proofs(agda): the wager experiment, stages 2 to 4 (roles, the source calculus, the translation) - #88
Stages 2, 3 and 4 of the wager experiment in Cubical Agda. Stages 0 and 1 are in main since pull request 87.
Stage 2: roles as a grade instance (theorems T1, T2 and T4).
Stage 3: the source calculus, a small fragment of System FC with roles, and the classic unsound program.
Stage 4: the translation of the source calculus into the target calculus, and the simulation (theorems T3 and T5).
Status: stages 0 to 4 of 7 are complete. The claim W is not decided yet. T6 and T7 are not attempted. verification/proofs/agda/Wager/VERDICT.adoc is a draft.
The experiment claims no ET obligation. It does not change docs/theory/OBLIGATIONS.adoc, AFFIRMATION.adoc or any .a2ml file.
Changes
Stage 2
Wager/Role/Role.agda (T1): the two composition tables for roles, decided law by law.
Lawful table (nominal · phantom = phantom): all 15 law fields hold.
GHC table (nominal · phantom = nominal): 14 law fields hold, and a · 0 = 0 fails at nominal only.
Wager/Role/Noninterference.agda, Lawful.agda (T2): role soundness as noninterference, for a signature that respects its declared grades.
Wager/Role/ClassicProofs.agda (T4): the classic type-level function is rejected at the grade representational.
The Proxy test, and Wager/Role/Role4.agda (a 4-point structure, laws only).
Stage 3
Wager/FC/: the source calculus, after Breitner, Eisenberg, Peyton Jones and Weirich. It has newtypes with declared roles, total closed type-level functions, coercions at the three roles (the relation Co), cast and coerce.
Wager/Erased/Untyped.agda: the untyped calculus after erasure, with big-step evaluation.
With the role check, a representational coercion keeps the erased type, and erasure preserves typing.
The classic unsound program: the role check rejects it, and it is unsound if the check is ignored.
Stage 4
Wager/Trans/Scheme.agda, Target.agda: a newtype becomes a trope state on its representation. A state scheme gives the number of states. The row scheme exists for each signature.
Wager/Trans/Coercion.agda: a representational coercion becomes a term built from trope transitions (wrap, unwrap) and the maps of functions, pairs and sums. A nominal coercion becomes conversion. The target has no cast.
Wager/Trans/Typing.agda: a translated coercion is a typed term in each grade algebra. A translated program is typed in each grade algebra in which the grade 1 is unrestricted.
Wager/Trans/Simulation.agda (T3, T5): the erasure of a translated coercion is observationally the identity function. The erased source program and the erased translation evaluate to observationally equal values.
Wager/Trans/RoleCorrespondence.agda: the inferred source role of a newtype parameter is the least grade that target kinding accepts. The target signature respects its declared grades, so the hypothesis of T2 holds for it.
Wager/Trans/TwoStateProofs.agda: a checked counterexample. A signature with a phantom newtype and a type-level function that looks at its argument has no translation with two-state tropes.
Wager/Erased/LogRel.agda: observational equality of untyped values (a logical relation, used in statements only).
Wager/Grade/Trivial.agda: the one-point grade algebra. Wager/L1/KindingInversion.agda: 3 more inversion lemmas.
All stages
Wager/Statements.agda: the statements of each stage were committed before their proofs. No frozen statement changed. Wager/Proofs.agda: one inhabitant for each statement.
Wager/Examples/Stage2.agda, Stage3.agda, Stage4.agda: accepted and rejected closed examples.
VERDICT.adoc (draft), both ledgers, DESIGN-CHOICES.adoc (DC-2.x, DC-3.x, DC-4.x), TOOLCHAIN.adoc (gate watch of each stage).
docs/status/PROOF-STATUS.adoc: the marker gate:agda gated=64 and the rows for stages 2 to 4. CHANGELOG.adoc: the entry now says stages 0 to 4.
Results that the owner can check in VERDICT.adoc:
T1 is PROVED. T4 is PROVED.
T2 is PROVED WITH CHANGE (class: signature primitive). It needs the hypothesis that each constant and each primitive respects its declared grade. Each signature that the translation gives meets this hypothesis.
T3 is PROVED.
T5 is PROVED WITH CHANGE (class: signature primitive). A newtype with a parameter needs more than one wrapped trope state. With two-state tropes T5 is false, and a checked counterexample exists. Typing of a whole program needs a grade algebra with an unrestricted grade 1.
The relation ledger has no ADDED entry. The rule-diff ledger is empty. The target calculus did not change in stages 2, 3 and 4.
Limits (DC-3.1, DC-3.2, DC-4.1, DC-4.6): a type is closed, a term has no type variable, the body of a newtype cannot mention a declared newtype, and the result of a type-level function is a base type. "Observationally equal" is a logical relation, and contextual equivalence is not defined.
Note on the branch history
Pull request 87 was squash-merged while Stage 2 was in work. The two Stage 2 commits are rebased onto main. One merge commit keeps the old branch head as a second parent, so that the push needed no force. The diff against main has the changes of stages 2 to 4 only.
RSR Quality Checklist
Required
Tests pass (just test or equivalent). Run in the session: scripts/check-proofs.sh agda (PASS, 64 modules), scripts/scan-dangerous.sh (PASS), scripts/check-proof-status.sh (PASS), scripts/check-root-shape.sh (PASS), scripts/check-no-md-in-docs.sh (PASS). Not run in the session: the Lean4 gate (no Lean toolchain there). CI runs it.
Code is formatted. Not applicable: the repository has no formatter for Agda.
Linter is clean. A clean build prints no warning. One warning class is silenced in 35 of the 64 files (UnsupportedIndexedMatch, DC-0.3).

