------------------------------------------------

Stack I:

    Stack I refers to the required discipline when mixing
    principles and rules.

    It is described in Ars Brevis, Chapter 9.

    Stack I regulates:

        OPERA F
        OPERA H
        OPERA G

------------------------------------------------------------

Stack S/K:

    Stack S/K refers to a Categorimata of subjects within the Ars.

    Only TENET K bears K in its name.

    The other artifacts are under S.

    The Ars Brevis chapter is Chapter 9, but the subject
    categorimata has implications across all stacks.
