 # Pixel Island Summoner
 
-Local prototype. Open `index.html` with Live Server, or run:
+Browser-only prototype for a shared pixel-art island.
+
+## Run
+
+Open `index.html` in a modern browser. No build step or third-party dependency is required.
+
+## Current prototype scope
+
+- Draw pixel assets in the in-browser editor.
+- Save assets to the local library.
+- Place static assets and summon dynamic assets onto the island.
+- Dynamic assets default to right-facing on spawn; left-facing is rendered by mirroring during movement only.
+- Local voting, hiding, remix/copy edit, and import/export tools are included.
+
+## Phase 1 changes
+
+- Asset data is normalized to schema 2+ compatible shape.
+- Dynamic left-facing pixels are not stored; `faces.left` is represented as `mirror`.
+- Empty depth/light metadata is omitted or normalized.
+- Editor tools include Draw, Erase, Fill, Pick, Undo, and Redo.
+
+## Phase 2 changes
+
+- Local save uses a compact Phase 2 envelope in `localStorage`.
+- Pixel planes are bbox-cropped and RLE-compressed when this is smaller than raw cropped data.
+- Compact asset bundles can be exported separately from world snapshots.
+- World snapshots contain placements, dynamic summons, and an asset manifest rather than full asset blobs.
+- Local object/asset mutations append small sync events to `eventLog`.
+- IndexedDB asset/snapshot cache helpers are included for future server-backed missing-asset fetches.
+
+## Phase 3 changes
+
+- Terrain rendering is chunk-cached instead of using one large terrain canvas.
+- Only terrain chunks intersecting the current viewport are drawn.
+- Static and dynamic objects outside the viewport margin are culled before sprite generation/sorting.
+- Dynamic runtime updates are stepped at 15 Hz and capped per frame to avoid spiral-of-death on slow devices.
+- Rendering pauses while the browser tab is hidden and resumes on visibility change.
+- Tile/object lookups use a small spatial index for inspect, erase, and nearby-target searches.
+- Data tab reports visible terrain chunks for quick performance inspection.
+
+## Phase 4 changes
+
+- Editor schema is now 5.
+- Added Line and Rect tools. Rect supports filled rectangles with Shift; right-click erases line/rect cells.
+- Added Select tool. Drag to select a rectangular area, then drag the selection or use arrow keys/buttons to move it.
+- Nudge buttons move the active selection; without a selection they shift the whole drawing.
+- Added horizontal/vertical flip, palette-colored outline generation, and clear selection.
+- Added editor PNG export/import. PNG import quantizes the image to the current island palette and current canvas size.
+- Added keyboard shortcuts: B/E/F/I/L/R/S for tools, Ctrl/Cmd+Z/Y for history, arrows for moving selected pixels, Escape to clear selection.
+
+## Export formats
+
+- **Export full JSON**: human-readable full local state.
+- **Export compact**: compact local state suitable for saving/transferring.
+- **Export snapshot**: placement state plus asset manifest; requires asset bundles or cache to render fully.
+- **Export asset bundle**: compact asset blob list for missing-asset transfer.
+
+
+## Phase 4 follow-up adjustments
+
+- PNG import now chooses the editor canvas size from the image size. Square 8/16/32/64 PNGs import at their native size; other sizes are fit into the nearest supported square canvas.
+- Depth is now three-state: high, normal, and low. High brightens sprite pixels; low darkens them.
+- Right-clicking the world canvas clears the current map selection instead of moving or placing the selected asset.
+- Dynamic sprites now pause intermittently instead of walking continuously.
+- Night rendering is darker.
+- Object picking now uses sprite-sized, per-opaque-pixel hit testing, so transparent pixels are not clickable.
+- The CSS font stack now tries `3x5 MT Pixel Font` first. The font file itself is not bundled.
+
+## Phase 5 changes
+
+- Editor schema is now 7.
+- Fixed the Advanced Draw depth controls so `Depth / High / Low / Clear` wrap inside the drawer instead of overflowing to the right.
+- Added Phase 5 guardrails in the Data tab:
+  - local asset/object volume counters,
+  - duplicate-content count,
+  - orphan placement checks,
+  - terrain compatibility checks,
+  - hidden/report counters.
+- Added `Validate world` export for pre-server integrity checks.
+- Added local object reporting from the selection bubble. Reported objects are hidden locally and stored in a local moderation report log.
+- Added `Export moderation report` for review/debug data.
+- Added `Clear reports` to clear local report logs without un-hiding already hidden objects.
+- Added soft local guardrail limits: 160 assets and 220 world objects. Existing objects can still be moved; new saves/placements are blocked when the local cap is reached.
+
+## Phase 5 follow-up changes
+
+- Static sprites now anchor closer to the center of their tile instead of the front corner.
+- Object selection is pixel-accurate: transparent sprite cells no longer select the object, and tile inspection does not select hidden/transparent areas.
+- Right-clicking the map clears selection silently.
+- Hidden panel now lists both hidden library assets and hidden map objects. Objects hidden by Report appear there and can be restored with Show again.
+- Report now opens a reason dialog with Cancel and Report + Hide actions.
+- Library cards include Place/Move, which makes dynamic human assets easier to reposition.
+- Default bundled pixel art was replaced with a new set: Hill Cottage, Pine Cluster, Shell Rock, Wave Skiff, Fisher Kid, Moss Cat, Koi Fish, and Cloud Gull.
+- Added a static Ship role/subtype. Ships can be placed on water, float subtly, and periodically emit ring ripples.
+- Local storage key was bumped to load the new default set in this prototype build.
+
+## Phase 5 polish
+
+- Night lights now draw after the darkness overlay and use fixed bright cores/halos, so lamp pixels visually ignore the night darkening pass.
+- The sky color now transitions quickly around dawn and dusk. Day and night remain mostly stable instead of drifting continuously.
+
+
+## Phase 5 Effects
+- Nearby objects receive a faint surface glow from adjacent light sources.
+- Light cores are less dazzling, while night ambient darkness is lifted slightly.
+- Land-moving dynamic sprites emit small terrain-colored step particles.
+
+
+## Visual FX follow-up
+- Step particles now vary in hue / saturation / lightness around the terrain color.
+- Nature assets shed tiny drifting leaf/petal dots.
+- Coast foam uses two slow-rotating porous bluish-white layers.
+- Depth now affects phase-aware sprite shading for sun/moon exposure.
+- Added toggles for lights, particles, and the day-night cycle.
+
+
+## Phase 5 UI / particle follow-up
+- Coastal foam no longer uses cut-out holes.
+- Walking particles are less frequent and use more visibly varied colors.
+- Remix always creates a new derivative asset; Edit updates the user's own original asset.
+- Advanced Draw now includes configurable particle emitter cells for any asset.
+- PNG export/import moved to the Data tab.
+- Nudge arrow buttons under the canvas were removed; keyboard arrow nudging remains.
+- UI text is larger overall, while palette color-code labels keep their small size.
+
+## Rotation policy build
+
+This build adds count-based island rotation.
+
+- Default island display cap: 250 objects.
+- The local display cap is adjustable from Data > Visual settings.
+- Objects are not deleted when the cap is exceeded; the effective oldest objects are omitted from the island display.
+- Upvotes delay rotation-out by slot adjustment. Downvotes advance rotation-out.
+- Local publish / republish quota: 5 objects per author per rolling hour.
+- Replacing or republishing a rotation-hidden object updates its `publishedAt` and consumes one quota slot.
+
+Server-side periodic rotation code is in `server/rotation_worker.py`.
+
+Example:
 
 ```bash
-python3 -m http.server 5500
+python server/rotation_worker.py world.json --write
 ```
 
