fix(formal): retire the three refuted Admitted statements to Prop (D0, D0b) - #422
This implements plan rung P0 with the owner-ratified D0 and D0b (2026-11-05; recorded in #421).
Three refuted statements were Admitted alongside Qed refutations, so the Coq build could derive False:
Semantics.preservation, refuted by Counterexample.v;
step_pop_disjoint_from_type_l1, refuted by Counterexample_StepPop.v;
preservation_l1, refuted by Counterexample_PreservationL1.v.
This PR retires all three to Prop statements. It does not close them: no refuted statement is proved.
formal/ changes
Semantics.v: Theorem preservation … Admitted. becomes Definition preservation_stmt : Prop. The roughly 700-line partial proof script and its closure-status notes are removed; they remain in git history.
Counterexample.v: new preservation_false : ~ preservation_stmt (Qed). The witnesses are unchanged.
Semantics_L1.v: step_pop_disjoint_from_type_l1 and preservation_l1 become …_stmt : Prop.
Counterexample_StepPop.v and Counterexample_PreservationL1.v: the _FALSE theorems are restated as ~ …_stmt, with the same proofs.
TypingL2.v: preservation_l2_via_l1 and preservation_l2_lift_case now take preservation_l1_stmt as an explicit hypothesis. Before, they silently depended on the false Admitted.
File banners are updated to say "retired, not closed".
CI
coq-build.yml replaces the Print Assumptions step (which named the retired preservation_l1) with a no-False gate:
it fails on any Admitted., Axiom or Parameter in a _CoqProject file;
it requires 6/6 results to print "Closed under the global context" (the three refutations and the three L2 results).
Docs
The owner asked me to draft these:
CLAUDE.md fence: a dated revision note at the top, plus edits to the TL;DR, DO NOT items 1, 3 and 5, and the anti-pattern list. The intent is unchanged: never prove a refuted statement.
PROOF-NEEDS.adoc: the count marker goes from 3 to 0, with a retirement note and updated boundary rows.
EXPLAINME.adoc and V1-TO-V2.adoc: updated to match.
Owner action outside this repo: the memory entry feedback_ephapax_no_patching_legacy_preservation.md should get the same revision: the legacy statement is retired to preservation_stmt, refuted by preservation_false, and must never become Admitted again.
Verification (local, coqc 8.18.0)
Full coq_makefile build: exit 0, about 1m40s.
0 Admitted and 0 Axiom across formal/. All 30 Print Assumptions in the build print "Closed under the global context".
The new gate's script, extracted from the workflow YAML, passes on this tree. With a dummy Admitted planted in Echo.v, it fails.
scripts/status-gate.sh --proofs reports OK (0).
The survey's SurveyCounterexamples.v F0 no longer compiles (Semantics.preservation not found), as expected.

…, D0b)
Owner-ratified 2026-11-05. While Semantics.preservation,
step_pop_disjoint_from_type_l1 and preservation_l1 were Admitted next to
Qed refutations, the build could derive False.
- Semantics.preservation -> preservation_stmt : Prop; Counterexample.v
adds preservation_false : ~ preservation_stmt (Qed). The 700-line
partial proof script is removed (kept in git history).
- step_pop_disjoint_from_type_l1 and preservation_l1 ->
..._stmt : Prop; their _FALSE refutations are restated against them.
- preservation_l2_via_l1 / preservation_l2_lift_case take
preservation_l1_stmt as an explicit hypothesis.
- coq-build.yml: the Print Assumptions step becomes a no-False gate
(no Admitted/Axiom/Parameter in _CoqProject files; 6/6 results closed).
- CLAUDE.md fence, PROOF-NEEDS (marker 3 -> 0), EXPLAINME and V1-TO-V2
record the retirement. Retired, not closed: no refuted statement is
proved.
Verified locally: coqc 8.18.0 full build exit 0; 0 Admitted, 0 Axiom;
30/30 Print Assumptions in the build closed; the gate fails on a
planted Admitted; status-gate --proofs OK (0).

Updated proof-status guides to reflect that the legacy and unrestricted L1 preservation claims are retired and refuted, rather than open proof obligations.
Clarified that L2 preservation results require an explicit L1 preservation hypothesis.
Verification
CI now checks for Admitted, Axiom, and Parameter declarations, and verifies that six audited results are closed under the global context.
Added a formal refutation of the legacy preservation claim.
Tests
Updated the documented all-target test count to 504.
