Summary

XL-0N (node://adhoc-aec65f93-b00). v2.std.nat.Nat = Zero | Succ stays the structural Peano coproduct; no Nat -> i64 realization row is added. Instead the compiler gains its first generic authorities for the two things the emitted v2 closure was getting wrong by spelling:

  1. Literal elaboration (std.literal_elaboration, dag/std/literal_elaboration.dag): a kernel literal at a typed boundary whose exact destination DeclarationRef declares a homomorphism from the kernel value is replaced, in the typed tree, by a new core carrier ExprElaboratedLiteral { value, elaboration } whose child is the literal's image under that homomorphism (Succ { prev: … Zero } for the Peano unfolding), typed as the destination. v1.compiler.infer applies it at every position that already supplies an expected type (call argument, declared return, record field, data initializer, annotated let, list element, map value, block tail) and at the other operand of a binary operator when one side is a literal. Emission renders the image as ordinary constructors and never re-decides from spelling, imports, or rustc expectations. Outcomes: DirectLiteral | ViaHomomorphism | LiteralElaborationRefused { HomomorphismDuplicated }. The interpreter evaluates the image (its numeric grounding folds Succ/Zero exactly as authored ones) — 2 hand-Rust arms in v1_interpreter.rs, the only hand-Rust in this change.
  2. Operator realization (std.operator_realization, dag/std/operator_realization.dag): emit_typed_bin_op decides by the operand's exact declaration — HostOperator when the declaration realizes natively on Rust (v1.compiler.coercion declaration_realizes_natively_on_rust: exact binding, then the identity-gated checkpoint), StructuralEquality (the emitted enum's derived PartialEq), StructuralComparison (a call to the declared comparison tested against std.algebra.Ordering), or a typed compile_error! refusal for infix arithmetic on a structural operand.

Rows live in gunbc.structural_realization_bindings: KernelIntLiteral -> v2.std.nat.Nat via Zero/Succ/prev; KernelBoolLiteral -> v2.std.logic.Bool via True/False (BooleanUnfold, the manager's Bool addition — the interpreter realizes Bool natively and evaluates an elaborated literal as its kernel value, so the Bool image is evidenced on the emitted path only); v2.std.nat.Nat ordering via nat_compare. where-refined declarations (NonEmptyStr, Char, VersionIdentity) resolve to the parser's one-child Conj refinement wrapper, so the operand decision hops is_where_refinement_type → base (resolved through the env) — the type renderer's own route (render_rust_alias_rhs_type) — before judging; measured under regen, where the earlier alias-item hop could never fire. Every BinOp match in std.operator_realization is total over the 14 closed variants (no non-fold-residue rows). XL-0T adds its FreeMonoid unfolding arm and one row; nothing per-destination exists in inference or emission.

The census subject is repaired at its source too: v2.std.nat gains a structural nat_compare (the old body was if a == b … if a < b — the host < rustc refused), nat_sub (typed underflow), nat_div_rem (NatDivisionByZero arm) and nat_div_rem_by_succ (the zero divisor has no constructor). v2.std.integer's decimal conversion is rewritten onto them, with one digit-glyph table shared by the Peano and machine-integer renderers; the two Int-valued callers that passed an Int into the Nat renderer (native_agreement, realization_sweep — E0308 sites) now call a real Int formatter.

floor_expected_red chunk 14 (w_kernel_numeric_at_the_peano_nat_is_refused) is retired by its own stated trigger ("the expected-type-directed literal introduction judgment is NOT built"); the witness now asserts the ruled admission through the homomorphism and stays enrolled as a control (DESIGN §4b(4)).

Identity at the boundary (measured; read once at inference, carried on the typed tree)

v2.std.nat.Nat is recursive (Succ { prev: Nat }), and the resolver leaves a recursive type reference in place (resolve_node leaf arm, is_recursive_type_for → resolved: n, no inferred). The identity lookup matched the reference-site span against the declaration span and answered Absent, so every Peano boundary fell to its "identity unavailable" arm while v2.std.logic.Bool (not recursive) worked on the same compiler. Fix (v1.compiler.infer_env type_reference_declaration): resolve the reference through its scoped env binding (lookup_type_for) before span-matching. That binding is live at inference and gone at emission (only the module env survives), which is why the literal rows passed and the operator rows kept the host token: a by-name fallback tried for the emitter was refuted by construction — it answered the pool-precedence homonym std.nat.Nat (native, i64) for a module importing v2.std.nat.Nat, and the span match confirmed that homonym exactly. So the operand's declaration is now read once, at inference, and stamped on the typed tree as ExprBinOp.operand: OperandDeclaration { declaration, decl_file } (after hopping a where-refinement to its base); emit_typed_bin_op consumes it and never re-reads identity. The by-name arm is deleted.

An operand whose type node names no declaration (inference-synthesized field-access / method-return nodes: no span, no file) is OperandIdentityUnavailable { facts } and decides by operator class, never by a default: ==/!=/&&/||/?? are the host token by construction (structural and host equality are one token on the target — the emitted enum derives PartialEq), ordering and arithmetic refuse carrying the shape facts. The pre-lane Unavailable => HostOperator arm was the absorbing fallback (DESIGN §5) that hid this lane's own defect; the refusal census that replaced it measured the whole v1 closure at 50 sites / 139 refusals, every one under ==/!=. Kernel-minted types (<kernel:…>), generic type parameters and host containers are their own named arm (HostRealizedOperand).

Partition layout: std.literal_elaboration / std.operator_realization registered in the std-core partition and gunbc.structural_realization_bindings in the v1-infer binding unit (v2.workflow.rust_crate_partition), with module-dag edges; the generated artifact gunbc.stage0_crate_partition_generated regenerated via generated_artifact_gate main_wet and the partition crates re-rendered by claim_executor --emit-partition-crates --write (never hand-edited).

A second, separate defect surfaced on the way and is fixed at its single site: a record literal nested in field position (Succ { prev: Succ { … } }) was rendered with the outer type's name as its head (Nat::Nat) because emit_field_value_with_context handed the raw resolved type to the constructor namer while the top-level path expanded it first (expand_type_for_field_access); the nested site now expands the same way.

Falsifiers (required seed prefixes)

  • v2.test.claim.self_host.peano_nat_structural_realization_test — 26 rows: nontrivial Succ values compare/subtract/divide/convert correctly; divide-by-zero is typed; the generic decisions by row and identity, including removing the row returns the literal to DirectLiteral (the E0308 shape) and duplicated rows refuse; an operand without a readable declaration refuses under <// and is host under ==; the Bool row is found by exact destination, Direct once removed, and Direct at the native std.types.Bool (no variant of Bool is matched by name in interpreter-run rows).
  • test.claim.self_host_peano_literal_operator_realization_witness_test — emitted bytes through the production emitter: literal at argument/return/operand boundary emits its Zero/Succ image (forbidden tokens are the pre-lane rendering), </<= call nat_compare against Ordering, infix / on Nat refuses in the bytes, a kernel true/false at a v2.std.logic.Bool boundary emits Bool::True/Bool::False while the native std.types.Bool keeps the keyword, and three host controls (native Int, and std.nat.Nat — same spelling, different declaration — keep the host token and the bare digit).

Test plan

  • claim_batch … --entry src/v2/test/claim/self_host/peano_nat_structural_realization_test.dag --functions <all 26> in the interpreter on the fixed-point binary: 26/26 PASS (regen20).

  • claim_batch … --entry dag/test/claim/self_host_peano_literal_operator_realization_witness_test.dag --functions <all 12> through the production emitter on the fixed-point binary: 12/12 PASS (regen20; was 9/12 before the typed-tree operand carrier, 6/12 before the nested-head fix + layout).

  • gunbc compile (prebuilt seed) over the model modules, v1.compiler.coercion, v1.compiler.infer_env and the rewritten v2.std.integer closure: 0 blocking diagnostics.

