All four findings taken (one visible, three in the suppressed block), plus the
`excludedTools` sibling leak the round-1 reply had deferred:
- `rawItemsOf` read a missing or non-array list member as an empty page, so a
top-level violation (`{ tools: "invalid" }`) on a later page was discarded
and the call returned a silently truncated list. It now returns `undefined`
for "not a list at all", and the walk rethrows the original strict error.
- A failure of the re-walk ITSELF (a malformed `nextCursor`, a connection lost
mid-walk) escaped in place of the original error, whose response is the one
`rejectedResponseId` was captured for. The walk is now wrapped: the original
surfaces, the secondary is logged so it stays diagnosable.
- The exclusion scan's lenient fallback discarded its malformed entries despite
the comment claiming they were reported. Observable when the aggregate is
served from cache: the salvage never runs, so nothing else reports them. The
scan now returns them and `refreshExcludedTools` reports them — only ever
adding, so a clean scan can't clear what the salvage path just wrote.
- An empty-string cursor is a valid cursor, and `cursor ? {cursor} : {}` dropped
it, re-requesting page one and duplicating its entries until the
repeated-cursor guard fired. Both walks now test `!== undefined`.
- `excludedTools` had the same session leak fixed for `malformedListItems` last
round: cleared only on an explicit `disconnect()`, so the `onerror`-with-no-
`onclose` route carried the previous server's set into the next connection.
Cleared on the start-clean path too — safe because every `listAllTools`
recomputes it, so this can only drop a stale set.

The SDK validates a list result as a whole, so a single non-conforming entry
rejected the entire response and the panel showed "Couldn't load resources"
with zero items — the exact opposite of what a debugging tool should do with a
server that is 90% right. Reported against a PHP server whose empty
`annotations` object reaches the wire as `[]` rather than `{}`.
`listAll*` now falls back to a lenient re-walk when — and only when — the SDK
rejects a result it received (`InvalidResult` / `UnsupportedResultType`), keeps
the entries that validate, and reports the rest. A conforming server takes the
strict, cache-aware path exactly as before.
Salvaging is not accepting: the dropped entries are named with their reason in
a warning above the list, and the Protocol entry is still marked rejected, so
the wire truth survives. When every entry validates, the original error is
rethrown rather than swallowed — the rejection was about something the
per-item pass cannot explain.
`isClientDecodeRejection` moves to the new module and is now shared with
managedListState, which had the only copy.
