- docs/plan/oop-vm/04-db-binding.md, WAL section, "Where the log lives":
WO_DATA is always a path; directory form (existing dir or trailing `/`
→ `<dir>/shard-0.wal`, pre-7 bytes incl. the `//`), file form (the path
IS the log, created only under an existing parent), the two refusal
lines verbatim, too-long refused not truncated, one file at any core
count, compaction/migration temps + parent fsync derived from the log
path never from WO_DATA, the two pinning tests named.
- database/src/CODE-LOGIC.md, `wal.c — durability`: the resolver's three
codes and main.c's wording, why no mkdir -p, trailing slash on a missing
dir kept as the pre-7 `cannot open` on purpose, `parent_dir_of` shared
by the boot check and the post-rename fsync.
- Both paragraphs sit in regions untouched by the uncommitted 6a/12 doc
work in the same files; no other docs touched (story/board are pm's).

(cherry picked from commit f1985bae5d110ed773159393bd82c32b73bfb672)
- emit.ml: a `try … catch (e) nil` is `?T` (ty_of_expr) and the nil arm takes that destination, so a `?Int` nil is WO_NIL_SCALAR and an Int body's legitimate 0 no longer reads as nil (it used to fall back to the zero word via the body type / enclosing return type)
- owner.ml: `transfer` on a projection (`d.tags`, `x[i]`) of an owned value reports WO-E305 instead of returning false silently — the silent path compiled `Out { tags: d.tags }` to an alias that both records dropped (the "json.decode as T corruption": not json's, a double free language 44's poison now aborts on); heap scalars exempt (store sites copy)
- error catalog: WO-E305 row; owner.ml module doc updated
- corpus: run/try-nil-int-zero, compile-fail/no-partial-move, run/decode-record-crosses-return (Text copied, record moved whole — the archived `.. ""` workaround is unnecessary)
- verified: oop-e2e 126/0, tests/regress/lang-41 compile, --emit sweep over the non-porch examples, web-app gate 56/0 (porch in project mode) — no legitimate program trips WO-E305

(cherry picked from commit 2d54710e693fafee4b8d6561cc9cba7b95415d89)
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 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.

Task 3 of docs/superpowers/plans/2026-08-26-table-residency.md.
- NO LAYOUT CHANGE. The plan said to add descriptor fields; the descriptor
already had a `flags` u32 with only bit0 used, so both properties ride
spare bits (WO_CLASSF_VOLATILE 0x02, WO_CLASSF_RESIDENT_KEYS 0x04). A v7
class record is byte-identical in shape to a v6 one, which is a much
smaller and safer change than the plan assumed
- both spelled as the NON-default, so a zero flags word means exactly what
every pre-v7 image meant: durable, every row resident. A non-@table class
has both clear by construction
- the loader refuses the meaningless pair (bit1+bit2) independently of woc,
on the standing principle that what the loader accepts the interpreter
trusts. Verified by FORGING the flags word in an otherwise valid image,
since woc will not emit one: flags=6 gives "durable:false with
resident:keys", flags=8 still gives "unknown flags"
- WOB_VERSION 6 -> 7. Kept because an OLDER runtime reading a v7 image would
otherwise treat a volatile table as durable and quietly disagree with its
own source. loader.c's check is exact-match, so a v6 image is refused
rather than read with the bits clear — verified by patching a v7 header
back down to 6
GAP FOUND AND CLOSED: woc ACCEPTED `durable: false, resident: keys`. Task 1's
steps covered duplicates and bad values but never the combination, and the
plan had only put that refusal in the loader. The spec wants both, so the
compiler now refuses it too (WO-E102, checked after the argument list is
complete since it is a property of the pair). A compile error is the one a
developer can act on.
VERSION DRIFT: the constant lives in FOUR places, not one. wob.h,
emit.ml:157, disasm.ml:186, and compiler/test/runner.ml:2405 — the last is a
deliberately independent reimplementation of the loader battery, and it
caught the drift as 14 failures rather than silently passing. Its flags mask
and the combination refusal are now in sync too, which is the point of it
being independent rather than shared.
Gates: woc-test 557/0, 18 runtime suites 0 fail, 18 ISO-flavour suites 0
fail, cli_smoke OK, oop-e2e 118/0, employee 8/0, db-actor 8/0, site 21/0.
Zero goldens moved (git diff over golden/ empty).

