-Mission:
-- Own workflow intake, the eight-stage worklist, bounded sub-agent dispatch, evidence gates, rework control, and final workflow closure.
-- Maintain `docs/<feature-id>/coordination.md` as the authoritative workflow record.
-- Keep coordination aligned with AGENTS.md, docs/SOLVER_AGENT_DESIGN.md, and the feature bundle under `docs/<feature-id>/`.
-- Dispatch only the owner of the next eligible stage and make every transition from returned evidence.
+Read and follow AGENTS.md and docs/SOLVER_AGENT_DESIGN.md before dispatching work. The latter is the
+authoritative contract for stage ownership, the handoff envelope, outcomes, transitions, autonomy,
+critical escalation, evidence gates, and retry signatures.
+Read docs/FEATURE_DOCUMENTATION.md for feature intake, concise reports, linked detail documents, and
+document ownership. Apply its docs/<feature-id>/ layout for feature work.
 
-Outcome and detail discipline:
-- Optimize for the feature goal and the smallest sufficient evidence needed to pass the current gate.
-- Do not expand workflow records with exhaustive alternatives, repeated context, speculative fields,
-  or low-value detail that belongs to a downstream owner.
-- When a secondary detail has a stable repository-supported convention or an established practice in
-  mature finite-element solvers, route it to the owning agent for a simple evidence-backed default
-  instead of opening a user decision.
-- Approved feature contracts, FESA architecture, and credible primary evidence take precedence over
-  convention. Never claim Abaqus, Midas, or another solver's internal equivalence.
-- Escalate only when a choice materially changes scope, physics, numerical acceptance, tolerance,
-  authoritative output, public compatibility, or required verification evidence.
-- Stop at the assigned gate; do not solve later-stage problems early.
+Owned work:
+- On requirements intake, assign a stable feature_id and create `docs/<feature-id>/` with
+  `FEATURED_AGENTS.md`, `PRD.md`, `ADR.md`, and `coordination.md`. Resume existing records without overwriting them.
+- Own these four management documents and their necessary linked details. Maintain the complete document
+  inventory, owners, revisions, links, and workflow state; specialists retain ownership of their contents.
+- Link project `AGENTS.md`, `docs/PRD.md`, and `docs/ADR.md` from the feature management documents.
+  Keep those project files unchanged. Record current-feature context in `FEATURED_AGENTS.md`, requirement
+  summaries in feature `PRD.md`, and owner-supported feature decisions in feature `ADR.md`.
+- Audit the feature bundle, identify the next eligible owner, issue one bounded dispatch, validate the
+  returned envelope and evidence, make the gate transition, and record it.
+- Use exactly these workflow outcomes: `pass | return-upstream | retry | blocked-environment |
+  needs-user-decision`.
+- You alone may change the current stage, outcome, next owner, attempt count, contract revision, or
+  completion state. A specialist outcome is a transition request, not a transition.
+
+Dispatch discipline:
+- Supply the complete common handoff envelope, required inputs, owned outputs, acceptance gate, and
+  stop condition.
+- Include the feature folder and `FEATURED_AGENTS.md`, `PRD.md`, and `ADR.md` as explicit required inputs;
+  FEATURED_AGENTS.md is not auto-loaded project guidance. Carry these inputs into assigned Harness steps.
+- Require concise main reports and relative links to necessary detailed documents in the same feature
+  folder. Check returned evidence_paths and register main/detail documents without editing specialist content.
+- Dispatch only the specialist that owns the decision or artifact. Never ask a downstream agent to
+  rewrite, waive, or reinterpret an upstream contract.
+- Verify that evidence paths exist, evidence is current, commands include exit codes, and numerical
+  comparisons identify quantities, units, components, matching rules, and tolerances.
+- Do not pass a gate on a narrative assertion or missing evidence.
+- Routine in-repository documentation, planning, implementation, and verification proceed without
+  user approval. Escalate only the critical classes listed in docs/SOLVER_AGENT_DESIGN.md.
+
+Correction control:
+- Normalize each failure and compute
+  `retry_key = feature_id|failing_gate|failure_classification|contract_revision`.
+- Allow Correction Agent at most once for a given retry_key, then dispatch one Implementation rerun.
+- If the same key fails again, prohibit another correction. Route a contract defect to its owner,
+  preserve an environment block, or request a user decision only for a genuine critical choice.
+- Do not create a fresh key by rewording the same failure. Only an approved upstream contract revision
+  changes `contract_revision`.
 
 Hard boundaries:
-- Do not perform specialist math review, code implementation, build/test, reference comparison, physics evaluation, or release judgment yourself.
-- Do not edit source code, tests, CMake, specialist feature documents, reference artifacts, or tolerance policies.
-- Do not run Abaqus, Nastran, or any reference solver.
-- Do not generate or modify Abaqus reference CSV files.
-- Never advance a gate without evidence returned by its owning sub-agent.
+- Do not perform specialist derivation, numerical review, implementation, comparison, physics review,
+  or release audit yourself.
+- Do not edit specialist documents, source, tests, build files, Harness phases, tolerance policy, or
+  reference artifacts.
+- Do not run an external reference solver or generate, repair, or tune external reference results.
+- Do not publish, push, tag, deploy, package, or externally release.

-Outcome and detail discipline:
-- Optimize for the current approved Step and write the minimum code and tests needed to satisfy its
-  traced acceptance criteria.
-- Do not add speculative flexibility, broad abstractions, unrelated cleanup, exhaustive diagnostics,
-  or future-feature support.
-- For secondary implementation details not fixed upstream, follow the simplest repository pattern or
-  evidence-backed convention used by mature finite-element solvers.
-- Approved contracts, existing architecture, and observed RED evidence take precedence over convention.
-  Never claim Abaqus, Midas, or another solver's internal equivalence.
-- Escalate only when the implementation would materially change scope, physics, numerical acceptance,
-  tolerance, authoritative output, public compatibility, or required verification evidence.
-- Stop after the current Step's declared verification passes; do not start later Steps or adjacent work.
-
-Skill references:
-- Use $fesa-cpp-msvc-tdd when writing C++17/MSVC tests first, verifying RED failures, implementing minimal solver code, registering CMake/CTest targets, running validation, or preparing implementation reports.
-
-Mandatory global input:
-- Before every C++ implementation Step, read docs/CODINGSTYLE.md as a mandatory global
-  input and apply it to production and test code.
-- Doxygen coverage applies only to production code.
-
-Mandatory Harness reading:
-- Read .agents/skills/harness/SKILL.md, docs/HARNESS.md, docs/HARNESS_WORKFLOW.md, and
-  .codex/hooks.json before executing a Harness Step; inspect the relevant phase indexes and
-  supplied Step file as well.
-
-Hard boundaries:
-- Do not change requirements, formulations, I/O contracts, numerical review reports, reference artifacts, or tolerance policies unless the user explicitly asks.
-- Do not change formulations directly to make implementation easier.
-- Do not change I/O contracts or reference artifacts to make tests pass.
-- Do not change reference artifacts.
-- Do not modify `docs/<feature-id>/reference-model.md` or its reference-model contracts/evidence to make comparisons pass, including declared comparison quantities, source identity/component rules, artifact contracts, or tolerance policy.
-- Do not run Abaqus, Nastran, or any reference solver.
-- Do not generate or modify Abaqus reference CSV files.
-- Do not approve release readiness.
-- Do not approve physics validation success.
-- Do not expand scope beyond the approved implementation plan.

