<!-- event: decision author: yoi-orchestrator at: 2026-06-23T05:54:11Z -->

## Decision

Routing decision: `implementation_ready_parallel`

Reason:
- Ticket body has concrete frontend requirements for Repository Ticket Kanban grouping, sort order, per-group independent scroll, lazy row loading, component boundary, and Deno/Nix validation。
- No relations / blockers / orchestration plan records exist。
- Active Ticket `00001KVSEBF56` is protocol TypeScript generation and is expected to touch protocol crate / generated types; this Kanban ticket primarily targets Workspace Repository page UI and can proceed in parallel with narrow frontend scope。
- Current queued Ticket is this Ticket only。
- Orchestrator worktree is clean on `orchestration` at `2865abb6`; target worktree / branch is not present。
- Current code map shows Repository Ticket Kanban is currently inline in `web/workspace/src/lib/workspace-pages/WorkspacePage.svelte`, using `repositoryTickets.columns` from `/api/repositories/local/tickets`。

IntentPacket:

Intent:
- Improve Repository Ticket Kanban display so high-volume states do not dominate the page, related states are grouped, and each group lazy-loads independently。

Binding decisions / invariants:
- Frontend display behavior only unless absolutely necessary; do not change Ticket lifecycle semantics or add mutation UI。
- Backend pagination is not required; frontend-only visible count per group is acceptable。
- Original Ticket state must remain visible on each row。
- Grouping is display-only: `planning+ready`, `queued+inprogress`, other states independent。
- Group sort priority: `ready` before `planning`, `inprogress` before `queued`。
- Each group has independent scroll/visible count state; scrolling one group must not increase other groups。
- Use existing design tokens from `web/workspace/src/app.css`; avoid raw colors and heavy card chrome。
- Keep static SPA / Deno tooling boundaries。
- Do not touch protocol TS generation scope from `00001KVSEBF56` unless unavoidable。

Requirements / acceptance criteria:
- `planning` and `ready` display in the same group, with `ready` above `planning`。
- `queued` and `inprogress` display in the same group, with `inprogress` above `queued`。
- `done`, `closed`, and other states keep independent display meaning。
- Each group has an independent scroll area approximately 10 rows tall。
- Initial visible rows per group are capped at 30。
- Near-bottom scroll within a group increases only that group’s visible count。
- `closed` or other high-volume group does not expand page height excessively。
- Row displays original Ticket state。
- Kanban display is preferably split into reusable Svelte component(s), moving grouping/sort/visible-count/scroll logic out of `WorkspacePage.svelte`。
- Deno check/build, `git diff --check`, and `nix build .#yoi --no-link` pass。

Implementation latitude:
- Component can live under `web/workspace/src/lib/workspace-pages/` or another clear frontend component path。
- Backend response shape may remain unchanged; grouping can be performed client-side from returned columns/items。
- Add minimal frontend tests only if current tooling supports it cheaply; otherwise validation via Svelte check/build is acceptable。
- CSS can be simple rule/typography/spacing approach; no need for full design system。

Escalate if:
- Svelte 5 event/scroll handling requires a broader frontend state management rewrite。
- Backend response shape prevents group-level lazy display without changing API semantics。
- Deno build/check breaks due unrelated protocol type generation work。

Validation plan:
- `cd web/workspace && deno task check && deno task build`
- `git diff --check`
- `cargo run -p yoi -- ticket doctor`
- `nix build .#yoi --no-link`
- `cargo test -p yoi-workspace-server` only if backend API changes。

## State changed

Human authorized queue routing from Workspace Dashboard. Ticket has concrete frontend acceptance criteria and no recorded blockers; active protocol TypeScript generation work is separate enough for parallel implementation.

## Implementation report

Implementation start report:

- Created child implementation worktree:
  - `/home/hare/Projects/yoi/.worktree/00001KVSGFM65-kanban-lazy-rows`
- Created branch:
  - `impl/00001KVSGFM65-kanban-lazy-rows`
- Base commit:
  - `a6f9019e ticket: accept kanban lazy rows`
- Confirmed tracked Ticket project records are visible in the child worktree。
- Confirmed `.yoi/memory` has no tracked/untracked entries in the child worktree check。
- Spawned sibling Coder Pod:
  - `yoi-coder-00001KVSGFM65`
- Coder scope:
  - read: `/home/hare/Projects/yoi`
  - write: `/home/hare/Projects/yoi/.worktree/00001KVSGFM65-kanban-lazy-rows`

Parallelization note:
- `00001KVSEBF56` remains active and targets protocol TypeScript generation. This Ticket should stay limited to Workspace Repository Ticket Kanban frontend display。

Next action:
- Wait for Coder implementation report, then spawn Reviewer read-only for the implementation diff。

## Implementation report

Coder implementation report received from `yoi-coder-00001KVSGFM65`.

