What

• Deletes src/flows/converters.ts (convertToFlowDefinition / convertFromFlowDefinition) and its test, and removes the export * from './converters' re-export (it was part of the root and ./flows public export).
• Adds src/utils/id.ts with newId(prefix?) built on globalThis.crypto.randomUUID() (plus id.test.ts), and replaces every nanoid() call (10 files: FlowBuilder, sessionStream, data/mocks, AgentBuilder, json-path, errors, tracing, agentRun, MemoryManager, AgentExecutor, import swap only).
• Removes nanoid from package.json and package-lock.json (lockfile edited by hand to the single node_modules/nanoid entry plus the root dependency line; 19 deletions, no npm-version libc churn). Transitive nanoid 3.x copies used by ai/postcss are untouched.
• CHANGELOG Removed entries with migration notes; two doc comments in src/types/flow.ts no longer mention the converters.

Why

The converters targeted a flows-ai engine that was never a dependency and FlowExecutor never used them (donor-project residue, AUDIT section 4). nanoid is a runtime dependency used only to make opaque ids; Node 22 and Cloudflare Workers both provide crypto.randomUUID(), so no dependency or node:crypto import is needed (the Workers bundle stays Node-builtin free). No code in apps/agent-forge, examples or packages/create-loushy-agent imported the converters or nanoid.

Acceptance criteria

• src/flows/converters.ts and its test deleted; re-export removed; CHANGELOG Removed entry with migration note (no replacement)
• src/utils/id.ts exports newId(prefix?) on globalThis.crypto.randomUUID(); no node:crypto fallback needed
• Every nanoid import replaced; no test asserted the old id format (session test regex ^[A-Za-z0-9_-]+$ still matches)
• nanoid removed from package.json and package-lock.json; no workspace depends on it; npm ci --dry-run succeeds
• npm run build (incl. src/deploy/runtime.worker.ts bundle) and cloudflare adapter tests pass
• .fallowrc.json unchanged
• No changes to createAgent.ts, context/, react/, providers/*; AgentExecutor.ts import swap only

How verified

• npx tsc --noEmit: no errors
• npm run lint: 0 errors, 420 warnings (main: 433, so down 13)
• npm run test:types: no type errors
• npx vitest run (after build): 140 files passed, 2044 tests passed, 3 skipped
• npm run build && npm run build --workspace=packages/create-loushy-agent: success
• npx vitest run src/deploy: 5 files, 36 passed, 1 skipped
• npm run test:coverage: 140 files, 2044 passed
• npm run fallow: exit 0, 0 above threshold
• npm run docs:llms:check: passes (no README/docs changes)
