# Proof verification CI. Runs the LIGHTWEIGHT provers that are fast and reliable
# on a standard GitHub runner — Coq (both pillars, all 14 theories), Agda (CNO +
# OND), and Z3 (CNO + OND bounded instances). Each is an INDEPENDENT job, so one
# flaking never blocks the others.
#
# The heavy provers (Lean + multi-GB Mathlib, Isabelle ~1.2 GB, Mizar i386 + MML,
# Idris 2 from source) are NOT run here — they are covered by the local/container
# gate `proofs/verify-all-provers.sh` (ALL-PROVERS-GREEN). See PROOF-STATUS.adoc.

# NOTE: an Agda job was attempted but removed. Ubuntu's `agda-stdlib` package
# ships the sources without a usable library manifest, and the apt Agda/stdlib
# pairing on the runner would not resolve `standard-library` reliably across
# four different setups (register / -i include path / synthesized .agda-lib).
# Rather than ship a flaky red job, Agda is verified via the local/container
# gate `proofs/verify-all-provers.sh` (which type-checks CNO.agda + OND.agda).
# To re-add it, a pinned Agda toolchain (e.g. a Nix/setup-agda action with a
# matching agda-stdlib) is the reliable route — not apt.
