+## Decision
+
+Routing decision: `wait_do_not_parallelize_with_sidebar`
+
+Reason:
+- Ticket body is implementation-ready in isolation, but it is directly coupled to the currently active sidebar navigation work `00001KVNG9B9Z`。
+- Relations show this Ticket is related to `00001KVNG9B9Z` with note: “Sidebar navigation should link to repository and objective pages”。
+- `00001KVNG9B9Z` is already `inprogress`, has a live Coder Pod, and is expected to change `web/workspace/src/routes/+page.svelte` / sidebar component structure。
+- Starting this Ticket in parallel now would likely produce overlapping route/layout/sidebar changes and non-trivial semantic merge work, rather than independent implementation。
+- Host/Worker API work `00001KVNEKH9Q` just landed, further increasing the need to base the page/navigation work on current SPA state。
+
+Decision:
+- Do not create a worktree or spawn Coder for `00001KVNGJPRG` yet。
+- Leave Ticket `queued` and record an orchestration `do_not_parallelize` note with `00001KVNG9B9Z`。
+- Re-route this Ticket after sidebar work lands, or if sidebar implementation report shows a stable component boundary that makes repository/objective pages non-conflicting。
+
+No implementation side effects were performed for this Ticket。

+## Implementation report
+
+Coder conflict-resolution report received from `yoi-coder-00001KVNG9B9Z`.
+
+Final implementation HEAD:
+- `4ab696b4` merge commit from current `orchestration` into `impl/00001KVNG9B9Z-workspace-sidebar`
+
+Relevant commits:
+- `d3b8bdfd feat: add workspace sidebar skeleton`
+- `4ab696b4` merge/conflict-resolution commit
+
+Conflict resolution summary:
+- Resolved `web/workspace/src/routes/+page.svelte` conflict after Host/Worker API/UI from `00001KVNEKH9Q` landed。
+- Preserved merged Host/Worker main content/cards/table。
+- Preserved sidebar navigation skeleton。
+- Updated sidebar Workers section to consume available `/api/workers` response through typed `ListResponse<Worker>`。
+- Kept Pod naming out of sidebar, presenting workers by label/state/status/role。
+- Changes remain scoped to Workspace frontend。
+
+Coder validation reported:
+- `cd web/workspace && deno task check`: passed
+- `cd web/workspace && deno task build`: passed
+- `git diff --check`: passed
+- `git diff --check orchestration..HEAD`: passed
+- `cargo run -p yoi -- ticket doctor`: passed
+- `nix build .#yoi --no-link`: passed
+- `cargo test -p yoi-workspace-server`: not run because backend code was not changed during conflict resolution
+
+Generated artifact cleanup:
+- Coder removed generated/ignored frontend artifacts after validation:
+  - `web/workspace/.svelte-kit`
+  - `web/workspace/build`
+  - `web/workspace/node_modules`
+
+Orchestrator evidence checked:
+- Worktree clean on `impl/00001KVNG9B9Z-workspace-sidebar` at `4ab696b4`。
+- Diff `orchestration..HEAD` touches expected frontend files only: new `web/workspace/src/lib/workspace-sidebar/*` components and `web/workspace/src/routes/+page.svelte`。
+- `git diff --check orchestration..HEAD`: passed。
+- Merge-tree conflict scan vs current `orchestration`: no conflict markers / no changed-in-both diagnostics。
+
+Next action:
+- Route to read-only Reviewer Pod for acceptance review。

+- Primary review diff: `orchestration..HEAD` inside implementation worktree, so review sees final sidebar changes on top of current Host/Worker API/UI state。
+
+Reviewer scope:
+- read-only `/home/hare/Projects/yoi`
+
+Reviewer focus:
+- Sidebar visibility/layout/responsive behavior。
+- Workspace header/settings placeholder。
+- Repositories/objectives/workers sections。
+- Objective and worker section bounded loading/empty/error handling。
+- Worker naming avoids Pod-primary UI。
+- Main Host/Worker content from `00001KVNEKH9Q` remains preserved after conflict resolution。
+- No backend authority/SSR/business logic changes。

