chore(version): bump Claude Code min-version floor to v2.1.172#593
Merged
Conversation
v2.1.172 fixed wildcard-domain WebFetch permission rules (WebFetch(domain:*.gov.uk)) that never matched subdomains on earlier clients — exactly the shape ArcKit's security-hooks guide recommends for confining research-agent traffic in OFFICIAL-SENSITIVE deployments, so the floor makes that guidance actually hold. v2.1.172 also includes the Claude Fable 5 runtime (GA in v2.1.170); ArcKit defaults to the latest model tier. The v2.1.156 Opus 4.8 thinking-block fix and the Fable 5 GA note are carried forward as per-feature lines in the version-check warning. Updated every floor reference: - version-check.mjs MIN_CLAUDE_CODE_VERSION + two warning bullets (Fable 5 needs v2.1.170, WebFetch wildcard fix needs v2.1.172) + header comment - CLAUDE.md floor mention; README install + "Why" explainer + requirements - enterprise-scale.md requiredMinimumVersion example - hooks/README.md nudge-gate note (floor above the 2.1.163 gate; the soft-warning path still guards sub-floor clients) - repo .claude/settings.json minimumVersion (dogfood) + create-test-repo template minimumVersion Left untouched: historical CHANGELOG entries and the generic version-parse fixtures in test_hook_utils.mjs (not floor references).

What
Bumps ArcKit's Claude Code minimum-version floor v2.1.156 → v2.1.172.
Primary driver: v2.1.172 fixed wildcard-domain
WebFetchpermission rules (WebFetch(domain:*.gov.uk)) that never matched subdomains on earlier clients — exactly the shape ArcKit'sdocs/guides/security-hooks.mdrecommends for confining research-agent traffic in OFFICIAL-SENSITIVE deployments. The floor makes that shipped guidance actually hold (previously a deny-then-wildcard-allow policy would have blocked all WebFetch traffic).Secondary: v2.1.172 also carries the Claude Fable 5 runtime (GA in v2.1.170); ArcKit defaults to the latest model tier. The v2.1.156 Opus 4.8 thinking-block fix and the Fable 5 GA note are preserved as per-feature lines in the version-check warning.
