Committing to "all schema changes are additive — no renames, no type changes, no column removals" across sprints simplifies rollback, prevents breaking deployed instances, and makes schema review trivial: if a migration only has `CREATE TABLE` and `ADD COLUMN`, it can't break existing data.
A structured document pipeline (user requirements → PDR → plan → expand → implement) turns vague product conversations into executable phase plans. The pipeline's value isn't the documents themselves — it's forcing decisions at the right time and preventing implementation from starting before the de...
When mid-project discoveries require new work that doesn't fit the original phase structure, insert interstitial phases (3.5, 6.5) rather than renumbering downstream phases. This preserves commit history references, plan file anchors, and team communication while accommodating scope changes.
Systematic triage of code review findings produces a traceable requirements document — turning ad hoc observations into prioritized, implementable work.
A repeatable workflow — Design, PDR, Plan, Execute, Commit — with table-driven task tracking and one-commit-per-phase discipline, applied across 18 project phases.
