proofs: ground-truth audit, Lean vacuity fix, Agda under the estate invocation, archive Isabelle/Mizar, Z3 fixes - #223
This PR re-runs every prover leg on main (2d798b8) against the estate proof policy (hyperpolymath/standards3-practice/PROOF-POLICY.adoc). It then carries out the owner rulings of 2026-11-09, recorded as OD-30 to OD-34 in the route plan. The full record is in docs/audits/2026-11-09-proof-ground-truth.adoc.
Soundness fix: Lean RmdirPrecondition was uninhabited
isEmptyDir checked a path's ancestors instead of its descendants. Because the parent always exists, the precondition could never hold. As a result, every Lean theorem that assumed it was vacuous, including the composition theorems for any sequence containing mkdir or rmdir. The fix is one line.
The new PreconditionWitnesses library proves that each precondition can be satisfied. It also proves that a non-empty directory is rejected. Weakening isEmptyDir to True now breaks the build; I checked this by mutation. CI now builds every Lean library that compiles, not just the default target.
Agda: the theory source, now checked under the estate invocation (OD-30, OD-32)
Removed the funext postulate. Filesystem equality is now pointwise (_≗_); every former funext helper proof was already pointwise inside.
Removed K. Clauses that matched refl on p ≡ p now use fsUpdate-at instead.
Completed IsEmptyDir, which was missing its emptiness field, and added Agda precondition witnesses.
Added All.agda, which imports every module, and a new CI lane, .github/workflows/agda.yml. The lane installs Agda 2.7.0.1 checked against its digest and agda-stdlib v2.2 at a pinned commit, guards against postulates and against modules missing from All.agda, then runs --safe --without-K --cubical-compatible. All 10 modules check.
Isabelle and Mizar archived; Z3 fixed (OD-33)
archive/proofs/ holds both trees with a successor map for all 139 theorems. Every consumer is updated: both Justfiles and both verify scripts.
Z3: filesystem_operations.smt2 assumed each theorem as an axiom before checking it, which is circular. symlink_operations.smt2 never negated a goal. Both now define their operations directly, check that the preconditions are satisfiable, and negate every goal. Each remaining .smt2 file now carries its §4 exception note.

Dedukti transport experiment (OD-32)
docs/experiments/2026-11-09-dedukti-transport/: transporting the Agda proofs to Rocq or Lean does not work today.
Agda2Dedukti has no --cubical-compatible option and predates agda-stdlib 2.x, so it cannot read these modules.
Lambdapi's Rocq export drops rewrite rules, so coqc rejects any proof that relies on a definition computing.
Lambdapi 4.0.0 has no Lean export.
Dedukti itself checks the same encoding.
Review and CI
I addressed the CodeRabbit findings. The one I didn't take (a parent-directory precondition in Lean's rmdir only) is explained on its thread and recorded as Agda spec work.
I fixed both SonarCloud findings in agda.yml.
governance and secret-scanner fail at startup on main too, so they are not from this PR.
Verification (local)
Agda:agda --safe --without-K --cubical-compatible All.agda exits 0, with no postulates.
Lean 4.34.1: all 9 working libraries build, plus model_oracle.
Coq 8.18.0: all 11 files build. A witness that rmdir_precondition can be satisfied is closed under the global context.
Z3:scripts/verify-z3.sh passes all five files.
Idris2 0.8.0: builds under --total, with 2 registered axioms.
Rust:cargo test gives 827 passed, 0 failed, 15 ignored.
Docs and recipes: asciidoctor renders every changed doc with no warnings, and just --list parses both Justfiles.
Not verified
Isabelle and Mizar: not run. Isabelle's distribution server returned 503, and the Mizar installer was not permitted in the session; both are now archived.
Agda2Dedukti: not built, because the session refused to compile an unvetted external repository.
… ground truth
isEmptyDir quantified over ancestors (child.isPrefixOf p) instead of
descendants. The parent always exists, so RmdirPrecondition was
uninhabited and every Lean theorem assuming it was vacuous, including
the composition theorems for any sequence containing mkdir or rmdir.
Flip the prefix test to match the Coq and Isabelle models.
Add PreconditionWitnesses: one inhabitant per operation precondition
plus reversible (.mkdirOp ["a"]) emptyFS, so a future edit that empties
a precondition fails the build. Make CI build every Lean library that
compiles, by name; a bare `lake build` only built FilesystemModel.
Record a re-run of every prover leg against PROOF-POLICY in
docs/audits/2026-11-09-proof-ground-truth.adoc, refresh the
PROOF-NEEDS reproduction block that the mathesis census reads, and
correct the claim that Coq is_empty_dir_dec is an Axiom: it is a
Theorem proved with Classical.classic.

