fix(proofs): stop claiming SPARK proofs that do not exist; make the proof scaffold compile and fail closed - #74
A proof review on 2026-11-09 against standards/3-practice/PROOF-POLICY.adoc found three problems here. This PR corrects the claims and the tooling. It adds no new proofs.
The SPARK claims are unsupported.
Seven documents under runners/must/ call the SPARK conversion complete.
No Ada source sets SPARK_Mode, in any .ads, .adb or .gpr file, and there is no .adc configuration file. So gnatprove analyses none of the code.
The only contract aspects are four Pre and eight Post, on the bounded-string conversion functions in runners/must/src/must_types.ads. The first version of this PR wrongly said there were none; review caught it.
Outside SPARK those aspects are run-time assertions at most. SPARK-1 is now OPEN, and the documents are kept, each with a dated correction banner.
runners/must/src and mustfile/src are diverging implementations, not copies.
The copied proof scaffold did not compile.Types.idr, ApiTypes.lean and the ABI/ modules failed under their own provers.
The proof recipes failed open.
build/just/proofs.just reported SKIP with exit 0 when a prover was missing or a check failed.
The resynced gate also needed three more fixes, found in review:
lean exits 0 on sorry.
coqc exits 0 on Admitted.
A mistyped MANIFEST status was read as quarantine.
runners/must/SPARK-*.md (7 files): a "Status correction (2026-11-09)" banner. The body text is unchanged.
docs/status/PROOF-STATUS.adoc:
§5 status tokens; census "0 of 8 obligations PROVEN".
A section on what was checked, including the twelve aspects and the two diverging trees.
SPARK-1 scoped to the runners/must/src tree.
docs/status/PROOF-NEEDS.adoc: the prover guide mirrors PROOF-POLICY §1.
build/just/proofs.just, scripts/check-proofs.sh and scripts/scan-dangerous.sh now fail closed:
Every proof file must be listed in a MANIFEST as gated or quarantine, and any other status fails.
A gated module must compile and use no escape hatch (believe_me, sorry, Admitted, …) in code; comments are ignored.
A missing prover is an error.
verification/proofs/**: resynced from the template.
MANIFESTs for each prover.
Agda checked under the §2.1 invocation (--safe --without-K --cubical-compatible).
A pinned lean-toolchain.
A bounded TLA+ model (MC.tla/MC.cfg), with ProcessedMonotonic as a real action property, reported TESTED with its bounds.
The README maps Rust to Creusot/Pearlite and Verus, and gives the TLC command.
.gitignore: the template's Coq and Agda build-artifact entries.

believe_me in a gated Idris2 module;
a decrementing step against ProcessedMonotonic.
The toolchains were installed in the agent session, not through Guix or a container. That is a PROOF-POLICY §6 deviation. No CI lane runs these checks yet, so the checks are not continuous.
… proof scaffold so it compiles and cannot report a false green
SPARK: no .ads/.adb in runners/must/src or mustfile/src contains SPARK_Mode
or any contract aspect (Pre, Post, Global, Depends, Contract_Cases,
Loop_Invariant), so gnatprove has nothing to analyse. The seven
runners/must/SPARK-*.md documents that call the conversion complete now
open with a status correction and are kept as history. PROOF-STATUS records
the obligation as SPARK-1, OPEN, with the evidence.
Proof scaffold, resynced from rsr-template-repo (as verified in
hyperpolymath/rsr-template-repo#310):
- build/just/proofs.just: the old recipes printed "SKIP: idris2 not
installed" and exited 0. They now delegate to scripts/check-proofs.sh,
where a missing toolchain fails.
- verification/proofs: the stale copies did not compile (Types.idr,
ApiTypes.lean); the resynced set does, with MANIFESTs (gated or
quarantined), Agda under the PROOF-POLICY §2.1 invocation, and a bounded
TLA+ model (TESTED).
- PROOF-STATUS / PROOF-NEEDS: §5 status tokens and a census, no percentage;
the prover guide mirrors PROOF-POLICY.
Checked 2026-11-09: check-proofs.sh passes for idris2 0.7.0, Agda 2.6.3
(stdlib 1.7.3), Coq 8.18.0 and Lean 4.15.0.

