Section 01: Burden Registry

Status: complete Goal: Establish the BurdenSpec data layer (per-type drop information as queryable data, not compiled IR) sibling to BUILTIN_TYPES (pure-const, ori_registry::defs::mod.rs:68) + heap-backed TypeDef metadata on TypeRegistry. Two distinct struct types (BuiltinBurdenSpec for pure-const path, UserBurdenSpec for heap-backed path) bridged by a Burden trait per decisions/05-burdenspec-storage-model.md.

Success Criteria: see frontmatter.

Context: Per proposal §BurdenSpec — Pure-Const Data Model + Registration is split by type origin (codex R8 Finding 3). Prior-art surface in this repo: BUILTIN_TYPES: &[&crate::TypeDef] at compiler_repo/compiler/ori_registry/src/defs/mod.rs:68 (pure-const builtin metadata) + TypeRegistry::register_struct/register_enum/register_newtype at compiler_repo/compiler/ori_types/src/registry/types/mod.rs:183/218/254 (heap-backed user metadata via TypeDef/StructDef/VariantDef). BurdenSpec joins this same partition. MethodRegistry at compiler_repo/compiler/ori_types/src/registry/methods/mod.rs:19 is a placeholder thin wrapper for trait method lookup; builtin method dispatch routes through resolve_builtin_method() consulting BUILTIN_TYPES directly per types.md §RG-3 — NOT through MethodRegistry.

Reference implementations:

• Ori compiler_repo/compiler/ori_registry/src/defs/mod.rs — BUILTIN_TYPES: &[&TypeDef] pure-const pattern.
• Ori compiler_repo/compiler/ori_types/src/registry/types/mod.rs:104,168,183 — TypeRegistry + StructDef + register_struct heap-backed user metadata.
• Ori compiler_repo/compiler/ori_types/src/check/registration/user_types.rs:70,135,150 — integration hook for user-type registration (called from typeck phase 0b per typeck.md §CK-1).
• Lean 4 IR/RC.lean per-type drop walks — algorithmic shape parallel to BurdenSpec.field_type chains (per proposal:222).

Depends on: Section 00 (Phase A0 PASS with outcome: registry-justified).

01.1 BurdenSpec data structures (ori_registry::burden + ori_types::registry types)

File(s):

• compiler_repo/compiler/ori_registry/src/burden/mod.rs (new) — BuiltinBurdenSpec + field structs (&'static [...])
• compiler_repo/compiler/ori_types/src/registry/burden.rs (new) — UserBurdenSpec + owned field structs (Vec<...>)
• compiler_repo/compiler/ori_arc/src/lower/burden.rs (new) — Burden trait + BurdenRef<'a> enum

Schema source: All field schemas defined in decisions/05-burdenspec-storage-model.md §Type Schemas. The decision file fixes TransferRule’s exact field set (source_field_path: &'static [u32], binding_index: u16, field_type: TypeId, transfer_kind: TransferKind) derived from the owned-binding extraction obligations at proposal:260-282.

Tasks:

• Create ori_registry::burden module per decisions/05-burdenspec-storage-model.md §Type Schemas — BuiltinBurdenSpec block (verbatim Rust): BuiltinBurdenSpec, OwnedField, BorrowedField, VariantBurden, TransferRule, TransferKind.
• Verify registry.md §Invariants compliance: NO String / Vec / Box / Arc / HashMap anywhere in ori_registry::burden. Use &'static [...] slices. Add const _: () = { assert!(size_of::<BuiltinBurdenSpec>() <= 64); };-style compile-time pure-const compliance check.
• Add #[derive(Debug)] only on BuiltinBurdenSpec — no Clone (forced const, all fields are Copy-eligible references / scalars).
• Create ori_types::registry::burden module per decisions/05-burdenspec-storage-model.md §Type Schemas — UserBurdenSpec block (verbatim Rust): UserBurdenSpec, OwnedFieldOwned, BorrowedFieldOwned, VariantBurdenOwned, TransferRuleOwned. Re-export TransferKind from ori_registry::burden to keep the enum SSOT in one place.
• Create ori_arc::lower::burden module with the Burden trait + BurdenRef<'a> enum per decisions/05-burdenspec-storage-model.md §Bridge trait + BurdenRef<'a>. View types (OwnedFieldView/BorrowedFieldView/VariantBurdenView/TypeRef) implemented as Cow<'a, [u32]> / enum wrappers as sketched.
• Rust unit tests split by crate ownership (codex F2 cohesion-edit — ori_registry is zero-deps + cannot host Burden trait dispatch): pure-const compliance lives at compiler_repo/compiler/ori_registry/src/burden/tests.rs (compile-time const _: () = ... assertions on BuiltinBurdenSpec data only — no trait method calls); Burden trait method dispatch parity on a synthesized BuiltinBurdenSpec + a hand-built UserBurdenSpec with structurally-equivalent shape lives at compiler_repo/compiler/ori_arc/src/lower/burden/tests.rs (the crate that owns the Burden trait + BurdenRef<'a> enum per §01.1’s module path).

01.2 BURDEN_TABLE entries for builtin types (const templates only)

File(s): compiler_repo/compiler/ori_registry/src/burden/table.rs (new)

Scope boundary (per blind-spot codex #1): §01.2 defines the const-template schema for builtin types ONLY. Generic builtins (Option<T>, Result<T, E>, [T], {K: V}, Set<T>, Range<T>) are represented in BURDEN_TABLE as TEMPLATES — entries whose OwnedField.field_type references the type parameter’s TypeId placeholder. Monomorphized first-instantiation entries (Option<int>, Result<{str:int}, str>, etc.) are owned by §02 Burden Composition per proposal:165-172 and decisions/02-monomorphization-pipeline-ordering.md. §01.2 does NOT compose monomorphized entries; §02 reads §01’s templates and emits the composed shapes.

Tasks:

• pub const BURDEN_TABLE: &'static [(TypeId, BuiltinBurdenSpec)] = &[ ... ] — one CONST TEMPLATE entry per builtin:
  • primitives (int, float, bool, char, byte, void, Duration, Size, Ordering): empty BuiltinBurdenSpec (no heap, no fields, no variants) per proposal §Value Trait Composition.
  • heap collection templates (str, [T], {K: V}, Set<T>): self_heap_alloc: true + element_burden: Some(<typeparam-placeholder-TypeId>). str carries element_burden: None (UTF-8 bytes, no recursive burden).
  • sum-type templates (Option<T>, Result<T, E>): variant_burdens: &[VariantBurden { variant_id, transfers_on_match, retained_owned }] per variant. transfers_on_match populated per the owned-binding extraction obligations at proposal:260-282.
  • Range<T>: empty BuiltinBurdenSpec (range bounds are inline scalars; no heap, no recursive burden).
• FFI types (CPtr, JsValue, JsPromise<T>): empty BuiltinBurdenSpec (caller-managed lifetime per proposal:643-645 / Q12). The FFI-exclusion contract (sound only for caller-managed; annotated #free types route via UserBurdenSpec) is owned by §01.5.
• BurdenRegistry::lookup_builtin(type_id) -> Option<&'static BuiltinBurdenSpec> — linear scan (BURDEN_TABLE is bounded; this is fine).
• Tests in compiler_repo/compiler/ori_registry/src/burden/tests.rs: every builtin TypeId has correct BuiltinBurdenSpec template; lookup misses return None; BurdenRegistry::lookup_builtin(<user-type-id>) returns None.

Subsection close-out (01.2) per protocol.

01.3 TypeRegistry::burden field on user-defined types — registration hook at user_types.rs

File(s):

• compiler_repo/compiler/ori_types/src/registry/types/mod.rs:40 — add burden: Option<UserBurdenSpec> field to TypeEntry (sibling to repr field at line 74) per decisions/06-burden-field-placement.md
• compiler_repo/compiler/ori_types/src/check/registration/user_types.rs:70,135,150 — primary integration call sites (3 user-type sites)
• compiler_repo/compiler/ori_types/src/check/registration/builtin_types.rs:78,144,201,258,305,396 — secondary integration call sites (6 builtin-type sites)
• compiler_repo/compiler/ori_types/src/registry/types/tests.rs:37,86,128,210,220,230,256,286 — test integration call sites (8 sites)

Field placement decision (cures blind-spot opencode STRUCTURE:decision-in-implementation): Decided at plan-edit time via decisions/06-burden-field-placement.md. The burden: Option<UserBurdenSpec> field lives on TypeEntry (compiler_repo/compiler/ori_types/src/registry/types/mod.rs:40), NOT on StructDef / VariantDef / TypeKind. Sibling to existing repr: Option<ori_ir::ReprAttrKind> field at mod.rs:74. §02 (monomorphization), §03 (Phase 5 emission), §04 (RL-31 noalias) reference TypeEntry.burden slot; consumers query via TypeRegistry::burden(idx) -> Option<&UserBurdenSpec> returning &self.types_by_idx.get(&idx).and_then(|e| e.burden.as_ref()).

Phase-bleeding cure (cures blind-spot gemini-only finding): §01.3 partitions UserBurdenSpec.owned_fields vs borrowed_fields by ori_types::triviality::Triviality (compiler_repo/compiler/ori_types/src/triviality/mod.rs:26-35), NOT by ori_arc::ArcClass. Triviality is the SSOT (triviality/mod.rs:7-8: “both ori_arc::ArcClassifier and ori_llvm::TypeInfoStore delegate to classify_triviality”); using it from §01.3 (typeck phase 0b) is downward-only and respects phase boundaries (compiler.md §Phase-Specific Purity). Mapping per decisions/06-burden-field-placement.md §Phase Boundary Cure:

• Triviality::Trivial → borrowed_fields (no heap reference; field-walk does NOT recurse)
• Triviality::NonTrivial → owned_fields (heap-allocated child; field-walk recurses via element_burden/field_type)
• Triviality::Unknown → conservatively owned_fields (defaults to RC-correct; PC-2 violation if reached at typeck exit per typeck.md §PC-2)

Integration hook (per blind-spot gemini #3): The architectural-wiring decision is named here, NOT deferred to implementation. User-type registration call sites are:

• register_struct invocation at user_types.rs:70 (struct decls)
• register_enum invocation at user_types.rs:135 (sum decls)
• register_newtype invocation at user_types.rs:150 (newtype decls)
• register_alias invocation at compiler_repo/compiler/ori_types/src/registry/types/mod.rs:284 — type-alias declarations (type N = Existing); burden is structurally INHERITED from the aliased type, not stored independently. Alias entries SHALL store burden: None and the lookup helper SHALL transparently follow the alias edge to the target type’s burden (consistent with TypeKind::Alias aliasing semantics per types.md §TI-5).

Each call site computes UserBurdenSpec from the declaration shape (StructDef.fields: Vec<FieldDef> per ori_types/src/registry/types/mod.rs:104 → owned_fields/borrowed_fields partition by Triviality per phase-bleeding cure above; VariantDef.fields: VariantFields per types/mod.rs:133 → variant_burdens). The register_* API SHALL be extended to accept the computed UserBurdenSpec so registration is atomic (TypeEntry and its burden ship together; no two-phase write).

Caller blast radius (cures blind-spot gemini 2-of-3 finding + Round-2 codex-F1 register_alias + Round-4 gemini-F1 INTEL_BYPASS): Verified via scripts/intel-query.sh callers register_struct --repo ori + callers register_enum --repo ori + callers register_newtype --repo ori + callers register_alias --repo ori (intel-graph queries; supersedes prior grep citation per intelligence.md §Graph-First Mandate) — 17 caller sites total beyond the 4 primary user_types.rs + alias-decl sites:

• builtin_types.rs:78 register_enum (Option), :144 register_struct, :201 register_enum (Result), :258 register_enum, :305 register_enum (Ordering), :396 register_struct — 6 builtin-type registration sites that ALL must compile after signature change.
• registry/types/tests.rs:37 register_struct, :86 register_enum, :128 register_newtype, :210/220/230/256/286 register_struct — 8 unit-test sites that ALL must update to pass burden: Option<UserBurdenSpec> argument (typically None for the test fixtures since they exercise registry mechanics, not burden semantics).
• register_alias at registry/types/mod.rs:284 is the 4th register_* function (NOT one of the original 3); the §01.3 signature-change scope INCLUDES register_alias per Round-2 codex-F1. Alias entries store burden: None (burden inherits from aliased target via the lookup helper); same Option<UserBurdenSpec> parameter pattern applies.
• pool/accessors/resolution.rs:35 register_newtype_ctor is a sibling register_newtype_ctor constructor-level helper (NOT one of the four register_* functions); confirmed unaffected by this signature change.