CHANGELOG or release notes updated
New dependencies reviewed for license compatibility. Not applicable: no new dependency.
ABI/FFI changes validated. Not applicable.
Testing
The gate was watched to fail at the end of each stage. TOOLCHAIN.adoc has the records.
Stage 2: the lawful table with the GHC entry, a false lemma, and a postulate each fail the gate.
Stage 3: a false lemma (the wrong declaration passes the role check), a postulate, and a changed equation of the type-level function each fail the gate.
Stage 4: a false lemma (no function looks at the argument of a newtype), a postulate, and a changed translation (the map of a sum exchanges the two injections) each fail the gate.
4 checks fail on main for reasons outside this work (lint-workflows, Validate K9 contracts, Hypatia neurosymbolic scan, SonarQube). Pull request 87 has the analysis.
Stage 0 of the systemet wager experiment for coercions and roles.
Local branch only. Nothing is pushed.
- Pin Agda 2.8.0 and agda/cubical v0.9 (TOOLCHAIN.adoc).
- Add the agda MANIFEST, the library file and a toolchain anchor module.
- Record the gate-failure tests: false lemma, postulate, hole.
- Record the Stage 0 design choices (DESIGN-CHOICES.adoc).
- Add the one-page plan (PLAN.adoc).
Known red gate: scripts/check-proof-status.sh needs a marker line in
docs/status/PROOF-STATUS.adoc. The task forbids an edit of that file.

T0 uses 14 of the 15 law fields. It does not use le-antisym.
Known red gate: scripts/check-proof-status.sh (marker line in
docs/status/PROOF-STATUS.adoc, which the task forbids to edit).

The owner asked for the push and for the updates that put the
repository in a consistent state.
- docs/status/PROOF-STATUS.adoc: marker line gate:agda gated=29, one
summary row and one section for the wager experiment. The section
says that the experiment claims no ET obligation.
- .github/workflows/proofs.yml: an agda job. It installs the pinned
Agda 2.8.0 tarball (checksum-verified) and the pinned cubical v0.9
commit, and runs scripts/check-proofs.sh agda.
- verification/proofs/README.adoc: the layout shows agda/.
- Justfile: the test recipe also runs the Agda gate.
- CHANGELOG.adoc: one entry.
- Wager notes: VERDICT, TOOLCHAIN, PLAN and DESIGN-CHOICES (DC-1.7)
record the change.
Not changed: docs/theory/OBLIGATIONS.adoc, AFFIRMATION.adoc and each
.a2ml file. A new obligation needs an ADR from the owner.