Summary
Summary by CodeRabbit
Bug Fixes
Corrected the empty-directory condition so valid directory-removal cases can be verified.
Tests
Added concrete checks for filesystem operation preconditions and reversibility.
Added automated Agda proof checks and expanded Z3 checks for filesystem operations.
Documentation
Updated proof-status records and audit findings. Agda is identified as the theory source, with Lean and Rocq as recheck systems; Isabelle and Mizar are documented as archived and unchecked.
Chores
Updated the Lean verification workflow to build the listed libraries compatible with Lean 4 v4.34.1.
Removed Isabelle and Mizar from the active build and verification commands.
Changes
Agda and Lean filesystem proofs, build checks and Z3 models are updated. Repository records revise proof-system roles, archive status and reported verification results. A Dedukti transport experiment is also added.
Filesystem proofs and verification
Layer / File(s)
Summary
Agda model, operation proofs and witnesses proofs/agda/*, proofs/lean4/FilesystemModel.lean, proofs/lean4/PreconditionWitnesses.lean
Agda uses pointwise filesystem equality and checks strict descendants in its empty-directory condition. Agda and Lean add operation-precondition witnesses; Lean also adds rmdir negative controls.
Build and validation integration .github/workflows/agda.yml, .github/workflows/rust-cli.yml, Justfile, .machine_readable/contractiles/Justfile, proofs/lean4/lakefile.lean, scripts/*
Agda CI pins its toolchain, runs the coverage check and invokes the safe, without-K and cubical-compatible check. Lean builds named Lake targets. Verification recipes remove Isabelle and Mizar checks.
Z3 models and result checks proofs/z3/*.smt2, scripts/verify-z3.sh
Filesystem and symlink checks use array-based models and scoped queries. Expected result sequences and status notes are updated.
Proof status and policy
Layer / File(s)
Summary
Archive proof trees and update consumers archive/proofs/README.adoc, Justfile, CONTRIBUTING.adoc, ffi/rust/src/*, impl/*, scripts/*
The archive README records successor mappings. Build recipes, validation targets, proof references and generated proof-system lists identify Isabelle and Mizar as archived and unchecked.
Record audit results and proof roles docs/audits/*, PROOF-NEEDS.adoc, CLAUDE.md, EXPLAINME.adoc, REVIEW.adoc, docs/PROOF_HOLES_AUDIT.adoc, docs/plans/*, proofs/*
The records describe toolchains, prover results, proof classifications and revised proof-system roles. They report the Lean predicate correction and Agda’s removal of funext.
Dedukti transport experiment
Layer / File(s)
Summary
Record encoding and export findings docs/experiments/2026-11-09-dedukti-transport/*
The experiment adds a natural-number encoding and documents reported constraints on Agda-to-Dedukti input, Rocq export and Lean support.
hyperpolymath/valence-shell#221: Repairs and audits the Agda proof tree; this change removes funext, adds safe checks and witnesses, and updates the proof status.
hyperpolymath/valence-shell#222: Defines the proof architecture and verifier roles; this change records revised rulings and applies them across proofs, CI, build scripts and audit records.
Merge Risk: Low · up to 519e1
The remaining proof-status wording could mislead readers, but does not block the proof-checking workflow. Correct the summaries and Z3 legend as a bounded follow-up.

