Nonlinear Static Newton–Raphson Coordination Record

1. Metadata and Feature Scope

• feature_id: nonlinear-static-newton-raphson
• workflow_state: needs-formulation
• owner_agent: coordinator-agent
• request_date: 2026-08-18
• last_updated: 2026-08-23 (Stage 2 사용자 명시 승인; Stage 3 Formulation Agent dispatch 준비)
• process_classification: architectural
• requested_capability: Newton–Raphson 방법을 사용하는 새 nonlinear static analysis procedure
• proposed_scope_boundary: 첫 release는 initial configuration 기준 Total Lagrangian, materially linear + geometrically nonlinear MITC4로 제한한다. 요구조건 인터뷰와 8단계 evidence gate를 먼저 완료하며, 승인 전에는 상세 수치·I/O·구현 범위를 확정하거나 기존 linear-static lifecycle을 변경하지 않는다.
• naming_note: 사용자 표현 Newton-Rhapson은 표준 명칭 Newton–Raphson으로 정규화했다.
• current_goal: 승인된 requirements.md와 사용자 승인된 research.md를 입력으로 Stage 3의 구현 가능한 formulation.md 계약을 Formulation Agent에게서 확보하고 독립 evidence audit을 수행한다.
• constraints: 승인된 physics/scope/tolerance/authoritative output/public compatibility를 보존한다. Stage 3는 O-ROT/O-MAP/O-DRILL/O-MOM/O-BC를 구현 가능한 수학 계약으로 해소하되 HDF5/I/O schema, reference artifact, C++/tests/CMake, phase/Harness 또는 Stage 4 판단으로 확장하지 않는다. Abaqus/Midas 내부 동등성을 주장하지 않는다.
• repository_audit: 기존 worktree에는 .codex/agents/*.toml과 AGENTS.md의 사용자 변경이 있으며 이를 보존한다.

Latest Sub-Agent Return

• target_sub_agent: research-agent
• output_paths: docs/nonlinear-static-newton-raphson/research.md
• status: passed (owner); needs-rework (user review gate)
• evidence_summary:
  • 17 external sources cover original MITC4/TL theory, finite rotation, objective/consistent linearization, Full Newton, V&V/MMS and nonlinear shell benchmarks.
  • B-01–B-06 invariant/software checks, B-07F/B-07M large-rotation cantilevers, public NAFEMS 3DNLG-1/9 candidates, locking characterization and shell-MMS gap are separated by applicability.
  • reference/shell/ and reference/shellR/ are explicitly retained as nlgeom=NO linear evidence; exact stored nonlinear input/CSV remains an honest Numerical Review gap.
  • Objective 24-DOF mapping/drilling, nodal-moment work, prescribed finite-rotation path, invariant tolerances and fixed-step benchmark traversability are routed downstream without inventing contracts.
• blockers:
  • User Stage-2 review/approval only.

