 **`kiln-core/src/script.rs`** — Rhai scripting **host** (the script-facing types live in `kiln-core/src/api/`, below). The script-author's reference is [`docs/script-api.md`](../docs/script-api.md).
 - `Registerable` trait — `fn register(engine, log_sink)`: a type's hook for installing itself (Rhai type name + getters/methods) on the `Engine`. Implemented by every `api` type plus `Glyph`/`Keyring`.
 - `ScriptHost` — owns the Rhai `Engine`, the compiled scripts (`HashMap<String, CompiledScript>`), one persistent `Scope` per scripted object (`HashMap<ObjectId, Scope>`), and the shared `LogSink`. (There is no shared board queue: each hook call drains into a local `Vec<BoardAction>` that it returns to `GameState`.) Built with `ScriptHost::new(&Rc<RefCell<Board>>, &HashMap<String, String>)`: the first arg is a shared ref to the active board (cloned into the write-API closures and each scope's `Registry`), the second is the world-level script pool. Each script is compiled once per `script_key` (the object's `script_name` — a world-pool name, or a synthetic `BUILTIN_*` name assigned by `expand_builtin_archetypes` so identical built-ins share one AST); the source is the pool entry for that key, or the object's embedded `builtin_script`. `CompiledScript` records which hooks the AST defines (`has_init`/`has_tick`/`has_bump`/`has_grab`/`has_enter`). **Per-object output queues no longer live here** — each `ObjectDef` owns its `queue: ObjQueue`. Reports compile/unknown-script failures onto the `LogSink`; runs nothing.
-- Lifecycle hooks, each taking `me` (an `ObjectInfo`) and `state` (a `ScriptState`) before any hook-specific arg: `init(me, state)`, `tick(me, state, dt)`, `bump(me, dir)` (`dir` is the `Direction` the bump came *from*, fired when any solid — the player, another object, or a pushed crate — presses into this object), `enter(me, dir)` (the non-solid counterpart to `bump`: fired on a non-solid object when a solid *relocates onto* its cell — a player/object step, a pushed crate, a `teleport`, or a `shift` — with `dir` the side the entrant came from, best-effort for teleport/shift), and `grab(me, state)` (fired when the player walks onto a `grab` thing — the only grab trigger). All optional — detected via `AST::iter_functions()` by name **and arity** (bump and enter are arity 2). Run one object at a time (the per-object loop lives in `GameState`): `run_tick_on(id, dt)` / `run_init_on(id)` / `run_bump(id, dir)` / `run_enter(id, dir)` / `run_grab(id)` / `run_send(id, fn, arg)`, all funneling through `run_hook_on_one` and **returning the `Vec<BoardAction>` they drained** for `GameState` to apply. `run_hook_on_one` builds a fresh `ObjectInfo`, pushes `[me, state, (arg)]`, and calls the hook tagged with the object's id. The `Tick` hook is **gated on an empty queue** (`hook != Hook::Tick || info.queue.is_empty()`), so an object with pending actions/`Delay` from an earlier tick isn't re-ticked; all other hooks fire whenever defined. After the call — **whether or not the hook was called** — it always drains the object's queue, so a delay still advances on an object that has no `tick` (or whose `tick` was skipped this frame). Runtime errors go to the shared `LogSink` (drained to the log), not fatal.
+- Lifecycle hooks, each taking `me` (an `ObjectInfo`) and `state` (a `ScriptState`) before any hook-specific arg: `init(me, state)`, `tick(me, state, dt)`, `bump(me, dir, by_player)` (`dir` is the `Direction` the bump came *from*, fired when any solid — the player, another object, or a pushed crate — presses into this object; `by_player` is `true` when the immediate bumper is the player — a pushed crate reports `false`), `enter(me, dir)` (the non-solid counterpart to `bump`: fired on a non-solid object when a solid *relocates onto* its cell — a player/object step, a pushed crate, a `teleport`, or a `shift` — with `dir` the side the entrant came from, best-effort for teleport/shift), and `grab(me, state)` (fired when the player walks onto a `grab` thing — the only grab trigger).

 - `run_send(state, id, fn_name, arg)` — calls an arbitrary named function on an object (backs the `send()` action and scroll-choice dispatch). Picks the param list by the function's arity: 3 → `(me, state, arg)`, 2 → `(me, state)`, 1 → `(arg)`, 0 → `()`; a missing arg is `Dynamic::UNIT`. Errors if no function of that name exists.
 - **Reads** are methods/getters on the `api` types handed to the hook — `state.player.*`, `state.board.*`, `me.*` (see the `api/` section). There are **no read free functions** anymore.
 - **Write API** (`register_write_api`) — free functions that (mostly) enqueue an `Action` onto the **issuing object's** `queue` (resolved from the per-call tag): `move(dir)` (enqueues `Move` then a `MOVE_COST` delay), `delay(secs)`/`now()` (queue pacing), `set_tile(n)`, `set_fg`/`set_bg`/`set_color`, `set_tag(target, tag, present)`, `say(s)`/`say(s, dur)`, `scroll(lines)`, `send(target, fn [, arg])`, `teleport(id, x, y)` (jump entity `id` to a cell; `me.id` = self, `-1` = player), `push(x, y, dir)`, `shift([[x, y], …])`, `alter_gems(n)`, `alter_health(dh)`, `set_key(color, present)`, `die()`. **`log(s)` is the exception** — it is *not* an `Action`; it writes a line straight to the shared `LogSink`, so it surfaces immediately regardless of the object's queued delays (the write closure takes a `LogSink` clone). `scroll(lines)` takes a Rhai array whose elements are a string (text line) or a two-element `[choice_key, display_text]` (selectable choice). `shift` takes an array of two-int `[x, y]` arrays (a malformed entry logs an error immediately to the `LogSink`) and rotates that ring of cells via `Board::apply_shift`.
