"""Tests for the claude-native "don't ask again" pure helpers.

The persistent allow-rule affordance for non-edit native tools relies
on two synchronous helpers in the sessions route:

- ``_allow_remember_eligible`` — server-side gate (stamp + verdict)
  deciding which tool/mode combinations may offer/honor the rule.
- ``_claude_native_remember_host`` — derives the WebFetch domain host
  the rule scopes to, with a tool-wide fallback.

Both are exercised end-to-end in the integration suite; these unit
tests pin the gating and URL-parsing edge cases directly.
