What

PUT /workspaces/:id/files updates the file in the platform's stored config (DB / staging dir), but the container's mounted /configs volume is populated only at INITIAL provision. POST /workspaces/:id/restart re-launches the container but reuses the existing volume — file changes never reach the running container.

Repro

Create workspace via /org/import
Container starts with /configs/initial-prompt.md = original
PUT /workspaces//files/initial-prompt.md with new content → 200 saved
POST /workspaces//restart → container provisions new
docker exec <ws> cat /configs/initial-prompt.md → STILL THE ORIGINAL

Why it matters

Cant correct an in-flight workspace's prompt without volume teardown
Forces operators to re-import org template + lose memory state, OR docker exec to overwrite in place (bypasses platform audit)
Band-aid today: A2A directive at runtime telling agent to ignore the cached prompt

Fix shape

Either:

Restart handler should re-bind a fresh volume from current DB-stored config
Or PUT /files should write through to the running volume (use docker cp into mounted dir)

Severity

MED — not data-loss, but blocks the documented operator workflow for prompt updates

Tier

tier:medium

Working on fix. The root cause: ReplaceFiles offline path falls back to host-side template dir when writeViaEphemeral fails, but restart handler reads from the Docker volume. Fix: remove the fallback, return 503 so callers know to retry when Docker is available. PR: https://git.moleculesai.app/molecule-ai/molecule-core/pull/172
