- Mixer actors: 90/10 read/write, per-actor histograms merged through
the store itself (Hist rows) — exact aggregate percentiles
- msgrate: one-way flood at a worker-placed sink; measured 15.3M
msgs/s same-heap vs 2.06M cross-shard — the mutex-inbox number
- finding: point lookups are O(table) (probe walks all slabs), so
read-heavy mix is quadratic in store size — all-mode calibrated to
N/10 mix ops; the number 22 exists to publish
- TSan clean both shard counts (setarch -R, fibers-gate pattern)

- Meta expectation rows ride the same WAL verify checks
- finding: hand-built multi<TableClass> SEGVs on drop (elems classed
OWNED, refs are scalar ids) — worked around, recorded
- finding: reads ~1.6k/s p50 595us vs 287k/s inserts — probe walks

- worker DB builtins marshal to shard 0: requester-side slot encode
(VM heaps never read cross-shard), owner executes serialized in
adopt, reply unparks via new WO_PARK_INBOX park + envelope 3/4
- engine gains thread-agnostic slot entry points (insert_slots,
update_field_slot, val_encode/clone, wo_db_exec_req); traps and
messages byte-identical to the local path
- main.c: engine + replay boot BEFORE shards spawn; workers assert
rt.db/rt.wal NULL; busy shard adopts inbox once per slice
- latent stage-1 bug fixed: shared io_uring params static raced by
lazy worker init lost park wakes (~1/20 hangs); params per-vm,
short submit now fails loud
- new sample docs/examples/db-actor + just db-actor gate 8/0 (multi

ASan+TSan 6/6; full battery green

ack-after-owner-fsync, workers WAL-free + replay-before-serve,
no torn reads under TSan corpus); arc plan stage 3 carries them
- refine/32-wal-checkpoint.md: snapshot + truncate, bounded replay,

- Float full stack: literals (fraction/exponent; `0..10` still a range), f64
opcodes 34-41, @table column, WAL bit-exact replay, json fractions in and
shortest-round-trip out. IEEE-quiet — FDIV never traps where DIV does.
- Bytes: a wo_str with its own class id, so alloc/free/copy are shared but no
Text builtin accepts one; len/at/slice/eq/concat, base64 both ways, json
boundary as base64; TEXT_COPY preserves the kind.
- No implicit Int/Float mixing (WO-E201 in the typechecker, not the emitter,
which picks the opcode from one side and would misread the other).
- One IEEE deviation: float_cmp total order (NaN last, -0.0 == +0.0) for
indexes and order-by, keys canonicalized to match. `?Float` nil is a
reserved quiet NaN — the zero word is +0.0, WO_NIL_SCALAR's bits are -2.0.
- Renderer prefers fixed over exponential in 1e-6..1e21: pure shortest makes
a price of 900.0 read `9e+02`. One renderer for interp/json/float_to_text.
- Fixed en route: lexer double-counted the leading digit; is_scalar_shaped
took Float/Bytes as Int-shaped; Bytes ownership needed a shared heap-scalar
predicate or temps never dropped; order-by bit-compared negatives backwards.
- Iteration 17: `kind = "library"` (absent = program; bad value = WO-E109),
entry-less check mode retiring the `--emit` workaround, Go's `internal/` as
WO-E108 at the consumer's `use`. Driver-only; VM/.wob/GC untouched.
- Framework reorg: internal/{parse,serve}.wo; http/form.wo split out to keep
media_type/form_values public (parse.wo had grown public surface).
- Docs: link audit (97 -> 88 broken, conflict markers resolved, 2 duplicate
stories removed), 00-code-review verified 26/27, iterations re-sequenced.
- Also carries the pre-staged pub(read)/using/#if work from the index.
- Gates: corpus 103/0, test_wal 156/0, web-app 26/0, oop-accept ALL MET.

