Import Media

About this section: Import MediaQueue cloud-sync handover bundles; the worker imports them in the background.

Purpose

Consume the upstream cloud-sync handover bundles from /mnt/ubuntu-nas/node2/assets/sync/ into the global library (asset, asset_gallery, asset_collection) per Decision 639. The CGI never imports inline; it queues batches into import_job for the background worker (Decision 640).

Flow

Scan: walks the mount for .ready sentinels and records new ingest_batch rows.
Pre-flight: validates the manifest shape, sentinel pair, and per-item decisions; no library writes.
Queue: auto-preflights if needed, then inserts an import_job row. Live progress shows on Import Tasks.
Bulk queue: select multiple batches and queue them in one click; the worker drains the queue in priority + FIFO order.

Example

Scan finds 37e428d2-a4f6-4a31-bacf-0c835fb24084.ready. Tick its checkbox (or several at once), click Queue selected. The worker claims the next queued job within seconds and writes job_* events as it progresses.

Consequences

The library is site-agnostic. Sites surface library content via asset_site_membership, gallery/collection membership, content allowlists, and access packages.
VIDEO-SIMPLE syncs import as stable asset_type=video rows with asset_subtype=video_simple, duration, HLS, transcript, cloud-package, and library-cover deliverables.
Cancel is allowed only while a job is queued; once running, only systemctl stop gpu-admin-panel-import-worker stops it.
Action remove only soft-deletes rows via deleted_at; nothing is hard-deleted.
Frosted, blurred, and vivid_blurred derivatives are intentionally not persisted.

Deeper dive

Sourced from gpu-floor/MIGRATION-INTRO.md and the queued-worker decision in DECISION_LOG.md.

Worker contract

A long-running import-worker.pl daemon claims queued jobs using SELECT ... FOR UPDATE SKIP LOCKED (MariaDB 10.6+). It updates heartbeat_at every few items; if a worker dies, its running jobs are reset to queued after the configured stale threshold (default 15 minutes).

Sentinel protocol

A bundle is consumable only when both <sync_id>.json and <sync_id>.ready exist and the JSON has status = completed and verification.passed = true. The importer recomputes manifest_sha256 at consumption time so audit history records what we actually ingested.

Source-of-truth mapping

source/source.json -> asset_source (cold provenance).
source/data/photo.manifest.json + photo.analysis.json + photo.meaning.json + photo.family.json -> asset_ai_run rows with explicit analysis_kind; unknown filenames are captured with source_data:<file>.
Bundled cover_hash -> asset_cover linked to the parent asset.
Containers of type gallery -> asset_gallery + asset_gallery_item junctions.

Idempotency + integrity

Every multi-row write is wrapped in AdminDB::transaction. Hash-based UNIQUE keys make re-running the same batch a no-op. Per-item failures isolate to ingest_batch_item.decision = failed with last_error; the batch becomes partial when any siblings still succeeded.

Read-only mount + ledger boundary

The /mnt/ubuntu-nas/node2/assets tree is read-only for admin consumers. The importer never writes to upstream or deletes .ready sentinels; all consumer state lives in ingest_batch / ingest_batch_item / ingest_event / import_job in admin_panel.
