+## ⚠️ MANDATORY: macOS Bundle Build Order and Blogmark Verification
+
+**`mix release` copies `priv/static` as-is — it never rebuilds assets.** Always build in this order, or the bundle ships stale JS while the server code is current (this silently broke blogmark deep links in July 2026: the server waited for the client's `shell_ready` event that the stale `app.js` never sent, so every deep link queued forever with no error, no toast, no log):
+
+```
+mix assets.deploy
+MIX_ENV=prod mix release bds --overwrite
+mix bds.bundle.macos
+```
+
+**After building a bundle, verify blogmark deep links end-to-end with:**
+
+```
+scripts/verify_blogmark_macos.sh [path/to/BDS2.app]   # defaults to dist/macos/BDS2.app
+```
+
+The script launches the bundle via LaunchServices with an isolated database (`launchctl setenv BDS_DATABASE_PATH ...`), fires `bds2://new-post` links with `open -a` exactly like a browser bookmarklet, and asserts draft posts appear in the database — both for cold start (link launches the app, queued until the shell attaches) and for an already-running app. It refuses to run while any BDS2 instance is up; quit the app first.
+
+Things learned the hard way, encoded in the script — do not "simplify" them away:
+
+- Deep links only reach an app **launched through LaunchServices** (`open -a`). A process started by exec'ing `Contents/MacOS/bds2` from a shell never receives Apple Events, so deep links vanish without a trace. For the same reason `open` does not inherit the shell environment — inject env vars with `launchctl setenv` (and unset them afterwards).
+- To introspect a running bundle, launch it with `RELEASE_DISTRIBUTION=name` and `RELEASE_NODE=bds@127.0.0.1` set (via `launchctl setenv`), then use `.../Contents/Resources/rel/bin/bds rpc '<elixir>'` with the same env. The default `-sname` node is unreachable when the hostname resolves to LAN addresses.
+- The wx → `Desktop.Env` → `BDS.Desktop.DeepLink` → shell pipeline downstream of the OS can be exercised without LaunchServices via `send(Process.whereis(BDS.Desktop.DeepLink), {:open_url, ~c"bds2://new-post?..."})` over rpc.

+## Running a headless server and the terminal UI
+
+bDS2 can run without a window on a server (for example a Linux VPS) and be used from several places at once. Start it with `BDS_MODE=server`; the same release binary that runs the desktop app then runs headless. All clients connect through one SSH port (default 2222) — the web endpoint itself stays private on the server.
+
+Access is controlled by SSH keys, not passwords. On first start the server creates an `ssh/` folder next to its database (for example `~/Library/Application Support/BDS2/ssh/` on macOS) containing the host key and an empty `authorized_keys` file. Paste the public keys of every machine that may connect into `authorized_keys`, one per line — the same file format OpenSSH uses.
+
+To work in a terminal, connect with plain `ssh -p 2222 user@server`: the terminal UI opens directly. You can browse posts, media, templates, scripts, and tags, create and edit posts, publish, preview images, and run the one-shot AI actions. The status line at the bottom always shows the available keys.
+
+To work in the desktop app against a remote server, use **File → Connect to Server…** and enter `user@host` (or `user@host:port`). The app connects with the SSH key from its own local `ssh/` folder and shows the remote workspace in the window; **File → Disconnect from Server** returns to the local workspace. A plain browser works too, through a manual SSH tunnel (`ssh -p 2222 -L 4010:127.0.0.1:4010 user@server`, then open `http://127.0.0.1:4010`).
+
+Everything you see stays synchronized: when a script, another client, or a pipeline changes content on the server, every connected terminal and window updates. The interface language is a server-side setting — changing it in any client changes it for all of them.
+
+### Key takeaways
+
+- `BDS_MODE=server` runs the same app headless; only the SSH port is exposed.
+- Access is public-key only: manage `authorized_keys` in the server's `ssh/` folder.
+- `ssh` gives the terminal UI; **File → Connect to Server…** gives the desktop app; both use the same keys.
+- All connected clients stay synchronized and share one interface language.

+## Headless Server Mode And Terminal UI
+
+Since issue #26 the app has three boot modes, selected with the `BDS_MODE`
+environment variable (any release or dev boot; default is the desktop app):
+
+- `desktop` — the native desktop app, unchanged.
+- `server` — headless: no window, loopback-only HTTP endpoint, CLI sync
+  watcher, and an SSH daemon serving the terminal UI. Works on macOS,
+  Windows, and Linux (no display needed).
+- `tui` — the headless server plus a TUI attached to the launching terminal.
+
+### Build and run a headless server
+
+```bash
+MIX_ENV=prod mix release bds --overwrite
+BDS_MODE=server _build/prod/rel/bds/bin/bds start
+```
+
+The SSH daemon listens on port `2222` (`BDS_SSH_PORT` or
+`config :bds, :server, ssh_port:` to change). Authentication is public-key
+only: on first boot the server generates a host key and an empty
+`authorized_keys` (mode 600) in `ssh/` next to the database (default
+`~/Library/Application Support/BDS2/ssh/`, or under `BDS_DATABASE_PATH`).
+Add your public key there, then connect from any terminal:
+
+```bash
+ssh -p 2222 <server-host>          # opens the TUI
+```
+
+Each SSH connection gets its own TUI session on the server; only terminal
+cells cross the wire. All clients stay synchronized through the domain
+event bus (`BDS.Events`) — a post created by a pipeline or another client
+appears in every open shell.
+
+### TUI keys
+
+`↑/↓` or `j/k` navigate · `enter` open · `n` new post · `1-5` switch view
+(posts/media/templates/scripts/tags) · `:` command prompt (metadata
+diff, validate site, force render, rebuilds, …; `:?` lists all) ·
+metadata-diff/site-validation reports open as panels — `enter` applies
+the whole report (repair from files / incremental apply), `esc` cancels ·
+`r` refresh · in the editor:
+`ctrl+s` save, `ctrl+p` publish, `ctrl+e` word-wrapped preview,
+`ctrl+t` title, `ctrl+l` language, `ctrl+g` AI suggestions
+(airplane-mode gated), `esc` back · `ctrl+q` quit.
+Images preview inline via the terminal image protocol. The UI language is
+the server-side setting shared by every client.
+
+### Remote GUI
+
+The HTTP endpoint stays bound to `127.0.0.1` and is never exposed; GUI
+clients tunnel through the same SSH daemon and keys:
+
+```bash
+ssh -p 2222 -L 4010:127.0.0.1:4010 -N <server-host> &
+open http://127.0.0.1:4010
+```
+
+Or use the desktop app directly: **File → Connect to Server…** takes
+`user@host[:port]`, connects with the client key from the same local
+`ssh/` directory (public-key auth, trust-on-first-use `known_hosts`),
+tunnels to the server, and points the window at it. **File → Disconnect
+from Server** returns to the local workspace.