Review comments at @CLAUDE.md:
- Line 111: Update the proof-gap summary beginning “2 proof holes remaining” to
make clear that “0 real gaps” refers only to the historical hole count, not the
current state of proof work. Link to the current audit and preserve its reported
oracle/spec mismatch and four Lean libraries that do not build.
Review comments at @PROOF-NEEDS.adoc:
- Line 124: Update the `is_empty_dir_dec` registry entry to list both
`Classical.classic` and `ClassicalEpsilon.constructive_indefinite_description`
as dependencies, while retaining that it is a theorem rather than a custom
axiom.
Review comments at @proofs/lean4/FilesystemModel.lean:
- Line 76: Update RmdirPrecondition to require that the path’s parent exists and
is a directory, so removal is rejected when an ancestor component is a file;
adjust the relevant witness to establish the parent-directory condition.
Review comments at @proofs/lean4/PreconditionWitnesses.lean:
- Around line 23-35: Add a Lean theorem alongside rmdir_pre_inhabited showing
that RmdirPrecondition does not hold for a directory containing a child;
construct a filesystem with that non-empty directory and prove the precondition
cannot be satisfied, so the theorem is checked by the existing CI build.

Owner ruling 2026-11-09: Agda is the theory source of truth here, per
standards PROOF-POLICY §1. Make the tree meet the canonical invocation.
- Remove the funext postulate. Whole-filesystem equalities are now
pointwise (_≗_); every former `funext helper` proof was already
pointwise inside, so no theorem loses content. Composition gets
fsUpdate-cong, applyOp-cong and applySequence-cong.
- Remove K: clauses that matched refl on `p ≡ p` now use fsUpdate-at.
- Complete IsEmptyDir with noChildren (no strict descendant exists),
using a prefix relation in the descendant direction, as in Coq and
the fixed Lean model.
- Add PreconditionWitnesses (one inhabitant per precondition) and
All.agda (the import cone CI checks).
- Add .github/workflows/agda.yml: Agda 2.7.0.1 release archive,
digest-checked, and agda-stdlib v2.2 at a pinned commit (a recorded
§6 deviation), a no-postulate/no-pragma guard, an All.agda coverage
guard, then the canonical check.
All 10 modules check (exit 0). The 190 warnings are all
UnsupportedIndexedMatch from matching stdlib Dec, which only matters
under Cubical Agda; recorded in VERIFICATION.adoc.

…cular
Owner ruling 2026-11-09.
Isabelle and Mizar move to archive/proofs/ (kept, never deleted). Neither
had a CI lane or a checked run; under PROOF-POLICY Isabelle is
supplementary only and Mizar is a §4 exception. archive/proofs/README.adoc
maps all 139 archived theorems to successors by name: 103 name an Agda
successor, 29 only a Lean or Rocq one, 2 are only related, and 6 are
Mizar set-theory helpers that need none. Every consumer is updated in the
same change: both Justfiles, scripts/verify-proofs.sh and
scripts/validate-with-echidna.sh. build-agda now runs the canonical
invocation on All.agda.
Z3: filesystem_operations.smt2 asserted each theorem as an axiom before
checking it, and symlink_operations.smt2 never negated a goal. Both now
define the operations as array stores, check non-vacuity (sat) and
negate every goal (unsat). Dropping a precondition yields sat, so the
encoding separates true from false statements. The other three files
keep their axiomatic encoding with a §4 note saying so. verify-z3.sh
carries the new exact result sequences; all five pass.

governance.yml and secret-scanner.yml fail the moment they start, with no job run, on every push to this branch.
They fail the same way on main at 2d798b8 (push) and on Dependabot's e811e55.
That points to a workflow startup problem in the shared workflows they call, not to anything in this diff.
I don't have a fix to port into this PR yet, so I'm leaving them for whoever owns those workflows.
SonarCloud's quality gate (Security Rating C) was from this PR: unpinned curl redirects and an unprefixed glob in the new agda.yml. Both are fixed in 38b947f.
Owner ruling OD-32 asked for an experiment on the PROOF-POLICY
"transport first" route. Result: it does not work today.
- Agda2Dedukti is built on a 2021 Agda fork with no
--cubical-compatible, so it cannot read modules written to the
canonical invocation, and it predates agda-stdlib 2.x.
- Lambdapi's Rocq export drops rewrite rules. A minimal encoding whose
proof needs a definition to compute is accepted by lambdapi and by
dk check, and rejected by coqc after export.
- Lambdapi 4.0.0 has no Lean export.
Dedukti works as an independent kernel. The experiment records three
options for mathesis and echidna (rules as equations, rules as
definitions, a modern Agda front end), all untried. The audit gains a
section 7 summarising the follow-up work on this PR.

