5d0e6635f1 feat: iteration 36 task 4 — runtime bitwise opcodes, .wob v6
- WOP_BAND..WOP_SHR = 42..46 (wob.h), WOP_MAX 46, WOB_VERSION 6
- trap kind WO_T_SHIFT=12: shift count outside 0..63 traps (DIV0
  precedent, never x86's silent count%64); SHR arithmetic
- vm.c: one shared case-body serves both dispatch flavors; SHL shifts
  the unsigned word (wrapping), SHR casts int64_t (sign extends)
- loader.c + test runner battery + disasm: v6 accepted, new opcodes
  validated three-register, rendered BAND/BOR/BXOR/SHL/SHR
- woc-test 543/0, wovm-test ASan both flavors green, cli_smoke OK

771180fd28 feat: iterations 19 + 17 — Float/Bytes scalars (.wob v5), library kind + internal/
- 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.

4a62488bc6 feat: retire RC from the emitter and the format — .wob v4 (7b Phase 3b)
The compiler no longer emits reference-counting ops anywhere, and the format
reserves them. With Phase 3a's collector this completes the runtime half of
iteration 7b: spec success criteria 3 (no RC ops in any image, opcodes
reserved) and 6 (corpus ASan-clean) are met — `just oop-accept` is fully green.

- owner.ml: the rc machinery is deleted outright — rc_site/rc_op types, the
  rcs table, fn_rcs/rc_groups/rc_escaped, record_rc, release_gc, gc_escape,
  resolve_rc, and the clobber rule (its only consumer was elision). The
  `push`-of-a-gc-value RC_INC special case is gone (the bug class cannot recur
  without RC). Drop tables (owned + LGc kinds) are untouched — the gc mask is
  what feeds the collector's root maps.
- emit.ml: emit_rc, the v_rc view, the escape-acquire anchor, and every
  caller deleted; assignment displacing a traced value emits nothing (the VM's
  store barrier owns it); scope-ended LGc handles clear their gc-mask bit so
  root maps stay precise.
- .wob v4: WOB_VERSION 3 -> 4 in wob.h + emit.ml + disasm.ml + the runner's
  loader battery; opcodes 27-28 removed from the enum/jump table/interpreter
  and REJECTED by the loader like any unknown opcode.
- dump.ml: the == RC == owner-dump section is gone; 6 goldens re-blessed
  (owner dumps lose the section, elision.wo's bc dump loses its RC ops).
- runner.ml: rc-table/ELIDED assertions deleted; the elision test now asserts
  the WHOLE image contains no RC op; the table-contract sweep asserts rc ops
  never appear.
- test_unwind.c: the rc-opcodes test becomes two — the loader rejects reserved
  opcode 27, and an abandoned traced instance is freed by rt_destroy
  (ASan-proven).

Verified: woc-test 540/0 + test_diag 14/0; runtime test + test-iso all suites
ASan/UBSan (test_unwind 12/0); cli_smoke; oop-e2e 79/0 (v4 images end to end);
employee 8/0; log-watcher 7/0; ring runs + reclaimed (freed=3) with zero RC
ops in its image; `just oop-accept` ALL CRITERIA MET.

47db5b6cfe feat: secondary indexes + @unique trap (iteration 9, Task 4; wob v3)
- .wob v3: class records carry an index tail (flags bit0 = unique,
  col_cnt, columns) -- @table(index:[a,b]) entries plus one unique
  single-column entry per @unique field; loader validates columns in
  range and scalar/Text-kinded; emitter validates the declarations
  (unknown column, un-indexable kind => diagnostic)
- engine: db_index hash multimap per table, built from the class
  table at first touch, maintained ONLY inside wo_row_insert/
  wo_row_remove; unique checks re-compare actual column values (a
  hash is a hint); replay re-indexes via wo_row_raw_commit AFTER
  slots are filled, so recovered tables carry their indexes
- WO_T_UNIQUE = 10; a violating insert is un-applied whole (bitmap,
  hash, count, and the never-observable id reclaimed) and traps
  catchably -- the employee SEED-DUP pattern
- wo_row_insert gains err_kind so db.c maps UNIQUE/OOM/other to the
  right trap; test images and the runner's loader mirror speak v3
- fixtures: trap/db-unique-violation (code 10 exact) and
  run/db-unique-catch (catchable dup, composite index accepts
  duplicates, next id dense after a refusal)
- gates: oop-e2e 73/0, all 15 runtime suites, woc-test green,
  log-watcher 7/0

ffb8b3b952 fix: net.Conn is a scalar, \r escape, map[k] is optional, interp node ids
Found by driving the compiled log-watcher's third path — the MCP server. It now
answers real JSON-RPC over HTTP: initialize returns protocolVersion/serverInfo,
tools/list returns the full tool list (1049 bytes of generated JSON), and an
unauthorized request gets 401 {"error":"unauthorized"}. corpus 71/0, woc 565/0,
wovm gates green.