  • Seed regen (BuildBuddy, bootstrapped from the committed mirrors, rounds to first_generation_equal=true): every head on this branch since 370f5fa converged at round 2; the mirrors are committed at each step. CI on earlier commits was red by construction (pre-lane mirror, then mirror drift between a .dag change and its regen round).

  • Whole-closure census, src/v2/compiler/00_compile.dag emitted through the production pipeline (gunbc compile -> cssl_assemble -> cargo build --lib --message-format=json, BuildBuddy 20 GB runner; the instrument's 16 KiB stderr capture truncates this closure, so the rows are read from the JSON messages) -- identity diff, row = (rustc code, emitted file, message), lane head 2177446 vs main head 0a6d177: main 57 rows -> lane 52 rows; 5 rows gone, 0 rows new, and no row mentioning Nat remains. Gone: E0369 v2_std_nat.rs binary operation < … Rc<v2_std_nat::Nat>, E0369 v2_std_integer.rs binary operation < …, E0369 v2_std_integer.rs cannot divide Rc<v2_std_nat::Nat> by {integer}, and two E0308 v2_std_subject_evidence.rs rows. The remaining 52 are other lanes' classes (E0004 Edge exhaustiveness, E0223, E0277, the Rc<i64> wraps of the agreed follow-up). The E0308 literal-at-Nat sites share the generic mismatched types message with unrelated sites, so at this row grain they are witnessed by the per-file rows above and by the emitted-path battery rather than as distinct identities.

    A CORRECTION TO AN EARLIER RUN OF THIS SAME MEASUREMENT, recorded rather than quietly restated. The first pass keyed rows on ^E\d{4} and so DROPPED every rustc error carrying no code -- which is exactly what a compile_error! refusal is, the shape this lane introduces. Under it the head reported 52 rows against a TOTAL 53, and the discrepancy was the whole finding: the hidden row was a refusal THIS lane produced at v2/compiler/02_parse.dag parse_current_position (t.start + 1, where t binds the value of a generic ListHeadResult<T> and the field-access type node inference builds carries no authored name). So "0 new" was true only of the codes the filter could see. The arm is fixed at its cause -- an operand type node with NO authored name is not a reference to a declaration, and is HostRealizedOperand { UnnamedSynthesizedType } -- and the numbers above are from the corrected instrument, where mine 52 = TOTAL 52 closes the same gap by identity rather than by assertion.

  • Required floor: new witnesses planned/passed by identity in required_floor_disposition.tsv.

…nt, and a primitive with no realization refuses instead of inventing one

Two roots behind 175 of the 260 rustc errors on the emitted v2 compiler
closure (issue #9664, milestones 1 and 2):

- 102 x E0425: the four DeclaredCallableIdentity constructions in
  v1.compiler.infer_lookup took decl_name from the AUTHORED spelling, so a
  qualified call carried the whole dotted path as the declaration name and
  emission rendered crate::v2_std_grammar::v2.std.grammar.f(..).

- 73 x E0425: v2.std.algebra length is a ModeledProjection of the `length`
  primitive and rt_function_registry has no `length` row, so emission took
  rust_runtime_bridge_name's identity arm and wrote v1_rt::length -- a symbol
  the seed does not define. A primitive's identity and its per-target
  realization are two facts; CallTargetIdentity carried only the first, so
  every emitter had to ASSUME a bridge exists.

RuntimePrimitiveCall now carries projected_from, the declaration the roster
projected it from, and emit_rust routes to the bridge only when its own
registry holds the primitive, falls back to the declaration otherwise, and
refuses when neither exists. DeclaredCallableIdentity moves to v1.std.core so
the target type can carry it without forking the pair.

…ot checked

tier0 method resolution resolves an ordinary fn-typed RECORD FIELD through
lookup_field_in_product, so `algebra.step(..)` arrives as AlgebraMethodSemantics
carrying the field node as its method_def. The fallback at the end of that arm
hardcoded runtime_bridge: true, which emitted `v1_rt::step` -- and made
emit_rust_generic_method_call's own callable-field arm, guarded on
runtime_bridge == false, unreachable for the exact receiver it was written for.
65 E0425s on the emitted v2 compiler closure (member, apply, is_empty, step,
init, allocate_literal, ...) were that one literal.

It now passes the realization question keyed on the same registry as the
plain-call seam, so a real bridge method still lowers to a bridge, a callable
field lowers as a field, and a name that is neither reaches the existing loud
refusal rather than a fabricated symbol.

…y is a self-call, so falling back to it would emit a nonterminating function

The declaration fallback is sound only where the declaration's body is real
code. HostRealizedSeam means the body IS a self-call, so emitting it compiles
and then loops forever -- silent wrongness, strictly worse than the unresolved
symbol it would have replaced. A seam whose target has no realization has no
honest lowering, so it carries nothing and reaches emission's refusal.

…lared to be host seams

v2.std.compilers.lexing symbol_lexeme and symbol_intern_lexeme have self-call
bodies -- the HostRealizedSeam shape exactly -- and the interpreter has carried
real arms for both (v4_bridge.symbol_lexeme, v4_bridge.symbol_intern_lexeme).
With no projection roster row the resolver saw ordinary declarations, so Rust
emission emitted the declaration, and

    pub fn symbol_lexeme(sym: String) -> String { symbol_lexeme(sym) }

COMPILES. The emitted closure carried two functions that type-check, pass every
gate we own, and diverge from the interpreter by not terminating. Unlike the
sibling seams (decl_facts and friends, which at least refuse loudly as
unresolved v1_rt symbols) nothing anywhere reported this one -- it is absent
from the E0425 census precisely because it is silent.

extdeps.languages.rust.types already declares Symbol's target type as String,
so on this target both bridges are the identity. That is a realization of the
declared row, not a second opinion about it.

Residue named, not closed: a self-call body is a DECIDABLE structural marker of
a host seam, so the compiler could refuse an unrealized one rather than emit it.
It does not yet; that check is the class's next-rung trigger.

…, with boundary controls

Six rows over the three emitter defects plus the two symbol bridges. Each
class's positive and negative assertion differ only in the fact the repair
added, so no single edit satisfies both directions, and each repair carries a
boundary control that would go red had it over-reached the other way (empty_map
for the registry gate, a registered bridge method for the class-B gate).

The symbol-bridge row is deliberately not an error-count assertion: that class
COMPILED throughout the defect and diverged by not terminating, so a row
asserting 'no error' would have been green the whole time.

…never reaches the seam under repair

count is answered by rust_simple_method_specs before the algebra fallback, so
the row would have gone red while executing none of the code the repair
touched. trim is in rt_function_registry and has no template, so it is one of
the few names that actually reaches that fallback.

…mitting compiling recursion

A whole-body self-call is the decidable structural marker of a host seam. In the
interpreter the shape is safe -- reaching it recurses to the evaluation-budget
refusal -- but emitted to Rust the same shape COMPILES and returns to no caller.
Nothing reported it: not the module index, not the compile-clean gate, not cargo
check. That is why the two symbol bridges were invisible until someone read the
emitted bytes.

emit_fn_def now asks the realization registry -- the same authority the call
sites ask, so the two cannot drift -- and suppresses the declaration when the
seam is realized, refuses with a located message when it is not. Suppression
rather than delegation is deliberate: a forwarding body would make this seam
reconstruct signatures in target types, which is the cementing the existing
suppressed-seam precedent avoids, and a realized primitive's calls all route to
the bridge anyway.

The predicate is whole-body identity, not 'contains a self-call'. Ordinary
recursion has a match, an if or a let between the head and the call, so it never
matches; expr_has_self_call walks children and would have refused most of the
compiler. Both directions carry a fixture.

…, not the declaration name

Measured, not predicted: the wall refused six seams in the emitted closure and
one of them -- v2.std.collection empty_map_primitive_delegate -- is realized.
Its roster row names the empty_map primitive, whose bridge is rc_empty_map, but
rt_function_registry holds 'empty_map' and the wall looked up
'empty_map_primitive_delegate'. A declaration's name and the primitive it
realizes are two facts; the roster is the authority that joins them, and the
declaration name is only the fallback for a seam nobody has rostered.

