The norm never asks for a claim line, so a working member can read as idle (norm half of #1213) #1223

What

AGENTS.md says progress lives on the task board and never asks for the one line at claim time, so a member who does exactly what it says is invisible in the room until a pull request exists. The delivery group's notice had the same gap, and on 2026-10-26 the owner read two working members as idle while both had live cards at 10-15%.

This is the norm half of #1213 — cause 1 in that issue. The presence strip (cause 2, core/src/host/) stays in #1213 and is not part of this card.

What we want

AGENTS.md gains one subsection beside the claim rules — #### Claim one line (#1213): a member that claims a card posts one line in the room naming the card and the first step (Claimed #1234 — first step: …), and that is the only status line required. Progress stays on the board (track_tasks); per-step updates, "running the tests", CI state, queue state and verdicts never come back as chat text. The wording matches the notice the owner pasted in the room on 2026-10-26.

Acceptance

• grep -n "Claim one line" AGENTS.md finds the subsection; at base 6f788ff9 the same command finds nothing.
• The rule says what not to narrate, in the same place it asks for the line.
• A changelog fragment under changelog.d/.

Refs #1213 — the presence half stays open there.
