- sendmsg/recvmsg with one SCM_RIGHTS fd and a sentinel byte; EAGAIN
parks in the net mould; the received fd arrives nonblocking as a plain
Int every fd verb accepts
- SO_DOMAIN gate: send_fd on anything but a unix socket refuses by name;
plain bytes deliver nil from recv_fd
- net.connect_unix carried here (iteration 38 still pending)
- legs (single-fiber: unix connect completes while the listener holds
the handshake): a pipe's read end crosses and still reads "ping"; a
tty crosses, term.raw works on the RECEIVED copy and destroy restores
it; refusal and nil legs verbatim. test_term 60/0

- mechanics amendment to the spec (recorded at close-out): no signalfd —
the stop-latch pattern generalized. An async-signal-safe handler
latches the number, bumps a sequence and pokes shard 0's wake eventfd;
wo_io_wait's loop head drains latches into fresh Signal{sig} records
delivered via runtime_notify (exported as wo_actor_notify)
- payloads must be heap objects (vm.c drops them unconditionally) — the
Signal record exists exactly for that; class id rides the call as the
appended record operand (sm_record drives it even with no return)
- offerable: WINCH/CHLD/HUP/USR1/USR2; SIGTERM/SIGINT refused naming the
stop latch; shard-0-only registration; coalescing disclosed
- stdlib_modules gains `signal` (and `term`, next task)
- test_term: a real child kills the test process with USR1; the actor's
multi holds one coalesced delivery; refusal leg verbatim. 14/0

- new docs/guides/updating-site.md: the developer loop deploying-site.md
deliberately does not cover — the submodule two-repo commit dance in
the order that cannot strand other clones (push writeonce-site first,
bump the pointer second), the gate living in the monorepo by design,
and framework changes being ordinary monorepo commits
- the schema section is measured against the built site, not inferred:
adding views: Int stopped the build with WO-E206 until all ten seed
inserts carried it (no field-default syntax — the seed cannot drift
from the schema), then the live WO_DATA migrated at boot, all ten
chapters rendered, and a live admin edit SURVIVED the migration;
retyping the field refused by name with the log intact
- states the one release combination that still needs the content wipe:
a schema change WITH new seed rows — migration handles the shape,
seeds still cannot reach a non-empty table
- deploying-site.md cross-links; site-update prefix registered

(cherry picked from commit 22b5675ed1c873135e8cb7dd10e010c4a00350b7)
- root cause: a worker's runtime is initialised lazily on first fiber
adoption, and rt.shard_id is stamped only there — but INBOX_READY[i]
is set at thread creation. A shard that never adopts is still settled
at shutdown, carrying rt.shard_id 0 from the memset
- it then impersonated shard 0: wo_drop_obj saw 0 == 0 for anything the
primary allocated, took the "we are home" branch instead of routing,
and called class_free against rt->classes, which lazy init never
filled. &rt->classes[class_id] off a NULL base is the faulting read
- fix: stamp the runtime's real identity at thread creation. An
uninitialised shard owns nothing, so its true id makes every payload
correctly foreign and routes it to an owner that can free it
- ASan could not name this: the arena is one hand-managed malloc block,
so intra-arena reuse is invisible and it surfaces as a bare SEGV
- pinned by tests/regress/lang-41, driven from db-actor-accept. Needs
multiple shards (the corpus runner pins WO_SHARDS=1) and the ASan
build. SEGVs twice per run unfixed, clean fixed
- the HANG is a separate defect and is NOT fixed: with this in place the
harness stops losing whole sections, but idempotent-stop-2 still
fires ~1 run in 6. The story records where to look

