🎯 §1.2 production-validated whole-library: tomli full public API
translated end-to-end via real LLM (codex gpt-5.5), 5/5 canonical
entrypoints PASS, 12/12 functions translated, 9.16-13.94× faster than
CPython tomllib, 99.71% fuzz pass rate, pip-tools downstream 5/5
byte-identical.

§1.1 Language & Runtime real (not demo): real fizzbuzz algorithm
(while + if/elif/else + modulo), real recursive fib (Constant::FnRef
Call lowering), shared lower_condition root primitive (LC 263 closed),
inferred_locals fixed-point root primitive (closed Conway-toy +
Float→I8).

35 ADRs accepted, 14 findings published, 178 cumulative commits, 768
workspace tests passing, cross-arch validated macOS arm64 + Linux
x86_64.

Phase E milestones (M0..M14 + M11.1..M11.3): all merged. Phase F
roadmap (ADR-0038): F.1 6-month tier delivered for 0.1.0-beta.

Multi-agent topology methodology: documented in finding
`multi-agent-cobrust-topology` for external adoption. ~~6~~ 7 recurring
failure modes + SOPs.

This release: build-in-public, no marketing pretense. Mojo, PyO3,
Cython are prior art and complementary; Cobrust is "AI Python
accelerator with auto-translation + safety, transparent PyO3 wrapper".