Task 2 of docs/superpowers/plans/2026-08-26-table-residency.md.
- the check lives in `check_field_types`, which already runs over the raw AST
(so the diagnostic lands at the field's own position, once per declaration)
in Pass 2 with `syms` fully built
- only the durable -> volatile direction is refused. volatile -> durable is
legal: the referencing row is the one that disappears, so nothing is left
holding a stale id
- the message names both classes and both escapes, because "this is wrong" is
less useful than "make Session durable, or declare Order volatile too"
- sees through a `?` wrapper, so `?ref S` is caught too
- code picked as 24 by sweeping `<stage>_prefix ^ "NN"` — 01-23, 25, 26 and
50 were taken, so 24 was a genuine hole. Grepping the literal WO-E224
would have found nothing, which is how ten codes once went missing
- catalogued in the same commit, and the completeness sweep re-run: 53
emitted, 54 catalogued (the extra is retired WO-W201), none missing
PLAN CORRECTION: the plan's second step said to apply the same check to
`backlink` fields. Dropped — a backlink is "NOT a stored column" (ast.ml:72),
so after a restart it resolves to an EMPTY COLLECTION, which is a legal state
indistinguishable from "nothing references me". There is no id to dangle.
Implementing it would have refused correct programs; a spurious diagnostic is
worse than a missing one. A run fixture now pins that the backlink shape stays
legal, so the check cannot silently grow over-broad later.
Gates: woc-test 557/0, oop-e2e 118/0 (was 116 — one compile-fail and one run
fixture added), employee 8/0, db-actor 8/0; employee, db-bench, db-actor,
porch, log-watcher and gc-cycle all still typecheck.

Task 1 of docs/superpowers/plans/2026-08-26-table-residency.md.
- ast.ml: `table_cfg` gains `durable : bool` (default true) and
`resident : residency` (ResAll | ResKeys, default ResAll) — both defaulting
to the pre-existing behaviour, which is what lets every @table written
before this compile byte-identically
- parser.ml: `durable:` takes the existing KwTrue/KwFalse tokens; `resident:`
takes the bare identifiers `all`/`keys`. Given-twice tracked by local seen
flags rather than option fields, so "absent" and "explicitly the default"
stay distinguishable without the AST carrying an option nobody reads
- five new WO-E102 causes, all catalogued in the same commit: durable twice,
resident twice, an unknown resident value, `resident: index` (the
pre-review spelling, with a message naming its replacement), and a retired
design word (mode/store/ram/cold/tiered/paged/mmap/buffer) which gets a
message stating the two real keys instead of a generic "unknown argument"
- dump.ml prints each property ONLY when it differs from its default.
Printing unconditionally would have moved every pre-existing golden, which
this iteration is not allowed to do
- new golden compiler/test/golden/ast/table-residency.wo covers all four
shapes, including a table declaring `resident: all` explicitly and
correctly dumping nothing for it
- verified, not assumed: `git diff --stat` over compiler/test/golden/ is
EMPTY after a WOC_BLESS run, so all 30 pre-existing goldens are untouched.
woc-test 557/0 (was 556), oop-e2e 116/0, employee 8/0; employee, db-bench,

- 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

- 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,

- 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

- docs/guides/language-surface.md — the full grammar inventory

observer's notice drops with a stderr line (no fiber to trap)
- time.after(ms, addr, msg): per-shard timer list riding the deadline
machinery (uring tick min + epoll timeout both include timers;
fired from the same sweep); ms <= 0 delivers now; NO cancel — the

- runtime_notify: one runtime-sourced delivery path (notices, timers) —
reserve-or-drop, cross-shard via kind-0 envelopes

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

WO_PARK_INBOX (the DB-RPC protocol) and the resume consumes a SCALAR
reply; FIBER_DONE ships the receive's return value home (same-shard
unpark or kind-6 envelope); kind-5 carries cross-shard calls

dead, error-unparks the in-flight caller AND every queued caller,
drops queued payloads + state, releases cap slots; send-to-dead
drops silently, call-to-dead traps — a call never hangs. Fixes the
pre-existing leak/dangle in TRAPF's fiber-death path (cur_msg leaked,
a->active dangled, the mailbox rotted)
- compiler: reply typing through actor-M erasure — every receive(M)
program-wide must agree on one return type and it must be a copyable
scalar (v1); WO-E226 names disagreeing classes / void receives /
non-scalar replies; call's message moves exactly like send's (owner)

- 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.

