Migration 060 (paliad.user_pinned_projects): per-user, RLS owner-only, ON
DELETE CASCADE on both FKs.
PinService (Pin / Unpin / IsPinned / PinnedSet / ListPinned): visibility-
gates pin (can't pin what you can't see) but not unpin (so users can clean
up after losing access). PinnedSet returns a map for O(1) lookups during
tree stitching.
ProjectService.BuildTreeWithOptions extends BuildTree with chip-driven
filtering. New ProjectTreeNode fields are additive (Pinned,
InheritedVisibility, OpenDeadlinesSubtree, OverdueDeadlinesSubtree,
MatchKind) so the old BuildTree(ctx, userID) call still works for legacy
callers. New options:
Scope: All / Mine / Pinned (Mine + Pinned both expand to path-closure
with InheritedVisibility flag on greyed ancestors)
StatusIn / TypeIn: chip-narrowing whitelists
HasOpenDeadlines: per-node or subtree-aggregated, depending on
IncludeSubtreeCounts
SearchTerm: case-fold contains on title/reference/clientmatter, then
prune to {matches ∪ ancestors ∪ descendants} with match_kind tagged
IncludeSubtreeCounts: post-order DFS sums, O(N)
GET /api/projects/tree gains query params: scope, status, type,
has_open_deadlines, q, subtree_counts. Zero query string preserves
legacy behaviour.
POST/DELETE /api/projects/{id}/pin and GET /api/user-pinned-projects
wired. Service registered in cmd/server/main.go and dbServices.
build + vet clean.
