## 作成 LocalTicketBackend によって作成されました。 --- ## Intake summary チャットビューの TUI で Markdown pipe table が読み取り可能に描画できない不具合を bug Ticket として整理した。対象 surface は通常の chat / conversation view に限定し、session history / Pod metadata / worker history / prompt context は変更しないことを invariant とした。通常の pipe table 表示、既存 Markdown/plain text の非退行、狭い terminal での安全な表示、関連テストまたは手動確認を受け入れ条件にしている。 --- ## State changed 要件・受け入れ条件・invariant・validation が揃っており、Orchestrator が implementation routing できる状態になった。 --- ## State changed Ticket を `workspace-panel` が queued にしました。 --- ## State changed Accepted queued implementation after reading the Ticket and current workspace state. This is a bounded TUI chat rendering bug fix and is independent of the active Ticket backend/orchestration-plan worktree, so it can proceed in a separate worktree without overlapping source surfaces beyond normal validation. --- ## Decision Routing decision: implementation_ready Reason: - The Ticket is scoped to the normal TUI chat/conversation view and has concrete acceptance criteria for pipe-table readability, non-regression, narrow terminal behavior, and tests/manual confirmation. - It explicitly excludes Pod/session/history/context changes and non-chat surfaces. - Current active implementation work is in Ticket backend/orchestration-plan tooling; this TUI rendering fix has low source-conflict risk and can proceed in a separate worktree. IntentPacket: Intent: - Make ordinary Markdown pipe tables in assistant chat messages readable in the TUI conversation view without changing persisted history or model context. Binding decisions / invariants: - Only display/rendering behavior should change; do not mutate Pod history, session logs, worker history, prompt context, or stored message text for rendering. - Target the normal chat/conversation view. Do not treat this as a Ticket panel, `yoi ticket show`, docs rendering, or WebFetch extraction feature. - Do not pursue full GitHub Flavored Markdown table compatibility unless it falls out naturally from a small implementation; ordinary pipe tables are the acceptance target. - Rendering must be robust: malformed or too-wide tables should not panic, drop message content, or break the surrounding message block. - Preserve existing behavior for non-table Markdown/plain text as much as possible. - Avoid broad rendering abstraction rewrites or new large parser dependencies unless investigation proves they are necessary; escalate first if so. Implementation latitude: - Coder may either add explicit table handling to the existing Markdown renderer or normalize table blocks into a readable plain-text fallback within the rendering layer. - Column width/alignment/wrapping can be pragmatic and constrained by the existing TUI line/wrap model. - Add unit/snapshot-like tests around the rendering function or a narrow test fixture for chat message rendering. If interactive manual verification is needed, include exact steps in the implementation report. Escalate if: - A large Markdown parser dependency or public rendering API redesign is needed. - The change requires touching broad TUI surfaces outside chat/conversation rendering. - Correctness would require changing stored message/history representation. Validation: - Focused TUI Markdown/chat rendering tests covering a simple pipe table and non-table regression. - Narrow-terminal/wrapping safety test if feasible. - Relevant `cargo test -p tui ...` target(s). - `cargo fmt --check`. - `git diff --check`. - `cargo check --workspace`. - `nix build .#yoi` before final completion because TUI/package behavior changes. --- ## Implementation report Implementation routing started. Worktree/branch: - Worktree: `.worktree/tui-chat-markdown-table-rendering` - Branch: `tui-chat-markdown-table-rendering` - Base/routing commit: `60609ec ticket: route tui markdown table rendering` Spawned sibling Coder Pod: - `coder-tui-chat-markdown-table-rendering` - Scope: non-recursive read on parent workspace root plus recursive write limited to the child worktree. Note: an unrelated Ticket record update (`tui-composer-history-persistence` ready state) and project known-issues/objective records were committed before routing so the main workspace was clean enough for implementation side effects. --- ## Implementation report Coder implementation completed and is ready for sibling review. Coder Pod: - `coder-tui-chat-markdown-table-rendering` - Commit: `f767ec7a5945aff588fe0b8ce224b30efe4c2a85 