What's Changed

v0.3.0 — Typed IR compiler-architecture milestone.

This release is about core compiler abstraction rather than feature count: a
static Typed IR now sits between the AST and the Polars/Burn backends,
eliminating the old double-interpretation (the runtime no longer re-parses the
source to interpret the raw AST).

Highlights

  • Typed IR (xazz-core::ir): ColType / Schema / TypedExpr /
    DataOp / MLOp / SideOp / Step(order-preserving tags) / PipelineNode.
  • Double-parse removed: the type checker produces diagnostics and the IR
    in a single walk (analyze_program / compile_ir); the runtime consumes that
    IR once. The old execute_var_decl-style interpreter was deleted (-606 lines).
  • IR optimizer (xazz-compiler::opt): constant folding, consecutive
    Select merge, predicate pushdown — enabled via xazz-exec --opt, proven
    semantics-preserving by Polars execution-equivalence tests.
  • Direct-buffer tensor bridge: contiguous Float64/Float32 columns are read
    straight from Arrow buffers (cont_slice), removing per-column intermediate
    copies; the remaining copy boundaries are documented in the memory model.
  • DP composition accounting: PrivacyBudget now tracks (ε, δ) jointly
    (Laplace pure ε-DP, Gaussian consumes δ too); XAZZ_DP_DELTA_BUDGET added.
  • Execution timeout hardening in xazz-runner (XAZZ_EXEC_TIMEOUT_SECS).
    Confirmed: subprocess isolation is not an OS sandbox.
  • God-runtime split: xazz-exec decomposed into lower / dl / dp /
    chart + a thin runtime orchestrator (1433 → 720 lines).
  • Version management unified: single workspace version (0.3.0), xazz-server
    adopted the workspace version/edition; internal path-dep version pins removed.
  • Prior Unreleased work (guardrails, DL engine, checker, audit log, Visual IDE,
    --opt, etc.) is included in this release.

Included Binaries

Binary Role
xazz CLI entry point
xazz-runner IPC bridge (process isolation + timeout)
xazz-exec Typed-IR consuming runtime (Polars + Burn)
