spec: define v1.1 — full vimwiki replacement (Phases 11–18)

v1.0 shipped parsing + highlighting + navigation; the gap-analysis vs
github.com/vimwiki/vimwiki shows nuwiki covers ~95% of the syntax but
0% of the daily-authoring command surface (≈40 :Vimwiki* commands and
≈60 keymaps), the diary, tags, link health, HTML export commands, and
multi-wiki. v1.1 closes that gap without architectural changes — every
new editing operation lands as an LSP executeCommand returning a
WorkspaceEdit, so nuwiki-core stays the single source of truth.

Spec additions:

- Status line: v1.0 shipped; v1.1 in design.
- §1: v1.1 scope summarised; multi-wiki moved out of "non-goals (v1.0)"
  and into v1.1.
- §10: 8 new phase rows (11–18) under a v1.1 divider.
  - 11 Tags, 12 Workspace edits + executeCommand, 13 List/table edit
    commands, 14 Link health + TOC/index generation, 15 Diary,
    16 HTML export commands, 17 Multi-wiki, 18 Editor glue v2.
- §11: 8 new pending decisions (P10–P17): command namespace, tag
  syntax, list-edit transport, multi-wiki config shape, folding
  mechanism, diary path scheme, v1.0 config back-compat, markdown
  syntax inclusion.
- §12: new top-level v1.1 plan with 12 subsections covering stability
  commitment, tags spec (AST + index), workspace-edit semantics,
  ~15 nuwiki.* edit commands, link-health diagnostics, diary path
  conventions + commands, HTML export commands + per-wiki options,
  multi-wiki schema, full editor-glue v2 (:Vimwiki* compatibility
  table, default keymaps, text objects, folding, insert-mode behaviour,
  health-check additions), updated user-config schema example,
  §9 syntax checklist additions (tags, hex colour, table alignment,
  multi-line lists), CI/CD notes.

v1.0 stability is preserved: AST + Visitor + LSP capabilities +
HtmlRenderer output + v1.0 config keys are all backward-compatible.

+
+## 12. v1.1 — Full vimwiki Replacement
+
+v1.0 shipped the parsing + highlighting + navigation foundation. A vimwiki
+user transitioning to nuwiki today gets accurate syntax recognition and
+modern LSP nav, but loses the dense interactive layer that makes vimwiki
+ergonomic for daily authoring: ≈40 `:Vimwiki*` commands, ≈60 keymaps, the
+diary, the tag system, link health, HTML export commands, and multi-wiki
+configuration.
+
+v1.1 closes that gap. The architecture is unchanged — every new editing
+operation lands as an LSP `executeCommand` returning a `WorkspaceEdit`, so
+the `nuwiki-core` AST stays the single source of truth and the editor glue
+stays pure wiring.
+
+### 12.1 Stability commitment
+
+v1.1 is additive. The following stay backward-compatible:
+
+- `nuwiki-core` public AST + Visitor (additions only; no field renames)
+- LSP capabilities advertised in v1.0
+- `Renderer` trait + `HtmlRenderer` default output shape
+- v1.0 user-config keys (`wiki_root`, `file_extension`, `syntax`, `log_level`)
+
+New AST nodes (e.g. `TagNode`) and new LSP capabilities are opt-in by
+inspection. The Visitor trait gains default-bodied `visit_*` methods for new
+node kinds so existing Visitor implementations don't break.
+
+### 12.2 Tags (Phase 11)
+
+#### Syntax
+
+Vimwiki tags are colon-delimited sequences of non-space characters:
+
+```
+:tag-one:tag-two:other-tag:
+```
+
+Placement rules (matching vimwiki):
+
+- On line 1 or 2 of a file → file-level tag
+- Within 2 lines after a `= Heading =` → header-level tag
+- Otherwise → standalone anchor at the source line
+
+#### AST additions
+
+```
+TagNode (block)
+  span:    Span
+  tags:    Vec<String>
+  scope:   TagScope          -- File | Heading(idx) | Standalone
+
+PageMetadata (extend)
+  tags:    Vec<String>       -- file-level tags, accumulated
+```
+
+`TagNode` slots into `BlockNode` as a new variant. The Visitor gains
+`visit_tag` (default-bodied).