Closes json's two documented fidelity limits (iteration 5 strictness):
- field_class gains WOB_FIELD_BOOL (a plain `Bool` field) and
WOB_FIELD_NIL_BOOL (a `?Bool`: WO_NIL_SCALAR nil + bool encoding) — the
kind byte alone cannot tell a Bool slot from an Int slot, so the metadata
carries it. Emitter writes them (field_class_meta); loader whitelists
them; json.c encodes `true`/`false` (and `null` for a ?Bool nil), decode's
null/omitted-key pre-write covers NIL_BOOL.
- A JSON number with a fraction or exponent is MALFORMED for an Int field:
the checked decode (`json.decode(t) as T`) yields nil for the whole
document instead of silently truncating 3.7 to 3 — the language has no
float, and corrupting data quietly was the one thing a "checked decode"
must never do. Floats stay representable through a raw `json.Value` field.
- corpus: run/json-bool-fidelity pins the round-trip (true/false both ways,
?Bool null both ways, fraction AND exponent rejected).
- Board's two known-gap entries struck; format doc's field_class marker list
extended.
Verified: oop-e2e 87/0; runtime test + test-iso OK; woc-test 540/0;
log-watcher 7/0; employee 8/0.

The verdict table's reject half is enforced: a Haxe habit fails loudly at
its own position with the doctrine reason, instead of a generic syntax
error — or, worst, compiling clean: `return super.f()` used to exit 0 (the
unresolved ident placeholder swallowed it).
- parser.ml: doctrine_reject_reason maps each rejected word to its spec
reason (inheritance quartet -> principle 4; cast; Dynamic/untyped ->
principle 13; macro; extern -> principle 10; operator). Fired at three
chokepoints: `class B extends A` (with skip-to-brace recovery so the body
still parses), an expression head (`super`, `cast 3`, `untyped x`), and a
top-level declaration head (`macro fn`, `extern fn`).
- types.ml: `Dynamic`/`untyped` as a TYPE name keep their WO-E225 site but
carry the doctrine message.
- corpus: compile-fail/{reject-inheritance,reject-cast,reject-dynamic}.
- catalog WO-E105 row; plan 8 Task 8 reject half ticked (#if still open);
board updated.
Verified: woc-test 540/0 + test_diag 14/0; oop-e2e 86/0; log-watcher 7/0;
employee 8/0; legit identifiers (`extended`) untouched.

The hybrid-boundary inversion is closed: a statically provable interface
violation now fails at COMPILE time instead of reaching wovm as an ICALL
that traps WO_T_BOUNDS at runtime.
- types.ml class_satisfies: the same rule emit.ml's `satisfies` builds
vtable rows from (instance method with matching name + parameter count
for every interface method; `static fn` never satisfies) — one rule, two
consumers, so the check and the vtable can never disagree.
- check_iface_boundary fires wherever a confidently class-typed value flows
into an interface-typed slot: call arguments against the callee's declared
parameters (free fns, methods off confident receivers, interface-method
sigs, statics — resolved exactly as confident_typ resolves returns),
annotated `let`s, and `return`s. Silent when underivable.
- The same per-argument pass extends the ?T boundary to CALL ARGUMENTS
(the previous slice covered stores/returns/operands): nil into a
non-nullable parameter is WO-E212, an unnarrowed ?T argument is WO-E211.
- tests/corpus/trap/unsatisfied-interface -> compile-fail/ with
fixture.code WO-E205, per the fixture's own standing instruction; its
header comment rewritten to the wired reality.
- The new arg checks caught a real mistyped signature in the sample:
log-watcher's rpc_error/rpc_result/call_tool declared `id: json.Value`
while every caller legitimately passes nil (JSON-RPC id-absent) — now
`?json.Value`; dispatch/call_tool/cron-row sites moved to the
bind-then-narrow idiom (including an `or`-guard narrowing:
`if spath == nil or spat == nil { return }`).
- Catalog: E205 gains its main-table row; the "owed gap" section is
rewritten as closed. Board known-gap struck through.
Verified: woc-test 540/0 + test_diag 14/0; oop-e2e 83/0 (fixture now
compile-fail, satisfying-class negative probe compiles clean); oop-accept
ALL MET; log-watcher 7/0; employee 8/0; gc-cycle clean.

