- compiler: `insert Class { ... }` is a typed Ast.Insert in statement
AND expression position, sharing the ctor literal's field grammar;
typechecked with the ctor's omittable rule; result = the row id (Int)
- owner pass: the engine copies at the row API, so an insert BORROWS
its field values -- no transfer, no E304; node is trap-capable and
carries a live-mask drop entry like DbStub did
- emit: builtin 61 window = class-id const + one slot per DECLARED
field in declaration order; omitted defaults emitted, omitted ?scalar
gets WO_NIL_SCALAR, other omitted optionals the zero word; fresh
argument values reaped after (the push/set copy semantics)
- runtime: database/src/db.c executes via the choke-point row API;
rt.db/rt.wal opaque handles on wo_rt; WO_DATA=<dir> = replay
<dir>/shard-0.wal at boot + commit-before-ack per statement (the
builtin's return IS the ack until iteration 8 ticks); failed commit
un-applies the row and traps WO_T_IO; loader validates the class-id
slot (variable window documented in wob.h + format doc)
- the promised diff: trap/pricing-set-price-db-stub is now
run/pricing-set-price-insert printing engine-allocated ids;
durability smoke prints 1,2 then 3,4 across two WO_DATA runs
- old "bare insert is an Ident" unit test rewritten to the new
contract; runner's loader mirror accepts id 61; goldens re-blessed

wovm-test green, log-watcher 7/0

- owner.ml: `oclass_of` called `Text` a builtin scalar, so it was Copy and NO
Text local was ever dropped — that, not the missing stdlib table, was the
leak. Text is now Owned, which forces an answer for what it does at an
ownership boundary, and the answer is uniform: it is COPIED. Into a
container (push/set/`m[i] = v`, already true), into a field (SETF), out of a
function (return), into a binding (`let s = other`), and into a loop cursor.
The source keeps its value; a freshly built Text stays the caller's and is
dropped at the site
- owner.ml: resolve_callee answers for three shapes it never knew — reserved
stdlib members, builtins, and a class's `static` members — so their results
get a type, an owner and a drop
- vm/builtin: WO_B_TEXT_COPY, the one new builtin the rule needs; SETF copies a
TEXT field in; emit copies a Text read out of a container, bound from a
place, returned from a place, or loaded into a cursor, and drops a freshly
built one after a copying store
- sysio.c: fs.read_all/net.read allocated their cap then relabelled the buffer
with the short length — but wo_str_free sizes a block by its len (no size
headers, obj.h), so a 1 MiB buffer wearing a 30-byte length went onto a
32-byte free list and never came back. They copy out at the true size now
- two regressions the corpus caught, fixed in the same pass: a @gc value read
out of a container is a plain borrow, not an rc-counted alias; and push's @gc
escape is keyed on "push is not a user-declared fn" rather than "the callee
did not resolve", which stopped being true once builtins resolved
- docs: Task 1 closed in the executable plan with its before/after numbers, and
the status board's item 1 records the deeper root cause

Completes plan 2 Tasks 7-8. owner.ml: mutable-value-semantics flow analysis
producing the four plan-3 emitter tables (moves, drops incl. LIVE-MASK for trap
unwinding, rc with elision, residual borrow sites) plus WO-E301-304 two-site
diagnostics. Alias questions run over canonicalized places, so a double-mut
reached through let-bound aliases lands in the residual table like the direct
form; dump.ml's contract notes the emitter must coalesce guards per operand.
main.ml: directory discovery, cross-file programs (symbols merge before bodies
check), diagnostics ordered by (file,line,col), new WO-E214 for a name declared
in two files. New docs/plan/oop-vm/01-error-catalog.md (14 emitted + 10 reserved
codes), un-ignored so both plan tracks can cite it; justfile regains woc-*.
builtin_scalars is now the five that work: Int, Bool, Text, Timestamp, Id.
Money/SKU/Float and the abstract_types allowlist are gone — `abstract` never
lexed, and Float had no literal syntax and no wob kind, so no value could exist.
Fixtures and samples retype Money->Int, SKU->Text. The abstract newtype feature
is rejected outright (verdict row adopt->reject); haxe-parity Task 7 keeps `is`.
nullable-types-implementation.md corrected: ?T is plumbed but UNENFORCED
(E211-213 declared, never emitted; probe exits 0), handed to haxe-parity Task 6
as next work item. Records all 10 dead codes incl. E205 — interface satisfaction
is unchecked. crates/rt keeps its Money/SKU fixtures (opaque strings, Stage 2).
Gate: build warning-clean, 14 + 264 checks 0 failures, pricing golden exit 0,
docs/examples histograms unchanged (13/70, zero WO-E225).
