sb-ship — graduate, preserving history

Event-triggered when an Explore iteration meets the graduation gate. The one rule that matters: preserve the experiment — cp, never git mv. The Explore story stays as design history; git mv here is the destructive bug propagate-workflow.md exists to prevent. Load references/propagate-workflow.md before any Ship action — it's the only reference this skill needs; Do NOT load the sb-wrappers/sb-audit refs (lifecycle, galleries, composition) for a Ship.

Decide the path (ask yourself)

• Did the Explore define its own component file, or iterate on an existing one? → Path A vs Path B.
• Path B: evolve in place (B1) or keep V1 in _legacy/ (B2)? B2 only when V1 still has live callsites needing a migration window.
• Did the import path change? If yes → ast-grep callsites. If not → skip it.
• Other tagged stories that should flip? (a Compare decision:pending → decision:chosen + winner.)

Execute

• Path A — NEW component. cp the component explore→components, write a fresh production stories file to the recorded storiesLocation (.storybook/audit/status.md; the rule lives in CONTEXT.md §STORIES LOCATION — never scatter) — don't cp the Explore stories (production has different concerns: autodocs, no decision metadata), validate, then ast-grep callsites only if a path changed.
• Path B — UPDATE existing. Apply the Explore's diffs into the production component + stories in place; ast-grep only if the import path changed.
• Both — close the loop IN PLACE (no git mv): tags: ['explore','decision:chosen','archived','!autodocs','!test'] + parameters.decision = { status, winner, date, shippedTo }. Confirm with find-stories-by-tag.sh decision:chosen.

Gate + next

Run the bundled scripts/validate-stories.sh on the new production story (in the bundle: ${CLAUDE_PLUGIN_ROOT}/scripts/validate-stories.sh, or ${CLAUDE_PLUGIN_ROOT}/scripts/). Confirm the flip with scripts/find-stories-by-tag.sh decision:chosen. Append the decision to the ledger (templates/design-decisions.md); the graduated experiment stays put.

Re-enter the usage flow. A graduated component is new to src/ — it isn't in the rendered JSONs yet, so its Docs "Real usage" band and storyCoverage are blank. Trigger the one-command usage refresh (refresh-usage.sh, owned by sb-audit/sb-inventory) so the new component enters component-usage.json / project-inventory.json; a Storybook rebuild then shows its real usage. Then /sb-hub.
