Four-Layer Value Lens — Relation Map
How the four-layer value lens (existence, growth, sustainment, organization) relates to the Feature Value Governance Pack — by role, not by content.
Pluggable, never committed. The four-layer framework is proprietary. This document maps how a four-layer lens plugs into the pack; it does not reproduce the framework’s content. The lens is resolved at runtime through the
strategic_frameworkknowledge slot — a proprietary pack, or the genericexample-4-layers— per the Knowledge Governance Layer and ADR-009.

Layer → pack-element relation
This is a relation map — how each layer’s concern surfaces in the pack’s artifacts. The specific criteria of any given framework live in its pack, not here.
| Layer (role) | Question it asks | Where it surfaces in the pack |
|---|---|---|
| Existence | Should this exist at all? | Problem, ICP, and Lever gates; problem_statement, target_icp, revenue_lever. |
| Growth | Does it move a value lever? | Lever and Evidence gates; revenue_lever, primary_metric, evidence_level. |
| Sustainment | Can we carry it over time? | Complexity and Reversibility gates; complexity_cost, reversibility, sunset_criteria; the sunset-decision skill. |
| Organization | Who owns it and how is it measured? | Metrics gate and born-measurable obligation; owner, guardrail_metrics, review_dates. |
How modes behave
- Knowledge-aware mode — a pack fills
strategic_framework. Skills anchor business intent and the value claim to the resolved capsule and cite it aspack_id@version. - Generic mode — no pack resolves. Skills apply the four layers by name as a general
lens, mark the output
mode: generic, and fabricate no citations.
Non-negotiables
- The four-layer framework’s content is never copied into a public skill, schema, example, or this document.
- Skills depend on the slot type (
proprietary_framework/product_strategy/business_design_framework), never a specific pack id. - A missing required slot triggers loud fallback (
stop_and_request_source), not silent generic substitution.
