-//! Self-describing per-plugin configuration: schema, redaction, merge, and the
-//! generic schema-driven HTML page the feeder serves at `/config`.
-//!
-//! The point of this module is that **the gateway carries no per-plugin config
-//! knowledge** and **the SDK carries no per-plugin field names**. A plugin
-//! declares its fields via [`FeederPlugin::config_schema`](crate::FeederPlugin::config_schema);
-//! everything here (redaction of secrets, merge-on-save, and the rendered form)
-//! is driven entirely by that schema. Add a feeder → it shows up with a working
-//! config form and zero UI/gateway changes.
-//!
-//! ## Persistence & precedence
-//!
-//! Config lives at `cache_dir/config.json` (the per-plugin dir handed to
-//! `configure()`). The plugin reads **file-or-env** at startup: env is the
-//! first-boot seed and stays authoritative until the operator saves through the
-//! UI, at which point `config.json` exists and wins. There is no runtime reload
-//! — a save returns `restart_required: true` (mirrors the gateway's
-//! `gateway-config.json` posture).
-//!
-//! ## Secrets
-//!
-//! Fields of kind [`FieldKind::Secret`] are **write-only**: never returned to
-//! the page (redacted to a `<key>_set: bool`), and a blank incoming value on
-//! save means "keep the stored secret".

-//! Feeder-driven enrichment — the "smart feeder / dumb gateway" pipeline.
-//!
-//! A feeder that self-publishes (has a `META_CORE_URL`) writes its own base
-//! record, then drives the **reused meta-sort enrichment plugins**
-//! (`metamesh-plugin-filename-parser`, `metamesh-plugin-tmdb`) over HTTP. Each
-//! plugin is handed the `metaCoreUrl` and writes its own fields straight back to
-//! meta-core (`PATCH /meta/{cid}` merge), so the gateway never touches
-//! enrichment — full separation of concerns.
-//!
-//! ## Ordering — why we poll
-//!
-//! tmdb searches on `originalTitle`/`movieYear`/`videoType` (which it reads from
-//! the record), and those are produced by filename-parser. So the pipeline is
-//! **filename-parser → tmdb**. The plugin `/process` contract is *async*
-//! (returns `accepted`, then writes to meta-core and POSTs a callback), so after
-//! kicking filename-parser we **poll meta-core** until `originalTitle` appears
-//! (bounded), read the merged fields back, and hand them to tmdb. Polling keeps
-//! the feeder stateless — no callback-correlation bookkeeping. The plugins'
-//! callback POSTs still fire; they hit the feeder's no-op `/enrich/callback`.
-//!
-//! The whole pipeline runs in a spawned background task so it never adds latency
-//! to the libp2p resolve path; the meta-share ingester propagates the enriched
-//! record on its next poll (~eventually consistent).

-//!   Fast but not IPFS-interop. The `_from_sample` entrypoint takes the
-//!   middle slice directly so plugins that can only fetch a partial range
-//!   (BitTorrent BEP 9, sliced HTTP) don't have to buffer the whole file
-//!   just to throw most of it away. **Rust-only by construction.**
-//! - [`compute_ipfs_cid`] is the standard IPFS CIDv1 produced over the full
-//!   bytes — raw codec `0x55` for a single-chunk file, UnixFS dag-pb codec
-//!   `0x70` rooted on chunked raw-codec leaves for larger files. Output matches
-//!   `ipfs add --cid-version=1 --raw-leaves=true --chunker=size-262144
-//!   --hash=sha2-256 <file>`.
-//!
-//! Cross-implementation parity for `compute_midhash256` with the TypeScript
-//! `FastHash.ts` is load-bearing — keep the fixture tests pinned, a regression
