- language: `spawn Cls { fields }` expression (ctor semantics — fields
MOVE; result is the address); `actor M` parametric field type
(contextual like multi/map — actor stays a legal identifier); `send`
is a builtin free-fn name, not a keyword (shadowing rule applies)
- typing: M inferred from Cls's receive(msg: M); WO-E221 when receive
is missing, mis-armed, or M is not a class/record/union; send checks
addr is `actor M` and the message IS an M (silent when underivable);
ctor half of spawn delegates to the Ctor arm (completeness, ?T, E207)
- ownership: send's message TRANSFERS (sender's later use = WO-E301,
corpus-pinned); spawn's fields move via the ctor machinery; an
address is Copy
- emit: spawn lowers to ctor + LOADK receive's method index + BUILTIN
68; send is BUILTIN 69 with the message excluded from fresh-arg drops
(the runtime owns it now)
- runtime: wo_actor (moved-in instance, receive idx, growable FIFO
mailbox, one delivery fiber at a time); delivery reuses the fiber
context across messages and re-queues per message (fairness — an
actor never monopolizes); the runtime drops each message after its
receive returns; actor state/queued/in-flight messages are GC roots;
teardown drops everything (main-return reap included); loader knows
the two arities
- corpus: run/actor-echo (typed spawn/send, one-at-a-time delivery
interleaved with main by budget — output exact, ASan-clean),
compile-fail/spawn-no-receive (WO-E221), send-after-move (WO-E301)

- fiber states (RUNNABLE/PARKED/DONE), intrusive FIFO run queue,
wo_vm_spawn_fiber (calloc'd context, frame 0 set up like wo_vm_call)
- reduction budget: WO_REDUCTIONS (default 4000), checked at loop
BACK-EDGES AFTER the jump lands so the saved pc is the loop head —
a pre-instruction save at budget 1 re-executes the jump into the
same decrement and livelocks (found by reasoning, pinned by the
budget-1 test; deviation from the spec's three-site wording,
recorded in the yield macro's comment)
- FIBER_DONE: main returning ends the program and reaps every
remaining fiber through vm_unwind (drop maps run); a spawned fiber
ending frees silently; its return value is discarded by contract
- TRAPF: an uncaught trap in a spawned fiber kills that fiber ALONE
(stderr report, program lives); in main it stays the program's death
- WO_SYS_STOPPED reaps all fibers wherever it lands (main unlinked
from the queue and unwound if a spawned fiber caught the stop)
- vm_gc_roots walks the live fiber plus every queued one
- test_fiber (45 checks, ASan): EXACT round-robin interleave at budget
1 across three fibers pushing tags into one shared multi;
main-return reaps a spinning fiber holding an owned Big (ASan proves
the free); a DIV0 fiber dies alone, main answers 0
- full battery green: wovm-test, oop-e2e 89/0, woc-test, log-watcher

- wo_fiber = the interpreter state wo_vm held inline: register window,
frame stack, catch stack, caught-error slot; wo_vm keeps module,
runtime, the embedded fiber 0 (main) and the cur pointer every
interpreter access now reads through
- vm_gc_roots split into a per-fiber walker + the all-fibers caller
(one fiber today; the loop is where stage 1 T2 adds the rest)
- PURE refactor, no functional change to hide behind: full battery

(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

- 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)

- 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

their real owners (future migrations story, 9-series query surface)

(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

- 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->

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,

- 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

- emit_return's place test matched only bare Ident/Field/Index, so
`return "${p.content}"` (p a loop borrow) returned the part's own
string; the caller's eventual drop freed it under the container —
arena corruption surfacing two requests later (multipart slice)
- the return test now sees through Interp exactly as copy_place_text
does (is_borrowed_value_t, container reads excluded); bare
Ident/Field/Index behavior at return unchanged
- interp-borrowed-field fixture grows the return flavor (fn first),
50 iterations exact
- gates: oop-e2e 89/0 (ASan stage), 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

- 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

- copy_place_text matched only bare Ident/Field/Index, so a Text-typed
single-segment interpolation ("${r.method}", r a loop borrow) passed
the place's own register through a binding/assignment boundary — the
local aliased the row's field and its overwrite freed it
- release-build crash; invisible to ASan (in-arena free, no redzones)
- now asks is_borrowed_value_t && not is_container_read — exactly
drop_fresh_text's place test; Int segments (fresh int_to_text) and
container reads (already copies) stay uncopied as before
- pinned by tests/corpus/run/interp-borrowed-field (crashed both
runtimes before the fix, 50 iterations now exact)
- gates: woc-test 540/0, oop-e2e 89/0 (ASan stage included)

the web-framework branch; unmerged start = branch stacked on unreviewed

- 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

- 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

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

- 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

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.

