+### 4.2 Impact Decisions
+
+Before verification, record one bounded current-state evidence basis covering the requested surface, material upstream dependencies or producers, downstream consumers, validation/test surfaces, and relevant dirty work.
+
+```yaml
+impact_decisions:
+  basis:
+    requested_surface: [path-or-symbol]
+    current_state_sources: [evidence-ref]
+    dirty_work: clean | related | unrelated
+    stopping_reason: string
+  relations:
+    - id: IMP-001
+      relation: string
+      direction: upstream | downstream | validation | cross-cutting
+      materiality: string
+      disposition: accepted | excluded | blocking
+      evidence: [evidence-ref]
+      projects_to: [REQ-001, AC-001]
+      reason: string
+  none_relevant:
+    value: false
+    searched_boundary: string
+    reason: string
+```
+
+Treat a relation as material only when its disposition could change a requirement, constraint, acceptance criterion, user-observable or contractual outcome, architectural boundary, measurable quality target, validation target, or declared boundary. Every material relation has exactly one `accepted | excluded | blocking` disposition. `projects_to` is required for accepted relations and must name stable requirements, constraints, interfaces, acceptance criteria, or validation targets. Excluded relations require evidence and a concise reason; "the user did not mention it" is not sufficient. Blocking relations create blocking Open Questions and keep the quality gate blocked.
+
+Use `none_relevant` only after a bounded scan finds no material relation and records its searched boundary, reason, and `stopping_reason`. Stop when further exploration could change none of those surfaces and record the reason. Escalate to targeted Git history, prior work artifacts, execution evidence, or durable knowledge only for contradictory current-state evidence, unresolved ownership, material regression/causality, or a suspected governing legacy decision; do not require full-history archaeology or broad knowledge retrieval by default.

 Only approved keep-summarizing owners write durable knowledge. Final orchestration review owns approved persistence delegation and may invoke that owner, then validate returned paths or an evidence-backed no-write result; executors and orchestration itself must not write knowledge directly.
 
+Specification authoring materializes `impact_decisions` from bounded current-state evidence about the requested surface, upstream/downstream relations, validation surfaces, and relevant dirty work. A relation is material only when its disposition could change a requirement, constraint, acceptance criterion, user-observable or contractual outcome, architectural boundary, measurable quality target, validation target, or declared boundary. Each material relation is `accepted | excluded | blocking`: accepted relations use `projects_to` for stable specification IDs, excluded relations require evidence, and blocking relations prevent verification. Stop when further exploration could change none of those surfaces and record the reason; a greenfield result may use `none_relevant` only with the searched boundary, reason, and `stopping_reason`. Targeted Git history, prior work artifacts, execution evidence, or durable knowledge is an escalation for contradiction, unresolved ownership, material regression/causality, or suspected governing legacy decisions—not mandatory full-history archaeology or broad knowledge retrieval. This impact-decision view is compared by semantic convergence; repository traversal remains owned by specification authoring.

 ## Lightweight development lane
 
 Use `dev-create-task-plan` for bounded mechanical work with stable decisions. After preflight and source grounding it invokes one bounded `ks-what-is-helpful` gateway, carries accepted authority or evidence-backed `none relevant`, writes one disposable plan under `.work-bundle/runtime/dev-plans/`, and creates no orchestration artifact tree. Its lightweight completion owner records an evidence-backed no-write result for `none`; for `update`, `supersede`, or `reclassify`, it invokes the approved keep-summarizing lifecycle and validates return evidence before completion. Escalate to full orchestration for unresolved architecture/API/data/workflow decisions, wide impact, multiple repositories, migration/deployment sequencing, unresolved durable-knowledge decisions, or parallel contract/barrier needs.

 The body must contain `Quality gate: verified|blocked`. Planning may proceed only with `verified`, a converged semantic loop, resolved blocking questions, stable IDs, and explicit Knowledge Base Update disposition. Set that disposition to `required` when the work establishes durable reusable decisions; specification authors do not write durable knowledge directly.
