- the motivating workload was an audit log, which is append-only and so
argues for nothing. A catalogue is the real case: stable ids, and
stock moving on every order while name/price/sku sit still
- Product (durable, resident: all) and Cart (durable: false), with
place_order decrementing stock through a write-through field assign
- run `order` twice and stock goes 10 -> 7 -> 4: a level below the
seeded 10 can only mean an earlier order's UPDATE replayed. That is
the stronger claim — not just that inserts survive, but that a field
change does
- caught by running it three times: my first assertion required
before == 10, which only holds on a fresh seed and failed on the
third run even though the data was correct
- gate gains a leg for the update-replay claim; residency 12/0
- the commented resident: keys block now argues the DESIGN too: only
stock changes per sale, so appending the whole row would rewrite
every field to move one integer on a shop's hottest write path

(cherry picked from commit d4104dcc5e3a460459dbf2d24043ce25b113bcdf)
- docs/examples/residency: one program, two tables filled by the same
loop, differing only in the annotation. Run twice against one WO_DATA
and orders replay while sessions do not
- the example checks its own claim (exits 1 if a durable:false table
survives, or a durable:true one fails to replay) rather than narrating
it in a print
- resident: keys is written out as a commented block with the loader's
exact refusal, so the frontier is visible in the example rather than
only in a story. It documents WHERE the refusal happens: woc compiles
it and emits a .wob; wovm exits 2, because the annotation is a
load-time property
- residency-accept gains two legs: the example runs and its restart
claim holds, and the refusal message the README quotes is checked so
doc and code cannot drift apart
- the gate writes the example's output to /tmp/residency.log,
banner-separated, for tail -F
- README commands verified verbatim; they needed mkdir -p because wovm
will not create WO_DATA

(cherry picked from commit c9c7e03e62c3918cb65ef7994d1e33a0c5337b71)
- loader's resident:keys refusal said "rows are still fully resident"
and "until tasks 5c/5d land". Both false since f606fc9. Corrected to
name the real blocker: UPDATE needs read-modify-append
- databasev2 00-story: the sequence graph drew 2->3->4, which reads as
3 needing 2 and 4 needing 3. Both backwards, and it still drew the
2->5->6 path the 2026-08-27 amendment retired. Redrawn stating only
real dependencies, with 4 and 3 shown as composing rather than
ordered, and the execution order that actually happened
- databasev2 03: the hazard and its Outstanding entry both claimed
nothing fails "because iteration 2's storage half is unimplemented".
Marked discharged, and recorded that the hazard named only half the
danger — the bitmap walk would have dropped keys rows outright
- databasev2 06: pending -> hold (largely superseded, revisit only on
a measurement); dated its 5c/5d references
- porch 01: rewritten to the settled shape. readiness ready, status
in-progress, phases B and C marked superseded with why
- porch 01 claimed time.after "is still a reserved builtin id". False —
builtin 90, implemented. That claim is what made the iteration look
cheaper than it is
- porch README gains honest ledger rows for both features (partial,
being rebuilt), not shipped
- skill-catalog README pointed at a story path that moved tracks;
linkcheck now 0 broken

(cherry picked from commit b3d8c403e1d19ac27ec966de85cb293e0765795c)
The branch was 17 ahead / 25 behind with 11 conflicting files, and drifting
further: db.c had been rewritten twice on master since (group commit, then
compaction). Resolved rather than rebased so both histories stay legible.
Conflicts, and how each was settled:
- db.c: BOTH semantics kept. Master's fatal path and compaction check now sit
behind the branch's `table_is_durable` predicate, in all three inline arms —
a volatile table reaches neither the barrier nor the compaction check
- db-bench sample: every mode from both sides (growth, growth-verify, randread,
replayseed, wmix) and ONE `boot` mode, which both sides had added
independently
- db-bench.py: all six legs kept. Both sides had also grown the same
WAL-size helper under different names; collapsed into one
- perf-targets: the branch's §5 (RAM ceiling) then master's §6/§7 — master's
numbering had already assumed a §5 it did not have
- story frontmatter: master's `status` (the landing truth) plus the branch's
`readiness` axis. 03 would have read `done` + `refine`, which is a
contradiction — it was brainstormed and landed on master, so `ready`
- board: both standup blocks newest-first; master's chain rows (a superset);
the branch's databasev2 1-2 rows with master's 3-4. Fixed a stray `|` in
master's row 3
- baseline: master's, then REGENERATED from a full campaign — 143 metrics,
132 checks, 0 failures with both sides' legs present
TWO HALF-EXPOSED FEATURES FIXED, because the merge rule is that master gets
no feature that is honoured in name only:
- `resident: keys` PARSED, set a .wob flag, and did nothing: rows stayed fully
resident. A developer could declare a 120 GB table keys-resident, watch it
compile, and be OOM-killed. The loader now REFUSES it with a message naming
what to write instead, until tasks 5c/5d land. The compiler still parses it
and its AST golden still passes, so the grammar work stays tested
- `durable: false` was honoured ONLY on the inline path. wo_db_exec_req had no
guard at all, so a volatile table written from an actor on a worker shard
would still be logged — precisely porch's session-table case, and precisely
what iteration 2 exists to provide. All three request-path arms now carry the
same predicate. Found by reading the merged code, not by a test: the obvious
probe runs main() on the primary and therefore only exercises the inline path
Verified on the merged tree: wovm-test 0, woc-test 0, oop-e2e 122/0,
residency-accept 8/0, db-bench 132/0, linkcheck clean.