- records every decision made without stopping to ask, with what each
costs if wrong, since the SDD workspace is deleted on completion
- R9 is marked WRONG and overturned by R14: WO-E222 fires on the class
Pool, not on multi, so an actor can hold slots: multi PoolSlot. My
ruling shipped a README prescribing a permanent 1-actor pool
- R6 records that my own brief caused a security bug: trust_proxy with
an absent XFF collapsed every client onto one shared bucket
- R15 parks the one residual: pool_slots/pool_of have zero call sites,
so real N-actor sharding is compile-proven but gate-unproven
- measured the gate over 10 runs: it is NOT stably green. Most runs
fail idempotent-stop; one lost 6 checks with 000 status codes
- traces the flake to the C-runtime hang/segfault, now localised by gdb
to wo_arena_alloc / wo_str_new / vm_run

- bullet 2 wrongly told app authors to hold a bare actor handle and
re-wrap it as a forced ONE-slot Pool per connection -- that was my
own advice, not the previous implementer's, and the reviewer showed
WO-E222 fires on the class Pool, not on multi PoolSlot
- rewritten around the new pool_slots/pool_of pair: make_pool(n) once
at process start, multi PoolSlot held directly in connection-actor
state, a transient Pool rebuilt per use -- and states explicitly that
calling make_pool per connection restores the lost-increment race
- disclose that the gate's own ConnWorker fixtures still build a
deliberate one-slot Pool per leg, so no leg yet exercises real
N-actor sharding through pool_slots/pool_of
- soften the rate-limiting row: saturation-503 is gate-proven only via
Idempotent/pool_begin, not through Limiter's own try/catch arm

same key, different routes)
- 18g: capitalised key_header + capitalised wire header must still
dedupe (exec count, not status, is the load-bearing assertion --
pre-fix both calls answer 200 either way, but the handler reruns)
- 18h: same key on two different routes with include_body:false must
answer 200 then 422 (a digest mismatch, same as a body mismatch),
never replay route a's body under route b
- both legs run on a FRESH restart of the same binary, not piled onto
18a-18f's already-loaded server -- doing so measurably raised how
often this run hit the pre-existing, out-of-scope C-runtime
arena-allocator race (confirmed by gdb backtrace: SIGSEGV inside
wo_str_new, unrelated to this file's own .wo logic)

Room already holds directly -- this is what lets an app actually shard
across N actors per connection instead of a forced one-slot pool

- Add saturation leg (scripts/web-app-accept.sh): one-actor pool,
WO_MAILBOX=2, 15 concurrent requests, exactly 3 served + 12 answer
503; execution count matches the 200 count, retry-after + real
cause verified on the 503s
- Guard make_pool(n<1) by clamping in make_pool itself, not
pool_select's division -- that trap runs inside the middleware's
own try/catch and would be swallowed as ordinary saturation forever
- README: rate limiting + idempotency ledger rows moved to done,
scoped to what the gate proves; documented Handler-decorator
shape, Pool aliasing (WO-E222), call's scalar-only reply (WO-E226),
pool size as a capacity decision
- Story: Progress table filled with real hashes, 7/9 acceptance
criteria marked verified with citations, 2 marked verified by
construction (never gated even in the original plan), status: done
- Status board: standup entry, porch 1 pending row updated
- Recorded a pre-existing runtime hang (main() returns cleanly, OS
process sometimes hangs under concurrent call()-parked callers)
that also reaches the new leg's teardown; contained with kill -9
rather than asserted, so it can't flake the leg's actual subject

(cherry picked from commit 21934b18910070a3f24b8bd4367fcb9d397dc1fb)
- The nonce naming an ephemeral (4xx/5xx) row is handed to exactly one
call() reply and nowhere else -- no other message can ever construct
that key, so idempotent.wo deleting it right after building the Resp
is safe by construction (unlike the earlier shared bare-key row,
which a second message COULD reach and made deleting it racy)
- Closes the leak AND a real correctness edge: the nonce is
time.ticks() % 1_000_000_000, wrapping every ~1000s -- with rows kept
forever, a later failed attempt on the same key could land on the
same nonce and either collide with the unguarded insert or resurface
a stale replay, exactly what rounds 1/2 removed
- Gate leg 18f: N ephemeral attempts against the same key must return
IdempotencyKey's row count to baseline, not grow it by N -- confirmed
failing (baseline+N) against the pre-fix code, passing after
- N picked at 3: the pre-existing runtime hang/segfault (out of scope,
being tracked separately) reproduces more often at higher sequential
insert+delete volume against the same key; 3 stayed clean across
many runs while still proving the property precisely

