+/-! ## Set-discharge composition soundness
+
+Formalization of the abstract set-discharge invariant across `CheckEnv` leaf
+claims and recursive `ix_aggr` pair folds (flat, structural, and cross-binding):
+
+1. Every base leaf claim `(S, A)` in the abstract model satisfies `S ∩ A = ∅`
+   (`disjoint`), checks every owned subject `x ∈ S` under its dependencies
+   (`checked`), and ensures every direct dependency `y` of an owned subject
+   `x ∈ S` lies in `S ∪ A` (`closed`). (In the Aiur circuit, `env_walk_leaves`
+   guards `S ∩ A = ∅` by interned store pointer, which holds under honest
+   content-addressed interning; note that `aggrDerivation_sound`'s root closure
+   and validity conclusions use only `checked` and `closed`, not `disjoint`.)
+2. Every binary join `(S_L, A_L), (S_R, A_R) ↦ (S_out, A_out)` unions the
+   subject sets (`S_out = S_L ∪ S_R`) and discharges an assumption only
+   against the opposite child's subjects (`A_L ∖ A_out ⊆ S_R` and
+   `A_R ∖ A_out ⊆ S_L`).
+3. By induction over any aggregate derivation tree, every subject `x ∈ S` at
+   any node was checked at some base leaf, every discharged assumption belongs
+   to `S` and was checked at some base leaf, and when `A = ∅` at the root the
+   subject set `S` is closed under dependencies so well-founded induction along
+   the acyclic content-addressed dependency relation yields unconditional
+   validity for every `x ∈ S`.

-  `ix check <path>`: typecheck a serialized `.ixe` environment through
-  the Ix Rust kernel. Path is positional and required.
-
-  Two kernel modes:
-
-  - Default (Meta): kernel runs with metadata fields populated (Lean.Name,
-    binder info, mdata). Supports `--ns` / `--consts` / `--consts-file`
-    for seed filtering and `--fail-out` for bisect-loop workflows. Seeded
-    meta checks are SUBJECT-ONLY: each seed is checked with its deps
-    lazily ingressed but trusted, not re-checked.
-  - `--anon` (metadata-free): the env is loaded via `Env::get_anon` —
-    `named`/`names`/`comms` sections are discarded at load time, never
-    reaching the kernel. The kernel's typechecking logic structurally
-    cannot read metadata (`M::MField<T>` is `()` in Anon mode); progress
-    labels are `@<hex>` addresses, not names.
-
-    Without a filter, every kernel-checkable address is checked (whole
-    env). With `--consts` / `--consts-file`, the named constants are
-    checked together with their full dependency closures. Add
-    `--skip-deps` for a subject-only check (deps trusted). On a bound
-    artifact, both also check the closure of the binding's role records
-    and certificates: role admission assumes them, so a verdict on any
-    constant that reaches an admitted role rests on them.
-    `--ns` prefix filtering stays meta-only.
-
-  Direct Lean → kernel typechecking (compile-and-check from source) is
-  available via the `rsCheckConstsFFI` API for tests
-  (`Tests/Ix/Kernel/Tutorial.lean`, `Tests/Ix/Kernel/CheckEnv.lean`).
-  Use `ix compile <file>` first, then `ix check <output.ixe>`.

   `ix compile-lean <path.lean> [--out out.ixe]`: compile a Lean file's

+  (`Ix.CompileM.compileAndFinalize`): the source contracts are prepared, the
   input is canonicalized (`Ix.CanonM`), compiled and checked by
   `compileReport`, its accounting and resources are checked; the role support,
   evidence and binding are added (`Ix.RoleBinding.Compile.finalize`, which
   checks the finalized artifact again), and the artifact is serialized
   (`Ixon.serEnv`) and written atomically.
 
-  The certified compiler runs at the default sharing limits, which the theorem
-  fixes: `--sharing-limits` or `IX_SHARING_LIMITS` is refused, unless
-  `--streamed` is given. `--streamed` selects the streamed pipeline
-  (`Ix.CompileM.compileLeanInputValidated`), which is uncertified: its fold is
-  `compileReport`'s (`Ix.Cert.Hybrid`), but its streamed canonicalization,
-  graph, ground filter and condensation are only tested to be. It is kept for
-  comparison.
-
-  `--rust-check` additionally compiles the same prepared constants through
-  the Rust FFI compiler (`rs_compile_env_bytes`). Lean decodes that raw
-  artifact, finalizes it with the Rust backend, then serializes it with
-  `Ixon.serEnv`. The ALIGNED gate compares these finalized bytes with the
-  selected Lean path's output. Rust's serializer participates in the raw
-  handoff; both final envelopes use Lean serialization. This is byte-parity
-  evidence for the selected input, not a universal refinement or
-  value-preservation proof.
-
-  Exit codes: 0 success (including an explicitly allowed partial output,
-  and aligned when checked); 1 pipeline error, an unallowed compilation failure,
-  or divergence; 2 usage. The Lean output is written before `--rust-check`,
-  so a later divergence leaves that output on disk.

-# The Lean pipeline's validated post-steps
-
-`Ix.CompileM.compileLeanInput` compiles and serializes; it does not validate
-resources, so the compiler does not import `Ix.Resource.Validate` (and with it
-the validator's typing half, `Ix.Resource.typeCheck`). An input that carries semantic contracts, or
-a compile against a resource profile, is emitted only after this post-step:
-the requested closure must be complete (no recorded failure), and the
-compiled environment must validate (`Ix.Resource.validate`, against the given
-profile or the environment's standard one). Every result then checks original
-input publication/failure accounting from the compiler's retained facts, and
-the compile's report as the pure compiler checks its own (`reportPostStep`).
-`ix compile-lean`, `ix validate-lean` and the Lean backend of artifact support
-use the validated wrappers before emission. Bare compileLeanInput/compileLeanConsts
-remain unvalidated.
-This post-step does not authenticate caller-supplied Node maps.

-    structure optimization does NOT elide the enum to just `String`. With
-    only one ctor + one field, `hasTrivialStructure?` fires and the runtime
-    representation becomes identical to `String`, which breaks any FFI that
-    allocates a heap ctor. See
-    `refs/lean4/src/Lean/Compiler/LCNF/MonoTypes.lean:20-28`.

-
-    Implemented in `src/ffi/kernel.rs::rs_kernel_check_consts`. Note: this
-    used to be gated behind the `test-ffi` Cargo feature. It is now part
-    of the production build so `lake exe ix check` can drive it directly.
-
-    The trailing `Bool` toggles ephemeral progress printing on the Rust
-    side:
-    - `false` (verbose): every constant is logged on its own line with
-      elapsed time and `def_eq` depth — ideal for small, targeted batches
-      where every result matters.
-    - `true` (quiet / ephemeral): the current `[i/N] name ...` label is
-      rewritten in place, and only slow constants (>=7s by default), unexpected
-      passes/failures, and ungrounded compile errors are promoted to
-      persistent lines. Ideal for full-env runs where thousands of fast
-      constants would otherwise swamp the log. Parallel quiet mode also
-      prints periodic done/total, rate, ETA, and oldest in-flight
-      constants. Tune with `IX_KERNEL_CHECK_PROGRESS_MS`,
-      `IX_KERNEL_CHECK_SLOW_MS`, `IX_KERNEL_CHECK_ACTIVE_SLOW_MS`, and
-      `IX_KERNEL_CHECK_INFLIGHT`.
-
-    Results come back in input-array order — the caller pairs each
-    `results[i]` with its `names[i]`. We pass `Lean.Name` structurally
-    (rather than shipping `name.toString` strings) because Lean's
-    default `toString` wraps non-identifier components in `«…»`, and
-    round-tripping that through a Rust string parser was brittle:
-    names like `Lean.Order.«term_⊑_»` failed lookup against the
-    kernel's unescaped `Lean.Order.term_⊑_` key. Rust decodes each
-    `Lean.Name` structurally via `decode_name_array`, so the kernel
-    lookup is an exact structural match. -/

+This module defines the structural predicates and executable boolean checkers
+for pre-lowering fiber safety on a closure `(sub, blocks)` at an artifact and
+role table `(ixe, t)`, and connects `prepareSourceCollapsedAt` to the collapsed
+trace invariants in `Ix.Cert.SourceTrace`, `Ix.Cert.SourcePrelude`, and
+`Ix.Cert.SourceReplay`:
+
+* `GroupIntraInjective` and `checkGroupIntraInjective`: within every inductive
+  and definition group of `groupsOf sub blocks`, `Key.subst` at
+  `fiberAliasAt ixe (roleAtMap t)` maps the group's declared constants to
+  pairwise distinct keys (`Nodup`);
+* `HintsAgreeAt` and `checkHintsAgreeAt`: every definition in `sub` has its
+  nominal reducibility hint matching `fiberHintsMap ixe` at its substituted key;
+* `FiberAliasSafe`, `checkGroupFiberSafe`, and `checkGroupFiberSafe_sound`: the
+  combined executable checker and its soundness theorem;
+* `step_fresh_or_beqF`, `alias_fresh_or_beqF`, `collapseRead_fresh_or_beqF`,
+  and `prepareSourceCollapsedAt_trace`: every step in a successful collapsed
+  trace is either a fresh declaration/block or an exact structural match
+  (`Declaration.beqF` / `BlockRead.beqF`) with an already-kept declaration or
+  block, while `StableOwned`, `OwnerExact`, `KeptNoBasis`, `declsGoodB`,
+  `bundleDisjointB`, `evidenceGoodB`, and `keepsPrelude` all hold.

+are strict, and such an axiom declines.
+
+The kernel decides what is admitted and lists it. Its entries under

+`checkBytesTieredUsingUnder`, run by `Artifact.checkConditional` and
+`checkTieredConditional`) refuse a role table that leaves an axiom role
+unbound (`Admission.admitAxiomPolicy`) and return the user axioms of the
+declarations they ran over. What is left here is the host's part:
+
+* `requireAxiomRoles`: the kernel's role-table check, `admitAxiomPolicy
+  .allowUser`, on the artifact's binding, with the host's message, before a
+  driver checks any declaration. The record-by-record drivers
+  (`Ix/KernelCheck/{Step,Pool}.lean`, through `annotDeclStepWithUserAxioms`)
+  never reach admission, so every driver runs it first
+  (`CheckLeanCmd.prepareInput`, `CheckIxe.run`).
+* `addresses`, `ofDecls`: the input keys of the kernel's list, for the

-  ShardMap: A concurrent hashmap with sharded locks for parallel access.
-
-  This is a Lean equivalent of Rust's DashMap, providing O(1) concurrent
-  read/write access with reduced lock contention through sharding.
-
-  ## Thread Safety
-
-  - All single-key operations (`insert`, `get?`, `remove`, `modify`, etc.) are atomic
-    and thread-safe.
-  - Aggregate operations (`size`, `toArray`, `fold`, `toList`, `toHashMap`) iterate
-    over shards non-atomically - they may observe an inconsistent view during
-    concurrent modifications.
-  - `clear` is not atomic - shards are cleared sequentially.
-
-  ## Performance Characteristics
-
-  - Uses power-of-2 sharding with bit masking for O(1) shard selection.
-  - Each shard uses SharedMutex for reader-writer semantics (concurrent reads,
-    exclusive writes).
-  - Cache line padding prevents false sharing between adjacent shards.
-  - Hash mixing distributes keys more evenly across shards.
-  - Default 256 shards provides good parallelism for most workloads.
-  - `insertMany` parallelizes updates across shards for 10-20x speedup on bulk inserts.
-
-  ## Usage
-
-    let map ← ShardMap.new (shardBits := 6)  -- 64 shards
-    map.insert key value
-    let val? ← map.get? key
-
-    -- Bulk insert for better performance
-    map.insertMany #[(k1, v1), (k2, v2), ...]
-
-    -- Atomic read-modify-write
-    let result? ← map.modifyGet key fun v => (computeResult v, updateValue v)

+/-! # The theorems of the entries that admit user axioms
+
+The entries under an axiom policy (`checkConstantsUnder`, `checkBytesUnder`,
+`checkConstantsTieredUnder`, `checkBytesTieredUsingUnder`;
+`IxC/Kernel/Admission.lean`, `IxC/Kernel/Admission/Tier.lean`) return the
+environment together with the user axioms the accept is conditional on. The
+user-axiom entries (`checkBytesWithUserAxioms`, `checkConstantsWithUserAxioms`,
+`checkConstantsTieredWithUserAxioms`, `checkBytesTieredUsingWithUserAxioms`)
+are their environments at `allowUser`.
+
+* **At `strict` they are the certified entries** (`checkConstantsUnder_strict`,
+  `checkBytesUnder_strict`, `checkConstantsTieredUnder_strict`,
+  `checkBytesTieredUsingUnder_strict`), so every theorem of
+  `Ix.Kernel.Admission.Theorems` and `.TierTheorems` is a theorem about them.
+* **T1: an accept with no user axioms is the certified entry's accept**
+  (`checkConstantsUnder_strict_of_nil`, `checkBytesUnder_strict_of_nil`,
+  `checkConstantsTieredUnder_strict_of_nil`,
+  `checkBytesTieredUsingUnder_strict_of_nil`), at every policy: over records
+  that declare no user axiom the fold is `checkDecls`
+  (`Cached.checkDeclsUnder_eq_checkDecls`). In particular such an accept has a
+  model (`checkBytesUnder_has_model_of_nil`, `UserAxioms/Model.lean`), and a
+  receipt of the user-axiom entry whose list is empty is a receipt of the
+  certified entry (`Ix.RoleBinding.Artifact.ReceiptConditional.toReceipt`,
+  `TierReceiptConditional.toTierReceipt`).
+* An accept of a user-axiom entry is exactly an accept under `allowUser` with
+  some list (`checkBytesWithUserAxioms_ok_iff`, ...).
+
+This file is a `module`, so that a host's compiled code can build the certified
+entry's receipt from an accept that lists no user axiom (a `module` imports
+only modules). It imports no theorem module: the theorem that needs one, the
+model of such an accept, is `UserAxioms/Model.lean`.
+
+Every statement holds at every content hash `hash`. An accept that lists user
+axioms is conditional on them; no model is claimed for it here. -/

+# The axiom policy: the strict fold and the fold that admits user axioms
+
+The certified fold `checkDecls` (`IxC/Kernel/Cached/Installed.lean`) admits an
+axiom only as one of the pinned standard axioms (`propext`,
+`Classical.choice`, `Quot.sound`) or the tolerated `sorryAx`; any other axiom
+declines. The **axiom policy** (`AxiomPolicy`) is the one parameter that
+tells this fold apart from the fold that also admits *user axioms*:
+
+* `strict` is `checkDecls` itself (`checkDeclsUnder_strict`);
+* `allowUser` also admits an `.axiomDecl` under an eligible key
+  (`Key.isCustomAxiomEligible`: an input key that names no role), with its
+  header and type checked and installed as `.axiomInfo`, unless its type
+  restates an axiom role's pinned specification (`axiomRoleSpecHit?`): that
+  is a role's own axiom read under an input key because the role table does
+  not bind the role, and it declines.
+
+An accept under `allowUser` is conditional on the user axioms of its records,
+`userAxiomsOfDecls` (`IxC/Kernel/Roles.lean`), which are read off the
+declarations, not the environment: the fold installs an opaque as
+`.axiomInfo` too. The main theorem's model (`Ix.Kernel.model_exists`) is the
+strict fold's; under `allowUser` this module proves that **without user
+axioms the two folds are the same function**
+(`checkDeclsUnder_eq_checkDecls`), so an accept that admitted none carries
+every theorem of the strict fold (`IxC/Kernel/Verify/Cached/PolicyC.lean`
+proves the converse and `MainC`/`MainTheorem` the soundness letters).
+
+The policy enters at exactly one place, the axiom arm (`checkAxiomDeclC`).
+Everything else of a step is the strict fold's: `annotStepUnderC` overrides
+`annotStepC` at `.axiomDecl` only, and `annotDeclStepUnder` and
+`checkDeclsUnder` are `annotDeclStep` and `checkDecls` over it. The strict
+definitions keep their own bodies, which the frozen runtime closures and the
+proof towers read; that `strict` is them is proved here
+(`checkDeclC_axiomDecl`, `annotStepUnderC_strict`, `annotDeclStepUnder_strict`,
+`checkDeclsUnder_strict`), so the two can never drift apart. Like the fold's
+own lemmas these use nothing but the definitions, so they live beside them.