databasev2 3, task 6. Documentation, plus three gate-tolerance
corrections that are justified rather than silent.
- 04-db-binding.md: the NORMATIVE rule — compaction may run only where
nothing is staged (a correctness requirement, not scheduling), recovery
is unchanged, and a failed compaction is a missed optimisation rather
than a durability event
- database/src/CODE-LOGIC.md: why one file and not snapshot-plus-tail
(Postgres CANNOT compact — page deltas; ours are full row images, so a
compacted log IS a store), why rename is the whole crash-safety story,
why the dump flushes but does NOT fsync when it does, why the
replacement is preallocated, and where the trigger is checked
- README: the checkpoint knobs, the extended walstats line, the boot mode
- story -> status: done, with criteria split met/outstanding
- board: standup entry in the six-question shape, both rows rewritten
THE OBLIGATION IS AT THE COMPACTOR, not only in a spec: compaction moves
every record, so it invalidates every WAL offset iteration 2's
`resident: keys` stores, and the loop that knows each record's new
position must rebuild that map. Nothing fails today because that storage
half is unimplemented — it would fail later, looking like corruption.
Board claim corrected before it shipped: I wrote that the concurrency
chain is "complete". It is not — chain 5 stays in-progress because
databasev2 4's part B was never done and its premise was invalidated by
part A. Every link has landed its PLANNED work; that is a different
statement.
Gate tolerances, each with the measurement that justifies it:
- ckpt.pause_us_max is no longer gated relatively. The raw pause scales
with the live set and this workload's live set is not fixed (wmix's
hist_dump inserts a row per latency bucket), so gating it gates the
box. Added ckpt.pause_us_per_mb — the engine's own rate, gated for
real, and the metric that would have caught the 8x dump regression —
with the absolute 50ms budget still guarding the raw pause
- ram.*.msgrate 15% -> 70%. PRE-EXISTING, and measured: 10.7M-17.9M
msgs/sec across ten full runs, several predating this work — a 1.67x
spread against a 15% gate
- durable.sN.*.p99us 100% -> 300%, with more evidence than the first
widening: mixread 1043/2318/4147us, mixwrite 1623/4446us on the same
build. Floors stay the real guard and are not slack
Battery: wovm-test 36 suites 0 fail, woc-test, oop-e2e 119/0,
db-bench 117 checks 0 failures, linkcheck clean.

databasev2 3, task 5.
Full campaign, same workload twice, differing only in whether
checkpointing may fire:
- WAL used 1962358 -> 907094 bytes (2.16x reclaimed)
- boot 114 -> 64 ms (1.78x), median of 3
- stop-the-world pause max 2651us against a STATED 50ms budget
The budget is asserted, not assumed: 50ms is a stall a serving process
can absorb without a client seeing a timeout, and the leg fails if it is
exceeded. The pause is O(live rows) — at ~181 MB/s a 1GB live set implies
~5.5s, which is the number an incremental design must be bought against.
The spec deliberately did not buy it in advance.
FOUND BY MEASURING: the dump was 8x slower than it needed to be. It
flushed through wo_wal_commit, which fdatasyncs, so it paid one barrier
per 256 records. Intermediate durability there is worthless — the temp is
not authoritative until the rename and is fsynced once immediately before
it. With a single final barrier:
- ~107KB live: 23948us -> 2903us
- ~500KB live: 36361us -> 7526us
- ~1.98MB live: 107649us -> 13212us
- marginal ~22 MB/s -> ~181 MB/s, sync-bound to bandwidth-bound
Correctness re-proven after that change: wovm-test 36 suites 0 fail,
test_wal 760 pass including the 40-round kill-during-compaction battery.
Two measurement defects of my own, fixed rather than reported:
- boot measured through the driver's run() helper reported 251ms both
with and without checkpointing — run() samples RSS on a 250ms poll, so
every timing floors at the quantum. Measured directly instead, median
of 3
- ckpt.reclaim_x was recorded as lower-is-better by the default detector,
which would have PASSED "reclaimed nothing" and FAILED an improvement:
the feature's central claim, gated backwards. Now higher-is-better,
gated at 15% while the wall-clock metrics stay wide — waiving them all
would have left the leg ungated, part A's task 4 mistake
- sample gains a `boot` mode that does nothing, so boot time is boot time
- walstats now reports compactions, pause max/total and compacted bytes
- baseline refreshed from the FULL campaign (N=20000, crash_reps=3), and
a fresh full run passes 116 checks 0 failures
- gate bites: reclaim_x doctored to 1.0 -> FAIL on exactly that metric
One flake seen and checked, not papered over: durable.sN.query.ops_sec
failed once at 53% below baseline. It is a read-only metric that touches
no WAL code, and a re-run passed 116/0 with the box at load 1.85.

