# Rivencraft 26.3 beta 1.0.1.120-beta.1

Collects the player-validated .116–.120 port slices since 1.0.1.115-beta.1.
For Minecraft 26.3, NeoForge 26.3.0.99 and Java 25. The independent 1.21.1
release is unchanged; full gameplay and optional-integration parity remain incomplete.

## Libraries and writing

- Ported Legacy library generation, shared schematic, chest loot and five correctly
  oriented book/page stands. Libraries generate after decoration in eligible new
  non-Cave Age chunks, using the 1.21.1 spacing, terrain and clearance checks.
- Library loot defaults to `LEGACY`; optional `AGE_ONLY` limits new library Pages
  to known symbols originally written into that Age. Original writing is saved
  separately and restored on reload. Older Ages without it have an empty Age-only
  pool. Ordinary Books replace stand Pages when that pool is empty.
- Added operator library placement, candidate/probe/loot diagnostics, session-only
  test spacing and a locator limited to nearby already-loaded chunks.
- Hand-prepared Link Panel ink cost is server-configurable (default two). The
  Ink Mixer still consumes one ink unit and one paper per panel. Writing Desk
  ink handling now uses the shared service.

## Crystal portals

- Ported craftable Book Receptacles with all six mounting orientations and the
  existing 1.21.1 model/book transforms. A bound Linking or Descriptive Book
  activates a valid connected crystal frame, including supported irregular frames.
- Reused the bounded crystal flood/tension algorithm, placement protection events,
  rollback, owner persistence, restart repair, frame cleanup and traversal cooldown.
- Empty-hand removal closes the portal and returns the book. Breaking the holder
  or its crystal support closes it and drops a recoverable open-book entity.
- Player and non-player travel reuse book destinations, safe arrival, Intra-Linking,
  Disarm and momentum rules. Descriptive Books share the same landing resolver
  with portals; no separate portal exit offset is added. Player Return Link policy
  and progression remain in force.
- The animated fallback surface renders its facing sides and uses destination sky
  tint. The Open Portal advancement and receptacle recipe unlock are restored.
  Live destination views are still pending optional integration work.

## Instability and colored decay

- New Ages save operator-only creation-time score contributions and deterministic
  provider selections using all five Legacy decks. Existing Ages remain neutral;
  reloads/config changes do not reroll stored plans.
- Initial scoring covers Bright Lighting, Accelerated, Corrupted Pages, ineffective
  Cave sky/weather modifiers, excess and biome-forced structures, and extra suns.
  Corrupted Pages now bind successfully and retain their animated redacted text.
- Ported 18 potion providers: local/global Blindness, Fatigue, Hunger, Nausea,
  Poison, Slowness, Weakness and Wither, plus hostile Regeneration/Resistance.
  General effects affect eligible Survival/Adventure players and living entities;
  Creative/Spectator remain exempt. Local variants require sky exposure.
- Added a bounded occupied-Age scheduler, owned-effect cleanup, provider controls
  and operator score/status, enable/disable, session test-score and pulse commands.
  Effects supplied or extended by another source are preserved.
- Ported Blue, Purple, Red and White decay with the existing 16x16 textures,
  hardness/air conversion odds, saved per-color frontiers and attempt sequence.
  White retains stepping-contact magic damage. Decay has no item form or drops.
- Spread uses only already-loaded candidate chunks, bounded attempts and action
  budgets. Fluids, block entities, critical/unbreakable blocks, infrastructure,
  protected tags and claim events prevent conversion.
- The first resolved book/portal arrival is saved for spawn protection. Re-enter
  an older Age once to record it. Global/Age/provider and world-mutation controls
  gate spread; existing decay blocks remain when spreading is disabled.
- Test a color with `/rivencraft_port instability decay blue 32` (also `purple`,
  `red`, `white`); output includes actual changes and nearby tracked coordinates.
  Scores are not added to ordinary book or Binder displays.

## Validation and remaining work

Player in-game checks passed .116–.120. Both the 26.3 and 1.21.1 builds passed;
Gradle has no standalone test sources. Targeted disposable dedicated-server checks
covered library placement, portal entity travel and restart ownership/cleanup,
potion application/cleanup and persistence, all four decay colors, saved spread
continuation, and bedrock/fluid protection. Test servers were stopped and their
worlds removed.

Full writing recovery/penalties, live material-abundance profiling, other instability
hazards, remaining discovery/stations and optional integrations still need port work.
Unported hazard cards remain saved and are reported as unavailable, rather than
being replaced with different cards. Book previews remain the animated fallback.
Machine acceleration (#112), Writing Desk model placement (#113), and the matching
1.21.1 universal dropped-book fix (#114) remain tracked separately.

Use matching client/server beta builds (catalog protocol 10). Keep Minecraft tracks
and saves separate, back up beta worlds, and do not downgrade saves containing new
blocks or data to earlier betas.
