- Intake / Main-PM / Cell-PM prompts: enumerate independently-shippable work
units, inherit the breakdown down the chain, and dispatch independents in
parallel (dependency order, never one-at-a-time).
- Raise the code-spine concurrency cap from 1 to 2 per parent (one per cell
developer) so both devs build in parallel; keep the same-assignee guard and
the planning/documentation cap at 1, plus the cross-team planning exemption.
- Split-before-claim: hard-block an egregiously-bundled code leaf at delegate
time so the PM splits it before any dev claims it; nudge the moderate band
in the delegate success envelope.
Smoke-7: be-pm got the expected spine-cap rejection on a second
delegate. The remediate said "drive the existing sibling to
completion / cancel it, OR split this parent into two sibling
parents". The model read that, decided neither applied, and
"adapted" by re-delegating with task_type='documentation' as a
"verification subtask". The gateway accepted it (different type =
no cap collision) but the orphan subtask had no claimant — it
blocked submit_up forever with "subtasks not all terminal".
Two-layer fix:
1. _spine_type_dup_envelope remediate now explicitly forbids the
workaround: "DO NOT work around this by delegating again with a
different task_type (e.g. 'documentation' or 'research' as a
'verification' subtask). The lifecycle handles QA, documentation,
and PM-review automatically after the code subtask finishes —
you do not create auxiliary subtasks for those roles. Call
i_am_idle() now and wait for the existing child to come back."
2. cell_pm.md workflow step 6 strengthened to name the anti-pattern
explicitly: no verification subtask (QA is the verification step);
never re-delegate with a different task_type as a workaround.
3 new tests pin the remediate text: forbids workaround, names the
verification anti-pattern, retains invalid_state error kind.
