[generated] kernel theorem CReal.integral_by_parts (creal prelude, axiom-free, prose not curated)

Identifier: F:creal-integral-by-parts
Proof route: kernel-lean
External status: Not recorded
Axiom footprint: Empty

Recorded description

MECHANICALLY GENERATED, UNREVIEWED PROSE -- this sentence deliberately makes NO mathematical characterisation of the theorem. What is asserted, and all that is asserted, is this: the kernel declaration `CReal.integral_by_parts` is a `Declaration::Theorem` admitted into the environment by `build_creal_prelude` through the trusted `Kernel::add_declaration` gate, which re-derives its type from its proof term; its type is recorded verbatim in `formal.statement`; and its axiom footprint, as computed by `Kernel::axiom_footprint`, is empty. The authoritative content of this fact is `formal.statement`. A human-readable characterisation of what CReal.integral_by_parts SAYS has not been supplied, because a generator cannot supply one honestly -- see `notes`.

Evidence

kernel-CReal.integral_by_parts

Kind: kernel-term
Status: checked

Supports: CReal.integral_by_parts is admitted by the trusted kernel gate with the type recorded in formal.statement.

Checker command

cargo run -q --release -p axeyum-lean-kernel --example theorem_dependency_inventory -- CReal.integral_by_parts 2>/dev/null | grep -cE '^CReal\.integral_by_parts[[:space:]]'

Evidence notes

Two independent failure modes, so the exit status depends on the finding rather than on the run completing: theorem_dependency_inventory exits non-zero when a NAMED filter matches nothing, and grep -c exits 1 printing 0 when the anchored line is absent. Anchored with [[:space:]], never \t -- in a scripted (GNU) grep \t is a literal t. grep -c rather than grep -q, which would SIGPIPE the producer under pipefail. --release is MANDATORY: this tool builds creal/complex/cpoint, which overflow the default debug thread stack.

footprint-CReal.integral_by_parts

Kind: exhaustive-enumeration
Status: checked

Supports: axiom_footprint: [] -- the creal prelude's trusted surface is empty, which bounds CReal.integral_by_parts.

Checker command

cargo run -q --release -p axeyum-lean-kernel --example nat_axiom_inventory -- --include-constructed --require-axiom-free creal

Evidence notes

--require-axiom-free exits non-zero when the named prelude's trusted surface (Axiom + Opaque + Quotient) is not empty, and errors rather than silently passing for a prelude the run never built. A declaration cannot depend on a trusted declaration the environment does not contain, so an empty creal surface bounds every declaration in it, including CReal.integral_by_parts. This is a whole-prelude bound, not a per-declaration measurement; the per-declaration figure is the footprint column of kernel_declaration_projection, measured 0 for this row.
