Pure data model + CRUD -- no orchestration behavior yet (that's Phase 7b).
Revives ADR-007's stories concept (adapted; ADR-007 itself was deleted as
"more machinery than the usage pattern needed") while staying lean: reuses
the existing events/projects/task-tree machinery rather than building a
parallel hierarchy.
- internal/story: Epic/Story types. Epic is a loosely-scoped initiative
(OPEN/CLOSED, no execution semantics). Story is a shippable slice of work
realized by a task tree rooted at root_task_id; epic_id/project_id/
root_task_id are loose references (no FK enforcement, matching the
codebase's existing tolerance for unmatched reference strings like
tasks.project).
- storage: new epics/stories tables (additive migrations) + CRUD methods.
Story status is intentionally unvalidated pass-through in this phase --
no task.ValidTransition-style state machine, since there's no orchestrator
yet to make transitions meaningful.
- event: 9 new Kind constants for the ceremony this layer will eventually
drive (epic_proposed, discovery_proposed, framing_decided, groomed,
prioritized, eval_verdict, arbitration_decided, retro_captured,
human_accepted) -- defined but nothing emits them yet.
- api: GET/POST /api/epics, GET/PUT /api/epics/{id}, GET /api/epics/{id}/stories,
GET/POST /api/stories, GET/PUT /api/stories/{id}, and GET
/api/stories/{id}/task-tree -- BFS walk from root_task_id following both
parent_task_id children and depends_on-edge dependents (visited-set
guarded), returning a flat node list for a later UI phase to render as a
graph. Unauthenticated, matching the existing projects/tasks endpoints'
posture.
go build/vet/test -race -count=1 all pass, full suite.
