+# {{ .project_name }} — Instructions for Claude
+
+## Shared Engineering Rules
+Read `bible/` — shared rules for all projects (CSV, logging, DB, tables, background tasks, code style).
+Start with `bible/kit/patterns/` for specific contracts.
+
+## Project Architecture
+Read `bible-local/` — project-specific architecture.
+Every architectural decision specific to this project must be recorded in `bible-local/`.
+
+---
+
+## Quick Reference (full contracts in `bible/kit/patterns/`)
+
+### Go Code Style (`go-code-style/contract.md`)
+- Handler → Service → Repository. No SQL in handlers, no HTTP writes in services.
+- Errors: `fmt.Errorf("context: %w", err)`. Never discard with `_`.
+- `gofmt` before every commit.
+- Thresholds and status logic on the server — UI only reflects what server returns.
+
+### Logging (`go-logging/contract.md`)
+- `slog`, stdout/stderr only. Never `console.log` as substitute for server logging.
+- Always log: startup, task start/finish/error, export row counts, ingest results, any 500.
+
+### Database (`go-database/contract.md`)
+- **CRITICAL**: never run SQL on the same tx while iterating a cursor. Two-phase: read all → close → write.
+- Soft delete via `is_active = false`.
+- Fail-fast DB ping before starting HTTP server.
+- No N+1: use JOINs or batch `WHERE id IN (...)`.
+- GORM: `gorm:"-"` = fully ignored; `gorm:"-:migration"` = skip migration only.
+
+### REST API (`go-api/contract.md`)
+- Plural nouns: `/api/assets`, `/api/components`.
+- Never `200 OK` for errors — use `422` for validation, `404`, `500`.
+- Error body: `{"error": "message", "fields": {"field": "reason"}}`.
+- List response always includes `total_count`, `page`, `per_page`, `total_pages`.
+- `/health` and `/api/db-status` required in every app.
+
+### Background Tasks (`go-background-tasks/contract.md`)
+- Slow ops (>300ms): POST → `{task_id}` → client polls `/api/tasks/:id`.
+- No SSE. Polling only. Return `202 Accepted`.
+
+### Tables, Filtering, Pagination (`table-management/contract.md`)
+- Server-side only. Filter state in URL params. Filter resets to page 1.
+- Display: "51–100 из 342".
+
+### Modals (`modal-workflows/contract.md`)
+- States: open → submitting → success | error.
+- Destructive actions require confirmation modal naming the target.
+- Never close on error. Use `422` for validation errors in htmx flows.
+
+### CSV Export (`import-export/contract.md`)
+- BOM: `\xEF\xBB\xBF`. Delimiter: `;`. Decimal: `,` (`1 234,56`). Dates: `DD.MM.YYYY`.
+- Stream via callback — never load all rows into memory.
+- Always call `w.Flush()` after the loop.
