- router/router.wo: Handler (handle(req) -> Resp) and Middleware
(before(req) -> ?Resp; nil = continue) structural interfaces; Route/Mw
record classes built as ctor literals at the registration site — the
ownership shape the corpus pins (run/container-owned-move);
route_match with :param captures over '/'-split segments (empties
dropped, first mismatch wins).
- app.wo: App holds the middleware chain + route table (take-push),
satisfies http's Dispatcher, dispatches middleware-then-first-match,
fills the captures onto the borrowed request in place (Dispatcher takes
`mut req` — the borrow checker rightly refused rebuilding a Req from
borrowed maps; captures collect locally so a failed match never touches
the request), 404 fallback, serve(host, port) delegation.
Verified against a throwaway app (not committed): middleware 401
short-circuit without the token; /things/:id captures 42 into the body;
unknown path 404; a DIV0 handler answers 500 and the next request is
served; SIGTERM clean. Framework image emits at 12161 bytes.

- http/parse.wo: bounded-read buffering to the header terminator, then
exactly Content-Length body bytes; %XX decoding ('+' = space in query
strings only, malformed escapes pass through — parsing stays total);
path/query split with decoded pairs; header names lowercased; the
three-state Parsed record (closed / malformed / request) with keep-alive
carry-over — bytes past this request belong to the next one on the
connection.
- http/serve.wo: Dispatcher interface (the router's seam), status/reason
serialization with computed Content-Length, and the blocking loop:
malformed -> 400 + close; a trapping handler -> 500 AND the loop lives;
fds closed on every path; env.stopping() honored.
- Connection policy discovered by probing, not assumed: a parked keep-alive
connection BLOCKS accept on a single-threaded server (probe: client 1
idles open, client 2 starves). Policy: serve PIPELINED requests on one
connection (carry non-empty), close when the client would idle; a proxy
reconnects. README states it.
Verified against a throwaway echo app (not committed): %20 query decode;
two pipelined requests -> two responses on one connection; DIV0 handler ->
500 and the NEXT connection served; GARBAGE -> 400; SIGTERM stops clean.

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;
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

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.

Structural inference (2a) covers cyclic classes; this adds the DEMAND half for
the acyclic-but-aliased case, so @gc is now redundant everywhere.
- owner.ml: a `promote` sink on ctx. In collect mode, a class value that would
raise WO-E304 (escape) records its class instead of erroring — because a
class that MUST escape cannot be owned (second-class borrows can't be stored
or returned), so it must be traced. `class_of_ty` extracts the class from the
escaping local's type. analyze/analyze_fn take ?promote.
- main.ml typecheck_all: after structural injection, a fixpoint runs ownership
in collect mode over every file, unioning promotions into syms.traced (and
every module table), before owner/emit see it. Terminates (promotions only
grow, bounded by class count).
- gcinfer.render_final: --dump-gc now reads the authoritative is_gc_class
(structural + demand + the remaining @gc bridge), with the reason.
Effect: a class that escapes is inferred `gc` with no annotation — e.g. `Cache`
(rc.wo sans @gc) shows `gc (alias escape (demand))`; `Box` returned out of
`leak` is promoted and the program is valid. No false positives: employee's
Department/Employee stay owned; the 566 goldens + 14 test_diag unchanged.
Corpus: compile-fail/borrow-escape-return reclassified to run/ (prints 1) —
returning a borrowed class is now legal under demand promotion; the fixture
encoded pre-7b behavior.
Verified: woc-test 566/0 + test_diag 14/0; oop-e2e 79/0; employee 8/0;
log-watcher 7/0.
NOT in this slice: removing the `@gc` KEYWORD (parser rejection + rewriting the
RC/@gc golden + test_diag assertions + moving the inference injection into the
library so unit tests see it) — coupled to Phase 3, which deletes the RC
machinery those tests cover. The ring still needs Phase 3 to RUN (nullable
`?Node` gcref path).
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
GC-ness now comes from the inference pass, not only the annotation. A class is
traced if the structural SCC put it in `syms.traced`, OR (temporary bridge
until demand-promotion lands) it still carries `@gc`.
- Types.symbols gains a `traced : StringSet.t`; is_gc_class reads it (union'd
with the surviving @gc annotation). All symbols literals + both merges carry
the field.
- typecheck_all injects the classification once (Gcinfer.classify -> traced)
into the merged table AND every module table, before typecheck/owner/emit.
- emit.ml routes the class gc-flag and the union/drop decision through
is_gc_class instead of the raw `.is_gc`, so structurally-inferred gc classes
get the runtime flag. Field-kind derivation already routed through is_gc_class.
- gcinfer.traced_names exposes the traced set for injection.
Effect: docs/examples/gc-cycle now COMPILES with no annotation (the WO-E301
use-after-move at the ring-closing store is gone) — traced classes alias
freely. Bytecode is byte-identical to writing `@gc class Node`.
Verified: woc-test 566/0 (goldens unchanged — every current @gc class stays gc
via the annotation branch, and no golden has a structural-gc-non-annotated
class); oop-e2e 79/0 (gc corpus green).
Not in this slice: demand-promotion (the acyclic-aliased PriceCache case still
needs the @gc bridge) and @gc-in-source-as-error (Phase 2b); the ring RUNNING
(the RC runtime doesn't implement nullable-gcref `?Node` fields — Phase 3).
WO-W201 still fires on gc-cycle (retired in Phase 4).

