- docs/00-dependency-graph.md: three mermaid graphs — story iterations
(hard edges only; 18 is the only spec-approved node with all
prerequisites green), framework v1 ledger items (three recurring
gates: net seams, crypto fork, iterations 8/11; nine slices startable
today in any order), framework v2 internals (cache/flags independent,
transaction{} is the critical path, jobs compose on it)
- maintenance rule: node classes update in the same change as board rows
- board links the graph up top; spec 18 banner -> APPROVED, plan next
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- framework README core checklist expanded into the v1 STATUS LEDGER:
seven categories (transport, routing, request/response, context &
middleware, storage integration, security, crypto), every item
marked done / partial-with-named-gap / candidate / parked-behind-8-11
/ needs-runtime-seam
- verified before labeling: BODY_MAX caps headers AND body (size limits
done); net has no timeout or unix-socket or peer-address surface
(runtime seams); language has NO bitwise operators, so SHA/HMAC/CRC32
must be C runtime builtins or bit ops land first (fork to brainstorm);
radix routing waits for 9e to measure the linear scan first
- crypto hard stop recorded: HS256 unlocks and nothing past it
- memory-rich features relabeled FRAMEWORK V2 = iteration 18 (story +
spec banners + board rows); v1 gaps land as slices per the ledger

- Part A transaction: one wal_commit at block end over the existing
staged batch; reads see own writes (RAM stays authoritative); trap
unwinding out = abort (undo list: insert->remove, update/delete->
pre-image, captured before RAM apply, txn-only cost); try inside
keeps the block alive; WO-E110 lexical nesting, WO_T_DB dynamic;
no new opcodes, no .wob bump (internal builtins + catch-frame-shaped
abort marker); E108/E109 stay reserved for parked 17
- Part B: cache.wo (ttl_ms/cap, lazy time.now-ms expiry, FIFO over LRU
with the tradeoff stated, Text values via json); flags.wo (@table
wf_flags, on as Int 0/1 - Bool columns unproven, read-through map,
set updates table+map); jobs.wo (@table wf_jobs, enqueue composes
with transaction, JobRunner interface, App.jobs(take r, budget),
Dispatcher.idle() called post-accept PRE-PARSE - deterministic for
the SIGKILL durability proof, unlike after-response)
- web-app demo: transactional order+confirm enqueue, GET /jobs count,
POST /flags/:name with a flag-gated header on the product list
- gate: SIGKILL-after-201/restart/drain proof + flags persistence;
corpus carries transaction-commit/abort + WO-E110 + cache-ttl
(stamps injected, no sleeps)
- board row 18 -> spec written, awaiting review

- http/multipart.wo: RFC 7578 whole-body parsing within BODY_MAX —
boundary from the raw content-type (quoted or bare, key
case-insensitive), parts split on --boundary, each part = headers,
blank line, content; filename + per-part content-type kept (lowercased)
- strict malformed-is-nil: no closing --boundary-- marker, a part
without content-disposition, missing blank line, no boundary param,
wrong media type — all nil, the caller's 400
- part_named(parts, name): first matching field's content, caller-owned
- web-app CreateProduct now accepts multipart/form/JSON (curl -F shape)
into the shared insert path
- probe 13/13 + 3x reuse loop (fields, crlf-in-content, quoted boundary,
file part, zero-part close, five malformed shapes) release + ASan
- gate grows 19 -> 21: multipart create 201, missing closing marker 400
- README: multipart row ✅ (all three body hooks done), limits updated;
story 16 + board record the landing
- gates: web-app 21/0, oop-e2e 89/0, deps-accept 8/0, log-watcher 7/0,
employee 8/0, woc-test green
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- media_type(req): content-type lowercased, "; charset=..." stripped,
"" when absent — the content-negotiation hook
- form_values(req): application/x-www-form-urlencoded body -> decoded
pairs through the existing query decoder ('+' as space, %XX); nil on
any other content-type so a JSON body is never misread as a form key
- web-app CreateProduct accepts form OR JSON; shared create_product
insert path; field/number validation answers 400
- probe 7/7 (plus/pct decode, empty value, case + charset param, json
and missing content-type nil, empty body, media_type strip) + ASan
- gate grows 17 -> 19: form create 201 with decoded name, non-numeric
price 400; hit() gains a content-type argument
- README: checklist row form ✅ (multipart stays candidate), limits
paragraph updated; story 16 + board record the landing
- gates: web-app 19/0, oop-e2e 89/0, deps-accept 8/0, log-watcher 7/0,