(cherry picked from commit 9ad594748e01a665ccaf29733a48c2b83a2749da)
- Root cause of the residual: a 4xx/5xx row lived under the bare key,
so a second message could delete-and-replace it before the FIRST
caller's own middleware-side read (necessarily outside receive,
WO-E226) ever ran -- the owner itself could read back a LATER
message's answer, not just a duplicate reading a stale one
- Fix: a 4xx/5xx miss is never stored under the bare key at all. Each
such attempt gets its own row, keyed by a nonce carried back in the
scalar reply's low digits, so no other message for the same bare key
ever touches it -- the decision AND the row's identity are both
fixed inside the one serialized receive call
- Disclosed trade-off: that row is never revisited by a bare-key
lookup, so it is never TTL-pruned either -- permanent per failed
attempt, the same no-sweeper trade-off this codebase already makes
elsewhere, not a new one
- Gate leg 18e: reran 20x in isolation against the fix with zero
500-500 or 200-200 outcomes (was reproducible before)
- §18's SIGTERM-stop check now force-kills on timeout before clearing
$SRV, instead of matching §14/§17b's own gap where a still-running
process escapes the exit trap too -- an orphan no longer survives
past this leg regardless of the assertion's own outcome

(cherry picked from commit 464147a9ddf3a53cb1946637c3f517ba615ee358)
- Miss path only marks a response a durable replay target (outcome 1)
when status is 2xx/3xx; a 4xx/5xx gets outcome 3 instead
- Outcome 3's row is a one-shot relay: the scalar reply still can't carry
a Resp (WO-E226), so the row exists only to hand the exact response
back once, then idempotent.wo deletes it -- a retry with the same key
is a genuine miss and re-executes, instead of caching a 500 for the
24h default TTL
- Reviewer finding: caching any status meant a transient failure was
replayed verbatim until TTL expiry, worse than no idempotency at all
- Gate leg 18d: FlakyHandler fails once then succeeds; same key twice
must answer 500 then 200 -- confirmed failing (500, 500) before the
fix, passing after

- Delete before/after flow: it stored on a miss, so two duplicates both
missed and both ran; its 10s "in flight" check fired on fast legit
replays and never on a real collision
- Idempotent now wraps the route's Handler and hands request + handler to
the pool; a duplicate waits in the actor's mailbox, not a held reply
- keypool.wo kind-2 arm: digest match replays, mismatch refuses (422), a
miss runs the handler inside receive and stores status/body/
content-type, all via the same pool_pack(count, remaining_ms) scalar
kind-1 uses (WO-E226 forces one return type)
- Outcome codes start at 1, never 0: idempotent.wo's try/catch cannot
tell a literal 0 reply apart from a trapped call
- fresh_req() copies a borrowed Req's map fields into a new Req before it
crosses the actor boundary (WO-E222: aliased graphs can't cross heaps)
- Reading a stored row back forces fresh Text via `.. ""` on every field
copied out of json.decode's result -- decoded Text does not survive
being handed onward once the decoded record goes out of scope
- insert is unguarded (kind 1's own convention): a swallowed failure
would answer "stored" for a response never written
- web-app-accept.sh: leg 18a/b/c -- byte-identical replay off an ExecMark

- delete all RateLimitCounter access from limiter.wo: query, increment,

the only writer, so its serialization guarantee actually holds
- Limiter gains pool/limit/trust_proxy fields; before() calls pool_count

- key selection: req.principal first, else trust_proxy ? client_ip(req)

- keypool.wo:78,89 passed msg.window (µs) straight into pool_pack's
remaining_ms (ms) parameter on the first-hit and post-prune-reset

