+# piker project store
+
+`current.org` contains the intact piker scope moved from the
+LNS working corpus. Task/checkbox states, carry metadata and prose
+remain human-owned. `sources.toml` selects this branch's store.
+
+Read the local `taken` skill through `.agents/skills/taken/SKILL.md`.
+It requires a complete-file revision guard for each authorized save.
+Use an explicitly selected source; do not write a global LNS copy.
+This migration preserves a historical project scope, not a claim that
+its old task descriptions or branch paths reflect current reality.
+
+The global storespace is registered in the LNS migration worktree's
+`taken/sources.toml`. Modden, Tractor and Piker include snapshots of their pre-existing
+local stores. The LNS consolidation ledger pins those inputs. Before
+landing, reconcile any newer edits there and retarget active agents;
+do not overwrite another agent's source or infer acceptance.
+
+Before removing this migration worktree after landing, update the
+global registration and the cross-repository taken skill link to the
+landed locations. The skill link intentionally points to the Taken
+migration branch until that code and documentation land.

+## Prompt
+
+Split the LNS working corpus into per-repository federated stores on
+open-wkt branches and connect them to one global storespace. Preserve
+human task states. Add a local agent workflow, update taken-export,
+and design rollover, supervised concurrency, activity and ranked views.
+
+## Response summary
+
+Create the repository's migration branch and preserve its imported
+scope, with revision-aware local source configuration and a shared
+local taken skill. Keep original checkout stores and indexes intact.
+Existing live branch stores remain independently registered. The LNS
+manifest and migration ledger describe the authoritative split paths.
+
+## Human edits
+
+The human chose the per-repo split and worktree delivery, authorized
+local auto-mode, and required supervisor-based locking: the supervisor
+owns write authority and can revoke delegated human/subagent edit
+grants through cancellation. The agent applied these directions.
+No task/checkbox acceptance changes or Git commits were authorized.