databasev2 4 part A, task 6. Mostly documentation, plus one real fix the
full battery caught.
THE FIX. The drain held EVERY DB reply until the barrier — including
reads, which stage nothing and have no stake in durability. That parked
readers behind an fsync for no reason: durable.sN.mixread.p99 rose from
~1043us to 4057us. Only a statement that actually staged a record now has
its reply held. Caught by the gate, not by review.
THE TRADE, recorded rather than smoothed over. What remains is inherent: a
barrier blocks the owner shard LONGER (more records per fsync) though LESS
OFTEN, so anything queued behind one waits. Three full runs of the same
build gave durable.sN.mixread.p99 of 1043 / 2318 / 4147us and wmix.p99 of
8758 / 20000us — a 2-4x spread with the box near idle. So part A buys ~3x
write throughput at the cost of a longer, noisier tail on the owner shard,
and that is the strongest argument for part B (submit and keep serving).
- durable.sN.*.p99us tolerance widened to 100% WITH the reason in the
code: a 2-4x-variable tail gated at 50% gates the disk, not the engine.
The floor is the real guard and is not slack — mixread's (4172us) came
within 25us of tripping on the worst run. Baseline refreshed; a fresh
full run then passed 106 checks 0 failures
EXIT STATUS MOVED 3 -> 74 (sysexits EX_IOERR). 3 and 4 are already used by
SAMPLES for their own meanings — db-bench's own `verify` exits 3 on a
checksum mismatch, and it is the gate that exercises durability, so a
durability abort exiting 3 would have been indistinguishable from the
mismatch it should help diagnose. The low range belongs to programs.
Docs:
- story: progress, the payoff measured two ways, the cost side, criteria
split met/outstanding, and a "part B — its premise changed" section:
it was justified by "close the 66x gap", but that gap is two problems
and only the concurrent one was a batching problem
- board: standup entry in the six-question shape; both databasev2 4 rows
rewritten. They had said "close the 66x gap" — recorded as MIS-STATED
rather than quietly renumbered
- 00-wob-format.md and 04-db-binding.md: the normative failure contract
("a failed WAL commit traps WO_T_IO after un-applying the row") was
false; corrected, along with the tick-scoped group commit that never
happened
- database/src/CODE-LOGIC.md: where the barrier runs and why there, why
replies are held, why the inline path is asymmetric, the one failure
rule, and how to measure it
- db-bench README: the wmix mode, the env knobs, and the tmpfs warning
Battery: wovm-test 36 suites 0 fail, woc-test, oop-e2e 119/0,
db-bench 106/0, linkcheck clean.

databasev2 4 part A, task 4. Scope extended with developer approval: the
plan authorised touching the sample only for observability, but no
existing leg has enough concurrent durable writes to exercise group
commit at all, so the payoff was unevaluable either way.
The finding that forced it:
- `mix` writes on one op in ten with C=4 (all_mode calls mix_mode(n/10,
4); Mixer writes on i % 10 == 9), so the quick run performs 20 writes
total. Measured mean batch 1.01 over 3112 barriers, peak 3
- that is a property of the WORKLOAD, not the mechanism: peak 3 of a
possible 4 shows batches form whenever writes actually coincide
- `wmix N C` added: every op a durable write, C at once. Updates rather
than inserts, so it is comparable to mixwrite and the row count stays
flat. Histogram kind 2 — a replayed store still holds the seeding run's
kind-0/1 Hist rows and merging those would report someone else's
latencies
- WO_WAL_STATS=1 prints one line at exit: batches, records, peak_batch,
peak_staged. Opt-in, because it would otherwise pollute every durable
program's output. Counters live in wo_wal; no builtin, the numbers are
diagnostic and not part of the language
Measured, and it scales with concurrency exactly as designed:
- C = 4 / 16 / 64 -> mean batch 1.13 / 1.76 / 5.35, peak 3 / 10 / 39
- the gate's own legs: durable.s1 5412 records over 5412 barriers (mean
1.0, peak 1 — the inline path, one barrier per statement BY DESIGN),
durable.sN 7757 over 2296 (mean 3.38, peak 28) at 2x the throughput
- peak staged 1372 B settles the no-cap decision with a number: the batch
is tiny, so the upstream mailbox bound is sufficient
- mean_batch/peak_batch are higher-is-better (the default detector would
have called bigger batches worse)
- only the batch SHAPE metrics are waived to 100%; wmix throughput and
latency keep real tolerances (15% s1, 50% sN) — a blanket waiver would
have left the entire new leg ungated
- the live assertion `mean > 1.0` on the sN leg is what catches inertness
- gate bites: sN wmix ops_sec -60% -> FAIL on exactly that metric, 1 of 86
Verified: db-bench-quick 89 checks 0 failures; baseline refreshed (86
metrics).

Iteration 24 closes, absorbing 31 and 34. No code in this commit.
- stories 24, 31, 34 -> `status: done`, each with a landing banner. 24's
records the gate numbers and BOTH disclosed deviations: monitor takes
three arguments (the caller may be `main`, which has no mailbox) and a
v1 `call` reply is a typed scalar (which is what let the agreement be
checked at compile time, WO-E226). 31's notes it landed INSIDE 24 and
that a fifth mechanism it never anticipated came out of proving the
gate — the drain guarantee (40). 34's names the gap it did NOT close:
still no RNG, so CSRF/sessions stay blocked
- board: in-progress row cleared, marker doc deleted (convention), the
standup entry in the six-question shape, chain note — next link is
databasev2 4 (io_uring group-commit, chain 5)
- graph: PUBSUB2 (pub/sub + WebSockets, "rejected until here") -> done
- porch ledger: a WebSocket/pub-sub row added; the cancellation row now
says what it actually waits on rather than repeating "the arc"; the
README's "no WebSockets/SSE" limitation was stale — WebSockets are
supported, SSE and chunked encoding are not
- CODE-LOGIC: runtime/src gains the actor-lifecycle section (call, death,
the cap counter's sender/home-thread split, the monitor walk, the timer
list), the drain guarantee, and the digest section; docs/examples/chat
gains its own — actor topology, WHY two actors per connection, fd
ownership, and the shutdown choreography
Battery after the doc edits: wovm-test 36 suites 0 fail, woc-test exit 0,
oop-e2e 119/0, chat 11/0, web-app 46/0, linkcheck clean.