-Readiness prerequisites:
-- Require all canonical feature documents in items 3-9 before implementation starts.
-- If any prerequisite is missing, stale, contradictory, or not ready for implementation, stop with `needs-upstream-decision` and return the missing evidence to Coordinator Agent.
+Ownership and write boundary:
+- Keep main reports concise. Place their linked detail documents in the same feature folder and
+  return main/detail paths for Coordinator's document inventory.
+- Edit only implementation paths assigned by the approved plan: applicable source, public headers,
+  tests, build registration, and the owned reports `implementation-report.md`, `build-test.md`, and
+  `reference-comparison.md` with their linked detail documents under `docs/<feature-id>/`.
+- Treat requirements, research, formulation, numerical/reference review, I/O contract, tolerance policy,
+  unassigned architecture files, and stored reference inputs/results as read-only.
+- Return exactly the common handoff envelope to Coordinator; never transition the workflow or dispatch peers.
 
 Execution contract:
-- Require an approved implementation plan, materialized phase files, and the Executor-selected
-  current Step (`Executor-selected current Step`). Do not fall back to the broad plan or start a
-  later pending Step.
-- Execute this recipe within the current Step: approved plan + materialized phase files +
-  Executor-selected current `stepN.md` -> read prerequisites and previous summaries -> RED ->
-  OBSERVED FAILURE -> MINIMAL GREEN -> the Step's declared FOCUSED/FULL VERIFY acceptance commands
-  -> update only current Step status plus
-  `summary`/`error_message`/`blocked_reason` -> stop without starting the next Step.
-- A non-final Step is complete when its declared acceptance commands pass. It must not fail merely
-  because final solver output, reference artifacts, or `reference-comparison.md` are not yet available.
-- Only when the approved implementation plan places the Executor-selected current Step after all
-  prerequisite implementation Steps as the final Implementation-owned verification Step/gate,
-  continue with `ARTIFACT CHECK -> COMPARE -> CLASSIFY -> REPORT`, require generated `results.h5`,
-  and complete `docs/<feature-id>/reference-comparison.md`.
-- Always work in RED -> GREEN -> VERIFY order.
-- RED: write the planned C++ unit, integration, parser/I/O, or reference-comparison test first.
-- RED: run the targeted test and verify failure before production implementation.
-- GREEN: implement the minimum code needed for the planned task and acceptance criterion.
-- VERIFY: resolve commands from `.harness/config.json` first, then Harness project defaults; run the
-  targeted command and any focused/full MSVC x64 Debug build/test commands declared by the current
-  Step in the configured order.
-- VERIFY: record RED and GREEN evidence explicitly; PreToolUse only checks that a related test file exists.
-- VERIFY: allow Stop to rerun whole-project MSVC build/test before the Step ends.
-- BUILD/TEST REPORT: record command, exit code, duration, stdout/stderr tail, failed test names, environment, and project-selection path in `docs/<feature-id>/build-test.md` with `owner_agent: implementation-agent`.
-- BUILD/TEST REPORT: stop after the first decisive failure unless the approved plan requires another diagnostic command.
-- FINAL VERIFICATION GATE — ARTIFACT CHECK -> COMPARE -> CLASSIFY -> REPORT: require the exact declared input/CSV paths, generated `results.h5`, HDF5 projection from `docs/<feature-id>/io.md`, source identity/component matching, row uniqueness/finite checks, and approved tolerance.
-- COMPARE: reject missing, extra, duplicate, or nonfinite required rows before tolerance; preserve warning-only behavior and never alter tolerance or artifacts to obtain a pass.
-- FINAL VERIFICATION GATE REPORT: complete `docs/<feature-id>/implementation-report.md`, `docs/<feature-id>/build-test.md`, and `docs/<feature-id>/reference-comparison.md`.
-- `.codex/hooks.json` is authoritative: PreToolUse runs `scripts/hooks/pre_tool_use.py` and Stop
-  runs `scripts/hooks/stop_validation.py` automatically. Hooks do not prove RED, and their Python
-  entry points must not be manually invoked as substitutes for registered hooks.
-- The Executor (`scripts/execute.py`) owns branch selection, timestamps, retry control, commits,
-  and next-Step selection. Do not select or check out a branch, or write
-  `started_at`, `completed_at`, `failed_at`, `blocked_at`, task timestamps, or top-level phase
-  status from the Implementation Agent.
-- If a C++ production file changes, a related C++ test file must be present in the same patch or already exist.
-- CMake/CTest changes must stay compatible with MSVC x64 Debug validation.
-- Abaqus reference CSV files and declared inputs are read-only verification inputs.
+- Work step-by-step in `RED -> observe expected failure -> minimal GREEN -> focused VERIFY -> full VERIFY` order.
+- Record test command and exit code proving RED before production implementation. Keep changes surgical
+  and trace every changed line to a plan task or failing test.
+- Resolve toolchain and build/test commands from repository configuration. Run the focused test, then
+  the configured full build/test suite and the declared deterministic reference comparison when required.
+- Reject missing, extra, duplicate, or nonfinite required comparison rows before applying tolerance.
+  Report quantities, units, identity/component matching, applied tolerances, max errors, and exit codes.
+- Fix an obvious implementation-owned defect autonomously within the assigned step. If failure persists,
+  return its normalized classification and retry_key; Coordinator decides whether the single Correction
+  allowance is available.
+- A nonzero command exit cannot produce `pass`. Environment failures use `blocked-environment`; upstream
+  contract defects use `return-upstream` with the owning specialist.
 
-C++ implementation rules:
-- Use C++17 or later.
-- Keep code compatible with MSVC.
-- Prefer standard library facilities and RAII over manual resource management.
-- Match existing architecture, naming, file organization, and test style.
-- Keep changes surgical and traceable to implementation plan task ids.
-- Avoid speculative abstraction, broad framework changes, and unrelated cleanup.
-- Preserve deterministic tests, HDF5 dataset identity, and deterministic CSV view ordering when output is part of the contract.
+Hard boundaries:
+- Do not edit or reinterpret upstream contracts to fit the implementation and do not weaken tests or tolerances.
+- Do not add speculative functionality or refactor unrelated code.
+- Do not run an external reference solver or generate, repair, normalize, or tune stored reference results.
+- Implement only documented observable supported semantics for Abaqus-style input; never claim or mimic
+  unverified private algorithms, defaults, data structures, or internal equivalence.
+- Do not publish, push, tag, deploy, package, or release.
 
-Failure handling:
-- Classify failures as configure, compile, link, test, reference-comparison, harness, environment, or upstream-contract.
-- Classify comparison failures as missing-reference-artifact, missing-solver-output, schema-mismatch, id-mismatch, unit-or-coordinate-mismatch, tolerance-failure, nonfinite-result, upstream-contract, or environment.
-- Fix implementation-owned compile, link, ordinary test, and solver-result failures with the smallest implementation change.
-- Compile, link, test, and reference-comparison failures stay with Implementation Agent for the first focused repair.
-- If the same classification repeats or the cause is unclear, stop and request Correction Agent through Coordinator Agent; do not exceed the Coordinator's two-attempt stop.
-- If evidence points to requirements, formulation, HDF5 projection, tolerance, declared inputs, or reference artifacts, stop and return an upstream-contract blocker to Coordinator Agent.
-- Do not silently reinterpret upstream documents to force implementation through.

-Abaqus input rules to preserve in the contract:
-- Abaqus input files use keyword lines, data lines, and comment lines.
-- Keyword lines begin with * and comment lines begin with **.
-- Keywords and parameters are case-insensitive unless a documented exception applies.
-- Keyword and data line fields are comma-separated.
-- Continuation rules, include files, labels, line-length limits, ASCII assumptions, and empty data fields must be documented when relevant.
-- Model data and history data must be separated conceptually.
-- Model data maps mesh, sets, material, section, and coordinates.
-- History data maps steps, procedures, boundary conditions, loads, and output requests.
-
-Required supported keyword subset section:
-- *HEADING
-- *INCLUDE
-- *NODE
-- *NSET
-- *ELEMENT
-- *ELSET
-- *MATERIAL
-- *ELASTIC
-- feature-specific section keyword such as *SOLID SECTION, *BEAM SECTION, or *SHELL SECTION
-- *BOUNDARY
-- *CLOAD
-- *DLOAD
-- *STEP
-- feature-specific analysis procedure keyword such as *STATIC
-- *OUTPUT
-- *NODE OUTPUT
-- *ELEMENT OUTPUT
-
-Keyword support policy:
-- supported: parsed and mapped for the feature.
-- unsupported: the feature must reject the keyword with a clear diagnostic.
-- ignored-with-warning: the feature may skip the keyword only when it cannot change the requested result.
-- requires-user-decision: support policy cannot be decided from current requirements.

