Brief: docs/plans/2026-10-12_pm-task-flow.md, section "PM task reads that fit a session". From Vikunja P19 #228 (Jason's first PM request, talk fef3fa41) and #228 c78.

list_tasks takes no arguments and returned about 120 KB; Claude Code saved it outside the PM's workspace and the file guard refused the read. Filters and paging on the broker's tasks verb (the no-argument reply unchanged for the Console), a get_task read, compact JSON and a reply cap below the CLI's save-to-file size with a narrow-the-query error.

Owner Dewey, reviewer Darkwing, gate Sage. Live at the next bus restart (decision 109). Blocks S7 (row 42).

Row 89 (#1583) round 1 review, Darkwing. Verdict: approve, with three notes, none blocking.

Candidate manifest b8c5bb3a881711ba1972697462e46d3b21b156e29230410be31bc1e03d839aef (12 paths, base a3f6e9e6). build.patch from agents/dewey/work/queue-89/ (commit 4a2e18c9) applies with git apply --index to a detached worktree of the base, and the manifest checks 12/12 OK. No commit from the base to refactor HEAD c76a92d8 touches the twelve paths.

What I checked

  • #tasks in broker.mjs: the no-argument read is still #taskRows; task_ref alone or invalid-request; every filter validated before use; tombstones out of filtered reads; total over the matches, next null on the last page. Text order in SQLite (ORDER BY task_ref, byte order) and JS > agree for the ASCII refs taskRef accepts.
  • callTool merges ARG_DEFAULTS under the session's own arguments, so done: true wins and a session can't reach the whole board through list_tasks. get_task maps to the same tasks verb with task_ref only. A tracker holder could already read every full row through list_tasks before this row, so get_task widens nothing.
  • replyText throws rather than cutting, in both servers; the MCP server turns the throw into isError, pi into a tool error. Tests cover both ends at the cap and one over.
  • The threshold work (binary, probe at 49990/50000/50010) and the 20% margin. The four limits are stated in the README.
  • 34 mutants, all killed, with the run 1 hang explained and the harness fixed.
  • Suites on the candidate in my worktree of the base, 21:36:33Z to 21:36:47Z: bus 108 pass, harness 65 pass, both rc=0. I didn't rerun your full gate.

Notes

N1. A number in a comment and in build.md. tools.test.mjs says "40000 units fit, though they are 80002 bytes", and build.md says the same. JSON.stringify("\u{1F600}".repeat(19999)) is 40000 units and 79998 bytes (node -e). The test is right either way, since 79998 is still over the cap; only the stated byte count is off.

N2. Row 92 lands near this one. Row 92 (#1586, mine, in review) edits the same harness README "Limits" list and puts a Claude Code session's HOME in its run directory. I applied row 92's patch and then this one to a worktree of HEAD: git apply --3way takes both cleanly. After row 92, a result the CLI saves goes under <run>/home/.claude/projects/, which is still outside the workspace, so the README's "a file outside the workspace" stays true. The probe's path, ~/.claude/projects/, is the unsandboxed one. On that combined tree (24 paths, at c76a92d8), bus 108, harness 65, cli 118 and seat 33 pass, 21:36:57Z to 21:37:30Z. Whichever row lands second should still rerun the gate on the tree it lands on.

N3. No test goes from the runner to a real broker for the two tools. The tools tests pin get_task and list_tasks to the tasks verb, and task-page.test.mjs drives the broker directly, so each half is covered. A runner test with a real broker would catch a verb name that drifts on one side only. A follow-up, not this row.

Row 89 (#1583) round 1 review, Darkwing. Verdict: **approve**, with three notes, none blocking. Candidate manifest `b8c5bb3a881711ba1972697462e46d3b21b156e29230410be31bc1e03d839aef` (12 paths, base `a3f6e9e6`). `build.patch` from `agents/dewey/work/queue-89/` (commit 4a2e18c9) applies with `git apply --index` to a detached worktree of the base, and the manifest checks 12/12 OK. No commit from the base to `refactor` HEAD `c76a92d8` touches the twelve paths. ## What I checked - `#tasks` in `broker.mjs`: the no-argument read is still `#taskRows`; `task_ref` alone or `invalid-request`; every filter validated before use; tombstones out of filtered reads; `total` over the matches, `next` null on the last page. Text order in SQLite (`ORDER BY task_ref`, byte order) and JS `>` agree for the ASCII refs `taskRef` accepts. - `callTool` merges `ARG_DEFAULTS` under the session's own arguments, so `done: true` wins and a session can't reach the whole board through `list_tasks`. `get_task` maps to the same `tasks` verb with `task_ref` only. A tracker holder could already read every full row through `list_tasks` before this row, so `get_task` widens nothing. - `replyText` throws rather than cutting, in both servers; the MCP server turns the throw into `isError`, pi into a tool error.

Landed in ce104b27 on refactor (Sage). This is row 89 round 1: candidate manifest b8c5bb3a, base a3f6e9e6, no drift. Approved by Darkwing (comment 27940). queue review verify-commit 89 ce104b27 matched all 12 paths. Sage's gate on f04185fc plus the patch ran 2026-10-12T22:00:55Z-22:03:38Z: bus 108, harness 65, webui 86, cli 115, control-board 124, and every scripts/test-*.sh green. Rev 788 (ac37cd17) moved row 89 to done.

The broker's tasks arguments go live at the next bus restart, and the harness tools at the next role session launch. Both restarts are Mos's call under decision 109. Mos had the notice before the landing.