- Role/Noninterference: noninterference for a composition table and a
signature that respects its declared grades. The proof does not use
the law a * 0 = 0, so the GHC table is an instance.
- Role/Lawful: T2 with the lawful table (a grade below representational
respects the equivalence; the grade phantom gives equal normal
forms), and a sufficient condition for validity.
- Role/ClassicProofs: T4 (the classic function is rejected at the grade
representational, and its results are not equivalent), and the Proxy
test with a generative constant whose parameter is declared phantom.
- L1/KindingInversion: inversion of graded kinding.
- Proofs.agda: one inhabitant for each Stage 2 statement. The
statements are unchanged since the previous commit.
- Examples/Stage2: accepted and rejected closed examples, the GHC
table instance, and the newtype Age as a two-state trope.
- VERDICT draft: T1 PROVED, T2 PROVED WITH CHANGE (signature
primitive), T4 PROVED, and the answer to "which table is sound".
- Ledgers: no ADDED relation; the rule-diff ledger stays empty.
- PROOF-STATUS: marker gate:agda gated=41 and the Stage 2 rows.

Updated the proof experiment status to reflect progress through Stage 4; Stages 5–7 remain unattempted.
Expanded the status, verdict and design notes with results, limitations and conditions for the completed stages.
Verification
Expanded formal proof coverage for role behaviour, source-calculus soundness, erasure and translation properties.
Added examples demonstrating accepted and rejected cases, evaluation behaviour and translation results.
Stages 2–4 extend the Agda wager experiment with role algebras and proofs, a source calculus with erasure, and source-to-target translation results. The proof gate now lists 64 gated modules. The records mark T1–T5 proved, with T2 and T5 proved with changes; T6 and T7 remain unattempted.
Changes: Wager proof stages 2–4

A review bot on pull request 87 named two documentation points.
Both are real.
- TOOLCHAIN.adoc: the install step now adds a line to the Agda
`libraries` file. Before, it replaced the file, which removes the
libraries that a developer has registered.
- TOOLCHAIN.adoc, PLAN.adoc: sentences about the guardedness decision,
the status drift gate and the stage status were stale. They now say
what is true after the decisions of the owner.

Errors in the K9 files ("Missing pedigree block"). This branch changes no K9 file.
None from this branch. The K9 files need their pedigree blocks.

Inline comments:
Review comments at @verification/proofs/agda/Wager/VERDICT.adoc:
- Line 112: Update the lawful-table soundness condition to require the signature
to satisfy Valid, including its primitives, as well as having no generative
constant with a phantom parameter; do not state that excluding phantom
parameters alone is sufficient.
- Line 117: Revise the description of the four-point structure to present it as
a candidate; the checked results establish its grade laws and GHC multiplication
rule, but do not claim that it restores phantom coercions or is minimal unless
those properties are proved.
- Line 153: Update the F8 claim in the `VERDICT` entry to state only that `Proxy
Int` and `Proxy Bool` are not equivalent under `≈`, as proved by
`Wager.Proofs.no-phantom-coercion`, when `Proxy` is representational. Remove the
unsupported claim that systemet cannot type phantom coercions; leave whether a
term or trope encoding can type the coercion to Stage 4.

GitHub Actions: Static Analysis Gate / Hypatia neurosymbolic scan: proofs(agda): the wager experiment, stage 2 (roles as a grade instance)
Add a small fragment of System FC with roles as the source calculus:
signature (newtypes, declared roles, total type-level functions), types,
coercions (the relation Co, in the source only), terms with cast and
coerce, and erasure into an untyped calculus with big-step evaluation.
Add the Stage 3 statements to Wager/Statements.agda as types. The
statements are frozen from this commit.
Co-Authored-By: Claude <noreply@anthropic.com>
Claude-Session: https://claude.ai/code/session_0136P7ZmiFSCoB3UR9Kk56rK
…ssic program
Prove the Stage 3 statements for the source calculus:
- a nominal coercion keeps the nominal value of a type;
- with the role check, a representational coercion keeps the erased type;
- erasure removes each cast, and coerce erases to the identity function;
- with the role check, erasure preserves typing;
- the role check rejects the classic unsound program, the program is
unsound if the check is ignored, and the correct declaration has no
coercion between T Age and T Int.
Add accepted and rejected closed examples. Record the design choices
DC-3.1 to DC-3.6, the ledger entries, the gate watch and the draft
verdict for Stage 3. The Agda gate now has 51 modules.

