Public trust baseline
Completed for the current public surface with verified claims, visible stability labels, and bounded replacement messaging.
Optimization plan
Make the language reliable before making it loud.
The full roadmap is also tracked in GitHub under docs/OPTIMIZATION_PLAN.md.
Conformance and correctness harness
Completed for the current stable-core surface with parser, typecheck, diagnostics, and stdlib gates.
Native backend reliability
Completed for the current Windows/Linux x64 surface with native smoke, byte-reproducibility gates, and fail-closed unsupported targets.
Standard library hardening
Completed for the current stable-candidate stdlib slice with ownership docs, failure rules, and math/string/vector/arena edge gates.
Developer experience
Completed for the current first-user workflow: actionable diagnostics, fmt idempotence, lint rule IDs, examples, LSP source, snippets, run, and native build gates.
Ecosystem and package trust
Completed for the current first-party SDK package set with tezz command coverage, SemVer pins, lock/registry parity, package checksums, generated package docs, and CI gates.
Python bridge, C ABI, benchmarks, releases
C ABI, release security, and the starter benchmark proof are complete for the current public surface.
Actor runtime and OTP-like apps
Started with local actors, mailbox matching, supervisor restarts, hot version tags, node metadata, and OTP-style app helpers. Distributed scheduling and hot replacement remain gated.