+
+## Monaco Editor
+
+Monaco is bundled via esbuild using its ESM entry point (`monaco-editor/esm/vs/editor/editor.main.js`). The
+main bundle is built as part of `mix assets.build` and lives at `priv/static/assets/monaco.js` and
+`monaco.css`; ESM worker bundles live under `priv/static/assets/monaco/`.
+
+```bash
+mix monaco.version    # show current monaco-editor version
+mix monaco.update 0.55.1  # update to a specific version and rebuild the bundle
+```
+
+The update task runs `npm install monaco-editor@<version>`, cleans the old bundle, and rebuilds via esbuild.
+See https://www.npmjs.com/package/monaco-editor for available versions.

-| A1-14b | ~~USearch HNSW ANN index + debounced persistence not implemented~~ | embedding.allium config/FindSimilar/DebouncedPersistence | `Embeddings.Index` is now an HNSW (hnswlib) ANN index with debounced persistence | **Resolved:** rewrote `Embeddings.Index` as a DB-free GenServer wrapping an hnswlib HNSW graph (cosine, M=16, efConstruction=128, efSearch=64) — O(n·log n) build, O(log n) queries, replacing the O(n²) JSON cosine snapshot; per-project in-memory index + `label→post_id` map; 5s debounced `save_index` + `.meta.json` sidecar, force-save on project switch (`set_active_project`) and shutdown (`terminate`), `forget/1` on project delete; lazy reload from disk with rebuild-from-DB self-heal on miss; `find_similar`/`find_duplicates`/`compute_similarities` rewired (no brute-force fallback); USearch has no Elixir binding so hnswlib provides the identical HNSW algorithm/params (spec reconciled); supervision + dialyzer PLT updated; tests updated for debounced/binary persistence + self-heal. Follow-up hardening: explicit rebuild now forces re-embedding regardless of content_hash (ReindexAll), and model-unavailable errors propagate cleanly (post saves degrade to unindexed + log; rebuild/index return `{:error, reason}` surfaced as a failed task with a user-facing message instead of crashing). |
-| A1-14c | ~~Embedding model runs on CPU only; no Apple GPU acceleration~~ | embedding.allium invariant NativeAcceleratedExecution | `Backends.Neural` now selects the defn compiler at serving-build time: Apple GPU via EMLX (MLX/Metal) on arm64 macOS, EXLA-CPU elsewhere | **Resolved:** added `{:emlx, "~> 0.2.0"}` dep (ships precompiled MLX binaries; EMLX 0.2.0 implements both `EMLX.Backend` and the `Nx.Defn.Compiler` behaviour, GPU-default); `Backends.Neural` gained a pure `select_accelerator/3` policy (`:auto` prefers EMLX only when available **and** on Apple Silicon; explicit `:emlx`/`:exla` honoured; forced `:emlx` degrades to EXLA when unavailable so misconfigured hosts still run), `current_accelerator/0`, and `defn_options/1`; `build_serving` places params on `{EMLX.Backend, device: :gpu}` and compiles with `EMLX` for the EMLX path, keeps `EXLA` otherwise; new `accelerator: :auto` config key; spec `NativeAcceleratedExecution` + `EmbeddingModel` updated; PLT app added; 7 tests added (offline — test config still uses the InApp stub). |
-| A1-15 | ~~Preview vs generation content source strategy undocumented~~ | preview.allium (no invariant), generation.allium (no invariant) | Generation uses only published .md file content (`Generation.Data` snapshots set `content: nil`); preview includes published+draft posts and prefers DB content over file (`Preview.Router` queries `:published`/`:draft`, uses `editor_body`) | **Resolved:** added `PreviewDraftOverlay` invariant to preview.allium and `GenerationPublishedOnly` invariant to generation.allium; both cross-reference each other; code already correct, 3 tests added for draft-in-preview behavior |
-| A1-16 | ~~Public project content + data_path discovery not compliant with storage-location spec~~ | project.allium `PublicContentLivesInProjectFolder` / `PrivateArtifactsLiveInOsAppDir` / `DataPathNotPersistedInProjectJson` / `DiscoverProjectDataPath` | Public content now lives under a per-user default content location, never the repo | **Resolved:** `project_data_dir/1` drops the `priv/data/projects/<id>` repo fallback — a project without an explicit `data_path` resolves to `default_content_root()/<id>` (configurable via `:default_content_root`, else `~/bds`), never the repo or `private_dir`; the `default` project is now created on first launch with an explicit `data_path` under that location and its folder is `mkdir`'d (`PublicContentLivesInProjectFolder`); added `Projects.private_dir/0`, `default_content_root/0`, and a machine-local project registry (`registry_path/0` → `project_registry.json` under `private_dir`, written on create/ensure-default, removed on delete) that remembers each project's folder without embedding it in `meta/project.json` (`DataPathNotPersistedInProjectJson`/`DiscoverProjectDataPath` — already satisfied since `project.json` never serializes `data_path`); `delete_project` removes app-managed folders (those under `default_content_root`) but preserves user-chosen external folders; committed `priv/data/projects/default/` content removed from the repo and `/priv/data/projects/` git-ignored; test config redirects `:default_content_root` to a temp dir; 4 tests added (default folder outside repo/private, no-repo fallback, registry round-trip, registry cleanup on delete). |
-| A1-17 | ~~`bds2://new-post` blogmark deep link is never received or routed~~ | script.allium:74 (`BlogmarkReceived`), script.allium:233-268 (`ExecuteTransform`/`TransformTrigger`), editor_settings.allium:141-143 (`BookmarkletCopy`) | `BDS.Desktop.DeepLink` subscribes to OS `{:open_url, ...}` events and routes `bds2://` links to the shell; `BDS.Blogmark` parses + runs transforms + creates the draft; `ShellLive` opens it and surfaces toasts | **Resolved:** added `BDS.Blogmark.parse_deep_link/1` (parses `bds2://new-post?title=&url=&content=&tags=&categories=` into a `{title, content?, tags, categories, url}` candidate, rejecting unsupported scheme/action) and `receive_deep_link/3` (runs `BDS.Scripts.Transforms.run/3` then creates a draft post, defaulting categories from `blogmark_category` only when neither the link nor a transform set one); `BDS.Desktop.DeepLink` GenServer subscribes to `Desktop.Env` `{:open_url, [url]}` events and broadcasts `{:blogmark_deep_link, url}` over PubSub (added to the desktop supervision tree, guarded for headless/test); `ShellLive.handle_info({:blogmark_deep_link, url})` runs the import against the active project, opens the new post tab (route `"post"`), and appends transform toasts/errors to the output panel (warns when no project is open). OS-level scheme registration (macOS `CFBundleURLTypes` in the packaged `Info.plist`) is documented in `BDS.Desktop.DeepLink` — no app-bundle pipeline exists in the repo yet. i18n added for `Blogmark`/"Open a project before importing a blogmark." (de/fr/it/es); 13 tests added (5 parse, 5 receive incl. transforms + default category, 3 deep-link routing, 1 shell create+open). |

