## Error

```text
requested permissions … haven't granted
```

## Symptom
A server spawns `claude -p ... --permission-mode acceptEdits --settings policy.json` to handle user requests. Requests that attach files (images, spreadsheets saved under `/srv/uploads/...`) or need `/tmp/x.diff` fail: the run reports that Claude requested permissions to read the file but they haven't been granted, and stops.

## Cause
`acceptEdits` auto-approves edits inside the working directory only. Reading paths outside cwd still needs an interactive approval, and in `-p` (print/headless) mode nobody can answer the prompt, so it is treated as denied.

## Fix
Run headless agents with permission bypass and express the policy through `deny` rules and hooks instead of prompts:
```bash
claude -p "$ASK" --permission-mode bypassPermissions --settings /srv/svc/settings.json
```
(Run it as a dedicated non-root user.) Alternatively keep `acceptEdits` and add explicit allow rules such as `Read(//srv/uploads/**)` and `Glob(//srv/uploads/**)` to the settings file.

## Verify
After the change, an uploaded `.xlsx` was read with openpyxl and answered within ~8 s, and image attachments were read. `deny` rules still held under bypass: a `Read` of `.env.local` was refused.

## Notes
Bypass mode makes prefix-based Bash deny rules your only shell guard — and they are easy to evade (see the separate entry about `Bash(git push:*)`). Add a PreToolUse hook.
