Implements LEARN-3 with frozen paired fixtures, crash-safe journals, target isolation probes, and measured learning-transfer verdicts.
Supersedes local checkpoints 3022df5, 715c831, 9fb5d0f, and fe635f1; those attestations were invalidated and never used for real model runs.
The skill has outgrown its name — it reviews designs and runs repo audits,
not only code. cs-review is the canonical entry; cs-code-review ships as
the one thin forwarding alias (the explicit exception to the no-shim rule,
kept for the carried-over v1 habit). References in cs / cs-feat / cs-epic /
cs-issue / cs-refactor, the Codex agent config, both contract-test skill
sets (V2_SKILLS + SHIM_SKILLS), and all public docs / CHANGELOG / ADR-004
updated. Also refreshed the leftover v1 openai.yaml wording. 96 passed.