-| ID | Gap | Spec | Code | Path |
-|---|---|---|---|---|
-| A2-1 | ~~WYSIWYG/visual editor mode (3 modes)~~ | editor_post.allium:159-164 | Only markdown+preview; visual normalizes to markdown | **Resolved:** spec updated to 2 modes (markdown/preview), visual/WYSIWYG dropped |

-| A2-10 | ~~Panel tabs: problems, terminal~~ | layout.allium:235-240 | `[:tasks, :output, :post_links, :git_log]` | **Resolved:** spec already lists tasks/output/post_links/git_log with availability and fallback rules matching code |
-| A2-11 | ~~Git sidebar: commit input, history, push/pull~~ | sidebar_views.allium | Only "Working tree" item | **Moved to A1-13:** backend code exists in BDS.Git, sidebar must wire it up |
-| A2-12 | ~~Slug timestamp fallback after 999~~ | post.allium:21 | Unbounded numeric suffix | **Resolved:** spec updated — uniqueness comment now says unbounded numeric suffix, no 999 cap or timestamp fallback |
-| A2-13 | ~~Thumbnail generation is async~~ | engine_side_effects.allium:117 | Synchronous | **Resolved:** spec updated — import thumbnail generation now says synchronous (awaited, logged on error), matching code; summary table changed from `async` to `sync` |
-| A2-14 | ~~AiModelModality: :video vs :file/:tool~~ | schema.allium:291 | Code has `:file`, `:tool` instead of `:video` | **Resolved:** spec updated — modality enum now lists "text" \| "image" \| "audio" \| "file" \| "tool", matching code |
-| A2-15 | ~~JSON key convention: snake_case vs camelCase~~ | frontmatter.allium values | Code uses camelCase for all metadata JSON | **Resolved:** all value types in frontmatter.allium updated to camelCase field names; added CamelCaseKeys invariant; surfaces updated; also added linkedPostIds to MediaSidecar (C-2) and projectId to TemplateFrontmatter/ScriptFrontmatter (B1-9) |
-| A2-16 | ~~Snowball stemmer language list~~ | search.allium:26-31 | Library determines which have algorithms vs passthrough | **Resolved:** spec updated — StemmerLanguage comment now says "Snowball stemmers via library (Stemex); languages with algorithm get real stemming, others pass through" |
-| A2-17 | ~~`provider_package_ref` on AiModel~~ | schema.allium:282 | Not in code; legacy field not needed | **Resolved:** dropped from AiModel entity and AiModelRecordSurface in schema.allium; DB column retained (migration artifact) |

-## B. Code Behavior Not in Spec
-
-### B1. Must Add to Spec (domain-level, affects behavior)
-
-| ID | Behavior | Code Location | Path |
-|---|---|---|---|
-| ~~B1-1~~ | ~~Chat inline surfaces (9 types: card, chart, form, list, metric, mindmap, table, tabs, text/json)~~ | `tool_surfaces.ex` | **Resolved:** added InlineSurface value type with all 9 discriminators, supporting value types (SurfaceAction, ChartSeries, MindmapNode, FormField, FieldOption, TabPanel), inline_surfaces on ChatMessage, InlineSurfaceRendering guarantee, and surface_form_debounce_ms config to editor_chat.allium; updated StructuredRenderTools invariant in ai.allium to list all 9 types |
-| ~~B1-2~~ | ~~Auto-translation system (AutoTranslation.maybe_schedule, media cascade, batch fill)~~ | `lib/bds/posts/auto_translation.ex` | **Resolved:** distilled into translation.allium — added `AutoTranslationControlSurface` (PostSavedForAutoTranslation reactive + FillMissingTranslationsRequested batch triggers), three rules (`ScheduleAutoTranslation` draft-per-missing-language + media cascade, `AutoTranslatePost` upsert/auto-publish primitive, `AutoTranslateMediaCascade` linked-media per-language tasks, `FillMissingTranslations` published-only batch emitting `ProgressReported` + `FillMissingTranslationsCompleted`), three invariants (`AutoTranslationGatedByEndpoint`, `AutoTranslationSkipsDoNotTranslate`, `AutoTranslationOnlyMissingLanguages`), and `auto_translation_task_group_name` config; `allium check` passes |
-| ~~B1-3~~ | ~~3 extra settings sections (Technology, MCP, Data Maintenance)~~ | `lib/bds/desktop/shell_live/settings_editor/` | **Resolved:** distilled into editor_settings.allium — added `SettingsTechnologySection` (semantic_similarity toggle + read-only scripting-runtime note, saved with project metadata), `SettingsDataSection` (rebuild_targets), and `technology_section`/`data_section` on `SettingsView`; reconciled `SettingsMCPSection`/`MCPAgentRow` to code (dropped non-existent status badge; added `is_supported`/`config_path`; only Claude Code + GitHub Copilot supported); updated TechnologySection/MCPSection/DataMaintenanceSection guarantees (7 rebuild buttons incl. Rebuild Embedding Index) and SettingsRebuild rule entity_type (+embedding); `allium check` passes |
-| ~~B1-4~~ | ~~Style/Theme as separate tab (`:style`), not settings section~~ | `lib/bds/desktop/shell_live/settings_editor/style_editor.ex` | **Resolved:** editor_settings.allium Style view section now frames it as its own `style` singleton tab (cross-ref tabs.allium), explicitly NOT a SettingsView collapsible section; added `SeparateTab` guarantee (requires active project), documented 20 named Pico themes and the theme display-name transform ("-"→" ", capitalise); `allium check` passes |
-| ~~B1-5~~ | ~~`published_*` snapshot fields on Post for diffing~~ | `lib/bds/posts/post.ex:61-65` | **Resolved:** added published_title/content/tags/categories/excerpt snapshot fields to the Post entity in post.allium, noting their role in changes_affect_published_content / ReopenPublishedPost (schema.allium already listed them) |
-| ~~B1-6~~ | ~~Full rendering subsystem (Liquex, Filters, Labels, LinksAndLanguages, PostRendering)~~ | `lib/bds/rendering/` | **Resolved:** new `rendering.allium` distills the shared render subsystem — 3 custom filters (i18n/markdown/slugify), markdown→HTML + URL rewriting, built-in `[[...]]` macros (youtube/vimeo/gallery/photo_archive/tag_cloud) with isolation invariant, links/languages (LinkContext, language prefix, backlinks), RenderLabels (content-language gettext + months), and post/list/not-found assign builders; added `SharedRenderPathForPreviewAndGeneration` invariant and wired into bds.allium |
