fix(quota): fail closed when quota verification errors (#331) (#523)
* fix(quota): fail closed when quota verification errors (#331)

Quota enforcement fell open on unexpected errors: the outer `except` in
`authorize_workflow_run_start` returned `has_quota=True`, so a degraded
database or a config-resolution bug let a billable run start unverified.
Billing and abuse protection are control-plane functions, so this is the
wrong default under exactly the degraded conditions that matter.

- Fail closed by default: the outer handler now returns
  `has_quota=False` / `quota_check_failed`, reusing the existing message.
- Add `QUOTA_FAIL_MODE=closed|open` (default `closed`) so OSS self-hosters
  can explicitly opt back into availability; the open path logs loudly.
- Narrow the try-scope so `get_user_by_id` / `get_workflow_run` DB read
  failures surface as their specific `user_not_found` /
  `workflow_run_not_found` codes instead of the generic handler.
- Tests cover the config-resolution and DB-read failure paths (denied,
  not `has_quota=True`) and the `QUOTA_FAIL_MODE=open` escape hatch.

Fixes #331

* fix(quota): route DB read failures through the fail-mode policy gate

Review (greptile) flagged that the narrowed get_user_by_id / get_workflow_run
catches returned user_not_found / workflow_run_not_found before the outer
QUOTA_FAIL_MODE handler ran, so QUOTA_FAIL_MODE=open never applied to a DB
failure -- the exact "degraded database" case the escape hatch documents.

Revert the two narrowed catches so DB read exceptions fall through to the
single outer policy gate: closed -> quota_check_failed, open -> allow. The
None checks still return the specific not_found codes for genuinely missing
rows; an exception is a "cannot verify" condition, not a definitive absence.

Add a regression test asserting QUOTA_FAIL_MODE=open allows a run when a DB
read throws, and update the two DB-error tests to expect quota_check_failed.

* docs(quota): scope the fail-mode comment to credit-verification failures (#331)

Review (cubic) flagged the outer-handler comment as overclaiming: it said the
handler is the single gate for "all cannot-verify errors", but the earlier
workflow-load and org-membership catches always deny with workflow_not_found
regardless of QUOTA_FAIL_MODE. That distinction is intentional (those are
authorization/existence gates, not credit verification), so scope the comment
accordingly. Comment-only, no behavior change.

* fix(quota): fail open only when MPS is unreachable

🚀 Get Started

Download and setup Dograh on your Local Machine

Note

We collect anonymous usage data to improve the product. You can opt out by setting ENABLE_TELEMETRY=false before running the startup script.

Note

If you wish to run the platform on a remote server instead, checkout our Documentation

curl -o docker-compose.yaml https://raw.githubusercontent.com/dograh-hq/dograh/main/docker-compose.yaml && curl -o start_docker.sh https://raw.githubusercontent.com/dograh-hq/dograh/main/scripts/start_docker.sh && chmod +x start_docker.sh && ./start_docker.sh

Prefer an AI agent to set it up for you? If you use Claude Code or Codex, install the official Dograh setup skill and let your agent handle installation, configuration, and troubleshooting — it detects your OS, picks the right deploy path, runs Dograh's own setup scripts, and verifies the result.

# In Claude Code
/plugin marketplace add dograh-hq/dograh-plugins
/plugin install dograh@dograh

Then start a new session and ask it to "set up Dograh" (or run /dograh-setup). Codex is supported too — see the plugin repo.

Note

First startup may take 2-3 minutes to download all images. Once running, open http://localhost:3010 to create your first AI voice assistant! For common issues and solutions, see 🔧 Troubleshooting.

🎙️ Your First Voice Bot

  1. Open http://localhost:3010 in your browser.
  2. Pick Inbound or Outbound, name your bot (e.g. Lead Qualification), and describe the use case in 510 words (e.g. Screen insurance form submissions for purchase intent).
  3. Click Web Call — you're talking to your bot.

🔑 No API keys needed. Dograh ships with auto-generated keys and its own LLM / TTS / STT stack. Connect your own keys for LLM, TTS, STT, or Telephony (e.g. Twilio, Vonage, Telnyx) anytime.