…ession created 10 dangling imports

Measured on the emitted closure with the wall finally in the mirror: removing a
realized seam's item left 10 unresolved imports (E0432) for symbol_lexeme,
symbol_intern_lexeme and resolve_type_node. Other modules import these
declarations; the suppression created that breakage rather than finding it.

And the reasoning that made suppression look safe is what makes it unnecessary.
A realized seam's body IS a call to itself, and resolution already routes that
call through the roster to the bridge -- so ordinary emission writes
v1_rt::symbol_lexeme(sym) as the body without help. The wall's whole job is the
UNREALIZED arm.

…: rustc's denominator is larger than the demand denominator

compile_error! fails the WHOLE crate, and that form silently assumes every seam
it refuses is one somebody calls. It is not. rustc type-checks the entire
emitted crate including declarations imported but never invoked, so the refusal
denominator is strictly larger than the entry-reachable execution closure --
five unreachable seams took the crate down.

The refusal is now a panic body with the declaration's real signature: dependent
modules resolve, the crate compiles, and only an actual invocation fails loudly.
That moves the refusal from the crate to the one declaration that earned it, and
leaves reachability to a separate instrument. An entry-rooted pruner can replace
the body later without revisiting this.

…his change

DETERMINISM DENOMINATOR (9 reach_witness rows red, including
determinism_denominator_is_closed_on_declared_primitives, whose entire job is to
notice this). v2.lens.determinism closes its denominator over
primitive_declared_definitions, so adding two canonical names without traversal
facts made the closure false. Both bridges are scalar -- symbol_lexeme maps one
Symbol to its text and symbol_intern_lexeme is its inverse -- so there is no
collection to walk and OrderFreeResult is the honest arm. HostUnspecifiedOrder
would claim a real traversal whose order the host does not pin, fabricating a
leak the primitive cannot have.

NAMESPACE WAVE ADMISSION (6 unadjudicated deltas). Four are TargetChanged for
DeclaredCallableIdentity moving v1.compiler.infer_sigs -> v1.std.core, which is
what lets CallTargetIdentity carry the declaration a runtime target was
projected from. infer_sigs imports v1.std.core, so the type could not stay put
without a cycle. Four enumerated rows, one per binding site; the two membership
deltas auto-admit as ExplicitlyEvaluatedZeroDelta. Dissolve-on: this PR merging,
by the same trigger the three prior shrinks record.

…er than the corpus

The row FAILED while the mechanism was green. The probe used the qualified
spelling without importing v2.std.collection, which resolves against the real
4261-module corpus but not against compile_dag_rust_emit_check's 2973-module
witness pool. Measured both ways: emitted against the corpus the same probe
produces crate::v2_std_collection::map_get(m.clone(), "key".to_string()),
exactly what the row asserts.

The import restores module presence and does not answer the call -- decl_name
comes from the authored spelling at the call site regardless of imports -- so
the negative assertion still discriminates. Falsifier 2 is what proves that
rather than argues it.

…n it never had

Before the class-B change, xs |> is_empty emitted v1_rt::is_empty, a symbol the
seed does not define: 5 x E0425. After it, the same 5 sites became typed
refusals -- correct in kind, still 5 errors. The class-B repair made the gap
visible; it did not close it.

is_empty is an algebra template over FreeMonoid whose Rust realization is
Vec::is_empty, exactly as count's is Vec::len, so the fix is one row in
rust_simple_method_specs beside count. Nothing in 05_emit_rust learns a new
name: realization is a target fact and lives in the target's registry.

…s B survived one layer up

The requested is_empty negative control found a live hole rather than confirming
a safe one. Both rust_method_templates lookups are keyed on the bare method
spelling with no receiver check, so a fn-typed record field named is_empty was
captured by the target template and emitted as recv.is_empty() instead of
(recv.is_empty)(..). The class-B repair fixed the algebra FALLBACK and left the
two tables sitting in front of it.

The hole is not new and is not specific to is_empty: count, first, join, split,
take, skip, last, chars and enumerate have carried it for as long as they have
had templates. Adding is_empty made it urgent by putting the spelling most
likely to name a predicate field in front of that table.

One helper, consulted at the top of both arms before every name-keyed special
case, so the two cannot drift. Two controls: the new spelling and a pre-existing
one.

v1.compiler.infer_sigs used to DECLARE DeclaredCallableIdentity, so its own two
construction sites resolved locally and produced no delta. Now that the
declaration lives in v1.std.core and infer_sigs imports it, those sites rebind
exactly like the consumers in infer_lookup. An enumeration error on my part, not
a second transition: same subject, same trigger, same dissolve.

Floor is now green on this branch (passed=2754 failed=0) -- the OrderFreeResult
traversal facts closed all nine determinism rows.

…domain, not the receiver's: 202 refusals on the first compile of the converged seed

rust_receiver_has_callable_method_field asked rust_record_field_needs_fn_rc,
which sweeps rust_struct_field_lookup_candidates -- and that list deliberately
widens a receiver's name to its container template algebra. An algebra declares
its operations as arrow-typed members, so under that widening every Map receiver
"has a callable field" named map_keys, map_values, lookup or get, and the tier
captured the very bridge calls it sits in front of.

Measured at the first compile of the round-3 converged mirror: 202 rustc
refusals, one class -- 164 E0609 (no field `map_keys` on
Rc<im::HashMap<String, Rc<ItemInfo>>> and friends), 48 E0282, 4 E0615 on `get`.
It is the same defect the tier was built to close, one level up: a name-keyed
lookup consuming an identity domain that is not its own.

The predicate now consults only the receiver's own declared record.
w_map_receiver_operation_is_not_read_as_a_callable_field is the discriminating
red: restore the candidate sweep and its must_not_contain clause fires.

…e variant arm; the qualified route synthesizes use-lines only for types the emitted source names

Four regressions the 0773184 fixed point put on the closure, each with its discriminating row:

- E0603 x16: the qualified-type route synthesized `pub use crate::v2_std_nat::Succ;` for every
  `v2.std.nat.Succ { prev: .. }` record literal. A qualified name reaches the surface walk in the
  same dotted spelling whether it is a type or a variant head; the route now asks the registry
  whether the leaf is a TYPE declared in the named qualifier, records each decision as a census
  row, and considers only leaves the emitted source actually names (it had also synthesized an
  unused `DeclarationRef` import from a variant payload).
  w_qualified_variant_head_earns_no_type_use_line.

- `Outcome<compile_error!("UNRESOLVED_CompilerError")>` x3 and `Rc<Medium>` E0107: two cuts had
  each introduced a second per-position renderer for arrow types beside the one fn parameters use.
  An arrow's return is not a different kind of type from its parameter: both positions now render
  through render_rust_fn_sig_type, and render_rust_type_with_applied_binding -- which rebuilt its
  EmitGraphInfo with an empty generic scope, so a fn-scope `C` rendered `_` (E0121) -- carries the
  fn's generic names through that hop. The measured gate over the second renderer is deleted.
  w_generic_arrow_return_renders_the_fn_scope_generic; w_arrow_return_type_keeps_its_applied_binding
  (its fixture was an invalid program: Accepted lacked `diagnostics`).

- v2.std.determinism E0425 x2: traced to the bare-name disposition, not the qualified route --
  `Determinism` is a type in std.determinism and a variant of v2.lens.registry LensIdV0, and
  is_known_variant is corpus-wide by spelling, so a TYPE-position reference was delegated to an enum
  it never named. A name in one of the module's type positions never takes the variant arm.
  a_known_variant_spelling_in_a_type_position_takes_the_registry_arm (red by construction on the
  old arm); the harness row is a positive control and says so, because the witness harness refuses
  any pool carrying the colliding variant with NoSuchVariable.

