Under the hood

Useful1 Signal1

Elsewhere

Bash safety tables are built at startup instead of on first use, with identical rules.

What

The command argument tables, the plain-English verb descriptions, the read/write classification and the per-command danger checks are now built at load time instead of on first use. The rules, flag sets and patterns are identical.

Details

An allow-list for the aki command present in 2.1.247 does not appear in this part of the build.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
