Document the authentication compatibility window.
setAuthHeader sends ServiceAccount, but hyperfleet-api/pkg/auth/jwt_handler.go accepts only Bearer and returns HTTP 401 for other schemes. Until the API accepts both schemes, prefix this entry with BREAKING CHANGE: and state that the API must be upgraded before Sentinel. If the rollout accepts both schemes, document that compatibility window instead; a simultaneous upgrade is not required. This changelog warning does not fix the wire-contract mismatch.

Keep the chart authentication contract compatible with hyperfleet-api.
When authentication is enabled, Sentinel sends ServiceAccount <token>, but hyperfleet-api accepts only Bearer and returns HTTP 401 for this request. Keep Sentinel and the chart on Bearer, or release API support for ServiceAccount with this change.

Keep the client compatible with the current API.
setAuthHeader now sends ServiceAccount <token>, but hyperfleet-api/pkg/auth/jwt_handler.go:119-163 rejects every scheme except Bearer. Every authenticated request from this client will receive HTTP 401 until the API middleware is updated and deployed. The adapter and shared architecture contract also still use Bearer. Coordinate the server and contract rollout, or retain Bearer here.

One thing worth addressing before this merges, the scheme needs to be configurable. Rest of the rename is fine.

Heads up, hard-coding ServiceAccount here breaks every deployment where the API validates the token itself. jwt_handler.go in the API accepts Bearer only and 401s anything else, so JWT_AUTH_ENABLED=true without the gateway stops working on this image, and so does anything pointed at an operator-managed API, which has in-app JWT on by default and no gateway yet. It also closes the door on 1484.
Prob better to make it a config field on HyperFleetAPIAuthConfig, default Bearer, and let infra set ServiceAccount when the gateway is on:
scheme := c.authScheme
if scheme == "" {
scheme = "Bearer"
}
req.Header.Set("Authorization", scheme+" "+tok)Keeps the released chart backwards compatible and means the client doesn't need to know which auth boundary it's talking to.

Following on from the client comment, this wants a scheme: Bearer value next to audience, wired through to the config the same way tokenPath is. Infra then overrides it per environment.

If the scheme stays hard-coded this is a BREAKING CHANGE for anyone on in-app JWT, so it should be marked as one. With the knob it's an additive entry and this line is fine as is.
