Inputs

Read in order; stop earlier when the batch is small enough that later inputs add no signal.

.context/business/business-feature-map.md + .context/business/business-data-map.md — domain vocabulary, entity model, CRUD matrix. Anchors refined ACs in real entities and flows.
.context/master-test-plan.md — regression Epic + in-scope modules. Tells the refinement whether the Story falls inside an already-prioritized area.
The Story's Acceptance Criteria + **Source spec:** reference on Jira. Detailed read via bun run jira:sync-issues get <STORY_KEY> --include-comments, then read the synced acceptance-criteria.md (+ description). NEVER acli view for custom fields. Canonical input — every refined AC must trace back here.
.context/PBI/epics/EPIC-<KEY>-<slug>/stories/STORY-<KEY>-<slug>/ if a PBI folder already exists for this Story (created by a prior /sprint-testing cycle). Carries earlier session notes worth honoring.
.agents/jira-workflows.json — Story workflow + valid transitions (backlog -> shift_left_qa -> estimation). Source of {{jira.transition.story.*}} slugs used in Phase 3.
.agents/jira-required.yaml — canonical slug catalog. Source of {{jira.acceptance_test_plan}} and other Jira field slugs touched in handoff.