- fix: pool_pack(1, msg.window / 1000) at both sites — a 60s window
no longer reports reset_at ~16.7h away
- count/allowed were unaffected (computed independently); this only
hit the client-visible reset instant, on the two most common cases
(new key, window rollover)
- extended gate leg 16 to assert reset_at falls within a 5s band of
time.now() + window_ms, not just on count — verified the assertion

"call's reply type `Out` is not a copyable scalar"
- the spec had the actor return the response object, which cannot cross
the mailbox. Corrected: the actor stores the response and returns an
outcome code; the middleware reads the row and builds the Resp
- owner and duplicate now read the SAME durable row, so byte-identical
replay is structural rather than careful copying

- KeyActor.receive implements kind 1: reads the row, writes the new

prunes a fully-elapsed window's row instead of resetting it
- window arithmetic on time.ticks(); reset instant sent back is built
from time.now() only
- call's reply must be a copyable scalar (WO-E226), so the count and

(cherry picked from commit 676e651d808ef2c3619f88c3808adc372cd0be6c)
- Add digest field to store sha256(method|path|body) separately from key
- Enables detection of "same key, different body" in future tasks
- Update idempotent.wo insert to compute and store digest value
- Typechecker passes: exit 0

(cherry picked from commit 3a9bddcd1e3c11f5b371ce54cafc373685ca08b6)
- one message class with a kind discriminator, not a receive per
message type: an actor handle is typed to one message class, so a
second receive compiles but is unreachable. chat/main.wo is the
precedent. Verified by fixture before amending
- Task 4's Files list omitted keypool.wo, which its step 4 edits
- clarified that the delete-then-insert ban targets using that pair as
an UPDATE; pruning an expired row is a plain delete and is required

(cherry picked from commit a96ebe20e92e2dc6dfecc59a955d4c6e75d74689)
- the spec's blocking design was unimplementable: call's reply IS the
return value of receive, so an actor cannot hold a waiter. Holding
means never returning, and an actor that never returns cannot process
the completion it waits for — deadlock
- corrected shape: the actor RUNS the handler inside its own receive, so
a duplicate waits in the mailbox and is served after the owner. The
queue blocking needs is the mailbox; nothing is held
- verified before adopting it, not after: an actor can receive a message
carrying an interface-typed value and invoke it, so the route's
Handler passes through the mailbox
- spec History records the reasoning error — "the primitives landed" was
taken as "blocking needs no new surface", which does not follow
- plan: 5 tasks. Counting and replay live in one new keypool.wo; both
middlewares become thin key-choosers, so porch 2 and 3 inherit one
serialization convention instead of re-implementing it
- self-review added two legs it was missing: exact counting under real
concurrency (the criterion the pool exists for), and pruning an
elapsed limiter row rather than resetting it, which otherwise leaks a
row per IP ever seen
- plan is code-free per house convention; the writing-plans skill wants
code blocks and the project rule overrides it

(cherry picked from commit f079455755a189a86bb12e07cc11549ed7a78b91)
- docs/examples/porch/ did not typecheck: WO-E403 "cannot resolve the
receiver's type for the call to `encode`" on json.encode
- every other example that calls json.encode/decode imports it; this
file did not, so the whole porch library was uncompilable on dev
- woc docs/examples/porch/ now exits 0

(cherry picked from commit 5c3544d524fa98dbb7a363600cd2eeb6dd1badac)
- supersedes Phases B and C as built: a store-after-completion
middleware cannot satisfy three of the story's seven criteria
- in-flight collision is undetectable (the row is written after the
handler ran, so concurrent duplicates both miss and both execute)
- the 10s in-flight heuristic is inverted: created_at is stamped at
store time, so it fires on legitimate fast replays and never on a
genuinely concurrent request
- "reused key, different body is refused" is unreachable while the
digest is folded into the key — nothing looks the bare key up
- design: sharded actor pool serializes per key, @table persists;
actors own volatile state, tables own durability. Inherited by
porch 2 and 3
- limiter joins the pool for exact counting, writes through instead of
delete+insert, keys on net.peer unless trust_proxy is declared, and
uses monotonic ticks for arithmetic but wall clock for the header
- idempotency blocks rather than answering 409: call parks the
duplicate until the owner reports. Digest becomes a column
- saturation fails closed with 503 for both: saturating the pool must
not become the limiter bypass
- records that the story's "time.after is still reserved" is stale;
spawn/send/call/monitor/time.after all landed