- The lawful table is sound for a signature that satisfies Valid. The
condition on constants alone is not proved to be sufficient.
- The 4-point role structure is a candidate. Stage 2 proved its laws only.
- Finding F8 is about the relation of representational equivalence only.
It does not show that no target term can do a phantom coercion.
- Finding F7 names the one signature that Agda checked.

Claude-Session: https://claude.ai/code/session_0136P7ZmiFSCoB3UR9Kk56rK
Add the translation of the source calculus into the target calculus:
state schemes for newtypes, the target signature, the translation of
types, of coercions (trope transitions and functorial maps) and of
terms, the erasure of the target, and a logical relation on untyped
values as observational equality.
Add the Stage 4 statements to Wager/Statements.agda as types (T3, T5,
role correspondence, and the two-state result). The statements are
frozen from this commit.
Move the example signature of Stage 3 to Wager/FC/Tagged.agda, so that
the statements can name it.
Co-Authored-By: Claude <noreply@anthropic.com>
Claude-Session: https://claude.ai/code/session_0136P7ZmiFSCoB3UR9Kk56rK
Prove the Stage 4 statements for the translation:
- a representational coercion is an ordinary typed term of the target,
in each grade algebra (trope transitions and functorial maps, no cast);
- T3: the erasure of each translated coercion is observationally equal
to the identity function;
- T5: the translation preserves typing (for a grade algebra with an
unrestricted grade 1), and the erased source program and the erased
translation evaluate to observationally equal values;
- role correspondence: the inferred source role is the least grade that
target kinding accepts for the body of a newtype;
- the target signature of the translation respects its declared grades;
- a checked counterexample: a signature with a phantom newtype and a
function that looks at its argument has no translation with two-state
tropes. The translation with one state for each row of function
results exists for each signature.
Add accepted and rejected closed examples, the one-point grade algebra,
and three inversion lemmas for graded kinding. Record the design choices
DC-4.1 to DC-4.8, the ledger entries, the gate watch and the draft
verdict for Stage 4. The Agda gate now has 64 modules.

Review comments at @verification/proofs/agda/Wager/VERDICT.adoc:
- Line 286: Revise the Stage 4 statement associated with finding F12 to limit
its result to phantom coercions between newtype instances under the row-scheme
encoding, supported by the checked evidence. State explicitly that this does not
resolve the Stage 2 `Proxy` signature question, since Stage 4 does not translate
`Proxy`.
- Around line 321-322: Update the F15 statement about finite states for each
newtype to make it conditional on the signature being finite, including finite
Fam and Base for the rowScheme index type Fam → Base, and explicitly state that
Agda did not check this claim. Preserve the surrounding scope of F15.

Update the summary, changes, results, and testing sections to cover Stage 4,
including translation, typing preservation, simulation, role correspondence, and
two-state translation results. Correct the stated completion status and related

Narrow the claim that Stage 4 decided the F8 question.
F8 covers Proxy. Proxy is a generative constant that takes the phantom argument as a type argument. Stage 4 does not translate Proxy. It translates source newtypes into states that carry an index (rowScheme), and F12 says F7 and F8 do not apply to that encoding.
The checked evidence is tag-typed for Tag Int → Tag Bool and coercion-is-a-term for representational coercions. This evidence shows that a phantom coercion between instances of a newtype is a typed target term under the row scheme. It does not show that the Proxy coercion of the Stage 2 signature has a typed term.
State the Stage 4 result for the newtype and row-scheme encoding only. Say that the Stage 2 Proxy signature remains open. This follows the repository rule "Report faithfully — no overclaim".

| With `Proxy` declared representational the signature is valid, and `Proxy Age ≈ Proxy Int` holds.
But `Proxy Int` and `Proxy Bool` are not related by `≈` (`Wager.Proofs.no-phantom-coercion`). GHC accepts a coercion between them.
This result is about the relation `≈` only. It does not show that no term of the target calculus can do this coercion.
- Stage 4 decided the question (finding F12): a phantom coercion between two instances of a newtype is a typed term of the target.+ Stage 4 shows a related result (finding F12): with the row scheme, a phantom coercion between two instances of a newtype is a typed term of the target.+ This does not decide the question for `Proxy` in the signature of Stage 2.