§01.3 implementation MUST update ALL 17 caller sites in the same commit as the register_* signature change to preserve compile-cleanness across ori_types. Verification gate: cargo c -p ori_types && cargo t -p ori_types clean after change.

Tasks:

• Add pub burden: Option<UserBurdenSpec> field to TypeEntry at compiler_repo/compiler/ori_types/src/registry/types/mod.rs:40 per decisions/06-burden-field-placement.md (sibling to repr field at mod.rs:74).
• Extend register_struct / register_enum / register_newtype signatures (mod.rs:183/218/254) to accept burden: Option<UserBurdenSpec>. The Option wrapper allows None for types whose burden is empty (all-Triviality::Trivial fields, all-scalar primitives newtyped) — preserves the #[expect(clippy::too_many_arguments)] pattern already in use. Cycle 2 extended register_alias symmetrically per decisions/06 line 109-110 intent.
• Update ALL 17 caller sites (3 user_types.rs + 6 builtin_types.rs + 8 registry/types/tests.rs per caller blast radius above) to pass the new burden: Option<UserBurdenSpec> argument. builtin_types.rs sites pass burden derived from BURDEN_TABLE entry for the corresponding builtin TypeId; test sites pass None unless test specifically exercises burden semantics. ACTUAL: 18 sites (plan undercount by 1 — tests.rs:158 register_alias caller); see HISTORY 2026-05-14 §01.3 cycle 2.
• At user_types.rs:70/135/150 integration sites, compute UserBurdenSpec from the parsed declaration via Triviality-based partition (corrected to Tag-first ternary partition per decisions/06 §Phase Boundary Cure — see HISTORY 2026-05-14 §01.3 cycle 3 for prose-drift cure note). Helpers landed in new sibling check/registration/burden_compute.rs per BLOAT-cap discipline.
  • Struct: walk fields; each field’s Triviality (per compiler_repo/compiler/ori_types/src/triviality/mod.rs::classify_triviality(field_idx, pool)) determines owned_fields (NonTrivial/Unknown) vs borrowed_fields (Trivial) partition.
  • Sum: walk variants; per-variant transfers_on_match populated from variant payload field shape using same Triviality partition.
  • Newtype type N = Existing: inherit UserBurdenSpec from Existing if user-defined (recursive type_registry.burden(existing_idx) lookup), OR construct from BURDEN_TABLE.lookup_builtin(<existing-typeid>) if Existing is builtin. Newtype identity is nominal per types.md §TI-5; burden is structural — inheritance is mechanical. Recursive types use cycle-detection identical to triviality::classify_recursive cycle handling (triviality/mod.rs:55,63); deferred to §02.
• TypeRegistry::burden(idx: Idx) -> Option<&UserBurdenSpec> — lookup tied to TypeRegistry lifetime; impl body is self.types_by_idx.get(&idx).and_then(|entry| entry.burden.as_ref()) per decisions/06-burden-field-placement.md §Lookup API. Carries #[must_use] + #[inline] + concept-only /// doc (no wrapper-path citation per impl-hygiene.md §PUBLIC_LEAK:wrapper-path-reference).
• Tests authored at compiler_repo/compiler/ori_types/src/registry/types/tests.rs (reuses existing test_name/test_span fixtures; visibility promotion mod registration → pub(crate) + compute_*_burden → pub(crate) for cross-module test access). Driver-override vs original registry/burden/tests.rs path — see HISTORY 2026-05-14 §01.3 cycle 5. Matrix: 9 integration cells through TypeRegistry::register_* + TypeRegistry::burden(idx):
  • Register a user struct with one heap field (str, Tag::Str → owned-heap per decisions/06 Tag-first ternary partition) + one scalar field (int, Tag::Int → omit) — verify burden(idx).unwrap().owned_fields.len() == 1 and borrowed_fields.len() == 0 (scalar int omitted from BOTH partitions per Round-5 codex-F1 LEAK:scattered-knowledge cure).
  • Register a user sum with two variants — verify variant_burdens.len() == 2 and per-variant transfers_on_match partitions correctly.
  • Register a newtype around int — verify burden(idx).is_none() (newtype around Value-trait primitive has empty burden).
  • Register a newtype around str — verify burden(idx).unwrap().owned_fields.len() == 1 (inherits underlying str burden).
  • Phase-boundary regression: verify compiler_repo/compiler/ori_types/Cargo.toml does NOT depend on ori_arc (would surface in cargo c -p ori_types); confirm ori_types::triviality::Triviality is the burden-partition input vs ori_arc::ArcClass.

01.4 Unified lookup_burden helper at Phase 5 emission boundary

File(s): compiler_repo/compiler/ori_arc/src/lower/burden_lookup.rs (new)

Tasks:

• pub fn lookup_burden(ty: TypeRef, type_registry: &TypeRegistry) -> Option<BurdenRef<'_>> shipped at compiler_repo/compiler/ori_arc/src/lower/burden_lookup.rs — dispatches on TypeRef variant: Builtin(type_id) → BurdenRegistry::lookup_builtin(type_id) returning BurdenRef::Builtin(&'static BuiltinBurdenSpec); User(idx) → type_registry.burden(idx) returning BurdenRef::User(&'a UserBurdenSpec). Carries debug_assert!(idx.raw() < TYPE_PARAM_E_RAW, ...) per §01.H NOTE:tuple-namespace-discipline anchor.
• BurdenRef<'a> enum (defined in §01.1’s ori_arc::lower::burden module) carries the two variants; the Burden trait gives Phase 5 emission a uniform consumption surface. Re-exported at ori_arc::lower::lookup_burden for downstream consumers.
• Phase 5 emission (consumer in §03) consumes BurdenRef via Burden trait methods uniformly; user-vs-builtin distinction does NOT leak into Phase 5 logic. Structural surface ready; consumer wiring lives in §03 per phase-boundary discipline.
• Tests at compiler_repo/compiler/ori_arc/src/lower/burden_lookup/tests.rs: 9 cells covering lookup_builtin_int/str/bool (lifetime-free BurdenRef::Builtin); lookup_user_returns_registry_borrowed_burden_ref (tied to TypeRegistry); lookup_user_unregistered_returns_none + lookup_user_registered_without_burden_returns_none (None paths); dispatch_parity_owned_fields_across_partition + dispatch_parity_borrowed_fields_zero_arity (Burden trait method dispatch parity); lookup_user_idx_partition_does_not_query_builtin_table (TypeRef-variant partition discipline regardless of raw value). Cures §01.H GAP:cross-feature-interaction-coverage anchor (Burden × ARC IR boundary integration via real TypeRegistry::register_struct + lookup_burden round-trip).
• TPR checkpoint — /tpr-review covering 01.1-01.5 (registry split correctness, purity boundary preservation, lookup helper shape, FFI contract, schema match with proposal).

01.5 FFI exclusion contract — empty vs annotated BurdenSpec

File(s): compiler_repo/compiler/ori_registry/src/burden/ffi.rs (new) + tests at compiler_repo/compiler/ori_arc/src/lower/burden_lookup/tests.rs

Mission (per blind-spot codex #3): Preserve the FFI exclusion contract from proposal:643-645 (Q12) at the registry boundary. The contract is bidirectional:

• Unannotated FFI / opaque types (CPtr, JsValue, JsPromise<T>, extern "c" from "lib" { ... } types WITHOUT #free annotation per ori-syntax.md §Deep FFI) get empty BuiltinBurdenSpec — sound ONLY for caller-managed lifetime (Ori does NOT decrement; FFI consumer owns cleanup).
• Annotated FFI types (extern "c" from "lib" #free(fn) { ... }) get an explicit UserBurdenSpec with user_drop: Some(FnSym) pointing at the user-supplied free function.

§00 clause 8 (decisions/00-rl31-burden-aware-design.md SUFFICIENT-Noalias Rule clause 8) explicitly excludes empty-BuiltinBurdenSpec FFI parameters from the RL-31 noalias proof — empty BurdenSpec ≠ empty reachable memory.

Tasks:

• Document the empty-vs-annotated split in compiler_repo/compiler/ori_registry/src/burden/ffi.rs (module-level //! rustdoc cites proposal:643-645).
• §01.2 builtin templates for CPtr, JsValue, JsPromise<T> emit empty BuiltinBurdenSpec (no fields, no variants, self_heap_alloc: false, compiled_drop: None, user_drop: None).
• §01.5(a) Extend ExternDef/ExternBlock AST per compiler_repo/compiler/ori_ir/src/ast/items/extern_def.rs (re-exports at compiler_repo/compiler/ori_ir/src/ast/items/mod.rs:11) to carry parsed #free(fn) attribute.
• §01.5(b) Parser support for #free(<symbol>) annotation in extern blocks per compiler_repo/compiler/ori_parse/src/grammar/item/extern_def.rs.
• §01.5(c) NEW register_extern_burden(extern_block: &ExternBlock, type_registry: &mut TypeRegistry) helper in compiler_repo/compiler/ori_types/src/check/registration/extern_types.rs (new file) invoked alongside register_struct/register_enum/register_newtype from registration/mod.rs.
• §01.5(d) When #free(fn) present, registration computes UserBurdenSpec per decisions/05-burdenspec-storage-model.md §UserBurdenSpec (user_drop: Some(<FnSym for fn>), all field/variant lists empty) and stores on extern-type’s TypeEntry.burden slot per decisions/06-burden-field-placement.md.
• §01.5(e) When #free absent, registration leaves TypeEntry.burden = None; lookup_burden(User(idx)) returns None for absent-burden user types (preserving the lookup_user_registered_without_burden_returns_none test contract from §01.4). §05 consumers fall back to BurdenRef::Builtin(&EMPTY_BURDEN_SPEC) (static all-empty BuiltinBurdenSpec, exposed via pub use ffi::EMPTY_BURDEN_SPEC) by direct construction at the noalias-proof site — semantically identical to builtin opaque types (CPtr/JsValue) per proposal:643-645 (caller-managed lifetime; Ori emits no drops). Structural contract (owned_fields().is_empty() + user_drop().is_none()) preserved across both routes for §05’s RL-31 noalias-proof site. Round-2 codex-F2 + Round-4 opencode-F1 cures both honored.
• Tests — structural (cures blind-spot codex Round 5 noalias scope-bleed finding — STRUCTURAL pin lives here, BEHAVIORAL noalias-proof pin lives in §05):
  • Test 1 (unannotated FFI is empty for drop — STRUCTURAL): register a CPtr use site; verify lookup_burden(CPtr, registry) returns BurdenRef::Builtin(<empty>); verify Burden::owned_fields() returns &[]; verify Burden::user_drop() returns None. This is a STRUCTURAL test of the burden-classification surface only.
  • Test 2 (annotated FFI has explicit burden — STRUCTURAL): register an extern block extern "c" from "libsqlite" #free(sqlite3_close) { type DbHandle }; verify lookup_burden(DbHandle, registry) returns BurdenRef::User(<spec>) with user_drop == Some(sqlite3_close) and owned_fields.is_empty().
  • Test 3 (parser-level): cargo t -p ori_parse extern_free_annotation covers #free(fn) parses correctly into ExternBlock’s new attribute slot; rejects malformed shapes (#free, #free(), #free(123)).
  • Test 4 (typeck-level): cargo stf extern_free_annotation covers Ori spec test invoking register_extern_burden.
  • NOTE: §05’s RL-31 burden-aware noalias-rejection BEHAVIORAL pin (rejecting empty-BuiltinBurdenSpec FFI parameters per decisions/00-rl31-burden-aware-design.md clause 8) is OWNED BY §05 per 00-overview.md:45. §01.5 success_criteria depends ONLY on the structural anchor. Cross-link: §05 declares depends_on: ["01"] (already wired) and consumes the §01.5 structural artifact via lookup_burden(...).owned_fields().is_empty() query at the noalias-proof site.
• Negative pin (compile_fail): extern "c" type passed to Owned-expecting function WITHOUT #free annotation emits diagnostic E2042 (next-available code per compiler_repo/compiler/ori_diagnostic/src/errors/mod.rs enumeration). E2042 allocation: see §01.5 References — decisions/06-burden-field-placement.md §Diagnostic for full procedure (allocation surface, errors/E2042.md markdown, errors/mod.rs:82+ enum row); blocker-routing per routing.md §2 inline-bug discipline.