+# The strict fold is the user-axiom fold without user axioms
+
+`IxC/Kernel/Cached/Policy.lean` proves that, over records none of which is a
+user axiom, the fold under any axiom policy is the certified fold `checkDecls`
+(`checkDeclsUnder_eq_checkDecls`). This module proves the converse: the
+certified fold accepts no user axiom, because its axiom arm admits only
+role-keyed axioms (`checkStdAxiomDeclC_eligible`). Together,
+`checkDecls_iff_userAxioms`: the certified fold accepts exactly what the fold
+that admits user axioms accepts without any. So a host may run the
+user-axiom fold alone: an accept whose user axioms are none is the certified
+fold's accept, and nothing the certified fold accepts is lost.

-1. Get Lean.Environment
-2. Canonicalize via Rust FFI → Ix.Environment
-3. Compare Rust Ix.Environment against original env (iterate env.constants)
-4. Canonicalize via Lean → Ix.Environment
-5. Compare Lean Ix.Environment against Rust (should be identical)
-6. Uncanonicalize back to Lean.Environment
-7. Compare roundtripped environment to original (iterate env.constants)

-  auxiliary-closure: Lean's auxiliaries and mutual definitions on
-  closure-only environments.
-
-  A raw dependency closure (`Ix.EnvScope.collectDeps`, which any claim
-  built from a dependency closure may use) hands the compiler only the
-  seeds' transitive dependencies. The cases below keep the raw collector on
-  purpose: the selected closure (`collectSelectedDeps`: recursors, whole
-  logical units, checker support) is a superset and would hide the partial
-  families tested here. Such a closure can hold a nested auxiliary
-  `<all0>.brecOn_N`/`.below_N`, or one member's `.brecOn`, without the
-  `.brecOn`/`.below` of the block's first member, and a Prop inductive's
-  auxiliaries nested through a Prop inductive. Each case compiles exactly
-  that closure (`ix compile`'s path, fail-closed) and type-checks the seed
-  with the Rust kernel (`rsCheckConstsFFI`: Lean closure → Ixon compile →
-  kernel), and expects both to pass.
-
-  A second case, `mutual` definitions on closure-only environments: a
-  structural, well-founded or `partial` `mutual` member's value goes
-  through auxiliaries and never mentions its siblings, but its compiled
-  metadata carries Lean's `all` (the siblings' names), which meta kernel
-  ingress resolves through the env's Named entries. `collectDeps` follows a
-  definition's `all`, so the closure of `oddN` (or of a theorem about it)
-  holds `evenN`, and `ix check-rs` accepts the written `.ixe` (before,
-  `resolve_all: Named entry for 'evenN' missing`). That case compiles the
-  closure to a file, as `ix compile` does, and checks the file with the
-  meta Rust kernel, as `ix check-rs` does.
-
-  Run with: `lake test -- --ignored auxiliary-closure`.

@@ -15,35 +25,52 @@
 
   For each fixture constant (the seed) this compiles the seed's closure and
   checks, for every name the closure output shares with the reference
-  compile (the closure of all fixtures, where every family is complete),
-  that the address is the reference's; and type-checks the seed with the
-  Rust kernel. Two legs:
+  compile, that the address is the reference's. The reference is the
+  selected closure of all fixtures (`collectSelectedDeps`, where every
+  family is complete), compiled and bound as `ix compile --consts` compiles
+  and binds it (`Ix.RoleBinding.Compile.finalize`). Four legs:
 
   - `collectDeps`: the raw closure producers' closure, which pulls an
     auxiliary's whole family (`Lean.auxFamilySiblings`) and a definition's
-    `all`. Every address must match. (`ix compile --consts` now takes the
-    selected closure, `collectSelectedDeps`, a superset with recursors,
-    whole logical units and checker support; this leg keeps the
-    raw collector, which reaches fewer family members.)
+    `all`. Every address must match.
   - `raw`: the closure without family completion (`rawDeps`), which tests
     the compiler's per-family block membership on its own. Every address
     must match: the compiler compiles Lean's auxiliaries as Lean declared
     them, so a family-incomplete slice (a nested block's class
     `.brecOn.eq`, whose family holds `<all0>.brecOn_N.eq`) compiles to the
     whole compile's addresses.
-  - `pack`: `ix pack` (`rsPackEnv`) of the reference to each auxiliary
-    seed keeps the seed's address and type-checks (`rsCheckIxonFFI`).
+  - `selected`: the selected closure (`collectSelectedDeps`, what
+    `ix compile --consts` takes: recursors, whole logical units, checker
+    and literal support). Every address must match, and the certified
+    checker (IxC, `rsCheckIxonFFI`) accepts or types the seed in that
+    artifact.
+  - `pack`: `ix pack` (`rsPackEnv`) of the bound reference to each
+    auxiliary seed keeps the seed's address, and IxC accepts or types the
+    seed in the bundle.
+
+  And `twin` (`twinRecursorCheck`): a closure that is not closed over its
+  recursors can meet the compile's recursor check on alpha-equivalent
+  families, which refuses it whole; closed over them it compiles.
+
+  Only the `selected` and `pack` artifacts are type-checked. IxC reads an
+  inductive block together with its recursor and declines it otherwise
+  (`reader: inductive block without a recursor in the input`,
+  `Ix.EnvScope.ClosureOptions.recursors`), and neither the `collectDeps`
+  nor the `raw` closure carries the recursors of the library families it
+  reaches (`PProd`, `Nat`, …). The selected closure of either leg's closure
+  is the seed's own selected closure (`collectSelectedDeps` is a fixed
+  point, and each leg's closure lies inside the seed's), so the `selected`
+  leg checks the seed in exactly the closure that makes either leg's input
+  self-contained. Likewise `ix pack` carries the recursors of the
+  inductives a bundle reaches only for a bound artifact
+  (`crates/ixon/src/binding_support.rs`), so the reference is bound. On
+  `main` these checks ran the Rust kernel, which needed neither.

-  compile-claim-conflict: single ownership of compiled names, in both
-  compilers (a name assigned twice is an error unless both assignments are
-  equal).
-
-  Rust's scheduler claims names insert-once (`CompileState::claim_compiled_name`)
-  and raises
-  `conflicting claims for name '…': already registered at …, claimed again at …`
-  on a second claim at another address. The Lean drivers check the same claims
-  at merge time (`Ix.CompileM.checkBlockClaims`). Two parts:
-
-  1. **Driver API.** The insert-once merge is driven directly: through
-     `checkBlockClaims` then `mergeCompiledBlock` (what every driver does
-     with a compiled block) and through `applyAuxBlockOutcome` (the wave
-     driver's merge, with two blocks of one wave claiming one name): a second
-     compiled claim at another address is refused with Rust's message,
-     character for character, and an identical re-claim is accepted. An
-     identical re-claim of a name an earlier block owns keeps the owner's
-     `Named` entry, while a block's own second registration of a name
-     replaces its first. A source dependency is ready only when its own block
-     has settled (`auxDependencyReady`).
-  2. **Both compilers.** A constructed closure holds a user constant named
-     `T.below` (a plain definition, not Lean's auxiliary) for a recursive
-     inductive `T` whose field type depends on it, so `T.below` compiles
-     before `T` in every schedule. Real Lean input cannot contain this:
-     Lean's own `mkBelow` would have failed on the name. Both compilers
-     compile Lean's declarations as given, so `T`'s block claims only its
-     own names and nothing claims the user's `T.below` a second time: the
-     Rust compiler (`ix compile`'s FFI), the fold, the reference schedule
-     (least and greatest key first) and the `ix compile-lean` pipeline (1, 4,
-     16 workers) must all compile the whole closure, with no refusal.
-
-  Run with: `lake test -- --ignored compile-claim-conflict`.

-  compile-schedule-identity: compare the pure fold and streamed Lean
-  pipeline under different schedules on the same fixture corpus.
-
-  Over the fixture corpus (`validateAuxClosure`: `Tests.Ix.Compile.Mutual`,
-  `Canonicity`, `LevelSpellings`, the IxVM and `Test.Ix.Fixtures`
-  families), compile with
-
-  - the driver, the pure wave fold `Ix.CompileM.compileEnvFold`, on the
-    canonical environment and condensation of `rsCompilePhasesOf`,
-    at its default width and at widths 1 and
-    32 (tasks per wave; the value must not depend on it);
-  - the reference schedule (`Tests.Ix.Compile.ScheduleReference.sequential`,
-    a sequential driver: live state, one block at a
-    time) on the same input,
-    with the least and with the greatest ready key first;
-  - the streamed `compileLeanInput` pipeline through
-    `ClosureHarness.compileClosure`, with its own canonicalization and
-    condensation, at 1, 4 and 16 workers;
-
-  and require every serialized environment and decline report to be identical. A
-  difference is reported with the constant and its two addresses.
-  These comparisons cover raw compiler artifacts before CLI finalization.
-
-  Failures: no block fails under any schedule, and every source name is in
-  the output.
-
-  The legs run concurrently (each is an independent compile of the same
-  read-only input; `SCHED_JOBS=<n>` runs at most n at a time), and are
-  reported and compared in the order above once all have finished.
-
-  Tiers: the default (`SCHED_LEGS=full`) is the integration gate, all eight
-  legs. `SCHED_LEGS=quick` is the per-iteration tier: `fold` (the
-  reference), `reference, least key first` and the streamed pipeline at 16 workers,
-  with every check below; it is never the integration gate.
-  `SCHED_OUTPUT_DIR=<dir>` writes each leg's bytes and failures, for
-  diagnosis.
-
-  Run with: `lake exe IxTests --ignored compile-schedule-identity`.

-  A second schedule of the Lean compiler, for the tests only: a sequential

+  Cross-process compile determinism.
 
-  Every existing determinism gate runs both compiles in ONE process
-  (memory/parallelism modes over a shared frontend env). The piece
-  cache of the `.ixc` catalog trusts more: two `ix compile` runs of
-  the same member, in separate processes on possibly different days,
-  must produce `sha256`-identical `.ixe` files — the file hash in the
-  catalog manifest is the cache key's witness. The root alone is not
-  enough: `status.root` commits only §2, while the file also carries
-  blobs, hints, and names.
-
-  Two legs, both driving the real CLI binary in fresh subprocesses:
-
-  * fixture-class: `Tests/Ix/Compile/Mutual.lean` — the mutual
-    fixture corpus, module-visible closure, seconds.
-  * Batteries-class: `Benchmarks/Compile/CompileBatteries.lean` — a
-    real library through the sub-workspace bootstrap path
-    (`buildFile` + oleans), minutes.
-
-  `IxTests` depends on the `ix` executable target, so the ignored suite
-  (`lake test -- --ignored compile-determinism`) is self-contained. The
-  Batteries leg needs network on the first workspace build.
+  Two `ix compile` runs of the same module in separate subprocesses must
+  produce Blake3-identical `.ixe` files — committing not only the canonical
+  constants (`status.root`), but also blobs, hints, and names.
+  (Large-corpus cross-process byte determinism against a pinned reference
+  digest is also gated by `initstd-reference` in `ci:landing-initstd-cli`.)

-Unit tests for `Ix.Ground` (the pure-Lean port of
-`crates/compile/src/ground.rs`).
-
-Coverage mirrors the Rust `#[cfg(test)]` module in ground.rs (grounded
-constants, missing refs, out-of-scope bvars, mvars, level params,
-inductive ctor checks, depth increments, fvars, propagation) plus
-Lean-side checks of the exact traversal/cache semantics: the
-`(binder-depth, expr)` cache key, sub-check ordering (ctors before
-type, rec rules before type, const levels before env lookup, proj env
-lookup before struct), and worklist termination on cyclic in-ref
-graphs.
-
-Per the contract documented on `Ix.proliferateUngrounded`, everything
-transitive is asserted by error KIND only (`GroundError.kind`) — never
-by transitive `.ref` attribution payloads, which are pop-order
-dependent. Immediate-error payloads (which ARE order-independent) are
-asserted where the Rust tests assert them.

-The generator-driven properties (`Tests.Ixon.suite`) cover the wire grammar
-compositionally; this suite covers whatever hand-written generators miss,

-ENTIRE current Lean environment — every block kind, its metadata, and every

-Gate:
-1. Rust-compile the whole `get_env!` to `.ixe` bytes.
-2. The pure-Lean parser (`Ixon.deEnv`) must parse them — every metadata
-   variant, no lossy skips.
-3. The pure-Lean writer (`Ixon.serEnv`) must reproduce the input bytes
-   EXACTLY (writers are canonical: section sort orders, name topological
-   order, index assignment, and metadata encoding all agree).
-4. The Rust FFI value path (`Ixon.rsDeEnv`) must agree with the pure parse
-   (content comparison per section).

-  Dump ORIGINAL (LEON content-hash) primitive addresses for hardcoding
-  into the Rust kernel (`crates/common/src/prim_addrs.rs::PrimAddrs::new_orig`).
-
-  Run with: `lake test -- --ignored rust-kernel-build-prim-origs`. The test prints a
-  `(lean_name, leon_hash_hex)` line for every primitive the Rust kernel
-  expects to find in `PrimAddrs::new_orig`. Each hex is
-  `ConstantInfo::get_hash()` (defined in `src/ix/env.rs`) on the
-  primitive's declaration in the current Lean environment — a Blake3
-  digest over the serialized original `ConstantInfo` (name + level
-  params + type expression + variant-specific fields: ctors, rules,
-  `all`, value, hints, etc.).
-
-  This is the addressing scheme `orig_kenv` uses: two Lean constants
-  with the same name but different content hash to different addresses,
-  so a rogue environment can't silently shadow a primitive just by
-  naming its own declaration `Nat`.
-
-  Paste the output lines into `PrimAddrs::new_orig` whenever either:
-  - a primitive's Lean-side name or content changes upstream, or
-  - the `ConstantInfo::get_hash` byte layout is revised.
-
-  The primitive name list itself is shared with
-  `Tests.Ix.Kernel.BuildPrimitives.kernelPrimitives` — a single source
-  of truth. When upstream Lean renames a primitive, update that list
-  once and regenerate BOTH this table AND the canonical one (via
-  `rust-kernel-build-primitives`).
-
-  Failure modes:
-  - Missing: a primitive name isn't in the Lean env (likely renamed
-    upstream). Printed as `// MISSING:` comments so the emitted table is
-    still valid as-is for partial regeneration.
-  - Address change: the LEON hex for a primitive has changed — paste
-    the new hex into `PrimAddrs::new_orig`.