The type system now keeps its nullability promise: a `?T` value cannot be
used, stored, or dereferenced as a plain `T` without narrowing. The canonical
evidence probe (return b.v where v: ?Int, fn -> Int) that compiled clean for
months now fails with WO-E211.
- WO-E211 (un-narrowed use): arithmetic and </<=/>/>= operands, and/or
operands (?Bool), interpolation segments, for-iterables, and returns whose
declared type is not nullable.
- WO-E212 (boundary): nil or ?T stored into a non-nullable slot — annotated
let, assignment to a confidently-typed local (cenv, never the placeholder
env — a placeholder target must stay silent) or a resolvable class field.
- WO-E213 (deref): field/index access through a possibly-nil base.
- Narrowing (locals only — a field place can be re-assigned between check
and use, so chains bind to a local first): `if x != nil { }` narrows the
branch; a DIVERGING then-branch (`if x == nil { return }`) narrows after
the if; `x != nil and x.n > 3` narrows and/or right operands
(short-circuit); `while x != nil` narrows the body. The narrow is
un-applied when an else-less then-env leaks out un-diverged (the existing
env-leak convention must not leak the narrow).
- No false positives by construction: env/cenv types are declared or
confidently inferred; the placeholder fallbacks are plain scalars, never
?T. The whole golden suite passed untouched (540/0).
- Samples updated to the bind-then-narrow idiom (log-watcher config decode +
supervisor lock/next_fire, gc-cycle ring print) — 22 genuine unnarrowed-nil
sites; employee needed zero changes. All acceptances green.
- Corpus: compile-fail/{nullable-unnarrowed-use,nullable-nil-into-plain,
nullable-deref-unchecked} + run/nullable-narrowing (all four forms) — 83/0.
- Catalog: E211/E212/E213 move from "Reserved, not yet emitted" to the main
table; nullable-types-implementation.md status flipped to ENFORCED
(historical record kept); plan 8 Task 6 ticked (boxed scalar cells
superseded by WO_NIL_SCALAR); board updated.
Verified: woc-test 540/0 + test_diag 14/0; oop-e2e 83/0; oop-accept ALL MET;

The spec's §8 migration table, applied:
- 00-principles.md P3: "@gc is a per-class opt-in, reference-counted" ->
GC-ness is inferred; incremental per-shard mark-sweep in budgeted slices;
still no global pause by construction.
- OOP spec: decision-table GC row -> inferred (hybrid rule named); §3 rule 5
-> traced classes alias freely, which classes is inferred; §4 memory model
-> the RC + Bacon-Rajan paragraph replaced by tracing (snapshot roots,
Yuasa barrier, born-black, budgeted slices); header rc comment -> union'd
sweep link; mixing rule restated for tracing.
- 00-wob-format.md: header says version 4; opcodes 27-28 -> reserved (loader
rejects); the owned-temporary rule's @gc exclusion restated for tracing.
- 08-builtin-surface.md: the push RC_INC special case and the set(m,k,v)
retention gap DELETED — neither exists without RC; the corpus cycle is
collected by tracing.
- story 07b: status -> LANDED 2026-08-18 (with the historical note kept);
board: 7b row ✅ (supersedes iteration 2's RC memory model), pending row
removed.
- gc-cycle README: Phase 3 flipped to landed (the ring runs, is reclaimed,
ASan-clean; the ?Node RC_DEC-on-nil trap no longer exists); the barrier
prose corrected to the as-built design (snapshot-at-beginning + deletion
barrier + born-black, not per-slice root re-reads).
- plan 2026-08-18: all checkboxes ticked + a completion banner recording the
four deviations from the plan as written.
(Error catalog was already amended with the keyword-removal commit: WO-E104
added, WO-W201 retired.)

`@gc` is no longer part of the language: a developer never writes or mentions
it. GC-ness is decided entirely by inference (structural cycles + demand
promotion), which the earlier 7b commits made complete and precise.
- parser: `@gc` on a class is now WO-E104 ("GC-ness is inferred; run
`woc --dump-gc`. Remove it."). `is_gc` stays false; the class classifies by
inference. No `.wo` in the repo carries `@gc` anymore.
- types.ml: retired the WO-W201 machinery (suggest_gc_annotation,
has_recursive_structure(_type), has_unique_field, gc_suggestion_code) — it
suggested `@gc`, now obsolete since inference traces exactly those classes.
- runner.ml: deleted the 8 WO-W201 gc-suggestion test blocks; the @gc-exemption
test's `Cache` is made self-referential so inference classifies it gc without
an annotation.
- fixtures: dropped `@gc` from rc.wo (Cache demand-promotes via its escape),
elision.wo (Cache given a self-ref to stay structurally gc for the rc-elision
dump), pricing-demo.wo (PriceCache doesn't escape -> now owned), and the
abandoned-cycle/budget-steps corpus (Node is structurally gc). rc.wo keeps a
placeholder comment line so its line-indexed rc assertions hold. Goldens
re-blessed.
- docs: error catalog gains WO-E104 and marks WO-W201 retired; gc-cycle README
records the keyword removal.
Verified: woc-test 553/0 (was 566 minus the 13 retired WO-W201 checks),
test_diag 14/0, oop-e2e 79/0, employee 8/0, log-watcher 7/0. `git grep '@gc'`
finds only comments — success criterion 1 met.

