refactor(state): use worktree-local QP state

[mosobande]

What

• use each working tree's ignored .qp/<owner-or-category>/ for local generated/project-support state
• treat a linked worktree and its .qp as one isolated candidate rather than redirecting state into the main checkout
• keep skill-owned state in concise homes such as .qp/atona/, .qp/architect/, .qp/iwadi/, .qp/se-triage/, .qp/seda-spec/, .qp/prototype/, .qp/ayewo-igba-ise/, and .qp/qp-setup/
• use semantic categories such as .qp/artifacts/, .qp/evidence/, .qp/handoffs/, or .qp/snapshots/ when no skill is the natural owner; no fixed registry/taxonomy is introduced
• keep producer instructions terse: name the destination and rely on the repository-level state convention instead of repeating storage policy
• keep disposable work in host/system temp and intentional project files at their natural project destination
• remove the obsolete generic QP workspace/settings model and the unreleased akosile skill, including its CAS/index runtimes, tests, dedicated CI, and workspace ADR
• make Atọ́nà retain execution workspace identity: absolute path, <branch-name> [main|worktree], and main-worktree path for a linked worktree
• make Atọ́nà reconcile relevant worktree-local .qp state before Closed, clean reconciled/disposable local state, record workspace disposition, and offer worktree removal with explicit user approval
• make Pepeye treat a worker worktree plus .qp as one candidate and hand accepted candidates to the accepting workflow for semantic reconciliation
• keep local plan projections aware of workspace paths while omitting machine-specific paths from portable/public projections by default
• keep QP Setup rollback data with the host it belongs to: Codex user backups under $CODEX_HOME/backups/qp-setup/ and repository backups under <repo>/.codex/backups/qp-setup/; future Claude host configuration follows the same host-local rule
• keep Kọ Skill focused on skill authoring: file-producing skills name their natural destinations, while runtime/worktree policy stays with repository instructions and runtime/lifecycle owners

Core contract

local state         → .qp/<owner-or-category>/
worktree + .qp      → one candidate
accepted candidate  → reconcile relevant .qp state
completed candidate → clean local .qp; offer worktree removal

There is no shared .qp, generic settings file, registry, central index, lock/CAS service, or automatic directory mirroring.

Ownership

• repository instructions → universal .qp convention
• Atọ́nà → initiative workspace identity, closure reconciliation, and cleanup
• Pepeye → delegated worktree candidate handoff/integration
• producing skills → only their natural output/state destination
• QP Setup → host-local setup state and rollback
• Kọ Skill → authoring/verification that skill instructions state the right destination; no runtime/worktree mechanics

Atọ́nà workspace shape

Main checkout:

workspace:
  path: /absolute/path/to/repo
  branch: ori [main]

Linked worktree:

workspace:
  path: /absolute/path/to/worktree
  branch: feature/example [worktree]
  main: /absolute/path/to/repo

At closure, relevant local state is reconciled into the accepting workspace and reconciled/disposable .qp state is cleaned from the completed candidate. The worktree may then be removed after explicit user approval or retained without blocking Closed.

Loss audit

• retired: unreleased Akọsílẹ̀ identity and scripts; generic QP settings/workspace; Git-common/shared-main-worktree storage; central record catalogue and dedicated CI
• relocated: universal state convention to repository instructions; delegated candidate lifecycle to Pepeye; initiative reconciliation/cleanup to Atọ́nà; destinations to natural producing owners; host rollback material to each host's own data/config directory
• preserved: skill-owned semantic records, intentional project destinations, exact candidate/authority rules at their natural owners, and explicit legacy-record support in Amọ̀ṣẹ́