Gate defects, all measured:
- fd check was core-count dependent: `fds_before + 8` read LAZY per-shard
init as a leak. Shards init on first fiber, each taking one io_uring +
one eventfd, capped at nproc; on 20 cores the first wave legitimately
adds 18. Measured 26 -> 44 after 20 clients, still 44 after 40 more.
Replaced with the invariant the check is for: a second wave must not
raise the count. Core-count independent, and catches a slow leak that
any fixed slack would hide
- a failed leg ORPHANED its server: drain inherited $SRV from the soak
leg, so its python died on int("") and the soak server was never
killed — its listener then broke the next run's soak on the same port.
drain now starts its own server; cleanup kills every server a run
started, matched on the run's unique temp dir
- two legs the plan requires were missing: WO_SHARDS=1 (the single-shard
control) and WO_MAILBOX=8 (drop-slow-member backpressure). Both added,
both green. The mailbox leg shrinks the slow client's SO_RCVBUF so it
needs no sleeps
- chat adopted the porch naming (use porch/..., [deps] key) after the
rename landed on master
Decoupling the legs exposed a REAL drain bug, traced and documented in
docs/2026-08-27-chat-drain-finding.md, NOT fixed here:
- on a FRESH server the SIGTERM drain is flaky: 5 of 16 runs left a
client at EOF with no close frame and no diagnostic
- traced: main -> Registry -> Room -> Writer. Registry runs (diag
confirms), the Room NEVER processes its shutdown message, so the
Writer's close branch never runs. Clients that do get a frame are
saved by their own Reader seeing env.stopping()
- ruled out: the spin budget (a 1s wall-clock deadline still failed 2 of
12 — reverted, it fixed nothing and cost 1s per shutdown),
dummy_writer() spawning during shutdown, and write failure
- the fix is an engine guarantee — a send issued before the stop flag is
delivered — which belongs to the actor lifecycle, not a spin count

Closes the last gap in databasev2 1; gives databasev2 3 its "before".
- `boot` mode: does NOTHING. WO_DATA replay runs before main, so a mode
with no work measures replay plus a fixed startup
- `replayseed N M`: N inserts + M updates — same live rows, longer log
- `replay` leg: empty-store startup floor measured and SUBTRACTED, then
two shapes timed, median of 3 boots each
- premise check: updates must actually append WAL records, else the two
shapes are one measurement and the penalty means nothing
- WAL bytes = non-zero prefix, never file size (fallocate'd to 1 MiB)
- per-record cost stored in NANOseconds: as us it rounded 5.5 and 5.3 to
6 and 5, too coarse for the number a checkpoint exists to improve
- 148 checks, 0 failures; gate bites on a doctored ns_per_record
Measured — same 20 000 live rows, different history:
- 20 000 records: 980 035 B WAL, 110 ms replay, 5.5 us/record
- 40 000 records: 1 960 035 B WAL, 211 ms replay, 5.3 us/record
- 1.9x boot cost for an IDENTICAL dataset; per-record cost flat, so
replay is linear in records not rows
- extrapolated: 10M records ~55 s of boot, 100M ~9 min
- databasev2 3 correction: it planned to use "22's aged-store replay
numbers", which never existed — 22 proved restart correctness, never
timed it
- databasev2 3 hazard recorded: compaction rewrites the log and moves
every record, so it invalidates every `resident: keys` offset — an
arbitrary byte in a rewritten file, not stale-but-readable
- databasev2 1 -> status: done
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- `randread N R` in the sample: fill N rows, read R across the WHOLE range
- Weyl order `i*2654435761 mod n` — no RNG in the language, none needed;
both legs read the SAME key order so residency is the only variable
- `randread` driver leg: control (256 MiB, does not bind) vs over-cap
(6 MiB + swap), sizes kept modest — quick resolves it in ~5s
- gates the RATIO, not the absolutes: over-cap reads/sec belongs to the
box's swap device, the factor between two runs belongs to the engine
- reads must all resolve (hits == R) or the leg fails; a collapse measured
over unresolved reads is noise
- 133 checks, 0 failures; gate bites on a doctored collapse_x
Measured — this closes the gap the swap leg left:
- resident 1 851 166 reads/sec, p50 0us p99 1us
- over-cap 6 771 reads/sec, p50 128us p99 487us
- 273x throughput, ~480x p99, all 20 000 reads resolving in both
- so the two access patterns sit ~270x apart under identical pressure:
append-mostly insert ~1%, random read 273x
- departure is a STEP not a curve (1us -> 487us, nothing between), which
is why p99_departure_decile finds no knee — there is none
- caveat recorded, NOT inherited: this is demand-paged anonymous memory
through swap (4 KiB/fault, no readahead). `resident: keys` preads via
the page cache — should be better, but databasev2 2 task 7 must measure
its own read path. New criterion added there
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- `Wide` text-heavy reference shape beside Int-only `Item`
- `growth N int|text`: per-decile RSS read from own /proc/self/status
- `growth-verify`: survivor of a crash must be a contiguous intact prefix
- four footprint legs under a rootless cgroup v2 cap, swap on/off
- `ceiling` leg: die at the cap, then replay must come back intact
- footprint read as median-of-marginals; doublings a separate metric
- 121 checks, 0 failures; footprint gated ±10%, kill-timing ±100%
Measured, and it inverted two of the iteration's own predictions:
- footprint 96.5-100 B/row Int vs 320.6-324 B/row text = 3.3x, NOT the
"order of magnitude" three docs asserted
- table storage has NO checked ceiling: SIGKILL signal 9, not a catchable
WO_T_OOM. overcommit lets malloc succeed; kernel kills on page touch
- swap is NOT latency collapse: 900k rows 148s capped-with-swap vs 150s
uncapped. Append-mostly never re-touches cold pages
- ack-after-fsync survives an OOM kill: ~40k rows, no holes, no corruption
- iteration 2's budget dependency is REMOVED not satisfied — there is no
"swap onset" to derive a fraction from
- fix: subprocess returncode -9 was labelled a "checked refusal"; 137 is
the shell spelling of the same signal

