Tree clean on `slice-2-editor`. **Commit:** `bf4b5f3` — feat: editor shell with text editing, live sync and undo **Tests:** - `make ci` green (vet, gofmt, `go test ./...`, migration check); 4 new slidestest tests (page + bundle linkage/immutability, membership 404/200 + Edit button, empty deck, thumb viewport). - `cd fixtures &amp;&amp; node --test`: 68 pass, 0 fail (Docs' 22 copied verbatim + frames/stage/changes/text-keys/strip). - Browser drive RAN (Chromium `/usr/bin/chromium`, sandbox off — its process-singleton `socket()` is denied inside the sandbox): 4/4 pass — type into the title → Saved → reload persists → viewer shows it; New slide + Undo via the menu; a second signed-in client's `set_text` over the wire redraws the open stage without reload. No console errors or failed requests. - Bundle reproducible: two builds, same hash `editor.a12c76754a081686.js`. **Concerns:** - `yUndoPlugin` not used: its view `destroy` hook destroys the manager it is handed, which would kill a shared `Y.UndoManager` on every `refresh()`; the shared manager is driven directly with `trackedOrigins = {ySyncPluginKey, 'local'}` (verified against sync-plugin.js). Undo does not restore the caret. - `render.go` untouched: blocks already carry `data-id`/`data-block`, so the stage binds on those rather than a new `data-block-id`. - Table cells and shape labels not bound (deferred to Task 4 as allowed). Presence not wired. A remote structural change to the current slide drops the caret. `10-gate` still lacks `npm ci`/`node --test`/bundle check. `node --test fixtures/` (directory arg) misbehaves on Node 24; run from `fixtures/`. **Report:** `/home/paulca/amadan.net/oficina/slides/.claude/worktrees/slice-1/.superpowers/sdd/2026-09-07-slice-2-editor/task-3-report.md`</result> <usage><subagent_tokens>338042</subagent_tokens><tool_uses>177</tool_uses><duration_ms>1755825</duration_ms></usage> </task-notification>

Their three test files likewise. | **Named-risk results** - **(a) `trackedOrigins`** — sound. `sync-plugin.js:655` uses `ySyncPluginKey` as the transaction origin in `_prosemirrorChanged`; yjs matches origins by identity (`yjs.cjs:3663`). Remote bytes carry `'remote'`, so **you cannot undo another person's edit**. No leaks: `refresh()` → `load()` → `unbind()` destroys every view before replacing `innerHTML`; `attemptResync` destroys the stage, stops live-updates and calls `undoManager.destroy()` before rebuilding. The `yUndoPlugin` deviation is justified — `undo-plugin.js:120-121` does call `undoManager.destroy()` on view destroy and never removes its `stack-item-added`/`-popped` listeners, so a shared manager would die with the first view unmounted. - **(b) Save path** — `doc.on('update')` returns early on `origin === REMOTE`; load applies with `'remote'`. Correct. - **(c) Cursor** — `initialSeq` from `since=0`'s `Slides-Seq`; `noteOwnSeq` adopts only `cursor + 1`; `fetchSince(cursor)` → `?since=N` exclusive; cursor advances by `max`, never assignment. Correct. - **(d) XSS** — every `innerHTML` is the server's `render.Slide` output; `labelFor` uses `textContent`. Server-side `safeHref` allowlists link schemes (tested in `render_test.go:405`). - **(f) Scriptless floor** — page reads whole without JS; noscript links the viewer. - **(g)/(h)** — clean. Thumbnails are `inert` so the deck isn't duplicated in the tab order; the stretched-link `::after` carries the focus ring; menu is `&lt;details&gt;` + real buttons. - **(i)** — `TestBrowserEditsTheTitle` really reloads and re-reads the heading, the strip label and the viewer; `TestBrowserSeesAnotherWriter` posts core-made bytes from a second signed-in client and waits for the open stage to redraw, then asserts the status never left "saved". ## Strengths - The Docs modules are genuinely verbatim — I diffed all six files. The header is honest about what changed. - `changes.mjs` is the right abstraction: one pure walk from event target to slide map decides text vs. structure vs. order, driven in tests with real `observeDeep` events. - The pure/impure split in `stage.mjs` and `strip.mjs` is disciplined — `textBlocks`, `mountTarget`, `paragraphTag`, `slideAfter`, `labelFor`, `plan` all testable under plain Node with a stub, and they are tested. - Mounting the view *into* the renderer's own block element (`{mount: target}`) with a `paragraph` nodeView per block type is a neat way to honour "no second renderer" while still getting live text. - The commit avoided touching `render.go`'s attributes by binding on the existing `data-id`/`data-block` — no golden churn, as reported. - `assets_embed.go` refuses to start on zero or two bundles, with an error message that names the fix. ## Issues ### Critical None. ### Important 1. **"New slide" is broken on an empty deck** — `internal/slides/templates/editor.html:91-99` renders `[slides-stage]` only under `{{if .HasSlides}}`, so on an empty deck `mountStage`'s `stageEl` is `null`. `stage.load('')` guards it (`if (stageEl)`), but the loaded path does not: after `newSlide()` sets the hash, `load(id)` reaches `stageEl.innerHTML = html` and throws `TypeError`, swallowed by `showSlide`'s `catch` into a console line. The slide *is* created and appears in the strip, but the stage stays on the empty state until a reload — and there is no notes pane either. `TestEditorOfAnEmptyDeck` asserts the page *offers* "New slide" but not that it works. Fix: render the `[slides-stage]` / `[slides-notes-pane]` containers unconditionally and put the empty state inside `[slides-stage]`. 