-/-! # The kernel's level comparison against brute-force evaluation
-
-`Ix.Kernel.Level.leq` is nanoda's comparison with Géran's sublevels as the
-fallback of its `(param, max)` case (`IxC/Kernel/Level.lean`,
-`IxC/Kernel/LevelGeran.lean`). `leqCore_sound` proves a `true` verdict
-pointwise; `Geran.leq_iff` proves the fallback a decision. This host-only
-gate checks that the whole comparison is complete in practice too. For every
-pair below it compares `Level.leq`, `Level.isEquiv` and `Level.Geran.leq`
-(at offsets `-2‥2`) with evaluation (`Level.eval`) at every valuation of the
-parameters in a range:
-
-* exhaustively: every level of up to five constructors over two parameters
-  and of up to four over three, at values `0‥M`, where `M` is four above the
-  pair's largest `succ` nesting;
-* on 100,000 random pairs of up to sixteen constructors over three
-  parameters, with each pair's `max` commuted and an `imax` absorbed (so
-  that true equalities are frequent), at values `{0, 1, 2, M - 1, M}`;
-* on 20,000 random levels of up to twelve constructors over three
-  parameters, biased towards `imax` by a parameter (the shape of canonical
-  forms), against the same level rewritten by laws of the semantics
-  (equal by construction), at the same values;
-* on 20,000 such levels through Ixon's canonical form (`Ix/IxonUniv.lean`,
-  the form the reader hands the checker): a level against its canonical
-  form, and the canonical form of a `max`, `imax` or `succ` against the
-  constructor over canonical forms, as type inference builds them
-  (`RatFunc.liftOn_def` is `max (canon W) 1` against `canon (max 1 W)`).
-  These pairs are not all equalities: `canonUniv` changes the value of some
-  levels (the smallest found is `imax (imax (imax u w + 1) u) v`, whose
-  canonical form is `2` at `u = 0, v = 1, w = 2` where the level is `1`),
-  counted, not failures;
-* on the recorded witnesses: Ixon's canonical levels of `RatFunc.liftOn_def`
-  and the equality Ix.Tc's subsumption misses.
-
-Some valuation at values in `{0, 1, M}` is a counterexample whenever one
-exists, at offsets up to `2` (the separating valuations of
-`Geran.dominated_of_le` work with any `N` above the other side's
-`valueBound`), so the oracle is exact. A `true` verdict that some valuation
-refutes is unsound; a `false` verdict that no valuation refutes is
-incomplete; a `none` is an internal error. Each is a failure. Output is one
-summary line; the exit code is nonzero on any failure. -/

-  This test closes that class. It reads the byte arrays out of the
-  ELABORATED toplevel — not the source text — and compares each against
-  the address computed at test runtime from `Ix.PrimAddrs`, which is
-  the same table the host-side closure walker and ingress verifier use.
-  Any drift between the two sources of truth fails here.
-
-  Coverage is by construction: every `fn <name>() -> Addr` in the
-  toplevel whose body is a 32-byte literal must resolve to a canonical
-  address, and the test reports the count so a silent drop to zero
-  (e.g. an AST shape change) cannot pass unnoticed.
+  Guards the IxVM's address literals.
+
+  The IxVM kernel once hardcoded ~77 primitive constant addresses as
+  32-byte literals (`fn nat_add_addr() -> Addr { store([0xd6u8, ...]) }`)
+  so reduction could recognize `Nat.add` etc. by address alone. A single
+  wrong byte was a soundness-relevant defect, invisible to the FFT-pinned
+  suite and the arena fixtures; one shipped for months (`bool_false_addr`,
+  last 8 bytes wrong). Every constant a native rule recognizes or builds
+  is now a role, read through the claim's role binding and validated
+  against its specification, so the only literal left is the
+  specification digest.
+
+  This test keeps it that way. It reads the byte arrays out of the
+  ELABORATED toplevel — not the source text — and requires the
+  specification digest, equal to `Ix.SpecDigest.specDigest`, to be the
+  only one: an address literal reappearing fails, and so does the
+  extractor finding nothing (e.g. an AST shape change). A literal that
+  did reappear must also resolve to the canonical address its name
+  claims, computed at test runtime from `Ix.PrimAddrs`.

+under each axiom policy (`Ix.Kernel.Cached.AxiomPolicy`,
+`IxC/Kernel/Cached/Policy.lean`), and the role table's admission under the
+policy (`Ix.Kernel.Admission.admitAxiomPolicy`):
+
+* a user axiom (`axiom cheat : False`) declines under `strict` and is admitted
+  under `allowUser`, which lists it, and a theorem proved from it is accepted
+  only there;
+* Lean's own `sorryAx`, read under an input key because the table leaves the
+  role unbound, declines under both, and so does a restated `Quot.sound`: the
+  user arm refuses an axiom whose type is an axiom role's specification;
+* without user axioms the two folds agree (T1), on the prelude and with an
+  ordinary axiom-free declaration added;
+* a check that admits user axioms refuses a table that leaves `sorryAx`,
+  `propext` or `Classical.choice` unbound, as an admission error, before
+  reading; the strict check does not ask. -/

-  Lean/Rust differential test of the exact sharing constructions.
-
-  Every check normalizes one Constant twice: in Lean (`normalizeConstantSharing`,
-  `normalizeConstantSharingUniform`, `normalizeConstantSharingTiered` from
-  `Ix.Sharing.Exact`) and in Rust through the `test-ffi` hooks
-  `rs_exact_sharing_normalize`, `rs_uniform_sharing_normalize` and
-  `rs_tiered_sharing_normalize` (crate `ixon::sharing_exact`). The two sides
-  agree when both succeed with the same serialized bytes, or both fail with
-  the same error category (malformed / format / resource / internal). One
-  side exhausting a resource limit while the other succeeds is reported
-  separately: the two implementations count work differently, and limits
-  may change success but never the bytes of a success. These groups are
-  strict: every comparison must be a byte-identical success (the exact
-  search runs only on inputs with few candidates).
-
-  The inputs of these groups: the §2 fixtures, 350 inputs of the generated
-  families of the uniform and tiered tests, the tiered outputs of the
-  fixtures and of generated inputs re-normalized from their stored tables,
-  the scale inputs of the tiered tests (a table past the 3-byte TagN rung, a
-  1288-argument spine, 10000-deep inputs; uniform and tiered modes), and
-  doubling towers whose unshared lengths exceed `2^127` (tiered mode).
-  Malformed stored tables (forward, self and out-of-range references) must
-  be rejected as malformed by both sides, with the expected Lean error.
-
-  A codec group checks the TagN Share codec: Lean and Rust serialize
-  Share-bearing Constants (tiered TagN outputs and synthetic tables up to
-  66,600 entries) to the same bytes (`rs_eq_constant_serialization`).
-
-  A compiler-route group checks the fourth hook, `rs_compiler_sharing_build`
-  (Rust `apply_sharing_to_*_with_limits`, crate `ix_compile`): it and Lean
-  `Ix.CompileM.buildConstantWithSharing` build the same bytes from the same
-  unshared Constant, equal to the tiered normalizer's.
-
-  Modes: `tiered-tagN` is the canonical construction (the compiler's);
-  `uniform-w<k>` is its phase-1 optimizer alone at Share width `k`; `exact`
-  is the width-state search for the global minimum, a test oracle for small
-  inputs (not the compiler path).
-
-  Corpus mode: when `IX_SHARING_CORPUS` names an `.ixe` file, every constant
-  of that corpus (expanded from its stored table) is compared in the modes
-  listed in `IX_SHARING_CORPUS_MODES` (comma separated, default
-  `tiered-tagN`; also `uniform-w<k>`, `exact`), only the constants whose
-  addresses are listed in the file `IX_SHARING_CORPUS_SELECT` when that is
-  set, and stops after `IX_SHARING_CORPUS_LIMIT` constants when that is set.
-  No CI job sets `IX_SHARING_CORPUS`.

-//! The benchmark row contract shared by every measured tool.
-//!
-//! Each tool (`bench-typecheck`, `ix check-rs`,
-//! `ix compile`) reports its results as one JSON object per benchmark name in
-//! a single file:
-//!
-//! ```json
-//! { "<name>": { "status": "ok", "<metric>": <number>, ...,
-//!               "phase:<span>": <seconds>, ... } }
-//! ```
-//!
-//! Rows are flushed to disk after every name, so a killed process still
-//! leaves a complete file of the rows measured so far. The orchestrator
-//! (`ix bench run`) identifies a killed run's in-flight name as the first
-//! requested name without a row, and merges `"status": "oom"` into whatever
-//! partial metrics that row holds — tools themselves only ever write `ok` or
-//! `rejected`.
-//!
-//! Exit codes are the failure channel (no stdout markers, no log grepping):
-//! `0` — every row `ok`; [`EXIT_USAGE`] — bad invocation; [`EXIT_REJECTED`] —
-//! the kernel rejected a constant (its `rejected` row is on disk; the tool
-//! fails fast, so later names have no rows). Any other exit is an

-//! Lean's block-wide inductive flags (`isRec`, `isReflexive`, `numNested`),
-//! recomputed from the constructors.
-//!
-//! Ixon does not store these flags, so kernel egress and decompilation
-//! reconstruct them, and compilation rejects an environment whose stored
-//! flags differ from the recomputed ones (a domain restriction).
-//!
-//! `numNested` counts the auxiliary members of the block's nested expansion:
-//! every nested occurrence in constructor syntax (e.g. the `List Tree` inside
-//! `Id (List Tree)`) is replaced by an auxiliary member sharing the block's
-//! parameters and levels, as the C++ kernel's `elim_nested_inductive` does.
-//! The traversal walks syntax without delta-reducing definition heads.
-//! Block parameters are opened as FVars; later binders retain BVars. Free
-//! BVars and non-parameter FVars cannot enter a specialization.

-// This is the inverse of `ixon_ingress`. We walk each constant in the kernel
-// env, produce the corresponding Ixon `Constant` payload, and pair it with
-// the original `ConstantMeta` (arena + extension tables) so the output env
-// is a well-formed input for `decompile_env`.
-//
-// Why we reuse the original meta: the kernel does not track per-expression
-// metadata like binder names, mdata KV-maps, or call-site surgery — those
-// live in `ConstantMeta.arena` + `meta_sharing` / `meta_refs` / `meta_univs`.
-// Regenerating them from kenv alone would be equivalent to re-running
-// compile's call-site surgery pass (hundreds of LOC, and any divergence
-// would reintroduce the "second decompiler" problem we're trying to solve).
-// Instead we take the original `Named.meta` as-is.
-//
-// Consequence: `ixon_egress` is only meaningful after a prior `compile_env`
-// produced the original `IxonEnv`. For the diagnostic roundtrip test that's
-// fine — the test path is `compile_env → ixon_ingress → kenv → ixon_egress
-// → decompile_env`. Callers without a pre-existing compile state would need
-// to regenerate metadata themselves (out of scope here).
-//
-// Meta-only: we only need this for the Meta-mode roundtrip diagnostic.
-// Generalizing to `<M: KernelMode>` requires address-keyed lookups (in
-// Anon mode `kid.name` is `()`, so we can't look up `original_env.named`
-// by name). Left as future work.

-//! Pipeline:
-//!
-//! 1. Decode the Lean environment into the Rust `Env` type.
-//! 2. Run `compile_env` to obtain the Ixon environment.
-//! 3. Run `ixon_ingress::<Meta>` to ingress into the kernel.
-//! 4. For each requested name, construct a `TypeChecker` sharing the
-//!    `Arc<KEnv>` (so whnf / infer / def_eq caches accumulate across the
-//!    batch) and call `check_const`.
-//! 5. Return a Lean `Array (Option CheckError)` reporting per-name
-//!    results, where `some (.kernelException msg)` signals a rejection.
-//!
-//! The `CheckError` ABI (tag 0 = `kernelException`, tag 1 = `compileError`)

-//! The roundtrip helpers below `rs_kernel_check_consts` are test-only

-/// side rejections from kernel-side rejections at the Lean call site, and
-/// (2) to prevent Lean's LCNF "trivial structure" optimization from
-/// elididing a single-ctor-single-field inductive into its field type
-/// (`hasTrivialStructure?` in `Lean/Compiler/LCNF/MonoTypes.lean`). Without
-/// that, the runtime representation of `CheckError` would be identical to

-/// line, matching the format `readNamesFile` understands) as it is detected,
-/// and flushes after every record so the file is immediately readable from
-/// outside the process.
-///
-/// Records are written under a `Mutex<File>` so parallel workers don't
-/// interleave bytes — failures are rare enough that the lock contention is
-/// negligible, and `File` writes go straight to the kernel page cache so

-/// with the Lean side round-tripping names through `Name.toString` (which
-/// adds `«»` escaping for non-identifier components) and Rust reparsing
-/// them back into a `Name`. That round-trip was brittle: Lean's escaped
-/// `Lean.Order.«term_⊑_»` didn't match the kernel's unescaped
-/// `Lean.Order.term_⊑_` key and logged `? not found`. Structural pass-
-/// through via `decode_name_array` is the canonical form.
-///
-/// `expect_pass[i]` is a hint: `true` means "good" (checker expected to
-/// accept), `false` means "bad" (checker expected to reject). It only
-/// influences per-constant progress logging; the actual pass/fail logic
-/// lives on the Lean side.
-///
-/// `quiet` toggles the progress-output style:
-/// - `false` (verbose): every constant is printed with its elapsed time,
-///   matching the original line-per-constant behaviour.
-/// - `true` (ephemeral): the current `[i/N] name ...` label is written
-///   over itself each iteration, and *only* slow constants (>=7s by default),
-///   unexpected passes/failures, not-found names, and ungrounded compile
-///   failures are promoted to persistent lines. Suitable for full-env
-///   runs where the vast majority of constants are expected to pass
-///   quickly.
-///
-/// Parallel quiet-mode progress is persistent and compiler-like: periodic
-/// `done/total`, rate, ETA, and oldest in-flight constants. Useful knobs:
-/// `IX_KERNEL_CHECK_PROGRESS_MS`, `IX_KERNEL_CHECK_SLOW_MS`,
-/// `IX_KERNEL_CHECK_ACTIVE_SLOW_MS`, `IX_KERNEL_CHECK_INFLIGHT`, and
-/// `IX_KERNEL_CHECK_NAME_CHARS`.