-| ~~B1-7~~ | ~~404.html generation~~ | `lib/bds/generation/outputs.ex:344-345` | **Resolved:** added `FileGenerated("404.html")` (+ `{lang}/404.html` per blog language) to GenerateCoreSectionPages in generation.allium |
-| B1-8 | ~~`linkedPostIds` in media sidecar~~ | `lib/bds/media/sidecars.ex:42` | **Resolved:** added to MediaSidecar value in frontmatter.allium (with A2-15) |
-| B1-9 | ~~`projectId` in template/script frontmatter~~ | `templates.ex:337`, `scripts.ex:268` | **Resolved:** added projectId to TemplateFrontmatter and ScriptFrontmatter in frontmatter.allium (with A2-15) |
-| ~~B1-10~~ | ~~Media translation editing modal~~ | `media_editor.html.heex:275-303` | **Resolved:** editor_media.allium corrected — MediaTranslationEdit opens an "Edit Translation" modal (not inline); added `TranslationEditModal` guarantee (language hidden field + Title/Alt/Caption inputs, Cancel/Save footer) |
-| ~~B1-11~~ | ~~Menu editor drag-drop, indent/unindent/move~~ | `lib/bds/desktop/menu_editor/tree_ops.ex` | **Resolved:** already covered in editor_misc.allium — MenuMoveItem rule (up/down/indent/unindent), DragDrop + MoveDirections guarantees, HomeItemProtection (D1-18); verified against tree_ops.ex |
-| ~~B1-12~~ | ~~`:language_picker` overlay with flag emojis~~ | `shell_overlay.html.heex:116-139` | **Resolved:** already in modals.allium — LanguagePickerModal/LanguageTarget (flag emoji, name, existing-translation status badge); verified matches overlay code |
-| ~~B1-13~~ | ~~`:confirm_dialog` generic confirmation~~ | `shell_overlay.html.heex:171-187` | **Resolved:** already in modals.allium — ConfirmDialog (title/message, Cancel/Confirm); verified matches overlay code |
-| ~~B1-14~~ | ~~Publish actions for scripts and templates~~ | `script_editor.html.heex:10-12`, `template_editor.html.heex:10-12` | **Resolved:** added `can_publish` field, Publish button in HeaderLayout (shown only when draft), ScriptPublishRequested/TemplatePublishRequested surface events and ScriptPublish/TemplatePublish rules (validate-then-publish) to editor_script.allium + editor_template.allium |
-| ~~B1-15~~ | ~~`:import` as full editor tab~~ | `lib/bds/ui/import_editor.ex` | **Resolved:** already in tabs.allium (import singleton/pinned tab + editor route) and fully detailed as ImportAnalysisView in editor_misc.allium |
-| ~~B1-16~~ | ~~`:documentation`/`:api_documentation` tab types~~ | `lib/bds/desktop/misc_editor/` | **Resolved:** already in tabs.allium (both listed as singleton tabs + editor views: DOCUMENTATION.md / API.md) with DocumentationSurface in editor_misc.allium |
-| ~~B1-17~~ | ~~Metadata diff covers embedding, media_translation, post_translation as entity types~~ | `lib/bds/maintenance/repair.ex` | **Resolved:** metadata_diff.allium DiffReport entity_type list expanded to all 7 types; RunMetadataDiff notes media/media_translation/script/template/embedding (content_hash) coverage; added `RepairMetadataDiffItem` rule + surface event documenting the file_to_db/db_to_file dispatch per entity type |
-| ~~B1-18~~ | ~~Finished task TTL eviction (1h, keep last 10)~~ | `lib/bds/tasks.ex:365-386` | **Resolved:** added `finished_task_ttl` (1h) + `recent_finished_limit` (10) config, `FinishedTaskRetention` invariant, `EvictFinishedTasks` rule and `FinishedTaskEvictionDue` runtime event to task.allium |
-| ~~B1-19~~ | ~~`discard_post_changes/1`~~ | `lib/bds/posts.ex:201-227` | **Resolved:** added `DiscardPostChangesRequested` surface event + `DiscardPostChanges` rule (requires file_path, restores published file, content=null/status=published, re-syncs links+FTS) to post.allium |
-| ~~B1-20~~ | ~~`replace_media_file/2` with checksum/backup~~ | `lib/bds/media.ex:288-337` | **Resolved:** added `ReplaceMediaFileRequested` surface event + `ReplaceMediaFile` rule (md5 no-op skip, .bak backup/restore, updates checksum/size/dimensions, synchronous thumbnail regen, FTS re-sync) to media.allium |
-
-### B2. Lower Priority (implementation detail or minor)
-
-| ID | Behavior | Code Location | Resolution |
-|---|---|---|---|
-| ~~B2-1~~ | ~~`editor_body/1` content resolver~~ | `lib/bds/posts.ex:234-256` | **Resolved:** added `editor_body` derived field to the Post entity in post.allium (prefer DB draft content, else read markdown body from file, else empty; same for translations) |
-| ~~B2-2~~ | ~~`sync_post_from_file/1` single-post reimport~~ | `lib/bds/posts.ex:259` | **Resolved:** added `SyncPostFromFileRequested` surface event + `SyncPostFromFile` rule (re-read own .md file, upsert DB, re-sync links) to post.allium |
-| ~~B2-3~~ | ~~`import_orphan_post_file/1`~~ | `lib/bds/posts.ex:293` | **Resolved:** added `ImportOrphanPostFileRequested` surface event + `ImportOrphanPostFile` rule (import a disk .md with no DB row, reject non-markdown) to post.allium |
-| ~~B2-4~~ | ~~`dashboard_stats/1`, `post_counts_by_year_month/1`~~ | `lib/bds/posts.ex:416-450` | **Resolved:** added `ComputeDashboardData` rule to editor_misc.allium (status-grouped counts, (year,month) timeline newest-first limited to recent months, plus clouds/recent) |
-| ~~B2-5~~ | ~~`regenerate_missing_thumbnails/2`~~ | `lib/bds/media/thumbnails.ex:51` | **Resolved:** added `RegenerateMissingThumbnailsRequested` surface event + `RegenerateMissingThumbnails` rule (raster images excl. SVG, regenerate only missing files, background task w/ counts) to media_processing.allium |
-| ~~B2-6~~ | ~~Cache dir computation~~ | `lib/bds/projects.ex:142-147` | **Resolved:** added `cache_dir` derived field (`private_dir/projects/{id}`, :project_cache_root override) to the Project entity in project.allium |
-| ~~B2-7~~ | ~~`remove_stale_published_templates`~~ | `lib/bds/templates.ex:561` | **Resolved:** extended RebuildTemplatesFromFiles in template.allium to prune published templates whose file is neither scanned nor on disk (clearing references first) |
-| ~~B2-8~~ | ~~Rendering Labels module (30+ i18n strings)~~ | `lib/bds/rendering/labels.ex` | **Resolved:** captured as `RenderLabels` value + `LabelsUseContentLanguage` invariant in rendering.allium (with B1-6) — content-language gettext strings + month names |
-| ~~B2-9~~ | ~~Progress reporting during reindex~~ | `lib/bds/generation/progress.ex` | **Resolved:** added `GenerationProgressReported` runtime event + `ProgressReporting` guarantee to generation.allium (count-based + phased fractions, via task progress channel) |

-All reconciled to follow code. Specs must be self-consistent and match code.
