// P2 consistency: "omniglyph" is a registered CompressionMode/engine but several
// parallel mode/engine lists (DB validation, stacked-pipeline allowlist,
// deriveDefaultPlan single-mode map, combo schema, MCP tool enums) had not been
// updated to include it — causing e.g. defaultMode:"omniglyph" to validate on
// write but get silently dropped on DB read-back. This file proves the round trip
// and the parallel-schema acceptance.