+
+#### Indexing
+
+`WorkspaceIndex` extends `IndexedPage` with:
+
+```
+IndexedPage (extend)
+  tags:           Vec<TagInfo>
+
+TagInfo
+  name:    String
+  scope:   TagScope
+  span:    Span
+```
+
+Plus a `tags_by_name: HashMap<String, Vec<(Url, Span)>>` reverse map. The
+existing backlink machinery in §6 stays as-is.
+
+#### LSP behaviour
+
+- `tags-as-anchors` extends `textDocument/definition`: `[[Page#some-tag]]`
+  resolves to the tag's location in the target page (in addition to headings).
+- `workspace/symbol` results include tags (with `SymbolKind::PROPERTY` or a
+  custom kind).
+- New `executeCommand` operations: `nuwiki.tags.search`,
+  `nuwiki.tags.generateLinks(tag, ...)`, `nuwiki.tags.rebuild` (force re-index).
+
+### 12.3 Workspace edits + `executeCommand` (Phase 12)
+
+#### Capability
+
+```
+ServerCapabilities {
+  execute_command_provider: Some(ExecuteCommandOptions {
+    commands: vec!["nuwiki.*", …],
+  }),
+  rename_provider: Some(true),
+  workspace: Some(WorkspaceServerCapabilities {
+    file_operations: Some(FileOperationOptions {
+      will_rename: Some(...),
+      did_rename: Some(...),
+      will_delete: Some(...),
+      did_delete: Some(...),
+    }),
+  }),
+}
+```
+
+#### `workspace/rename` semantics
+
+When a user renames `Page A` → `Page B`:
+
+1. Server emits a `WorkspaceEdit` containing a `RenameFile` op (`A.wiki` →
+   `B.wiki`).
+2. For every page in the index that links to `A`, the edit also rewrites
+   `[[A]]` → `[[B]]` (preserving description, anchor, kind).
+3. Anchors don't trigger renames — `[[A#anchor]]` follows.
+
+#### Custom commands router
+
+A single `executeCommand` handler dispatches by command name. Every command
+takes either:
+
+```
+{ uri: Url, position?: Position, range?: Range, ...args }
+```
+
+and returns a `WorkspaceEdit` (which the client applies via
+`workspace/applyEdit`).
+
+### 12.4 List & table editing commands (Phase 13)
+
+| Command | Operates on | Result |
+|---|---|---|
+| `nuwiki.list.toggleCheckbox` | list item under cursor | `[ ]` ↔ `[X]`, propagates parent state |
+| `nuwiki.list.cycleCheckbox` | list item | `[ ]` → `[.]` → `[o]` → `[O]` → `[X]` cycle |
+| `nuwiki.list.rejectCheckbox` | list item | toggle `[-]` rejected state |
+| `nuwiki.list.changeSymbol` | list item, args: `symbol: ListSymbol`, `whole_list: bool` | rewrite marker, renumber if numeric |
+| `nuwiki.list.changeLevel` | list item, args: `delta: i32`, `whole_subtree: bool` | re-indent + adjust child levels |
+| `nuwiki.list.renumber` | list, args: `whole_file: bool` | re-sequence numeric markers |
+| `nuwiki.list.removeDone` | range or current list | remove every `[X]` / `[-]` item and its checked children |
+| `nuwiki.list.nextTask` | document | navigate to next unfinished task (returns `Location`, not edit) |
+| `nuwiki.table.align` | table under cursor | reformat columns to max width |
+| `nuwiki.table.moveColumn` | cell, args: `dir: "left"\|"right"` | swap column with neighbour |
+| `nuwiki.table.insert` | cursor, args: `cols, rows` | insert blank table at cursor |
+| `nuwiki.heading.addLevel` | heading | promote (`==` → `===`) |
+| `nuwiki.heading.removeLevel` | heading | demote |
+| `nuwiki.link.normalize` | word/selection | convert to `[[wikilink]]`, add description if missing |
+| `nuwiki.link.pasteWikilink` | cursor | paste current page name as an absolute wikilink |
+| `nuwiki.link.pasteUrl` | cursor | paste the corresponding HTML output URL |
+| `nuwiki.colorize` | range, args: `color: String` | wrap in colour tag per `color_tag_template` |
+
+All operations resolve to a textual diff over the existing source so the
+AST stays the source of truth. None of them rely on editor-side state.
