Operating Model

Default cadence

• Prefer iterative progress over big bangs.
• Keep diffs small: target ≤ 300 changed lines per PR unless justified.
• Update tests/docs as part of the same change when possible.

Working agreement

• Start with a PLAN for non-trivial tasks.
• Implement the smallest slice that satisfies acceptance criteria.
• Verify via DoD.
• Write a crisp PR summary: what changed, why, and how verified.

Stop conditions (plan first)

Stop and produce a PLAN (do not code yet) if:

• scope is unclear
• more than 3 files will change
• data model changes
• auth/security boundaries
• performance-critical paths
