# Unified Tasks Board — Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Add a "Tasks" tab — a 5-column Kanban board (Queue/Running/Ready/Interrupted/Done) covering every task regardless of story association, with an inline auto-tailing execution-log excerpt on every card (no click required).

**Architecture:** Almost entirely a generalization of existing, working (but currently dead/disconnected) code in `web/app.js`: `createTaskCard`, `renderTasksIntoContainer`, the Stories board's column-grouping pattern (`STORY_COLUMNS`/`columnForStatus`/`groupStoriesByColumn`), and the old Running tab's per-task SSE log-tailing (`startRunningLogStream`). No Go/backend changes — every REST endpoint this needs (`/api/tasks`, `/api/executions?task_id=`, `/api/executions/{id}/logs/stream`) already exists and is already exercised by existing Go tests.

**Tech Stack:** Vanilla JS (no framework), `node --test` for unit tests (hand-rolled DOM mocks per test file, no jsdom), existing CSS conventions in `web/style.css`.

## Global Constraints

- No backend/Go changes in this plan — verify with `go test ./...` at the end regardless, as a safety check (per spec).
- Follow the existing DOM-mock testing convention: no jsdom: dependency-inject `doc`/`fetchFn`/`EventSourceImpl` params with real-global defaults, matching `renderEventTimeline(events, doc = document)` and `fetchRecentExecutions(basePath, fetchFn = fetch)`'s existing pattern in `web/app.js`.
- Column partition (from the approved spec, `docs/superpowers/specs/2026-07-06-tasks-board-design.md`) is fixed: Queue = PENDING/QUEUED; Running = RUNNING/BLOCKED; Ready = READY; Interrupted = FAILED/TIMED_OUT/CANCELLED/BUDGET_EXCEEDED; Done = COMPLETED.
- Default landing tab stays `'stories'` — do not revert to `'queue'`.
- Do not touch `renderRunningHistory`, `sortExecutionsByDate`/`sortExecutionsDesc`, or `fetchRecentExecutions` — these back a separate, still-valid (if currently unreached) system-wide execution-history feature, not superseded by this board.
- Do not touch `filterQueueTasks`, `filterReadyTasks`, `filterAllDoneTasks`, `filterTasksByTab`, `filterActiveTasks`, `filterTasks`, or their test files (`tab-filters.test.mjs`, `filter-tabs.test.mjs`, `active-tasks-tab.test.mjs`, `filter.test.mjs`) — dead-but-harmless, unrelated pre-existing debt, out of scope for this plan.

## File Map

| File | Change |
|---|---|
| `web/app.js` | Add `TASK_COLUMNS`, `columnForTaskState`, `groupTasksByColumn`; extend `createTaskCard` (DI `doc` param, log-tail placeholder, elapsed timer); add `cardContentSignature`, modify `renderTasksIntoContainer`; add `ensureTaskLogStream`/`taskLogStreams` (replacing `startRunningLogStream`/`runningViewLogSources`); add `renderTasksBoard`; wire `case 'tasks':` into `renderActiveTab`; remove `renderQueuePanel`, `renderInterruptedPanel`, `renderReadyPanel`, `renderRunningView`, `isRunningTabActive`, old `startRunningLogStream`, `runningViewLogSources`, old `updateRunningElapsed` |
| `web/index.html` | Add Tasks nav button + `[data-panel="tasks"]` container |
| `web/style.css` | Add `.tasks-board`/`.tasks-column*` (reusing `.stories-board`/`.stories-column*` declarations) and `.task-log-tail` (compact log excerpt) |
| `web/test/tasks-board.test.mjs` | New — column model + card/log-tail/diff-preservation unit tests |
| `web/test/tab-persistence.test.mjs` | Fix 2 pre-existing failing assertions (`'queue'` → `'stories'`) |

---

## Task 1: Column model — `TASK_COLUMNS`, `columnForTaskState`, `groupTasksByColumn`

**Files:**
- Modify: `web/app.js` (add near `STORY_COLUMNS`, e.g. directly after `groupStoriesByColumn`, ~line 3360)
- Test: `web/test/tasks-board.test.mjs` (new file)

**Interfaces:**
- Produces: `TASK_COLUMNS` (array of `{key, label, states}>`), `columnForTaskState(state) → string`, `groupTasksByColumn(tasks) → {[columnKey]: task[]}` — consumed by Task 7 (`renderTasksBoard`).

- [ ] **Step 1: Write the failing tests**

Create `web/test/tasks-board.test.mjs`:

```js
// tasks-board.test.mjs — Unit tests for the unified Tasks board's pure
// column-grouping logic. Mirrors web/test/stories-board.test.mjs's structure.

    // Replace the bogus 'DONE-n/a' state task with a real COMPLETED one for a clean grouping check.
    tasks[2] = makeTask('COMPLETED', '2026-01-01');
    const groups = groupTasksByColumn(tasks);
    assert.equal(groups.queue.length, 1);

    assert.deepEqual(groups.queue.map(t => t.created_at), ['2026-01-01', '2026-01-02', '2026-01-03']);
  });

});
```

- [ ] **Step 2: Run tests to verify they fail**

Run: `node --test web/test/tasks-board.test.mjs`
Expected: FAIL — `TASK_COLUMNS`/`columnForTaskState`/`groupTasksByColumn` are not exported from `../app.js` yet (`SyntaxError` or `undefined` import errors).

