## Workplan Convention (ADR-001)

File location: `workplans/{WP_PREFIX}-NNNN-<slug>.md`
ID prefix: `{WP_PREFIX}-`

Work items originate as files in this repo **before** being registered in the hub.

Canonical workplan frontmatter statuses are:
`proposed`, `ready`, `active`, `blocked`, `backlog`, `finished`, `archived`.
Use `proposed` for a newly drafted plan, `ready` after review against current
repo state, and `finished` when implementation is complete. `stalled` and
`needs_review` are derived health labels, not stored statuses.

Closed workplans may be moved to `workplans/archived/` with a completion-date
prefix: `YYMMDD-{WP_PREFIX}-NNNN-<slug>.md`. The frontmatter id remains
unchanged; the prefix is only for quick visual reference.

Small opportunistic tasks discovered during another session use **Ad Hoc Tasks**:
`workplans/ADHOC-YYYY-MM-DD.md`, workplan slug `adhoc-YYYY-MM-DD`, and task ids
`ADHOC-YYYY-MM-DD-T01`, `T02`, etc. Use adhocs only for low-risk work completed
directly. Promote anything requiring analysis, design, approval, dependencies, or
multiple planned phases into a normal workplan.

Ecosystem todos from other agents arrive as `[repo:{REPO_SLUG}]` hub tasks —
visible at session start. Pick one up by creating the workplan file, committing,
and running `statehub fix-consistency` — C-06 registers the workplan in the hub.
Never register by hand with `create_workplan`/`create_workstream`.

Task blocks use this shape:

```task
id: {WP_PREFIX}-NNNN-T01
status: wait | todo | progress | done | cancel
priority: high | medium | low
state_hub_task_id: "<uuid>"         # written by fix-consistency — do not edit
```

Status progression is `todo` → `progress` → `done`; use `wait` for waiting or
blocked work and `cancel` for stopped work.

Workplan frontmatter carries `state_hub_workstream_id` — a legacy field name
kept for compatibility ("workstream" is the old term for workplan); it holds
the hub workplan id and is written by fix-consistency. Do not edit or rename it.
