+# Delegation intent: remove `tickets.sh`
+
+## Classification
+
+`implementation-ready` after storage migration.
+
+The prerequisite migration is complete: active Ticket records live under `.yoi/tickets/`, the Rust `yoi ticket` CLI has parity, and `tickets.sh` is only a transitional shim. Keeping it now leaves an unnecessary second mutation path.
+
+## Intent
+
+Delete `tickets.sh` and update active documentation, project instructions, tests, and validation references so the repository uses the typed Rust Ticket backend through `yoi ticket ...` and Ticket tools.
+
+## Worktree / branch
+
+- worktree: `/home/hare/Projects/yoi/.worktree/remove-tickets-sh`
+- branch: `work/remove-tickets-sh`
+
+This ticket will edit tracked `.yoi/tickets` records and may edit `.yoi/ticket.config.toml` only if necessary. Do not read or edit `.yoi/memory/`; it is ignored generated memory state and is not part of this cleanup.
+
+## Requirements
+
+- Delete repository-root `tickets.sh`.
+- Remove or update every active doc/workflow/test/project-instruction reference that tells users, maintainers, or agents to run `./tickets.sh`.
+- Replace validation examples with `yoi ticket doctor`.
+- Replace lifecycle examples with `yoi ticket create/list/show/comment/review/status/close/doctor`.
+- Remove shell compatibility tests that execute `tickets.sh`, or port them to Rust backend / `yoi ticket ...` coverage.
+- Ensure no production code shells out to `tickets.sh`.
+- Preserve historical Ticket thread/artifact references when they are closed historical context; do not mass-rewrite old records just for path hygiene.
+- Keep `.yoi/tickets/` as the active storage root and avoid reintroducing `work-items/` as mutable storage.
+- Update `work-items/README.md` so it no longer points to the transitional script.
+
+## Active references to inspect/update
+
+Current active references include at least:
+
+- `AGENTS.md`
+  - currently says `.yoi/tickets/` and `tickets.sh` are authoritative and lists `./tickets.sh ...` commands.
+  - Update to `yoi ticket ...` as the command path; `.yoi/tickets/` remains storage/project-record authority.
+- `README.md`
+  - update dogfooding/doctor examples from `./tickets.sh doctor` to `yoi ticket doctor`.
+- `docs/development/work-items.md`
+  - remove the `tickets.sh` maintainer CLI section or turn it into a historical note only if needed.
+  - normal user path remains TUI role actions / Ticket tools / workflows.
+- `docs/development/validation.md`
+  - update validation command examples.
+- `crates/workflow/README.md`
+- `crates/lint-common/README.md`
+- tests under `crates/ticket` that mention or execute `tickets.sh`.
+
+Historical/closed records and old report artifacts may still mention `tickets.sh` or `work-items/`; leave them alone unless an active test/doc depends on them.
+
+## Non-goals
+
+- Moving storage; already done.
+- Adding Ticket backend features.
+- TUI UI changes.
+- External tracker/provider support.
+- Rewriting closed historical Ticket threads/artifacts.
+
+## Validation
+
+Run at least:
+
+- `cargo test -p ticket`
+- `cargo test -p yoi ticket`
+- `cargo test -p pod ticket --lib`
+- `cargo check --workspace --all-targets`
+- `cargo fmt --check`
+- `git diff --check`
+- `cargo build -p yoi`
+- `target/debug/yoi ticket doctor` or built binary equivalent
+
+Run `nix build .#yoi --no-link` if feasible.
+
+Also manually check:
+
+- `test ! -e tickets.sh`
+- `rg "tickets\.sh|./tickets.sh"` only returns closed historical records/report artifacts, or no active references.
+- No active docs/workflows/AGENTS instructions present `tickets.sh` as a command.
+- No tests or production code execute `./tickets.sh`.
+
+## Completion report
+
+Report:
+
+- worktree path / branch;
+- commit hash;
+- deleted script path;
+- tests/docs/instructions updated;
+- remaining `tickets.sh` references and why they are historical/acceptable, if any;
+- validation results;
+- whether the umbrella `yoi-local-ticket-backend-migration` can be closed.

+## Plan
+
+Preflight result: `implementation-ready` after storage migration.
+
+`yoi ticket` has parity and active storage has moved to `.yoi/tickets/`, so `tickets.sh` should now be removed to eliminate the temporary second mutation path. Active docs/project instructions/tests should use `yoi ticket ...`; historical closed records and old report artifacts do not need mass rewriting.
+
+Detailed delegation intent is recorded in `artifacts/delegation-intent.md`.
