feat: projects — a saved filter over one global index, not a container A project is a named space set; querying one filters the single global index. The meta-project is an implicit filter at a reserved address rather than a row: a stored +everything would need a sync job on every space creation, and its one failure mode is silently omitting a space. SpaceFilter distinguishes All from an empty member list, because a freshly created project has no members and must mean selects-nothing. Collapsing the two would make every new project silently match the whole corpus.
feat: service — wiring, space lifecycle, read paths, push validation, reconciler Phase 1 of the implementation plan: the orchestration layer's read, validate and repair halves. The write plane (propose/merge) is Phase 3 and is absent. - Config/New assemble a Service from the shared config.ini, reporting every missing key in one message; TokenStore adapts db/ to authn.TokenStore, mapping db.ErrNotFound onto authn.ErrUnknownToken so an unknown credential is a 401 rather than a 503. - CreateSpace writes the repository first and the row second, removing the repository again if the insert fails; a crash between the two leaves content that is merely unlisted rather than a phantom space. - ReadDocument/ListDocuments/Policy/ResolveRev resolve the approved head or a pinned revision through one code path. - ValidatePush checks the refs rule first and unconditionally, then frontmatter and document-id uniqueness, which --push-option=skip-validation waives. The rejection is a structured, terminal-shaped message naming the document. - PlanRepairs is the repair table as a pure, table-tested function; Reconcile gathers the facts and applies them, listing stale-index spaces for Phase 2. Two departures from the design's repair table, both to stop the reconciler destroying live state, documented at their definitions: an open row with no branch is left alone inside a grace window (every propose passes through that state), and a branch still sitting on its recorded base is never treated as merged (its tip is trivially an ancestor of the approved head).
