defeat-reversal-is-automatic-with-guided-recovery
IN derived (depth 4)
All outlist-based defeat mechanisms (challenge, kill-switch, supersession) not only reverse automatically through BFS propagation cascades — recovering all transitively dependent nodes — but also provide surgical recovery guidance through restoration hints that target cascade victims with surviving premises, enabling both automatic and manual recovery paths.
Summary
When something that was blocking other conclusions gets withdrawn, the system does two things at once: it automatically restores every downstream conclusion that was knocked out, cascading recovery through the entire dependency chain, and it also flags specific recovery opportunities where a knocked-out conclusion still has other valid support lines available. This means users get both hands-free recovery and actionable guidance for cases that need attention, so no valid conclusion stays lost after a defeat is undone.
Justifications
SL — Automatic reversal handles the common case (retract the defeater, everything recovers), while guided recovery handles the complex case (multi-premise justifications where only some premises survive) — together they provide complete recovery coverage.
Antecedents (all must be IN):
- defeat-reversal-propagates-automatically — All outlist-based defeat mechanisms (challenge, kill-switch, supersession) not only reverse in principle but propagate recovery automatically through safe terminating BFS — when a defeating node is retracted, the outlist entry becomes satisfied, and propagation cascades truth-value restoration to all affected nodes without manual re-assertion
- defeat-reversal-with-guided-recovery — All defeat mechanisms (challenge, kill-switch, supersession) are reversible through outlist semantics, and the system provides surgical restoration hints for cascade victims with viable recovery paths — enabling guided recovery from retraction cascades where multi-premise justifications have surviving premises.
Dependents
These beliefs depend on this one:
- all-revision-mechanisms-are-traceable-and-recoverable — Every belief revision mechanism — contradiction resolution (dependency-directed backtracking with consistent nogood IDs) and defeat reversal (automatic outlist-driven recovery with surgical restoration hints) — provides complete traceability and guided recovery across all revision paths.
- belief-modification-is-bidirectionally-complete-and-traceable — Belief modification is complete in both directions: contradictions that create truth changes are resolved through traceable dependency-directed backtracking with consistent nogood IDs, AND defeats that suppress truth values reverse automatically through BFS propagation with surgical restoration hints — no truth change is either irresolvable or irreversible without full traceability.
- defeat-reversal-is-topology-complete-with-guided-recovery — Automatic defeat reversal with surgical recovery guidance propagates through topology-complete inconsistency-safe cascades — recovery reaches all transitively affected nodes including outlist-connected ones, handles dangling references gracefully, and provides restoration hints targeting only cascade victims with surviving premises.
- negative-semantics-are-complete-reversible-and-recoverable — The system's negative semantics form a complete belief modification lifecycle: complete semantics cover all negation forms (structural absence and explicit outlist defeat), all defeat mechanisms reverse automatically through BFS propagation cascades, and surgical restoration hints target only cascade victims with surviving premises — every belief retraction can be undone with guided recovery.
