- rename the two libraries: writeonce-framework -> writeonce-serve
(`use serve`), wo-html -> writeonce-view (`use view`). Names say the
ROLE now; every sample, script, gate and live doc follows
- stories/specs/plans keep the old names: they are dated records, and
both library READMEs carry a "renamed 2026-08-25" note
- serve/http/files.wo: StaticFiles { dir, max_bytes } — traversal
refused not normalised, extension content types, attachment
disposition for archives. Lifted out of the shop, which had said in
a comment that it belonged in the framework
- shop drops its private copy and mounts the framework's
- site: /dl/*path over $WO_DIST (default ./dist), 16 MiB ceiling
- /install gains supported systems — Linux x86-64, glibc >= 2.38,
not musl — read off `file` and the binaries' GLIBC_ symbol
versions, not off a wish list; plus GitHub release as primary,
/dl as mirror, and the sha256 verify step
- site-accept: 17 -> 21 checks (supported systems, gzip download with
a binary-safe probe, checksum, /dl traversal 404)
Verified on 192.168.0.165: the real 960,820-byte tarball downloads
as application/gzip and its sha256 matches the published digest.
Gates: oop-accept MET, site 21/0, web-app 46/0, fibers 10/0,
db-actor 8/0; shop rebuilt and its /assets served by the framework.

- 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/

- 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.

- 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

- 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)

- 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.

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

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

- docs/00-status.md: NEXT PLAN is now iteration 5's strictness half (?T forced
handling, pub(read) writes, using, #if) plus an ASan run over the workload;
iterations 6 and 7 marked landed; a "Landed 2026-08-14" section records what
actually shipped, and a new known-gaps block records what did not — lenient
optionals, unenforced pub(read), the borrowed-Text-into-container hazard,
json's Bool/float limits, net fd lifetime, no ASan over the workload, and no
corpus fixtures for the new surface (by direction: the sample is the test)
- runtime/src/CODE-LOGIC.md: file map, the loader-is-the-only-validator and
traps-never-leak invariants, the catch stack, records the VM fills but cannot
name, class metadata + json, program mode, and where to look when it breaks
- compiler/src/CODE-LOGIC.md: the pipeline, why there are two type derivers and
the stay-silent-when-underivable rule, how contextual values get a
destination, the node-id/label contract between owner.ml and emit.ml, the
four kinds of qualified call, predeclared records, the constant-interning
trap, register discipline, and how to verify a change