- App.get/post/put/delete_(pattern, take h: Handler) — the take-interface
shape probe-proven release + ASan before landing; retires plan-16
deviation 1; delete_ because delete is the query keyword
- dispatch matches path-first: wrong method on a known path answers 405
with Allow in registration order; unknown path stays 404
- HEAD routed as GET, body suppressed, Content-Length names the body a
GET would carry (serialize gains head_only)
- Logging middleware (request line to stderr) ships in router/
- set_header(mut r, name, value) — the builder escape hatch
- web-app registers through the helpers (dogfood); README documents all
- gate grows 14 -> 16: 405+Allow, HEAD-vs-GET content-length equality
- all gates green: web-app 16/0, woc-test 540/0, oop-e2e 89/0,
deps-accept 8/0, log-watcher 7/0, employee 8/0
- board/story: iteration 17 parked (spec+plan ready on library-internal),
16 carries the v1-polish landing, order list updated
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- NEXT PLAN step 1 now carries the reason: 17's edit targets (framework
sources, [deps] resolution in main.ml, just web-app gate) exist only on
the web-framework branch; unmerged start = branch stacked on unreviewed
branch
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- NEXT PLAN rewritten: iteration 17 is the goal slice (merge branch, spec/
plan, kind = "library", internal/ WO-E1xx, framework reorg, gate list)
- previous NEXT PLAN retitled "Landed 2026-08-15 — the executable milestone";
all six measured items were already done, board rows were stale
- board row 7: in-progress -> landed 2026-08-15 (ASan-clean, SIGTERM, fd-flat,
soak, just log-watcher 7/0); iteration 07 story banner updated to match
its plan doc's done banner
- in-progress table now carries iteration 17 spec/plan
- implementation order re-sequenced for framework goal: 17, 9c/9d, 9e, 8,
9f, 11 (+ h2c unparks), 10, 12, then 14/9g demoted (skillhost no longer
the driving workload), 13 + parked drain last
- story notes record the shift and the new order
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- new "Implementation order (sequenced 2026-08-20)" section in 00-status.md
pending bucket: 7-finish, 17, 9g, 14, 9c/9d, 9e, 8, 9f, 11, 10, 12,
13 + parked drain
- forcing rules recorded: 9f after 8+9e; 9c precedes 10; 9d folds into 9c;
12 after 9+10; 11 rides 8's scheduler; h2c behind 8/9f/11; post-12 park
directive unchanged
- 9e placed before 8 so restructure/perf work has a signed baseline
- 14 early as next driving workload (stdlib-shaped, shard-independent)
- story 00-story.md notes point at the sequenced list

- fork 1: library-ness manifest-declared, kind = "library", default program
- fork 2: privacy = Go internal/ directory rule, named diagnostic at use
- fork 3: dep-boundary-only scope; Go subtree rule recorded as later tightening
- fork 4: lib+bin dual — library default action is check, explicit build works
- Go-inherited rule pinned: internal type in public signature allowed, no check
- impact analysis added: framework loses --emit workaround, plumbing under
internal/; compiler = two seams (driver kind + dep-use refusal WO-E1xx)
- VM zero impact by construction: no .wob change, libs compile whole-program
into consumer image, internal modules still emitted (privacy strips nothing)
- GC zero mechanism impact; pinned: inference stays whole-program, app usage
can promote dep classes, internal/ invisible to gcinfer — intended, not bug
- board + roadmap rows: needs-refinement -> forks settled, spec/plan next

