§7 of the groups/project-tool design. A group node is now authoritatively managed by exactly one project-root; `pic apply --dir` claims, conflicts, takes over, and (with --prune) structurally reaps owned nodes. - Migration 0052: `projects(id, key UNIQUE)` + promote the inert `groups.owner_project` (0047) to a real FK (ON DELETE SET NULL) + index. - CLI mints a stable, gitignored project key in `.picloud/project.json` (`pic init`, or lazily on first tree plan/apply) and presents it on every tree request; `pic apply --dir --takeover` flag. - Server: prepare_tree resolves ownership read-only (plan surfaces conflicts + prune candidates; token folds each group's owner key). apply_tree upserts the project in-tx, claims created groups on insert, reconciles existing-group ownership under the per-node advisory lock (first-commit-wins), and prunes owned-but-undeclared groups leaf-first (delete=RESTRICT, never another repo's or a UI-owned node). - Authz (§7.4, ownership ⟂ RBAC): takeover requires GroupAdmin per contested node — enforced in authz_tree (pre-tx) AND re-verified in-tx at the ownership decision, so --force (which waives the staleness token) can't open a takeover-without-admin window. The attacker-supplied project key is length/charset-validated server-side. - Tests: tests/ownership.rs (claim → conflict → takeover → flip; non-admin takeover → 403; prune-owned-only); format_conflicts unit test; schema golden reblessed. tree_shape M2 journey updated to reparent in-place (a fresh dir is now a distinct project and would correctly conflict). Closes the M3 milestone; reviewed (4 findings: 1 authz-bypass via --force + key validation + 2 LOW, all fixed). M4 (trigger/route templates) remains.

-- Phase 5 / M3 (v1.2 Hierarchies): multi-repo single-owner ownership (§7).
|
|
--
|
|
-- A group node is authoritatively MANAGED by at most one project-root (the
|
|
-- repo whose manifest declares it as something it applies, not merely
|
|
-- references). `groups.owner_project` has carried this seam since 0047 as an
|
|
-- inert, FK-less UUID. M3 makes it a real reference: a `projects` table keyed
|
|
-- by a stable, gitignored project key the CLI mints in `.picloud/`, and a
|
|
-- foreign key from `groups.owner_project` to it.
|
|
--
|
|
-- Ownership is recorded at GROUP granularity; apps inherit their owning project
|
|
-- from their group (apps are never claimed directly). A NULL `owner_project`
|
|
-- means the node is UI/API-owned — no manifest fights it (§7.5). First apply
|
|
-- claims; a second project's apply to an owned node is refused unless
|
|
-- `--takeover` (group-admin gated). Ownership ⟂ RBAC: owning the manifest does
|
|
-- NOT grant write — the actor still needs the usual group capabilities (§7.4).
|
|
--
|
|
-- ON DELETE SET NULL: deleting a project row (not something the platform does
|
|
-- today) reverts its nodes to UI-owned rather than cascading away real groups.
