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

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

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

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

- docs/examples/chat: registry (call consumer) / room / reader+writer
actor pair per connection over ws_accept + wsframe; presence,
broadcast, cross-room isolation, mailbox-full = drop-from-room;
reader tail sends hardened (a full writer no longer orphans the fd)
- RUNTIME SEMANTICS CHANGE (the drain): SIGTERM no longer kills parked
fibers from outside — the plane WAKES them and each wait RESOLVES
(deadline'd waits answer their timeout result, sleeps return early,
plain waits answer WO_SYS_STOPPED and unwind THAT fiber alone; main's
STOPPED still ends the program). Workers keep adopting their inboxes
after stop until eng_shutdown. This is what lets a program drain:
chat's close frames now reach clients (byte-verified 0x88), then
main returns and the reap runs
- also: SIGPIPE ignored process-wide (EPIPE trap instead of death);
two-phase engine teardown (real drops while arenas+routing live,
settle passes for routed frees) — fixes the registry-map leak and
the drain UAF ASan found
- gate scripts/chat-accept.sh + just chat: handshake independently
verified, functional matrix on BOTH backends, 1k-hot-room soak
(1000/1000 in ~35ms), drain close-frames, SIGTERM exit 0, ASan leg
clean. OPEN: soak-fds check (18 fds settle slower than the window)
+ full battery after the semantics change — NOT yet run
- committed for manual testing at the user's request
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- monitor(watched, observer, msg): registration lives on the watched
actor's home thread (kind-7 envelope cross-shard); actor_die walks
the list; already-dead fires NOW; the notice msg moves; a full
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
generation-counter idiom is pinned by run/timer-generation
- runtime_notify: one runtime-sourced delivery path (notices, timers) —
reserve-or-drop, cross-shard via kind-0 envelopes
- compiler: monitor typed as a bespoke free fn (notice typed against
the OBSERVER's mailbox — the three-argument deviation, disclosed);
time.after as a stdlib row whose msg arg is EXEMPT from the module-
call fresh-arg drop (it moves — the double-own bug the timer fixture
caught); owner move slots for both
- corpus: run/monitor-death (trap-death + already-dead notices),
run/timer-delivery (armed + immediate), run/timer-generation
- teardown drops undelivered notices and unfired timers; battery 13/13
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- parse.wo: ANY Transfer-Encoding header is 400-and-close (RFC 9112
§6.1) — silently treating chunked as body-less was the smuggling
door the dup-CL fix left open
- net.listen/listen_unix backlog 64 -> 1024: the soak's connect bursts
overflowed the kernel accept queue and BLACK-HOLED clients (three-way
handshake done, server never sees the conn — 35-70 stuck per run,
fully reproduced then gone at 1024; kernel clamps via somaxconn)
- web-app gate grows to 46 checks: TE-reject; the 1k soak — 500 real
conns all served + 500 idle conns all evicted, server fds home
(45 -> 45), RSS 24MB, healthy after
- battery green (site restart + fibers-TSan legs flaked under parallel
battery load, both clean serially — the standing flake pair)
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- runtime ids 91-95: net.read_dl/accept_dl/write_dl (per-call deadline,
nil/false = the EXPECTED timeout; ms<=0 = old behavior bit for bit),
net.listen_unix (unlink-before-bind, O_NONBLOCK on the listener —
probe-found: accept4's flag covers accepted sockets only), net.peer
- plane: one-op-per-park stays law — deadlines ride one per-shard
TIMEOUT tick (sentinel user_data) + post-CQE expiry sweep +
POLL_REMOVE tombstone; epoll's deadline scan grew the fd-park case;
fibers POOL instead of freeing mid-run (stale-CQE UAF); plain parks
zero park_deadline (no stale sleep deadlines)
- probe: all five seams verified on BOTH WO_IO backends (timeout
timing exact, peer round-trip, unix rebind)
- framework: parse_request grows first_ms/read_ms; serve_conn — the
keep-alive loop with deadlines where parked idle conns are LEGAL
(close-when-idle RETIRED); App.handle_conn exposes it; plain serve()
unchanged for simple apps
- web-app: app-owned accept_dl loop + ConnWorker actor per connection
(each builds its own App; cross-shard placement rides the DB actor);
WA_IDLE_MS knob; gate grows to 41 checks — two slow requests served
in PARALLEL, stalled client evicted at the idle deadline, slow-loris
torn at the read deadline (400)
- docs: story 35 -> done with banner; SQE/CQE design spec LANDED (was
the review doc); ledger rows (timeouts/unix/keep-alive/peer), graph
(NETSEAM cleared, KEEPAL done), builtin-surface rows, runtime
CODE-LOGIC section, board entry
- battery 13/13 fresh-built

