Exercise 1: Why "Still Investigating" Is Genuinely Valuable — Possible Solution
====================================================================

WHAT SILENCE COMMUNICATES INSTEAD
------------------------------
Per this chapter, "the absence of an update during an active incident
isn't neutral - anyone waiting interprets it, usually as neglect
rather than 'actively investigating something genuinely hard.'"
Silence doesn't read as "no news" to the people waiting - it reads as
"nobody is working on this," an actively wrong and damaging
interpretation.

WHY A CONTENT-FREE UPDATE STILL PREVENTS THIS
------------------------------
Per this chapter, "'still investigating, no new findings yet' is
itself real, valuable information worth sending, even when there's
nothing new to report." Sending this message directly replaces the
wrong interpretation (neglect) with the correct one (active,
ongoing work) - even though the message contains no new facts about
the incident itself, it corrects a false belief the silence would
otherwise create.

WHY THIS MEANS "NO NEW FINDINGS" ISN'T THE SAME AS "NOTHING TO SAY"
------------------------------
The value of the message isn't in reporting new findings - it's in
confirming that work is ongoing. Those are two separate pieces of
information, and a message can deliver the second even when it has
none of the first. Treating "I have nothing new to report" as a reason
not to send anything conflates the two.

WHY THIS WORKS AS AN ANSWER
------------------------------
It explains specifically what silence is misread as, and explains how
a content-free "still investigating" message directly corrects that
misreading rather than simply being a courtesy, distinguishing between
reporting new facts and confirming ongoing work.
