docs: proof review against PROOF-POLICY; proof ledger; plan correction - #787
This follows the merged completion plan, #786. I re-ran every prover that could be installed, and judged each proof against metadatastician/standards3-practice/PROOF-POLICY.adoc at commit 9bdf864.
What changed
Proof ledger, in docs/EXPLAINME.adoc. The README-EXPLAINME standard requires one whenever a repo claims proofs, and this repo had none. It is keyed to the obligation IDs in docs/PROOF-NEEDS.adoc and has 22 rows: 7 proven, all of them about models rather than the shipped code; 13 open; and 2 argued. No theory theorem has a proof witness grade, because none has an Agda source.
Solo core status.docs/SOUNDNESS.adoc and docs/PROOF-NEEDS.adoc still said the Solo core's progress and preservation were ?todo. Both now check under Idris2 0.7.0 and are total. That was a local check; no CI job runs it yet.
PROOF-NEEDS caveats. P-3, P-4 and the K-1 real-lift text now say they hold for models only. F-5 records the real render_ty counterexample and stays open.
Plan proof route. The completion plan's proof route was Coq-first. It is now aligned with the policy: theory goes in Agda with Rocq and Lean rechecks, and engineering goes in Idris2 or under a recorded §4 exception. There is a new section 5.0 and corrected rungs.
Plan findings and rulings. Workflow W7 is corrected. The plan also gains the verified per-repo results, new cross-repo items, and owner questions 16 to 19 with the owner's rulings of 2026-11-09.
Idris2 0.8.0 results and provisioning fix (19084c8).
typed-wasm passes tools/check-kernel-proofs.sh in full under its pinned Idris2 0.8.0 (15a3e4e). The plan's Region.idr item is closed.
januskey and absolute-zero type-check under the 0.8.0 release.
New estate item: the Idris2 repos check against three different compilers. typed-wasm uses the v0.8.0 tag, januskey and absolute-zero use a pack image built from Idris2 main, and anytype uses 0.7.0.
The W0 recipe now passes PREFIX to make bootstrap as well as to make install. Without that, Idris2 type-checks but cannot run programs, and still exits 0.
New holes
H20.Face.render_ty is not injective. On the Js face, List[Option[Int]] and Option[List[Int]] both render as List[Int] | null; on Cafe both render as List[Int]?. I observed this by calling the built library. The Coq F-5 theorem proves the opposite, but for a model that differs from the code.
H21. The Coq proof gate covers only 96 of the 137 assertions. A planted Admitted false lemma and a planted Axiom False both passed a replica of the gate.
H22. The 23 staged Agda files under proposals/ pass the canonical flags, but nothing runs them. tools/check-proofs.sh --agda reports SKIP when its environment variables are unset.
Proof review results
Coq. All 20 files build under Coq 8.18, and all 137 assertions are closed under the global context. Several headline theorems hold by definition: P3 borrow soundness, F3, F4, F1 same_cube, and QttTyping.usage_soundness. The Real* models differ from lib/codegen.ml.
Idris2 Solo core. It checks, and progress and preservation are total.
Lean, installed with the owner's approval from releases.lean-lang.org.
tropical-types builds all 20 modules at its 4.13.0 pin. Its 334 theorems use no sorry, no Mathlib and no Classical.choice.
occupancy's stackcert does not compile at its 4.15.0 pin.
This repo's copy of the tropical file compiles at 4.13.0.
Not re-run. CI's Coq 8.20.1 was not re-run.
Checks
bash tools/check-doc-truthing.sh: OK
bash tools/check-soundness-ledger.sh: all 5 properties hold. It ran on deepened history.
asciidoctor --failure-level=WARN on all four files: clean
Re-ran every prover that could be installed and judged each proof
against metadatastician/standards 3-practice/PROOF-POLICY.adoc
(9bdf864).
- Add a proof ledger to docs/EXPLAINME.adoc in the standard's closed
vocabulary: 15 obligations, 7 proven (all about models), 7 open,
1 argued. No theory theorem has a proof witness grade, because none
has an Agda source.
- Correct the stale Solo-core status in SOUNDNESS and PROOF-NEEDS:
progress and preservation check under Idris2 0.7.0 and are total
(local check; not yet CI-gated).
- Correct the completion plan's proof route to the policy: theory in
Agda with Rocq and Lean rechecks, engineering in Idris2 or a recorded
section 4 exception. Add section 5.0, the verified per-repo results,
holes H20 (Face.render_ty is not injective, observed on the built
library), H21 (the Coq gate passes planted admits outside its cone)
and H22 (the staged Agda is unchecked; check-proofs skips silently),
new cross-repo items, and owner questions 16 to 19.
doc-truthing and the soundness ledger gate pass; all four files render
without warnings.