Brainstorm outcome, deliberately NOT implemented (developer decision: keep
as an iteration needing further refinement). Records:
- the two gaps iterations 15/16 exposed: library-ness is implicit (a
no-main project fails woc <dir> build mode — the framework is verified
via an --emit workaround) and the dep boundary leaks internals (pub has
no dep-private tier: parse_request is as importable as Handler).
- the conventions corpus: Go (package decides program-ness; cmd/;
internal/ = directory-shaped privacy, zero keywords) vs Rust ([lib]/
[[bin]] manifest targets; pub(crate)-family keyword visibility). Doctrine
fit points at Go's shape with an explicit manifest key (writeonce HAS a
manifest; explicit beats inference in errors).
- four open forks for the spec: kind declaration form; internal/ vs
pub(lib) vs export-allowlist; dep-boundary-only vs Go's subtree rule;
lib+bin duality. Draft acceptance criteria; web-app 14/0 as the
regression gate. Roadmap + board rows added.

.wo-deps/wo.lock behavior, offline-when-locked, --update-deps, flat-only.

story 15 header records the landing; 08-project-structure notes
.wo-deps (gitignored) + wo.lock (committed); plan checkboxes all ticked.
(One self-inflicted casualty during this task, restored from git before
commit: a buggy doc-edit script truncated 08-project-structure.md; the file

5 tasks, words-only per house rule, each with its verify step: (1) manifest
grows the [deps] section + one-line inline-table value (only under [deps]);
(2) resolver — git-binary fetch into .wo-deps/, wo.lock pinning, warm-path
offline guarantee, drift diagnostic, --update-deps, guard rails (transitive
refusal, non-writeonce dep, name collision WO-E107, all fetch failures
WO-E106); (3) multi-root discovery + module_of prefixing dep roots by dep
name + entry restricted to the app's own files; (4) scripts/deps-accept.sh
gate over file:// remotes (8 checks, network-free) + just recipe; (5) docs
closeout (catalog E106/E107, README deps subsection, board/story/structure).

Brainstorm outcome (forks locked with the developer):
- TLS: proxy-terminated (nginx/caddy gives browsers TLS+ALPN+h2; the
framework speaks HTTP/1.1 behind it) — zero TLS in the toolchain, no
doctrine fight; homegrown TLS refused outright.
- Dependencies: a real mini package manager — wo.toml [deps] with exact-rev
git deps, wo.lock, .wo-deps cache, `use <dep>` as a module root; fetch by
shelling to the git binary (no network code in woc); flat-only v1.
- HTTP/2: v1 is HTTP/1.1 keep-alive; h2c is the parked successor behind
iterations 8/9f/11 (multiplexing needs a scheduler to pay off); the
bytes/buffer type rides with it, not v1.
- Handler model: no function values by doctrine, so Handler/Middleware are
structural interfaces (ICALL dispatch, WO-E205-checked); middleware returns
?Resp and rides the shipped ?T narrowing.
- Incubation: framework at docs/examples/writeonce-framework/, consuming
storefront at docs/examples/web-app/ importing it THROUGH [deps] — the
sample exercises fetch -> lock -> build -> serve -> durable-restart.
- Iteration 10 relationship: service blocks later LOWER ONTO this library.
Files: specs/2026-08-18-web-framework-design.md (A deps normative, B
framework normative, C h2c parked); stories 15-deps-package-manager.md +

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;

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;

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.)

Analyzed the full 131-file docs tree (4 parallel classifiers) against the
shipped woc/wovm toolchain. Removed 21 stale docs, kept all intentional
history (Rust-track plans/done, the runtime/database design series cited by
current specs, syscall/postgres/assembly/c-runtime studies, discarded/
learnings). Deleted:
- old-runtime "front door": writeonce-pl.md, runtime/wo-language.md
(pitched the Rust wo runtime -- REST/LiveView/SQL+Cypher -- as the current
language; contradicted the new README)
- v1 design set: 02-recovery, 03-data, 04-ui, 05-datalayer,
06-markdown-render, 07-ssl; runtime/database/05-go-sdk
- future-scope/ai-agents-content-management (unfinished old-runtime CMS)
- the ##ui/.htmlx LiveView frontend track (product decision to abandon):
9 plan/exploration/ui/*, plan/14-mvc-ui-implementation,
superpowers/plans/2026-08-01-ui-htmlx-live; 13d pricing-UI board row
Tree left link-clean: 46 dead links to the removed docs neutralized to plain
text or deleted as pure see-also bullets across 20 kept docs; whole-tree
link-resolving scan reports zero links to any deleted file. Removal recorded