+Orchestrator will wait for reviewer verdict before integration。

+  - `crates/workspace-server/src/hosts.rs`
+  - `crates/workspace-server/src/records.rs`
+
+Blocking issues:
+- None。
+
+Acceptance verification:
+- Left sidebar is wired into `+page.svelte` and layout is separated from main content。
+- Sidebar header shows workspace label/name and disabled settings placeholder。
+- `repositories`, `objectives`, and `workers` sections are present。
+- Objectives section fetches `/api/objectives` and handles loading/error/empty locally。
+- Workers section fetches `/api/workers`, uses Worker naming in visible UI, and handles 404/empty/error locally。
+- Main Host/Worker content from current orchestration branch is preserved。
+- No backend/API authority changes were introduced by the implementation-only diff。
+- Responsive CSS uses a two-column layout on wide viewports and single-column layout below 760px, with `min-width: 0`, wrapping, and table overflow containment。
+
+Non-blocking concerns:
+- `orchestration..HEAD` currently shows apparent `.yoi/tickets/00001KVNG9B9Z/item.md` / `thread.md` reversions because `orchestration` has newer review-routing/report commits after the implementation branch’s merge-base. The implementation-only diff against the merge-base is frontend-only, and `git merge-tree --write-tree orchestration HEAD` reports a clean merge. This should not block a normal merge, but avoid applying the literal `orchestration..HEAD` patch/squash in a way that drops newer ticket thread entries。
+
+Reviewer validation:
+- `git diff --check`: passed
+- `git diff --check orchestration..HEAD`: passed
+- `git diff --check $(git merge-base orchestration HEAD)..HEAD`: passed
+- `cd web/workspace && deno task check`: passed (`svelte-check found 0 errors and 0 warnings`)
+- `cd web/workspace && deno task build`: passed; static adapter wrote site to `build`
+- `cargo run -p yoi -- ticket doctor`: passed (`doctor: ok`)
+- `nix build .#yoi --no-link`: passed
+- `cargo test -p yoi-workspace-server`: passed (`6 passed; 0 failed`)
+- `git merge-tree --write-tree orchestration HEAD`: passed with status 0; produced merged tree `24e0e026264333fc63d60c0e2d649839445acb64`
+
+Generated artifacts:
+- Reviewer did not clean generated ignored artifacts after validation:
+  - `web/workspace/.svelte-kit/`
+  - `web/workspace/build/`
+  - `web/workspace/node_modules/`
+- They are ignored and not tracked; `git ls-files --others --exclude-standard` reports `0`。

