v0.0.6-alpha.3 was published on 7 November 2026. It adds four pure numerical built-ins for finite vectors, along with internal scalar compiler correctness work. Scarp remains an experimental interpreter-backed language; this is not a stable release.
Deterministic Top-K ranking
topk(scores, count) returns the original zero-based indices of the highest scores, greatest first, as an immutable integer collection. topk_values(scores, count) returns their original numerical values in the same order. Equal scores prefer the earlier input index, and asking for zero results is valid. Input scores must be finite; selection is subject to explicit work and allocation quotas.
bind scores = [1.0, 5.0, 5.0, -2.0, 3.0];
print(topk(scores, 3));
print(topk_values(scores, 3));[integer: 1, 2, 4]

Temperature-controlled probabilities
softmax_temp(scores, temperature) computes a probability vector. logsoftmax_temp(scores, temperature) computes its log probabilities. Temperature must be a positive finite float. Stable maximum-shifting and compensated normalization reduce avoidable overflow; unrepresentable log probabilities are diagnosed rather than published as infinite values. These are deterministic transformations, not random sampling.
print(softmax_temp([2.0, 2.0], 0.5));
print(logsoftmax_temp([5.0], 2.0));[0.5, 0.5]

Compiler correctness, not general native compilation
The experimental scalar C11 backend now uses compiler-owned typed expression and statement IR internally, with validation of branches, storage initialization and type expectations. Test-only differential execution compares outcomes against the interpreter. This does not add a public scarp compile CLI or a general native compiler.
Compatibility and limits
These functions extend the existing numerical built-ins without new source syntax or CLI commands. Earlier read-only symbol inspection, vector rms and optional Rust embedding caches remain. Rust embedding consumers exhaustively matching the numeric built-in enum may need changes. Scarp still has no LSP, general tensor engine, GPU backend, model-training framework, top-p sampling, package registry or stable ABI.
