flowguard-field-lifecycle-mesh

name	flowguard-field-lifecycle-mesh
description	Use when a change adds, removes, renames, migrates, replaces, externalizes, preserves, or audits fields, schema keys, config flags, prompt fields, payload columns, persisted attributes, defaults, aliases, or fallbacks.

FlowGuard Field Lifecycle Mesh

Purpose

Account every discovered leaf field, project behavior-bearing fields upward, and close old-field disposition before broad confidence.

Entrypoint Scope

Route id: field_lifecycle_mesh; role: public_owner; native owner: field_lifecycle_mesh. This standalone FlowGuard satellite skill owns field boundaries and projections, not downstream behavior proof.

Local Material Routing

Read references/field_lifecycle_mesh_protocol.md for FieldLifecyclePlan, grouped leaf rows, projections, replacement policy, and handoffs.

Entrypoint Acceptance Map

Accept a bounded field inventory; create leaf rows and behavior projections; block missing fields or unknown old-field disposition; hand canonical malformed cases, owners, obligations, and repair evidence to their routes.

Use When

• Use for schema/payload/config/prompt/persisted/UI/runtime fields, migrations, aliases, defaults, fallbacks, or field-rooted model misses.

Do Not Use When

• Do not put every field in the high-level model, treat inventory as behavior proof, or replace alignment/testing; return missing behavior models to model-first-function-flow.

Required Workflow

1. Define the field boundary, parent groups, and every discovered FieldLifecycleRow.
2. Add FieldProjection rows only for behavior-bearing fields and route invalid/old cases to ContractExhaustionMesh.
3. Close replacement disposition and send owners, readers/writers, projections, cases, and gaps downstream.

Hard Gates

• Model-purpose gate: before build/change, freeze this instance's task-specific failure(s) and boundary; then bind candidate plus native good/bad-per-failure/oracle/current evidence. Reusable types are not fixed-purpose; no mode/fallback; SkillGuard only supervises FlowGuard-declared checks.
• Verify the real FlowGuard check engine and AGENTS.md managed record; never create a fake mini-framework.
• Default replacement requires delete, block, migrate, delegate, repair, explicit preserve, or scoped reason; unknown disposition blocks full confidence.
• Behavior claims still require current obligations, owner code contracts, tests, freshness, and template harvest closure where the model deepens.

Output Requirements

• Return evidence, failures, blockers, skipped_checks, residual_risk, claim_boundary, and typed_next_actions, plus leaf rows, projections, owners, and dispositions.

SkillGuard Maintenance

• Edit .skillguard/contract-source.json, then regenerate derived contracts; SkillGuard validates field accounting and cannot fabricate behavior or compatibility evidence.
