What

Many lazily built module bodies are now top-level constants with identical contents: Bash safety patterns and flag sets, plugin cache error strings, the MCP transport table, Remote Control refusal messages, cloud-hook explanations, workflow harness preamble text, PowerShell and environment sanitisation lists, and session name word lists. Load shape only, no visible change.

Evidence

bridge_carrier_no_ingress_origin

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