- developer directive: pending iteration IDs now ARE the priority order;
LANDED iterations keep historical numbers (code comments and commit
history cite them — records, not a queue); 8/11 (the half-landed
arc), 17 (parked, artifacts on a branch), 18 (next, artifacts named)
also frozen
- mapping (recorded in 00-story): 19<-20 Float+Bytes, 20<-9c attach,
21<-9d keypair, 22<-9e benchmarks, 23<-9f io_uring WAL, 24<-19 chat,
25<-10 services, 26<-12 blue-green, 27<-9g query corpus,
28<-14 skillhost, 29<-13 metaprogramming
- 11 story files renamed; every doc reference re-numbered (word-boundary
sweep for the lettered 9x ids, phrase-level for numeric ones); the
iterations table rewritten with Seq == priority and "(was N)" notes;
story-scoped link check: zero broken
- merge-recovery folded in: the partial master merge had dropped the
chat story, the fibers exploration note, the arc spec+plan, the
framework-v2 plan, and the iteration-17 spec+plan — all restored from
their branches and renumbered consistently

- brainstorm settled four forks: Float FULL STACK in one iteration
(literal, IEEE f64 VM ops via u64 bitcast, @table column + WAL slot,
json fidelity — json.c's own comment names the hole: fractions are
malformed because "the language has no [float]"); IEEE-754 QUIET
semantics (division never traps, NaN flows; Int keeps DIV0; no
implicit mixing — float(i)/trunc(f) bridges); BYTES ships alongside
(binary carrier: multipart files, WS frames for 19, crypto digests;
Text goes back to meaning text); iteration 20 + spec before code
(.wob/WAL version bump earns a written spec)
- the rest of the missing-type survey recorded with reasons: Result/
Option expressible today (?T + payload unions), tuples covered by
records + doctrine, Decimal stays cents-until-a-workload, Char/
Unicode its own future story, Set/ADTs parked post-12, scalar
newtypes need the rejected `abstract`
- one indexed-storage deviation from raw IEEE spec'd loudly: a Float
index needs a total order — NaN sorts last
- board row, story-table row (seq 26), graph node (9+16 -> 20 -> 19;
crypto gate wants Bytes)

- spawn placement: round-robin across shards (same-shard when the
engine is absent/single); the actor's mailbox and delivery belong to
its HOME thread — a spawn to another shard travels as an ADOPT
envelope, a send as a SEND envelope (mutex-guarded inbox + eventfd
wake; the spec's lock-free rings stay a disclosed deviation until
9e measures the mutex)
- workers: first envelope triggers lazy full-vm init UNDER the inbox
mutex (TSan caught the memset racing a concurrent push, twice — the
second was inbox_push reading wake_efd outside the lock; both fixed,
gate x8 + battery clean); serve loop = adopt -> run to drained ->
wait on the plane (the wake eventfd is watched by io_uring POLL_ADD
oneshot / epoll level-triggered on BOTH backends)
- ownership across heaps: every allocation stamps rt->shard_id into
the header (the field reserved since iteration 2); a drop on the
wrong shard routes home as a FREE envelope — the owner's arena stays
single-threaded by construction; at teardown routed frees become
no-ops (arenas die wholesale) which is what un-danced the freed-mutex
ASan SEGV the first ordering had
- WO-E222: an actor's state or message type that is (or transitively
contains) an inferred-traced class refuses at the spawn/send — with
round-robin every actor is potentially remote; corpus-pinned
(compile-fail/traced-send, inference-aware: Box contains ?Node)
- determinism narrowed per spec: oop-e2e pins WO_SHARDS=1 (exact
outputs); the fibers gate grows multi-shard SET assertions + a TSan
run (wovm-tsan target; setarch -R fallback for kernel 6.5+ ASLR)
- NEXT_RUNNABLE honors engine shutdown for parked workers (deadlock
hole closed); io_wait's adopt-wake (rc 1) no longer reads as fatal
- battery: oop-e2e 93/0, fibers 10/0 x8 (+WO_IO=epoll), log-watcher
7/0, employee 8/0, web-app 21/0, deps 8/0, runtime tests 16/16

