logmind: log decisions as you work

Applies when the project has .logmind/config.yml or an AGENTS.md mentioning logmind. Log a decision before writing non-trivial code.

When to log

• An architectural or design choice
• A choice between alternatives
• Significant new code (> 20 lines or a new module)
• A non-obvious change to existing functionality
• Adding or removing a dependency
• A security or performance decision

When in doubt, log it — an entry is cheap; recovering the context later is not. But don't log every tiny edit: the 20-line rule is a guideline; use judgement.
