Executing Plans (Symfony)

Use when

• An approved implementation plan exists and must be carried out.
• The work spans several steps that must each land green.
• Resuming a plan after an interruption or a blocker.

Default workflow

1. Read the whole plan, confirm the baseline tests pass, and work on a branch.
2. For each step, write the test, watch it fail, implement, watch it pass, then refactor.
3. Commit after each completed step, with a message that names it.
4. Run the quality gates (style, static analysis, full suite) at the end of each phase.
5. Track each step's status in the plan, and stop to report when reality contradicts it.

Guardrails

• Never skip watching the test fail: a test that never failed proves nothing.
• One step per commit; do not batch steps.
• Do not change the plan silently: report the deviation and the reason.
• On a blocker (failing migration, autowiring error), fix the cause, not the test.