Verified on a test binary built from the self-emitted emitter (not a regeneration): witnesses
23/24 -> 24/24 after the harness row was reshaped; closure instrument 2799 -> 2779. The regeneration
that binds these to the mirror follows as its own commit after the freeze merge.

binop_is_equality hand-matched the BinOp coproduct to answer a question no
caller asked; binop_is_ordering wrapped ordering_test_for in a Bool and had
no caller either. Both were this lane's additions (f38fdc9, db40481) with
zero consumers corpus-wide, so they are redundant work by DESIGN section 2 and
the substrate keeps one canonical typed query, ordering_test_for, which
remains consumed at operator_realization_for.

…row, prose leaves the data plane (review 57758)

Three of the four findings, verified against the tree first:

- src/v2/std/nat.dag carried a String data row of commentary. Converted to a
  module-scope // annotation on nat_max, which is the DESIGN section 4c
  quarantine boundary; the row predates this lane (#9238) but the file is this
  lane's to fix.
- The same note narrated the two-Nat fork without scheduling its end. The fork
  is now gunbc.guarantee_rung_drop two_nat_authorities_stall, with ceiling
  StructurallyImpossible and a trigger naming the CAPABILITY (one Nat
  declaration with the other derived), not an artifact. This lane did not
  create the fork but made it load-bearing by giving the Peano side real
  operations.
- OperatorRealizationRefusal typed its operator as String, a closed vocabulary
  flattened to text. Both variants now carry BinOp itself, producers pass the
  variant, and the single glyph spelling happens once at the message boundary.
  binop_label survives as that rendering fact with an annotation recording the
  corpus check: no BinOp-to-glyph producer exists elsewhere, so it is the first
  authority for the mapping rather than a second one. The rendered message text
  is unchanged, so the emitted-path witness pins the same bytes.

On review 57758 — three of the four findings are fixed in e1e14c8; this is the reasoning for the part of finding 3 I am not changing.

Fixed

  • src/v2/std/nat.dag:119 prose in a String row — converted to a module-scope // annotation on nat_max. The row predates this lane (The emission ratchet's subject is { root, kind, resolution policy }, and membership is observed beside it rather than folded into it #9238), but the file is this PR's to fix, so it is fixed rather than inherited.
  • The fork narrated without a dissolution schedule — now gunbc.guarantee_rung_drop two_nat_authorities_stall: current Mitigatable, ceiling StructurallyImpossible, AwaitsOneGrounding, bounded population, and a trigger naming the capability (one Nat declaration with the other derived from it) rather than an artifact. Deleting either declaration without deriving its operations would remove the operations its consumers call, which is why the trigger is written that way.
  • binop_label as a parallel operator-spelling authority — the concern is right in direction, so I went further than relabelling it. OperatorRealizationRefusal now carries BinOp itself in both variants instead of String; producers pass the variant; the spelling happens exactly once, at the human-readable message boundary. Nothing downstream can compare operators by string any more. On "the parser/emitter already owns it": I checked the corpus before keeping the table and could not find an owner — no BinOp-to-glyph producer exists anywhere in the tree, src/v1/compile.dag renders the variant name (Add), and glyph recognition happens in the tokenizer against token kinds, not a .dag row. So it is the first authority for that mapping, not a second one; the annotation above it now records that check. The rendered message text is unchanged, so the emitted-path witness pins the same bytes.

Not changing: OperandShapeFacts.connective / decl_file

connective cannot inhabit the connective coproduct without creating an import cycle. The value written into that field is v1.compiler.core's Connective (src/v1/00_core.dag:54), and v1.compiler.emit_rust already imports std.operator_realization (src/v1/05_emit_rust.dag:135). Typing the field as that coproduct makes std.operator_realization import v1.compiler.core, closing a cycle — and acyclicity is the substrate's one structural law under DESIGN §4, so it is not a trade I can make locally. v2.std.node's Connective is a different declaration and would not accept the value. The honest fix is one Connective authority both layers can import, which is a substrate move well outside an operator-realization change.

decl_file is deliberately not a citation. OperandShapeFacts is the payload of the arm where declaration identity could not be read, so a DeclarationRef is unconstructible there by construction — the whole point of the record is to report the shape the compiler actually saw instead of widening to a host token. This module does use std.decl_ref.DeclarationRef everywhere identity is available.

…in merge

The generated-artifact merge driver refused three mirrors (emitted_population,
lib.rs, v1_compiler_emit_rust) because both sides changed them since the merge
base, leaving them unmerged with the ours bytes in the worktree. These are the
projections of the MERGED authorities, produced by a regen round rather than by
taking a side.

Bootstrapped from main a6d6c68 laid across src/v1/stage0 AND every
src/v1/stage0_* sibling crate -- the siblings reach into stage0/src by #[path],
so a stage0-only lay dangles this lane's new mirrors (rustc said so directly:
couldn't read .../std_literal_elaboration.rs at stage0_std_core/src/lib.rs:130).
main_wet first so the generated partition .dag reflects the merged authorities,
--emit-partition-crates --write after each install, and five rounds each
rebuilding the seed from the installed tree and re-verifying:
first_generation_equal=true 148/148 every time.

Both sides survive in lib.rs, which is the check the driver refusal exists to
force: main's gunbc_stage0_executable_assembly_generated (the E0432 that made
all five jobs red) and this lane's std_operator_realization are both declared.

Closing: superseded by #9710, which merged this lane's substance to main (main@6ef73334e0b carries std.operator_realization, std.literal_elaboration, OperandDeclaration, and the Peano Nat operations).

Measured rather than assumed — a two-dot diff against the new main, since three-dot overstated (this branch's merge-base is old). What main lacked was exactly the review findings raised here after the 2177446 snapshot main carries: the String-typed refusal operator, the consumerless binop_is_ordering, the §4c prose row in src/v2/std/nat.dag, and the missing two_nat_authorities_stall. Those are rebuilt against main in #9794 rather than landed from this stale branch, which is now behind main and would revert newer work.

One row from here was deliberately dropped rather than carried: structural_connective_stall. Main declares StructuralConnectiveBinding and routes And/Or through structural_connective_realization, which is the capability that row named as its next-rung trigger — so it is retired, and re-adding it would have declared a stall its own trigger had dissolved.

…is branch stops carrying it

The previous merge kept XL-0N's admission alongside the five BootArtifact
rows because both were live and each dissolves with its own PR. #9719 has
now merged, so main's seventh dissolution removed that row by its own
trigger -- base and head both carry the relocation and no run can produce
its delta. Keeping it here would have been exactly what the roster's rule
forbids: a stale row that refuses every unrelated PR in the repository.

Main's ledger prose is taken whole, including the dissolution note, since
the roster's history is the reason each shrink is removable. The five
BootArtifact rows remain, still dissolving when this PR merges.

gunbc#9794's witnesses lane reported it exactly as the row predicted:

Removed by its own stated trigger, which is also why it could not be left: a
stale row here refuses every unrelated PR against main, so this was blocking
more than this branch. The floor itself was clean in that run
(verdict=FloorClean unexpected_failures=0); this phase was the only failure.

…a stall row, prose leaves the data plane (#9794)

* XL-0N residue: refusals carry the BinOp coproduct, the Nat fork gets a stall row, prose leaves the data plane

The review findings on #9719 (reviews 57754, 57758) that did not travel with
#9710. Rebuilt against main rather than landed from the stale branch, and
re-verified against main rather than assumed:

- dag/std/operator_realization.dag binop_is_ordering had no consumer corpus-wide
  (its sibling binop_is_equality is already absent from main). Deleted.
- OperatorRealizationRefusal typed its operator as String -- a closed vocabulary
  flattened to text. Both variants now carry BinOp itself, all nine producers
  pass the variant, and the spelling happens once at the message boundary.
  binop_label stays as that rendering fact, annotated with the corpus check that
  no other BinOp-to-glyph producer exists (v1's compile.dag renders the variant
  NAME; glyph recognition is in the tokenizer against token kinds). Rendered
  message text is unchanged.
- src/v2/std/nat.dag carried commentary as a String data row; converted to a
  module-scope // annotation on nat_max, the section 4c quarantine boundary.
- The two-Nat fork it narrated is now gunbc.guarantee_rung_drop
  two_nat_authorities_stall: ceiling StructurallyImpossible, trigger naming the
  capability (one Nat declaration with the other derived), bounded population.
  Verified still true on main: dag/std/nat.dag declares Nat as
  CommutativeSemiring<Magnitude> and src/v2/std/nat.dag declares the Peano
  coproduct, with nat_max in both.