- frames a writeonce port of ~/projects/skillhost (C++ MCP host that
links libllama in-process, discovers filesystem skills, runs their
scripts confined) as the sample that drives host capabilities into
the open — the way log-watcher drove the systems stdlib
- names each gap as a candidate iteration (surveyed 2026-08-16 vs the
running compiler + skillhost source):
- Blocker A: in-process native-lib FFI (no FFI today) — fork:
FFI-as-language vs out-of-process model driver over proc/net+json
(llama-server, needs nothing new); leaning out-of-process
- Blocker B: stdio transport — no stdin/stdout builtins; port uses
a TCP socket meanwhile; io.stdin_read/stdout_write a candidate
- Blocker C: bounded/killable subprocess — proc.run has no timeout/
signal/process-group kill; smallest + most broadly useful, do 1st
- partials: recursive fs walk, exec-bit check, symlink-resolving
confinement (realpath) — one small fs-metadata iteration
- records what is already expressible (catalog via @table/9g skill-
catalog, discovery, frontmatter text-parse, config, single-thread
serve, context-gate arithmetic — no VRAM query needed)
- out of scope: in-process libllama/CUDA, VRAM introspection, exact
sampler chain / per-turn memory clear
- roadmap + board rows added

- method: an embedded-SQL app is a grammar corpus; catalogue what it
actually uses and add only that, translating its statements 1:1 as
the acceptance (the postgres/System.Linq reference pattern applied to
a whole application)
- corpus #1 = ~/projects/skillhost (C++ MCP host, embedded SQLite skill
catalog): surveyed, entire SQL footprint is one file — 1 table, a
single-row parameterized INSERT, 4 SELECTs. 3 of 5 statements already
run on the 9b surface (insert, where name==?, order by name; PK ≈
@unique). Exactly 2 are the real gap:
- whole-query `count` (group-free; the degenerate aggregate, NOT
the parked group-by)
- correlated `not exists` subquery (skillhost's roots-of-the-tree)
- notable finding: skillhost's NOT EXISTS is naturally a `backlink`
emptiness in writeonce (children backlink + len==0), so the corpus
may be fully expressible once len(query) is confirmed — the iteration
may collapse to "confirm len(query) + add exists"; forks record this
- explicitly parks everything skillhost does NOT use (join/having/
offset/distinct/CTE/window/union/upsert/returning/json/fts/triggers)
and the full group-by; each enters only when a corpus demands it
- acceptance: docs/examples/skill-catalog mirroring skillhost's schema
+ its 5 catalog ops as writeonce translations
- roadmap + board rows added

- FK restrict: deleting a row a non-nullable `ref` still points at traps
WO_T_FK (11), catchable. The compiler now records a `ref` field's
target class in the class-table field_class metadata; the engine
(wo_row_has_referrers) scans referencing scalar columns before a
delete. Correctness-first full scan; the backlink-index optimization
is recorded for later
- docs/examples/employee now COMPILES AND RUNS all six modes against a
WAL-durable database: seed (+@unique trap across restart), report
(per-dept aggregates + payroll), staff (unique probe + backlink +
ref nav), raise (update-through-row), drop (FK restrict), and
persistence via replay
- group-by SYNTAX parked to a future iteration (user decision): the
report mode is hand-rolled from the shipped primitives meanwhile
(same numbers). "table relations and FK" is complete
- scripts/employee-accept.sh (8 checks) + a `just employee` module;
manifest parser tolerates iteration 9c's [share]/[[share.clients]]
sections so `woc .` builds the sample on this branch
- fixtures trap/db-fk-restrict (code 11) + run/db-fk-restrict-catch;
oop-e2e 79/0, woc-test 566/0, 15 runtime suites, log-watcher 7/0,

