POST /projects now creates a project from optional USFM files. I validate the files on the server, check each book identifier and derive the selected books from the files. The existing blank-project flow is unchanged. Migration 0029 stores each original file verbatim in project_unit_usfm_imports, including tags the parser cannot preserve.

Imported verses wait until the source book has finished loading. Migration 0030 adds bible_books.text_ingested_at, backfills books that already have source text, and the worker sets it only after all chapters are stored. Books with unknown completion stay pending until ingestion confirms them. Queueing happens before the immediate import attempt so a concurrent worker cannot leave an import stranded. A failure in one book is logged without blocking the others.

Once the source is complete, matching verses are imported and genuine versification gaps are skipped with a warning. Retries preserve translator edits. Headings and paragraph markers remain in the original file; materializing those markers is follow-up work in #320. Missing book data and mismatched book identifiers now have separate error messages.

Validation: 646 tests passed, plus lint, formatting, typecheck, build and the docs check. CI passed on d62d542. I also applied both migrations and ran the seed against isolated PostgreSQL 16. Real HTTP requests covered successful creation and book-mismatch rejection. A smoke using the real worker and database confirmed partial-source waiting, completion, terminal versification gaps, unchanged raw USFM and retries without overwriting edits. Only the external source-provider responses were replaced with a deterministic local fixture. Lint retains three existing warnings in verse-audio.

Closes eten-tech-foundation/fluent-web#419.

Screenshots

These are API and test-evidence captures; the frontend import screen is covered by its separate web PR.

1) Create a project from USFM

The real local API returns 201 Created for a valid Genesis file. The database confirms that the raw file and its two translated verses were stored.

Create a project from USFM: real API returns 201 Created


2) Reject a mismatched book

A file submitted as Exodus with \id GEN receives 400 Bad Request and a message explaining the mismatch. No project is created for this request.

Reject a mismatched USFM book: real API returns 400 Bad Request


3) Wait for source completion

This local test report shows actual PostgreSQL snapshots before and after the real worker runs. The import stays pending with partial source text, then stores both matching verses after completion; a genuine missing reference does not leave it pending. The original file and a later translator edit survive retries.

Summary by CodeRabbit

  • New Features

    • Projects can now be created from uploaded USFM files, with imported content preserved and processed automatically.
    • USFM imports support section headings, semantic divisions, empty verses, and reliable chapter/book matching.
    • Imported content is materialized after source Bible text ingestion completes, with retry support.
    • USFM exports preserve supported headings and paragraph structure more accurately.
  • Bug Fixes

    • Improved validation and error reporting for missing, mismatched, invalid, or unsupported USFM content.
    • Prevented incomplete source books from being treated as fully ingested.

POST /projects takes an optional usfmFiles array, one file per book. When it
is present the server re-validates every file before writing anything (one
bad file rejects the batch), derives the project's books from the files, and
stores each file verbatim in project_unit_usfm_imports. That table is the
passthrough: every tag survives there whether or not Fluent renders it, which
a parsed form cannot promise — usfm-grammar drops the text after an unknown
\z tag, for one.

The editable rows in translated_verses are derived from the stored file. They
hang off the source bible's bible_texts, which a worker ingests after project
creation, so materialisation is two-phase: books already ingested get their
verses in the create request, and the ingestion worker finishes the rest
right after it creates the chapter assignments. Verses the source does not
have are skipped and counted, never invented.

📝 Walkthrough

Walkthrough

Changes

The pull request adds validated USFM project creation with verbatim file storage and deferred materialization. It tracks complete source-book ingestion, preserves section headings and semantic-division markers, updates USFM export and chapter content handling, and adds migrations, seeds, tests, and design documentation.

Project creation integration
src/domains/projects/projects.service.ts, src/domains/projects/projects.service.usfm-import.test.ts
Parses files before writes, derives project books from file codes, stores imports transactionally, queues incomplete source books, and retains the existing blank-project flow.
Source ingestion integration
src/workers/ingest-bible-text.worker.ts, src/workers/ingest-bible-text.worker.test.ts
Tracks chapter failures, records source-book completion after successful ingestion, and triggers pending USFM materialization from the ingestion worker.

Merge Risk: 🟡 Moderate · up to 94648

Some imported projects can remain pending or permanently omit verses when source ingestion is partial or another book repeatedly fails. These completion and reconciliation paths should be corrected before merge.

Explanation

The pull request includes export and roundtrip behavior that [#419] explicitly defers. src/lib/usfm-verse-serializer.ts adds heading-aware USFM serialization, and src/domains/usfm/usfm.service.ts uses that serializer. Related export tests and section-heading export documentation are also included. Verbatim import storage does not require this export implementation.

