bvandeusen dcfe55d731 feat(import-resilience L2): one-shot re-download for corrupt downloaded files
Layer 2 — remediate a corrupt file by re-fetching a fresh copy from its
source, bounded to a single attempt. Operator-requested 2026-05-28.

New backend/app/services/refetch_service.py:
- resolve_refetch_source: parse the failed file's sidecar → platform,
  derive the artist from the import path, find an ENABLED Source with a
  real feed URL for (artist, platform). Returns None for filesystem-only
  imports, missing sidecars, or `sidecar:<platform>:<slug>` synthetic
  anchors (not pollable).
- attempt_refetch: if not already refetched AND a Source resolves,
  delete the corrupt file (so gallery-dl's skip_existing re-fetches it),
  set ImportTask.refetched=True, and trigger ONE download_source
  re-check. Bounded by `refetched` so source-side corruption can't loop.

Wiring:
- Manual endpoint POST /api/import/tasks/<id>/refetch (only on 'failed'
  tasks). Returns refetch_queued / no_source / already_refetched /
  not_found / not_failed.
- Auto path in recover_interrupted_tasks: for each poison-pill row, if
  env FC_AUTO_REFETCH_CORRUPT=1, attempt_refetch (default OFF — the
  manual button is the primary path; auto is opt-in since re-fetch
  deletes a file + re-runs the downloader).
- Frontend: a cloud-refresh icon button on failed rows in ImportTaskList
  → stores.import.refetchTask → toast keyed on the result status.

Filesystem imports with no upstream return no_source — the operator's
only remediation there is replacing the file on disk, surfaced clearly
in the toast.

Tests: 404 unknown task, 400 non-failed task, no_source when
unresolvable, and the full resolvable-source path (file deleted,
refetched flag set, one download_source dispatched, second call is a
no-op). The resolvable test repoints the migration-seeded
import_settings(id=1) scan path rather than inserting a conflicting row.

FabledCurator

Self-hosted media curation — gallery, ML tagging, and subscription-driven downloading in one app. Part of the FabledSword family.

Combines what was ImageRepo (gallery, ML, importer) and GallerySubscriber (gallery-dl wrapper, subscriptions, credential capture) into a single product.

Status

Pre-v1. Not yet functional.

Quick start

For local development and testing, just:

docker compose up -d
# UI: http://localhost:8080

That uses sane dev defaults baked into docker-compose.yml and the dev override (docker-compose.override.yml, auto-merged) — local builds, DEBUG logging, exposed Postgres + Redis ports on the host. No .env required.

For a production-like deployment, override the dev defaults via shell env or a .env file (see .env.example for the variable names) and use:

docker compose -f docker-compose.yml up -d
# (skips the override so containers pull registry images)

Deployment posture

FabledCurator is designed to run inside a self-hosted homelab environment over plain HTTP. If you want TLS, terminate it at your reverse proxy. The app does not generate certificates, redirect to HTTPS, or set HSTS.

CI / Forgejo setup

The repo's workflows expect:

  • Runner label python-ci — a Forgejo runner with Python 3.14, ruff, and Node 22 pre-installed. Both ci.yml and build.yml use this label. The runner image (runner-base:python-ci) is built from CI-Runner/CI-python/ in the operator's workspace; make push from that directory builds and pushes a new image when toolchain pins change.

  • Repo secret RELEASE_TOKEN — a Forgejo PAT with the following scopes:

    • write:package + read:package — for docker push to git.fabledsword.com
    • write:release — for future release-cutting workflows
    • write:issue — for future issue-management automation

    Generate at https://git.fabledsword.com/user/settings/applications. The injected GITHUB_TOKEN cannot be used because it lacks write:package.