- progress ledger with commit ids + the two en-route compiler/runtime
fixes; pending list carries each task's remaining shape and the
disclosed deviations (scalar replies v1, three-argument monitor)
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- runtime: mailbox slots grow caller metadata (wo_msg), call parks on
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
- actor death is real now: a receive trapping uncaught marks the actor
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)
- corpus: run/call-echo (park + ordered replies), run/call-dead-trap
(mid-call + to-dead, both catchable), compile-fail/call-void-receive,
compile-fail/call-reply-disagree; cross-shard call proof rides the
chat gate next

- docs/examples/wo-html: library dep — esc(), element builders,
Tailwind-style utility sheet as one static string, page() shell;
self-contained responses, no CDN/JS/build step
- docs/examples/site: the language tutorial served by the language —
9 seeded chapters in a @table (hello/values+bitwise/containers/
classes/optionals+traps/tables/actors/deps/serving), server-rendered
via wo-html, seed-if-empty so WAL restarts keep admin edits
- routes: / index, /ch/:slug (styled 404), /health, POST /admin/ch/
:slug (bearer handler-side — mechanism framework's, policy app's;
form-encoded title/body update by assignment, 302 back)
- chapter code samples use the lexer's \$ escape to show ${...}
literally; .. never straddles newlines (accumulator style)
- gate: scripts/site-accept.sh + just site — TWO file:// dep remotes,
11 checks incl. authed-edit-survives-restart; /health polling, no
boot-race sleep
- README: run + nginx sketch for writeonce.de; CODE-LOGIC beside code
- full battery 13/13 (site gate included)

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

- one iteration by directive 2026-08-23: call() parks with typed reply
(envelope kinds 5/6 over the DB-RPC park), mailbox cap 1024 +
WO_T_ACTOR fail-fast, monitor(addr, msg) one-way, time.after
one-shot no-cancel
- story 34 resolved: C builtins sha1/sha256/hmac_sha256 over Bytes,
RFC vectors gated
- WS pure .wo: handler-owned upgrade (ws_accept + hijack sentinel),
frame codec over Bytes via 36's bitwise, two actors per connection
(sole-reader + sole-writer)
- chat sample: registry + room actors, python raw-RFC6455 gate —
cross-shard functional, 1k soak, SIGTERM drain, battery unchanged
- status PROPOSED — awaiting review before the plan
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- story 34: premise fixed — iteration 36 landed bitwise/hex, digests
and HMAC now expressible in pure .wo; C-builtin vs pure-.wo is the
story's brainstorm call, not an impossibility
- dependency graph: crypto gate names story 34; net-seam gate names
story 35; radix gate corrected — 22 benched the DB, router scan
still unmeasured, perf-targets entry first
- framework README ledger: timeouts/unix/peer rows point at story 35;
ETag row at story 34; path-matching row repointed off iteration 22
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- brings time.ticks builtin (id 84), bench sample + campaign driver
(scripts/db-bench.py), just db-bench/db-bench-quick recipes, first
baseline recorded, story 22 to done/, postgres study cards
- conflicts resolved: board in-progress table (iteration 36 +
framework rows kept, db-bench row now "22 landed"; dangling order
anchor repointed); story 36 moved back to in-progress/ (dir-rename
inference dragged it to done/ — 36 still awaits the manual pass)

"fibers (11)" — now "arc landed 2026-08-21, parked until own slice";
ledger date 2026-08-22
- dependency graph: crypto-fork gate note updated — bitwise + hex
landed with iteration 36, digests expressible in pure .wo; story
34's brainstorm still owns the pure-.wo vs C-builtin call
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- owns the framework ledger's three seam rows; deadlines compose with
the arc's park plane (POLL_ADD+TIMEOUT fork recorded); framework
knobs explicitly out of scope; stalled-client soak in acceptance
- board + table rows (held seqs bumped); pairs naturally with 24
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- SHA-1 (WS-handshake hard req, RFC 6455 worked example as acceptance),
SHA-256, HMAC-SHA256 over Bytes; hand-rolled C per doctrine, FIPS/RFC
vector fixtures; four forks recorded (namespace, shape, source, file)
- gates chain item 24; digest floor for held 21 + ETag row; 24's
dependency note repointed; board + table rows (held seqs bumped)
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- file path IS the wal; dir form byte-identical; one fork (nonexistent
path semantics) leaning recorded; off-chain, driver-only
- board + story table rows (held tail seqs bumped)