NOT carried: the structural_connective_stall row from the old branch. Main
already declares StructuralConnectiveBinding and routes And/Or through
structural_connective_realization -- that IS the capability the row named as its
next-rung trigger, so main retiring it is correct and re-adding it would declare
a stall its own trigger has dissolved.

as superseded), so base and head both have it and no run can produce the delta.

* XL-0N: the Nat fork is ClimbableButUnbuilt, not awaiting a ruling (review 57807)

The row classified the two-Nat fork as AwaitsOneGrounding, whose grounding
sentence claimed the modeling direction was still undecided. Checked against the
authority the review cited and the review is correct:
gunbc.plans.dag_v2_defork_audit records the nat census complete with the
per-concept design DESIGN READY and its prerequisites discharged (algebra
FreeMonoid shadow #6341 merged, generic-alias coproduct keystone green), and it
specifies the cutover file by file -- dag/std/nat.dag takes the coproduct and the
Peano ops with the semiring alias deleted, v2.std.nat becomes a thin reimport
plus the node-bound law roster, integer and float repoint GroupCompletion<Nat>
to std.nat.Nat, every importer in the same push.

So the direction is decided and the work is scheduled: the blocker is
ClimbableButUnbuilt and the trigger now names that atomic wave rather than a
ruling nobody owes. Calling it a grounding question converted actionable work
into an indefinite decision stall -- the untracked stall DESIGN section 4b
forbids -- and diluted the canonical plan by implying the question was open.

* XL-0N: the Nat stall's population is UncountedNotEnumerable, not falsely bounded (review 57881)

The row declared BoundedPopulation while its second member was the open-ended
category "every reference site" rather than an enumerated identity -- bounded in
appearance only, which is what the carrier's second variant exists to prevent.

Checked whether the half could instead be enumerated, and the attempt is what
settles it: the property is about a module's CLOSURE, not its import list, and
closure membership is transitive -- a module importing one neighbour that reaches
std.nat and another that reaches v2.std.nat has both while importing neither. A
direct-import scan finds four dual-importing files and is therefore not that set.
Rendering those four as a bounded list would have read as bounded while measuring
the wrong property: an enumeration that is false the moment it is written.

So the carrier is UncountedNotEnumerable, and the reason keeps the enumerable
declaration half (the two declarations and the four forked operations) inside it,
states why the exposure half is not enumerable, and records that the population is
bounded in principle by the corpus and goes to zero with the trigger.

…-Unicode-scalar inhabitance carried into emission, text/list op realization by operand representation, no RustStdString row (#9720)

* Emitted v2 compiler crate: a declaration's identity is its last segment, and a primitive with no realization refuses instead of inventing one

Two roots behind 175 of the 260 rustc errors on the emitted v2 compiler
closure (issue #9664, milestones 1 and 2):

- 102 x E0425: the four DeclaredCallableIdentity constructions in
  v1.compiler.infer_lookup took decl_name from the AUTHORED spelling, so a
  qualified call carried the whole dotted path as the declaration name and
  emission rendered crate::v2_std_grammar::v2.std.grammar.f(..).

- 73 x E0425: v2.std.algebra length is a ModeledProjection of the `length`
  primitive and rt_function_registry has no `length` row, so emission took
  rust_runtime_bridge_name's identity arm and wrote v1_rt::length -- a symbol
  the seed does not define. A primitive's identity and its per-target
  realization are two facts; CallTargetIdentity carried only the first, so
  every emitter had to ASSUME a bridge exists.

RuntimePrimitiveCall now carries projected_from, the declaration the roster
projected it from, and emit_rust routes to the bridge only when its own
registry holds the primitive, falls back to the declaration otherwise, and
refuses when neither exists. DeclaredCallableIdentity moves to v1.std.core so
the target type can carry it without forking the pair.

* Class B: the algebra method fallback asserted a v1_rt bridge it had not checked

tier0 method resolution resolves an ordinary fn-typed RECORD FIELD through
lookup_field_in_product, so `algebra.step(..)` arrives as AlgebraMethodSemantics
carrying the field node as its method_def. The fallback at the end of that arm
hardcoded runtime_bridge: true, which emitted `v1_rt::step` -- and made
emit_rust_generic_method_call's own callable-field arm, guarded on
runtime_bridge == false, unreachable for the exact receiver it was written for.
65 E0425s on the emitted v2 compiler closure (member, apply, is_empty, step,
init, allocate_literal, ...) were that one literal.

It now passes the realization question keyed on the same registry as the
plain-call seam, so a real bridge method still lowers to a bridge, a callable
field lowers as a field, and a name that is neither reaches the existing loud
refusal rather than a fabricated symbol.

* Only ModeledProjection carries projected_from: a HostRealizedSeam body is a self-call, so falling back to it would emit a nonterminating function

The declaration fallback is sound only where the declaration's body is real
code. HostRealizedSeam means the body IS a self-call, so emitting it compiles
and then loops forever -- silent wrongness, strictly worse than the unresolved
symbol it would have replaced. A seam whose target has no realization has no
honest lowering, so it carries nothing and reaches emission's refusal.

* M1: realize the two symbol bridges, which were host seams nothing declared to be host seams

v2.std.compilers.lexing symbol_lexeme and symbol_intern_lexeme have self-call
bodies -- the HostRealizedSeam shape exactly -- and the interpreter has carried
real arms for both (v4_bridge.symbol_lexeme, v4_bridge.symbol_intern_lexeme).
With no projection roster row the resolver saw ordinary declarations, so Rust
emission emitted the declaration, and

    pub fn symbol_lexeme(sym: String) -> String { symbol_lexeme(sym) }

COMPILES. The emitted closure carried two functions that type-check, pass every
gate we own, and diverge from the interpreter by not terminating. Unlike the
sibling seams (decl_facts and friends, which at least refuse loudly as
unresolved v1_rt symbols) nothing anywhere reported this one -- it is absent
from the E0425 census precisely because it is silent.

extdeps.languages.rust.types already declares Symbol's target type as String,
so on this target both bridges are the identity. That is a realization of the
declared row, not a second opinion about it.

Residue named, not closed: a self-call body is a DECIDABLE structural marker of
a host seam, so the compiler could refuse an unrealized one rather than emit it.
It does not yet; that check is the class's next-rung trigger.

* test.claim fixtures: one discriminating RED per closed emission class, with boundary controls

Six rows over the three emitter defects plus the two symbol bridges. Each
class's positive and negative assertion differ only in the fact the repair
added, so no single edit satisfies both directions, and each repair carries a
boundary control that would go red had it over-reached the other way (empty_map
for the registry gate, a registered bridge method for the class-B gate).

The symbol-bridge row is deliberately not an error-count assertion: that class
COMPILED throughout the defect and diverged by not terminating, so a row
asserting 'no error' would have been green the whole time.

* Fix the class-B boundary control: count has a method template, so it never reaches the seam under repair

count is answered by rust_simple_method_specs before the algebra fallback, so
the row would have gone red while executing none of the code the repair
touched. trim is in rt_function_registry and has no template, so it is one of
the few names that actually reaches that fallback.