Follow-up review pass after the batch-abort fix (thanks for that — confirmed it now continues through all books and returns the first failure at the end). Found a few more items on the new bible_books.textIngestedAt gating and some pre-existing gaps this PR extends. Requesting changes on the backfill gap and the type-level Omit, which is worth a second look before merge.

Verified all five prior fixes — confirmed: empty verses now counted, materialization now concurrent, unsupported USJ nodes now warn. Two of those fixes introduced new regressions (backfill semantics, footnote leakage), and there are two pre-existing gaps in the enqueue/reconciliation path worth a look. Requesting changes on the backfill and footnote-leakage items since they risk silent data loss/corruption.

Comment thread src/workers/ingest-bible-text.worker.ts
Row existence in bible_texts proves some verses landed, not that the book is
complete, and there is no expected chapter or verse count to check it against.
A partially ingested book marked complete would let an import treat its missing
chapters as versification gaps and drop the translated content. Leave completion
to the code that has ingested a whole book; project creation re-queues any book
still null. Also corrects the migration identifier in the design doc.

Refs: #305
Footnotes and cross references parse to a note node, illustrations to figure
and study sidebars to sidebar. All three fell into the default branch, which
warned and then walked their content, concatenating that text onto the active
verse and storing it in translated_verses. Warn but do not descend into them.

Refs: #305
Three ways an import stayed pending with nothing left to finish it:

A failed queue.send was only logged, so creation returned success with no job
scheduled. Enqueue now runs inside the creating transaction and rolls the import
back; a blank project still tolerates the failure as before.

Completion reconciled only the project units of the job's own project. It is now
scoped to the Bible and book, joined through project_unit_bible_books so another
Bible's import is left alone, and finishes every project waiting on that book.

A sibling book's failure threw before reconciliation ran, so a book that keeps
failing stranded the completed one once the retries ran out. Reconcile the books
this job completed before the aggregate failure check.

Two-axis review: Standards (repo conventions, ARCHITECTURE.md/CONTRIBUTING.md) and Spec (fluent-web#419, plus fluent-api#288 via merged #320).

The shape is right — verbatim passthrough in project_unit_usfm_imports, all-or-nothing re-validation, and the pending→materialize lifecycle. Eight findings need attention before merge: five spec/correctness, three architecture. Details inline.

Markers are only validated here, at materialize time — parseUsfmFiles runs usjToVerseTexts but never verseMarkersSchema. A file with >4 headings before one verse, heading text >300 chars, or text on sd/cl passes creation (project + import row committed), then fails this safeParse deterministically on every retry: materialized_at IS NULL forever, surfaced only as a log line.

Please run the same validation in parseUsfmFiles so a file that can never materialize is rejected at creation, and consider a terminal state for the import rather than unbounded pending.

A well-formed file ending in \s1 (or any heading after the last verse) hits this USFM_INVALID and 400s the whole import. The spec bar is "never drop or transform a tag" / "don't reject files for tags Fluent doesn't render" — and the raw-file store exists precisely for tags the model can't materialize.

I get the constraint (no following verse row to anchor to), but this should either store the trailing heading somewhere (e.g. on the last verse or the import row) or be an explicit documented spec decision — today valid USFM is rejected.

fluent-web#418 lets book-code detection fall back to \toc3/\mt when \id is absent, but this requires a book node (i.e. \id) — a file that legitimately passed client-side validation is uncreatable here.

Either mirror the same fallback, or confirm the API deliberately narrows the contract (in which case #418's fallback produces files that can never create a project).

This walks the content of any non-heading, non-semantic-division para — so \tr table cells, \pb, list markers etc. concatenate into translated_verses.content. The raw file preserves the original, but the editable verse text is corrupted.

Suggest walking only the body-text marker allowlist (the same treatment NON_VERSE_TEXT_NODE_TYPES gives notes/figures/sidebars) and leaving the rest to the raw file.

convertUSFMToUSJ only logs parser.errors and returns ok (usfm-converter.ts:54–56 — outside this diff, so commenting at the call site). #418: "if any file fails to parse, reject the entire import." If non-empty parser.errors means malformed input, the fix is small:

if (parser.errors && parser.errors.length > 0) {
  logger.warn('USFM parser errors:', { errors: parser.errors });
  return err(ErrorCode.USFM_INVALID);

This service reaches into other domains' tables directly — the translated_verses insert here, plus books (L39–42) and bible_books/bible_texts (L86–100) reads — while ARCHITECTURE.md routes cross-domain access through the owning domain's public functions / repo layer.

const rowsByTable = new Map<unknown, unknown[]>();
const inserted: unknown[][] = [];