- engine: wo_idx_probe answers single-column equality from the index
hash buckets (idx_hash_key1 reproduces idx_hash bit for bit; verify
compares exactly as the slab walk did, so results identical);
composite indexes keep the walk; both executors wired (local + DB
actor RPC)
- compiler: probe_key_of_where lowers "var.col == key" on an indexed
column to DB_PROBE; all where guards still run (guard stays the
final arbiter); keys = ident/int-literal only; Float/Bytes excluded
(engine raw-eq narrower than VM float-eq)
- measured: reads 1.3k -> 1.3M ops/s, p50 600us -> 1us (~x850);
query x830; mixread 1.3k -> 89k s1, 21 -> ~1.9k sN
- gate policy moved into the driver (tolerance_for: refresh-proof);
latency floors max(4x,100us); quick mode skips poll-bound mix
floors; both tolerance classes proven to bite
- proof: test_table wo_idx_probe suite (RED first), corpus
query-index-probe 105/0, full battery green, TSan clean, two
campaigns pass the refreshed baseline
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- constraints-and-grammar: gram.y PK/FK productions, pg_constraint,
RI trigger semantics; writeonce direction — @key as unique alias
(id stays THE key), ref actions (@on_delete), backlink-implies-index
(improves on postgres' not-auto-created FK index)
- indexing-and-point-lookup: AM roster + algorithms (Lehman-Yao,
linear hashing), TID = row address; writeonce gap — probe walks
slabs while idx_bucket exists; O(1) slice direction, non-goals
- card index updated; Rust-era plan-10/11/12 links unlinked (rot)
- docs/guides/database-developer-subagent.md: format, paste-ready
agent definition (doctrine/file map/gates), verification, division
of labor

- bench/baseline.json: 74 metrics from the first full campaign;
tolerances tuned by a two-run repeatability check (mix* 50%,
read/query 35%, rest 15% — rationale in _config)
- gate bites: --check mode; doctored copy fails, both real runs 74/0
- headline: durable seed 4.5k/s vs ram 297k/s (23's case); reads
O(table) at ~1.5k/s; mixread 1280 vs 21 ops/s single-vs-multi
(the arc's price); msgrate 13.4M vs 2.45M (mutex-inbox number)
- arc delta recorded in story 8; findings in sample README
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Mixer actors: 90/10 read/write, per-actor histograms merged through
the store itself (Hist rows) — exact aggregate percentiles
- msgrate: one-way flood at a worker-placed sink; measured 15.3M
msgs/s same-heap vs 2.06M cross-shard — the mutex-inbox number
- finding: point lookups are O(table) (probe walks all slabs), so
read-heavy mix is quadratic in store size — all-mode calibrated to
N/10 mix ops; the number 22 exists to publish
- TSan clean both shard counts (setarch -R, fibers-gate pattern)
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- seed/read/query/write/wal/verify/verify-acked + all (one-process
campaign: RAM store dies with the process)
- per-op time.ticks, 1us-bucket histogram percentiles (reservoir
deviation: no element-write/sort in language; better tail anyway)
- Meta expectation rows ride the same WAL verify checks
- finding: hand-built multi<TableClass> SEGVs on drop (elems classed
OWNED, refs are scalar ids) — worked around, recorded
- finding: reads ~1.6k/s p50 595us vs 287k/s inserts — probe walks
all slabs; the number 22 exists to surface

- worker DB builtins marshal to shard 0: requester-side slot encode
(VM heaps never read cross-shard), owner executes serialized in
adopt, reply unparks via new WO_PARK_INBOX park + envelope 3/4
- engine gains thread-agnostic slot entry points (insert_slots,
update_field_slot, val_encode/clone, wo_db_exec_req); traps and
messages byte-identical to the local path
- main.c: engine + replay boot BEFORE shards spawn; workers assert
rt.db/rt.wal NULL; busy shard adopts inbox once per slice
- latent stage-1 bug fixed: shared io_uring params static raced by
lazy worker init lost park wakes (~1/20 hangs); params per-vm,
short submit now fails loud
- new sample docs/examples/db-actor + just db-actor gate 8/0 (multi

ASan+TSan 6/6; full battery green

ack-after-owner-fsync, workers WAL-free + replay-before-serve,
no torn reads under TSan corpus); arc plan stage 3 carries them
- refine/32-wal-checkpoint.md: snapshot + truncate, bounded replay,

