proofs: honest prover gate — absent prover = fail, z3 expect-checked, Print Assumptions gated, Agda 4/4 --safe (4b–4d) - #172
Merged
Conversation
… Print Assumptions gated, Agda 4/4 --safe (4b–4d)
Four defects made the gate able to say green without checking:
- verify-all-provers.sh printed "skipped" for an absent Isabelle or Mizar and
still said ALL-PROVERS-GREEN (four of six provers); a listed Agda module that
was missing on disk was silently skipped too.
- proofs/z3/verify.sh ran `z3 cno_properties.smt2` — a file that does not exist —
and CI wrapped it in `|| true`; the only live z3 check was an exit code, which
is 0 for sat AND unsat.
- Nothing ran Print Assumptions anywhere, so "closed under the global context"
was prose.
- CI type-checked 2 of the 4 Agda modules and EchoBridgeCNO.agda carried no
--safe pragma of its own.
Changes:
- proofs/verify-all-provers.sh: Isabelle/Mizar absent -> fail=1; missing Agda
module -> fail; EchoBridgeScaffold added; z3 via the expect-checker.
- proofs/z3/verify.sh: generic expect-checker — every (check-sat) must carry
`; expect sat|unsat` and z3's verdicts must match in order; fails on unknown,
(error, missing annotation, no files, z3 rc != 0.
- proofs/coq/audit/Assumptions.v + proofs/coq/check-assumptions.sh: the 17
theorems PROOF-STATUS names must print Closed under the global context;
--control proves the gate rejects landauer_limit_positive (kB_positive).
- proofs/tests/gate-selftest.sh: 14 cases (stubbed toolchains + real-z3
mutants), each negative asserting its reason string.
- proofs/agda/EchoBridgeCNO.agda: {-# OPTIONS --safe --without-K #-}.
- .github/workflows/proofs.yml: coq job runs the gate + control; agda job checks
4 modules; z3 job runs the checker without `|| true` plus the self-test.
- Justfile: build-agda 4 modules; verify-z3 no skip-as-pass; verify-coq runs
the gate; new verify-gate-selftest in verify-all.
- PROOF-STATUS.adoc: Agda section matches CI; assumptions claim is the measured
17/17-closed fact; census (109/182 closed) tracked in #171.
Measured locally (2026-09-23): self-test 14/14; reverting the Isabelle fix
flunks exactly case B; blinding the z3 comparison flunks exactly E/G/K/N;
assumptions gate 17/17 closed, control rejects naming kB_positive, vacuous and
renamed audit files fail; agda 2.6.4.3 --safe --without-K passes all 4 modules;
actionlint clean; actions.lock coverage complete.
Refs #171. Phase 4b–4d of the residual-evidence-types ultraplan.

…nside the canonical gate `just verify` -> proofs/verify-all-provers.sh built Coq and printed ALL-PROVERS-GREEN without ever running proofs/coq/check-assumptions.sh, so the canonical gate could say GREEN on a theorem resting on an axiom: the same "guard asks a different question" defect this PR cures elsewhere (CodeRabbit's Major on the first commit). - verify-all-provers.sh: after a successful Coq build, run check-assumptions.sh and check-assumptions.sh --control; either failing sets fail=1 with its own reason line. - gate-selftest.sh: the coqc stub now answers `Print Assumptions` faithfully (Closed for every audited theorem, `Axioms: kB_positive` for the control's target), so case A exercises the audit; cases O (every theorem reports an axiom) and P (the control's target reports closed) prove the gate turns red for each. 16/16 locally; with the previous gate exactly O and P fail (meta-mutant), and I still passes after them. - PROOF-STATUS: 14 -> 16 cases; the audit is named as part of the canonical gate. Real prover, Coq 8.20.1: `just verify-coq` -> ASSUMPTIONS-CHECK OK 17/17, ASSUMPTIONS-CONTROL OK (landauer_limit_positive rejected naming kB_positive).

