Task: Scaffold story: Run a full report: scheduling, reporting and compute

(Describe what user-visible-or-internal change this task produces.)

(Implementation strategy. Written when work starts; key decisions are distilled into the parent story's * Decisions at close, but the plan itself stays — it is the historical record of what we did.)

Every number this task claims about a tree, with the command that produced it and the commit it was measured at. A number without both is not a measurement, because a clean-up record describes a tree and trunk moves under a branch: a consumer count, a gate's component count and a suite's size all change with no code changing, and the reader of a bare number cannot tell which tree it came from. Where the raw output matters, put it in an evidence/ file beside the task and name that file in the Command column.

Manual QA scenarios (scaffolded via compass add test_scenario) that verify this task. Link new ones here as they're created; the scenario doc itself links back via its "Verifies task" field.

Delivered. The story is wired into Sprint 26 with four tasks, and the target architecture is written as Report Processing, a knowledge page rather than a story document, because the target outlives the story. That page replaced an earlier single document, written under the same task, whose subject was the run's modes rather than the pipeline.

The story was framed as "integrate scheduling, reporting and compute". The design found that the integration already exists along one path — the shell can drive a batch to completion — and fails along the path the story needs, because the reporting to compute handoff publishes on a subject no wrapper subscribes to, leaves the workunit's fields empty, and hands over a URI in the wrong shape. That work is the ACME smoke-test story's and this one waits on it, recorded on the story so the dependency is visible rather than implicit.

Four tasks carry the rest: design, the execution mode together with role-addressed step results, demo mode end to end, and full mode. The fourth is deliberately deferred.
