backend-agnostic-operational-assurance

OUT derived (depth 8)

The system's comprehensive operational assurance — spanning temporal self-correction, end-to-end reliability, and external control — holds identically across both storage backends with equivalent safety guarantees, provided PgApi achieves full API parity with the SQLite path.

Summary

This claim says that all the system's reliability guarantees — catching its own errors over time, staying within resource limits, and being controllable from the outside — would work equally well on either SQLite or PostgreSQL, as long as the PostgreSQL implementation fully matches the SQLite API. It is currently retracted because one or both of its supporting claims (that safety is truly backend-independent, and that assurance covers all operational dimensions without gaps) are not held to be true.

Justifications

SL — Full operational assurance across backends requires complete PgApi API coverage

Antecedents (all must be IN):

  • safety-is-enforced-across-all-layers-and-backends — Safety is enforced uniformly across both the architectural dimension (clean layer boundaries with atomic isolated mutations) and the storage dimension (equivalent guarantees through backend-appropriate mechanisms in SQLite and PostgreSQL) — no safety property depends on a specific backend or architectural layer.
  • system-assurance-spans-correction-reliability-and-control — The system's operational assurance spans three independent dimensions: temporal completeness of self-correction (creation-time contradiction resolution and maintenance-time staleness detection), resource sustainability (bounded token budgets preventing exhaustion), and external controllability (bidirectional interface bounds with defensive ingestion) — no assurance gap exists along any axis.

Unless (any of these IN defeats this justification):

  • pgapi-partial-api-coverage — PgApi implements core operations (add/retract/assert/search/nogood/explain) but defers simulation, dialectics, namespace support, import/export, and maintenance operations to future work
