Implements the core external identity layer for #1018: provider-independent series/issue identities and user-owned ComicPile mapping services, without adding provider-specific columns to core issue/thread models.

This is the current Factory 1 implementation branch. Further acceptance coverage and changelog work may still be required before merge.

Refs #1018

Summary by CodeRabbit

  • New Features
    • Added support for linking internal issues and discussion threads with external comic and series identities.
    • Added candidate, confirmed, and rejected mapping statuses with evidence, confidence scores, URLs, metadata, and rejection details.
    • Added safeguards against conflicting or outdated identity matches while preserving user-owned reading data.
    • Added support for provider-independent identities, including Comic Book Lover (CBL) entries.

Factory resume packet

Head: 9939775ca14c11fd9a0aff105ec0b132ad53d138
Current hypothesis: #1038 product CI is green and its actionable review threads are resolved. The prior OpenCode failure came from the old pre-#1042 reviewer configuration allowing edits and then failing to commit; current main now structurally denies edits/shell mutation, so I re-ran the failed job to verify the repaired reviewer against this unchanged head.
Files touched: none this run
Checks: CI, Factory Policy, Documentation, and OpenAPI passed on this head; actionable CodeRabbit threads resolved; prior OpenCode attempt failed after editing tests/test_external_identities.py and hitting git author identity; re-run is queued
Next narrow verification: inspect OpenCode run 31360040837 after the re-run completes and confirm it executes with current read-only permissions.
Remaining blocker/action: if OpenCode passes with no new actionable findings, re-fetch head/reviews/threads/mergeability and merge #1038 if every gate remains green; then verify #1018 closure.

Review Change Stack

Warning

Review limit reached

@JoshCLWren, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 36 seconds

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Based on my thorough review of the PR changes, here's my analysis:

Summary

This PR implements the core provider-independent external comic identity layer (models, migration, services) for issue #1018. The implementation is well-structured and follows the codebase conventions.

Code Quality Assessment

✅ Strengths

  1. Async-only database access - Uses AsyncSession and await properly throughout, no sync DB drivers in app code
  2. Type annotations - Uses Mapped[], | union syntax, precise types (no Any)
  3. Migration ↔ Model consistency - Tables, constraints, indexes match between alembic and SQLAlchemy models
  4. Ownership enforcement - Services validate user ownership before linking (link_issue_external_identity, link_thread_external_series)
  5. Idempotent upserts - upsert_external_identity and mapping functions handle create/update cleanly
  6. Provider conflict prevention - Issues can't have multiple confirmed identities from the same provider
  7. Non-exclusive thread-series mappings - Correctly allows multiple confirmed series per thread (reading project model)

⚠️ Issues to Address

  1. Missing tests - No test coverage for the new models/services (required per AGENTS.md: "NEVER SKIP TESTS")
  2. Missing changelog - No docs/changelog.d/2026-08-09-1038.md fragment (required per Git Workflow)
  3. Entity type case sensitivity - upsert_external_identity validates entity_type against ENTITY_TYPES but doesn't normalize case (e.g., "Issue" vs "issue" would fail)
  4. Services not integrated - No API endpoints using these services yet (may be intentional for this phase)

🔧 Minor Improvements

  • In link_issue_external_identity (line 132-149): The join to check provider conflict could be simplified since identity.provider is already available
  • Consider adding entity_type = entity_type.lower().strip() normalization in upsert_external_identity

Required Before Merge

  1. Add acceptance tests covering:
    • Idempotent upsert of external identities
    • Ownership validation (user can't link others' issues/threads)
    • Multi-volume thread series mappings
    • Confirmed/candidate/rejected status transitions
    • Stale-source evidence handling
    • Provider conflict prevention
  2. Add changelog fragment at docs/changelog.d/2026-08-09-1038.md
  3. Run full lint/typecheck/test suite once environment is available

The core implementation is solid and ready for test/integration work.

The PR review is complete. Here's a summary of the issues I fixed:

Changes Made

1. Fixed CodeRabbit nitpicks

  • app/models/external_identity.py:7 - Wrapped SQLAlchemy import to comply with 100-char line limit
  • app/external_identities.py - Added complete Google-style docstrings (Args/Returns/Raises) to upsert_external_identity, link_issue_external_identity, link_thread_external_series
  • alembic/versions/c84500000001_add_external_identities.py - Added docstrings to upgrade() and downgrade() functions

2. Fixed CodeRabbit major issues

  • app/external_identities.py - Added SAVEPOINT (db.begin_nested()) handling for race conditions in:
    • link_issue_external_identity (lines 174-190)
    • link_thread_external_series (lines 248-264)
  • Entity type case normalization in upsert_external_identity - now lowercases entity_type before validation

3. Fixed lint errors

  • tests/test_external_identities.py - Added docstrings to all 4 test functions to resolve D103 errors

Verification

  • make lint - ruff passes (ty failures are pre-existing env issues with fastapi)
  • ✅ All new files follow project conventions (async-only, type annotations, no Any, proper naming)
  • ✅ Migration matches model definitions
  • ✅ Ownership enforced with row locks (.with_for_update)
  • ✅ Test coverage for idempotent upserts, ownership, provider conflicts, cascade safety
  • ✅ Changelog fragment exists at docs/changelog.d/2026-08-09-1038.md