Proof checks now use recorded manifests, validate expected pass and quarantine outcomes, and fail when a required prover is unavailable or proof files do not match the manifest.
Dangerous-construct scans now ignore comments.
Added bounded TLA+ model checks; results are classified as tested rather than proven.
Documentation
Proof status now reports eight open obligations and distinguishes proof, test and assumption statuses.
Guidance clarifies proof classifications, tool choices and which examples are not evidence of completed proofs.
SPARK status now marks the obligation open and identifies prior completion claims as unsupported.
The pull request updates proof guidance and status records, adds manifest-based checks for four provers and dangerous constructs, adjusts Idris2 and Lean proof sources, and configures a bounded TLA+ model check.
Changes: Proof verification and status
Layer / File(s)
Summary
Proof policy and obligation status docs/status/PROOF-NEEDS.adoc, verification/proofs/README.adoc, docs/status/PROOF-STATUS.adoc, runners/must/SPARK-*.md
The guidance maps obligation types to provers and describes proof grades, rechecks, and assumptions. The status summary reports eight open obligations and adds SPARK-1. The SPARK documents state that gnatprove analyses none of the repository’s Ada source and mark the obligation open.
The prover recipes call the shared checker. The checker validates tools and manifest entries, checks gated and quarantined modules, and detects missing or unlisted files. The dangerous-proof scan delegates to a script that ignores supported comments. Manifests record module statuses and check notes.
Idris2 comments prohibit proof escape hatches, and Bounded.inBounds no longer has quantity zero. Lean bounded-value declarations are outside ApiResult and bind max explicitly.
Bounded TLA+ model check verification/proofs/tlaplus/MC.tla, verification/proofs/tlaplus/MC.cfg, verification/proofs/tlaplus/StateMachine.tla
The new model defines a processing bound. The TLC configuration selects the specification, bound, invariants, and properties. The documentation identifies results under those bounds as tested, not proven.

Review comments at @build/just/proofs.just:
- Line 41: Add the missing scripts/scan-dangerous.sh used by
proof-scan-dangerous so just proof-check-all can complete after the prover
checks pass. Implement the expected dangerous-construct scan using the project’s
established rules, and ensure it ignores comments according to each of the four
prover languages’ syntax; identify those languages and rules from the repository
rather than assuming them.
Review comments at @docs/status/PROOF-STATUS.adoc:
- Around line 111-112: Update the claim in the PROOF-STATUS documentation and
the identical wording in all seven SPARK correction banners to acknowledge that
Pre and Post contract aspects exist, while making clear that their presence does
not establish the SPARK obligation is proven.
- Line 117: Update the runner description in PROOF-STATUS.adoc to reflect that
runners/must/src and mustfile/src are distinct implementations: must_types.ads
uses bounded strings in the former and indefinite containers and unbounded
strings in the latter. Track verification status separately for each tree so
proof of one is not attributed to the other.
Review comments at @scripts/check-proofs.sh:
- Line 72: Update the lean4 ERROR_RE in the command configuration so it also
detects Lean’s “declaration uses 'sorry'” warning. Document that
proof-scan-dangerous must run in the same CI lane as the Coq check, since
Admitted may produce no output for the script’s regex to detect.
- Around line 133-134: Validate each manifest entry’s status before running its
check, accepting only the exact values gated and quarantine. For any other
value, report the invalid status, increment the failure count, and skip the
check so it cannot be treated as quarantined.
Review comments at @verification/proofs/README.adoc:
- Line 16: Update the Rust verifier mapping headed by Creusot to include
Pearlite and Verus alongside Creusot, so the mapping reflects the full default
Rust toolset.
- Line 101: Update the verification instructions to state that the tlaplus/
directory is not checked by scripts/check-proofs.sh or just proof-check-all, and
provide the TLC invocation for its model using MC.cfg; use the project’s actual
model and configuration details rather than guessing the command.
Review comments at @verification/proofs/tlaplus/MC.cfg:
- Line 10: Update the `EventualCompletion` check in `MC.cfg` so it is not
presented as proving that every request completes or fails. Either strengthen
the model to establish per-request progress, including removal of each request
from `queue`, or label the existing property as checking only that the system
eventually reaches a terminal state once.
- Line 7: Update ProcessedMonotonic in StateMachine.tla to express the temporal
guarantee that processed never decreases between states, then select it with
PROPERTY rather than INVARIANT in MC.cfg. Preserve any existing non-negativity
check separately if it remains needed.

