# Rivencraft 26.3 beta 1.0.1.136-beta.1

Collects the player-validated .130–.136 port slices since 1.0.1.129-beta.1.
For Minecraft 26.3, NeoForge 26.3.0.99 and Java 25. The Minecraft 1.21.1
release and its Dynamic Dimensions backend are unchanged. This remains an
incomplete beta port; use matching client/server builds and separate saves.

## Link Modifier and Age creation

- Edit a Descriptive Book Age's full signed 64-bit seed. Existing chunks remain;
  newly generated terrain uses the new seed. Occupied Ages and stale/remote menu
  requests are refused. Seed input supports Enter or focus loss without game keys
  taking over while typing.
- Operators can retire an unoccupied Age through a separate confirmation action.
  Its exact dimension directory is archived under `world-retired-ages`; the Age
  is tombstoned and cannot reload after restart. Other Age data remains intact.
- Failed Age creation now rolls back the new level, index, initial name, library
  writing, instability and season policy before publishing the catalog. Cleanup
  removes only the newly created directory; pre-existing storage is protected.
  Persistent filesystem failures or process crashes are not transactional guarantees.

## Optional integrations

All integrations remain optional and are never bundled.

- **JEI:** searchable symbol pages, Link Panel variants and portfolios, with Ink
  Mixer/Writing Desk/Book Binder guidance. Internal Blank Pages and empty portfolios
  remain hidden. Tested with JEI 31.17.0.109 and MezzConfig 0.7.1.
- **TerraBlender:** recognizes registered Overworld and Nether region biomes from
  installed biome mods, including Biomes O' Plenty. Nether-region biomes join the
  Cave-compatible authoring pool and use Nether material rules. Tested with
  TerraBlender 26.3.0.0.9 and Biomes O' Plenty 26.3.0.0.16. The requested Native Cave
  pool changes and Native Nether/End pages remain separate work in #111.
- **Serene Seasons:** No Seasons, Seasons and all four Eternal modes operate per
  Age. Missing policies are seed-selected only when Serene is installed; Cave Ages
  disable seasons. Dynamic whitelist updates synchronize without restarting, while
  eternal policies leave the Overworld calendar unchanged. Tested with Serene
  Seasons 26.1.2.0.7 and GlitchCore 26.3.0.0.5.
- **Ruins:** exact-template pages appear in creative and JEI. Authored Ages permit
  only their selected templates; Ruins' surface, biome and distance checks remain.
  Duplicate pages increase selection weight and attempts (32-attempt cap, without
  lowering higher Ruins settings). The first three copies are free; each later
  copy adds 100 instability, even beyond the attempt cap. Tested with Ruins
  26.3.2NF. Duplicate template basenames disable the bridge to prevent ambiguity.

## Validation and remaining work

Both Minecraft builds pass. Every included slice passed player in-game checks;
the latest client log confirms JEI, TerraBlender/BOP, Serene/GlitchCore and Ruins
loaded together. Disposable dedicated-server checks covered seed changes with
unchanged old chunks, retirement/archive isolation, injected creation failures,
optional-mod absence, region discovery, season policies, Ruins template placement
and restart/unload/reload persistence. Test fixtures/worlds were removed and test
servers stopped. No permanent game tests were added.

Books and crystal portals still use animated fallback previews. Live destination
renderers, remaining discovery/configuration parity and random-Age glyph descriptions
remain unfinished. The current expanded-catalog dedicated two-client regression
and full parity/release gates remain open. Shared 1.21.1/26.3 follow-up issues are
not complete merely because one version's implementation works.