- [ ] **Step 3: Implement**

In `web/app.js`, immediately after `groupStoriesByColumn`'s closing brace (after the block ending `storyHasReachedValidation` — insert right after that function, before the `// ── Stories tab: epic swimlanes` comment, i.e. directly following the Stories-board pure-function section), add:

```js
// ── Tasks tab: board/column model (pure — unit-tested in web/test) ─────────
//
// Columns partition the full task.State lifecycle (internal/task/task.go)
// into 5 mutually-exclusive buckets. BLOCKED groups with Running (not an
// error — the task is actively in-flight, just paused on a subtask or an
// ask_user answer). TIMED_OUT/BUDGET_EXCEEDED group with Interrupted (both
// are abnormal stops needing a human decision, same bucket as FAILED/
// CANCELLED — all four already have Resume/Restart buttons via createTaskCard).
export const TASK_COLUMNS = [
  { key: 'queue',       label: 'Queue',       states: ['PENDING', 'QUEUED'] },
  { key: 'running',     label: 'Running',     states: ['RUNNING', 'BLOCKED'] },
  { key: 'ready',       label: 'Ready',       states: ['READY'] },
  { key: 'interrupted', label: 'Interrupted', states: ['FAILED', 'TIMED_OUT', 'CANCELLED', 'BUDGET_EXCEEDED'] },
  { key: 'done',        label: 'Done',        states: ['COMPLETED'] },
];

// columnForTaskState returns the column key for a given task state, falling
// back to 'queue' for an empty/unrecognized state so a task is never
// dropped off the board entirely.
export function columnForTaskState(state) {
  const col = TASK_COLUMNS.find(c => c.states.includes(state));
  return col ? col.key : 'queue';
}

// Per-column sort direction, matching the semantics the old (removed)
// queue/interrupted/ready panels already used — not a uniform order. See
// docs/superpowers/specs/2026-07-06-tasks-board-design.md for rationale.
const TASK_COLUMN_SORT_DESCEND = {
  queue: false,       // oldest-first (FIFO)
  running: true,      // newest-first (no faithful precedent; inconsequential, bounded by max_concurrent)
  ready: false,        // oldest-first (longest-waiting-for-review surfaces first)
  interrupted: true,  // newest-first (most recent failure most urgent)
  done: true,          // newest-first (most recent completion most relevant)
};

// groupTasksByColumn returns { [columnKey]: task[] }, each sub-array sorted
// per TASK_COLUMN_SORT_DESCEND via the existing sortTasksByDate helper.
export function groupTasksByColumn(tasks) {
  const groups = {};
  for (const col of TASK_COLUMNS) groups[col.key] = [];
  for (const t of tasks || []) {
    const key = columnForTaskState(t.state);
    if (!groups[key]) groups[key] = [];
    groups[key].push(t);
  }
  for (const key of Object.keys(groups)) {
    groups[key] = sortTasksByDate(groups[key], TASK_COLUMN_SORT_DESCEND[key]);
  }
  return groups;
}
```

- [ ] **Step 4: Run tests to verify they pass**

Run: `node --test web/test/tasks-board.test.mjs`
Expected: PASS, all 9 tests.

- [ ] **Step 5: Commit**

```bash
git add web/app.js web/test/tasks-board.test.mjs
git commit -m "feat(web): add Tasks board column model (TASK_COLUMNS, columnForTaskState, groupTasksByColumn)"
```

## Task 2: Fix pre-existing failing default-tab tests

**Files:**
- Modify: `web/test/tab-persistence.test.mjs`

**Interfaces:**
- Consumes: `getActiveMainTab()` (existing, returns `'stories'` by default per `cc6b323`) — no production code change in this task, test-only fix.

- [ ] **Step 1: Confirm the current failure**

Run: `node --test web/test/tab-persistence.test.mjs`
Expected: FAIL — 2 of 6 tests fail (`'returns "queue" when localStorage has no stored value'` and `'returns "queue" after localStorage value is removed'`), asserting a default that no longer matches `getActiveMainTab()`'s actual `'stories'` default (changed in commit `cc6b323`, test never updated).

- [ ] **Step 2: Fix the two stale assertions**

In `web/test/tab-persistence.test.mjs`, change:

```js
  it('returns "queue" when localStorage has no stored value', () => {
    assert.equal(getActiveMainTab(), 'queue');
  });
```

to:

```js
  it('returns "stories" when localStorage has no stored value', () => {
    assert.equal(getActiveMainTab(), 'stories');
  });
```

and change:

```js
  it('returns "queue" after localStorage value is removed', () => {
    setActiveMainTab('stats');
    localStorage.removeItem('activeMainTab');
    assert.equal(getActiveMainTab(), 'queue');
  });
```

to:

```js
  it('returns "stories" after localStorage value is removed', () => {
    setActiveMainTab('stats');
    localStorage.removeItem('activeMainTab');
    assert.equal(getActiveMainTab(), 'stories');
  });
```

- [ ] **Step 3: Run tests to verify they pass**

Run: `node --test web/test/tab-persistence.test.mjs`
Expected: PASS, all 6 tests.

- [ ] **Step 4: Commit**

```bash
git add web/test/tab-persistence.test.mjs
git commit -m "test(web): fix stale default-tab assertions (queue -> stories, per cc6b323)"
```

---

## Task 3: Nav entry point — `index.html` + CSS

**Files:**
- Modify: `web/index.html`
- Modify: `web/style.css`

**Interfaces:**
- Produces: `<div data-panel="tasks">` container with a `.tasks-board` child, and a `[data-tab="tasks"]` nav button — consumed by Task 7's `renderTasksBoard`, and by the existing generic `switchTab`/`renderActiveTab` dispatch (no changes needed there beyond Task 7's new `case`, since both are already driven generically by `data-tab`/`data-panel` attributes).