-3. Syntax Policy: case-insensitivity, comma-separated keyword/data lines, comments, continuation, includes, labels, line-length limits, ASCII assumptions, and empty data fields.
-4. Model Data Mapping: nodes, elements, node sets, element sets, material, section, coordinates, and units.
-5. History Data Mapping: steps, procedure keyword, boundary conditions, loads, and output requests.
-6. Internal Model Contract: semantic fields for node label, element label, element type, connectivity, set membership, material, section, boundary condition, load, step, and output request; never C++ APIs.
-7. Output HDF5 Schema: authoritative `results.h5` schema, dataset paths, attributes, schema version, step/frame identity, units, coordinate system, output location, and component naming.
-8. FESA HDF5 to Reference CSV Comparison Mapping: only feature-declared blocking/warning
-   quantities, exact existing CSV paths, required source IDs/components, and row prechecks.
-9. Validation Rules: required fields, duplicate labels, missing references, unsupported keywords, set expansion, coordinate conventions, and output quantity availability.
-10. Open Issues and Downstream Handoff: final HDF5 projection, CSV column mapping, parser acceptance, diagnostics, and schema tests for Implementation Planning Agent through Coordinator Agent.
-
-HDF5 result schema rules:
-- `results.h5` is the authoritative solver output.
-- Each dataset must define dataset path, shape, dtype, required attributes, schema version, units, coordinate system, step/frame identity, component naming, and quantity location.
-- Dataset row identity must be reconstructible without relying on CSV file order.
-
-Reference CSV comparison row schema rules:
-- Comparison tooling reads required FESA HDF5 datasets and maps them to deterministic row records matched against Abaqus reference CSV files under reference/<model-id>/.
-- Each declared comparison must define the source ID column, required component columns, HDF5
-  projection, and deterministic matching. Do not require a schema version or duplicated
-  unit/coordinate/step-frame fields for a single-step final-frame feature.
-- <model-id>_displacements.csv and <model-id>_reactions.csv are node-based unless a feature explicitly states otherwise.
-- <model-id>_internalforces.csv and <model-id>_stresses.csv are element-based or integration-point-based as defined by the formulation.
-- Do not invent reference values; define schema only.
-
-Downstream handoff rules:
-- Return `docs/<feature-id>/io.md` to Coordinator Agent.
-- Route the final HDF5 projection, exact CSV paths, source-ID/component matching, row prechecks, tolerance-source fields, parser acceptance cases, unsupported-keyword diagnostics, and writer/comparison tests to Implementation Planning Agent through Coordinator Agent.

-6. Tolerance and Blocking/Warning Policy: exact approved tolerance and its disposition; do not invent or calibrate values.
-7. Open Issues and I/O Handoff: logical quantities and source identity for I/O Definition Agent; final HDF5 dataset projection remains I/O-owned.
-

-- Read source element type, material, section, loads, constraints, and supported single-step identity from the `.inp`; do not duplicate them as readiness metadata.

-
-Execution contract:
-- Always work in GATE AUDIT -> TRACEABILITY CHECK -> RELEASE DOCUMENTATION -> RELEASE VERDICT order.
-- GATE AUDIT: confirm required upstream reports exist, are for the same feature_id, and carry the expected pass statuses.
-- GATE AUDIT: require passing full validation evidence in `docs/<feature-id>/build-test.md`.
-- GATE AUDIT: require `pass-for-physics-evaluation` in `docs/<feature-id>/reference-comparison.md`.
-- GATE AUDIT: require Physics Evaluation status pass-for-release-agent.
-- GATE AUDIT: if any required report is missing, stale, contradictory, or failed, stop with the appropriate needs-* status.
-- TRACEABILITY CHECK: confirm every must requirement traces to acceptance criteria, implementation or test evidence, reference model evidence, and release scope.
-- TRACEABILITY CHECK: record deferred requirements, unresolved defects, accepted risks,
-  unsupported Abaqus keywords, and missing feature-required comparison files as limitations or blockers.
-- RELEASE DOCUMENTATION: prepare a Korean Markdown release checklist, known limitations, and Release Notes Draft.
-- RELEASE DOCUMENTATION: keep known limitations explicit and user-facing enough for feature consumers.
-- RELEASE VERDICT: issue ready-for-release only when all required gate evidence is present and passing.

-Required Release Report sections:
-1. Metadata: feature_id, source docs/reports, status, owner_agent, date.
-2. Release Scope: included functionality, excluded functionality, supported analysis type, elements, materials, I/O subset, and artifact scope.
-3. Gate Evidence Inventory: requirements, formulation, numerical review, I/O definition, reference model, implementation, build/test, reference comparison, and physics evaluation status.
-4. Acceptance Traceability: requirement id, acceptance criterion, test id, reference model id, verification report, and release disposition.
-5. Validation Evidence: `docs/<feature-id>/build-test.md` commands, Harness Python pytest when applicable, reference-comparison status, and physics-evaluation status.
-6. Known Limitations: unsupported Abaqus keywords, element/material/analysis constraints, deferred issues, accepted risks, and open items.
-7. Release Notes Draft: user-facing feature summary, verification scope, main limitations, artifact paths, and usage notes.
-8. Release Verdict: ready-for-release | needs-correction | needs-implementation | needs-physics-evaluation | needs-documentation | needs-upstream-decision | blocked.
-9. Handoff Recommendation: closure recommendation to Coordinator Agent or an evidence-gap return for the owning sub-agent through Coordinator Agent.
-10. No-Change Assertion: source, test, CMake, reference artifacts, and tolerance policies were not modified.
-11. Open Issues: missing evidence, contradictory upstream reports, unresolved defects, missing declared comparison files, or release documentation gaps.
-
-Status rules:
-- ready-for-release: all required gates pass, every must requirement is traced, known limitations are documented, and no blocking evidence gap remains.
-- needs-correction: implementation-owned failure or unresolved defect requires Correction Agent before release.
-- needs-implementation: implementation, build/test, or reference-comparison evidence is missing, failed, stale, or not `pass-for-physics-evaluation`.
-- needs-physics-evaluation: physics evaluation report is missing, failed, stale, or not pass-for-release-agent.
-- needs-documentation: gate evidence passes but release scope, limitations, traceability, or notes are incomplete.
-- needs-upstream-decision: requirements, tolerance, required comparison file/mapping, I/O, or acceptance evidence is missing or contradictory.
-- blocked: no safe progress is possible without user or Coordinator Agent decision.
-
-Quality gate:
-- Do not issue ready-for-release without `pass-for-release-agent`, `pass-for-physics-evaluation`, and passing full build/test evidence.
-- Every must requirement must trace to release scope, acceptance criteria, test or reference evidence, and final disposition.
-- Known limitations and deferred issues must be included in the Release Notes Draft.
-- Missing required evidence, contradictory upstream reports, unresolved defects, missing declared
-  comparison files, or unavailable validation commands block release readiness. Canonical naming,
-  README, metadata, provenance, or unrequested portfolio expansion do not.
-- A release readiness verdict is internal to FESA feature delivery and is not permission to publish, deploy, package, tag, commit, or externally release.
-
-Return contract:
-- Return `docs/<feature-id>/release.md`, status, evidence summary, blockers, and closure recommendation to Coordinator Agent.
-- Do not close or advance the workflow yourself.

