From e2ab553977b6f37d05cbdbfb27147ffff1de23ab Mon Sep 17 00:00:00 2001 From: lukemaj Date: Tue, 29 Sep 2026 23:36:09 +0200 Subject: [PATCH] feat: planner-dispatch mode and dispatcher-mode comparison (#146) `submit --dispatcher planner` runs a job with the planner thread as its dispatcher. No dispatcher thread starts: each decision point (first dispatch, worker result, answer, refused completion, envelope repair) is posted into the planner thread, keyed by the action seq with its message id saved before the post, so a restarted controller watches the same post. A reply records planner_dispatch_reply with wait_secs; no reply blocks as planner_dispatch_pending, which recover continues. The planner's protocol carries #147's router-defect duty. A planner_question waits for the user (`answer` plus `recover`). Cancel never interrupts the planner thread. `luna` stays the default and its protocol text is unchanged. scripts/compare_dispatch.py reads jobs.db and Agent Observer's ledger read-only and reports, per mode, success rate, time to first worker and to a reviewed PR, and dispatch tokens by counter semantics.
