Goal

Reduce review latency and rework by shipping smaller, independent slices.

Default Slice Budgets

• Target <= 400 changed lines per slice when practical.
• Target <= 10 changed files per slice when practical.
• Target 1-4 commits per slice.
• Keep each slice behaviorally coherent and independently verifiable.

Slicing Order

1. Extract prerequisites first.
2. Land mechanical refactors next.
3. Land behavior changes after prerequisites are merged.
4. Land UI/docs/polish last.

Slice Packet Template

For each slice, define:

• Goal
• Owned files
• Out of scope
• Risk level (low/medium/high)
• Verification command(s) with expected pass condition
• Rollback plan

Hard Rules

• Avoid mixing refactor and behavior changes in one slice unless unavoidable.
• Avoid touching unrelated subsystems in one slice.
• Avoid cross-slice hidden dependencies.
• If a slice depends on unmerged work, state it explicitly.

Verification Discipline

• Run narrow checks first for touched behavior.
• Run project gate checks before handoff.
• Record exact commands and outcomes for each slice.

Final Handoff Format

• Slice list with order and purpose
• Per-slice owned files
• Per-slice verification evidence
• Residual risk and follow-up slices