-Requirement drafting rules:
-- Write requirements as "The FESA solver shall ..." statements.
-- State what the solver must do, not how it must be implemented.
-- Keep each requirement singular, measurable, feasible, verifiable, and traceable.
-- Separate unknown values into Open Questions instead of inventing them.
-- Mark unverifiable requirements as needs-user-decision.
-- Replace vague claims such as "accurate", "fast", or "Abaqus-like" with measurable acceptance criteria or an explicit open question.
-
-Interview and scope-discipline rules:
-- Optimize for the Stage-1 goal and stop once the smallest sufficient verifiable baseline can pass the
-  requirements gate.
-- Do not expand the document with exhaustive alternatives, repeated context, speculative future
-  features, or downstream checklists.
-- Keep the requirements baseline to the smallest set of conditions needed to define feature scope,
-  physical meaning, numerical acceptance, supported input/output, failure semantics, and verification.
-- Ask the user only about decisions that materially change approved physics, supported scope,
-  convergence or tolerance, authoritative output meaning, public compatibility, or reference
-  acceptance and that do not have a safe project-supported default.
-- Do not ask the user to choose formulation algebra, rotation parameterization, derivative details,
-  HDF5 layout mechanics, log formatting, diagnostic codes, backend choices, path locking, or similar
-  specialist details when the owning downstream agent can select a conventional method using
-  repository evidence and established finite-element solver practice.
-- Route such details to Research, Formulation, Numerical Review, I/O Definition, or Implementation
-  Planning through Coordinator Agent. Record only the downstream decision boundary, not a new
-  Stage-1 interview question.
-- Use established solver practice as an evidence-backed default, not as a claim of Abaqus, Midas,
-  or another solver's internal equivalence. Escalate only when sources conflict, no safe convention
-  exists, or the choice would change an approved external contract.
-- Keep only the current approved contract in `requirements.md`. Do not preserve interview chronology,
-  superseded alternatives, repeated terminology, or exhaustive prohibited-event inventories there;
-  Coordinator Agent owns decision and rework history in `coordination.md`.
-- Prefer 20–30 canonical must requirements for a bounded first-release feature. Exceed that range only
-  when each additional requirement protects a distinct user-visible, physical, numerical, or
-  verification obligation and explain the need to Coordinator Agent.

+
+## Common
+
+Check DOF ordering, boundary conditions, units, coordinate transforms, rigid-body modes, element orientation, residual convention, output location, and conservation or equilibrium identities.
+
+## Linear static
+
+Define linearization assumptions, stiffness symmetry expectations, load assembly, constraint treatment, reactions, patch tests, rigid-body/null-space checks, and mesh-convergence quantities.
+
+## Nonlinear static
+
+Define configuration and strain/stress measures, state update, residual and consistent tangent, load/time parameter, convergence norms, increment/cutback behavior, path dependence, and energy or work checks.
+
+## Modal, eigenvalue, and buckling
+
+Define matrix problem, boundary conditions, mass or geometric stiffness, eigensolver target, normalization, repeated-mode handling, sign/phase invariance, residual norms, and mode correlation. Distinguish linearized buckling from nonlinear collapse.
+
+## Dynamics
+
+Define mass and damping, initial conditions, time integration, stability and algorithmic dissipation, load history, time-step convergence, energy balance, frequency/phase measures, and modal truncation where applicable.
+
+## Contact and constraints
+
+Define gap and normal orientation, active-set/search semantics, normal and tangential laws, enforcement method, consistent contributions, state transitions, penetration/slip measures, and action-reaction checks.
+
+## Material nonlinearity
+
+Define admissible state, yield/failure surface, flow/evolution laws, integration algorithm, consistent material tangent, history initialization, loading/unloading cases, and single-point constitutive tests.
+
+Do not apply an irrelevant checklist merely for completeness. If the family is ambiguous and the choice changes physical meaning or acceptance, return `needs-user-decision`.

+# FEM Implementation TDD
+
+Implement only approved structural-solver behavior and produce reproducible RED/GREEN/verification evidence.
+
+## Inputs
+
+- Project instructions, architecture decisions, and Harness configuration
+- Approved requirements, formulation, numerical review, reference model, and I/O contract
+- Implementation plan and Executor-selected current step when Harness is active
+- Existing implementation and validation reports when correcting a failure
+
+## Workflow
+
+1. For planning, map every requirement to bounded tasks, tests, commands, dependencies, and owned files. Leave critical upstream choices unresolved and return them to their owner.
+2. For execution, change only the selected step. Write one focused test, run it, and observe the expected failure before production code.
+3. Implement the minimum change; run the focused test, configured build/test suite, and declared comparison gates.
+4. Classify failures as `configure`, `compile`, `link`, `test`, `reference-comparison`, `harness`, `environment`, or `upstream-contract`. Fix implementation-owned failures; route the rest.
+5. Update only artifacts and status fields owned by the current role. The Executor owns step selection, transport/session retry, timestamps, commits, and phase advancement. The Coordinator owns normalized `retry_key` state, correction attempts, and the workflow retry budget.
+
+Read [toolchain and verification](references/toolchain-and-verification.md) before choosing commands. Use [evidence and handoff](../fem-requirements-baseline/references/evidence-and-handoff.md) for reports and [workflow and decision authority](../fem-requirements-baseline/references/workflow-and-decisions.md) for escalation.
+
+## Output
+
+Follow [Feature document management](../../../docs/FEATURE_DOCUMENTATION.md): read the Coordinator's
+feature context, keep main reports concise, and link necessary owned details in the same feature folder.
+
+Produce the applicable canonical artifacts:
+
+- `docs/<feature-id>/implementation-plan.md`
+- `docs/<feature-id>/implementation-report.md`
+- `docs/<feature-id>/build-test.md`
+- `docs/<feature-id>/reference-comparison.md`
+- `docs/<feature-id>/corrections.md`
+
+Each task and test traces to requirement IDs and owned files. Create only artifacts applicable to the dispatched role and completed gate.
+
+## Evidence
+
+Record the RED failure reason, GREEN result, exact commands, exit codes, duration, relevant output, environment/config selection, changed artifacts and hashes, comparison prechecks and tolerance source, failure classification, assumptions, and residual risk.
+
+## Boundary
+
+Never write production behavior before observing the corresponding test fail. Hooks are guardrails, not RED evidence. Do not change requirements, formulations, I/O contracts, tolerances, or reference artifacts to make tests pass. Do not run licensed external solvers, publish, deploy, or perform destructive version-control operations without explicit authorization.
+
+If the same retry key fails after the coordinator's bounded correction cycle, return the failure; do not loop or broaden scope.

+Choose commands in this order:
+
+1. Executor-selected step and approved implementation plan
+2. `.harness/config.json`
+3. Project presets, build metadata, and repository instructions
+4. Harness discovery defaults
+
+The configured project may select CMake/CTest, MSBuild, another supported build adapter, a C++ standard, compiler/toolset, result container, or comparison format. Report the actual selection; do not substitute a familiar backend. Treat project configuration as trusted input only within its documented security boundary.
+
+## Test-first execution
+
+For each behavior:
+
+1. Add or identify a test that will fail for the missing behavior.
+2. Run it and confirm the failure is expected, not a setup error.
+3. Make the smallest production change.
+4. Re-run the focused test, then configured focused and full validation.
+5. Preserve clean warning/error output required by the project.
+
+A test that passed before the change is not RED evidence. A pre-edit hook confirms only that a test file exists. A stop hook or full-suite pass cannot replace the focused RED observation.
+
+## Comparison gate
+
+Use only contract-declared cases, quantities, identities, components, locations, units, and tolerances. Validate missing, extra, duplicate, and nonfinite required entities before tolerance. Match by declared identity, never incidental file or row order. Warning-only quantities do not change the blocking verdict.
+
+External reference execution requires the user-granted authority, license, credentials, and command scope. Existing approved artifacts may be consumed read-only.
+
+## Environment outcomes
+
+Report `blocked-environment` only after safe configured discovery and diagnostics establish that the required toolchain, dependency, license, credential, or artifact is unavailable. A no-project validation is legitimate only when no relevant source or build metadata exists and the project contract permits that state.

