Closes #394.

Pericope view now fills every empty verse in the active group, prefetches the next group, and adds a separate section-title input when the source has a title. Saved text and titles, including text typed while suggestions are still arriving, are preserved. Each displayed verse and title is logged immediately; prefetched groups are logged only when opened.

Turning AI off preserves visible drafts and stops new fills. Turning it on fills the active group's empty fields. The same behavior works in the rich text and textarea pericope editors. The title stays in markers.headings, outside scripture text, and uses the existing autosave pipeline.

The heading dependency #475 is now merged into main. This PR still requires eten-tech-foundation/fluent-api#326 and eten-tech-foundation/fluent-ai#74 before rollout. The API work is stacked on eten-tech-foundation/fluent-api#320 and adds a migration for heading suggestions and their exposure records.

Validation after merging the latest main: all 639 tests passed; typecheck, lint (no errors), format and diff checks passed. Browser checks used the real DraftingUI and editor for delayed suggestions, saved and locally edited text, title edits, navigation, AI off/on, both editor surfaces and autosave payloads.

End-to-end browser validation also passed through the real local API, PostgreSQL, queue and AI worker with a deterministic model provider: generated verses/title, immediate exposure, preserved authored content, and title autosave.

Screenshots

1) Pericope fill and separate title

A controlled local browser fixture shows suggestions in every empty verse after opening each group. The saved verse 2 remains unchanged, and the section title stays in its own input above scripture text.

Pericope suggestions fill empty verses while the separate section title and saved text remain visible

2) Preservation and autosave after reload

The real local browser → API → queue → worker → PostgreSQL fixture after autosave and reload. The edited title persists, generated verses 1–2 remain saved, verse 3 keeps its authored text and heading, and prefetched verse 4 is still empty until its group becomes active.

Saved pericope title, generated verses, authored content, and empty prefetched next group after reload

Explanation

Issue #394 requirements are implemented for active and prefetched pericopes, empty-field protection, titled pericopes, separate title tracking, toggle refill behavior, and automated coverage. One toggle case remains unmet. In useAiSuggestions, the queue effect continues when enabled is false if the context has no recorded threshold. In pericope mode, pericopeRequest is then false, so the effect posts to queue-next. This can start new suggestion work after AI is disabled, contrary to #394's requirement to stop loading suggestions for new pericopes.

Resolution

Return from the queue effect whenever AI is disabled for a pericope context, while preserving any required threshold state separately. Add a test that starts a pericope with AI disabled before the context threshold is recorded and verifies that no queue request occurs.

Both correctness bugs flagged in the previous review (title-clear re-arming AI fetch, lost backward-navigation queue guard) are fixed in ee17d1e via touchedTitleVerseNumbers and the reinstated lastQueuedVerseRef monotonic check. LGTM.

220-221: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Move the ref write out of render.

fetchHeadingsRef.current persists across renders, but the hook mutates it during render. If React discards that render, the queue continuation can later read the discarded value at fetchHeadingsRef.current and skip or perform refetchHeadings for the wrong committed state.

Declare the assignment effect before the queue effect. The assignment runs first when both effects respond to the same commit, so the newly scheduled queue effect does not read the previous value.

   const fetchHeadingsRef = useRef(fetchHeadings);
-  fetchHeadingsRef.current = fetchHeadings;
+  useEffect(() => {
+    fetchHeadingsRef.current = fetchHeadings;

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Match AI fill candidates by chapter and verse.

This condition ignores chapterNumber. If a cross-chapter pericope contains the same verse number in another chapter, the condition can include a current-chapter verse that is not in the current-chapter part of the pericope. The effect can then fill and log the wrong verse.

🟡 Minor · Reset resource Bible state when chapterAssignmentId changes. · DraftingUI.tsx:100-104

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reset resource Bible state when chapterAssignmentId changes. DraftingPage can replace projectItem while rendering the same DraftingUI instance because it does not provide an assignment-based key. React therefore preserves these states. The saved-state initialization effect also runs only once.

The retained activeBibleTabId selects a retained resourceBibleTabs entry, and bibleVerses reads that entry’s cached verses. DraftingChapterView consumes the retained tab and verse data, so the new assignment can display resource verses from the previous assignment. resourcePanelSelectedBibleId is also passed to the resource sidebar without being reset.

Add key={projectItem.chapterAssignmentId} to DraftingUI, or reset these three states when projectItem.chapterAssignmentId changes.

Reviewed the pericope suggestion flow. Four medium-severity observations below — all judgement calls, so take or leave them as you see fit. (I also have five low-severity notes I've left off the PR to keep the noise down; happy to add them if useful.)

A title-only fill re-saves an already-drafted verse, and logs it as an accepted verse suggestion.

This calls handleTextChange with firstTarget.content — the verse's existing content — purely to attach titleFill.markers. That schedules the debounced save for a verse whose text may be the translator's own saved scripture (exactly the case covered by the new test preserves saved verse content when only its title needs a suggestion).

saveVerse (~line 191) then unconditionally posts /ai-suggestions/usage with wasUsed: true whenever projectItem.isAiEnabled, so inserting an AI title records an accepted AI verse draft for text a human wrote. It also issues a redundant PUT of unchanged verse content.

One option: pass a flag through to saveVerse (or split out a markers-only update path) so the usage log fires only when the verse text itself came from a suggestion.

lastQueuedVerseRef advances before the queue-next POST, which the effect cleanup then aborts.

The ref is bumped here, before the request is issued, and the cleanup at ~line 275 aborts that POST. On any re-run of the effect, the guard at line 233 (queueVerseNumber <= lastQueuedVerseRef.current && !justEnabled) short-circuits, so the aborted request is never re-issued: nothing gets queued and setIsAiThresholdMet is never called for the chapter.

src/main.tsx wraps the app in React.StrictMode, so every dev mount walks exactly this path (mount → cleanup/abort → remount → early return).

Bumping the ref only after a successful response — or leaving the queue POST out of the abort signal — would avoid it.

A single failed poll ends generation permanently.

This branch sets error and returns without scheduling the next retry. Since polling is now the only delivery path for the whole group (up to 12 pending verse drafts plus the title), one transient 500 or network blip — e.g. during a token refresh — stops the loop and the translator has to reload the page.

Previously the chain restarted on each active-verse change; now the effect only re-runs when requiredIdsKey/activeNumbersKey change, which won't happen precisely when nothing is arriving. Scheduling the usual retry on error (with the error state still surfaced) would keep it self-healing.

const activeTargetVerse = verses.find(tv => tv.verseNumber === activeVerseId);
const isActiveVerseEmpty = !activeTargetVerse?.content.trim();

hasPendingTitle can make a fully drafted group show an AI error.

Reopening a completed chapter whose source has section titles but where the translator never entered target titles gives titledVerseNumbers = [] and touchedTitleVerseNumbers = [], so requiredTitlesKey is non-empty, the hook queues and polls for a heading, and hasPendingSuggestion stays true for every such group. The result is "Generating…" for 60s followed by the red "AI translation not yet ready. Please refresh the page" on pericopes that are already 100% translated.

The verse path is exempted from this via draftedVerseNumbers; the title path has no equivalent "this group is already drafted" guard.
