From 0495fedcff14ea00e663057e543f23d470a256ff Mon Sep 17 00:00:00 2001 From: "Mars.P" Date: Wed, 7 Oct 2026 03:22:14 +0800 Subject: [PATCH] Keep model-authored acceptance from carrying a setup command A supervisor reply could author acceptance.setupCommand and acceptance.timeoutSeconds even though the decision schema never offers them. The server's schema check does not read additionalProperties, a schema-less fallback request carries no schema at all, and the bind maps any member SupervisorAcceptanceSpec declares. The projector froze both into the ledger, and every supervisor grading lane handed them to the grader, which ran the setup argv in the grading workspace (with host network under bubblewrap) and read a timeout of 0 as no wall clock at all. ModelAuthoredAcceptanceConverter now sits on the four acceptance slots a supervisor decision carries (plan subtask, plan phase, stop, amend replacement) and drops both knobs on read and on write. Because it is on the slot, it also covers ledger rows written before this change, which the rehydrate re-reads on every turn. Operator specs (node config, AgentTask.Acceptance) keep both. The grader now bounds every step's window itself (setup, check and the oracle restore's git commands), because the supervisor lanes never validate the contract first: a non-positive value grades at the 300 s default and anything longer is capped at 3600 s. EvaluatorVersion moves to v8 for that change. An operator contract is validated, so it is no longer rewritten silently: ValidateAuthored refuses a timeoutSeconds outside 1..3600 with a message naming the ceiling. agent.code fails at staging, and the executor's and local verifier's contract check fails closed as SpecIncomplete before anything runs. Only lanes that never validate still rely on the grader's bound. The stop gate's reader is now internal and pinned directly, so the stored-row test exercises the production reader instead of a copy. GradeDirectoryAsync's doc no longer claims that grading the agent's live directory is equivalent to grading a clone. --- .../Agents/AgentAcceptanceContract.cs | 9 + .../Supervisor/ISupervisorAcceptanceGrader.cs | 11 +- .../Supervisor/SupervisorAcceptanceGrader.cs | 17 +- .../Services/Supervisor/SupervisorLane.cs | 11 + .../SupervisorTurnService.Rehydrate.cs | 4 +- .../ModelAuthoredAcceptanceConverter.cs | 31 ++ .../Agents/SupervisorAcceptanceSpec.cs | 10 +- .../Agents/SupervisorDecisionPayloads.cs | 9 +- .../Agents/SupervisorPlanPhase.cs | 3 +- .../LocalAcceptanceVerifierFlowTests.cs | 21 +- ...SupervisorModelAcceptanceSetupFlowTests.cs | 276 ++++++++++++++++++ .../Agents/SupervisorAcceptanceGraderTests.cs | 54 +++- .../SupervisorAcceptanceVerdictTests.cs | 8 + .../SupervisorModelAcceptanceBoundaryTests.cs | 184 ++++++++++++ .../Workflows/AgentCodeNodeTests.cs | 23 ++ 15 files changed, 655 insertions(+), 16 deletions(-) create mode 100644 backend/src/CodeSpace.Messages/Agents/ModelAuthoredAcceptanceConverter.cs create mode 100644 backend/tests/CodeSpace.IntegrationTests/Workflows/SupervisorModelAcceptanceSetupFlowTests.cs create mode 100644 backend/tests/CodeSpace.UnitTests/Agents/SupervisorModelAcceptanceBoundaryTests.cs diff --git a/backend/src/CodeSpace.Core/Services/Agents/AgentAcceptanceContract.cs b/backend/src/CodeSpace.Core/Services/Agents/AgentAcceptanceContract.cs index d03478a2b..46c2f8bba 100644 --- a/backend/src/CodeSpace.Core/Services/Agents/AgentAcceptanceContract.cs +++ b/backend/src/CodeSpace.Core/Services/Agents/AgentAcceptanceContract.cs @@ -1,4 +1,5 @@ using System.Text.Json; +using CodeSpace.Core.Services.Supervisor; using CodeSpace.Messages.Agents; using CodeSpace.Messages.Agents.Benchmark; using CodeSpace.Messages.Enums; @@ -215,12 +216,20 @@ _ when detail.StartsWith($"{ModelCheckGateLabel}: ", StringComparison.Ordinal) = /// rubric, a schema check with no schema) would invert the gate's fail-closed philosophy.