This task is structural markup/CSS, not logic — there is no meaningful unit test for static HTML/CSS in this codebase's existing conventions (no other `data-panel` container has a dedicated test). Verify visually per Step 3.

- [ ] **Step 1: Add the nav button and panel container**

In `web/index.html`, change:

```html
  <nav class="tab-bar">
    <button class="tab active" data-tab="stories" title="Tracker">📋</button>
    <button class="tab" data-tab="stats" title="Model Dashboard">📊</button>
    <button class="tab" data-tab="drops" title="Drops">📁</button>
    <button class="tab" data-tab="settings" title="Settings">⚙️</button>
  </nav>
```

to:

```html
  <nav class="tab-bar">
    <button class="tab active" data-tab="stories" title="Tracker">📋</button>
    <button class="tab" data-tab="tasks" title="Tasks">📝</button>
    <button class="tab" data-tab="stats" title="Model Dashboard">📊</button>
    <button class="tab" data-tab="drops" title="Drops">📁</button>
    <button class="tab" data-tab="settings" title="Settings">⚙️</button>
  </nav>
```

And change:

```html
    <div data-panel="drops" hidden>
      <div class="drops-panel"></div>
    </div>
```

to (adding the new panel directly before the `drops` panel):

```html
    <div data-panel="tasks" hidden>
      <div class="tasks-board"></div>
    </div>
    <div data-panel="drops" hidden>
      <div class="drops-panel"></div>
    </div>
```

- [ ] **Step 2: Add CSS**

In `web/style.css`, directly after the `.stories-column-list` rule block (ends `overflow-y: auto;\n}` around line 2163, right before the `.story-card { cursor: grab; }` rule), add:

```css
.tasks-board {
  display: flex;
  align-items: flex-start;
  gap: 0.75rem;
  overflow-x: auto;
  padding-bottom: 0.5rem;
}

.tasks-column {
  flex: 0 0 220px;
  width: 220px;
  background: var(--bg);
  border: 1px solid var(--border);
  border-radius: 0.5rem;
  padding: 0.625rem;
  display: flex;
  flex-direction: column;
  gap: 0.5rem;
}

.tasks-column-header {
  display: flex;
  align-items: baseline;
  justify-content: space-between;
  font-size: 0.75rem;
  font-weight: 700;
  text-transform: uppercase;
  letter-spacing: 0.03em;
  color: var(--text-muted);
  padding-bottom: 0.4rem;
  border-bottom: 1px solid var(--border);
}

.tasks-column-count {
  font-weight: 700;
  color: var(--text);
  background: var(--surface);
  border-radius: 999px;
  padding: 0 0.45em;
  font-size: 0.7rem;
}

.tasks-column-list {
  display: flex;
  flex-direction: column;
  gap: 0.5rem;
  min-height: 40px;
  max-height: 70vh;
  overflow-y: auto;
}

.task-log-tail {
  background: var(--bg-card);
  border: 1px solid var(--border);
  border-radius: 6px;
  padding: 0.5rem 0.625rem;
  font-family: monospace;
  font-size: 0.75rem;
  max-height: 90px;
  overflow-y: auto;
  white-space: pre-wrap;
  word-break: break-word;
}

.task-log-tail-placeholder {
  color: var(--text-muted);
  font-size: 0.8rem;
  font-style: italic;
}
```

- [ ] **Step 3: Verify visually**

Run the claudomator server locally (or check the already-running production instance after deploy), navigate to the dashboard, and confirm:
- A new "Tasks" (📝) button appears in the nav between Tracker and Model Dashboard.
- Clicking it shows an empty `.tasks-board` container (no columns yet — those render starting in Task 7; this is expected at this point in the plan).

- [ ] **Step 4: Commit**

```bash
git add web/index.html web/style.css
git commit -m "feat(web): add Tasks nav tab entry point + board/column/log-tail CSS"
```

## Task 4: Extend `createTaskCard` — DI `doc` param, log-tail placeholder, elapsed timer

**Files:**
- Modify: `web/app.js` (`createTaskCard`, ~line 278)
- Test: `web/test/tasks-board.test.mjs` (append)

**Interfaces:**
- Consumes: nothing new.
- Produces: `createTaskCard(task, doc = document)` (added `doc` param, default preserves existing callers' behavior unchanged); every returned card now has a stable child element findable via `card.querySelector('.task-log-tail, .task-log-tail-placeholder')` for non-terminal-vs-Queue distinction, and RUNNING cards additionally have `card.querySelector('.task-elapsed[data-started-at]')`. Consumed by Task 5 (diff-preserving render) and Task 6 (log-stream attachment).