tui: render markdown pipe tables in chat` - Worktree status before review: clean branch `tui-chat-markdown-table-rendering` - Stopped after collecting output to reclaim delegated worktree scope. Implementation summary: - Adds `pulldown-cmark` table event handling to `crates/tui/src/markdown.rs`. - Enables `Options::ENABLE_TABLES` in the TUI chat Markdown renderer. - Converts ordinary Markdown pipe tables into readable monospace rows with box separators and alignment-aware padding. - Keeps changes in the rendering layer only; no Pod/session/history/context storage changes. - Adds focused tests for readable table rendering, malformed/ragged/wide safety, and non-table pipe text regression. Coder-reported validation: - `cargo test -p tui markdown -- --nocapture` -> 17 passed - `cargo fmt --check` -> OK - `git diff --check` -> OK - `cargo check --workspace` -> OK - `nix build .#yoi` -> OK --- ## Review: approve Approve. Review evidence: - Reviewed commit `f767ec7a5945aff588fe0b8ce224b30efe4c2a85` on branch `tui-chat-markdown-table-rendering`; the only changed source file is `crates/tui/src/markdown.rs`. - The change stays in the TUI Markdown rendering layer: it enables `pulldown_cmark::Options::ENABLE_TABLES` in the existing renderer and collects/renders table events into display-only `Line` output. I did not find changes to Pod history, session logs, worker history, prompt context, or stored message text. - The renderer is used by the normal assistant chat/conversation rendering path (`ui.rs`) and this commit does not touch Ticket panel, `yoi ticket show`, docs rendering, or WebFetch extraction surfaces. - Table rendering keeps cell text for ragged/extra-column rows, pads missing cells, computes display widths with `unicode-width`, and falls back to ordinary event handling for non-table Markdown. Tests cover simple tables, alignment, ragged/too-wide safety, malformed table fallback, and non-table pipe text. Validation run from the worktree: - `cargo test -p tui markdown -- --nocapture` passed. - `cargo fmt --check` passed. - `git diff --check f767ec7a5945aff588fe0b8ce224b30efe4c2a85^ f767ec7a5945aff588fe0b8ce224b30efe4c2a85` passed. - `cargo check --workspace` passed. - `nix build .#yoi` passed. No blocking issues found. --- ## Implementation report Merge-ready dossier for human/orchestrator approval.

Intent / invariant check: - Makes ordinary Markdown pipe tables readable in the normal TUI chat/conversation Markdown renderer. - Changes display/rendering behavior only. - Does not mutate Pod history, session logs, worker history, prompt context, or stored message text. - Does not expand scope to Ticket panel, `yoi ticket show`, docs rendering, or WebFetch extraction. - Does not add a new large Markdown dependency or broad TUI rendering abstraction rewrite. Implementation summary: - Enables `pulldown-cmark` `Options::ENABLE_TABLES` in `crates/tui/src/markdown.rs`. - Adds table event collection/rendering into readable monospace rows with separators and alignment-aware padding. - Keeps ragged/extra-column/wide table content visible and pads missing cells. - Adds focused tests for simple table rendering, ragged/wide safety, and non-table pipe text regression. Validation evidence: - Coder reported pass: - `cargo test -p tui markdown -- --nocapture` - `cargo fmt --check` - `git diff --check` - `cargo check --workspace` - `nix build .#yoi` - Reviewer independently ran and passed: - `cargo test -p tui markdown -- --nocapture` - `cargo fmt --check` - `git diff --check f767ec7a5945aff588fe0b8ce224b30efe4c2a85^ f767ec7a5945aff588fe0b8ce224b30efe4c2a85` - `cargo check --workspace` - `nix build .#yoi` Residual risks / notes: - This is intentionally a pragmatic table renderer, not a full GFM table compatibility project. - Final merge/close/cleanup is intentionally not performed here without explicit merge approval. --- ## State changed Ticket closed; workflow_state を done に設定しました。 --- ## 完了 Implemented, reviewed, merged, and validated. Summary: - Enabled Markdown table parsing in the existing TUI chat/conversation Markdown renderer. - Rendered ordinary pipe tables as readable monospace rows with separators and alignment-aware padding. - Kept the change in display/rendering code only; no Pod history, session logs, worker history, prompt context, or stored message text mutation. - Added focused tests for readable table rendering, ragged/wide table safety, and non-table pipe text regression.
