Update 2026-11-10: merged with main after #195

#195 gated the receipt-boundary theory in CI (Agda 2.8.0.2, Lean and Rocq legs, receipts and a correspondence section), so main wins in every conflict (merge commit 0bf40aa):

• proof-safety.yml and PROOF-STATUS.adoc: main's versions.
• scripts/check-agda-proofs.sh: main's 2.8.0.2 pin. This PR's 2.7.0.1 pin would make main's theory job refuse the check.
• docs/T-RECEIPT-CORRESPONDENCE.adoc: dropped, because main's PROOF-STATUS carries the same record.

This PR now changes only docs/proof-debt.adoc: the table of the 2 deliberate escape hatches (proofs/coq/admitted_stub.v:11, proofs/lean/sorry_stub.lean:7). Both are negative fixtures that tests/protocol_contract.rs::checked_in_negative_proofs_are_detected requires, so they stay intact.

The Dependency audit failure on the old head (RUSTSEC-2026-0459) is fixed on main by #199, which this merge brings in.

What (original; all but proof-debt.adoc superseded by #195)

• proof-safety.yml: new agda and rocq jobs. Superseded by proofs: check the receipt-boundary theory in Agda, Lean and Rocq, and gate it in CI #195.
• check-agda-proofs.sh: pin moved to 2.7.0.1. Reverted to main's 2.8.0.2.
• docs/proof-debt.adoc: both hatches recorded as deliberate negative fixtures. Still in this PR.
• docs/PROOF-STATUS.adoc: grade wording. Superseded by proofs: check the receipt-boundary theory in Agda, Lean and Rocq, and gate it in CI #195.

Summary

Summary by CodeRabbit

• Quality Checks
  • Added automated Agda and Rocq proof checks to the continuous integration process, including verification that expected proof obligations are closed.
• Documentation
  • Clarified which proofs have been checked, which remain pending, and how proof status is assessed.
  • Documented the relationship between the Agda statement and its Rocq and Lean re-proofs.
  • Clarified that negative fixtures and unfilled scaffolding are not counted as verified proofs.

The pull request adds Agda and Rocq proof checks to CI, records the Agda version pin, documents the T-RECEIPT proof correspondence, and updates proof status and proof-debt records.

Changes: Proof verification and status

Layer / File(s)	Summary
Pinned Agda and Rocq CI checks scripts/check-agda-proofs.sh, .github/workflows/proof-safety.yml	The script now expects Agda 2.7.0.1. The workflow verifies the Agda archive digest before running the script, and adds a Rocq job that compiles ReceiptBoundary.v and checks for exactly three Closed under the global context lines.
T-RECEIPT correspondence record docs/T-RECEIPT-CORRESPONDENCE.adoc	The new document compares the Agda, Rocq, and Lean statements and proof terms. It records the differences and the conditions for Rocq and Lean to leave BRIDGE-PENDING.
Proof status and fixture accounting docs/PROOF-STATUS.adoc, docs/proof-debt.adoc	The documents describe the CI evidence requirements, distinguish runtime confidence from proof witness grade, and record that negative fixtures do not count toward proof counts or grades. They also identify unfilled Idris ABI templates as scaffolding, not verified proofs.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Other

Possibly related PRs

• hyperpolymath/echidnabot#195: It changes the same Agda check and workflow, but pins Agda to 2.8.0.2 rather than 2.7.0.1.
• hyperpolymath/echidnabot#191: It adds the Agda and Rocq theory sources and the original Agda check that this pull request wires into CI.

Merge Risk: Low · up to 92bb6

The proof checks add useful verification, but Rocq toolchain reproducibility and status-update wording need bounded follow-up. Current Rocq proofs are closed; checking each theorem independently would strengthen regression protection. These concerns do not establish a production failure.

Full details: Title check

Explanation

The title names the main change: a CI gate for T-RECEIPT (the new Agda and Rocq jobs in proof-safety.yml) and the recording of the two deliberate negative-fixture hatches in proof-debt. The summaries and objectives confirm both parts. The title is specific and accurate, and it does not describe anything absent from the changeset.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 1 files. (4 skipped: 4 unsupported.)

Dependency audit is red, but not because of this PR.

cargo audit reports RUSTSEC-2026-0459, libsqlite3-sys 0.30.1 via C SQLite (fix: upgrade to ≥0.39.0). This PR doesn't touch Cargo.toml or Cargo.lock. The same check passed on main at 06:14Z today, so the advisory reached the database after that, and the next main run will fail the same way.

No fix exists yet. libsqlite3-sys is pulled in by sqlx = "0.8.1" (features sqlite, postgres), and the 0.8 line pins libsqlite3-sys 0.30. Reaching ≥0.39 means an sqlx major upgrade. That needs its own PR, built from a gitbot-fleet checkout because of the shared-context path dependency, and it doesn't belong in this proof-CI change.

Review comments at @.github/workflows/proof-safety.yml:
- Around line 61-65: Update the “Install the distribution Rocq (Coq) kernel”
step in the proof-safety workflow to install and verify a pinned toolchain
version and record its installed digest; add the required deviation record to
both the workflow and the proof-status file, using the repository’s established
format.
- Around line 75-76: Update the proof-safety workflow check so it verifies
closure separately for receive_with_soundness, no_unconditional_reflection, and
no_soundness_for_empty_token. Associate each theorem’s Print Assumptions result
with its own query and require that result to report a closed term, rather than
relying on a total count that another query could satisfy.

Review comments at @docs/PROOF-STATUS.adoc:
- Around line 174-175: Update the status-evidence rule near the Agda and Rocq
job description so each obligation’s status can move when its own required
evidence is observed; do not require Agda or Rocq output for a status supported
by other evidence, such as a Creusot check satisfying E-RECEIPT.