- [ ] **Step 1: Write the failing tests**

Append to `web/test/tasks-board.test.mjs`:

```js
// ── createTaskCard: log-tail placeholder + elapsed timer ────────────────────
//
// createTaskCard uses the real global `document` by default (existing
// convention throughout app.js — e.g. renderEventTimeline(events, doc =
// document)) but accepts an injectable `doc` for Node-based unit testing
// without jsdom, matching the hand-rolled mock-DOM convention already used
// by web/test/task-panel-summary.test.mjs and web/test/render-dedup.test.mjs.

import { createTaskCard } from '../app.js';

function makeMockDoc() {
  function makeEl(tag) {
    return {

        toggle(cls, on) { on ? this._set.add(cls) : this._set.delete(cls); },
        contains(cls) { return this._set.has(cls); },
      },
      textContent: '',
      title: '',
      hidden: false,
      dataset: {},
      children: [],
      _listeners: {},
      appendChild(child) { this.children.push(child); return child; },
      append(...nodes) { nodes.forEach(n => this.children.push(n)); },
      prepend(...nodes) { this.children.unshift(...nodes); },
      addEventListener(type, fn) { this._listeners[type] = fn; },
      querySelector(sel) {
        const cls = sel.split(',')[0].trim().replace(/^\./, '');
        const search = (el) => {
          if (el.className && el.className.split(' ').includes(cls)) return el;
          if (el.dataset && sel.includes('[data-started-at]') && el.className.includes('task-elapsed') && 'startedAt' in el.dataset) return el;
          for (const c of el.children) {
            const found = search(c);
            if (found) return found;
          }
          return null;
        };
        return search(this);
      },
    };
  }
  return { createElement: (tag) => makeEl(tag) };
}

describe('createTaskCard log-tail placeholder', () => {

      const card = createTaskCard({ id: 't1', name: 'Task', state }, doc);
      const placeholder = card.querySelector('.task-log-tail-placeholder');
      const tail = card.querySelector('.task-log-tail');

    assert.ok(running.querySelector('.task-elapsed[data-started-at]'));

    const ready = createTaskCard({ id: 't2', name: 'Task', state: 'READY' }, doc);
    assert.equal(ready.querySelector('.task-elapsed[data-started-at]'), null);
  });
});
```

- [ ] **Step 2: Run tests to verify they fail**

Run: `node --test web/test/tasks-board.test.mjs`
Expected: FAIL — `createTaskCard` is not exported from `../app.js` yet, and even once exported, the log-tail/elapsed-timer elements don't exist yet.

- [ ] **Step 3: Implement**

In `web/app.js`, change the `createTaskCard` function signature and body. First, make it exported and accept `doc`:

Change:
```js
function createTaskCard(task) {
  const card = document.createElement('div');
```
to:
```js
export function createTaskCard(task, doc = document) {
  const card = doc.createElement('div');
```

Then replace every other bare `document.createElement(...)` call *inside* `createTaskCard` (there are several: `header`, `name`, `badge`, `meta`, `prio`, `when`, `proj`, `desc`, `errEl`, `reportEl`/`label`/`text`, `footer`, buttons, `delBtn`) with `doc.createElement(...)`. This is a mechanical find-and-replace scoped to this one function only — do not touch `document.createElement` calls in other functions.

Next, add the log-tail placeholder and elapsed timer. Immediately after the "Meta: priority + created_at" block (after `if (meta.children.length) card.appendChild(meta);`) and before the "Description (truncated via CSS)" block, insert:

```js
  // Elapsed timer for RUNNING tasks (no separate ticking interval — updated
  // on each poll tick alongside the rest of the board, same convention the
  // old Running-tab card used).
  if (task.state === 'RUNNING') {
    const elapsed = doc.createElement('span');
    elapsed.className = 'task-elapsed running-elapsed';
    elapsed.dataset.startedAt = task.updated_at ?? '';
    elapsed.textContent = formatElapsed(task.updated_at);
    card.appendChild(elapsed);
  }
```

Then, immediately before the footer block (before the line `const RESUME_STATES  = new Set(['TIMED_OUT', 'CANCELLED', 'FAILED', 'BUDGET_EXCEEDED']);`), insert the log-tail placeholder/element:

```js
  // Inline log tail (no click required) — see docs/superpowers/specs/2026-07-06-tasks-board-design.md
  // section 4. PENDING/QUEUED tasks have no execution row yet, so there is
  // nothing to tail; every other state gets a .task-log-tail element that
  // Task 6's ensureTaskLogStream() attaches an SSE stream to.
  if (task.state === 'PENDING' || task.state === 'QUEUED') {
    const placeholder = doc.createElement('div');
    placeholder.className = 'task-log-tail-placeholder';
    placeholder.textContent = 'Waiting to start…';
    card.appendChild(placeholder);
  } else {
    const logTail = doc.createElement('div');
    logTail.className = task.state === 'RUNNING' || task.state === 'BLOCKED'
      ? 'task-log-tail running-log'
      : 'task-log-tail';
    logTail.dataset.logTarget = task.id;
    card.appendChild(logTail);
  }
```

- [ ] **Step 4: Run tests to verify they pass**

Run: `node --test web/test/tasks-board.test.mjs`
Expected: PASS, all tests including the new ones.

- [ ] **Step 5: Run the full existing suite to check for regressions**

Run: `node --test web/test/*.test.mjs`
Expected: PASS for everything except the 2 pre-existing `tab-persistence.test.mjs` failures already fixed in Task 2 (so: full pass at this point). `render-dedup.test.mjs` uses its own separate inline mock (not the real `createTaskCard`), so it is unaffected by this change.

git add web/app.js web/test/tasks-board.test.mjs
git commit -m "feat(web): createTaskCard - inject doc param, add log-tail placeholder + elapsed timer"

## Task 5: Diff-preserving render — protect live log-tail content across re-renders

**Files:**
- Modify: `web/app.js` (`renderTasksIntoContainer`, ~line 718)
- Test: `web/test/tasks-board.test.mjs` (append)

**Interfaces:**
- Consumes: `createTaskCard` (Task 4).
- Produces: `cardContentSignature(cardEl)` (exported for testing) and a modified `renderTasksIntoContainer` that no longer tears down a card's `.task-log-tail`/`.running-log` subtree when nothing else about the card changed, and transplants the existing (already-streaming) log-tail element across a replace when something else *did* change. Consumed by Task 6 (so a live `EventSource`'s target element survives poll-driven re-renders) and Task 7.

