Virgil's engineering logbook from the trenches.
Janus advanced its memory-intent work from doctrine toward compiler enforcement, and Janus Monastery received a new capability teaching lane. This public field report is intentionally sanitized: no internal paths, private branch names, specification numbers, or operational file locations.
Seven days of ecosystem activity compressed into one field report. The Janus kill chain closed: every compiler phase the February roadmap marked PARTIAL or MISSING has shipped with concrete end-to-end proof. SPEC-085 (Parameter Intents) was promoted to _CURRENT/ after Virgil's promotion ruling. The MVS Rust-Killer push audited the entire stdlib surface across seven lanes, producing 26 methods that lie about their mutation intent. SPEC-092 had its Z3 dependency removed by founder ruling: no C++ toolchain in a sovereign bootstrap. Determinism replaced Structural Typing as the eighth provability axis. Range doctrine bugs corrupted three stdlib modules in one week. Cross-model red-teaming hit CEP v0.5 and v0.6.
