A ground-up hardening of live mode, driven by a production session in a nested-app monorepo that hit six distinct failure classes. Full design rationale in docs/LIVE-REWRITE-PLAN.md; every Codex-reported failure now has a mechanical fix and a regression test. Roots: live/roots.mjs resolves appRoot/repoRoot/contextRoot once at boot (keyed on dev-server configs, not monorepo brand markers), persists a manifest, and every live CLI re-anchors onto it at startup, so a helper run from the wrong directory can no longer fork session state. Context files are discovered upward to the git root. Render truth: variant_mounted / variant_mount_failed events give the journal per-variant mount state; failures reach the agent's poll queue, raise a persistent error card with Retry (no more localStorage wipe), and an attach probe names root/dev-server mismatches explicitly. The browser rehydrates from the server when localStorage is gone. Svelte: the scaffolder now parses with the app's own svelte 5 compiler. Control flow survives (an each collection crosses the contract as one structured prop), keyed each blocks hydrate synthetic keys, and anything a detached preview cannot support falls back to source-preview instead of shipping a wrong scaffold. Preview modules live in per-publish revision directories, defeating stale transform caches. Accept: CSS is reconciled, not appended. Matching selectors are replaced, params bake from params.json kinds, the compiler's unused-selector pass prunes superseded rules (pre-existing dead rules protected), a selector- loss postcondition refuses any write that would drop hand-written rules, and live-complete refuses to finish while live plumbing remains in source. Also: framework registry (live/frameworks/) with a crash-safe injection journal, session-store snapshot caching with read-only reads, protocol enum consolidation, steer Send button, honest DESIGN-panel empty states. Testing: new unit suites (roots, AST scaffolder, accept CSS, accept pipeline, framework conformance); e2e now fails on preview-tree 404s, proves computed-style mount for every variant, drives the Tune panel through baked params, and injects failures (broken mounts, republish, storage loss). New runtime fixtures: monorepo-nested-vite (repo root != app root) and vite8-sveltekit-stateful (each blocks + state). Nightly full-matrix cron. An independent adversarial review pass preceded this commit; its blocker and major findings are fixed and regression-tested. This work was produced with AI assistance (Claude Code).