Revise the Stage 4 statement associated with finding F12 to limit its result to
phantom coercions between newtype instances under the row-scheme encoding,
supported by the checked evidence. State explicitly that this does not resolve
the Stage 2 `Proxy` signature question, since Stage 4 does not translate
`Proxy`.

State that the finite-state claim is not checked in Agda.
F15 says that a finite number of states for each newtype is enough. Line 168 says that Agda did not check the matching sentence about the row scheme. The two statements disagree in strength.
The claim also needs a finite signature. rowScheme has the index type Fam → Base. This type is finite only if Fam and Base are finite.
Add the same caveat to F15, and state the finiteness assumption.

Stage 2
Wager/Role/Role.agda(T1): the two composition tables for roles, decided law by law.nominal · phantom = phantom): all 15 law fields hold.nominal · phantom = nominal): 14 law fields hold, anda · 0 = 0fails atnominalonly.Wager/Role/Noninterference.agda,Lawful.agda(T2): role soundness as noninterference, for a signature that respects its declared grades.Wager/Role/ClassicProofs.agda(T4): the classic type-level function is rejected at the grade representational.Wager/Role/Role4.agda(a 4-point structure, laws only).Stage 3
Wager/FC/: the source calculus, after Breitner, Eisenberg, Peyton Jones and Weirich. It has newtypes with declared roles, total closed type-level functions, coercions at the three roles (the relationCo),castandcoerce.Wager/Erased/Untyped.agda: the untyped calculus after erasure, with big-step evaluation.Stage 4
Wager/Trans/Scheme.agda,Target.agda: a newtype becomes a trope state on its representation. A state scheme gives the number of states. The row scheme exists for each signature.Wager/Trans/Coercion.agda: a representational coercion becomes a term built from trope transitions (wrap, unwrap) and the maps of functions, pairs and sums. A nominal coercion becomes conversion. The target has no cast.Wager/Trans/Typing.agda: a translated coercion is a typed term in each grade algebra. A translated program is typed in each grade algebra in which the grade1is unrestricted.Wager/Trans/Simulation.agda(T3, T5): the erasure of a translated coercion is observationally the identity function. The erased source program and the erased translation evaluate to observationally equal values.Wager/Trans/RoleCorrespondence.agda: the inferred source role of a newtype parameter is the least grade that target kinding accepts. The target signature respects its declared grades, so the hypothesis of T2 holds for it.Wager/Trans/TwoStateProofs.agda: a checked counterexample. A signature with a phantom newtype and a type-level function that looks at its argument has no translation with two-state tropes.Wager/Erased/LogRel.agda: observational equality of untyped values (a logical relation, used in statements only).Wager/Grade/Trivial.agda: the one-point grade algebra.Wager/L1/KindingInversion.agda: 3 more inversion lemmas.All stages
Wager/Statements.agda: the statements of each stage were committed before their proofs. No frozen statement changed.Wager/Proofs.agda: one inhabitant for each statement.Wager/Examples/Stage2.agda,Stage3.agda,Stage4.agda: accepted and rejected closed examples.VERDICT.adoc(draft), both ledgers,DESIGN-CHOICES.adoc(DC-2.x, DC-3.x, DC-4.x),TOOLCHAIN.adoc(gate watch of each stage).docs/status/PROOF-STATUS.adoc: the markergate:agda gated=64and the rows for stages 2 to 4.CHANGELOG.adoc: the entry now says stages 0 to 4.Results that the owner can check in
VERDICT.adoc:1.Limits (DC-3.1, DC-3.2, DC-4.1, DC-4.6): a type is closed, a term has no type variable, the body of a newtype cannot mention a declared newtype, and the result of a type-level function is a base type. "Observationally equal" is a logical relation, and contextual equivalence is not defined.