-
-| ID | Conflict | Resolution | Path |
-|---|---|---|---|---|
-| C-1 | ~~schema.allium ChatMessage has no cache tokens; ai.allium ChatMessage has `cache_read_tokens`/`cache_write_tokens`~~ | Code has cache tokens → align schema.allium with ai.allium | **Resolved:** added cache_read_tokens + cache_write_tokens to ChatMessage entity and ChatMessageRecordSurface in schema.allium |
-| C-2 | ~~media.allium SidecarFile mentions `linkedPostIds`; frontmatter.allium MediaSidecar does NOT list it~~ | Code writes `linkedPostIds` → add to frontmatter.allium | **Resolved:** linkedPostIds added to MediaSidecar in frontmatter.allium (with A2-15) |
-| C-3 | ~~translation.allium says status/timestamps omitted; frontmatter.allium TranslationFrontmatter defines only 5 fields; code writes 8+ fields~~ | Code writes status/timestamps → update both specs to match code | **Resolved:** both specs updated (see A2-5) |

-## D. Spec Claims Not Covered by Tests
-
-### D1. No Test Coverage (HIGH priority — invariants/guarantees)
-
-| ID | Claim | Spec | Path |
-|---|---|---|---|
-| D1-1 | ~~UniqueMediaTranslation invariant~~ | media.allium:108 | **Resolved:** test added (re-upsert updates not duplicates; direct duplicate insert rejected). Test exposed a real bug — `Media.Translation` declared the migration's index name but ecto_sqlite3 derives the violated-constraint name from columns, so violations crashed instead of returning a changeset error; fixed `unique_constraint` name to `:media_translations_translation_for_language_index` |
-| D1-2 | ~~UniqueTranslationPerLanguage invariant~~ | translation.allium:94 | **Resolved:** test added (re-upsert updates not duplicates; direct duplicate insert rejected). Same bug as D1-1 — `Posts.Translation` declared the migration's index name but ecto_sqlite3 derives the violated-constraint name from columns, so duplicates crashed instead of returning a changeset error; fixed `unique_constraint` name to `:post_translations_translation_for_language_index` |
-| D1-3 | ~~BundledDefaultTemplatesExistOutsideProjectData~~ | template.allium:65 | **Resolved:** added 4 tests in `template_lookup_priority_test.exs` — with no Template rows for the project, `load_template_source/3` resolves bundled single-post/post-list/not-found defaults (and still resolves when the project has no `templates/` directory at all) |
-| D1-4 | ~~UserTemplateDirectoryOverridesBundledDefaults~~ | template.allium:75 | **Resolved:** added 2 tests in `template_lookup_priority_test.exs` — a published project Template row with the bundled default slug (`single-post`) wins over the bundled default both when resolving `:post` with no explicit slug and when the slug is requested explicitly |
-| D1-5 | ~~LiquidTagSubset (5 tags only)~~ | template.allium:179 | **Resolved:** added `BDS.Rendering.LiquidParser`, a restricted Liquex parser recognizing only the subset (if/for/assign/render + `{{ }}` output); any other tag (`unless`, `case`, `capture`, `tablerow`, `cycle`, `increment`, …) leaves unmatched input and fails `eos/0`. Wired into `validate_liquid` (publish gate), `template_selection.render_template`, `filters.render_macro_source`, and MCP `validate_template` so validation and rendering share the same surface; 6 parametrized tests added asserting unsupported tags are rejected at publish |
-| D1-6 | ~~LiquidFilterSubset (4 standard + 2 custom)~~ | template.allium:191 | **Resolved:** added `LiquidParser.validate/1`, which parses with the restricted tag grammar then walks the AST to reject any filter outside the allowed set — 4 standard (`escape`, `url_encode`, `default`, `append`) + 3 custom (`i18n`, `markdown`, `slugify`). Wired into `validate_liquid` (publish gate) and MCP `validate_template` so unsupported filters are rejected even though Liquex would otherwise apply them as built-in standard filters. Spec corrected to 3 custom filters (bundled templates use `slugify`); 9 tests added (6 unsupported filters rejected, 3 supported filters accepted). |
-| D1-7 | ~~LiquidOperatorSubset~~ | template.allium:210 | **Resolved:** `LiquidParser.validate/1` now walks the parsed AST for `{:op, _}` nodes and rejects any comparison operator outside the allowed `==`/`>` subset (`!=`, `<`, `>=`, `<=`, `contains`), sharing the publish gate and MCP `validate_template` surface with the tag/filter checks; spec `LiquidOperatorSubset` annotated with enforcement note; 10 tests added (5 unsupported operators rejected at publish, 5 supported `==`/`>`/`and`/`or`/bare-truthy expressions accepted). |
-| D1-8 | ~~MacroTimeout guarantee~~ | script.allium:94-95 | **Resolved:** added test in `api_test.exs` — an infinite-loop `render()` macro run with `max_reductions: :none` (forces the luerl sandbox onto its wall-clock path) and a 150ms `timeout` returns `{:error, :timeout}` and terminates within budget (<2s), proving the macro is killed near its budget rather than the default multi-minute script timeout |
-| D1-9 | ~~ExecuteTransform rule (pipeline, ordering, toast budget)~~ | script.allium:229-263 | **Resolved:** the `ExecuteTransform` rule had no engine — added `BDS.Scripts.Transforms.run/3` (+ `Scripts.list_transform_scripts/1` ordered by updated_at→slug→id and `Scripts.resolved_content/1`). The pipeline runs enabled project transforms sequentially on the blogmark candidate with a `{source="blogmark", url}` context, captures per-script errors without rolling back the last valid candidate (TransformPipelineContinuation), and enforces the toast budget (`transform_max_toasts_per_script`/`transform_max_toasts_total`/`transform_max_toast_length`, new config keys). 6 tests added (ordering, project/disabled scoping, continuation, context, per-script + total toast caps with truncation). Deep-link OS routing into this engine remains future work. |
-| D1-10 | ~~TransformPipelineContinuation~~ | script.allium:247-249 | **Resolved:** added focused test in `transforms_test.exs` — a failing *first* transform (no prior valid state) does not halt the pipeline: the original input survives, a later enabled transform still runs against it, and every failure is captured per-script in pipeline order tagged with its slug |
-| D1-11 | ~~ChatContextTruncation invariant~~ | ai.allium:375-379 | **Resolved:** test added in `ai_test.exs` — a catalog model with a 2,000-token context window plus 40 large seeded turns forces truncation; the captured chat request keeps the system prompt as the first message, drops the oldest pairs first (surviving markers form a contiguous newest suffix, oldest absent), and always retains the newest user turn |
