- 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

- 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)

- 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

- 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)

- 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

- five-property map in marker doc: atomicity/durability/recovery
proven or held (18); concurrency control = stage 3's property;
space reclamation RAM done (slot reuse), disk = new story 32
- story 08: three stage-3 criteria (one commit per write RPC +
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,
crash-during-checkpoint safe; four forks; after 23
- chain now stage 3 -> 22 -> 31 -> 24 -> 23 -> 32 in all 10 docs;
boards + seq bumps synced

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

- done/ (11): 1, 2, 3, 4, 6, 7, 7b, 9, 9b, 15, 16 — landed iterations

- refine/ (8): 9c, 9d, 9e, 9f, 9g, 11, 13, 14 — everything marked

(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

- 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)

approved) -> 9c -> 9d -> 9e -> 8 -> 9f -> 11 -> 10 -> 12 -> 9g -> 14

- 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

- 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,

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

- 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

- 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

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

.wo-deps (gitignored) + wo.lock (committed); plan checkboxes all ticked.

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 +

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.)

- 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)
