A frame holding a new peak of facts made a record and grew the free list; now nothing is made until
64 are held at once. The two record-count tests hold the 64.

ludic deps --allocs (25.2) found phys_float's five pushes per drop reaching the water and
phys_sink's filtered copies per removal.

ludic deps --allocs (25.2) found npc_pick_name making a list of the body's names at every spawn and
np_left making a new list of the recent names at every retire.

@alloc_ok with its reason on what is made once per resource and kept (textures, programs, samplers,
views, layouts, memory blocks, the pipeline cache in gvk_pipe_build), on resize and swapchain
remakes, on screenshots and dumps, on a world being set up (streams, layers, water, post, bakes), on
loads (gltf_load, skin_load, tex_load*, png_decode, fonts) and on R3D_PROF / drawstats.
gltf_cached's hit path is its own and makes nothing; the miss (gltf_cached_load) is declared.
m4_look_at (now over m4_look_at_xyz) and m4_inverse work on scalars, and cam_update makes no scratch.
Left: lazy first-use starts, error and debug prints, and scratch made and freed each call (churn,
plan 25.3). Compiled (steady, and ludic deps over the game).

gvk_pipeline_fast's miss (the build and the six cache pushes) is its own function, so the fence can
declare it: @alloc_ok("pipeline cache: one per variant the game draws") once lang/memory-fence's
compiler is merged (the annotation is not known on this base). Compiled.

Jolt's Allocate/Reallocate/Free/AlignedAllocate/AlignedFree go to libc's malloc with the size in a
16-byte header, and atomic counters keep live bytes, the peak and the blocks asked for (its job
threads allocate too). The fence reads the three exports extern_weak to judge Jolt by its plateau.
jolt_heap_test: a ground in and out 1100 times holds 46,482,514 bytes after the first 100 and after
all of them, the peak does not move, and a closed world gives back every byte it took. The macOS
library is rebuilt; the Windows DLL still has to be rebuilt on the PC.

Plan 25.1c: vk_mac.ll's @lvk_ac (posix_memalign under a 16-byte header of scope/offset/size, atomic
counters) passed at every render3d create/destroy (49 sites; the caps probe keeps its own null pair);
lvk_ac_bytes/_peak/_allocs/_scope_bytes for the fence, Vk.alloc_bytes. vk_win.ll: null and 0.
MoltenVK 1.4.2 counted 0 live bytes through them in steady. Fence findings: gvk_pipeline freed its 17
create infos (and reuses one bufs list); actor_init fills ac_spare with 512 records (actor_fresh,
m4_new, v3_new at first placement in play). Compiled, not run (the user's call).

The fence found np_fact_record making a record in five frames of every scenario: the pool grew to
each new peak of facts held at once, and q_unheld's free list and the queue's two lists grew with it.

A prompt that comes and goes as a player walks (co-op's netleak: in_get, cmp_*_new, bd_class, value_slot/put)
made a new record, props and model on every mount, and an action's call answered into a new Val (ev_call_with).
examples/library/ui_remount: two thousand comings and goings hold the heap at 0, and the counter starts at 0.

An event was a tree of values encoded into a new string, a dropped line was never given back, and
every batch and save joined the queue into another. Now: telemetry_props / telemetry_str / _int /
_bool write the properties as JSON into a buffer the state keeps; the line is written beside it,
its time worked out from the clock's seconds (TelemetryWorld.clock_s, was stamp); its bytes go
into one ring (ring_bytes, at most queue_max lines), the oldest overwritten past either; a batch
and the file are written into a third kept buffer and go as bytes (TelemetryTransport.send takes
the bytes and their length; Http.body_bytes, Fs.write_bytes). The facts are pooled.
tests/ring_test: ten thousand events past the cap in lines and in bytes, 0 bytes of heap; the line
exact JSON, escaped, 2000-02-29 right; the batch puts the id in; the file round-trips.

