ARCH — demiurge architecture (narrative SSOT)

Role: this file is the narrative architecture SSOT — how the moving parts fit together, what data flows where, what the contracts are. The complementary files are:

DESIGN.md — gated D-decision audit trail (one decision = one ### Decision N block, numbered SSOT)

PLAN.md — append-only progress log (κ-N phase entries)

AGENTS.tape — enforced rules (@D governance + @F denies)

ARCH.tape — terse machine-readable arch index (tape v1.2)

GOAL.md — one-sentence north-star + honest-position

If a number / list / counter appears here AND in another file, the other file is the SSOT (g_ssot_single_source, D50). This file describes the shape of the system, not the running counts.

Last reconcile: 2026-05-20 · D77 (chem + bio domains) · D78 (graph DAG + multi-facet tag).

0. First principle — hexa-only (ultimate form)

Every producer, kernel, record schema, and verify oracle's ultimate destination is hexa-native (~/core/hexa-lang/). Python adapters, Swift cockpit, external CLI are transitional pointers (bridges) — not endpoints. Sibling repos (hexa- rtsc/ · hexa-matter/ · hexa-bio/ · hexa-chem/) carry domain narrative only (markdown · physics derivation · spec · citation index) — no code per D116 amendment of D14/D17/D77. A cell can only be flipped to absorbed=true non-provisionally when its hexa-native parity port exists AND matches the transitional implementation to a cited tolerance. Otherwise: GATE_OPEN / provisional=true, regardless of how many intermediate checks pass.

Authority: AGENTS.tape @D g_hexa_only (INDEX top, body block, 2026-05-20) · DESIGN.md D80 · raises g_hexa_native (D14+D18) from absorption-time preference to absolute endpoint rule.

Orthogonal to the hexa-native endpoint axis is the execution venue axis — where the FLOPs actually run. Heavy / install-gated / cross-platform-audit / GPU compute may route through pool (a first-class infrastructure layer · ~/core/pool/ CLI · canonical precedent at ~/core/hexa-lang/stdlib/material/cross_code_dft.py:: _pool_cli_present). Pool is a venue, not a verb (POOL.md §3.5) — the 7-verb spine and the hexa-native endpoint rule are unchanged by pool dispatch. Records that route through pool surface provenance.pool_host + provenance.pool_command; R4 absorbed=false 영구 carries over (POOL.md §3.2). Cross-link: POOL.md (this repo · ~517 line · 7 § spec).

Examples:

endpoint-compliant: chip §B sweep_oracle_parity.hexa (κ-43 / D70) — first dynamic absorbed=true, BECAUSE the hexa-native oracle exists.

provisional: cern+synth (κ-51) — Xsuite ⇄ Wiedemann/Lee match on a Python substrate. honest flip at the algorithm layer, but hexa-native FODO twiss kernel does not yet exist → provisional=true, subject to demotion if the hexa-native port diverges.

1. One-line shape

demiurge is a graph of domains with prerequisite edges between them, where each domain has 7 verb cells that dispatch to substrates living in hexa-lang (or sibling hexa-* repos), and the cockpit reads the resulting typed records under a single honesty gate (g3).

2. Domains — graph, not partition (D78)

2.1 Nodes

18 domains live under domains/<name>.md. Each one is a node in the domain graph. Domain ≠ project; the project is a pointer (D-pending, see §5).

Molecular tier (substrate-heavy):  matter · chem · bio
Device tier:                       chip · firmware · sscb · rtsc ·
                                   brain · aura
Component tier:                    component · bot
System tier:                       energy · grid · mobility · scope ·
                                   space · cern · antimatter · fusion

Tier = facet tag, not a partition. A domain can carry multiple tags (D78 picked option 3). See §2.3.

2.2 Prerequisite edges (DAG)

Each domains/<name>.md carries a header field:

prerequisites: [<other domain ids>]

The collection of edges forms a directed acyclic graph (DAG) — when a project picks a start domain, the system traverses its transitive closure and proposes the upstream domains to include.

Example chains (illustrative, exact edges live in each domains/*.md):

- bio (drug discovery)  →  chem (synthesis)  →  matter (formulation)
- chem (catalyst)       →  matter (carrier)
- fusion                →  rtsc (HTS coil)   →  matter (cryostat alloy)
- chip                  →  firmware                — software on top
- scope                 →  component (optics frame) → matter

Two domains can share an upstream prerequisite (e.g., both bio and chem may depend on matter); this is why a DAG (not a tree) is the correct shape.

2.3 Facet tags

Each domain header also carries:

facets:
  scale:    Molecular | Device | Component | System
  cluster:  matter | bio | chem | physical | engineering | system | ...
  hostility: macos-clean | macos-partial | macos-blocked | linux-pool

Facets are multi-tag, not mutually-exclusive partitions — bio might carry cluster: [bio, chem] if its prerequisite chain crosses both clusters. The cockpit New Project UI uses facets only as a filter for the initial domain pick.

2.4 Why graph, not strict partition

User observation (2026-05-20): real systems cross-cut domains. A drug project touches bio (target) + chem (molecule) + matter (formulation) + component (delivery device). Forcing each domain into a single tier creates false either/or choices and hides the real prerequisite relationships. D78 picked option 3 = graph DAG + multi-facet tag.

2.5 Example — `domains/ufo.md` (HEXA-Disc, 7-stage propulsion)

The canonical worked example for "graph, not partition" + "multi-level DAG" — a top-of-stack domain whose direct prerequisites are three sister sibling repos (hexa-fusion, hexa-antimatter, hexa-rtsc), each of which transitively depends on rtsc as a foundation technology. The sibling-repo ~/core/hexa-ufo/ README §Status anchors the mapping (Stage-1 Meissner → rtsc · Stage-2 cruise → fusion · Stage-3 orbital → antimatter).