-Then open `http://localhost:5500`.
+It performs:
 
-## Current controls
+1. Permanent-hide marking for extremely downvoted objects.
+2. Randomly samples 50 hidden historical objects.
+3. Republishes the top 20 by upvote count.
+4. Reapplies the active display cap.
+5. Adds permanent-hidden objects to `adminReviewQueue` for deletion checks.
 
-- Open Pixel Studio with the large `+` button.
-- Left drag on the pixel canvas: draw.
-- Right drag or middle drag on the pixel canvas: pan.
-- Mouse wheel on the pixel canvas: zoom.
-- Use `Light` to paint light cells with the selected palette color.
-- Use `Set Outline` to apply the selected palette color as a thin sprite outline.
-- Click map objects to select them and show their bubble.
 
-## Notes
+## Local-only rotation note
+This build does not call a server from the browser. The island display cap is applied client-side, and objects over the cap are kept in local save but not drawn. Server recirculation / permanent hiding only happens when `server/rotation_worker.py` is run against exported world JSON.
 
-- Data is saved in `localStorage`.
+## Exhibition Policy Revision
-- The vote bubble is local only.
+
-- Server-side moderation is not implemented yet; see the TODO comment in `app.js` near `voteSelected()`.
+This build separates **Asset** and **PlacementObject** more explicitly.
+
+- Asset: a durable library work. Remix only copies pixels and lineage into the canvas.
+- PlacementObject: a temporary island exhibition object. It can rotate out while the Asset remains in Library.
+- Edit has been removed. To revise a work, remix/copy it, save a new Asset, then delete the old one if desired.
+- Publishing requires a prototype local account. The first 24 hours allow 5 public placements/hour; day 2+ allows 10/hour.
+- The island exhibition has 250 visible slots: 150 newest slots and 100 random revival slots.
+- Upvote rank effect is capped at +50 votes.
+- Capacity rotation and extreme downvote rotation use the same user-facing explanation: the island exhibition is full, but the work remains in Library.
+- Server moderation can mark `permanent_hidden` / `violation_hidden`; these are hidden from authors and viewers. Admins can restore them with the Python worker.
+- Particles are disabled offscreen/when zoomed out and capped at 200 active particles.
+
+### Server worker
+
+```bash
+python server/rotation_worker.py world.json --write
+python server/rotation_worker.py world.json --restore object123 --write
+python server/rotation_worker.py world.json --hide-violation object123 --write
+```
+
+The Python worker is the authoritative production policy. The browser mirrors it only for local prototype use.
+
+### Compression lab
+
+```bash
+python server/compression_lab.py exported_world.json
+```
+
+Use this to compare minified JSON, gzip, zlib, and Brotli when available. Production should use the compact asset codec plus HTTP gzip/Brotli rather than hand-rolled custom compression first.