Design-first deliverable for iteration 7b (no runtime/compiler code yet).
docs/examples/gc-cycle explains, by example, how pointers flow through the heap
and the collector's mark-sweep logic:
- types.wo: Node (self-referential ?Node -> inferred `gc`/traced) vs Segment
(acyclic -> `owned`, deterministically dropped)
- main.wo: ring_demo builds a->b->c->a and abandons it; owned_demo shows the
drop path with no collector
- README.md: the model (ownership frees the 99%, tracing only the cyclic/
aliased residue, inference decides), the 16-byte header rewrite (retire
rc+borrow -> 8-byte sweep-list link, colors in flag bits), where a traced
pointer lives (root via pc gc-mask / GCREF field / container), and the
tri-color incremental algorithm with the Yuasa deletion barrier. Two mermaid
step diagrams (heap+roots, collector cycle) + the owned contrast.
Grounded in the approved spec (2026-08-11-inferred-gc-mark-sweep-design.md) and
the real runtime structures (obj.h/wob.h: wo_hdr, WO_K_GCREF, arena, wo_obj_size).
Run status: honest — the sample does NOT build today; woc reports WO-E301
(use-after-move at the ring-closing store), which is exactly the aliasing that
"traced classes alias freely" unblocks under 7b. README records this.

Master now reflects only the current woc/wovm project. The Rust `wo` runtime
was the prior, abandoned architecture; it is fully independent of the woc/wovm
stack (dune + make, no Cargo dependency), so it lifts out cleanly. Recoverable
via git history.
Removed:
- crates/ (29 files) + Cargo.toml + Cargo.lock — the Rust runtime workspace
- prototypes/ — wo-rt-c (a stale duplicate of runtime/) + wo-db C++ ref
- justfile: the rt-c-demo / rt-c-bench recipes (drove prototypes/wo-rt-c)
- docs/plan/05..16 (11 Rust engineering plans) + docs/plan/done/ (4 Rust
Stage-2 done plans)
- docs/runtime/ (11): the old runtime overview + 7-phase DB design series +
async/fibers/gc/surreal concept essays
- docs/cm.md — legacy scratch note
Kept: compiler/, runtime/ (C VM), database/, the current-track docs
(stories, superpowers, plan/{oop-vm,compiler,exploration}, examples), the
discarded/learnings registers, and the syscall/postgres/assembly/c-runtime
studies. Follow-up commits fix the status board, project-structure doc, and
any dangling links to the removed docs.
Verified: woc + wovm still build; woc/wovm --version green.

The ##ui/.htmlx/LIVE track (plan 7) was removed as stale, so drop its dangling
references in 08-project-structure.md: the `ws, sub, htmlx, assets (plan 7)`
runtime/src line, the `06-ui-live` oop-vm contract entry, the `plan 7
UI/.htmlx/LIVE` server-track step, and `ui` in the build rule-of-thumb.