+
+### 12.5 Link health + TOC/index generation (Phase 14)
+
+#### Broken-link diagnostics
+
+A new diagnostic source `nuwiki.link` runs after each parse:
+
+- Wiki target → not in `WorkspaceIndex` → severity from config (default
+  `Warning`)
+- Anchor target → page exists but anchor doesn't → `Warning`
+- `file:` / `local:` → file exists on disk → `Warning` if missing
+- Raw URL / external → never diagnosed (we don't fetch)
+- Configurable filtering via `diagnostic.link.severity` (`off|hint|warn|error`)
+
+#### Commands
+
+| Command | Behaviour |
+|---|---|
+| `nuwiki.toc.generate` | inserts a nested list of headings in the current page; replaces existing `%toc` placeholder if present |
+| `nuwiki.links.generate` | inserts a flat list of all wiki pages (vimwiki's `:VimwikiGenerateLinks`) |
+| `nuwiki.workspace.checkLinks` | returns a `Vec<BrokenLink>` for the client to render in a quickfix-style view; also emits diagnostics |
+| `nuwiki.workspace.findOrphans` | returns pages with no incoming links |
+
+### 12.6 Diary (Phase 15)
+
+#### Path conventions
+
+```
+<wiki_root>/<diary_rel_path>/         # default: "diary"
+  diary.wiki                          # configurable: diary_index
+  2026-05-11.wiki                     # daily: YYYY-MM-DD
+  2026-W19.wiki                       # weekly: YYYY-Www (configurable)
+  2026-05.wiki                        # monthly
+  2026.wiki                           # yearly
+```
+
+#### Custom commands
+
+| Command | Behaviour |
+|---|---|
+| `nuwiki.diary.openToday` | open / create today's diary page |
+| `nuwiki.diary.openYesterday` | analogous |
+| `nuwiki.diary.openTomorrow` | analogous |
+| `nuwiki.diary.openIndex` | open the diary index page |
+| `nuwiki.diary.generateIndex` | rebuild the diary index page with current entries grouped by year/month |
+| `nuwiki.diary.next` | navigate to the chronologically next diary entry from the current one |
+| `nuwiki.diary.prev` | analogous |
+
+#### Calendar hook
+
+External plugins (Calendar.vim, neorg-style calendars) can query:
+
+- `nuwiki.diary.listEntries(year, month)` → list of dates with entries
+- `nuwiki.diary.openForDate(date)` → opens that date's entry
+
+These are `executeCommand` operations, not LSP standard methods.
+
+### 12.7 HTML export commands (Phase 16)
+
+The `HtmlRenderer` from Phase 5 stays as the engine. v1.1 wraps it in
+user-facing commands and the per-wiki HTML lifecycle.