* The self-call seam wall: an unrealized host seam refuses instead of emitting compiling recursion

A whole-body self-call is the decidable structural marker of a host seam. In the
interpreter the shape is safe -- reaching it recurses to the evaluation-budget
refusal -- but emitted to Rust the same shape COMPILES and returns to no caller.
Nothing reported it: not the module index, not the compile-clean gate, not cargo
check. That is why the two symbol bridges were invisible until someone read the
emitted bytes.

emit_fn_def now asks the realization registry -- the same authority the call
sites ask, so the two cannot drift -- and suppresses the declaration when the
seam is realized, refuses with a located message when it is not. Suppression
rather than delegation is deliberate: a forwarding body would make this seam
reconstruct signatures in target types, which is the cementing the existing
suppressed-seam precedent avoids, and a realized primitive's calls all route to
the bridge anyway.

The predicate is whole-body identity, not 'contains a self-call'. Ordinary
recursion has a match, an if or a let between the head and the call, so it never
matches; expr_has_self_call walks children and would have refused most of the
compiler. Both directions carry a fixture.

* The seam wall must resolve realization through the roster's primitive, not the declaration name

Measured, not predicted: the wall refused six seams in the emitted closure and
one of them -- v2.std.collection empty_map_primitive_delegate -- is realized.
Its roster row names the empty_map primitive, whose bridge is rc_empty_map, but
rt_function_registry holds 'empty_map' and the wall looked up
'empty_map_primitive_delegate'. A declaration's name and the primitive it
realizes are two facts; the roster is the authority that joins them, and the
declaration name is only the fallback for a seam nobody has rostered.

* The seam wall's realized arm must not suppress the declaration: suppression created 10 dangling imports

Measured on the emitted closure with the wall finally in the mirror: removing a
realized seam's item left 10 unresolved imports (E0432) for symbol_lexeme,
symbol_intern_lexeme and resolve_type_node. Other modules import these
declarations; the suppression created that breakage rather than finding it.

And the reasoning that made suppression look safe is what makes it unnecessary.
A realized seam's body IS a call to itself, and resolution already routes that
call through the roster to the bridge -- so ordinary emission writes
v1_rt::symbol_lexeme(sym) as the body without help. The wall's whole job is the
UNREALIZED arm.

* The seam refusal is a generated body, not a crate-wide compile_error!: rustc's denominator is larger than the demand denominator

compile_error! fails the WHOLE crate, and that form silently assumes every seam
it refuses is one somebody calls. It is not. rustc type-checks the entire
emitted crate including declarations imported but never invoked, so the refusal
denominator is strictly larger than the entry-reachable execution closure --
five unreachable seams took the crate down.

The refusal is now a panic body with the declaration's real signature: dependent
modules resolve, the crate compiles, and only an actual invocation fails loudly.
That moves the refusal from the crate to the one declaration that earned it, and
leaves reachability to a separate instrument. An entry-rooted pruner can replace
the body later without revisiting this.

* Two obligations the required floor found, both real consequences of this change

DETERMINISM DENOMINATOR (9 reach_witness rows red, including
determinism_denominator_is_closed_on_declared_primitives, whose entire job is to
notice this). v2.lens.determinism closes its denominator over
primitive_declared_definitions, so adding two canonical names without traversal
facts made the closure false. Both bridges are scalar -- symbol_lexeme maps one
Symbol to its text and symbol_intern_lexeme is its inverse -- so there is no
collection to walk and OrderFreeResult is the honest arm. HostUnspecifiedOrder
would claim a real traversal whose order the host does not pin, fabricating a
leak the primitive cannot have.

NAMESPACE WAVE ADMISSION (6 unadjudicated deltas). Four are TargetChanged for
DeclaredCallableIdentity moving v1.compiler.infer_sigs -> v1.std.core, which is
what lets CallTargetIdentity carry the declaration a runtime target was
projected from. infer_sigs imports v1.std.core, so the type could not stay put
without a cycle. Four enumerated rows, one per binding site; the two membership
deltas auto-admit as ExplicitlyEvaluatedZeroDelta. Dissolve-on: this PR merging,
by the same trigger the three prior shrinks record.

* Class-C fixture was broken, not the repair: the witness pool is smaller than the corpus

The row FAILED while the mechanism was green. The probe used the qualified
spelling without importing v2.std.collection, which resolves against the real
4261-module corpus but not against compile_dag_rust_emit_check's 2973-module
witness pool. Measured both ways: emitted against the corpus the same probe
produces crate::v2_std_collection::map_get(m.clone(), "key".to_string()),
exactly what the row asserts.

The import restores module presence and does not answer the call -- decl_name
comes from the authored spelling at the call site regardless of imports -- so
the negative assertion still discriminates. Falsifier 2 is what proves that
rather than argues it.

* is_empty: a conversion is not a repair -- give it the Rust realization it never had

Before the class-B change, xs |> is_empty emitted v1_rt::is_empty, a symbol the
seed does not define: 5 x E0425. After it, the same 5 sites became typed
refusals -- correct in kind, still 5 errors. The class-B repair made the gap
visible; it did not close it.

is_empty is an algebra template over FreeMonoid whose Rust realization is
Vec::is_empty, exactly as count's is Vec::len, so the fix is one row in
rust_simple_method_specs beside count. Nothing in 05_emit_rust learns a new
name: realization is a target fact and lives in the target's registry.

* A receiver's own callable field outranks every name-keyed table: class B survived one layer up

The requested is_empty negative control found a live hole rather than confirming
a safe one. Both rust_method_templates lookups are keyed on the bare method
spelling with no receiver check, so a fn-typed record field named is_empty was
captured by the target template and emitted as recv.is_empty() instead of
(recv.is_empty)(..). The class-B repair fixed the algebra FALLBACK and left the
two tables sitting in front of it.

The hole is not new and is not specific to is_empty: count, first, join, split,
take, skip, last, chars and enumerate have carried it for as long as they have
had templates. Adding is_empty made it urgent by putting the spelling most
likely to name a predicate field in front of that table.

One helper, consulted at the top of both arms before every name-keyed special
case, so the two cannot drift. Two controls: the new spelling and a pre-existing
one.

* Two more wave admissions: the declaring module rebinds too

v1.compiler.infer_sigs used to DECLARE DeclaredCallableIdentity, so its own two
construction sites resolved locally and produced no delta. Now that the
declaration lives in v1.std.core and infer_sigs imports it, those sites rebind
exactly like the consumers in infer_lookup. An enumeration error on my part, not
a second transition: same subject, same trigger, same dissolve.

Floor is now green on this branch (passed=2754 failed=0) -- the OrderFreeResult
traversal facts closed all nine determinism rows.

* The callable-field tier was consuming the algebra profile's identity domain, not the receiver's: 202 refusals on the first compile of the converged seed

rust_receiver_has_callable_method_field asked rust_record_field_needs_fn_rc,
which sweeps rust_struct_field_lookup_candidates -- and that list deliberately
widens a receiver's name to its container template algebra. An algebra declares
its operations as arrow-typed members, so under that widening every Map receiver
"has a callable field" named map_keys, map_values, lookup or get, and the tier
captured the very bridge calls it sits in front of.

Measured at the first compile of the round-3 converged mirror: 202 rustc
refusals, one class -- 164 E0609 (no field `map_keys` on
Rc<im::HashMap<String, Rc<ItemInfo>>> and friends), 48 E0282, 4 E0615 on `get`.
It is the same defect the tier was built to close, one level up: a name-keyed
lookup consuming an identity domain that is not its own.

The predicate now consults only the receiver's own declared record.
w_map_receiver_operation_is_not_read_as_a_callable_field is the discriminating
red: restore the candidate sweep and its must_not_contain clause fires.

* One renderer for every arrow position; a type position never takes the variant arm; the qualified route synthesizes use-lines only for types the emitted source names

Four regressions the 0773184 fixed point put on the closure, each with its discriminating row:

- E0603 x16: the qualified-type route synthesized `pub use crate::v2_std_nat::Succ;` for every
  `v2.std.nat.Succ { prev: .. }` record literal. A qualified name reaches the surface walk in the
  same dotted spelling whether it is a type or a variant head; the route now asks the registry
  whether the leaf is a TYPE declared in the named qualifier, records each decision as a census
  row, and considers only leaves the emitted source actually names (it had also synthesized an
  unused `DeclarationRef` import from a variant payload).
  w_qualified_variant_head_earns_no_type_use_line.

