Progressive enhancement on body in the shell base sheet so mixed
Chinese/English copy gets consistent spacing without content edits;
engines without support ignore the property.
A title now comes from an attached session's live projection cut or a cold
one's durable checkpoint, and from nothing else. Attachment is decided by the
session store at read time, so a session that attached after the listing is no
longer answered from a checkpoint its log has moved past — the stale-title case
`api-session.list` already handles this way.
The log fold and its per-log memo are gone. Folding one title costs a whole
log, and this call sits under every keystroke; a session no projection answers
for is labeled by its id and regains its title the first time it is opened.
`lib` leaves the default exclusions: Ruby gems and many npm packages keep
sources there, and the miss would be silent and total. A traversal whose root
is unreadable now rejects instead of publishing an empty index over entries
that are still good, which is what the stale-while-revalidate path claimed but
could not do while every readdir error was swallowed. A drill marks the menu
drilled only when its edit actually reached the draft.

Review found the shared observation defeated the very fence it fed:
it carries the original PID-to-start-time pairing forward, so a
recycled PID still matches it and takes a signal meant for the process
that exited. Capturing it outside the per-member try also let one
failed read abort a whole teardown round, breaking the synchronous
host-exit contract, and an empty round paid a read for no members.
signalProcess now reads ProcessInspector.isAlive immediately before
delivering, from the narrowest per-identity source each platform
offers; signalMembers and waitForMembers return before capturing when
a round has no members. snapshot() keeps serving the readiness poll,
whose per-poll table read stays at one.
Windows enumerates Toolhelp32 lazily on the first tree question, so a
snapshot asked only for liveness — the 25 ms teardown poll — performs
no table walk at all.
TurnNavigator was an unmemoized component rendering one div and one
button per loaded Turn, so every ChatView render rebuilt the whole rail:
143 button rebuilds per commit in a 300-Turn session against 8.4 in a
4-Turn one, while a streaming answer commits dozens of times.
memo alone would not have helped, because navigateToTurn was rebuilt on
every render and broke prop identity, so it moves into useCallback.
MacProcessInspector answered the descendant tree and every member's
liveness with its own `/bin/ps` fork, so one readiness poll cost N+1
full table reads for N tracked descendants. With execFileSync on that
path and a 50 ms poll interval, any command spawning two or more
children saturated the host event loop until it exited.
ProcessInspector.snapshot() now returns one ProcessSnapshot that
answers tree, session, and alive from a single observation, and
signalProcess takes the caller's observation so its PID-reuse fence
does not re-read the table per member.
Collapsing every relative-time bucket to `{{age}}` reached the session-tree
goldens, where a literal age is the assertion: a fresh row reads `now` and an
older one does not. Six e2e files failed, two of them by aborting mid-scenario
and leaving their replay fixtures half-consumed.
`captureStableAria` now takes the rule as an opt-in, and only the reference
menu — whose rows are dated from the live Host list — asks for it.