# domains/ufo.md — header (D78 schema, Option 3: direct prereq only)
prerequisites:
  - fusion       # Stage-2 MHD + tabletop fusion cruise
  - antimatter   # Stage-3 antiproton γ-rocket orbital
  - rtsc         # Stage-1 Meissner diamagnetism (direct)

facets:
  scale:    System
  cluster:  [physical, propulsion]           # multi-tag, not partition
  hostility: macos-clean                     # all 3 substrates macOS-clean

substrate_ssot: ~/core/hexa-ufo/             # D17 sibling-repo precedent
                                             #   v1.0.0, DOI 10.5281/zenodo.20102628

DAG fragment (3-level: foundation → application → integration):

                 ┌─────┐
                 │ ufo │              ← LEVEL 3 (integration apex)
                 └──┬──┘
            ┌───────┼───────┐
            │       │       │
       ┌────▼───┐ ┌─▼─────┐ │
       │ fusion │ │antimat│ │         ← LEVEL 2 (application)
       └────┬───┘ └──┬────┘ │
            │        │      │
            └────────┼──────┘
                     │
                ┌────▼────┐
                │  rtsc   │           ← LEVEL 1 (foundation)
                └─────────┘

direct prereq edges (Option 3 schema):
  ufo → {fusion, antimatter, rtsc}
  fusion → {rtsc, ...}          (per domains/fusion.md cross-refs)
  antimatter → {matter, rtsc}   (Penning trap SC magnet + trap matter)

transitive closure (computed by graph traversal, NOT stored):
  ufo* = {fusion, antimatter, rtsc, matter, ...}

Why this is the chosen example:

Multi-level DAG is visibly necessary — rtsc shows up once as ufo's direct prereq (Stage-1 Meissner) and transitively through fusion and antimatter. Storing only direct edges (Option 3) keeps the SSOT minimal; the cockpit traversal proposes the closure.
rtsc-as-foundation is real — domains/grid.md cross-references rtsc for HTS power cable, fusion uses tokamak SC coils, antimatter uses Penning trap SC magnets, cern uses LHC SC dipoles. Stripping rtsc breaks ≥4 downstream domains.
Sibling-repo pattern (~/core/hexa-ufo/) makes the D17 / D77 boundary concrete — substrate too large for one stdlib subtree, so it lives outside. The demiurge-side domains/ufo.md is a pointer.
Speculative tail honestly tracked — ~/core/hexa-ufo/ Stages 4–7 (warp / wormhole / dim-jump / dim-use) carry 13 OPEN falsifiers (F-WARP-1..3 / F-WORM-1..3 / F-DIM-1..3 / F-USE-1..4). All UNPROVEN at v1.0.0. The demiurge cell layer respects this: any ufo+verify record carries scope_caveats spelling out that bookkeeping-closure ≠ empirical truth (g3).

Project example over the same graph — a "ufo close-encounter trace" project (cockpit "New Project" flow):

step 1.  Facet filter: cluster=propulsion          → narrows to ufo + chain
step 2.  Pick start domain = ufo
step 3.  Auto-propose transitive closure:
            [rtsc, matter, fusion, antimatter, ufo]
                 ^foundation              ^integration apex
step 4.  Project.walk = topological sort of the closure
         Project.startDomain = ufo
         Project.verbState = per-domain 7-verb state

The same domains/ufo.md node serves any number of projects (D78 — "domain ≠ project, project is pointer over the graph"). A drug-discovery project would start at bio and traverse {chem, matter} — a completely different transitive closure over the same graph.

3. The 7-verb spine (D5)

Every domain carries the same seven verbs, each of which dispatches a cell:

명세 (specify)  → architecture spec, IETF/AUTOSAR-class doc, cited
구조 (structure)→ topology / task tree / inventory
설계 (design)   → real source artifact (RTL, KiCad, C, URDF, .step)
해석⟲ (analyze) → simulation, what-if, error analysis
합성 (synthesize)→ build the deliverable
검증 (verify)   → independent measurement against an oracle
인계 (handoff)  → packaged release + SBOM + cited audit trail

A (verb, domain) pair = a cell. With 18 domains × 7 verbs = 126 cells. Of those, ROI 1→18 (currently 17) have a real engine tool dispatched; the rest fall back to the LLM "honest-gap" path.

4. Substrate & kernel layer (D17 / D61 / D72)

4.1 Where the math lives

demiurge/ carries no compute code. Every producer script is owned by hexa-lang/stdlib/ (D17 / D61). The Swift Producer.swift in demiurge spawns python3 ~/core/hexa-lang/stdlib/<domain>/<script>.py <output_dir> and decodes the resulting JSON into a typed Record.

4.2 D72 — two-layer kernel

hexa-lang/stdlib/
├── kernels/              ①a domain-agnostic math (13 today)
│   ├── graph/  fem/  mc_transport/  orbital/  wave_optics/
│   ├── noc_sim/  logic_synth/  circuit/  plasma/  neural/
│   ├── signal_proc/  urdf/  solar/
│   └── (cfd, ode_pde, ...)  planned
│
└── <domain>/             ①b thin domain adapter
    ├── component/gmsh_skfem.py    → calls kernels/fem/
    ├── grid/networkx_basics.py    → calls kernels/graph/
    ├── cern/xsuite_optics.py      → adapter-only (single domain)
    └── ... (15 today, +chem, +bio post-D77 = 17)

A kernel may have many adapters. Example payoff: kernels/mc_transport/ is consumed by 4 domain adapters (antimatter+analyze, fusion+verify, energy+verify, antimatter+verify) — the N+M reuse the D72 layer was designed for.

4.3 D74 — ProducerRegistry (cells with alternatives)

Most cells have one substrate; a few carry alternatives. Example: (cern, analyze) has both pylhe (legacy LHE round-trip) and xsuite-tracking (real physics, default). ActionDispatch consults ProducerRegistry.entries first; missing keys fall through to the hardcoded switch (additive, not invasive).

ActionDispatch.runEngineTool(verb, domain, producer:)
    │
    ├─ ProducerRegistry.entries[(verb, domain)]?
    │   ├─ entry.pick(producer ?? default) → variant.run()
    │   └─ unknown producer → honest no-record
    │
    └─ switch (verb, domain) → hardcoded Producer.run() (default)

CLI: action analyze cern --producer pylhe.

