From 1fd19da7a7104bdcac094cdbbb2d70f337c9477e Mon Sep 17 00:00:00 2001 From: Jacques Wainwright Date: Mon, 3 Aug 2026 07:38:32 +0200 Subject: [PATCH 01/13] feat(agents): durable managed-agent runtime Turn managed Buzz agents into persistent colleagues with a single identity, serialized inbox, resumable channel sessions, durable assignment ownership, detached authenticated jobs that outlive an ACP turn and a Desktop restart, signed relay progress (kinds 43001-43006), Desktop reattachment, and persistent assignment state. Adds: durable inbox + session store; privileged job supervisor with identity verification, crash reconciliation, cancel/stop process-tree cleanup; loopback runtime-control server with generation-scoped capabilities; relay job protocol validation; managed no-shell capability profile; schema-v2 Desktop adoption; agent-to-agent collaboration across restarts; legacy schema-v1 pair-lock safety. Baseline: block/buzz ac4fa13b (2026-08-01). Feature-flagged rollout per the persistent managed-agent runtime plan (Phases 0-6).

Mark completed only after verified delivery and include delivery evidence; a terminal assignment cannot be reopened. +- Use messages_send, messages_get, messages_thread, and messages_search for channel-scoped coworker collaboration. Use agents_list and agents_status to discover shared managed coworkers and their current availability/work status. Reply anchors and mentions must refer to current channel events and members. Do not expose credentials, control capabilities, private blocker details, or local paths in messages. +- Start durable governed work with jobs_start. Omit target_agent (or use this agent's pubkey) for local work: the privileged runtime fixes the driver, validates the workspace, persists the request, and owns the job lifetime. Use a different shared managed agent's pubkey to publish a signed public job request; this never connects to, spawns, or controls the coworker's runtime locally. Supply the source channel/event, Legacy Harness arguments, approved cwd, and a concise summary. +- A local jobs_start returns after durable acceptance; a remote request returns after signed publication with requested state. Never wait on Legacy Harness in the foreground. Use jobs_status or jobs_logs only for local facts from a later turn. Cancellation requires an authenticated controller or an authorized signed public cancel event; this model profile cannot cancel jobs. +- Never attempt a shell, Buzz CLI command, process launch, executable path, foreground lh invocation, file or git mutation, lifecycle shutdown, environment injection, or stdin payload. This profile intentionally provides none of those capabilities. +"#; diff --git a/crates/buzz-dev-mcp/src/managed_jobs.rs b/crates/buzz-dev-mcp/src/managed_jobs.rs new file mode 100644 index 00000000000..7e9d1e16056 --- /dev/null +++ b/crates/buzz-dev-mcp/src/managed_jobs.rs @@ -0,0 +1,289 @@ +use crate::collaboration::CollaborationClient; +use buzz_runtime::{ + protocol::{ + MAX_ARGV_ELEMENTS, MAX_ARG_BYTES, MAX_CWD_BYTES, MAX_JOB_ARGV_JSON_BYTES, + MAX_LOG_TAIL_LINES, MAX_SUMMARY_BYTES, + }, + JobId, JobStartRequest, JobState, RuntimeClient, +}; +use rmcp::ErrorData; +use schemars::JsonSchema; +use serde::Deserialize; +use uuid::Uuid; + +#[derive(Debug, Deserialize, JsonSchema)] +#[serde(deny_unknown_fields)] +pub(crate) struct JobsStartParams { + /// Channel UUID that owns the durable job. + pub channel_id: String, + /// Triggering Buzz event ID, when the job was requested from a message. + #[serde(default)] + pub source_event_id: Option, + /// Optional target managed agent.

53d39fad32d924684ff1301bd81c918a5b544918 Mon Sep 17 00:00:00 2001 From: Jacques Wainwright Date: Sat, 15 Aug 2026 20:01:37 +0200 Subject: [PATCH 11/13] fix(runtime): repair reconcile contract, sticky cancelling, bound constants, blocking log tail - Client reconcile() accepted only Ack while the server answers Jobs; accept Jobs and return the reconciled job list. - Late Progress(Running) after a cancel flipped cancelling back to running; mirror the Accepted-branch cancel_requested guard and add a Postgres-gated regression test. - Use MAX_PENDING_PER_CHANNEL / MAX_INBOX_RETRIES instead of drifting 500 / 10 literals in enqueue, requeue, and recover. - Wrap tail_rotating_log in spawn_blocking so the async control handler no longer blocks a tokio worker on sync file reads.

From 18f5c8ff45d820bc9171c38aa59988390abc72ef Mon Sep 17 00:00:00 2001 From: Jacques Wainwright Date: Sun, 16 Aug 2026 17:12:21 +0200 Subject: [PATCH 13/13] fix(runtime): add durable-store retention/compaction and scope FFI exceptions Blocker fixes for the #5954 review: - Retention/compaction: transactional compact() removes terminal inbox rows, terminal jobs (no linked active assignment) and assignments, and settled outbox rows past 7-day cutoffs; prunes cancel tombstones for jobs without live state back under the global cap so a long-lived runtime no longer permanently rejects new tombstones. One automatic pass per store-thread hour; compact_at() exposed for tests. Tests prove active work, replay fences and live jobs survive, terminal history is pruned, and the tombstone cap re-admits after compaction (store::tests:: compaction_preserves_active_work_and_fences). - unsafe scoping: Windows/macOS process-identity and Job Object FFI consolidated behind fn-scoped #[allow(unsafe_code)] citing the security decision issue block/buzz#6047, matching the existing buzz-dev-mcp shell.rs precedent; stray stmt-level allows removed. Gates: cargo clippy -p buzz-runtime -p buzz-acp --all-targets -D warnings clean; buzz-runtime 30+3+3+2+2 lib/integration tests pass; buzz-acp lib 839 pass.
