Change

Gaia's data server now refuses DATA_STRUCTURE=RAW with a 500: "The 'RAW' data structure has been deprecated - use 'DATAMODEL_GAIA' instead". Every star's Gaia XP address carried it, so no star whose XP file is missing from the source mirror could be restored or baked.

The parameter is swapped in 5,981 addresses: 829 manifests, their acquisition plans, color records, investigation ledgers and card sources, the src/sources records, and the generator's xpSampledUrl. 705 stars print the address in their baked datasets.json (WASP-103 also in its text), so those files and their inventories change by that string only.

Evidence and limits

Proves the change:

• The new form returns byte-identical files: β Pictoris's XP sampled and TRAPPIST-1's XP continuous spectra match the copies held (cmp).
• Acubens's real prepare step writes exactly the swapped datasets.json (cmp), 882 to 893 bytes; the other 704 were swapped and re-pinned the same way.
• K2-105's restore, which failed with the 500, now fetches both Gaia files and verifies 15 inputs.

Clean: 56 related telescope tests, check-no-hashes, check-color-spelling, check-prepared-delivery.

Prepared assets

• Published the 706 changed files (publish-runtime-assets.mts --since=origin/main, all verified live).
• Committed the refreshed inventories, no baked files.