`client/` (wo-live.js live-patch runtime) never existed and was tied to the
removed plan 7 (##ui/.htmlx UI track). Dropped its tree entry, its proof-layer
section header + bullet, and its lifecycle-table mention (plans 4–7 -> 4–6,
http/ui -> http).
Left as-is: the Rust-track phase prose still names a `ui` crate scaffold and
plan-7 sequencing — that describes the maintained (non-advancing) Rust
roadmap, not a removed file.

Cleanup off master. None of this is referenced by the current woc/wovm
toolchain or the maintained Rust crates; it belongs to abandoned/scratch
state.
Removed:
- .planboard/ + .planboard.json — planboard task-tracking state for the
haxe-parity plan (tooling scratch)
- prompt.md — a stray one-line note about the old runtime's 13c task
- infra/ (deploy.sh, setup.sh, sync.sh) — deploy scripts for the old Rust
runtime (cargo build -p wo-rt, scp to writeonce.de, nginx/SSL/systemd)
- static/ + templates/ — the v1 blog's .htmlx frontend assets (svg/css +
about/article/home/layout templates); the UI track that used them was
already removed as stale
- content/ data/ wo-data/ — empty untracked v1 runtime dirs
Updated docs/08-project-structure.md: dropped the "v1 blog operating assets"
tree line and section. (cm.md keeps a historical mention of infra/sync.sh as
a legacy note — left as-is.)
Nothing kept references the removed paths (verified tree-wide; crates/rt hits
were `'static` lifetimes, not file reads).

The manifest pinned `[build] runtime = "../../../runtime/wovm"`, a repo-only
relative path that overrides woc's runtime resolution — so `woc <copied-dir>`
failed off-repo (e.g. an installed toolchain on a test server) with "runtime
binary not found".
- Drop the [build] section: the project no longer hardcodes a machine path, so
an installed `woc` self-locates `wovm` beside its own binary.
- The module justfile's `build` recipe now sets WO_RUNTIME=<repo>/runtime/wovm
so the in-repo build still uses the freshly built VM.
- Acceptance is unaffected (it compiles via `woc --emit` + an explicit $WOVM,
never the manifest [build] key).
Verified: just log-watcher::build OK; just log-watcher 7/0; and building a
copied tree with the installed-layout woc from an unrelated cwd self-locates
the sibling wovm and produces a runnable binary.

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/

- 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

stdlib, the embedded database, project/manifest layout, samples
- shipped-only by decision: every feature described compiles and runs
today; hello-world + switch snippet verified live before commit;
employee/log-watcher cited as the working acceptance samples
- unshipped roadmap (aggregates, HTTP service, concurrency/fibers,
cross-program attach + keypair auth, blue-green, @derive) kept in a
clearly-separated Roadmap section, plus named current limits (net
TCP-only, proc.run no timeout, no stdin/stdout, no FFI)
- note: root README.md is stale (documents the older Rust axum/REST
runtime, no mention of woc/wovm); left untouched, flagged for the
developer

- 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,
employee-accept 8/0
- 9b story + status board updated

- 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
rows added

- 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)

- Task 6 note: db fixtures live in existing corpus kinds; crash battery
proven at unit level; select fixtures wait on 9b's read surface
- board row updated
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- wo_row_update_field: encode new value, unique re-check against a
shadow BEFORE any mutation (violating update leaves the row
untouched, DB_ERR_UNIQUE), index entries moved old-hash -> new-hash,
old engine value freed; proven by test_table (unique refusal keeps
the row, released key becomes insertable)
- WAL UPDATE record: full-row re-log, replay = replace (remove +
re-create same id); prefix/suffix delta recorded as later
optimization; test_wal replays insert+update to the updated state
- builtins 62 DB_UPDATE_FIELD (cid,id,field,value) and 63 DB_DELETE
(cid,id), commit-before-ack like insert, WO_T_UNIQUE/WO_T_DB/WO_T_IO
mapping; dispatch range 61..63; loader arities; runner mirror
- plan Task 5 marked superseded-in-part with the recorded deviation:
the language surface (reads, queries, row views, delete statement)
is 9b's, where the comprehension design put it -- no interim brace-
select grammar to retire later
- gates: test_table 839/0, test_wal 102/0, 15 suites, oop-e2e 73/0