-/// FFI: anon-mode type-check of named constants with (by default) their full

-/// work item (subject-only; deps trusted). Every mode also checks the
-/// closure of a bound artifact's role records and certificates, which role
-/// admission assumes and a verdict on an admitted role rests on.
-///
-/// Names resolve through the env's `named` metadata by displayed form,
-/// then the metadata is dropped and
-/// the check runs on the anon view — the kernel never sees names. A member
-/// of a mutual block selects the whole block's work item (blocks check
-/// atomically). Multiple names union their closures into one check set.
-///
-/// `json_path` (empty = off) additionally emits per-name benchmark results
-/// rows. With it set, each name is checked as its own closure run — the
-/// per-constant scope the zkVM hosts measure — instead of one union set:
-/// the env still loads once, and each row's `check-time`/`peak-rss` window
-/// wraps only that name's closure selection + check. Rows are flushed per
-/// name, so a killed run keeps completed rows; a rejected name gets
-/// `status: rejected` and the loop continues.
-///
-/// Returns `(hex_address, Option CheckError)` pairs, one per checked target,
-/// exactly like `rs_kernel_check_anon` (concatenated across names when
-/// per-name rows are on — shared deps then appear once per name that

-//! Encode Rust `ix_common::env` values as real Lean kernel objects.
-//!
-//! The reverse of `lean_env.rs`: where that module decodes Lean's in-memory
-//! C representation into the Rust `Name` / `Level` / `Expr` / `ConstantInfo`
-//! types, this one constructs genuine `Lean.Name` / `Lean.Level` /
-//! `Lean.Expr` / `Lean.ConstantInfo` objects from those Rust values, for
-//! FFI entries that hand decompiled constants back to Lean (the
-//! materialization path behind `import_ixe`).
-//!
-//! `Name`, `Level`, and `Expr` carry `@[computed_field]` data words (hash,
-//! loose-bvar depth, has-fvar flags, …) that MUST be computed by Lean's own
-//! algorithms, so those three types are built exclusively through the
-//! toolchain's exported constructors (`lean_name_mk_*`, `lean_level_mk_*`,
-//! `lean_expr_mk_*` — the `mk*Ex` exports in `Lean/Expr.lean` and
-//! `Lean/Level.lean`). Plain structures (`Literal`, the `*Val` payloads,
-//! `ConstantInfo` itself, `Syntax`, …) have no computed fields and are
-//! allocated directly through the `LeanIx*` layout types, whose field
-//! orders are pinned by `lean_env.rs::decode_constant_info`.
-//!
-//! Sharing: `ExprData` / `LevelData` / `NameData` live behind `Arc`s that
-//! the decompiler dedups aggressively; the encode cache keys on those Arc
-//! data pointers so shared Rust subterms become shared Lean objects. One
-//! cache should span a whole marshaling batch (sharing crosses constant
-//! boundaries).
-//!
-//! Expression encoding is iterative (explicit frame stack): Init-scale
-//! terms overflow default runtime stacks (same reason
-//! `Ix/Tc/EgressLean.lean` uses a stack machine).
-//!
-//! Known hole, deliberate: `DataValue::OfInt` inside mdata is rejected
-//! with an error. Lean's runtime `Int` is scalar-or-mpz (no exported
-//! constructor symbol), and the decode direction's ctor-read of an `Int`
-//! would have crashed on any real env carrying one — empirically the case
-//! never occurs in kernel constants.

-//! Decode Lean kernel objects from their in-memory C representation.
-//!
-//! Provides functions to walk Lean object pointers and decode them into
-//! the Rust `Name`, `Level`, `Expr`, and `ConstantInfo` types defined in
-//! `ix_common::env`. Used by the compilation pipeline to read the Lean
-//! environment before transforming it to Ixon format.
-//!
-//! Uses a two-level cache (`GlobalCache` + `LocalCache`) to avoid redundant
-//! decoding of shared subterms when processing environments in parallel.

-//! Universe-level canonicalization (canonicity §10.6).
-//!
-//! `canon_univ = linearize ∘ subsumption ∘ normalize_aux` — a total,
-//! deterministic canonical representative of a stored level's Géran
-//! semantic-equality class, kernel-free and next to the wire type so the
-//! compilers, the Tc egress, and probes can all use it (the three kernel
-//! `NormLevel` implementations stay untouched and serve as the P4
-//! oracle). Mirrors `Ix/IxonUniv.lean`; the Géran machinery is the
-//! transliteration of `Ix/Tc/Level.lean:227-472` /
-//! `crates/kernel/src/level.rs` onto `ixon::univ::Univ`.
-//!
-//! The frozen kernel `mk*` rule set (M1–M8 / I1–I6, from Lean's
-//! `kernel/level.cpp:81-120` via the three kernel mirrors) is kept with
-//! its kernel-rebuild role: [`reduce_univ`] is the stage-1
-//! decoration-presence test and the P6 oracle, and P3 (canonical forms
-//! are `mk*` fixpoints) is what makes kernel ingress the identity on
-//! canonical content.
-//!
-//! Property set (tested here; Verify-layer proofs are the D7 follow-up):
-//! - P0 value preservation: `canon_univ u` and `u` agree at every
-//!   valuation of the params (the compiler must not change the universe
-//!   a declaration states);
-//! - P1 idempotence: `canon_univ (canon_univ u) = canon_univ u`;
-//! - P2 roundtrip-fixpoint: `normalize (linearize L) = L` for reachable
-//!   `L` — exact on non-empty entries; `subsumption` can leave EMPTY
-//!   entries behind (constant 0, no vars) which `linearize` cannot (and
-//!   should not) re-express, so the strict form holds modulo empty
-//!   entries ([`norm_eq_semantic`]). See the O1 note below.
-//! - P3 mk*-fixpoint: `reduce_univ (canon_univ u) = canon_univ u`;
-//! - P4 soundness: `univEq u (canon_univ u)` against the kernel oracle
-//!   (lives in the kernel/Tc test suites — this crate cannot depend on
-//!   the kernels), modulo the same empty-entry caveat;
-//! - P5 mirror parity: byte-for-byte agreement with `Ix/IxonUniv.lean`
-//!   (FFI cross-check in the Lean test suite);
-//! - P6 mk* absorption: `canon_univ (reduce_univ u) = canon_univ u`.
-//!
-//! O1 empty-entry note: kernel `normLevelEq` compares subsumption output
-//! maps INCLUDING empty entries, which makes kernel `univEq` strictly
-//! finer than semantic level equality on rare shapes (34 of 3,253,373
-//! whole-Mathlib table entries — e.g. `succ (max (u+1) (imax (u+1) v))`
-//! keeps an empty `[u,v]` entry that its semantic equal
-//! `max (u+2) (v+1)` never creates). `canon_univ` canonicalizes BY
-//! SEMANTIC CLASS (empties carry no value), which is the "all the way to
-//! Géran" endpoint; aligning the kernels' `normLevelEq` to ignore empty
-//! entries (a completeness improvement — `normLevelLe` already ignores
-//! them) is the pending kernel-side counterpart decision.

-//! Sharding: partition an environment's blocks into shards that minimize
-//! cross-shard delta-unfold ingress (see `plans/sharding.md`). Two driving
-//! modes share the same min-cut machinery:
-//!
-//! - **Fixed count** ([`Hypergraph::partition`], explicit `--shards N` and the
-//!   static strategy's `--max-ram` score seed): recursive *balanced* min-cut
-//!   bisection into exactly `N` shards — even per-shard work, the bisection tree
-//!   doubling as the aggregation tree.
-//! - **Cap / packing** ([`partition_for_cycle_cap`], the profiled strategy's
-//!   default and `--max-cycles`/`--max-ram` paths): **bin-pack to the cap** — the
-//!   fewest shards that each stay under a per-shard cycle (hence prover-RAM)
-//!   budget, each filled as full as the dependency structure allows. This does
-//!   *not* balance: uniformity over-shards (every shard left partly empty),
-//!   whereas packing hits `≈⌈total/cap⌉` shards. It still uses a fine min-cut
-//!   pre-partition for a **cut-coherent order** so dependency overlap packs into
-//!   the same shard (overlap paid once, not re-ingressed per shard).
-//!
-//! Min-cut keeps dependency-overlapping blocks together, reducing repeated
-//! ingress and bounding each shard's injected closure. The cap planner
-//! ([`partition_for_cycle_cap`]) is order-agnostic, so the ordering remains a
-//! pluggable choice.
-//!
-//! ## Model
-//!
-//! Both modes view the env as a **weighted hypergraph** under the
-//! connectivity-1 (km1) metric:
-//!
-//! - **Vertices** are blocks, weighted by `heartbeats` (the balance metric).
-//! - **Nets** are blocks `p` that get delta-unfolded by someone; the net
-//!   connects `p`'s home plus every block that unfolds `p`, and is weighted by
-//!   `serialized_size(p)` (the ingress cost paid to pull `p`'s body into a
-//!   foreign shard).
-//! - The objective is `Σ_p  size(p) · (λ(p) − 1)`, where `λ(p)` is the number
-//!   of distinct shards spanning `net(p)`. Because the home block is always a
-//!   pin, `λ(p) − 1` counts exactly the foreign shards that must ingress `p` —
-//!   i.e. total cross-shard ingress bytes.
-//!
-//! ## Algorithm
-//!
-//! **Recursive bisection.** Balanced min-cut bisection recursively splits the
-//! block hypergraph, allocating the `N`-shard budget between the two sides at
-//! each step (so any `N` works, not just powers of two); the bisection tree is
-//! the future proof-aggregation tree. On recursion we apply **cut-net
-//! splitting**: a net already cut at an upper level is restricted to its pins
-//! within each half so it is not recounted deeper.
-//!
-//! **Multilevel coarsening.** Each individual bisection is solved with a
-//! multilevel V-cycle rather than flat local search: we *coarsen* the
-//! sub-hypergraph by repeatedly merging tightly-coupled blocks into
-//! supervertices (heavy-edge matching) until only a few hundred remain, decide
-//! the cut once on that tiny graph (greedy graph-growing + Fiduccia–Mattheyses
-//! to convergence), then *uncoarsen* — projecting the cut back down and
-//! boundary-refining with FM at each level. Deciding global structure on the
-//! small graph and only ever refining locally on the big ones is what keeps
-//! large environments (mathlib ≈ 631k blocks) partitioning in seconds. The
-//! partitioner is fully self-contained — no external partitioner dependency.
-
-// This module works throughout with `u32` block/vertex ids, `u64`/`u128` weights
-// (heartbeats, ingress bytes), and `f64` balance ratios. The narrowing/precision
-// casts between them are pervasive and intentional — envs are far below `u32`
-// limits and the balance arithmetic tolerates `f64` rounding — so the lossy-cast
-// lints are allowed module-wide rather than annotated at ~30 sites. The binary
-// manifest decoder maps decode failures to a single message (`map_err_ignore`),
-// and a few matching loops mutate the array they index (`needless_range_loop`).
+//! Static DAG hypergraph sharder and sub-environment extraction.

-/// partially full and a single un-equalizable block forced extra shards. Packing

-/// allows and only opens a new shard when the next block won't fit — giving

-///
-/// **How dependency overlap is packed.** We first cut a *fine* min-cut partition

-/// before moving on, so dependency-overlapping blocks are contiguous. Greedy
-/// next-fit along that order therefore packs overlapping blocks into the same
-/// shard — keeping their shared dependencies in-shard so they are not re-paid as
-/// cross-ingress — and only the thin seams between coherent runs cross a shard
-/// boundary. The cap test includes the live cross-ingress, so a shard packed
-/// "to the cap" still executes under it.

-//! Sharing tables of anonymous Constants: the canonical construction and its
-//! reference searches (`docs/sharing-minimum.md`).
-//!
-//! The compiler shares every block with the tiered canonical construction
-//! ([`canonical_sharing_tiered`], `tiered`; Lean
-//! `Ix.Sharing.Exact.canonicalSharingTiered`): phase 1 uses the fixed K16
-//! component families (`uniform`) at widths 1, 2 and 3, phase 2
-//! allocates the table slots, phase 3 re-materializes every part under the
-//! real TagN widths, and the candidate with the fewest bytes wins.
-//!
-//! The optional test-only `sharing-reference` feature also exposes the
-//! global exact minimum of
-//! `docs/sharing-minimum.md` §3, computed by the width-state search
-//! (`optimize_sharing`, `normalize_constant_sharing`, `search`). It is
-//! exponential in the candidates and is a test oracle for small inputs, not
-//! on the compiler path. Given a resolved anonymous Constant (or its ordered
-//! expanded roots), it returns the feasible backward-reference sharing
-//! encoding with the lexicographically least key
-//!
-//! ```text
-//! K(e) = (L(e), Q(e), bytes(e))
-//! ```
-//!
-//! where `L` is the byte length of the complete serialized Constant, `Q` the
-//! vector of structural term IDs (§3.2) of the table entries in stored order
-//! and `bytes` the serialized Constant. All non-sharing fields, root order and
-//! the refs/univs tables are fixed; only the table sequence and per-occurrence
-//! inline/reference choices vary. A table entry may reference only earlier
-//! entries (the backward-reference class of §3.1); this module does not claim
-//! optimality over forward-acyclic tables.
-//!
-//! Structure:
-//! - [`SharingDag`] (`dag`): collision-independent hash-consing of the
-//!   expanded roots with §3.2 structural IDs, built from expanded roots or by
-//!   bounded, validated expansion of an existing table; also the re-expansion
-//!   checks of an encoding.
-//! - `cost`: exact serialized lengths of expressions and Constants, mirroring
-//!   the writers of `serialize.rs`, and the [`Len`] overflow sentinel.
-//! - `roots`: the ordered roots of a `ConstantInfo` and its reassembly.
-//! - `dict`: the fixed-dictionary recurrence `C_M` (§5) with explicit
-//!   telescope cuts, its incremental and lazy evaluations of a growing
-//!   dictionary, and byte-least materialization.
-//! - `search`: the sparse width-state dynamic program (§6) with the proved
-//!   reductions R1/R2, the optimistic-dictionary lower bound (§4.1) and a
-//!   materialization lower bound (the test oracle above).
-//! - `uniform`: the fixed-family optimizer for a uniform Share width (phase 1),
-//!   with the old exact optimizer isolated behind the reference feature.
-//! - `tiered`: the canonical tiered construction, its checks and its
-//!   checked mode ([`ExactSharingLimits::full_check`]).
-//! - `par`: deterministic task splitting for [`Parallelism`]; `prof`: phase
-//!   timers behind the `sharing-profile` feature.
-//! - `oracle` (tests only): a tiny exhaustive reference search; `mss` (tests
-//!   only): the maximal-structural-sharing reference encoding.
-//!
-//! Every limit in [`ExactSharingLimits`] is enforced with deterministic
-//! counters where it applies (`max_candidates` and the layer and transition
-//! limits bound the width-state search only); exhausting one returns
-//! [`SharingError::ResourceExhausted`] and never a best-so-far encoding.
-//! Lengths use checked arithmetic or the exact overflow sentinel [`Len`].
-//!
-//! # Pinned interpretations
-//!
-//! These choices are part of the canonical result and must match any other
-//! implementation of the rule:
-//!
-//! - **ID domain.** Structural IDs number exactly the distinct subterms
-//!   reachable from the ordered roots after expansion. Entries of an
-//!   incoming table that no root reaches are validated but do not receive
-//!   IDs, so they cannot influence `Q`.
-//! - **Admission.** Expansion accepts only the backward-reference class:
-//!   a Share in entry `i` must name an entry `< i`, a Share in a root must
-//!   name an entry `< len`. Out-of-range, forward and cyclic references are
-//!   [`MalformedSharing`] errors, including in unreachable entries.
-//!   The reference `optimize_sharing` rejects any Share leaf in its input.
-//! - **Byte tie.** For a fixed table sequence each entry and root is
-//!   materialized as its byte-least minimum-length representation. This
-//!   equals the rule: an inline constructor precedes a Share of the same
-//!   length (flags `0x0..=0xA` < `0xB`); among telescope prefixes of one
-//!   node the least TagN header bytes win (distinct prefix lengths always
-//!   differ inside the header); then children independently.
-//! - **Variable length.** [`UniformSharingResult::variable_len`] is the sum of
-//!   the root encodings, the table's TagN count and the entry encodings; the
-//!   rest of the Constant is fixed and checked against `Constant::put`.
-//!
-//! Pruning (the §4.1 bound strengthened with `share_width(k)` for future
-//! entries, the materialization bound, and the greedy upper bound seed)
-//! never changes a successful result, only which inputs finish
-//! within the limits; `search` documents the proofs.