+
+#### Per-wiki HTML options
+
+| Key | Default | Description |
+|---|---|---|
+| `html_path` | `<wiki_root>/_html` | output directory |
+| `template_path` | `<wiki_root>/_templates` | template lookup root |
+| `template_default` | `default` | base template name |
+| `template_ext` | `.tpl` | template extension |
+| `template_date_format` | `%Y-%m-%d` | format passed to `{{date}}` |
+| `css_name` | `style.css` | CSS file copied/created at export |
+| `auto_export` | `false` | export on save |
+| `html_filename_parameterization` | `false` | URL-safe slugs in output filenames |
+| `exclude_files` | `[]` | globs to skip |
+
+#### Commands
+
+| Command | Behaviour |
+|---|---|
+| `nuwiki.export.currentToHtml` | render current page; honours `%template`, copies CSS if missing |
+| `nuwiki.export.allToHtml` | export every page in the wiki |
+| `nuwiki.export.allToHtmlForce` | `:VimwikiAll2HTML!` equivalent |
+| `nuwiki.export.browse` | export current + open default browser to result |
+| `nuwiki.export.rss` | emit `rss.xml` of recent diary entries (when diary enabled) |
+
+#### Template variables
+
+The `HtmlRenderer` template substitution gains:
+
+- `{{title}}` (already shipped)
+- `{{content}}` (already shipped)
+- `{{date}}` (formatted via `template_date_format`)
+- `{{root_path}}` (relative path from output to `html_path` — for stylesheet
+  hrefs in nested pages)
+- `{{toc}}` (rendered TOC for current page)
+
+### 12.8 Multi-wiki (Phase 17)
+
+#### Config shape
+
+```lua
+require('nuwiki').setup({
+  wikis = {
+    {
+      name           = 'personal',
+      root           = '~/vimwiki',
+      file_extension = '.wiki',
+      syntax         = 'vimwiki',
+      diary_rel_path = 'diary',
+      html_path      = '~/vimwiki/_html',
+      -- … any per-wiki option
+    },
+    {
+      name           = 'work',
+      root           = '~/work-notes',
+      syntax         = 'vimwiki',
+    },
+  },
+  log_level = 'warn',
+})
+```
+
+The v1.0 single-wiki shape continues to work; internally it desugars to
+`wikis = [{ root = wiki_root, file_extension = file_extension, syntax = syntax }]`.
+
+#### Per-wiki context
+
+`WorkspaceIndex` becomes one per wiki. Backend holds:
+
+```
+indexes: Arc<DashMap<WikiId, Arc<RwLock<WorkspaceIndex>>>>
+```
+
+URI → wiki resolution walks the URI's filesystem path upward, matching
+against each registered root. Cross-wiki links (interwiki) resolve through
+the matching wiki's index.
+
+#### Custom commands
+
+| Command | Behaviour |
+|---|---|
+| `nuwiki.wiki.select` | client-side picker over `wikis`; resolves to a wiki id |
+| `nuwiki.wiki.openIndex` | open the selected wiki's `index.wiki` |
+| `nuwiki.wiki.tabOpenIndex` | open in new tab (client-side) |
+| `nuwiki.wiki.listAll` | returns the registered wikis for editor UIs |
+
+### 12.9 Editor glue v2 (Phase 18)
+
+The thickest user-facing layer. Per SPEC §6.3 it still contains no logic —
+every command body is a wrapper that issues `workspace/executeCommand`.