-| D1-12 | ~~BoundedToolLoop enforcement~~ | ai.allium:381-385 | **Resolved:** the round cap is now read from `config.chat_max_tool_rounds` (`config :bds, :chat, max_tool_rounds: 10`) via `chat_max_tool_rounds/0` in chat.ex instead of a hardcoded attribute, matching the spec wording; test added in `ai_test.exs` — a `LoopingToolRuntime` that always returns another tool call (never a final answer) with `max_tool_rounds: 3` ends with `{:error, %{kind: :tool_loop_exhausted}}` after exactly 3 runtime calls (the `rounds_left == 0` round short-circuits before contacting the runtime) |
-| D1-13 | ~~DiscardPostChangesSideEffects~~ | engine_side_effects.allium:99-104 | **Resolved:** test added in `posts_test.exs` — a published post is dirtied with unsaved title/content edits (re-indexing the dirty text in FTS), then `discard_post_changes/1` restores the published file version (status=published, content=nil, original title) and re-syncs the FTS index so the published terms are searchable again and the discarded edits are gone |
-| D1-14 | ~~ReplaceMediaFileSideEffects~~ | engine_side_effects.allium:128-134 | **Resolved:** 3 tests added in `media_test.exs` — `replace_media_file/2` copies the new image over the existing path, updates the row (checksum/size/width/height), and regenerates all thumbnails synchronously (present immediately after the call, no `.bak` backup left); identical-checksum replace is a no-op (`{:ok, nil}`); unknown media id returns `{:error, :not_found}` |
-| D1-15 | ~~Drag-and-drop image chain~~ | action_patterns.allium:84-103 | **Resolved:** the chain had no handler — added `BDS.Desktop.ShellLive.EditorImageDrop` (`import_and_link/3` runs steps 1-4: import media + synchronous thumbnails + link to post + return `![](bds-media://id)` markdown; `enrich/3` runs background steps 5-6: AI analysis auto-applied with no modal + auto-translate cascade when `do_not_translate == false`). `PostEditor.handle_event("editor_image_dropped", ...)` runs the synchronous chain (works offline since import isn't AI), pushes the cursor insert, and spawns `enrich` only when airplane mode is off. MonacoEditor JS hook captures image drops on the editor surface and pushes the file path (`phx-target={@myself}` routes the hook event to the component); i18n for de/fr/it/es. 3 tests added (module chain incl. thumbnails+link+markdown, non-image link form, full LiveView drop in airplane mode asserting import/link/insert with no AI metadata). |
-| D1-16 | ~~DebouncedPersistence (5s)~~ | embedding.allium:213-217 | **Resolved:** 3 tests added in `embeddings_test.exs` (DebouncedPersistence describe): `Index.put/3` schedules a per-project save `timer` with ~5s remaining (>4000ms, <=5000ms) instead of writing immediately (no `embeddings.usearch` on disk yet); rapid `put`s coalesce (each reschedules the single timer, the previous timer is cancelled so `Process.read_timer` returns false, and still no file after two writes); when the `{:save, project_id}` debounce message fires the index is persisted to disk and the pending `timer` cleared. The coalescing test exposed a real bug: `handle_call({:put, ...})` replaced the stored entry with `build_entry/2`'s fresh `timer: nil` entry before `schedule_save/2` ran, orphaning the previous debounce timer (left to fire a redundant save) instead of cancelling it; fixed via `cancel_pending_save/2` so bulk `put`s collapse to one deferred write |
-| D1-17 | ~~Protected categories cannot be deleted~~ | editor_settings.allium:81-84 | **Resolved:** 5 tests added in managed_categories_test.exs covering protected_category?/1 classification and remove_category/4 rejection for all 4 protected categories (article, aside, page, picture) plus non-protected deletion allowed |
-| D1-18 | ~~HomeItemProtection (menu)~~ | editor_misc.allium:206-209 | **Resolved:** 13 tests added for TreePredicates (can_move_up?/can_move_down?/can_indent?/can_unindent? return false for Home, can_delete? false for Home, true for non-Home) + TreeOps (move_selected/indent_selected/unindent_selected/delete_selected no-op for Home, drop_selected no-op when drag item is Home, non-Home operations still work); code guards added to all predicate and operation functions |

-| ID | Claim | Spec | Path |
-|---|---|---|---|
-| ~~D2-1~~ | ~~RemoveCategory rule~~ | ~~metadata.allium:100~~ | **Resolved:** 2 tests added in metadata_test.exs — remove_category removes category+settings from state/files/DB (6 assertions); remove_category is a no-op for non-existent category |
-| ~~D2-2~~ | ~~CreateAndPublishTemplate rule~~ | template.allium:105 | **Resolved:** added `create_and_publish_template/1` (validates Liquid, creates published template + writs file), 3 tests added (happy path file assertions, invalid liquid rejection, slug dedup on title conflict) |

-|---|---|---|---|
-| ~~D4-1~~ | ~~editor_media.allium~~ | ~~AI analysis, delete~~ | ~~Translate, replace file, link-to-post, translation CRUD, detect language~~ | **Resolved:** backend tests cover replace_file, link-to-post, translation CRUD (upsert + unique constraint); added standalone `delete_media_translation/2` test (row + sidecar deletion, no-op for non-existent, not-found for unknown media); added `MediaDetectLanguage` rule integration test (AI mock, language persisted, sidecar rewritten) |

Total 56 tests added across MCP agents, style/theme, search filter, and categories CRUD. |
-| D4-3 | ~~editor_chat.allium~~ | ~~Chat creation, pinned tab~~ | ~~API key screen, message rendering, input area, model selector, inline surfaces~~ | **Resolved:** 3 tests added — WelcomeScreen assertions (robot icon, title, 5 tips), CSP external image rewriting in markdown, chart inline surface rendering with series labels/values |
-| D4-4 | editor_script.allium | Editor layout, create defaults | ~~Save, syntax check, run, delete~~ | **Resolved:** 4 tests added — save persists title change + version bump to DB, run executes script without crash, check syntax validates without side effects, delete removes DB record + file |
-| D4-5 | editor_template.allium | Editor layout, create defaults | ~~Save with validation, validate, delete with references~~ | **Resolved:** 6 tests added in template_editor_live_test.exs covering save with valid Liquid (version bumps), save with invalid Liquid (rejected, version unchanged), validate (no side effects), delete (removes DB row + .liquid file), delete with references (clears post template_slug) |
-| D4-6 | editor_tags.allium | Sync/discover, merge | ~~Cloud sizing, color picker, delete confirmation, create form~~ | **Resolved:** 17 tests added covering `tag_font_size`/`tag_style` unit tests, colour picker preset swatches + pick event, create-form end-to-end, delete-confirmation overlay (now opens confirm dialog instead of immediate delete), cloud sizing UI with font-size assertions, and coloured tag inline styles |

+# TUI Editor — Implementation Plan (Issue #32)
+
+Tracking issue: **#32** — "markdown, liquid and lua code editor with syntax
+highlighting in the TUI".