-//! The fixed-dictionary optimizer `C_M` (§5) and byte-least materialization.
-//!
-//! For a dictionary `M` (available terms and their Share widths), `C_M(t)`
-//! is the minimum length of a standalone expression expanding to `t`. The
-//! options at `t` are a Share of `t` (if available) and its inline
-//! constructor. For App, Lam and All the inline constructor is a telescope
-//! over the maximal same-family spine `t = t_0, t_1, ..., t_l` (App follows
-//! the function, Lam/All the body; `t_l` is the first node of another
-//! constructor). A telescope of `j` spine nodes costs its TagN header for
-//! `j`, every side child's standalone cost (App arguments; Lam/All contract
-//! byte plus binder type), and its head: for `j < l` the head `t_j` continues
-//! the family, so the canonical writer would merge any inline form of it
-//! back into the telescope and the only legal head is a Share of `t_j`; for
-//! `j = l` the head is the natural tail at its standalone cost. Every
-//! canonical telescope boundary is one of these cases, so the recurrence is
-//! complete; it is sound because each case is realized by a concrete
-//! expression that the canonical writer emits with exactly that header.
-//!
-//! Children are standalone expressions and their lengths add, so the
-//! recurrence runs bottom-up in term-ID order (children have smaller IDs).

-//! Exact table selection and ordering (§6): the width-state search for the
-//! global minimum of `docs/sharing-minimum.md` §3. Exponential in the
-//! candidates, it is a test oracle for small inputs (and the reference of
-//! the uniform optimizer's tests), not on the compiler path.
-//!
-//! A width state assigns each stored term the Share width of its index. By
-//! §6.2 every future length depends only on the state, so histories reaching
-//! one state merge: the state keeps its least accumulated body length `F`
-//! and, among histories of that length, the least term-ID prefix. States are
-//! sparse sorted `(term, width)` vectors, expanded layer by layer (layer `k`
-//! holds states with `k` entries) in sorted key order, so work counters and
-//! failures are deterministic.
-//!
-//! Candidates are the terms that some minimum may store: R1 drops terms with
-//! one expanded occurrence and R2 terms whose inline encoding is one byte.
-//! Both reductions strictly shorten any encoding that violates them, so they
-//! preserve every minimum-length encoding and hence the canonical key.
-//!
-//! # Pruning
-//!
-//! A state is dropped only if a lower bound on every completion is strictly
-//! above the length of a feasible encoding, so states that could tie the
-//! minimum survive for the tie-break. Two bounds are used; either may prune.
-//!
-//! **Dictionary bound (§4.1).** At state `M` with `k` entries every later
-//! entry has an index `>= k`, hence a Share width `>= share_width(k)`. Let
-//! `M+` extend `M` with every absent candidate at width `share_width(k)`
-//! (the plan's width 1 is the case `k < 8`). `C` is antitone in
-//! availability and monotone in widths, later bodies cost `>= 0` and the
-//! table count prefix never shrinks, so every completion has length at
-//! least `F(M) + tag0(k) + sum C_{M+}(root)`. For a successor
-//! `M + (t, share_width(k))` the same sum is still a lower bound, because
-//! `t` keeps the width `M+` gave it and other widths only grow.
-//!
-//! **Materialization bound.** Let `E(M)` be the terms that occur in the
-//! expansions of the entries of `M`. Those entries emit only terms of
-//! `E(M)`. Every other term `t` must still have its constructor emitted
-//! inline at least once, in a later entry or a root: follow any occurrence
-//! through Shares until a representation emits it. Pick one such emission
-//! per non-leaf `t` outside `E(M)`. It owns bytes no other picked emission
-//! owns: `t`'s own bytes (Prj/Let headers, a Lam/All contract byte) and, at
-//! each child position that holds a leaf, that leaf's inline encoding or a
-//! Share (at least one byte for a candidate leaf; the inline length for any
-//! other leaf, since only candidates are ever stored). An App/Lam/All node
-//! that is never the same-family spine child of any parent starts a
-//! telescope wherever it is emitted inline, so its picked emission also owns
-//! one header byte (a "header top"). No other telescope header and no Share
-//! byte at a non-leaf position is counted. Each root position adds bytes not
-//! yet counted: a leaf root as a leaf position; a root in `E(M)` contains no
-//! picked emission, so its whole representation, at least `C_{M+}(root)`;
-//! an App/Lam/All root outside `E(M)` that is not a header top, its
-//! telescope header or Share byte; any other root outside `E(M)`, a Share
-//! or unpicked header byte at every position except possibly the one
-//! holding its picked emission. The picked bytes lie outside the bodies
-//! counted by `F(M)`, so `F(M) + tag0(k) + (picked) + (root bytes)` bounds
-//! every completion.
-//!
-//! Both bounds hold for every completion by candidates, and every
-//! minimum-length encoding is such a completion of each state on its path,
-//! so no state on the path of a minimum is ever pruned.
-//!
-//! # Upper bounds
-//!
-//! The initial feasible length is the lesser of the unshared encoding and a
-//! deterministic greedy table sequence. They only tighten pruning; neither is
-//! returned unless the search certifies it.

-//! Tiered canonical sharing: uniform-width selection, slot allocation and
-//! re-materialization under a Share layout.
-//!
-//! A rule-for-rule port of the Lean `Ix/Sharing/Exact/Tiered.lean`.
-//!
-//! The one layout, [`ShareLayout::TagN`], prices a Share at table index `i` by
-//! the wire width of the TagN Share code ([`tagn_width`]: 1, 2, 3, 4, 5 or 9
-//! bytes, the width of `TagN::put(4, 0xB, i)`). The output is written with
-//! that code, so its price is its serialized length, which is checked.
-//!
-//! **Width selection.** Phase 1 runs at each uniform width `w` in 1, 2, 3,
-//! each result is carried through phases 2 and 3, and the construction
-//! returns the candidate with the fewest final layout bytes; ties go to the
-//! lower `w`, then `set_prec` on the stored set. Every limit and every
-//! length check of phases 1-3 applies to every candidate, and an error at
-//! any width fails the call (with the lowest failing width's error); the
-//! self-checks of the built expressions apply to the returned candidate
-//! (see "Checks"). Each candidate is exact per phase as described below;
-//! the final choice is the real-byte minimum over the three candidates, not
-//! a global optimum. One candidate is `tiered_at` (Lean `tieredAtWidth`).
-//!
-//! **Phase 1 (selection).** The stored set is the least uniform-`w` minimum
-//! over the fixed K16 initial-component families. Phase 2 reads only
-//! what the phase-1 expressions contain, so they are not built: the dry run
-//! (`UniformPlan::shares`) reports it from the same decisions.
-//!
-//! **Phase 2 (slot allocation).** From the phase-1 output, `ref(t)` counts
-//! the `Share(t)` in its entries and roots; `t` depends on `u` when `t`'s
-//! phase-1 body contains `Share(u)`. The first tier is a maximum-`ref` set
-//! of at most 8 stored terms closed under dependencies (ties: order stored
-//! terms by `ref` descending then ID ascending, and prefer the set that
-//! contains the first term where two sets differ), found by branch and
-//! bound. The table is the first tier in pinned priority order, then the
-//! rest in the Kahn priority order: repeatedly the available entry (every
-//! entry its phase-1 body references already placed) with the largest
-//! `ref`, ties by the smaller ID. If that order's reference cost
-//! `sum ref(t) * width_at(index t)` exceeds the phase-1 order's, the phase-1
-//! order is kept. The final order is checked to respect the dependencies.
-//!
-//! **Phase 3 (re-materialization).** Every entry is re-encoded with `C_M`
-//! under the entries before it, priced by `width_at(index)`, and the roots
-//! under all entries; byte-least ties. The result is checked to be no
-//! longer (in layout bytes) than phase 1. The selection needs only the
-//! lengths, so only the returned candidate's expressions are built
-//! ([`finish`]).
-//!
-//! When the order is closed under stored descendants (every stored
-//! descendant of an entry precedes it; `descendant_closed` decides it in one
-//! pass), the cost and choice of every term below entry `j` are the same
-//! under the prefix `order[..j]` as under the whole table (Lean
-//! `gCost_local`), so one evaluation of the whole table gives every task:
-//! entry `j` with its own Share hidden, the roots as they are (the one-pass
-//! phase 3). Every order of Init and Mathlib is closed. An order that is not
-//! is evaluated per prefix (`per_prefix_tasks`): one evaluation of each
-//! prefix, maintained from one prefix to the next. Such an order needs an
-//! entry whose phase-1 body does not reference a stored descendant, which
-//! takes a tie between a telescope cut at that descendant and a longer
-//! telescope, so a telescope spine of at least 1,032 nodes (the 3-byte
-//! header rung).
-//!
-//! # Checks
-//!
-//! In the default mode (the compiler's), every candidate (`tiered_at`) is
-//! checked, in this order, for:
-//!
-//! 1. phase 1: the telescope-spine bound, the length domain, `states`,
-//!    `work`, `knapsack_cells`, `output_bytes` (on the model length) and the
-//!    model length against the full evaluation;
-//! 2. the phase-1 dry run: the consistency of the decisions, `input_nodes`
-//!    on the expression nodes the phase-1 build would allocate (what the
-//!    re-expansion check of the built expressions charges) and the domain of
-//!    the real length;
-//! 3. phase 2: `states` of the first-tier search and the dependency order;
-//! 4. phase 3: `work` of the evaluations (and, per prefix, of the
-//!    decisions), the domain of the length, the length against phase 1,
-//!    `input_nodes` on the expression nodes the build allocates (exact per
-//!    prefix; in one pass bounded by twice the length and counted exactly
-//!    only when that bound exceeds the limit) and `output_bytes`.
-//!
-//! The returned candidate alone ([`finish`]) is then checked for:
-//!
-//! 5. the one-pass decisions and their `work`, added to the candidate's;
-//! 6. the build of its expressions;
-//! 7. their layout price against the evaluated length;
-//! 8. their re-expansion to the DAG and the stored terms, with as many
-//!    expression nodes as counted;
-//! 9. their serialized length (`put_expr`) against the evaluated length.
-//!
-//! The phase-1 expressions are never built, and checks 5-9 do not run for
-//! the two other candidates; their limits are checked with the same counts
-//! as the returned candidate's, except the work of check 5. A wrong length
-//! of another candidate would change the selection without an error; the
-//! checked mode exists to show that this does not happen.
-//!
-//! With [`ExactSharingLimits::full_check`] (the checked mode) every
-//! candidate also builds its phase-1 expressions from the same decisions,
-//! checks them as `optimize_uniform` does (re-expansion, real length) and
-//! compares them with the dry run (the Shares of each entry, the entries
-//! each entry shares, the expression nodes, the real length and the layout
-//! price); a one-pass candidate is also evaluated per prefix and its task
-//! lengths and decisions are compared; and checks 5-9 run for every
-//! candidate, the returned one first (the work of check 5 is charged to the
-//! returned candidate only, as in the default mode, so every limit has the
-//! outcome it has there). The output and the result equal the default
-//! mode's; any discrepancy is an internal error.

-//! Canonical family sharing under a uniform Share width.
-//!
-//! Production uses the fixed K16 family in `family`. The old unbounded
-//! uniform optimizer and its controls live in `reference`, available only
-//! to unit tests or the explicit test-FFI reference feature.
-//!
-//! Cost model: every `Share` costs exactly `w >= 1` bytes regardless of its
-//! index; the table count is an exact TagN; telescopes and every other byte
-//! are as written by `put_expr`. The model length of a stored set `S` is
-//! `tag0(|S|) + sum_{t in S} inl_S(t) + sum_roots C_S(r)`, where `inl_S(t)`
-//! is `t`'s cost with an inline top. Order does not affect it: in any order
-//! with stored descendants first each entry sees every stored term that can
-//! occur inside it, and a Share's price does not depend on its index. Only
-//! the set is chosen; the table order is then pinned (stored descendants
-//! first, then larger in-degree, then smaller structural ID).
-//!
-//! # Canonical class and classification
-//!
-//! * `deg(t)`: compact in-degree, with edge multiplicity and root
-//!   occurrences; head positions are the root occurrences and the edges
-//!   that do not continue a telescope (an App as the function of
-//!   an App, a Lam as the body of a Lam, an All as the body of an All);
-//!   `occ(t)`: expanded occurrences; `size(t)`: unshared standalone length.
-//! * The production result minimizes over the fixed initial component
-//!   families, with certain-stored entries held fixed. The reference oracle
-//!   minimizes over all tables whose entries have in-degree >= 2.
-//!   In-degree-1 terms are left out by an exchange that never
-//!   increases the length (store the single parent instead, or turn extra
-//!   writes of a stored parent into Shares), so this class contains a
-//!   global minimum; ties can also store an in-degree-1 term, which this
-//!   definition excludes.
-//! * CERTAIN-EXCLUDED when `(occ-1)*size < occ*w` (in no minimum).
-//! * Candidates: in-degree >= 2 and not certain-excluded.
-//! * CERTAIN-STORED (in every minimum of the restricted class) when the gain
-//!   bound `g >= theta`, with `d`, `h` the visible counts and lower bounds
-//!   computed bottom-up pricing every candidate child at `min(w, .)`, every
-//!   other child at its inline bound and a header of at least 1 byte:
-//!   non-telescope `g = (d-1)*inl - d*w`; telescope with `h >= 1`
-//!   `g = (d-1)*b + (h-1) - d*w`; telescope with `h = 0`
-//!   `g = (d-1)*b - tag4(spine length) - d*w`.
-//!   Visible counts `(d, h)` for a maybe-stored set `M` (the candidates):
-//!   one per root occurrence plus, per edge from `z` (head edges only for
-//!   `h`), 1 if `z` is in `M`, else `min(d(z), 2^20)`.
-//!   Threshold: with `theta_max = 1 + tag0_step_bound(#candidates)` (2 below
-//!   4311826560 candidates), `theta = 1` when `tag0(#candidates) = tag0(#terms
-//!   with g >= theta_max)`, else `theta = theta_max`.
-//! * UNCERTAIN: the other candidates; LOW-DEGREE: the other terms.
-//!
-//! Certain-stored terms cost exactly `w` wherever they occur (`g >= 1`
-//! forces their merged payload bound `>= w`), so costs above them are
-//! evaluated with them as `w`-byte leaves that end telescopes.
-//!
-//! # Search
-//!
-//! Uncertain terms joined by a DAG path avoiding certain-stored terms form
-//! a component; costs are sums of per-component functions. Each component
-//! search returns, per chosen count, its best change within `slack =
-//! tag0(|certain-stored| + |uncertain|) - tag0(|certain-stored|)` of its
-//! optimum. The table-count prefix is the only coupling: when the combined
-//! choice reaches a TagN bracket of 128 or more entries, a knapsack over
-//! components checks the lower brackets.
-//!
-//! Production enumerates every subset up to sixteen initial members and
-//! otherwise keeps every count of the setPrec-least greedy chain. The old
-//! reference component search is the reclassifying branch and bound of Lean
-//! implementation. At each node it (1) recomputes the bounds and visible
-//! counts over the component's area with the members decided "not stored"
-//! removed from `M`, and forces
-//! "stored" every undecided member with `g >= theta`; (2) bounds the node by
-//! the cost with every undecided member available and its entry free,
-//! pruning only when strictly above the best by more than `slack`; (3)
-//! splits the undecided members into groups joined by DAG paths through
-//! non-opaque terms (a decided-stored member is opaque when its `inl` (or,
-//! for a telescope, merged) bound is at least `w`; groups below a stored
-//! non-opaque member are joined), solving groups by memoized sub-searches
-//! keyed by the group and the decisions that reach it; (4) branches on the
-//! undecided member with the largest `|g|` (then the smaller ID), "stored"
-//! first when `g > 0`. Per-count tables of groups combine by convolution.
-//! The plain subset enumeration is kept as a test oracle
-//! (`ExactSharingLimits::uniform_subset_search`); it is not on the compiler
-//! path, and the Lean optimality theorems assume it is off.
-//!
-//! # Tie-break
-//!
-//! Among minimum-length sets the least in the order "the smaller structural
-//! ID of the symmetric difference is not stored". It decomposes over
-//! components and through the knapsack.
-//!
-//! # Numeric domain
-//!
-//! Lean uses unbounded `Nat` and `Int`, and so does this optimizer: costs,
-//! bounds, gains, component deltas and knapsack sums are computed in `u128`
-//! and `i128` first and, if a value leaves that range, again in `BigUint`
-//! and `BigInt` (`arith`), with the same result wherever the first run
-//! succeeds. The exclusion test is evaluated exactly even when an
-//! occurrence count saturates, and visible counts are `u128`, below `2^84`
-//! for any DAG held in memory. Only the model length of the chosen set must
-//! be a `u64`: it is the length of an output.