Review comments at @.github/workflows/agda.yml:
- Around line 74-82: Update the Agda source scan in the “No postulates or escape
pragmas” step to include `.agda` files in nested directories, or explicitly
reject nested Agda modules. Preserve the existing checks for postulates and
escape pragmas across all files that CI allows.
- Line 94: Update the import coverage check in the Agda workflow to recognise
both `import` and `open import` declarations, and ignore trailing whitespace
while still matching the requested module accurately.
- Around line 66-72: Update the escape-hatch scan in the Assert Agda version
step to distinguish Agda comments from declarations and pragmas, ignoring
occurrences of TERMINATING or postulate that appear only in line or block
comments while continuing to detect actual escape hatches.
Review comments at @archive/proofs/README.adoc:
- Line 173: Update the theorem count summary to report 102 Agda successors
instead of 103, preserving the other category counts and the total of 139.
- Around line 18-19: Update the proof display in the archive documentation to
use the current mkdir/rmdir Isabelle reference instead of the obsolete path, and
label archived proofs as unchecked rather than verified. Keep the existing
references to scripts/verify-proofs.sh and scripts/validate-with-echidna.sh
consistent with that status.
Review comments at @CLAUDE.md:
- Line 195: Update the Formal Verification heading in CLAUDE.md to distinguish
the four current systems from the two archived systems, so the count cannot be
read as six current systems.
Review comments at @docs/audits/2026-11-09-proof-ground-truth.adoc:
- Around line 176-177: Update the filesystem well-formedness claim in the audit
to distinguish Coq’s existing-parent invariant from the missing requirement that
parents be directories. Refer to Coq’s `well_formed` and
`mkdir_preserves_well_formed` results, noting that `mkdir` preserves the
invariant under its precondition; keep the claim that no model requires parents
to be directories.
Review comments at @docs/experiments/2026-11-09-dedukti-transport/README.adoc:
- Line 72: Update the `lambdapi export` command in the reproduction note to
suppress progress output before redirecting output to `Nat.dk`, so the file
contains only exported content. Preserve the subsequent `dk check Nat.dk`
validation.
Review comments at @docs/plans/VSH-ROUTE-PLAN-2026-11-04.adoc:
- Line 95: Update the Rust proof references returned by VerificationSuite to use
the files’ new archive/proofs/ location, and revise the claim that all consumers
were updated to reflect the actual changes. Preserve the existing Isabelle and
Mizar references apart from correcting their paths.
Review comments at @EXPLAINME.adoc:
- Around line 123-127: Update the generator for VERIFICATION_REPORT.md so
Isabelle and Mizar are identified as archived and unchecked, not as
cross-validation, and their affected properties are not marked complete.
Preserve the existing Z3 reporting and use the archive status recorded for the
Isabelle and Mizar proof trees.
- Line 124: Update the status vocabulary above the ledger to classify the Z3
row’s ASSUMED status, and reconcile the other ledger statuses with the stated
policy. Preserve the SMT trust boundary by keeping the row explicitly marked as
assumed without a proof certificate, or by using an equivalent classification
that retains that distinction.
Review comments at @Justfile:
- Line 320: Update the Markdown certificate coverage summary associated with
just certify to list the four proof systems shown in proof_systems. Verify the
theorem total against both certificates and retain the existing total only if it
matches.
- Around line 65-66: Update the proof-command guidance in README.adoc and
FAQ.adoc to remove the obsolete Isabelle and Mizar recipes, and direct readers
to the archived proof status and successor map referenced by the Justfile
comment.
Review comments at @PROOF-NEEDS.adoc:
- Around line 26-29: Update the Z3 row in the proof-status table to distinguish
the findings on main from the current PR state: note that two rewritten files
define operations and negate goals, and that all five files have exception
notes. Keep the row’s status as ASSUMED; do not present the main-commit findings
as current PR findings.
Review comments at @proofs/agda/PreconditionWitnesses.agda:
- Around line 34-41: Extend the precondition witnesses around
`rmdir-pre-inhabited` with a concrete reversible witness for the `mkdir`
operation and a corresponding witness for the non-empty `mkdir` sequence. Ensure
the reversible witness uses the existing mkdir and rmdir precondition witnesses
and permission evidence, so the sequence requires an inhabited `ReversibleDP`
rather than checking only individual preconditions.
Review comments at @proofs/agda/README.adoc:
- Line 37: Document the standard-library registration step before the `agda
--safe --without-K --cubical-compatible All.agda` command: explain how to add
the path to `standard-library.agda-lib` to Agda’s active libraries file, then
run the command.
Review comments at @proofs/README.adoc:
- Around line 3-4: Update the Agda compilation command in the README to check
All.agda with the same --safe, --without-K, and --cubical-compatible flags used
by CI, rather than checking only FilesystemModel.agda.
Review comments at @proofs/z3/filesystem_operations.smt2:
- Around line 7-8: Update the exception note in the filesystem operations proof
to clarify that, although the array identities are quantifier-free, the
submitted queries include quantifiers from the global child-of assertion and an
additional quantifier from rmdir-pre; do not imply that the quantifier-free
decision guarantee establishes termination for those queries.
- Around line 76-77: Add a negative check in the filesystem-operations proof
asserting that an existing strict descendant satisfies child-of for p and
exists-at in fs, then verify that rmdir-pre p fs is unsatisfiable. Update the
expected result sequence in the runner’s verify_file check to include this
additional unsat result.
Review comments at @proofs/z3/README.adoc:
- Line 7: Update the “See also” reference in this README and the corresponding
claim in the linked Lean README so both identify Agda as the authoritative
theory source, consistent with the introduction.
Review comments at @scripts/verify-proofs.sh:
- Line 151: In the Agda-unavailable branch for the All.agda check, update the
TOTAL_TESTS accounting to count the check once and remove the redundant
SKIPPED_TESTS increment, since log_skip already records the skip.

