Capture the five debugging chapters from the bearer-forwarding rollout
so the knowledge doesn't live only in chat history:
1. Per-request bearer across anyio.TaskGroup boundary (ContextVar
snapshot semantics, httpx auth-header caching on persistent
connections, forward_inbound_auth pydantic-drop workaround).
2. install() idempotency guard shadowing three newly-added
monkey-patches — each patch now owns its own sentinel.
3. FastMCP on_call_tool context shape: context.message.name, not
context.message.params.name. Extractor returning None silently
killed the _PUBLIC_TOOLS bypass and downstream dispatch "await
None(...)" produced the terse 'object NoneType can't be used in
await expression' string that blocked Harper<->Mnemosyne.
4. Rich-TUI corruption by DEBUG openai/sse_starlette/mcp via root
logger inheriting logger.level=debug + our stderr StreamHandler.
Fixed by PALLAS_LOG_STDERR gate and PALLAS_ROOT_LOG_LEVEL split.
5. Current state table of PALLAS_LOG_* knobs + jq tail recipe.
Also add pallas.log and pallas._fastagent_patch to the Module Reference
table.