(cherry picked from commit fc09e94373db65837ff5eb620fec67bab02c1931)
- Idempotent middleware (aee7926) added to the porch-store row
- records that Phase C is unverified: no `use json` import despite
calling json.decode and json.encode
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
(cherry picked from commit aa8abfb4b7a1dabaa0c68afa0ee7fdfccf1b4689)
- replays a stored response for a repeated Idempotency-Key: before()
checks the key, after() stores status/body/content-type on a 2xx/3xx
- key is "idem:<header>:<value>", optionally plus a sha256 digest of
method|path|body when include_body is set
- 409 while a key is in flight (stored within the last 10s), lazy TTL
expiry on access, default 24h
- replay allowlists content-type only — never Set-Cookie or Date
- backed by IdempotencyKey from Phase A (519d411)
Written by a parallel session and committed here as-is because its
branch was consolidated away. NOT verified: it calls json.decode and
json.encode without a `use json` import, which every other example that
uses json has. Left unedited rather than fixed blind.

(cherry picked from commit aee79264095eea3b2c38c92789c44b31f1c9ef8a)
- porch-store and query-corpus prefixes registered; both replayed onto
dev, so dev is a superset of porch-store-middleware
- three branches could not be replayed and are preserved as annotated
tags rather than merged or discarded:
- cleanup/pre-existing-changes carries crates/ + Cargo.toml, the Rust
runtime master deleted; replaying it would resurrect it
- ipc-attach refactors wo_row_insert/wo_row_update_field into
encoded cores, which db2-keys rewrote for keys-residency — two
overlapping refactors of one function
- keypair-auth builds on ipc-attach, blocked by the same overlap
- names the specific hazard: 9c transfers ownership of vals on failure,
dev's keys-resident arm returns early without freeing, so a merge
that compiles and passes could still leak or double-free

(cherry picked from commit bc8fec01d565d0ad54696fb3d2f85a9d1e0531a1)
- resolved 9g's forks EMPIRICALLY against the running compiler:
- count(<query>) and len(<query>) already work (fork 2 collapses to
zero code)
- skillhost's correlated NOT EXISTS is a backlink emptiness in
writeonce (`where len(x.children) == 0`), using only 9b machinery
(fork 1) — verified on a self-referential ?ref/backlink table
=> corpus #1 forces NO new grammar; per the method ("add only what a
corpus uses"), exists/not-exists was NOT built
- docs/examples/skill-catalog: mirrors skillhost's `skills` table
(name @unique, description/location/root, parent ?ref Skill, children
backlink) and translates all five of its SQL statements 1:1
(insert+dup-trap, get-by-name, list, roots via backlink-emptiness,
count); scripts/skill-catalog-accept.sh 7/0, WAL-durable, dup trap
persists across restart
- fixture run/db-query-corpus (count(query) + backlink NOT EXISTS);
just skill-catalog module; target/ gitignored
- general exists/not-exists left unbuilt and recorded as "enters when a
corpus forces a non-relation correlation"
- gates: oop-e2e 80/0, woc-test 566/0, skill-catalog 7/0; story + board
record the finding

(cherry picked from commit 4c82461634d45f11eca1a252702031c03d999c7f)
- story frontmatter status: done, Progress section records what landed
vs the spec (everything, same day as the brainstorm)
- board: NEXT PLAN entry with the six standup answers (deadlock proven
real: 5 s hang, 8192-byte truncation; 15 ms after; ping 2 ms during a
parked child; 1000 spawns fd-flat; SIGTERM leaves no child); pending
row flipped to DONE
- graph: node 42 class done, same change as the board row
- runtime/src/CODE-LOGIC.md: the bounded-subprocess section (bundle
park, slot registry, ownership sweeps, raw pidfd syscalls)
- full belt at close: 19 runtime suites 0 fail (test_proc 128/0),
woc-test 557/0, subprocess-accept 12/0, site-accept 23/0

