Modeling pattern (established in initial slate): SPARK can't reason about
file IO, async/tokio, strings, or cryptographic primitives, so each
companion abstracts those into boolean inputs at the boundary and proves
only the decision tree *above* the IO/crypto layer. Concrete contracts
focus on totality + cap-at-bad-state monotonicity (cap-at-Reject for
axiom_tracker, cap-at-Tampered for solver_integrity, cap-at-malformed
for certificates).

Rationale: idiomatic Julia, schema evolution propagates automatically via regenerated bindings. Risk acknowledged: CapnProto.jl is pre-1.0 and the RPC layer may need patching; patch upstream if required rather than switching approaches. Zig shim (Option B) remains scaffolded in ffi/zig/src/capnp_bridge.zig as a fallback if CapnProto.jl proves unworkable in practice."

After the user's `merge to single main + complete these things`
directive, both proof targets were attacked. Outcome:

Phase 1.3 (#4): structural scaffolding LANDED in echo-types commit
e0f67cb on main. New module Ordinal.Brouwer.Phase13 defines
recursive `_≤′_`; bullseye lemma `osuc-mono-≤′ p = p` compiles as
identity. Strict version + ≤′-zero + oz<′osuc all land. ≤′-refl
for the `olim f` case is the documented obstacle (`f-in-lim′`'s
`f n = olim g` sub-case needs mutual-with-trans or accessibility
strengthening).

Unbudgeted wf-<ᵇʳᶠ_ (#5): rank function shape LANDED in echo-types
same commit. New module Ordinal.Buchholz.RankBrouwer defines
`rank : BT → Ord` exactly as recommended. Transport theorem
deferred (couples to Phase-1.3 `⊕-mono-<-right` and Phase-2.2
`rank-mono-<ᵇ`).

Both modules pinned in Smoke.agda, wired into All.agda. Full suite
exits 0 under `--safe --without-K`. No postulates introduced.

Important context discovered mid-session: a prior dropped stash
attempted the same recursive `_≤_` *replacing* the data definition
and hit the same `f-in-lim` obstacle plus an implicit-arg-inference
issue with downstream lemmas. Current landing avoids the inference
issue by defining `_≤′_` alongside the original data `_≤_` rather
than replacing.

Echo-types main updated with two commits: e0f67cb (the Agda
modules) + 3799cb7 (handoff doc EOD update).