+
+#### `:Vimwiki*` command compatibility
+
+`ftplugin/nuwiki.vim` defines every command listed in §4 of vimwiki's help,
+mapped to the corresponding `executeCommand`:
+
+| Vimwiki command | nuwiki implementation |
+|---|---|
+| `:VimwikiIndex` `[count]` | `nuwiki.wiki.openIndex(count)` |
+| `:VimwikiTabIndex` | tab-open variant |
+| `:VimwikiUISelect` | `nuwiki.wiki.select` |
+| `:VimwikiDiaryIndex` | `nuwiki.diary.openIndex` |
+| `:VimwikiMakeDiaryNote` | `nuwiki.diary.openToday` |
+| `:VimwikiMakeYesterdayDiaryNote` | `nuwiki.diary.openYesterday` |
+| `:VimwikiMakeTomorrowDiaryNote` | `nuwiki.diary.openTomorrow` |
+| `:VimwikiFollowLink` | client `vim.lsp.buf.definition()` |
+| `:VimwikiGoBackLink` | client `<C-o>` (jumplist) |
+| `:VimwikiSplitLink` / `:VimwikiVSplitLink` | client-side `:split`/`:vsplit` + `definition` |
+| `:VimwikiTabnewLink` / `:VimwikiTabDropLink` | client-side `:tabnew` + `definition` |
+| `:VimwikiNextLink` / `:VimwikiPrevLink` | `nuwiki.cursor.nextLink` / `prevLink` |
+| `:VimwikiGoto {name}` | `nuwiki.wiki.gotoPage(name)` |
+| `:VimwikiDeleteFile` | server-side delete via `executeCommand` |
+| `:VimwikiRenameFile` | client prompt → `workspace/rename` |
+| `:VimwikiRemoveDone` | `nuwiki.list.removeDone` |
+| `:VimwikiNextTask` | `nuwiki.list.nextTask` |
+| `:Vimwiki2HTML` | `nuwiki.export.currentToHtml` |
+| `:Vimwiki2HTMLBrowse` | `nuwiki.export.browse` |
+| `:VimwikiAll2HTML[!]` | `nuwiki.export.allToHtml[Force]` |
+| `:VimwikiRss` | `nuwiki.export.rss` |
+| `:VimwikiToggleListItem` | `nuwiki.list.toggleCheckbox` |
+| `:VimwikiToggleRejectedListItem` | `nuwiki.list.rejectCheckbox` |
+| `:VimwikiListChangeLvl CMD` | `nuwiki.list.changeLevel` / `changeSymbol` |
+| `:VimwikiSearch` / `:VWS` | client `:lvimgrep` wrapper over wiki root |
+| `:VimwikiBacklinks` / `:VWB` | client `vim.lsp.buf.references()` |
+| `:VimwikiTable [cols] [rows]` | `nuwiki.table.insert` |
+| `:VimwikiTableMoveColumnLeft/Right` | `nuwiki.table.moveColumn` |
+| `:VimwikiGenerateLinks` | `nuwiki.links.generate` |
+| `:VimwikiDiaryGenerateLinks` | `nuwiki.diary.generateIndex` |
+| `:VimwikiDiaryNextDay` / `:VimwikiDiaryPrevDay` | `nuwiki.diary.next/prev` |
+| `:VimwikiTOC` | `nuwiki.toc.generate` |
+| `:VimwikiCheckLinks` | `nuwiki.workspace.checkLinks` |
+| `:VimwikiRebuildTags` | `nuwiki.tags.rebuild` |
+| `:VimwikiSearchTags {tag}` | `nuwiki.tags.search` |
+| `:VimwikiGenerateTagLinks` | `nuwiki.tags.generateLinks` |
+| `:VimwikiColorize {color}` | `nuwiki.colorize` |
+| `:VimwikiPasteLink` | `nuwiki.link.pasteWikilink` |
+| `:VimwikiPasteUrl` | `nuwiki.link.pasteUrl` |
+
+Each `:Vimwiki*` form ships with a matching `:Nuwiki*` alias (P10
+resolution).
+
+#### Default keymaps
+
+`g:nuwiki_key_mappings` (Vim) / `mappings = { … }` (Neovim) controls
+opt-in keymap registration. Default: enabled; group flags let users disable
+the table/list/heading/diary subsets independently.
