A +brief has a stable logical ID and a neutral focus scope: either a canonical workstream or an ad-hoc delegation whose parent scope may identify nested delegation.

It compiles either the canonical top-level +workstreams or explicit ad-hoc/nested delegation scopes, appends only changed +brief versions, and retains explicit retired pointers and immutable history. +Plan apply and rebase commit before their best-effort canonical refresh, so a +bounded compiler diagnostic never rolls back accepted plan intent; the refresh +tool can be retried independently and idempotently. + +Each logical brief retains at most 1,024 immutable versions; exhausting that +history returns terminal `quota_exceeded` with `manual_intervention` recovery. +The newest 256 brief-refresh receipts remain replayable, while older receipts +expire into tombstones and return `request_id_expired`, requiring a new request +ID instead of replaying the original result. + +Brief fingerprints separate owned nodes, relevant nodes, input/output +contracts, relationships, resources, milestones, shared plan content, and +assignment content. Impact and freshness are diagnostic only. They never +change tools, session writability, or implementation authority. + +The optional focused-session prompt overlay is an allowlisted, deterministic, +size-bounded projection. Authored strings are delimited as untrusted data, +delimiter-shaped and Unicode format characters are escaped, sensitive/path-like +values are redacted, and oversized collections are truncated with a diagnostic. +A project session without an overlay receives the common project-agent prompt +byte-for-byte unchanged and keeps the same tool surface. + +Trusted hosts attach an overlay by calling `serializeFocusedSessionContext` +with the exact map, plan, and brief versions, checking its discriminated result, +and passing the branded `projection` through `TrustedSessionCreateOptions` or +`TrustedSessionResumeOptions`. Focused context is rejected outside a trusted +project-agent identity. Ordinary callers cannot construct the branded value, +and authored data must never be appended to a prompt by another serialization +path. diff --git a/packages/harness/src/core/agent-brief-compiler.test.ts b/packages/harness/src/core/agent-brief-compiler.test.ts new file mode 100644 index 00000000..e656c525 --- /dev/null +++ b/packages/harness/src/core/agent-brief-compiler.test.ts @@ -0,0 +1,457 @@ +import { readFileSync } from "node:fs"; +import { describe, expect, it } from "vitest"; + +import type { + AgentMapGraph, + AgentMapVersion, + AgentMapVersionId, + PlanNodeId, +} from "../shared/agent-map.js"; +import { + computeAgentMapVersionRecordDigest, + computeGraphContentDigest, +} from "../shared/agent-map-canonical.js"; +import type { + AgentBriefVersion, + AgentBriefHistoryPointer, + BuildPlanAssignmentIntent, + ProjectBuildPlanContent, + ProjectBuildPlanId, + ProjectBuildPlanVersion, + ProjectBuildPlanVersionId, +} from "../shared/build-plan.js"; +import { parseAgentBriefVersion } from "../shared/build-plan-codec.js"; +import { + computeAgentBriefRecordDigest, + computeAgentBriefSemanticDigest, + computeBuildPlanRecordDigest, + computeBuildPlanSemanticDigest, +} from "./build-plan-canonicalization.js"; +import { + compileCanonicalWorkstreamBriefs, + projectFocusedBriefs, +} from "./agent-brief-compiler.js"; +import { serializeFocusedSessionContext } from "./focused-session-context.js"; +import { + PROJECT_AGENT_PROMPT_APPENDIX, + projectAgentPromptAppendix, +} from "../profiles/project-agent.js"; + +const projectId = "project_018f0000-0000-7000-8000-000000000001"; +const research = "node_018f0000-0000-7000-8000-000000000010" as PlanNodeId; +const publishing = "node_018f0000-0000-7000-8000-000000000011" as PlanNodeId; +const database = "node_018f0000-0000-7000-8000-000000000012" as PlanNodeId; +const researchWork = "work_018f0000-0000-7000-8000-000000000020" as BuildPlanAssignmentIntent["id"]; +const publishingWork = "work_018f0000-0000-7000-8000-000000000021" as BuildPlanAssignmentIntent["id"]; +const actor = { userId: "user", sessionId: "session" }; +const origin = { kind: "request" as const, requestDigest: `sha256:${"1".repeat(64)}`, operationIds: [], touchKeys: [] }; +const golden = JSON.parse(readFileSync(new URL("./fixtures/stock-research-compile.golden.json", import.meta.url), "utf8")); + +const graph = (): AgentMapGraph => ({ + nodes: [ + { id: publishing, kind: "agent", name: "Publisher", purpose: "Publish videos", ownerAgentId: null, contractRefs: ["ResearchReport"] }, + { id: database, kind: "resource", name: "Research DB", purpose: "Store reports", ownerAgentId: null, contractRefs: [] }, + { id: research, kind: "agent", name: "Research", purpose: "Rank stocks", ownerAgentId: null, contractRefs: ["ResearchReport"] }, + ], + relationships: [ + { id: "rel_018f0000-0000-7000-8000-000000000031" as never, fromNodeId: research, toNodeId: database, + kind: "writes", executionMode: "asynchronous", contractRef: "ResearchReport", description: "Stores the report" }, + { id: "rel_018f0000-0000-7000-8000-000000000032" as never, fromNodeId: database, toNodeId: publishing, + kind: "feeds", executionMode: "asynchronous", contractRef: "ResearchReport", description: "Feeds publishing" }, + ], +}); + +function mapVersion(value: AgentMapGraph, version = 1, previous?: AgentMapVersion): AgentMapVersion { + const contentDigest = computeGraphContentDigest(value); + const base = { schemaVersion: 1 as const, projectId, + versionId: `mapv_018f0000-0000-7000-8000-${String(version).padStart(12, "0")}` as AgentMapVersionId, + version, parentVersionId: previous?.versionId ?? null, changeKind: version === 1 ?
