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

- 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

docs/examples/log-watcher now COMPILES AND RUNS: `wovm lw.wob watch app.log 2 1`
tails a live file, classifies levels and fires its alert
("last entry is error, quiet for 2s"). corpus 71/0, woc 565/0, wovm gates green.
- program mode: the entry is `fn main` taking nothing or one `multi Text`;
runtime/src/main.c builds that list from the program's own arguments (not
the program name, not the image path) and the entry's return value is the
process exit code (low byte); the loader accepts a 0- or 1-arg free-fn entry
- `+` on Text is now WO-E201 pointing at `..`. This was a memory-safety hole,
not a style nit: the emitter lowered it to ADD on two heap pointers, and the
workload's own `out = out + char_of(c)` produced a wild pointer that
segfaulted the VM inside starts_with. Reported off confident types only
- `x == nil` / `x != nil` lower to EQ (a word compare), never EQS: nil is the
zero word and EQS dereferences its operands, so a nil guard would trap
instead of answering
- docs/examples/log-watcher: seven `+`-on-Text sites corrected to `..`
(logtail sanitize, mcp header/body/carry assembly, supervisor detections
line) — the sample was carrying the Haxe habit, and the language reserves
`+` for arithmetic by doctrine
- wovm CLI takes arguments after the image path (`wovm <file.wob> [args...]`)
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- `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.
- Board renamed docs/plan/00-kanban.md -> docs/00-status.md and rebuilt: ▶ NEXT
PLAN pointer (iteration 4 — emitter, corpus, `woc build`) then six buckets —
stories, in progress, done, pending, discarded, learnings. It covered only the
Rust runtime before, so the whole OOP track was invisible. All 16 inbound refs
repointed; `Kanban:` banners renamed to `Status:`.
- New discarded.md (settled rejections with reasons: inheritance, `abstract`,
Money/SKU/Float, Dynamic/cast/macro/extern, AOT-to-C, Menhir, shared engine
state) and learnings.md (plumbed≠enforced, vacuous goldens, exit-0-wrong-
output, malloc-path ASan trick, deferred checks that never reach the VM).
- RECOVERED docs/plan/exploration/blue-green-vm/00-vision.md — gone from disk,
never committed (gitignored path), cited by five docs incl. principle 12.
Root cause was broader: all seven forward-roadmap plans in
docs/superpowers/plans/ were untracked and ignored, on one disk only. Dropped
the docs ignore rules with a do-not-re-add note; added __pycache__/*.pyc.
- Repaired broken links across docs/, 270 -> 36: fixes a regression from the
earlier reference/ -> .dev/reference/ move (relative paths at ../../ and
deeper were skipped), plus depth and reorg drift. The 36 residual point at
content that does not exist and need decisions, not paths.
- New spec docs/superpowers/specs/2026-08-10-logwatcher-gap-closure-design.md,
applied: `and`/`or` verdict row; Part 3 gains `env` (six modules), swaps
time.mono for iso/local, adds 22 bare core builtins; throw/time.mono/is cut
(0 uses in the sample). Plan 8: Task 2 gains and/or, Task 5 drops throw,
abstract+`is` task deleted, 8/9 renumber to 7/8. Plan 9 gains core builtins.
Plan 10 gains the 307 -> 0 diagnostic gate. WO-E205 re-filed unreachable-by-
design. types.ml header drops its false satisfaction-set claim. 00-code-
review.md reduced to a stub — its rival Phase 1-4 roadmap retired.
