+## Gitea Actions Workflow Structure (2026-07-24)
+
+### Workflow Architecture Refactoring
+
+**2026-07-24 refactoring**: Single-job ci.yml (30+ steps, ~40min runtime) → **9-job parallel pipeline** (~15-20min runtime).
+
+### CI Pipeline Jobs (ci.yml)
+
+| Job | Dependencies | Purpose | Parallelizable |
+|-----|--------------|---------|---|
+| **core** | — | CRITICAL: .NET tests, API trading gate, KIS creds, DB migrations | ✗ (blocks others) |
+| **wbs-audit** | core | WBS validation, platform migration, coverage audits | ✓ |
+| **dotnet-contracts** | core | .NET parity, provenance, scheduler, normalization contracts | ✓ |
+| **ui-storage** | — | Admin UI, storage backend, integration tests | ✓ |
+| **database-schema** | — | DB pipeline, PostgreSQL schema, history contracts | ✓ |
+| **calibration-pipeline** | core | Calibration priority, change ledger, qualitative sell strategy | ✓ |
+| **operational-reporting** | calibration | Decision packet, operational report, performance metrics | ✗ (depends on calibration) |
+| **security-validation** | — | Secrets contract, workflow validation | ✓ |
+| **workflow-lint** | — | CI workflow structure, secrets contract | ✓ |
+| **notify-results** | ALL | PR notification with job status summary | — |
+
+**Dependency Graph**:
+```
+core ─┬─> wbs-audit ─────────────────────┐
+      ├─> dotnet-contracts ─────────────┤
+      └─> calibration-pipeline ────────┤
+              └─> operational-reporting ─┤
+                                         └─> notify-results
+ui-storage ────────────────────────────────┘
+database-schema ──────────────────────────┘
+security-validation ───────────────────────┘
+workflow-lint ─────────────────────────────┘
+```
+
+### Other Workflow Files
+
+| File | Trigger | Purpose | Status |
+|------|---------|---------|--------|
+| **kis_data_collection.yml** | cron (00:30 KST M-F) + dispatch | Validate KIS credentials & PostgreSQL pipeline | ✓ 2026-07-24 |
+| **qualitative_sell_strategy.yml** | cron (00:15 KST M-F) + push + dispatch | Validate sell strategy pipeline & store | ✓ 2026-07-24 |
+| **workflow_lint.yml** (was ci_lint.yml) | push (.gitea/workflows/) + dispatch | Lint all workflow files, validate job dependencies, secrets contract | ✓ 2026-07-24 |
+| **snapshot_admin.yml** | push (snapshot_admin_*) + dispatch | Validate snapshot admin workflow & UI (2 jobs) | ✓ 2026-07-24 |
+| **prepare-release.yml** | workflow_run (ci.yml success) + dispatch | Build, tag, create Gitea Release with artifact + checksums | — |
+| **deploy-prod.yml** | dispatch | Deploy release, run health checks, report status (3 jobs) | — |
+
+### Performance Improvements (2026-07-24)
+
+**ci.yml refactoring results**:
+- **Before**: 1 job, 30+ sequential steps, ~40min runtime
+- **After**: 9 jobs, 7 in parallel, ~15-20min total runtime
+- **Speedup**: ~2-2.5x faster CI feedback (core branch blocks only downstream, others parallel)
+- **Fault isolation**: Single validation failure no longer blocks unrelated checks
+
+**Key changes**:
+1. **Setup consolidation**: Database migrations, Python, .NET setup in `core` job only
+2. **Parallel validation groups**: 7 jobs run independently from core (ui-storage, database-schema, security-validation, workflow-lint, etc.)
+3. **Dependency clarity**: `needs:` explicitly defines blocking relationships
+4. **Error reporting**: `notify-results` summarizes all 9 job statuses in PR comment
+
+### Workflow Maintenance Checklist
+
+When modifying workflows (.gitea/workflows/*.yml):
+
+1. ✅ Update `workflow_lint.yml` if adding new triggers or job dependencies
+2. ✅ Test locally with `python3 tools/validate_gitea_ci_workflow_lint_v1.py`
+3. ✅ Verify all `needs:` references point to existing jobs
+4. ✅ Document new jobs in this section above
+5. ✅ Validate YAML syntax: `python3 -m yaml < .gitea/workflows/new.yml`
+6. ✅ Ensure no hardcoded secrets in workflow files (env vars only)
+
+### Troubleshooting Workflows
+
+**Symptom**: CI job timeout
+- **Check**: Does your job need PostgreSQL? Only `core` provides it; others must be independent.
+- **Fix**: Add `services: postgres:` block or restructure to parallel-safe job.
+
+**Symptom**: Cascading failure (multiple jobs fail)
+- **Check**: Does your job have missing dependencies? Review `needs:` and dependency graph above.
+- **Fix**: Add explicit `needs: [job_name]` if job depends on another's output.
+
+**Symptom**: "job not found" error in notify-results
+- **Check**: Job name typo in `notify-results.needs` list.
+- **Fix**: Match job name exactly (case-sensitive).

+## Workflow Trigger Schedule (2026-07-24)
+
+| Time (KST) | Workflow | Trigger | Purpose |
+|-----------|----------|---------|---------|
+| 00:15 | qualitative_sell_strategy.yml | cron (M-F) | Validate sell strategy before daily operations |
+| 00:30 | kis_data_collection.yml | cron (M-F) | Validate KIS API & DB pipeline before data collection |
+| Push | ci.yml | on:push (main) | Validate code on every push to main |
+| PR | ci.yml | on:pull_request | Gate PR merges with full validation suite |
+| Manual | prepare-release.yml | workflow_dispatch | Create release tag & artifact |
+| Manual | deploy-prod.yml | workflow_dispatch | Deploy release to production |
+
+**Dependencies**: 
+- Release creation (prepare-release.yml) is gated by ci.yml success (workflow_run trigger)
+- Deployment (deploy-prod.yml) is manual — only after release artifact exists