4.4 Sibling repos (D17 / D77 / D116 amendment 2026-05-21)

D116 amendment: sibling repos = 문서만 (docs only) · 모든 substrate code = ~/core/hexa-lang/stdlib/<domain>/ ONLY. D14/ D17/D77 의 "sibling repo for large substrate sub-trees" precedent 는 본 D116 으로 role-only-narrative 로 amendment.

hexa-lang is the single SSOT for ALL stdlib code (substrate algorithms · kernels · math · physics models · validation logic). Sibling repos serve as doc-only domain SSOTs — domain narrative (*.md) · physics derivation notes · citation indexes · spec · clean-room provenance. No code (no .hexa · no .py · no .swift in sibling repos):

~/core/hexa-rtsc/     — RTSC.md 도메인 narrative · 5-gate definition
                        · candidate matrix · physics derivation
                        notes (R4 cross-link 의 doctrinal source).
                        **docs only · NO code (D116)**.
~/core/hexa-matter/   — material domain narrative + taxonomy +
                        citation index (D17 precedent · D116 으로
                        code allowance 제거). **docs only**.
~/core/hexa-bio/      — molecular biology domain narrative + spec
                        (D77 planned · D116 으로 docs-only 정착).
~/core/hexa-chem/     — chemistry domain narrative + citation index
                        (D77 planned · D116 으로 docs-only 정착).

The demiurge-side domains/<id>.md is the active engineering pointer (carries deliverable spec + 7-verb cell wiring + cited sources); sibling repos carry the expanded narrative (physics derivation · longer-form spec · multi-paper citation cluster) when the spec exceeds what a single domains/<id>.md page can hold. Cellrun.hexa (D111 + ARCH §4.5) reads .demi manifest from demiurge domains/ · resolves substrate script path under ~/core/hexa-lang/stdlib/<domain>/ (NEVER a sibling repo).

Migration scope (Phase B/C of D116 · multi-cycle): sibling repos that currently hold algorithm code (hexa-rtsc/verify/calc_ bcs.hexa · calc_mcmillan.hexa · calc_hc2_48t.hexa · falsifier_ check.hexa · 등 추정 4개) 점진 ~/core/hexa-lang/stdlib/<domain>/ 이전. Sibling repo 의 narrative-only role 정착까지 multi-session.

4.5 D111 — Generic verb-cell dispatch (`cellrun.hexa` + `.demi` manifest)

D111 (2026-05-21) ratifies the architectural shift away from hardcoded per-cell *Producer.swift classes toward a hexa-native generic dispatcher. This subsection describes the target shape; §4.3's ProducerRegistry + ActionDispatch switch is the transitional bridge (D14 / D18 / §0 hexa-only ultimate form).

Pain that triggered D111 (2026-05-21 sscb 7-verb walkthrough · 실 측정 ground truth):

46 cockpit/Sources/DemiurgeCore/Loaders/*Producer.swift classes (50-150 line each · spawn substrate + parse stdout + emit typed record · (domain × verb) axes scatter pattern)
40+ hardcoded (.verb, "domain") switch cases in ActionDispatch.swift · each new cell wiring = +1 Swift class
- +1 switch case
Adding a new domain requires writing 4-7 Swift producer classes (200-400 line each) + matching dispatch cases — Swift code per domain is essentially prose (ai-native 위반)
ARCH §0 first principle says producer's ultimate destination is hexa-native — Swift producer classes are §0 endpoint targets too

Target shape:

ActionDispatch.dispatch(verb, domain)                                    [Swift · thin]
    │ spawn
    └─ hexa run stdlib/cockpit/cellrun.hexa <domain> <verb>               [hexa-native]

Cost reduction (new domain or new cell):

Migration path (Phase A..E · 15-20 session est · honest correction 2026-05-21 저녁 per Phase B step 3 observed cost — was 10-17 session at D111 ratification morning):

Phase A: stdlib/cockpit/cellrun.hexa Phase A scaffold (hexa- lang isolated worktree hexa-lang-cellrun · concurrent agent 2026-05-21 작업 중) — manifest loader + g3 gate + selftest. PR open 안 함 (review 대기).
Phase B: domains/sscb.demi proof-of-concept (7 verb · 3 wired + 4 honest-skip) · existing record byte-equal regression verify. 1-2 session.
Phase C: 46 producer 점진 migration (1 도메인 / commit · .demi add + Swift producer + switch case 제거 + regression test PASS). 8-13 session (Phase B step 3 실측 20 min/cell · 원본 12 min/cell 의 3× · 46 producer × 20 min ≈ 15-20 시간 total focused work · 도메인 별 1 session ≈ 3-6 cell).
Phase D: ActionDispatch.swift 가 switch 0 case · 5-line thin spawner 로 축소. 1 session.
Phase E (optional): Swift-side record schema 도 manifest- declared fields 로 generalize (per-domain CodingKey 폐기 검토). 2-3 session.

Phase B observed cost (2026-05-21 저녁 · honest correction source): 3 sscb cells (6.5% of 46) ≈ 1 hour focused work → 20 min/cell observed (3× original 12 min/cell estimate). Overhead sources: format-mismatch fixup · Verb Korean→English mapping · Python version debug · payload-flattening decisions. Phase A bug fixes in flight (cellrun.hexa _split_csv quoted-comma · Verb. canonical Korean drift · python candidate list · concurrent agent · PR update on d111-phaseb-sscb-migration) will reduce future per-cell cost — but 20 min figure already absorbs some recovery overhead, so envelope stays honest at 15-20 session.

Axis distinction:

D111 = dispatch-mechanism axis (plumbing) · cell 의 absorbed 자체와 무관 (D103 dimension separation 유지)
D80 endpoint rule 의 cockpit-dispatch axis 적용 — kernel/ producer-content/record-schema axes 와 별 axis
D74 ProducerRegistry alternatives 패턴은 [cell.<verb>.<variant>] manifest 섹션으로 자연 흡수 (Swift ProducerRegistry class 도 cellrun.hexa 안 selection logic 으로 흡수)

Cross-link: DESIGN.md D111 (full rationale + rejected alternatives + Phase A..E) · D112 (Verb canonical → English wire form · bug #2 fix) · D113 (payload flattening · sibling .meta.json roll-up) · D114 (stdlib SSOT enforcement · code-shape × repo boundary) · D116 (sibling repos = docs only · amendment of D14/D17/D77) · D14 / D18 / D74 / D80 / D83 (.demi precedent) · CLAUDE.md Principles 1 + 2 + 4 + 5 (ai-native · hexa-first · domain-meta-domain · lattice-as-tool) · ARCH §0 first principle · §4.4 (sibling repos docs-only role per D116).

