[bug]: opencode-zen — Console retired budgets/org (now 409); budgets moved to /api/policies/current-budgets #320

Versions

• opencode-quota 5.0.2 (npm latest and next; no newer version exists)
• OpenCode v2, Linux (Fedora Silverblue)

Symptom

The opencode-zen provider shows no monthly limit and logs an error, even though a workspace budget is configured in the Console:

opencode_zen:
- console_auth_state: configured
- balance_usd: USD 27.75806885
- monthly_limit_usd: (none)
- monthly_usage_usd: USD 11.4977624
- budget_source: credit_limit
- live_fetch_error: OpenCode Console budgets/org error 409
- live_probe: partial

Other providers (e.g. github-copilot) track correctly, so this is provider-specific, not a general failure.

Cause

On 2026-10-10 the OpenCode Console moved budgets into Controls → Policies (changelog: "Budgets have a new home — Controls → Policies replaces the old workspace, member and service account budget settings, including default limits and shared budgets.").

The Console's own UI no longer calls budgets/org; it calls:

GET /console/api/policies/current-budgets  -> 200
GET /console/api/policies                  -> 200

The old route is retired:

GET /console/api/budgets/org               -> 409 {"_tag":"Conflict"}

This is not auth and not a missing budget:

• The same OAuth token + same x-org-id returns 200 on billing/status, usage/cost-by-day, policies and policies/current-budgets.
• Correct org id → 409; a wrong org id → 403. So the 409 is the route itself, not permissions.
• A workspace budget was configured during the probe.
• fetchConsoleRoute (opencode-zen.js) tolerates 403/empty (the [bug]: budgets/org returns null without an org budget → permanent "Could not parse" error for opencode-zen #297 fix) but not 409, so the 409 surfaces and monthlyLimit falls back to creditLimit (which is null), leaving no limit shown.

New shape

GET /console/api/policies/current-budgets:

[{"policyID":"policy_legacy_budget_88030",
  "ruleID":"rule_legacy_budget_88030",
  "limitDollars":30,
  "scope":"combined",
  "per":"set",
  "spentDollars":2.73543333,
  "modelCount":0}]

Differences from budgets/org:

• it is an array of policies, not a single object;
• limitDollars / spentDollars are in dollars, not micro-cents;
• scope is combined (one shared pool) or each (per member); per is set;
• period ("month") and the reset live in GET /api/policies — current-budgets has no resetsAt;
• it returns the workspace (combined) and member (each) policies, but not service-account policies.

Suggested fix

• Call policies/current-budgets instead of budgets/org.
• Parse limitDollars / spentDollars as dollars; prefer the scope:"combined" entry for a single "monthly limit" figure.
• Stopgap: treat 409 like 403/empty (no budget → fall back to the credit limit) so the error stops surfacing while the new endpoint is wired in.