The pull request retires three false preservation claims as proposition definitions, adds a counterexample theorem for legacy preservation, and makes L2 preservation results require an explicit L1 proposition. The Coq workflow adds checks for forbidden declarations and closed assumptions. Documentation updates these statuses and the reported test total.
Changes: Formal preservation boundary
Layer / File(s)
Summary
Retire and refute preservation claims formal/Semantics.v, formal/Semantics_L1.v, formal/Counterexample.v, formal/Counterexample_PreservationL1.v, formal/Counterexample_StepPop.v
The admitted legacy theorem and two unrestricted L1 results are replaced by Prop definitions. Counterexample proofs target the named propositions, and preservation_false proves the negation of the legacy statement.
Require the L1 proposition in L2 results formal/TypingL2.v
preservation_l2_via_l1 and preservation_l2_lift_case now take Semantics_L1.preservation_l1_stmt as an explicit premise.
Check and document the proof boundary .github/workflows/coq-build.yml, CLAUDE.md, EXPLAINME.adoc, PROOF-NEEDS.adoc, TEST-NEEDS.adoc, V1-TO-V2.adoc
The workflow scans _CoqProject-listed Coq files for Admitted., Axiom and Parameter, and checks six results for closed global context. The documents record the retired propositions, counterexamples, proof-status counts and updated test total.
hyperpolymath/ephapax#421: Adds survey evidence that references Semantics.preservation, whose theorem interface this pull request removes.
hyperpolymath/ephapax#418: Documents the preservation claims that this pull request retires as Prop definitions.
Merge Risk: Moderate · previous review dd061
The preservation claims are retired, but the new proof gate can still accept inline unproved declarations. Fix this enforcement gap before merging so the documented axiom-free boundary is protected.

# CLAUDE.md — Ephapax repo agent guidance
## 🛑 Owner directive snapshot (2026-05-27, revised 2026-11-05) — legacy fence plus later L1 regressions
### TL;DR
Ephapax preservation as originally stated in `formal/Semantics.v` is
**provably false** — and that is a *result*, not a defeat:
`formal/Counterexample.v` exhibits a concrete configuration that types,
steps, and lands at an untypable post-state (now 6 lemmas `Qed`, incl. `preservation_false`), which
named an invariant missing from the legacy judgment. So the work is **not**
to close the legacy preservation in `Semantics.v` (no closure exists; it
is retired to `preservation_stmt : Prop`, refuted by `preservation_false`). Nor should the current unrestricted L1
preservation be treated as routine debt: `Counterexample_StepPop.v` and
`Counterexample_PreservationL1.v` refute its supporting claim and capstone.
There is no unconditional L2 preservation theorem; the L2 β-case helpers
are conditional and later counterexampl...

The three open review threads here are addressed in #425 (draft):
r4479628686 (Codex P1) and r4479670504 (CodeRabbit), inline and plural forms.formal/scripts/no-false-gate.sh replaces the line-start grep. It runs a comment- and string-aware token scan for Admitted, admit, give_up, Axiom(s), Parameter(s), Conjecture, Hypothesis/Hypotheses, Variable(s) and Context, and a kernel-bypass scan. It then runs Print Assumptions on every named result (257/257 closed on main), and an independent coqchk -o recheck that fails on any Ephapax axiom. Planted mutants fail it: inline Admitted, Axioms, Parameters, Conjecture, top-level Hypothesis, and Unset Guard Checking. Comment and identifier controls pass. Proof. admit. Qed. is already rejected by coqc.
r4479628695 (Codex P2), manifest. The false clauses are removed from 0-AI-MANIFEST.a2ml:27: "remains Admitted", and the L1 chain "in flight" as debt. The other status surfaces still claiming a live Admitted are corrected too (README, STATUS, ROADMAP, TOPOLOGY, RUST-SPARK-STANCE, PROOF-NEEDS, EXPLAINME, docs/proof-debt.adoc, formal/PROOF-STATUS.a2ml, STATE.a2ml). The .a2ml edits are deletion-only.
…oles, probes, aLib conformer) (#425)
Follow-up to #421 (v2 plan) and #422 (D0/D0b retirement). It closes the
review findings left open on both PRs and lands the W0 wave of the plan.
## No-False gate
`formal/scripts/no-false-gate.sh` replaces the inline `coq-build.yml`
step. That step matched `Admitted.`/`Axiom`/`Parameter` only at the
start of a line and audited only six named results.
The new gate runs four independent checks. Any one failing fails the
gate.