Why
Phase 4b–4d of the residual-evidence-types ultraplan (absolute-zero is upstream of echo-types, hence of residual). Four defects let the prover gate say green without checking:
echo "… (skipped)", thenALL-PROVERS-GREENon 4 of 6 proversfail=1; a listed Agda module missing on disk also failsz3 cno_properties.smt2(file does not exist) under|| true; the live check was z3's exit code, 0 for sat and unsat(check-sat)must carry; expect sat|unsatand the verdicts must match in order; fails onunknown,(error, missing annotation, no files, rc≠0Print Assumptionsran anywhere; "closed under the global context" was proseproofs/coq/check-assumptions.shover the 17 theorems PROOF-STATUS names, in the Coq CI job, with a--controlthat must rejectlandauer_limit_positive(rests onkB_positive)EchoBridgeCNO.agdahad no--safepragmaAlso:
Justfileverify-z3no longer skips-as-passes;verify-coqruns the gate;verify-allruns the self-test. PROOF-STATUS: the Agda section now matches CI, the assumptions claim is the measured fact (17/17 closed, gated), the census pointer is #171.Evidence (measured locally 2026-09-23, before push — the owner may merge before CI reports)
Gate self-test
proofs/tests/gate-selftest.sh— 16/16, each negative asserting its reason string (stub PATH,HOMEoverridden because the gate prepends~/.elan/bin):Meta-mutants (does the suite itself bite?) — reverting the Isabelle line to
(skipped)flunks exactly case B; replacing the checker's comparison withgot="$expected"flunks exactly E, G, K, N. Both restored, suite green again.Assumptions gate —
ASSUMPTIONS-CHECK OK: 17/17 theorems closed under the global context;--control:landauer_limit_positive rejected, naming kB_positive; an empty audit file fails as vacuous; a renamed theorem fails on coqc exit 1. Full census for #171: 182 top-level theorems, 109 closed, 73 axiom-dependent.Agda —
agda 2.6.4.3 --safe --without-KpassesCNO,OND,EchoBridgeScaffold,EchoBridgeCNO. ⚠ CI runs Agda 2.6.3 / stdlib v1.7.3; the two newly-checked modules have not been run at that version locally (Axiom.Extensionality.Propositionalexists in v1.7.3). A red there is a finding (issue with acceptance criteria), not a revert of the gate.Workflow —
Bun.YAML.parseok (4 jobs);actionlintclean;gh actions-lock --verify-local: all 16 workflows have complete lockfile coverage (nouses:line changed).just verify-z3,verify-coq,verify-gate-selftest,build-agdaall rc=0.Deliberately left out of this PR

(Same defect class; separate small change if wanted.)EchoCNOBridgedoes not exist)" item was wrong:proofs/agda/README.adoc:39cites echo-types'proofs/agda/EchoCNOBridge.agda, which exists on echo-types main. Not changed.Merge policy
Auto-merge (squash) goes on only when every check is green (owner ruling 2026-09-22). Any pre-existing red gets a triage issue, not a merge-over. Refs #171; #170 (Scorecard highs) is unrelated but its
code_scanningrule may now evaluate on this PR for the first time — if it blocks, that belongs on #170.Second commit (
b0a08cc) — CodeRabbit's Major on the first commit was right: the canonical gateproofs/verify-all-provers.shbuilt Coq but never rancheck-assumptions.sh, sojust verifycould print ALL-PROVERS-GREEN on an axiom-bearing theorem (the same defect class this PR cures elsewhere). The gate now runs the audit and its--controlafter a successful build, each with its own reason line; the self-test'scoqcstub answersPrint Assumptionsfaithfully (Closed for the 17 audited theorems,Axioms: kB_positivefor the control's target) and cases O/P prove the gate turns red for each audit mutant. Self-test 16/16; against the previous gate exactly O and P fail. Real prover locally (Coq 8.20.1): ASSUMPTIONS-CHECK OK 17/17, ASSUMPTIONS-CONTROL OK.