- `Outcome<compile_error!("UNRESOLVED_CompilerError")>` x3 and `Rc<Medium>` E0107: two cuts had
  each introduced a second per-position renderer for arrow types beside the one fn parameters use.
  An arrow's return is not a different kind of type from its parameter: both positions now render
  through render_rust_fn_sig_type, and render_rust_type_with_applied_binding -- which rebuilt its
  EmitGraphInfo with an empty generic scope, so a fn-scope `C` rendered `_` (E0121) -- carries the
  fn's generic names through that hop. The measured gate over the second renderer is deleted.
  w_generic_arrow_return_renders_the_fn_scope_generic; w_arrow_return_type_keeps_its_applied_binding
  (its fixture was an invalid program: Accepted lacked `diagnostics`).

- v2.std.determinism E0425 x2: traced to the bare-name disposition, not the qualified route --
  `Determinism` is a type in std.determinism and a variant of v2.lens.registry LensIdV0, and
  is_known_variant is corpus-wide by spelling, so a TYPE-position reference was delegated to an enum
  it never named. A name in one of the module's type positions never takes the variant arm.
  a_known_variant_spelling_in_a_type_position_takes_the_registry_arm (red by construction on the
  old arm); the harness row is a positive control and says so, because the witness harness refuses
  any pool carrying the colliding variant with NoSuchVariable.

Verified on a test binary built from the self-emitted emitter (not a regeneration): witnesses
23/24 -> 24/24 after the harness row was reshaped; closure instrument 2799 -> 2779. The regeneration
that binds these to the mirror follows as its own commit after the freeze merge.

* Witness fixture only: the qualified-type positive control moves to a provider the harness pool can carry

Post-freeze, fixture-only (dag/test/claim is not a regen-population path; a no-drift regen run on
this head is recorded in the PR). Two harness facts, both measured on the fixed-point artifact
gunbc=974aafe864f743f6: a `{Determinism}` inside a .dag string literal is read as an interpolation
of that name (the row failed in the interpreter before any compile ran), and the harness pool is the
probe's DECLARED import closure, so a provider referenced only by a dotted name is absent -- and
std.determinism cannot enter it because its own body references std.perturbation the same way. The
row now uses std.decl_ref with a sibling import and says plainly that it is a positive control; the
class's discriminating red stays at the disposition grain
(a_known_variant_spelling_in_a_type_position_takes_the_registry_arm) and in the closure count.

v1_compiler_trait_derive_emit.rs (the two files commit 2 edits), round 2 byte fixed point;
installed tree 7fcf44b9f5c9df97, gunbc 2146d1f1844dea92. Unit 552/0. Emitted closure
cargo check 420 -> 392; line-insensitive identity diff vs the merged-tree base: 28 removed,
0 added (E0061 x6 vocab arity, E0599 GlobalBare* x4, E0004 x7, E0533, E0271, E0618 x2,

* A1: relocate the import-admission helpers to their consumer layer; C: one storage representation for Map at every position

A1 (closure prune). Counting fully qualified code references as declared edges, the declared
closure from v2.compiler.compile equals the emitted set: no module enters by bare-name binding.
The carrier was 03_name_resolve importing v2.lens.reference_deps for admission_from_module_root /
import_rows_from_parsed_module / collect_import_decl_nodes / ImportRowsState, consumed only by
v2.workflow.compile_door_ledger and self_host.frontier_probe (both outside the closure, both already
importing reference_deps). They now live in reference_deps; the two consumers import them there.
Emitted closure drops 8 modules (lens.coverage, enforcement.{grammar_coverage,standing_intent,vocab},
registry, module_graph, reference_deps, std.decl_index) and all 6 host-primitive panic sites.

C (Map). The six PartialFunction<..> positions (InferredTree.facts, EvaluationEnvironment.bindings,
four signatures) are Map<..>; the four PartialFunction { lookup: .. } constructions are empty_map()
or a first-wins map_insert fold; map_insert routes through a rostered map_insert_primitive_delegate
(closure body deleted); slots.lookup -> map_lookup. Emitter: the alias RHS renders a keyed/element
collection through the host template (type X = Map<A, B> -> Rc<HashMap<..>>), and a generic in map-key
position carries std::cmp::Eq + std::hash::Hash from the signature. Two witness rows added.

* C corrected: InferredTree.facts stays the open PartialFunction; PartialFunction realizes as its algebra struct everywhere (HashMap rows deleted); frontier row dissolved; two TargetChanged admissions

The CI floor on 4da6059 showed the facts retyping over-reached: about 120 test and fixture sites
plus program.dag / 05_emit_orchestration define InferredTree.facts by a predicate closure, which
is exactly what the open carrier is for. inferred_tree / 04_infer / program_partition are restored.
The fork was the emitter realizing PartialFunction as HashMap in signature position and as the
algebra struct in field position; the PartialFunction HashMap rows in extdeps.languages.rust
(types.dag row, the partial_function template) are deleted so one representation stands.
EvaluationEnvironment.bindings stays Map (built by map_insert); v2_effect_io_pure's empty
environment is empty_map(). The v1 unresolved_method_frontier row for target_model lookup /
Primitive(T) is deleted: the slots.lookup -> map_lookup rewrite dissolved its one occurrence.
The two TargetChanged binding deltas for admission_from_module_root (frontier_probe,
compile_door_ledger) are admitted by exact subject in namespace_wave_admission.rs.

* Commit 3 of the #9664 closure: six emitter mechanisms, the null keyword by path, and map_insert back to its .dag body under the gate's ruling

Emitter (src/v1/05_emit_rust.dag, trait_derive_emit.dag), each with a discriminating row in
self_host_emitted_call_target_realization_witness_test (pre-fix bytes observed on the seed):
- an argument into a parameter spelled Optional<T> is not unwrapped (the cardinality flag marks
  only the T? sugar; the applied spelling is asked too)
- the shared-field accessor impl of a generic coproduct carries T: Clone
- a Violates literal in a record field takes the field's Witness carrier before the fn return
- a record pattern over a shared carrier derefs like a shared enum's variant pattern
- a fn returning an arrow-field record carries 'static on its generics (same gate as impl Fn)
- the fn-field record header prints well-formedness bounds asked per parameter instead of the
  bounded set minus the seed set (FalsificationReceipt<Subj, A> lost A behind ValueDiff<A: Clone>)
- extdeps.languages.rust emit: the null keyword is std::option::Option::None, because a module
  declaring a nullary variant named None emits pub struct None; at module scope (std.cache_interface)

v2.std.collection: map_insert is its .dag body again and map_insert_primitive_delegate with its
primitive_projection row is deleted. The delegate tripped map_carrier_shape_gate on CI at c6d9b22
(record_shaped_map_reaches_map_insert BUDGET-REFUSED): the interpreter's free_call.map_insert arm
answers Ok(None) for a non-native shape and the grounding falls through to the delegate's own
body, a self-call -- the deferred-refusal class #8887 filed. The closing move is a host fact
(a typed refusal in try_v2_std_collection_map_primitive_grounding) and is ledgered in the PR body,
not landed here, by the manager's ruling.

* Partition mirror + std-core crate carry std_literal_elaboration; rung-drop row per ruling (two-path standing, identity-census population, A/B trigger); planted non-literal restoration probe

The roster edit only reaches the crate renderer through its compiled-in mirror
(gunbc_stage0_crate_partition_generated.rs), so the sequence is projection ->
regen -> rebuilt claim_executor -> emit-partition-crates, which wrote the
std-core lib.rs row that clears the partition E0432.