+## Decision
+
+Routing decision: `implementation_ready_after_sidebar_landed`
+
+Reason:
+- This Ticket was previously left queued due `do_not_parallelize` with `00001KVNG9B9Z` because repository/objective pages and sidebar navigation both touched the Workspace SPA navigation/layout surface。
+- `00001KVNG9B9Z` is now `closed` and integrated (`613f4126 merge: workspace sidebar navigation`), so the sequencing blocker is cleared。
+- Related bootstrap Ticket `00001KVMFFYVX` is also closed/integrated。
+- Ticket body has concrete backend/API/frontend requirements, acceptance criteria, and validation requirements。
+- Relations are `related` only; no blocking relation remains。
+- Orchestrator worktree is clean on `orchestration` at `eb2e5907`; target worktree / branch is not present。
+
+IntentPacket:
+
+Intent:
+- Add Repository and Objective pages reachable from the Workspace sidebar, using filesystem read-through Ticket/Objective authority and bounded read-only Repository/Git summaries。
+
+Binding decisions / invariants:
+- Ticket / Objective canonical authority remains existing filesystem records; do not migrate canonical writes to SQLite or add mutation APIs。
+- Repository page is read-only initial slice for current workspace root as local Repository。
+- Git info and log summaries must be bounded; do not expose full diffs, file contents, blame, or secret-like config。
+- Repository Ticket Kanban is read-only and grouped by Ticket state; no drag/drop or state mutation。
+- Objective list uses existing filesystem read-through `/api/objectives` data, with detail links/placeholders as practical。
+- Frontend remains static SPA; no SSR/business authority。
+- Sidebar links should use the now-landed navigation/component structure。
+- API failures, non-Git repo, and empty state must be section-local。
+
+Requirements / acceptance criteria:
+- Add read-only Repository list/detail/summary API or minimal workspace repository summary。
+- For Git repository: bounded branch/head/root/dirty/remote/recent log summary。
+- For non-Git repository: safe `kind = local` / git unavailable diagnostic。
+- Add bounded Git log summary API returning recent N commit hash/subject/author/timestamp only。
+- Add Repository Ticket Kanban read model grouped by Ticket state, with safe fallback to workspace-local tickets when target metadata is absent。
+- Add Repository page showing summary, Git summary/log, and Ticket Kanban。
+- Add Objective list page showing objective title/state/updated_at/summary and detail link/placeholder if feasible。
+- Sidebar repositories/objectives links navigate to these pages。
+- Deno check/build and backend validation pass。
+
+Implementation latitude:
+- Use SvelteKit static SPA client-side routing/hash/router approach or simple stateful navigation if current skeleton lacks route generation; keep static output compatible。
+- Backend API names may be pragmatic, e.g. `/api/repositories`, `/api/repositories/{id}`, `/api/repositories/{id}/log`, `/api/repositories/{id}/tickets`。
+- Current workspace root can be the only repository for this slice。
+- Ticket Kanban fallback can group all workspace tickets by state with diagnostic that target metadata is not yet available。
+- Keep UI simple and avoid broad design-system churn。
+
+Escalate if:
+- Implementing repository APIs would require reading file contents/diffs or unsafe Git config/secrets。
+- Objective detail requires mutation or schema changes。
+- Static SPA route approach conflicts with SvelteKit adapter/static constraints。
+- Sidebar/navigation architecture from `00001KVNG9B9Z` cannot support pages without broad rewrite。
+
+Validation plan:
+- `cargo fmt --check`
+- `cargo test -p yoi-workspace-server`
+- `cargo check -p yoi-workspace-server`
+- `cd web/workspace && deno task check && deno task build`
+- `git diff --check`
+- `cargo run -p yoi -- ticket doctor`
+- `nix build .#yoi --no-link`。

+## Implementation report
+
+Coder implementation report received from `yoi-coder-00001KVNGJPRG`.
+
+Implementation commit:
+- `ceb1ee3b feat: add repository objective pages`
+
+Changed areas:
+- Backend repository read APIs:
+  - Added `crates/workspace-server/src/repositories.rs`。
+  - Added bounded local repository/Git summary and log reader。
+  - Added endpoints:
+    - `/api/repositories`
+    - `/api/repositories/local`
+    - `/api/repositories/local/log`
+    - `/api/repositories/local/tickets`
+  - Added read-only Ticket Kanban grouping by Ticket state with workspace-local fallback diagnostic。
+  - Added Objective list summaries from existing filesystem Objective records。
+- Frontend Workspace SPA:
+  - Added hash-navigation pages for Repository and Objectives。
+  - Wired sidebar Repository/Objectives links to the new pages。
+  - Added Repository summary, Git summary/log, diagnostics, and read-only Ticket Kanban UI。
+  - Added Objective list with title/state/updated_at/summary and detail placeholder links。
+- Tests:
+  - Extended workspace-server API tests for repository endpoints and Objective summary。
+  - Added Git URL sanitization/log parsing unit tests。
+
+Coder validation reported:
+- `cargo fmt --all`: passed
+- `cargo fmt --check`: passed
+- `cargo test -p yoi-workspace-server`: passed
+- `cargo check -p yoi-workspace-server`: passed
+- `cd web/workspace && deno task check`: passed
+- `cd web/workspace && deno task build`: passed
+- `git diff --check`: passed
+- `cargo run -p yoi -- ticket doctor`: passed
+- `nix build .#yoi --no-link`: passed after staging newly added `repositories.rs` so Git-backed flake source filtering included it。
+
+Generated artifact cleanup:
+- Coder removed `web/workspace/build` and `web/workspace/.svelte-kit`。
+- Orchestrator additionally removed ignored `web/workspace/node_modules/` before Reviewer routing。
+
+Orchestrator evidence checked:
+- Worktree clean on `impl/00001KVNGJPRG-repository-objective-pages` at `ceb1ee3b`。
+- Diff `0f7e78c1..HEAD` touches 8 expected backend/frontend files, about 1228 insertions / 142 deletions。
+- `git diff --check 0f7e78c1..HEAD`: passed。
+- No generated frontend artifacts remain in child worktree status。
+
+Next action:
+- Route to read-only Reviewer Pod for acceptance review。

