Orkuncakilkaya 0f04b63516 fence: declared but unbounded, and a rewarm that keeps the warm-up's deadline 
Two blind spots from the windowed walk, where the heap grew about 1 MB a minute and the census read
`frames 0 bad 0 kept 0`:

- @alloc_ok memory was never held to its reason. Every R3D_ALLOC_DWIN judged frames (600) each site's
  declared bytes are set against their high-water mark: a new high adds to a streak, a flat window
  takes one off, a fall ends it. R3D_ALLOC_DRISE (6) is "declared but unbounded", said once per site
  with its line; fail mode exits 86. The census adds `unbounded N` and a `dsite` row per declared
  site by its growth since judging began. A list pushed forever grows by doubling, rising too seldom
  to make a streak; a record or text made every time (a re-mount's defaults) is what it catches.
- Mem.play() (every screen opened) restarted the warm-up, so memory kept every frame was never flat,
  the cap never came, and nothing was ever judged. A rewarm now keeps the first deadline, and past it
  has R3D_ALLOC_REWARM frames (120) of grace.

Goldens: alloc_fence_unbounded (a record a frame under @alloc_ok: exit 86, named, census unbounded 1);
alloc_fence_rewarm (kept every frame, Mem.play() every 360: judged and failed at frame 3000 - the
toolchain before this runs all 6000 frames and exits 0). alloc_fence_leak, _declared, _auto,
alloc_ok_private and the four arena goldens unchanged; the game's frame ratchets 0.

Examples

A curated tour of Ludic, grouped by intent. Every example here is exercised by the test suite (bin/ludic-dev test / bin/ludic-dev selfhost-test), so nothing in this directory silently rots.

Run any program straight from the repository root (so assets/ resolves):

bin/ludic build examples/games/snake.ludic              # compile + open a real window
bin/ludic build examples/games/snake.ludic --headless   # render one frame to build/out.ppm
bin/ludic examples/lang/offline_rewards.ludic     # compile + run a plain program

games/ — complete, windowed games

Example What it shows
games/snake.ludic A full game from primitives: input, grid, growth, collision, score.
games/menu.ludic A retained-UI title screen — the UI declared as data.
games/chronorift.ludic A 2D co-op JRPG: overworld, dungeon, random encounters, turn battle, boss, save. The entry file imports the modules under games/chronorift/.

rendering/ — drawing primitives

Example What it shows
rendering/draw_prims.ludic The extended Screen.* primitives — line, circle, triangle, fill, sprite.

ecs/ — the entity-component world

Example What it shows
ecs/hello.ludic The smallest program that exercises the ECS pipeline.
ecs/world_get.ludic Reflection: read/write a component by name.
ecs/world_scan.ludic Reflection: scan the world and identify each entity.
ecs/world_query.ludic Reflection: iterate the world by property.
ecs/world_spawn.ludic Reflection: a mod spawns a fresh entity by model id.
ecs/world_mixed.ludic Reflection: get/set through real struct offsets.
ecs/world_dyn.ludic Reflection: register a brand-new component at runtime.

events/ — the event bus

Example What it shows
events/events.ludic EV0: the event-bus core — declare, emit, @On.
events/mod_events.ludic Two listeners on one event, driven from a mod.
events/cancel.ludic EV3: cancellable (decision) events.
events/recurse.ludic EV6: re-entrant emit is depth-bounded — no runaway cycle.
events/promote.ludic EV1: @Public promotes a lifecycle hook to a public event.
events/prop_events.ludic EV1 for properties: attach/detach events.
events/scene_events.ludic EV1 for scenes: on-enter / on-exit events.
events/program_events.ludic EV1 for the program scope: start/quit events.
events/layer_events.ludic EV1 for layers + a public layer's show/hide events.
events/scoped.ludic A despawned entity drops out of subsequent event work.

networking/ — deterministic multiplayer (N0–N6)

Each maps to a stage of the Networking design; all run over the compiler's built-in loopback transport with zero foreign code.

Example What it shows
networking/net_echo.ludic N0: the transport seam.
networking/net_snapshot.ludic N1: whole-world snapshot to a memory buffer.
networking/net_sync.ludic N2: @Sync replication codegen.
networking/net_owner.ludic N3: entity ownership.
networking/net_rpc.ludic N4: remote events / RPCs.
networking/net_roles.ludic N5: handler roles + the drivable sim.
networking/net_demo.ludic N6: a networked game end to end, in pure Ludic.
networking/net_rt.ludic A blessed server-authoritative replication runtime.

lang/ — language & standard-library tour

Example What it shows
lang/annotations.ludic The annotation-first style: @Queries / @Computed / @OnSpawn / @Handles.
lang/qdecl.ludic @Queries desugaring to the query system.
lang/lifecycle.ludic The whole game lifecycle as @-hooks, in firing order.
lang/detach.ludic Structural attach/detach + @OnAttach / @OnDetach.
lang/reason.ludic Reason-carrying teardown (@OnDespawn: Despawned vs Quit).
lang/toggle.ludic enable/disable at the three ECS scopes.
lang/scenes.ludic One active scene at a time, handlers grouped into layers.
lang/strings.ludic Strings as values: compare, join, interpolate, slice.
lang/operators.ludic Compound assignment on every type, unary minus, char escapes, list literals.
lang/rng_demo.ludic The Random.* extensions (value/int/sign).
lang/time_demo.ludic Time.frame / elapsed / delta.
lang/offline_rewards.ludic A worked idle-game example over the Time/Date/Duration stdlib.

library/ — building and linking a shared library

A how-to for compiling a .ludic module to a native .dylib/.so/.dll and linking a second program against it via extern fn:

bin/ludicc examples/library/combat.ludic --shared -o build/libcombat.dylib
bin/ludicc examples/library/arena.ludic  -o build/arena -Lbuild -lcombat
Example What it shows
library/combat.ludic Exported functions callable across the C ABI.
library/arena.ludic A program that links against the shared library.