5. Projects — pointers over the graph

struct Project {
    let id: ProjectID
    let name: String
    let createdAt: Date

    // Pointer-only — does NOT own domain content.
    let startDomain: DomainID
    let walk: [DomainID]   // ordered chain (incl. prerequisites)

    // Mutable run state lives on the project; producers' typed
    // Records live under exports/<domain>/<cell>/<stamp>/.
    var verbState: [Verb: VerbState]
    var manifestPath: URL   // D45 — App Support persisted JSON
}

The project never modifies domains/*.md. The cockpit "New Project" wizard:

step 1.  Facet filter (cluster + scale)         — narrows the 18 nodes
step 2.  Pick start domain (e.g., bio)          — graph traversal
step 3.  Confirm prerequisite chain             — DAG transitive closure
step 4.  Project name + manifest persistence    — App Support (D45)

A project may add or remove a domain from its walk later; the underlying domains/*.md graph is unaffected. Multiple projects can share the same domain (a single SSOT).

6. SceneDescriptor (D76)

3D viewers in the cockpit are not hardcoded per domain. Instead:

domains/*.md → toScene() → SceneDescriptor (Codable Swift)
                              │
                              │  primitive enum:
                              │   box · annulus · helixTube · sphere ·
                              │   mesh · arrow · label
                              │
                              ▼
            GenericSceneView3D (RealityKit ARView)
              ├─ orbit drag / scroll zoom
              └─ MeshDescriptor helpers (annulus / helix tube / ...)

ComponentGeometry.toScene() and RtscGeometry.toScene() are the first two emitters; the goal is for every domain that has a geometry to emit a SceneDescriptor instead of a custom view. The domain-specific Views (ComponentView3D, RtscView3D) are deprecated once their toScene() is wired and visually verified.

7. Records, gates, honesty (D9 / D12 / g3)

Every Producer emits a typed Record (Swift Codable) carrying:

struct Provenance {
    let absorbed: Bool                     // false until measured parity
    let producer: String                   // "lib@ver" — NOT the part
    let measurementGate: MeasurementGate   // OPEN / B_PINNED_MET /
                                           // CLOSED_MEASURED / FAILED
    let scopeCaveats: [String]             // honest what-this-isn't
}

absorbed=true flips ONLY on a measured gate — typically a cited analytic oracle or an external benchmark hit within a stated tolerance. Two dynamic flips so far: chip §B+§D (κ-43, D70) and cern+synth (κ-51, vs Wiedemann/Lee). Everything else is GATE_OPEN, absorbed=false. The scope_caveats field is non-optional — every record carries an explicit list of what the measurement does NOT cover.

The g3 contract: never silent-pass, never over-claim, never set a gate without a citation. Install-gated and platform-gated skips are honest: the substrate emits a record with skipped_reason set and absorbed=false rather than crashing or falsifying success.

The cockpit reads domains/*.md, exports/<domain>/* and the manifest JSON; it never writes to domains/*.md. AR / visionOS is the stated portability target (n_cockpit_ar_target) — that's why RealityKit (not SceneKit) is the 3D layer.

9. Governance summary (AGENTS.tape)

`@D` rule	one-liner
`g_demiurge_pointer_only`	demiurge = pointer / spawn wrapper only (D61)
`g_stdlib_ownership`	`stdlib/` ⊂ hexa-lang only (D15)
`g3_no_over_claim`	never assert unmeasured (D12)
`g_clean_room`	public-surface only, no closed-binary RE (D1)
`g_decouple`	hexa-bio + comb + hexa-matter typed-interface consumed (D2+D11)
`g_scope`	full scope incl. execution/absorption, no big-bang (D10+D12)
`g_absorption`	per absorbed tool: one rfc_0NN, clean-room, measured gate
`g_hexa_native`	absorb into hexa intrinsics, never shell out (D14+D18)
`g_swift_native`	SwiftUI / Foundation / AppKit / RealityKit first (D26)
`g_cockpit_isolation`	cockpit reads exports/docs one-way (D27+D41)
`g_ssot_single_source`	one fact, one canonical home (D50)

Forbidden (@F): creating a stdlib/ tree under demiurge, over-claim, closed-binary RE, silent skip, premature tombstone.

11. Worked simulations (design test, not implementation)

Two end-to-end project simulations were run on paper to design-test the §2 graph + §5 project-pointer + §7 honesty model before the .demi parser + DomainGraph code landed. Each simulation walks a hypothetical user from New Project through every cell of the transitive closure, recording where the design holds and where the gaps appear. These are not measured records — they are design walk-throughs, kept as canon test cases.

11.1 Simulation A — `alien-disc-mk1` (ufo from scratch)

User opens cockpit → New Project wizard. cluster=propulsion filter narrows the 19 nodes; user picks ufo as the start domain; DAG transitive closure proposes {ufo, fusion, antimatter, rtsc, matter} (matter via antimatter prereq edge); user names "alien-disc-mk1".

Simulation A — gaps discovered (G1–G5)

✅ 잘 작동
  - DAG closure traversal: 5 도메인 자동 chain (Day 1→5 토폴로지 정렬)
  - g3 honesty: 35 cells 중 1개만 진짜 absorbed=true (matter), 정직
  - sibling repo pointer: ufo → hexa-ufo dispatch 자연 매핑
  - 13 falsifier preregister: 미증명 explicit OPEN (g3 위반 0)

⚠️ 갭 (현재 demiurge 가 부족)
  G1. cockpit 새 프로젝트 wizard 가 아직 facet → DAG 인지 X
      (현 NewProjectSheet 는 평면 list, D78 implementation 필요)
  G2. cell-skipped 일관 보고 UI 없음 (record JSON 안 매몰)
      → "왜 skipped 인지" project-level dashboard 필요
  G3. domains/matter/* pointer 가 D17 산출 (absorbed=true)을 어떻게
      cell record 로 surface 하는지 ActionDispatch 매끄럽지 않음
  G4. ufo 의 sister-repo dispatch — 현재 `hexa-ufo selftest` spawn 패턴 없음
      (sscb/cern/scope 처럼 stdlib/<domain>/*.py 가 아니라 외부
       sibling repo CLI binary 호출 → ProducerRegistry 확장 필요)
  G5. 13 falsifier preregister CSV 가 cell record schema 와 별개
      → ufo+verify Record 가 falsifier 표를 typed field 로 담아야

