// recall.hook.example.json - paste-in template for ~/.claude/settings.json
//
// OPT-IN / DISABLED BY DEFAULT. Bounded vault recall: on every prompt, inject
// a small brief (max 4 notes, ~900 chars) of the most relevant vault notes -
// or nothing at all when confidence is low (abstention). Read-only; it never
// writes to the vault. It does nothing until BOTH env vars are set AND the
// UserPromptSubmit hook is registered:
//      "env": {
//        "OBSIDIAN_VAULT_PATH": "/path/to/your/vault",
//        "OBSIDIAN_RECALL_ENABLED": "1"
//      }
//
// Every inject/abstain decision is logged to <vault>/.claude-runs/
// recall-YYYY-MM-DD.jsonl so you can audit what got recalled and why.
//
// To DISABLE again: set OBSIDIAN_RECALL_ENABLED to "0" (or remove it). The
// hard gate in the script makes clearing the flag enough, even if the hook
// stays registered.
