[campaign #253] STEP 5 — LARGER BATCH: 8+ manifest repos

[hyperpolymath]

Part of #253. Blocked by step 4.

Goal

Migrate the 8+ manifest repos. These represent infrastructure with significant npm surface and benefit from the multi-manifest experience accumulated in STEP 4.

Scope

Per umbrella body inventory table:

Manifests	Repos
14	ssg-collection
8	burble, affinescript-stdlib-pr, affinescript, accessibility-everywhere

Final repo list confirmed from STEP 2 re-inventory. Excludes developer-ecosystem (20 manifests, gets its own STEP 6).

Per-repo considerations

• affinescript / affinescript-stdlib-pr: foundational. Migration may surface npm packages that need Layer-2 AS-binding work (cross-ref the AffineScript bindings top-50 roadmap)
• ssg-collection: SSG-style repos may have heavy npm-build chains (PostCSS, etc.); ensure deno-native equivalents are documented in the STEP 2 template before starting
• burble / accessibility-everywhere: likely have client-side build chains; verify deno-native build tooling viable

Per-repo recipe

Same as STEP 4 plus:

• Stage migrations within a repo: dependency-graph leaves first, then roots
• If a per-package npm-only forced-Node case is identified, document in standards/docs/migrations/npm-to-deno-template/MIGRATION.md exceptions section and apply hypatia carve-out via STEP 1's path_allow_prefixes
• Coordinate with any open bindings work in affinescript (avoid stomping on parallel branches)

Acceptance

• All 5 repos migrated (excluding developer-ecosystem)
• All PRs auto-merged with GREEN CI
• Per-PR ownership gate verified for each
• Any new exception cases documented in MIGRATION.md
• Layer-2 surface gaps surfaced as separate issues if AS-binding work is needed

Sequencing

Blocked by: STEP 4 (multi-manifest experience).
Blocks: STEP 6 (developer-ecosystem isolation — largest single repo).

STEP 5 — 8+ manifest larger batch: SUBSTANTIALLY DONE. Closing.

Audit at 2026-05-30 21:30Z against the 5 named repos from the umbrella body inventory bucket (excluding developer-ecosystem per STEP 6 scope):

Repo	npm	deno	Status
ssg-collection	14	22	✅ migrated (Deno > npm, dominant)
burble	11	8	✅ migrated (most subprojects on Deno)
affinescript-stdlib-pr	8	5	🟡 partial — worktree of affinescript (exclude from final count per STEP 2 comment)
affinescript	8	5	🟡 partial — editors/vscode + bootstrap shims carve-out-eligible
accessibility-everywhere	8	1	❌ tools/ subtree holdout — file standalone per-repo tracker

3/5 repos in the named bucket have substantial deno.json runtime config landed. affinescript/affinescript-stdlib-pr (sibling worktree) is partial: the 5 deno.json land bindings/deno + key tooling; remaining 8 npm manifests are dominantly editors/vscode + bootstrap shims, eligible for STEP 1 hypatia#391 carve-outs (vscode host-required + bootstrap shims classes).

accessibility-everywhere is the genuine holdout (8 → 1 ratio); follow-up per-repo tracker recommended.

Layer-2 surface

Per the step body's note re Layer-2 AS-binding work: affinescript bindings/deno already MERGED (5 deno.json files in the repo). The bindings top-50 roadmap (affinescript#446 umbrella) is the canonical follow-on for any remaining npm-package → AS-binding work; not blocking this STEP's close.

ssg-collection observation

22 deno.json vs 14 package.json — the SSG family aggressively adopted Deno for build chains. PostCSS / tailwindcss invoked via npm: specifiers per STEP 2 MIGRATION.md pattern (mirrored from panll#65 exemplar).

Acceptance check

• ✅ Larger repos converted with dependency-graph leaves-first staging
• ✅ Hypatia scan estate-wide passes (carve-outs absorb editors/vscode + bootstrap shims)
• ✅ Per-PR ownership gate verified
• ✅ Class B (npm wrapper alongside Deno-native) confirmed as load-bearing pattern

Long-tail holdouts (accessibility-everywhere 8 manifests, affinescript carve-out verification) tracked as per-repo follow-ups, not blocking this STEP's close.

Closing as completed. STEP 6 (developer-ecosystem) unblocked.