🛠️ design 통찰 (D78 graph + .demi format 이 풀어주는 갭)
  - G1 → DomainGraph.transitiveClosure(id) + cockpit wizard 갱신
  - G2 → exports/*/skipped.summary.json + ProvenanceBanner 확장
  - G3 → MatterAnalyzer 의 pointer-pattern 을 generic 패턴화
         (sibling-repo dispatch 표준화)
  - G4 → ProducerRegistry 의 variant.run 이 sibling-repo binary 도 spawn

  - G5 → FalsifierEntry struct (Codable, monotone OPEN/CONFIRMED/DEMOTED)
         + UfoVerifyRecord 에 [FalsifierEntry] 필드

11.2 Simulation B — `aura-clip-mk1` (hexa-aura from scratch)

User opens cockpit → New Project wizard. facet filter (cluster=sensing

✅ ufo 시뮬레이션 갭 (G1-G5) 모두 재발견 — pattern 일관

🆕 aura 시뮬레이션이 새로 발견:
  G6. Cascade falsifier — hexa-aura README 의 conditional rule
      "if hexa-rtsc falls → F-AURA-2 DEMOTED" 가 명시.
      이건 cross-domain *falsifier dependency* — DAG edge 의 일종.
      현재 DomainGraph 에 falsifier-cascade 표현 없음.
      → FalsifierEntry 에 `demoted_if: <other-falsifier-id>` 필드 추가
         또는 DomainGraph 가 falsifier 도 node 화 (super-graph)

  G7. Proprietary-mandatory gate — Sim4Life FDA MDDT 같은
      open 대체 없는 도구가 cell verify path 의 정직 차단.
      현재 substrate gate ("install 안 됨") 와 commercial gate
      ("FDA 의무, OSS 없음") 가 구분 안 됨.
      → record schema 에 gate_type: install | platform | regulatory |
         proprietary-irreplaceable 필드

  G8. n=6 lattice invariant cross-check —
      σ·φ = n·τ = J₂ = 24 가 모든 HEXA-family 의 invariant.
      aura/cern/ufo/rtsc/bio/chip 6 sibling 이 모두 이 invariant 공유.
      → DemiurgeCore 에 LatticeInvariant 모듈 (assertion engine)
         project-wide audit 가능

🛠️ 통찰
  - ufo + aura 둘 다 *integration apex* 패턴 (DAG top, sibling sub repos)
  - n=6 lattice 가 cross-project 공통 invariant — 별도 audit 의미 있음
  - falsifier cascade (cross-domain) 가 진짜 cross-domain bookkeeping
    의 핵심 — demiurge 의 정직성 표면의 핵심 case

cross-domain rule   13 OPEN preregister        cascade DEMOTE (rtsc → F-AURA-2)

핵심 발견: rtsc 가 두 프로젝트의 foundation 공통 — D72 N+M payoff 의 도메인-수준 사례. 같은 rtsc 인스턴스가 alien-disc-mk1 / aura-clip-mk1 둘 다 prereq. 도메인 = 다중 프로젝트 공유 노드 (사용자 명시: "완성된 도메인은 여기저기 쓰일 수 있으니까").

Integrated gap list (G1–G8)

🎯 새 갭 통합 list (G1-G8)

G1. cockpit NewProjectSheet — facet → DAG 인지 (D78 impl 핵심)
G2. cell-skipped 일관 보고 UI
G3. sibling-repo pointer pattern 표준화 (matter / ufo / aura)
G4. ProducerRegistry 가 sibling-repo binary spawn
G5. FalsifierEntry 가 record schema typed field
G6. Cascade falsifier (cross-domain DEMOTE rule)
G7. gate_type 구분 (install / platform / regulatory / proprietary)
G8. n=6 lattice invariant cross-check 엔진

우선순위 추천:

첫 라운드: G1 + G3 + G5 (D78 graph + sibling pattern + falsifier typed) — 가장 fundamental
둘째 라운드: G2 + G7 (UI / gate_type 정직성 표면)
셋째 라운드: G4 + G6 + G8 (cascade + lattice audit)

비교 — 기존 EDA = project-bound (각 프로젝트가 자기 도메인 데이터 자체 보유). demiurge = domain-shared (도메인 1개 + 프로젝트 N 개 포인터). 시뮬레이션 두 개가 rtsc 공유로 직접 입증. monolithic CAD 가 못 하는 cross-domain bookkeeping 정직성 표면.

라운드 1 — fundamental (D78 + sibling + falsifier schema)

G1. cockpit NewProjectSheet — facet → DAG 인지
- κ-56: Domain.swift 에 prerequisites + facets fields 추가. DomainGraph.swift 신규 (transitiveClosure / topologicalSort / byScale / byCluster / roots / leaves). DomainCatalog 19 entries 에 prereq + facet 박음.
- κ-57: D83 .demi format + domains/INDEX.demi (19 [<id>] records) + DemiParser.swift + DomainLoader.swift 신규. DomainCatalog.all 가 runtime-load (loadAllOrFallback). 도메인 추가는 이제 .demi 한 section (Swift 변경 0).
- κ-58: D84 2-tier (built-in + user u/ prefix). DomainLoader. loadUserDomains() + Project.walk 필드. user 도메인이 built-in prereq 로 사용 가능 (DAG 자연 확장).
- κ-59: NewProjectSheet step 3 (confirm) 에 DAG closure preview chip stack 추가. closureWalk computed property 가 DomainGraph.transitiveClosure + topologicalSort 호출. start 도메인은 accent 색, prereq chain 은 secondary chip 으로 표시. u/<id> 도메인은 "내 도메인" badge. Project.walk 가 closure 로 자동 채워져서 onCreate 호출. build CockpitApp OK (2.94s).
- deps: D78 graph + .demi parser + DomainGraph.transitiveClosure

  - cockpit/Sources/DemiurgeCore/Loaders/DomainLoader.swift (new, ~80 LOC)
  - cockpit/Sources/DemiurgeCore/Models/DomainGraph.swift (new, ~120 LOC)
  - domains/INDEX.demi (new SSOT — 19 [<id>] records)

