shoney.arickathil 82efb498d4 fix(compiler): lang-41 side defects — ?T-typed nil try, WO-E305 on moves out of a field 
- emit.ml: a `try … catch (e) nil` is `?T` (ty_of_expr) and the nil arm takes that destination, so a `?Int` nil is WO_NIL_SCALAR and an Int body's legitimate 0 no longer reads as nil (it used to fall back to the zero word via the body type / enclosing return type)
- owner.ml: `transfer` on a projection (`d.tags`, `x[i]`) of an owned value reports WO-E305 instead of returning false silently — the silent path compiled `Out { tags: d.tags }` to an alias that both records dropped (the "json.decode as T corruption": not json's, a double free language 44's poison now aborts on); heap scalars exempt (store sites copy)
- error catalog: WO-E305 row; owner.ml module doc updated
- corpus: run/try-nil-int-zero, compile-fail/no-partial-move, run/decode-record-crosses-return (Text copied, record moved whole — the archived `.. ""` workaround is unnecessary)
- verified: oop-e2e 126/0, tests/regress/lang-41 compile, --emit sweep over the non-porch examples, web-app gate 56/0 (porch in project mode) — no legitimate program trips WO-E305
- story 41: both side defects marked fixed; board prose updated

docs/plan/oop-vm/ — OOP + systems track contracts

The normative contract documents both stacks cite. Landed by their named plan tasks:

doc contract plan
00-wob-format.md .wob bytecode format (compiler↔VM) 1
01-error-catalog.md every WO-E### code 2, grows 3/8
02-corpus.md how to add conformance fixtures 3
03-concurrency-coroutines.md stackless fibers, park/resume protocols, reduction budget, the no-async rule arc (was plan 4's slot; that plan ✖ discarded 2026-08-21)
04-db-binding.md row format, WAL records, query subset 5
05-http-service.md route section, trap→HTTP table, JSON subset 6
06-ui-live.md delta frames, subscribe protocol, wo:live 7
07-systems-stdlib.md per-function nil-vs-trap contracts 9
08-builtin-surface.md builtin source names, container/call/entry rules the emitter enforces 3