The rung-drop row is reworked to the ruling's grain: no rung claimed for the
withdrawn wall, emitted-Rust path mechanically preventable vs source-acceptance
path unguarded (never averaged), population bounded by identity with the wall
re-applied as the named producer, and the two-direction A/B restoration
trigger. The witness battery gains the planted non-literal probe asserting the
present acceptance.

* Exact identity for a resolved alias destination: type_reference_declaration_ref falls back to the reference's env binding when the resolver's substitution carries the occurrence span

The resolved-alias case (v2.std.text String = FreeMonoid<Char>) answered none
from the census because the substituted node's ident_span is the annotation
site, so every text.String literal boundary elaborated as DirectLiteral while
the declared coproducts Bool and Nat worked. Second hop = the same env-binding
read e51aff9 added for in-place recursive references; both hops answer by
declaration span from the census, never by spelling. Also carries the
partition std-core lib.rs write from the converged round.

* Third identity hop: a resolver-qualified authored name joins the census by (module_path, name)

Modules that reference a type with no import resolve it by the resolver's
qualification, so lookup_type_for has no binding and both span hops answer
none while the emitter still realizes the structural carrier -- the literal
boundary stayed DirectLiteral exactly there (measured: the data prose rows in
v2.compiler.source_authority and extdeps.languages.dag, which import no
String). The qualified prefix is joined against the census row, never trusted
as a spelling.

* The unique-census hop is the terminal fallback for EVERY Absent outcome of the identity hops, not only the by-name arm -- the measured failing path was lookup_type_for answering a binding whose census read fails, which returned Absent without ever consulting the census

* One subject, one answer at the literal boundary: the natively-realizes fact is read from the DESTINATION declaration's census file, not re-derived from the reference node's span -- a kernel-minted annotation span (<kernel:String>) answered natively=TRUE against a v2.std.text.String destination, keeping the literal direct at a structural boundary; node-span file remains the fallback when the census has no row

* Type repair: route the census-file read through span_file_string so the FilePath product coerces at a String return boundary (the inline if/else mixed Product(FilePath) with a String literal and regen refused, invalidating the prior round's probes)

* One authority for the text spelling: render_rust_text_carrier consults type_reference_declaration_ref + the destination census file -- the same reader the literal boundary uses -- rendering a structural destination as the qualified crate path and everything else bare; the module-binding heuristic and grounding spelling are deleted (both measured wrong in opposite directions)

* Retract the terminal unique-census hop: a corpus-unique declaration is not the destination of a reference the module never bound -- it invented structural identities for the whole kernel corpus (census 108->569/437 measured). The census read survives only where a module-level binding EXISTS and its own census read fails, and as the natively-coherence file source. Consistency now rests on the one-authority renderer: infer and emit consult the same reader, so whichever answer identity gives, annotation and value agree

* Mirror reset to main's self-consistent set (the ours-side merge resolution mixed pre-main mirrors with main consumers of compile_sources_selected -- E0432 on round 1); hand-maintained interpreter arms re-inserted (4 ExprElaboratedLiteral arms, EXPR_VARIANT_COUNT 23)

* Interpreter mirror back to main's for bootstrap round 1 (the hand arms reference ExprElaboratedLiteral, which only regen adds to v1_std_core); the arms are re-inserted mid-convergence and land with the regen commit

* Revert the identity-reader widenings and emitter spelling experiments to the c7b8056-compatible three-hop state, recording each measured failure in place: leaf-name guard 108->174, terminal census hop ->569, module-binding rederivation ->437, one-authority renderer ->745. The shadowed-module class stays open under the boundary-lane declared drop with its fix shape on the class row; natively-coherence (destination census file) is kept

* Complete the revert: natively back to the node-derived decl_file (the census-file coherence read was deleted with the census hops and its consumer refused regen)

* Merge repair: the row-union dropped my class row's evidence/closing lines when the conflict markers were stripped mechanically -- both rows now well-formed (this parse error silently refused regen, which my capture filters then hid)

* Regen: mirrors converged at first-generation byte fixed point on the merged tree (rounds 2, 3 and the final rebuilt-binary check all equal); interpreter hand arms restored; DESIGN/design-ledgers projections carry both new recurring-failure class rows

* Round-1 bootstrap coherence: stage0_std_core lib.rs taken from main alongside main's stage0 mirror set (regen re-derives the literal-elaboration rows)

* Regen: converged at first-generation byte fixed point on the round-1 bootstrap tree — literal-elaboration/operator-realization/structural-bindings mirrors re-derived and installed, partition lib rows and the four ExprElaboratedLiteral interpreter hand arms restored (EXPR_VARIANT_COUNT 23)

* Regen: converged at first-generation byte fixed point on the re-cut tree (round 2 equal) — the mirror delta vs main is exactly the four text-family files the re-added UnicodeScalarSequenceUnfold row touches

* Floor fixes for the re-cut head: totalize the two LiteralUnfolding matches in peano_nat_structural_realization_test over the re-added UnicodeScalarSequenceUnfold variant (both witnesses PASS scoped), and retire the XL-0N #9719 wave-admission row by its own dissolve-on trigger (base and head both carry the relocation; the run on bc74b2e reported it stale)

* Re-cut floor recovery: restore the literal-destination identity hops (declaration_ref_of_type_node with by-name + qualified-census fallback, scoped to the elaboration destination read; XL-0N's operand reader untouched), delete the resurrected name-keyed text op overrides and host_string_text seam arms from 05_emit_rust, restore the ExprElaboratedLiteral arm in data-value emission, and narrow the ops witness excludes to the overrides' exact receiver forms (bare .is_empty() red the structural Vec lowering — substring-oracle over-match). Text battery 11/11, peano 29/29, regen at byte fixed point

* Post-merge repair: rebuild rung_drop.dag from main's version plus the text_boundary_identity_wall row intact (the union regex had split on a '=======' line inside an authored string — parse error at the module index), retake main's stage0 set (the generated-artifact merge driver had left ours-bytes marker-less on namespace_wave_admission.rs), regen re-derives the six text-family mirrors to the byte fixed point (round 2 equal); text battery 11/11, peano 29/29

* Structural key for the text literal homomorphism: the row keys on what survives resolution (FreeMonoid+Char), natively reads the destination's own declaring file, witnesses re-anchor on the qualified boundary

The #9813 kernel-precedence landing exposed that the text row was keyed on
information resolution deliberately discards: String is a container-alias
spelling, so every 'type X = FreeMonoid<Char>' boundary peels to the bare
structural carrier and no module spelling survives to key on. The row now
keys on that surviving structure — destination std.algebra.FreeMonoid with
element std.types.Char (LiteralHomomorphism gains an element field,
threaded through literal_homomorphism_for/elaborate_literal_at; peano and
bool rows carry element: none).

Second repair on the same boundary: destination_realizes_natively was read
from the RESOLVED NODE's ident_span file, and a substituted alias RHS is a
kernel-minted node whose pseudo-file <kernel:std.algebra.FreeMonoid>
string-matched the '<kernel:' native-numeric roster row, so the peeled
structural boundary answered natively=true and took DirectLiteral with the
matching row present. natively is now read from the DESTINATION
declaration's own census file (declaration_file_of in 04_env), per
numeric_realization_identity_note's own rule that realization is a fact
about the declaration.

Witness battery re-anchored per the division ruling: the seven positive
rows probe the QUALIFIED v2.std.text.String boundary (each probe imports
string_is_empty so the harness's import-following closure loads the text
module), and a new control pins bare String + text import = host,
deterministically, under uniform kernel precedence. 12/12 text rows and
29/29 peano rows green by execution; stage0 mirrors regenerated to
first-generation byte fixed point on the merged tree.

Also: recurring_failure_mode row mistyped_body_radiates_nonlocal_diagnostics
(the phantom-diagnostic specimen, layer stated), DESIGN.md and
docs/design-ledgers.md regenerated via generated_artifact_gate main_wet_one,
stale rust_host_string_seam_fn_emit comment fixed (review 57929).