`hyperpolymath/standards` `3-practice/PROOF-POLICY.adoc` (owner ruling 2026-10-26) is
normative for this repository; this section is a short map for agents and changes in
the same change as that file. Which verifier carries which obligation:
* *Theory* → Agda as the source of truth, rechecked in Rocq and Lean. Owner
ruling 2026-11-09 adopts this order here: the Agda tree is the source and checks

[warning] 43-44: credential persistence through GitHub Actions artifacts (artipacked): does not set persist-credentials: false
Archive consumers that were missed:
- impl/rust-cli proof_refs, explain and help now point Isabelle entries
at archive/proofs/ and label them "archived, unchecked".
- ffi/rust no longer lists Isabelle or Mizar files as evidence.
- README.adoc and FAQ.adoc drop the removed build-isabelle/build-mizar
recipes; the report generator gets a historical-template banner.
- `just certify` no longer claims "256 theorems across 6 systems",
"100% precondition checking" or Zig memory safety; it points to the
ledger and the audit instead.
Agda CI:
- Drop the grep for postulates and pragmas; `--safe` already rejects
them (checked: "Cannot use TERMINATING pragma with safe flag").
- The All.agda coverage check now finds nested modules and accepts
`open import` and trailing whitespace. Checked against six cases,
including a missing import, a nested module and a name-prefix match.
- PreconditionWitnesses: ReversibleDP (mkdirOp a) emptyFS is inhabited.
Docs:
- Archive successor count: 102 Agda (not 103), 29, 2, 6 = 139.
- Audit: Coq already has a partial well_formed invariant (parents exist,
not parents-are-directories).
- Ledger, PROOF-NEEDS Z3 row, CLAUDE.md system count, Agda stdlib
registration step, Lean and Z3 README source-of-truth references.
- Z3 note: the queries are quantified, so termination is not guaranteed
by a decision procedure; verify-z3.sh times out unknowns (run: 25 ms).
- Dedukti experiment: use `--verbose 0` (checked: clean output, warning
on stderr) and warn that dk check accepts an empty file.
- verify-proofs.sh counts one skipped Agda check, not three.
cargo test: 827 passed, 0 failed, 15 ignored (rust-cli); ffi/rust 24 passed.