- docs/examples/employee-list: attaches to the running employee
program; modes list / report (byte-identical to A's own) /
staff <dept> / probe-write (registered read-only, insert must trap
access-denied, exit 4, A unchanged)
- the manifests ARE the design, written as a pair: A's [share] gains
listen = unix socket beside WO_DATA plus [[share.clients]] naming
B's public-key fingerprint with rights = "read"; B's
[connect.employee] carries A's ipc string, A's PINNED fingerprint,
and project = ../employee for compile-time shapes -- the connect
section's name is the code's namespace (employee.Employee)
- fingerprints are PASTE-HERE placeholders by design: keys generate
into WO_DATA at first boot (9d), tomls carry fingerprints only,
printed by --identity
- sample-first: compiles after 9/9b/9c/9d; README maps each mode to
the acceptance line it exists for; 9c/9d stories now name this
sample as their workload
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- 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
marked superseded-as-end-state; roadmap + board rows added
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- 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
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- 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

- 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

- 9b spec gains section 6 "Ownership, borrows, and GC across the
engine boundary": two one-way copy gates (no VM pointer enters a
row, everything a select returns is copied out), so the collector
never traces engine memory and the engine never touches refcounts
- row views are borrows WITHOUT a runtime net: rows share the VM's
field encoding but not its header, so no borrow word backs them --
the compile-time escape rule is load-bearing alone
- cursor stability settled: scans materialize their id list before
the body, row updates through the view stay legal (raise mode
updates an indexed column mid-scan and is the proving fixture),
insert/delete on a table with an open cursor is a new WO-E5xx
- GC-pause interaction recorded: collector runs between statements,
a long scan delays slices -- accepted, documented
- iteration-7b ordering constraint: GC inference must classify before
table-field validation, diagnostic names the inference reason --
noted in 7b story, iteration-9 plan constraints, 9b plan tasks
- stories 09/09b Info sections point at the analysis; 9b plan Tasks
3/5 carry the enforceable checkboxes (ASan boundary assertion)

- docs/examples/employee: Department/Employee @table classes with
@unique, [dept] and [dept, salary] indexes, ref/backlink pair;
modes seed/report/staff/raise/drop per the 9b spec section 6 —
written AHEAD of the features (sample-first, like log-watcher);
README states it does not compile on today's toolchain and links
the plans that compile toward it
- report mode is the GroupBy showcase: group-and-reduce projection
{headcount, avg, min, max} ordered by avg desc, whole-query sum
for payroll; staff proves both navigation directions + index probe;
drop proves delete restrict (trap asserted)
- engine directory decision (user, 2026-08-15): database/ is its own
top-level dir, statically linked into wovm — file structures updated
in the iteration-9 plan and the 9b plan
- gap found by writing the sample: iteration 9's subset lacks a
`delete` statement and restrict needs one — added to 9b plan Task 3
- 9b plan Task 6 notes the sample is pre-authored and authoritative
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- 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

- justfile: hello/pricing/pricing-demo/pricing-pg-demo/hello-demo
recipes removed with the examples they served (Rust-runtime demos);
rt-c-* prototype recipes and every gate recipe stay

- docs/examples/log-watcher/justfile carries build/accept/soak; the
root mounts it with `mod log-watcher`, so `just log-watcher` still
runs the acceptance (default recipe) and every doc reference stays
valid; `just log-watcher::build` / `::soak 60` reach the rest, and
plain `just build` works from inside the directory
- ROOT is source_directory()-based: inside a `mod`,
justfile_directory() names the ROOT justfile's directory and every
path would miss
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- a directory carrying wo.toml is a PROJECT: `woc .` inside it (or
`woc path/to/project` from anywhere) reads the manifest and produces
<target>/<name>, exactly what `woc build <dir> -o ...` produces
- schema is the one the sample already carried -- top-level name/
version/description, [runtime] wo (accepted, not yet enforced) --
plus a new [build] section: runtime (wovm to prepend) and target
(output dir, default "target"), both relative to the manifest's own
directory so the build is invocation-point independent
- unknown keys and sections are hard errors: a typo'd key silently
ignored would build the wrong thing
- directories WITHOUT wo.toml keep check-only semantics -- the corpus
is full of those; oop-e2e 71/0, woc-test 565/0, log-watcher 7/0
- sample's wo.toml gains the [build] section; target/ gitignored

- 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
