# Delegation intent: Ticket local files backend
## Classification
`implementation-ready` with a constrained design boundary.
The Ticket concept, split, and terminology have been accepted in the parent umbrella. This ticket should implement the first layer only: a typed Rust Ticket domain/backend and a LocalTicketBackend over the current `work-items/` files.
## Intent
Add a code-facing Ticket domain model and local files backend so yoi can read and mutate the current repository Ticket records without shelling out to `tickets.sh` or ad hoc parsing.
The durable orchestration concept is named `Ticket`. The current local storage directory remains `work-items/` for compatibility.
## Worktree / branch
- worktree: `/home/hare/Projects/yoi/.worktree/ticket-local-files-backend`
- branch: `work/ticket-local-files-backend`
## Requirements
- Add a new backend-shaped Rust layer for Tickets.
- Use `Ticket`, not `WorkItem`, as the public/domain concept name.
- Prefer a new lower-level workspace crate such as `crates/ticket` unless current code mapping reveals a better fit.
- Keep this crate independent from `pod` and `tui`.
- Implement `LocalTicketBackend` over current `work-items/` storage.
- Preserve compatibility with `tickets.sh` and existing `work-items/{open,pending,closed}/<id>/` layout.
- Preserve these local files:
- `item.md` with YAML-ish frontmatter and Markdown body;
- `thread.md` append-only event-ish log;
- `artifacts/` directory;
- `resolution.md` for closed tickets.
- Implement typed operations equivalent to:
- list;
- show;
- create;
- add event/comment for roles `comment`, `plan`, `decision`, `implementation_report`;
- review approve/request-changes;
- status transition across open/pending/closed;
- close with resolution;
- doctor/consistency check.
- Provide a thin typed envelope around Markdown/freeform content.
- Include fields useful for later Orchestrator/TUI/tool layers where practical:
- id / slug / title;
- status;
- kind / priority / labels;
- created_at / updated_at;
- readiness / needs_preflight / risk flags / action_required if present, while tolerating old tickets without them;
- event kind / review result.
- Keep unknown/extension values parseable rather than failing unnecessarily.
- Implement safe local mutation:
- path containment under configured root;
- atomic replace for file rewrites where practical;
- basic backend lock/conflict handling for concurrent Pod/tool callers;
- no writes outside the configured local ticket root except controlled temp files.
- Add focused tests using temp directories/fixtures; do not mutate real `work-items/` in tests.
- Keep `tickets.sh` command behavior intact.
## Non-goals
- Pod tools / built-in feature integration.
- Intake workflow/profile implementation.
- Orchestrator routing implementation.
- TUI UI changes.
- Renaming `work-items/` to `tickets/`.
- Removing or replacing `tickets.sh`.
- External tracker backends.
- Scheduler/lease/automatic maintainer behavior.
- Changing the session-local Task tool.
## Current code map
- `tickets.sh`
- Current authoritative mechanical behavior for local ticket creation/list/show/comment/review/status/close/doctor.
- Use it as compatibility reference, not as a runtime dependency for the Rust backend.
- `work-items/{open,pending,closed}/<id>/item.md`
- Ticket frontmatter and Markdown body.
- Required existing fields: `id`, `slug`, `title`, `status`, `kind`, `priority`, `labels`, `created_at`, `updated_at`, `assignee`, `legacy_ticket`.
- `work-items/{open,pending,closed}/<id>/thread.md`
- Current event log format uses HTML comments like `<!-- event: ... author: ... at: ... -->`, heading/body, and `---` separators.
- `work-items/{open,pending,closed}/<id>/artifacts/`
- Controlled artifact directory for a ticket.
- `work-items/closed/<id>/resolution.md`
- Resolution body for closed tickets.
- root `Cargo.toml`
- Add the new crate to workspace members.
- `work-items/open/20260601-031252-builtin-work-item-intake-routing/artifacts/ticket-definition-and-api-shape-20260605.md`
- Current conceptual Ticket definition/API direction.
## Suggested API shape
The exact API may be adjusted, but keep the layer backend-shaped:
```rust
trait TicketBackend {
fn list(&self, filter: TicketFilter) -> Result<Vec<TicketSummary>>;
fn show(&self, id: TicketIdOrSlug) -> Result<Ticket>;
fn create(&self, input: NewTicket) -> Result<TicketRef>;
fn add_event(&self, id: TicketIdOrSlug, event: NewTicketEvent) -> Result<()>;
fn review(&self, id: TicketIdOrSlug, review: TicketReview) -> Result<()>;
fn set_status(&self, id: TicketIdOrSlug, status: TicketStatus) -> Result<()>;
fn close(&self, id: TicketIdOrSlug, resolution: MarkdownText) -> Result<()>;
fn doctor(&self) -> Result<TicketDoctorReport>;
}
```
It is acceptable to expose concrete `LocalTicketBackend` methods first if trait object design becomes premature, but the code should not bake local paths into the Ticket concept types.
