Missing terrain, controller, weather, lighting, celestial, or the controller's minimum biome count is an **incomplete** warning, not an error: the compiler retains the seed-selected profile and traits for missing branches. The minimum is zero for Native, one for Single, two for Tiled/Grid, and three for Tiny–Huge. Native cannot consume authored biome pages; Single accepts only one. Unknown IDs, schema-v1 display-only symbols, wrong ordering, misplaced modifiers, duplicates, conflicts, missing/extra Link Panels, and oversized writing are errors. The Binder disables output and exposes the first error on the result-slot tooltip. When that error belongs to a page, its thumbnail is tinted and outlined red, the strip scrolls to it, and hovering it shows the diagnostic. This maps the parser's compact entry position back through any empty page positions. Rejected inputs remain removable. Binding an unwritten Descriptive Book rechecks its server-owned writing and reports the first error without creating an Age. A terrain symbol whose profile is unavailable is also rejected before Binder inputs are consumed.
The plan stores the original writing order, the authoritative semantic value of each resolved symbol, the Age seed, and a copy of the selected runtime profile. An explicit terrain page replaces the random terrain selection; an omitted terrain uses the seed-selected profile. Age loading uses the frozen runtime profile and does not need the original symbol definition or runtime-profile JSON. Existing bound books without plans are not reinterpreted. Page-free and Link-Panel-only books keep the pre-existing random path. Biome, lighting, weather, celestial, and feature effects are retained in the plan but will be applied in issues #33–#35; instability remains Milestone 6 work.

An explicit terrain page replaces the random terrain selection; an omitted terrain uses the seed-selected profile. The built-in Standard, Amplified, Cave, Island, Flat, and Void terrain pages now select their matching generation resources. Age loading uses the frozen runtime profile and does not need the original symbol definition or runtime-profile JSON, though its referenced noise, biome-preset, and dimension-type registry entries must remain available.

The Rivencraft Pages creative tab reads a generated index of bundled symbol definitions. Adding another valid JSON symbol under `src/main/resources/data/rivencraft/rivencraft/symbols/` includes its page automatically in the next build; no Java starter-page list needs updating. The server catalog still decides whether that page is valid for writing. External server data-pack symbols are not included in this bundled index.