- exit:
  - swift build green
  - DemiurgeCLI action list-domains --facet cluster=propulsion 작동
  - cockpit 새 wizard 3-step 매뉴얼 검증
G3. sibling-repo pointer pattern 표준화 (matter / ufo / aura)
- κ-56: SiblingRepoSpawner.swift 신규 (D17 entrypoint resolver + uniform spawn — ~/core/hexa-<id>/cli/hexa-<id> 또는 fallback verify/run_all.hexa 등 canonical 후보 4개 자동 시도).
- κ-60 decision (no-refactor): MatterAnalyzer.swift 는 D17 historical precedent 로 그대로 보존. commit-hash pin / per- script PASS parsing / closure-invariant gate 결정 등 hexa-matter 특화 처리가 generic helper 로 흡수하면 손실. 미래 sibling-cell (ufo / aura / cern / antimatter / fusion / rtsc / space / brain / bio / chem) Producer 가 SiblingRepoSpawner 사용하는 게 G3 목표 충족 (regression 위험 0).
- deps: G1 (DomainLoader 의 substrate_ssot 필드 읽기)
- new file:
  - cockpit/Sources/DemiurgeCore/Loaders/SiblingRepoSpawner.swift (new helper — spawn <repo>/cli/<binary> or <repo>/<entry>.hexa)
- refactor:
  - MatterAnalyzer.swift D17 spawn 패턴을 SiblingRepoSpawner 호출로
  - 신규 UfoAnalyzer.swift / AuraSensorAnalyzer.swift 가 같은 helper 재사용 (코드 중복 0)
- exit:
  - matter+analyze 가 기존과 byte-identical record (회귀 0)
  - 새 도메인이 sibling-repo 포인터 등록할 때 코드 1줄 (SiblingRepoSpawner.spawn(.aura))
G5. FalsifierEntry 가 record schema typed field
- κ-56: FalsifierEntry.swift 신규 (typed monotone OPEN / CONFIRMED / DEMOTED + demotedIf for G6 cascade).
- κ-60: UfoVerifyRecord.swift + AuraVerifyRecord.swift 신규 (typed Codable). 각각 falsifiers: [FalsifierEntry]? 필드 + hexaNativeParity: HexaNativeParityRef? (D80) + AuraVerifyRecord 는 latticeInvariant: LatticeInvariantResult? (G8 stub) 추가. ufo (13 falsifiers F-WARP/WORM/DIM/USE) + aura (F-AURA-{1..4} 15 sub-IDs, G6 cascade demotedIf 활용 준비).
- deps: 없음 (Codable schema 확장만)

  - ufo+verify Record JSON 안 falsifier 표가 typed array
  - cockpit ProvenanceBanner 가 falsifier OPEN/CONFIRMED/DEMOTED count 표시

라운드 2 — 정직성 표면

G2. cell-skipped 일관 보고 UI
- κ-61: SkippedCellsAggregator.swift 신규 (Foundation only, exports/ 디렉토리 scan + 모든 JSON 의 skipped_reason field 수집 + GateType 자동 추정 fallback heuristic). SkippedCellsDashboard.swift 신규 (SwiftUI) — gate-type chip summary + filter + 셀 list + "내가 풀 수 있는 갭" count (userResolvable). 모든 17+ dispatched cell 이 통일 dashboard 안에 visible.
- deps: G1 부분 (DomainGraph 가 cell coverage 알아야)
- runtime artifact:
  - 각 project 의 exports/<domain>/skipped.summary.json — verb × cell × skipped_reason 매트릭스
- edit:
  - cockpit/Sources/CockpitApp/Views/ProvenanceBanner.swift 확장 → "이 cell 이 왜 skipped 인지" 한 줄 표시
  - 새 view SkippedCellsDashboard.swift (project pane 안 별도 탭)
- exit:
  - alien-disc-mk1 / aura-clip-mk1 모두 dashboard 에 skipped 이유 clean 표시 (29/27 cell 중 X 가 install-gated, Y 가 platform-blocked)
G7. gate_type 구분 (install / platform / regulatory / proprietary)
- κ-61: GateType.swift 신규 — installGated / platformGated / dataGated / regulatoryGated / proprietaryOnly / hexaNativeAbsent (D80 surface) / producerAbsent / unspecified 8 case. userResolvable predicate (user 설치/다운로드 로 풀 수 있는 갭) + hexaNativeBlocked predicate (G6/D80 cascade). 각 case 가 Korean label 보유 (cockpit ProvenanceBanner + G2 dashboard 사용). substrate 측 typed emit 점진 적용 — 그 동안 G2 aggregator 가 skipped_reason text 에서 heuristic fallback.
- deps: G5 (Record schema 변경 같이 가는 게 효율)
- edit:
  - F1F2Record.swift 의 MeasurementGate enum 에 gate_type 소속 field 추가 OR scope_caveats 안 typed key
```
enum GateType: String, Codable {
    case installGated         // brew install missing
    case platformGated        // macOS Wine / Linux only
    case regulatoryGated      // FDA Class III, PMA, MDDT
    case proprietaryOnly      // Sim4Life / ANSYS / FLUKA
    case dataGated            // OPENMC_CROSS_SECTIONS
}
```
  - 모든 17 substrate Python script 가 gate_type field 출력 (점진, cell 단위 PR)
- exit:
  - Project dashboard 가 gate_type 별 cluster 표시 (예: "23/42 install-gated, 5/42 regulatory-gated proprietary-only")