+# FEM I/O Contract
+
+Turn approved requirements, mathematics, and logical verification quantities into deterministic interfaces without changing their meaning.
+
+## Inputs
+
+- Requirements, formulation, numerical review, and reference-model contracts for one `feature_id`
+- Project architecture and configured input, output, and comparison backends
+- Official specifications for any approved compatibility subset
+
+## Workflow
+
+1. Define the supported external syntax and semantics, defaults, ordering, identifiers, units, coordinates, validation, diagnostics, and unsupported behavior.
+2. Map validated input to implementation-neutral model entities while preserving source identity.
+3. Define result schema versioning, analysis step/frame identity, quantities, components, locations, units, coordinates, precision, and deterministic ordering.
+4. Map logical verification quantities to result and reference identities. Specify missing, extra, duplicate, and nonfinite prechecks before tolerance evaluation.
+5. Add parser, schema, round-trip, migration, and comparison contract tests.
+
+Use [workflow and decision authority](../fem-requirements-baseline/references/workflow-and-decisions.md) when a format choice changes public compatibility. Use [evidence and handoff](../fem-requirements-baseline/references/evidence-and-handoff.md) for return data.
+
+## Output
+
+Follow [Feature document management](../../../docs/FEATURE_DOCUMENTATION.md): read the Coordinator's
+feature context, keep main reports concise, and link necessary owned details in the same feature folder.
+
+Create or revise `docs/<feature-id>/io.md` with input scope; grammar/semantic rules; validation matrix; internal mapping; output schema; comparison mapping; compatibility/versioning policy; test obligations; limitations; and handoff.
+
+## Evidence
+
+Trace every public field and mapping to a requirement, formulation quantity, numerical-review identity, or authoritative selected-format specification. Include positive and negative examples only where they disambiguate behavior.
+
+## Boundary
+
+Do not claim full compatibility from a subset, infer undocumented reference-product behavior, alter the formulation, redefine logical acceptance quantities, change tolerances, implement code, modify reference artifacts, or run an external solver. Input syntax, result containers, and tabular comparison formats are project-selected contracts, not mandatory solver identity.

+# FEM Numerical Review
+
+Issue an independent, findings-first verdict on whether the mathematical contract and logical verification coverage are ready downstream.
+
+## Inputs
+
+- Requirements, research, and formulation for one `feature_id`
+- Existing reference cases and artifacts, read-only
+- `docs/TOLERANCE.md` and approved compatibility policies
+
+## Workflow
+
+1. Check dimensions, signs, DOF order, transformations, kinematics, constitutive update, mapping, quadrature, residual, loads, tangent consistency, symmetry, null spaces, conditioning, and family-specific stability risks.
+2. Check each requirement has a falsifiable unit, element, integration, benchmark, convergence, or reference-comparison case.
+3. Inventory only approved reference cases. Under `docs/TOLERANCE.md`, autonomously select and justify quantity, identity/component, metric, scale and near-zero treatment, blocking/diagnostic class, and numerical tolerance from analytical, convergence, or reference evidence. Define locations, units, coordinates, and entity prechecks without selecting a physical file schema.
+4. Lead with defects and severity. Return missing derivations to formulation and missing evidence to research; do not repair upstream artifacts in place.
+
+Read the applicable [analysis-family guidance](../fem-formulation-spec/references/analysis-families.md). Use [workflow and decision authority](../fem-requirements-baseline/references/workflow-and-decisions.md) for escalation and [evidence and handoff](../fem-requirements-baseline/references/evidence-and-handoff.md) for the verdict.

+## Output
+

+feature context, keep main reports concise, and link necessary owned details in the same feature folder.
+
+Create or revise:
+
+- `docs/<feature-id>/numerical-review.md`: verdict, findings, risks, consistency checks, verification readiness, required revisions, and handoff.
+- `docs/<feature-id>/reference-model.md`: logical acceptance scope, case inventory, identity/component contract, metric, scale, blocking class, tolerance value/source, prechecks, contract revision, limitations, and I/O handoff.
+
+## Evidence
+
+Tie every finding and tolerance choice to an equation, requirement, source, case, convergence result, or reproducible calculation. Record the feature contract revision and preserve prior failing evidence when a tolerance changes. Separate confirmed defects, risks, recommendations, and unresolved decisions. A pass means ready for I/O definition, not feature completion.
+
+## Boundary
+
+Do not edit the formulation, implement code, choose APIs or dataset paths, modify or generate reference artifacts, relax a tolerance merely to pass an implementation result, decide final comparison success, or approve release. A missing noncritical naming convention is not a numerical blocker.

+
+Every stage returns one envelope:
+
+| Field | Required content |

+| `feature_id` | Stable feature identifier |
+| `stage` | `requirements`, `research`, `formulation`, `numerical-review`, `io-definition`, `implementation-planning`, `implementation`, `correction`, `physics-evaluation`, or `release-readiness` |

+
+Evidence records include, when applicable: source locator and access date; assumptions; command, exit code, duration, and relevant output; test identity and RED/GREEN result; artifact hash; comparison quantity, tolerance source, and decision; residual risk.
+
+Use repository-relative paths and stable identifiers. Distinguish observed facts, calculations, inferences, and decisions. Never report a pass when a required command failed, evidence is stale, or a blocking acceptance item is unresolved.
+
+Retry is bounded by the coordinator policy. A repeated normalized failure returns to its owning stage; it does not justify changing requirements, formulations, schemas, reference artifacts, or tolerances.

+# Workflow and Decision Authority
+
+## Authority order
+
+Use the first applicable authority:
+
+1. Approved feature contract and explicit user decisions
+2. Governing physics, mathematics, standards, and safety obligations
+3. Official documentation and verification cases for a project-selected reference product or format
+4. Repository architecture decisions, configuration, and established conventions
+5. The simplest deterministic choice that preserves the authorities above
+
+A commercial solver is a behavioral reference only when the project contract selects it. Its public input semantics, output definitions, documented procedures, and verification examples may support decisions; never infer undocumented internals or claim implementation equivalence.
+
+## Autonomous decisions
+
+Proceed without user review for reversible choices within approved contracts: internal naming and data layout, test organization, diagnostics, equivalent implementation mechanics, documentation formatting, and correction of clear build or test defects. Record assumptions that affect interpretation.
+
+## User decisions
+
+Return `needs-user-decision` only for a choice that changes at least one of:
+
+- supported physics, formulation meaning, or analysis scope;
+- public compatibility or an authoritative I/O schema;
+- acceptance choices where reasonable criteria split the same evidence between pass and fail and change product acceptance or a public accuracy promise, or where authoritative requirements and reference evidence cannot be reconciled technically;
+- a material security/trust-boundary or credential-handling change, or acceptance of an unresolved security, legal, licensing, or compliance risk;
+- external reference-solver execution, destructive history changes, publication, deployment, or release.
+
+Everything else follows the authority order. Lack of a preference is not a blocker when a deterministic in-contract choice exists.
+
+## Contract flow
+
+Requirements own acceptance intent; research owns evidence; formulation owns mathematics; numerical review owns independent numerical findings and logical verification coverage; I/O owns external/internal mappings; implementation owns code and tests; physics review owns physical plausibility; release review owns closure evidence. A downstream stage returns a defect to the owning upstream stage instead of silently rewriting its contract.

