As the user types, a subsequence-scored fuzzy match against `BOOK_ALIASES` (~130 entries) produces up to 5 ranked suggestions rendered under the input. `↑`/`↓` navigates the list (clamped at edges; no wrap); selected row uses the accent color matching the verse cursor pattern. `Tab` accepts the selected suggestion — rewrites the input to `{DisplayName} ` (with trailing space, ready for chapter typing) and clears the list. `Enter` always submits the query as-typed, no ambiguity with suggestion selection. Driver's `awaiting`-state gate is split to allow `up`/`down`/`tab` through while suppressing everything else (except `q`/`Q` quit, which sits above the gate). New pure domain module `src/domain/book-suggestions.ts` with subsequence + light-scoring algorithm (exact-match, prefix, density bonuses); display names derived from longest alias per USFM code with regex transform for numbered books. 178/178 tests pass. + +--- + +## Branch Status + +**Branch**: `feat/palette-suggestions` +**Commits**: 5 — 3 from the original SDD apply, the SDD-trail/verify-report commit, then one post-verify bug fix from manual smoke. +**Working tree**: clean, ready to push. + +### Commit Log + +| # | SHA | Message | +|---|---|---| +| 1 | `04c9716` | feat(domain): book-suggestions module with subsequence-scored fuzzy match | +| 2 | `c904299` | feat(tui): reader-reducer awaiting state gains suggestion fields | +| 3 | `8556f03` | feat(tui): suggestion list view + driver gate split for navigation keys | +| 4 | `e0051ff` | docs(openspec): add SDD trail + verify report for palette-suggestions | +| 5 | `9d5b4df` | fix(tui): use onInput for per-keystroke palette updates | + +--- + +## Verification Summary + +**Initial SDD verify verdict**: PASS WITH WARNINGS (16/16 REQs satisfied) +**Tests**: 178/178 pass +**tsc --noEmit**: exits 0 +**Critical**: 0 | **Warning**: 2 (test count gap vs target — non-blocking; no driver/view automated tests — by design) | **Suggestion**: 2 (cosmetic) + +### Post-verify sanctioned fix (commit 5) + +Manual PTY smoke revealed suggestions never appeared while typing. Root cause: OpenTUI's `` follows DOM semantics — `onChange` fires on commit/blur, NOT per keystroke. The reader was wired to `onChange`, so `state.query` only updated when `onSubmit` fired on Enter (which races just in time for `QuerySubmitted` to read the final value). During typing, `state.query` was perpetually empty, so `suggestBooks` returned `[]` every render. + +One-line fix: `onChange` → `onInput`. `onInput` is OpenTUI's per-keystroke event. `QueryTyped` now dispatches on every character, suggestions populate live, list renders correctly. + +This bug was latent in PR #10 and #11 as well — the reader still worked because `onChange` fires just before `onSubmit` on Enter, so the final value landed in `state.query` in time. But during typing, state lagged.