1. **Assumption scan.** Comments and strings are stripped first. It then
matches these at token boundaries: `Admitted`, `admit`, `Admit` (covers
`Admit Obligations`), `give_up`, `Axiom(s)`, `Parameter(s)`,
`Conjecture`, `Hypothesis/Hypotheses`, `Variable(s)`, `Context`.
2. **Kernel-bypass scan.** It runs on whitespace-collapsed source, so a
flag split across lines is still caught. It fails on `Unset
Guard/Positivity/Universe Checking`, `Bypass Check`, `bypass_check` and
type-in-type. Any `Unset` fails, even if a later `Set` restores the
flag.
3. **Assumption census.** `Print Assumptions` runs on every named
result, and each must be closed under the global context. Named results
now include `Definition`/`Fixpoint`/`CoFixpoint` as well as
theorem-class names, so proofs ending in `Defined.` are covered. Results
are found by Coq sentence, so a keyword and its name may sit on
different lines. They are qualified through nested `Module`s; bodies of
a `Module Type`, a functor or a `Module M : S` sealed module are skipped
(`coq-decls.awk`). An unmatched `End` or an unclosed scope fails the
gate. The six headline results must be present.
4. **Independent recheck.** `coqchk -o` fails on any axiom in the
`Ephapax` namespace. It also fails on type-in-type, unsafe (co)fixpoints
or assumed positivity.
**Self-test.** `formal/scripts/test-no-false-gate.sh` has 22 fixtures
and needs no Coq. It runs in CI before the build. The old scanner misses
the split-flag and split-name cases.
**Known limit.** Inside a sealed module or a functor body, check 3
cannot see a standard-library axiom; checks 1, 2 and 4 still cover those
bodies. `formal/` contains no modules today.
**Tree result.** The gate passes: **446/446** named results are closed
(up from 299, because Definitions and Fixpoints are now counted) and
`coqchk` is clean. This includes the four `formal/regress/` files: F2–F6
from the survey, EscapeCex, L2Comp and LetCheck.
## Status docs
The legacy and L1 preservation statements were retired to `Prop`s by
D0/D0b. Every doc and code comment that still called them `Admitted` now
says so. The corrected files are README, STATUS, ROADMAP,
RUST-SPARK-STANCE, TOPOLOGY, PROOF-NEEDS, EXPLAINME,
`docs/proof-debt.adoc`, `docs/testing-and-bench-strategy.adoc`,
`docs/wikis/Home.md`, `spec/FRG-PROFILE.adoc`, and the comments in
`Semantics_L1.v` and `Counterexample_StepPop.v`. `Counterexample.v` has
6 Qed lemmas, not 5.
`spec/FRG-PROFILE.adoc`: the grade-C path now asks for an owner-approved
L1/L2 redesign and replacement theorems, with zero admits; the grade
itself (D) is not reassessed.
The `.a2ml` files only had text deleted, because A2ML is retired.
Idris2 ABI seam: 12 erased postulates are recorded as ASSUMED. They are
jointly consistent because `WellTyped` and `Step` are empty.
## Proof classification (owner ruling, 2026-11-09)
All ephapax soundness statements are theory, with Agda as the source of
truth. Coq becomes the Rocq recheck leg. No result carries a PWG until
an Agda proof exists. Decision D13 (the order of Coq and Agda work) is
added to the plan.
## v2 plan
- The seven Codex findings from #421 are fixed: P9 premise, `Trap`,
`TMu` grades, E0 projections, `i64::MIN` literal, S2b elaboration, P14
branches.
- From CodeRabbit:
- P10 now also owes `config_wf_preserved_v2`;
- E7 checks each `id` specialisation on two inputs.
## W0 wave
**E0: linearity holes in the Rust checker**
- `mark_used` refuses a second use of a linear or consumption-demanding
binding.
- `Ty::is_linear` joins over Prod, Sum, Tuple and List. This
deliberately diverges from Coq `is_linear_ty`; the divergence is
recorded in `docs/coq-rust-bridge/is_linear_ty.adoc`.
- A closure that consumes a captured linear value is rejected.
- Moving a linear value out of a borrow or `Ref` is rejected.
- A wildcard over a linear component is rejected, and so is a duplicate
binder.
- Tuple, list, `fst` and `snd` projections may not discard linear
elements.
- Recursive data is a named `DesugarError`, not a stack overflow.
- Pair patterns now lower to a single core `match`, so a linear pair can
still be destructured.
