Summary

Mobile #333 replaces the Projects tab with a Milestones tab: a flat list of named translation units (project_units) across the user's projects, with row subtitles like Baka NT · 3 milestones. Today units have no display name and there is no user-scoped flat list endpoint — this PR adds that API.

  • Migration 0029: named project_units (name, type, connectivity_profile) and projects.source_bible_id
  • Nested milestones CRUD under /projects/{projectId}/milestones
  • Flat GET /users/{userId}/milestones for mobile Home tab (requireSelf)
  • Project list/detail include milestoneCount; DELETE /projects/{id} → 409 while units remain
  • Remove projectUnitStatus from PATCH /projects/{id}; milestone status lives on milestone PATCH
  • DBL ingest accepts optional projectUnitId so new milestones do not fan out to sibling units
  • GET /projects/{projectId}/chapter-assignments?milestoneId= filters to one unit

Pairs with eten-tech-foundation/fluent-mobile#333 (product ticket).

Refs #342.

Test plan

  • Unit tests: milestones service/routes, user-milestones requireSelf, project delete 409, ?milestoneId filter
  • npm test
  • Manual Postman + psql: POST /projects → default milestone → second milestone → nested + flat list return name / projectName / milestoneCountDELETE /projects 409 → delete milestones → delete project 204

Summary by CodeRabbit

  • New Features

    • Added milestone management with create, view, update, and delete support.
    • Added milestone types, statuses, names, connectivity profiles, and project milestone counts.
    • Added a user endpoint to view milestones across accessible projects.
    • Added optional milestone filtering for project chapter assignments.
    • New milestones can link Bible books and initialize related chapter assignments.
  • Bug Fixes

    • Projects without milestones now load correctly.
    • Project deletion reports a conflict when milestones remain, unless cascading is requested.
    • Ingestion assignments can now target the relevant milestone.

Introduce named project units as milestones with nested CRUD, a flat
user-scoped list endpoint, schema migration 0029, and companion updates
so multi-unit projects remain loadable and deletable safely.

Milestone platform

Layer / File(s) Summary
Data model and project lifecycle
src/db/*, src/domains/projects/*, src/domains/usfm/*, src/test/utils/*
The migration and schemas add source Bible, milestone name, type, and connectivity fields. Project queries expose milestone counts. Project creation, updates, deletion, rollback, fixtures, and project-name resolution follow the new project-unit model.
Milestone domain and project APIs
src/domains/milestones/*, src/app.ts
New types, repository operations, services, authenticated project routes, and tests support listing, creating, retrieving, updating, and deleting milestones. Creation links books, creates chapter assignments, and queues eligible text ingestion.
User milestone aggregation
src/domains/users/milestones/*
A self-access route lists milestones across projects available to the authenticated user in the active organization.
Unit-targeted assignments and ingestion
src/domains/chapter-assignments/*, src/domains/projects/chapter-assignments/*, src/lib/queue.ts, src/workers/*
Chapter-assignment queries and ingestion jobs accept an optional project-unit ID and limit processing to that unit when provided.

Handle projects without book rows before enforcing source_bible_id.

The backfill populates projects.source_bible_id only through the project_units to project_unit_bible_books join. A project without such a row remains NULL, so the DO block raises and the migration never reaches the NOT NULL constraint. The milestone design permits projects with zero milestones, so this state can be valid. Assign a source Bible or remove those empty projects before migration. If they must remain without one, defer the NOT NULL constraint until another source can populate the column.

@kaseywright, following up on this CodeRabbit finding on fluent-api#343 (migration 0029 / source_bible_id backfill).

Fluent-web already requires at least one book on project create, and POST /projects requires bookId[], so we expect the backfill to succeed for normal data. The migration checks that every project has a source_bible_id before applying NOT NULL (review.md §2.9 / fluent-api#342).

I do not have access to the shared dev DB, and 0029 will only run after merge — so I have not been able to verify this against real data myself.

Question: does anyone need to confirm in the database that there are no legacy projects without book rows before we merge, or are we ok to proceed as-is?

Reject or apply bibleId and bookId updates.

The PATCH route accepts both fields through updateProjectWithUnitsSchema. This service removes them before persistence. A request that changes another field can therefore succeed while silently ignoring the bibleId or bookId update. If these fields are immutable, remove them from the update schema. Otherwise, implement their update contract.

@kaseywright, could you take a look at this CodeRabbit finding on fluent-api#343?

What it's about: PATCH /projects/{id} accepts bibleId and bookId in the OpenAPI schema, but updateProject has always stripped those fields and never persisted them. That behavior already existed on main; this PR did not introduce it.

Why it came up now: we now set projects.source_bible_id on create, and milestones inherit that Bible. So bibleId on PATCH looks like it should update the project's source Bible, but it still has no effect — the API returns 200 while silently ignoring those fields.

What we checked: fluent-web and fluent-mobile do not appear to call PATCH /projects/{id} with bibleId or bookId today.

Options we see:

  1. Treat source Bible / books as immutable after create — remove them from the PATCH contract and reject them explicitly (small contract fix).
  2. Track as follow-up — pre-existing issue, outside the fluent-api#342 / feat(milestones): add milestones API for mobile #333 #343 milestones API scope (product driver: Update Projects Tab to Milestones with Flat Milestone List and Offline Controls fluent-mobile#333).
  3. Implement real bible/book updates on PATCH — likely large scope and probably not aligned with the milestones model.

Question for you: after create, should the project's source Bible be fixed, with book scope managed on milestones? Your read on which option fits would help us decide how to respond to this review comment.

Prevent duplicate bookId entries from inflating milestone metadata, and
lock the project row during delete so concurrent milestone creation cannot
bypass the 409 guard via cascade delete.

@kaseywright, if any item doesn’t make sense, feel free to discard it.

Items for future verification (out of scope for this PR)

This PR was reviewed with AI-assisted code review. A few items came up in that process that do not block the #333 deliverable; we’re noting them here for future verification. They are not part of this merge.

  1. Duplicate bookId on POST/PATCH /projects (projects.types.ts) — pre-existing on main; POST /projects can accept [3,3,4] and persist duplicate rows. Outside refactor: Bring API CI into parity with fluent-web #333 AC.

  2. deleteProject({ cascadeUnits: true }) bypasses lock/409 guard — only used today for grant rollback after POST /projects. Low risk for now.

  3. Ingest worker fan-out when projectUnitId is missing (ingest-bible-text.worker.ts) — fallback to all project units; sensitive with multi-milestone. Current enqueue passes projectUnitId; risk mainly on stale queue jobs.

  4. Milestone aggregation SQL scans whole tables (milestones.repository.ts, projects.query-builder.ts) — perf on sync endpoints; not a functional refactor: Bring API CI into parity with fluent-web #333 gap.

  5. Cleanup nits — duplicated ingest enqueue, duplicated aggregation/zero-fill SQL, redundant validBookIds fetch in code touched here. Low priority.

thank you for posting this @JonathanSeehagen . I'll touch base with the BCS team on Monday and check their progress on this feature. I do know that they are writing a migration script for the PROD data so that we do not have data loss.

Then, I will follow up here with any feedback on this PR.
