Validated in a combined 2-PR batch worktree off release/v3.8.51 tip (companion fix to #11473, merged first).
- Focused tests: chat-log-array-tail-items-default, chatcore-log-truncation, request-logger-bounded-clone, request-logger-bounded-idempotence, repro-7847-bound-client-raw-request — part of batch's 46/46 node:test run
- typecheck:core, file-size, changelog-integrity, complexity, cognitive-complexity — all OK
- Full-repo lint: 228 pre-existing dashboard react-hooks/* findings, unrelated to this diff
Thanks for unifying the two independently-drifted truncation caps onto one configurable source — measured evidence that the storage ceiling comes from retention days, not the per-item cap, makes the 128→1000 raise a clear correctness improvement.
requestLogger.ts's cloneBoundedForLog had its own hardcoded depth cap of 6,
independent of the existing configurable getChatLogMaxDepth(). A typical
Chat Completions response body's responseBody.choices[0].message.tool_calls[0].function
sits at exactly depth 6, so every logged tool call's function field
(name+arguments) was silently replaced with the literal string "[MaxDepth]"
before ever being stored — corrupting the data, not just how it renders.
Bumped the shared default 6->20 and switched requestLogger.ts to read it
instead of using its own literal.