Section close-out — §01.5 architectural notes

• §01.5(e) — EMPTY_BURDEN_SPEC is exposed via pub use in ori_registry::burden::mod; §01.4 lookup_burden retains None-on-missing semantics for User-with-no-burden (preserves §01.4-shipped tests). §05 consumers should treat Option<BurdenRef>::None (or BurdenRef::Builtin(&EMPTY_BURDEN_SPEC) constructed directly) as the empty-FFI sentinel; both routes yield owned_fields().is_empty() == true and user_drop().is_none() == true per the §00 clause 8 contract.

01.R Third Party Review Findings

Per /tpr-review §10 cap-exit filing protocol: only unresolved actionable anchors live here; round-by-round narrative + per-finding cure transcripts live in commit messages (commits 307cd26, a7f0422, 1c9a398) + review_pipeline marker per impl-hygiene.md §No Prose in Authored .md + state-discipline.md §7 HISTORY-block conventions.

Unresolved actionable anchors:

If §02 implementation surfaces a need for separate key_burden + value_burden slots on BuiltinBurdenSpec, amend decisions/05 Type Schemas + add §02 amendment ticket per routing.md §6 discovery insertion.
• (deferred-with-anchor: §01.N close-out item — “§05 cross-link verification (transitive vs direct edge)”) [TPR-01-R5-codex-F3][High PLAN_COHERENCE_DRIFT] §01.N close-out item §05 cross-link verification at section-01-burden-registry.md:284 says “confirm §05’s depends_on: includes “01"" but §05 frontmatter declares depends_on: ["04B"] (transitive via §04B → §01). Disposition: at §01.N close-out, EITHER (a) update §01.N item to verify the transitive edge §05 → §04B → §01 per the §04 prototype-gate→implementation chain, OR (b) add direct §05 → §01 edge to §05 frontmatter depends_on: ["01", "04B"] if §05 directly consumes §01.5’s lookup_burden artifact (read decisions/05+06 + §05 body to determine which is canonical at §01.N close time). Per §01.5 landing: §05 DOES directly consume §01.5’s structural surface (lookup_burden(...).owned_fields().is_empty() + BurdenRef::Builtin(&EMPTY_BURDEN_SPEC)); option (b) (direct edge) is favored at §01.N close.

Either path consistent; §01.4 + §01.5 implementation did not surface the inconsistency because §01.5’s structural surface (BurdenRef::Builtin(&EMPTY_BURDEN_SPEC) + Burden::owned_fields()/Burden::user_drop()) does not exercise nested-view consumers — those activate at §05.

Section-close TPR Round 1 (2026-05-14)

Final full-section TPR per §01.N item. Reviewer set: codex + gemini + opencode (Opus 4.7 parent). Adjudicator (fork-context Opus, /independent-review round-adjudicator mode) verdict: 4 actionable + 1 refuted.

• [TPR-01-CLOSE-R1-codex-F1][Critical PUBLIC_LEAK:wrapper-rule-reference] burden_compute.rs doc comments cited wrapper-private rule paths (types.md §TL-9, compiler.md §Phase-Specific Purity, typeck.md §PC-2). Cured: stripped 3 wrapper-rule references across module doc (//!) + FieldClass doc + body comment (line 108); concept words preserved per impl-hygiene.md §C-B13.
• [TPR-01-CLOSE-R1-codex-F2][Critical GAP:borrowed-field-partition] REFUTED. classify_field_for_burden _ => match classify_triviality(...) lacks explicit Tag::Borrowed arm. Tag::Borrowed handling deferred per target-only design (Tag::Borrowed target-only; cycle-3 history documents FieldClass::Borrowed variant removed deliberately per CLAUDE.md ban on hypothetical-future design). Not a defect.
• [TPR-01-CLOSE-R1-codex-F3][Major GAP:ffi-registration-and-diagnostic] register_extern_block_burden body is stub pending extern-type AST surface. Reconciled with existing (deferred-with-anchor: §02+ extern-type-AST consumer ships type-declaration AST nodes) at §01.N line 641 — the helper signature + tests + E2042 diagnostic are shipped; consumer activation awaits grammar extension. No further code change.
• [TPR-01-CLOSE-R1-opencode-F1][Major LEAK:scattered-knowledge] burden_lookup.rs:20 mirrored u32::MAX - 1 as literal TYPE_PARAM_E_RAW. Cured: imported pub const TYPE_PARAM_E from ori_registry::burden::table (was pub all along; previous comment claim that source was private was wrong) and derived raw via TYPE_PARAM_E.get().get() — single SSOT preserved.
• [TPR-01-CLOSE-R1-opencode-F2][Minor NOTE] registry/burden.rs:9-12 carried stale #![allow(dead_code)] whose stated condition (“when TypeEntry.burden lands”) was met at §01.3. Cured: attribute removed; all types consumed by burden_compute + burden_lookup tests + Burden trait impl.

Gates: cargo c -p ori_arc -p ori_types --all-targets clean post-fixes.

Section-close TPR Round 2 (2026-05-14)

Round 2 verification of round 1 fixes. Adjudicator verdict: 1 NEW actionable + 1 NOTE + 2 re-raises (already classified).

• [TPR-01-CLOSE-R2-codex-F1][High GAP] Re-raise of round 1 codex-F2 (Tag::Borrowed partition). Classification unchanged: REFUTED — target-only design per documented cycle-3 history; FieldClass::Borrowed deliberately removed per CLAUDE.md ban on hypothetical-future design. Meta-duplicate per §6 prior-round-duplicate clause.
• [TPR-01-CLOSE-R2-codex-F2][High GAP] Re-raise of round 1 codex-F3 (extern-type registration). Classification unchanged: RECONCILED via §01.N line 641 deferred-with-anchor for §02+ extern-type-AST consumer; helper signatures + E2042 + parser surface all shipped at §01.5; consumer activation awaits grammar extension. Meta-duplicate per §6 prior-round-duplicate clause.
• [TPR-01-CLOSE-R2-opencode-F1][Major PLAN_COHERENCE_DRIFT] §01.5(e) checkbox text claimed lookup_burden returns BurdenRef::Builtin(&EMPTY_BURDEN_SPEC) for empty-burden case, but implementation returns None (dual-route documented in 01.5-note amendment). Cured: rewrote checkbox text inline to reflect the dual route — lookup_burden(User(idx)) returns None; §05 consumers fall back to BurdenRef::Builtin(&EMPTY_BURDEN_SPEC) by direct construction at the noalias-proof site. Structural contract preserved across both routes.
• [TPR-01-CLOSE-R2-opencode-F2][informational NOTE] self_heap_alloc: true in compute_struct_burden correctness flag for current ARC-managed user types. Future-sensitivity point for inline type support where structs may be stack-allocated despite non-trivial fields. Preserved as informational; addressed when inline-type support ships.

Round 2 net classification: all findings either refuted, deferred-with-anchor, or meta-duplicate (prior-round). meta_only_streak: 0 → 1.

Section-close TPR Round 3 (2026-05-14)

Round 3 surfaced one NEW Critical PUBLIC_LEAK plus 2 re-raises. Comprehensive sweep across all §01-touched compiler files identified 2 in-scope wrapper-rule references (1 codex-cited + 1 in E2042.md doc); both cured.

• [TPR-01-CLOSE-R3-codex-F1][High GAP] Re-raise of round 1/2 codex (Tag::Borrowed). Classification unchanged: REFUTED. Meta-duplicate.
• [TPR-01-CLOSE-R3-codex-F2][High GAP] Re-raise of round 1/2 codex (extern-type registration). Classification unchanged: RECONCILED via §01.N deferred-anchor. Meta-duplicate.
• [TPR-01-CLOSE-R3-codex-F3][Critical PUBLIC_LEAK:wrapper-rule-reference] ori_registry/src/burden/ffi.rs:7 cited ori-syntax.md §Deep FFI in module doc. Cured: stripped citation; concept preserved (annotation surface described inline). Also cleared adjacent leak in compiler_repo/compiler/ori_diagnostic/src/errors/E2042.md:43 (ori-syntax.md §Deep FFI → Spec: Clause 26.11 Deep FFI). Comprehensive sweep across burden-touched files confirmed zero remaining wrapper-rule citations in §01 scope.

meta_only_streak: 1 → 0 (round 3 had 1 NEW actionable). Gates: cargo c -p ori_registry -p ori_types -p ori_arc -p ori_diagnostic --all-targets clean post-fixes.

Section-close TPR Round 4 (2026-05-14)

Survivor-mode round (codex transport_failure, opencode clean verification, gemini 1 meta-duplicate).

• [TPR-01-CLOSE-R4-codex-survivor] Codex hit Tier 4.5 report-cap-exceeded + truncated whitespace report. Per §9 survivor-mode matrix: 1 failed of 3 → 2-of-3 round, proceed.
• [TPR-01-CLOSE-R4-gemini-F1][High PLAN_COHERENCE_DRIFT:deliverable-missing] Re-raise of Tag::Borrowed partition. Classification unchanged: REFUTED per target-only design (types.md §TL-9 documented). Meta-duplicate.
• [TPR-01-CLOSE-R4-opencode-clean] Verification summary: all 5 structural criteria (a)-(e) verified against actual code at cited paths. 51/51 burden tests pass; cargo c clean; plan corpus coherence clean. Zero structural defects found.

meta_only_streak: 0 → 1.

Section-close TPR Round 5 (2026-05-14) — convergence

Final round. All findings exact-duplicates of prior-round classifications.

• [TPR-01-CLOSE-R5-codex-F1][High GAP:borrowed-field-partition] Re-raise of Tag::Borrowed partition. Classification unchanged: REFUTED per target-only design. Meta-duplicate.
• [TPR-01-CLOSE-R5-codex-F2][High GAP:ffi-registration-and-diagnostic] Re-raise of extern-type registration. Classification unchanged: RECONCILED via §01.N deferred-anchor. Meta-duplicate.
• [TPR-01-CLOSE-R5-gemini-F1][Critical STRUCTURE:section-not-promoted] Re-raise of long-standing section-promotion item documented in §01.R as deferred-with-anchor (cross-round consensus from §01 dev phase). Classification unchanged: deferred-with-anchor [TPR-01-004+008+010-codex+gemini]. Meta-duplicate.
• [TPR-01-CLOSE-R5-opencode-failed] Sub-agent emitted “Waiting for Bash…” mid-invocation per tp_agent_prompt.md §Banned — sub_agent_contract_violation. Per §9 survivor-mode matrix: 1 failed of 3 → 2-of-3 round, proceed.

meta_only_streak: 1 → 2. CONVERGENCE per §5 quick-gate. Per /tpr-review §1.7: exit_reason = cap_reached_meta_only.

Section-close TPR final disposition

Total cures across 5 rounds: 5 actionable fixes (3 PUBLIC_LEAK wrapper-rule references stripped; 1 LEAK literal→SSOT import; 1 stale #![allow(dead_code)]; 1 PLAN_COHERENCE_DRIFT prose alignment). Standing items: Tag::Borrowed partition (refuted target-only) + extern-type registration (deferred-with-anchor §01.N line 641) + section-promotion (deferred-with-anchor across all rounds — runs at §01.N close per routing.md §4 Promotion mechanics).

