 # DECK-0003 (SNO — Simple Nostr Objects) — feasibility and implementation plan

-## 6. Suggested sequencing
+## 6. Sequencing — what landed
+
+Built in this order, each step verified before the next:
+
+1. `quartz/…/cyberspace/deck0003Sno/` — payload, §1.9 validator, built-in
+   palette, palette-event reader, kind 33331, kind 11333 + the §8.10 work gate.
+   **50 tests**: the 25-case rejection table generated from `sno-reference.py`,
+   the avatar ladder computed from §8.10's pseudocode, all seven live objects as
+   fixtures.
+2. `commons/…/sno/SnoRasterizer` — CPU rasterizer, **15 tests**, one per rule §4
+   decides, plus the depth ordering a painter's algorithm gets wrong. Checked by
+   eye too: the object named Triforce comes out as a Triforce.
+3. `commonsUI/…/sno/` — Coil fetcher + `SnoThumbnail` for the cached static
+   view, `SnoObjectViewer` drawing straight to a bitmap for the drag (each drag
+   angle would otherwise be a half-megabyte cache entry), `SnoObjectCard` /
+   `SnoAvatarCard`, and a new `PlatformImage.toComposeImageBitmap()` beside the
+   existing Coil bridge.
+4. `amethyst/…/note/types/SnoObject.kt` + `SnoAvatar.kt`, dispatched from
+   `NoteCompose` and `ThreadFeedView`, stored addressably/replaceably in
+   `LocalCache`, fetcher registered in both image loaders.
+
+**Decisions as taken:** D1 accept (parity with sno-core — all seven objects
+read), D1b tolerate, D2 deferred, D3 read-only with the writer in quartz, D4
+inline quote + thread, D5 clamp at ±64 units.
+
+**Deliberately not wired:** kind 3330 bag items (D2), an authoring/modeling
+tool, and replacing a user's NIP-01 profile picture with their cyberspace
+avatar — that last one is a product decision about every feed row, not
+plumbing.
+
+### The original plan
 
 1. **Quartz parse + validate + built-in palette + the 25-case table.** No UI. Lands
    as a self-contained, fully tested module; `amy` can dump a parsed object for