- compiler: `insert Class { ... }` is a typed Ast.Insert in statement
AND expression position, sharing the ctor literal's field grammar;
typechecked with the ctor's omittable rule; result = the row id (Int)
- owner pass: the engine copies at the row API, so an insert BORROWS
its field values -- no transfer, no E304; node is trap-capable and
carries a live-mask drop entry like DbStub did
- emit: builtin 61 window = class-id const + one slot per DECLARED
field in declaration order; omitted defaults emitted, omitted ?scalar
gets WO_NIL_SCALAR, other omitted optionals the zero word; fresh
argument values reaped after (the push/set copy semantics)
- runtime: database/src/db.c executes via the choke-point row API;
rt.db/rt.wal opaque handles on wo_rt; WO_DATA=<dir> = replay
<dir>/shard-0.wal at boot + commit-before-ack per statement (the
builtin's return IS the ack until iteration 8 ticks); failed commit
un-applies the row and traps WO_T_IO; loader validates the class-id
slot (variable window documented in wob.h + format doc)
- the promised diff: trap/pricing-set-price-db-stub is now
run/pricing-set-price-insert printing engine-allocated ids;
durability smoke prints 1,2 then 3,4 across two WO_DATA runs
- old "bare insert is an Ident" unit test rewritten to the new
contract; runner's loader mirror accepts id 61; goldens re-blessed
- gates: oop-accept ALL CRITERIA MET, oop-e2e 71/0, woc-test 566/0,
wovm-test green, log-watcher 7/0

- database/src/wal.{c,h}: framed records len|crc32|payload|mark
("WOL1" written last -- no mark, no record), typed-row payloads
walking the class-table kinds (nested records, containers, nil
encodings), little-endian like the loader
- commit order verbatim from the shipped phase-D pattern: RAM apply,
stage, ONE pwrite + ONE fdatasync for the batch, ack after -- group
commit is everything staged riding one sync
- replay decodes straight into engine-owned values (no VM at boot)
and re-enters rows through the choke-point row API, so Task 4's
indexes will rebuild for free; next_id advances past replayed ids
this shard owns (wo_row_create_raw)
- torn tail = short/CRC-fail/no-mark/zero-len: intact prefix applies,
tear dropped whole, wo_wal_open positions AT the tear so the next
commit overwrites it; CRC-valid-but-undecodable = corruption, loud
- wo_wal_check: offline oracle, no engine needed -- the crash
battery's verifier
- test_wal 90/0 ASan+UBSan incl. five crash-battery rounds (fork,
insert/commit/ack-over-pipe, SIGKILL mid-stream: zero acked-but-
missing, zero acked-but-wrong); all runtime suites green, oop-e2e
71/0; binding doc WAL section + CODE-LOGIC + plan Task 2 checked
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- database/src/table.{c,h}: per-shard per-class slabs (256 rows,
malloc'd, never moved -- row addresses stable for 9b's row views),
occupancy bitmap, LIFO slot reuse, open-addressing id hash with
tombstones (ids never 0, never reused)
- field encoding walks the same .wob class-table kinds the VM walks:
scalars raw (WO_NIL_SCALAR passes through), Texts copied to db_text,
owned objects flattened recursively to db_rec, containers
element-wise; GCREF refused at encode (the GC bulkhead, defensively)
- two one-way copy gates: insert copies VM values in, read allocates
fresh VM values out -- no VM pointer in a slab, no slab pointer in
the VM, proven by mutating originals after insert
- id discipline: per table per shard, S+1 step N; owner = (id-1) % N;
N-parametric, runs at N=1 until iteration 8, tested at N=3
- choke points: wo_row_insert/wo_row_remove carry the INDEX HOOK
sites Task 4 attaches to; nothing else mutates storage
- runtime/Makefile links database/src into every wovm + test binary
- test_table 827/0 ASan+UBSan; oop-e2e 71/0; log-watcher 7/0;
binding doc docs/plan/oop-vm/04-db-binding.md; CODE-LOGIC.md beside
the code; plan Task 1 checked off