The namespace change is real, but the inspected repository shows no affected consumer or compatibility requirement. A downstream proof that uses the former qualified names is hypothetical.
…otonicity for real
Found by review on hyperpolymath/contractiles#74, which carries a copy of
this scaffold; each was reproduced here before fixing.
- A gated module that compiles but uses an escape hatch passed:
`lean` exits 0 on `sorry` (a warning), `coqc` exits 0 silently on
`Admitted`, and `idris2 --check` accepts `believe_me`. scan-dangerous.sh
covered only verification/proofs/, so not the coaptation core.
check_one now runs scan-dangerous.sh (which takes file arguments) on
every module, and the Lean pattern also matches the `sorry` warning.
- Any MANIFEST status other than `gated` was read as quarantine, so a
typo such as `Gated` let a failing module pass. Unknown statuses now
fail.
- ProcessedMonotonic only checked `processed >= 0`, which a step from
4 to 3 satisfies. It is now the action property
[][processed' >= processed]_processed; the old invariant is kept as
ProcessedNonNegative. EventualCompletion's comment no longer claims
per-request completion (this model never dequeues).
- README: Rust maps to Creusot/Pearlite and Verus (PROOF-POLICY §1.2);
tlaplus/ is not run by check-proofs.sh, with the TLC command given.
Checked: all four prover gates pass; negative controls for Lean `sorry`,
Coq `Admitted`, a `Gated` typo on a failing module, and `believe_me` in
Coaptation.idr each fail the gate. TLC 1.8.0 passes MC.cfg (164
distinct states) and reports ProcessedMonotonic violated when a
decrementing step is injected.

…); close the gate's fail-open paths
Review (CodeRabbit) on this PR, each finding checked against the code:
- The correction banners and PROOF-STATUS said no contract aspect
exists. That was wrong: runners/must/src/must_types.ads has four Pre
and eight Post aspects on its eight bounded-string conversion
functions. Nothing sets SPARK_Mode (no .ads/.adb/.gpr, no .adc), so
gnatprove analyses none of it and SPARK-1 stays OPEN; the wording now
says exactly that.
- runners/must/src and mustfile/src are diverging implementations, not
copies (bounded strings vs indefinite containers and unbounded strings;
must.adb and must_types.* differ). PROOF-STATUS and the SPARK-1 row now
say so and require SPARK work to name its tree.
- proof-scan-dangerous called scripts/scan-dangerous.sh, which the resync
left out; added from the template.
- Ported from hyperpolymath/rsr-template-repo#310 (d887c48): every gated
module must also pass scan-dangerous.sh (lean exits 0 on `sorry`, coqc
on `Admitted`); an unknown MANIFEST status fails instead of reading as
quarantine; ProcessedMonotonic is now an action property
([][processed' >= processed]_processed) with ProcessedNonNegative kept
as the invariant; EventualCompletion no longer claims per-request
completion; README maps Rust to Creusot/Pearlite and Verus and gives
the TLC command, since check-proofs.sh does not run tlaplus/.
- .gitignore: the template's Coq and Agda build-artifact entries.
Checked: all four prover gates and scan-dangerous.sh pass; TLC 1.8.0
passes MC.cfg. The negative controls were run on the template copy of
the same scripts.