- lexer: `\r` and `\0` escapes. Without `\r` a program cannot write CRLF at
  all — the server's `index_of(buf, "\r\n\r\n")` was searching for a literal
  backslash-r, so it never found a header terminator and hung on every request
- parser: an interpolated sub-expression now mints node ids from the OUTER id
  space. A fresh sub-parser started at 1, so `${...}` nodes collided with the
  file's own nodes — and every side table (drops, moves, rc, masks, f_decl) is
  keyed by node id. Surfaced as WO-E404 "ownership table names `headers`,
  which has no register"; silent misattribution otherwise
- types.ml: `net.Conn` is a reserved SCALAR type (a file descriptor). It was
  falling through as "some user class", i.e. WO_K_OWNED, so the frame would
  DROP an integer at scope end
- types.ml: confident_typ knows `..` yields Text. Interpolation desugars to a
  Concat chain, so without it every interpolated value looked underivable —
  which is why the `+`-on-Text check missed two live sites in the workload
- `m[k]` on a map is now the OPTIONAL read (nil for a missing key), while
  `get(m, k)` stays the asserting one that traps KEY. That is what makes
  `let v = m[k]; if v != nil` — the workload's header lookup — work.
  trap/missing-map-key now pins `get(...)`, and the surface doc records the
  split
- json.encode of a `json.Value` emits it verbatim (kind 255): an echoed id was
  coming back as "1" instead of 1
- disasm: TRY/ENDTRY render instead of ?OP32/?OP33
- status board: the push-of-a-borrowed-Text gap is now recorded with the
  concrete failure it produces (tools/call tail_log), plus the leaked
  temporary-record shell found in the same disassembly

ebf82ca9c0 feat: json encode/decode + as, .wob v2 class metadata — log-watcher compiles
docs/examples/log-watcher (1285 lines, 7 files) now compiles clean: 0
diagnostics, a 35KB .wob written. corpus 71/0, woc runtest 565/0, every wovm
unit gate green (both dispatch flavors).

- .wob v2: each class row gains three u32 per-field arrays — the field's NAME
  constant, the CLASS it refers to (or the json-raw marker), and a container
  field's ELEMENT kinds. json is then a runtime service driven by metadata
  instead of per-type generated code. loader/emitter/disassembler/test
  assembler all read and write v2; field-name constants are interned with the
  rest of the pool (interning during serialization silently loses them)
- runtime/src/json.c (new): encode by static kind + object headers + class
  table (nested records need no static knowledge); decode parses and BINDS
  straight into the target class — keys matched to field names, nested objects
  built as the field's class, arrays as a multi of the field's element kind,
  unknown keys skipped, absent keys nil. Malformed input is nil, never a trap
- `as`: `json.decode(text) as T` is the one cast this language has (WO-E403
  for any other `as`, and for a bare json.decode with no target type). Its
  result is `?T`, which is why the decode and the target are one instruction
- json.Value: a reserved type name for a value the source does not inspect —
  the raw JSON slice, kind TEXT, re-emitted verbatim by encode
- docs: 00-wob-format.md is now the v2 reference (class metadata, TRY/ENDTRY,
  the whole builtin surface, WO_T_IO); 08-builtin-surface.md documents the
  text/container builtins, the OS modules with their predeclared records, and
  json's two documented limits (Bool encodes 0/1, floats truncate)

0df9b4fe31 feat(compiler): iteration 5 Tasks 1-4 — modules, language surface, switch, typedef records + enum variants
- Modules: `use`/`pub`, directory-as-module, per-module symbol resolution (a
  flat first-wins merge silently ran the wrong `pub fn` body), six reserved
  stdlib namespaces typed UNKNOWN-BUT-RESERVED.
- Surface: `and`/`or` (own precedence tier, short-circuit, Bool-only), `${}`
  interpolation desugared at parse time, `const`, break/continue with
  drop-correct exits, do-while, inline-fn rejection.
- switch expr/stmt: required `default` over scalars/Text, arm unification,
  EQ/EQS+JZ lowering, per-arm drop scopes with N-way JOIN-DROP; `default`
  sorted last by a shared lowering order (textual order made arms dead).
- typedef records: structural, same shape = one class entry; `?name: T`
  nullable-by-shape; emit_ctor fills omitted defaults; `type` as field name.
- Enum variants: all-bare unions = int ordinals; any-payload = one class
  entry per variant, tag IS the header class_id (no header field, no format
  bump); exhaustive switch without `default`; arity checked both directions.
- Payload escape modeled as move-out (pointer-kind fields only — a scalar
  escape is a copy); caller reaps owned heap temps passed by borrow: two
  unbounded LSan-blind leaks, 10.5 MB -> 1.5 MB flat over 300k iterations.
- Fixed en route, each with a RED repro: dead E209 builtin-arg check and
  `int_to_text` missing from both types.ml builtin tables (both segfaulted
  wovm), multi-file phantom double-report, emit_ctor's field temp clobbering
  dst in tail position (pre-existing), warnings swallowed without an error.
- Two fenced VM builtins: `int_to_text` (13), `variant_tag` (14).
- 14+565 unit (was 14+401), corpus 71 (was 32) plain and under wovm_asan,
  wovm-test + cli_smoke green. Log-watcher 307 -> 93 diagnostics (85 E101 /
  4 E207 / 1 E208 / 3 W202); the 5 non-E101 residuals await Task 7 grammar.

641a41e25c feat: milestone 1 complete — .wob emitter, conformance corpus, single binary; GC redesign specced
- `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.