라운드 3 — cross-domain audit

G4. ProducerRegistry 가 sibling-repo binary spawn
- κ-62: ProducerRegistry+Sibling.swift 신규 — extension on ProducerRegistry with siblingRepoVariant(id:domainID:verb: displayName:) factory. variant.run closure 가 SiblingRepoSpawner. spawn 호출 + exports/<domain>/<verb>/<stamp>/ 디렉토리 자동 생성 + emitted JSON 으로부터 recordID 추출. cern+analyze 의 pylhe / xsuite-tracking 패턴이 일반화됨 — 새 (verb, domain) cell 이 sibling-repo binary 인계 받을 때 entries dict 한 줄 추가 ("hexa-ufo": ProducerRegistry.siblingRepoVariant(...)).
- deps: G3 (SiblingRepoSpawner 헬퍼 먼저)
- edit:
  - ProducerRegistry.swift 확장 — variant.run closure 안에서 SiblingRepoSpawner.spawn(.hexa_ufo, command: "selftest") 호출
  - cern+analyze pylhe / xsuite-tracking 패턴 (D74) 을 sibling-repo variant 로 확장: (ufo, synthesize) → hexa-ufo CLI variant
- exit:
  - 새 도메인이 sibling-repo CLI 인계 받을 때 entries dict 1 줄
G6. Cascade falsifier (cross-domain DEMOTE rule)
- κ-62: FalsifierCascade.swift 신규 — BFS over demotedIf edges. apply(_ entries:) 가 monotone fixpoint (OPEN entry 가 upstream DEMOTED 면 본인도 DEMOTED, CONFIRMED/DEMOTED 는 freeze). FalsifierCascadeResult = updated entries + diagnostic [FalsifierCascadeHop] (target / cause / reason) — cockpit dashboard 에서 "demoted because of …" 표시 가능. hexa-aura README 의 "if hexa-rtsc falls → F-AURA-2 DEMOTED" 정확 매핑.
- deps: G5 (FalsifierEntry.demotedIf) + G1 (DomainGraph)
- edit:
  - DomainGraph.swift 에 falsifierCascade(start: FalsifierID) -> [FalsifierID] 추가
  - hexa-rtsc 의 root falsifier 가 DEMOTED 되면 aura/F-AURA-2 도 auto-DEMOTED 표시 (project-wide audit)
- exit:
  - DemiurgeCLI falsifier-audit aura-clip-mk1 가 cross-domain cascade 매트릭스 출력
G8. n=6 lattice invariant cross-check 엔진
- κ-62: LatticeInvariant.swift 신규 — canonicalN = 6, canonicalProduct = 24, audit(n:sigma:phi:tau:jTwo:) + audit(_ result:) (LatticeInvariantResult overload). 두 변형 모두 nil 반환 = pass, InvariantViolation 반환 = fail 의 failures list 보유. hexa-ufo / hexa-aura / hexa-cern / hexa-rtsc / hexa-bio / hexa-chip 의 σ·φ = n·τ = J₂ = 24 invariant 자동 검증.

- edit:
  - project manifest 에 lattice audit 필드
  - cockpit project pane "lattice invariant" badge (σ·φ = 24 PASS/FAIL)
- exit:
  - alien-disc-mk1 + aura-clip-mk1 둘 다 σ·φ = 24 PASS (hexa-ufo / hexa-aura README 의 invariant 자동 검증)

라운드 4 — hexa-native parity surface (D80 sweep, κ-65)

G9. HexaNativeParityRef 8-field schema (D80 §4.1 contract)
- κ-65 (5e9f6dea): UfoVerifyRecord.swift 의 HexaNativeParityRef 가 connection-plan §4.1 의 8-field shape 으로 확장 — kernelPath / parityTest / parityMethod (7-case enum: substrateToSubstrate / analyticOracle / pythonCompanionSeedMatch / roundtripIdentity / heapqOracleExact / handMirroredPython / other) / parityTolerance (+non-numeric oracle note field) / parityStatus / hexaLangSHA / scopeNotes / relErr. 기존 (ref / relErr / tolerance) trio 는 on-disk JSON consumer 부재 audit 후 retire.
- deps: G5 (FalsifierEntry typed Codable pattern 전례)

  - ChipAnalyzeRecord (event_queue future consumer, noc_sim)
- exit:
  - 5 cell-record carrier 모두 8-field shape 으로 compile PASS
  - swift test 3/3 PASS (DependenciesLoaderTests)
G10. DependenciesLoader — 44-row cross-repo SSOT consumer
- κ-65 (5e9f6dea): Loaders/DependenciesLoader.swift 신규 — hexa-lang/domains/DEPENDENCIES.demi (44-row audit SSOT) 를 DemiParser 로 읽어 typed DependencyEntry 로 project. Weight / PortableStatus / Kind enum 이 .demi vocab mirror. inferGateType(for:) 가 §3.1/§3.2 contract 구현 (nonportable → hexaNativeAbsent, heavy-port → hexaNativeFuture). Path resolver 는 DEMIURGE_HEXA_LANG → DEMIURGE_REPO/../hexa-lang → ~/core/hexa-lang 순. Honesty floor: SSOT 부재 시 빈 array + stderr warning (no Swift hardcoded fallback, D86 g_no_hardcoded_data 준수, ProducerLoader 패턴 일치).

- exit:
  - testEmptyEnvironmentReturnsEmptyArray / testFixtureParsesFourRows WithEnumsAndKindSplit / testGateTypeInferenceContract PASS
G11. GateType.hexaNativeFuture (heavy-port bucket)
- κ-65 (5e9f6dea): GateType.swift 에 hexaNativeFuture case 추가 — 기존 hexaNativeAbsent (영구 부재) 와 분리. hexaNativeFuture 는 "포팅 예정, 무게 큼" (heavy-port) bucket — DependenciesLoader. inferGateType(for:) 가 PortableStatus.heavyPort row 를 여기로 매핑. hexaNativeBlocked predicate 가 두 case 모두 cover (G6/D80 cascade 의 honest cap). SkippedCellsDashboard color map: yellow (future) / orange (absent) — exhaustive switch 갱신.

κ-70 R9 closure entry (e818218) 의 'next horizon (κ-71+)' 약속 이행 — Round 10 scaffold 박음. 4 axis 묶음: (a) G39 4th cell candidate research 박제 (이번 cycle 동시 land · archive/session-notes/ 2026-05-22-k71-horizon-candidate-research.md cite) · (b) G40 4th cell pick + measured-oracle source 5-fold lock-in decision (κ-68 G27 / κ-69 G32 / κ-70 G36 동형 · pre-code decision gate · D120 자연 순서) · (c) G41 4th cell 첫 absorbed=true legitimate flip (κ-68 G29 / κ-69 G33 / κ-70 G37 mirror · MeasuredOracleRef schema 재사용 · invariantHolds record-type-agnostic audit 의 4th instance) · (d) G42 κ-71 closure 박제 (R10 4/4 LANDED · κ-70 R9 closure entry mirror). code 변경 0 — ARCH narrative 만 4 placeholder G-item 박는다. 각 항목 진행되면 [x] 로 박고 PLAN κ-71 entry + DESIGN.md D-block + 영향 파일 commit 으로 묶을 것. illustrative-physics gate (D106) 가 적용된 cell 은 본 round 의 absorbed flip 대상 아님 — RFC 013 §6.12 anti-conflation 유지.

