 ## Version boundary
 
+Local slice `1.0.1.106-beta.1` ports the Writing Desk's two-part block,
+88-tab inventory, authoritative catalog sync, copying transactions and 1.21.1
+GUI/model assets. Vial exchange reuses the existing shared helper; symbol copy
+cost defaults to one. Modern Container removal handles content drops while
+the block cleans up its partner. The renderer uses extracted item states.
+Current input helpers also correct Notebook right-click/scrollbar behavior.
+Page content is a derived view of the existing port components; no saved Page
+schema is replaced. Progression awards and optional JEI integration remain
+pending. Client appearance/input/catalog acceptance remains required.
+
+Local slice `1.0.1.105-beta.1` ports category Symbol Portfolios and Sealed
+Notebooks, reusing item textures/models and collection menu/import behavior.
+Portfolio volumes split at 252 pages. Sealed items use 1.21.1's 16-page draw
+and candidate exclusions, with Survival consumption, Creative retention and
+full-inventory drop fallback. No recipes are invented; discovery/library loot
+and JEI integration remain later work. Unported effects are still marked red.
+
+Local slice `1.0.1.104-beta.1` ports 1.21.1's all-or-nothing collection import
+to the current Binder menu: shift-click appends and cursor strip-click inserts
+before a page. Occupied page order is preserved, gaps are compacted and the
+empty collection is returned. Capacity/panel conflicts are checked before any
+mutation. This connects the newly ported collections to actual book assembly;
+the dedicated stored-collection input/UI remains later parity work.
+
+Local follow-up `1.0.1.103-beta.1` corrects old GLFW key literals retained in
+the Notebook screen. Escape always reaches the normal container close path,
+including focused search, and page-movement arrows use 26.3 key helpers.
+The player reported the search-focused GUI could not be escaped in .102;
+client keyboard acceptance must be repeated with .103.
+
+Local slice `1.0.1.102-beta.1` ports Notebook/Collation Folder storage, menu,
+Creative entries, Notebook crafting and the existing sparse page editor.
+The 1.21.1 capacities (252/27), Link Panel insertion rejection, held-item
+locking and search keyboard handling are preserved. The GUI uses 26.3 input
+events/extraction and the existing glyph-only item pipeline, while retaining
+the original page atlas proportions. Discovery, sealed notebooks, portfolios,
+Writing Desk and bulk Binder collection use remain unfinished.
+
+Local slice `1.0.1.101-beta.1` ports dropped-book entities, their open-book
+renderer/textures, decay/weather damage and persistent components. Handheld
+travel detaches only the active book and leaves it at departure after success;
+failed travel or a cancelled entity spawn restores it. Shared handling covers
+both book types and hands and keeps Return Link issuance after departure-book
+handling. The newer render-state-based pickup path replaces the old copy()
+workaround. Client rendering/pickup remain part of in-game validation.
+
+Local slice `1.0.1.100-beta.1` ports automatic Return Link policy from 1.21.1
+for handheld Descriptive Books, default DISABLED. ON_CREATION uses a persistent
+world-wide per-Age marker; ALWAYS issues on each successful arrival. Exact
+departure position/facing is captured before teleportation and issuance occurs
+after Disarm, with inventory-full fallback to a destination item drop. Ordinary
+Linking Books, failures and operator travel do not issue books. Stand/portal
+integration remains pending with those systems.
+
+Local slice `1.0.1.99-beta.1` ports the dedicated non-collectible arrival
+platform block from 1.21.1, reusing its opaque crystal model and strength 0.3.
+Fallback landings use it instead of collectible Crystal Blocks. No item,
+loot, pick-block result, or material Page is available. Existing platforms
+and the port's landing-search/footprint policy are unchanged.
+
 Local slice `1.0.1.98-beta.1` ports the 1.21.1 Accelerated environment page:
 stacking extra random block ticks in already-loaded player-nearby chunks,
 eight-chunk/16,384-attempt default budgets, fair rotating section allocation,
