Castwright 1.0.0

Castwright 1.0.0

Initial release. The full v1 pipeline takes a manuscript from upload to a
chaptered audiobook on disk: parse, attribute each line to a character, audition
voices, generate per-chapter audio via a local TTS sidecar, listen / revise, and
export to M4B or MP3 zip with cover artwork and chapter atoms.

✨ Headline features

📖 Manuscript → audiobook pipeline (new)

• Ingest — upload accepts .md / .txt / .epub / .pdf; chapter names are
  extracted at parse time; parse-only import lets the user confirm metadata
  (author / series / standalone) before the book lands on disk (plans 02, 12).
• Analysis pipeline — cast detection runs through one of three analyser modes:
  Gemini cloud (default for hosted, free-tier rate-limited), local Ollama (default
  for self-host, auto-falls back to Gemini when the daemon is unreachable), or
  manual file-drop coworking. Sticky analysis survives leaving the analysing view
  (plans 06, 29, 32).
• Generation stream — per-chapter SSE (progress / chapter_complete /
  chapter_failed / idle); sticky generation survives every navigation except an
  explicit Stop or queue drain, with Pause / Resume via POST /pause (plans 16, 32).

🎙️ Local TTS sidecar + voice library (new)

• Sidecar — a local Python FastAPI sidecar hosting two engines: Coqui XTTS v2
  (zero-shot cloning) and Kokoro v1 (English-only, eager-loaded, ~1 GB VRAM). The
  analyser and Coqui auto-evict each other to free VRAM with an inline banner
  (plans 14, 14a, 30).
• Voice library — per-engine catalogs, family grouping (af_* / am_* /
  bf_* / bm_*), drag-to-assign onto cast members, per-character overrides scoped
  per-engine so a Coqui ↔ Kokoro switch preserves assignments, sample playback
  against a user-editable line, and compare-two-cast-members (plan 22a).

🎧 Revisions, export & persistence (new)

• Revisions and drift — A/B audio audition before accept / reject; rollback
  preserves the prior MP3 as <slug>.previous.mp3 so it's non-destructive; a
  pending-revisions pill + full diff view (plan 20).
• Audiobook export — M4B (embedded cover, per-chapter chap atoms, optional
  desc / ldes metadata), MP3 zip (chaptered MP3s for Smart AudioBook Player /
  Audiobookshelf), and sync-folder save (drops the M4B into a sync directory). A
  LAN download tile generates a QR for sideloading; jobs can be cancelled /
  retried (plans 32, 33, 39).
• Workspace persistence — per-book on-disk state (cast.json,
  manuscript-edits.json, revisions.json, change-log.json, audio renders),
  round-tripped through atomic JSON writes with renameWithRetry for Windows /
  OneDrive races (plan 27).

🏗️ Under the hood

• Five-tier test harness — Vitest frontend + server, pytest sidecar, Pester
  for PowerShell helpers, Playwright e2e in mock mode; one-shot via npm run verify (plan 37).
• Three-tier commit gate (husky v9) — commit-msg Conventional-Commits
  validator, pre-commit verify:fast, pre-push full verify (plan 38).
• OpenAPI as the single source of truth at openapi.yaml; src/lib/api-types.ts
  generated via npm run openapi:types (plan 24).
• Mock mode round-trips against an in-memory map for jsdom tests + design
  fixtures (VITE_USE_MOCKS=true).