Hypatia CSA001 (FilesystemModel.agda): a text match on the word "postulated" in a historical comment, now reworded. No postulate exists, and --safe in CI would reject one.
Hypatia SD022 (experiment README): the README names the fork's parser by module (Agda.Interaction.Options.Base) instead of a src/full/ path that exists only in the external fork.
agda.yml escape-hatch scan: the grep step is removed. --safe already rejects postulates and pragmas (checked: "Cannot use TERMINATING pragma with safe flag").
agda.yml coverage, nested modules: the check now walks find . -name '*.agda' and maps paths to dotted module names.
agda.yml coverage, import forms: the check accepts open import and trailing whitespace, and rejects a name-prefix match. Tested locally on six cases.
Archive references:
impl/rust-cli (proof_refs, explain, help) points Isabelle entries at archive/proofs/ and labels them "archived, unchecked".
ffi/rust no longer lists Isabelle/Mizar as evidence.
README.adoc/FAQ.adoc drop the removed recipes.
The report generator carries a historical-template notice.
just certify summary: the unsupported "256 theorems across 6 systems", "100% precondition checking" and Zig memory-safety lines are gone; it now points to the ledger and audit.
Archive successor count: corrected to 102 Agda + 29 Lean/Rocq-only + 2 related + 6 helpers = 139.
CLAUDE.md system count: now "4 active systems; Isabelle/HOL and Mizar archived".
Audit, well-formedness: records Coq's partial well_formed invariant (parents exist), which doesn't require parents to be directories.
Ledger vocabulary: the Z3 row uses argued and states the §5 ASSUMED mapping.
PROOF-NEEDS.adoc Z3 row: separates the state on main from the state in this PR.
proofs/README.adoc: the command now checks All.agda under the canonical flags.
Z3 exception note: says the queries are quantified, so termination isn't guaranteed. verify-z3 fails unknowns and timeouts; the measured run takes 25 ms.
Z3 and Lean READMEs: both name Agda as the theory source.
Dedukti experiment: uses --verbose 0, and warns that dk check accepts an empty file (checked).
Cancelled Compilation Tests / Test (… on …) jobs are not from this PR.
On head dfae63c, Test (stable on macos-latest) and Test (nightly on macos-latest) were cancelled at the 30-minute job timeout, during the step "Run ignored tests (stress)" (cargo test --test stress_tests -- --ignored). In the log, stress_deep_nesting_no_stack_overflow, stress_large_file_1gb and stress_large_file_undo_streaming fail, and then the run hangs until the cancel.
main shows the same thing. On ce16ce3 (run 41343075278), all six Test (…) matrix jobs were cancelled in that same step. This PR changes neither stress_tests.rs nor compilation_tests.yml.
The cause is that the step's continue-on-error: true cannot absorb a job-level timeout. The ordinary Run tests step passes before the cancel in every case.
Proposed fix, as a separate change and not in this PR: give the step its own limit, so it fails inside the job and continue-on-error applies.
- name: Run ignored tests (stress)timeout-minutes: 10run: cargo test --test stress_tests -- --ignored --test-threads=1continue-on-error: true
The three failing stress tests (1 GB file, deep nesting) are a separate finding and need their own look.
Most Linux jobs on this head are still queued (runner backlog). I'll act on them once they report.
Hypatia check (dfae63c): one error, a stale alert from main.
The only annotation is proofs/agda/FilesystemModel.agda:1, CSA001, "Code scanning (Hypatia): hypatia/code_safety/agda_postulate -- 4 day(s) old". This is Hypatia's code_scanning_alerts rule re-reporting an alert that is already open on the default branch. It is not a new finding in this diff.
On main, FilesystemModel.agda:178 is postulate (the funext axiom).
On this head, grep -i postulat proofs/agda/FilesystemModel.agda matches nothing. This PR removes the axiom; the tree is checked under --safe, which would reject one.
No code change in this PR can clear it. It closes once main is rescanned after merge, or it can be dismissed on the Code scanning page as "fixed in #223" (owner action). I can't re-run or dismiss it from here.
The Zig verifier (prover_integration.zig), the Zig and Elixir proof
reference tables (main.zig, state.ex) still named proofs/isabelle/ and
proofs/mizar/, which the archive move removed; the Zig verifier would
fail with a missing file. They now point into archive/proofs/ and carry
a note that those trees are archived unchecked.
proof_refs.rs named RMOOperations.thy; the archived theory is
RMO_Operations.thy. The variable-assignment entry pointed at an
Isabelle file that never existed; it now says so.
Raised by the Codex review on #223.