+
+## Review: approve
+
+Verdict: `approve`
+
+確認範囲:
+- Ticket authority:
+  - `.yoi/tickets/00001KVNGJPRG/item.md`
+  - `.yoi/tickets/00001KVNGJPRG/thread.md`
+- Diff `0f7e78c1..ceb1ee3b`:
+  - `crates/workspace-server/src/lib.rs`
+  - `crates/workspace-server/src/records.rs`
+  - `crates/workspace-server/src/repositories.rs`
+  - `crates/workspace-server/src/server.rs`
+  - `web/workspace/src/lib/workspace-sidebar/ObjectivesNavSection.svelte`
+  - `web/workspace/src/lib/workspace-sidebar/RepositoriesNavSection.svelte`
+  - `web/workspace/src/lib/workspace-sidebar/types.ts`
+  - `web/workspace/src/routes/+page.svelte`
+
+Blocking issues:
+- None found。
+
+Acceptance verification:
+- Repository APIs are read-only `GET` routes only。
+- Git commands use fixed argument vectors through `Command::new("git").arg("-C").arg(workspace_root).args(args)`; no shell interpolation。
+- Git summary/log is bounded:
+  - log limit clamps to `1..=50`
+  - command output capped at `4096`
+  - fields capped at `240`, hash at `40`
+  - no diff/patch/file content/blame/config commands are used。
+- Remote URL summary strips URL-scheme userinfo and marks `redacted`。
+- Non-Git workspaces return `git.status = "unavailable"` plus diagnostics rather than failing the Repository page model。
+- Ticket Kanban reads filesystem Ticket summaries and groups by state; no Ticket mutation route/UI was added。
+- Objective list continues to use filesystem read-through `/api/objectives`; no Objective mutation/API authority added。
+- Frontend remains static SPA/hash navigation; no SSR/business authority introduced。
+- Nix build succeeds with the new Rust source file。
+
+Non-blocking concerns:
+- `ObjectivesNavSection.svelte` only shows the “All objectives” sidebar link when objectives are successfully loaded and non-empty. In an empty/error state, the page is still reachable from hero links, but the sidebar itself does not provide a stable top-level Objectives link. Consider keeping `#/objectives` visible in all non-loading states in a follow-up。
+- Remote sanitization removes URL-scheme userinfo, but does not attempt query-param or SCP-like token redaction. Acceptable for the initial bounded summary, but worth tightening if remote URLs may include local secret-bearing config。
+
+Reviewer validation:
+- `cargo fmt --check`: passed
+- `git diff --check 0f7e78c1..HEAD`: passed
+- `cargo test -p yoi-workspace-server`: passed (`8 passed`)
+- `cargo check -p yoi-workspace-server`: passed
+- `cd web/workspace && deno task check`: passed (`svelte-check found 0 errors and 0 warnings`)
+- `cd web/workspace && deno task build`: passed
+- `cargo run -p yoi -- ticket doctor`: passed (`doctor: ok`)
+- `nix build .#yoi --no-link`: passed
+
+Generated artifacts:
+- Reviewer did not clean generated ignored artifacts after validation。
+- Ignored generated artifacts present:
+  - `target/`
+  - `web/workspace/.svelte-kit/`
+  - `web/workspace/build/`
+  - `web/workspace/node_modules/`
+- No untracked non-ignored files。
+
+Worktree status:
+- Clean tracked/non-ignored state on `impl/00001KVNGJPRG-repository-objective-pages` at `ceb1ee3b`。