- **Shadowing.** Every binder is now scoped: a shadowed outer binding is
reinstated when the inner scope closes, and each scope-exit check
inspects its own binding. Before this, `ephapax check` accepted programs
that leak a `let!` value through shadowing. 11 regression cases.
**E1: fail loudly**
- `perform`/`handle` give a `CodegenError` before any module is written.
- Raw `__ffi` gives `TypeError::RawFfiNotSupported`.
- `stdlib/Coproc.eph` and `conformance/valid/ffi_basic.eph` move to
`extern`.
- `@total`/`@pure`/`@comptime` give `ParseError::AnnotationNotEnforced`.
- `-O>0` and `--mode` are rejected, and `--debug` now emits its section.
**Gate files.** `src/ephapax-cli/tests/linearity_holes.rs` and
`fail_loud.rs`.
**Negative corpus.** `conformance/invalid/*` was old v1 syntax and was
rejected only by the parser, so its test passed for the wrong reason.
The five files are rewritten in current syntax; the test now asserts the
specific `TypeError` variant per file.
**X1: probe battery.** `scripts/probe-battery.sh` and
`tests/probes/expectations.tsv` cover 58 rows across check, compile, run
and wasm-run. Against the recorded baseline, E0/E1 turned 22 rows
IMPROVED. The baseline is updated and now reads 58/58 SAME. A compile
timeout or crash in a wasm-run row is now reported as such, not as
`no-module`; `scripts/test-probe-battery.sh` (`just
probe-battery-selftest`) checks this with a stub compiler.
**E6/X8: aLib conformer.** `stdlib/ALib.eph` has 19 scalar ops, and
`src/ephapax-cli/tests/alib_conformance.rs` is the test. The vectors are
pinned at aggregate-library `a877c2e`, SHA-256 checked.
- Result: 90 pass, 0 fail, 13 out of the I32 domain, 53 not implemented.
- The survey's 89/1/13/51 is reproduced exactly at `48b7694`, using a
frozen historical binding set.
- `modulo` is checked to be the signed truncated remainder
(`i32.rem_s`).
- The ratchet fails below 90 passes or on any unlisted FAIL.
## Validation (local, at 743ef88)
- `cargo test --workspace`: 557 passed, 0 failed.
- `scripts/status-gate.sh`: 0 admitted, 554 all-target tests.
- `cargo clippy --workspace --all-targets`: 0 warnings.
- `cargo fmt --check`: clean.
- No-False gate: PASS, 446/446. Gate self-test: 22/22.
- Probe battery: 58/58 SAME. Probe-battery self-test: 4/4.
- `shellcheck -x`: clean on the touched scripts.
## Known and open (not fixed here)
- The interpreter has no `extern` support, so Coproc's interpreter path
is unreachable until E10.
- Pre-existing: Wasm for nested pairs is wrong (`fst((1,(2,3)))` returns
521).
- `scripts/test-probe-battery.sh` is not yet wired into a CI workflow.
- Commits carry the session's SSH signature, not the owner's GPG key.
They need re-signing, or a squash on merge.

#425 (#427)
## Summary
Two commits. The first one repairs CI. The second one closes the review
findings that #425 left open when it merged.
### 1. CI: six workflows have failed at startup since 2026-10-26
Rust CI, Governance, Mirror, Hypatia, Secret Scanner and Scorecard each
failed with **zero jobs** on every run since `3bdc7e4`. The run name was
the file path, which is the sign of a startup failure. So the Rust build
and test gate did not run for #418, #421, #422 or #425.
Cause: `hyperpolymath/standards` moved to `metadatastician/standards`.
GitHub does not follow the redirect for `jobs.<id>.uses`
(standards#1442). The old pin `571cc734` also predates standards#1367,
so the transfer playbook says to repin it.
- All six callers now pin `metadatastician/standards` at `be39f900`
(main HEAD). At that commit, every `uses:` in the six reusables has a
record in the standards `actions.lock`. I checked this from the parsed
YAML.
- `actions.lock` is relocked: the record has the new owner (owner_id
`297579217`, same repo_id), 7 records are added and 6 dead records are
removed. `scripts/check-lock-sync.sh` passes with 0 dangling edges.
- `scorecard.yml`: the job now grants `actions: read`, because the
callee asks for it.
- `secret-scanner.yml`: `secrets: inherit` is removed. The callee
declares no secrets.
- `mirror.yml`: `secrets: inherit` is replaced by the 10 named secrets
that the callee declares.
