Education Migration Tickets

This directory turns GOAL.md into executable, blocker-aware vertical slices.

Workflow

Work only tickets whose blockers are complete.
Start each implementation ticket in a fresh context after reading GOAL.md, the ticket, relevant decisions, and current Git status.
Preserve the dirty working tree. Implementation is serial unless an isolated worktree and integration plan are explicit.
Apply TDD at the ticket's declared seams.
Use flyway-postgresql for every schema, index, constraint, seed, baseline, backfill, or Flyway configuration change.
Close with focused tests, git diff --check, and mvn -pl yudao-server -am -DskipTests clean compile.
Report exact commands and results. Never report PostgreSQL migration success without an actual successful PostgreSQL run.

Status vocabulary

done: implemented and verified to the ticket's current acceptance criteria.
in-progress: currently being implemented.
ready: all blockers complete and no unresolved decision prevents work.
blocked: depends on another ticket or product decision.
decision: produces a recorded decision rather than production behavior.

Recommended execution order

EDU-010 — Continue with the provider-consistent question publication lifecycle; V4070 graph integrity is delivered.
Continue through EDU-011/EDU-012 as their blockers clear.

Phase 0 completion caveat

Phase 0 artifacts exist, but several architecture and product decisions remain open. EDU-000 is considered complete as an inventory deliverable, not as resolution of every decision it discovered.
