superdesigndev/loopany/v0-1-0-to-v0-2-0

v0.1.0 → v0.2.0

The first big simplification. Borrowed from crewlet's loopany rewrite — fewer knobs, slugs as IDs, journal as the time spine.

What changed

• Kind frontmatter shrinks: drop idPrefix, bodyMode, storage,

idStrategy. Add optional slugLayout: 'flat' | 'year' (default flat).

• Slugs are IDs: no kind prefix. tsk-20260427-103045 → 20260427-103045,

prs-self → self. Globally unique across kinds (collision is a fail). Unicode allowed (CJK fine).

• Storage flattens: every artifact lives at

artifacts/<dirName>/<id>.md. The old artifacts/{YYYY-MM}/... time bucket is gone — time becomes a journal artifact.

• Frontmatter goes camelCase: check_at → checkAt,

for_date → forDate, target_skill → targetSkill.

• Auto `createdAt` / `updatedAt`: every write stamps these. Migration

derives createdAt from old timestamp IDs (or file mtime for slug IDs).

• `journal` kind: new auto-managed kind. One entry per day at

artifacts/journal/<YYYY>/<YYYY-MM-DD>.md. Migration backfills it from every existing artifact's createdAt.

Crewlet-specific extensions (lead, content-piece, signal UI fields like priority/actionableBy/impact/quickWin, task runtime fields like executor/prUrl/branchName) are deliberately not brought over — they're crewlet's domain, not loopany's core.

Why

The v0.1 model carried 4 nobs (idPrefix/storage/idStrategy/bodyMode) that nobody ever set differently. They added cognitive load to every kind file without expressing real choice. The journal design folds the time hierarchy into the same graph everything else uses — refs({id:'2026-05-06', direction:'out'}) is now "what happened that day" without any new query machinery.

See the upstream design at /Users/stonex/Workspace/primecrew/apps/crewlet/src/loopany/skills/core-artifacts/.

Pre-flight

# 1. Snapshot the workspace (recoverable rollback path)
cd $LOOPANY_HOME
git init -q 2>/dev/null || true
git add -A && git commit -q -m "pre-migration snapshot v0.1.0" || true
 
# 2. Capture the current state
loopany doctor > /tmp/loopany-pre-migration-doctor.txt 2>&1 || true
ls artifacts/ > /tmp/loopany-pre-migration-tree.txt

If doctor reports any fail checks already, fix those first — the migration assumes a healthy v0.1 workspace.

Steps

Run each script first without --apply (dry-run) and inspect the output. When it looks right, rerun with --apply. Scripts are idempotent — rerunning does no harm.

SKILL=skills/migrations/v0.1.0-to-v0.2.0/scripts
 
# 1. Snapshot — counts artifacts, validates IDs, flags collisions.
bun run $SKILL/01-snapshot.ts
 
# 2. Transform every artifact: rewrite frontmatter (snake → camel,
#    add createdAt/updatedAt/_backfilled), rename file, flatten dirs,
#    rewrite [[old-id]] wiki-links inside body.
#    Writes .migration-id-map.json to the workspace root.
bun run $SKILL/02-transform-artifacts.ts            # dry-run
bun run $SKILL/02-transform-artifacts.ts --apply
 
# 3. Rebuild references.jsonl with new IDs.
#    Uses .migration-id-map.json from step 2.
bun run $SKILL/03-rebuild-references.ts             # dry-run
bun run $SKILL/03-rebuild-references.ts --apply
 
# 4. Build journal entries — one file per date with backfilled artifacts
#    in `## Backfilled`.
bun run $SKILL/04-build-journal.ts                  # dry-run
bun run $SKILL/04-build-journal.ts --apply
 
# 5. Bump schemaVersion in config.yaml.
bun run $SKILL/05-bump-version.ts --apply
 
# 6. Refresh kinds/*.md from the bundled v0.2 definitions
#    (loopany init never overwrites — this step does).
bun run $SKILL/06-refresh-kinds.ts                  # dry-run
bun run $SKILL/06-refresh-kinds.ts --apply

After step 6, loopany doctor should pass cleanly with schema version: ok.

Rollback

cd $LOOPANY_HOME
git reset --hard HEAD                # back to pre-flight snapshot
rm -f .migration-id-map.json         # discard the in-progress map

If you've gone past git commit mid-migration, the snapshot still wins — all migration mutations are within the workspace tree.

Verification

loopany doctor                       # should be all green
loopany artifact list --kind task    # IDs no longer have `tsk-` prefix
loopany artifact list --kind journal # one entry per active date
ls $LOOPANY_HOME/artifacts/          # no {YYYY-MM}/ buckets, only kind dirs

Any loopany doctor failure should reproduce the exact symptom — file an issue with the doctor output and the contents of .migration-id-map.json.

Notes

• ID collisions: if two old artifacts strip down to the same slug

(e.g. mis-self and prs-self both → self), step 02 fails loud. Resolve by renaming one of the source files before running, e.g. mv artifacts/missions/mis-self.md artifacts/missions/mis-self-mission.md.

• `addresses` edges: stored in references.jsonl, rewritten in step 03.

No data is lost.

• `_backfilled: true`: every migrated artifact gets this flag — it's

honest about provenance and routes the artifact to the journal's ## Backfilled section instead of ## Activity.

• Scripts never import from `src/core/`: they parse the old format

directly so they remain runnable even when the binary no longer understands v0.1 files.
