origin-agnostic-trustworthiness-is-fully-verifiable
OUT derived (depth 10)
The system's complete revision trustworthiness holds identically across all belief origins and is independently verifiable through full maintenance loop observability — trustworthiness is not merely claimed but provable through origin-agnostic audit trails — provided propagation's dependents invariant holds.
Summary
The system can prove it handles all beliefs — whether they came from outside or were generated internally — with equal rigor, and anyone can independently verify this by inspecting the full audit trail of corrections and retractions. This matters because trustworthiness becomes a demonstrable property rather than an assumption, but it currently depends on a propagation invariant that does not hold.
Justifications
SL — Triple convergence of three independent depth-9 achievements; gated because broken propagation dependents would make observability misleading and trustworthiness incomplete
Antecedents (all must be IN):
- revision-achieves-complete-trustworthiness — The revision system simultaneously achieves three independent trustworthiness properties: verifiable soundness (complete two-dimensional provenance/temporal coverage with reliable propagation), end-to-end reliability (across logical and infrastructure layers), and complete auditability (every correction leaves traceable history).
- closed-loop-is-origin-agnostic — The minimality-sustained closed maintenance loop operates identically across all belief origins — external beliefs achieve full integration parity within the same forward-computation and backward-revision cycle as internally-derived beliefs, making the maintenance loop source-agnostic.
- maintenance-loop-is-fully-observable — The minimality-sustained closed maintenance loop has complete observability: every self-correction leaves traceable history (nogoods, retraction records, staleness reports), enabling full audit of how the system maintains itself over time.
Unless (any of these IN defeats this justification):
- propagate-assumes-dependents-exist — Every ID in `node.dependents` is accessed via `self.nodes[dep_id]` without a membership check; a dangling dependent reference will raise `KeyError` — this is intentional (broken invariant = bug)
Dependents
These beliefs depend on this one:
- origin-agnosticism-unifies-trustworthiness-and-grounding — The system's origin-agnostic closed loop simultaneously delivers two independent guarantees from a single architectural source: verifiable trustworthiness across all belief origins and complete invariant grounding for external beliefs — origin indifference is not merely a property but the shared mechanism producing both guarantees.