- wo_engine + wo_engine_start/stop: one pinned pthread per extra core
(pthread_setaffinity_np); shard 0 is the primary (entry + database);
workers idle on a wake eventfd until fibers arrive (T6) or shutdown
- default = all cores (the arc's brave landing), WO_SHARDS=1..64
overrides; N=1 spawns no threads — byte-identical to stage 1
- worker vms are LAZY: identity + wake fd only until their first fiber
arrives — 20 idle shards must not cost 1.25 GiB of eager arenas
(they did: the web-app gate flaked on exactly that before the fix;
3 consecutive green runs after)
- engine stops (join + destroy) before the primary's teardown
- battery at the 20-core default: oop-e2e 92/0, fibers 8/0,
log-watcher 7/0 (+WO_SHARDS=1 identical), web-app 21/0 x3,

- docs/examples/fibers: part 1 is TIMING-FREE and byte-exact — main
sends three messages then burns reductions; each budget expiry hands
the Counter actor exactly one delivery (cooperative mechanics,
preemptive fairness, BEAM's shape); part 2 parks a Sleeper actor
mid-receive on the I/O plane while main keeps ticking — the wake
lands between ticks, proving a sleeping fiber blocks nobody
- the missing "sleeper: up" on the first run was main-return-reap
working as specced (main ended before the deadline); the demo's
window widened so the wake is observable
- scripts/fibers-accept.sh + `just fibers` (8 checks): build, part-1
exact + part-2 ordering invariants on auto/uring/epoll backends,
and an ASan-runtime rebuild+run
- README points at the doctrine writeup (exploration/fibers)
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- park.c/park.h: one event loop per shard. io_uring PRIMARY (raw
io_uring_setup/io_uring_enter, uapi structs mirrored, 5.4-floor ops:
POLL_ADD for fd readiness, TIMEOUT for sleeps, user_data = the fiber);
epoll+deadline-scan FALLBACK behind the startup probe; WO_IO=
uring|epoll forces either so CI proves both on one kernel
- park protocol: a blocking builtin fills cur->park_* and returns
WO_SYS_PARKED; resume either RE-EXECUTES it (fd readiness: accept/
read/write retry) or continues PAST it (sleep: result preset,
park_done=1 — re-executing would restart the full duration)
- sysio: listener + accepted fds nonblocking (accept4 SOCK_NONBLOCK);
accept/read park on EAGAIN; write parks on EAGAIN with its partial
progress carried across the retry in park_wr_at; sleep parks on a
deadline — with ONE fiber the plane's wait IS the blocking call,
program mode is the degenerate case, not a special one
- scheduler: NEXT_RUNNABLE waits on the plane when the queue empties;
a stop interrupting the wait reaps EVERY fiber (queued and parked)
and returns the clean-stop status; parked fibers are GC roots and
fib_reap_all drains them
- proof: full battery green on the uring path (oop-e2e 92/0,
log-watcher 7/0 incl. the mcp accept/read/write loop, employee 8/0,
web-app 21/0, deps 8/0), WO_IO=epoll battery green (log-watcher 7/0,

flatness holds over parked I/O)