**Why this task exists:** `renderTasksIntoContainer` currently does `if (card.innerHTML !== newCard.innerHTML) { container.replaceChild(newCard, card); }`. Once cards contain a log-tail that accumulates streamed lines (Task 6), `card.innerHTML` changes on essentially every poll tick even when nothing else changed, causing a full teardown-and-rebuild — which would close and reopen the `EventSource` connection repeatedly (flicker, wasted reconnects, lost partial output). This task fixes that by excluding the log-tail subtree from the comparison and preserving the real (streaming) DOM node across any replace that does occur.

- [ ] **Step 1: Write the failing tests**

Append to `web/test/tasks-board.test.mjs`:

```js
// ── renderTasksIntoContainer: log-tail preservation across re-renders ──────

import { cardContentSignature } from '../app.js';

describe('cardContentSignature', () => {
  it('excludes .task-log-tail content from the signature', () => {
    const doc = makeMockDoc();
    const cardA = createTaskCard({ id: 't1', name: 'Task', state: 'READY' }, doc);
    const cardB = createTaskCard({ id: 't1', name: 'Task', state: 'READY' }, doc);
    // Simulate cardB having accumulated live log lines that cardA (freshly built) doesn't have.
    const tailB = cardB.querySelector('.task-log-tail');
    tailB.children.push({ tag: 'div', className: 'log-line', textContent: 'some streamed output', children: [] });
    assert.equal(cardContentSignature(cardA), cardContentSignature(cardB));
  });

  it('still differs when a non-log field changes', () => {
    const doc = makeMockDoc();
    const cardA = createTaskCard({ id: 't1', name: 'Task', state: 'READY' }, doc);
    const cardB = createTaskCard({ id: 't1', name: 'Task', state: 'FAILED' }, doc);
    assert.notEqual(cardContentSignature(cardA), cardContentSignature(cardB));
  });
});
```

- [ ] **Step 2: Run tests to verify they fail**

Run: `node --test web/test/tasks-board.test.mjs`
Expected: FAIL — `cardContentSignature` is not exported yet. (Note: the mock DOM's `querySelector`/`children` handling needs a `serialize`-style read for the signature to work meaningfully in the test; the implementation step below defines `cardContentSignature` to walk `.children`/`.className`/`.textContent` recursively rather than relying on a real `innerHTML` getter, since the hand-rolled mock has no `innerHTML`. This keeps the function testable without jsdom.)

- [ ] **Step 3: Implement**

In `web/app.js`, add `cardContentSignature` directly before `renderTasksIntoContainer`:

```js
// cardContentSignature returns a structural fingerprint of a task card,
// excluding any .task-log-tail/.running-log subtree — live-streamed log
// content must never cause renderTasksIntoContainer to think the card
// "changed" and tear it down (see Task 5 of the tasks-board plan).
export function cardContentSignature(cardEl) {
  function walk(el) {
    if (!el) return '';
    const isLogTail = el.className && (
      el.className.split(' ').includes('task-log-tail') ||
      el.className.split(' ').includes('running-log')
    );
    if (isLogTail) return `<logtail:${el.dataset && el.dataset.logTarget || ''}>`;
    const childSig = (el.children || []).map(walk).join('');
    return `<${el.tag || ''} class="${el.className || ''}" data-state="${(el.dataset && el.dataset.state) || ''}">${el.textContent || ''}${childSig}`;
  }
  return walk(cardEl);
}
```

Then change `renderTasksIntoContainer`'s update branch. Replace:

```js
    if (card) {
      // If the content is exactly the same, we could skip replacing,
      // but createTaskCard is fast and ensures we have the latest state.
      // We replace the card in-place to preserve its position if possible.
      if (card.innerHTML !== newCard.innerHTML) {
        // Special case: if user is interacting with THIS card, we might want to skip or merge.
        // For now, createTaskCard ensures we don't disrupt if NOT editing.
        container.replaceChild(newCard, card);
      }
    } else {
      // Append new card
      container.appendChild(newCard);
    }
```

with:

```js
    if (card) {
      // Compare everything except live-streamed log content (see
      // cardContentSignature) so an appending .task-log-tail never triggers
      // a teardown-and-rebuild of the whole card on its own.
      if (cardContentSignature(card) !== cardContentSignature(newCard)) {
        // Preserve the existing (potentially already-streaming) log-tail
        // element across the swap so its EventSource's target node stays
        // attached and its accumulated content survives.
        const oldLogTail = card.querySelector('.task-log-tail');
        const newLogTail = newCard.querySelector('.task-log-tail');
        if (oldLogTail && newLogTail) newLogTail.replaceWith(oldLogTail);
        container.replaceChild(newCard, card);
      }
    } else {
      // Append new card
      container.appendChild(newCard);
    }
```

- [ ] **Step 4: Run tests to verify they pass**

Run: `node --test web/test/tasks-board.test.mjs`
Expected: PASS, all tests.

