# ADR-001 — Workplan ID Prefix Convention

## Status

Accepted

## Context

`register_project.sh` derives the workplan prefix from the repo slug first token:
`coulomb-loop` → `COULOMB-WP`. The engagement workplans were authored as
`LOOP-WP-0001` through `LOOP-WP-0004` before registration, and state-hub
`fix-consistency` indexed them under those IDs.

Renaming to `COULOMB-WP` would churn 4 workstreams, 30 tasks, and cross-references
in INTENT.md with no functional benefit.

## Decision

Adopt **`LOOP-WP`** as the canonical workplan prefix for `coulomb-loop`.

- File pattern: `workplans/LOOP-WP-NNNN-<slug>.md`
- Task IDs: `LOOP-WP-NNNN-Tnn`
- Override the auto-derived `COULOMB-WP` in `.claude/rules/workplan-convention.md`

## Consequences

- Consistent with engagement naming ("loop" operations)
- state-hub workstream slugs remain `loop-wp-0001-*`
- Future coulomb_social repos (e.g. product apps) should use their own prefix