- captures the toCSV/reflection thread: principle 13 forbids runtime
reflection, so a generic serializer can't be a user-written function;
Rust answers with derive macros (compile-time codegen), and
json.encode is already a single hand-built instance of exactly that
- iteration generalizes json.encode's mechanism into a reusable derive
facility: @derive(Json/Csv/Eq/Hash/Show) -> the compiler generates
per-type routines from the class-table metadata it already emits,
monomorphic, no runtime type tag, no dynamic dispatch
- closes the query-result-serialization gap
(csv.encode(from e in Employee ... select e)) that has no expression
today; acceptance requires json.encode retrofitted onto the framework
with byte-identical output, and disassembly proving no reflection
- four forks: request surface (lean @derive annotation), invocation
(lean compiler-recognized encode builtins, no UFCS/methods), Eq/Hash
sharing the engine's key comparison, static applicability checking
- out of scope: full trait/typeclass system, user proc-macros, general
generics, cross-channel derive -- a CLOSED compiler-known derivable
set, the pragmatic 80% without the type-system weight
- numbered 13 to echo the principle it lives inside; roadmap + board

- 9e durability/throughput/scale: the measurement backbone -- run the
employee program, restart to prove persistence, benchmark read/write
through compiled .wo, ~1M-row mixed load with throughput floor + p99
ceiling + flat RSS; the gate every optimization signs (before/after
delta required, no measured delta = not accepted)
- 9f io_uring group-commit: replace fsync-per-commit with batched
io_uring durability overlapped on shard threads; same ack-after-
durable contract, crash battery unchanged, automatic fsync fallback
on kernels without it; deliberately LAST (needs 8's threads to
overlap and 9e's baseline to beat)
- wired the existing levers into the arc: iteration 8 (thread-per-core)
= "optimize multithreading", 7b (mark-sweep) = "implement GC" --
each now gated by re-running 9e and recording the delta
- explicit sequence recorded in 9e: 9b lands -> 9e baseline -> 7b
re-bench -> 8 re-bench -> 9f re-bench
- roadmap + board rows for 9e/9f; four forks each for the specs
(load generator, absolute vs relative budgets, what "1M" means,
durable vs RAM headline; ring model, liburing vs raw, batch
boundary, fallback testing)

- promotes 9c's identity fork to its own iteration: program identity
is a keypair (first-boot generated into WO_DATA, 0600, printable
fingerprint); A's [share] grants name PUBLIC KEYS, B pins A's key
in [connect.a]; mutual challenge-response, fresh nonces, transcript-
hash signing (protocol tag + fingerprints + nonces + channel)
- acceptance criteria: registered-key attach carries 9c rights
unchanged; unregistered key refused pre-statement with fingerprint
logged; same-uid-wrong-key refused (uid SUPERSEDED, not
supplemented); impostor on A's socket path aborted by B's pinned-key
check; handshake replay refused; rotation = manifest change
- four forks recorded: crypto provenance (lean: vendored compact
Ed25519 as the one sanctioned vendored component), keygen home
(lean: first-boot into WO_DATA), signed-transcript layout, uid
survival (lean: keys only, peer-cred demoted to log enrichment)
- out of scope: transport encryption, CA machinery, key escrow,
root-attacker protection
- plan folds into 9c's when specced (neither ships alone); 9c fork 3

- program B attaches to running program A's persistent database via an
IPC string in B's wo.toml [connect.<name>]; A registers clients by
name with read / read+write rights in its [share] manifest section;
unregistered = refused at connect, under-privileged = catchable trap
- doctrine preserved: A stays the single writer -- B's statements
execute inside A through the same choke-point row API, B never
touches A's WAL or slabs; typed statements checked by B's compiler
against A's table shapes, schema handshake at attach
- four forks recorded for the spec: channel carrier (lean: unix
socket + SO_PEERCRED), how B's compiler learns A's shapes (lean:
project reference + live handshake), grant granularity (lean:
whole-db rights, name+uid identity), blocking semantics (lean:
blocking round-trip, stop-flag rule applies)
- acceptance sketch: employee sample as A, a thin employee-report
client as B (read-only GroupBy over the wire) + audit-log writer
exercising the rights matrix
- slots after 9b (shares its typed surface), before 10 (HTTP is the
external face; this is the writeonce-native one); prior art:
04-client-api.md wire protocol + the WAL's value encoding
- roadmap + status board rows added