- docs/stories/databasev2/, numbered from 1. Six PENDING database iterations
moved from the language track and renumbered, keeping the old id in
`was_language_iteration:` so a search for "iteration 32" still finds it:
32 -> 3 WAL checkpoint, 23 -> 4 io_uring commit, 33 -> 7 single-file store,
27 -> 8 query grammar, 20 -> 9 cross-program, 21 -> 10 keypair auth.
Done work (9, 9b, 22) stays as v1 history; language 18 left whole
- the problem, read off the engine not guessed: rows are malloc'd slabs with
addresses stable forever, NO eviction/spill/paging anywhere in database/src,
the WAL never checkpoints so boot replays all history, and durability is one
process-global WO_DATA so no table can say it matters more than another.
An allocation failure IS a clean catchable WO_T_OOM — but swap thrash
arrives first and carries no error signal at all, which is the real hazard
- four new iterations:
1 measure the ceiling FIRST (curve not cliff; the three exits; kill -9 at
exhaustion) — every later default should follow from a number
2 `@table(mode: ram | durable | cold)` — the grammar ask. Small surface
(Ast.table_cfg gains a key, the parser already rejects unknown args), big
semantics: `durable` defaults so nothing changes silently, and the
compiler refuses a durable row holding a `ref` into a ram table
5 bounded tables + refuse/evict/back-pressure, shedding BEFORE the OS acts
6 cold tiering — mostly forks, incl. whether the language surfaces the
fault cost and whether @unique on cold is refused outright. A paged
B-tree stays rejected: if tiering needs one, reject tiering
- 39 links repointed, link TEXT renumbered to track-local ids; arc gains one
pointer row replacing the six moved; board + board-views cover three tracks
- linkcheck 0 broken / 0 anchors; no code blocks in any story

- docs/stories/porch/ — a TRACK folder, not a status folder: status still

docs/stories/ can tell a porch 3 from a language 3
- 00-story.md carries the sequence, the dependency graph, and a table of
what the track explicitly does NOT own (binding -> 29, cache -> 18,
proxy -> 38, metrics -> 30, TLS/templates -> doctrine)
- eight iterations, each with phases, per-phase tasks, Given/When/Then
criteria, out-of-scope and the forks a spec must settle:
1 store-backed middleware (limiter + idempotency — needs nothing new,
first on purpose so the store pattern is proven cheaply)
2 randomness + cookies (phase A is language-track: a CSPRNG builtin;
`Resp.headers` being a map cannot emit two Set-Cookie lines)
3 sessions 4 CSRF 5 routing/response ergonomics (independent)
6 streaming core (the seam 7 and 8 wait on; chunked-request refusal
must survive) 7 SSE + compression 8 static + lifecycle hooks
- language iteration 39 -> status: hold, retitled superseded, with a row
mapping each of its goals to the porch iteration that took it. Kept, not
deleted: the Fiber study cites it and its randomness argument is what
this track is built on
- board gains a porch section; board-views gains porch and both-track
Dataview queries; porch README and the Fiber study §7 point at the track
- no code blocks in any story (plans carry concept and actions in words);

- docs/examples/writeonce-serve -> docs/examples/porch (git mv, history kept);
`[deps]` key and import are now `porch` / `porch/http` / `porch/router`
- name history preserved on the library README, not rewritten into dated
records: writeonce-framework -> writeonce-serve (08-25) -> porch (08-26).
Stories, specs, plans and the audit reports keep the older name by the
repo's own convention; only live docs and every path link were rewritten
- left alone deliberately: `internal/serve.wo`, `pub fn serve`, `serve_conn`,
`app.serve(...)` — those are functions, not the module name
- web-app/wo.toml comment corrected: it claimed hyphens are not identifier
characters and named a key this file never used. lexer.ml's `is_ident_cont`
DOES accept `-` (an internal dash is part of the identifier, which is why
binary minus needs spaces), so a hyphenated key would be legal too
- site now teaches the name: package card, the two-deps chapter and the
handlers-are-classes chapter say `porch`; site-accept asserted the old
/packages/serve route and caught the rename, as a gate should
- gates: web-app 46/0, site 21/0, deps-accept 8/0, oop-e2e 116/0,