+Spec under change: `specs/tui.allium`.
+
+Goal: a syntax-highlighted, word-wrapping TUI editor for posts (markdown
+with `[[macro]]` syntax), templates (HTML + Liquid), and scripts (Lua),
+replacing the current plain `ExRatatui.Widgets.Textarea` body.
+
+## Decision: pure Elixir — no new Rust
+
+`ExRatatui` already ships everything we need:
+
+- `ExRatatui.CodeBlock.highlight/3` (`deps/ex_ratatui/lib/ex_ratatui/code_block.ex:103`)
+  returns `[%ExRatatui.Text.Line{}]` of styled spans via the bundled
+  syntect NIF. Supports Lua, Markdown, HTML, … out of the box.
+- `ExRatatui.Widgets.CodeBlock` is read-only; we do **not** use it
+  directly for editing.
+- `ExRatatui.Widget` protocol (`deps/ex_ratatui/lib/ex_ratatui/widget.ex:1`)
+  lets us implement a custom widget in pure Elixir that composes
+  primitives every frame. This is the seam we use.
+- The editing engine stays Rust-owned
+  (`ExRatatui.textarea_new/0`, `textarea_handle_key/3`, `textarea_get_value/1`,
+  `textarea_cursor/1`, `textarea_line_count/1`). The custom widget only
+  re-renders the buffer through a styling + wrap pipeline.
+- `ExRatatui.Widgets.Paragraph` accepts `[%Text.Line{}]` of styled spans
+  with `wrap: true` and a `scroll: {vertical, horizontal}` offset —
+  exactly the output shape we need.
+
+The existing comment at `lib/bds/tui.ex:1451-1454` already pre-announces
+this approach as "the planned MarkdownEditor custom widget".
+
+Languages supported (matches GUI Monaco registrations in
+`assets/js/monaco/languages.js`):
+
+| Entity                | Base lexer (NIF) | Elixir overlay                  |
+|-----------------------|------------------|---------------------------------|
+| post body             | `markdown`       | `[[macro …]]` recoloured        |
+| script body           | `lua`            | none                            |
+| template body         | `html`           | `{{ … }}` and `{% … %}` recoloured |
+
+Liquid is always HTML+Liquid in this codebase (no markdown+Liquid
+templates exist). Plain text falls back to syntect's plain renderer.
+
+## GUI styling parity (from `assets/js/monaco/theme.js` + `languages.js`)
+
+- **macro** `[[ … ]]` → `keyword.macro` = `#C586C0`, **bold**.
+- inside macro: `attribute.name` (e.g. `names`) → `#9CDCFE`,
+  `attribute.value` (e.g. `"x"`) → `#CE9178`.
+- Liquid uses base vs-dark tokens; terminal approximation uses the same
+  base theme accent colours. No custom Liquid token colours overridden.
+
+Use `{:rgb,197,134,192}` etc. via `ExRatatui.Style` (already supported
+by `ExRatatui.CodeBlock.from_native/1`).
+
+## Architecture
+
+```
+state.editor.textarea            (unchanged, Rust-owned buffer/cursor/undo)
+state.editor.language            (:markdown_macros | :liquid | :lua | :text)
+state.editor.preview?            (unchanged ctrl+e toggle — default false for posts)
+
+body_widget/3  edit branch:      %BDS.UI.CodeEditor{textarea:, language:, theme:, wrap:, cursor_style:, line_highlight_style:, block:}
+                                 ↳ impl ExRatatui.Widget.render:
+                                      1. content = ExRatatui.textarea_get_value(textarea)
+                                      2. {row, col} = ExRatatui.textarea_cursor(textarea)
+                                      3. lines = BDS.UI.CodeEditor.Highlight.highlight(content, language, theme)
+                                      4. apply current-line bg style into every span on lines[row]
+                                      5. cut the span at byte col on lines[row], splice cursor-style cell
+                                      6. top = vertical-scroll offset so cursor visual row stays in window (Latin-width count)
+                                      7. return [{%Paragraph{text: lines, wrap: true, scroll: {top,0}, block: block}, rect}]
+```
+
+`editor_key/1` in `lib/bds/tui.ex` keeps calling
+`ExRatatui.textarea_handle_key/3` — no edit-model rewrite, the
+textarea's own undo/redo/clipboard keeps working.
+
+## Phases (test-first, per AGENTS.md)
+
+### Phase 0 — Spec
+
+Edit `specs/tui.allium`:
+
+- `OpenEntry`: posts open in the **editor** (wrap on, highlighting on)
+  by default — not the rendered Markdown preview. New empty posts still
+  open in the editor (unchanged).
+- Rename `WrappedPreview` → `EditorMode`: `ctrl+e` toggles editor ↔
+  read-only rendered-Markdown preview (via `ExRatatui.Widgets.Markdown`).
+  Drop the "textarea cannot wrap" caveat.
+- Add `CodeEditorWrapping` rule: syntax highlighting + auto wrap +
+  highlighted current line. Explicitly **no line-number gutter**.
+- Validate with `allium check specs/tui.allium`.
+
+### Phase 1 — Red tests
+
+New file `test/bds/ui/code_editor_test.exs`:
+
+- `BDS.UI.CodeEditor.Highlight.highlight/3` for `:lua` colours a
+  `function … end` keyword with the theme's keyword colour.
+- `:markdown_macros` recolours `[[gallery names="x"]]`:
+  - `[[`, `]]` and macro name → `{:rgb,197,134,192}` bold
+  - `names` → `{:rgb,156,220,254}`
+  - `"x"` → `{:rgb,206,145,120}`
+  - surrounding markdown still base-styled.
