Self-audit of the previous draft surfaced 7 legacy residues that would
have left the rebuild short of the "optimal architecture" bar. Rewrite
the plan with those addressed:
1. Drop userId from data records entirely. Attribution lives in the
Actor system (__lastActor / __fieldActors). userId stays only on
explicitly user-scoped tables.
2. Active scene localStorage key becomes per-Space:
`mana:workbench:activeSceneId:${spaceId}` — switch Space A → scene
X, to B → scene Y, back to A → X restored.
3. New user-level userTagPresets table replaces the "copy from
Personal" checkbox hack. First-class templates for seeding new
Spaces with a named tag set; CRUD in Settings.
4. Encryption decision made in-line: globalTags + tagGroups names
encrypted during migration, not deferred (tag names like
"Therapie" or "Finanzen-privat" can leak personal categorization).
5. kontextDoc moves from user-level singleton to per-Space. AI runner
pulls the active Space's kontextDoc; Shared-Spaces start without
one until the user writes one.
6. Default-agent bootstrap uses SpaceType-aware names (Mana for
personal, Familien-Helfer for family, Team-Assistent for team,
etc.) so users don't end up with "three Mana" in their agent list.
7. Phase 1 explicitly audits every junction table to verify parent
records carry spaceId — no silent user-global references.
Also: an explicit "No legacy residues" section anchors these as
intentional anti-patterns to prevent drift. Success criteria now
includes "no table has both userId AND spaceId" as a testable
invariant.
Timeline grows from 3–4 to 4–5 days; the delta is encryption wiring
+ userTagPresets CRUD + the userId→Actor cleanup.

Supersedes per-space-vs-user-global-tags.md (which recommended defer
under "ship fast" assumptions). Pre-live + unlimited resources changes
the calculus: build the clean architecture now.
Decision: tags, tag-groups, workbench scenes, AI agents, and AI
missions all become Space-scoped. Only identity (user, session,
profile, MK key) and per-device UI prefs stay user-level.
Plan covers 8 phases across ~3–4 days:
1. Audit + schema design
2. Dexie migration (with backfill to user's Personal-Space)
3. Store APIs (implicit via scopedForModule wrapper)
4. Space-switch side-effects (reset active scene, bootstrap defaults)
5. Space-creation seeding (one-shot copy tags from Personal)
6. Backend (mana-sync + Postgres + RLS)
7. Docs + memory updates
8. Delete the old deferred plan
Includes edge cases, success criteria, and reasoning for why β over γ
(two clear levels beat one recursive primitive for user clarity).