+Workspace web に Repository / Objective pages を追加し、Orchestrator worktree の `orchestration` branch に統合した。

+- Read-only Repository backend APIs を追加:
+  - `/api/repositories`
+  - `/api/repositories/local`
+  - `/api/repositories/local/log`
+  - `/api/repositories/local/tickets`
+- Current workspace root を local Repository として扱う bounded repository summary を追加。
+- Git repository では bounded branch/head/root/dirty/remote/recent log summary を返す。
+- Non-Git workspace では `git.status = unavailable` と bounded diagnostics に degrade。
+- Git log summary は recent commit hash/subject/author/timestamp に限定し、diff/patch/file content/blame/config は読まない。
+- Remote URL summary は URL-scheme userinfo を redact。
+- Read-only Ticket Kanban を Ticket state ごとに grouping し、workspace-local Ticket fallback diagnostic を含めた。
+- Objective list summaries を filesystem Objective records から追加。
+- Static SPA に hash-navigation Repository / Objectives pages を追加。
+- Sidebar Repository/Objectives links を新 pages に接続。
+- Repository page に summary, Git summary/log, diagnostics, read-only Ticket Kanban を表示。
+- Objective page に title/state/updated_at/summary と detail placeholder links を表示。
+- Ticket / Objective canonical authority remains filesystem read-through records; mutation API / DB canonical migration は追加していない。
+
+統合・検証:
+- Merge commit: `7ee702b1 merge: repository objective pages`
+- Implementation commit: `ceb1ee3b feat: add repository objective pages`
+- Reviewer final verdict: approve
+- Validation passed: `cargo fmt --check`, `git diff --check HEAD^1..HEAD`, `cargo test -p yoi-workspace-server`, `cargo check -p yoi-workspace-server`, `deno task check`, `deno task build`, `cargo run -p yoi -- ticket doctor`, and `nix build .#yoi --no-link`。
+
+範囲外 / follow-up notes:
+- Repository CRUD/API, Objective edit/detail mutation, full Git browser/diff/file views, drag/drop Kanban, and write APIs were not implemented。
+- Reviewer noted possible follow-ups: keep `#/objectives` sidebar link visible even on objective empty/error states, and further tighten remote URL sanitization for query-param or SCP-like token forms if needed。

+## Implementation report
+
+Reviewer r1 approvalを受けて、実装ブランチを Orchestrator worktree の `orchestration` branch に統合した。
+
+統合:
+- Merge commit: `7ee702b1 merge: repository objective pages`
+- Merged branch: `impl/00001KVNGJPRG-repository-objective-pages`
+- Implementation commit:
+  - `ceb1ee3b feat: add repository objective pages`
+
+Orchestrator worktree validation:
+- `cargo fmt --check`: passed
+- `git diff --check HEAD^1..HEAD`: passed
+- `cargo test -p yoi-workspace-server`: passed (`8 passed`)
+- `cargo check -p yoi-workspace-server`: passed
+- `cd web/workspace && rm -rf node_modules .svelte-kit build && deno task check`: passed (`svelte-check found 0 errors and 0 warnings`)
+- `cd web/workspace && deno task build`: passed
+- `cargo run -p yoi -- ticket doctor`: passed (`doctor: ok`)
+- `nix build .#yoi --no-link`: passed
+
+Validation generated ignored frontend artifacts in Orchestrator worktree:
+- `web/workspace/node_modules/`
+- `web/workspace/.svelte-kit/`
+- `web/workspace/build/`
+
+These were removed after validation. Final Orchestrator worktree status after validation cleanup is clean on `orchestration` at `7ee702b1`。