- spec settles 9b's three forks: SQL/Cypher layer superseded as the
program surface (design history + wo-db engine-semantics reference);
comprehension syntax desugared at compile time (no function values);
System.Linq = operator vocabulary + edge cases, PostgreSQL = execution
+ integrity vocabulary (both references surveyed 2026-08-15)
- aggregate semantics normative: count/sum total 0 on empty, avg/min/max
are ?T with nil (empty is data, not a fault); nil skipped; sum wraps
like language arithmetic; GroupBy lowers as group-and-reduce
(AggregateBy shape), transition/finalize ABI from nodeAgg
- relations: ref = FK with direct-index-probe check (nil passes,
unchanged-key skips), backlink = secondary-index scan, delete is
restrict-only; nil never joins, nil is a legal group key
- lowering: the compiler is the planner — queries become bytecode loops
over cursor/group builtins, longest-prefix index selection, no plan
tree, no SQL text in the image (disassembly-provable)
- plan: 6 tasks gated by a new docs/examples/employee sample
(Department/Employee, @unique, composite index, ref/backlink,
GroupBy report mode) with its own acceptance script + crash step;
blocked on iteration 9's engine plan
- story 09b + status board updated; 02-wo-language.md carries the
supersession note

- Task 5: net.close on every path out of a serve iteration (400
included) and the listener on stop; measured 4 -> 54 fds over 50
requests before, 4 -> 4 over 200 after. The loop's comment claimed
the iteration-end drop IS the close -- wrong twice (net.Conn is a
scalar, and a drop would not close an fd); it now says what is true
- Task 6: LW_SOAK=<seconds> in the acceptance script -- each mode under
load, resident+descriptor deltas against a WARMED baseline (warm-up
includes load: cold-to-high-water is not growth), 256 KiB / zero
tolerance; LW_ACCEPT_WOVM soaks another build
- the soak caught ~1.6 MiB/min of in-arena leaks ASan cannot see (the
arena is one allocation to LeakSanitizer); an arena size-class
census + pointer trace attributed five bugs:
- jparse_string sized every decoded string at "rest of the input"
and relabeled len after -- blocks filed on free lists their next
allocation never reads (fs.read_all's mis-size, again); copy out
exact, free at the taken size
- `!=` never dropped fresh operands (headers["authorization"] !=
"Bearer ${key}" leaked both sides per request); Ne now reaps as Eq
- an Int interpolation segment is a fresh int_to_text, not a borrow;
is_borrowed_value_t asks the segment's type
- json.encode(Ctor{...}) had no owner -- record + both field copies
leaked per tool call; its bespoke lowering now drops the argument
- a discarded expression statement owns its result: `pop(lines);`
leaked the popped element; reader builtins excluded
- after: arena live bytes flat per request on every handler; release
soak 30 s per mode watch 0 / run 0 / mcp +20 KiB, descriptors flat;
ASan build flat at 14600 KiB across 601686 requests in 90 s past its
~1200-request quarantine warm-up