- 08-builtin-surface.md: containers copy a TEXT element/key/value; a freshly
built Text is the caller's to drop, a value read out of a place keeps its
owner; OWNED/GCREF still move and set's @gc retention gap stays open
- 00-status.md: the borrowed-Text double free is struck through as closed by
copy-on-push, with the concrete failure it fixed; new gap recorded — a
blocking accept/read swallows SIGTERM, which belongs to iteration 8's event
loop rather than a patch to the blocking calls

Found by driving the compiled log-watcher's third path — the MCP server. It now
answers real JSON-RPC over HTTP: initialize returns protocolVersion/serverInfo,
tools/list returns the full tool list (1049 bytes of generated JSON), and an
unauthorized request gets 401 {"error":"unauthorized"}. corpus 71/0, woc 565/0,
wovm gates green.
- lexer: `\r` and `\0` escapes. Without `\r` a program cannot write CRLF at
all — the server's `index_of(buf, "\r\n\r\n")` was searching for a literal
backslash-r, so it never found a header terminator and hung on every request
- parser: an interpolated sub-expression now mints node ids from the OUTER id
space. A fresh sub-parser started at 1, so `${...}` nodes collided with the
file's own nodes — and every side table (drops, moves, rc, masks, f_decl) is
keyed by node id. Surfaced as WO-E404 "ownership table names `headers`,
which has no register"; silent misattribution otherwise
- types.ml: `net.Conn` is a reserved SCALAR type (a file descriptor). It was
falling through as "some user class", i.e. WO_K_OWNED, so the frame would
DROP an integer at scope end
- types.ml: confident_typ knows `..` yields Text. Interpolation desugars to a
Concat chain, so without it every interpolated value looked underivable —
which is why the `+`-on-Text check missed two live sites in the workload
- `m[k]` on a map is now the OPTIONAL read (nil for a missing key), while
`get(m, k)` stays the asserting one that traps KEY. That is what makes
`let v = m[k]; if v != nil` — the workload's header lookup — work.
trap/missing-map-key now pins `get(...)`, and the surface doc records the
split
- json.encode of a `json.Value` emits it verbatim (kind 255): an echoed id was
coming back as "1" instead of 1
- disasm: TRY/ENDTRY render instead of ?OP32/?OP33
- status board: the push-of-a-borrowed-Text gap is now recorded with the
concrete failure it produces (tools/call tail_log), plus the leaked
temporary-record shell found in the same disassembly

Found by running the compiled log-watcher, not by reading code: the supervisor
rejected every cron line ("malformed schedule: * * * * *") because a `*` field
expands to 0 and `?Int`'s nil was also 0, so `a == nil` was true for a real
value. Both log-watcher subcommands now behave: `watch` alerts on a live file,
`run` reports SCHEDULE /var/log/backup.log: * * * * *. corpus 71/0, woc 565/0,
wovm gates green.
- a nullable SCALAR (?Int/?Bool/?Timestamp/?Id) spells nil as WO_NIL_SCALAR
(-2^62), not the zero word. Heap-shaped optionals keep 0 — a null pointer is
unambiguous. The value is -2^62 and NOT INT64_MIN on purpose: the compiler's
integers are OCaml's 63-bit natives, so INT64_MIN is not expressible there
(and `min_int * 2` silently wraps to 0 — the first attempt did exactly that)
- the class table marks such fields (WOB_FIELD_NIL_SCALAR in field_class), so
the runtime writes the right absence where it produces absence itself:
json.decode leaving a key absent or seeing `null`, and parse_int on
unparseable input (so parse_int("0") is now distinguishable from a failure).
json.encode renders a nil scalar as JSON null
- emit.ml: `nil` takes its word from its destination (annotation, field,
return type); a comparison against `nil` emits the literal with the other
operand's type, so ?scalar compares against the sentinel and ?heap against 0
- vm.c: EQS accepts a nil operand — two `?Text` values compare with it, and the
answer is "both absent is equal, one absent is not". Trapping there made
`a != b` on optionals unusable (it was trapping BOUNDS "null text" in the
supervisor's rescan). A non-nil operand must still be a real Text
- docs: both normative docs now state the heap-vs-scalar nil split and the EQS
rule; the stale duplicate vm_unwind comment is gone