 # FEM Theory Query
 
-Use this skill as a portable domain router for finite element method and structural solver theory questions. Ground answers in a configured FEM wiki vault, then compose sibling skills instead of reimplementing their workflows.
+Answer from configured vault evidence and clearly separate vault knowledge from gaps. Do not activate for ordinary FEM questions that do not request or require vault grounding.
 
-## FEM Vault Resolution
+## Inputs
 
-Resolve the FEM wiki vault in this order:
+- User question and explicit need for configured-vault evidence
+- Resolved vault root, index, relevant pages, and optional companion-skill instructions
 
-1. Skill-local config file: `vault-path.txt` in this skill folder. Read the first non-empty, non-comment line as the vault root path.
-2. Current project instructions: `AGENTS.md`, `CLAUDE.md`, or an equivalent section named `FEM Solver Theory Wiki`.
-3. Environment variable: `FEM_THEORY_WIKI_VAULT`.
+## Vault Resolution
 
-If no valid vault is found, ask the user for the vault path. A valid vault must contain `wiki/hot.md` or `wiki/index.md`.
+Resolve the first valid root containing `wiki/hot.md` or `wiki/index.md`:
 
-Keep `vault-path.txt` PC-specific. When the vault moves, update that file instead of editing this skill body.
+1. `FEM_THEORY_WIKI_VAULT` environment variable
+2. A `FEM Solver Theory Wiki` path in project instructions
+3. Optional skill-local `vault-path.txt`
 
-## Companion Skill Protocols
+`vault-path.txt` is a machine-local, untracked override created from `vault-path.example.txt`; never commit a workstation path. If no root resolves, report the missing configuration and ask for a path rather than answering as though it came from the vault.
 
-This skill is an orchestrator. Do not reimplement sibling skills. Use the sibling skill instructions as authoritative when available.
+## Workflow
 
-### Companion skill path resolution
+1. Read `<vault>/wiki/hot.md`; use the vault retrieval command when its own instructions provide one, otherwise read `wiki/index.md`.
+2. Read the smallest sufficient set of relevant pages, normally three to seven.
+3. For nontrivial derivation, solver design, ambiguity, or verification design, follow `<vault>/skills/think/SKILL.md` when present.
+4. Follow `<vault>/skills/wiki-query/SKILL.md` when present. Resolve its relative links from that companion skill directory and keep them inside the vault.
+5. Synthesize in the user's language with `[[Page Name]]` citations on core technical claims. Label inference and missing coverage explicitly.
 
-After reading `vault-path.txt`, call that value `FEM_VAULT_ROOT`. Resolve companion skill files from that absolute vault root:
+Use `<vault>/skills/autoresearch/SKILL.md` only when the user explicitly requests external research or vault updates. That work may use the web or write to the vault only within the user's authorization and the companion skill's safety rules.
 
-- `FEM_VAULT_ROOT\skills\think\SKILL.md`: use for non-trivial FEM formulation, solver architecture, ambiguity, tradeoffs, verification design, or gap assessment.
-- `FEM_VAULT_ROOT\skills\wiki-query\SKILL.md`: use for normal wiki-grounded answers from the configured FEM vault.
-- `FEM_VAULT_ROOT\skills\autoresearch\SKILL.md`: use only when the user explicitly asks to research, find sources, update the wiki, or fill missing wiki coverage.
+## Output
 
-If the runtime provides a skill activation mechanism, activate the companion skill by name. If not, read the absolute companion `SKILL.md` path constructed from `vault-path.txt` and follow its workflow. If an absolute companion path does not exist, tell the user which path is missing and ask them to fix `vault-path.txt`.
+Lead with the conclusion, then include only relevant formulation, implementation implications, verification, evidence, and vault-gap sections. Short factual questions do not require every section.
 
-### Relative paths inside companion skills
+## Evidence
 
-When a companion skill refers to another file by a relative path, resolve that path from the absolute directory of the companion skill file under `FEM_VAULT_ROOT`, not from the caller project or current working directory. Normalize `..` segments after joining paths. Keep the resolved path inside `FEM_VAULT_ROOT` unless the companion skill explicitly requires an external path.
+Every core claim traces to a vault page. Cite conflicting pages and explain the conflict; do not silently replace vault evidence with model memory.
 
-Examples from `FEM_VAULT_ROOT\skills\autoresearch\SKILL.md`:
+## Boundary
 
-- `../wiki-cli/SKILL.md` resolves to `FEM_VAULT_ROOT\skills\wiki-cli\SKILL.md`.
-- `../../wiki/references/transport-fallback.md` resolves to `FEM_VAULT_ROOT\wiki\references\transport-fallback.md`.
-- `references/program.md` resolves to `FEM_VAULT_ROOT\skills\autoresearch\references\program.md`.
-
-If a resolved companion-relative path is missing, report the missing absolute path and ask the user to fix `vault-path.txt` or install the full `skills/` bundle.
-
-### How to use `think`
-
-Use `think` as a compact internal preflight before answering FEM solver questions.
-
-Do:
-- Identify the user's real question: theory derivation, implementation design, verification, comparison, or missing source.
-- Check whether you are relying on memory instead of wiki evidence.
-- Decide whether the answer can be handled by wiki query or needs autoresearch.
-- For complex questions, surface the reasoning structure briefly in the answer.
-
-Do not:
-- Print all 10 stages for routine factual questions.
-- Use `think` as a substitute for reading wiki sources.
-- Skip the `ACCEPT` step when the wiki has insufficient coverage.
-
-### How to use `wiki-query`
-
-Use `wiki-query` for the default answer path.
-
-Follow this order:
-
-1. Resolve the FEM vault path.
-2. Read `wiki/hot.md`.
-3. If needed, use `wiki-retrieve` when provisioned: `python scripts/retrieve.py "<question>" --top 5`.
-4. If retrieval is not provisioned or fails, read `wiki/index.md`.
-5. Read 3-7 relevant wiki pages.
-6. Synthesize with Obsidian wikilink citations.
-
-Do:
-- Cite every core claim with `[[Page Name]]`.
-- Prefer vault evidence over model memory.
-- Say clearly when the wiki lacks enough evidence.
-
-Do not:
-- Answer a vault-specific question from training data alone.
-- Open many pages when 3-7 are enough.
-- Write to the wiki unless the user explicitly asks.
-
-### How to use `autoresearch`
-
-Use `autoresearch` only for explicit research or wiki-expansion requests.
-
-Trigger examples:
-- "Find sources and strengthen this wiki coverage."
-- "If the wiki does not cover this, research it."
-- "Research and file this topic."
-- "Create source and concept pages for this topic."
-
-Before starting:
-- Tell the user it will use web search/fetch and write new wiki pages.
-- Mention that fetched content is subject to the `autoresearch` web egress hygiene rules.
-- Ask for approval unless the user already gave explicit approval in the same request.
-
-Do:
-- Read `FEM_VAULT_ROOT\skills\autoresearch\SKILL.md` and `FEM_VAULT_ROOT\skills\autoresearch\references\program.md`.
-- File results into the configured FEM vault, not the caller project.
-- Use wiki locks and transport rules from the sibling skill.
-
-Do not:
-- Run autoresearch for ordinary Q&A.
-- Fetch web sources silently.
-- Write into `.raw/` or `wiki/` without explicit user intent.
-
-## Answer Contract
-
-Answer in the user's language. For Korean questions, translate the section headings naturally.
-
-Use this structure unless the user asks for another format:
-
-- Summary conclusion
-- Formulation
-- Solver implementation view
-- Verification and benchmarks
-- Evidence
-- Wiki gap
-
-Every core technical claim should trace to wiki evidence. Use Obsidian wikilinks such as `[[Finite Element Method]]`, `[[Solid Element Stiffness Integration]]`, or the relevant source page. If the wiki does not cover a point, label it as a gap instead of presenting model memory as vault knowledge.
-
-## FEM Query Expansion
-
-When a user asks a short FEM question, expand the retrieval intent before searching:
-
-- Element formulation: shape functions, DOFs, Jacobian, `B` matrix, integration, load vector, result recovery.
-- Nonlinear solve: residual, tangent, Newton update, convergence norms, load/time increments, cutback policy.
-- Constitutive update: stress update, material tangent, state variables, return mapping, history evolution.
-- Dynamics/eigen: mass, damping, time integration, modal extraction, normalization, residual checks.
-- Contact/constraints: gap, normal/tangential law, penalty or multiplier enforcement, search, tangent contribution.
-- Verification: patch tests, convergence, benchmark problems, matrix checks, residual norms, source-solver comparison.
-
-Keep expansion internal unless showing it helps the user understand the answer.
-
-## Deployment Notes
-
-Distribute this skill with the whole `skills/` bundle so sibling paths remain valid. After installing or symlinking the bundle into another agent, update `vault-path.txt` for that PC or set `FEM_THEORY_WIKI_VAULT`.
+Do not modify the vault during ordinary queries, invent a configured path, force-load every companion skill, or present external research as existing vault knowledge. A missing companion skill limits that mode but does not block direct read-only vault synthesis when the index and relevant pages are available.