A co-op guest loading its models segfaulted in copyBufferToBuffer under vkQueueSubmit (0x68, AGX
LegacyBlitContext): a buffer primed into the frame's command buffer was released later in that
frame, and gvk_buf_release destroys a buffer no draw has marked, so the copy read a freed one. The
copies now run in their own command buffer before the frame's begins, checked against the slot's
handle as they are recorded.

A chunk's trunks and boulders put in and taken out made a new shape each time and freed none. The
table is by the body's index, made once at the world's size. tests/reuse_test: 1000 owned bodies put
and removed hold no more shapes and 32 bytes of heap.

lp_os_platform and lp_os_arch malloc'd 8 KB per call (the uname buffer) and kept none of it:
string_temps now asks both every round, 327 MB over 20,000 before, 0 after. Reseeded. render3d:
MoltenVK made a mapped buffer's MTLBuffer at its first bind (fn_gvk_draw +4 blocks in the boat
window); gvk_buf_reserve queues it and the next frame's command buffer copies 4 bytes out of it.

stream_update made a Chunk and a words copy per new chunk (fn_stream_update +39 blocks / 13.2 KB a
window with the hiker in the drifting boat). The pool holds STREAM_MAX_CHUNKS records; the arena
is twice the layer's cap; eviction compacts it; a chunk that cannot be kept is gathered from the
scratch. stream_clear_all frees records, lists and streams. steady: 300 new cells, cap 256: 156 KB
before, 0 / -4.9 KB after, and every kept chunk's data checked against its cell.

np_queue made a NetMsg and a buffer per message, every flush a new keep list, and every message
that came in a NetMessage and a buffer; nr_text a new string per text read. A party plays at
dozens a second, so all of it is kept now: a pool of MTU-sized records for the queue (a peer's two
lists swapped by the flush), the inbox's records in two halves swapped when a message finds the
inbox empty, net_written's one record, a relay hello's and a STUN request's bytes in one scratch
buffer, and the texts read out interned. Tests: 6000 messages with the heap flat (Os.heap_bytes),
and an inbox record that holds still across a drain and comes back two drains on.

tests/reuse_test: 200 walkers made and removed hold one place and 0 bytes of heap (Os.heap_bytes);
twenty closes and opens keep the same shape and walker lists.

The pools kept every command object ever recorded, so the heap grew each time a frame drew more than
any before (fn_gvk_draw under vkCmdBindVertexBuffers/BindIndexBuffer/Draw in the leakcheck; ~650 B a
draw). Off: 3.7 ms a frame either way over 520 actors. steady: 20 to 200 actors grows 5-7 KB with it
off and 120 KB with it on (bound 16 KB).

th_fact made a ThingFact per placement, removal and use, and the valley places and removes Things
all day. The records come back two drains after they were handed out, so a reader placing a Thing
while it reads the last drain's list never sees one change (the test holds exactly that).
thing_use takes ThingsState mut, since it pushes a fact.

No bake and no new file: the skeleton comes from the skin's parents and rest pose (its own joints
and their ancestors - a kit holds several rigs), a clip from anim_read_doc's channels. Built by
native/build.sh from the pinned release; the Windows DLL imports KERNEL32 alone and passes there.

gvk_tex_storage freed none of ici, out, req and vci (8 blocks a two-texture model); tex_load_ex kept
dds_path_of's string. Found with malloc_history over 400 load/release rounds (712 bytes a round, all
of it these). steady: the model's bound is 4 KB over 200 (was 1.6 MB), and the frame is the least of
three settled windows - a valley self-test beside it read 87 KB once.

A freed texture or buffer id goes on a spare list the next one takes; tex_note_size keeps sizes by id.
model_release frees prims, meshes, material names, the skin and leaves gltf_cached. actor_release
takes an actor off the stage and actor_new reuses its record (ECS's Things come and go all day).
steady.ludic: an actor round at 0 bytes over 2000.