- README: shipped concurrency/HTTP/WebSockets sat in the roadmap as "not yet
available"; "no package manager" contradicted [deps]; the deps example
would not have compiled (the key IS the module name)
- runtime/README: leads with wovm, wo-rt.c demoted to a historical section;
dropped 2 nonexistent recipes, crates/rt, @gc refcounting, 13 suites -> 18
- employee + log-watcher READMEs claimed "does not compile"; both are gates
- error catalog: +10 emitted codes incl WO-E250, the only diagnostic the
shipped query surface raises; recorded why the sweep rotted
- language-surface: group-by parses, then the typechecker refuses it
- 00-code-review + 00-link-audit re-run; history kept, not rewritten
- 48 dead Rust-era exploration links de-linked rather than re-pointed (their
prose names the retired plan by number); successor map -> discarded.md
- 08-project-structure: compiler/plan/ never existed; corpus has 9 dirs, 5 empty
- releasing.md: dropped a --draft step the workflow never had
- new docs/00-doc-audit.md: findings + disposition, incl one row where the
audit was wrong and the doc it accused was right
- status folders removed: 34 stories flat, status only in frontmatter; 252
links recomputed from resolved paths; board/board-views/structure retaught
- story 24 -> in-progress, since frontmatter is now the only truth
- new iteration 38: fs mutation verbs + net.connect, the two capability
families no iteration owned
- new iteration 39: gofiber/fiber v3.5.0 parity study. The ledger called
CSRF/sessions unblocked by iteration 34's HMAC, but the runtime has no
source of randomness at all
- linkcheck skips .dev/.superpowers: 0 broken paths, 0 bad anchors

- "View source" and the nav GitHub link pointed at the user profile
(github.com/shoneyj); both now point at github.com/shoneyJ/writeonce
- README: what actually has to reach the host — the self-contained
binary plus dist/ (served by /dl) and data/ (WO_DATA) — and the four
environment variables, with SITE_HOST left UNSET behind a proxy so
the process binds loopback
- says plainly that dist/ must hold the PUBLISHED release assets: the
build is not byte-reproducible, so a local tarball would not match
the published .sha256 and the mirror would disagree with GitHub
Prepared and verified locally: docs/examples/site/dist/ holds the real
v0.1.0 assets (digest matches the release) and target/site serves them
byte-identically. Both directories are gitignored.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The published v0.1.0 binaries need less than the page claimed:
woc imports up to GLIBC_2.35, wovm up to GLIBC_2.34. The page said
2.38, which was measured on a dev workstation (glibc 2.39) before CI
existed — and understating support turns working platforms away.
- supported systems: glibc 2.35+, covering Ubuntu 22.04+, Debian 12+,
Fedora 36+
- RHEL 9 (2.34) runs wovm but not woc: build elsewhere, copy the
self-contained binary
- say plainly that the floor is set by the machine that BUILT the
release, which is why CI pins ubuntu-22.04
- site-accept follows the new string
This is the pinned-runner decision paying off: 2.38 -> 2.35.

- rename the two libraries: writeonce-framework -> writeonce-serve
(`use serve`), wo-html -> writeonce-view (`use view`). Names say the
ROLE now; every sample, script, gate and live doc follows
- stories/specs/plans keep the old names: they are dated records, and
both library READMEs carry a "renamed 2026-08-25" note
- serve/http/files.wo: StaticFiles { dir, max_bytes } — traversal
refused not normalised, extension content types, attachment
disposition for archives. Lifted out of the shop, which had said in
a comment that it belonged in the framework
- shop drops its private copy and mounts the framework's
- site: /dl/*path over $WO_DIST (default ./dist), 16 MiB ceiling
- /install gains supported systems — Linux x86-64, glibc >= 2.38,
not musl — read off `file` and the binaries' GLIBC_ symbol
versions, not off a wish list; plus GitHub release as primary,
/dl as mirror, and the sha256 verify step
- site-accept: 17 -> 21 checks (supported systems, gzip download with
a binary-safe probe, checksum, /dl traversal 404)
Verified on 192.168.0.165: the real 960,820-byte tarball downloads
as application/gzip and its sha256 matches the published digest.
Gates: oop-accept MET, site 21/0, web-app 46/0, fibers 10/0,
db-actor 8/0; shop rebuilt and its /assets served by the framework.

- layout/logo.wo: the mark as inline SVG — dark tile, two-stroke "W"
(white then accent blue). One source: nav brand + /favicon.svg
- favicon/controller.wo: GET /favicon.svg, image/svg+xml, day cache
- install/: GET /install — toolchain tarball, PATH, verify, first
project, build/run, adding a dep. Copy from the real install README
- packages/: GET /packages + /packages/:name — catalogue with the
[deps] line, what each library gives you, and a usage snippet.
Index cards are child components (multi Component)
- wo-html: page_head(title, head, body) and a `head` slot on Layout —
a favicon link or meta tag had nowhere else to go; page() passes ""
- header: Install/Tutorial/Packages/GitHub, brand shows the mark
- main.wo: SITE_HOST picks the interface (loopback default), bound
address printed at startup
- site-accept: 11 -> 17 checks (install, packages x2, 404, favicon,
inline logo)
Verified on 192.168.0.165:8080 — every route, favicon bytes, and the
mark rasterised at 256px and 32px.
Gates: oop-accept MET, site 17/0, web-app 46/0, fibers 10/0,

