- done/ (11): 1, 2, 3, 4, 6, 7, 7b, 9, 9b, 15, 16 — landed iterations
(9/9b remainders live in the post-12 drain list, not in the files)
- refine/ (8): 9c, 9d, 9e, 9f, 9g, 11, 13, 14 — everything marked
"no spec yet / brainstorm before planning"
- root keeps: 00-story (index), 05 (partial, plan 8 open), 8/10/12
(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
crosses to refine/)
- 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)

- 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

- 9b spec gains section 6 "Ownership, borrows, and GC across the
engine boundary": two one-way copy gates (no VM pointer enters a
row, everything a select returns is copied out), so the collector
never traces engine memory and the engine never touches refcounts
- row views are borrows WITHOUT a runtime net: rows share the VM's
field encoding but not its header, so no borrow word backs them --
the compile-time escape rule is load-bearing alone
- cursor stability settled: scans materialize their id list before
the body, row updates through the view stay legal (raise mode
updates an indexed column mid-scan and is the proving fixture),
insert/delete on a table with an open cursor is a new WO-E5xx
- GC-pause interaction recorded: collector runs between statements,
a long scan delays slices -- accepted, documented
- iteration-7b ordering constraint: GC inference must classify before
table-field validation, diagnostic names the inference reason --
noted in 7b story, iteration-9 plan constraints, 9b plan tasks
- stories 09/09b Info sections point at the analysis; 9b plan Tasks
3/5 carry the enforceable checkboxes (ASan boundary assertion)

- spec settles 9b's three forks: SQL/Cypher layer superseded as the
program surface (design history + wo-db engine-semantics reference);
comprehension syntax desugared at compile time (no function values);
System.Linq = operator vocabulary + edge cases, PostgreSQL = execution
+ integrity vocabulary (both references surveyed 2026-08-15)
- aggregate semantics normative: count/sum total 0 on empty, avg/min/max
are ?T with nil (empty is data, not a fault); nil skipped; sum wraps
like language arithmetic; GroupBy lowers as group-and-reduce
(AggregateBy shape), transition/finalize ABI from nodeAgg
- relations: ref = FK with direct-index-probe check (nil passes,
unchanged-key skips), backlink = secondary-index scan, delete is
restrict-only; nil never joins, nil is a legal group key
- lowering: the compiler is the planner — queries become bytecode loops
over cursor/group builtins, longest-prefix index selection, no plan
tree, no SQL text in the image (disassembly-provable)
- plan: 6 tasks gated by a new docs/examples/employee sample
(Department/Employee, @unique, composite index, ref/backlink,
GroupBy report mode) with its own acceptance script + crash step;
blocked on iteration 9's engine plan
- story 09b + status board updated; 02-wo-language.md carries the
supersession note

- `woc` now emits `.wob` that `wovm` runs: emit.ml lowers the typed,
owner-annotated AST (scope-stack registers with a >64 WO-E401 diagnostic,
Lua-style call windows, ICALL by slot, dedup const pool, drop maps, line
tables, implicit terminators); disasm.ml backs `--dump-bc` goldens.
- Ownership lowering consumes the four owner tables verbatim; RESIDUAL is the
only source of borrow ops, coalesced per operand. Review caught the emitter
consuming only 2 of owner.ml's 4 residual producers — an assignment-anchored
aliasing violation ran to exit 0 instead of trapping; fixed, plus a backstop
raising WO-E404 for any residual region left unconsumed.
- Conformance harness `scripts/oop-e2e.sh` (`just oop-e2e`): four fixture
kinds with exact outcomes — byte-exact stdout, one WO-E### anchored on
`error CODE:`, numeric trap code, gc trace. 25 fixtures incl. pricing-demo
logic, the ownership suite, and DB_STUB's parse-but-trap. `tests/` un-ignored
so the corpus is actually tracked.
- `woc build` produces a self-contained binary: wovm copy + appended image +
20-byte trailer, self-exec via /proc/self/exe. Verified relocated outside
the repo, argless, and against adversarial trailer corruption.
- Milestone 1's five spec criteria all MET (`just oop-accept`). Criterion 3
closed by WO-E405 — the entry must return `Int`, since program mode already
says its return value is the exit code — which deletes the leak class
without adding return-type metadata to the format. `gc/held-cycle` retired:
an externally-held cycle is not expressible in a post-exit pump.
- New spec: inferred GC + incremental per-shard tri-color mark-sweep, retiring
`@gc` and reference counting. Story gains iterations 7b (that work) and 9b
(`@table`, relations, compiler-checked query); `.dev/reference` gains a
sparse System.Linq checkout. Priority: 5→6→7 (log-watcher) then 7b, 8, 9, 9b.