- docs/examples/subprocess: line-oriented TCP service, one Handler actor
per request — ping/run/slow/deadline/cap/long exercise the whole
bounded surface from .wo, traps caught with try/catch in the language
- scripts/subprocess-accept.sh + `just subprocess`: 12 checks, 0 failures
first run — deadline and cap messages verbatim, ping answered in 2 ms
while a sleep-2 child was parked, SIGTERM exit 0 with the sleep-30
child verifiably gone (pid checked from outside)
- service logs to /tmp/subprocess.log, banner-separated per run

- one stdlib_members row (arity 5, id 96, nullable Proc return, Proc
record class appended) — the net _dl precedent verified: those rows
needed no emit.ml change and neither does this one
- woc-test: 557 checks, 0 failures

- ceiling: 32 fibers hold live sleepers; the 33rd spawn traps WO_T_IO
naming the ceiling; destroy sweeps all 32 (waitpid -1 = ECHILD after)
- unwind: a fiber parked on a live child is reaped at main's return and
the child dies with it (nchildren 0 straight after the call)
- churn: one thousand sequential `true` runs through a bytecode loop —
fd count flat, every slot released
- stop: SIGTERM from a helper 200 ms into a sleep-10 child answers rc 1
(STOPPED) with no surviving child
- test_proc 128 pass 0 fail in 2.6 s, suite ASan clean
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- proc.run_dl reachable: dispatch range extended to id 96 (builtin.c) and
the loader arity table gains [WO_B_PROC_RUN_DL] = 6 — without both, the
builtin answered "unknown stdlib builtin" (WO_T_EXPLICIT)
- deadline leg: sleep 10 vs 100 ms deadline traps WO_T_IO naming the
deadline in ~120 ms; the pid is gone (waitpid -1 = ECHILD) and the fd
count is flat; a worker fiber completes WHILE main is parked — the
shard was never blocked
- cap legs: stdout and stderr caps trap naming "cap 1000", child dead
- argv multi carries a drop entry at the run pc: a trapping run frees it
(LeakSanitizer caught the miss)

- deadlock proven first: chatty child (200 KB stdout, stderr held open)
hung the old sequential drain 5.0 s into the alarm, code -1, stdout
truncated at 8192; the leg demands completion under 4 s
- rework: nonblocking pipe read ends + pidfd_open behind one epoll fd the
fiber parks on (the _dl retry mould); both pipes drain on readiness, so
the deadlock is gone structurally — leg passes in 15 ms
- wo_child slot table in wo_vm (32/shard) carries cross-park state; caps
refuse by name (kill + WO_T_IO), deadline armed via dl_active/dl_at,
defaults 30 s / 1 MiB / 64 KiB
- WO_B_PROC_RUN_DL = 96 shares the case (per-call deadline_ms/out_cap/
err_cap; compiler row lands in a later task)
- fib_reap kills a reaped fiber's child; wo_vm_destroy sweeps the table
- raw syscalls for pidfd_open/pidfd_send_signal: glibc 2.35 build floor
has no wrappers
- all 19 suites green under ASan+UBSan

- new suite runtime/test/test_proc.c (auto-globbed by the Makefile)
- three legs against today's behavior: echo exits 0 with exact stdout,
false exits 1, a missing command answers 127 (the execvp convention)
- record fields copied out before the vm dies; ASan clean
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- seven commits dev to master, zero conflicts: the six db2-migrate
commits plus site-deploy, which the close-out edits and which had
been dev-only
- verified on master after the pick: 36 suites 0 fail (test_wal
5966/0), woc-test clean, residency-accept 14/0, site-accept 23/0
