*Archive notice (2026-10-10, reconciled 2026-11-01).* The active proof stack is Agda (`proofs/agda/`, `--safe --without-K`, zero postulates) + Z3 as a bounded-check solver + the Idris 2 ABI. Coq, Lean 4, Isabelle/HOL and Mizar now live under `archive/proofs/`; paths below of the form `proofs/coq/…` / `proofs/lean4/…` refer to the *archived* trees (`archive/proofs/coq/…` etc.), and counts such as "115 Qed / 61 Axioms" are *historical* figures of those archived trees. The canonical active-vs-archived proof-status table is link:PROOF-STATUS.adoc[PROOF-STATUS.adoc], which also records the estate proof grades (mathesis `estate-mathematical-architecture` §5) and the closed ledger vocabulary of `hyperpolymath/standards` (`proven` / `proven-with-postulates` / `tested-only` / `argued` / `open`): the active Agda proofs are `proven` at **Grade 3** (local strict-flag check, no independent-foundation translation), the Z3 bounded checks are `tested-only`, and OND-6 is `open`.

Complete the active-versus-archived rewrite.

The archive notice is correct, but the claim map still says proofs/verify-all-provers.sh orchestrates verification, CI gates Coq and Lean 4, and Z3, Isabelle, and Mizar are not run. The active workflow now runs Agda, Z3, and Idris 2. Mark this whole claim historical or rewrite it for the active stack. (raw.githubusercontent.com)

Update the claim map in EXPLAINME.adoc so its verification and CI descriptions
match the active Agda, Z3, and Idris 2 workflow; mark the Coq, Lean 4, Isabelle,
and Mizar claims as historical or remove them from the active workflow
description. Keep the archive notice consistent with the revised claim map.

The two pillars are logically independent (a proved theorem, with witnesses).
____

How this is implemented::
The independence theorem is proved in Coq, anchored to the core `is_CNO` definition. Witnesses demonstrating that CNO does not entail OND and OND does not entail CNO are constructed.
How this was implemented::
The independence theorem was proved in Coq (`archive/proofs/coq/ond/OND.v`, anchored to the core `is_CNO` definition, with witnesses that CNO does not entail OND and OND does not entail CNO); the active Agda `OND.agda` carries the same obligation zero-postulate.

Caveat::
None currently known for the independence proof itself. However, the *coupling dial* between them (connecting a thing to the trace it casts) is explicitly framing, not theorem.

____OND obligations OND-1..5 are proved with zero postulates in Agda (`proofs/agda/OND.agda`, `--safe --without-K`)____

How this is implemented::
`link:proofs/coq/ond/OND.v[]` contains the proofs. CI verifies that the global context is closed (no axioms admitted). Mirrored in Lean 4, Agda, and Z3.
`link:proofs/agda/OND.agda[]` contains the active proofs; CI (`proofs.yml`, `agda` job) type-checks all four Agda modules under `--safe --without-K`. The historical Coq proof (`archive/proofs/coq/ond/OND.v`, every theorem `Closed under the global context`) and the Lean 4 mirror are archived; Z3 confirms the bounded instances (`proofs/z3/ond/OND_checks.smt2`, expect-annotated).

Caveat::
OND proofs are axiom-free *relative to the declared observation model `O`*. The choice of `O` is a proof input, not a proof output. If `O` omits a real-world observable channel (e.g., power analysis), the OND proof is sound but physically incomplete. The residue list in `link:proofs/residue/[]` records this gap.

== Canonical proof-status reconciliation (2026-11-01)

This table is the *single canonical statement* of proof status in this
repository. Where older prose (README, EXPLAINME, ROADMAP, `docs/*`) quotes
counts such as "115 Qed / 0 Admitted / 61 Axioms", those figures describe
the *archived* Coq tree under `archive/proofs/coq/` only. They are
historical, they are not active, and they are **not estate-wide proof-status
ground truth** — see "Role of this repository" below.