Inline comments:
Review comments at @.github/workflows/agda.yml:
- Around line 88-89: Update the import coverage check in the workflow so
commented text in All.agda cannot satisfy the check for module m. Use Agda-aware
parsing or verify each expected module directly through the existing estate
invocation, preserving the current failure behaviour for genuinely missing
imports.
Review comments at @FAQ.adoc:
- Around line 70-71: Update the FAQ’s opening, proof-systems section, and
inventory notes, plus the equivalent claims in README.adoc, to distinguish
currently checked proof systems from archived Isabelle and Mizar proofs.
Describe Isabelle and Mizar as archived and unchecked, and avoid presenting them
as current cross-validation evidence.
Review comments at @ffi/rust/src/verification.rs:
- Line 125: Update the coverage table associated with the proof locations in
verification.rs so Isabelle and Mizar are marked as archived and unchecked, not
covered. Preserve the existing coverage status of all other systems.
Review comments at @impl/rust-cli/src/commands.rs:
- Around line 2332-2335: Update the inverse-proof claim in the `explain` output
so it does not state that all six systems checked the proof when Isabelle is
shown as archived and unchecked; qualify the claim to reflect only the systems
that actually verified it.
Review comments at @impl/rust-cli/src/proof_refs.rs:
- Line 239: Correct the RMO entries in the proof references, including the
`isabelle_location` shown, to point to the archived `RMO_Operations.thy` file
and accurate theorem locations where those proofs are present. Mark proofs
unavailable where no matching proof exists; do not retain unsupported line
references.
Review comments at @Justfile:
- Around line 377-380: Update the JSON certificate in the Coverage section to
remove the unsupported total_theorems count, or replace it with a supported,
clearly qualified count consistent with the stated coverage limitations.
Review comments at @proofs/lean4/README.adoc:
- Around line 9-10: Update the See also references in the Lean 4 README to point
to the archived Isabelle and Mizar proof trees, and describe them as archived
rather than as cross-validation resources.
- Around line 9-10: Update the proof-debt section in the README to report the
current status: one real gap and one Agda structural item, without counting
Isabelle or Mizar as active. Link to the latest audit and proof ledger, using
their existing locations or references rather than inventing new ones.
- Line 6: Update the documented local Lean proof-check command to use the named
library targets run by the Lean CI job, ensuring it checks
PreconditionWitnesses; also state which libraries remain excluded. Use the CI
target names and exclusion details rather than guessing them.
- Around line 5-6: Update the Coq README’s introduction and “See also” section
to identify Agda as the theory source of truth and Lean as a recheck leg,
keeping both references consistent with the distinction shown by the Agda and
Lean descriptions in the diff.
Review comments at @proofs/z3/filesystem_operations.smt2:
- Around line 10-11: Connect the `parent` and `child-of` relations so that when
`parent c = p`, `c` is recognised as a child of `p`; add a negative check using
`parent` to ensure `rmdir-pre` rejects `p` when `c` exists. Preserve the
existing termination-related constraints and supplementary-check scope.
- Around line 8-12: Update the ProofRef ranges for mkdir_rmdir and create_delete
so each range includes its corresponding reversibility check rather than
pointing to declarations.
- Line 32: Add satisfiability checks for both create-file and delete-file
preconditions alongside the existing mkdir and rmdir non-vacuity checks in the
filesystem operations proof. Update the expected result sequence in verify_file
within the verification script to include the two additional sat results,
preserving the existing theorem checks.
Review comments at @scripts/verify-proofs.sh:
- Line 148: Update verify-proofs.sh to run the same Agda module-coverage check
used in CI, and make verification fail when a module is missing from the import
graph. Keep the existing Agda validation command and its safeguards intact.

