Local storage folder + free-tier preset sync (0.4.15-beta)#29
Merged
Conversation
…n-syx mirror A picked root folder gets two app-managed subfolders, served over /local/*: Presets/ — recursive .syx scan with an mtime-keyed decode cache (junk .syx negative-cached), on-demand byte reads, and sanitized or exact-path writes; Sync/ — an incremental plain-.syx + index.json mirror of the version store (tool-readable by FM3-Edit/Fractal-Bot), with a sha256-verified restore path (store.importVersion). Path-traversal-guarded throughout; atomic index writes; root lives in the never-synced 'local' doc collection.
Free accounts now sync preset versions within server-enforced limits (3 MiB stored · newest full-backup group · 5 snapshots). The old set-difference push would re-push pruned rows forever, so free sync reconciles the cloud to a target set (syncPlan.ts, pure + unit-tested): prune replaced rows first (the DB trigger demands delete-old-before-new), reference-count blobs by path, and pre-flight the deduped size before any write. Prune-guard: a downgraded account never loses data — over-quota pushes are refused, nothing is deleted silently. Pull stays unlimited. quota() RPC rides /cloud/status. 0.4.15-beta.

What
Local storage folder (
/local/*): a user-picked root with an app-managedPresets/.syx library (mtime-cached scans, on-demand reads, safe writes incl. exact-path write-back) and aSync/plain-syx mirror of the version store with sha256-verified restore.Free-tier preset sync: preset versions now sync for every account, reconciled to a target set (newest backup group + newest 5 snapshots, 3 MiB deduped cap) with a prune-guard so downgraded accounts never lose data. Pairs with the axis-cloud quota trigger; paid stays unlimited. Bumps to 0.4.15-beta.
Tests
npm test: 8/8 suites (adds api/local — 13 cases, api/syncplan — 7 plans).