Added a proof ledger summarising 15 obligations, their status, verification methods and limitations, alongside records of Coq and Idris2 checks.
Updated the documented Solo model results to record locally checked progress and preservation proofs, while clarifying that these results are not yet checked by CI and do not establish properties of shipped code.
Revised the proof plan, workflow guidance, survey findings and open questions, including newly recorded proof gaps and remaining work.
The documentation records proof-review results across estate repositories, adds holes H20–H22, and revises proof policy, prover routes, gates and workflow guidance. It also adds a proof ledger and updates the reported status and scope of the Solo model’s progress and preservation proofs.
Changes: Proof review and policy
Layer / File(s)
Summary
Estate proof findings and holes docs/COMPLETION-PLAN.adoc
The plan replaces earlier status claims with reported prover and fixture results across repositories. It adds findings and holes H20–H22.
Proof policy and prover routes docs/COMPLETION-PLAN.adoc
The plan distinguishes theory and engineering proof routes, updates prover assignments, and classifies solver results as TESTED rather than PROVEN.
Proof gates and estate follow-up docs/COMPLETION-PLAN.adoc
The plan broadens proof gates, revises workflow W7, and adds estate follow-up items and owner questions.
Proof ledger and Solo model status docs/EXPLAINME.adoc, docs/PROOF-NEEDS.adoc, docs/SOUNDNESS.adoc
The ledger lists 15 obligations, check receipts and trust boundaries. The Solo model documents report local Idris2 checks of progress and preservation, and state that these checks are not gated in CI.
hyperpolymath/affinescript#786: This PR revises the completion plan introduced by #786, including its proof routes and workflow W7.

Review comments at @docs/COMPLETION-PLAN.adoc:
- Line 859: Update the Idris2 build instructions so both make commands run from
within the cloned Idris2 repository, not the AffineScript root. Preserve the
existing installation steps and note that Idris2 0.8.0 remains unverified in a
sandbox.
- Line 859: Update the workflow setup associated with the Idris2 installation to
add /opt/idris2/bin to PATH and ensure subsequent workflow agents inherit that
environment, so direct proof checks and tools/check-proofs.sh can locate idris2.
- Line 859: Update the P3 and F2 toolchain statuses to reflect that W0
provisions Idris2 0.7.0, and correct F2’s claim that only Z3 can ship to account
for the recorded anytype CLI checks. Retain the package-path fix and
partial-coverage limitations, and distinguish the available 0.7.0 toolchain from
the unverified Idris2 0.8.0 version pinned by typed-wasm.
- Line 931: Update the Solo work assignment in the plan to include a checked
Rocq recheck of Solo progress and preservation for the quantitative calculus,
alongside the Agda port and statement comparison. Do not treat Rocq proofs for
the non-quantitative calculus as satisfying this requirement; make clear that
the required Rocq leg must cover the Solo calculus before Solo can reach PWG-2i.
- Around line 223-225: Update the SOUNDNESS.adoc ledger milestone and the W1/M1
completion criteria to require entries for H20–H22, so those milestones cannot
complete while these holes are omitted. Add suitable test anchors for H20’s
nested Option rendering on Js and Cafe, H21’s proof-gate handling of assertions
outside theorem dependency cones and reruns when lib/*.ml changes, and H22’s
Agda checks, including missing environment configuration and pinned echo-types
revision.
- Line 858: Update the W0 gate in the Gates entry to check that each Agda
entrypoint’s cubical mode is explicitly identified and covered by a reviewed
profile; keep the cubical-profile obligation open until that review is recorded,
rather than treating success with the specified flags as sufficient.
- Line 932: Update the Coq gate for the H21 work in formal/ to independently
reject standalone axioms, including unused declarations omitted from the
generated assertion list. Keep the existing Print Assumptions check and add a
negative test proving an unused declaration such as bad : False causes the gate
to fail.
Review comments at @docs/EXPLAINME.adoc:
- Line 109: Update the proof inventory’s RealCompile description to identify it
explicitly as a model, not the shipped compiler, and state that its integers are
unbounded rather than i32. Clarify the proof scope so it does not imply that the
shipped compiler or i32 behaviour is proved.
- Line 175: Update the F-5 row and sequencing table in PROOF-NEEDS.adoc to
reflect the nested-list collision: injectivity of the real Face.render_ty
remains open, so do not mark F-5 non-collision complete for wave 1.
- Around line 81-83: Reconcile the proof-obligation ledger in EXPLAINME with the
inventory in PROOF-NEEDS.adoc, adding omitted obligations including P-5, P-7 and
F-6. Update the census to reflect the complete ledger and use the closed status
vocabulary defined by the standard.
Review comments at @docs/PROOF-NEEDS.adoc:
- Line 153: Update the P-2 entry in the proof-needs documentation to mark the
Solo proofs complete, reflecting that Soundness.idr defines Step and all three
proofs. Keep any broader work that remains partial clearly distinguished from
the completed Solo task.