- [ ] **Step 5: Run the full existing suite to check for regressions**

Run: `node --test web/test/*.test.mjs`
Expected: PASS for everything. `render-dedup.test.mjs` tests a separate inline-mocked contract for the *removal/dedup* behavior of `renderTasksIntoContainer`, not the `innerHTML`-vs-signature comparison itself, so it is unaffected — confirm this by reading its assertions if any failure appears here (do not silently ignore a failure).

- [ ] **Step 6: Commit**

```bash
git add web/app.js web/test/tasks-board.test.mjs
git commit -m "fix(web): exclude live log-tail content from card re-render diffing"
```

## Task 6: Generalized log-tail streaming — `ensureTaskLogStream`

**Files:**
- Modify: `web/app.js` (add new function; remove `startRunningLogStream`, `runningViewLogSources`, old `updateRunningElapsed` — removal happens in Task 8, not here, to avoid breaking `renderRunningView` before it's removed)
- Test: `web/test/tasks-board.test.mjs` (append)

**Interfaces:**
- Consumes: `card.querySelector('.task-log-tail, .running-log')` elements from Task 4/5.
- Produces: `ensureTaskLogStream(taskId, logAreaEl, opts)` where `opts = { fetchFn = fetch, EventSourceImpl = (typeof EventSource !== 'undefined' ? EventSource : undefined), apiBase = API_BASE } = {}`. Also produces the module-level `taskLogStreams` map (`{ [taskId]: { source, execId } }`). Consumed by Task 7 (`renderTasksBoard` calls this once per visible card after each render pass) and Task 8 (removal target for the old equivalents).

**Design note (from the approved spec):** `/api/executions/{id}/logs/stream` already replays-then-closes for a terminal execution and live-tails for a RUNNING one — the *same* function works for every column. The one thing `ensureTaskLogStream` must get right: don't reopen a stream for an execution it's already attached to (checked via the tracked `execId`), and do close+reopen when the task's latest execution ID has changed (e.g. a Resume/Restart produced a new execution).

- [ ] **Step 1: Write the failing tests**

Append to `web/test/tasks-board.test.mjs`:

```js
// ── ensureTaskLogStream: stream lifecycle (reuse vs. reopen vs. no-op) ─────

import { ensureTaskLogStream, taskLogStreams } from '../app.js';

    removeChild(c) { this.children = this.children.filter(x => x !== c); },
    get childElementCount() { return this.children.length; },
    get firstElementChild() { return this.children[0]; },
    get innerHTML() { return ''; },
    set innerHTML(_) { this.children = []; }, // mirrors real DOM: assigning innerHTML clears children
    scrollTop: 0, scrollHeight: 0, clientHeight: 0, addEventListener() {},
  };
}

    assert.equal(FakeES.instances.length, 1);
    assert.match(FakeES.instances[0].url, /\/api\/executions\/exec-1\/logs\/stream/);

    assert.equal(taskLogStreams['task-3'].execId, 'exec-b');
  });
});
```

- [ ] **Step 2: Run tests to verify they fail**

Run: `node --test web/test/tasks-board.test.mjs`
Expected: FAIL — `ensureTaskLogStream`/`taskLogStreams` not exported yet.

- [ ] **Step 3: Implement**

In `web/app.js`, add directly after the (soon-to-be-removed-in-Task-8, but for now still present) `runningViewLogSources` declaration — actually, to keep this task's diff self-contained and not depend on Task 8's removal, add the new code as a distinct block right before the existing `function startRunningLogStream(taskId, logArea) {` definition:

```js
// taskId -> { source: EventSource, execId: string } — tracks which execution
// each visible task's inline log-tail is currently attached to, so a poll-
// driven re-render never reopens a stream for the same execution twice, and
// correctly reopens when a Resume/Restart produces a fresh execution.
export const taskLogStreams = {};

// ensureTaskLogStream attaches (or leaves alone) a log stream for a task's
// most recent execution into logAreaEl. Every column's card uses this same
// mechanism — see docs/superpowers/specs/2026-07-06-tasks-board-design.md
// section 4: the /api/executions/{id}/logs/stream endpoint already replays-
// then-closes for a terminal execution and live-tails for a RUNNING one, so
// there is no separate "static" vs. "live" code path.
export async function ensureTaskLogStream(taskId, logAreaEl, {
  fetchFn = fetch,
  EventSourceImpl = (typeof EventSource !== 'undefined' ? EventSource : undefined),
  apiBase = API_BASE,
} = {}) {
  let execs;
  try {
    const res = await fetchFn(`${apiBase}/api/executions?task_id=${taskId}&limit=1`);
    execs = res.ok ? await res.json() : [];
  } catch {
    return;
  }
  if (!execs || execs.length === 0) return; // no execution yet (Queue)

  const execId = execs[0].id;
  const existing = taskLogStreams[taskId];
  if (existing && existing.execId === execId) return; // already attached to this execution

  if (existing) existing.source.close();
  // .children is a read-only live collection on a real DOM element — the
  // only correct way to clear it is innerHTML (the fake log-area mock in
  // web/test/tasks-board.test.mjs mirrors this via an innerHTML setter).
  logAreaEl.innerHTML = '';

  const src = new EventSourceImpl(`${apiBase}/api/executions/${execId}/logs/stream`);
  taskLogStreams[taskId] = { source: src, execId };

  let userScrolled = false;
  if (logAreaEl.addEventListener) {
    logAreaEl.addEventListener('scroll', () => {
      const nearBottom = logAreaEl.scrollHeight - logAreaEl.scrollTop - logAreaEl.clientHeight < 50;
      userScrolled = !nearBottom;
    });
  }

  src.onmessage = (event) => {
    let data;
    try { data = JSON.parse(event.data); } catch { return; }

    const doc = (typeof document !== 'undefined') ? document : { createElement: (t) => ({ tag: t, className: '', textContent: '', children: [], appendChild(c) { this.children.push(c); } }) };
    const line = doc.createElement('div');
    line.className = 'log-line';

    switch (data.type) {
      case 'text':
        line.classList.add('log-text');
        line.textContent = data.text ?? data.content ?? '';
        break;
      case 'tool_use': {
        line.classList.add('log-tool-use');
        const toolName = doc.createElement('span');
        toolName.className = 'tool-name';
        toolName.textContent = `[${data.name ?? 'Tool'}]`;
        line.appendChild(toolName);
        const inputStr = data.input ? JSON.stringify(data.input) : '';
        const inputPreview = doc.createElement('span');
        inputPreview.textContent = ' ' + inputStr.slice(0, 120);
        line.appendChild(inputPreview);
        break;
      }
      case 'cost':
        line.classList.add('log-cost');
        line.textContent = `Cost: $${Number(data.total_cost ?? data.cost ?? 0).toFixed(3)}`;
        break;
      default:
        return;
    }

    logAreaEl.appendChild(line);
    while (logAreaEl.childElementCount > 200) {
      logAreaEl.removeChild(logAreaEl.firstElementChild);
    }
    if (!userScrolled) logAreaEl.scrollTop = logAreaEl.scrollHeight;
  };

  src.addEventListener('done', () => {
    src.close();
    if (taskLogStreams[taskId] && taskLogStreams[taskId].source === src) delete taskLogStreams[taskId];
  });

  src.onerror = () => {
    src.close();
    if (taskLogStreams[taskId] && taskLogStreams[taskId].source === src) delete taskLogStreams[taskId];
  };
}
```