Gates: cargo c -p ori_registry -p ori_types -p ori_arc -p ori_diagnostic --all-targets clean post-all-rounds; plan-corpus coherence clean; 51/51 burden tests pass per opencode round 4 verification.

01.H Hygiene Findings

Scope: compiler_repo/compiler/ori_registry/src/burden/ (4 files) + compiler_repo/compiler/ori_types/src/registry/burden.rs + compiler_repo/compiler/ori_arc/src/lower/burden/tests.rs — auto-scoped to §01.2 BURDEN_TABLE implementation exit from /tpr-review Round 4 clean. Third-party cross-check: codex + gemini + opencode — 11 confirmed, 4 surfaced, 1 dropped (F-010).

Findings

[PUBLIC_LEAK:wrapper-path-reference] compiler_repo/compiler/ori_types/src/registry/burden.rs:10-12 — [TP-SURFACED-codex] inline comment cites plans/aims-burden-tracking/decisions/05-burdenspec-storage-model.md — a wrapper-private path. PUBLIC_LEAK:wrapper-path-reference; Critical per impl-hygiene.md §Finding Categories. Fix: remove plans/ citation; retain concept-only form: // consumed by §01.3 TypeEntry.burden field; staging types ahead of consumer per plan ordering (NO private path). — severity: Critical — remediation: inline-fix (PUBLIC_LEAK blocks close).

[PUBLIC_LEAK:wrapper-path-reference] compiler_repo/compiler/ori_arc/src/lower/burden/mod.rs:3-4 — [TP-SURFACED-codex] cites plans/aims-burden-tracking/decisions/05-burdenspec-storage-model.md as bridge design rationale. Same PUBLIC_LEAK:wrapper-path-reference violation. Fix: replace with public-safe concept-only form citing the storage model split without private path reference. — severity: Critical — remediation: inline-fix (PUBLIC_LEAK blocks close).

[COMMENT_HYGIENE_DRIFT:inaccurate-comment] compiler_repo/compiler/ori_arc/src/lower/burden/mod.rs:8 — [TP-SURFACED-codex] module doc claims “no intermediate Vec materialization”; code-verified: VariantBurdenView owns Vec<TransferRuleView> and Vec<OwnedFieldView>; view_from_builtin_variant() + view_from_user_variant() both .collect() into these Vecs. Inaccurate comment is load-bearing (consumer expectations about allocation behavior). Per impl-hygiene.md §C-B12: inaccurate comments are Critical by default. Fix: amend module doc line 8 — remove the incorrect no-Vec claim; replace with accurate: “Scalar field views avoid intermediate allocation; VariantBurdenView collects its transfers_on_match and retained_owned into Vec<_> on each call.” — severity: Critical — canonical home: compiler_repo/compiler/ori_arc/src/lower/burden/mod.rs:8 — remediation: inline-fix per impl-hygiene.md §Findings Disposition (inaccurate-comment must be corrected in same session).

[GAP:test-coverage-gap] compiler_repo/compiler/ori_registry/src/burden/table/tests.rs:159-194 — burden_table_has_expected_entry_count() asserts BURDEN_TABLE.len() == 17 (positive pin) and out_of_scope_builtins_return_none() pins 6 deferred types, but missing: a TypeTag-iteration exhaustive-match test asserting every TypeTag variant is classified as either BURDEN_TABLE entry or composition-layer deferred. Adding a new TypeTag without a BURDEN_TABLE entry returns None silently — no test failure. INVERTED-TDD risk for future TypeTag additions. matrix_dimension: type × dispatch-classification. — severity: Major — remediation: inline-fix at §01.R — add exhaustive-match completeness test before §01.2 close. Anchor: §01.R Findings block, routing.md §3 case (a) (blocker on close).

[GAP:matrix-test-coverage] compiler_repo/compiler/ori_arc/src/lower/burden/tests.rs:60-194 — matrix coverage gaps per tests.md §Matrix Testing Rule: (a) empty burden (BurdenRef::Builtin EMPTY) not tested for owned_fields/borrowed_fields/variant_burdens iterator behavior; (b) arity-0 + arity-2+ field parity missing (all tests use 1-field/1-variant); (c) iterator exhaustion semantics (Box consumed fully vs truncated); (d) empty Cow boundary. matrix_dimension: BurdenRef variant × field-count × iterator-semantics. — severity: Major — remediation: inline-fix at §01.R — add 3 test cells: (1) test_burden_ref_empty_owned_fields_returns_empty_iterator, (2) test_burden_ref_multi_field_parity (3-field), (3) test_burden_ref_variant_burdens_zero_arity. Anchor: §01.R.

[STRUCTURE:naming-convention-clarity] compiler_repo/compiler/ori_types/src/registry/burden.rs:22-58 — heap-backed types use Owned suffix (OwnedFieldOwned, BorrowedFieldOwned, TransferRuleOwned, VariantBurdenOwned) which collides semantically with AIMS lattice dimension Access::Owned (aims-rules.md §1.1). Readers tracing burden code through ARC integration hit the semantic overlap. User prefix already established (UserBurdenSpec). — severity: Major — fix: rename OwnedFieldOwned → UserOwnedField, BorrowedFieldOwned → UserBorrowedField, TransferRuleOwned → UserTransferRule, VariantBurdenOwned → UserVariantBurden. 4-type rename + import-site updates in same crate. — remediation: inline-fix per impl-hygiene.md §NAMING (‘rename in same pass; never deferred’). Anchor: §01.R Findings.

[GAP:drift-detection-mechanism] compiler_repo/compiler/ori_registry/src/burden/table/tests.rs:196-245 — type_ids_align_with_typetag_discriminants() guards TypeId derivation via exhaustive match but NOT BURDEN_TABLE entry presence. A new TypeTag variant (e.g., TypeTag::SetCow) can be added with (a) TYPE_ID constant (caught by exhaustive match) but (b) no BURDEN_TABLE entry (NOT caught; lookup_builtin returns None silently). — severity: Major — fix: add type_tag_burden_classification_complete() test using exhaustive match classifying each TypeTag::* as BurdenTableEntry(expected_template) or CompositionDeferred — compiler-enforced drift detection. ~40 lines including exhaustive match arms. — canonical home: compiler_repo/compiler/ori_registry/src/burden/table/tests.rs (extension of existing alignment test) — remediation: inline-fix at §01.R.

[STRUCTURE:registry-md-sync-gap] .claude/rules/registry.md — §Adding a New Type enumerates 10 steps; no step mentions BURDEN_TABLE or burden module sync. §01.1 shipped but registry.md is out of sync: contributor following registry.md to add a new type will miss the burden sync point, producing DRIFT the moment §01.2-§01.5 ship. — severity: Major — fix: add step 7.5 to registry.md §Adding a New Type: “Add (TYPE_ID_NAME, BuiltinBurdenSpec { ... }) entry to BURDEN_TABLE in burden/table.rs OR document deferral to composition layer.” Also update §Invariants: “Burden table entries align with TypeTag discriminants (via burden_type_id()).” — canonical home: .claude/rules/registry.md §Adding a New Type — remediation: inline-fix per impl-hygiene.md §Findings Disposition — doc sync is §01.1 close-out scope. Also auto-triggered by sync-claude when registry.md is modified.

[STRUCTURE:rationale-prose] compiler_repo/compiler/ori_registry/src/burden/mod.rs:1-29 — module rustdoc carries 29 lines of explanatory prose (Purity Contract + Cross-Crate ID Note). Per impl-hygiene.md §C-B4 module doc hard cap 12 non-blank lines. Current: 21 non-blank lines. — severity: Minor — fix: compact to ≤12 lines keeping mechanical invariant statements as bullets; defer rationale to decisions/05. — remediation: inline-fix per impl-hygiene.md §Findings Disposition.

[STRUCTURE:rationale-prose] compiler_repo/compiler/ori_registry/src/burden/table.rs:1-23 — table module doc explains Template Categories + Composition Layer in 4+ paragraphs (23 non-blank lines), exceeding §C-B4 hard cap 12 for //!. — severity: Minor — fix: compact to bullet list naming the four template categories; cite decisions/05 for rationale. — remediation: inline-fix per impl-hygiene.md §Findings Disposition.

[STRUCTURE:dead-code-rationale-clarity] compiler_repo/compiler/ori_types/src/registry/burden.rs:10-16 — #![allow(dead_code, reason = '...')] block with inline // comment above (lines 10-12) duplicating the reason= field content. Two information surfaces saying the same thing in 6 lines. Per impl-hygiene.md §C-B4 (inline-narrative duplication). — severity: Minor — fix: delete lines 10-12 (// inline comment); keep only #![allow(dead_code, reason = '...')] block. reason= is the canonical surface per impl-hygiene.md §Lint Discipline. — remediation: inline-fix (litter-pickup; same-file edit).

[STRUCTURE:macro-internal-unreachable] compiler_repo/compiler/ori_registry/src/burden/table.rs:32-48 — macro_rules! tid! and macro_rules! vid! use unreachable!() without message arguments. Per impl-hygiene.md §Panic & Assertion: “Include context message. Never panic!() for impossible states.” tid!(0) would produce unreachable!() compile-time panic with no explanation. — severity: Minor — fix: unreachable!("tid!() requires nonzero literal") and unreachable!("vid!() requires nonzero literal"). — remediation: inline-fix per impl-hygiene.md §Panic & Assertion.

[STRUCTURE:test-naming-shape] compiler_repo/compiler/ori_registry/src/burden/tests.rs:5-79 — test names don’t follow <subject>_<scenario>_<expected> shape per impl-hygiene.md §Test Function Naming: test_owned_field_struct_is_copy → test_owned_field_implements_copy_trait; test_transfer_kind_variants → test_transfer_kind_has_two_distinct_variants; test_const_construction_with_data → test_builtin_burden_spec_const_construction_with_non_empty_data. — severity: Minor — remediation: inline-fix per impl-hygiene.md §Test Function Naming + §NAMING (‘rename in same pass; never deferred’). Names are local to test file (no callers).

[STRUCTURE:cross-crate-coupling-clarity] compiler_repo/compiler/ori_registry/src/burden/mod.rs:12-18 — module doc cites ori_arc::lower::burden_lookup as the boundary translation site, but this function does NOT exist yet (§01.4 will create it). Forward-reference documentation risks name rot if §01.4 names the function differently. — severity: Minor — fix: replace specific function name with abstract location: “at the ori_arc::lower boundary in the burden-lookup helper”. Anchor in §01.4 plan checkbox for the concrete name. — remediation: inline-fix per impl-hygiene.md §Findings Disposition (documentation precision).

[STRUCTURE:spec-citation-missing] compiler_repo/compiler/ori_registry/src/burden/mod.rs:1-19 — module doc explains the architectural pattern but does not cite the spec clause establishing the burden-spec model. Per impl-hygiene.md §C-A4: spec citation required on code implementing AIMS pre-pass rules. — severity: Minor — fix: add // Spec: Annex E §AIMS — burden specs are typed pre-pass input feeding the lattice-driven analysis. — remediation: inline-fix per impl-hygiene.md §C-A4. Annex E §AIMS is the PUBLIC_LEAK-safe form per aims-rules.md public algorithmic SSOT reference.

[COMMENT_HYGIENE_DRIFT:decorative] compiler_repo/compiler/ori_arc/src/lower/burden/mod.rs:92 — [TP-SURFACED-codex] line 92: // === View construction helpers === — decorative banner using === separators. Per impl-hygiene.md §C-B9 decorative banners are banned. Code-verified at line 92. — severity: Minor — fix: replace with plain // View construction helpers (C-A8 section label form). — remediation: inline-fix per impl-hygiene.md §Findings Disposition (litter-pickup; same-file edit).

[STRUCTURE:module-path-coupling-via-test] compiler_repo/compiler/ori_arc/src/lower/burden/tests.rs:5-12 — 14 cross-crate type imports (9 from ori_registry + 4 from ori_types + 1 ori_types::Idx). Wide import surface creates brittle surface for refactors. Asymmetry signals test also exercises cross-crate sync beyond stated purpose. — severity: Minor — fix (optional): group imports with explicit module comments: // Builtin storage shapes (ori_registry): / // User storage shapes (ori_types): / // Bridge surface (local):. Cosmetic improvement, not structural change. — remediation: NOTE-class; low priority.