*Grading scheme.* Statuses below use the closed proof-ledger vocabulary of
`hyperpolymath/standards` (`3-practice/PROOF-POLICY.adoc` §5 and
`docs/README-EXPLAINME-STANDARD.adoc` §5): `proven`, `proven-with-postulates`,
`tested-only`, `argued`, `open` — recorded exactly, never flattened into a
percentage. Estate grades follow mathesis's `estate-mathematical-architecture`
§5–6: **Grade 3** = type-checks locally in Agda under strict flags but not yet
translated to an independent foundational system; **Grade 2i/2ii** =
translation to one/two independent foundations (2ii requires a non-DTT
second system, e.g. Isabelle/HOL); **Grade 1** = headless CI via verified
checker APIs. Verification receipts are tied to commit hashes; superseded
claims are marked historical, not silently dropped, and axiom dependence
(`Print Assumptions` / `#print axioms`) is tracked per row.

P1 Badge Do not count the surrogate null predicate as OND-3

When the active Agda stack is used as the canonical receipt, this overstates its coverage of OND-3: proofs/agda/OND.agda never imports CNO and instead defines a separate is-null : Op → Set; OND3-cno-ond-independent proves independence from that local predicate, not from the active pillar's CNO.IsCNO. The roadmap defines OND-3 as depending on the existing is_CNO, so either connect the Agda theorem to CNO.IsCNO or stop claiming that the active stack discharges all of OND-1..5.

P2 Badge Describe the Z3 model's actual unbounded scope

The canonical scope description calls this a finite observation model, but proofs/z3/ond/OND_checks.smt2 declares the secrets, public input, output, and timing values as unconstrained Ints and adds no finite-domain bounds; it checks three fixed operation formulas rather than a finite set of bounded programs. Consumers of this proof ledger therefore cannot tell what was actually tested, so describe it as a fixed symbolic SMT model or add the stated bounds.

Pin the Z3 receipt to the checked source revision.

The grading scheme requires receipts tied to commit hashes, but this entry records a working tree “over bb46232”. It does not identify the exact source that produced the result. Record the full checked-tree SHA or an immutable content hash. The repository records bb46232 and ad66f2c as separate commits. (github.com)

* *Agda, Idris 2, Coq, Lean 4, Isabelle/HOL, Mizar, Rust/Creusot — NOT
RUNNABLE HERE.* The sandbox egress allowlist (github.com, codeload.github.com,
api.github.com, registry.npmjs.org, pypi.org, files.pythonhosted.org) blocks
apt mirrors, static.rust-lang.org, opam.ocaml.org and Hackage, so none of
these toolchains can be installed in this session. Per standards
`3-practice/PROOF-POLICY.adoc` §6, a leg that cannot run is *said so*, never
reported as passing: the Agda `--safe --without-K` checks, the
`--cubical-compatible` recheck (open obligation, above), and the Idris 2 ABI
build remain CI receipts (`proofs.yml`: `agda`, `z3`, `idris` jobs), not
sandbox receipts. Archived provers stay archived and unexecuted.

=== Role of this repository (consumer, not estate-wide ground truth)

absolute-zero is a *consumer and domain formalisation*: it applies standard
results (Landauer 1961, Bennett 1973, the non-interference literature,
category theory) to its own CNO/OND domain concepts. Its historical prover
counts (above) are evidence about its own archived trees only, and must not
be cited as proof status for any other repository.

*Cross-repo note (2026-11-01).* `epistemic-types` (at `5422cd5`) is an
*independent* proof library with **no dependency on absolute-zero**. Any
cross-repo claim must therefore name the exact theorem, its scope, and its
assumptions (e.g. "OND-1..5, `proven`, Grade 3, Agda `--safe --without-K`,
relative to a declared `O`") — never a bare count imported from this repo.
Mathesis (the estate mathematical knowledge commons) may *catalogue* these
receipts and grades, but per its own architecture the original repositories
remain the sovereign owners of their mathematics; this file is the local
proof-status record of record.

[NOTE]
====
The per-prover sections below this table are *historical* for Coq, Lean 4,
Isabelle/HOL and Mizar (archived 2026-10-10) and *active* only for Agda, Z3
(bounded) and the Idris 2 ABI. They are kept for the record; the table above
is the canonical summary.
