Summary
Summary by CodeRabbit
Documentation
Updated project, roadmap and proof materials to distinguish research goals from established results. They now state that legacy and unrestricted L1 preservation claims are refuted, no unconditional L2 preservation theorem is established, and L3 results are limited to matching rule pairs.
Clarified the scope and limitations of formal artefacts, including that they do not establish general language soundness or implementation refinement.
Updated proof and test status documents to reflect current proof boundaries and outstanding redesign work.
Chores
Updated status checks and references to use .adoc documents; proof-count and test-count gates remain separate.
The pull request updates formal proof declarations and project records to distinguish refuted preservation claims, conditional or scoped results, and open redesign work. The status-gate workflow and script now refer to the .adoc proof and test status documents.
Changes: Preservation status and claims
Layer / File(s)
Summary
L1 substitution and counterexample boundary formal/Semantics_L1.v, formal/Counterexample*.v, formal/L1ChoreoExperiment2.v, formal/TypingL1.v
The L1 substitution declarations add an explicit no-exit premise, and unrestricted region-liveness helper declarations are removed. Comments distinguish specific counterexamples from general preservation results.
Proof-status records and evidence limits .machine_readable/6a2/STATE.a2ml, EXPLAINME.adoc, PROOF-NEEDS.adoc, formal/PROOF-STATUS.a2ml, docs/proof-debt.adoc
Proof records distinguish refuted statements, conditional helpers, scoped results and open redesign work. They document checker boundaries, proof-grade criteria and build status.
Historical proof plans and design records formal/PRESERVATION-DESIGN.adoc, formal/PRESERVATION-HANDOFF.adoc, formal/ESCALATION-4.8-leaf-rule-region-liveness.adoc
Earlier proof plans and closure material are identified as historical. The documents qualify their claims against the counterexamples and current proof boundaries.
Project status, roadmap and public claims CITATION.cff, README.adoc, ephapax-linear/README.adoc, ROADMAP.adoc, STATUS.adoc, docs/vision/*, docs/wikis/Home.md
Project descriptions distinguish design goals from established results. They describe L1 and L2 proof limits, the scope of L3 results, and limits on implementation-refinement claims.
Contributor policies and next actions CLAUDE.md, V1-TO-V2.adoc, TEST-NEEDS.adoc
Contributor guidance directs work towards sound replacement theorems with explicit boundaries and retained counterexamples. The checklist says not to treat refuted markers as routine proof debt.
The documentation clarifies preservation limits without establishing broader soundness claims. Three previously identified documentation issues remain open; these are bounded concerns suitable for owner follow-up rather than evidence of a runtime regression.

# CLAUDE.md — Ephapax repo agent guidance
## 🛑 Owner directive snapshot (2026-05-27) — legacy fence plus later L1 regressions
### DO
2. **DO continue the layered build without overclaiming:**
- L1 (`TypingL1.v` + `Semantics_L1.v`): the judgment and helper
lemmas exist, but the unrestricted preservation claim is refuted.
Replacement design is open; its theorem boundary must be explicit.
- L2: modality is mechanised and `linear_to_affine` is Qed, but
no unconditional `preservation_l2` theorem exists. Treat the
β-case lemmas as conditional and retain both L2 counterexamples.
- L3 (`Echo.v`): calculus and selected matching-rule preservation
results are Qed; do not generalise them to L1/L2.
- L4: scaffold/design only; no preservation theorem.

Remove the contradictory preservation claim.
The opening proof-track summary still says that v2 “re-derives preservation per layer”. The newly revised introduction and the status section at Lines 227–249 say the opposite: unrestricted L1 preservation is refuted and no unconditional L2 theorem exists. The nearby claim that each layer has its own preservation theorem repeats the same error. Describe per-layer preservation as a redesign target, not a completed result. (raw.githubusercontent.com)

Give the full path in the cross-layer check.
The instruction at CLAUDE.md:229 names PRESERVATION-DESIGN.adoc without its directory. No file with that name exists at the repository root, so an agent that resolves the name from the root does not find the document. The document is at formal/PRESERVATION-DESIGN.adoc. Use the full path, as the same file already does at lines 62, 71, and 170.

The status-gate path fix and the doc corrections already landed on main,
so those rows are marked fixed. The evidence was re-checked at 10339b3
with identical Print Assumptions output. The environment inconsistency
is still unrecorded on main.

#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.