- lexer: backtick raw text literal — content verbatim, no escape
processing, common source margin removed at lex time; `${ }` raw and
`{{ }}` auto-escaping holes
- `{{ e }}` desugars to `esc(${e})` in parser.ml — a Call on the `esc`
in scope, so types/owner/emit/.wob/VM are untouched
- WO-E004 unterminated raw literal; WO-E005 newline inside "..." —
closes a hole where a missing quote silently ate the rest of the file
- wo-html: `Component` interface, `render_all`, `Layout`, README
- framework: `ok_html` joins ok_text/ok_json in http/types.wo
- site + shop restructured to one-feature-one-module MVC (view +
controller per directory, model at the root, bootstrap-only main)
- removed the filler `pad: Int` convention — verified unnecessary for
plain classes, interface dispatch, containers and actors
- corrected recorded claims: gap #1 blocks neither the build nor the
layout; a class crosses module lines, only a free fn is scoped
- docs/guides/language-surface.md — the full grammar inventory
- story 37 landed and moved to done/

- render() bodies: one HTML line per 'h = h ..' statement, single-
quoted attributes, ${} holes, esc() on data — el() chains gone
- discovered + recorded gap #3: no multi-line expressions or literals
(leading/trailing .. and paren grouping all reject at NEWLINE) —
exactly the tax story 37's raw literal deletes
- 37-target comment blocks dropped (bodies now self-explanatory; the
README states the delta); rebuilt + full buy-flow re-smoked (178.0
total, stock 12->10, 409, traversal 404)

- separate view.html files dropped; every render() now carries its
'-- 37 target:' literal above the hand-lowered body — the pair is
the DX referendum in one file
- story 37 re-pointed: raw multi-line literal + {{ }} auto-escaped
typed holes + {!! !!} raw slots; structural control stays if/for;
w:if/w:for and .html files demoted to later; forks revised
- rebuild verified on untouched toolchain
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- view.html per feature + layout app/header/footer.html: the markup-
first form woc will compile ({{}} auto-escaped, w:if/w:for,
{!! !!} slots, w:component sections); inert today, verified not to
disturb the build
- README: pair is the DX referendum — .html is the target feel,
view.wo is today's cost; doctrine line reworded (templates compile
or don't exist)

- docs/examples/chat: registry (call consumer) / room / reader+writer
actor pair per connection over ws_accept + wsframe; presence,
broadcast, cross-room isolation, mailbox-full = drop-from-room;
reader tail sends hardened (a full writer no longer orphans the fd)
- RUNTIME SEMANTICS CHANGE (the drain): SIGTERM no longer kills parked
fibers from outside — the plane WAKES them and each wait RESOLVES
(deadline'd waits answer their timeout result, sleeps return early,
plain waits answer WO_SYS_STOPPED and unwind THAT fiber alone; main's
STOPPED still ends the program). Workers keep adopting their inboxes
after stop until eng_shutdown. This is what lets a program drain:
chat's close frames now reach clients (byte-verified 0x88), then
main returns and the reap runs
- also: SIGPIPE ignored process-wide (EPIPE trap instead of death);
two-phase engine teardown (real drops while arenas+routing live,
settle passes for routed frees) — fixes the registry-map leak and
the drain UAF ASan found
- gate scripts/chat-accept.sh + just chat: handshake independently
verified, functional matrix on BOTH backends, 1k-hot-room soak
(1000/1000 in ~35ms), drain close-frames, SIGTERM exit 0, ASan leg
clean. OPEN: soak-fds check (18 fds settle slower than the window)
+ full battery after the semantics change — NOT yet run
- committed for manual testing at the user's request
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- parse.wo: ANY Transfer-Encoding header is 400-and-close (RFC 9112
§6.1) — silently treating chunked as body-less was the smuggling
door the dup-CL fix left open
- net.listen/listen_unix backlog 64 -> 1024: the soak's connect bursts
overflowed the kernel accept queue and BLACK-HOLED clients (three-way
handshake done, server never sees the conn — 35-70 stuck per run,
fully reproduced then gone at 1024; kernel clamps via somaxconn)
- web-app gate grows to 46 checks: TE-reject; the 1k soak — 500 real
conns all served + 500 idle conns all evicted, server fds home
(45 -> 45), RSS 24MB, healthy after
- battery green (site restart + fibers-TSan legs flaked under parallel
battery load, both clean serially — the standing flake pair)
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- runtime ids 91-95: net.read_dl/accept_dl/write_dl (per-call deadline,
nil/false = the EXPECTED timeout; ms<=0 = old behavior bit for bit),
net.listen_unix (unlink-before-bind, O_NONBLOCK on the listener —
probe-found: accept4's flag covers accepted sockets only), net.peer
- plane: one-op-per-park stays law — deadlines ride one per-shard
TIMEOUT tick (sentinel user_data) + post-CQE expiry sweep +
POLL_REMOVE tombstone; epoll's deadline scan grew the fd-park case;
fibers POOL instead of freeing mid-run (stale-CQE UAF); plain parks
zero park_deadline (no stale sleep deadlines)
- probe: all five seams verified on BOTH WO_IO backends (timeout
timing exact, peer round-trip, unix rebind)
- framework: parse_request grows first_ms/read_ms; serve_conn — the
keep-alive loop with deadlines where parked idle conns are LEGAL
(close-when-idle RETIRED); App.handle_conn exposes it; plain serve()
unchanged for simple apps
- web-app: app-owned accept_dl loop + ConnWorker actor per connection
(each builds its own App; cross-shard placement rides the DB actor);
WA_IDLE_MS knob; gate grows to 41 checks — two slow requests served
in PARALLEL, stalled client evicted at the idle deadline, slow-loris
torn at the read deadline (400)
- docs: story 35 -> done with banner; SQE/CQE design spec LANDED (was
the review doc); ledger rows (timeouts/unix/keep-alive/peer), graph
(NETSEAM cleared, KEEPAL done), builtin-surface rows, runtime
CODE-LOGIC section, board entry
- battery 13/13 fresh-built
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- docs/examples/wo-html: library dep — esc(), element builders,
Tailwind-style utility sheet as one static string, page() shell;
self-contained responses, no CDN/JS/build step
- docs/examples/site: the language tutorial served by the language —
9 seeded chapters in a @table (hello/values+bitwise/containers/
classes/optionals+traps/tables/actors/deps/serving), server-rendered
via wo-html, seed-if-empty so WAL restarts keep admin edits
- routes: / index, /ch/:slug (styled 404), /health, POST /admin/ch/
:slug (bearer handler-side — mechanism framework's, policy app's;
form-encoded title/body update by assignment, 302 back)
- chapter code samples use the lexer's \$ escape to show ${...}
literally; .. never straddles newlines (accumulator style)
- gate: scripts/site-accept.sh + just site — TWO file:// dep remotes,
11 checks incl. authed-edit-survives-restart; /health polling, no
boot-race sleep
- README: run + nginx sketch for writeonce.de; CODE-LOGIC beside code
- full battery 13/13 (site gate included)

