- docs/v2-build-and-runtime.md: new — runtime split rationale (Node host,
Bun container), lockfile topology, supply-chain trade-offs, image build
surface, two session-wake paths, CI shape, key invariants. Indexed from
CLAUDE.md v2 Docs Index.
- CLAUDE.md: Container Runtime (Bun) section with trigger/action gotchas
a contributor editing the container must know (named-param prefix rule,
bun:test vs vitest, bun.lock regeneration, no minimumReleaseAge for the
Bun tree, no tsc build step, DELETE pragma invariant). CJK font support
section for Claude sessions outside of /setup to proactively offer when
they detect CJK signals. Development section updated with Bun commands.
- .claude/skills/setup/SKILL.md: step 3b — auto-enable CJK fonts without
asking if the user is already writing in CJK; otherwise ask only on clear
signals (CJK timezone from step 2a). 3c renumbered from old 3b.