Note: the 500-line trim used by the old `startRunningLogStream` is reduced to 200 here, since compact `.task-log-tail` cards are ~90px tall (a handful of visible lines) — 200 is still generous headroom and avoids unbounded memory growth for a long-running task's card sitting open for hours.

## Task 7: `renderTasksBoard` + wire into `renderActiveTab`

**Files:**
- Modify: `web/app.js` (add `renderTasksBoard`; modify `renderActiveTab`)

**Interfaces:**
- Consumes: `groupTasksByColumn` (Task 1), `TASK_COLUMNS` (Task 1), `renderTasksIntoContainer` (Task 5, already modified), `ensureTaskLogStream` (Task 6).
- Produces: `renderTasksBoard(tasks, container)`, wired into `renderActiveTab`'s `case 'tasks':`.

- [ ] **Step 1: Implement** (no new unit test for this step — it's DOM orchestration glue over already-tested pure functions; verified via Step 2's manual smoke test, matching this codebase's existing convention of not unit-testing top-level `render*Panel` orchestration functions)

In `web/app.js`, add directly after `renderStoriesBoard`'s closing brace (before the `// ── Stories tab: epic swimlanes` comment):

```js
// ── Tasks tab: unified board ─────────────────────────────────────────────────

function renderTasksBoard(tasks, container) {
  const groups = groupTasksByColumn(tasks);
  let board = container.querySelector('.tasks-board');
  if (!board) {
    board = document.createElement('div');
    board.className = 'tasks-board';
    container.appendChild(board);
  }

  for (const col of TASK_COLUMNS) {
    let colEl = board.querySelector(`[data-column-key="${col.key}"]`);
    if (!colEl) {
      colEl = document.createElement('div');
      colEl.className = 'tasks-column';
      colEl.dataset.columnKey = col.key;

      const header = document.createElement('div');
      header.className = 'tasks-column-header';
      const title = document.createElement('span');
      title.textContent = col.label;
      const count = document.createElement('span');
      count.className = 'tasks-column-count';
      header.append(title, count);
      colEl.appendChild(header);

      const list = document.createElement('div');
      list.className = 'tasks-column-list';
      colEl.appendChild(list);

      board.appendChild(colEl);
    }

    const countEl = colEl.querySelector('.tasks-column-count');
    countEl.textContent = String(groups[col.key].length);

    const list = colEl.querySelector('.tasks-column-list');
    renderTasksIntoContainer(groups[col.key], list, `No tasks in ${col.label.toLowerCase()}.`);
  }

  // Attach/refresh the inline log tail for every visible card that has one
  // (createTaskCard omits it for PENDING/QUEUED — see Task 4).
  board.querySelectorAll('.task-log-tail').forEach((logArea) => {
    const taskId = logArea.dataset.logTarget;
    if (taskId) ensureTaskLogStream(taskId, logArea);
  });

  // Elapsed timers update on every poll tick (same convention the old
  // Running-tab card used — no separate ticking interval).
  board.querySelectorAll('.task-elapsed[data-started-at]').forEach((el) => {
    el.textContent = formatElapsed(el.dataset.startedAt || null);
  });
}
```

