feat(gilbreth): add /wbs-migrate for the canonical-type migration#56
Merged
Conversation
Ships a one-shot, idempotent migration helper for workspaces bootstrapped on the pre-`core` shape (wbs-node/wbs-note types and wbs-* edges). The command rewrites frontmatter under wbs/**/*.md (type: wbs-node -> node, type: wbs-note -> note, eight legacy edge keys to their unprefixed canonical names), strips the legacy pack blocks from tusk.toml, installs Elephant's core pack + gilbreth's workflow-only wbs.toml via `tusk pack add --force`, and reindexes. Detection logic short-circuits on already-migrated workspaces so re-runs are a clean no-op. Pointer added to templates/wbs/conventions.md so consumers find the helper.

* chore(gilbreth): mark Elephant initiative and descendants complete Final status bump for the Elephant initiative, the gilbreth-refactor story, and the gilbreth-wbs project node. Shipped as a discrete commit ahead of the WBS tracking-tree retirement, per `conventions.md`'s "Retiring a completed project" procedure. * chore(gilbreth): retire completed Elephant WBS tracking tree The Elephant initiative shipped across PRs #45-49, #51-54, and #56 — all five stories (knowledge pack, conventions skill, capture skill, recall skill, gilbreth refactor) plus the Phase-3 /wbs-migrate helper. Initiative + descendants are all `status=completed`. Per `plugins/gilbreth/templates/wbs/conventions.md` "Retiring a completed project": once tracking files stop being coordination tools, they become noise for future agents querying the graph. This commit removes `wbs/gilbreth-wbs/` + `wbs/gilbreth-wbs.md` and moves the roadmap row to Done. Recoverable: every retired file is in git history (parent commit `3f5b9a0`). Spec/plan/brainstorm/reshape-audit notes are not lost, just no longer in the live graph.

Summary
/wbs-migrate, a slash command that performs the one-time migration of an existing Gilbreth WBS workspace from the legacywbs-*-prefixed Tusk types/edges to Elephant's canonicalcorepack (introduced in feat(elephant)!: canonical core type pack #53) consumed by gilbreth (feat(gilbreth)!: consume elephant core pack and defer conventions #54).templates/wbs/conventions.md.The command is additive — it doesn't change any existing behavior. Hence
feat(gilbreth):(not!-breaking).The procedure: rewrite
type: wbs-node/wbs-noteand the eightwbs-*edge keys (forward + inverse) acrosswbs/**/*.md, then swap the pack section intusk.toml(tusk pack add core --force→ strip legacy blocks →tusk pack add wbs.tomlso a failed core-add leaves a recoverable state), thentusk reindex. Idempotent: re-running on a migrated workspace is a no-op.Recoverability: every change is to git-tracked markdown /
tusk.toml, sogit restoreis always the rollback path. The command's pre-flight refuses to run on a dirty tree to keep that promise honest.Verified manually in a scratch workspace seeded with old-shape nodes + the pre-#54 wbs pack:
tusk doctorclean post-migration,tusk query 'type:node'returns the migrated nodes, edges intact, second run is a no-op.Test plan