- blocking stdlib calls that PARK (net.accept, socket read/write,
time.sleep, a child wait) no longer restart the syscall when the
stop flag is set on an interruption: a server sitting in accept
ignored SIGTERM and only `kill -9` ended it
- a stop is NOT a trap -- builtin.h's WO_SYS_STOPPED carries no error
record and no catch handler sees it (`try` must not swallow
SIGTERM); the VM unwinds the whole stack through the same drop
machinery an uncaught trap uses, so nothing leaks on the way out
- wo_vm_call gained a third outcome (1 = stopped); the CLI maps it to
the status the program's own `return 0` would have given, and a
regular-file read keeps its plain EINTR retry -- it does not park
- an ASSIGNMENT was not an ownership boundary: `api_key =
j.mcp.apiKey` moved the field pointer into the local, so the local
aliased the record and the first unwind freed the same string twice
(SIGSEGV in class_free). `let` copied a Text place, assignment now
does too -- the same double free was latent on the normal exit path,
hidden by the order the compiler happens to emit drops in
- log-watcher-accept is 7 checks: the seventh is the stop itself, with
the hard kill demoted to a fallback whose use is the failure
- measured under ASan: mcp parked, mcp after traffic, watch and run
all exit rc 0 with zero leaks; SIGINT behaves as SIGTERM

- program mode built the entry's `multi Text` of arguments and never
freed it: the entry only BORROWS a parameter (never a `take`, and
the drop tables never drop one), so the runtime that built the
container owns it
- dropped after the entry returns and after a trap alike -- the
container outlives the unwind; `multi_free` recurses, so the
argument strings go with it
- one site covers both invocation shapes: `self_rc` picks the argv
offset, it does not build a second container
- measured: watch, run and the full MCP mix now report ZERO leaks
under ASan -- the clean baseline the soak (Task 6) reads against

- the drop tables track bindings only, so six shapes had no owner: a
comparison operand (`if parse_expr(s) == nil` abandoned a schedule
record and its five containers per cron line), a borrowed call
argument (a 1 KB string per MCP request), a container read's copy,
a loop's iterable, a projected record, and any of those escaped by
a `return` from inside the statement that built them
- `c[i]` is the one place expression whose register holds a COPY:
no second copy at a boundary (`let u = tokens[0]` copied twice and
abandoned the first), and a drop where every other place is left be
- never drop an argument register after a CALL — the callee's frame
overlaps it; the reap moved into call_window's pre-call stash
- a statement-owned temporary is parked in a LOCAL slot: a loop
reclaims every temp for its body, and the end-of-statement DROP was
releasing the loop counter instead of the record
- reader builtins (get/latest/key_at/val_at) keep arg0 alive — their
result points into it — but their key argument is ordinary
- measured: run 2 112 B -> 64 B, flat 8 s to 20 s; MCP mix 21 312 B /
63 -> 64 B / 1; every handler flat from 2 to 6 requests; the 64 B
left is Task 3's argv container

Measured on the workload's supervisor mode, eight seconds, clean SIGTERM exit:
run 1 051 040 B in 24 allocations -> 2 112 B in 19; watch 128 B in 2 -> 64 B in