5. Risk, Blocker, and User-Decision Register

id	type	description	owner	status
RISK-001	architecture	기존 LinearStaticAnalysis private lifecycle은 단일 factorization/substitution과 final frame만 소유하므로 nonlinear increment/iteration/state commit을 삽입하면 ADR 경계를 위반한다.	coordinator-agent routing	open
RISK-002	scope	Newton–Raphson은 solution algorithm이고 geometric/material/contact nonlinearity 범위를 단독으로 결정하지 않는다.	requirement-agent	mitigated by DECISION-001
RISK-003	contract	현재 Element는 displacement-dependent residual/consistent tangent/trial state 계약이 없고 AnalysisState는 nonlinear history를 소유하지 않는다.	downstream formulation/architecture gates	open
RISK-004	input	현재 NLGEOM=YES는 unsupported-nonlinear-geometry로 거부되고 *STATIC 네 값은 provenance로만 보존된다.	downstream requirements/I/O gates	open
RISK-005	verification	exact nonlinear reference artifacts와 path-dependent blocking quantities가 아직 지정되지 않았다.	downstream numerical-review gate	open
DECISION-001	user decision	첫 release는 materially linear + geometrically nonlinear MITC4로 고정한다. Material-only와 combined material/geometric nonlinearity는 이 release 범위 밖이다.	user via Coordinator	closed
DECISION-002	user decision	First-release geometric-nonlinear MITC4 kinematic framework는 initial configuration 기준 Total Lagrangian으로 고정한다. Updated Lagrangian과 corotational 의미는 이 release 범위 밖이다.	user via Coordinator	closed
DECISION-003	user decision	Newton variant는 Full Newton–Raphson으로 고정한다. 매 iteration의 current trial/candidate state에서 residual과 algorithmically consistent tangent를 재평가하고, 그 tangent로 새 factorization/solve를 수행한다. Modified Newton과 adaptive refresh는 out-of-scope다.	user via Coordinator	closed
DECISION-004	user decision	First-release nonlinear increment control은 하나의 scalar load coordinate/load factor로 approved load/BC path를 진행하는 Load-factor control로 고정한다. Controlled-displacement와 arc-length/path-following control은 out-of-scope다.	user via Coordinator	closed
DECISION-005	user decision	모든 approved *CLOAD와 nonzero prescribed *BOUNDARY target은 같은 dimensionless scalar load factor로 step-start 값에서 target까지 비례 진행한다. Fixed step-start BC와 independent/non-proportional amplitude/path는 out-of-scope다.	user via Coordinator	closed
DECISION-006	user decision	First-release는 approved fixed load-factor increment size를 반복하고 factor 1에 정확히 도달하도록 마지막 increment만 작게 조정하는 Fixed-size stepping으로 고정한다. Automatic growth, cutback/retry와 explicit schedule은 out-of-scope며 attempted increment failure는 재시도 없이 analysis failure다.	user via Coordinator	closed
DECISION-007	user decision	Nonlinear four-value *STATIC은 first positive value만 fixed load-factor increment로 사용하고 second/period는 exact supported endpoint 1을 요구하며 positive minimum/maximum은 입력 호환성을 위해 수용하지만 runtime stepping에는 사용하지 않는 First-value driven mapping으로 고정한다. Strict tuple과 single-value form은 out-of-scope다.	user via Coordinator	closed
DECISION-008	user decision	First-release approved *CLOAD force/moment component directions는 initial/current deformation과 무관하게 fixed global frame에 유지되고 common scalar factor로 magnitude만 비례 진행하는 dead-load semantics로 고정한다. Follower nodal loads, selectable dual semantics, external-load geometric tangent/follower work는 out-of-scope다.	user via Coordinator	closed
DECISION-009	user decision	Nonzero prescribed *BOUNDARY input value는 factor 1의 absolute global-DOF Total step target이며 step-start committed value에서 target까지 common scalar factor로 보간한다. Incremental delta와 selectable dual semantics는 out-of-scope다.	user via Coordinator	closed
DECISION-010	user decision	First release는 입력당 exactly one supported geometrically nonlinear static step만 허용하고 no-prior-history baseline에서 factor 0→1을 수행한다. Multiple nonlinear steps, mixed linear/nonlinear steps, cross-step state/load/BC propagation과 procedure transition은 out-of-scope/fail-closed다.	user via Coordinator	closed
DECISION-011	user decision	First-release increment acceptance는 free-DOF equilibrium residual과 Newton correction의 두 mandatory quantity가 각각 승인 gate를 모두 통과해야 한다. Energy convergence는 diagnostic/mandatory가 아닌 out-of-scope다. Norm, normalization과 tolerance는 별도 결정으로 남긴다.	user via Coordinator	closed
DECISION-012	user decision	Four channel-separated infinity gates의 nonzero-scale relative threshold는 각각 1e-2다. Zero denominator에는 own-channel absolute fallback을 적용하며 네 numeric literal은 모두 1e-3: force residual은 model-consistent force, moment residual은 force·length, translational correction은 length, rotational correction은 later-approved convention의 dimensionless rotation parameter다. .inp 단위 추론/변환은 하지 않는다.	user via Coordinator	closed
DECISION-013	user decision	First release는 No line search다. 각 successful fresh tangent correction solve의 full correction을 damping/backtracking/trial-step reduction 없이 next candidate에 그대로 적용하며 merit/acceptance/reduction loop, selectable input과 fallback은 out-of-scope/fail-closed다.	user via Coordinator	closed
DECISION-014	user decision	Attempted increment당 maximum Newton iteration count는 product-fixed 100이다. Entered iteration은 1..100; iteration 100 gate pass는 accept 가능하고 fail 시 iteration 101/candidate/retry/cutback 없이 immediate failure 및 prior committed state/result preservation을 적용한다.	user via Coordinator	closed
DECISION-015	user decision	MITC4 Newton solve는 dimensionless incremental rotation-vector correction을 만들고 authoritative rotational state는 orthonormal right-handed committed triad Q이며 director는 third axis다. Separate trial triad를 사용하고 large rotation은 multiplicative composition으로 갱신한다. Exact map/side/frame/parameterization/re-orthonormalization/drilling/derivatives는 downstream gap이다.	user via Coordinator	closed