Included review availability: This review used your included allowance. Your plan provides up to 1 included review per hour; 0 remain after this review.
Questions 16-19 and the next-phase choice are ruled: rewrite the
definitional theorems first; Agda sources split by topic (semiring laws
in resource-algebra, calculus soundness in formal/agda); Idris2 0.8.0
and Lean installs approved with section 6 deviation records; W1 first.
With Lean installed from releases.lean-lang.org (digests recorded):
tropical-types builds 20/20 at its 4.13.0 pin, and its 334 theorems use
no sorry, Mathlib or Classical.choice (102 use propext or Quot.sound);
occupancy's stackcert core does not compile at its 4.15.0 pin; the
AffineScript copy of the tropical file compiles at 4.13.0.

- Proof ledger now keyed to every PROOF-NEEDS obligation: 22 rows, 7
proven (models only), 13 open, 2 argued (adds P-5, P-7, P-8, P-10,
F-2, F-6, F-7); prose-proof paths corrected to .adoc.
- PROOF-NEEDS: P-2 marked mechanized for the Solo model; caveats on
P-3, P-4 and the K-1 real-lift text (models, unbounded Z, not i32);
F-5 records the real render_ty counterexample and stays open.
- Plan: H20-H22 added to M1, W1 and section 3 with test anchors;
W0 build steps cd into the Idris2 clone and put it on PATH; cubical
pragma modules need a reviewed profile; the Coq gate must also scan
for unused axioms; the Solo core needs its own Rocq recheck; the
anytype and P3/F2 statuses reflect that Idris2 0.7.0 is provisionable.

- typed-wasm passes tools/check-kernel-proofs.sh in full under the
pinned Idris2 0.8.0 (15a3e4e): 33 modules, 13 rejections, 197-row
explorer, 269 table equalities, 4 negative controls. Region.idr:179
was a 0.7.0-only incompatibility; the ledger item is closed.
- januskey and absolute-zero type-check under the 0.8.0 release;
januskey's 3 reject fixtures are refused for the expected reason and
a planted well-typed fixture fails its script. Their CI pins an
idris2-pack image built from Idris2 main (6ca00e72...), not the
v0.8.0 tag; that image was not run. New estate item: the Idris2 repos
check against three different compilers.
- W0 recipe: PREFIX must go to make bootstrap as well as make install,
or the install type-checks but cannot run programs, and Idris2 still
exits 0. The exit-code rule now covers INTERNAL ERROR and Exception.