[GAP:cross-feature-interaction-coverage] compiler_repo/compiler/ori_arc/src/lower/burden/tests.rs (entire file) — burden × ARC IR integration tests missing (no instance of BurdenRef participating in ArcInstr; no RC emission tests; no realization phase tests). Per tests.md §Interaction Testing. Deferred-with-anchor: §01.4 plan checkbox — Burden × ARC IR integration tests when lookup_burden helper ships. — severity: Major — remediation: deferred-with-anchor to §01.4 per impl-hygiene.md §Findings Disposition. Dependency on §01.4 lookup_burden ship satisfies CLAUDE.md §ALL Deferrals MUST Have Implementation Anchors case (1).

[GAP:burden-spec-decision-log-thinness] plans/aims-burden-tracking/decisions/05-burdenspec-storage-model.md — cited 3+ times from compiler_repo source; per Phase 1 planned_covered_findings TPR-01-R5-codex-F4: decisions/05 nested-view lifetime story internally inconsistent with storage model. Reconfirmation finding — not new; anchored for §01.4 per existing §01.R TPR-01-R5-codex-F4 anchor. — severity: Major — remediation: deferred-with-anchor to §01.4 (existing anchor). PRE-PLANNED finding; this entry serves as continuity record for Phase 4.

[STRUCTURE:burden-trait-vs-burdenref-relationship] compiler_repo/compiler/ori_arc/src/lower/burden/mod.rs:72-90, 168-221 — trait Burden has only one implementor (BurdenRef<'_>). Trait abstraction is currently degenerate — phase-5 consumers either call burden_ref.method() or could match on BurdenRef directly. The Box<dyn Burden> path adds boxing overhead. Two options: (a) keep for §02 extensibility (Composed variant); (b) inline per YAGNI. decisions/05 should clarify. NOT inline-fixable without aligning with §02 plan direction. — severity: Minor — remediation: deferred-with-anchor to decisions/05 amendment review at §02 entry per existing §01.R TPR-01-R5-codex-F2 anchor.

[WASTE:boxed-iterator-cold-path] compiler_repo/compiler/ori_arc/src/lower/burden/mod.rs:72-80 — Burden trait returns Box<dyn Iterator<Item = OwnedFieldView<'a>> + 'a> for field/variant methods. Heap allocation per lookup. ARC lowering is warm path; boxing every burden iteration may accumulate. Mitigation: single small allocation per call (typically 16-32 bytes); iteration body bounded (≤ field count per type, usually < 10). Architecturally-correct choice given heterogeneous storage shapes (decisions/05). Alternative generic Burden<S: BurdenStorage> would cause monomorphization explosion. NOTE-class trade-off. — severity: Informational — remediation: NOTE — acceptable trade-off with design-log citation (decisions/05). Per impl-hygiene.md §Findings Disposition NOTE class: documented + non-blocking.

[NOTE:tuple-namespace-discipline] compiler_repo/compiler/ori_registry/src/burden/table.rs:110-111 — TYPE_PARAM_T = tid!(u32::MAX), TYPE_PARAM_E = tid!(u32::MAX - 1). Boundary-translation layer at §01.4 MUST reject ori_ir TypeIds where raw+1 collides with sentinel space. At u32::MAX-2 → u32::MAX-1 = TYPE_PARAM_E. NOT inline-fixable today (consumer is §01.4). — severity: Informational — remediation: deferred-with-anchor to §01.4 per impl-hygiene.md §Findings Disposition. Anchor: §01.4 lookup_burden helper implementation checkbox — add debug_assert!(idx.raw() + 1 < TYPE_PARAM_E.get().get(), "user type pool exhausted into TYPE_PARAM sentinel space").

[NOTE:naming-rationale-context] compiler_repo/compiler/ori_arc/src/lower/burden/mod.rs:85-90 — BurdenRef<'a> enum clearly separates two storage modes. Future additions risk drift if a new axis appears in BuiltinBurdenSpec or UserBurdenSpec but not in BurdenRef’s view types. Anchor candidate at §01.3 (when TypeEntry.burden ships, the sync-point list is needed). — severity: Informational — remediation: NOTE — drift-prevention scaffolding. Add 5-bullet “Burden Schema Sync Points” to module doc or decisions/05 at §01.3 implementation.

[NOTE:registry-purity-invariant-preserved] compiler_repo/compiler/ori_registry/src/burden/mod.rs:1-147 — POSITIVE FINDING: burden/mod.rs preserves all registry.md §Invariants: zero new external deps (only core::num::NonZeroU32); no heap types; no unsafe; no &mut in public API; all data const-constructible; BuiltinBurdenSpec ≤ 64 bytes compile-time gate; NonZeroU32 newtypes yield niche-optimized Option<TypeId> (8 → 4 bytes). — severity: Informational — remediation: NOTE — invariant preserved; worth recording in §01.R HISTORY as ‘invariant preserved’ anchor for future reviewers.

[NOTE:size-assertion-test-vs-rust] compiler_repo/compiler/ori_registry/src/burden/tests.rs:5-10 — test_builtin_burden_spec_size_bounded() asserts size ≤64 at runtime; mod.rs:141-143 already gates this at compile time. Test is intentionally redundant for test-output visibility. Acceptable per impl-hygiene.md §NOTE classification with explicit comment in tests.rs:7-8. — severity: Informational — remediation: NOTE — acceptable duplication with explicit documentation.

[WASTE:vec-collect-in-trait-impl-test] compiler_repo/compiler/ori_arc/src/lower/burden/tests.rs:80-94, 115-118, 176-178 — test bodies .collect::<Vec<_>>() then assert on length + element shape. Acceptable in tests. Production code consuming Burden trait would iterate without collect. Not a hot-path concern (test code). — severity: Informational — remediation: NOTE — observational; no action needed.

[NOTE:context-bloat-test-fixture] compiler_repo/compiler/ori_arc/src/lower/burden/tests.rs:14-58 — 45 lines of fixture setup (23% of 195-line file). Acceptable inline for focused test file. Optional: extract into mod helpers { ... } at top of file for visual grouping. — severity: Minor — remediation: NOTE — optional cosmetic grouping.

[NOTE:asymmetric-test-coverage-builtin-vs-user] compiler_repo/compiler/ori_arc/src/lower/burden/tests.rs (entire file) — BUILTIN_SPEC constructed as const (file-scope); user spec via fn make_user_spec() (runtime fixture). Asymmetry reflects storage-model difference (builtin = const static, user = heap Vec). Two-track fixture construction makes new-cell addition asymmetric. Acceptable as-is. — severity: Minor — remediation: NOTE — observational; acceptable trade-off.

[INVERTED-TDD:ghost-test] compiler_repo/compiler/ori_types/src/check/registration/tests.rs:72 — [TP-CONFIRMED-both] empty_module_registration calls register_user_types/register_traits/register_impls/register_derived_impls/register_consts on empty Module::default() with comment // These should not panic but zero assertions on post-registration state of checker. Test passes only if calls don’t panic — ghost-test per impl-hygiene.md §INVERTED-TDD:ghost-test. Fix: add assertions on empty registry state: assert_eq!(checker.type_registry().user_type_count(), 0) + analogous checks for traits, impls, derived impls, consts. — severity: Minor (downgraded from Critical per codex+opencode: smoke/crash test with explicit intent documentation; not neutering a deliverable) — tag: [TP-CONFIRMED-both] — remediation: inline-fix at §01.H.

[LEAK:swallowed-error] compiler_repo/compiler/ori_types/src/registry/traits/lookup.rs:152 — [TP-CONFIRMED-codex] find_conflicting_defaults: .unwrap_or_default() on super_traits lookup silently produces empty Vec when trait entry missing. Missing trait entry = registry contract violation (caller operating on unregistered trait Idx); returning empty Vec masks the invariant failure as “no conflicts” which is semantically wrong. Fix: match self.get_trait_by_idx(trait_idx) { Some(e) => e.super_traits.clone(), None => { debug_assert!(false, "find_conflicting_defaults called on unregistered trait_idx {trait_idx:?}"); Vec::new() } } OR change signature to Option<Vec<...>> forcing callers to handle missing-trait case explicitly. — severity: Major — tag: [TP-CONFIRMED-codex] — rule: impl-hygiene.md §LEAK:swallowed-error (lossy-fallback variant); typeck.md §TR-5 coherence at registration — remediation: inline-fix.

[PLAN_DELIVERY_DRIFT:missing_propagation] bug-tracker/plans/completed/BUG-01-002/00-overview.md — [TP-SURFACED-codex] (1) delivered_to_roadmap YAML field is literally absent from frontmatter (FIELD_ABSENT per grep — field not present, not merely empty; the prose statement “field stays empty per spec” does not satisfy delivery-drift.py which requires the field present with value []); (2) frontmatter has status: in-progress while plan body + completed/ path indicate plan is done — stale status drift. Fix: add delivered_to_roadmap: [] to frontmatter; update status: in-progress → complete. — severity: Major — tag: [TP-SURFACED-codex] (codex verified FIELD_ABSENT; gemini/opencode called false-positive without verifying field presence — LOWER trust gemini claim overridden by HIGH trust codex verification) — remediation: inline-fix.

[LEAK:swallowed-error] compiler_repo/compiler/ori_types/src/check/registration/impls.rs:312,351,51 — [TP-SURFACED-codex] 3 adjacent swallowed-error patterns in same registry-contract-masking family as HYG-01-003: (1) line 312: validate_assoc_types returns from function on missing trait entry without producing an error; (2) line 351: filter_map drops missing provider names silently; (3) line 51: maps empty trait path to '<unknown>' rather than surfacing the registry contract violation. All mask registry contract violations as silent skips. — severity: Major — tag: [TP-SURFACED-codex] (not confirmed by gemini/opencode; codex HIGH trust; spot-verify line ranges before acting) — remediation: inline-fix — each site should produce a debug_assert! or return Err/None to expose the contract violation rather than silently continuing.

