1.3.0 (2026-07-10)

Features

• Detect non-faststart whole-file mp4 (moov after mdat) at ingest and log a one-line callout; add opt-in PODSPINE_REMUX_NON_FASTSTART to remux such books to faststart on demand — a cache-managed stream-copy (no re-encode) served from the saver cache and regenerated/evicted like a cached chapter, never a pinned duplicate — so podcast clients seek quickly. MP3/OGG/FLAC, already-faststart mp4, and chaptered books are unaffected. (#61)
• Add per-book .podspine.toml overrides: a sidecar beside a single-file book (Author - Title.podspine.toml) or inside a folder book overrides settings for just that book — storage_mode, force_embedded_chapters, remux_non_faststart, default_cover_url, plus troubleshooting knobs disabled, title, author, and force_reingest — with precedence sidecar → CLI/env → global config → default. Server-wide keys placed in a per-book file are ignored with a warning. (#62)
• Serve whole-file episodes — folder-of-MP3 tracks and chapterless single files — in place, streaming them directly from the read-only library instead of copying them under the data dir; this removes the silent duplication those books used to cost (an existing library reclaims the copies on its next re-scan). Chaptered books are unchanged (full/saver). (#59)
• Add an opt-in saver storage mode (PODSPINE_STORAGE_MODE=saver) that keeps chapters in a bounded on-demand cache (PODSPINE_CACHE_SIZE/PODSPINE_CACHE_TTL) instead of keeping every chapter split on disk — cutting the data-dir footprint for chaptered books (whole-file books such as folder-of-MP3 tracks stream in place regardless of storage mode) for a small first-play delay per chapter. Ingest still splits each chapter once to record its real byte length, so saver saves disk, not ingest time. (#53)
