📝 Changelog

All notable changes to Formamorph. This fork's first line is 2.0.0 — a full TypeScript rebuild of the upstream JavaScript app (FieryLionite's Formamorph, ~v1.2) — with feature parity as the baseline plus new features on top.

🚧 2.0.0 is in development and not yet released. Entries accumulate here as work lands. When the version number is bumped, that marks 2.0.0 going live; until then this is a living list.

Each release groups changes as Major / Minor, then Added / Removed / Fixed, and within those by audience: 👤 user-facing · 🛠️ developer tooling · ⚙️ backend / invisible.

🚧 2.0.0 — In development

Everything below is relative to the point this fork diverged from upstream.

Major Changes

➕ Added

• 👤 User-facing
  • Custom 3D avatars — bring your own .vrm, or set a per-world custom player model.
  • In-app media player — a fully themed audio widget for TTS narration, with auto-generated TTS when the model is loaded and a one-click unload of the TTS model to free VRAM.
  • Redesigned world browser ("Discover") — card-grid layout, tag & author chip search/filtering, and world-preview image zoom.
  • AI output controls — automatic paragraph limits and length-based truncation, an optional "thinking / planning" step before the reply, and a smoothed character-by-character reveal of streamed text.
  • Markdown narration — the AI can format story text with bold/italic, bullet & numbered lists, tables (e.g. inventory), headings, blockquotes, and code; it renders live as the text streams in.
  • Token-based Context Window, auto-detected from your endpoint (LM Studio, OpenRouter, …) with a Detect button and manual override — conversation history now fills the model's real context instead of a fixed character cap, and an over-limit warning flags a value set above the detected maximum.
  • Portrait / mobile layout — a single-panel responsive mode alongside the three-panel desktop view.
  • Lore Dictionary — a keyword-triggered world-info editor; matching keywords inject lore into the AI prompt.
  • Full per-turn AI context viewer — see exactly what's sent to the AI on each turn, plus the raw response before sanitation — useful both for debugging and for authoring/tuning worlds.
• 🛠️ Developer tooling
  • Automated test suite built from scratch (Vitest + Testing Library) covering the new libraries, services, and components, plus a coverage script (npm run coverage).
  • GitHub Actions CI — typecheck, lint, and tests run on every push and pull request.
  • Optional VRAM monitor — a local helper (npm run vram-helper) and in-app readout that warns before loading TTS would exhaust GPU memory.
  • Project scaffolding: .env.example, .nvmrc, and a rewritten README.
  • This wiki, published automatically from docs/ by a GitHub Action.
• ⚙️ Backend / invisible
  • Full JavaScript → TypeScript conversion of the entire codebase (10 phases), finishing on strict mode with shared domain types under src/types.
  • World & save versioning — an APP_VERSION derived from package.json, idempotent import migration (migrateWorld) that upgrades legacy worlds at every import boundary, presence-based save-envelope detection, and version stamps on saves, exports, and the bundled worlds. (See the World Format versioning notes.)
  • Heavy save conversion and serialization moved to web workers so the UI never freezes on large files.
  • Reusable utilities extracted: world import/catalog, output length, AI-response parsing, tag/dictionary/highlight helpers, and a thumbnail cache.

➖ Removed

• 👤 User-facing
  • The fullscreen menu popup, replaced by the redesigned world browser.
  • The previous bundled example worlds (slime, sugarscape, veilwood), swapped for the current set.
• 🛠️ Developer tooling
  • In-repo planning notes and server stubs under src/docs/ (publish-feature plan, server README, tags-implementation notes, server-worlds stub).
• ⚙️ Backend / invisible
  • All legacy .jsx / .js sources, superseded by .tsx / .ts equivalents (views, contexts, workers, prompts, db & utils, UI primitives).
  • jsconfig.json (replaced by tsconfig.json) and a stray Idle.fbx animation file.

🐛 Fixed

• 👤 User-facing
  • Custom VRM models exported from v1.2 were silently stripped on import — now migrated and preserved.
  • Body-morph sliders now resize clothing meshes instead of clipping through them.
  • VRM outline color rendering issue.
  • AI response parsing errors that could break choices and stat updates.
  • The Settings panel no longer jumps vertically when its contents change.
  • Unsaved world edits are detected on exit, with a confirmation prompt to prevent data loss.
• ⚙️ Backend / invisible
  • Server-Sent Events streaming now handles chunk boundaries correctly — no dropped or garbled tokens mid-stream.
  • Removed side effects from the setPlayerStats state updater.
  • The recent-stat-change highlight timer is cleared properly, and streaming guards against a missing response.body.

Minor Changes

➕ Added

• 👤 User-facing
  • Markdown formatting toggle (Settings → Gameplay, default off) — when on, the narration prompt asks the AI to format with bold/italics, lists, and tables (e.g. inventory) using a floor-based rule (one bold + at least one italic per turn) that small models follow reliably; off keeps plain prose. (Reset Prompts to pick it up if you've customized the system prompt.)
  • Hide stat numbers from the narrator (Settings → Gameplay, default on) — the narration, planning, and choices requests receive stat descriptors (e.g. "severely injured") instead of raw values, so the model writes to how a stat feels rather than fixating on the number. Stat-updates still get the numbers; falls back to the number when a stat has no descriptor.
  • Slash commands in the action box (input starting with /) that bypass the AI; the first, /markdown test, types a rich sample through the real narration renderer to preview markdown formatting.
  • Use Custom Endpoint toggle in Settings → Endpoint — off uses the built-in default endpoint (fields read-only); on lets you enter and edit your own. Custom values are preserved when toggling off and back on.
  • Drag-to-reorder for worlds in the main menu.
  • Additional avatar color options.
  • Unified, consistently styled scroll areas across the app.
  • Tag truncation and a centered download control in the world browser.
  • LLM request status surfaced next to the status bar.
• ⚙️ Backend / invisible
  • Shared hooks and helpers: a createWorkerClient worker factory, a single IndexedDB open/promisify helper (idb), usePersistentState, useIsMobile, and a cached-thumbnail hook.

➖ Removed

• ⚙️ Backend / invisible
  • Dead code and noisy logging, including a leftover bufferToSentence helper and an auth-token console log.

🐛 Fixed

• 👤 User-facing
  • Mislabeled UI text and icons corrected.
  • The memory meter is now an accurate token gauge of the model's context window — prompt + (actually-sent) history + reserved output as a % of the window — fixing the old bar that mixed characters and tokens and counted the full untrimmed log.
• ⚙️ Backend / invisible
  • Entity IDs now use crypto.randomUUID() instead of timestamp-based IDs, avoiding collisions.
  • Lint cleanups across the converted codebase.
