POST /config/update stored keys the config file owns and answered 200
while the file silently kept winning. Run the config-owned check for
general_settings, litellm_settings, and router_settings before the first
database read, the way /config/field/update already does, so a refused
request stores nothing.
The config reload re-loaded the merged settings as yaml settings, which
turned every saved router setting read-only after one tick. Read the
saved router settings row instead so database-owned values stay writable.
The integration harness seeds num_retries through /config/update instead
of the config file, which is what the effective-settings and observed
routing tests need to keep exercising a database-owned value.
Adds integration contracts for MCP lifecycle, protocol errors and OAuth
configuration, A2A wire versions, the OpenAI consumer path, persisted
toolsets, callback delivery, guardrail effects, configured prices, the
filtered spend ledger, and a CircleCI-owned browser flow for project
detachment, with the ASGI, browser-state, client and MCP helpers they use.
