-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project
-
-Axolotl (`ax`) is a CLI-native issue tracker built in Go, using a local SQLite file (`.ax.db`) as its database. It's designed for use by individuals and AI agents, with JSON output support for machine integration.
-
-## Commands
-
-```bash
-go build -o ax .        # Build the binary
-go test ./...           # Run all tests (e2e_test.go covers most functionality)
-go test -run TestName . # Run a single test by name
-```
-
-## Architecture
-
-The codebase has three distinct layers:
-
-### 1. `cmd/` — CLI layer (Cobra)
-Parses flags into typed input structs and calls the service layer. `root.go` handles alias expansion (including `$me`, `$@`, `$1`-`$N` variable substitution) and wires up the `NodeService`. Also contains `output.go` for colored terminal output and JSON serialization.
-
-### 2. `service/` — Business logic
-`NodeService` is the central interface (`service/node_service.go`). The implementation (`node_service_impl.go`) enforces:
-- Permission model via `getPermContext()` — BFS from the user's own node following permission rels
-- Blocker validation (can't close an issue with open blockers)
-- `@mention` extraction → automatic edge creation
-- Single-value relation enforcement (`assignee`, `in_namespace`)
-- Auto-creation of referenced user/namespace nodes
-
-### 3. `store/` — Persistence and configuration
-`GraphStore` interface wraps SQLite with graph primitives: nodes, tags, and typed directed edges. Schema is 3 tables (`nodes`, `tags`, `rels`). All multi-step ops use `store.Transaction()`. Also contains `Config` for user settings, aliases, and session management.
-
-## Core Data Model
-
-**Node**: a graph node with a 5-char ID, title, content, `Tags []string`, and `Relations map[string][]string`.
-
-**Property tags** use the `_key::value` pattern: `_type::issue|note|user|namespace`, `_status::open|done`, `_prio::high|medium|low`.
-
-**Relation types** (`models/rel_type.go`): `blocks`, `subtask`, `related`, `assignee` (single-value), `in_namespace` (single-value), `created`, `mentions`, `can_read`, `can_create_rel`, `can_write`, `has_ownership`.
-
-**Permission model**: Four inclusive levels (1–4). Transitive via BFS from user's self-owned node. `can_read`=1, `can_create_rel`=2, `can_write`=3, `has_ownership`=4. Creator auto-gets `has_ownership` on every new node. Users self-own. Deleting a node cascades to all nodes it owns. User/namespace nodes are globally readable.
-
-## Config
-
-The CLI searches upward from CWD for an `.ax` directory (like git), falling back to `~/.config/ax/` for config and `~/.local/share/ax/` for data. The `AX_USER` env var overrides the configured username. The database file `ax.db` is similarly discovered by walking upward.
