Extract embedded `affinescript-*` subtrees to their own repos (or to developer-ecosystem/)

[hyperpolymath]

Context

PR #391 (extract road-skate/ to its own repo) is the first of a series. Five more subdirectories in this repo are similarly-misplaced consolidations from the 2026-04-22 "Consolidate ecosystem projects into affinescript repo" commit, and need the same treatment.

These are not part of the AffineScript compiler — they are downstream brand-surface / integration / runtime-binding projects that share the AffineScript dependency but are independently scoped.

Subtrees needing extraction

Subtree	Suggested new home	Notes
affinescript-vite/	developer-ecosystem/affinescript-ecosystem/affinescript-vite/	Vite plugin. Already has a parallel directory under the developer-ecosystem monorepo — the embedded copy here is a stale duplicate. Diff the two before merging.
affinescript-dom/	developer-ecosystem/affinescript-ecosystem/affinescript-dom/ (or its own repo)	DOM bindings for browser-host targets.
affinescript-pixijs/	developer-ecosystem/affinescript-ecosystem/affinescript-pixijs/ (or its own repo)	Pixi.js bindings.
affinescript-tea/	developer-ecosystem/affinescript-ecosystem/affinescript-tea/ (or its own repo)	The Elm Architecture (TEA) framework.
affinescriptiser/	hyperpolymath/affinescriptiser (already exists; embedded copy is duplicate)	Drop the embedded copy; standalone repo at hyperpolymath/affinescriptiser is the source of truth.

Stays in this tree

• affinescript-deno-test/ — approved Deno-test-harness exemption per CLAUDE.md.

Extraction pattern (lifted from PR #391)

For each subtree:

1. git subtree split --prefix=affinescript-vite -b vite-extract (or per-subtree branch name)
2. Strip RSR template scaffolding from the extracted branch (verification/proofs/, stale "AffineScript-Vite" READMEs copy-pasted between siblings, etc.)
3. If pushing to a new repo: gh repo create hyperpolymath/<name> --public --description "..." --homepage "..." then push the extracted branch as main.
4. If integrating into developer-ecosystem/affinescript-ecosystem/: diff against the existing copy there first; cherry-pick / replace as appropriate.
5. Single removal PR against this repo: git rm -r <subtree>/ + fix any references in docs/workflows. Auto-merge ON, GPG-sign.

Why one issue per series instead of per-subtree

The same agent should sweep these in one focused session — they share the same template-residue cleanup, the same reference-update mechanics, and the same risk class (each is one PR per extraction). Per-subtree issues would fragment without benefit.

Cross-reference (triage 2026-05-27): scope-disambiguated against #229 and #230 — these three are distinct, not consolidatable.

• ESTATE: total ReScript-surface elimination from all .affine (committed goal; blocked-on #228) #229 — dialect-syntax cleanup: eliminate ReScript surface from .affine files in independent consumer repos (burble, idaptik-dlc-vm, git-scripts, …). Blocked-on LANG: type/effect grammar has no module-qualified path — Pkg.Type/Pkg.Effect unrepresentable (estate-wide port blocker; ADR-014) #228. No vendoring/extraction involved.
• ESTATE: de-vendor embedded affinescript trees (bofj-kitt / proof-burrower / developer-ecosystem) #230 — de-vendoring: pull stale vendored copies of the affinescript tree OUT of three consumer repos (bofj-kitt, proof-burrower, developer-ecosystem).
• Extract embedded affinescript-* subtrees to their own repos (or to developer-ecosystem/) #392 (this issue) — extraction: push five misplaced subtrees (affinescript-vite/, affinescript-dom/, affinescript-pixijs/, affinescript-tea/, affinescriptiser/) OUT of the affinescript repo itself into their proper homes (developer-ecosystem monorepo or standalone repos). Reverts the 2026-04-22 consolidation commit 11485aa.

#230 pulls copies INTO upstream alignment (consumer repos shed vendored upstream snapshot); #392 pushes subtrees OUT of upstream (this repo sheds misplaced ecosystem projects). Inverse directions, disjoint target sets, distinct problem classes. Consolidation is not safe.