- Req grows internal conn field (net.Conn, filled by parse) — handlers
touch it only through ws_accept
- ws_upgrade_valid: RFC 6455 §4.2.1 (GET, Upgrade token, Connection
token list, 24-char key, version 13); ws_accept_key pure
(base64(sha1(key+GUID)) — the runtime vector already pins the RFC
worked example); ws_accept writes the 101 and returns the fd;
hijacked() = the status-101 sentinel
- serve.wo: 101 skips serialize AND close — the loop forgets the fd
and returns to accept; plain HTTP byte-identical (web-app 26/26)
- codec + end-to-end proof land with the chat sample's gate; battery
12/12 (fibers TSan leg flaked empty under load, 10/10 on rerun;
web-app restart leg has a pre-existing 0.5s boot race, noted)

- story 34: premise fixed — iteration 36 landed bitwise/hex, digests
and HMAC now expressible in pure .wo; C-builtin vs pure-.wo is the
story's brainstorm call, not an impossibility
- dependency graph: crypto gate names story 34; net-seam gate names
story 35; radix gate corrected — 22 benched the DB, router scan
still unmeasured, perf-targets entry first
- framework README ledger: timeouts/unix/peer rows point at story 35;
ETag row at story 34; path-matching row repointed off iteration 22

- brings time.ticks builtin (id 84), bench sample + campaign driver
(scripts/db-bench.py), just db-bench/db-bench-quick recipes, first
baseline recorded, story 22 to done/, postgres study cards
- conflicts resolved: board in-progress table (iteration 36 +
framework rows kept, db-bench row now "22 landed"; dangling order
anchor repointed); story 36 moved back to in-progress/ (dir-rename
inference dragged it to done/ — 36 still awaits the manual pass)

- framework README: three rows still said "until fibers/shards" /
"fibers (11)" — now "arc landed 2026-08-21, parked until own slice";
ledger date 2026-08-22
- dependency graph: crypto-fork gate note updated — bitwise + hex
landed with iteration 36, digests expressible in pure .wo; story
34's brainstorm still owns the pure-.wo vs C-builtin call

- engine: wo_idx_probe answers single-column equality from the index
hash buckets (idx_hash_key1 reproduces idx_hash bit for bit; verify
compares exactly as the slab walk did, so results identical);
composite indexes keep the walk; both executors wired (local + DB
actor RPC)
- compiler: probe_key_of_where lowers "var.col == key" on an indexed
column to DB_PROBE; all where guards still run (guard stays the
final arbiter); keys = ident/int-literal only; Float/Bytes excluded
(engine raw-eq narrower than VM float-eq)
- measured: reads 1.3k -> 1.3M ops/s, p50 600us -> 1us (~x850);
query x830; mixread 1.3k -> 89k s1, 21 -> ~1.9k sN
- gate policy moved into the driver (tolerance_for: refresh-proof);
latency floors max(4x,100us); quick mode skips poll-bound mix
floors; both tolerance classes proven to bite
- proof: test_table wo_idx_probe suite (RED first), corpus
query-index-probe 105/0, full battery green, TSan clean, two
campaigns pass the refreshed baseline
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- bench/baseline.json: 74 metrics from the first full campaign;
tolerances tuned by a two-run repeatability check (mix* 50%,
read/query 35%, rest 15% — rationale in _config)
- gate bites: --check mode; doctored copy fails, both real runs 74/0
- headline: durable seed 4.5k/s vs ram 297k/s (23's case); reads
O(table) at ~1.5k/s; mixread 1280 vs 21 ops/s single-vs-multi
(the arc's price); msgrate 13.4M vs 2.45M (mutex-inbox number)
- arc delta recorded in story 8; findings in sample README
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- 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)
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- seed/read/query/write/wal/verify/verify-acked + all (one-process
campaign: RAM store dies with the process)
- per-op time.ticks, 1us-bucket histogram percentiles (reservoir
deviation: no element-write/sort in language; better tail anyway)
- 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
all slabs; the number 22 exists to surface

- 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
x3, uring/epoll forced, single byte-exact, WAL replay pair);
ASan+TSan 6/6; full battery green

- 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
