v2

v2 is a cursor rule for Cursor from Chia-Network/cadt. It costs 46 tokens per session (998 once invoked), scanned A, original, Apache-2.0.

A set of development rules for a version 2 API, its database, migrations, tests, and related code.

In plain words
What is it for?
Use it while implementing or reviewing version 2 API endpoints, database tables, migrations, and tests.
Why use it?
It prevents inconsistent names, keys, timestamps, request validation, and database relationships when changing the version 2 system.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

v2 scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

V2 Development Rules

Reference Files

  • Database schema: v2-schema.dat (DBML format)
  • Development plan: v2-api-implementation-editable.plan.md -- if "STOP" appears, halt and wait for user feedback

Naming Conventions

  • Database columns: snake_case
  • API fields: camelCase, mapping directly to DB columns (e.g., orgUid -> org_uid, metaKey -> meta_key)

Paths

  • CHIA_ROOT: ~/.chia/mainnet/
  • CADT config: ~/.chia/mainnet/cadt/config.yaml
  • V2 database: ~/.chia/mainnet/cadt/v2/

Primary Keys (CRITICAL)

  • Data tables: VARCHAR(36) storing UUID v4, generated via uuid.v4() in application code
  • System tables: INTEGER AUTO_INCREMENT
  • NEVER use INTEGER PRIMARY KEY AUTOINCREMENT for data tables

Foreign Keys

  • Application-level validation only (no DB constraints)
  • Check both main table AND staging table for references

Timestamps

  • Managed by Sequelize (created_at, updated_at)
  • Reject if provided in POST/PUT requests

API Request Patterns (CRITICAL)

  • PUT requests: MUST include ALL fields, not just changed ones
  • POST requests: include all required fields
  • Same validation schema for CREATE and UPDATE
  • Most list endpoints require page and limit: Entity data endpoints (program, methodology, issuance, label, stakeholder, stakeholder-projects, unit-label, project-methodology, estimation, location, rating, co-benefit, validation, verification, staging, audit, and all aef-* tables) enforce paginationSchema — omitting page/limit returns 400 ("page is required","limit is required"). Always include .query({ page: 1, limit: <N> }).
  • project and unit require page/limit UNLESS xls=true is also passed (XLS export mode skips pagination).
  • Endpoints that do NOT require pagination: organizations, governance, offer, filestore, and health/* endpoints return all results without page/limit.

Staging and On-Chain Data Validation (CRITICAL)

  • Every record staged to StagingV2 — regardless of entry path (REST API, XLSX import, CSV batch import, split/transfer flows, or any future path) — must pass the same validation as the REST API: Joi schema, FK existence, and NOT NULL completeness. Use validateStagedRecord in src/utils/v2-staging-validation.js; do not hand-roll per-path checks.
  • Rationale: staged records become on-chain DataLayer values verbatim, and every subscriber re-ingests them into models with allowNull: false columns. A single incomplete record permanently halts sync for all subscribers of the registry.
  • StagingV2.assertChangeListNotNullCompleteness is a last-line-of-defense commit gate (NOT NULL only). It must never be the only validation on a write path.
  • Any new write path must call the shared validator and add a parity test proving the same invalid payload is rejected identically via the API path.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

v2 is a cursor rule published in the GitHub repository Chia-Network/cadt (41 stars, last pushed 2d ago), licensed Apache-2.0. It adds 46 tokens to every session and 998 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