### 2. Review findings left open on #425#425 merged with 28 unresolved bot threads. Two CodeRabbit commits
(`8dadf82`, `1ec49ee`) landed minutes before the merge, and no Rust CI
ran on them. Most threads were already fixed by those commits. I checked
each one against `main`. These still reproduced and are fixed here:
- **Wasm `match` was always an `i32` block.** A pair destructuring whose
body returns `I64` passed `check`, but `compile` emitted invalid wasm.
Reproduced, then fixed.
- **The bump pointer at `mem[0]` was never set**, so the first heap cell
was written over it. `T(1, 2, 3)` destructured to `167772701`, not
`321`. This is the "nested pairs are wrong" item in the "known and open"
list of #425. Fixed with one data segment. The new test fails without
the fix.
- **Ownership section:** a compound type with a linear component was
emitted as `Unrestricted`. It is now `Linear`.
- **`--debug`** wrote `"mode": "linear"` for every module. It now writes
`per-binding`.
- **Dead code** from the bot commit (clippy warning) is removed.
- **`probe-battery.sh`:** it now requires GNU `timeout`, escalates to
SIGKILL, and keeps the `timeout` verdict.
- **Docs:** the `Coproc.eph` comments claimed that the I32 tag is
widened to i64, which is false. The README run command is now marked
historical.
- **Tests added** for the requested items: 3-tuple projection, I64
destructuring, the value of a 3-field constructor, raw FFI under `let`,
region-exit accounting, compound ownership kinds.
Not fixed here, deferred to rung E10 with a reason in each thread: typed
`extern` in `ephapax run`, and the Coproc tag width. The language has no
I64 literal or conversion yet.
## Validation (local)
- `cargo test --workspace`: 571 passed, 0 failed
- `cargo clippy --workspace --all-targets`: 0 warnings; `cargo fmt
--check`: clean
- `scripts/status-gate.sh --tests` / `--proofs`: OK (568 tests, 0
admitted). `TEST-NEEDS.adoc` is updated from 554.
- No-False gate self-test: 29/29. Probe battery: 57 SAME, 1 SKIP.
Probe-battery self-test: 4/4.
## Notes for the owner
- **Blocker: the repo Actions policy.** On this PR's first push, the
four standards callers that run on PRs (Rust CI, Governance, Secret
Scanner, Hypatia) still fail with `startup_failure` and zero jobs.
Before this change they failed earlier, as an unparsed file path. Now
GitHub resolves the new coordinate and then refuses it at plan time. The
transfer playbook (standards
`docs/compliance/repo-transfer-to-enterprise-playbook.adoc` §4)
describes that symptom for a caller on "selected actions". Please add
`metadatastician/standards/.github/workflows/*@*` in Settings → Actions
→ General. Also check that the actions the reusables use are allowed:
canon is standards `config/settings/actions-allowlist.json`. Or run
`scripts/widen-actions-allowlist.sh hyperpolymath/ephapax --apply` from
a standards checkout with admin access. Then re-run the failed runs. I
cannot read or change that setting from this session, and the run page
that gives the exact reason is not reachable from here.
- The commits carry the session SSH signature, not your GPG key. They
need a re-sign or a squash merge.
- No `formal/` file is changed.

Summary
This implements plan rung P0 with the owner-ratified D0 and D0b (2026-11-05; recorded in #421).
Three refuted statements were
AdmittedalongsideQedrefutations, so the Coq build could deriveFalse:Semantics.preservation, refuted byCounterexample.v;step_pop_disjoint_from_type_l1, refuted byCounterexample_StepPop.v;preservation_l1, refuted byCounterexample_PreservationL1.v.This PR retires all three to
Propstatements. It does not close them: no refuted statement is proved.formal/changesSemantics.v:Theorem preservation … Admitted.becomesDefinition preservation_stmt : Prop. The roughly 700-line partial proof script and its closure-status notes are removed; they remain in git history.Counterexample.v: newpreservation_false : ~ preservation_stmt(Qed). The witnesses are unchanged.Semantics_L1.v:step_pop_disjoint_from_type_l1andpreservation_l1become…_stmt : Prop.Counterexample_StepPop.vandCounterexample_PreservationL1.v: the_FALSEtheorems are restated as~ …_stmt, with the same proofs.TypingL2.v:preservation_l2_via_l1andpreservation_l2_lift_casenow takepreservation_l1_stmtas an explicit hypothesis. Before, they silently depended on the falseAdmitted.CI

The owner asked me to draft these:
Owner action outside this repo: the memory entry