01.N Completion Checklist

• BuiltinBurdenSpec + UserBurdenSpec data structures + BURDEN_TABLE templates + TypeRegistry::burden (on TypeEntry per decisions/06-burden-field-placement.md) + lookup_burden + FFI exclusion contract + new register_extern_burden helper + E2042 diagnostic all ship.
• cargo t -p ori_registry, cargo t -p ori_types, cargo t -p ori_arc, cargo t -p ori_parse, cargo t -p ori_diagnostic all green (per §01.5 fork-context dispatch verification: 314 ori_registry / 952 ori_types / 1293 ori_arc / 458 ori_parse / 120 ori_diagnostic — all passed).
• cargo c clean across all touched crates (cures cross-crate compile after register_struct/register_enum/register_newtype signature change to all 17 caller sites — verified via cargo check --workspace --lib clean at §01.5 close).
• (deferred-with-anchor: §02-§05 implementation — AIMS-burden cluster cures the 300-failure baseline; per plan mission cures_failures linkage target-only pre-JSON-v3 per feedback_plan_cures_failures_linkage) compiler_repo/test-all.sh green — full regression sweep (cures audit INTEGRITY:completion-template-gap finding requiring test-all.sh regression check). MANDATORY timeout 150s per CLAUDE.md §MANDATORY TEST TIMEOUTS: timeout 150 ./test-all.sh. Current baseline-red 300-failure cluster (148 Rust unit + 99 AOT + 48 spec interpreter + 1 LLVM crash + 44 leaks) IS the plan’s mission to cure; §01 ships the structural foundation §05 RL-31 noalias-proof site consumes. Per feedback_commit_push_bypass_flag.md: user-typed /commit-push --bypass is the authorization to land §01 work ahead of baseline cure.
• (deferred-with-anchor: §02+ extern-type-AST consumer ships type-declaration AST nodes — extern "c" #free(fn) { type DbHandle } literal is target-only syntax in current grammar) cargo stf extern_free_annotation + cargo stf extern_owned_without_free Ori spec tests green (parser/typeck-level gates per cross-cutting blind-spot finding). §01.5 ships parser-level #free(<symbol>) annotation parsing on extern blocks (7 tests pass) + register_extern_burdens helper (2 tests pass); spec-test-level activation awaits the extern-block type-declaration consumer per decisions/06-burden-field-placement.md §Diagnostic.
• Pure-const compliance verified: cargo expand -p ori_registry | rg -P '\b(String|Vec|Box|Arc|HashMap)\b' returns zero hits inside burden/ module (verified at §01.5 close).
• Phase-boundary regression check: grep -n "ori_arc" compiler_repo/compiler/ori_types/Cargo.toml returns zero hits (cures gemini-only blind-spot phase-bleeding finding — ori_types MUST NOT acquire ori_arc dep; burden partition uses ori_types::triviality SSOT).
• Diagnostic registry update verified: compiler_repo/compiler/ori_diagnostic/src/errors/E2042.md exists with imperative-suggestion fix; errors/mod.rs enumeration includes (ErrorCode::E2042, include_str!("E2042.md")) row.
• Plan annotation cleanup (per CLAUDE.md §Compiler Coding Guidelines — temporary annotations stripped at section close).
• Plan sync per protocol; mission criterion 2 checkbox flipped at 00-overview.md:76 (line drift from declared :39).
• /tpr-review passed (final, full-section, covering 01.1-01.5). Section-close TPR converged at Round 5 with meta_only_streak=2 → cap_reached_meta_only. 5 cures landed across rounds 1-3 (3 PUBLIC_LEAK + 1 LEAK→SSOT + 1 stale-allow + 1 PLAN_COHERENCE_DRIFT alignment). Standing items refuted or deferred-with-anchor per §01.R Section-close TPR Round N subsections.
• /impl-hygiene-review passed — 2026-05-17 cure cycle resolved all active Major findings. 9 of the 10 prior-batch concerns CURED INLINE: (1) 3 LEAK:swallowed-error sites in impls.rs (lines 47, 321, 371) gained debug_assert! cures with concept-only rationale comments; (2) lookup.rs:152 LEAK cured in earlier session with debug_assert! pattern; (3) COMMENT_HYGIENE_DRIFT bulk-strip complete (final 2 BUG-01-002 source-comment sites stripped from ori_canon/lower/collections.rs; workspace-wide grep returns zero hits); (4) STRUCTURE:naming-convention-clarity 4-type rename (*Owned → User*) complete across ori_types::registry::burden + ori_arc::lower::burden; (5) GAP:drift-detection-mechanism cured via typetag_classification_is_exhaustive_and_consistent test in ori_registry/src/burden/table/tests.rs:258; (6) GAP:matrix-test-coverage cured via 3 matrix cells at ori_arc/src/lower/burden/tests.rs:197,216,273; (7) STRUCTURE:registry-md-sync-gap cured via .claude/rules/registry.md step 11 BURDEN_TABLE sync workflow; (8) PUBLIC_LEAK + inaccurate-comment in burden/mod.rs cured. One finding (PLAN_DELIVERY_DRIFT BUG-01-002/00-overview.md) reclassified as stale-post-v5-migration: tracker-index SSOT (closed-bugs.json resolved/2026-04-29) is correct; plan.json internal status drift is a v5-migration data-consistency artifact orthogonal to tracker lifecycle (per state-discipline.md §4), deferred-with-anchor to future /improve-tooling --gap plan-internal-status-reconciliation. 2026-05-17 fresh /impl-hygiene-review pipeline (Phases 0-5 + codex+gemini+opencode 3-way cross-check) converged CLEAN: 0 Critical, 0 Major; 5 Minor BLOAT pre-existing in impls.rs (deferred-with-anchor per <!-- impl-hygiene-review 2026-05-17 --> block above); 1 warn-only COMMENT_HYGIENE_DRIFT cluster (bedding-in §0a.1); 2 [NOTE] observations (false-positive adjudication for collections.rs:74 + latent PARAM_SPRAWL on ImplMethodDef below ≥5-site threshold). Phase 1 SCOPE_EXPANSION_FAILURE:litter-pickup candidacy on collections.rs:74 REJECTED by Phase 3 (binary_search_by_key Err arm is canonical mono_dispatch lookup-miss; not a swallowed error — downstream consumer at ori_arc/lower/calls/mod.rs:49 uses equivalent .ok().map() shape). All gates clean: cargo c -p ori_types -p ori_canon --all-targets; cargo test -p ori_types --lib check::registration:: 40 passed; cargo test -p ori_registry -p ori_canon -p ori_arc --lib 1385+95+320 passed.
• Post-§01 re-validation of §00.1 worked-example-1 (§00↔§01 bidirectional contract — predecessor-side enforcement at section-00-design-validation-gate.md ### Map borrowed_fields re-validation trigger, consumer-side enforcement is THIS close-out item). Result: MATCH — no §00 Phase 0 reentry. §00.1 worked-example-1 declares {str:int} map borrowed_fields: [] with rationale “map keys/values are owned unless explicitly borrowed via projection.” §01 finalized schema at compute_struct_burden (burden_compute.rs:107-109): let borrowed: Vec<UserBorrowedField> = Vec::new() — empty until Tag::Borrowed construction ships (target-only per documented deferral; cross-rounds /tpr-review codex re-raise refuted). §01.5 FFI exclusion contract reinforces: unannotated FFI types get BuiltinBurdenSpec::EMPTY with empty owned_fields AND empty borrowed_fields; annotated FFI types get UserBurdenSpec with user_drop = Some(fn) and empty field/variant lists. Construction shapes consistent across §00.1 + §01.3 + §01.5. frozen_rule_version: v1 remains valid.
• §05 cross-link verification: confirmed section-05-phase6-lattice-rewrite.md frontmatter declares depends_on: ["01", "04B"] (direct edge to §01 + transitive via §04B per /tpr-review R5 codex-F3 deferred-anchor resolution option (b)). §05 owns RL-31 noalias-proof BEHAVIORAL test pin (per §05.3 lines 97-109): production tests for merge(a: &{str:int}, b: &[int]) and accumulate(a: {str:int}, b: [int]) emit noalias on Borrowed parameters; co-verification sweep covers KnownSafe pair elimination + PRE-style motion across RC-observable barrier + selective barrier flush. Success criterion line 138 names “RL-31 burden-aware path produces type-level disjointness proofs.” §05 consumes BurdenSpec via lookup_burden at LLVM emit time per §05.3 line 104, combining with ParamContract for strictly stronger proofs.

• 2026-05-12 — Step 5 editor pass via /review-plan autopilot. Applied 24 audit findings + 9 blind-spot findings. Specific changes: (1) split BurdenSpec into BuiltinBurdenSpec (pure-const &'static) + UserBurdenSpec (heap-backed Vec) per decisions/05-burdenspec-storage-model.md to cure memory-leak risk at gemini blind-spot #1; (2) authored TransferRule concrete field schema (source_field_path, binding_index, field_type, transfer_kind) in decisions/05-*.md §Type Schemas derived from proposal:260-282 owned-binding extraction obligations — cures codex blind-spot #2 + opencode blind-spot #1; (3) replaced fictional METHOD_TABLE/MethodRegistry prior-art references with verified BUILTIN_TYPES + TypeRegistry::register_struct/enum/newtype symbols (verified via grep against compiler_repo/compiler/ori_registry/src/defs/mod.rs:68 + ori_types/src/registry/types/mod.rs:183/218/254 + ori_types/src/registry/methods/mod.rs:19 showing MethodRegistry is a thin wrapper reserved for future trait-lookup integration) — cures gemini blind-spot #2; (4) named integration hook at user_types.rs:70/135/150 for §01.3 registration call sites — cures gemini blind-spot #3 + STRUCTURE:decision-in-implementation; (5) scoped §01 to const-template schema only with §02 owning monomorphized entries — cures codex blind-spot #1; (6) added §01.5 FFI exclusion contract subsection with empty-vs-annotated split + tests — cures codex blind-spot #3; (7) added subsection_depends_on + blocks_section_close + budget ordering primitives to frontmatter — cures opencode blind-spot #2 (STRUCTURE:ordering-implicit); (8) attempted to add post_depends_on_validation frontmatter field for the §00.1↔§01 feedback dependency — schema-rejected per scripts/plan_corpus/schemas.py PlanSectionSchema._ALLOWED_KEYS, cured by relocating the dependency declaration into §01.N close-out checkbox (line 277) + §00.3 cross-pointer per state-discipline.md §1 plan-file SSOT discipline; opencode blind-spot #3 hidden-feedback-loop cure stands via the body-anchored mechanism; (9) flipped body **Status:** Not Started to **Status:** not-started matching frontmatter — cures audit INTEGRITY:status-text-drift; (10) replaced placeholder pub struct TransferRule { /* ... */ } literal-text-placeholder with concrete schema citation pointing at decision file — satisfies feedback_review_plan_editor_must_do_mission_fit pre-/commit-push self-check (no literal-placeholder text left in body). SIZE_VIOLATION cohesion-edit: §01.4 NOT promoted to sibling section — success_criteria clause 4 ties it tightly to the §01.1-01.3 trio (BurdenRef wrapping the three storage types) per routing.md §4 independence test (it does NOT have its own deliverable that ships in isolation; it IS the integration deliverable). Tracked items grew from 30 to 32 — over the 20-cap audit threshold by design; the section’s cohesion (5 ordered subsections + R + N) is the natural decomposition and further splitting would scatter the registry SSOT. DEAD_PATH audit cohesion-edits applied via cross-section pointers to canonical paths (ori_registry/src/defs/mod.rs:68, ori_types/src/registry/types/mod.rs:183, ori_types/src/check/registration/user_types.rs:70) — original §00/§02/§03/§04 DEAD_PATH references handled in their owning sections per routing.md §1.7D bounded cohesion-edits scope.

Opus dispatch implemented ori_registry::burden, ori_types::registry::burden, ori_arc::lower::burden per decisions/05-burdenspec-storage-model.md §Type Schemas + decisions/06-burden-field-placement.md (deferred to §01.3). All 14 burden tests pass (5 ori_registry + 3 ori_types + 6 ori_arc); cargo c -p ori_registry -p ori_types -p ori_arc --all-targets clean; clippy clean; sprawl-lint clean (after struct-update-syntax refactor ..BuiltinBurdenSpec::EMPTY / ..UserBurdenSpec::default() cured PARAM_SPRAWL:zero-default-proliferation on user_drop: None). Deviations from decisions/05 documented inline: local TypeId/FnSym/VariantId newtypes in ori_registry::burden (re-exported as BurdenTypeId; ori_registry zero-deps invariant forbids ori_ir import; boundary translation deferred to §01.4); NonZeroU32 inner type for niche-optimized Option<> preserving BuiltinBurdenSpec <=64 byte size invariant; #[allow(dead_code)] on ori_types::registry::burden until §01.3 wires UserBurdenSpec into TypeEntry. Adjacent fix: ORI_DISABLE_REDUNDANT_CLEANUP env var (introduced by BUG-04-118 §05 R3 commit, missing from oric::debug_flags) registered in compiler_repo/compiler/oric/src/debug_flags.rs + documented in .claude/rules/arc.md; cures pre-existing STRUCTURE:tooling-first-bypass orphan flagged by diagnostics/check-debug-flags.sh. BLOCKER: ./test-all.sh baseline at HEAD 6dfca3a4 shows 148 Rust unit failures + 99 AOT failures (44 leaked) + 51 Ori spec interpreter failures + Ori spec LLVM backend CRASHED + 100 untracked dispositions — all pre-existing, none introduced by §01.1 (my new modules have no callers outside their own test modules). Recent commits clearly used --bypass (e.g., fix(arc): BUG-04-118 §05 R3 predates this baseline). Per feedback_never_bypass_hooks.md Claude cannot Claude-initiate --bypass; per skill-control-contract.md §Autopilot Mode this is the “hard hook-failure that re-grounding cannot resolve” termination condition. §01.1 work staged (compiler_repo: 9 files inc. debug_flags + arc.md addendum; wrapper: §01.1 subsection-status flip to complete + 4 plan-cleanup auto-resets from parallel session). SUPERSEDED 2026-05-17: “User decision required” framing reflects pre-autopilot-unified-hook-failure-clause semantics. Per current skill-control-contract.md §Autopilot Mode unified hook-failure clause, autopilot proceeds WITHOUT committing the round’s cures and WITHOUT user prompting; dirty tree cleared by parallel-session owner OR future user-typed /commit-push --bypass.

