Data plane and secret hygiene

Additive hitl.* schema on the shared Postgres (hitl.tickets); kg.* andgtins.* are untouched by this service.

The connection string lives ONLY as a Container App secret. It is nevercommitted, never written into deploy files, never echoed, and never logged.Application code reads process.env.DATABASE_URL and nothing else — seeserver.js and console.js. Deploy docs reference the DSN as a placeholderonly. Verified by a full-history credential scan: zero literal secret values.

Licensing

No license file is committed. GSC MCP server code is under a hybridMIT + Commercial Enterprise arrangement; the counsel-drafted terms are pending.Until they land, absence of a LICENSE file is deliberate — not an oversight.
