Files were modified even being under 'Plan Mode'

[peyrona]

Description

Plan mode was active (not Build) I asked for suggestions, but OpenCode allow files modifications and modified several files. This is something VERY serious.

OpenCode version

1.0.150

Steps to reproduce

I do not think there is a procedure that can reproduce it.

In the log of actions I see what appears to be Explore sub-agent running which has its own set of permissions. Explore sub-agent's intention seems to be read-only, on the other hand it uses the default set of agent permissions which include

bash: {
  "*": "allow",
},

if I'm reading the relevant code part correctly.