The disclosed "move-on-push" gap detonated on iteration 16's route-table
pattern: `push(self.routes, r)` moved the Route into the container while the
`take r` parameter's scope-end DROP still fired — the container's own drop
plan (multi_free) then freed the element a second time. ASan: SEGV in
class_free during trap unwind; latent until now because pushed elements were
Texts, which copy at the boundary (2026-08-14).
owner.ml analyze_call: `push`'s value slot and `set`'s key/value slots now
TRANSFER an Owned, non-copy-stored place (record_move, exactly the take-arg
shape), so the pusher's drop disappears. Text/json.Value keep the copy-store
path (stores_by_copy) and the caller still drops the fresh copy. Traced (gc)
values remain exempt (tracing owns them). A user-declared push/set fn of the
same name wins, per the builtin shadowing rule.
Pinned by tests/corpus/run/container-owned-move (route table: interface-
typed field values pushed via take params, dispatched by ICALL, mixed with
Text pushes) — the exact iteration-16 shape, ASan-clean.

[deps] entries now resolve to fetched, locked checkouts and compile as
module roots.
- resolve_deps (driver): .wo-deps/<name>/ cache beside wo.toml, wo.lock
pinning name -> commit SHA. Cold+unlocked: clone at the manifest rev,
record HEAD. Cold+locked: clone and checkout the LOCKED sha — a moved tag
cannot change the build. Warm+locked: HEAD==lock -> zero network.
Divergence is WO-E106 "lock drift" naming both SHAs and pointing at
--update-deps; every git failure (missing binary, bad URL, bad rev,
missing locked commit) is WO-E106 naming the dep and step. Guard rails:
fetched dep must be a writeonce project; a dep with its own [deps] is
refused (flat-only); dep name colliding with a local module dir is
WO-E107. All git via the git binary (Sys.command; output reads through a
temp file) — no network code in the compiler. Full clone, not --depth 1
(a locked SHA must be reachable regardless of tag movement) — recorded
deviation from the plan's clone sketch.
- woc --update-deps <dir>: re-fetch at manifest revs, rewrite the lock.
- Multi-root compile: compile_image gains ~deps; app files first then deps
sorted by name; module_of_multi maps a dep file to `<name>` /
`<name>/<sub>`, so existing use/pub/collision machinery works across the
boundary unchanged. The app root's walk skips .wo-deps via the existing
dot-rule.
- Entry restriction: Emit.emit gains ?entry_ok (default true — test helpers
untouched); the driver excludes dep files, so a dependency's fn main is
never the entry.
Verified end to end against local file:// remotes: cold fetch + lock; `use
niceframework` + `use niceframework/strutil` build and run; offline rebuild
with the remote deleted; moved tag -> cold rebuild stays at the locked SHA;
--update-deps follows the tag and rewrites the lock; cache/lock drift,
transitive [deps], and name collision each produce their named diagnostic;
the dep's fn main (returning 99) never becomes the entry. woc-test 540/0;

The manifest grows [deps]: `name = { git = "...", rev = "..." }` — a
one-line inline table accepted ONLY under [deps] (a tiny scanner, not
split-on-comma: URLs may contain any character). git+rev both mandatory and
non-empty; duplicate dep names, unknown table keys, unquoted values, and
inline tables outside [deps] each keep/get a named diagnostic. Parse-only:
no fetch yet (Task 2).
Verified: well-formed parses; missing-rev / bare-value / outside-deps each
diagnose; woc-test 540/0.

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

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

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

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

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

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

- runtime/src/CODE-LOGIC.md: gc.c row describes the tri-color mark-sweep
(traced list, snapshot roots, Yuasa barrier, budgeted slices) instead of
RC + Bacon-Rajan; obj.c row gains the traced-list/may-gcref notes; main.c
row gains the post-exit pump.
- compiler/src/CODE-LOGIC.md: pipeline diagram gains gcinfer.ml between
types and owner; the owner-tables section drops rc sites and names the
inference pass as the source of GC-ness.

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.

added, WO-W201 retired.)

The compiler no longer emits reference-counting ops anywhere, and the format
reserves them. With Phase 3a's collector this completes the runtime half of
iteration 7b: spec success criteria 3 (no RC ops in any image, opcodes
reserved) and 6 (corpus ASan-clean) are met — `just oop-accept` is fully green.
- owner.ml: the rc machinery is deleted outright — rc_site/rc_op types, the
rcs table, fn_rcs/rc_groups/rc_escaped, record_rc, release_gc, gc_escape,
resolve_rc, and the clobber rule (its only consumer was elision). The
`push`-of-a-gc-value RC_INC special case is gone (the bug class cannot recur
without RC). Drop tables (owned + LGc kinds) are untouched — the gc mask is
what feeds the collector's root maps.
- emit.ml: emit_rc, the v_rc view, the escape-acquire anchor, and every
caller deleted; assignment displacing a traced value emits nothing (the VM's
store barrier owns it); scope-ended LGc handles clear their gc-mask bit so
root maps stay precise.
- .wob v4: WOB_VERSION 3 -> 4 in wob.h + emit.ml + disasm.ml + the runner's
loader battery; opcodes 27-28 removed from the enum/jump table/interpreter
and REJECTED by the loader like any unknown opcode.
- dump.ml: the == RC == owner-dump section is gone; 6 goldens re-blessed
(owner dumps lose the section, elision.wo's bc dump loses its RC ops).
- runner.ml: rc-table/ELIDED assertions deleted; the elision test now asserts
the WHOLE image contains no RC op; the table-contract sweep asserts rc ops
never appear.
- test_unwind.c: the rc-opcodes test becomes two — the loader rejects reserved
opcode 27, and an abandoned traced instance is freed by rt_destroy
(ASan-proven).
Verified: woc-test 540/0 + test_diag 14/0; runtime test + test-iso all suites
ASan/UBSan (test_unwind 12/0); cli_smoke; oop-e2e 79/0 (v4 images end to end);

