Adding the first milestone proposal docs. If more proposal docs are created we can add them to this branch. Otherwise, merge when the work begins.

Summary by CodeRabbit

  • Documentation
    • Added a proposal for transitioning projects to a two-level project and milestone hierarchy.
    • Documented planned data migration, API, frontend, and access-control impacts.
    • Added a technical review identifying implementation risks, missing safeguards, open decisions, and recommended delivery phases.
    • Expanded review guidance for project deletion safeguards, role deduplication, access updates, progress reporting, connectivity settings, and book ownership.

📝 Walkthrough

Walkthrough

The PR adds a Project-to-Milestone hierarchy proposal and a corresponding implementation review. It covers schema changes, data consolidation, API and frontend updates, blocking defects, open decisions, and a phased rollout plan.

Changes

Project-Milestone hierarchy

Layer / File(s) Summary
Target hierarchy and schema
docs/proposals/milestones/workflow_project-hierarchy.md
The proposal documents current projectUnitId coupling and defines Project, Milestone, and project_units schema changes.
Migration and application workflow
docs/proposals/milestones/workflow_project-hierarchy.md
The proposal specifies project consolidation, milestone routes, project API changes, frontend updates, risks, and blocking decisions.
Review findings and rollout order
docs/proposals/milestones/workflow_project-hierarchy_review.md
The review adds migration deduplication requirements, deletion safeguards, connectivity and progress contracts, book-attribution guidance, a two-phase access workflow, and phases 0–6 with execution gates.

Estimated code review effort: 2 (Simple) | ~15 minutes

Merge Risk: 🟠 High · up to 72d13

The proposal is not ready to merge because its current migration and API design could cause destructive deletion, altered connectivity behavior, incorrect progress reporting, or unreviewed access changes when implemented.

only removes collisions with existing master grants; update it to deduplicate
non-master grants by the complete uniqueness key (user_id, org_id, role_id)
before assigning project_id to :master_id, or remove the option entirely. Add a

project_units.connectivity_profile before re-parenting. Ensure merged milestones
retain their original connectivity profile.
- Line 182: Define the overall progress contract for GET /projects before
implementation, specifying the denominator, milestone weighting, overlap

double-counted or skewed by milestone size.
- Line 170: Update the fenced code block containing the directory tree in the
workflow project hierarchy document to specify a language identifier, such as
text, and preserve the tree content unchanged.
- Line 100: Update the migration behavior for projects with no
project_unit_bible_books rows so it fails or quarantines them with a clear
repair path instead of skipping and logging only a warning. Ensure the migration
cannot continue while any project lacks the required non-null source_bible_id,
preserving the 100% rollout gate.
- Line 250: Fix the MD028 markdownlint warnings around the affected blockquotes
by removing blank separator lines within the blockquotes or prefixing those
separators with the blockquote marker, while preserving the existing quoted
content.
- Line 186: Update the DELETE /projects/:id behavior documentation to define
safe semantics for projects containing multiple milestones: either reject
deletion when the project is non-empty, or explicitly require and document full
cascading deletion with confirmation and tests. Replace the “Keep as-is”
statement in the project hierarchy proposal and cover re-parented milestones and
their child data.

## 3. Smaller Notes

- **`POST /projects` role grant.** The route grants the creator a PM role and, on failure, compensates by deleting the project it just made (`projects.route.ts:239-246`). Since §4 already opens this handler up to simplify it, fold the grant into the same transaction rather than leaving the compensating delete in place.
- **`GET /projects/:id/books` loses milestone attribution.** It `selectDistinct`s on book id (`books/project-books.repository.ts`), so duplicates across milestones collapse cleanly — the plan is right that it "just works." But the book-details metadata dialog needs to know _which_ milestone owns a book to hit `/project-units/:id/book-details`. Either add `projectUnitId` to the response or source that list from the milestone endpoint.

Preserve all milestone associations in the project-books response.

Because Section 2.1 allows overlapping book scopes, adding one projectUnitId to a distinct book row is insufficient. Return one row per milestone/book or include every owning projectUnitId; do not select an arbitrary owner.

Preserve connectivityProfile during consolidation.

projects.metadata.connectivityProfile is not in the grouping key, and the migration steps do not copy it to project_units.connectivity_profile. If projects with different profiles merge, non-master milestones inherit the master project's profile. Add the profile to the grouping key, or backfill a milestone override before re-parenting.

Make missing source-Bible rows a migration failure, not a warning.

The migration skips projects without project_unit_bible_books rows, but the rollout gate requires 100% non-null source_bible_id. A skipped project can remain without the project-level Bible required by the new API and UI. Quarantine these projects or fail with a repair path before continuing.

Define the overall progress contract.

The proposal does not define weighting or overlap handling for milestones. A chapter sum can double-count overlapping books, while an unweighted milestone average favors small milestones. Specify the denominator and status aggregation before implementing the API and frontend.

Define safe semantics for DELETE /projects/:id.

After consolidation, one project can contain multiple milestones. The existing cascade can therefore delete every re-parented milestone and its child data when a user deletes one project. Reject deletion of non-empty projects, or make the full cascade explicit with confirmation and tests.

Corrections to the review doc, each verified against the code first:

- Fix the user_roles dedup SQL. The previous form only removed grants
  colliding with an existing master grant; two non-master projects
  granting the same user the same role survived it and then collided
  inside the single UPDATE. Replaced with a ranked-CTE dedup across the
  whole merge group, master preferred.
- Gate the access-widening sign-off on step 8 (where widening happens)
  rather than step 9, and resolve the resulting conflict with the
  single-transaction requirement by splitting the migration into a
  dry-run phase and an execute phase.
- Note that overlapping milestone scopes give a book several owning
  project units, so a single projectUnitId on a distinct book row would
  target an arbitrary milestone.
- Correct the gap count in the verdict.

New findings added to the review:

- DELETE /projects/:id (blocking). projects -> project_units ->
  chapter_assignments / translated_verses are all ON DELETE CASCADE, so
  post-consolidation a single delete destroys every milestone under a
  merged project.
- Consolidation silently rewrites connectivityProfile: it lives in
  projects.metadata, is absent from the grouping key, and no step
  backfills it onto the new milestone override column.
- "Overall progress" has no defined contract, and overlapping book
  scopes make a chapter sum double-count.
- The skip-and-warn edge case for projects with no bible book rows
  contradicts the 100% non-null source_bible_id rollout gate.

Rollout table updated accordingly: phase 5 splits into dry run and
execute, and the DELETE guard joins phase 2.

Lint fixes to the proposal doc: tag the directory-tree fence (MD040) and
separate the consecutive IMPORTANT callouts with empty HTML comments
(MD028). Comments are used rather than "> " separators so the three
alerts keep rendering separately.

- §2.8: the recommendation contradicted the bullet above it. "Counted
  once per milestone" is the double-counting the first bullet rejects.
  Replaced with an explicit choice of unit applied to both numerator and
  denominator: chapter-assignment instances (recommended, matches how
  chapter_assignments is keyed and needs no tie-break rule) or unique
  (book, chapter) across the project.

- §4.3: the Phase B freshness check only covered merge-group membership,
  which is not what the reviewed report is derived from. Group
  membership can be unchanged while the grants underneath it changed, so
  a role granted between phases would be re-pointed at the master
  without appearing in the approved report. Checksum the full user_roles
  move input, or lock those rows and re-derive the report inside the
  transaction.