+- `:liquid` recolours `{{ x }}` and `{% if x %}` over an HTML base;
+  `if` keyword distinct from identifiers.
+- Widget emits a `%Paragraph{wrap: true, scroll:}`, never a bare `%Textarea`,
+  when language is one of the highlighted set.
+
+Extended `test/bds/tui_test.exs`:
+
+- Opening an existing post lands in the **editor** (`preview? == false`),
+  not the rendered preview. Replace the assertion in
+  `test "opening a post lands in the markdown preview, not the editor"`.
+  Test name/logic flips.
+- Long line wraps across N visual rows in a 40-wide viewport
+  (assert via `CellSession.take_cells/1`).
+- Cursor at the last visual row stays visible when scrolling a small
+  viewport (assert cursor-style cell appears in snapshot cells).
+- Current line's cells have a distinct `bg` from non-current rows on
+  the same buffer.
+- `ctrl+e` flips to preview and back; preview still rendered Markdown.
+- `ctrl+s` persists textarea bytes unchanged regardless of highlight/wrap
+  (existing assertion still covers this — keep it green).
+
+### Phase 2 — `lib/bds/ui/code_editor/highlight.ex` + `overlay.ex`
+
+- `BDS.UI.CodeEditor.Highlight.highlight(content, language, theme)` →
+  `[%ExRatatui.Text.Line{}]`:
+  - `:lua`, `:text` → pass straight through to
+    `ExRatatui.CodeBlock.highlight/3`.
+  - `:markdown_macros` → base highlight as `"markdown"`, then apply
+    `Overlay.markdown_macros/1` per source line.
+  - `:liquid` → base highlight as `"html"`, then apply
+    `Overlay.liquid/1` per source line.
+- `BDS.UI.CodeEditor.Overlay`:
+  - `apply_ranges(line, ranges_with_styles)` — re-splits a `Line`'s
+    spans into a new span list, preserving the base styling outside
+    each range.
+  - `markdown_macro_ranges/1` — `~r/\[\[\s*[a-zA-Z][\w-]*[^]]*\]\]/s`.
+  - `macro_inner_ranges/1` — break `attr=` (attr-name) and quoted value
+    into separate styled sub-ranges inside a macro.
+  - `liquid_ranges/1` — `~r/(\{\{.*?\}\}|\{%-?\s*(\w+).*?-?%\})/s`,
+    with a sub-range for the tag keyword (`if`, `for`, `assign`, …).
+- Cache results by `{content_hash, language, theme}` if profiling shows
+  re-tokenisation overhead on keystroke (Phase 2 stretch goal —
+  skip until a test says otherwise).
+
+### Phase 3 — `lib/bds/ui/code_editor/widget.ex`
+
+- `%BDS.UI.CodeEditor{}` struct fields: `textarea`, `language`,
+  `theme` (default `:base16_ocean_dark`, readable in dark terminals),
+  `wrap: true`, `cursor_style`, `line_highlight_style`, `block`, `scroll`.
+- `defimpl ExRatatui.Widget` per the pipeline above.
+- Cursor cell: re-style the single codepoint at `col` on source line
+  `row` into `cursor_style`. Paragraph wraps the same line; the styled
+  cell rides the wrap.
+- Scroll math: count display rows by wrapping each source line into
+  `width` columns (Latin-width assumption — 1 char = 1 cell). Note the
+  limitation explicitly; CJK width is a follow-up if/when needed.
+- Line highlight: apply `line_highlight_style` (a `bg:` colour) to
+  every span on the cursor's source line before cursor cut-in.
+
+### Phase 4 — Wire into `lib/bds/tui.ex`
+
+- `build_editor/4` (around `lib/bds/tui.ex:1968`): default
+  `preview? = false` for existing posts. New posts already open in
+  editor — unchanged.
+- `body_widget/3` edit branch (`lib/bds/tui.ex:1466`): emit
+  `%BDS.UI.CodeEditor{}` instead of `%ExRatatui.Widgets.Textarea{}` for
+  entities that have a syntax highlighter (`:lua`, `:markdown_macros`,
+  `:liquid`). Plain text can keep `%Textarea{}` or feed `:text` through
+  the new widget — pick whichever keeps the test surface smaller.
+- Remove the "wrap limitation" comment block at
+  `lib/bds/tui.ex:1451-1454`.
+- `cycle_language/1` continues per post; cycle through the active
+  set (`:markdown_macros`, `:liquid`, `:lua`, `:text`) matching the
+  existing GUI editor language options.
+- Preview branch (`body_widget/3` preview arm at `lib/bds/tui.ex:1455`)
+  stays on `ExRatatui.Widgets.Markdown` — unchanged.
+- No new user-facing strings: the existing body title already flows
+  through `dgettext("ui", …)`. If a new toolbar/hint is added later,
+  it MUST go through gettext and provide de/fr/it/es translations.
+
+### Phase 5 — Verify
+
+- `mix test` (write to `/tmp/test_run.log` first, grep for failures —
+  per AGENTS.md).
+- `mix credo --strict`
+- `mix deps.audit --ignore-file .mix_audit.ignore`
+- `mix dialyzer` — treat warnings as errors.
+
+No bundle rebuild, no asset change, no NIF rebuild. Monaco still drives
+the GUI editor; this change is TUI-only.
+
+## Risks / limits
+
+- **Per-frame NIF cost:** re-tokenises the whole buffer on every
+  keystroke. For typical post sizes (<50 KB) syntect is sub-ms. Add the
+  `{content_hash, language, theme}` cache only if a test shows it.
+- **CJK cell width:** wrap math assumes 1 char = 1 cell. Fine for
+  de/fr/it/es. Note as TODO; not in scope for this phase.
+- **Liquid mis-lexing inside HTML** is cosmetically possible (an HTML
+  attribute containing `{{`). Overlay wins after the base lexer; the
+  result is visually tolerable. A custom `.sublime-syntax` in the
+  dep would be the real fix — out of scope here per "stay on Elixir".
+- **Cursor in a wrapped paragraph** rides the styled cell. Equivalent
+  to a cell-caret; GUI uses a real caret — acceptable TUI parity.
+
+## Files touched (expected)
+
+- `specs/tui.allium` — edited.
+- `lib/bds/ui/code_editor/highlight.ex` — new.
+- `lib/bds/ui/code_editor/overlay.ex` — new.
+- `lib/bds/ui/code_editor/widget.ex` — new.
+- `lib/bds/tui.ex` — edited (`build_editor`, `body_widget`, comment
+  removal, default `preview?`).
+- `test/bds/ui/code_editor_test.exs` — new.
+- `test/bds/tui_test.exs` — edited (flip the "opens in preview"
+  assertion, add wrap/cursor/current-line tests).
+
+No changes to `mix.exs`, no new deps, no Rust, no assets.