## Compatibility details to preserve
- `tickets.sh create` id format is `<YYYYMMDD-HHMMSS>-<slug>`.
- Status directories are `open`, `pending`, `closed`.
- `status` frontmatter must match containing directory.
- `doctor` checks required fields, id/directory match, duplicate ids/slugs, required files/directories, and legacy `tickets/*.md` references.
- `close` moves the ticket to `closed`, writes `resolution.md`, and appends a close event.
- `review` appends a review event with `status: approve` or `request_changes` in the event comment.
## Escalate if
- Preserving compatibility requires changing existing `tickets.sh` behavior.
- A strict typed schema would reject many existing tickets.
- The lock/atomic write approach requires a new dependency with license/packaging implications.
- The new crate needs to depend on `pod`, `tui`, or other high-level crates.
- Implementing all operations in one commit becomes too large; prefer a clean subset and report what remains.
## Validation
Run at least:
- new crate unit tests;
- compatibility tests that create/comment/review/status/close in temp dirs and verify `doctor` behavior;
- `cargo test -p ticket` or the chosen crate package name;
- `cargo check --workspace --all-targets`;
- `cargo fmt --check`;
- `git diff --check`;
- `./tickets.sh doctor`.
If feasible, run `nix build .#yoi` after the workspace check passes.

- worktree path / branch;
- commit hash;
- chosen crate/module name;
- public API summary;
- changed files;
- compatibility with `tickets.sh`;

# Implementation report: ticket-local-files-backend
## Worktree / branch
- Worktree: `/home/hare/Projects/yoi/.worktree/ticket-local-files-backend`
- Branch: `work/ticket-local-files-backend`
## Commit
- `740b017 feat: add local ticket backend`
## Summary
Added a new low-level `ticket` workspace crate that exposes a typed Ticket domain, `TicketBackend` trait, and `LocalTicketBackend` over the existing `work-items/` local markdown storage.
The implementation preserves the current local file layout and `tickets.sh` compatibility while making Ticket operations available as Rust API for later built-in tools, Intake workflow, and Orchestrator routing work.
## Public API / module summary
- `Ticket`, `TicketSummary`, `TicketMeta`, `TicketEvent`, `TicketReview`, `TicketArtifactRef`
- `TicketStatus`, `TicketEventKind`, `TicketReviewStatus`, `TicketKind`, `TicketPriority`
- `TicketIdOrSlug`, `TicketFilter`, `NewTicket`, `NewTicketEvent`
- `TicketBackend` trait
- `LocalTicketBackend`
- `TicketDoctorReport` / `TicketDoctorDiagnostic`
Implemented backend operations:
- `list`
- `show`
- `create`
- `add_event`
- `review`
- `set_status`
- `close`
- `doctor`
## Changed files
- `Cargo.lock`
- `Cargo.toml`
- `package.nix`
- `crates/ticket/Cargo.toml`
- `crates/ticket/src/lib.rs`
## Compatibility
- Keeps `work-items/{open,pending,closed}/<id>/item.md`, `thread.md`, `artifacts/`, and closed `resolution.md` layout.
- Rust-created tickets pass `tickets.sh doctor` in tempdir tests.
- `tickets.sh`-created tickets are readable by the Rust backend in tempdir tests.
- `tickets.sh` can mutate Rust-created tickets in tempdir tests.
- Real repository `./tickets.sh doctor` passed.
## Safety / scope
- New crate is lower-level and independent of `pod`, `tui`, Intake, Orchestrator routing, and scheduler code.
- No Pod tools or UI were added.
- No storage directory rename was introduced.
- Writes are constrained to configured backend root paths.
- Local backend uses a `.ticket-backend.lock` file for Rust backend caller coordination.
- File rewrites use temp files in the destination directory followed by rename where practical.
## Validation
Coder-reported validation passed:
- `cargo test -p ticket`
- `cargo check --workspace --all-targets`
- `cargo fmt --check`
- `git diff --check`
- `git diff --cached --check`
- `./tickets.sh doctor`
- `nix build .#yoi`
Reviewer-rerun validation passed:
- `cargo test -p ticket --no-run`
- `cargo test -p ticket`
- `cargo fmt --check`
- `git diff --check develop...HEAD`
- `./tickets.sh doctor`
- `cargo check --workspace --all-targets`
- `nix build .#yoi --no-link`
## Review status
External sibling reviewer approved with no blockers.
Non-blocker follow-ups:
- Event references are modeled but not persisted/parsed in `thread.md` yet.
- Extension enum variants should remain read-tolerant, while local write paths should avoid emitting values that `tickets.sh doctor` rejects unless the format is intentionally extended.