Implementation commit:
- `6f68bb8d web: group repository ticket kanban rows`

Changed areas:
- `web/workspace/src/lib/workspace-pages/RepositoryTicketKanban.svelte`
  - New reusable Kanban component。
  - Groups `ready + planning`, with `ready` sorted above `planning`。
  - Groups `inprogress + queued`, with `inprogress` sorted above `queued`。
  - Keeps `done`, `closed`, and `other` as distinct display groups。
  - Shows each row’s original `ticket.state`。
  - Caps initial rendered rows per group at 30。
  - Adds independent per-group scroll/lazy row expansion。
  - Uses design tokens from `app.css`。
- `web/workspace/src/lib/workspace-pages/WorkspacePage.svelte`
  - Replaced inline Repository Ticket Kanban markup with extracted component。
- `web/workspace/src/app.css`
  - Removed now-unused global inline Kanban styles。

Coder validation reported:
- `cd web/workspace && deno task check`: passed
- `cd web/workspace && deno task build`: passed
- `git diff --check HEAD~1..HEAD`: passed
- `cargo run -p yoi -- ticket doctor`: passed
- `nix build .#yoi --no-link`: passed

Notes:
- No backend API changes; `cargo test -p yoi-workspace-server` was not run。
- No protocol TypeScript generation scope touched。

Orchestrator evidence checked:
- Worktree clean on `impl/00001KVSGFM65-kanban-lazy-rows` at `6f68bb8d`。
- Diff `a6f9019e..HEAD` touches expected frontend files only。
- `git diff --check a6f9019e..HEAD`: passed。
- Validation generated ignored frontend artifacts; Orchestrator removed `web/workspace/node_modules/`, `.svelte-kit/`, and `build/` before Reviewer routing。

Next action:
- Route to read-only Reviewer Pod for acceptance review。

## Review: approve

Verdict: `approve`

確認範囲:
- Ticket authority:
  - `.yoi/tickets/00001KVSGFM65/item.md`
  - `.yoi/tickets/00001KVSGFM65/thread.md`
- Diff `a6f9019e..6f68bb8d`:
  - `web/workspace/src/lib/workspace-pages/RepositoryTicketKanban.svelte`
  - `web/workspace/src/lib/workspace-pages/WorkspacePage.svelte`
  - `web/workspace/src/app.css`

Review evidence:
- Grouping/sort:
  - `planning` + `ready` are grouped as `ready-planning`, labelled `Ready / Planning`。
  - `queued` + `inprogress` are grouped as `inprogress-queued`, labelled `In progress / Queued`。
  - `statePriority()` places `ready` before `planning`, and `inprogress` before `queued`。
- Other states:
  - `done`, `closed`, and `other` remain separate group keys via `state:${state}` / `state:other`。
- Per-group lazy state:
  - `visibleRowsByGroup` is keyed by group key。
  - Initial visible rows are `INITIAL_VISIBLE_ROWS = 30`。
  - Scroll handling updates only `[group.key]`。
  - Near-bottom threshold is `NEAR_BOTTOM_PX = 96`。
- High-volume containment:
  - Each non-empty group row list has its own `.ticket-list-scroll`。
  - `.ticket-list-scroll` uses `max-height: 34rem; overflow-y: auto;`, so `closed` cannot expand page vertically without bound。
- Original row state:
  - Each ticket row renders `<span class="ticket-state">{ticket.state}</span>`。
- Component boundary:
  - Kanban logic and row rendering moved into `RepositoryTicketKanban.svelte`。
  - `WorkspacePage.svelte` now delegates with `<RepositoryTicketKanban tickets={repositoryTickets} />`。
- Design / boundary:
  - Styling uses existing CSS tokens such as `var(--space-*)`, `var(--line)`, `var(--text-muted)`, `var(--text-faint)`, `var(--text-strong)`。
  - No backend/API/protocol TypeScript generation scope touched。
  - No mutation UI added。

Blocking issues:
- None found。

Non-blocking concerns:
- No browser/manual scroll interaction test was run; validation is by code inspection plus Svelte check/build. Given the ticket’s frontend-only scope and current test tooling, this is acceptable。

Reviewer validation:
- `git diff --check a6f9019e..6f68bb8d`: passed
- `git diff --check a6f9019e..HEAD`: passed
- `cd web/workspace && rm -rf node_modules .svelte-kit build && deno task check && deno task build`: passed (`svelte-check found 0 errors and 0 warnings`; static build completed)
- `cargo run -p yoi -- ticket doctor`: passed (`doctor: ok`)
- `nix build .#yoi --no-link`: passed
- `cargo test -p yoi-workspace-server`: not run; no backend/API changes were made。

Generated artifacts:
- Ignored validation artifacts present after review:
  - `target/`
  - `web/workspace/.svelte-kit/`
  - `web/workspace/build/`
  - `web/workspace/node_modules/`
- No generated artifacts are tracked。

Worktree status:
- Clean tracked state on `impl/00001KVSGFM65-kanban-lazy-rows` at `6f68bb8d`。