- Float full stack: literals (fraction/exponent; `0..10` still a range), f64
opcodes 34-41, @table column, WAL bit-exact replay, json fractions in and
shortest-round-trip out. IEEE-quiet — FDIV never traps where DIV does.
- Bytes: a wo_str with its own class id, so alloc/free/copy are shared but no
Text builtin accepts one; len/at/slice/eq/concat, base64 both ways, json
boundary as base64; TEXT_COPY preserves the kind.
- No implicit Int/Float mixing (WO-E201 in the typechecker, not the emitter,
which picks the opcode from one side and would misread the other).
- One IEEE deviation: float_cmp total order (NaN last, -0.0 == +0.0) for
indexes and order-by, keys canonicalized to match. `?Float` nil is a
reserved quiet NaN — the zero word is +0.0, WO_NIL_SCALAR's bits are -2.0.
- Renderer prefers fixed over exponential in 1e-6..1e21: pure shortest makes
a price of 900.0 read `9e+02`. One renderer for interp/json/float_to_text.
- Fixed en route: lexer double-counted the leading digit; is_scalar_shaped
took Float/Bytes as Int-shaped; Bytes ownership needed a shared heap-scalar
predicate or temps never dropped; order-by bit-compared negatives backwards.
- Iteration 17: `kind = "library"` (absent = program; bad value = WO-E109),
entry-less check mode retiring the `--emit` workaround, Go's `internal/` as
WO-E108 at the consumer's `use`. Driver-only; VM/.wob/GC untouched.
- Framework reorg: internal/{parse,serve}.wo; http/form.wo split out to keep
media_type/form_values public (parse.wo had grown public surface).
- Docs: link audit (97 -> 88 broken, conflict markers resolved, 2 duplicate
stories removed), 00-code-review verified 26/27, iterations re-sequenced.
- Also carries the pre-staged pub(read)/using/#if work from the index.
- Gates: corpus 103/0, test_wal 156/0, web-app 26/0, oop-accept ALL MET.

- developer directive: pending iteration IDs now ARE the priority order;
LANDED iterations keep historical numbers (code comments and commit
history cite them — records, not a queue); 8/11 (the half-landed
arc), 17 (parked, artifacts on a branch), 18 (next, artifacts named)
also frozen
- mapping (recorded in 00-story): 19<-20 Float+Bytes, 20<-9c attach,
21<-9d keypair, 22<-9e benchmarks, 23<-9f io_uring WAL, 24<-19 chat,
25<-10 services, 26<-12 blue-green, 27<-9g query corpus,
28<-14 skillhost, 29<-13 metaprogramming
- 11 story files renamed; every doc reference re-numbered (word-boundary
sweep for the lettered 9x ids, phrase-level for numeric ones); the
iterations table rewritten with Seq == priority and "(was N)" notes;
story-scoped link check: zero broken
- merge-recovery folded in: the partial master merge had dropped the
chat story, the fibers exploration note, the arc spec+plan, the
framework-v2 plan, and the iteration-17 spec+plan — all restored from
their branches and renumbered consistently

- brainstorm settled four forks: Float FULL STACK in one iteration
(literal, IEEE f64 VM ops via u64 bitcast, @table column + WAL slot,
json fidelity — json.c's own comment names the hole: fractions are
malformed because "the language has no [float]"); IEEE-754 QUIET
semantics (division never traps, NaN flows; Int keeps DIV0; no
implicit mixing — float(i)/trunc(f) bridges); BYTES ships alongside
(binary carrier: multipart files, WS frames for 19, crypto digests;
Text goes back to meaning text); iteration 20 + spec before code
(.wob/WAL version bump earns a written spec)
- the rest of the missing-type survey recorded with reasons: Result/
Option expressible today (?T + payload unions), tuples covered by
records + doctrine, Decimal stays cents-until-a-workload, Char/
Unicode its own future story, Set/ADTs parked post-12, scalar
newtypes need the rejected `abstract`
- one indexed-storage deviation from raw IEEE spec'd loudly: a Float
index needs a total order — NaN sorts last
- board row, story-table row (seq 26), graph node (9+16 -> 20 -> 19;

- docs/examples/fibers: part 1 is TIMING-FREE and byte-exact — main
sends three messages then burns reductions; each budget expiry hands
the Counter actor exactly one delivery (cooperative mechanics,
preemptive fairness, BEAM's shape); part 2 parks a Sleeper actor
mid-receive on the I/O plane while main keeps ticking — the wake
lands between ticks, proving a sleeping fiber blocks nobody
- the missing "sleeper: up" on the first run was main-return-reap
working as specced (main ended before the deadline); the demo's
window widened so the wake is observable
- scripts/fibers-accept.sh + `just fibers` (8 checks): build, part-1
exact + part-2 ordering invariants on auto/uring/epoll backends,
and an ASan-runtime rebuild+run
- README points at the doctrine writeup (exploration/fibers)

