Plan for the first Handwired book: five chapters covering every experiment in chenglou/handwired lab/ at 4ea7fcb. Includes the per-lab digests it cites and a README with status and resume steps. No scenes, narration or cover yet. Planned with claude-sonnet-5-5 (only model used per run record). Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>

| **Mechanism:** `lab/hard-attend/hard-attend.ts` is plain browser JavaScript, "not a numeric program". There are three items (Aster=10, Banyan=20, Cobalt=30). `keyFor(j)` returns `(2j, -j²)` and the query is `(query, 1)`, so `scoreFor` gives `2·query·j − j²`. This parabola peaks at the item nearest the query. `winnerIndexFor` takes the first highest score (strict `>`, so ties stay left). `update()` computes three reads: the one-hot gather (bits times values, summed), the direct gather `values[winner]` (labelled `hardAttend` on the page), and `softmax(scores, beta)` times values. A query slider (0 to 2, step 0.01) and a "sharpness" beta slider (0.5 to 14) drive the page (`hard-attend.html:19-61`). | ||
|
|
||
| **Result:** No measured result. It is a teaching page, and "The folder has no tests." The page shows that the one-hot gather and the direct gather give the same value, and that the softmax read moves toward that value as sharpness rises. |

Qualify the softmax claim at exact score ties.
The hard selector keeps the left item when scores tie, but the softmax read does not converge to that item. At the reachable query 0.5, items 0 and 1 tie. The hard read returns 10, while increasing beta makes the softmax read approach 15, the average of 10 and 20.
Qualify all four descriptions to state that softmax approaches the hard-selected value away from exact ties. At an exact tie, state that it approaches the average of the tied top values.

Use repository-relative digest paths.
The assignment's required read step uses author-local paths. The README provides a relative digests/ pointer, so the workflow is not fully blocked. However, a planner following the assignment alone cannot resolve the required inputs.

Do not label 2.8 px as a median.
The caption says “a median 2.8 px,” but Line 93 states that 2.8 is the first table figure and is not identified as a median. Remove “median” or use the metric label from the source table.

The cited source does not establish “five coefficients.” Remove that phrase or cite the exact source line that states the coefficient count.

Review comment at @docs/book-plans/handwired-labs/review.md at line 89:
The review table entry for the user-effort lab should not claim “five
coefficients” unless an exact cited source line establishes that count. Remove
the phrase from the summary, or update the citation to the precise source line
if the coefficient count is documented there.
