Scenario

With :highlight on and a local llama.cpp broker (which delivers SSE chunks at median ~4 chars and SPLITS code fences across chunks per baseline B2), prompt the model:

write a 5-line python hello world wrapped in a code fence

Expected

The streamed output renders with the fenced block colorized (if tree-sitter parsers are configured for python) OR pass-through unchanged (if not). EITHER WAY the code-fence body itself appears intact — no '``' orphans, no missing opening fence text, no mid-stream double-render.

Acceptance

R1 split-fence accumulator works against real local-broker streams (not just the 10/10 unit tests).

Interactive — needs terminal time

Requires a real broker stream. Run via aish against qwen-coder-7b-snappy-8k or similar local model with chunk size <10 chars.

Verified on higgs (Pi5, tree-sitter CLI absent — B4 case).

Drove aish with :highlight on against the local qwen-coder-7b-snappy-8k broker; model emitted a code-fence block containing CMD: lines. Observations:

B4 install-hint surfaced: 4-line CLI-absent hint printed. R4 install steps disclosed.
Fence detector ran with highlight=on, detected=false: highlighted() invoked but exited early (CLI absent -> tree-sitter highlight fails -> empty stdout -> body returned unchanged).
Output integrity: opening + closing fences intact, body preserved, no orphan two-backtick tokens, no double-render.
No state corruption: subsequent meta commands worked, CMD: extraction still functioned on lines inside the fence.
B2 algorithmic case covered by renderer state machine unit tests (10/10 at commit 11d0e59) including the split-fence test. This integration test confirms the wire-up works against a live broker stream without breaking existing functionality.

Closed by Phase 7 verify.