• 2026-05-13 — §01.2 BURDEN_TABLE complete; /commit-push blocked by pre-existing test-all baseline (same blocker as §01.1 above). §01.2 implementation shipped per /tpr-review 4-round convergence (Round 4 exit_reason=clean, 14 findings cured Rounds 1-3: 4 Critical PUBLIC_LEAK + 7 Major + 3 Minor) + /impl-hygiene-review (28 findings — 3 Critical + 5 Major cured inline; Minor cured or anchored to §01.H; NOTE accepted). New burden/table.rs ships BURDEN_TABLE 17 entries derived mechanically from TypeTag via burden_type_id() const fn; 23 TYPE_ID_* constants + TYPE_PARAM_T/E sentinels (u32::MAX, u32::MAX-1); BurdenRegistry::lookup_builtin #[must_use]; 14 tests including typetag_classification_is_exhaustive_and_consistent (compile-time exhaustive-match catches new TypeTag without burden classification) and type_ids_align_with_typetag_discriminants (cross-checks derivation). F-008 rename *Owned → User* across ori_types::registry::burden + ori_arc::lower::burden consumers (disambiguates from AIMS Access::Owned). F4 BuiltinBurdenSpec gains Eq+PartialEq+Hash derives. F5 TypeId/VariantId/FnSym inner-field privatization + pub const fn new() constructors per impl-hygiene §Type Discipline. Critical PUBLIC_LEAK strips across all 5 burden files (burden/mod.rs, burden/table.rs, ori_types/registry/burden.rs, ori_arc/lower/burden/mod.rs). F-020 .claude/rules/registry.md §Adding a New Type gains step 11 (BURDEN_TABLE sync workflow with InTable vs DeferredToComposition decision). §01.H Hygiene Findings block authored with 28 findings + dispositions. Gates: 940 ori_registry+ori_types+ori_arc tests pass; cargo clippy —all-targets — -D warnings clean; sprawl-lint clean (67 field-init additions, 0 violations); pure-const grep clean (zero String/Vec/Box/Arc/HashMap in burden/); PUBLIC_LEAK grep clean (zero wrapper-path refs across 7 burden files); prose-lint clean; repo-hygiene clean; CLAUDE.md within 40K cap. BLOCKER: ./test-all.sh baseline at HEAD dea49663c still red — lefthook full-check reports test failures per the same 300-failure baseline documented at the §01.1 HISTORY entry above (148 Rust unit + 99 AOT + 51 Ori spec interpreter + LLVM crash + 100 untracked dispositions; all pre-existing, none introduced by §01.2 which has zero callers outside its own test modules). Per feedback_never_bypass_hooks.md ABSOLUTE: Claude cannot Claude-initiate --bypass / --no-verify. Per skill-control-contract.md §Autopilot Mode: this is the documented “hard hook-failure that re-grounding cannot resolve” termination condition. §01.2 work staged across wrapper (.claude/rules/registry.md + plans/aims-burden-tracking/section-01-burden-registry.md) + compiler_repo (compiler/ori_arc/src/lower/burden/{mod.rs,tests.rs} + compiler/ori_registry/src/burden/{mod.rs,table.rs,table/tests.rs,tests.rs} + compiler/ori_types/src/registry/burden.rs); index intact, non-destructive per feedback_never_destructive_git.md.

Parallel-session changes in wrapper (continue-roadmap/SKILL.md, tpr-pipeline/compose_prompt.py, tests.md linter mods, plan_orchestrator/*.py, status_flip.py, tpr_review_runtime/) were unstaged in this autopilot cycle (non-destructive git reset HEAD <file>; worktree preserved); they remain modified in the worktree for the parallel session to pick up. SUPERSEDED 2026-05-17: “User decision required” framing reflects pre-autopilot-unified-hook-failure-clause semantics.

• 2026-05-14 — §01.3 /commit-push halted at hard-hook-failure (same 300-test baseline as §01.1 + §01.2). Phase A discovered 2 dirty repos (compiler_repo: 9 files §01.3 work; wrapper: 9 files §01.3 plan close + parallel-session plan-state). Phase B authored messages; commit-msg lint cured (rationale-prose-multi-paragraph → bullet-driven directive shape per skill-vocabulary.md §3).

• 2026-05-14 — §01.3 close (5-cycle /tp-dev navigator pipeline). Implementation shipped across 5 cycles via /continue-roadmap autopilot driving /tp-dev per cycle. Cycle 1 (verdict=proceed): added TypeEntry.burden: Option<UserBurdenSpec> field + init at 4 internal constructor sites; scope expanded from 1→4 files to cure cross-crate TypeEntry construction sites (output/tests.rs, llvm/type_registration/tests.rs x2) — single-file chunk_proposal undercount of cross-crate ripple. Cycle 2 (verdict=proceed): extended 4 register_* signatures + updated 18 caller sites (plan undercount by 1 — tests.rs:158 register_alias site); 4 files (mod.rs + user_types.rs + builtin_types.rs + tests.rs) — required atomic compile-clean transition; exceeds pair-cycle.md §B ≤3-file soft cap by 1 because Rust forbids signature-add without simultaneous caller update. Cycle 3 (verdict=proceed): authored 3 burden-compute helpers per decisions/06 §Phase Boundary Cure Tag-first ternary partition (NOT plan §01.3 lines 171-174 binary partition — decisions/06 is authoritative per Round-3 codex-F2; flagged as plan-prose drift); extracted helpers to sibling check/registration/burden_compute.rs (user_types.rs at 397 lines + ~110 LOC helpers would breach 500-line BLOAT cap per impl-hygiene.md §File Organization); driver-override on navigator’s inline-in-user_types.rs verdict per pair-cycle.md §D documented here. FieldClass::Borrowed variant omitted per CLAUDE.md §No Shortcuts §YAGNI (Tag::Borrowed target-only per types.md §TL-9; variant re-added when borrow-tag construction ships). Cycle 4 (verdict=redirect → path (a) verbatim): added TypeRegistry::burden(idx) per decisions/06 §Lookup API with #[must_use] + concept-only /// doc; cured pre-existing self-introduced PUBLIC_LEAK:wrapper-path-reference at TypeEntry.burden doc line 83 (Cycle 1 self-introduced) inline per CLAUDE.md §Scope Expansion litter-pickup. Cycle 5 (verdict=redirect → path (a) verbatim with driver-deviations): authored 9 integration tests through TypeRegistry::register_* + TypeRegistry::burden() lookup + 1 Cargo.toml structural regression test asserting absence of ori_arc dependency per plan §01.3 line 207 phase-boundary requirement; deviation: tests in registry/types/tests.rs (existing test_name/test_span fixtures) vs new check/registration/tests.rs, requiring visibility promotion of mod registration and 3 compute_*_burden helpers to pub(crate). ALL CYCLES: cargo c clean, cargo clippy -D warnings clean, 12 new burden tests pass. Plan-truth fixes for /sync-claude at section close: (a) plan §01.3 line 184 “17 caller sites” → 18; (b) plan §01.3 lines 171-174 binary Triviality partition prose → Tag-first ternary per decisions/06 §Phase Boundary Cure. pair_cycle_log records all 5 cycles with verdicts + redirect-consumption tracking per decisions/25 Option A.

• 2026-05-14 — §01.3 Cycle 4 redirect-consumption (path (a) apply verbatim). /tp-dev navigator Cycle 4 returned redirect on the TypeRegistry::burden(idx) lookup-method chunk with two cures: (1) add #[must_use] per impl-hygiene.md §Performance Annotations; (2) drop wrapper-private decisions/06 citation from /// doc per impl-hygiene.md §Finding Categories — PUBLIC_LEAK:wrapper-path-reference. Both cures applied verbatim in same cycle per pair-cycle.md §D path (a). Litter-pickup: pre-existing TypeEntry.burden doc at mod.rs:83 (self-introduced in Cycle 1) carried the same decisions/05 wrapper-path PUBLIC_LEAK — cured inline this cycle per CLAUDE.md §Scope Expansion litter-pickup trigger (I introduced it; I fix it).

• 2026-05-14 — /commit-push halt cross-scope skipped — failing repo: compiler_repo, owning plans: BUG-04-118 ARC closures + BUG-04-111 borrow-list-int + LLVM crash + AIMS §05+ (300-failure baseline per §01.1/§01.2/§01.3 HISTORY). Per skill-control-contract.md §Autopilot Mode cross-scope clause: §01.4 work-tree changes (compiler_repo: burden_lookup.rs + lower/mod.rs; wrapper: section-01-burden-registry.md + parallel-session plan-state) remain uncommitted; the parallel session(s) / future user /commit-push --bypass owns clearing them. Continuing to next pipeline step per Step 4 loop.

• 2026-05-14 — §01.4 deliverables shipped; checkbox 5 (TPR) deferred to section close. Authored compiler_repo/compiler/ori_arc/src/lower/burden_lookup.rs (~50 lines): pub fn lookup_burden(ty: TypeRef, type_registry: &TypeRegistry) -> Option<BurdenRef<'_>> dispatching on TypeRef variant per decisions/05 §Phase 5 consumption pattern. Builtin path → BurdenRegistry::lookup_builtin(type_id) → BurdenRef::Builtin(&'static BuiltinBurdenSpec) lifetime-free. User path → type_registry.burden(idx) → BurdenRef::User(&'a UserBurdenSpec) registry-tied. debug_assert!(idx.raw() < TYPE_PARAM_E_RAW, ...) planted per §01.H NOTE:tuple-namespace-discipline anchor — guards user pool against collision with TYPE_PARAM_T = u32::MAX / TYPE_PARAM_E = u32::MAX-1 sentinel space.

Test helper lookup_required follows ori_registry/src/burden/table/tests.rs canonical match { Some / None => panic! } pattern per tests.md §Test Hygiene workspace expect_used = "deny". Gates: cargo c -p ori_arc --all-targets clean; cargo clippy -p ori_arc --all-targets -- -D warnings clean (after 'a lifetime elision per clippy::elidable-lifetime-names); 1291 ori_arc tests pass (9 new burden_lookup + 9 pre-existing burden + 1273 unrelated, 1 ignored, 0 failures). Findings cured this cycle: §01.H GAP:cross-feature-interaction-coverage Major (deferred-with-anchor §01.4) — new tests exercise Burden × ARC IR boundary via real TypeRegistry round-trip; §01.H STRUCTURE:cross-crate-coupling-clarity Minor — new module path ori_arc::lower::burden_lookup resolves the existing forward-reference at ori_registry/src/burden/mod.rs:12-18; §01.H NOTE:tuple-namespace-discipline Informational — debug_assert anchor planted. Pre-existing cures verified: COMMENT_HYGIENE_DRIFT:inaccurate-comment Critical (already cured at §01.2 close), GAP:matrix-test-coverage Major (already cured at §01.2 with empty/multi-field/zero-arity cells), GAP:burden-spec-decision-log-thinness Major (already cured — burden/mod.rs comment matches storage shape). Checkbox 5 (TPR checkpoint covering 01.1-01.5) intentionally [ ] — fires at section close after §01.5 (FFI exclusion contract) ships per blocks_section_close: ["01.1", "01.2", "01.3", "01.4", "01.5"]. §01.4 status flipped to complete reflecting deliverables shipped; section-close TPR + impl-hygiene + sync-claude gates fire per Step 5 after §01.5.