-//! The integers of the phase-1 optimizer, in two representations.
-//!
-//! Lean computes phase 1 with `Nat` and `Int`. Its values are lengths,
-//! lower bounds and occurrence-weighted sums, which are nonnegative, and
-//! differences of them. Intermediate values can be exponential in the size
-//! of the input while the chosen encoding stays small: with no uncertain
-//! term stored, `x_(i+1) = App(x_i, x_i)` unfolds to about `2^i` bytes.
-//!
-//! [`Fast`] computes in `u128` and `i128`. Nonnegative sums saturate at
-//! `u128::MAX`; saturation is monotone, so a saturated summand can lose a
-//! comparison but a value that is not `u128::MAX` is exact, and the
-//! optimizer reports [`FormatBound::LengthOverflow`] as soon as a value it
-//! keeps is `u128::MAX`. Signed operations and conversions are checked and
-//! report the same error. [`Exact`] computes the same values as [`Nat`] and
-//! [`Int`], unbounded, and never overflows.
-//!
-//! The optimizer runs with [`Fast`] and, if that run reports
-//! `LengthOverflow`, runs again from the same meter with [`Exact`]
-//! (`family::optimize_at`). A [`Fast`] run that succeeds computed every value
-//! exactly, so its result is the [`Exact`] one: the representation changes
-//! the time, never a successful result.

-//! `AnonEnv<'a>` — restricted view over `IxonEnv` exposing only the
-//! anonymous (metadata-free) sections.
-//!
-//! Held in lieu of `&IxonEnv` everywhere the anon-mode kernel needs
-//! env access (constant materialization, blob lookup, dependency
-//! walking). Crucially, it does **not** expose `named`, `names`, or
-//! `comms` — Lean.Name → metadata mappings that the anon kernel must
-//! never consult.
-//!
-//! Two construction paths:
-//!
-//! 1. [`AnonEnv::from_env`] — borrowed view over an existing
-//!    `IxonEnv`. The full env may still have metadata sections
-//!    populated, but anon-mode code can't reach them through this
-//!    wrapper.
-//!
-//! 2. [`Env::get_anon`] (Phase 3) — built fresh from `.ixe` bytes
-//!    with the named/names/comms sections skipped during load.
-//!
-//! Either way, code parameterized over `&AnonEnv<'_>` is structurally
-//! prevented from accessing metadata.

-//! Anon-mode work enumeration over `IxonEnv::consts`.
-//!
-//! Identifies the set of kernel-checkable target addresses without
-//! consulting any metadata sections (`named`/`names`/`comms`), so it
-//! works against an env loaded via [`ixon::env::Env::get_anon`].
-//!
-//! The set produced here is the canonical work set for anon-mode
-//! typechecking: it matches `rs_kernel_check_anon` in
-//! `crates/ffi/src/kernel.rs` and is what an Aiur-style verifier
-//! commits to. Callers iterate the returned `Vec<AnonWorkItem>` and
-//! invoke `IxonChecker::check_const` on each item's `primary` address;
-//! the kernel's internal block coordination handles checking every
-//! member + ctor of `Block` items.
-//!
-//! ## Enumeration rules
-//!
-//! For each entry in `env.consts`:
-//! - Projection variants (IPrj/CPrj/RPrj/DPrj) are skipped — they're
-//!   covered by checking their parent Muts block.
-//! - Standalone variants (Defn/Recr/Axio/Quot) emit one `Standalone`
-//!   work item with the constant's own address.
-//! - Muts blocks materialize to enumerate members, then emit one
-//!   `Block` item whose `primary` is the first member's projection
-//!   address (and `targets` includes that primary plus every other
-//!   member's projection plus one CPrj per constructor of each
-//!   inductive member). Checking the primary triggers the kernel's
-//!   block-coordination logic which covers every target.
-//!
-//! Dispatch on the outer `TagN` byte via
-//! [`ixon::lazy::LazyConstant::peek_variant`] avoids body parse +
-//! `Arc<Expr>` allocation for the ~95% of constants that are
-//! standalones or projections.

-//! Positive-only batched lambda/forall congruence.

-//! Domains are compared under the already-accepted prefix, before adding
-//! the SAME fresh local to both sides. The terminal bodies are opened once.
-//! Each accepted binder therefore follows the existing single-binder rule.
-//! See Ix/Tc/Verify/DefEq/Structural.lean (quickBinder_wf) and the lamDF /
-//! forallEDF rules in lean4lean. Those proofs do not certify this Rust loop.
-//!
-//! This is not a complete conversion procedure for binder terms: skipping
-//! intermediate conversion can miss reduction/proof-irrelevance/cache wins.
-//! A false or exhausted probe falls back to the original single-binder path,
-//! with batching disabled throughout that fallback. No pending/suffix pair
-//! is published equal, and no failed probe is published as an inequality.

-//! Conservative declaration summaries for proof-irrelevance eligibility.

-//! For a syntactic telescope `c : (x1 : A1) ... (xn : An) -> T`, the
-//! classifying sort of T determines whether c, and each of its first n
-//! partial applications, can be a proof: `imax a b` is zero iff b is zero.
-//! We recognize T's sort ONLY from Sort nodes or syntactic types of its
-//! constant/bound-variable head. No delta, reduction probes, fresh locals,
-//! or argument validation occur here. Unknown means use ordinary inference.
-//!
-//! The substitution lemma justifies transferring a known nonzero sort to
-//! well-typed arguments. This is NOT a typechecking shortcut: all arguments,
-//! declaration types/bodies and universe scopes still undergo normal checks.

-  //   pass and during `compute_is_rec`).
-  // - Their constructors (needed for ctor lookups keyed on the block).
-  // - Their recursors (needed by `find_peer_recursors` during
-  //   `generate_block_recursors`'s rule generation — without recs in
-  //   the block, rule RHS construction returns None and the stored
-  //   rules can't be verified).
-  //
-  // **Order matters for inductives and recursors.** `discover_block_inductives`
-  // filters the block's member list down to `KConst::Indc` entries
-  // and the resulting order drives `build_flat_block` → `build_rec_type`
-  // → motive-binder emission in `generate_block_recursors`. That
-  // order must match whatever order the *stored* recursor was
-  // generated against.
-  //
-  // For `orig_kenv` (what this function builds), the stored recursor
-  // is Lean's own — generated against the **declaration order** given
-  // by each constant's `all` list (the source order the user wrote
-  // the mutual block in). If `discover_block_inductives` returns
-  // members in any other order, the generated motive prefix permutes
-  // relative to Lean's, yielding spurious `check_recursor: type
-  // mismatch` on every mutual-block recursor (we saw this on
-  // `Lean.Xml.Content.rec`, `Lean.Compiler.LCNF.Code.rec`, every
-  // `Grind.Arith.*.*Cnstr*.rec`, etc.).
-  //
-  // The compiler stores each block in this same declaration order.
-  // Iterating `lean_env` directly to push each constant's `self_kid` gave
-  // random (FxHashMap iteration) order; we now seed each block with
-  // its `all` list the first time any member is observed, then
-  // append ctors and source-ordered recursors in a second pass. The
-  // inductive and recursor subsequences must align positionally with the
-  // flat block (original `.all` members, then source-walk nested auxes).
-  //
-  // `ixon_ingress` builds an analogous list from each block's stored
-  // `Muts` entry, in stored member order. The two kenvs differ in how
-  // recursor generation opens a nested occurrence of an external
-  // inductive (`RecursorAuxOrder`): this one opens the head alone, an
-  // Ixon-ingressed one the head's whole stored block.

-//! Universe levels with optional metadata and Géran's canonical-form comparison.
-//!
-//! `KUniv<M>` is an Arc-wrapped universe level. Each variant carries a
-//! monotonic intern-table UID (`Addr = u64`) for hash-consed identity.
-//! `Param` carries a positional `u64` parameter index plus `M::MField<Name>` —
-//! the parameter name in Meta mode, erased to `()` in Anon mode.
-//!
-//! # Relationship to Lean4Lean
-//!
-//! `normalize_level` is a line-by-line port of Lean4Lean's `Level.Normalize`
-//! (see `refs/lean4lean/Lean4Lean/Level.lean`), based on Yoan Géran's paper
-//! "A Canonical Form for Universe Levels in Impredicative Type Theory"
-//! (<https://lmf.cnrs.fr/downloads/Perso/long.pdf>). The Rust `NormLevel` is
-//! a `BTreeMap<Vec<u64>, Node>` indexed by sorted param-index paths — the
-//! Rust analogue of Lean4Lean's `Std.TreeMap (List Name) Node`, with `u64`
-//! param indices replacing `Name` since our anon-mode params are positional.
-//!
-//! Point of divergence: `norm_level_le` is intentionally stronger than
-//! Lean4Lean's `NormLevel.le`. Lean4Lean's variant looks for a *single*
-//! `p2 ⊆ p1` entry in `l2` that dominates both the constant and the variable
-//! contributions of `n_p1`; ours splits that into independent per-ingredient
-//! searches (`covers_const` and `covers_var`). See the detailed doc on
-//! `norm_level_le` for the concrete witness that motivated the change.
-//!
-//! This is a soundness-preserving completeness strengthening, not a
-//! disagreement with the canonical-form theory: Lean4Lean's
-//! `NormLevel.subsumption_eval` is `sorry` in
-//! `refs/lean4lean/Lean4Lean/Verify/Level.lean:545`, and there is no
-//! `geq'_wf` / `NormLevel.le_wf` theorem anywhere in the Verify tree, so the
-//! "complete for level algebra" claim in Lean4Lean's `divergences.md` is
-//! aspirational for `geq'` specifically. `univ_eq` (via `norm_level_eq`)
-//! matches Lean4Lean's `isEquiv'` bit-for-bit, since that direction *is*
-//! proven sound (`isEquiv'_wf`, `Verify/Level.lean:578`) and the witness
-//! that exposed `NormLevel.le`'s gap is not an equality case.

-/// # Divergence from Lean4Lean
-///
-/// Lean4Lean's `NormLevel.le` (`refs/lean4lean/Lean4Lean/Level.lean:164`)
-/// looks for a *single* `p2` covering both `n1.const` and `n1.var`
-/// simultaneously — sound, but incomplete. Concrete witness (see
-/// `prop_univ_max_is_geq_both_components_imax_witness`):
-///
-/// ```text
-/// a = Succ^3(0)
-/// b = imax(imax(a, Param 0), Param 1)
-/// m = max(a, b)
-/// ```
-///
-/// After normalization + subsumption:
-///
-/// ```text
-/// normalize(m): [] → const=3, [1] → var=[(1,0)], [0,1] → var=[(0,0)]
-/// normalize(b): [] → const=0, [1] → var=[(1,0)], [0,1] → {const=3, var=[(0,0)]}
-/// ```
-///
-/// Checking `b ≤ m` at `p1 = [0,1]` needs both `const=3` and `var=[(0,0)]`.
-/// `m[[]]` covers the const (no var); `m[[0,1]]` covers the var (const was
-/// zeroed out by subsumption against `m[[]]`). No single `p2 ⊆ [0,1]` in
-/// `m` has both, so Lean4Lean's `le` reports `m ≱ b` even though `m ≥ b`
-/// holds for every parameter assignment.
-///
-/// The version here splits the check into `covers_const` and `covers_var`,
-/// each searching `l2` independently. This is sound:
-///
-/// - For `n1.const = C`, if some `p2 ⊆ p1` has `n_p2.const ≥ C`, then along
-///   any `ρ` with `p1` active, `p2` is active too, so `l2`'s total already
-///   includes `n_p2.const ≥ C`. Same argument for the fallback clause
-///   `v.offset + 1 ≥ C` with `v ∈ n_p2.var`, because every `v` inserted
-///   during `normalize_aux` has `v.idx ∈ p2` (so `u_v ≥ 1` in an active
-///   branch).
-/// - For each `(w, off) ∈ n1.var`, if some `p2 ⊆ p1` has `(w, off') ∈
-///   n_p2.var` with `off' ≥ off`, then `l2`'s contribution along active
-///   `p1` is at least `u_w + off' ≥ u_w + off`.
-///
-/// This matches what Lean4Lean's paper-level theory expects but its
-/// implementation doesn't cover (cf. the `sorry` on
-/// `NormLevel.subsumption_eval` in `Verify/Level.lean:545`, and the absence
-/// of any `geq'_wf`).

-//! Performance counters for cache hit-rate and fuel-consumption analysis.
-//!
-//! The environment counters below use `IX_PERF_COUNTERS=1`; the separate
-//! [`same_head`] diagnostic uses `IX_SAME_HEAD_PROFILE=1`.
-//! When the variable is unset (production default), every recording call is a
-//! single inlined branch on a `LazyLock<bool>` and skips the atomic increment
-//! entirely. When set, the counters track:
-//!
-//! - `whnf_cache` and `whnf_no_delta_cache` hit/miss counts (audit §10).
-//! - `infer_cache` and `infer_only_cache` hit/miss counts.
-//! - `def_eq_cache` hit/miss counts.
-//! - `def_eq_failure` set hit and insert counts.
-//! - Per-constant peak `MAX_REC_FUEL` consumption (running max across all
-//!   constants checked, plus a total for averaging).
-//!
-//! Counters live on [`KEnv`](super::env::KEnv) and are dumped on `Drop` when
-//! enabled, so a single `IX_PERF_COUNTERS=1` invocation of any harness that
-//! tears down the kernel env (e.g. `rs_kernel_check_consts`) prints a summary
-//! at the end.
-//!
-//! ## Why atomic counters even though we run per-constant in parallel?
-//!
-//! `KEnv` is shared across many `TypeChecker` threads, so the simplest
-//! observability story is shared atomic counters. The `Ordering::Relaxed`
-//! increment cost is negligible compared to the work being measured (cache
-//! probes themselves involve DashMap shard locks which dwarf an atomic add).
-//! When `IX_PERF_COUNTERS` is unset the lazy bool short-circuits even the
-//! atomic op.