+
+Buffer-local maps mirror vimwiki:
+
+- `<Leader>ww` / `<Leader>wt` / `<Leader>ws` / `<Leader>wi` /
+  `<Leader>w<Leader>w` etc. — wiki navigation
+- `<CR>` / `<S-CR>` / `<C-CR>` / `<M-CR>` / `<C-S-CR>` — link follow variants
+- `<Backspace>` / `<Tab>` / `<S-Tab>` — link history + per-page link navigation
+- `=` / `-` / `[[` / `]]` / `[=` / `]=` / `]u` / `[u` — header manipulation +
+  navigation (pure VimL/Lua, regex over current buffer — no LSP round-trip)
+- `+` — `nuwiki.link.normalize`
+- `<C-Space>` — `nuwiki.list.toggleCheckbox`
+- `gnt` — `nuwiki.list.nextTask`
+- `gl<Space>` / `gL<Space>` — checkbox remove (single / list)
+- `gln` / `glp` — checkbox cycle up/down
+- `gll` / `gLl` / `glh` / `gLh` — list level change (single / subtree)
+- `glr` / `gLr` — list renumber
+- `gl*` / `gl#` / `gl-` / `gl+` / `gl1` / `gla` / `glA` / `gli` / `glI` —
+  list symbol change (single / subtree variants `gL`*)
+- `glx` — `:VimwikiToggleRejectedListItem`
+- `gqq` / `gww` / `gq1` / `gw1` — table align
+- `<A-Left>` / `<A-Right>` — table move column
+- `<C-Up>` / `<C-Down>` — diary prev/next day
+- `<Leader>wh` / `<Leader>whh` — HTML export current / browse
+- `<Leader>wc` — colorize (asks for colour)
+- `<Leader>wn` — goto/create new page
+- `<Leader>wd` / `<Leader>wr` — delete / rename current page
+- Mouse: `<2-LeftMouse>`, `<S-2-LeftMouse>`, `<C-2-LeftMouse>`,
+  `<RightMouse><LeftMouse>` (opt-in via `g:nuwiki_mouse_mappings`)
+
+#### Insert-mode behaviour

+- Table cells: `<CR>`/`<Tab>`/`<S-Tab>` navigate cells, create rows
+  on overflow; implemented in Lua/VimL via a small autocmd
+- Lists: `<CR>` inserts the next bullet/number; `<S-CR>` continues without
+  a new bullet; `<C-T>`/`<C-D>` indent/dedent; `<C-L><C-J>`/`<C-L><C-K>`
+  cycle the list symbol; `<C-L><C-M>` toggles a list item on/off
+- All gated by `b:did_ftplugin` and remappable
+
+#### Text objects
+
+`omap`/`xmap` defining:
+
+| Object | Selects |
+|---|---|
+| `ah` / `ih` | a header (with/without trailing blank lines + header line itself) |
+| `aH` / `iH` | a header + all sub-headers ([count] climbs parent levels) |
+| `a\` / `i\` | a table cell |
+| `ac` / `ic` | a table column |
+| `al` / `il` | a list item (with/without children) |
+
+Pure VimL/Lua — no LSP round-trip. Reuses our AST-shaped regexes.
+
+#### Folding
+
+Per P14 resolution; the spec'd default (subject to that decision):
+
+- `setlocal foldmethod=expr` + `foldexpr=NuwikiFold(v:lnum)` (or LSP
+  `foldingRange` driving it on Neovim 0.11+)
+- Folds at heading boundaries; nested headings nest folds
+- List-item folds when configured via `g:nuwiki_folding = 'list'`
+- Custom variant via `g:nuwiki_folding = 'custom'`
+
+#### Health check additions
+
+`:checkhealth nuwiki` v1.1 reports:
+
+- LSP commands registered (per command name)
+- Index loaded for each registered wiki
+- Tags table built
+- HTML output path writable
+- Default keymaps installed (or disabled by config)

+### 12.11 Updated §9 syntax checklist (additions)
+
+The following items extend the v1.0 checklist:
+
+#### Tags
+- [ ] Inline tag sequence: `:tag-one:tag-two:`
+- [ ] File-level tag (line 1–2 of a wiki page)
+- [ ] Header-level tag (within 2 lines after a heading)
+- [ ] Tag-as-anchor target (`[[Page#some-tag]]`)
+- [ ] Hex-colour code rendering in code blocks (`` `#ffe119` ``)
+
+#### Tables (additions)
+- [ ] Column-alignment markers in header separator: `|:--|` / `|:--:|` / `|--:|`
+
+#### Lists (parser extensions)
+- [ ] Multi-line list item (indented continuation lines)
+- [ ] Mixed-symbol lists at the same level
+
+### 12.12 Updated CI/CD
+
+No new workflow files. The existing `ci.yaml` continues to gate
+`fmt`/`clippy`/`test`. New phases land behind feature additions in the
+existing crates; the test suite grows accordingly.
