Compose the live relational-neighborhood geometry OPERATORS into five reasoning
modes as pure, read-only C (engram_reason.{h,c}); each is proven with closed-form
constructed tests before it ships, not declared.
- ANALOGY (Procrustes R + residual translation, apply to C, rank candidates)
- INDUCTION (combine-pooled rule geometry + point-to-manifold membership)
- ABDUCTION (best-explaining structure by point-to-manifold fit)
- CAUSAL (centroid-cosine correlation vs directed influence: temporal
precedence + association surviving confounder control via subtract;
emits a correlation-vs-causation flag)
- PLANNING (geo-distance edges + Dijkstra → discrete geodesic path)
A shared point-to-manifold fit primitive underlies induction membership and
abduction ranking. engram/test/run_reason_tests.sh: 33/33 checks on both PERF
and ASan/UBSan passes; macOS leaks 0/0.
ANALOGY is surfaced as an el builtin (engram_reason_analogy_json) via the same
pass-through the §5 operators use — demonstrated callable from compiled El with a
container-capped fold (no self-host fold). The other four are C-layer only: their
set/point/timestamp inputs do not map to the flat-CSV el ABI without touching
codegen (deferred). engram_reason.c must join the server link line beside
engram_geometry.c at cutover. See docs/runbooks/2026-08-13-reasoning-operators-*.