2. **The `ETag` on `GET /d/{sqid}/slides/{id}.html` is inert, and its comment says otherwise** — `internal/slides/editor.go` sets the header, then unconditionally `WriteHeader(200)` and writes the body. The comment claims "this is what makes the fetch that changed nothing cheap", which is false: nothing checks `If-None-Match`. The package already has `matchesETag` (`internal/slides/api.go:409`) and `api.go` uses it. Either add the two-line 304 branch or delete the claim. 3. **A `javascript:` URL from the link dialog renders as a live anchor inside the editor** — `fixtures/schema.mjs:43` is `toDOM: mark =&gt; ['a', { href: mark.attrs.href }, 0]` with no scheme check, and `&lt;input type="url"&gt;` accepts `javascript:alert(1)` as a valid absolute URL. The server is safe (`safeHref` drops it on render, tested), so this never reaches the viewer — but a collaborator can plant one and it becomes a live `&lt;a href="javascript:…"&gt;` in *your* editor DOM, executable on Ctrl/Cmd-click or middle-click. The allowlist already exists server-side; mirror it in `setLink`/`linkPrompt` (or in the schema's `toDOM`). Low severity, one-line fix, and task 3 is what made it reachable. 4. **A failed slide fetch leaves `stage.slideId` ahead of the DOM, silently** — `stage.mjs`'s `load()` assigns `current = id` *before* the `await fetchSlide(...)`. Offline, the fetch rejects, `showSlide` logs to the console, and the stage keeps the previous slide's DOM and bound views while `stage.slideId` and `location.hash` both name the new one. `duplicateSlide()` then duplicates a slide the person isn't looking at. Nothing on screen says anything went wrong — the status line only tracks saves. Assign `current` after the fetch resolves (or roll it back on throw), and consider surfacing the failure. ### Minor 5. **The refresh rule keys on `REMOTE` only, so undo of a structural change won't re-fetch the stage** — `editor-entry.js`: `if (id === current &amp;&amp; tr.origin === REMOTE) showSlide(current)`. An undo transaction's origin is the `Y.UndoManager` instance, neither `REMOTE` nor `LOCAL`. No in-scope command hits this (undoing new/duplicate changes the slide *order*, which the `c.order` branch handles), but Task 4's block-level structural edits will. Worth handing over explicitly. 6. **A permanently dropped batch reads as "Offline, retrying"** — the save queue distinguishes `'failed'` (4xx, edits are gone, never retried) from `'retrying'` (5xx/network); `setStatus` collapses both into `offline`, and `sessionFailed` makes it stick forever after. Docs keeps a distinct `data-state="failed"`. The three-state status line is what the brief prescribed, so this is a plan-level gap to raise rather than a task deviation — but the copy promises a retry that will not happen. 7. **`wantedSlide()` can throw on a hand-crafted hash** — `decodeURIComponent(location.hash.slice(1))` raises `URIError` on e.g. `#%`. In `attemptResync` that fails the whole mount (`data-editor-failed`); in the `hashchange` listener it's uncaught. Slide ids are base32 so this needs a deliberate URL, but a `try`/`catch` costs nothing. 8. **`mountLinkDialog.open()` dangles if called while open** — the second call overwrites `resolve`, so the first promise never settles. `linkPrompt` awaits it, so that `await` never returns. 9. **`strip.sync()` re-appends every item on any order change**, which moves a focused strip link in the DOM; in several browsers that blurs it. A remote reorder can therefore steal a keyboard user's focus. 10. **Stale example hash in a doc comment** — `assets_embed.go` says `"editor" to "editor.f13f5e0ce6fa7467.js"`; the committed file is `editor.a12c76754a081686.js`. 11. **`data-seq`, `data-client-name`, `data-client-colour` are rendered and tested but unread by the bundle** — expected for presence (Task 5), noted in the report; `data-seq` in particular is redundant with the `Slides-Seq` header the loader already trusts. 12. **The `raw=1` retry in `live-updates.mjs` is dead weight here** — Slides' server ignores the parameter, so a decode failure re-fetches identical bytes, throws again, and wedges without ever reporting divergence. The report flags it as harmless; it's the price of "verbatim", so I'd leave it and note it for the slice-4 extraction. 13. **`[slides-thumb-frame] { transform: scale(0.2) }` is a hard-coded 180/900** while `[slides-thumb] { width: 100% }` in the wide layout — the fit depends on the 200px column and `--rst-sp-2` staying exactly what they are today. ## Assessment **Task quality:** Needs fixes **Reasoning:** The spec compliance is genuinely high and the hard parts are right — the copied modules are verbatim, the origin/cursor arithmetic is correct on every axis the brief named, undo is properly scoped to this client, the `yUndoPlugin` deviation is well-reasoned and I confirmed it against the library source, and the browser drive really asserts the two things that matter (persistence across reload, remote redraw on the open stage). Nothing here is architecturally wrong and nothing needs redoing. What holds it back is issue 1: the editor's primary action on an empty deck creates the slide and then fails to show it, swallowed into a console line — and the Go test for that page checks the button exists rather than that it works. Issues 2-4 are each small and local (a missing 304 branch plus a comment that lies about it; a scheme check the codebase already implements server-side; an assignment on the wrong side of an `await`). All four are a short pass, and none of them touches the design.</result> <usage><subagent_tokens>138037</subagent_tokens><tool_uses>57</tool_uses><duration_ms>478292</duration_ms></usage> </task-notification>