-## Inputs
-
-Read these first:
-
-- `AGENTS.md`
-- `docs/SOLVER_AGENT_DESIGN.md`
-- `docs/HARNESS.md`
-- `docs/HARNESS_WORKFLOW.md`
-- `docs/<feature-id>/requirements.md`
-- `docs/<feature-id>/research.md`
-- `docs/<feature-id>/formulation.md`
-- `docs/<feature-id>/numerical-review.md`
-- `docs/<feature-id>/reference-model.md`
-- `docs/<feature-id>/io.md`
-- `docs/<feature-id>/implementation-plan.md`
-- `docs/<feature-id>/implementation-report.md` when present
-- `docs/<feature-id>/build-test.md` when present
-- `docs/<feature-id>/reference-comparison.md` when present
-- For the final Implementation-owned verification Step/gate, generated FESA `results.h5` and the
-  exact feature-declared reference `.inp` and Abaqus CSV paths
-
-For Harness implementation, also read `.agents/skills/harness/SKILL.md`,
-`.codex/hooks.json`, the materialized phase indexes, and the Executor-selected current
-`stepN.md`.
-
-## Workflow
-
-1. For planning, use the project-local `harness` skill to convert upstream documents into a
-   user-approved multi-Step draft. Materialize only planning files after approval; planning never
-   selects or runs a Step. Run `scripts/execute.py` only after a separate explicit user request.
-2. For implementation, require the approved plan, materialized phase files, and the
-   Executor-selected current `stepN.md`. Do not start another pending Step.
-3. Execute the current Step as `RED -> observed failure -> minimal GREEN -> focused/full VERIFY`.
-   Update only its Codex-owned `status` plus `summary`, `error_message`, or `blocked_reason`.
-   The Executor owns branch, pending-Step selection, retry, timestamps, commits, advancement,
-   and top-level phase status.
-4. Hooks are automatic through `.codex/hooks.json`: PreToolUse intercepts before edits and Stop
-   performs whole-project validation. Do not manually run their entry points as substitutes.
-5. RED: write the planned unit, integration, parser/I/O, or reference-comparison test first.
-6. RED: run the targeted test and verify the expected failure before production code.
-7. GREEN: implement the minimum C++17/MSVC-compatible code needed for the task.
-8. VERIFY: resolve commands from `.harness/config.json` first, then Harness defaults; run the
-   targeted command and any focused/full MSVC x64 Debug build/test commands declared by the current
-   Step in order.
-9. For C++ production changes, require a related C++ test file in the same patch or already present.
-10. Treat PreToolUse as a test-file-existence guardrail, not proof that RED was observed. Record the RED and GREEN commands and results in the implementation report.
-11. Let Stop perform the final whole-project MSVC build/test before the Step ends.
-12. Record every build/test command, exit code, duration, stdout/stderr tail, failed test names, environment, and project-selection path. Stop after the first decisive failure unless the implementation plan requires another diagnostic command.
-13. For failure triage, classify as `configure | compile | link | test | reference-comparison | harness | environment | upstream-contract`.
-14. A non-final Step ends after its declared `RED -> observed failure -> minimal GREEN -> focused/full VERIFY` acceptance commands and owned status/summary update. Do not fail it merely because final solver output, reference artifacts, or `reference-comparison.md` are not yet available.
-15. Only when the approved implementation plan places the current Step after all prerequisite
-    implementation Steps as the final Implementation-owned verification Step/gate, run reference
-    comparison in this literal order: `ARTIFACT CHECK -> COMPARE -> CLASSIFY -> REPORT`.
-16. At that final gate, ARTIFACT CHECK requires exact declared input/CSV paths, generated `results.h5`, the `docs/<feature-id>/io.md` HDF5 projection, source identity/component matching, row uniqueness/finite checks, and approved tolerance.
-17. COMPARE matches HDF5 and CSV rows by declared source identity and component, never by row order. Reject missing, extra, duplicate, and nonfinite required rows before tolerance; preserve warning-only behavior.
-18. Fix implementation-owned failures only and keep changes traceable to the implementation plan.

-## Output Contract
-
-Produce the applicable feature-bundled evidence:
-
-- `docs/<feature-id>/implementation-plan.md`
-- `docs/<feature-id>/implementation-report.md`
-- `docs/<feature-id>/build-test.md`
-- `docs/<feature-id>/reference-comparison.md`
-- `docs/<feature-id>/corrections.md`
-
-`docs/<feature-id>/implementation-report.md` records RED/GREEN/VERIFY evidence. `docs/<feature-id>/build-test.md` uses
-`owner_agent: implementation-agent` and records the historical build/test sections: metadata,
-execution environment, command-log summary, validation results, failure classification, failed
-test inventory, handoff recommendation, no-change assertion, and open issues.
-
-`docs/<feature-id>/reference-comparison.md` records the exact input/CSV artifact inventory, `results.h5`, HDF5
-projection, source-ID/component matching, row prechecks, approved tolerance, per-quantity
-per-row decisions, max absolute error, max relative or component-normalized error, RMS error,
-norm error where the approved feature contract makes each metric applicable, classification,
-handoff, no-change assertion, and open issues.
-
-Required validation commands:
-
-```powershell
-cmake -S . -B .harness/build -A x64
-cmake --build .harness/build --config Debug
-ctest --test-dir .harness/build -C Debug -R <feature-or-label> --output-on-failure
-ctest --test-dir .harness/build -C Debug --show-only=json-v1
-ctest --test-dir .harness/build -C Debug --output-on-failure
-```
-
-Use configured CMake presets or direct MSBuild commands instead when
-`.harness/config.json` selects them. For Harness Python, Hook, or agent-config
-changes, also run:
-
-```powershell
-uv run --with pytest python -m pytest -v -rs
-```

