BACK-473/474/477 - Wiki system: web UI, install command, online editing (split 2/9 of #669)

[MrLesk]

Note

Maintainer-split slice 2/9 of #669. All commits are authored by @kuwork — I only rebased them onto current main and resolved conflicts. Merge with Rebase and merge to keep the per-task commits and original authorship.

Stack

Based on pr669/1-editor-paste (slice 1). Review only the commits unique to this PR. After the previous slice merges, restack with git rebase --onto main pr669/1-editor-paste pr669/2-wiki-core.

Tasks in this slice

BACK-473 — Wiki section in web UI with file tree navigation

• src/file-system/operations.ts: getWikiTree() (recursive walker skipping wiki_output/), readWikiPage() (containment-checked path resolution + frontmatter parsing)
• src/server/index.ts: GET /api/wiki/tree, GET /api/wiki/*
• src/web/components/WikiDetail.tsx: read-only markdown viewer; SideNavigation.tsx: collapsible wiki tree section
• New types WikiTreeNode, WikiPage

BACK-474 — backlog wiki install <agent> CLI command

• src/commands/wiki-install.ts: agent alias mapping (claude/codex/agents), symlink with copy fallback, --force, --dry-run
• scripts/embed-wiki-skill.ts + src/skills/embedded/llm-wiki-for-backlog.ts: build-time embedded skill for the compiled binary
• .codex/skills/llm-wiki-for-backlog/: canonical skill source (SKILL.md, usermanual-writing-guide.md, merge.py)

BACK-477 — Wiki online editing, file watching, folder creation, labels

• src/file-system/operations.ts: saveWikiPage(), createWikiPage(), createWikiFolder(), renameWikiItem()
• src/core/content-store.ts: createWikiWatcher() → WebSocket live refresh
• src/server/index.ts: PUT /api/wiki/*, POST /api/wiki, PATCH /api/wiki/*
• WikiDetail.tsx: edit/save/cancel lifecycle, labels via ChipInput; SideNavigation.tsx: per-folder action dropdowns

Plus four fix commits: symlink path comparison (CI), wiki SPA route fallback, wikilink format enforcement in skill tables, empty-folder expand arrows.

Notes

• Scope decision for this slice: it introduces an entire wiki subsystem (file ops, server routes, web UI, CLI command, embedded LLM skill, .codex/ skill source). The rest of the stack (TASK-4.1 - CLI: Task Creation Commands #3–Add subtask 6.1: add subtask for local CLI installation #9) partially builds on these files, so accept/reject this slice first.
• Task IDs in backlog/tasks/ were minted on the fork — re-mint before merge if taken.
• Validated at this tip: bun install --frozen-lockfile, bunx tsc --noEmit.

Original combined PR: #669.

Alex's Agent: Maintainer cleanup: closing this draft as an archived slice of #669.

This PR is still part of a stacked broad feature bundle and is outside the current project scope. We are not merging this stack.

For future work, please open or link an issue before submitting a PR so the scope can be agreed before implementation. If a small fix from this slice is still desired, please extract it into a fresh PR against main with one narrow, agreed scope and no dependency on the #669 stack.

Future PRs in this area should link an issue first, or open one before implementation so scope can be agreed.