-//! Native role admission. Wire decoding, candidate preparation and semantic
-//! admission are distinct boundaries: a prepared source authenticates its
-//! binding and every bound record, and only the group validators in
-//! `groups` admit roles, a whole specification group at a time.
-//!
-//! # The certified checker's frontend, as this kernel reads it
-//!
-//! The certified checker reads an artifact as a stream folded in order, with
-//! a committed prelude in front. Its frontend has six checks this kernel must
-//! match. This kernel reads an artifact as content-addressed units checked
-//! independently, with the bound roles admitted first, so each check is
-//! either enforced here or ruled out by that representation:
-//!
-//! - **The prelude's shape** (the prelude names the pinned prelude roles) and
-//!   **the prelude copy** (a stream may not hold, at a prelude key, anything
-//!   but the prelude's entry): every prelude role ([`PRELUDE`]) must be bound
-//!   and its group admitted, or no unit of the artifact is checked
-//!   ([`ArtifactSource::prelude_refusal`]). The prelude's records are not
-//!   compared with a committed copy: the group validators compare them with
-//!   the same specifications the committed prelude was checked against, and
-//!   a bound address holds exactly one record.
-//! - **The rest-only hoist** and **the hoist guard** reorder a stream so that a
-//!   `Nat` operation's ground precedes it, outside the prelude and without
-//!   splitting a unit. Nothing here depends on order: groups are admitted in
-//!   dependency order before any unit is checked, whatever order the records
-//!   come in, and units are never split or merged.
-//! - **The units check** declines a basis record of the fold's own, a unit out
-//!   of shape, a prelude role declared past the front, and two units declaring
-//!   a common base. This kernel has no fold-own records and no generated model
-//!   records; a unit is a serialized record, whose recursive targets come from
-//!   the unit itself; a role's records are its bound addresses, one record
-//!   each; and a projection is authenticated against the one owner its address
-//!   commits to, so no two units declare one declaration.
-//! - **The inferer's fuel** bounds the checker's untyped inference over model
-//!   records. This kernel has no untyped inference: every inference and
-//!   reduction is typed and bounded by fuel, the WHNF step limit and the stack
-//!   check, so a non-terminating head β in a declared type declines.

-//! Group validators. Each admits one specification group of a binding for a
-//! source, or refuses it with a reason. The groups and their specifications
-//! are the certified checker's:
-//!
-//! - a basis block (`Nat`, `Eq`, `PUnit`, `Empty`, `False`, `Quot`) or a
-//!   standard axiom's family (`Iff`, `Nonempty`) is admitted only when
-//!   every bound role authenticates as the carried record at the position
-//!   the specification fixes (an inductive's unit holding nothing else, its
-//!   constructors by index, the quotient records by kind); the
-//!   declarations, read into a fresh anonymous environment, are exactly the
-//!   specified ones built from the bound addresses; and the kernel checks
-//!   them there with only the groups admitted before this one. Every role a
-//!   standard axiom's type mentions is such a block: an admitted axiom is
-//!   true only of the declarations it quantifies over, so a type does not
-//!   pin them;
-//! - an anchor (the literal support, `Bool`, `True`, `And`) is admitted only
-//!   when its record authenticates, is not unsafe, has exactly the specified
-//!   level count and type, and that type checks as a type with only the
-//!   groups admitted before it. An anchor is specified by its type alone;
-//!   its declaration is checked like any other once admitted;
-//! - an axiom (`propext`, `Classical.choice`, the inert `sorryAx`) is
-//!   admitted only when its record is a safe axiom of exactly the specified
-//!   level count and type over the admitted groups, and checks.
-//!
-//! A group is admitted whole or not at all, after the groups it needs.
-//! Nothing outside this module creates an admission.

-//! Substitution and lifting for zero kernel expressions.
-//!
-//! All functions intern results through `InternTable` for pointer
-//! deduplication. In addition, the traversal itself is memoized by
-//! content hash for the duration of a single call — expressions are
-//! content-addressed DAGs and the same sub-expression may appear many
-//! times (well-founded-recursion unfolds, recursor rules with repeated
-//! motives, etc.); without per-call memoization we re-walk every shared
-//! occurrence, turning a DAG walk into a tree walk and blowing O(N)
-//! sharing into O(2^k) work. Mirrors `lean4lean`'s `replaceM` which
-//! uses a `PtrMap Expr Expr` for the same reason (see
-//! `refs/lean4lean/Lean4Lean/Expr.lean:14`).

-    //   Acc.intro fields = 1 (h)
-    //   Rule rhs: λ motive intro_case h, intro_case ... h ...
-    //
-    // The lean4lean rule rhs for Acc.rec.intro is:
-    //   λ motive intro_case h, intro_case (Acc.intro-major-x) h (λ y hr, Acc.rec motive intro_case y (h y hr))
-    // But x comes from the major argument's decomposition, substituted for the index.
-    //
-    // This is getting very complex. Let me use a different approach:
-    // Since the test just checks `Acc.rec (fun _ _ _ => p) (Acc.intro h) = p`,
-    // I can provide the rule rhs as:
-    //   λ motive intro_case h, intro_case var(?) h (λ y hr, Acc.rec motive intro_case y (h y hr))
-    //
-    // For the specific test, intro_case = (fun _ _ _ => p), so the result is p
-    // regardless of the ih computation. I just need the rule to apply intro_case.
-    //
-    // Per check_recursor, the rule's fields = 1 (the h from Acc.intro).
-    // The rhs should have motives+minors+fields = 1+1+1 = 3 lambdas.
-    // After iota: Acc.rec params are substituted, indices substituted from major,
-    // then rhs is applied to motive, intro_case, and the field (h).
-
-    // rhs: λ motive intro_case h, intro_case x h ih
-    // But x comes from the major arg decomposition — it's injected by the iota rule.
-    // Actually, looking at iota reduction code: the rule rhs takes only
-    // motives+minors lambdas, then the ctor fields are applied separately.
-    // Let me check the existing Bool.rec and N.rec rules for reference.
-
-    // Looking at Bool.rec rule: fields=0, rhs = λ motive hf ht, hf (or ht)
-    // That's motives(1) + minors(2) = 3 lambdas, 0 fields applied externally.
-    //
-    // N.rec succ rule: fields=1, rhs = λ motive h_zero h_succ n, h_succ n (rec...)
-    // That's motives(1) + minors(2) + fields(1) = 4 lambdas.
-    //
-    // So Acc.rec intro rule: motives(1) + minors(1) + fields(1) = 3 lambdas.
-    // rhs: λ motive intro_case h, intro_case x h (λ y hr, Acc.rec motive intro_case (h y hr))
-    //
-    // But where does x come from? In the iota rule for indexed types, x is
-    // substituted from the major arg. After decomposing Acc.intro applied args,
-    // the index x is known. Then the rule rhs is instantiated.
-    //
-    // Hmm, actually for Acc, the params are α and r (params=2).
-    // After iota strips params from the major, the major's ctor is Acc.intro
-    // with fields = 1 (the h argument). But x is an INDEX, not a field.
-    //
-    // The iota reduction substitutes indices from the ctor args.
-    // For Acc.intro, the constructor is:
-    //   Acc.intro : {α} → {r} → {x} → (∀ y, r y x → Acc r y) → Acc r x
-    // params = 2 (α, r), remaining args = {x} and h.
-    // But x is implicit and corresponds to the index. The field count is 1 (h).
-    //
-    // In the iota rule, after extracting params and the ctor args:
-    //   ctor_args after params = [x, h]
-    //   fields = 1 (h only)
-    //   The rule rhs takes: λ motive intro_case h_field
-    //   And x is substituted from the ctor args' index position.
-    //
-    // This is very subtle. For the test, the motive is (fun _ _ => Bool)
-    // and intro_case is (fun _ _ _ => p). So the result is just p.
-    //
-    // Let me just construct a rule that works for this case.
-    // rhs: λ motive intro_case h, intro_case x h ih
-    // where x and ih are... actually I think the rhs for indexed recursors
-    // doesn't take x as a lambda parameter — x comes from the major decomposition.
-    //
-    // Let me look at what the kernel generates for Acc.rec and match that.
-    // For now, let me try providing a rule that just applies intro_case:
-
-    // Actually, the simplest approach: provide an empty rules vec (no rules).
-    // The kernel's check_recursor will GENERATE the correct rule and compare.
-    // Since we provide no rules, the comparison will fail... unless we skip it.
-    //
-    // Hmm, that won't work. Let me just leave minors: 0 and rules: [] for now,
-    // and test only accRecNoEta (which doesn't need reduction).
-    // The accRecReduction test requires a working rule.
-
-    // For now: keep the minimal recursor (works for accRecNoEta).

-//! Tests translated from lean-kernel-arena tutorial/Tutorial.lean.
-//!
-//! Each test builds a small `KEnv<Meta>` and checks that the zero kernel
-//! correctly accepts or rejects specific constants.
-//!
-//! Organized by category:
-//! - `basic`: definitions, levels, lets, forall checks
-//! - `inductive`: good and bad inductive types
-//! - `reduction`: recursor reduction, Peano arithmetic, Bool/Nat rec
-//! - `defeq`: proof irrelevance, eta, equality

+## Retired suites
+
+Two groups of suites were retired:
+
+- those that tested the deleted Rust compiler, Rust kernel and ShardMap;
+- those whose property the certified compiler and kernel now prove.
+
+The certification proves soundness, that what is accepted is correct. It does not prove completeness, that every valid input is accepted. Completeness, and behaviour at scale, are exercised by the real-corpus runs in the merge queue:
+
+- `initstd-reference` compiles Init+Std, pins its bytes, and checks every constant with `ix check-lean`.
+- `fidelity-initstd` reads back and decompiles every record of Init+Std.
+
+Each entry below says what replaced the suite, or why it was dropped.
+
+**Dropped, because the other side is deleted:**
+
+- **The Rust differentials:** `rust-compile`, `rust-decompile`, `rust-serialize`, the `*-cross` and `*-canon-roundtrip` checks, `kernel-check-const`, `kernel-check-env`, `kernel-ixon-roundtrip`, `exact-sharing-ffi`, `shard-map`, and `check-kernel`'s codec differential (`kernel-codec`).
+
+**Dropped, because a proof or a corpus run covers them:**
+
+- **`compile-schedule-identity`** (landing). It compared three things: the wave fold at several widths, a test-only live-state reference schedule, and the streamed pipeline at 1, 4 and 16 workers. None of these comparisons is needed now:
+  - The IO pipeline computes the fold by type: `reportIO` returns `{r // r = Ix.Cert.compileReport env}` (`Ix/Compile/ReadyCompile.lean`).
+  - The fold's value doesn't depend on its width (`Ix.Cert.Schedule.compileEnvFold_width`).
+  - No other path ran the reference schedule. It isn't proved that the wave-snapshot fold equals a fold that compiles one block at a time on live state (`Ix/Cert/Schedule.lean`), but nothing compiles that way.
+- **`cert-compile-parity-initstd`** (landing). It compared `Ix.Cert.compile` with the IO pipeline and with the Rust compiler on Init+Std. The first equality is `reportIO`'s type, and the Rust compiler is deleted. `initstd-reference` pins the bytes of the Init+Std artifact.
+- **The Batteries leg of `compile-determinism`.** `initstd-reference`'s pinned digest is the stronger check across processes at scale.
+- **`check-kernel`'s level comparison.** `leqCore_sound` proves soundness, and the corpus runs exercise completeness.
+- **`check-kernel`'s quotient Source on Init and Std.** The nominal-to-quotient Source bridge is proved (`Ix.LeanIngress.NominalQuotient`, `Ix.Cert.Quotient`), and `initstd-reference`'s compile runs the same ingress on Init+Std.
+- **`check-kernel`'s Init+Std reader fidelity** (the first 20,000 records). `fidelity-initstd`'s phases 3 and 4 compare every record of Init+Std and require full source coverage.
+- **`compile-claim-conflict`.** The compile is certified (`CompileCorrect`). The corpus compiles exercise its completeness.
+- **`decompile` and `decompile-diff`.** `fidelity-initstd`'s phase 5 is the decompile round trip on Init+Std.
+- **`kernel-read-cache`.** The read cache only serves `kernel-check-ixe`'s diagnostics. The user-axiom tests run its path.
+
+**Replaced:**
+
+- **`record-decoding`.** Its refusals moved into `kernel-record-check` (primary): orphan, noncanonical and oversized records, phase precedence, and a cache beside bad bytes. `kernel-check-ixe` passes host-decoded records straight to the certified step, so these refusals aren't covered by a proof. The parallel decoder's agreement with the serial one is proved (`Ix.RoleBinding.RecordDecoding.parallel_eq`, `recordStore_eq_parallel`).

 ## Layer 2: kernel node identity (internal, ephemeral, never serialized)
 
 Inside one checker run, the kernel needs cheap identity for the
-**in-memory expression/universe nodes** (`KExpr`/`KUniv`) churned out by
-substitution, WHNF, and def-eq — for the hash-consing intern table, the
-whnf/infer/def-eq cache keys, and quick equality. These objects are
-ephemeral: they are never serialized, never compared against Ixon
-addresses, and are torn down when the `KEnv` clears.
-
-Historically this layer ALSO used blake3: every constructed node hashed
-`(variant tag ‖ child hashes)`. That was a *separate scheme* from Ixon
-addressing (a Merkle-DAG over node tags, not blake3-of-serialization) —
-the two were never interchangeable — and repeated hashing added work
-for every constructed node.
-
-Since `1e3029d`, layer-2 identity is an **intern-assigned `u64` uid**
-(`crates/kernel/src/env.rs::Addr`):
-
-- Uids come from a process-global counter and are **never reused**, so
-  `uid(a) == uid(b)` implies "same construction event or same
-  intern-table canonical value" — i.e. structural equality. Stale cache
-  keys can only miss, never alias.
-- The intern table keys on **shallow structural keys**
-  (`ExprKey`/`UnivKey`: variant tag + child uids + semantic payload),
-  mirroring exactly what the old content hash covered — display names,
-  binder info, and mdata are excluded, so interning semantics are
-  unchanged.
-- `PartialEq` for `KExpr`/`KUniv` is structural with the uid fast path:
-  canonical-vs-canonical comparison is O(1), and completeness-critical
-  `==` sites are unaffected. `hash_eq` remains the fast-but-incomplete
-  uid check for cache/quick-path callers, where a false negative only
-  costs a fallback.
-- Soundness direction: caches and def-eq quick paths rely only on the
-  affirmative ("equal uid ⇒ equal term"), which holds by construction.
-  An imperfect intern hit-rate degrades performance, not correctness.
-
-Nat/Str literal nodes keep their blake3 **blob** `Address` (that is
-layer-1 data riding on the node, used by `refs`/assumption filtering).
+in-memory expression nodes churned out by substitution, WHNF and def-eq:
+for memo keys, cache keys and quick equality. These objects are ephemeral:
+they are never serialized, never compared against Ixon addresses, and die
+with the run.
+
+IxC has one expression type, `Ix.Kernel.Expr`, whose nodes carry derived
+data as Lean `@[computed_field]`s: a hash, the loose bound- and
+free-variable bounds and a level-parameter flag, packed into one word
+(`Expr.data`; `IxC/Kernel/Cached/ExprNodes.lean`). There is no hash-consing
+table. Terms are shared by Lean's own structure sharing: an operation
+returns unchanged children by reference, so a result shares every unchanged
+subterm with its input.
+
+- **Equality is decided, not assumed.** The executed equality follows the
+  official kernel: pointer equality first, then the computed hashes, then
+  structural descent (`IxC/Kernel/Expr.lean`). Every branch returns
+  `Decidable (a = b)`. Pointer equality is a fast path for equal terms and a
+  hash mismatch one for unequal terms; an equal hash decides nothing.
+- **The equality memo is verified.** An entry is the pair of objects a
+  completed descent proved equal, with the proof. A probe finds a
+  candidate by the packed address pair (`beqKey`) and then checks the
+  candidate by identity, so a key collision between distinct pairs costs an
+  entry, never an answer.
+- **Memo keys are terms.** The scope and definedness walks key their memos on
+  `Expr` itself (`Std.HashMap Expr α`: hashing off the cached field,
+  pointer-first equality); the substitution walks key theirs by address
+  (`IxC/Kernel/Cached/ExprOpsC.lean`).
+- **Trust.** That the stored word agrees with the function defining it is
+  the code generator's guarantee, not a theorem of this repository:
+  `@[computed_field]` is implemented with `implemented_by`. It is the one
+  entry of the trust census in `IxC/Kernel/Cached/ExprNodes.lean`.
+
+Before IxC, this layer belonged to the retired Rust kernel: per-node blake3
+hashes at first, then intern-assigned `u64` uids from a process-global
+counter, with a hash-consing intern table keyed by shallow structural keys
+([retired Rust](retired-rust.md)).
 