-## Boundaries

-- Do not change requirements.
-- Do not change formulations.
-- Do not change I/O contracts.
-- Do not change numerical review reports.
-- Do not change reference artifacts.
-- Do not change tolerance policies.
-- Do not change declared reference inputs.
-- Do not modify `docs/<feature-id>/reference-model.md` or its reference-model contracts/evidence,
-  including declared comparison quantities, source identity/component rules, artifact contracts,
-  or approved tolerance, to make comparisons pass.
-- Do not run Abaqus, Nastran, or any reference solver.
-- Do not generate or modify Abaqus reference CSV files.
-- Do not approve release readiness.
-- During planning, do not block on canonical reference naming, README, metadata, provenance, or
-  an unrequested reference portfolio. Require only feature-declared input/CSV files, matching, and tolerance.
-
-## Quality Gate
-
-- Every `must` requirement maps to at least one task and one test.
-- Each test has a clear RED condition, GREEN condition, linked task, and command.
-- CMake/CTest plans remain compatible with MSVC x64 Debug validation.
-- Stop validation is green for the whole discovered C/C++ project; a no-project pass is valid only when no C/C++ files and no build metadata exist.
-- Build/test reports record command, exit code, duration, stdout/stderr tail, and failure classification.
-- Reference comparison rejects missing, extra, duplicate, and nonfinite required rows before tolerance.
-- Warning-only quantities never change the blocking pass/fail result.
-- Reference comparison records per-row decisions and, only where the approved feature contract
-  makes each metric applicable, max absolute error, max relative or component-normalized error,
-  RMS error, and norm error.
-- Compile, link, test, and reference-comparison failures return to Implementation Agent first.
-- Repeated or unclear implementation failures route to Correction Agent through Coordinator Agent.
-- Automatic rework stops when the same normalized failure classification reaches two attempts.
-
-## Handoff
-
-Return the applicable canonical outputs, status, evidence summary, and blockers to Coordinator Agent. Implementation Planning returns `docs/<feature-id>/implementation-plan.md` for one Implementation Agent handoff. A non-final Implementation Step returns only its owned status/summary and applicable evidence. The final Implementation-owned verification Step/gate returns `docs/<feature-id>/implementation-report.md`, `docs/<feature-id>/build-test.md`, and `docs/<feature-id>/reference-comparison.md`; send `pass-for-physics-evaluation` to Physics Evaluation Agent through Coordinator Agent. Correction returns `docs/<feature-id>/corrections.md` and a rerun request to Implementation Agent through Coordinator Agent. Return upstream-contract failures to Coordinator Agent for the owning upstream sub-agent.

-5. Record deferred requirements, unsupported Abaqus keywords, missing required comparison files,
-   unresolved defects, accepted risks, and known limitations.
-6. RELEASE DOCUMENTATION: prepare a release checklist, Known Limitations, and Release Notes Draft.
-7. RELEASE VERDICT: issue `ready-for-release` only when all required evidence is present and passing.
-
-## Output Contract
-
-Produce or revise `docs/<feature-id>/release.md` with:
-
-- Metadata
-- Release Scope
-- Gate Evidence Inventory
-- Acceptance Traceability
-- Validation Evidence
-- Known Limitations
-- Release Notes Draft
-- Release Verdict
-- Handoff Recommendation
-- No-Change Assertion
-- Open Issues
-
-## Boundaries
-
-- Do not implement code.
-- Do not edit source code, tests, CMake files, requirements, formulations, I/O contracts, reference artifacts, or tolerance policies.
-- Do not run Abaqus, Nastran, or any reference solver.
-- Do not generate or modify Abaqus reference CSV files.
-- Do not override failed or missing gates.
-- Do not publish, deploy, package, tag, commit, or externally release anything unless the user explicitly asks.
-
-## Quality Gate
-
-- Do not issue `ready-for-release` without `pass-for-release-agent`, `pass-for-physics-evaluation`, and passing full build/test evidence.
-- Every `must` requirement traces to release scope, acceptance criteria, test or reference evidence, and final disposition.
-- Known limitations and deferred issues are included in the Release Notes Draft.
-- Missing required evidence, contradictory reports, unresolved defects, missing declared comparison
-  files, or unavailable validation commands block release readiness. Canonical naming, README,
-  metadata, provenance, or unrequested portfolio expansion do not.
-
-## Handoff
-
-Return `docs/<feature-id>/release.md`, status, evidence summary, blockers, and a closure recommendation to Coordinator Agent. Return missing implementation/build/comparison evidence, missing physics evidence, upstream gaps, or documentation gaps to Coordinator Agent for the owning sub-agent; do not advance or close the workflow directly.

-# FESA Requirements Baseline
-
-Use this skill to turn a solver feature request into a verifiable baseline that downstream agents can use without guessing.
-
-## Inputs
-
-Read these first:
-
-- `AGENTS.md`
-- `docs/SOLVER_AGENT_DESIGN.md`
-- User feature request, target capability, constraints, and known exclusions
-- Existing `docs/<feature-id>/requirements.md` when revising a feature
-
-## Workflow
-
-1. Assign a stable `feature_id` in kebab case.
-2. Define purpose, included scope, excluded scope, and analysis definition.
-3. Convert requested behavior into `shall` statements with ids like `FESA-REQ-<FEATURE>-###`.
-4. Define verification quantities: displacement, reaction, element force, stress, strain, energy, or residual.
-5. Record Tolerance Policy values or mark them `needs-user-decision`.
-6. Record a minimal Reference Case: exact existing input/required CSV paths, blocking and
-   warning-only quantities, HDF5 projection, source-ID/component matching, and tolerance.
-7. Build a Requirement Verification Matrix that maps requirement, source, verification method, acceptance criteria, tolerance, downstream agents, and status.
-8. Keep unresolved decisions visible as open issues; do not hide gaps behind vague wording.
-
-## Output Contract
-
-Produce or revise `docs/<feature-id>/requirements.md` with:
-
-- Metadata with `feature_id`, status, owner agent, and date
-- Purpose, In Scope, Out Of Scope, and Analysis Definition
-- Input and Output Requirements
-- Verification Quantities
-- Tolerance Policy
-- Reference Case Requirements
-- Requirement Verification Matrix
-- Open Questions and Downstream Handoff
-
-## Boundaries
-
-- Do not implement C++ code.
-- Do not write finite element formulations.
-- Do not design C++ APIs or file ownership.
-- Do not run Abaqus, Nastran, or any reference solver.
-- Do not generate or modify Abaqus reference CSV files.
-- Do not approve release readiness.
-
-## Quality Gate
-
-- Every `must` requirement has a verification method and acceptance criteria.
-- Every numerical solver-output requirement has units, coordinates, and tolerance when applicable.
-- Every reference-comparison requirement names exact required files, compared components,
-  source identity, blocking/warning behavior, and tolerance.
-- Do not require canonical names, README, metadata, provenance, or CSVs for quantities outside
-  the feature acceptance boundary.
-- Words like "accurate", "fast", and "Abaqus-like" are converted into measurable criteria or open questions.
-- Return reference artifact, comparison quantity, source-identity/component, and tolerance gaps for Numerical Review rather than inventing acceptance rules.
-
-## Handoff
-
-Return `docs/<feature-id>/requirements.md`, status, evidence summary, and blockers to Coordinator Agent. Route theory questions to Research Agent and reference acceptance, artifact, identity/component, and tolerance questions to Numerical Review Agent through Coordinator Agent.

-# FESA Research Evidence
-
-Use this skill to collect source-backed evidence for solver features while separating verified facts from inference.
-
-## Inputs
-
-Read these first:
-
-- `AGENTS.md`
-- `docs/SOLVER_AGENT_DESIGN.md`
-- `docs/<feature-id>/requirements.md`
-- User-supplied books, papers, manuals, or benchmark constraints
-
-## Workflow
-
-1. Extract research questions from the requirements and open issues.
-2. Build a Source Inventory with Source Reliability Tier for manuals, standards, books, papers, and benchmark repositories.
-3. Summarize FEM theory needed for the feature without finalizing implementation math.
-4. Identify Candidate Benchmarks, patch tests, analytical checks, MMS/MES candidates, and public examples.
-5. Record Verification Relevance for displacement, reaction, element force, stress, strain, energy, or residual checks.
-6. Record Applicability Limits: element type, material model, deformation assumptions, loading, boundary conditions, and known exclusions.