docs/examples/log-watcher (1285 lines, 7 files) now compiles clean: 0
diagnostics, a 35KB .wob written. corpus 71/0, woc runtest 565/0, every wovm
unit gate green (both dispatch flavors).
- .wob v2: each class row gains three u32 per-field arrays — the field's NAME
constant, the CLASS it refers to (or the json-raw marker), and a container
field's ELEMENT kinds. json is then a runtime service driven by metadata
instead of per-type generated code. loader/emitter/disassembler/test
assembler all read and write v2; field-name constants are interned with the
rest of the pool (interning during serialization silently loses them)
- runtime/src/json.c (new): encode by static kind + object headers + class
table (nested records need no static knowledge); decode parses and BINDS
straight into the target class — keys matched to field names, nested objects
built as the field's class, arrays as a multi of the field's element kind,
unknown keys skipped, absent keys nil. Malformed input is nil, never a trap
- `as`: `json.decode(text) as T` is the one cast this language has (WO-E403
for any other `as`, and for a bare json.decode with no target type). Its
result is `?T`, which is why the decode and the target are one instruction
- json.Value: a reserved type name for a value the source does not inspect —
the raw JSON slice, kind TEXT, re-emitted verbatim by encode
- docs: 00-wob-format.md is now the v2 reference (class metadata, TRY/ENDTRY,
the whole builtin surface, WO_T_IO); 08-builtin-surface.md documents the
text/container builtins, the OS modules with their predeclared records, and
json's two documented limits (Bool encodes 0/1, floats truncate)
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- Modules: `use`/`pub`, directory-as-module, per-module symbol resolution (a
flat first-wins merge silently ran the wrong `pub fn` body), six reserved
stdlib namespaces typed UNKNOWN-BUT-RESERVED.
- Surface: `and`/`or` (own precedence tier, short-circuit, Bool-only), `${}`
interpolation desugared at parse time, `const`, break/continue with
drop-correct exits, do-while, inline-fn rejection.
- switch expr/stmt: required `default` over scalars/Text, arm unification,
EQ/EQS+JZ lowering, per-arm drop scopes with N-way JOIN-DROP; `default`
sorted last by a shared lowering order (textual order made arms dead).
- typedef records: structural, same shape = one class entry; `?name: T`
nullable-by-shape; emit_ctor fills omitted defaults; `type` as field name.
- Enum variants: all-bare unions = int ordinals; any-payload = one class
entry per variant, tag IS the header class_id (no header field, no format
bump); exhaustive switch without `default`; arity checked both directions.
- Payload escape modeled as move-out (pointer-kind fields only — a scalar
escape is a copy); caller reaps owned heap temps passed by borrow: two
unbounded LSan-blind leaks, 10.5 MB -> 1.5 MB flat over 300k iterations.
- Fixed en route, each with a RED repro: dead E209 builtin-arg check and
`int_to_text` missing from both types.ml builtin tables (both segfaulted
wovm), multi-file phantom double-report, emit_ctor's field temp clobbering
dst in tail position (pre-existing), warnings swallowed without an error.
- Two fenced VM builtins: `int_to_text` (13), `variant_tag` (14).
- 14+565 unit (was 14+401), corpus 71 (was 32) plain and under wovm_asan,
wovm-test + cli_smoke green. Log-watcher 307 -> 93 diagnostics (85 E101 /
4 E207 / 1 E208 / 3 W202); the 5 non-E101 residuals await Task 7 grammar.
- `woc` now emits `.wob` that `wovm` runs: emit.ml lowers the typed,
owner-annotated AST (scope-stack registers with a >64 WO-E401 diagnostic,
Lua-style call windows, ICALL by slot, dedup const pool, drop maps, line
tables, implicit terminators); disasm.ml backs `--dump-bc` goldens.
- Ownership lowering consumes the four owner tables verbatim; RESIDUAL is the
only source of borrow ops, coalesced per operand. Review caught the emitter
consuming only 2 of owner.ml's 4 residual producers — an assignment-anchored
aliasing violation ran to exit 0 instead of trapping; fixed, plus a backstop
raising WO-E404 for any residual region left unconsumed.
- Conformance harness `scripts/oop-e2e.sh` (`just oop-e2e`): four fixture
kinds with exact outcomes — byte-exact stdout, one WO-E### anchored on
`error CODE:`, numeric trap code, gc trace. 25 fixtures incl. pricing-demo
logic, the ownership suite, and DB_STUB's parse-but-trap. `tests/` un-ignored