 ## The boundary rule
 
 > Anything that crosses the kernel boundary — claims, public values,
 > proof-store entries, assumption sets — is identified by Ixon
-> `Address`. Kernel uids must never escape into a serialized artifact.
-
-This held before the change (nothing consumed the old expr hashes
-outside the kernel) and is now structurally enforced by the type split:
-`Address` (32-byte content hash) vs `Addr = u64` (kernel uid) vs
-`CtxAddr` (blake3 digests for local-context cache keys, fed by uids,
-also internal-only).
-
-## Adversarial model: why uid identity cannot be cache-poisoned
-
-The natural worry about replacing blake3 with `u64` identity is hash
-collision: *if two subterms had the same internal hash, a def-eq/whnf
-cache hit could return a result for the wrong term.* The design avoids
-this not by making collisions unlikely but by making them impossible —
-**uids are assigned, not computed**:
-
-- A uid comes from a process-global sequential counter
-  (`expr.rs::fresh_uid`), never from hashing input content. There is no
-  function from term content to uid for an adversary to find collisions
-  in — and no birthday bound either: uids are handed out once each, not
-  sampled from a space two terms could land in. Two `KExpr` values share
-  a uid only if they are clones of one construction event or the
-  canonical node the intern table returned for the same shallow key.
-  `fresh_uid` aborts on counter exhaustion (which would require >2^67
-  guest cycles) rather than wrap, and the only constructors that accept
-  a caller-supplied uid (`*_mdata_with_addr`) are private to `expr.rs`,
-  so no code outside the module can copy one node's uid into a
-  different structure.
-- **Between shards** (separate guest processes), uid collisions are
-  certain — every process counts from 1 — and harmless by design: a uid
-  is meaningless outside its process. Nothing serializes a uid (the
-  committed publics are blake3 addresses and Merkle roots; intern tables
-  and caches die with the process; manifests and the proof store carry
-  `Address`es only), so there is no channel through which shard A's
-  uid 42 could meet shard B's. All cross-shard identity — claims,
-  assumption resolution, proof reuse — lives in the Ixon `Address`
-  layer. Any future feature that wants to persist or ship a
-  reduction/intern cache MUST re-key it by content (e.g. Ixon
-  serialization hashes) first; see the boundary rule above.
-- The intern table is keyed by [`ExprKey`]/[`UnivKey`] — exact
-  structural keys compared by full `Eq` (variant tag, child uids,
-  complete 32-byte payload addresses; never truncated, never a digest).
-  `FxHashMap` bucketing uses a weak hash, but a bucket collision only
-  causes an extra key comparison, not a wrong hit. Children in a key are
-  canonical by induction, so key equality ⇔ structural equality. Debug
-  builds assert structural equality on every intern hit.
-- Reduction caches key on `(uid, CtxAddr)`; a hit requires uid equality,
-  hence structural equality. `CtxAddr` (local-context digests) remains
-  blake3 — collision-resistant — fed with uid bytes.
-- An adversarial env cannot choose uids at all: deserialization never
-  produces a uid; every node built from input takes the next counter
-  value. Compared to the old scheme — where cache keys were blake3 over
-  attacker-chosen content, so an attacker could at least grind contents
-  to flood `FxHashMap` buckets of their choosing — sequential uids give
-  the adversary strictly *less* influence over key distribution.
-
-The one place adversarial content does enter identity is **literals**:
-`ExprKey::Nat/Str` and structural equality key on the blob `Address`
-(mirroring the old content hash, which also hashed only the address).
-That is sound only if an address is bound to its bytes — so all three
-env deserializers verify `Address::hash(bytes)` for every blob at load
-(the constants' equivalent check runs lazily at first materialization),
-and the literal arms of structural equality compare values as well as
-addresses as defense in depth. Residual exposure is limited to DoS
-(bucket flooding of maps keyed by attacker-chosen `Address`es slows the
-prover, which is spending its own cycles), not soundness.
+> `Address`. The checker's node hashes and object addresses must never
+> escape into a serialized artifact.
+
+## Adversarial model
+
+The natural worry about non-cryptographic internal identity is collision:
+*if two subterms had the same internal hash, a def-eq or WHNF cache hit
+could return a result for the wrong term.* Here a collision costs time,
+not soundness:
+
+- An equal hash never decides equality: the descent continues
+  structurally, so a collision makes a comparison slower, not wrong.
+- Hash maps keyed by `Expr` compare keys with that decided equality, so a
+  bucket collision causes an extra comparison, not a wrong hit.
+- The equality memo checks every candidate by identity before using it.
+- Object addresses are not content: an input cannot choose them, and
+  nothing serializes them.
+
+An adversarial environment can choose term contents, and so can grind
+contents to collide hashes and flood buckets. That slows the checker,
+which is spending its own cycles; it does not change an answer.
 
 ## Future: sub-constant commitments
 
 If a feature ever needs cryptographic identity for **subterms** (e.g.
 Merkle inclusion of a specific expression inside a constant's body,
-rather than inclusion of a constant in a claim), expression-level
-content hashes no longer exist precomputed. The right move is to compute
-them at that boundary: a one-time egress pass over the relevant term —
-either the old `(tag ‖ child hashes)` Merkle-DAG scheme or blake3 over
-the Ixon serialization of the subterm. That is cheap where it is needed
-and keeps the per-node cost out of the prover's hottest loop. No current
-artifact (claims, aggregation, reuse, inclusion proofs at constant
-granularity) needs it.

+with the canonical sharing construction, on a work-stealing scheduler that
+streamed the `.ixe` to disk. The crate also held the Rust decompiler and the
+kernel's egress to Lean declarations.
+
+- **Relation to Lean.** A pure-Lean compiler existed first; the Rust compiler
+  became the fast production path, and the current Lean driver was then
+  ported back from it. At the archive commit, `Ix/CompileDriver.lean` opens
+  with "Port of the production scheduler semantics of
+  `crates/compile/src/compile/env.rs` … and the per-block dispatch of
+  `compile_const`", replacing work-stealing threads with a deterministic fold
+  over waves.
+- **Trust.** Opt-in (`ix compile --rust`) and outside `CompileCorrect`: it ran
+  none of the compile report's checks. It was held to the Lean compiler only
+  by byte equality (suites `compile`, `cert-compile-parity-initstd`,
+  `initstd-reference` through `compile-lean --rust-check`, and the merge-queue
+  `--ignored compile` over the test environment).
+- **Performance reference.** It remains the speed to aim at. In the
+  historical runs of [BENCHMARKS.md](../BENCHMARKS.md) ("Compilation", an
+  older pipeline), it compiled, serialized and wrote Mathlib in 63.6 s, where
+  the Lean compile phase took 723.0 s; Init+Std took 4.70 s against 39.9 s.
+  At the sharing cutover the Lean compile phase took 556.658 s on Mathlib's

+
+- **Trust.** Uncertified, and never a fallback for the certified entry.
+  IxC is a separate design, derived from con-leche's verified checker, not a
+  port of this kernel. Its tests compared verdicts: the tutorial and
+  check-env suites, and on Init+Std the `initstd-reference` fixture, where it

+  `tiered.rs` calls itself "a rule-for-rule port of the Lean
+  `Ix/Sharing/Exact/Tiered.lean`". Lean is the proved reference; the port was
+  unproved.
+- **Testing.** The Lean/Rust suite `exact-sharing-ffi` compared bytes on
+  fixtures, generated inputs and the compiler route, and over whole `.ixe`
+  corpora; Init, Init+Std, Mathlib and the merge-queue environment compiled
+  identically ([sharing-minimum §12.10, §14.4](sharing-minimum.md)). Two test
+  pieces existed only in Rust: the MSS reference encoding (`mss.rs`) and the
+  limit-grammar list `LIMIT_SPEC_PARITY`, which Lean keeps as
+  `limitSpecParity`.
+- **Speed.** On one captured input the port took 25.50 s where Lean took

-so closing the gap needs a change of the specification and its proofs (follow-up).

-**Review fixes.** Rust no longer applies its `candidates` limit (2^16, meant for the width-state
-oracle) to the canonical path; in both languages the candidate count is recorded, not limited
-(Rust regression test: 70,000 distinct references used twice). `knapsack_cells` (2^28) is about
-27 times the largest knapsack on Init and Mathlib. The limits override is parsed by one grammar
-in both languages (digits only; 35 shared specifications) and read once per run. Rust's phase
-1 computes in 128-bit integers and, where a value leaves that range, again in exact integers
-(`uniform/arith.rs`; the result is the same wherever the 128-bit run succeeds), so it agrees with
-Lean's `Nat` on inputs such as the chain `e(i+1) = App(e(i), e(i))` at depth 127 or more, whose
-unshared length exceeds `2^127` (the Lean/Rust sharing suite compares four such towers byte for
-byte). The layout length equals the serialized length by theorem (§12.13), and the metadata
-table check is linear in both languages.
+**Fast implementations.** The specifications are the proved reference. Fast twins
+(`Exact.Phase3`, `Exact.Reexpand`, `Exact.UniformSearchLocal`, `Exact.TierFast`,
+`Exact.PinnedDeps`, `Exact.PinnedFast`, `Exact.KnapsackFast`, `Exact.TieredFast`; the module map
+of `Ix/Sharing/Exact.lean`) are attached to the specifications by unconditional `@[csimp]`
+equalities, which are audit roots; `IxSharingVerify/Audit/CompiledCode.lean` fails the build if
+a csimp theorem on the compiler's import path is not a root, and the sorry frontier covers
+`Ix.Sharing`. What the compiled code does differently:
+
+- `Exact.TieredFast` computes the width-independent tables (`Prep.ofDag`, the graph facts, the
+  DAG checks, the candidate count) once per constant instead of once per width and phase, and
+  on a DAG of at least 1,024 terms (`tieredParMin`) runs the three widths as parallel tasks,
+  combined in width order (`tieredCandidates_eq`: the same value and the same error).
+- The table-count knapsack works on ranks (`Exact.KnapsackFast`).
+- Phase 3 evaluates the whole table once when the order is closed under stored descendants
+  (`onePassOrder`; every order of Init and Mathlib is), and once per prefix otherwise
+  (`materializeTableOnePass` falls back to `materializeTable`). The per-prefix path is
+  reachable: in `Tests/Ix/SharingTiered.lean` an App spine of 1,288 nodes ending in a stored
+  term sends one candidate down it, and a spine of 1,287 nodes sends none.
+
+**Checks and metering.** Every candidate, not only the returned one, runs all three phases
+under the same limits and with the same checks. In phase 3 (`rematerialize`) these are the
+layout length against the evaluated length and against phase 1, the re-expansion to the stored
+terms and the input's root IDs, and the wire domain (§12.13). An error at any width fails the
+call with the error of the lowest failing width. Metering follows the specification, not the
+path the compiled code takes: `materializeTableOnePass` equals `materializeTable` on every
+input, errors and `materializeWork` charges included (`materializeTableOnePass_eq`), so a
+limit has the same outcome on either path. `materialize_work` (2^56) budgets the per-prefix
+count, about `2·k·N` for `k` entries over `N` terms. The serialized length is not measured at
+run time: it equals the layout length by theorem (§12.13).
+
+**Speed at the time.** The merge-queue partition `lake test -- --ignored compile`, which then
+compiled every constant of the test environment with the Lean and the Rust compiler, took 11:51
+against 15:30 before the route switch; its Lean step took 238 s against 177 s. The Lean
+construction was 8–15× slower than the Rust port single-threaded (about 8–12× on Lean 4.34.0,
+re-measured on Init samples of the same sizes: 7.9×, 10.5× and 12.1×), short of the 2–4×
+target, because the specification's cost model evaluates a component's whole closure where the
+port evaluated its area. The area search (`Exact.AreaSearch`) and, for the K16 family, the
+guarded area evaluator (§14.3) later brought area evaluation to Lean as proved twins.
+
+**Review fixes.** The candidate count is recorded, not limited, on the canonical path: the
+`candidates` limit (2^16) belonged to the width-state oracle, and the Rust port had applied it
+to the canonical path until a regression test of 70,000 distinct references used twice caught
+it. `knapsack_cells` (2^28) is about 27 times the largest knapsack on Init and Mathlib. A limits
+override has one grammar (`Limits.withOverrides`: digits, `2^k` or `max`; the 35 specifications
+of `limitSpecParity`, `Tests/Ix/SharingExact.lean`). Lean computes lengths in `Nat`, so a long
+unshared length is never a refusal; the chain `e(i+1) = App(e(i), e(i))` at depth 127 or more,
+whose unshared length exceeds `2^127`, is where the port needed exact integers past 128 bits.
+The layout length equals the serialized length by theorem (§12.13), and the metadata table

+growing faster than linearly on some shapes. These shapes were timed on the retired Rust
+port, which ran the same rule; what is known of Lean on each is stated with it:
+
+- **A long `Lam` telescope.** The port's telescope scan walked the whole spine below each
+  telescope node, in phase-1 materialization and phase-3 costs: about 1 s at 10,000 binders,
+  4 s at 20,000 and 105 s at 100,000. Lean's evaluator follows links to the next available
+  spine node and is linear on this shape when no spine node is stored; its base evaluations
+  and expression builders still scan up to a spine length per term (above). The work is
+  charged.
+- **A long argument chain.** The port collected each term's distinct parents with a linear
+  search, quadratic in a chain's parents (1.27 s for 200,000 arguments, 7.19 s for 400,000),
+  until it compared only with the last parent recorded, since parents arrive in increasing
+  order (0.29 s and 0.60 s). Lean has not been timed on this shape.
+- **Many repeated references.** A probe with many repeated references grew quadratically in
+  the port (80 ms at 1,000 repetitions, 357 ms at 2,000). The cause was not isolated; the
+  suspect is the representative lists of the uncertain-component pass, which grow the same
+  way in Lean (above).
 
 Of the internal guards the proofs make unreachable, the family route no longer runs three:
 the component partition check (`componentsChecked`, quadratic in the uncertain terms), the
 negative-model check, and the check that the retained best row sits at its own count. Each
 removal is byte-neutral and does no metered work, so refusals under every budget are
 unchanged; the proofs take the partition from `stage_componentsChecked` and the model's sign
