If a stable bootstrap is missing those values or disagrees with currentRelease / the selected immutable branch manifest, treat the stable response as stale and follow the exact immutable manifest/bootstrap from this root. The current Instruction Author text/plain bundle embeds core, all ten required modules and the exact current MicroStation key-in reference, so a restricted client that validates the bundle may use those key-in semantics without a second discovered-URL fetch. The standalone text/plain key-in transport remains the primary direct representation when the bundle was not loaded; Markdown remains the authoring/source representation. Restricted clients may also use the applicable explicit text/plain transports for on-demand iNGs_Geo, on-demand STN013411, general MicroStation cells, or the standard color-table reference. Restricted clients may also use the explicit on-demand Project Environment text/plain transport when a task materially concerns Configurations, WorkSpaces, WorkSets, project-environment resources/diagnostics or migration.",

Every emitted name -> co= conversion must then be freshly looked up in the applicable authoritative mapping, including follow-up turns; preserve the pending requested color through the confirmation exchange and cross-check name -> index -> RGB before emission.",

If the applicable table cannot be consulted, the semantic color is unclear, or a shade name is ambiguous, do not guess a numeric co= index.",
