go-postgres-missing-table-in-migration-chain
Done. The solution is written to ~/SOLUTION.md (also read back above for a final check).
Situation: The workspace contained only /workspace/problem.json (no source repo), so I reconstructed a faithful minimal migration chain from the problem description and verified the fix against a live Postgres 18.4 server (same semantics as the required postgres:17-alpine for CHECKs, triggers, RLS, uuid, jsonb).
What I verified empirically:
1. Reproduced the bug — applying the chain without the new migration, the store's INSERT fails with ERROR: relation "procurement_runs" does not exist (SQLSTATE 42P01), exactly the 500.
2. Fixed chain applies cleanly in glob order with ON_ERROR_STOP=1 (000001 → 000016 → 000100).
3. Full endpoint flow at SQL level: project insert (201) → requirements ready → procurement insert with status='running', current_phase='' (202) → update to completed/100 with the updated_at trigger firing (t).
4. Edge cases: current_phase='' accepted; progress_pct=101 correctly rejected by the CHECK (23514 path now works because the table exists); RLS enabled + procurement_runs_all policy present.
The fix in the document:
- internal/store/postgres/migrations/000016_procurement_runs.up.sql — mirrors the store SQL exactly: id uuid PK, project_id uuid NOT NULL REFERENCES projects(id), the three CHECKs (incl. current_phase=''), phases jsonb, created_at/updated_at, BEFORE UPDATE trigger on update_updated_at_column() (defined in 000001), and the RLS policy created inside this migration since the RLS glob runs after 000099.
- Go wiring: SetConsensusClient setter on the service struct plus nil-safe graceful degradation inside runProcurement.
- Verification section with the exact psql commands and a required end-to-end API checklist (201 → ready → 202 → completed/100), plus rollout notes for fresh vs. existing databases and a warning not to touch the decoy migrations directory.
