Additive test coverage across server, editor-ext, client and mcp.
#192 — AiChatService.stream integration (Section 3, against real Postgres):
- new apps/server/test/integration/ai-chat-stream.int-spec.ts drives the real
streamText through a seeded ai/test MockLanguageModelV3 and a real Node
ServerResponse, covering: onError persists an assistant error record
(status 'error' + partial answer + provider cause in metadata); external MCP
client closed exactly once on BOTH onFinish and onError; anti-tamper —
history is rebuilt from the DB transcript, not from body.messages.
#206 — red-team findings (most already fixed+tested in #212):
- mdrt-2 (UNFIXED, data loss): turndown.dataloss.test.ts documents that
pageBreak / transclusionReference / mention are silently dropped on Markdown
export (characterization + it.fails for the desired survive-export contract).
- persist-6 (UNFIXED, data loss): persistence-store.spec.ts adds an it.failing
documenting that a momentarily-empty live doc overwrites non-empty content
(left unfixed — a store-side empty-guard is a behaviour change).
#204 — test-strategy plan, highest-priority subset:
- Phase 1: mcp-clients.lease.spec.ts covers the external MCP client
lease/refcount/eviction lifecycle (leak / premature-close / double-close).
- Phase 2 data-integrity pure functions: editor-ext table-utils
(transpose/moveRow/convert round-trip) and math tokenizer false-positive
guard; client emoji-menu (+ it.fails for the unguarded localStorage
JSON.parse bug), sort-cells, normalizeTableColumnWidths; mcp htmlEmbed/
pageBreak markdown data-loss + footnote-diff; server export
getInternalLinkPageName extensionless-path bug — FIXED (small/clear) + tested.