• 2026-05-13 — /review-plan Step 5 editor pass (Round 5 blind-spots cure). Applied 6 blind-spot findings + 1 architectural risk + 1 cross-cutting concern + 1 design-decision routing per /tmp/review-plan-1jW/blind-spots.json (3-of-3 reviewer convergence on touches: drift; 2-of-3 on register_struct blast radius; codex+gemini+opencode cross-cutting on phase-bleeding, decision-in-implementation, scope-bleed, exit_reason normalization, view-types unspecified). Specific changes: (1) CRITICAL exit_reason normalization — flipped third_party_review.exit_reason from non-canonical user_pause_directive to canonical user_pause_and_resume per /tpr-review SKILL.md §1.7 closed-set enum + /review-plan dispatch routing at scripts/plan_orchestrator/review_plan.py:860 (cures architectural risk that would crash orchestrator on dispatch); (2) CRITICAL §01.5 touches drift — added compiler_repo/compiler/ori_parse/src/grammar/item/extern_def.rs, compiler_repo/compiler/ori_ir/src/ast/items/extern_def.rs, compiler_repo/compiler/ori_diagnostic/src/errors/, plus secondary builtin_types.rs/extern_types.rs/registration/mod.rs/registry/types/mod.rs/registry/types/tests.rs/triviality/ to touches: (cures 3-of-3 reviewer agreement on §01.5 cross-crate work omission); (3) CRITICAL §01.3 register_struct caller blast radius — verified via grep, documented all 17 caller sites (3 user_types.rs primary + 6 builtin_types.rs secondary + 8 registry/types/tests.rs test sites) in §01.3 task body with mandate to update ALL in same commit (cures gemini 2-of-3 finding); (4) CRITICAL §01.3 phase-bleeding cure — replaced ori_arc::ArcClass-based partition (Phase 4 → Phase 2 violation) with ori_types::triviality::Triviality-based partition (uses existing SSOT at triviality/mod.rs:7-8; downward-only consumption respects phase boundaries per compiler.md §Phase-Specific Purity) — cures gemini-only phase-bleeding finding; (5) MAJOR §01.3 field-placement decision authored — decisions/06-burden-field-placement.md decides pub burden: Option<UserBurdenSpec> lives on TypeEntry at mod.rs:40 (sibling to repr at mod.rs:74) NOT on StructDef/VariantDef/TypeKind — cures opencode STRUCTURE:decision-in-implementation finding; §02/§03/§04 now reference concrete TypeEntry.burden slot; (6) MAJOR §01.5 scope-bleed cure — moved RL-31 noalias BEHAVIORAL test pin from §01.5 to §05 (per 00-overview.md:45 ownership); §01.5 keeps only STRUCTURAL FFI burden classification (Burden::owned_fields().is_empty() shape); §05 cross-link verification added to §01.N — cures codex-only scope-bleed finding; (7) MAJOR decision/05 view-types unspecified — added §Concrete view + bridge types — Burden trait surface block with enum TypeRef { Builtin(TypeId), User(Idx) }, OwnedFieldView<'a> { field_path: Cow<'a, [u32]>, field_type: TypeRef }, BorrowedFieldView<'a>, VariantBurdenView<'a>, TransferRuleView<'a>, plus lifetime story + Phase 5 consumption pattern — cures opencode Phase 5 consumer-coherence gap; (8) CROSS-CUTTING test coverage cure — added 3 new success_criteria for parser-level (cargo t -p ori_parse extern_free_annotation), typeck-level (cargo stf extern_free_annotation + cargo stf extern_owned_without_free), and diagnostic-allocation (E2042 in compiler_repo/compiler/ori_diagnostic/src/errors/) test gates beyond the existing Rust-unit gate — cures codex cross-cutting concern; (9) MINOR completion-template gap — added compiler_repo/test-all.sh regression check + cargo c cross-crate compile + phase-boundary regression check + diagnostic-registry update verification + §05 cross-link verification to §01.N completion checklist — cures audit INTEGRITY:completion-template-gap Minor finding; (10) NORMALIZATION — corrected diagnostic surface path from compiler_repo/compiler/ori_diagnostic/src/codes/ (non-existent) to compiler_repo/compiler/ori_diagnostic/src/errors/ (verified path containing E0001-E2041 markdown files + mod.rs:82+ enumeration) per direct verification; allocated E2042 as next available code after E2041. UNRESOLVED ANCHOR PRESERVED: TPR-01-004+008+010 section-not-promoted disposition revisit at Phase 2 entry remains MANDATORY per editorial defense in Round 1 + Round 4 reviewer recurrence — defer-to-Phase-2 is per /tpr-review §7 disposition (2). NO TARGET SCOPE-DOWN: §01 retains 5 ordered subsections + R + N as natural decomposition per routing.md §4 independence test; SIZE_VIOLATION cohesion-edit unchanged from prior editor pass.

Specific changes: (1) COMMENT_HYGIENE_DRIFT — final 2 BUG-01-002 source-comment references stripped from ori_canon/src/lower/collections.rs:18,42 (lower_call + lower_method_call doc comments); workspace-wide grep grep -rn 'BUG-01-002' compiler_repo/compiler/ now returns zero hits. (2) LEAK:swallowed-error at ori_types/src/check/registration/impls.rs:47 — empty-trait-path fallback at register_impl’s trait_name resolution gained debug_assert! guarding parser-invariant breach + concept-only rationale comment per impl-hygiene.md §C-A3; release fallback to "<unknown>" retained so registration continues producing diagnostics. (3) LEAK:swallowed-error at ori_types/src/check/registration/impls.rs:321 — validate_assoc_types’s silent early return on unregistered trait_idx gained debug_assert! citing CK-1 pass 0c registration discipline. (4) LEAK:swallowed-error at ori_types/src/check/registration/impls.rs:371 — check_conflicting_defaults’ filter_map over super-trait providers gained per-element debug_assert! flagging registry inconsistency between find_conflicting_defaults view + get_trait_by_idx resolution; release continues filtering. (5) STRUCTURE:naming-convention-clarity 4-type rename — already cured in earlier session (grep for OwnedFieldOwned|BorrowedFieldOwned|TransferRuleOwned|VariantBurdenOwned returns zero hits across ori_types + ori_arc). (6) GAP:drift-detection-mechanism — already cured: typetag_classification_is_exhaustive_and_consistent test in ori_registry/src/burden/table/tests.rs:258 provides compiler-enforced exhaustiveness via TableClassification::{InTable, DeferredToComposition} partition matching the finding’s recommended shape. (7) GAP:matrix-test-coverage — already cured: 3 matrix cells present at ori_arc/src/lower/burden/tests.rs:197,216,273 (test_burden_ref_empty_owned_fields_parity + test_burden_ref_multi_field_parity + test_burden_ref_zero_arity_variant_burdens_parity). (8) STRUCTURE:registry-md-sync-gap — already cured: .claude/rules/registry.md step 11 (lines 60-66) documents BURDEN_TABLE sync workflow with InTable vs DeferredToComposition decision. (9) PUBLIC_LEAK:wrapper-path-reference at ori_types/src/registry/burden.rs:10-12 + ori_arc/src/lower/burden/mod.rs:3-4 — already cured: both files carry concept-only doc comments with no plans/ private-path references. (10) COMMENT_HYGIENE_DRIFT:inaccurate-comment at ori_arc/src/lower/burden/mod.rs:8 — already cured: module doc now accurately describes Vec collection in VariantBurdenView. Stale-post-migration finding — PLAN_DELIVERY_DRIFT:missing_propagation at bug-tracker/plans/completed/BUG-01-002/00-overview.md cites pre-v5-migration file path; BUG-01-002 has migrated to v5 (plan.json schema) where 00-overview.md no longer exists. Tracker-index SSOT (bug-tracker/closed-bugs.json) shows BUG-01-002 with status: resolved, resolved_date: 2026-04-29 (correct). plan.json internal status: in-progress is a v5-migration data-consistency artifact orthogonal to tracker-index status (bug lifecycle SSOT per state-discipline.md §4); no script API exists to fix without STRUCTURE:llm-direct-json-edit flag. Disposition: deferred-with-anchor — /improve-tooling --gap plan-internal-status-reconciliation would add flip_plan_status_to_complete to scripts/plan_corpus/write.py. Not blocking §01 close because tracker SSOT is correct + no production consumer reads plan.json internal status. Gates: cargo c -p ori_types -p ori_canon --all-targets clean; cargo test -p ori_types --lib check::registration:: 40 passed; cargo test -p ori_registry -p ori_canon -p ori_arc --lib 1385+95+320 passed (zero new failures introduced). §01.H status flipping not-started → complete reflects active-Major findings cured. §01.N /impl-hygiene-review named-skill gate dispatches next per Step 8a; final close awaits its structured-exit-state confirmation.

• 2026-05-17 /commit-push halt skipped — halt_reason: test_all_fail, failing repo: /home/eric/projects/ori_lang/compiler_repo, scope: cross-scope (300-failure baseline pre-existing per §01.1/§01.2/§01.3/§01.4 HISTORY; BUG-04-118 + BUG-04-111 + LLVM crash + AIMS §05+ own the failing tests). §01.H cure-pass work staged in worktree across compiler_repo (3 files: collections.rs doc-comment strip + impls.rs 3 LEAK debug_assert! cures + partial_move.rs parallel-session 1-liner) + wrapper (31 files: §01 close HISTORY + plan-state flips + parallel-session scripts-first-workflow-architecture §02-31 expansions); awaits user-typed /commit-push —bypass per feedback_commit_push_bypass_flag.md OR AIMS §05+ baseline cure to clear. Autopilot routes past dirty-tree block-gate via orchestrator-emitted —bypass-gate dirty_tree per skill-control-contract.md §Autopilot Mode unified hook-failure clause.

• 2026-05-17 — /review-plan Step 5 editor pass (post-§01.H + §01.N close-out blind-spots cures). Applied 3 blind-spot findings + 3 audit cohesion-edits per /tmp/review-plan-bnpfw3R3/blind-spots.json. Specific changes: (1) Codex stale autopilot HISTORY prose: appended **SUPERSEDED 2026-05-17** notes to three 2026-05-13/14 HISTORY entries (§01.1/§01.2/§01.3 commit-push halt blocks) that carried User decision required: framing predating the skill-control-contract.md §Autopilot Mode unified hook-failure clause (autopilot continues past /commit-push halt with dirty tree, no user prompt; parallel-session owner OR future user-typed /commit-push --bypass clears worktree). Supersession preserves audit trail per state-discipline.md §7 while normalizing semantics for current-readers. (2) Gemini §01.5 subsection_depends_on gap: added '01.3' to subsection_depends_on['01.5'] array (line 127) — §01.5’s register_extern_burden helper writes to TypeEntry.burden introduced by §01.3 per decisions/06-burden-field-placement.md §Phase Boundary Cure; DAG edge now reflects schema reality. (3) Gemini signature drift on success_criterion 4: rewrote lookup_burden(ty: ResolvedType, ...) → lookup_burden(ty: TypeRef, type_registry: &TypeRegistry) -> Option<BurdenRef<'_>> matching actual code at compiler_repo/compiler/ori_arc/src/lower/burden_lookup.rs:35 (TypeRef per decisions/05-burdenspec-storage-model.md §Concrete view + bridge types; ResolvedType was an authored-time placeholder predating the bridge-types decision). Audit cohesion-edits accepted as informational: subsection-status-coherence + plan-cleanup-loop-disposition findings record current state correctly per audit-summary §INTEGRITY:subsection-status-coherence + §INTEGRITY:plan-cleanup-loop-disposition (no halt-gating). DEFERRED-WITH-ANCHOR (informational opencode finding): §01.N close-out lacks explicit re-verification gate for truthfulness-cure re-entry pattern AND /review-plan Step 5 editor lacks exit_reason mapping for sections re-opened from complete→in-progress; both are tooling-gap concerns routing to future /improve-tooling --gap review-plan-reentry-classification per tooling-first.md §1 (NOT a §01 deliverable; recorded for orchestrator-side cure). reviewed: false preserved per state-discipline.md §4 — §00.3 close-out runs flip_from_in_review_clean() at plan-level gate, not section-level.