Then, in `renderActiveTab`'s switch, add a `case 'tasks':` branch. Change:

```js
function renderActiveTab(allTasks) {
  const activeTab = getActiveTab();
  switch (activeTab) {
    case 'stories':
      // Guard against yanking the board out from under an in-progress
      // HTML5 drag (see draggingStoryId) — the next poll tick after the
      // drag ends will pick up any server-side change.
      if (!draggingStoryId) renderStoriesPanel();
      break;
```

to:

```js
function renderActiveTab(allTasks) {
  const activeTab = getActiveTab();
  switch (activeTab) {
    case 'stories':
      // Guard against yanking the board out from under an in-progress
      // HTML5 drag (see draggingStoryId) — the next poll tick after the
      // drag ends will pick up any server-side change.
      if (!draggingStoryId) renderStoriesPanel();
      break;
    case 'tasks': {
      const panel = document.querySelector('[data-panel="tasks"]');
      if (panel) renderTasksBoard(allTasks, panel);
      break;
    }
```

- [ ] **Step 2: Manual smoke test**

Run the claudomator dev server, log in, click the new Tasks (📝) tab. Confirm:
- 5 columns render: Queue, Running, Ready, Interrupted, Done, each with a count badge.
- Submit a test task via the chatbot MCP (or `POST /api/tasks` + `/run`) and watch it move Queue → Running → Ready/Interrupted/Done across poll ticks without the page needing a manual refresh.
- While a task is RUNNING, confirm its card shows live-appending log lines with no click required.
- Click a card in any column — confirm the existing side panel (`openTaskPanel`) still opens with full detail, unaffected by this change.

- [ ] **Step 3: Run the full existing suite to check for regressions**

Run: `node --test web/test/*.test.mjs`
Expected: PASS for everything.

- [ ] **Step 4: Commit**

```bash
git add web/app.js
git commit -m "feat(web): add renderTasksBoard, wire Tasks tab into renderActiveTab"
```

## Task 8: Remove superseded dead code

**Files:**
- Modify: `web/app.js`

**Interfaces:** none — pure removal of code with zero remaining callers after Tasks 1–7.

**Explicitly NOT removed** (per Global Constraints above): `renderRunningHistory`, `sortExecutionsByDate`/`sortExecutionsDesc`, `fetchRecentExecutions` (separate system-wide execution-history feature, not superseded by this board); `filterQueueTasks`, `filterReadyTasks`, `filterAllDoneTasks`, `filterTasksByTab`, `filterActiveTasks`, `filterTasks` and their test files (pre-existing unrelated dead code, out of scope).

- [ ] **Step 1: Confirm zero remaining callers before deleting anything**

Run each of these and confirm the count matches "definition only" (no other callers), to guard against deleting something Task 7 turned out to still need:

```bash
grep -c '\brenderQueuePanel\b' web/app.js        # expect 1
grep -c '\brenderInterruptedPanel\b' web/app.js  # expect 1
grep -c '\brenderReadyPanel\b' web/app.js        # expect 1
grep -c '\brenderRunningView\b' web/app.js       # expect 1
grep -c '\bisRunningTabActive\b' web/app.js      # expect 1
grep -c '\brunningViewLogSources\b' web/app.js   # expect exactly the definition + internal uses within startRunningLogStream/renderRunningView (all being deleted together)
```

If any count is higher than expected, stop and investigate the extra caller before proceeding — do not delete a function something else still depends on.

- [ ] **Step 2: Delete `renderQueuePanel`, `renderInterruptedPanel`, `renderReadyPanel`**

In `web/app.js`, delete these three function definitions in full (each superseded by `renderTasksBoard`'s Queue/Interrupted/Ready columns):

```js

and (further down) the full `renderReadyPanel` function (from `function renderReadyPanel(tasks) {` through its closing `}`, the version shown in Task investigation that renders both the ready list and the `ready-completed-history` sub-section).

- [ ] **Step 3: Delete `renderRunningView`, `isRunningTabActive`, old `startRunningLogStream`, `runningViewLogSources`, old `updateRunningElapsed`**

Delete, in full:
- The `runningViewLogSources` map declaration (`const runningViewLogSources = {};` and its preceding comment).
- The entire `function renderRunningView(tasks) { ... }` body.
- The entire old `function startRunningLogStream(taskId, logArea) { ... }` body (superseded by `ensureTaskLogStream` from Task 6 — this is the version that referenced `runningViewLogSources` and hardcoded a 500-line trim; the new `ensureTaskLogStream` added in Task 6 is a separate, already-exported function and is unaffected by this deletion).
- The entire `function updateRunningElapsed() { ... }` body (superseded by the inline elapsed-timer update loop added directly in `renderTasksBoard`, Task 7).
- The entire `function isRunningTabActive() { ... }` body.

- [ ] **Step 4: Run the full test suite**

Run: `node --test web/test/*.test.mjs`
Expected: PASS for everything (no test file imported any of the deleted functions by name — confirmed during plan research; `running-view.test.mjs` tests an inline-duplicated `filterRunningTasks`/`formatElapsed`/`extractLogLines`, not the real functions, and is untouched).

- [ ] **Step 5: Run `go build`/`go test` as a final safety check**

Run: `go build ./... && go test ./...`
Expected: PASS — this plan makes no Go changes, but this confirms nothing else in the repo was inadvertently affected.

- [ ] **Step 6: Commit**

```bash
git add web/app.js
git commit -m "chore(web): remove queue/interrupted/ready/running panel code superseded by the unified Tasks board"
```

---

## Final Verification

- [ ] Run `node --test web/test/*.test.mjs` — full suite passes.
- [ ] Run `go build ./... && go test ./...` — passes (no Go changes expected, this is a safety net).
- [ ] Manual smoke test (repeat Task 7 Step 2) against the deployed instance after rollout: submit a real task via chatbot MCP, watch it traverse Queue → Running → Ready/Done on the board with live log output, with zero clicks required to see it happening.
