architecture-sustains-gapless-lifecycle
IN derived (depth 4)
Architectural safety (clean layer boundaries with atomic isolated mutations) sustains gapless lifecycle management (staleness detection plus propagation lifecycle awareness) — beliefs are correctly managed at every point in their lifecycle, backed by structural guarantees that lifecycle operations execute atomically and without cross-layer leakage.
Summary
The system's architectural properties — clean separation between layers and atomic mutations — are what make it possible to reliably manage beliefs through every stage of their life, from creation through staleness detection to retraction. Without those structural guarantees, lifecycle operations like propagation or staleness checks could partially execute or corrupt state across boundaries, leaving beliefs in inconsistent states.
Justifications
SL — architectural enforcement ensures lifecycle operations execute correctly and without gaps
Antecedents (all must be IN):
- architecture-enforces-structural-and-operational-safety — Architectural safety is enforced along two independent dimensions: structurally, the central network dependency is contained within clean three-layer boundaries preventing cross-layer corruption; operationally, every mutation path is atomic and isolated preventing within-layer partial state — neither dimension alone is sufficient, but together they eliminate both classes of corruption.
- lifecycle-management-is-gapless — The system manages belief lifecycle without gaps across all operation types: staleness checking detects all forms of source drift, propagation respects node lifecycle states, and both read and write paths enforce consistent lifecycle semantics — no operation ignores or corrupts lifecycle state.
Unless (any of these IN defeats this justification):
- missing-source-file-is-silent — If a node's source file no longer exists on disk, `check_stale` silently skips it; callers cannot distinguish "file deleted" from "file never tracked."
- hash-truncation-is-16-hex — Source hashes are SHA-256 truncated to the first 16 hex characters (64 bits), reducing collision resistance to ~32 bits for birthday attacks compared to the full 256-bit hash.
Dependents
These beliefs depend on this one:
- lifecycle-is-deterministic-and-architecturally-grounded — Gapless lifecycle management is doubly reinforced: deterministic reasoning ensures predictable state trajectories with full monitoring, while architectural safety provides the structural foundation through clean layer boundaries and atomic mutations.
