 | 8.7 `[D:7.6,8.3]` | **IN PROGRESS.** Pure Go ticket policy binds the expected App ID and verified identity, rejects expiry/replay/wrong app/malformed tickets, and consumes each ticket once | `server/domain/auth.go` covers single-use and binding invariants; real `AuthenticateUserTicket` backend adapter, bans, publisher secret store and Steam verification remain |
 | 8.8 `[D:8.7]` | **IN PROGRESS.** Pure Go session policy issues opaque short-lived tokens, stores only digests, authenticates by verified player identity and supports revocation | `server/domain/auth.go` covers wrong-token/expiry/revocation behavior; distributed revocation, account/IP limits, request limits and production session persistence remain |
 | 8.9 `[D:8.4,8.7]` | **IN PROGRESS.** Pure Go join policy binds SteamID/player/match/server/team/slot/protocol/expiry, rejects duplicate roster slots, permits same-identity reclaim through backend loss and fences prior server-owned generations | `server/domain/reconnect.go` covers SteamID/server/slot binding, expiry, repeated reclaim, grace boundary and old-generation fencing; signed token issuance/verification, persistent leases, Godot `hello` transport and production integration remain |
-| 8.10 `[D:8.5,8.31]` | Authenticate results with pod-bound projected identity or one-match attested credential; validate issuer/audience/expiry, namespace/SA, pod UID, GameServer UID and allocator match binding | Another pod sharing a workload class cannot submit for the allocation; identical duplicates are idempotent; conflicting results are inert and alerting across all trusted clusters |
+| 8.10 `[D:8.5,8.31]` | **IN PROGRESS.** Dependency-free workload credential policy validates an adapter-verified signature, issuer/audience/time bounds, namespace/service account, pod UID, GameServer UID, allocation ID, match ID and server ID before result submission | `server/domain/workload.go` and adversarial tests reject every binding mutation, missing/unverified signature and time boundary; `server/testkit/pipeline_test.go` carries allocation identity through the offline result path; projected-token/JWT adapter, trusted-cluster verification and live duplicate/conflict alerting remain |
 | 8.11 `[D:8.1]` | **DONE.** Write the threat model: forged clients/replay/queues/results, floods/bots, pod/insider compromise, gameplay and API DDoS, SDR signing-key theft, dependencies and denial-of-wallet | [`docs/THREAT-MODEL.md`](docs/THREAT-MODEL.md) records prevention, detection/response, owner and residual risk for every threat; it separates offline CA/online signer, client/game-server/PostgreSQL/Redis trust boundaries and recovery behavior |
 | 8.12 `[D:8.11]` | Harden workloads and edge: restricted containers, least RBAC, private DB/Redis, default-deny networks, backups/secrets, volumetric DDoS/WAF/origin shielding, WebSocket limits and overload shedding | Policy/network tests enforce declared flows; edge load test preserves result ingress/live matches while rejecting new work; no credential appears in Git/images/args/telemetry |
 | 8.13 `[D:8.12]` | Pin images by digest; generate SBOMs, scan dependencies/images, sign artifacts, verify signatures at admission and document a critical-fix SLA | CI blocks a vulnerable/disallowed or unsigned release artifact and records the exact provenance deployed |