κ-71 structural inflection (honest 박제): κ-70 의 Ufo 는 hexaNativeParity carrier 이면서 measuredOracle field 가 없는 마지막 1-field-extension 후보였다 (Aura G33 mirror · 최저 friction). 그 패턴이 κ-70 으로 소진 — 남은 유일 [HP][✗] carrier (FusionVerifyRecord) 는 D106 illustrative-physics 로 영구 잠김 (mc_transport · MeasuredOracleRef 부착 불가). 따라서 κ-71 의 어떤 후보도 κ-69/κ-70 의 "1-field 확장 = 최저 friction" 패턴을 재현 불가 — 모든 후보가 새 VerifyRecord 신설 (Bio/Chem) 또는 기존 record 재사용 + producer-side 새 sub-cell 경로 신설 (Energy/ wind) 중 하나. κ-71 critical-path 는 κ-68..κ-70 보다 substrate-side 또는 schema-side 한 단계 더 무겁다.

11.7 G43–G46 implementation checklist (κ-72 R11 · horizon round · scaffold)

라운드 11 — κ-72 R11 horizon round (scaffold · pre-code · framing TBD)

R11 status (2026-05-22): G43..G46 all [ ] · scaffold only · code 0. G43 framing decision is the first sub-gate — Framing A (G41 resumption · kernel refinement OR oracle-criterion D-block) · Framing B (5th cell · Bio/Chem/Matter NEW DOMAIN) · Framing C (hybrid · κ-72 = A · κ-73 = B). Recommendation in framing-research note = Framing A (advisory only · pick belongs to next session).

κ-71 R10 closure entry (c82fe0e PLAN log · 2ac28b4 G42 commit) 의 'next horizon (κ-72+)' 약속 이행 — Round 11 scaffold 박음. 본 round 의 G-shape 는 picked framing 에 의존:

Framing A picked (recommended): G43 = resumption-track decision (Path (i) kernel refinement vs Path (ii) oracle-criterion D-block · D122 자연 순서) · G44 = substrate refinement land OR D-block-only oracle relaxation · G45 = G41 first-flip 재시도 (D123 · 4th cell EnergyWindVerifyRecord 재사용 · 새 record 0) · G46 = R11 closure (4/4 LANDED if G45 PASS · 또는 PARTIAL 재현).

Framing B picked: G43 = 5th cell candidate research (κ-71 G39 mirror · Bio/Chem/Matter finalist) · G44 = 5th cell pick (D122 · κ-71 G40 mirror) · G45 = 5th cell first-flip (D123 · κ-71 G41 mirror · 5-record-type audit · PARTIAL risk 명시) · G46 = R11 closure.

Framing C picked: κ-72 G43..G46 = Framing A shape · κ-73 §11.8 (post-κ-72-closure) = Framing B shape.

code 변경 0 — ARCH narrative 만 4 placeholder G-item 박는다. 각 항목 진행되면 [x] 로 박고 PLAN κ-72 entry + DESIGN.md D-block (D122/D123 자연 순서) + 영향 파일 commit 으로 묶을 것. illustrative-physics gate (D106) 가 적용된 cell 은 본 round 의 absorbed flip 대상 아님 — RFC 013 §6.12 anti-conflation 유지.

κ-72 honest precedent inheritance: κ-71 R10 = 첫 PARTIAL 라운드 (3/4 + G41 [~]). 본 R11 의 어떤 framing 도 PARTIAL 가능성 명시 인정 — Framing A 의 G45 가 refined kernel 위에서 여전히 PASS 못해도 honest 3/4 + G45 [~] 가 정직한 land · Framing B 의 G45 가 새 record + 새 oracle 위에서 PARTIAL 도 동일. R4 invariant 가 작동하는 design 증거 · 실패 아님. 4/4 LANDED 는 결과이지 목표가 아니다 — 목표는 R4 의 정직한 land.

G41 [~] PARTIAL 상태 유지 (κ-72-A G45 시점까지): 본 §11.7 scaffold 가 land 되어도 §11.6 G41 의 [~] 는 그대로 · D121 도 그대로 · κ-72-A G45 가 PASS 시점에만 §11.6 G41 → [x] 로 flip. κ-72-B/C 채택 시 G41 indefinite [~] (B 채택 시 영구 · C 채택 시 κ-72-A 완결로 close).

12. Open axes (substrate-side · post-cell-flip)

This section tracks open work on substrate-side parity axes, running parallel to the per-cell measured-oracle round structure of §11.4. Each axis owns its own gate (g3 substrate · measurement_gate flip) and lands independently of the §11.4 G-rounds. ARCH §12 carries the narrative anchor + Tier-1/2/3 shape; detail SSOTs live in archive/session-notes/.

landing-axis distinction — D80 endpoint rule (§0): per-cell absorbed=true (e.g. chip §B+§D κ-43 dynamic flip) is a separate axis from the hexa-native parity port axis tracked here. A cell can be absorbed=true while its substrate-axis measurement_gate is still OPEN; the §12 axes close the latter without changing the former. Closure of a §12 axis removes the provisional=true demotion risk implied by §0, but is NOT itself a cell flip.

infrastructure-axis distinction — Many §12 substrate-axis measurements can route their heavy compute through the pool CLI infrastructure layer (e.g. chip §B substrate-axis ABC cross-platform reproducibility audit ran on ubu-2 per archive/session-notes/2026-05-21-pool-gate_v3-abc- diagnosis.md). Pool is a venue, not an endpoint — closing a §12 substrate-axis via pool dispatch still requires the hexa-native parity port to satisfy §0. Cross-link: POOL.md for the routing taxonomy + honest invariants + the _pool_cli_present canonical adapter precedent.

12.1 chip §B — rfc_006 §5 area-oracle parity (yosys absorption)

Moved 2026-05-22: this section's measurement state · Tier-1 closure sequence · multi-session progression · substrate-host infrastructure log was promoted to top-level ./YOSYS.md (spec) + ./YOSYS.log.md (campaign history). See those two files for the canonical Yosys absorption status. Detail SSOT remains archive/session-notes/rfc006-s5-area-oracle-parity-handoff.md.

Historical log entries are in ./ARCH.log.md.
