This adds a new (Private Preview) OpenAI C2C source doc. Found two concrete issues by comparing the doc's JSON schema table against its own reference examples:

schemaRef JSON schema table uses smart/curly quotes instead of straight quotes, producing invalid JSON.

The row reads:

| schemaRef | JSON Object | `{"type": "OpenAI"}` | Yes | Define the specific schema type. |

I checked the raw bytes and confirmed those are typographic quotes (U+201C/U+201D — " "), not ASCII ". If a customer copy-pastes this directly into a JSON config, it's a syntax error. static/files/c2c/openai/example.json gets this right ("schemaRef": {"type": "OpenAI"} with straight quotes) — only the table row has the bad characters, likely from pasting out of a doc editor that auto-converts quotes.

pollingInterval is inconsistent between its own type/default, and is missing from both reference examples despite being marked Required.

The Configuration Object table says:

| pollingInterval | Integer | Yes | `5 minutes` | Time interval (in minutes)... |

• Type is Integer but the default value 5 minutes is a string with a unit, not a valid integer.
• It's marked Required: Yes, yet static/files/c2c/openai/example.json and example.tf both omit pollingInterval entirely from their config objects. A customer copying either reference example literally would be missing a required field.

Minor completeness gap (not blocking): the Source configuration steps link Project IDs and API Key IDs to #vendor-configuration for guidance, but that section only explains how to obtain the Admin API Key — it doesn't explain where to find Project IDs or API Key IDs.

Everything else — the cid-redirects.json entry, the Private Preview badge/noindex pattern, and the sidebar omission (consistent with this repo's convention of not listing Private Preview C2C sources in sidebars.ts) — looks correct.

The doc is well-structured overall, but the JSON schema table has two issues that would trip up anyone following it literally — see comment above for details. Please fix the smart quotes in the schemaRef row and reconcile pollingInterval's type/default/required status with the reference examples before merging.

@JV0812 Thanks for the catch — both issues are fixed in 719185e:

• schemaRef smart quotes: replaced with straight quotes ({"type": "OpenAI"}) so the table row is valid JSON.
• pollingInterval: changed to Required: No with default 5 (matching its Integer type), and added "pollingInterval": 5 to both example.json and example.tf so the reference examples are complete.

Left the Project IDs/API Key IDs #vendor-configuration link gap as-is per your note that it's non-blocking — happy to follow up in a separate pass if you'd like it addressed now.

[JV0812]

Confirmed both fixes directly against the PR head content: schemaRef now uses straight ASCII quotes, and pollingInterval is now Integer/Required: No/default 5, matching both reference examples (which now include the field). Verified with a clean local build. Approving.