so the corpus is actually tracked.
- `woc build` produces a self-contained binary: wovm copy + appended image +
20-byte trailer, self-exec via /proc/self/exe. Verified relocated outside
the repo, argless, and against adversarial trailer corruption.
- Milestone 1's five spec criteria all MET (`just oop-accept`). Criterion 3
closed by WO-E405 — the entry must return `Int`, since program mode already
says its return value is the exit code — which deletes the leak class
without adding return-type metadata to the format. `gc/held-cycle` retired:
an externally-held cycle is not expressible in a post-exit pump.
- New spec: inferred GC + incremental per-shard tri-color mark-sweep, retiring
`@gc` and reference counting. Story gains iterations 7b (that work) and 9b
(`@table`, relations, compiler-checked query); `.dev/reference` gains a
sparse System.Linq checkout. Priority: 5→6→7 (log-watcher) then 7b, 8, 9, 9b.
- Board renamed docs/plan/00-kanban.md -> docs/00-status.md and rebuilt: ▶ NEXT
PLAN pointer (iteration 4 — emitter, corpus, `woc build`) then six buckets —
stories, in progress, done, pending, discarded, learnings. It covered only the
Rust runtime before, so the whole OOP track was invisible. All 16 inbound refs
repointed; `Kanban:` banners renamed to `Status:`.
- New discarded.md (settled rejections with reasons: inheritance, `abstract`,
Money/SKU/Float, Dynamic/cast/macro/extern, AOT-to-C, Menhir, shared engine
state) and learnings.md (plumbed≠enforced, vacuous goldens, exit-0-wrong-
output, malloc-path ASan trick, deferred checks that never reach the VM).
- RECOVERED docs/plan/exploration/blue-green-vm/00-vision.md — gone from disk,
never committed (gitignored path), cited by five docs incl. principle 12.
Root cause was broader: all seven forward-roadmap plans in
docs/superpowers/plans/ were untracked and ignored, on one disk only. Dropped
the docs ignore rules with a do-not-re-add note; added __pycache__/*.pyc.
- Repaired broken links across docs/, 270 -> 36: fixes a regression from the
earlier reference/ -> .dev/reference/ move (relative paths at ../../ and
deeper were skipped), plus depth and reorg drift. The 36 residual point at
content that does not exist and need decisions, not paths.
- New spec docs/superpowers/specs/2026-08-10-logwatcher-gap-closure-design.md,
applied: `and`/`or` verdict row; Part 3 gains `env` (six modules), swaps
time.mono for iso/local, adds 22 bare core builtins; throw/time.mono/is cut
(0 uses in the sample). Plan 8: Task 2 gains and/or, Task 5 drops throw,
abstract+`is` task deleted, 8/9 renumber to 7/8. Plan 9 gains core builtins.
Plan 10 gains the 307 -> 0 diagnostic gate. WO-E205 re-filed unreachable-by-
design. types.ml header drops its false satisfaction-set claim. 00-code-
review.md reduced to a stub — its rival Phase 1-4 roadmap retired.
Completes plan 2 Tasks 7-8. owner.ml: mutable-value-semantics flow analysis
producing the four plan-3 emitter tables (moves, drops incl. LIVE-MASK for trap
unwinding, rc with elision, residual borrow sites) plus WO-E301-304 two-site
diagnostics. Alias questions run over canonicalized places, so a double-mut
reached through let-bound aliases lands in the residual table like the direct
form; dump.ml's contract notes the emitter must coalesce guards per operand.
main.ml: directory discovery, cross-file programs (symbols merge before bodies
check), diagnostics ordered by (file,line,col), new WO-E214 for a name declared
in two files. New docs/plan/oop-vm/01-error-catalog.md (14 emitted + 10 reserved
codes), un-ignored so both plan tracks can cite it; justfile regains woc-*.
builtin_scalars is now the five that work: Int, Bool, Text, Timestamp, Id.
Money/SKU/Float and the abstract_types allowlist are gone — `abstract` never
lexed, and Float had no literal syntax and no wob kind, so no value could exist.
Fixtures and samples retype Money->Int, SKU->Text. The abstract newtype feature
is rejected outright (verdict row adopt->reject); haxe-parity Task 7 keeps `is`.
nullable-types-implementation.md corrected: ?T is plumbed but UNENFORCED
(E211-213 declared, never emitted; probe exits 0), handed to haxe-parity Task 6
as next work item. Records all 10 dead codes incl. E205 — interface satisfaction
is unchecked. crates/rt keeps its Money/SKU fixtures (opaque strings, Stage 2).
Gate: build warning-clean, 14 + 264 checks 0 failures, pricing golden exit 0,
docs/examples histograms unchanged (13/70, zero WO-E225).
