Por qué importa (del frontmatter del ADR):

Cross-references r08 (catalog federated - load-bearing per CLAUDE.md invariantes globales 'Work → Edition → MediaAsset → SourceBinding') and r60 (Boundary & Authorities Pack - load-bearing per styx.model.yml). r60 is referenced in CLAUDE.md and styx.model.yml. Cited in styx.model.yml extends list via r61.

Por qué pasa gate-3

  • Hard-to-reverse: Immutable catalog semantics per r08 (Work → Edition → MediaAsset → SourceBinding). Reversal to allow placement-driven mutation would break federated catalog invariants, requiring redesign of identity/binding system.
  • Surprising sin contexto: Without ADR context, 'mesh placement' could be interpreted as either (a) policy overlay OR (b) physical mutation. ADR clarifies it's (a), but this interpretation is not inferable from 'placement' alone. r08 catalog federated structure is load-bearing but its immutability invariant is not obvious to engineers working on distributed systems where placement often implies data movement.
  • Trade-off real: Alternatives explicitly considered and rejected: 'Placement Planner as microservicio' - REJECTED per r60 §D1 because 'viola r17 + r28 §3 + duplica role machinery; library consumption per r60'. Cost of policy-only approach = requires separate scheduler/planner library; benefit = preserves microservice boundary per r17 (one container per Authority, no monolithic scheduler). Trade-off is: granularity vs complexity. Also referenced in r60 §D1 mesh aliases mapping: Placement Planner = LIBRARY consumed by F-NODE-FOUNDATION + F-SWARM-CORE.