- owner.ml: `oclass_of` called `Text` a builtin scalar, so it was Copy and NO
Text local was ever dropped — that, not the missing stdlib table, was the
leak. Text is now Owned, which forces an answer for what it does at an
ownership boundary, and the answer is uniform: it is COPIED. Into a
container (push/set/`m[i] = v`, already true), into a field (SETF), out of a
function (return), into a binding (`let s = other`), and into a loop cursor.
The source keeps its value; a freshly built Text stays the caller's and is
dropped at the site
- owner.ml: resolve_callee answers for three shapes it never knew — reserved
stdlib members, builtins, and a class's `static` members — so their results
get a type, an owner and a drop
- vm/builtin: WO_B_TEXT_COPY, the one new builtin the rule needs; SETF copies a
TEXT field in; emit copies a Text read out of a container, bound from a
place, returned from a place, or loaded into a cursor, and drops a freshly
built one after a copying store
- sysio.c: fs.read_all/net.read allocated their cap then relabelled the buffer
with the short length — but wo_str_free sizes a block by its len (no size
headers, obj.h), so a 1 MiB buffer wearing a 30-byte length went onto a
32-byte free list and never came back. They copy out at the true size now
- two regressions the corpus caught, fixed in the same pass: a @gc value read
out of a container is a plain borrow, not an rc-counted alias; and push's @gc
escape is keyed on "push is not a user-declared fn" rather than "the callee
did not resolve", which stopped being true once builtins resolved
- docs: Task 1 closed in the executable plan with its before/after numbers, and
the status board's item 1 records the deeper root cause
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Every remaining item is now traced to a measurement on the sample; anything the
sample does not exercise is deferred by name with the measurement that says so.
- new plan docs/plan/compiler/2026-08-14-logwatcher-executable.md — six tasks
between "it runs" and "you can leave it running": the ownership pass learning
stdlib return types (>1 MB leaked in 8s of `run` mode, one fs.read_all
result), dropping a projected temporary (`for e in parse_dir(d).entries`
leaks the shell per rescan), the runtime's own argv container (128 B every
run), honouring the stop signal in blocking calls (a server in accept ignores
SIGTERM), closing accepted connections (net.close exists, unused), and a soak
that would have caught all of it. Opens with the measured starting point and
closes with an explicit out-of-scope list
- story 7 (log-watcher proof): status banner separating the met compile-and-run
half from the executable half, plus a new Given/When/Then — clean SIGTERM
exit, zero leaks, flat RSS and descriptors across a soak
- story 5: grammar half landed, strictness half deliberately deferred
- story 6: landed for the surface the workload uses, with the two lifetime
defects it exposed pointed at the new plan
- story 7b: recorded as off this workload's path, measured — the sample has no
@gc class, 0 RC_INC/RC_DEC against 78 DROPs
- 00-status.md: NEXT PLAN is the executable list; story table and in-progress
row point at the new plan; deferrals carry their evidence
- plan 8 (haxe-parity): banner now says on hold behind the executable plan, and
its task states are corrected — Task 5 shipped, Tasks 6 and 7 are half done
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- 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
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- docs/00-status.md: NEXT PLAN is now iteration 5's strictness half (?T forced
handling, pub(read) writes, using, #if) plus an ASan run over the workload;
iterations 6 and 7 marked landed; a "Landed 2026-08-14" section records what
actually shipped, and a new known-gaps block records what did not — lenient
optionals, unenforced pub(read), the borrowed-Text-into-container hazard,
json's Bool/float limits, net fd lifetime, no ASan over the workload, and no
corpus fixtures for the new surface (by direction: the sample is the test)
- runtime/src/CODE-LOGIC.md: file map, the loader-is-the-only-validator and
traps-never-leak invariants, the catch stack, records the VM fills but cannot
name, class metadata + json, program mode, and where to look when it breaks
- compiler/src/CODE-LOGIC.md: the pipeline, why there are two type derivers and
the stay-silent-when-underivable rule, how contextual values get a
destination, the node-id/label contract between owner.ml and emit.ml, the
four kinds of qualified call, predeclared records, the constant-interning
trap, register discipline, and how to verify a change

docs/examples/log-watcher now COMPILES AND RUNS: `wovm lw.wob watch app.log 2 1`
tails a live file, classifies levels and fires its alert
("last entry is error, quiet for 2s"). corpus 71/0, woc 565/0, wovm gates green.
- program mode: the entry is `fn main` taking nothing or one `multi Text`;
runtime/src/main.c builds that list from the program's own arguments (not
the program name, not the image path) and the entry's return value is the
process exit code (low byte); the loader accepts a 0- or 1-arg free-fn entry
- `+` on Text is now WO-E201 pointing at `..`. This was a memory-safety hole,
not a style nit: the emitter lowered it to ADD on two heap pointers, and the
workload's own `out = out + char_of(c)` produced a wild pointer that
segfaulted the VM inside starts_with. Reported off confident types only
- `x == nil` / `x != nil` lower to EQ (a word compare), never EQS: nil is the
zero word and EQS dereferences its operands, so a nil guard would trap
instead of answering
- docs/examples/log-watcher: seven `+`-on-Text sites corrected to `..`
(logtail sanitize, mcp header/body/carry assembly, supervisor detections
line) — the sample was carrying the Haxe habit, and the language reserves
`+` for arithmetic by doctrine
- wovm CLI takes arguments after the image path (`wovm <file.wob> [args...]`)
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- `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.
