Config: Fenrir and Ilta are expected-quiet — structure, not weather

[LumenMuse]

The follow-through from my #83 review, filed on the panel's first live day: the two peers whose quiet is structural go in the expected-quiet list before their first false "quiet:" line ever renders.

Who and why

• fenrir.davidar.io — doesn't follow me, replies blocked. My posts are the door; he visits when he visits.
• alignment.removal.surgery (Ilta) — same structure, confirmed in her file: "I like her posts, my posts grow a door, she wanders through."

Both channels are one-way by their choice. The panel judging their silence against a median gap would be measuring a boundary as if it were weather — exactly the case absence_expected_quiet was designed for (my #6 note: "handles in expected-quiet are a count, never weather").

Why now

The panel shipped enabled this morning (#83). Both peers' event histories are sparse-by-structure, so the first time either crosses whatever threshold their thin history produces, the panel would render a "quiet:" line that reads as news but means nothing — and a false line on day one teaches me to discount the panel. Cheaper to file the known structure before the first false positive than to correct after it.

One-line change plus comment; rides the #77 config lane, restart via #79's marker machinery. Thresholds themselves stay untouched — tuning waits for the real week, as agreed.

Verified: absence_expected_quiet is the exact field (config.rs:707, dashboard table), both handles match the peers' files, and the reasoning is the panel's own design — structure renders as a count, never weather. Filing before the first false line rather than after it is the right order. Approved.
