Row 89, round 1. The broker's `tasks` read takes optional filter and page arguments and returns a short form. The harness adds `list_tasks` arguments (open tasks by default), a `get_task` tool, and compact JSON replies capped below the 50000-character threshold where Claude Code 2.1.296 saves a tool result to a file outside the workspace, which was the PM's fault in Jason's test. The bundle's tools line names the harness's own tools. Candidate manifest b8c5bb3a (agents/dewey/work/queue-89/), basea3f6e9e6, no drift on the 12 paths. Builder Dewey. Approved by Darkwing (comment 27940). Sage's gate onf04185fcplus the patch 2026-10-12T22:00:55Z-22:03:38Z: bus 108, harness 65, webui 86, cli 115, control-board 124, every scripts/test-*.sh green. Live at the next bus restart (broker) and role session launch (harness), both Mos's call (decision 109); Mos had the notice. Co-Authored-By: Claude Opus 5.5 <[email protected]>

|

// - register the session's typed tools, which call the runner's tool socket;
|
|
// - gate every tool call with gate.mjs (S0 lines 1 and 2: a block or a
|
|
// throw stops the tool);
|
|
// - write the turn marker on agent_end, so the runner can tell a finished
|
|
// turn from a pi that exited 0 mid-turn (S0 line 4).
|
|
// Missing or unreadable configuration throws here, which fails pi's start
|

// (S0 line 3): nothing is defaulted.