- language: `spawn Cls { fields }` expression (ctor semantics — fields
MOVE; result is the address); `actor M` parametric field type
(contextual like multi/map — actor stays a legal identifier); `send`
is a builtin free-fn name, not a keyword (shadowing rule applies)
- typing: M inferred from Cls's receive(msg: M); WO-E221 when receive
is missing, mis-armed, or M is not a class/record/union; send checks
addr is `actor M` and the message IS an M (silent when underivable);
ctor half of spawn delegates to the Ctor arm (completeness, ?T, E207)
- ownership: send's message TRANSFERS (sender's later use = WO-E301,
corpus-pinned); spawn's fields move via the ctor machinery; an
address is Copy
- emit: spawn lowers to ctor + LOADK receive's method index + BUILTIN
68; send is BUILTIN 69 with the message excluded from fresh-arg drops
(the runtime owns it now)
- runtime: wo_actor (moved-in instance, receive idx, growable FIFO
mailbox, one delivery fiber at a time); delivery reuses the fiber
context across messages and re-queues per message (fairness — an
actor never monopolizes); the runtime drops each message after its
receive returns; actor state/queued/in-flight messages are GC roots;
teardown drops everything (main-return reap included); loader knows
the two arities
- corpus: run/actor-echo (typed spawn/send, one-at-a-time delivery
interleaved with main by budget — output exact, ASan-clean),
compile-fail/spawn-no-receive (WO-E221), send-after-move (WO-E301)

- fiber states (RUNNABLE/PARKED/DONE), intrusive FIFO run queue,
wo_vm_spawn_fiber (calloc'd context, frame 0 set up like wo_vm_call)
- reduction budget: WO_REDUCTIONS (default 4000), checked at loop
BACK-EDGES AFTER the jump lands so the saved pc is the loop head —
a pre-instruction save at budget 1 re-executes the jump into the
same decrement and livelocks (found by reasoning, pinned by the
budget-1 test; deviation from the spec's three-site wording,
recorded in the yield macro's comment)
- FIBER_DONE: main returning ends the program and reaps every
remaining fiber through vm_unwind (drop maps run); a spawned fiber
ending frees silently; its return value is discarded by contract
- TRAPF: an uncaught trap in a spawned fiber kills that fiber ALONE
(stderr report, program lives); in main it stays the program's death
- WO_SYS_STOPPED reaps all fibers wherever it lands (main unlinked
from the queue and unwound if a spawned fiber caught the stop)
- vm_gc_roots walks the live fiber plus every queued one
- test_fiber (45 checks, ASan): EXACT round-robin interleave at budget
1 across three fibers pushing tags into one shared multi;
main-return reaps a spinning fiber holding an owned Big (ASan proves
the free); a DIV0 fiber dies alone, main answers 0

- wo_fiber = the interpreter state wo_vm held inline: register window,
frame stack, catch stack, caught-error slot; wo_vm keeps module,
runtime, the embedded fiber 0 (main) and the cur pointer every

- emit_return's place test matched only bare Ident/Field/Index, so

Ident/Field/Index behavior at return unchanged

- set_header(mut r, name, value) — the builder escape hatch
- web-app registers through the helpers (dogfood); README documents all
- gate grows 14 -> 16: 405+Allow, HEAD-vs-GET content-length equality
- all gates green: web-app 16/0, woc-test 540/0, oop-e2e 89/0,
deps-accept 8/0, log-watcher 7/0, employee 8/0
- board/story: iteration 17 parked (spec+plan ready on library-internal),
16 carries the v1-polish landing, order list updated

- copy_place_text matched only bare Ident/Field/Index, so a Text-typed
single-segment interpolation ("${r.method}", r a loop borrow) passed
the place's own register through a binding/assignment boundary — the
local aliased the row's field and its overwrite freed it
- release-build crash; invisible to ASan (in-arena free, no redzones)
- now asks is_borrowed_value_t && not is_container_read — exactly
drop_fresh_text's place test; Int segments (fresh int_to_text) and
container reads (already copies) stay uncopied as before
- pinned by tests/corpus/run/interp-borrowed-field (crashed both
runtimes before the fix, 50 iterations now exact)
- gates: woc-test 540/0, oop-e2e 89/0 (ASan stage included)

- NEXT PLAN step 1 now carries the reason: 17's edit targets (framework
sources, [deps] resolution in main.ml, just web-app gate) exist only on
the web-framework branch; unmerged start = branch stacked on unreviewed
branch