Reference counting and Bacon-Rajan trial deletion are gone from the runtime.
Traced (inferred-gc) objects now die only by the collector; owned values keep
deterministic drops exactly as before.
- wo_hdr: rc retired; borrow and the freed 4 bytes become a union — non-traced
values keep the borrow word, traced objects use the 8 bytes as the intrusive
sweep-list link. Header stays exactly 16 bytes. WHITE is now the all-zero
color (allocations born white by memset); WO_F_BUF retired.
- gc.c rewritten: snapshot-at-beginning tri-color mark-sweep. Roots (frames'
gc+owned masks) shaded atomically at cycle start; Yuasa deletion barrier
shades the OLD target of every gcref edge deleted while marking (SETF
overwrites + every owned-death path, which all funnel through wo_drop_kind's
GCREF case); allocations mid-cycle born black. Mark AND sweep budgeted
(WO_GC_BUDGET objects/slice), sweep resumes via a cursor; gray-worklist OOM
degrades to a blacken-all cycle (frees nothing, never wrong). Owned interiors
walked eagerly (single-owner trees), pruned by a per-class may-gcref bit
computed at rt_init (fixpoint over kinds + v2 field_class/field_elem;
conservative when metadata is absent).
- vm.c: safepoints at NEW (the heap-goal trigger), CALL, and backward JMP;
root scan follows vm_unwind's governing-pc convention. Unwind's gc-mask
branch just nulls the register. RC_INC/RC_DEC are accepted as no-ops until
the emitter stops producing them (next commit) — which also deletes the old
RC_DEC-on-nil trap that broke `?Node` gcref field stores.
- main.c pump: post-exit, a rootless cycle frees everything unreachable in
budgeted slices; the trace line moved into wo_gc_slice (one format for pump
and in-program slices). rt_destroy frees traced remnants (trap paths, tests).
- WO_GC_GOAL joins WO_GC_BUDGET/WO_GC_TRACE as an rt-owned knob (default 256
KiB; a tiny goal forces mid-program cycles for testing).
- tests: test_cycle.c rewritten (abandoned cycle freed, rooted cycle survives,
slices bounded, cycle-through-multi, repeated-cycle leak-freedom, and the
spec's load-bearing DELETION-BARRIER test: an object hidden behind a black
object mid-mark must survive). test_rc.c re-pinned to owned drops + the
owned/traced boundary; test_obj.c asserts tracked-white-linked instead of
rc=1.
Verified: make test + test-iso (all suites, ASan/UBSan; test_cycle 42/0,
test_rc 14/0) + cli_smoke; oop-e2e 79/0 (gc corpus traces unchanged: the new
slice math reproduces steps=1/freed=2 and steps=2/freed=4); employee 8/0;
log-watcher 7/0. THE RING RUNS: docs/examples/gc-cycle prints
`ring a -> b -> c -> a`, is reclaimed post-exit (freed=3 remaining=0), is ASan
clean, and survives an in-program cycle while rooted (WO_GC_GOAL=64: mid-run
slice frees 0, post-exit frees 3).

`@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.

Wire Gcinfer.infer into runner.ml's owner_str/emit_str so the unit tests
classify GC-ness identically to the driver (prerequisite for removing @gc: its
tests read the golden .wo through the library).
That exposed owner-err/borrow-escape.wo, which tested WO-E304 on *class*
escapes — now legally demand-promoted. Retargeted it to CONTAINER (`multi Text`)
escapes, which are owned and never promoted, so it still exercises the three
WO-E304 shapes (stored-in-field, returned, moved-to-take). Assertion positions
+ golden re-blessed.
Verified: woc-test 566/0, test_diag 14/0, oop-e2e 79/0.

The escape hook promoted the borrow-root local's class, so `return h.box`
over-promoted the container `Holder` alongside `Box`. Now `owner.ml`'s
`transfer` passes the escaping place's type (`place_ty p`) as `~promote_class`,
so only the value that actually escapes is promoted.
- escape: takes ~promote_class; records it in collect mode, else reports WO-E304.
- borrow-escape.wo now promotes only Box (was Box + Holder); rc.wo sans @gc
still promotes Cache.
Verified: woc-test 566/0, test_diag 14/0, oop-e2e 79/0.