- Backend locking coordinates Rust backend callers, not concurrent direct `tickets.sh` writes.
- The inherited `thread.md` `---` separator remains ambiguous for event bodies containing standalone `---` lines.
## Ready for merge

# Review: ticket-local-files-backend
## 1. Result
approve
## 2. Summary of implementation
The implementation adds a new low-level `ticket` workspace crate with a typed Ticket domain, `TicketBackend` trait, and a filesystem-backed `LocalTicketBackend` for the existing `work-items/` directory layout. The crate is independent of `pod`, `tui`, scheduler/orchestrator, and intake UI/runtime code. It models tickets, events, reviews, statuses, artifacts, and doctor diagnostics, and provides operations for list/show/create/add_event/review/set_status/close/doctor.
The local backend writes the same file names and status directories used by `tickets.sh`:
- `work-items/{open,pending,closed}/<id>/item.md`
- `thread.md`
- `artifacts/`
- closed `resolution.md`
## 3. Requirement-by-requirement assessment
- Public/domain naming uses `Ticket`, not `WorkItem`: satisfied. Public names are `Ticket`, `TicketBackend`, `LocalTicketBackend`, `TicketStatus`, `TicketEvent`, etc.
- Crate/module placement: satisfied. `crates/ticket` is a low-level workspace crate and does not depend on `pod`, `tui`, or other high-level crates.
- Backend-oriented API shape: satisfied for this ticket. Local path concepts are mostly confined to `LocalTicketBackend`, `TicketArtifactRef`, and filesystem operations; core ticket/status/event metadata remains backend-neutral.
- Current layout compatibility: satisfied. The implementation preserves the status directories and expected markdown files, including `resolution.md` on close.
- Operation coverage: satisfied for this ticket. The backend covers list/show/create/add_event/review/set_status/close/doctor and includes diagnostics rather than hard failures for malformed existing records.
- Existing old/minimal frontmatter readability: satisfied. Parsing tolerates missing optional readiness/action-required/risk fields and unknown/extension metadata values.
- Markdown/freeform bodies: satisfied for `item.md` bodies and normal event/resolution bodies. See residual risk for the inherited `thread.md` delimiter limitation.
- Path containment/id safety/atomic-ish writes/locking: acceptable for a local-files MVP. IDs are validated as path components, writes are staged through temp files in the destination directory then renamed, and backend operations take an exclusive backend lock.
- Tests do not mutate real `work-items/`: satisfied. Tests use temp directories and pass an explicit `WORK_ITEMS_DIR` to `tickets.sh` compatibility checks.
- Tests exercise `tickets.sh` compatibility: satisfied. The tests create and mutate temp work item trees through both the Rust backend and `tickets.sh`, then run/show/doctor against the same layout.
- `Cargo.lock` / `package.nix`: acceptable. The new crate and `fs4` lock dependency require workspace/package metadata updates; `nix build .#yoi --no-link` passed.
- Scope control: satisfied. I did not find Pod tools, intake workflow routing, orchestrator scheduling, TUI UI, storage rename, or unrelated refactors in the implementation.
## 4. Blockers
None.
## 5. Non-blockers / follow-ups
- `NewTicketEvent.references` / event references are modeled but not visibly persisted into or parsed from `thread.md`. That is acceptable for this backend MVP, but follow-up work should either define a compatible markdown representation or keep references as higher-level metadata outside the shell-compatible thread format.
- Extension/unknown enum variants are useful for reading older/future files, but local write paths should remain careful not to emit values that `tickets.sh doctor` would reject unless the file format is intentionally extended.
- The backend lock coordinates Rust backend callers, but it cannot coordinate concurrent direct `tickets.sh` writes. That is acceptable for this compatibility bridge, but users should not assume cross-tool transactional safety yet.
## 6. Validation assessed or rerun
Reviewed:
- Ticket item, delegation intent, parent Ticket definition/API shape, and `tickets.sh` compatibility reference.
- Diff against `develop...HEAD` for the implementation branch.
- New crate placement and workspace/package metadata.
- Local backend read/write, parser, status transition, close, doctor, and tests.
Reran from `/home/hare/Projects/yoi/.worktree/ticket-local-files-backend`:
- `cargo test -p ticket --no-run`
- `cargo test -p ticket`
- `cargo fmt --check`
- `git diff --check develop...HEAD`
- `./tickets.sh doctor`
- `cargo check --workspace --all-targets`
- `nix build .#yoi --no-link`
All commands completed successfully.
## 7. Residual risk
The `thread.md` format still uses plain `---` event separators, so an event body containing a standalone `---` line remains ambiguous. This appears inherited from the current shell-compatible storage format rather than introduced by the new crate, and should be handled deliberately if future typed consumers require lossless arbitrary markdown event bodies.