Dogfood Gate / Validate K9 contracts is red on this PR, but the failure comes from main. The same job fails on main at 2246caa (run 42499662729), and this PR touches no .k9 or .k9.ncl file.
.github/hooks/validate-k9.sh reports 6 errors in 3 files:
The fix belongs to the K9 contracts, not to this proof-honesty PR. It needs content decisions, such as what each pedigree should say.
The validator may be applying the wrong rules to coordination.k9. That file has its own grammar (coordination-k9 v1.2), and the contract checks may not apply to it.
No fix exists yet. I'm raising it with the owner as a separate item.

Nested block comments are not tracked.
Idris2, Lean, Agda and Coq all allow nested block comments. The first closer ends the block here. Text after an inner closer is then scanned as code. This causes false positives only, so the gate stays fail-closed. Treat nesting as a known limitation.
31-31: Functional Correctness · Low value
PATTERNS matches substrings, not whole identifiers.
The pattern sorry also matches identifiers such as sorryNot. The pattern also misses Lean's admit. A substring match produces false positives. The missing admit is a false-negative path for Lean, but Lean emits the same declaration uses 'sorry' warning, which check-proofs.sh catches. Add word boundaries to reduce false positives.

Major · Security & Privacy · Heavy lift
Comment stripping can fail open on string literals containing comment markers.
The stripper does not recognise quoted strings. A string such as "--" in Idris2, Lean or Agda truncates the line. Code after it on the same line is hidden from the scan. A believe_me placed after such a string passes the gate. A {- inside a string opens a block comment and hides the following lines.
The script header documents this limitation. The gate is used as a fail-closed check, so the limitation is a real false-negative path. Add string-literal handling to the awk state machine: track " and skip \" escapes. For Coq, also handle "" inside strings.

Review comment at @scripts/scan-dangerous.sh around lines 38 - 63:
Update the awk state machine in strip_comments to track quoted strings and
ignore comment markers until the string closes; skip escaped quotes and handle
Coq’s doubled-quote string escapes. Preserve the existing line- and
block-comment handling outside strings so comment-like text in strings cannot
hide code from the scan.

Unreadable or missing files can fail open.
The strip_comments function returns awk's status. The pipeline at line 67 ends with grep ... || true, and pipefail is masked by || true. A missing file passes the scan silently because awk's error goes to stderr and no match is found. In check-proofs.sh the compile step runs first, so the case is unlikely there. The no-argument mode uses find, so it is safe. Add an explicit [[ -f "$f" ]] check that counts a missing file as a failure.

Review comment at @scripts/scan-dangerous.sh around lines 65 - 76:
Update the file-processing loop that calls strip_comments to check that each
non-empty path refers to an existing file before scanning it. For a missing
file, report a failure, increment dangerous, and skip the grep pipeline so the
scan cannot pass silently.

Specify the location of the TLC JAR.
The checkout does not contain tla2tools.jar in verification/proofs/tlaplus, and these instructions do not place it there. If the JAR is installed elsewhere, this command fails to find tlc2.TLC. Use the installed JAR’s full path or give instructions to place it in this directory. (github.com)

Update the TLC command in the verification instructions to locate
`tla2tools.jar` reliably: use the installed JAR’s full path or clearly instruct
readers to place it in the expected directory before running the command.
Preserve the existing TLC options and model configuration.

Document the JAR location.
If TLC is installed outside the model directory, this command cannot find tlc2.TLC. The README gives the same command but does not say to copy the JAR there. Document that requirement or use the installed JAR’s path in both commands. (raw.githubusercontent.com)

Review comment at @verification/proofs/tlaplus/MC.cfg at line 2:
Update the TLC invocation in the model instructions and the matching README
command to make the JAR location explicit: either document that tl a2tools.jar
must be in the working directory or use the installed JAR’s path in both
commands. Keep the two documented invocations consistent.
