cortex can now validate locally-unrecognised bearer keys against the
helexa-upstream authority and reserve/settle their budget there — mesh
accounts work for real inference. The EntitlementProvider trait is the
seam, so cortex's enforcement (auth.rs, metering.rs) is otherwise
unchanged.
- entitlements_upstream.rs: UpstreamEntitlementProvider over reqwest →
B2's /authz/v1 (resolve/reserve/settle/release/snapshot), presenting the
operator client bearer. Maps the wire contract back to the trait: granted
→ Reservation, rejected → BudgetError, 401 → InvalidKey. Fail-closed —
unreachable resolve → AuthError::Unavailable (503, never 401);
unreachable reserve → retryable BudgetError::RateLimited (refuse, never
serve un-authorized). settle/release are best-effort (the upstream
sweeper reaps a lost one).
- entitlements_chain.rs: ChainedEntitlementProvider tries local first
(operator + infra keys, no network), falls through to upstream for
unknown keys, and dispatches reserve/settle/release/snapshot to whichever
backend resolved each account (local treats unknown principals as
uncapped, so it can't be the blind default).
- cortex-core: AuthError::Unavailable{retry_after_secs}; [upstream] config
(enabled/url/bearer/timeout). auth.rs maps Unavailable → 503 +
Retry-After distinctly from InvalidKey → 401, regardless of require_auth.
- state.rs wires the chain when [upstream].enabled, else stays purely local.
Tests (upstream_chain.rs, 4): local key resolves without touching upstream;
unknown key falls through to a mock upstream; unknown-everywhere → 401
InvalidKey; upstream-unreachable → Unavailable (503-mapped), with local keys
still resolving. Existing gateway suites updated for the new config field.
