FAIL — rle submodule: 8 test failures (string Display format change)

All 8 failures are expect-test snapshot mismatches caused by a MoonBit toolchain update that dropped quotes from String/Char display in Show output:

- Some("hello")
+ Some(hello)

- ['h', 'e', 'l', 'l', 'o']
+ [h, e, l, l, o]

- Ok("ell")
+ Ok(ell)

Affected files: rle/src/runs_test.mbt:225,233, rle/src/rle_test.mbt:227,234, rle/src/README.mbt.md:57,124,205,440

Fix: Run moon test --update inside rle/ to regenerate snapshots, then push a submodule update.

FAIL — loom/examples/{lambda,json,markdown}: Build error [4014] type mismatch (Derived vs Memo)

All three example packages fail to compile with:

Expr Type Mismatch
  has type : @dowdiness/incr/cells.Derived[_]
  wanted   : @dowdiness/incr/cells.Memo[_]

Root cause: the incr submodule (pinned at 219b9e65) appears to have renamed or split Memo → Derived in its API, but the loom example packages haven't been updated to match. This is a cross-submodule API break.

Affected: loom/examples/lambda/src/callers/, loom/examples/json/src/, loom/examples/markdown/src/

Fix: Update call sites in loom examples to use Derived (or whichever the current type is), or align the incr pin to a version that still exports Memo.

WARN — moon check: 62 deprecation warnings

Recurring patterns across editor/ and relay/ packages:

• @buffer.new() → use Buffer() instead
• Buffer.write_string() → use StringBuilder or explicit Buffer encoders

These are non-blocking but will become errors in a future MoonBit release. Files: editor/ephemeral_encoding.mbt, editor/ephemeral_hub.mbt, editor/sync_editor_ws.mbt, editor/sync_protocol.mbt, relay/wire.mbt.

WARN — moon fmt --check: deprecated moon.mod.json migration notices

moon fmt --check exited non-zero with migration warnings for 8 modules:

Warning: Migrating to moon.mod at module root '/home/user/canopy', deprecated moon.mod.json is removed.

Affected: root, lib/btree, lib/dom-boundary, lib/moji, lib/rabbita_codemirror, lib/text-change, lib/visualizer, lib/zipper.

This is a formatting/toolchain migration drift — run moon fmt to resolve.

---

WARN — Submodule: rabbita SSH nested submodule

rabbita/templates/rabbita-template is configured with a SSH URL (git@github.com:moonbit-community/rabbita-template.git). This cannot be cloned in HTTPS-only environments (CI, remote dev containers). Non-blocking since rabbita/rabbita tests pass without it.

---

Stale Branch Candidates

None — only main branch exists locally. The repo is on a detached HEAD with 35 commits ahead of origin/main; those commits have not yet been pushed.
