| The token-scope and 48h grace-period fixes are the right cut for Railway-side destruction. What concerns me is the destruction that happens inside the managed environment. An agent running `DROP TABLE users` or `DELETE FROM orders` (no WHERE) against the live Postgres in that volume wipes data at the SQL layer; the grace period doesn't trigger because Railway never sees a delete API call. And the token is correctly scoped to that environment, so scoping doesn't catch it either. | ||

| The PocketOS incident also had the agent running SQL directly against prod. The chokepoint for that class has to sit at the agent layer where the SQL is composed, not at the platform API. Are you planning anything Railway-side for in-volume destruction, or is that explicitly out-of-scope for the platform fix? | ||

Add a language tag to the reply fenced block
The fenced block at Line 19 is missing a language identifier (MD040). Please mark it as plain text so markdown linting passes consistently.

Summary
Draft reply to
thisismahmoud_(Railway employee, OP, id=47949259) on Railway's blog post response to the PocketOS / Cursor production-database deletion incident. Story id=47948802 (1 point, 3 comments, 4 days old at draft time). OP describes two platform-side fixes: per-environment token scope, and 48h grace period on volume deletions. The reply argues that platform-API guardrails do not reach SQL-layer destruction inside the volume (DROP TABLE,DELETE FROM ... no WHERE), so an agent layer chokepoint is still required for that class. Closes with an open question to OP about whether in-volume destruction is in scope for Railway-side guardrails.ASCII-only punctuation throughout, single disclosure line at the top, single repo URL (in the disclosure), no install command, no policy comma-list, no built-in policy named, no custom-policy snippet, no three-scope / dashboard / version-number /

The angle in this draft (platform-vendor-API vs SQL-layer chokepoint) is materially different from each: it specifically engages with the Railway-side fixes the OP describes (token scope + 48h grace) and points to a class those fixes do not reach (in-volume SQL destruction).