- done/ (11): 1, 2, 3, 4, 6, 7, 7b, 9, 9b, 15, 16 — landed iterations
(9/9b remainders live in the post-12 drain list, not in the files)
- refine/ (8): 9c, 9d, 9e, 9f, 9g, 11, 13, 14 — everything marked
"no spec yet / brainstorm before planning"
- root keeps: 00-story (index), 05 (partial, plan 8 open), 8/10/12
(specs or plans exist), 17 (parked, spec+plan approved), 18 (next)
- every cross-reference re-pathed and VERIFIED resolving: board, specs,
plans, employee-list README, story table, intra-story links (moved
files' relative links deepened one level; done/7b's 9e pointer now
crosses to refine/)
- pre-existing dead link noted, not touched: refine/11-fibers.md points
at docs/plan/exploration/fibers/00-fibers.md which does not exist
(predates the move)

- 00-story.md iterations table rows reordered into implementation order
with a Seq column; # stays an immutable ID (files never renumber —
every board/spec/plan references by number)
- order: 1-7b, 9, 9b, 15, 16 (landed, landing order) -> 18 NEXT (spec
approved) -> 9c -> 9d -> 9e -> 8 -> 9f -> 11 -> 10 -> 12 -> 9g -> 14
-> 13; 17 parked row at the end, slots anywhere after 16 on directive
- story note + board implementation-order list synced (18 inserted as
item 2 after the parked-17 note; 9g now explicitly before 14; list
renumbered)
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- re-analyzed every story/spec/plan markdown for dependency statements
- added: iteration 17's OUTGOING edge (framework internal/ reorg + check
mode, WO-E108/E109 reserved); 1-6 foundation anchor; 9b -> 10 ("service
blocks want query results"); 14's gap fan-out node; post-12 parked
drain cluster with dashed scope-directive edges (13 + drain are
directive-held, not technically blocked)
- new graph 2: the concurrency chain — 8/9f/11 and EVERYTHING they gate:
keep-alive parking retirement, h2c, body/response streaming + commit
point, cancellation, pub/sub+WS, 9c's rejected async-statement
alternative, schedulable idle timeouts, fiber jobs (+18),
cancellation->rollback (+18+cancel)
- graph 3 notes 9d's keypair crypto is its own C impl, neither waits for
nor feeds the crypto-fork gate; storage-integration rows point at
their real owners (future migrations story, 9-series query surface)

- 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
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
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.

Board row 16 -> landed (web-app 14/0), pending row removed; story header
records the landing + the two as-built discoveries (idle-keep-alive
starvation policy; the two compiler gaps the chain exposed and fixed);
README gains the framework+web-app sample entry; plan checkboxes ticked.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- docs/examples/web-app: Product (@unique name, backlink orders) / Order
(ref Product) as @table classes; handlers as Handler classes —
ListProducts (ordered query -> JSON array), ShowProduct (unique-index
probe, 404), CreateProduct (checked json.decode -> 400; @unique trap ->
409), CreateOrder (FK insert), DeleteProduct (FK restrict trap -> 409);
Auth middleware reads WA_TOKEN. Entry validates port + token honestly.
- The [deps] KEY is the module name `use` imports: hyphens are not
identifier characters, so the app keys the dep `framework` while the
repository keeps its long name (recorded in the manifest comment).
- driver fix (real gap the chain exposed): a dependency's INTERNAL `use`
paths are written against its own root (`use http` inside the framework)
but compile under `<depname>/...` — compile_image now prefixes dep files'
use paths with the dep name (stdlib namespaces stay bare; a path already
starting with the dep name is untouched).
Verified end to end through the full chain (temp git remote of the
framework, file:// substituted, fetch -> lock -> build -> serve): 401
without the token; [] empty list; 201 create; 409 duplicate (@unique);
400 malformed json; list/show payloads exact; 404 unknown product; 201
order; 409 delete-while-referenced (FK restrict) with the server still
serving; SIGTERM clean; the product survives a process restart (WAL
replay). Gates: woc-test 540/0, oop-e2e 88/0, deps-accept 8/0.

- 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.

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

5 tasks, words-only per house rule, each with its verify step: (1) manifest

(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;
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;

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

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;
log-watcher 7/0; employee 8/0; gc-cycle ring prints + reclaims.

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).

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).