Load the registered Agda standard library
On a fresh GitHub runner, this only registers the standard library but does not select it, while the later bare agda ... All.agda invocation imports modules such as Data.String and Data.List; the new proof lane will therefore fail before type-checking the repository. Agda 2.7.0.1's official documentation says to use agda -l standard-library ..., or that a bare invocation works only after adding standard-library to the defaults file (Agda command-line examples), so create that file or pass the library explicitly.
The reason will be displayed to describe this comment to others. Learn more.
This one doesn't reproduce, so there's no change. Agda checks All.agda inside a project library: proofs/agda/valence-shell.agda-lib declares depend: standard-library. Agda resolves that dependency through ~/.agda/libraries, which this step writes. Library dependencies declared in a project .agda-lib are loaded without -l or a defaults file. defaults only applies to files outside any library.
The same setup works locally: stdlib registered in ~/.agda/libraries, no defaults file, bash scripts/check-agda.sh (the CI step since 20b9234), exit 0. The CI run on this head will confirm it on a fresh runner.
…gram
The ffi coverage table marked Lean as checking write, copy, move and
obliterate, but FileContentOperations, CopyMoveOperations and
RMOOperations do not build on the pinned toolchain; those rows now say
so. The Z3 column distinguishes the definitional encoding (✓), the
axiomatic copy/move/RMO files (A, ASSUMED) and the absent write
encoding (—), with a legend. The SECURITY.adoc trust diagram no longer
lists Isabelle/Mizar in the high-trust proof layer.

Reconcile the architecture diagram with the ledger
When readers use this current topology as a proof-status overview, the corrected dashboard here conflicts with the architecture diagram at lines 24–32, which still labels the proof layer “6 SYS,” calls Lean the primary system, includes Isabelle and Mizar, and advertises approximately 250 theorems. Update that diagram to reflect Agda as the source, the checked recheck legs, and the archived systems so the same document does not continue presenting the assurances this change withdraws.

132-140: Count skipped tools consistently.
When Lean or Agda is missing, the script calls log_skip, which increments SKIPPED_TESTS. It then increments only TOTAL_TESTS. This keeps the counters consistent. At line 185, SKIPPED_TESTS -eq TOTAL_TESTS still detects the case where no tool is installed. Lines 168-169 (unchanged) show the same pattern. This looks correct. The earlier double-count is fixed.

Summary
This PR re-runs every prover leg on
main(2d798b8) against the estate proof policy (hyperpolymath/standards3-practice/PROOF-POLICY.adoc). It then carries out the owner rulings of 2026-11-09, recorded as OD-30 to OD-34 in the route plan. The full record is indocs/audits/2026-11-09-proof-ground-truth.adoc.Soundness fix: Lean
RmdirPreconditionwas uninhabitedisEmptyDirchecked a path's ancestors instead of its descendants. Because the parent always exists, the precondition could never hold. As a result, every Lean theorem that assumed it was vacuous, including the composition theorems for any sequence containing mkdir or rmdir. The fix is one line.The new
PreconditionWitnesseslibrary proves that each precondition can be satisfied. It also proves that a non-empty directory is rejected. WeakeningisEmptyDirtoTruenow breaks the build; I checked this by mutation.
