Stage 8 of simplification audit: generated build/meta layer + CI consolidation (~1,300 config lines + metadata bugs, audit §1.5–1.6)

[sroussey]

Context

From the 2026-08-05 simplification audit (workglow-dev/prd#77, docs/superpowers/notes/2026-08-05-libs-simplification-audit.md, §1.5–1.6 + Part 5 stage 8). Orthogonal to stages 4–7 — can proceed in parallel any time. Start with --check-only generators so drift becomes visible before anything is rewritten.

Already landed from this area (don't redo): license added to all 38 manifests, @workglow/javascript got a sideEffects allowlist, and util's ./worker types/import mismatch + missing worker-entry type builds were fixed (#686). Verified still outstanding as of 2026-08-06: 15 manifests still lack sideEffects — including packages/ai, which declares sideEffects: false while relying on module-side-effect registration (the exact bundler-drop hazard Part 3 item 11 flags) — and the workglow meta-package drift below.

• packages/workglow generation: 48 of 52 files are shims (27 provider shims = 9 distinct bodies), plus a 210-line exports map and a 25-entry tsconfig references mirroring dependencies. Generate from one manifest via the existing build.ts, with --check in CI. Fixes real drift found by measuring: 4 phantom browser conditions (anthropic/gemini/hf-inference/hf-transformers browser variants the packages don't ship), 3 browser-capable providers unexposed, 9 published packages unreachable through the meta-package (including indexeddb and supabase).
• Per-package scripts blocks: ~450 of 565 lines mechanically derivable from each package's exports map (14 of 38 packages byte-identical).
• tsconfigs: 25 of 38 byte-identical after normalization → shared tsconfig.base-package.json; generate references from deps. (The one real bug — packages/test missing 6 provider references — is in Test infrastructure: 21 CI-invisible test files, conformance-suite gaps, test tsconfig refs (audit §1.6 + Part 3 item 14) #701; coordinate.)
• Package metadata: one sync-package-meta.ts with --check — sideEffects for the 15 missing manifests (fixing the packages/ai false hazard specifically), plus the identical bugs/homepage/type fields.
• Entry-point convention: only util genuinely needs the 3-way browser/node/bun split; ai and workglow have all three entries identical (collapse to one); six packages are really 2-way; five providers carry 10 shim files whose entire diff is ./ai/index vs ./ai/index.browser — point the exports condition at the file directly (−16 files).
• Doc drift: libs CLAUDE.md lists dataset/debug packages that no longer exist, omits four that do, and documents root scripts (watch, test:bun, test:vitest) that don't exist; docs/technical/19-build-system.md quotes a turbo.json that doesn't match the real one. Generate the dependency-graph block from the workspace graph. (Also: CLAUDE.md's execution-model section still says ABORTED where ABORTING is the actual state — Fix concurrency and event emission across storage and task systems #686 fixed EXECUTION_MODEL.md but not CLAUDE.md.)
• CI YAML (§1.6): six bun jobs commented out while their 8 root scripts remain (16 of 40 root scripts are runner-token mirror pairs → one --runner flag); the same 5-step setup block repeats 15×; six live vitest jobs differ only in the run line → composite action + matrix (484 → ~150 lines).