DECISION-016	user decision	Successful analysis의 authoritative results.h5는 each committed nonlinear increment마다 exactly one accepted frame을 stable accepted-factor order로 저장하고 factor-1 frame을 포함한다. Trial/failed/duplicate/missing/partial-final history는 없으며 pre-existing valid final을 exact 보존한다. Exact schema와 factor-0 frame 여부는 downstream gap이다.	user via Coordinator	closed
DECISION-017	user decision	Every entered Newton iteration은 exactly one deterministic structured runtime summary를 낸다. Complete gate는 four-channel identities/norms/branch/threshold/pass/combined transition을 포함하고 early failure는 last-completed/failing stage와 later fields absent/not-evaluated를 기록한다. 이는 diagnostic-only이며 HDF5/sidecar/authoritative/reference quantity가 아니다. Transport/exit mapping은 별도 미결정이다.	user via Coordinator	closed
DECISION-018	superseded user decision	JSON Lines serialization family 결정은 DECISION-023 scope reversal로 current contract에서 retire되며 historical evidence로만 남는다.	user via Coordinator	closed
DECISION-019	superseded user decision	JSON stderr exactly-once emit/flush lifecycle 결정은 DECISION-023 scope reversal로 current contract에서 retire되며 historical evidence로만 남는다.	user via Coordinator	closed
DECISION-020	superseded user decision	JSON field-omission/not-evaluated-list 결정은 DECISION-023 scope reversal로 current contract에서 retire되며 historical evidence로만 남는다.	user via Coordinator	closed
DECISION-021	user operating policy	물리 결과·수치 거동·public compatibility에 실질 영향 없는 serialization notation/key ordering/diagnostic formatting 등 low-risk 기본 결정은 recommended option을 자동 적용한다. Formulation/Newton/state/tolerance/load-BC/input/failure-rollback/HDF5 authoritative/public compatibility/reference acceptance는 계속 한 번에 하나씩 인터뷰한다.	user via Coordinator	closed
DECISION-022	retired pending decision	JSON stderr write/flush failure policy는 DECISION-023 scope reversal로 선택 없이 retire되었다.	user via Coordinator	closed
DECISION-023	user scope reversal	JSON-specific runtime log decisions와 파생 contracts를 철회하고 serialization-independent OQ-011 granularity를 보존한 simple plain-text analysis log로 재설계한다. Destination은 stderr text 대 actual .txt file의 substantive user decision으로 남긴다.	user via Coordinator	closed
DECISION-024	user decision	Solver directly creates exactly one separate plain-text analysis-log file. Per-iteration summaries are file-only; stderr contains log open/write/close fatal diagnostic and final analysis failure summary only, with exact zero per-iteration duplication. External redirect and file+stderr duplication are excluded. Filename/location, overwrite and failure atomicity remain separate questions.	user via Coordinator	closed
DECISION-025	user decision	Repository-wide architectural direction approved: all existing/future analyses use input-directory <filename>.inp -> <filename>_results.h5 and <filename>_log.txt, and --output is removed. This requires later approved sectioned-design changes to ARCHITECTURE/ADR and cross-procedure regression evidence; no implementation/global-doc change is claimed now.	user via Coordinator	closed
DECISION-026	user decision	Every invocation containing --output, including the formerly valid explicit path form, fails before input parsing/Analysis construction/result-log creation with exact exit 2 and one ordered cli-usage stderr diagnostic. No compatibility alias or deprecation window.	user via Coordinator	closed
DECISION-027	user decision	Independent asymmetric lifecycle: current-run log replaces/truncates old log at invocation start and persists on success/failure; HDF5 uses sibling candidate and replaces final only after success, preserving prior valid final on failure; no cross-file pair atomicity.	user via Coordinator	closed
DECISION-028	user decision	Log-I/O grouped fail-closed policy: pre-analysis abort on create/open/truncate failure; immediate abort on write/flush; close failure blocks result commit; best-effort one fatal stderr diagnostic attempt, prior HDF5 and retained log prefix preservation, no retry/fallback/continue/result commit.	user via Coordinator	closed
DECISION-029	coordinator auto-default	OQ-034 low-risk plain-text representation/ordering: UTF-8 no BOM, one physical tab-separated label=value line per entered iteration, fixed semantic field/channel order, explicit not-evaluated(reason), locale-independent finite round-trip numerics, embedded control/backslash escaping. No physics/numerics/path/state/authority change.	Coordinator under DECISION-021	closed
DECISION-030	user decision	OQ-039 user-addressed lexical identity: resolve relative input against invocation CWD, lexically normalize ./.., do not resolve symlink/junction targets, accept final .inp case-insensitively, remove only the last extension and preserve preceding dots/basename case; output beside normalized user-addressed path.	user via Coordinator	closed
DECISION-031	superseded proposal	Same-derived-output concurrent invocation ownership의 fine-grained OQ-040 interview는 사용자 process correction으로 중단했다. 승인된 정책은 없으며 필요한 convention은 I/O/Planning owner가 repository evidence로 정한다.	user via Coordinator	closed
DECISION-032	user process decision	requirements.md를 핵심 Stage-1 계약으로 압축하고 OQ chronology, diagnostic/path/concurrency trivia와 반복 handoff를 제거한다. Minor details는 downstream specialist convention/evidence로 정하며 approved scope/physics/tolerance/public compatibility를 바꿀 때만 사용자 결정을 다시 요청한다.	user via Coordinator	closed
DECISION-033	design approval	Target 363 lines, 24 canonical requirements와 24-row Matrix, approved semantic-loss 0의 compact rewrite design.	user via Coordinator	closed
DECISION-034	user process decision	Requirement Agent는 approved physics/scope/tolerance/authoritative-output/public compatibility를 바꾸는 essential decision만 사용자에게 묻고, specialist detail은 owning downstream stage가 repository evidence와 conventional FEM practice로 정한다. Equivalence claim은 금지한다.	user via Coordinator; .codex/agents/requirement-agent.toml	closed
